EEVISION OF THE OETHOPTEEAN GEOUP MELANOPLI 
 (ACEIDIIDAE), WITH SPECIAL EEFEEENCE TO NOETH 
 AMEEICAN FOEMS. 
 
 By SAMUEL HUBBAED SCUDDEE. 
 
 INTEODUCTION. 
 
 THE PEESENT ESSAY describes iii detail and discusses the classifi- 
 cation of a group of grasshoppers which forms the prevailing type of 
 orthopteran life throughout North America the common short-horned 
 grasshoppers one sees every summer day. Its best known representa- 
 tive to the world at large is the destructive migratory locust of the 
 West, the so called "Eocky Mountain Locust." The outbreak of this 
 insect has been at times extremely disastrous; so much so that a Gov- 
 ernment commission was for several years in existence, which pub- 
 lished nearly twenty years ago two voluminous reports in which it and 
 on or two of its immediate allies were studied with a minuteness and 
 thoroughness, and illustrated with a fullness very rarely given to any 
 such insignificant looking creature. 
 
 This destructive insect has numerous closely related allies in all parts 
 of the United States, many of which often abound to such an extent as 
 to do serious damage to crops, and a few of them have been known to 
 migrate in similar fashion (though over a far more restricted area), so 
 that they have sometimes been mistaken by the uninstructed for that 
 destructive pest. 
 
 The group is almost confined to North America, and a great many 
 species have been described by various writers in a more or less desul- 
 tory manner. It is the aim of the present paper to enlarge and sys- 
 tematize our knowledge of this important group as a basis for future 
 studies. No group of North American Orthoptera has been in greater 
 need of revision.

 and ' twftittitictis. Stated as briefly as possible, the 
 Melanopli are Acridians in which the antennae are longer than the fore 
 femora, which have no foveolae on the vertex, the fastigium more or less 
 deflexed, passing insensibly into the frontal costa, the prosteruum 
 mucronate, no sharp and distinct lateral carinae (or they are rarely 
 present), an arolium on all the tarsi, the hind tibiae with smooth mar- 
 gins, provided with 9-14 (by rare exception 8) spines regularly disposed 
 in the outer series, which lacks an apical representative, and the second 
 hind tarsal joint only half as long as the first. 
 
 To state their characters more in detail, theMelauopli may be described 
 as Acridians, generally of small or medium size, never very large, in 
 which the head is not greatly exserted and the face is moderately oblique 
 or subvertical; the antennae are linear, longer than the fore femora; the 
 eyes are of moderate size, not very strongly prominent, never twice as 
 long as the infraocular portion of the geuae, the interspace between 
 them very rarely broad, generally narrow; the fastigium is more or less 
 decliveut, never greatly produced in the axis of the body, apically entire 
 and with no transverse ruga, passing insensibly and with obtuse arcu- 
 ation into the frontal costa; the latter is hardly rounded as seen from 
 the side, percurrent or subpercurrent, generally sulcate, the sulcation 
 ordinarily confined to the lower portion; without foveolae, the teinpora 
 small, obliquely declivent, confused with the front; the superior ocelli 
 more distant than the antennal scrobes ; the lateral carinae of the face 
 nearly equidistant from the lateral margins of the frontal costa, but 
 slightly divergent inferiorly. The dorsum of the pronotum is nearly 
 plane and without a crest, generally with no distinct lateral carinae, but 
 at most with rounded shoulders or feeble rugae to represent them, but 
 often passing insensibly into the lateral lobes ; the principal sulcus is 
 continuous; the prozona is generally smooth or obsoletely punctate, 
 never tuberculate, its sulci generally feebly impressed, often mesially 
 interrupted or subinterrupted, the posterior sulcus often distinctly 
 divergent laterally from the principal sulcus; the metazona is generally 
 shorter than the prozona and lies in the same or nearly the same plane 
 with it, almost always densely punctate; the lateral lobes are truncate 
 or subtruncate posteriorly, with no humeral sinus or only a feeble one, 
 the posterior lower angle distinctly obtuse. The prosteruum is armed 
 with a spine which is usually rather prominent and conical, sometimes 
 truncate, never sinuate, generally vertical on the posterior face, nearly 
 or quite as high as the anterior coxae, the posterior portion of the pro- 
 sternum not or but slightly tumescent; the mesosternal lobes are quad- 
 rate or transverse, separated more or less widely, the apical inner angle 
 rectangulate or obtusangulate, generally rounded (often obtusely), the 
 inner margins generally rounded, often posteriorly divergent; the meta- 
 sternal lobes are contiguous or not very distant excepting sometimes 
 in the female and then rarely as distant or even nearly as distant as

 the mesosterual lobes. The tegmina are frequently abbreviate or even 
 wanting; when fully developed, they taper gently almost throughout 
 and are rather remotely reticulate at least in their apical half, the cells 
 of the postradial area wholly or partially biseriate in arrangement on 
 either side of an intercalary vein; the wings are almost always clear 
 and uniform, never definitely pictured, the veins never scalariform, the 
 areolae quadrate or longer than broad. All the tarsi are furnished with 
 an arolium, the front legs are less distantly separate*:! than the hind 
 pair, the fore tarsi are of moderate length, the first joint short or rather 
 short; the hind femora are distinctly incrassate basally, generally sur- 
 pass the abdomen, the upper face generally smooth, the dorsal cariua 
 entire, unarmed, not profoundly excised before the geuiculation; the 
 hind tibiae have smooth lateral margins, the spines of the outer and 
 inner paries are equal or subequal in length, those of the outer series 
 typically nine 1 or more in number, rarely exceeding fourteen, placed at 
 subequal distances apart and lacking an apical spine next the calcaria; 
 the hind tibiae have the first joint not compressed, equal to or slightly 
 longer than the third, the second much shorter, generally a half shorter,' 
 than the first as seen from above. The second dorsal segment of the 
 abdomen is neither granulate nor dentate at the anterior angles, the 
 extremity of the abdomen in the male generally more or less clavate 
 and recurved, the supraanal plate not tuberculate, with a basal median 
 sulcus, a furcula usually present, the cerci very variable, rarely longer 
 than the supraanal plate, straight or gently curved, never abruptly 
 recurved basally, generally compressed at least in part, often laminate, 
 but with no iudirected median spine. 
 
 The foundation for our present knowledge of the structural features 
 of the Melanopli was laid by Stal 2 and enlarged in his Systema 
 Acrideodeorum (1878) and his Observations Orthopterologiques, lit 
 (1878). In its present form the group was first defined and named by 
 Brunner von Wattenwyl, 3 who applied to it the term PEZOTETTIGES. 
 I have here limited it strictly in the same manner, but it will appear 
 that it contains a very much larger number of generic types than were 
 credited to it by Brunner and a vast multitude of species. I shall 
 moreover show below, when treating the genus Podisma, 4 that the gen- 
 eric term Pezotettix, from which Brunner derived the name of the 
 group, has been misapplied of recent years, and should be referred to 
 the group called Platyphymata in Brunner's Revision. I have accord- 
 ingly here named the present group MELANOPLI after its predominant 
 genus MelanopluSj the species of which far outnumber all the others com- 
 bined. Giglio-Tos in recent papers has described several new genera and 
 
 1 By exception, in one sex or on one side of the body, there may be only eight.

 species from South America; but in the present paper full consideration 
 will be given only to the North American species; a table will, however, 
 be added for the determination of the Old World species in their place, 
 and the South American forms will be merely tabulated at the close. 
 
 Geographical distribution. The Melanopli are an almost exclusively 
 American group; a single genus, Podisma, is represented in the Old 
 World (and more abundantly than in the New) north of 35 north lati- 
 tude. With that exception almost all the genera and species are confined 
 to North America. South America possesses four genera (not included in 
 the present paper) Dichroplus, Scotussa, Scopas, and Atrachelacris, with 
 about twenty known species mostly referred to Dichroplus, besides 
 ParadichropluSj with four species in Paraguay. The remaining genera 
 are exclusively North American, but eleven of them Netrosoma, 
 Phaedrotettix, Conalcaea, Barytettix, Phaulotettix, Geplialotettix, Rhab- 
 dotettix, Cyclocercus, Sinaloa, Aidemona, and Philocleon, with nineteen 
 species, besides two species of the South American genus Paradichro- 
 plus, are found exclusively in Central America and Mexico, or only pass 
 the borders of the United States narrowly. 
 
 All of these Central and South American genera (with the single 
 exception of Philocleon) belong to the division of Melanopli in which 
 the lateral margins of the subgenital plate of the male are not at all 
 ainpliateatthebase; and they corn prise all but three of the genera belong- 
 ing to that section, these three being Gymnoscirtetes with one species in 
 Florida, Hypochlorawith one species from the Canadian border to Kansas 
 and Colorado, and Campy lacantha with four species, three ranging 
 from Nebraska to Texas and one found in Mexico. The great bulk of 
 the species and most of the genera (including all but one Philocleon 
 of those belonging in the section with ampliate basal margins to the 
 subgeuital plate) are confined to the United States and Canada, where 
 they form one of the dominant types of Acridiidae. 
 
 This division, that with ampliate basal margins, is represented (apart 
 from Philocleon with its single species) by fourteen genera and one hun- 
 dred and seventy-nine species, of which only four genera occur south 
 of our border, with thirteen species confined to Mexico, and twelve 
 others found both in Mexico and the United States; leaving ten genera 
 wholly, and four others almost wholly, belonging to the more northern 
 region, with one hundred and sixty-six species. No species of either 
 division are found in the Antilles. 
 
 With trifling exceptions, then, the division with nouarnpliate basal 
 margins to the subgenital plate is characteristic of Central and South 
 America or subtropical and tropical America while the other divi- 
 sion, vastly more important, is characteristically temperate North 
 American, with one outlier in temperate Europe Asia. 
 
 The dominant genus is Melanoplus with one hundred and thirty one 
 species described in the present paper; a number more are known to

 me, but insufficiently. Podisma follows, with about twenty-four 
 species, of which only eight are found in America, then Aeoloplus with 
 ten, Hesperotettix with eight, and Bradynotes with seven. The remaining 
 genera have at the most only three or four species each, and fourteen 
 of them are monotypic. 
 
 The genera with widest latitudinal range (over twenty degrees) are, 
 primarily, Melanoplus, and tben Hesperotettix (eight species), PJtoc- 
 t nluttes (one species), Oedaleonotus (one species), Campylacantha (four 
 species), and probably Podisma (eight species). Aeoloplus (ten species) 
 follows hard after. The genera characteristic of the United States, 
 with narrowest known limits, are Gymnoscirtetes and Eotettix, both 
 known only from Florida. These last two, with Paroxya and Apteno- 
 pedes, are the only genera (with eight species between them) confined 
 to the eastern United States, if Texas may be included in that term, 
 for they do not extend west of that. Most of the genera are western, 
 using that term in a broad sense, though Hypochlora, Campylacantha, 
 Dendrotettix, Paratylotropidia, and PhoetaUotes all but Campylacantha 
 monotypic genera are peculiar to the Mississippi Valley, though prin- 
 cipally to its western half. The only genera found across or almost 
 across the continent, or at all events on opposite sides of the continent, 
 are Melanoplus, Hesperotettix, and Podisma. Aeoloplus (ten species), 
 Bradynotes (seven species), Poecilotettix (three species), Oedaleonotus 
 (one species 1 ), and Asemoplus (one species) are characteristic of the 
 extreme West. Finally, Hypochlora (one species), Bradynotes (seven 
 species), Podisma (eight species), and Asemoplus (one species) are con- 
 fined or nearly confined to the region north of latitude 35. Podisma 
 has also the same limitations in the Old World. Regarding the distri- 
 bution of Melanoplus, with its great preponderance of forms, further 
 details will be given under that genus. 
 
 There are but few species which range across the continent, yet not 
 a few have a very wide distribution. The examples of the former are 
 wholly confined to Melanoplus: M. atlanis, fasciatus, femur-rubnim, 
 extremus, minor, tmdfemoratus, M. extremus only in the high north. As 
 illustrations of the latter may be mentioned Hesperotetiix pratensis, 
 PhoetaUotes nebrascensis, Paroxya florldana, Oedaleonotus enigma, and 
 the following species of Melanoplus: flabellifer, spretus, scudderi, daw- 
 soni, cinereus, packardii, luridus, differentialis, bivittatus, and punctula- 
 tns. Most of these range more widely from north to south than from 
 east to west. About three fourths of all the species are known from 
 west of the Mississippi River only. 
 
 J)imorphism in length of tegmina. We find in the Melanopli every 
 variation possible in the length of the tegmina, but the species are ill 
 general tolerably well fixed in this respect. The same is the case with 
 most of the genera, the species of which are in each case generally 
 apterous, provided with lateral pads, abbreviated tegmina, or fully 
 
\

 developed tegmina, as the ease may be; but all the larger genera (except- 
 ing Bradynotes] and some of the smaller show considerable diversity in 
 this respect; the greatest difference between different members of the 
 same genus obtains in the two largest genera: Melanoplus. where the 
 species may range from those with merely lateral pads to those with 
 tegmina far surpassing the hind femora; and Podisma, where they 
 range from apterous species to those with tegmina half as long as the 
 abdomen. But this range is not confined to the larger genera, for sev- 
 eral monotypic genera (Dendrotettix, Phoetaliotes, and Oedaleonotus) dis- 
 play a wide difference between different forms of the single species they 
 possess, in the length of the tegmina, a difference which is also paral- 
 leled or almost paralleled among certain species of the genera Hespero- 
 tettijc, Podisma, Melanoplus, and Paroxya, and particularly of the genus 
 Melanoplus. 
 
 This last genus is of particular interest in this connection, for it is 
 subequally divided between distinctly short-winged and distinctly long- 
 winged forms, which only rarely appear to be closely allied; yet in four 
 of the species, M. dawsoni, M. marginatus, M.fasciatus, and M. extremis 
 species in no way closely related there is a marked dimorphism in 
 respect of the length of the tegmina, the first two being normally pos- 
 sessed of tegmina only slightly longer than the pronotum, the last two 
 of tegmina hardly as long, if as long, as the abdomen, but all occasion- 
 ally equipped with tegmina distinctly surpassing the hind femora. 
 When, however, we compare these fully developed tegmina (Plate I, tigs. 
 a, c, /, i) either with the abbreviated tegmina of the same species, as in 
 If. extremus (Plate I, fig. </), or with those of their nearest macropterous 
 allies, M. gladstoni (Plate I, fig. b), M.paroxyoides (Plate I, fig. fc), and 
 M. borealis (Plate I, fig. d), as in the other species, we can not fail to be 
 struck by the common differences which separate these abnormal macrop- 
 terous tegmina from the normal tegmina of the genus. (See further the 
 tegmina of the type of the genus, M. femur-rubrum, Plate I, tig. /?.). 
 Instead of the regularly tapering form normal to the genus, the added 
 portion, which is largely the extension of the region beyond the post- 
 radial intercalary area, is nearly equal, giving the tegmina a consider- 
 ably greater apical breadth and a consequent openness of neuration, 
 besides a less tapering form. What is further to be noticed is that this 
 apical breadth and openness of neuratiou is also the characteristic of 
 several cases in other genera where there is similar dimorphism in length 
 of tegmina, as in Dendrotettix quercus, Podisma alpina, and Phoetaliotes 
 nebrascensis (Plate I, fig. e). In Podisma the most abbreviated form ot 
 wing is plainly normal, and I am therefore inclined from these examples 
 to regard the abbreviated as the normal form in Dendrotettix, Phoeta- 
 liotes,smd the species of Melanoplus (except, of course, M. femur-rubrum) 
 here illustrated. The same, however, is not the case in Oedaleonotus, 
 where dimorphism of similar degree is found, and it is therefore prob-

 able that the fully equipped form is here the normal, although, so far as 
 we now know, it is much less commonly found than the brachypterous 
 forms. Other instances where there is considerable but not so marked 
 nor perhaps so uniform a difference in win^-length is in Paroxya flori- 
 (lana and perhaps Hesperotettix viridis, in both which genera the length 
 of the tegmina is variable. In these two species the tegmina are not 
 apically broad in the macropterous forms, and differ only in length from 
 the brachypterous forms. 
 
 MtttcrialKj etc. The specimens forming the basis of the present study 
 are in my own cabinet, which contains, often in large series, the greater 
 portion of the species, collected in large part by myself in different 
 sections of the country, but supplemented by specimens secured from 
 the Texan collections of Boll and Belfrage, a large series from Iowa 
 and Illinois obtained by Doctor J. A. Allen, and others from the South- 
 western States and Mexico by Edward Palmer; besides the entire col- 
 lection of Mr. P. E. Uhler, who many years ago generously turned over 
 to me his own private collection, containing among other things many 
 specimens obtained from the early explorers of the West. 
 
 Through the favor of the Assistant Secretary of the Smithsonian 
 Institution, in charge of the United States National Museum, Doctor G. 
 Brown Goode, and the Honorary Curator of Insects in the same insti- 
 tution, Doctor C. V. Eiley, I have had the Museum's entire collection of 
 Melanopli in my hands during this study. The collections of the 
 Museum of Comparative Zoology in Cambridge, Massachusetts, have 
 also been open to me. My neighbors and colleagues, Mr. Samuel Hen- 
 shaw and Mr. A. P. Morse, have also placed all their Melanopli in my 
 hands; and from Professor Lawrence Bruner, of Lincoln, Nebraska, I 
 have received a complete series of all the forms known to him, which has 
 been on the whole the most important aid I have received. Professor 
 Jerome McNeill, who had begun a study of the Melanopli, mainly of the 
 National Museum, not only generously transferred the work to my hands, 
 but gave me free use of his notes and sent me several species otherwise 
 unknown to me. The University of Kansas sent me a series of interest- 
 ing western forms in its museum, Mr. W. S. Blatchley a series of the 
 Indiana species known to him, Professor C. P. Gillette interesting forms 
 from Colorado, and Professor H. B. Weed a few from Mississippi. All 
 of these gentlemen have freely answered many inquiries made of them, 
 and any failing in the present paper must be laid at my door. In this 
 way I have seen the types of nearly all the species described from 
 North America, and while in England Mr. Samuel Henshaw kindly 
 examined for me several of Walker's types at the British Museum. I 
 have been further aided for the European species by Hofrath Brunner 
 von Wattenwyl, Doctor Chr. Aurivillius, and Mons. A. de Bormaus. 
 
 In all, I have examined for the purposes of this paper nearly eight 
 thousand specimens, of which about seven thousand belong to the

 single genus Melanoplus. The sexes are nearly equally divided, the 
 males forming about forty-six per cent of the whole. Thirty genera 
 (eighteen new) and two hundred and seven species (one hundred and 
 fifteen new) are described in the present paper. 
 
 Finally, by the aid of a grant from the ELIZABETH THOMPSON SCI- 
 ENCE FUND I have been able to procure illustrations of the abdominal 
 appendages of every avaiable species. 
 
 A few words should be added regarding certain details of presenta- 
 tion: Instead of giving the range of variation in the measurements of 
 each species, I have selected as far as possible typical average speci- 
 mens, male and female, for the purpose, taking the measurements of all 
 parts from the same individuals. The number of individuals of each 
 species seen is given, and the localities from which they came immedi- 
 ately added, with the name of the collector (when not myself), and 
 when not from my own collection, the source from which I have received 
 them stated (in parentheses); occasionally my own name is there 
 added, when specimens from the same source are also found in my col- 
 lection ; where no parenthesis follows the locality, the specimens referred 
 to are in my collection. 
 
 In describing the abdominal appendages of the males, I have found 
 it convenient to introduce a few new terms. These are: Furcula for 
 the pair of backward-directed apophyses of the last dorsal segment, 
 which overlie, generally in a more or less forked position, the base of 
 the supraanal plate ; infracercal plates for the variously developed but 
 generally inconspicuous paired plates, which underlie in part the cerci, 
 in part the lateral portions of the supraanal plate; and. pallium for the 
 sometimes erectile, membranous pellicle partially closing the open 
 cavity formed of the walls of the subgenital plate, and variously devel- 
 oped in the different genera.

 outer series. Lateral margin of the subgenital plate of the male straight 
 from base outward, at the tip slightly elevated into a minute erect 
 tubercle; cerci simple, conical. 
 
 This genus is very distinct from anything known to me, and I have 
 been in some doubt as to whether it should be placed in Melanopli, 
 especially as in the only male I have seen there were but eight spines 
 on the outer side of the hind tibiae; but Professor L. Bruner informs 
 me that he has an immature male with nine spines, which agrees with 
 what I find in the female, so that this feature must be looked on as 
 variable, as it is in some other genera of Melanopli. 
 
 Although I have placed it at an extreme distance from Aptenopedes, 
 from which it is clearly widely separated in the lack of any basal 
 ampliation of the subgenital plate of the male, it recalls that genus in 
 its general appearance and especially in the triangular vertex of the 
 head; it differs, however, much from it in its subcylindrical slender 
 body and the close approximation of the sternal lobes. 
 
 It is represented by a single species occurring in Florida.

 Body luteo-testaceous, heavily marked with black. Head uniform 
 luteo-testaceous, sometimes feebly infuscated, with a broad black baud 
 behind the eyes, and the lateral faces of the frontal costa above the 
 antennae marked with black; antennae blackish fuscous. Prouotum 
 and body behind it with a broad equal mesial baud of luteo-testaceous, 
 separating two very broad black bauds precisely as in N. fusiform is, 
 only the lower third of the lateral lobes, the inesothoracic episterna and 
 the lower half of the metathoracic episterna luteous. Meso- and rneta- 
 nota with scarcely perceptible very sparse punctuation ; posterior mar-

 Three males, 2 females. Mount Orizaba, Mexico, W. S. Blatchley; the 
 same, 11,500 feet, March (L. Bruner). Originally described from the 
 same mountain as collected by M. Aug. Salle "an pied de la niege." 
 Mr. Blatchley informs me that at the time of his visit the snow line 
 was at 15,000 feet, and adds that he took a single specimen of the species 
 at 13,500 feet, "a very few individuals may have been taken as low as 
 9,000 feet, but the species was common only between 10,000 feet and 
 12,000 feet; above 12,000 feet scarce." 
 
 According to statements in the daily press, 1 Orizaba, which is of 
 volcanic origin, showed signs of a renewal of activity early in March, 
 1895, when hot ashes were ejected, the snow disappeared from the sum- 
 mit and the vegetation of the upper part of the mountain was burned. 
 Possibly this means the extinction of Paradichroplus mexicanus. 
 
 The following description of the living insect, made upon the spot, 
 has been kindly sent me by Mr. Blatchley: Pronotum of male ash 
 gray tinged with yellow, especially along the median line; sides of 
 pronotum with a brownish stripe on upper half, bordered below with

 the back, the sides brown, the sternites yellow; sternites of thorax 
 bluish gray; a whitish bar extends from base of tegmiua diagonally 
 to hind coxae; sides of hind femora brown with two yellowish stripes 
 on upper margin, below light orange; tibiae deep orange; tarsi flesh 
 color. Female tinged with greenish yellow where there is clear yellow 
 in the male; cheeks, whole sternum and lower sides of abdomen blue, 
 especially the sternites of thorax ; lower sides of hind femora and tibiae 
 deep orange. 
 
 Mr. Samuel Henshaw, while recently in London, procured for me at 
 the British Museum a drawing of the genitalia of Walker's Caloptenus 
 med'icanus, described by him as new, showing that it was unquestion- 
 ably the present species. (See Plate II, fig. 4.)

 and the face retreating slightly; eyes very large, moderately promi- 
 nent, about equally so in the* two sexes, broadly ovate in the male, 
 elliptical in the female, much longer than the intraocular portion of the

 The broader cerci, incurved throughout and not abruptly bent inward 
 apical ly, separate this species clearly from R. palmer i. In one view 
 their base may be said to be narrower than the apical portion and so 
 the description of StaPs species would.be applicable to this, but the 
 interval between the mesosterual lobes of the male is here nearly twice 
 as long as broad, while in R.pilosus it is more nearly quadrate. 
 
 2. RHABDOTETTIX PALMERI, new species. 
 (Plate III, fig. 3.) 
 
 Body thinly but not briefly pilose, luteo- testaceous beneath, black or 
 blackish ferruginous (male) or ferrugineo-testaceous (female) above, 
 marked with dull luteous; the darker parts are found in a dorsal stripe 
 from the front of the vertex to the front of the metazona, on the upper 
 half of the lateral lobes of the prouotum, and on the sides of the 
 abdomen. Head luteo-testaceous, more or less deeply infuscated; 
 frontal costa feebly punctate above; antennae luteous or testaceous, 
 apically infuscated. Pronotum with the dark portions mentioned 
 separated by a narrow light stripe, which begins behind the upper 
 part of the eyes and on the head is bright luteous, but in passing over 
 the pronotum, especially iu the female, becomes much duller and is 
 sometimes scarcely distinguishable; in most vivid examples it crosses 
 the pronotum, but even in the male it usually becomes obsolescent on 
 the metazona, which is mostly ferrugineo-testaceous in both sexes, 
 rarely black mesially in the male; the lateral stripe on the pronotum 
 generally margined more or less distinctly with black ; lower portions 
 of lateral lobes luteous or luteo-testaceous, narrowly edged beneath 
 with testaceous; abdomen with a widening dorsal stripe of ferrugineo- 
 testaceous. Fore and middle femora ferruginous, slightly iufuscated 
 apically; hind femora green, ferruginous above, the upper genicular 
 lobe and sometimes the whole gemculation black; hind tibiae green, 
 the spines black-tipped, usually nine but varying from nine to eleven 
 in the outer series. Supraanal plate of male triangular with slightly 
 convex sides, which are slightly elevated and separated by a broad 
 valley from the median tectate portion; the latter is considerably ele 
 vated and carries a deep slender median sulcus more than half the 
 length of the plate; furcula consisting of a pair of broad plates, whose 
 advance beyond the posterior line of the last dorsal segment is scarcely 
 perceptible, each about a quarter the basal width of the supraanal 
 plate; cerci moderately broad, compressed, straight and slightly dirnin 
 ishingin size for about two-thirds their length, then suddenly and con 
 siderably curved inward and bent upward, narrowing more rapidly and

 The antennae of the male are scarcely, so long in this species as in 
 the others; it differs decidedly from E. concinnus in the bent and narrow 
 cerci as well as in the more nearly quadrate interspace between the 
 mesosternal lobes of the male; from E. pilosus, to which it seems more 
 nearly allied and for which I at first mistook it, it differs in the cerci of 
 the male, which do not narrow before the middle, in being a smaller 
 insect, besides having a duller coloring with more contrasted markings, 
 to judge from Stal's description.

 I have not seen this species, and accordingly give Stal's description, 
 englished. The description is mainly a comparative one, the basis of 
 comparison being Aidemona azteca, next which Stal placed it, in the 
 same section of Pezotettix. 
 
 Olivaceous ; legs yellowish olivaceous ; hind tibiae greenish olivaceous, 
 the base and geniculatioii proper of the hind femora black; tegmina 
 rudimentary. Length of male 16 mm. 
 
 Male. Interspace between mesosternal lobes a little longer than 
 broad, with parallel sides, much narrower than the lobes themselves; 
 metasternal lobes subcontiguous ; eyes large, rather convex; apical 
 margin [of the pronotumj gradually and obtusely sinuate, slightly 
 emargmate in the middle, destitute of a lobe; supraanal plate fur- 
 nished with a gradually narrowing sulcus, extending beyond the 
 middle of the plate; cerci gently curved, compressed and rather broad 
 throughout, before the middle slightly narrowed; subgenital plate 
 short, very strongly recurved; abdomen posteriorly tumescent and 
 somewhat recurved. 
 
 Distinguished from Aidemona azteca by the front and prozona less 
 densely punctate, frontal costa obtusely subsulcate, narrower between 
 the antennae, the sides parallel but slightly narrowed at the base, the 
 interspace between the eyes narrower, the disk of the pronotum 
 smooth, abbreviate and truncate anteriorly, the metazona about half 
 as long as the prozona, tegmina rudimentary, widely separated, ellip- 
 tical, extending slightly beyond the median segment, shorter than the 
 pronotum, the abdomen blunter at tip, posteriorly more tumid and 
 recurved, the cerci broader, the last dorsal segment of the abdomen

 with no obtuse apically emarginate lobe [furcula], the hind femora 
 slenderer and longer, prosternal spine conical, and the antennae longer, 
 more than half as long as the body; hind tibiae in the specimen 
 described furnished exteriorly with eight black spines, greenish oliva- 
 ceous at the base. 
 
 A female specimen, in which the dor sum of the body and of the hind 
 femora are ferruginous, with smaller eyes, the interspace between the 
 mesosternal lobes subtransverse and scarcely narrower than the lobes 
 themselves, and metasternal lobes moderately distant, is very probably 
 to be referred to the species described above. In this specimen the 
 antennae are mutilated and the hind tibiae armed exteriorly with nine 
 spines.

 To this I may add that the present species is certainly very close to 
 the others described above under this genus, but seems to be slightly 
 larger than either, and to differ by the cerci of the male to a greater 
 degree than either of these do from each other. It is evidently also of 
 a lighter color, and no mention is made by Stal of a very distinct dark 
 lateral baud, which is characteristic of the other two. 
 
 1O. CYCLOCERCUS, new genus. 
 (nvxho?, circle; nspno^, tail.) 
 
 Body shaped much as in Paraidemona, male and female, rather 
 sparsely and not very briefly pilose. Head not prominent, the vertex 
 moderately arched, scarcely elevated above the pronotum, but the 
 fastigiuin rapidly descending, more or less sulcate especially in the 
 male, much broadened anteriorly; face moderately retreating, the 
 frontal costa generally more or less sulcate and broadening slightly 
 from above downward, generally percurrent ; interval between the eyes 
 narrow (male) or rather narrow (female), generally narrower than the 
 upper part of the frontal costa; eyes moderately prominent, especially 
 in the male, generally much (male) or scarcely (female) longer than the 
 posterior infraocular portion of the genae; antennae much (male) or 
 scarcely if at all (female) longer than the head and pronotum together. 
 Pronotum scarcely (male) or considerably (female) enlarging from in 
 front backward, both front and hind margins truncate, the latter some- 
 times slightly emarginate, the surface transversely convex with feeble 
 or no median carina and no lateral carinae, the disk passing jilmost 
 insensibly into the vertical lateral lobes; prozona about twice as long 
 as the metazona and less closely and less regularly punctate, the trans- 
 verse sulci as in Sinaloa. Prosternal spine erect, blunt, conical; inter- 
 val between mesosterual lobes at least as long as broad in the male, a 
 little transverse in the female, the metasternal lobes attingent or sub- 
 attingent in the male, approximate in the female. Tegmina shorter 
 than the pronotum, lateral, linear. Fore and middle femora distinctly 
 more gibbous in the male than in the female; hind femora rather short

 and stout, the outer margin of the hind tibiae with nine or ten spines. 
 Extremity of abdomen bluntly rounded (whence the generic name), the 
 lateral margins of the subgenital plate straight from the very base, in 
 no way angulate on meeting apically, but protruding beyond the apex 
 of the supraanal plate by more than half the length of the latter; cerci 
 conical, acuminate, sometimes with an inferior median tooth; furcula 
 wholly wanting. 
 
 Three species occur in northern* Mexico and southern Texas. 
 
 C. bintrif/ata may be taken as the type. C. valya is somewhat aber- 
 rant, and should perhaps be separated generically.

 It is possible that the male, which comes from Yeuis Mecas, may be 
 distinct from the females, which come from all the localities; in that 
 case the name should be retained for the male as the most characteristic 
 form.

 (Plate III, fig. 6.) 
 
 Brownish testaceous with blackish and dull luteous markings. Head 
 dull luteo-testacoous, the whole summit of the head to below the middle 
 of the eyes posteriorly blackish, with a narrow and somewhat obscure 
 luteous stripe on either side, following the sides of the entire fastigium 
 around the eyes to the middle and then passing backward, continuing 
 across the prozona on the upper margin of the lateral lobes; fastigium 
 feebly sulcate between the eyes, which are separated by a narrow space, 
 much narrower than the rather broad and subequal frontal costa; this 
 becomes obsolescent below and is shallowly sulcate in the middle and 
 sparsely and feebly punctate throughout, like the rest of the face and 
 the genae ; antennae luteo-testaceous. Pronotuin with a broad blackish 
 fuscous dorsal stripe, crossing the whole prozona between the luteous 
 stripes mentioned, coarsely and feebly rugoso-punctate ; metazona finely 
 and closely rugoso-punctate, rufo-testaceous ; lateral lobes pallid lute- 
 ous below, crossed above by a very broad mixed luteo-castaneous and 
 blackish band, greatly broadening and weakening on the metazona, 
 where it becomes rufo-testaceous; episterna pale greenish luteous; 
 epiniera subpiceous. Interspace between mesosternal lobes of male 
 subquadrate. Tegmina dark fuscous with luteous veins, about as long

 margin and metazoua, distinctly enlarging posteriorly in the female, 
 both front and hind margin truncate, the latter feebly emarginate, with 
 slight percurreut median carina and no lateral carinae, the lateral lobes 
 vertical ; prozoua almost twice as long as, and less feebly punctate than,

 by a sinuous or broadly W-shaped sulcus, both tolerably distinct. 
 Prosternal spine erect, conical, bluntly pointed; interval between meso- 
 sternal lobes feebly transverse in both sexes, the nietasternal lobes not 
 very close. Tegmiua brief, lobiform, lateral. Fore and middle femora

 feeble signs of delicate puncta, no more abundant on the frontal costa 
 than elsewhere; antennae flavo-testaceous, growing iufuscated apically. 
 Pronotum with the metazona transversely and snbrugosely punctate, 
 especially in the male and on the lateral lobes, simply punctate on the 
 disk in the female, transversely striate in the region of the lateral

 (rcapa, beside; Aiclemona, a genus of Melanopli.) 
 Paraidemona BRUNNEK (pars), Re"v. Syst. Orth. (1893), p. 145. 
 
 Body compact, not slender, subcylindrical, a little compressed, slightly 
 enlarged at the metathorax, especially in the female, the abdomen of 
 the male feebly clepsydral, the apex tumescent and rounded, and some- 
 what recurved. Head not prominent, the vertex well rounded, the 
 eyes separated narrowly in the male, not widely in the female, rather 
 prominent, particularly in the male, and large, much larger than the 
 infraocular portion of the genae, subangulate above in the female; 
 antennae very much longer than head and pronotum together, especially 
 in the male. Pronotum truncate at both extremities, enlarging very 
 slightly posteriorly, more in the female than the male, with slight, per- 
 current, median carina, no lateral cariuae; prozona twice as long as 
 the metazona, both equally and somewhat similarly punctato rugulose, 
 the transverse sulci of the prozona lightly impressed, one of them 
 dividing the prozona in equal halves and percurrent. Prosternal spine 
 moderate, blunt, conical, erect; interval between mesosternal lobes of 
 male longer, sometimes much longer, than broad; of female (where 
 known) a little longer than broad; metasternal lobes narrowly attin-

 Interspace between eyes as broad as (male) or rather broader than 
 (female) the first antenna! joint; frontal costa moderate, equal, flat 
 above, sulcate at, below, and to some extent a short distance above, 
 the ocellus. Pronotum expanding a very little posteriorly, mostly on 
 the posterior half, the front and hind margins truncate, the latter some- 
 times almost imperceptibly emarginate in the middle, especially in the 
 male, the lateral carinae wholly wanting; the whole pronotum is equally 
 subrugoso-punctate throughout, unless it be that the disk is coarser 
 than the deflected lobes; meso- and metanota, and the basal segments 
 of the abdomen similarly but more obscurely punctured. The general 
 color is a greenish yellow more or less tinged with brown, brighter in the 
 male than in the female, and marked with blackish fuscous; the darker 
 markings consist, principally, of a dorsal stripe, which either extends 
 over the pronotum as a broad equal band, often fainter in the middle, 
 with a triangular extension on the head, and sometimes a narrowing 
 infnscatioii on the meso- and metanota (male), or forms an obovate 
 patch along the middle of the anterior lobe of the prothorax, with the 
 same triangular extension on the head, and reappears sometimes on the 
 meso and metathorax, and always on the abdominal joints, as a series 
 of obliquely-descending, triangular, lateral patches, separated from one 
 another by a yellowish median line (female) ; also of a broad lateral band, 
 which extends from behind the eye backward, either to the hinder edge 
 of the prothorax, its upper margin straight, its lower arcuate (male), or 
 across the prozona only, occasionally in an obscure manner across the 
 metazona also, both margins arcuate (female); beyond this the lateral 
 band extends over the remainder of the thorax and over the abdomen, 
 often broken into spots on the latter, and always enlivened on the for- 
 mer by an oblique yellowish line, which crosses it on the metathoracic 
 episterna. The face partakes of the color of the under surface, as do the 
 bases of the antennae; beyond, the antennae become slightly rufous; 
 just behind its narrowest point the vertex has a transverse blackish 
 line, Hind femora greenish yellow, the lower portion of their outer 
 face more or less embrowned, deepening frequently into black, which 
 occasionally covers the whole; hind tibiae pale green, the spines black 
 tipped. Subgenital plate of male twice as broad as long, tumid, the 
 upper edge a little and angularly produced in the middle; supraanal

 plate nearly quadrate, tapering very slightly, the outer angles slightly 
 produced, and the posterior edge with a median, triangular, pointed 
 extension, a third as wide as the extremity of the plate and longer 
 than broad; furcula consisting of a pair of attingent, depressed, rather 
 stout, scarcely tapering, blunt-tipped fingers, fully half as long as the 
 suprannal plate and slightly upturned at the tip ; anal cerci very simple, 
 being slight conical projections^ tapering mostly in their basal half, the 
 tip blunt, the whole not so long as the disk of the supraanal plate, 
 omitting its apical extension.

 2. PARAIDEMONA MIMICA, new species. 
 (Plate III, fig. 10.) 
 
 Yellowish testaceous, heavily banded with black, especially on the 
 sides, and more markedly in the male than the female. Head with 
 the interspace between the eyes very narrow, especially in the male, 
 the fastigium between them sulcate, narrowly in the male, the sulcation 
 continuing so as to be subcontinuous with that of the frontal costa, 
 which is sulcate in its whole extent, equal, and broader than the inter- 
 space between the eyes. Prouotum punctate as in P. punctata, and as 
 there a glabrous spot free of punctuation occurs on the prozoua at the 
 summit of the lateral lobes. A black stripe, sometimes wanting or 
 feebly fuscous in the female, begins at some point on the fastigium and 
 continues backward, broadening on the head so as to include nearly 
 the entire vertex, and crosses the pronotuni as a broad mediodorsal 
 band, as broad as the length of the metazona, or in the female even 
 broader; it is sometimes obscure or wholly obsolete in the female, while 
 in the male it is always distinct, at least on the prozona, and generally 
 continues, though narrowed, over the rneso- and metanota. The lat- 
 eral band, generally rnfo-piceous, is still broader and is sharply defined 
 above and below, often uninterrupted on the metazona in the female, 
 where it widens so as to include behind the whole of the thoracic pleura 
 (excepting the episterna) and the sides of the first four abdominal seg- 
 ments; above it is more or less distinctly accompanied in the female by 
 a testaceous stripe. The dorsum of the abdomen of the female lacks 
 the double series of oblique lateral dashes found in P. punctata, or has 
 them very feebly marked. Hind femora yellowish testaceous, the outer 
 face growing darker below, giving there a broken irregular blackish 
 stripe ; hind tibiae glaucous, the pallid spines black tipped. Supraaual

 plate of male triangular, with the lateral margins slightly convex in

 This species resembles P. punctata to such a degree as with difficulty 
 to be distinguished from it, except by the abdominal appendages of the 
 male, which are remarkably distinct. There is no sign in the female of 
 the dark mediodorsal fusiform patch on the prouotuni, and the coloring 
 of the female in both species is very variable. 
 
 There are two other forms of Paraidemona known to me, which I 
 deem probably distinct from either of the above, but being known 
 only by the female, I only allude to them. Both have relatively heavy 
 hind femora. 
 
 One is almost wholly olivaceous, the abdominal carina marked with 
 yellow, and with yellow shades upon the sides of the dorsum of the 
 thorax; it comes from Carrizo Springs, Texas (U.S.N.M.). 
 
 The other is almost wholly yellowish testaceous, with no dorsal stripe 
 and relatively feeble and fleeting lateral stripes; it comes from Dallas, 
 Texas (U.S.X.M.), and Venis Mecas, San Luis Potosi, Mexico, January 
 6, E. Palmer.

 Aidemona BRUNXER, R6v. Syst. Orth., 1893, p. 145. 
 
 Body compact, moderately slender, parallel sided but enlarged at the 
 mesothorax. Head not prominent, the vertex well rounded, rising 
 above the level of the prouotum, the space between the eyes narrow 
 but not very narrow, the face broadly rounded and a little retreating; 
 frontal costa a little prominent above, broad, much broader than the 
 interspace between the eyes, plane, percurrent, subequal, and heavily 
 punctate; eyes moderately prominent but little more so In the male 
 than in the female, rather large, broad ovate, much larger than the 
 subocular portion of the genae; antennae slender, rather shorter than 
 the head and pronotum together. Pronotum scarcely enlarging poste- 
 riorly, transversely quadrate, the dorsum plane or very feebly convex, 
 with the lateral lobes set sharply at right angles to it, but otherwise 
 with no raised lateral cariuae, a feeble median carina on metazona only,

 the front margiu truncate, the hind margin subrectangulate; prozona 
 and metazona of subequal length, the sulcus separating them distinct 
 but not deep, suddenly augulatc in the middle by the emargination of 
 the prozona, tbe posterior sulcus of the prozona arcuate or angulate so 
 as to approach it in the middle, the middle sulcus subparallel to this 
 but more nearly transverse and crossing the middle of the prozona, the 
 front of the prozona in no w$iy elevated to receive the head. Pro- 
 sternal spine quadrate, appressed," broadly truncate; interspace between 
 mesosternal lobes subquadrate, a little longer than broad in the male, 
 the reverse in the female, the metasternal lobes attingent over some 
 space (male) or approximate (female). Tegmiua and wings fully devel- 
 oped, the former with scarcely any ampliation of the costa near the 
 base. Fore and middle femora but little more gibbous in the male 
 than m the female; hind femora not very long, the hind tibiae with ten 
 spines on the outer side. Margin of subgenital plate of male straight 
 from the base, which is not ampliate, a little elevated at the apex; 
 cerci styliform, about as long as the supraanal plate, the furcula nearly 
 obsolete. 
 The genus is confined so far as known to Mexico and Central America.

 Brownish fuscous above, sometimes deepening to blackish fuscous, 
 especially on the upper half of the lateral lobes of the pronotum, testa- 
 ceous below, often deeply infuscated. Head mostly testaceous, heavily 
 punctate throughout excepting on the vertex, where the puncta are 
 obscure and subdued, and where the color is dark; fastigiuin with more 
 or less elevated but rounded lateral walls; frontal costa slightly 
 widened just above the ocellus; antennae testaceous, more or less 
 infuscated, especially toward apex. Pronotum heavily and almost 
 equally punctate throughout, both on dorsum and lateral lobes, but less 
 crowded on the posterior half of the lateral lobes of the prozona, and 
 with a small, free, glabrous patch above on either half of the prozona; 
 lower half of the lateral lobes testaceous, in greater or less contrast to 
 the blackish upper half, the darker portion widening on the metazona; 
 but while this feature is sometimes very marked, in specimens in which 
 the testaceous under surface becomes flavous, it is sometimes scarcely 
 to be detected, so infuscated may the lower half become. Tegmina 
 far surpassing the abdomen, rather slender, well rounded apically, 
 griseous from a profuse and rather minute fuscous flecking on a semi- 
 pellucid base, the flecking more or less confluent in the basal third;

 wings pellucid, feebly infuscated apically, the veins and cross veins 
 blackish fuscous. Hind femora very variable, the outer face varying 
 from olivaceo-testaceous with fuscous incisures to dark almost blackish 
 fuscous, the most distinctly marked specimens with the base broadly 
 and obliquely yellowish testaceous, and a middle oblique band of no 
 great width of the same color; inner side red; hind tibiae obscure 
 glaucous, becoming luteous toward the base, rather densely pilose, the 
 spines black-tipped. Supraanal plate of male triangular, rather small, 
 tectate especially apically, with a narrow basal median sulcus, bounded 
 by high and heavy walls, which do not extend over half the plate; 
 furcula composed of a pair of very small, rounded, attingent lobes, 
 barely projecting beyond the edge of the last dorsal segment; cerci 
 about as long as the supraanal plate, slender, tapering throughout 
 but slightly more in the basal than the apical half, feebly compressed, 
 acuminate, feebly incurved in the apical half; infracercal plates brief, 
 concealed.

 Body slender, compressed, very thinly pilose. Head not prominent, 
 the summit gently arched, the fastigiuni descending with moderate 
 rapidity, the face- re treating considerably; interspace between the eyes 
 broad, the fastigium scarcely sulcate, the frontal costa rather narrow, 
 not nearly so broad as the space between the eyes, sulcate, percurrent, 
 and subequal; eyes moderate in size, not very prominent, similar in the 
 two sexes, about half as long again as broad, and distinctly longer than 
 the anterior infraocular portion of the genae; antennae moderately 
 stout, somewhat longer (male) or a little shorter (female) than the head 
 and pronotum together. Pronotum subequal, even in the female, very 
 feebly and gradually enlarging in passing backward, with a distinct 
 percurrent median carina, the disk very broadly subtectate, passing by 
 a rounded angle hardly forming a lateral carina into the vertical lateral

 lobes, the front margin subtruncate, the hind margin very obtusely 
 angulate, the very coarsely, feebly, and sparsely punctate prozona half 
 as long again as the finely and suddenly punctate metazona, its poste- 
 rior margin faintly angularly emarginate, the transverse sulci feeble, 
 one dividing it into two equal halves and straight, the other a third 
 the way behind it to the metazona and sinuate. Prosternal spine erect, 
 moderately slender, conical; Interspace between inesosternal lobes 
 more than twice as long (male), or nearly half as long again (female) as 
 its middle breadth, the shape being strongly clepsydral from the con- 
 vexity of the inner margin of the lobes, the metasternal lobes subat- 
 tingent, especially in the male. Tegmiua abbreviate, acuminate, attin- 
 gent or overlapping, about as long as the pronotum. Fore and middle 
 femora slightly tumid in the male; hind femora slender, somewhat 
 compressed, the lower genicular lobe not free from markings, the hind 
 tibiae with nine to ten spines in the outer series. Abdomen of male 
 not clavate nor curved upward apically, the lateral margins of the sub- 
 genital plate straight from the very base, acutaugulate at tip, with a 
 slight, blunt, apical tubercle; cerci very slender and simple; furcula 
 consisting of a pair of slight cylindrical slender fingers, subparallel or 
 more or less crossing one another, perhaps parallel in life. 
 
 This genus was established by Brunner upon three species, one of 
 which must be referred to Hesperotettix, since the lateral margins of 
 the subgenital plate are clearly ampliate at the base; while another has 
 here been placed in a near and neighboring genus, Campy lacanthaj 
 leaving H. alba as the type and at present the only known member of 
 the genus. It is found in our Western States only, east of the Rocky 
 Mountains, and from Nebraska southward.

 The species was originally described from Glencoe, Dodge County, 
 Nebraska. It has since been reported from Manitoba, Minnesota, 
 Dakota, Montana, and from Fort McKinney, Johnson County, Wyo- 
 ming, and Kansas by Bruner, from Iowa by Osborn, and Colorado by 
 Thomas. "Here in Nebraska," says Bruner, "it is one of our common- 
 est species, when one knows where to look for it." It feeds, according 
 to the same writer, on what is called in the West " white sage," Arte- 
 misia ludoviciana, with which its colors closely correspond.

 ately retreating; interspace between the eyes rather broad (male) or 
 broad (female), the fastigiuin feebly if at all silicate, the frontal costa 
 distinctly broadest between the antennae, where it is nearly as wide as 
 (male) or still much narrower than (female) the interspace between the 
 eyes, percurrent, sulcate at least below the ocellus; eyes not very 
 prominent nor very large, longer in proportion to breadth in the female 
 than in the male, and yet in the female hardly, in the male distinctly, 
 longer than the anterior infraocular portion of the genae; antennae 
 rather coarse, more than half as long as the body in the male, distinctly 
 longer than head and pronotuin together in the female. Pronotum sub- 
 equal (male) or distinctly and very gradually broadening posteriorly 
 (female), with a rather slight median carina, sometimes interrupted 
 between the sulci, the disk very broadly subtectate, passing by a rounded 
 angle, without forming lateral cariuae, into the vertical (female) or sub- 
 vertical (male) lateral lobes, the front margin subtiuncate, in no way 
 flaring, the hind margin obtusely angulate, the impunctate or very fee- 
 bly rugulose prozona nearly or quite half as long again as the punctate 
 or distinctly rugulose inetazoua, its transverse sulci moderately dis- 
 tinct, that in the middle straight, and followed a third of the way to 
 the metazona by a similar but arcuate sulcus. Prosternal spine blunt 
 conico- cylindrical, more or less retrorse; interspace between mesoster- 
 nal lobes nearly twice as long (male) or half as long again (female) as 
 broad, the inner margins of the lobes nearly straight; metasternal 
 lobes attiugent (male) or subattingeut (female). Tegmina abbreviated, 
 generally but not always a little longer than the pronotuin, rounded or 
 subacuminate at tip, their inner margins overlapping or separated. 
 Fore and middle femora distinctly gibbous in the male; hind femora 
 variable, as also the coloring of the inferior genicular lobe; hind tibiae 
 with nine to ten, generally nine, spines in the outer series. Abdomen 
 of male very feebly clavate, very feebly upturned, the lateral margins 
 of the subgenital plate not ampliate at the base, the apex bluntly 
 angulate at tip, with a distinct but not very large tubercle, extending 
 beyond the inner side of the apical margin ; furcula consisting of a pair 
 of slight, rounded, feebly projecting lobes. 
 
 This genus is closely allied to Hypocklora, but is composed of gener- 
 ally stouter forms, in which the antennae are longer, the pronotuin is 
 usually rugulose rather than punctate, and the males of which have 
 more tumid anterior femora, besides the differences pointed out in our 
 table of genera. 
 
 C. acutipennis may be taken as the type. 
 
 The genus occurs only in the West, where it ranges east of the Rocky 
 Mountains from Nebraska to Texas, and occurs again in Durango, 
 Mexico.

 fusco-olivaceous, above broadly infuscated along the middle line and 
 with a narrow piceous postocular stripe, bordered by flavous; vertex 
 feebly tumid, not rising above the level of the pronotuin, the interspace 
 between the eyes fully half as broad again as the first antennal joint; 
 fastigium almost twice as broad anteriorly as posteriorly, little decli- 
 vent, broadly and shallowly sulcate; frontal costa distinctly percur- 
 rent, equal below the ocellus, distinctly broader above it, so as to be as 
 broad there as the interspace between the eyes, the lateral borders ele- 
 vated throughout but rounded and not acute, densely punctate through- 
 out; lateral carinae of face prominent; eyes large, very prominent, 
 nearly half as long again as the infraocular portion of the genae;

 the lateral lobes with a not very broad, percurreut, glistening, blackish 
 fuscous, postocular stripe, directly beneath which the lateral lobes are 
 more brightly colored than below; disk broadly convex, passing into 
 the vertical lateral lobes almost insensibly, except on the anterior sec- 
 tion of the prozona, where there are distinct lateral cariuae, which are 
 separated from each other by only about three- fourths the entire width 
 of the prozona; median carina sharp, percurrent, equal, but on the 
 metazona diminishing posteriorly; front margin truncate, hind margin 
 bluntly obtusangulate; prozona distinctly longitudinal, sparsely punc-

 base of the geuiculation, and $ fuscous upper edging to the genicular 
 arc; hind tibiae very pale red or pink, the spines pallid on the basal, 
 black on the apical half, 12 in number in the outer series. Extremity 
 of male abdomen feebly clavate, scarcely recurved, the supraaual plate 
 triangular, tectate, rising to a pair of high but rounded converging 
 ridges, inclosing between them the deep triangular sulcus, which crosses 
 the basal half of the plate; furcula consisting of a pair of stout and 
 coarse, subparallel, rather distant, subequal, blunt projections, a little 
 longer than broad and than the last dorsal segment; cerci slender, deli- 
 cate, conical, straight, finely acuminate, about as long as the supraanal 
 plate; subgenital plate rather small, considerably longer than broad, 
 equal, terminating in a backward-directed, bluntly rounded tubercle, 
 seated on the middle of the apical portion of the plate, the apical and 
 lateral margins in the same plane, the former well rounded, entire.

 Body almost parallel-sided, very little enlarged at the metathorax, 
 more or less but not greatly compressed, more so in the male than in 
 the female. Head not very prominent; vertex usually very narrow 
 between the eyes, with a slight depression or sulcation between; 
 fastigiuin broadening in front of it, declivent, with a median depression 
 or longitudinal sulcatiou, sometimes distinct, sometimes obscure, the 
 sides rounded; front straight, somewhat oblique, the frontal costa 
 equal, only slightly contracted at the extreme summit, generally as 
 broad as if not broader than the interval between the eyes, sulcate 
 throughout; antennae slightly (female) or considerably (male) longer 
 than the head and pronotuin together; eyes slightly prominent, a little 
 more so in the male than in the female, rather long oval, much longer 
 than the infraocular portion of the geuae. Pronotuin long and slender, 
 the dorsum fully half as long again as broad, the prozona the longer, 
 sometimes half as long again as the metazona, with less distinction in 
 surface and sculpture between them than common, alike broadly tecti- 
 form, the median cariua slight but alike or nearly alike in both, the 
 descending lateral lobes separated by no angle or ruga; posterior mar- 
 gin very obtusely angulate, the angle rounded, the border delicately 
 margined. Prosterual spine rather long, bluntly conical; meso- and

 metastetliia together much longer than broad; interspace between 
 mesosternal lobes generally twice as long as broad in the male, almost 
 equally narrow or subquadrate in the female, the metasternal lobes 
 subattingent in both sexes. Tegmina and wings always present, gen- 
 erally fully developed or a little abbreviate, but sometimes lobate. 
 Fore and middle femora of male tumid; hind femora long and slender, 
 somewhat compressed, generally surpassing the abdomen, the superior 
 carina slight, unarmed; hind tibiae feebly ampliate apically, with 
 spines of similar length on the two sides; first joint of hind tarsi 
 scarcely longer than the third, the second small, with a large inferior 
 apical lobe; aroliuin rather large, nearly twice as long as broad. Sub- 
 genital plate of male furnished with a prominent, subapical, more or 
 less conical tubercle, the lateral margins of the plate suddenly ampliate 
 at base; furcula always distinctly present as a pair of projecting lobes; 
 last abdominal segment of female not abbreviate, the ovipositor nor- 
 mally exserted. 
 
 The type is H. festivus Scudder, a species mistaken for H. viridis 
 Thomas at the time the genus was described. 
 
 This genus is closely related to Hypoclilora and Campylacantha, but 
 is separated from them by the basal ampliation of the margins of the 
 subgenital plate of the male. One of the species indeed (the most 
 aberrant one) was originally placed by Brunuer in Hypoclilora. The 
 genus is still more closely allied to Aeoloplus, from, which it is separable 
 by the form of the prouotum and the slenderness of the body. 
 
 It is found across the United States, but only a single species is 
 known east of the Great Plains, and that one has only been found on 
 or near the Atlantic border. It is generally characteristic of the West. 
 
 Many of the species are very closely allied and have hitherto been 
 confounded by all observers. A large amount of material now enables 
 rne to distinguish them and to find characters which will rarely fail of 
 tolerably certain separation.

 Head varying from olivaceous to ochraceous, sparsely and rather 
 coarsely punctate with fuscous, the costae, front, and inferior margins 
 of the genae more or less pallid, an infraocular black bar and infra- 
 antennal black band, the clypeal incisures black ; fastigium more or less 
 infuscated or blackish, and the vertex with a longitudinal black stripe, 
 broadening posteriorly and there sometimes inclosing a pallid thread; 
 sides of the head behind the eye more or less streaked longitudinally 
 with blackish; antennae warm testaceous, with a greenish tinge near 
 base. Pronotum of the same ground color as the head, but the dorsum 
 often with more or less of a testaceous or subferruginous tint, the sulci 
 narrowly marked in black, a moderately broad mediodorsal bright or 
 dull white stripe rather narrowly margined, sometimes with the excep- 
 tion of the metazona, with black or fuscous; lateral lobes much varie- 
 gated on the prozona by an irregular assortment of brief, longitudinal, 
 black, rarely dark-green bars, sometimes more or less connected to form 
 a gently oblique moderately broad belt. Pleura and tegraina as in 
 H.festivus, and the femora similar, but the hind femora almost always 
 furnished with a moderately broad pregenicular salmon colored com-

 the basal U-shaped elevated ridge a broad deep sulcus, on which is 
 further impressed a slight median longitudinal sulcus from the extrem- 
 ity of the basal ridge; furcula consisting of a pair of slight subtriau- 
 gular projections overlying the two bases of the basal ridge; cerci sim-

 The species was originally described from Colorado, Wyoming, and 
 Kansas, and has since been reported from [New Jersey] (Uhler), [Min- 
 nesota] and Iowa (Bruner), Nebraska (Thomas, Bruuer), Kansas and 
 Colorado (Bruner), Beaver Brook and the Grand Canyon of the Arkan- 
 sas (Uhler); Texas [and Mexico] (Uhler); [Utah] (Bruner), and San 
 Joaquin Valley, California (Coquillet). Localities which are in doubt 
 or in error are placed in brackets. 
 
 This species closely resembles H. festivus, but while generally of a 
 little larger size is distinguished from it by the black-marked sulci of 
 the pronoturn, the generally but not invariably greater irregularity of 
 the markings of the lateral lobes of the pronotum, the red aimulation 
 of the hind femora (though this will probably be found in some individ- 
 uals of H.festimis) and the ground color of the head and pronotum, as 
 well as in slight differences in the abdominal appendages of the male. 
 The eyes are slightly more elongate in H. festivus than in the present 
 species, at least in the female. 
 
 It is wholly uncertain to what species belongs the reference by 
 Thomas 1 to an insect with tegmina only one-third the length of the 
 abdomen, taken in northern New Mexico or Colorado. I have placed 
 it here with a query. 
 
 I possess a couple of females, collected by II. Rid g way in Ruby

 Valley, Nevada, but preserved after long immersion in spirits, which, 
 until fresh specimens are obtained for study, I regard as belonging to 
 this species. They are, however, remarkable for the brevity of the 
 tcginina, which are only as long as the pronotum, and the species has 
 not been otherwise recorded from this region. They seem to represent 
 a short-winged form of this species, their tegmina overlapping like the 
 normal form and not lobate, as in the strictly brachypterous species of 
 this genus. 
 
 2. HESPEROTETTIX MERIDIONALIS, new species. 
 (Plate IV, fig. 9.) 
 
 This species differs but little from H. festivu-s, but has even more 
 strikingly contrasted colors, the green of which is deeper and of a 
 bluer tint and the femora are stouter. The face is yellow with a slight 
 greenish tint, coarsely and distinctly punctate with blackish brown; 
 the intercostal interspace below the antennae is heavily infuscated 
 and the usual short bar below the eyes is present; vertex yellow, the 
 fastigiuin heavily infuscated and behind it a widening blackish stripe, 
 posteriorly inclosing a median yellow thread; antennae fuscous, the 
 joints feebly and narrowly annulate with pale ferruginous. Pronotum 
 yellow, more or less olivaceous, and 011 the inetazona often heavily suf- 
 fused with bright ferruginous, all the transverse sulci and particularly 
 that close to the front margin heavily marked in black, which cuts the 
 heavy black-bordered mediodorsal yellow stripe; upper portion of the 
 lateral lobes more or less heavily marked with black on the prozona; 
 pleural sutures heavily marked in black. Tegmina of about the length 
 of the abdomen, bluish green, the discoidal and posterior ulnar veins 
 with a narrow pallid yellow stripe. Fore and middle femora dull ferru- 
 ginous; hind femora with the outer face dull greenish luteous, the 
 superior carina heavily necked and punctate with fuscous, and a faint, 
 broad, dull coral red, pregenicular annulation; hind tibiae greenish 
 blue, the spines white with black tips, the tarsi more or less testaceous. 
 Supraanal plate of male much as in H. festivus, the furcula consisting 
 of a pair of minute but boldly projecting rounded lobes, separated by 
 twice their own width; cerci slightly compressed, subconical, tapering 
 much more rapidly in the proximal than in the distal half, the latter 
 being nearly equal, the tip rounded but slightly produced and gently 
 incurved, the whole scarcely so long as the supraanal plate; infracercal 
 plates inconspicuous, apically tapering, almost as long as the supraanal 
 plate.

 Zoology which may belong here (as the cerci indicate), but the tegmina 
 are longer than in the specimens described above and the whole appear- 
 ance and the proportions are those of H.festirus. 
 
 Besides the colorational features which distinguish this species from 
 H. viridis, the body is relatively stouter, the antennae coarser and 
 shorter in proportion to the prouotum, the latter is more acutely angu- 
 late behind (though the difference is but slight), the hind femora are 
 shorter and stouter, and the tegmina and wings relatively shorter.

 Face varying from green-yellow to pallid yellow, more or less deeply 
 infuscated in the intercostal space below the antennae, the frontal costa 
 sulcate throughout excepting above, and faintly and distantly punctate 
 with fuscous on the margins; genae pallid or greenish pallid except for 
 a short, slender, oblique, blackish stripe below the eye. Summit of 
 head and dorsum of pronotum buff, greenish buff", rarely green, or oliva- 
 ceous, with a median, black-margined, white or pallid stripe, the stripe 
 reduced to a thread on the head, the black edging remaining; on the 
 sides, above the middle, is a more or less irregular black stripe, more 
 interrupted or broken in the female than in the male, extending from 
 behind the eyes, where it is reduced to parallel longitudinal streaks, to 
 the hinder edge of the prozona, bordered broadly below and above with 
 pallid, above forming a stripe which begins narrowly along the upper 
 edge of the eyes and continues also across the metazona, occupying 
 the position of lateral carinae; excepting for stripes at the median 
 and lateral carinae, the metazona is uniformly buff or rarely green 
 and is very shallowly punctate ; both meso- and metapleura with an 
 oblique, fusiform, pallid stripe, margined more broadly in some places 
 than in others with black. Tegmina of about the length of the abdo- 
 men, rather dark bluish green, the anal area more or less deeply tinged 
 with buff, the discoidal and posterior ulnar veins white, the veinlets 
 impinging on the apical margin distinctly blackish. Fore and middle 
 femora buff, inclining to ferruginous; hind femora buff, but purplish on 
 the outer face and more or less iufuscated, the geniculation with a 
 blackish crescent on the outer and inner sides; hind tibiae bluish green, 
 becoming more or less pallid or testaceous distally, the spines white 
 with black tips, the tarsi testaceous or greenish testaceous. Snpraanal 
 plate of male triangular, of about equal length and breadth, broadly 
 rounded apically, with straight and slightly upturned margins, the sur- 
 face with a pair of converging stout elevated ridges, forming a basal 
 triangular pit between them, and in the distal half of the plate beyond 
 the united ridges a slight median sulcus; furcula consisting of a pair

 of minute rounded lobes, separated by about their own width; cerci 
 simple, subeouical, tapering a very little, more rapidly in the proximal 
 than in distal half, subacutely pointed, as long as the supraanal plate 
 and feebly incurved; infracercal plates not very broad, as long as the 
 supraanal plate, completely concealed by the recumbent cerci.

 The species has previously been reported (under another name) from 
 Lake Point, Salt Lake and Salt Lake Valley (Scudder), Mount Nebo 
 and Spring Lake, Utah (Thomas), and Utah (Bruner). 
 
 The contrasts of colorings in this species render it a more variegated 
 insect than any of the other species of the genus, particularly when the 
 buft' colors are deepest and bring out the black and white with greatest 
 vividness.

 Of the long-winged forms, this species most resembles H. festivus, 
 but is easily distinguished from it, apart from the great difference in 
 the tegmina.

 Head pea green, fusco-puuctate in front, with a short blackish stripe 
 below the eyes, behind the pallid callosity; streaks of dark green pass 
 backward from the eye, and the vertex has a slender, mediodorsal fus- 
 cous stripe, narrowing anteriorly and ending at the base of the fastig- 
 iuin in a round blackish spot; antennae pale ferruginous, slightly 
 iufuscated apically. Pronotum shaped as in H. pratensis, pea green, 
 with a moderately broad, bright ferruginous, obscurely fuscous, mar- 
 gined, mediodorsal stripe, generally broader in the female than in the 
 male; and above the middle of the lateral lobes, but not reaching the 
 front margin nor passing beyond the prozoua, a blackish fuscous bar, 
 sharply delimited below, fading out above, bordered beneath and some- 
 times interrupted posteriorly above with pallid ; sides of the body green 
 except that the metapleura have an oblique pallid stripe, bordered on 
 the upper posterior and lower anterior sides with black. Tegmina con- 
 siderably shorter than the abdomen in both sexes, but particularly in 
 the female, the anal area and a little more than that ferruginous, its upper 
 limit sometimes infuscated, the remainder pea green. Femora almost 
 precisely as in H. pratensis; hind tibiae varying from pea green to pale 
 bluish green, the spines pale on basal, black on apical half; hind tarsi 
 coucolorous with tibiae or sometimes a little yellower. Supraaual plate 
 of male triangular, with straight sides and rounded subacute apex, 
 about as long as broad, with a broad and rather high tectate ridge 
 parallel to the margins, inclosing a deep, basally broad, triangular sul- 
 cus; furcula consisting of a pair of slightly projecting, moderate sized,

 Ten males, 10 females. Wellesley, Norfolk County, Massachusetts, 
 July IG-August 1 (A. P. Morse); New Jersey (U.S.N.M. [Xo. 711]); 
 Georgia, Morrison . 
 
 This species has been previously recorded only from New Jersey 
 (Thomas, Uhler), where Uhler says it is "not uncommon in the cran- 
 berry fields of Atlantic County; 77 and from Wellesley, Massachusetts, 
 by Morse, who tells me that his specimens were taken in a very 
 restricted locality, "a steep gravelly hillside, forming the terminal por- 
 tion of a part of the gravel-plain formation of Wellesley," where they 
 were captured u by sweeping vigorously the short-tufted growth of 
 bunch grass, Andropogon scoparius, which with other wild grasses and 
 running blackberry vines sparsely clothed the gravelly soil." All his 
 specimens were taken between mid July and mid August. Since writ- 
 ing me this, Mr. Morse has found another locality near the previous, 
 where on July 10 he took both sexes mature and nymphs ; the surround- 
 ings were similar. 
 
 This species is very closely allied to H. pratensis, but differs from it 
 in its shorter tegmina and wings, the more regularly conical cerci of 
 the male, the slightly different form of the supraaual plate and the 
 markings ; it is also of a smaller size.

 Head yellowish green, sparsely punctate with fuscous in front, the 
 lower portion of the face more or less obscured with purplish, a short 
 fuscous stripe depending from the eye, in front of which the callosity is 
 livid; vertex with a more or less distinct, rather narrow, fuscous or 
 blackish stripe, narrowing anteriorly, and ordinarily with a median 
 thread of yellow, the fastigium generally discolored, sometimes and

 with a pallid line along the position of the lateral carinae of the prozona, 
 extending also across the head where it follows the upper hinder mar- 
 gin of the eyes; above the middle of the lateral lobes, on the prozona, 
 is a more or less distinct and irregular fuscous bar, generally darkest 
 below, including on the hinder section a whitish dash in its upper part, 
 and sometimes more or less margined with pallid, especially below; 
 there is usually present, sometimes conspicuously, a narrower or broader 
 mediodorsal stripe, sometimes pale yellow or pale yellow margined more 
 or loss broadly, and generally more broadly behind than in front, with 
 reddish pink or fuscous, at other times, and especially in the female 
 where it is at least generally broader, wholly reddish pink more or less 
 infnscated. Tegmina of about the length of the abdomen in both sexes, 
 green or yellowish green, the anal area and often a little more than that 
 sometimes reddish pink, especially in the female. Legs green, the fore 
 and middle femora more or less plainly annulate with coral red before 
 the gcniculatiou, and occasionally with a line of red above the upper 
 margin of the outer face, the geniculation with a fuscous crescent both 
 on the outer and inner side; hind tibiae pale bluish green, becoming 
 more or less yellowish apically, the spines pallid on tbeir basal, blackish 
 brown on their apical half; hind tarsi pale green, more or less yellow- 
 is]^, especially at the apices of the joints. Supraanal plate of female 
 triangular, subacutely but bluntly angulate, of about equal length and 
 breadth, the margins nearly straight, the middle of either half with a 
 rather broad moderately elevated ridge, the two converging beyond the 
 middle of the plate and inclosing a deep basal sulcus; furcula consist- 
 ing of a pair of minute rounded lobes, nearly twice as distant as their 
 width; cerci considerably shorter than the supraanal plate, simple, reg- 
 uh.rly conical on basal half, the apical half subequal, bluntly pointed, 
 very feebly dowucurved ; infracercal plates almost as long as the supra- 
 anal plate, inconspicuous; last dorsal segment broadly rounded and 
 rather deeply emargiuate.

 Dr. J. A. Allen found the insect in Iowa only in dry prairies on the 
 grass, excepting that the least-marked specimens occurred in groves, 
 and there only. 
 
 Occasionally a specimen, and especially a female, is found in which 
 there is no trace of ferruginous on the tegmina, which are then green 
 with a pallid stripe along the dividing line between the discoidal and 
 anal areas, reminding one of H. riridis or H.festivus. * 
 
 The specimen above referred to from Orizaba, a female, differs 
 slightly in its somewhat abbreviated tegmina, and the mottled mark- 
 ings of pallid yellow and green upon the lateral lobes of the prono- 
 tum; it possibly indicates another species.

 lateral margins of the frontal costa, especially its upper portion, and 
 the apex of the fastigium are tinged or flecked with roseate, also occa- 
 sionally seen on the lateral carinae of the face; vertex more or less

 pallid at base, slightly darker and sometimes infuscated at tip, nearly 
 as long as (female) or much longer than (male) head and pronotum 
 together. Prouotum tectilbrin with a feeble blunt and equal median 
 cariua, which is often but not always, sometimes conspicuously, pink 
 roseate; prozoua much longer than, in the male half as long again as, 
 the metazona, rugulose, the raised portions generally more or less 
 yellowish and having often a transverse, never a longitudinal trend; 
 the metazona equally rugulose, but with a distinct longitudinal trend 
 to the raised portions; hind margin obscurely and obtusely angulate. 
 Tegmina green or yellowish green, the longitudinal veins being yellow 
 and the ground green ; they taper to a roundly acuminate tip and are of 
 variable length in both sexes, but always considerably longer than the 
 pronotum, in the male usually about two-thirds the length of the abdo- 
 men, in the female generally varying from two-thirds as long as to quite 
 or nearly as long as the abdomen; wings pellucid green, with green 
 veins. Hind femora green, the outer half of the upper surface below 
 the carina often roseate, and the inner surface generally pale yellow; a 
 faint sign of a pregenicular roseate auuulation often appears ; hind tibiae 
 green, the spines pallid or yellowish green with black tips. Supraanal 
 plate of male triangular, with slightly sinuate sides, the apex some- 
 times acute, sometimes rounded, with a rather broad and deep median 
 sulcus in the basal half, bounded by a rather high and acute ridge on 
 either side, between which and the margin is a rather deep and very 
 broad valley; a slight median sulcus appears in the apical half; furcula 
 consisting of a pair of approximate, little protruding, triangular lobes; 
 cerci delicate and slender, tapering gently and more on basal than on 
 apical half, though sometimes the apical half is nearly equal, bluntly 
 acuminate at tip and with the outer half distinctly incurved; apical 
 tubercle prominent, conical, more or less appressed; sometimes slightly 
 transverse as viewed from behind, and occasionally (as in the figure; 
 by accident in drying?) bifid.

 This species can hardly be confounded with any other, though it 
 bears a close general resemblance to Campylacantha acutipennis, from 
 which it is strongly separated by the prominence of the base of the 
 lateral margin of the subgenital plate of the male. It is dimorphic in 
 wing length. 
 
 18. AEOLOPLUS, new genus, 
 (a/o/lo?, variegated; o-rcXov, armor.) 
 
 Body relatively short and stout, considerably enlarged at the meta- 
 thorax, even in the male. Head normal, the eyes moderately distant, 
 not very prominent except sometimes in the male, the summit well 
 arched, the fastigiurn slightly silicate between the eyes, the frontal 
 costa moderately broad, subequal, plane or nearly plane; antennae 
 moderately stout, cylindrical, equal, slightly longer (male) or slightly 
 shorter (female) than the head and pronotum together. Pronotum 
 stout, regularly increasing in size from in front backward, the disk 
 gently convex transversely, the prozona slightly and independently 
 tumid, with no or an exceedingly feeble median carina, distinguishing 
 it from the flat carinulate metazona; .posterior margin of pronotum 
 very obtusely angulate, the angle more or less rounded; prozona about 
 half as long again as the metazona, generally slightly broader than 
 long or quadrate. Prosternal spine conical, erect; interval between 
 niesosternal lobes of male about twice as long as broad, often clepsydra! 
 from the convexity of the inner margins of the lobes, of female vary- 
 ing from the same to quadrate, the metasternal lobes attingent or sub- 
 attingent in the male, a little distant in the female. Fore and middle 
 femora considerably tumid in the male, the hind femora relatively 
 short and stout, occasionally furnished interiorly in the male with a 
 basal tooth protecting the calcaria when the tibiae are closed upon the 
 femora. Tegmina generally completely developed, but often somewhat 
 abbreviate, rarely lobate. Subgenital plate of male with the lateral 
 margins very strongly ampliate and arched at the base, and furnished 
 with a distinct but not very prominent subapical tubercle, the apical 
 margin of the plate forming its inner base; furcula scarcely or not 
 apparent; cerci tapering, apically very slender, simple; terminal seg- 
 ments of female abdomen more or less considerably abbreviated, the 
 ovipositor only partially exserted. 
 
 Aeoloplus regalis may be taken as the type. 
 
 This genus is closely related to Hesperotettix, and these two genera 
 are the only ones in the section of Melanopli with ampliate base to the 
 lateral margins of the subgenital plate, in which the abdomen terini-

 nates in a tubercle distinct from the margin itself, though it is a rather 
 common feature in the alternate section; accordingly I have arranged 
 these two genera in such an order that they directly follow those of the 
 other section, and the remaining genera in such sequence as that 
 arrangement required. It is composed of insects of a much heavier 
 build than Hesperotettix, the principal distinctions between the two 
 genera being given in the table (page 11). 
 
 The genus is confined to the western half of the United States from 
 the Yellowstone to the Mexican border, 1 but it does not appear to have 
 been found in California 2 or farther east than western Kansas and 
 Nebraska; it does not reach the prairie region, and is mostly found 
 apparently at elevations not far from 3,000 to 6,000 feet above the sea. 
 
 According to Bruner, Acoloplus turnbullii and Acoloplus chenopodii, 
 and therefore probably all the members of the genus, or at least those 
 of the division A 1 of the following table, are similar in their food 
 habits, confining their attention "almost entirely to the various species 
 of plants of the botanical family Chenopodiaceae, which abound in the 
 regions where they occur, being particularly fond of the grease-wood, 
 Sarcobates vermicular is"

 (Plate V, fig. 5.)- 
 
 Head pallid fuscous, flecked on the sides with brown and with a 
 mediodorsal blackish brown stripe, which fills the narrow sulcus of the 
 fastigiuin and passes backward much broadened, continuing with less 
 depth of color but with equal width upon the pronotum, as far as the 
 posterior limit of the prozoua; a similar but weaker brown stripe 
 passes from behind the eye a similar distance, broader and weaker 
 upon the pronotum; antennae pale salmon red, paler at base; frontal 
 costa equal, as wide as or slightly wider than the interval between the 
 eyes, feebly sulcate below the ocellus; fastigium narrowly and rather 
 deeply sulcate, the sul cation of equal width but varying depth. 
 Ground color of pronotum yellowish brown, the posterior margin dis- 
 tinctly but obtusely and not sharply angulate, the disk of the prozona 
 distinctly though but slightly transverse, with no median carina. 
 Prosterual spine short, conical, erect. Tegmina considerably surpass- 
 ing the abdomen, exceptionally slender, with very slight subbasal 
 expansion of the costal area, subacuininate apically, brown, but with 
 the larger distal portion pellucid, flecked with brown by the alternately 
 deeper and lighter brown of the veins, the cross- veins mostly white or 
 pellucid; wings not much shorter than the tegmina, not very broad, 
 the veins blackish brown anteriorly, brownish blue in the anal area. 
 Hind femora dull luteous, the outer face with three more or less con- 
 fluent, transverse, blackish brown stripes, indicated by transverse fus- 
 cous cloudy bars on the upper faces, the arc of the geniculation heavily 
 marked in black; hind tibiae pink, becoming gradually plumbeous 
 distally, the spines pallid on the basal, black on the apical half. 
 Supraanal plate of male subtriangular with sinuous sides and a pro- 
 duced and rounded apex, the surface plane or nearly plane, but with 
 two pairs of very slight longitudinal ridges, one pair bounding the 
 basal median sulcation, which narrows distally and terminates beyond 
 the middle of the plate, the other lateral, oblique, and less sharp, prox- 
 imally at the lateral margin, distally a little removed from it and ter- 
 minating at a similar distance from the base as the other pair; furcula 
 barely indicated by an attingent pair of scarcely projecting disks; 
 cerci rapidly tapering at base, nearly the entire distal three fifths sub- 
 equal, slender, cylindrical, straight, blunt-tipped, surpassing slightly

 2. AEOLOPLUS ELEGANS, new species. 
 (Plate V, fig. 6.) 
 
 Head pale greenish yellow, the vertex deeper yellow, with a medio- 
 dorsal pale bluish green stripe from the front of the fastigium back- 
 ward; antennae pale salmon, pallid at base and fnscesceut at tip; 
 fastigium broadly and very shallowly sulcate throughout; frontal costa 
 rather broader than the interspace between the eyes, equal, faintly 
 sulcate below the ocellus. Pronotum very pale testaceous with a slight 
 greenish tinge, more pronounced on the metazona, with a very broad 
 pale bluish green mediodorsal stripe inclosing one of pale testaceous, 
 and with some greenish clouds upon the lateral lobes of the prozona; 
 posterior margin very obtusely angulate, the angle rounded; prozona 
 feebly transverse with no median carina. Prosternal spine short, con- 
 ical, erect. Tegmina considerably surpassing the abdomen, exception- 
 ally slender for the genus, with scarcely any subbasal expansion of the 
 costal area, tapering very gradually, the apex well rounded, subpel- 
 lucid with greenish yellow veins; wings not much shorter than the 
 tegmina, fully twice as long as broad, the veins greenish, faintly infus- 
 cated. Hind femora dull luteous, with three transverse fusco-olivaceous 
 stripes, more or less confluent on the outer face; hind tibiae pale 
 glaucous, the spines paler glaucous with black tips. Supraanal plate 
 of male somewhat distorted in the only specimen seen, but apparently 
 triangular, with slight median emargination of the sides and a shallow 
 basal sulcus, bounded by convergent walls; furcula practically absent; 
 cerci rather stout, tapering on the basal half, equal and hardly less than 
 half as wide as the base on the apical half, the tip rounded and very

 uing across the pronotum, where it is very much broader, broadest in 
 the middle or at the hinder extremity and sometimes inclosing a slender 
 thread or stripe of testaceous; there is also a lateral blue-green band, 
 its upper limit at the summit of the lateral lobes of the pronotum, 
 which starts from behind the eye and crosses the prozona, where it is 
 much the widest, occupying from a third to a half the length of the 
 lateral lobes, and occasionally suffusing the metazona; rest of pro- 
 notum brownish testaceous, sometimes with a yellow tinge; frontal 
 costa equal, as wide as the interval between the eyes, slightly depressed 
 at the ocellus; antennae orange. Pronotum obtusely angulate poste- 
 riorly, the median cariua distinct on the metazona, feebly indicated on 
 the prozona in the male and occasionally in the female. Prosternal 
 spine rather slender, conical, reaching the level of the pectus. Tegmina 
 generally slightly longer than the abdomen, especially in the male, 
 sometimes only as long as it, rather broad, especially just beyond the 
 base, brownish green, with darker green flecking.s and yellowish cross- 
 veins; beyond the subbasal enlargement they taper regularly and gently, 
 the tip rounded; hind wings a little shorter than the teginina, moder- 
 ately broad, the veins bluish green, slightly infuscated next the costa. 
 Hind femora testaceous yellow, with two broad angulate and sagittate 
 blue-green bands, darkest above; hind tibiae pale blue-green, pallid 
 at base and pallescent apically, the spines pallid, with the apical half 
 blackish brown. Supraaual plate of male subtriangular, with broadly 
 angulate sides, as long as broad, the acutely angulate tip rounded, the 
 surface nearly plane but faintly elevated to the slight ridges which 
 mark the boundaries of the rather broad and shallow median sulcus 
 that extends over the basal half, narrowing slightly in its passage: 
 there is besides, on either side, an oblique and narrow ridge, extending 
 from the extreme outer base toward the middle of the distal half of the 
 opposite side, terminating halfway there; furcula consisting of a pair 
 of scarcely projecting, minute, attingent, angulate or subaugulate lobes; 
 infracercal plate as long as the supraanal, concealed by the recumbent 
 cerci; cerci feebly compressed, of the length of the supraanal plate, 
 tapering in the basal half, beyond slender, cylindrical, subequal, but 
 apically tapering and feebly cur ved downward and inward; subapical

 It lias also been reported from Nebraska (Dodge) and Wyoming 
 (Brunei 1 ). 
 
 The single specimen from Grand Junction is of an exceptionally 
 small size, a female only 17 mm. long. 
 
 This is the largest species of the genus and is not uncommon at the 
 eastern base of the Eocky Mountains in Colorado. I have considered' 
 it probable that this is the species described by Dodge under the name 
 Caloptenus regalis, but the description does not very well apply to it. 
 I am guided partly by a sketch of the markings of the tegmina sent 
 me many years ago by Mr. Dodge, and partly by the impossibility of 
 applying the description to any other known species.

 marked in fusco olivaceous, and there are sometimes fuscous clouds in 
 the .same region, but nowhere distinct. Prosternal spine as in Ae. 
 ref/alis. Tegmina much surpassing the abdomen in both sexes, at 
 their broadest as broad as the metazona, beyond the subbasal enlarge-

 feebly, especially along the middle, with fuscous, the longitudinal veins 
 interruptedly fuscous and pallid in the apical half; wings slightly 
 shorter than the tegmina, moderately broad, distinctly less than twice 
 as long as broad, the veins and cross-veins glaucous. Hind femora 
 and tibiae precisely as in Ac. reyalis. Supraanal plate of male trian- 
 gular, with strongly sinuate sides and produced and rounded apex, 
 with a basal, apically narrowing, moderately broad median sulcus, 
 bounded by sharp but low walls and reaching halfway across the plate, 
 and an oblique ridge on each side, as in Ac. reyalis, but much less 
 prominent; furcula indicated merely by a pair of thickenings of the 
 inner angles of the mesially parted terminal dorsal segment; cerci as 
 in Ac. reglis, but with the apical portion less slender and straighter;

 This species is very closely allied to Ae. regalis, but has much longer 
 tegmina, is slighter in form, has a less pronounced subapical tubercle 
 to the male abdomen, and differs slightly in color and markings as well 
 as iu the abdominal appendages.

 broadening mediodorsal blackish stripe on the prozoua, including a 
 similarly widening testaceous thread or stripe; upper half or rather 
 less of the lateral lobes of the protfona with a similar more or less 
 distinct blackish brown belt, generally accompanied by a testaceous

 genae sometimes clouded with fuscous; a broad blackish stripe, usually 
 broadening posteriorly, extends from the front of the fastigium across 
 the summit, nearly occupying the whole of the fastigium except the 
 sides of the expanded portion and sometimes invading this; a broader 
 band extends longitudinally behind the eyes; antennae pale salmon 
 red, more or less deeply infuscated apically; fastigium not sulcate; 
 frontal costa nearly or quite as broad as the narrowest space between 
 the eyes, shallowly sulcate below the ocellus. Pronotum varying from 
 testaceous to dark brownish yellow, the metazona generally feebly infus- 
 cated in parts, especially on the disk, the prozona and generally the 
 front half of the metazona with a broad, obscurely bordered, blackish 
 fuliginous, mesial stripe, sometimes including a yellowish thread; upper 
 half of the lateral lobes of the prozona similarly colored, forming a 
 broad bar, which sometimes extends as a cloud upon the metazona; 
 posterior margin obtusely angulate, the angle rounded; median carina 
 on the metazona only. Prosternal spine conical or pyramidal, rather 
 pointed, moderately long. Tegmina brown, variably necked with dull 
 yellowish, the basal portion of the anal vein often so marked, falling 
 distinctly short of the tip of the abdomen, the costal margin somewhat 
 but not greatly expanded beyond the base, beyond tapering regularly,

 tegmina. Hind femora clay yellow, thrice broadly banded with blue 
 black, the bands generally more or less blended on the outer face, the 
 whole genicular arc inky black; hind tibiae glaucous, suffused apically 
 with pale yellow, and with a narrow subbasal yellowish annulus, the 
 pallid spines black tipped, the tarsi clay yellow. Supraanal plate of

 The species was originally reported from a between Eed Buttes and 
 Independence lioek, Wyoming, " but it has since been recorded by 
 Bruner (doubtless in some cases by mistake for some of the allied spe- 
 cies here first separated) from Garden City, Finney County, Kansas, 
 western Nebraska, Arizona, New Mexico, Montana and the Pacific 
 Coast. 
 
 According to Bruner, this species in the Yellowstone region "only 
 feeds upon two species of plants, as nearly as I could ascertain by 
 observation, viz., the i pigweed' and a small greenish white plant of a 
 similar nature. Those found on the pigweed are somewhat glaucous 
 yellow, while those feeding on the other plant are more of a whitish 
 color, mingled with greenish blue instead of greenish yellow," the color 
 of the insects resembling to a considerable degree that of the plants 
 on which they feed.

 especially noticeable is a dark medioclorsal stripe, extending from the 
 middle of the vertex between the eyes, where it is not half so broad

 here, the slight lateral carinae moderately abrupt and obtuse, the pos- 
 terior border obtusely angulated, the angle rounded. Prosternal spine 
 very short, straight, stout, pyramidal, pointed. Tegmiua not much 
 shorter than the abdomen, obscure brown, mottled with many pale and 
 darker spots (due to the broken color of the veins), mostly arranged 
 longitudinally in the median field; the costal field is broadly enlarged 
 near the base, and beyond it the whole tapers nearly to the rounded 
 tip,' veins of the apical half of the preanal field of the wings dusky or 
 blackish. Hind femora with two median, angulate, moderately broad, 
 brownish fuscous bands, the arc of the geniculation black; hind tibiae 
 pale dull glaucous, pale at the base, the spines black-tipped. Supra- 
 anal plate of male triangular, nearly as long as broad, flat, with a 
 shallow median furrow of moderate width in the basal half and a slen- 
 der mesial groove at apex; furcula consisting of a pair of minute, 
 attingent, triangular lobes; cerci broad at base, rapidly tapering on 
 the compressed, conical, basal half, very slender and nearly equal on

 I have seen no other males .of this species since its first description, 
 but I have before me three new females, which from the greater brevity 
 of their tegniina I am inclined to place here rather than in Ae. tiirnbullii 
 (from which the females at least are with difficulty separated), and 
 which come from Colorado (Canon City, Fremont County, Morrison and 
 Uhler. U.S.N.M. [Xo. 716])'. The specimen collected by Morrison was 
 obtained on the plains at an elevation of 5,000 feet, and is almost wholly 
 grass-green with the lighter parts yellowish green.

 The color of the only specimens seen are probably changed somewhat 
 from their having been killed in spirits and are now of a light dead-leaf 
 color; probably in life they were uniformly testaceous, with perhaps 
 a greenish tinge. The pronotum shows, at least on the prozona, signs 
 of a broad, paler, mediodorsal band, and a similar baud on the middle 
 of the lateral lobes; the outer face of the hind femora shows indications 
 of a pair of dusky transverse bauds, mesial and extramesial, and the 
 apical half or more of the hind tibial spines are black. The fastigium of 
 the vertex is scarcely in the least impressed, excepting at its very base 
 between the eyes; the frontal costa has a row of puucta on either side,

 and fails to reach the clypeal suture. Prozoua feebly and sparsely, 
 metazona densely and rather strongly, punctate on the disk, the for- 
 mer anteriorly with a submarginal transverse series of more distinct 
 puncta, becoming mesially a double series; the posterior sulcus of the 
 prozona swerves broadly backward and is completely continuous; that 
 in front of it is rather short, not infringing on the lateral lobes, rigidly 
 transverse and feebly continuous. Supraanal plate of male triangular, 
 with almost straight lateral margins, subacuminate apex, fully as long- 
 as broad, with a pair of subrnedian, subparallel, rather elevated ridges, 
 fading posteriorly, inclosing a deep median sulcus; furcula consisting 
 only of a rather distinct but obtuse angle on either side of a rectangu- 
 lar median emargination of the last dorsal segment; cerci very slender 
 (slenderer than appears by the figure), as long as the supraanal plate, 
 tapering considerably in the basal half, equal and very feebly incurved 
 in the apical half, apically blunt; infracercal plates rather broad, hardly 
 narrowing apically, shorter than the infraanal plate.

 Nevada. I am not at all confident that the two belong together, and 
 my description is therefore based almost wholly upon the male.

 Uniform in coloring throughout, and probably testaceous (all speci- 
 mens seen have been immersed in alcohol), except that the transverse 
 sulci of the pronotum appear to have been marked with black or fus- 
 cous, there are some slight fuscous markings on the upper half of the 
 lateral lobes of the prozona, the tegmiua are clouded and obscurely 
 dotted with fuscous, the hind femora are sometimes twice barred with 
 fuscous and have a large fuscous lunule on the geniculation, and the 
 tibial spines are black tipped. The eyes of the male are tolerably 
 prominent; the fastigium, except at apex, is distinctly and uniformly 
 but not deeply sulcate; the frontal costa is subequal, depressed at but 
 not sulcate below the ocellus, percurrent. Prozoua punctate above 
 only in the submarginal sulcus; metazona densely and rather strongly

 Pale yellowish testaceous, uniform, the only variations from it being 
 in the pale reddish antennae, chocolate brown eyes, the faint, fuscous, 
 crowded, and delicate punctuation of the submarginal sulcus of the 
 prozona and of the whole of the inetazona, the bluish main rays of the 
 wings, the feeble, plumbeo-fuscous, sagittate banding of the hind 
 femora, the narrow purplish crescent of the genicular lobes and the 
 very pale purplish hind tibiae, the spines of which are yellowish in the 
 basal, black in the apical half. The eyes of the male are very large 
 and prominent, thefastigium pretty deeply and rather narrowly sulcate 
 between the eyes, the frontal costa moderately broad, subequal, nowhere 
 sulcate, and rather indistinctly percurrent. Posterior sulcus of the 
 prozona swerving backward mesially to form a very broad W, and yet

 Body stout, compact, heavy, generally, and especially in the female, 
 very broad at the metathorax. Head stout, slightly broader below 
 than above, the genae full ; eyes separated by a wide space, wider and 
 generally much wider than the broad frontal costa; front well rounded, 
 vertical, the frontal costa prominent, broad, and generally somewhat 
 sulcate, at least above; antennae slender for such bulky insects, equal, 
 shorter and generally much shorter than the hind femora. Thorax very 
 stout, the pronoturn very short, not covering the whole of the meso- 
 notum, truncate at either extremity, the metazona only about half as 
 long as the prozona and rugulose, while theprozona is smooth; lateral 
 lobes sometimes separated from the dorsum by distinct rugae. Pro- 
 sternal spine very much abbreviated, becoming in the female a mere 
 blunt tubercle, and in the male very short and conical; mesostethium 
 and metastethium together, in both sexes, but particularly in the female, 
 no longer or scarcely longer than broad; the interspace between the 
 mesosternal lobes wide in both sexes, but showing a remarkable degree 
 of variation quite unknown in any other of the genera of Melanopli;

 men of male apically clavate, upturned, the subgenital plate long and 
 tumid, without apical tubercle; furcula absent or (in one species) rep- 
 resented by feeble lobes: cerci simple, conical, straight. 
 
 B. obesa (Thomas) is the type. 
 
 This somewhat remarkable genus is, so far as known, confined to the 
 extreme northwestern United States, but will probably be found also 
 in British Columbia. It extends from the Pacific to Montana and 
 Wyoming, and has so far been reported only north of the latitude of

 and some of the genera peculiar to the South, no other genus of 
 Melanopli has so limited a range. 
 
 ANALYTICAL KEY TO THE SPECIES OF BRADYNOTES.

 costa; hind femora fully three times as long as pronotum and relatively slender; last 
 
 dorsal segment of male abdomen with slight lobes for furcula 1. li'ispida (p. 81). 
 
 A-. Interspace between the eyes nearly twice the least width of the frontal costa; 
 hind femora distinctly less than three times as long as prouotum and relatively 
 stout; last dorsal segment of male abdomen quite unarmed. 
 
 6 1 . Interspace between mesosternal lobes not (male) or at most a little (female)

 half to nearly as distant as the mesosternal lobes (female) ; male cerci about as 
 long as the supraanal plate.

 lobes subcontiguous (male) ; last segment of male abdomen not greatly upturned. 
 
 d l . Interspace between mesosternal lobes of male scarcely more than half the 
 
 width of the lobes themselves, the metasternal interspaces in the female

 Body moderately stout, very slightly compressed, but little enlarged 
 in the metathoracic region, even in the female, feebly pilose. Head 
 full, the vertex gently tumid, the interspace between the eyes not 
 much greater than the least width of the frontal costa, the fastigium 
 considerably declivent, slightly expanding apically, broadly sulcate,

 anteriorly punctate in the male, the lateral margins moderately prom- 
 inent but rounded 5 frontal costa moderately broad, a little broader 
 than the basal joint of the antennae, subequal, sulcate below the ocel- 
 lus and sparsely punctate; eyes moderately large, more prominent in 
 the male than in the female, about as long 'as the infraocular portion 
 of the genae, anteriorly truncate, especially in the female; antennae 
 a little more (male) or a little less (female) than half as long again 
 as head and pronotum together. Pronotum subequal, in the female 
 feebly constricted in the middle and slightly broadened posteriorly: 
 metazona less than half as long as the prozona, the posterior sulcus of 
 the latter as distinct as the anterior which divides it in the middle, all 
 the sulci cutting the slight and equal median carina; posterior mar- 
 gin truncate or very faintly and broadly emarginate; mesonotum fully 
 half (male) or distinctly less than half (female) as long as the meta- 
 notum. Interspace between the mesosternal lobes a little cuneiform, 
 about as large as (male) or a little larger than (female) the slightly 
 transverse lobes; interspace between the inetasterual lobes much less 
 than half (male) or considerably more than half (female) the width of 
 the mesosternal interspace. Fore and middle femora of male consid- 
 erably but not greatly inflated ; hind femora slender, twice as long as 
 head and pronotum together. Abdomen relatively slender, with a 
 sharp but slight median cariua, the extremity scarcely enlarged in 
 the male (as viewed from above) and but gently upturned; supraaual 
 plate of male shield shaped, the proximal half of the lateral margins 
 ridged and the broad median sulcus margined with prominent ridges, 
 higher in the proximal than the distal half; furcula consisting of a 
 pair of small, moderately distant beads; cerci as long as the supra- 
 anal plate, subcouical, but tapering much more rapidly in the basal 
 than the apical half, the tip very feebly down-curved ; iufracercal plate 
 of either side large, sulcate, much exposed, nearly meeting its mate, 
 and extending slightly beyond the supraanal plate. 
 
 The body is brownish ochraceous, heavily banded with blackish 
 brown, the proportions of the two varying somewhat. The head 
 (excepting the vertex and a broad stripe behind the eyes which are 
 blackish brown) and the fore and middle legs are dirty ochraceous, 
 darker in the female than in the male, with an olivaceous tinge, and the 
 same color is found on the whole under surface of the body and the lower 
 half or less of the lateral lobes of the pronotum ; the broad dark band 
 behind the eyes continues across the upper half of the lateral lobes 
 and the whole of the abdomen, bordered above by an ochraceous stripe, 
 which begins between the eyes, bordering their upper margin, and con- 
 tinues to the end of the abdomen, often becoming duller in color as it 
 approaches the extremity and is more narrowly separated from its 
 mate; sometimes the intervening dark stripe, which occupies most of 
 the vertex of the head, and is always broader anteriorly than posteri- 
 orly, is interrupted at the metazona and on the meso- and metanota, so 
 that the lighter bands here unite. Hind femora varying from brownish

 to yellowish fuscous, feebly clouded, especially above, with fuscous in 
 the middle and in the middle of the distal half, the under and inner 
 surfaces more or less deeply tinged with coral red; hind tibiae and 
 tarsi fusco-luteous, only the apical half or less* of the spines blackish or 
 brown. 
 
 Length of body, male, 18.5 mm., female, 21 mm.; antennae, male, 9.5 
 mm., female, 10.5 mm. ; pronotum, male, 3.6 mm., female, 4.5 mm.; hind 
 femora, male, 10.75 mm., female, 12.5 mm. 
 
 One male, 3 females. Colville Valley, eastern Washington, July 24 
 (L. Bruner; Museum Comparative Zoology). 
 
 In the exceptional length of the hind femora, the feeble metathoracic 
 enlargement of the body, and the development of the furcula, as well as 
 in some minor features, this is the most aberrant species of the genus.

 Bradynotes opimus BRUNER!, Can. Ent., XVII (1885), p. 15. 
 
 Body similar in shape and clothing to B. hispida. Head full, the 
 vertex gently tumid, the interspace between the eyes twice as great as 
 the least width of the frontal costa, the fastigium strongly declivent, 
 narrowing rather than expanding anteriorly, broadly but shallowly 
 snlcate, the lateral margins rather prominent but rounded; frontal 
 costa rather broad, much broader than, sometimes twice as broad as, 
 the basal joint of the antennae, generally a little sulcate throughout, 
 especially in the male, punctate at the margins; eyes not very large, 
 scarcely more prominent in the male than in the female, about as long 
 as the infraocular portion of the genae, anteriorly truncate particularly 
 in the female; antennae a little longer (male) or a little shorter (female) 
 than the head and pronotum together. Pronotum subequal, expand- 
 ing posteriorly a very little, especially in the female; metazona half 
 (female) or slightly less than half (male) as long as the prozoua, the sulci 
 of the latter equally indistinct, and neither of them cutting the median 
 carina, which is nearly obliterated on the prozona, especially in the 
 female; posterior margin as in B. hispida; mesonotum more than half 
 (male) or less, sometimes much less, than half (female) as long as the 
 metanotum. Interspace between the mesosternal lobes as wide (female) 
 or hardly more than half as wide (male) as the lobes themselves, the 
 metasternal lobes subcontiguous (male) or half as distant as the meso 
 sternal (female). Fore and middle femora of male somewhat inflated; 
 hind femora short but not very stout, hardly half as long again as head 
 and pronotiyn together. Abdomen relatively rather slender with a slight 
 and blunt median carina, the extremity scarcely enlarged in the male, as 
 viewed from above, and but gently upturned. Supraanal plate of male 
 subtriangular with rounded apex, about equally long and broad, tumid 
 by reason of a pair of very coarse, elevated, rounded ridges, with a

 ,very deep basal sulcus between them; furcula absent; cerci slightly 
 longer than the supraanal plate, subconical, faintly compressed, a 
 little downcurved apically, tapering with regularity; infracercal plates 
 inconspicuous. 
 
 Body griseo fuscous, mottled, the face and inferior surface of body 
 sordid brownish yellow, feebly punctate with fuscous. Vertex and 
 fastigium brownish fuscous, the lateral margins of the latter feebly 
 enlivened witli orange, and the former mottled or streaked with livid 
 brown. Both thorax and abdomen are heavily mottled with blackish 
 fuscous, much more heavily in some individuals than in others, which 
 is apt to be conspicuous in a pair of subdorsal bands, sometimes con- 
 fined to the posterior edges of the segments, and to leave a narrow 
 lighter dorsal stripe between them; the lower portion of the lateral 
 lobes of the pronotum is always lighter than the upper half, which is 
 often marked by a more or less distinct, sometimes abbreviated, broad 
 black or blackish band, generally deeper in tint on its inferior half. 
 Hind femora blackish fuscous feebly clouded with dull yellowish, the 
 whole under surface and under portion of its outer face clay yellow; 
 hind tibiae light coral red (male) or dark coral red on apical half and 
 extreme base, passing into purplish red on the basal half (female), the 
 spines blackish on their apical half at most.

 3. BRADYNOTES EXPLETA, new species. 
 (Plate VI, fig. 7.) 
 
 Body similar in shape and clothing to B. hispida, except that it is 
 relatively a trifle stouter at the metathorax, especially in the female. 
 Head broad and full, the vertex gently tumid, the interspace between 
 the eyes nearly or quite twice as great as the least width of the frontal 
 costa, the fastigium strongly declivent, shallowly sulcate, the lateral 
 margins rather prominent, especially in the male, but rounded; frontal 
 costa rather broad, considerably broader than the basal joint of the 
 antennae, feebly sulcate if at all, and sparsely punctate, especially at 
 the margins; eyes as in B. caurus (antennae more or less broken in all 
 specimens seen). Pronotum regularly expanding posteriorly, very 
 slightly in the male, distinctly but not greatly in the female; metazona 
 about half as long as the prozona, the sulci of the former equally but 
 feebly impressed, all cutting the feeble median carina, which is obso 
 lescent on the prozona in the female ; mesonotum nearly half (female) or 
 
NO. 1124. REVISION OF THE MELANOPLISCUDDEB. 85 
 
 much less than half (male) as long as the metanotum. Interspace 
 between the mesosternal lobes almost as broad as the lobes themselves 
 (male, female), the metasternal lobes slightly distant (male) or fully 
 three-fourths as distant as the mesosternal lobes (female). Femora as 
 in 7?. caurus. Abdomen relatively slender, compressed, with a distinct 
 but not prominent median carina, the extremity in the male slightly 
 enlarged, as seen from above, and somewhat upturned; terminal 
 appendages of male differing from those of B. caurus only in that the 
 supraamil plate is a little more pointed, and the cerci coarser, a trifle 
 shorter, more bluntly tipped, and not curved downward so much 
 apically. 
 
 Body brownish fuscous above, sordid yellow below. Face livid brown, 
 flecked with fuscous points ; the ridged margins of the fastigium coral 
 red, at least in. the male; behind the eyes, in front of the position for 
 the lateral carinae of the pronotum, is the beginning of a slender and 
 feeble yellowish stripe, which crosses interruptedly to the pronotum 
 and is there lost; below it, the upper half of the lateral lobes are dark 
 brown, almost blackish, at least on the prozona, while below the lobes 
 are much lighter colored. The abdomen is more or less flecked, espe- 
 cially laterally, at the posterior margins of the segments with testaceous, 
 and there is a more or less conspicuous or broken piceous lateral band 
 on the basal half of the abdomen. The hind femora are colored as in 
 B. caurus, but the hind tibiae are coral red in the male, sordid yellow 
 apically tinged with red in the female, feebly incurved, the spines black 
 tipped. Lower external half of anal cerci of male distinctly darker 
 than the upper. 
 
 Length of body, male, 16.25 mm., female, 28 mm.; pronotum, male, 
 4 mm., female, 4.5 mm.; hind femora, male, 8.25 mm., female, 14 mm.

 This species is very closely allied indeed to B. caurus. 
 
 4. BRADYNOTES PINGUIS, new species. 
 (Plate VI, fig. 8.) 
 
 Body stout and clumsy, considerably enlarged in the metathoracic 
 region, especially in the female, weakly and briefly pilose. Head full, 
 the vertex gently tumid, the interspace between the eyes broad, about 
 twice the breadth of the narrowest part of the frontal costa, the fastig- 
 ium strongly declivent, considerably but broadly sulcate, its lateral 
 margins ridged, continuous with the sometimes elevated, always dark- 
 colored bortlers of the frontal costa; the latter broad, much broader than 
 the basal joint of the antennae, variably sulcate, punctate but sparsely 
 except on the margins; eyes rather large, more prominent in the male 
 than in the female, equally truncate anteriorly in the two sexes, as long 
 as the infraocular portion of the genae; antennae somewhat louger 
 (male) or a trifle shorter (female) than head and pronotum together. 
 
86 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL.XX. 
 
 Pronotuin regularly, and in the female considerably, enlarging posteri- 
 orly, with distinct (male) or indistinct (female) lateral carinae on the 
 prozona, which is twice (male) or almost twice (female) as long as the 
 metazona, its sulci approximated and equally distinct, but not so dis- 
 tinct as that separating the pro- and metazona and, unlike it, not cut- 
 ting the median carina, which is yet often subobsolete on the prozona 
 and especially on its posterior half, particularly in the female; exposed 
 portion of mesonotuin about half (male) or hardly more than. a fourth 
 (female) as long as the metanotuin. Interspace between the rneso- 
 sternal lobes three-fourths (male) or fully (female) as wide as the lobes 
 themselves, the metasternal interspace half (male) or three-fourths 
 (female) the width of the mesosternal interspace. Fore and middle 
 femora pretty strongly inflated and arcuate in the male, the hind 
 femora stout and heavy, hardly if at all more than half as long again 
 as head and pronotnm combined, the hind tibiae stout. Abdomen 
 stout, tapering and then apically enlarged and considerably upturned 
 in the male; supraanal plate of male triangular, shorter than its basal 
 breadth, with a pair of broad, gently tumid ridges, which unite into a 
 single median ridge, leaving between them in the basal half a shallow 
 sulcus; furcula wanting; cerci as long as the supraanal plate, sub 
 conical, slightly compressed, tapering a little more rapidly in basal 
 than in apical half, rather blunt at tip, straight throughout; infracercal 
 plate much shorter than the supraanal, scarcely perceptible. 
 
 Body brownish fuscous above much marked with clay yellow, beneath 
 almost wholly clay yellow, more or less infuscated in the female. The 
 head is more or less obscure yellow, the vertex at summit brownish fus- 
 cous, limited at most to a narrow median and two equally narrow sub- 
 median streaks, the latter continued along the marginal ridges of the 
 fastigium down the sides of the frontal costa, but at the apical third of 
 the fastigium more or less interrupted by or suffused with dull red; the 
 antennae are yellow at base, gradually passing into fuscous. On the 
 dorsum of the thorax and the front at least of the abdomen, the fuscous 
 is more or less obscurely punctate or flecked with yellowish, and along 
 the median line of the abdomen there is a distinct yellowish stripe begin- 
 ning on the meso- and metanota as a mere thread; the prevailing tint 
 of the lateral lobes of the pronotum is yellowish, but there is a more or 
 less distinct blackish fuscous oblique bar on the prozoua just above the 
 middle, merging posteriorly in the general obscurity of the metazona; 
 there is a distinct broad blackish fuscous oblique band crossing the 
 meso- and metapleura, and the middle of the sides of the basal abdomi- 
 nal segments are piceous. The fore and middle legs are fusco-luteous; 
 the hind femora yellowish, more or less obscured with fuscous and 
 spotted with fuscous on the inner upper face and the outer face, which 
 is generally almost black along its upper half; hind tibiae and tarsi 
 coral red, brighter in the male than in the female, the external series 
 of spines yellow with black apices. The sides of the supraanal plate of

 the male show a black stripe, and the cerci, mesially yellow, are 
 obscured with fuscous both above and below.

 Body wholly similar in form and clothing to that of B. pinguis, or it 
 is even stouter in the metathoracic region in the female. Head not 
 differing essentially from B. pinguis, and eyes and antennae with the 
 same structure. Pronotum with similar but rather less distinct and 
 continuous lateral carinae; metazona half (male) or distinctly less than 
 half (female) the length of the prozona, the two sulci of the latter 
 approximated, the hinder of them less distinct than the anterior, which 
 is as well marked as that separating the prozona from the metazoua, 
 but neither traverse the median carina, which is equal and distinct 
 though slight throughout; exposed portion of mesonotum half (male) 
 or much less than half (female) as long as the metanotum. Sternal 
 interspaces as in B. pinguis, as also the femora. Abdomen stout, 
 with a more or less distinct median carina, in the male tapering and 
 then apically enlarging and upturned; supraanal plate of male tri- 
 angular, as long as its basal breadth, otherwise as in B. pinguis; fur- 
 cula absent; cerci as long as the supraanal plate, straight, tapering 
 regularly in the basal three-fifths, beyond equal or subequal, blunt 
 tipped ; infracercal plates blunt tipped, reaching the tip of the supraanal 
 plate. 
 
 General color blackish griseous, more or less necked with brown. 
 Face and genae below the eyes varying from pale to pinkish livid, punc- 
 tate with black, especially below, and divided by black stripes following 
 the edges of the frontal costa and the lateral carinae of the face and 
 also, generally, the arcuate posterior carinae of the genae, and an oblique 
 line of punctures subparallel to it below the middle of the geiiae; summit 
 of head with a median and a pair of arcuate lateral narrow black stripes,

 the former the darker, the latter extending upon the lateral margins of 
 the fastigium, on the anterior part of which they are supplanted by 
 red ; antennae testaceous near the base, blackish beyond. Prozona with 
 a large central blackish spot on the disk, inclosing a pair of testaceous 
 dots, laterally disposed ; anterior and posterior margins of the pronotum, 
 especially in the female, occasionally enlivened feebly with red; lateral 
 lobes lighter below than above, speckled, with a broad, somewhat 
 broken, black median baud crossing the prozona. Abdomen varying 
 from grizzly to blackish, the posterior edges of the segments dotted 
 with minute longitudinal spots, and some of the posterior segments 
 marked with a central, triangular, testaceous spot, seated on the pos- 
 terior border. Hind femora with the outer face generally altogether 
 black, occasionally lighter and marked with a central, oblique, pale dash 
 above; upper and lower faces pale testaceous, the inner side of the 
 upper face with a pair of black bars; hind tibiae deep purplish at base 
 (with the basal outer tubercle deep red) passing into deep red beyond 
 the middle, the under surface clay yellow; the spines of the basal half 
 pale, of the apical half reddish, all black tipped. Male cerci clay yellow, 
 edged below with blackish ; supraaual plate yellow mesially, blackish 
 laterally.

 Idaho and southern Montana. 
 
 Since describing B. opimus, I have been able to compare it with the 
 types of Thomas's Pezotettix obesus and find they are not distinct. The 
 species is very close to B. pinguis, but differs from it in its markings, 
 particularly in its darker antennae, its much less developed median 
 abdominal stripe and its differently colored hind tibiae, and also in the 
 more continuous and more developed median carina on pronotum and 
 abdomen, and the slightly differing abdominal appendages of the male. 
 It is evidently the commonest and most widely spread of the species of 
 Bradynotes.

 Body similar in form to that of B. Mspida, but with excessively sparse 
 and feeble pilosity. Head full, the vertex gently tumid, the interspace 
 between the eyes twice as broad as the narrowest part of the frontal

 costa, the fastigiuin declivent, shallowly sulcate, with elevated rounded 
 margins, continuous with the slightly elevated margins of the upper 
 part of the frontal costa. The latter broad, subequal, feebly broaden- 
 ing below, much broader than the basal joint of the antennae, feebly 
 sulcate in the male, and sparsely punctate; eyes not very large, slightly 
 more prominent, and anteriorly slightly less truncate in the male than 
 in the female; antennae about as long as (female) or a little longer 
 than (male) the head and pronotum together. Pronotum subequal, but 
 slightly enlarging posteriorly, especially in the female, with the Mutest 
 possible indications of lateral carinae in the male, the metazona, espe- 
 cially in the male, fully half as long as the prozona, the sulci of the 
 latter scarcely less distinct than the principal sulcus, and similar, cut- 
 ting the median carina, which is often but not always obsolete between 
 the sulci and sometimes over the whole prozona; exposed portion of 
 mesonotum fully half (female) or less than half (male) as long as the 
 metanotum. Interspace between the mesosternal lobes fully equal to 
 the lobes themselves (male, female), the metasternal interspace half 
 (male) or much more than half (female) as wide as the mesosternal. 
 Fore and middle femora considerably tumid in the male; hind femora 
 moderately stout, about two and a half times as long as the pronotum. 
 Abdomen with a distinct median carina, a little compressed, in the male 
 tapering from the base, scarcely enlarged apically, but considerably 
 upturned; supraaual plate of male fully as long as its basal breadth, 
 dorsally ridged as in B. obesa; no furcula; cerci slightly longer than the 
 supraanal plate, slightly compressed but externally tumid, tapering 
 on the basal half, the apical subequal, moderately stout, slightly down- 
 curved and rounded at the extremity; infracercal plates produced on 
 the inner side nearly to the extremity of the supraanal plate. 
 
 General color and markings much as in B. obesa, but with lighter col- 
 ored antennae, and with the upper half of the lateral lobes of the pro- 
 notum very dark, generally forming a distinct broad baud in marked 
 contrast to the lower half of the same, and in the female in contrast to 
 the somewhat lighter griseous disk of the pronotum, the band crossing

 frontal costa, but not nearly twice so broad, the fastigium very strongly 
 declivent, sulcate, with prominent lateral ridges which apically diverge 
 slightly; frontal costa broad, considerably broader than the basal joint 
 of the antennae, not constricted above, more or less sulcate, especially 
 in the male, fading just below the ocellus, and very feebly punctate; 
 eyes not very large, more prominent in the male than in the female, 
 and roundly truncate anteriorly, alike in both sexes, but only in the 
 male as long as the intraocular portion of the genae; antennae consid 
 erably longer (male) or somewhat shorter (female) than head and pro 
 notum together. Pronotuin regularly enlarged posteriorly, a little more 
 in the female than in the male, with no trace of lateral carinae, the pro- 
 zoua fully twice (male) or nearly thrice (female) as long as the metazona, 
 its approximated sulci similar to but less distinct than the principal 
 sulcus, and like it continuous, the median carina hardly existing except 
 on the metazona, where it is feeble; exposed part of mesonotum about 
 half as long as the inetanotum (male, female), the posterior border of 
 the latter slightly (male) or distinctly (female) emarginate. Interspace 
 between mesosternal lobes considerably wider than (male) or twice as 
 wide as (female) the lobes themselves, the metasternal interspace nearly 
 as great. Fore and middle femora very slightly tumid in the male, the 
 hind femora moderately slender, nearly two and a half times as long as 
 the prouotura. Abdomen stout with a distinct but slight median carina 
 in the male, tapering on the basal half, hardly enlarging apically but 
 considerably upturned; supraanal plate of male small, triangularly 
 shield shaped, broader than long, apically angulate, with an unimpor- 
 tant sulcate median ridge on basal half meeting a transverse ridge, 
 beyond which it is depressed; no furcula; cerci very short, conical, 
 blunt, not reaching beyond the middle of the supraanal plate; infra- 
 cereal plates large, mesially ridged, reaching as far as the supraanal 
 plate. 
 
 Body griseo-fuscous, flecked and tinted with sordid luteo-fuscous, 
 lighter beneath, darker above. The vertex and mesial parts of the fas- 
 tigium are fuscous, the lateral ridges of the latter lighter colored, but 
 without a trace of red. The lower half of the lateral lobes of the pro- 
 notum are as light as the under surface, and the upper half as dark 
 as any other part of the body, so as to form a faint dark baud, but the 
 contrasts are not great; the meso- and inetauota, and the posterior 
 borders of the abdominal segments are nearly black; the antennae are 
 sordid luteous at the base, fuscous beyond. Hind femora externally 
 clouded and feebly twice banded obliquely with fuscous; hind tibiae 
 very dull luteous, clouded apically with fuscous in the female, the spines 
 black or brown tipped.

 This species is remarkable for the slenderness of the fore and middle 
 femora of the male and the brevity of the cerci, exposing so fully the 
 infracercal plates; it has considerably longer hind legs than B. referta, 
 which it most resembles in general appearance.

 Body stout, compact, transversely subquadrate, thinly pilose. Head 
 large, broad, a little prominent, with the eyes fully as wide, at least in 
 the male, as the length of the lateral carinae of the raetazona, the sum- 
 mit well arched, raised a little above the level of the pronotum, the 
 fastigiuni rapidly descending and forming an obtuse angle with the very 
 straight and slightly receding face; eyes rather small but very promi- 
 nent in both sexes, nearly as broad as long and no longer (female) or 
 scarcely longer (male) than the anterior infraocular portion of the 
 geuae; interspace between the eyes exceptionally broad, in the female 
 nearly as broad as the upper aspect of the eyes; fastigiuni feebly con- 
 vex as far as the front margin of the eyes, in front of which it is 
 depressed; frontal costa only moderately broad, much narrower than 
 the interspace between the eyes, obsolescent below the ocellus j owing 
 to the breadth of the face, the lateral carinae are more than usually 
 divergent; antennae slender, long, about half as long as the body, oven 
 in the female. Pronotum feebly subsellate, the anterior margin flaring 
 to receive the head, and the inetazona both expanding and having its 
 dorsum raised at a slight angle with the prozona; front margin slightly 
 convex; hind margin slightly more convex, feebly emargiuate, even in 
 the macropterous forms; disk of prozona feebly convex transversely, 
 of metazona plane, passing with a distinct angle into the vertical lateral 
 lobes, more distinct on inetazona than on prozona, so that, at least on 
 the inetazona, there are distinct lateral carinae, besides a well-defined 
 percurrent, median carina; prozona smooth excepting its subrugose 
 anterior margin, subtrans verse, half as long again as the punctato- 
 rugulose metazona, cut rather deeply in the middle by a straight trans- 
 verse sulcus, followed at less than half the distance to the inetazona 
 by a still deeper, scarcely arcuate, percurrent sulcus, from which there 
 runs backward, on the middle of either side, a short impressed line. 
 Prosternal spine stout, erect, conical; meso- and metastethia together 
 distinctly longer than broad in both sexes, rapidly narrowing behind, 
 so that the portion posterior to the metasternal lobes is only about half 
 the greatest width of the metastethium; interval between the meso- 
 sternal lobes in both sexes distinctly transverse, broader than the lobes 
 themselves; metasternal lobes rather distant (male) or distant (female), 
 at least as widely separated as the breadth of the frontal costa.

 rounded apically. 1 Fore arid middle femora a little tumid in the male; 
 hind femora not very long iior stout, subcompressed ; hind tibiae with 
 nine to eleven, usually ten, spines in the outer series; aroliuin of un-

 I have retained the name quercus rather than longipennis for this 
 species for several reasons: It was first called by this name both by 
 Eiley and Bruner; it was first described in its earlier stages under this 
 name by Packard (copying Bruuer's description, which was unaccom- 
 panied by a name); and the name is a far more fitting one than Jongi- 
 pennis, considering that the insect appears both in brachypterotis and 
 macropterous forms, and that it is normally brachypterous, as the basal 
 divergence of the tegmina shows. It may also be called a mistake (in 
 which entomologists generally have erred, myself among them) to give 
 any species of Orthoptera a name derived from the length or brevity of 
 the tegmina. On the other hand, indubitably the species was first fully 
 described from mature examples under the name longipennis, a name 
 given by Riley on the assumption that it was distinct from his earlier 
 named quercus. As both names were given by the same naturalist, no 
 personal question enters, and I trust that in this settlement of the ques- 
 tion at its first raising all will agree. 
 
94 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. xx. 
 
 Our knowledge of the natural history of this species depends almost 
 entirely upon what Bruner wrote in his first account of it in 1887, 
 before it was named. He found it in destructive numbers in Washing- 
 ton County, Texas, feeding upon the post oak and a completely defoli- 
 ating the trees of the forest even to the very topmost twigs. 77 He gives 
 the following account of its history and habits: 
 
 The egg pods are deposited in the ground about the bases of trees or indifferently 
 scattered abont the surface among the decaying leaves, etc., like those of all other 
 ground-laying species. The young commence hatching about the middle of March, 
 and continue to appear until into April. After molting the first time and becoming 
 a little hardened they immediately climb np the trunks of the trees and bushes of 
 all kinds and commence feeding upon the new and tender foliage. They molt at 
 least five or six times, if we may take the variation in size and difference in the 
 development of the rudiments of wings as a criterion. The imago or mature stage 
 is reached by the last of May or during the first part of June. 
 
 The species is very active and shy in all its stages of growth after leaving the egg. 
 The larva and pupa run up the trunks and along the limbs of trees with considerable 
 speed, and in this respect differ considerably from all other species of locusts with 
 which I am acquainted. I am informed that the mature insects are also equally 
 wild and fly like birds. They feed both by day and night; and I am told by those 
 who have passed through the woods after night, when all else was quiet, that the 
 noise produced by the grinding of their jaws was not unlike the greedy feeding of 
 swine. 
 
 The colors of the insect in life during the early stages are given in 
 the same place by Bruner and copied by Packard. 
 Kiley had previously reared the species in Missouri on oaks.

 Form of body and of head as in Melanoplus; antennae as there, but 
 rarely (Podisma variegata, e. g.) they are as long as the hind femora. 
 Prouotum variable, but always short, sometimes subcylindrical, some- 
 times (and especially in the female) expanding considerably from in front 
 backward, never mesially contracted, generally with very feeble trans- 
 verse sulci, the lateral lobes obliquely truncate apically on the anterior 
 section; front margin truncate, hind margin usually subtruucate or 
 truncate and even emarginate, but sometimes also very obtusaugulate, 
 the prozona generally considerably longer than the metazona, sometimes 
 twice as long, smooth or very faintly punctate, the metazona generally 
 very densely punctate; median cariua distinct, but sometimes slight on 
 the metazona, generally feeble sometimes obsolete on the prozoua; lat- 
 eral carinae very variable, the disk sometimes passing quite insensibly 
 into the lateral lobes, sometimes so abruptly and angularly as to form 
 tolerably distinct lateral carinae. Prosternal spine always prominent, 
 generally bluntly conical; meso- and metastethia together, at least in 
 the male and nearly always in both sexes, distinctly longer than the 
 width of the metastethium, the latter narrowing posteriorly, so that the

 portion behind the metasternal lobes is not (or is hardly) more than 
 half the greatest width of the metastethiuin and is twice as broad as 
 long; interspace between inesosternal lobes of male distinctly trans- 
 verse, 1 as broad or almost as broad as the lobes themselves; of the 
 female distinctly or strongly transverse, often fully twice as broad as 
 long, generally as broad as and sometimes broader than the lobes them- 
 selves; metasternal lobes of male generally distinctly distant, occa- 
 sionally approximate, never attingent; of the female generally more dis- 
 tant, the interspace in the latter sex generally as broad as or broader 
 than the frontal costa. Tegmina never fully developed, often wholly 
 wanting, and when present either lateral, and then generally shorter 
 than the short pronotum, or else attingent or overlapping, and then at 
 most reaching the middle of the hind femora, and usually subacuminate. 
 Hind femora moderately long and slender, the inferior geuicular lobe 
 as in Melanoplus and the spines of the hind tibiae generally rather fewer 
 than in that genus, nine to eleven, by exception eight or twelve, in 
 number in the outer series. Abdomen more or less compressed, the 
 sides of the first segment with or (in some apterous Old World forms) 
 without a distinct tympanum, the extremity in the male more or less 
 clavate and recurved; subgenital plate of very variable form, often 
 prolonged to a distinct apical conical tubercle involving the apical 
 margin, the lateral margins basally ampliate; cerci very variable, but 
 to a less degree than in Melauoplus, not infrequently styliform, of vari- 
 able length; furcula usually developed, but only at most to a small 
 degree; ovipositor of female variable, typically exserted, but sometimes 
 exceptionally extended and at others partially withdrawn in the then 
 obtusely terminating abdomen. 
 
 The limits between this genus and Melanoplus are difficult to formu- 
 late; while there is no difficulty in separating the bulk of the species 
 in either group, there are a number which find their place almost 
 equally well in either. I have here attempted to state anew the char- 
 acters first expressed by Stal, though with such necessary modifica- 
 tions and expansions as a far larger series of forms entails. I can 
 hardly hope that the conclusions I have reached will be sustained at 
 every point, but I am confident that they must hold in the main. In 
 doubtful cases I have endeavored to determine the affinities from the 
 concurrent study of both sexes and not from either alone, which would 
 have brought about other and sometimes discordant results; and I 
 have assigned the greatest weight to the intervals between the sternal 
 lobes. 
 
 As I have here employed a different generic term from that in cur- 
 rent use in literature, I submit the following cogent reasons for the 
 necessity of the change: 
 
 The generic name Podisma was proposed in a Gallic form (Podisme) 
 
 1 A single exception is known to ine in the subapterous Japanese Podisma dairixama, 
 where it is slightly longitudinal. 
 
96 'PRO GEE DINGS OF THE NA TIONA L MUSE UM. 
 
 by Latreille l in 1825 for short- winged Acridians with a prosternal spine, 
 without specification of species. Its next use was by the same author 
 in 1829 2 in its proper Latin form, and the European species now known 
 as Pezotettix pedestris and Platypliyma giornae referred to it. The same 
 two species, and these only, are again referred to Podisma by Serville 3 
 in 1831, and to the same as a subgenus of Acridium by the same writer 
 in 1839. 4 Burin eister, 5 however, in 1840, refers these same species, and 
 these only to a new genus Pezotettix, to which he gives as a synonym 
 "Podisma Latreille ex parte:" In Burmeister's view the other portion 
 of Latreille's genus included such species as Stenobothrus parallelus 
 and Chrysochraon dispar. 6 But these latter species are excluded by 
 Latreille's definition, and in his writings I can not find that he has ever 
 mentioned any other species as appertaining to the genus than the two 
 first mentioned above. 
 
 The only other authors who had at this time employed the term were 
 Brulle 7 in 1832, who (as quoted by Fischer) referred to it only species 
 of Stethophyma and Stenobothru*] Heyer, 8 who in 1835 (?) employed it 
 for Chrysochraon dispar; Stephens, 9 who in 1835 had referred pedestris 
 only to it; and Costa, 10 who in 1836 had referred to it four supposed 
 new species appulum, campanum^ calabrum, and coimnnnis, the first 
 two of which are now regarded as synonyms of Acridium aegyptium L., 
 the third as probably a Pamphagus, and the last as giornae. In view 
 of the limitation of the genus by Serville (if Latreille ever intended 
 its greater extension), this action of Brulle and of Costa has no force, 
 and hence, if the name Pezotettix can be retained at all, it must be by 
 regarding one of the two original species as the type of Pezotettix^ the 
 other of Podisma. 
 
 As far as I can discover, the first author to refer the two species to 
 distinct genera was Fieber, 11 who in June, 1853 referred giornae to his 
 new genus Pelecyelus, and pedestris to Podisma. Also in 1853, but 
 later, his introduction being dated November, H. Fischer 12 referred the 
 former species to his new genus Platypliyma and the latter to Pezotettix. 
 Fischer has been generally followed, but it is plain that Platypliyma 
 must give way to Pelecyclus, which in its turn must yield precedence to 
 Pezotettix^ of which giornae becomes the type, while pedestris becomes 
 the type of Podisma.

 The early use of the term Podisma previous to 1853 and after 1829 
 (other than given above) also sufficiently confirms the appropriateness 
 of restoring Podixma for the species now generally included in Pezotettix; 
 for Fischer de \Valdheim 1 in 1840 used it for six species, of which the 
 first three belong to Pezotettix of modern writers, the next two to 
 Chrysochraon, while the last is not recognizable; von Borck in 1848 2 
 refers to it pedestris and frigida; and finally H. Fischer himself first 
 used it in 1849 3 forfrigida. His reasons later 4 for supplanting Podisma 
 by rezotettix can not be defended. 
 
 The type of Podisma is therefore Gryllus pedestris Linnaeus. 
 
 This genus is more widely extended than any other of the Melanopli, 
 being the only one not confined to America. It is a distinctly boreal 
 type and encircles the globe. The species are largely confined to high 
 altitudes as well as high latitudes, a number being alpine or snbalpiue in 
 their respective localities. In this country the species are known from 
 two widely separated regions; in the west, the Rocky Mountain region 
 from Alberta to northern New Mexico; and in the east from western 
 Ontario and New York to Maine. In Europe they are largely confined 
 to the mountains of southern Europe from the Pyrenees to Mount Par- 
 nassus or to Scandinavia; in Asia their distribution is less known, 
 but species occur in eastern Siberia and in Japan. 
 
 In the following pages I have fully described only the American 
 species, which are first treated separately; but I have thought well to 
 complete the account of the Melanopli by including the Old World 
 species as far as possible, figuring their abdominal appendages, giving 
 a separate table for their determination, and adding brief diagnoses of 
 two species which are unpublished. Their synonomy and distribution 
 are mostly compiled from Brunner's Prodromus Eur. Orthopteren.

 conical, ending in a blunt but not large tubercle, the apical margin 
 scarcely elevated, angulate, entire. 
 
 The colors of the above description, which are taken from life, are, 
 unless otherwise specified, drawn entirely from the female, as the sexes 
 differ considerably. The male differs in the following particulars: The 
 front of the head and the pronotuin are more yellowish, the prosterimm 
 black, the spine uniform pale green, the meso- and metasterna bright 
 green, the sternum of the abdomen yellowish-green, slightly paler than 
 the thorax, with the basal border of the segments broadly bordered 
 with black and the apical narrowly with fuscous; the whole dorsal 
 surface of the abdomen is black with a mediodorsal series of yellowish- 
 green spots and a triangular spot of the same between the middle and 
 hind coxae; a lateral row of greenish-yellow spots on the first eight 
 abdominal segments, each with a dark arcuate streak above it, opening 
 toward the brownish spiracles.

 Excepting Jackmau, Maine (Harvey), the only other place from which 
 it has been reported is "British America" (Bruner), but without further 
 specification Professor Bruner now thinks this was a mistake. " Mr. 
 Morse tells me that he has specimens taken on Kataadn, Maine, 5,200 
 feet. 
 
 In the White Mountains 1 have found this grasshopper from the 
 neighborhood of the snow arch in Tuckermans Ravine (about 4,000 
 feet) to the base of the rocky slopes on the side of Mount Washington 
 above the Alpine Garden, and at the summit of Mount Madison (5,380 
 feet) at about the same elevation. I have also taken it at the upper 
 limits of Huntingtons Ravine and about the ledge on the carriage road. 
 It frequents the close branches of the dwarf birch, Betula nana, and is 
 rarely or never seen on the ground. 
 
 Of the European insects, it is most nearly allied to Pod. baldensis, but 
 is a considerably larger insect, with heavier and stouter cerci and slen- 
 derer and longer furcula.

 I formerly compared this insect to the European Podisma alplna var. 
 montana, but it should rather be compared to Podisma pedestris on 
 account of its much shorter subgenital plate, though in its cerci it is 
 more nearly related to the former; it can not be confounded with either, 
 but is more nearly related to Podisma pedestris than to any other 
 American type. 
 
 By the kindness of Doctor Aurivillius, of Stockholm, I have received 
 one of the type specimens of StaPs Pezotettix bohetnani, and been able 
 to compare it with the types of the other nominal species mentioned in 
 the synonymy.

 by myself, but erroneously, from Sierra Blanca, Colorado, and northern 
 New Mexico ; for in different papers I have formerly referred to this

 The present species has a close general resemblance to Melano- 
 indigens, extending to the abdominal appendages of the male.

 Oregon. 
 
 Thomas's text refers to an illustration on a plate, but another species 
 was there substituted for it. His types do not appear to exist, but I 
 think there can be little doubt that this is his species, his description 
 agreeing exceptionally well and certainly applying to no other insect I 
 have seen. I am also drawn to this conclusion by notes taken many 
 years ago upon examination of his types.

 The publication of Fieber's species dates from 1853 (Lotos) and not 
 from 1854 (Synopsis), and antedates by several months the description 
 of Fischer, whose name has been hitherto accepted; for Fieber's spe- 
 cies was published in the June number of Lotos, and the preface to 
 Fischer's work is dated November. 
 
 This species occurs, according to Brunner von Wattenwyl, on hazel 
 stalks and bramble bushes. 
 
 Austrian Alps, especially the southern side, from Transylvania west- 
 ward to southern Tyrol and the Swiss canton Ticino; and in the moun- 
 tainous region bordering the upper extremity of the Adriatic, eastward.

 As Brunner points out, this is not the Podisma schmidtii of Fieber 
 ( 1.S5:$); but he nevertheless retains Fieber's name for it, because it was 
 first described by himself under that name, under the supposition that

 it was Fieber's species, and because Fieber's schmidtii and Fischer's 
 mendax are the same. By the ordinary rules of nomenclature, the 
 name schmidtii, having been applied to one species of the genus could 
 not subsequently be applied to another, even if the first were a syno- 
 nym; but it is doubly incorrect here, since schmidtii of Fieber has tbe 
 priority over mendax of Fischer. It is therefore necessary to give the 
 present species a new name. 
 
 This species is found on leafy bushes. 
 
 From Carniola eastward to Servia, southern Hungary, and Transyl- 
 vania.

 Occurs in two forms : alpina, with tegmina separate and lateral, found

 ping, half as long as the abdomen. 
 
 P. a. alpina occurs in all the higher mountains of central Europe as 
 far east as the borders of Servia. I found it extremely abundant in 
 the alpine pastures about Yillars sur Bex, Canton de Yaud, Switzer- 
 land. P. a. collina is found from Carniola and the forest of Vienna 
 through southern Hungary to Transylvania.

 On account of the extraordinary development of the subgenital plate

 Fischer deWaldheiin describes it from Verkhni-Udiusk,Transbaicalia, 
 Siberia. Specimens in my collection were collected by Parschine at 
 the same place in June, at Samonoffsk in June, at Khabarowki and 
 Tscherhjava on the Amur in May and August, and in the Desert of 
 Khorinskaya in Trausbuicalia.

 Body moderately stout, somewhat compressed, without noticeable 
 pilosity, the excessively brief and fine hairs being exceedingly scattered. 
 Head large by being protuberant, not broader than the pronotum, the 
 face moderately oblique and the genae feebly tumescent ; vertex broadly 
 arched, not elevated above the pronotum; fastigium very broad, 
 tumid, feebly decliveut, anteriorly rounded; eyes rather long oval, 
 fully half as long again as broad, especially in the female, anteriorly 
 subtruncate, separated above by an exceptionally wide interval, almost 
 or quite twice as wide as the rather broad frontal costa; antennae slen- 
 der, about as long (in the female at least) as the head and pronotum 
 together. Pronotum long, compressed, subequal, narrowed above 
 anteriorly, the disk nearly plane but the prozona slightly tumid, with 
 percurrent and equal median cariua, distinct, percurrent, equal and 
 feebly arcuate lateral carinae, the transverse sulci feebly incised, the 
 hind margin produced, but very obtusangulate, the inetazona flaring

 not stout, conico-cylindrical; meso- and metastethia together much 
 longer than broad in both sexes, the latter narrowing rapidly behind, 
 so that the portion behind the lobes, more than twice as broad as long, 
 is scarcely more than half as broad as the metastethium ; interspace 
 between mesosternal lobes much longer than broad in both sexes and 
 much narrower than the lobes themselves, the nietasternal lobes more 
 (male) or less (female) approximate, the interspace in the female scarcely 
 so broad as, in the male much narrower than, the frontal costa. Teg- 
 mina abbreviate, overlapping, acuminate. Hind femora very long, the 
 inferior genicular lobe subpallid, uniform, the hind tibiae with eight to 
 twelve spines in the outer series. Sides of the first abdominal segment 
 with a distinct tympanum. Subgenital plate of male with no apical 
 tubercle, its lateral margins ampliate, basally rectangulate ; cerci lamel- 
 late, subpyriform, tapering strongly and unequally, the apex produced, 
 subacuminate and incurved. Abdomen of female regularly tapering, 
 the ovipositor normally exserted, the valves nearly straight with acute 
 but smooth costae. 
 
 The genus is represented by a single species found in the western 
 Mississippi valley. When published by Brunner, no species was de- 
 scribed or even named, but the species here given is the one upon 
 which the genus was founded and is therefore the type.

 oblique excision of the costal margin and the strong apical arcuation of 
 the inner margin, subacuminate, a little longer than the pronotum, 
 overlapping, brownish castaneous, the ulnar vein broadly marked with 
 pale flavous edged anteriorly with blackish fuscous. Fore and middle

 apex acutangulate, the margins feebly and broadly elevated, the median 
 sulcus not very deep, terminating with its bordering ridges in the center 
 of the plate; furcula ?; cerci very broad and somewhat tumid at base, 
 forming a compressed and slightly tortuous cone, tapering rapidly and

 Body moderately stout, rarely slender, generally feebly compressed, 
 more or less but generally feebly pilose. Head moderately, rarely not 
 at all, prominent, generally but little if any longer than the prozona, 
 unless the latter (as rarely) is distinctly transverse; face almost verti- 
 cal or a little oblique, its angle with the fastigiuin rarely less than 75; 
 vertex gently tumid; eyes rounded oval, never more generally less than 
 half as long again as broad, the anterior margin subtruncate or feebly 
 convex, separated above rather or very narrowly, at most but little 
 farther apart than the width of the equal or subequal frontal costa; 
 fastigiuin more or less sometimes very declivent, passing insensibly into 
 the frontal costa, always more or less sulcate or with elevated lateral 
 margins, generally more deeply sulcate in the male than iu the female; 
 frontal costa moderately prominent, generally sulcate below, usually 
 more or less punctate; antennae slender, of variable length, but never 
 very short, never longer than the hind femora, and rarely if ever more 
 than twice as long as the pronotum, even when this is subtruiicate pos- 
 teriorly. Pronotum generally subcompressed, rarely or never twice as 
 long as the average breadth, generally only half as long again as the 
 average breadth even in the male, the metazona generally more or less 
 flaring, its disk plane and densely punctate, while that of the prozona

 front or only in the very slightest degree, at most faintly punctate and 
 generally distinctly longer than the metazona; front margin generally 
 truncate or subtruncate, hind margin obtusangulate to a greater or less 
 degree, rarely subtruncate; median carina always distinct on the meta- 
 zoua, generally much less so on the prozona, often subobsolete between 
 the sulci and never wholly wanting; lateral carinae typically obsolete, 
 but often indicated by a distinctly abrupt though rounded shoulder, 
 rarely becoming carinate; lateral lobes vertical or sub vertical, espe- 
 cially below, often feebly tumid above on the prozoua, and generally 
 marked by a piceous postocular band, crossing either the prozoua alone 
 or the whole pronotum, not infrequently broken or maculate. Proster- 
 nal spine variable, but always prominent; meso- and metastethia to- 
 gether distinctly longer than broad in both sexes; interspace between 
 mesosternal lobes generally longer or much longer than broad, never 1 
 in the least broader than long, even when the sides of the interspace 
 are very divergent posteriorly (male) or generally quadrate but more 
 variable than in the other sex, sometimes as narrow as there but more 
 frequently subtransverse, occasionally in brachypterous forms dis- 
 tinctly transverse, as a general rule wider than in the other sex (female), 
 in both always distinctly, generally much, narrower than the lobes them- 
 selves, except in the few instances 2 where it is distinctly transverse in 
 the female; metasternal lobes generally attingent or subattingeut, 
 rarely only approximate (male), or generally approximate or subap- 
 proximate, the interspace between them generally narrower than the 
 frontal costa (female); metasternum rapidly narrowing posteriorly, so 
 that the portion behind the lobes is not, or is hardly more than, half 
 the greatest width of the metasternum, but is more than twice as broad 
 as long. Tegmina always present, but either abbreviate and then 
 lateral, attingent, or overlapping, sometimes shorter and sometimes 
 longer than, but generally nearly the length of, the pronotum and usually 
 more or less acuminate apically; or they are fully developed and then 
 usually about attain or a little surpass the tips of the hind femora, 
 tapering more or less but very gradually and apically well rounded, at 
 a distance from the apex equal to the breadth of the tegmina dis- 
 tinctly narrower than the metazona, the intercalates and cross veins 
 of the discoidal area (except in the macropterous forms of the dimor- 
 phic species, M. dawsoni and M. marginatus) relatively numerous at 
 least in the apical fourth arid usually throughout, the venation in gen- 
 eral sharp and clearly defined, the humeral vein straight and only api- 
 cally arcuate, nearly always terminating either on the apical margin 
 or only a short distance before it, running for some distance almost 
 exactly parallel to the costal margin or merging insensibly into it, the

 area intercalata always, even in macropterous forms of dimorphic spe- 
 cies, extending- somewhat, generally considerably, beyond the middle 
 of the tegmina. Hind femora moderately long and slender, the infe- 
 rior genicular lobe with at least a darker basal spot or transverse 
 band, the hind tibiae with a variable number of spines (generally nine 
 to fourteen) in the outer series, by rare exception eight only. Abdo- 
 men more or less compressed, the sides of the first segment with a dis- 
 tinct tympanum, the extremity in the male more or less sometimes 
 strongly clavate, usually considerably recurved, the subgenital plate of 
 variable form, but always with the lateral margins ampliate at the 
 base and with no distinct apical tubercle, though not infrequently api- 
 cally produced or subtuberculate and frequently tumescent; cerci 
 exceedingly variable in form, often enlarging apically, always lamellate 
 excepting (the lakinus series three species) where they are basally 
 globose, never styliform, rarely (the puer series two species) in the 
 least substyliform, generally incurved and of about the length of the 
 supraanal plate; furcula usually developed and to a very variable 
 extent, and with variable form; pallium rarely exserted; ovipositor of 
 female generally fully exserted. 
 
 The type of the genus is Acridium femur -rubrum De Geer. 
 
 The number of species of Melanoplus is so exceedingly great that I 
 have endeavored to display their relationships in part by separating 
 them into groups. Noticing how seldom the characteristic parts of the 
 male abdomen agreed in the short-winged and long- winged forms, not- 
 withstanding that one would look for their close agreement, I have first 
 divided them in the following table into those which are fully equipped 
 with ample organs of flight and those in which these organs are more 
 or less undeveloped, and then have subdivided each according to other 
 characteristics, endeavoring thus to bring into close contiguity those 
 which appeared to be most nearly allied. I was not a little surprised to 
 find in how few instances it was possible to combine the brachypterous 
 and macropterous species in any one of these groups. Even in most 
 of these, and especially in the dawsoni series (itself somewhat heter- 
 ogeneous en either side), the collocation is rather forced. The groups 
 into which I have divided the macropterous forms are far more nat- 
 ural than those of the brachypterous species, and the portion of the 
 table relating to the former is therefore much more satisfactory than 
 the other. I have more than once completely remodeled that relating 
 to the brachypterous species, but with no greater success than in that 
 now presented. 
 
 Much to my surprise, I find but a couple of species in this genus (M. 
 dawsoni, M. marginatus) in which there is complete dimorphism shown 
 in the full development on the one hand and extreme abbreviation on 
 the other of the organs of flight. In other species, especially in M.fasci- 
 atus and M. extremis, there is considerable variability, but nowhere 
 else is it carried to this extreme. It is, however, found in DendroiettiXj

 Plwetaliotes, and Oedaleonotm, each of which is represented by a single 
 species. I have treated this matter more fully in the Introduction. 
 
 The present genus, so richly endowed with species, is naturally very 
 widely distributed, though so far as known it is completely confined to 
 the continent of North America, and even does not occur, so far as 
 reported, 1 south of Mexico. Within this region it is as widespread as 
 all the other genera, combined. It extends from the arctic circle in 
 Alaska and on the Mackenzie River, and from northern Labrador and 
 perhaps southern Greenland on the north, to the extremity of Florida 
 and southern Mexico on the south, and from the Atlantic to the Pacific. 
 It is, however, far richer in species in the west than in the east. Only 
 seventeen of the one hundred and thirty-one species are found exclusively 
 east of the Mississippi River ? though four other eastern species barely 
 cross it; while in the Eocky Mountain region and west of it, and there 
 only, forty-nine* species are known, while thirty-two others are found 
 only west of the Mississippi River and seven western species barely x 
 cross it to the east; six species, as stated in our introduction, range 
 from Atlantic to Pacific; one occurs only north of our national bound- 
 aries in Labrador, while nineteen others inhabit Canada; twelve are 
 found only in Mexico, with ten others which it possesses in common 
 with the United States. 
 
 'These figures show the western preponderance of the species better 
 than auy summary of the twenty-eight groups into which I have divided 
 the genus, which, besides being rather unequal in the number of con- 
 tained species, often show an extremely wide distribution or more than 
 one center of distribution, in the latter case indicating, perhaps, the 
 imperfection of the grouping. Still, leaving out the five groups, each 
 of which contains one or more transcontinental species, it will be noted 
 that there are three others which compass the continent the mancus 
 (five species), plebejus (five species), and robustus (five species) series. 
 Of the twenty remaining, one-half, viz, the flabellifer (six species), bow- 
 ditchi (six species), glaucipes (two species), utahensis (three species), 
 devastator (eight species), aridus (three species), rusticus (seven spe- 
 cies), borckii (six species), cinereus (six species), and packardii (five 
 species) series extend westward to the Pacific; while only five the 
 impudicus (one species), dawsoni (seven species), puer (two species), 
 inornatus (three species), and punctulatus (two species) series reach 
 eastward to the Atlantic coast; and the remaining five the lakinus 
 (three species), indigens (one species), alien! (two species \ augustipen- 
 nis (four species), and texanus (five species) series are found exclu- 
 sively, or almost exclusively, west of the Mississippi River. 
 
 One-half of the series are represented in Mexico, showing rather 
 
 'One species, M. lorealis, is reported, in lift., by Brunner to occur at Valdivia, 
 Chile; as its only other known localities are in the arctic regions, I am inclined

 exceptional diversity for its twenty-two species, while ten series are 
 represented in the twenty species hitherto found in Canada. Nearly ^ 
 all the series have a large latitudinal distribution, the most limited 
 in this respect being: in the north, the utahensis series (three species), 
 from Washington and Alberta to Utah and Colorado, and the iudi- 
 gens series (one species), confined to Idaho ; and in the south the 
 lakinus series (three species), from Nebraska to central Mexico, the 
 impudicus series (one species), found only in Georgia and Mississippi, 
 the aridus series (three species), from Arizona to Jalisco, the puer 
 series (two species), found in Texas and Florida, and the inonmrus 
 series (three species), occurring in Illinois, Indiana, North Carolina,

 simplicity's sake, the length of the plate is here considered its extent parallel to the 
 lateral margin (or that margin itself) as seen from the side; its breadth, what would 
 be its length along the ventral line were it regarded as one of the abdominal 
 segments.

 In this small and compact group the prozona of the male is longitu- 
 dinal, and the interspace between the mesosternal lobes in the same 
 sex longer than broad, sometimes twice as long as broad. The anten- 
 nae are rather short. The tegmina are but little longer than the pro- 
 notum, overlapping, and apically acuminate. The hind tibiae are glau- 
 cous (or pale red) with nine to twelve (normally ten) spines in the outer 
 series. 
 
 The supraanal plate is subtriangular, with rather plane surface, 
 except for the rather prominent ridges bordering and forming between 
 them the median sulcus; the furcula consists of a pair of pointed slen- 
 der teeth but little longer than the last dorsal segment; the cerci are 
 very peculiar, enlarging and bullate beyond the base, but with angu- 
 lar imirgins, sulcate inferiorly, compressed but longitudinally convex 
 exteriorly, abruptly narrowing beyond the middle and incurved, ending 
 in a superior, short, flattened finger directed toward the tip of the 
 supraanal plate; the subgenital plate is very short and apically very 
 broad, subconical, with a strongly and abruptly elevated though 
 laterally brief apical margin. 
 
 The three species belonging here are rather bulky insects, rather 
 above the medium size for the genus, and they range from southwestern 
 Nebraska and Colorado to central Mexico.

 sternal lobes half as long again as broad (male) or subquadrate (female), 
 the metasternal lobes attfngent (male) or approximate (female.) Teg- 
 inina abbreviate, overlapping, lanceolate, sharply pointed, longer than 
 the pronotum, fully twice as long as broad, their inner and costal mar- 
 gins about equally convex. Extremity of male abdomen a little clavate, 
 considerably recurved, bluntly conical, the supraanal plate triangular,

 base, extending inward and upward from the basal swelling; subgeni- 
 tal plate short, considerably broader at apex than long, because the 
 extreme posterior margin is produced to form a rather large rounded 
 elevation nearly as high as broad. 
 
 The general color is a brownish griseous, tinged below with yellcw- 
 ish; the antennae are dark and sometimes darker apically; along the 
 top of the head and pronotum is a blackish fuscous rather broad 
 median stripe, sometimes broadening in patches, sometimes obsolete; 
 the upper half of the lateral lobes of the prozona is marked by a 
 broad blackish fuscous belt, which is often separated from the front 
 margin and the frequent extension of the band to the eyes by a nar- 
 row yellow line. The teginina are uniformly griseous, with a slender 
 median line of alternate yellowish and fuscous flecks, often obsolete. 
 The hind femora are lighter or darker testaceous, with two very broad, 
 oblique, blackish purple belts, which do not reach the pale orange 
 under surface; hind tibiae dull glaucous, the spines pale at base, black

 It is also reported from southwest Nebraska (Bruner). 
 
 This species is very closely allied to the last, differing from it in its 
 narrower interspace between the sternal lobes, the oblique bands on 
 the outer face of the hind femora, the more distant forks of the furcula 
 of the male, and the stouter apical process of the subgeuital plate; 
 the cerci are much the same.

 Pale testaceous (alcoholic specimens). Head not prominent, uniform 
 in coloring except for a sometimes obsolete median black stripe on sum- 
 mit, and a broad postocular piceous baud; vertex feebly tumid, not or 
 slightly elevated above the pronotum, the interspace between the eyes 
 half as broad again (male), or nearly twice as broad (female) as the first 
 anteunal joint: fastigium steeply declivent, silicate throughout, more 
 broadly in the female than in the male; frontal costa percurreut, rather

 geuae; antennae testaceous, nearly two-thirds (male) or one-half (female) 
 as long as the hind femora. Pronotum compressed, unusually equal, 
 scarcely or not expanding on the metazona, the disk very uniform,

 faintly tumid lateral lobes without forming lateral cariuae; a broad 
 piceous belt, sometimes obscured, occupies the upper half of the lateral 
 lobes of theprozona; median carina distinct, percurrent, equal; front 
 margin subtruucate, hind margin very obtusangulate; prozoua dis- 
 tinctly (male) or feebly (female) longitudinal, about a fourth longer

 by the angularity of the principal sulcus. Prosternal spine rather 
 long, appressed conical, a little retrorse, bluntly pointed; interspace 
 between mesosternal lobes subequal, a little longer than broad (male) 
 or transverse but narrower than the lobes (female). Tegmiua abbre-

 a little contracted in the middle; furcula consisting of a pair of rather 
 distant, moderately slender, scarcely tapering, blunt, dark denticula- 
 tions, overlying the outer slopes of the subinedian ridges of the supra- 
 anal plate, and extending over the plate by only a little more than the 
 length of the last dorsal segment; cerci strongly cornpressed-bulLite 
 just beyond the base, the bullate portion broader than long and exte-

 This species differs from the preceding two in the uniformity of the 
 pronotura, which does not expand posteriorly, and has a uniformly 
 sharp median cariua throughout; it is also lighter bodied and less 
 heavily marked. 
 
 2. FLABELLIFEK SERIES. 
 
 In this series, one of the few which combines macropterous and bra- 
 chypterous forms, the male prozona is feebly or distinctly longitudinal, 
 occasionally quadrate, the interspace between the mesosternal lobes of 
 the same sex varying from quadrate to half as long again as broad, or 
 somewhat more. The tegmina are either fully developed, though at 
 most but slightly surpassing the hind femora, much and irregularly 
 maculate; or half as long as the abdomen, heavily marked in the dis- 
 coidal field and subacuminate; or shorter than the pronotum and then 
 apically rounded. The length of the tegmina in each species, however, 
 is fixed. The hind tibiae are blue, with nine to eleven spines in the 
 outer series, or, in some brachypterous forms, red, with ten to thirteen 
 spines in the outer series. 
 
 The supraanal plate is triangular, rather longer than broad, with no 
 or slightly developed transverse ridges. The furcula is minute or sub- 
 obsolete, except in a single instance where it is small. The cerci are 
 broad,' often excessively broad and nabellate, enlarging from the base 
 toward the middle, at least in the macropterous forms, rarely as much 
 as twice as long as broad, broadly rounded apically. The subgeuital 
 plate is short and broad, sometimes with a slight apical tubercle, the 
 lateral margins straight, the apical margin not elevated, or only in a 
 single instance. 
 
 M. rileyanus is the most aberrant form, having very brief tegmma,

 the furcula longer than the last dorsal segment, and the lateral margins 
 of the subgenital plate slightly elevated apically. 
 
 The species, six in number, are evenly divided between macropterous 
 and brachypterous forms and this is the only homogeneous series of 
 Melanoplus in which they are so of small or rather small size, and are 
 found only in the district to the west of the Mississippi and mainly in 
 the Cordilleran region. They have not been reported north of the 
 United States, and a single species has been found to extend south of 
 our boundary in northern Mexico; while another species is known only 
 from California and is the only one occurring west of the Sierra Nevada, 
 (the same species, M. rileyanus, mentioned above).

 broadening posteriorly, passes from between the eyes to the back of 
 the head, but seldom continues, and then less deeply, upon the proiio- 
 tum; the face and genae vary from yellow to testaceous and are sel- 
 dom blotched by dusky colors, excepting on the genae; the antennae 
 are of a lighter or darker testaceous, and are scarcely infuscated at tip; 
 a more or less broken black patch occupies the upper part of the 
 anterior half of the lateral lobes. The tegmina are dark brownish 
 cinereous, with a slender median yellow stripe, frequently broken by 
 quadrate fuscous or blackish spots, and similar spots are scattered 
 rather distantly all over the tegmiua, giving them an unusually 
 speckled appearance; wings hyaline, the veins glaucous, except ante-

 3. BOWDITCHI SERIES. 
 
 In this series the male prozona is slightly longitudinal, and the inter- 
 space between the mesosternal lobes exceptionally narrow, being more 
 than twice, in the male.several times, as long as broad, while the meta 
 sternal lobes are attingent over considerable space in the male, approxi- 
 mate in the female. The tegmina, especially those of the male, are 
 rarely, and then but little, maculate, always fully developed and sur- 
 passing the hind femora; the hind tibiae are green or blue, with nine to 
 eleven, usually ten, spines in the outer series. The antennae are of very 
 unequal length in the two sexes. 
 
 The supraanal plate is more or less clypeate, the apex always well 
 angulate, and the median sulcus almost or quite obsolete; the most 
 striking feature is the furcula, which -consists of a pair of long, very 
 broad, parallel, depressed plates, reaching about to the middle of the 
 supraanal plate and at base largely concealing it, apically narrowed 
 partly or wholly by their interior rounded emargination ; the cerci are 
 small, the apical portion subequal, nearly straight, and about half as 
 broad as the base; the subgenital plate is somewhat narrower than 
 long, subequal, apically extended slightly but not elevated, the lateral 
 margins straight and on a line with the upper side of the last abdomi- 
 nal segments, the apical margin well rounded as seen from above and 
 entire. 
 
 The species, six in number, are of medium or rather large size and 
 are found almost altogether in the southwest; only one is known east of 
 the Mississippi, .and that only in the neighborhood of the main stream.

 This species is very closely allied to the preceding, from which it 
 differs by its color and pattern, by the differently shaped male cerci and 
 furcula, by the extreme narrowness of the interspace between the 
 mesosternal lobes, and by the less sharply margined frontal costa.

 low, broad, subequal, the sides moderately narrow but low (male) or 
 scarcely sulcate (female); frontal costa broad, equal, plane (male) or 
 tumid (female) above, at and below the ocellus broadly and rather 
 deeply sulcate; eyes pretty large but not very prominent. Prouotum 
 with the prozona equal, the metazona expanding and punctato-rugulose; 
 median cariua slight but distinct on the metazoua, obsolete or subobso- 
 lete on the prozona; lateral carinae subobsolete; transverse sulci of 
 prozona slight but distinct, continuous. Tegmiua extending a very 
 little way beyond the abdomen, surpassing the hind femora. Supraanal 
 plate regularly clypeate, about as broad as long; plates of the furcula 
 shaped much as in M. bowditchi, but thickened at the tip, as long as 
 the cerci or nearly two-thirds as long as the supraanal plate; the cerci 
 have a triangular base and a long, straight, slender, bluntly terminated, 
 equal finger extending backward and upward and inclined inward, 
 starting from the lower posterior portion of the base; it is as long as 
 the terminal joint of the hind tarsi; subgenital plate scoop-shaped, 
 well rounded as viewed from above, the tip scarcely produced, entire. 
 
 The general color is greenish yellow, sometimes a little iufuscated 
 above, the head frequently mottled with fuscous; antennae uniform 
 yellowish; the usual stripe behind the eye over the upper portion of the 
 lateral lobes of the pronotum is generally reduced to a very narrow 
 dusky stripe next or on the lateral carinae, diminishing in breadth pos- 
 teriorly; or if it is broader, it sometimes invades the disk rather than 
 the lateral lobes; the disk has a median dusky line and the summit of 
 the head a dusky basal triangle. The tegmina partake of the general 
 lively tone to a less extent, and the paler median stripe, distinct only 
 at base, is seldom flecked intermittently with fuscous; hind femera yel- 
 low, the upper half of the outer face dusky, and two oblique dusky 
 patches often occur above; hind tibiae glaucous, the spines white or 
 glaucous, black tipped, ten to eleven in number in the outer series.

 McNeill found it in Illinois only on high sandy ground where the 
 sole vegetation was Cenchrus, and the grasshoppers were -'colored so 
 nearly like the yellow sand that they were difficult to see when only 
 two or three feet away." 
 
 A single specimen from Colorado which apparently belongs here, but 
 is too much injured to determine with certainty, has the hind tibiae 
 pale red.

 Long and slender bodied, warm brownish fuscous, sometimes more or 
 less ferruginous, with feeble markings. Head slightly prominent, dull 
 plumbeo-flavous, much obscured with fuscous, especially above and in 
 a band behind the eyes; vertex gently tumid, the interspace between 
 the eyes rather narrow, narrower than (male) or rather broad, broader

 excepting above, where it is seriately punctate next the margins; eyes 
 tolerably large, not very prominent, rather elongate; antennae slightly 
 shorter than (male) or about two-thirds as long as (female) the hind 
 femora, fulvo-luteous, infuscated apically. Prouotum gently enlarging 
 posteriorly, the front margin subtruncate, the hind margin somewhat 
 obtusely angulate, the angle well rounded, the disk nearly plane, pass- 
 ing by a rounded angle into the inferiorly vertical lateral lobes, the

 ble on the prozona; lateral lobes marked above more or less obscurely 
 with a broad fuscous stripe crossing the prozona, immediately below it 
 sometimes enlivened with paler flecks; prozona feebly longitudinal 
 (male) or feebly transverse (female), but little longer than the closely 
 and finely punctate metazona. Prosternal spine long, erect, conico- 
 cylindrical, blunt tipped ; interspace between inesosternal lobes several 
 times longer than broad, especially in the male, the metasternal lobes 
 attingent in part (male) or approximate (female). Tegmina very long 
 and slender, scarcely tapering, well rounded apically, feebly and very 
 minutely flecked, extending far beyond the femoral tips; wings ample,

 apically lutescent, pallid along the line of the spines, which are pallid 
 at base, black apically, and nine to eleven, usually ten, in number in 
 the outer series. Extremity of male abdomen a little clavate, upturned, 
 the supraaual plate subclypeate, with well rounded but feebly sinuate 
 lateral margins, which are broadly and feebly raised, and hardly the 
 least sign of a median sulcus ; furcula consisting of a pair of large, very 
 broad, much depressed, parallel plates, attingent at base, tapering 
 and bluntly rounded at tip, reaching-the middle of the supraanal plate,

 the inner apical angle sometimes feebly asserting itself as in the allied 
 species; cerci slender, not very long, incurved gently and a little 
 upcurved, tapering gently in less than the basal half, beyond cylindri- 
 cal, blunt tipped, reaching almost to the tip of the supraanal plate; 
 subgenital plate moderately broad, subequal, the lateral margins straight 
 but faintly rising at the apex, which is broadly rounded as seen from 
 above.

 This species differs from the two preceding by its slender elongate 
 form, the simplicity of its male furcula, and by its general markings. 
 
 4. GLAUCIPES SERIES. 
 
 The two species placed together here have comparatively little in 
 common to warrant their combination as a series, and each should 
 perhaps be made the basis of a distinct series if other forms are found 
 allied to one and the other; but falling together by the characters given 
 in our table, I have thought it best for the present to connect them. 
 They have these common characteristics: 
 
 The mesosternum in front of the lobes is plane in the male. The more 
 or less maculate tegmina extend only to the tip of the hind femora, and 
 the hind tibiae have from ten to twelve spines in the outer series. The 
 supraanal plate is simple, without elevated sides; the furcula is devel- 
 oped as a pair of minute triangular denticles; the cerci are broad and 
 short, only about twice as long as broad, a little upcurved, and apically 
 broadly rounded, while the subgenital plate is moderately broad, pro- 
 longed, and scarcely elevated apically. 
 
 The species are of small or medium size; one occurs in Texas and 
 northern Mexico, the other from Montana to Alaska.

 appearance; a broad black band extends from behind the eyes across 
 the upper part of the lateral lobes of the pronotirm, broadening on the 
 metazona. Interspace between the eyes moderately narrow, scarcely 
 wider than the first antennal joint; fastigium narrow, with sides 
 broadening a little in front, pretty sharply defined, inclosing a moder- 
 ately deep sulcus, deepest posteriorly ; frontal costa rather broad, nearly 
 equal, fading out below, with a scarcely perceptible sulcus excepting 
 about theocellus ; antennae a little more (male) or much less (female) than 
 three-fourths as long as the hind femora, orange red, paler at base. 
 Pronotum subequal, the disk nearly plane, the front border truncate, 
 the hind border obtusely angulate; median carina very slight, most 
 distinct on the metazona, cut by all the transverse sulci; lateral carinae 
 obsolete; prozona distinctly longitudinal, a third to a fourth longer 
 than the metazona (male) or quadrate, only slightly longer than the 
 metazona (female). Prosternal spine long, conical, bluntly tipped, some- 
 what retrorse, in the male considerably appressed ; interspace between 
 mesosternal lobes about twice as long as broad in both sexes, the meta- 
 sternal lobes attingent (male) or approximate (female). Tegmina as 
 long as the body, brown, with a few dusky flecks along the central 
 field. Legs darker or lighter brownish yellow, flecked with fuscous, 
 the hind femora bifasciate above with blackish, besides a blackish 
 base and apex ; hind tibiae glaucous with a pale annulus at the base, 
 interrupted in the middle by a blackish glaucous ring, the spines pallid 
 at base, black beyond, ten to twelve in number in the outer series. 
 Extremity of male abdomen compressed, hardly clavate, upturned, the 
 supraanal plate triangular with nearly straight sides, the surface sub- 
 tectate, with a very deep and narrow percurrent median sulcus, bounded 
 by sharp ridges; furcula consisting of a pair of basally attingent, 
 minute, triangular denticulations, surmounting the ridges of the supra- 
 anal plate; cerci broad at base, scarcely twice as long as broad, sub- 
 reniform, well rounded, but little smaller on the apical half, not so long 
 as the supraanal plate; subgenital plate broader than long, neither 
 elevated nor prolonged apically, but a little compressed, so that the 
 thickened apical margin as seen from above is strongly rounded (the 
 figure was, unfortunately, drawn from a specimen in which the extreme 
 apex was slightly collapsed in drying) and subacuminate, extending far 
 beyond the tip of the supraanal plate.

 insensibly into the lateral lobes on the prozona, but on the metazoua 
 with a distinct though rounded angle; prozona feebly (male) or dis- 
 tinctly (female) transverse, scarcely longer than the obscurely punctate 
 metazoua. Prosternal spine short, erect, conical, very blunt; interspace

 5. IJTAHENSIS SERIES. 
 
 In this small group the prozoua of the male is quadrate or subquad- 
 rate, and the interspace between the mesosterual lobes is as in the 
 spretus series; in front of these lobes, also, the mesosternurn of the 
 male has a central swelling forming a blunt tubercle. The antennae 
 are rather short and differ but little in the two sexes. The tegmina 
 are fully developed, but rather short, surpassing the hind femora but 
 little if at all, and clear or feebly maculate; the hind tibiae are red, 
 with normally eleven spines in the outer series. 
 
 The supraaual plate is rudely clypeate and longer than broad; the 
 furcula well developed, consisting of flattened, parallel, more or less 
 tapering fingers, half as long as the supraanal plate; the cerci are 
 laminate and simple, very broad and short, subequal, broadly rounded 
 apically, a little upcurved; the subgenital plate is peculiar, being* 
 exceptionally long and exceptionally broad, exceptionally elevated 
 and prolonged at apex, the apical margin strongly rounded and 
 mesially entire, though in one species laterally notched, an exceedingly 
 exceptional feature. 
 
 The species, three in number, vary from a little below the medium 
 to rather large sized. They are found mainly in the Cordilleran region 
 from about latitude 38 northward into Canada.

 plane with feebly raised margins between the eyes (female); frontal 
 costa broad, as broad as the interspace between the eyes, equal, or 
 feebly narrower above than below, just failing to reach the clypeal mar- 
 gin, feebly impressed at and sometimes a little below the ocellus, punc- 
 tate especially at the sides; eyes moderate, as long as the infraocular 
 portion of the genae, not very prominent; antennae varying from fulvo-

 angle into the sub vertical lateral lobes, the disk smooth, quadrate 
 (male) or feebly transverse (female), slightly longer than the finely and 
 densely punctate metazona, the transverse sulci distinct and continuous; 
 the upper two-fifths of the lateral lobes are marked on the prozona by 
 a fuscous or piceous patch, while the lower half is occasionally lighter 
 than the rest of the body. Prosternal spine erect, and moderately long, 
 appressed conical, the tip blunt (male) or short, stout, conico-cylin- 
 drical, very blunt (female); interspace between mesosternal lobes more 
 than twice as long as broad (male) or subquadrate (female) ; inetasternal 
 lobes attingent (male) or distant by half the width of the frontal costa 
 (female). Tegmina r< aching and generally somewhat surpassing the 
 tips of the hind femora, somewhat but rather delicately maculate in the 
 basal two-thirds of the discoidal area; wings pellucid, rather broad. 
 Hind femora fusco-fci ruginous, obliquely blotched externally and above 
 with luteo-testaceous, the lighter parts occurring before and past the 
 middle and as a pregenicular annulus; beneath dull luteous with a 
 tinge of fulvous; genicular arc fusco-piceous; inferior genicular lobe 
 pallid or sordid luteous with a basal black bar; hind tibiae pale red,

 fuscous patellar mark, the spines black excepting at base, ten to twelve, 
 usually eleven, in number in the outer series. Extremity of the male 
 abdomen a little clavate, much upturned, the supraanal plate rather 
 narrow, demi-oval, with rounded sides and scarcely angulate apex, the 
 rather deep median sulcus terminating beyond the middle by the con- 
 traction of its rather stout lateral walls, each lateral half of the plate 
 with a short apical ridge in its middle; furcula consisting of a pair of 
 straight, parallel, flattened, rather slender, tapering, pointed, basally 
 attiugent fingers, reaching the middle of the supraaual plate; cerci 
 broad, subequal but mesially contracted, compressed, slightly upcurved 
 and incurved laminae, bluntly rounded apieally, more than twice as 
 long as broad, shorter than the supraanal plate; infracercal plates 
 broad, obliquely truncate apically, scarcely surpassing the supraaiial 
 plate; subgenital plate greatly piolonged and elevated apically, the

 6. SPBETUS SERIES. 
 
 This group is a very homogeneous one and comprises the species of 
 Melanoplus which are especially destructive to vegetation by their 
 immense numbers and more or less extended flights, such destructive- 
 ness being almost confined to its members. The pronotuin of the male 
 is transverse or quadrate or feebly longitudinal, and the interspace 
 between the mesosternal lobes in the same sex varies from a little 
 longer than broad to fully twice as long as broad, the mesosternum in 
 front of the lobes centrally elevated to form a very low and blunt 
 conical tubercle or boss. The tegmina are always fully developed, 
 usually much surpassing the tips of the hind femora (though in one 
 case not nearly reaching them), more or less maculate (only immaculate 
 by individual exception), and the hind tibiae are variably colored, but 
 either red or green (very rarely blue or yellow), and have nine to 
 thirteen spines in the outer series. 
 
 The supraanal plate of the male is subtriangular, rather long, with 
 straight or sinuous lateral margins; the furcula consists of a pair of 
 slender, tapering, parallel or divergent, generally feebly depressed 
 fingers, generally extending over the basal fourth of the supraanal 
 plate; the cerci are rather broad and nearly straight and nearly flat 
 lamellae, the apical half narrower than the basal, generally through 
 oblique excision of the lower margin, and usually bent upward a little, 
 rounded or subtruncate at tip and from one and a half to three times 
 as long as broad; the subgenital plate is haustrate, about as broad as 
 long, more or less elevated apically and has the apical margin mesially 
 notched. 
 
 The species, seven in number, are of a medium or moderately large 
 size and range widely (especially M. atlanis, the range of which is 
 almost or quite equal to that of the group), occurring in every part of 
 the United States, from Atlantic to Pacific, excepting most of California 
 and the southernmost of the Atlantic States; members of the group 
 occur also, but apparently in scanty numbers, as far beyond our southern 
 borders as Central Mexico, and on the north, in full abundance, iu 
 Canada from ocean to ocean; but this group apparently does not 
 extend so far north as the femur-rubrum series, for it is not known 
 from Newfoundland or Labrador, nor about Hudson Bay, though in 
 the west it reaches the Arctic Circle, two of the species occurring in 
 Alaska.

 rowly subemarginate, hind margin obtusangulate; prozona longitudi- 
 nally quadrate (male) or feebly transverse (female), as long as the feebly 
 ruguloso-punctate metazona. Prosternal spine short, stout, appressed 
 cylindrical, very obtuse; interspace between mesosternal lobes more 
 than twice as long as broad, broadening posteriorly (male) or subquad- 
 rate (female). Tegmiua somewhat surpassing the tips of the hind 
 femora, moderately broad, distinctly tapering, rufo-fuscous, feebly mac- 
 ulate with black along the middle line. Fore and middle femora of 
 male rather strongly tumid; hind femora pale flavo-testaceous, necked 
 with black in open transverse fasciations on the upper half, at base, 
 just before, and somewhat behind the middle, the geniculation with the 
 base of the lower genicular lobe black, the outer half of the inferior 
 face roseate; hind tibiae dark or light red with a feeble fuscous patel- 
 lar spot, the spines black beyond the base, ten to twelve, usually eleven, 
 in number in the outer series. Extremity of male abdomen clavate,

 supraanal plate; cerci subfalcate, tapering more rapidly in basal than 
 in apical half, regularly curved upward, compressed, strongly rounded 
 apically, more than twice as long as median breadth; subgenital plate 
 pyramidal and strongly elevated apically, the apical margin much 
 thickened but notched by a deep mesial contraction, which separates 
 two rounded bosses.

 Bruner in an unpublished account of this species gives its habitat as 
 "in the mountains near Ogden,Utah, among the low trees and bushes, 
 at an elevation slightly above the highest of the ancient shore lines of 
 Salt Lake; also among the foothills of the Big Horn Mountains, near 
 Fort McKinney, Wyoming." 
 
 In the same manuscript, Bruner compares the present species with 
 M. atlanis, as follows : 
 
 Closely related to M. atlanis in many respects ; from which it is to be distinguished 
 by its somewhat larger size and more robust form, also by its larger head and more 
 prominent eyes. The last ventral segment [subgeuital plate] of the male is shorter 
 and the male cerci are narrower than in the typical atlanis. The color of the hind 
 tibiae is pale glaucous as in intermed'tus instead of red, as is usually the case in 
 typical specimens of atlanix.

 Mr. Bruner, in an unpublished account of this species kindly placed 
 in my hands, says that the point in Montana where this species was 
 taken is in the Yellowstone Valley above the mouth of the Big Horn 
 Eiver; and he gives the following points of difference between this 
 species and M. atlanis: 
 
 In intermedius the entire body is more or less covered with rather long fine hairs, 
 the thorax is much longer than in atlanis throwing the base of the posterior femora 
 considerably back of the middle and in this respect resembling Pezotettix [Mclano- 
 plu8~\ washing tonianus Bruner. The male cerci are longer and narrower than in 
 atlanis, and are curved slightly inward and upward on the apical half; they are also 
 shallowly grooved from the outside. The last ventral segment f subgenital plate] of 
 the male abdomen is a little shorter than in that species, and the prosternal spine is 
 also much longer, stouter, and more bluntly pointed than there. The general color- 
 ization is much the same as in atlanis but darker being dull brown and gray above 
 and dingy beneath; there are no well-defined bands upon the posterior femora, and 
 the tibiae are dull glaucous, more or less tinged with brown, especially on the basal 
 third and near the apex. 
 
 It differs from M. atlanis, to which it is most nearly allied, in the 
 longer male antennae, the weaker median carina of the pronotum, the 
 more heavily marked hind femora, and its smaller and slenderer form.

 This is the species which has been classed, in the National Museum 
 as belonging to Walker's Caloptenus scriptus, and is therefore prob- 
 ably the species so named by Cockerell 1 as coining- from Colorado. It 
 is, however, not that species, a female specimen of the present species 
 having at my request been compared with the types by Mr. S. Henshaw 
 during a recent visit in London. As compared with this, lie finds the 
 true scriptus to be u much larger, heavier, and with shorter, heavier, 
 and more clumsy prosternal spine; thoracic carinae, especially the 
 median, sharper and more prominent; cups of upper valves of ovipositor 
 much deeper; lower valves much heavier." He also compared this 
 with the type of Walker's Caloptenus lilituratm and found it the same, 
 "agreeing as to front, eyes, thoracic carinae, prosternal spine, and 
 inesosternal lobes." 
 
 This species varies somewhat, and runs very close indeed to M.atlani*; 
 more so in the northern examples from British Columbia and Wash- 
 ington than in those from Nevada; and were it not for the considera- 
 ble uniformity of Nevada specimens, in which the male cerci are always 
 relatively long and slender, and their marked distinction from Utah 
 specimens of M. atlanis, I should have hesitated to regard the species as 
 distinct from M. atlanis, especially in view of the great variation in the 
 latter species. As it is, I have been in much doubt where to place 
 females from British Columbia and Washington, where the two species 
 occur together.

 Varying from medium to a little above medium size, dark griseo-fus- 
 cous, often tinged more or less heavily with ferruginous. Head a little 
 prominent, olivaceo-testaceous freckled with fuscous, above more or less 
 jnfuscated, sometimes diffusing the whole, sometimes confined to two 
 divergent longitudinal stripes, with a broad, piceous, postocular band; 
 vertex rather tumid, somewhat elevated above the prouotum, the inter- 
 space between the eyes nearly twice as broad as the first antenna! joint 
 in both sexes; fastigium steeply declivent, shallowly sulcate, more shal- 
 lowly in the female than in the male; frontal costa rather prominent, 
 failing to reach the clypeus, feebly narrowed above especially in the 
 male, fully as broad as the interspace between the eyes, slightly sulcate 
 at and below the ocellus, irregularly punctate throughout, above more 
 densely and with a tendency to a biseriate arrangement; eyes moderate, 
 rather prominent particularly in the male, much longer than the infra- 
 ocular portion of the genae; antennae rufo- or luteo-testaceous, about 
 five-sixths (male) or three fifths (femal'e) as long as the hind femora. 
 Pronotum rather short, feebly and angularly constricted in the middle, 
 the broad angulation at the principal sulcus and produced mostly by 
 the posterior expansion of the metazoua, more or less iufuscated and 
 often also ferruginous above, the lateral lobes with a generally distinct 
 and entire but sometimes broken or maculate, broad, piceous, postocular 
 band, confined to the prozona ; disk broadly convex and passing into 
 the vertical lateral lobes somewhat abruptly but with a well-rounded 
 shoulder, simulating but nowhere really forming distinct lateral cariuae ; 
 median carina distinct and well marked on the metazoua, obscure and 
 generally subobsoleteon the prozouaif not indeed obsolete, particularly 
 between the sulci and in the female; front margin truncate but very 
 narrowly and minutely flaring, hind margin obtusangulate. the angle 
 very slightly rounded ; prozona subquadrate a little variable on either 
 side (male) or distinctly transverse (female), rarely and then feebly 
 longer than the densely punctate metazona. Prosternal spine variable, 
 usually short, conical, a little blunt, slightly appressed, erect (male) or

 short appressed subconical, very blunt, erect (female), but sometimes it 
 is very blunt and decidedly appressed in tbe male, also it is occasionally 
 distinctly transverse, but it usually snows a distinct taper, generally 
 from base to tip; interspace between mesosternal lobes varying from 
 quadrate to half as long again as broad (male) or from quadrate to 
 slightly longer than broad (female). Tegmina usually surpassing con- 
 siderably the hind femora, occasionally and especially in the female only 
 a little, slender, feebly tapering, brownish fuscous, nearly always flecked 
 lightly with fuscous throughout the discoidal area; wings rather broad, 
 hyaline, the veins mostly testaceous, growing increasingly fuscous 
 toward the margins, the apex sometimes most faintly, scarcely percepti- 
 bly, iufumate. Thoracic episterua mostly flavo-testaceous in contrast to 
 the fuscous surroundings. Fore and middle femora of male somewhat 
 tumid; hind femora luteo- or flavo-testaceous, obscurely broadly and 
 obliquely bifasciate with fuscous besides the fuscous base, the inner sur- 
 face mostly flavous, more or less clouded with fuscous, the lower surface 
 externally flushed with roseate, the geriiculation mostly fuscous; hind 
 tibiae normally rather bright red, often feebly pallescent at base, with a 
 faint fuscous patellar spot, but not infrequently pale red or pale green 
 or pale yellow, or even dark blue, the spines black beyond the base, 
 nine to twelve in number in the outer series. Extremity of male abdo- 
 men a-little clavate, a little recurved, the supraanal plate triangular 
 or hastate, feebly compressed just beyond the middle, the lateral mar- 
 gins before that a little elevated, the tip acutaugulate, the median 
 sulcus moderately deep, evanescent apically, its bounding ridges rather 
 high and followed apically by a pair of more distant longitudinal ridges 
 of less importance; furcula consisting of a pair of more or less diver- 
 gent, slight, slender, acuminate spines, less than a third, sometimes 
 only a fourth, the length of the supraanal plate; cerci generally about 
 twice as long as broad, sometimes less than that, rarely exceeding it, 
 composed of a basal, nearly equal, feebly tumid piece, and a strongly 
 compressed, slightly upturned and somewhat inbent apical portion, 
 narrowed by the oblique excision of the inferior margin, the apex well 
 rounded; subgenital plate subpyrainidal, with the apical margin a little 
 but rather abruptly elevated, thickened and mesially notched with 
 greater or less, generally considerable, distinctness, the notch followed 
 by a posterior sulcation to some distance.

 The published accounts add very little to the above range of distri- 
 bution, except that it is reported from Quebec (Provancher), northern 
 California (Packard), Nevada (Scudder), and south as far as middle 
 Florida probably by error (Packard). 
 
 It is probable, therefore, that it is found in every part of the continu- 
 ous district of the United States, excepting in the southernmost Atlantic 
 States and most of California, being thus limited very much as M.femnr- 
 rubrum ; it extends also into central Mexico, and north of our boundary 
 is found from Atlantic to Pacific as far at least as latitude 50 (except- 
 ing Newfoundland), and on the Pacific side reaches north to the Yukon 
 River and probably the Lower McKeuzie. 
 
 Next to M. spretus this is our most destructive locust, and east of 
 the Mississippi probably the only one ever doing much damage. Its 
 injuries, however, are not for a moment to be compared with those 
 inflicted by J/. spretus, for, though possessing good powers of flight 
 and on rare occasions known to migrate in swarms, its injuries can only 
 be classed as local, and they are never so serious as those inflicted by 
 M. spretus ; nevertheless they are by no means slight, and immense 
 destruction of grain is to be laid at its door. Bruner, who has studied 
 this insect over a wide extent of country, says that " while it occurs 
 over ... an extended territory, it appears to be ... partial to liilh

 or mountainous regions . . .5 it seems also to prefer a wooded or mixed 
 country to the open prairies or plains." 
 
 This is one of the most variable of the Melanopli, and it is some- 
 times difficult to distinguish from its immediate allies. The above 
 description is drawn up primarily from Eastern examples which came 
 from the region from which the species was originally described. 
 Specimens from the dry plains of the West (especially noted in those 
 from Utah) are decidedly paler and more cinereous in aspect than those 
 from relatively fertile country, and they have often a flavous stripe 
 bordering the eye and continued along the position of the lateral 
 carinae: a similar but not so striking a cinereous hue attaches to those 
 tliat occur in sandy localities in the Eastern States, as along the sea 
 margin. The exact contrary is shown in Canada just east of the Eocky 
 Mountains, where the specimens are exceedingly dark in color, almost 
 blackish fuscous, with heavy fasciation of the hind femora; l but here 
 again a difference of another sort occurs as one passes eastward, speci- 
 mens from Laggan and Banff almost invariably having relatively long 
 and slender male cerci, while at Calgary all that have been seen (with 
 a very few from the former localities) have male cerci hardly more 
 than half as long again as broad. Specimens from Mexico, however, 
 agree very closely with those from New England. 
 
 Specimens with green hind tibiae have been seen by me from the 
 White Mountains, New Hampshire, but not from the summits (except 
 Kearsarge 3,251 feet), from the vicinity of Boston, at Provincetown, 
 and on the island of Nantucket, Massachusetts, from Laggan, Alberta, 
 the Yellowstone region, Montana, Wyoming, Nebraska, Missouri, Colo- 
 rado, from the Salt Lake valley and American Fork Canyon (9,500 feet), 
 Utah, Texas, and Chihuahua, Mexico. Specimens with dark blue 
 hind tibiae have been seen from Iowa, Colorado, American Fork Canyon, 
 Utah, and Texas. In nearly or quite all these cases specimens with 
 red hind tibiae predominated in the same district. 
 
 According to Kiley the first mature insects observed one year about 
 St. Louis, Missouri, appeared July 12, and deposited eggs by July 20. 
 The eggs had a quadrilinear arrangement in the pod, hatched in from 
 three to four weeks, and the young took eighty days to reach maturity. 
 He says he has proved that the insect is there double-brooded, though 
 I find no data published by him in support of the statement, and the 
 above facts drawn from his writings militate against it. Bruuer, how- 
 ever, agrees with it, saying that in the District of Columbia a second 
 brood appears in the late autumn, composed of smaller and darker 
 individuals. I have seen nothing of the kind in New England. 
 
 The points in which the unfledged locusts differ from the same stages 
 in M. spretus and M. femur-rubrum are explained and figured in the 
 first report of the United States Entomological Commission, in which 
 many other interesting points regarding this species will be found.

 Head somewbat prominent, light fusco-olivaceous, with a broad, 
 piceous, postocular band, and above more or less infuscated or dulled 
 in color, often with a pair of longitudinal fuscous stripes; vertex rather 
 tumid, raised considerably above the level of the pronotum, the inter- 
 space between the eyes half as broad again (male) or fully twice as 
 broad (female) as the first anteunal joint; fasti giuni steeply declivent, 
 rather deeply (male) or shallowly (female) sulcate throughout; frontal 
 costa moderately prominent, distinctly failing to reach the clypeus, 
 slightly narrowed above, especially in the male, about as broad as the 
 interspace between the eyes, feebly and broadly sulcate at and below 
 the ocellus, feebly punctate, above biseriately; eyes not very large 
 nor very prominent, not more so in the male than in the female (unus- 
 ual in Melanoplus), slightly shorter than the infraocular portion of the 
 genae ; antennae testaceous, nearly two-thirds as long as the hind femora 
 in both sexes, scarcely relatively shorter in the female than in the male. 
 Pronotum very short, equal on the prozona, expanding somewhat on 
 the metazona, light brownish fuscous, often ferruginous, the lateral 
 lobes with a much broken and maculate postocular piceous or dark 
 fuscous band confined to the prozona, the disk broadly convex, passing 
 into the vertical lateral lobes by a rounded angle forming a blunt 
 shoulder on the metazona and posterior section of the prozona only; 
 median cariua distinct and antero-posteriorly convex on the metazona, 
 feeble and often subobsolete on the prozona; front margin truncate, 
 hind margin feebly obtusangulate, the angle sometimes rounded; pro- 
 zona distinctly transverse, more so in the female than in the male, 
 shorter (particularly in the female) than the finely and very feebly 
 punctate metazona. Prosternal spine rather long, appressed, feebly 
 conical, very blunt, erect, shorter in the female than in the male; inter- 
 space between mesosternal lobes from half as long again to twice as

 hyaline, the veins mostly fuscous, but testaceous next the costal margin. 
 Fore and middle femora only a little tumid in the male; hind femora 
 testaceo-ferruginous clouded with fuscous above, particularly in broad 
 basal, premedian and postmedian patches, the geniculation mostly 
 blackish fuscous, the lower genicular lobe pallid testaceous with a basal 
 blackish bar, the inferior surface, especially externally, flushed with 
 roseate; hind tibiae bright red throughout, the spines black almost to 
 the very base, ten to eleven, rarely twelve, in number in the outer series. 
 Extremity of male abdomen a little clavate, somewhat recurved, the 
 supraanal plate triangular or subhastate, faintly compressed just 
 beyond the middle, the margins feebly elevated on basal half, the apex 
 subacutangulate, the median carinapercurrent and rather deep, bet ween

 female, 8.75 mm.; tegmiua, male, 26.5 mm., female, 27.5 mm.; hind 
 femora, male and female, 14 mm. 
 
 Two hundred and seventy- six males, 439 females. I refrain from givin g 
 in detail the localities from which I have seen specimens, both on account 
 of their immber and because, from the irregular distribution of the 
 insect in different years, such details would have little value without 
 dates, which are not always accessible; farther on, however, I give all 
 that are of special interest. 
 
 The name of this species is to be credited to Mr. P. R. Uhler, who 
 placed it in his collection thirty or more years ago and communicated 
 it to various persons, who used it. sometimes in an incorrect form. The 
 original specimens were received from Mr. Robert Kennicott, and were 
 obtained by him from a migratory horde which settled in the then Red 
 River settlements, now Winnipeg and vicinity, Manitoba. On Mi\ 
 Uhler's generous transfer of his collection to me, these specimens, with 
 their history, came into my possession, and I now have them with his 
 original labels. One has been placed in the National Museum. 
 
 It was thus known from the start as a migratory insect, and com- 
 paring it with any species of the genus one would at once be struck 
 with the greater length of the tegmiua and wings. These were meas- 
 ured by Riley; in forty-eight males the tegmiua extended beyond the 
 abdomen 5 to 10 mm., with an average of 7.6 mm. ; in ninety-nine females 
 they ranged from 3 to 10 mm. beyond the abdomen, the average 6.7 mm. 
 
 It is now well known as the "Rocky Mountain Locust" or destructive 
 locust of the States in the western half of the Mississippi Valley. It 
 has been more written about than any other American Orthopteroii, and 
 was specially discussed by the United States Entomological Commission, 
 organized to devise methods of checking its ravages after a study of its 
 natural history. It forms the almost exclusive subject of their first 
 report, and occupies a considerable space in their second. Although a 
 considerable body of the evidence adduced by them is contradictory 
 and in part of doubtful application to this particular species, their con- 
 el tisio;iis are in very large measure well founded. As appears from a 
 study of their work and other available material, the following conclu- 
 sions may be fairly drawn: 
 
 (1) Tho home of the species is in favorable localities in the elevated 
 region of the Rocky Mountains or immediately bordering it from the 
 
188 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL.XX. 
 
 South Saskatchewan to Wyoming, inclusive, and in the Bocky Moun- 
 tain region proper in Colorado and Utah. 
 
 (2) In certain years, especially in dry seasons, between raid- July and' 
 mid-September, migratory hordes of incredible numbers and of both 
 sexes pass from their natural breeding grounds to the east, southeast, 
 and south, conveyed by the winds (toward which they head) over a 
 greater or less and sometimes a vast extent of country from Lake Win- 
 nipeg to or almost to the Gulf of Mexico, rarely passing farther east 
 tban longitude 93, and devastating the countries they reach to an 
 alarming extent, sometimes in places absolutely destroying all standing 
 crops and defoliating fruit trees. 
 
 (3) As they rise for flight from home only in dry clear weather (when 
 the prevailing winds are from the north or northwest), they do not seri- 
 ously invade the regions (mostly infertile) to the west of their home. 
 
 (4) The invaders extend or may extend their flights to a distance ofi 
 at least 500 miles from their point of origin, but there is no clear evi- 
 dence to show that (as claimed by the Commission) they extend it to 
 double that distance. 
 
 (5) They deposit their eggs throughout the invaded territory, but 
 their descendants therein of the succeeding year not only do not effect 
 a tithe of the damage of the preceding year (although on the ground 
 earlier), but when winged move about in swarms from place to place, 
 their prevailing direction at least during the earlier part of the sea- 
 son being the reverse of that of their parents; but even when they 
 alight and cover the ground they are far less harmful than were their 
 invading parents. 
 
 (6) With few exceptions, movements on the wing are with or nearly 
 with the wind, and are usually made in clear weather between 9 a. m. 
 and 4 p. m., but they are sometimes certainly made at night. 
 
 (7) Eelatively speaking, exceedingly few of the returning swarms 
 ever reach the true home of the species. As a rule, they show signs of 
 enfeeblement and deposit few eggs in the invaded region, so that their 
 descendants on the invaded soil grow less and less numerous, and, in 
 effect if not in fact, die out in the course of a very few, probably at 
 most two or three, years. 
 
 1 can add almost nothing to the facts given by the Entomological 
 Commission. It may be worth while to state that in 1877 I took or 
 noted this insect at the following points: July 11, between Idaho and 
 Georgetown, Colorado, common, both mature and immature; July 12-13, 
 Georgetown, Colorado, from 8,500 feet to above timber, mature and 
 immature; July 16, Argentine Pass, Colorado, 13,000 feet, in abundance, 
 from young just hatched to imagos, and masses of dead imagos under 
 stones on the mountain crests; July 20, Laramie, Wyoming; July 
 21-31, Green River, Wyoming, plenty but not abundant and mostly 
 mature; Alkali Station, north of Green River, Wyoming, 6,000 feet; 
 August 1-4, Salt Lake Valley, mostly mature, very plenty everywhere

 but particularly in the southern end of the valley; August 2-3, Amer- 
 ican Fork Canyon, Utah, 9,500 feet; August 6, Evanston, Wyoming, 
 6,800 feet, plenty; August 11-16, South Park, Colorado, 8,000 to 10,000 
 feet, everywhere, mature; August 13, Mount Lincoln, Colorado, 11,000 
 to 13,000 feet, crowds of nymphs and images, as well as masses of dead 
 imagos under stones at summit; August 17-22, Florissant, Colorado, 
 8,000 feet; August 24, Pikes Peak, Colorado, 12,000 to 13,000 feet; 
 August 24-25, Manitou, Colorado, 6,300 feet; August 26, Colorado 
 Springs, Colorado, plenty; August 28-29, Garland, Colorado, 8,000 
 feet, plenty ; August 29, Sierra Blauca, Colorado, below 10,000 feet, none 
 seen above timber; August 30-31, Pueblo, Colorado, 4,700 feet, plenty; 
 August 31, Animas, Colorado; September 1, Lakin, Kansas, plenty. 
 
 I have also seen specimens from the following localities, which have 
 some special interest: Fort Hayes, Kansas, collected by J. A. Allen in 
 June, 1871 (not heretofore reported in Kansas in this year); Preston, 
 Texas, Captain Pope, May 15, 1854 (necessarily the progeny of an invad- 
 in-g flight in a previous year, and none are recorded either in Texas or 
 Arkansas between 1850 and 1853, inclusive); Binggold Barracks, on 
 the Lower Eio Grande, A. Schott, presumably also in the spring of 
 1854, when the Mexican Boundary Commission was at work there; 
 Sonora, Mexico, A. Schott, and San Lorenzo, Chihuahua, Mexico, E. 
 Palmer, showing that it reaches Mexico, and that too even as far west 
 as Sonora. I have also a single specimen from California from Mr. H. 
 Edwards, but it may have been taken in that part of the State east of 
 the Sierra Nevada. 
 
 A tabular view of " locust years " for the different States will be 
 found in the first report of the Commission, page 113. 
 
 This insect is normally single brooded; the eggs winter and the 
 earliest (those in warm exposures) hatch in Texas from the middle to 
 the last of March, and " continue to hatch most numerously about four 
 days later with each degree of latitude north," so that in Montana and 
 Manitoba it is from the middle of May to the first of June. This is in 
 the temporary region ; probably it is correspondingly later on the higher 
 levels of the permanent breeding grounds. The young reach maturity 
 in sixty to seventy- two days, to judge from those reared in confine- 
 ment, and after a few days couple, the female beginning to lay eggs in 
 about a fortnight thereafter. The eggs arc laid in almost any kind of 
 soil, but by preference in bare, sandy places, and in their permanent 
 home they show a preference for the shaded base of shrubby plants; 
 they are laid in a sort of pod, with a quadrilinear arrangement therein. 
 Several pods may be laid by a single female, Mr. Eiley having on 
 three different occasions obtained two pods from single females in con- 
 finement, laid at intervals of eighteen, twenty-one, and twenty-six days, 
 respectively. 
 
 The migratory instinct appears to be strongest within about three 
 weeks from the time of attaining maturity, or shortly before and during

 the season of oviposition. The return flights in the " temporary region" 
 begin from the 5th to the 10th of May in latitude 35, and about four 
 days later with each degree farther north. Mr. Riley, from whose 
 accounts these statements are drawn, gives a long list of plants and 
 trees attacked by this locust and its preferences among them. 1 
 
 7. DEVASTATOR SERIES. 
 
 This group is composed of very closely related species, often difficult 
 to distinguish, in which the male prozona is quadrate or subquadrate, 
 and the immature markings on the lateral lobes of the pronotuin, char- 
 acteristic of the young of Melanoplus, occasionally persist in the adult 
 -and especially in the female; the interspace between the mesosternal 
 lobes of the male is always longer than broad, varying from a little more 
 than half as long again to a little more than twice as long as broad. 
 The tegmina are always fully developed and generally maculate; the 
 hind tibiae are variable in color, often within the species, and have 
 from nine to thirteen spines in the outer series. 
 
 The supraanal plate is similar to that of the femur-rubrum series, 
 but less constricted in the middle and shorter; the furcula consists of 
 a pair of parallel or subparalleJ, tapering, tolerably long, generally 
 fattened, acuminate fingers; the cerci are very simple, rather small, 
 not reaching the tip of the supraanal plate, slender and subequal, 
 tapering feebly in the basal half, equal beyond, bluntly rounded at tip, 
 and a little incurved, generally slightly sulcate or dimpled apically on 
 the outer side; the subgenital plate is broad, of subequal breadth, but 
 slightly broader at base than at tip, apically elevated and the apical 
 margin well rounded, thickened, and weakly notched. 
 
 The insects are of small or medium size, and the species, eight in 
 number, are separable with difficulty. They are confined almost 
 exclusively to California, a single one of them only occurring also a 
 little beyond its boundaries in the neighboring regions. It is the char- 
 acteristic group of the Pacific coast.

 This species is very closely related to the last, and with larger 
 material may prove to be the same: but the anal cerci are faintly larger

 only moderately slender, tapering a little, well rounded apically, fus- 
 cous, generally very dark fuscous, the discoidal area maculate in a very

 The species has also been reported from various other counties in 
 California, mostly in the central portions of the State, such as Fresno, 
 Yuba, Napa (Riley), Sutter, San Joaquin (Coquillett), and Lake Tahoe, 
 Placer County (Scudder), as well as from districts immediately adjoin- 
 ing California, as the adjacent parts of Oregon (Bruner), Keno, Washoe 
 County, and Glen Brook, Douglas County, Nevada (Scudder), and Ari- 
 zona (Bruner). 
 
 It has also been stated to occur in Colorado (Scudder), Kansas, North 
 Dakota, northwest Wyoming, and Montana (Bruner), Idaho (Bruuer, 
 Milliken), and in Utah in the Salt Lake Valley (Scudder) and Nephi, 
 Juab County (Eiley); but certainly in some, and probably in all these 
 cases, the insect reported was mistakenly supposed to be this species. 
 
 Coquillett describes a dipterous parasite, Sarcophaga opifera, as found 
 in this species, and gives in the Twenty-seventh Bulletin of the Ento- 
 mological Bureau at Washington a full account of the ravages of this 
 locust in California, where they appear to do most damage to vineyards 
 and to deciduous fruit trees, the latter of which always suffer the most 
 in the vicinity of grain fields, upon which the migrating swarms appear 
 always to descend, attracted, perhaps, by their color. Grain, however, 
 appears to suffer relatively little at their hands, though alfalfa proves 
 attractive. 
 
 A description of the colors of the living young, by Mr. Coquillett, 
 will be found in the report of the United States Entomologist for 1885, 
 page 293. 
 
 The species is an exceedingly variable one, and with limited material 
 it would be difficult to believe that there was but a single species, so 
 widely different is the appearance of the extremes. This, I suspect, 
 will prove partly dependent upon station, though the different forms 
 into which I would provisionally separate the species appear to be 
 found indifferently in almost all parts of the State, though, as far as the 
 collections before me show, all appear to be more abundant in the cen- 
 tral and northern portions. 
 
 There is first the dark and rather small form, which is prevalent 
 about San Francisco, and which may be called M. d. obscurus (Plate 
 XIII, figs. 3, 4). It is also found in Sierra, Placer, Mariu, Sacramento, 
 Eldorado, and Alameda counties, as well as in Siskiyou County, in the 
 
NO. 1124. REVISION OF THE MELANOPL1 SC UDDER. 199 
 
 north, and Los Angeles County, in the south. The typical forms are 
 very dark, having tegmina surpassing but little the hind femora, with 
 meager maculation of the discoidal area, rarely at all cinereous in the 
 basal half ; the hind tibiae are variable in color. 
 
 A second form, which appears to be the widest spread, occurring in 
 nearly every county in which the species has been found, from Shasta 
 to San Diego and from Marin to Sierra, is of a decidedly cinereous 
 aspect, with abundant and generally rather confused maculation in the 
 discoidal area of the tegmina, which usually much surpass the hind 
 femora; the hind tibiae are variable, but rarely glaucous. This form 
 best represents the original types of the species when first described, 
 and being also the most common may bear the name M. d. typicalis 
 (Plate XIII, fig. 5). It is of medium size. 
 
 The third form is also of medium size and is very closely related to 
 the last, and often hardly distinguishable. It may be called -If. rf. 
 affinis 1 (Plate XIII, fig. 6). It differs principally by its shorter teg- 
 mina, which rarely surpass the hind femora, and which are very sharply 
 maculate, with well-defined spots, and the hind tibiae are usually glau- 
 cous, occasionally luteous. I have seen specimens from Sierra, Sacra- 
 mento, and Los Angeles counties. 
 
 The fourth form is by far the largest and the most heavily marked of 
 all, besides being of a rather light tint, in which the dark maculations 
 appear with the greater distinctness, and it may accordingly be known 
 as M. d. conspicum (Plate XIII, fig. 7). It appears much like an exag- 
 gerated form of the last-mentioned type, and has a more prominent 
 head, much longer tegmina, which well surpass the hind femora, and 
 ample wings, so that I suspect the migrating flights will be found to be 
 composed mainly or exclusively of this form ; the pronotum is unusually 
 clear of lateral markings, and the hind tibiae are pale glaucous. It has 
 not been found south of the center of the State (nor have any migratory 
 hordes been reported there), and indeed only in the central portions 
 and the elevated districts, namely, in Sacramento, Eldorado, Ainador, 
 and Merced counties.

 8. IMPUDICUS SERIES. 
 
 This group is composed of a single species of medium size, and is more 
 nearly related to the next group than to any other. The prozona is 
 slightly longitudinal in the male. The interspace between the ineso- 
 sternal lobes in the same sex is nearly half as long again as broad and 
 the metasternal lobes are only approximate. The tegmina are fully 
 developed and surpass the hind femora. The hind tibiae are red and 
 have eleven to thirteen spines in the outer series. 
 
204 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL.XX. 
 
 The supraanal plate is regularly triangular with straight sides and 
 acutangulate apex, the surface entirely in the same plane from base to 
 apex, i. e.,with no apical depression. The furcula in the single known 
 species is reduced to a pair of very slight rather distant spines, no 
 longer than the last dorsal segment. The cerci taper considerably at 
 base, but more by excision of the lower than of the upper margin, and 
 beyond the middle are subequal, hardly in the least incurved, and api- 
 cally angulate. The subgenital plate is of equal breadth throughout 
 and terminates in a postmarginal blunt tubercle above, the apical mar- 
 gin being abbreviated, rounded, and entire. 
 
 The single species occurs in the Southern States, east of the Missis- 
 sippi.

 Of medium size, brownish fuscous, with a decided ferruginous tinge. 
 Head moderately prominent, testaceous or ferrugineo-testaceous, dotted 
 above with fuscous, the dots mesially forming a stripe, and with a dis- 
 tinct postocular piceous band; vertex rather tumid, distinctly elevated 
 above the pronotum, the interspace between the eyes as broad (male) 
 or fully half as broad again (female) as the first antennal joint; fas- 
 tigium steeply declivent, feebly (male) or very feebly (female) sulcate; 
 face more than usually retreating, the frontal costa failing to reach the 
 clypeus, equal, as broad (male) or almost as broad (female) as the inter- 
 space between the eyes, sulcate excepting above where it is biseriately 
 punctate; eyes not very prominent, rather large, distinctly longer than 
 the infraocular portion of the genae; antennae ferruginous, less than 
 two-thirds (male) or about three-fifths (female) as long as the hind 
 femora. Pronotum subequal, expanding a little on the metazona, the 
 disk ferrugineo-luteous necked with fuscous, very feebly convex, pass- 
 ing by a rounded shoulder nowhere forming lateral carinae into the 
 anteriorly tumid vertical lateral lobes, which are of the color of the 
 face, with a broad piceous postocular stripe across the prozona; median 
 carina distinct on the metazona, feeble and in the female subobsolete 
 on the prozona; front margin truncate; hind margin obtusangulate; 
 prozona feebly longitudinal (male) or distinctly transverse (female), a 
 little (male) or no (female) longer than the delicately punctate meta- 
 zona. Prosternal spine rather long (male) or rather short (female), 
 conical, rather blunt, suberect; interspace between mesosternal lobes 
 nearly half as long again as broad in both sexes, the inetasternal 
 lobes approximate (male) or somewhat approximate (female). Tegmina 
 surpassing a little (male) or considerably (female) the hind femora, 
 moderately broad, tapering (more rapidly in the male than in the female), 
 brownish fuscous, the discoidal area lighter at least on the basal half, 
 and necked throughout with tolerably large, more or less rounded, dark 
 fuscous spots ; wings rather broad, hyaline at base, beyond infumated

 somewhat tumid in the male; hind femora ferruginous or ferrugiueo- 
 testaceous, obliquely bifasciate with blackish fuscous excepting below, 
 the under face lighter or deeper orange, the whole geniculation infus- 
 cated; hind tibiae bright red, the spines black excepting at base, eleven 
 to thirteen in the outer series. Extremity of male abdomen a little 
 clavate, slightly recurved, the supraaual plate triangular with straight, 
 scarcely and narrowly elevated margins, acutangulate apex, the median 
 sulcus confined to the basal half, tapering, narrow, and very deep, 
 between high and sharp walls, which unite in the middle of the plate; 
 furcula consisting of a pair of slight, brief, parallel, moderately distant 
 spines lying upon the bases of the ridges of the supraanal plate; cerci 
 small compressed laminae, tapering rapidly in the basal half and more 
 rapidly beneath than above, beyond equal and about half as broad as 
 extreme base, apically rounded angulate, nowhere incurved, scarcely 
 so long as the supraanal plate; infracercal plates very broad at base, 
 extending far outside the cerci, rapidly narrowing with straight mar- 
 gins, distinctly shorter than the supraanal plate; subgenital plate

 9. ABLDUS SERIES. 
 
 In this group the antennae of the male are exceptionally long and the 
 prozona is distinctly longitudinal. The interspace between the ineso- 
 sternal lobes in the same sex varies from subquadrate to half as long 
 again as broad, while in the female it varies from distinctly transverse 
 to much longer than broad. The pronotum is posteriorly truncate or 
 subtruncate, usually broadly emarginate. The tegmina are not only 
 abbreviate but rarely as long as the pronotum, lateral and distant. 
 The hind femora are long, and the hind tibiae light colored, with eight 
 to twelve, generally about ten, spines in the outer series. 
 
 The supraanal plate of the male is triangular and rather simple; the 
 last dorsal segment is obliquely and deeply sulcate on either side of the 
 base of the furcula, which consists of a pair of very slender parallel 
 fingers or spines of variable length, but never very long; the cerci 
 rapidly narrow at the base to a long and exceedingly slender incurved 
 blade, hardly as long as the supraanal plate, and narrower by far than

 The only specimen seen has been in alcohol and the colors are more 
 or less bleached; it is brownish testaceous, marked with black. Head 
 large, somewhat protuberant, without markings except a slender black 
 line behind the eye ; vertex somewhat tumid and a little elevated above 
 the pronotum, sharply punctate except in a posteriorly broadening 
 mesial band which was probably darker colored, the interspace between 
 theeyes much broader (a little distorted in the specimen) than the first 
 an tennal joint ; fastigium rather steeply declivent, rather narrow, sul- 
 cate, biseriately punctate; frontal costa rather prominent above, fading 
 before theclypeus, much broader than the interspace between the eyes, 
 equal, sjiallowly sulcate excepting above, sparsely punctate; eyes of 
 moderate size, not prominent, about as long as the iufraocular portion 
 of the genae; antennae testaceous, apically infuscated, less than two- 
 thirds (female) as long as the hind femora. Pronotum very regularly 
 and feebly enlarging posteriorly, the upper half of the lateral lobes of 
 the prozona with a very large, posteriorly narrowing, piceous patch, 
 nearly split in two subequal portions by a wedge of the basal color 
 extending obliquely upward from the lower anterior corner, and nar- 
 rowly edged above on the disk by a pallid tint; disk transversely con- 
 vex, passing by a very rounded and scarcely perceptible angle into the 
 very steeply declivent and inferiorly vertical lateral lobes, with no lateral 
 carinae; median carina percurrent, feeble on the metazona, coarse and 
 rather prominent on the prozona; front margin truncate but feebly and 
 narrowly flaring; hind margin roundly, broadly and feebly emarginate; 
 disk of prozona very coarsely punctate, quadrate, fully a third as long 
 again as the strongly transverse, finely punctate metazona. Prosternal 
 spine short, conical, blunt; interspace between mesosternal lobes 
 (female) distinctly transverse, narrower than the lobes. Tegmina 
 abbreviate, shorter than the pronotum, lateral, widely separated, 
 enlarging from the base to the middle, beyond equal, apically rounded, 
 several times longer than broad, black on ground with testaceous veins. 
 Hind femora brownish testaceous on upper half, its lower limit infus- 
 cated on the outer face, pallid on lower half, the genicular arc black ; 
 hind tibiae pale testaceous, the spines black tipped, nine to ten in num- 
 ber in the outer series. Supraanal plate of male "bicarinate longitudi-

 One female. Arizona, G. W. Dunn (L. Bruner). It was originally 
 described from southern Arizona. 
 
 I have here adhered to iny original limitation 1 of Thomas's species, 
 although I was mistaken in supposing that the male I then had before 
 me was one of those used by him in his description, since he describes 
 the cerci as enlarged at the extremity, which they certainly were not 
 in the one then in my hands. Thomas's originals, so far as now pre- 
 served in the National Museum, all belong to my Mel. aridus, but for- 
 tunately a specimen in Professor Bruner's collection, although it is 
 only a female, enables me to fix the species. It may be separated from 
 Mel. aridus by the character which Thomas describes thus: "Posterior 
 margin [of pronotuin] truncate on the back [i. e., disk], or curved 
 slightly forward" [i. e., emarginate], the posterior margin in Mel aridus 
 being distinctly obtusangulate, though subtruncate.

 Pale brown suffused with flavous and marked with black. Head 
 not prominent, or in the male scarcely prominent, pale flavo-testaceous 
 heavily mottled with brown, above almost wholly brown, with a broad 
 postocular piceous band margined with flavous (these markings not 
 seen in the female) ; vertex tumid, distinctly elevated above the pro- 
 notum (male) or feebly tumid, not thus elevated (female), the interspace 
 between the eyes nearly half as broad again as the first antenna! joint; 
 fastigium rather strongly declivent, deeply (male) or feebly (female) sul- 
 cate; frontal costa subequal, but slightly expanded at the ocellus, where 
 it is equal to (male) or broader than (female) the interspace between the 
 eyes, sulcate distinctly and throughout (male) or feebly and at and a 
 little below the ocellus (female) ; eyes rather large and rather prominent 
 especially in the male, elongate, very much longer than the infraocular 
 portion of the genae; antennae flavous, a little shorter than (male) or 
 about two-thirds as long as (female) the hind femora. Pronotuni sub- 
 equal on the prozona, expanding on the metazona, nearly uniform in 
 coloring except for a large flavous-margined, piceous, postocular patch 
 crossing the prozona, more or less broken and irregular in the female; 
 disk pretty strongly convex, passing almost insensibly into the lateral 
 lobes with no trace of lateral carinae, though the position of these is

 zona than on the metazona; front margin subtruncate, feebly and nar- 
 rowly flaring in the male, hind margin broadly and roundly but not 
 deeply einarginate; prozona punctate next the front margin, distinctly 
 longitudinal (male) or quadrate (female), mesially twice as long (male) or

 sternal spine appressed conical and slightly retrorse (male) or erect, 
 conical (female), rather long and slender ; interspace between mesosternal 
 lobes transversely subquadrate (male) or a little transverse (female), the 
 metasternal lobes subattingent (male) or somewhat approximate 
 (female). Tegmina about as long as the prozona, elliptical, about three 
 times as long as broad, broadly rounded at tip, lateral, widely distant, 
 black with testaceous veins. Fore and middle femora somewhat en- 
 larged especially in depth in the male ; hind femora flavous, more or 
 less longitudinally infuscated or ferruginous, especially on or next the 
 carinae, the genicular arc piceous, the lower genicular lobe wholly pallid ; 
 hind tibiae pale dull flavous, delicately mottled with ferruginous, the 
 spines black excepting at base, eight (female) or ten (male) in number 
 in the outer series. Abdomen feebly carinate, nearly uniform in color, 
 the extremity subclavate in the male, a little recurved, the supraanal 
 plate triangular, roundly acutaugulate at tip, the surface vaulted, with 
 a large subbasal rounded basin taking the place of the usual median 
 sulcus, and into which falls the furcula, consisting of a pair of very 
 slender, parallel and adjacent, subequal, cylindrical fingers, extending 
 less than a third the distance across the plate; cerci slender, gradually 
 incurved but otherwise straight, compressed blades, tapering at the 
 very base, but beyond subequal, rounded at tip, considerably shorter 
 than the supraanal plate; subgeuital plate small, subpyrarnidal, of 
 about equal breadth and length, the margin apically angulate, entire.

 One male, 1 female. Tepic, Jalisco, Mexico, November, Coll. Calif. 
 Acad. Sc. (L. Bruner) ; Cape St. Lucas, Lower California ( ?), J. Xautus. 
 
 The female, collected by Xantus (presumably at Cape St. Lucas), is 
 the one referred to by me in my original description of M. aridus as 
 belonging to that species, but it differs from it (and agrees with M. 
 ImmpJireysU] in the emargiuation of the posterior border of the pro- 
 notum, and differs from both in the greater robustness of the body, 
 especially in the metathoracic region. It is quite possible that the 
 male and female here brought together do not properly belong to one 
 species; there is great disparity in size and, as the description shows, 
 some unusual disagreements between sexes of the same species; but 
 they certainly belong in close proximity, even if distinct; if they should 
 prove distinct, the name should be retained for the male, from which 
 the description (especially in colors) has principally been drawn.

 tinctly longer than (male) the infraocular portion of the genae; 
 antennae tiavo-testaceous, about five-sixths (male) or two thirds 
 (female) as long as the hind femora. Pronotum simple, expanding a 
 very little posteriorly, the prozona slightly swollen on the upper part 
 of the lateral lobes, into which the disk passes insensibly; there is a 
 broad black band at the upper limit of the lateral lobes of the pro- 
 zona, which either narrows on the metazona so as only to edge the 
 lower side of the position of the lateral cariuae, or, if of equal width 
 with the preceding portion, is enlivened by a yellow stripe passing 
 longitudinally through the middle, a continuation of the black bordered 
 yellowish stripe on the metathoracic epipleura; occasionally the band 
 is wholly obsolete on the metazona; in the middle of the portion of 
 the band on the prozona is also a roundish or oblique pyriform yellowish 
 spot; median cariua distinct, equal, but low and rounded ; front margin

 10. INDIGENS SEEIES. 
 
 In this group, consisting of only a single species of medium size, the 
 prozona of the male is very longitudinal and the interspace between 
 the mesosternal lobes of the same sex only slightly longer than broad. 
 The antennae of the male are almost as long as the hind femora. The 
 tegmina are abbreviate, about as long as the pronotum, subelliptical 
 with rounded apex. The hind tibiae are greenish and have ten to 
 twelve spines in the outer series. 
 
 The extremity of the male abdomen is hardly clavate and the supra- 
 anal plate triangular with distinct median sulcus and mesially notched 
 lateral margins; the furcula consists of a small pair of tapering fingers; 
 the cerci are large and broad, almost equally broad throughout, and 
 apically rounded, nearly straight; the subgenital plate is broad and 
 short, the apical margin elevated to a blunt tubercle. 
 
 The single species occurs in Idaho.

 (Plate XIV, fig. 4.) 
 
 Of medium size, brownish fuscous above, sordid testaceous beneath. 
 Head a little prominent, olivaceo-testaceous necked with fuscous, above 
 blackish fuscous with a broad piceous post ocular baud; vertex some- 
 what tumid, scarcely elevated above the pronotum, the interspace 
 between the eyes half as broad again as the first antennal joint; fas- 
 tigium steeply declivent, shallowly and broadly sulcate; frontal costa 
 scarcely reaching the clypeus, faintly expanded at the ocellus, but 
 otherwise equal, a little narrower than the interspace between the eyes, 
 a little sulcate below the ocellus, distinctly punctate above; eyes rather 
 large, not prominent, somewhat longer than the intraocular portion of 
 the genae; antennae castaneous, almost as long as the hind femora. 
 Prouotum slightly expanding on the metazoua, the sides with a per- 
 current, piceous, postocular stripe which is rather feeble on the nieta- 
 zona, the disk rather broadly convex, passing by a rounded shoulder, 
 posteriorly forming feeble lateral carinae, into the somewhat tumid 
 vertical lateral lobes; median carina distinct on the metazona, obsoles- 
 cent on the prozona; front margin subtruncate, hind margin very 
 broadly rotundate ; prozona distinctly longitudinal, about a third longer 
 than the finely punctate metazona. Prosternal spine long, conical, 
 bluntly pointed, feebly appressed; interspace between mesosternal 
 lobes subqnadrate, barely longer than broad. Teginina abbreviate, 
 almost as long as the pronotum, slightly distant, obovate, almost twice 
 as long as broad, the tip strongly rounded. Fore and middle femora 
 somewhat tumid in the male; hind femora rather slender, somewhat 
 compressed, ferrugineo-testaceous, irregularly clouded and necked with 
 fuscous, the under face flavo-olivaceous, the upper genicular lobe and 
 base of lower black; hind tibiae sordid pale greenish with a fuscous 
 patellar anuulus, the spines black almost to their base, ten to twelve 
 in number in the outer series. Extremity of male abdomen hardly 
 clavate, somewhat recurved, the supraanal plate triangular with acut- 
 angulate apex, the lateral margins considerably and rather abruptly 
 elevated and mesially notched, the median sulcus distinct and percur- 
 rent between rather narrow and sharp ridges which fade beyond the 
 middle; furcula consisting of a pair of rather slender, tapering and 
 acuminate, tumid, feebly arcuate and slightly divergent fingers, 
 slightly longer than the last dorsal segment; cerci broad and rather 
 coarse, straight, subequal, apically rounded or subangulate laminae, 
 nearly four times as long as their middle breadth, obliquely vertical 
 throughout except apically, where by a feeble twist they become verti- 
 cal; subgenital plate short and broad, the apical margin rising consid- 
 erably above the lateral into a slight rounded tubercle, the lateral and 
 apical margins as seen from above parabolic.

 One male. Salmon City, Leinhi County, Idaho, August (L. Bruner). 
 
 This species has a close general resemblance to Podisma inarsliallii 
 with its much shorter antennae and wide separation of the mesosternal 
 lobes. 
 
 11. MANCUS SEEIES. 
 
 In this group, composed of species mostly of small size, the prozona 
 of the male varies from quadrate to distinctly longitudinal, and the 
 interspace bet ween the mesosternal lobes of the same sex varies from a 
 little longer than broad to more than twice as long as broad. Tl e 
 antennae of the male are rarely as long as the hind femora. The teg- 
 mina are always abbreviate, about as long as the pronotuui, usually 
 rather broad and either augulate or more or less acuminate at tip. The 
 hind tibiae are red, rarely greenish, and have nine to sixteen, more com- 
 monly about eleven, spines in the outer series. 
 
 The extremity of the male abdomen is usually very feebly clavato, 
 and the supraanal plate usually triangular and rather flat except for the 
 submediaii ridges; but it is sometimes long subclypeate with margins 
 more or less raised; the furcula always consists of a feeble or rather 
 feeble pair of denticulations ; the cerci are generally rather small, some- 
 times nearly equal, at others tapering more or less in the basal half, 
 but rarely anywhere very slender, generally incurved or inbent, and 
 occasionally somewhat arcuate as seen laterally, always well rounded 
 apically and generally exteriorly sulcate on the apical half; the sub- 
 genital plate is broad, generally also short, subconical or subpyramidal, 
 the lateral and apical margins in the same plane and entire. 
 
 The species are five in number and have together a wide range, though 
 all but one are rather local, so far as known. The one which is widely 
 distributed occurs from Nebraska and Kansas to Texas in the West, 
 and from southern New England and central New York to Virginia in 
 the East. The other species are known respectively from Lower Cali- 
 fornia, Colorado, Idaho, and northern New England, but the last is also 
 reported from Illinois. 
 
 This series represents in brachypterous forms the glaucipes series in 
 macropterous, and in an ideal arrangement the series should not be so 
 widely separated as here.

 It has also been reported from New Jersey (Smith), Ithaca, New York 
 (Comstock), Normal, McLean County, Illinois (Thomas), various parts 
 of Kentucky (Garman), Topeka, Shawnee County, Kansas (Bruner), 
 and, with doubt, by Thomas from Colorado " subalpine" and southern 
 Colorado. 
 
 The species varies to a considerable degree, as appears in part from 
 the above description. Texan specimens have the tegmina uniformly 
 less acuminate apically and a longer furcula. Occasionally the tegmina 
 are considerably longer than the pronotum, as appears especially in a 
 pair sent me by Professor H. Garrnan from Kentucky. Specimens 
 from southern New England appear uniformly somewhat smaller than 
 others, while there is no difference in size between specimens from 
 Maryland and Texas. 
 
 Walsli, supposing the species here described as M. walslm to be the 
 true M. scudderi, named the present species in his letters Pezotettix 
 rubricrusj and I still possess several specimens sent me by him in 1865 
 under that name. Examination of the types of Uhler and Thomas 
 show that scudderi and unicolor are identical, as McNeill thought. 
 
 Eiley states that this species attains maturity in the vicinity of Saint 
 Louis, Missouri, about September 1, and begins to oviposit on Septem- 
 ber 24. The eggs have a quadrilinear arrangement in the pod. Uhler 
 found it abundant near Baltimore, Maryland, on " the sides of high 
 hills," Beutenmiiller about New York City in u dry places," and Com- 
 stock about Ithaca, New York, "among scattered trees on the crests 
 and slopes of our highest hills." In the West, however, Allen found it 
 in Iowa u common in grassy groves" and " on prairies," while McNeill 
 says that in Illinois it "is very frequently found along roadsides or in 
 pastures," and in Indiana Blatchley finds it "in open woods and 
 pastures."

 12. DAWSOKI SERIES. 
 
 This group is composed of rather heterogeneous material if the ma- 
 cropterous forms alone are considered, and is even more loosely com- 
 pacted when the brachypterous species are mingled with them. In 
 size they range from rather small to medium. A single species is 
 dimorphic, being both brachypterous and macropterous, 
 
NO. 1124. REVISION OF THE MELANOPLISCUDDEB. 221 
 
 The prozona is quadrate or subquadrate in the male, but in some 
 brachypterous forms longitudinal. The interspace between the meso- 
 sternal lobes in the same sex is always longer than broad and sometimes 
 more than twice as long as broad. The tegmina are either fully devel 
 oped or slightly abbreviate so as not to surpass the hind femora, or 
 else they are shorter than the pronotum, and then apically rounded or 
 very bluntly subacuminate, generally slightly maculate. The hind 
 tibiae vary in color, and have from nine to thirteen spines in the outer 
 series. 
 
 The supraanal plate of the male is generally as in the femur-rubrum 
 series, but the apical third or more is frequently depressed. The fur- 
 cula is very variable, being either as in the devastator series, but gen- 
 erally rather shorter, or reduced to distant slight dentations or to 
 rounded partially projecting lobes. The cerci are generally symmetric- 
 ally rounded at tip and otherwise as in the femur-rubrum series, or 
 with very slight difference in breadth basally and apically, usually 
 rather short, and in one instance bent abruptly inward at less than a 
 right angle. The subgenital plate is usually broad throughout, the 
 apical margin well rounded and slightly elevated but not emarginate? 
 but sometimes it is rather narrow throughout and not apically elevated. 
 
 The species of this group, seven in number, are divided unequally 
 between macropterous and brachypterous forms, one species being di- 
 morphic, four others brachypterous, and two macropterous. They 
 occur almost wholly in the great interior region between the Mississippi 
 River and the Eocky Mountains, and extend from Alberta and Assini- 
 boia to central Mexico. No species are known from the Pacific Coast 
 and only one east of the Mississippi, in Georgia and North Carolina.

 It seems very probable that this species is the Pezotettlx zimmermanni 
 of Saussure, described from the female only, but I find it impossible to 
 determine from the description. If it should so prove, of course the 
 name has priority over the one here employed.

 Allen found the species in Iowa in grass on prairies. 
 
 There are two very distinct forms of this species, differing however 
 only in the length of the organs of flight, the tegmina being abbreviated 
 and subacuminate at tip in the form M. d. tellustris (retaining the 
 second oldest name for the form incapable of flight), and fully developed, 
 broad and ample, greatly surpassing the hind femora and well rounded

 13. KUSTICUS SERIES. 
 
 This is a tolerably homogeneous group in which the prozona of the 
 male varies from quadrate to distinctly longitudinal and in which the 
 mesosternal lobes of the same sex are separated by an interspace 
 which is rarely a little transverse, usually quadrate or subquadrate, 
 and rarely as much as nearly half as long again as broad. The hind 
 border of the pronoturn is usually very obtusangulate, and the tegmina 
 always abbreviate, usually about as long as the pronotum. The 
 hind tibiae are usually red, rarely pale greenish, with usually ten to 
 eleven spines in the outer series, but sometimes nine or twelve, and in 
 one case only seven spines may be found in the female. 
 
 The male abdomen is usually more or less clavate and recurved, the 
 supraaual plate triangular, its median sulcus inclosed by high walls

 which generally terminate beyond the middle; the furcula is usually 
 developed as slight, tapering denticulations only, and in one case these 
 disappear, but sometimes they are longer so as to be nearly or quite a 
 fourth as long as* the supraanal plate; the cerci are simple blades of 
 moderate breadth, generally a little arcuate, tapering a little in the 
 proximal, subequal in the distal half and rounded apically, not reach 
 ing the tip of the supraanal plate; the subgenital plate is small ami 
 the lateral and apical margins usually on the same plane, except for a 
 slight apical elevation or angulation which may take the form of a 
 tubercle, but in one species this also is wanting. 
 
 The species, mostly of medium or small size and seven in number, 
 have a tolerably wide range in the western portion of the continent, 
 from Washington, South Dakota, and Michigan to southern California, 
 Texas, and Mexico; but with a single exception (Montana), the same 
 district does not support two species. One species is found about and 
 near the upper Mississippi, a second along the eastern border of the 
 Eocky Mountains from Montana to New Mexico, a third in Montana, 
 a fourth in Washington, and the others respectively in southern Cali- 
 fornia, Texas, and Mexico.

 This species was determined in 1805 by the late B. I). Walsh as Fez. 
 scudderi Uhler, described from the same place but quite distinct. It is 
 possible that the two sexes here described belong to two different spe- 
 cies, as there is considerable and unusual difference between them in 
 the shape of the eye and the character of the postocular band; but 
 they agree so well otherwise, and show the same pallid annulus on the 
 hind tibiae, that I regard them as the same. If distinct, the name he: e 
 applied should be given to the female, as only the female was received 
 from Walsh. The male comes from Michigan.

 which he regards as equivalent to Paroxya Scudder, and which he defines

 fore, not equivalent to Paroxya as I formerly denned it and as I here 
 still more closely distinguish it from the other genera. 
 
 14. BOECKII SERIES. 
 
 A homogeneous group in which the prozona of the male is distinctly 
 longitudinal and from a third to a half longer than the metazoua, the 
 posterior margin of the pronotum being subtruncate. The interspace 
 between the mesosternal lobes in the same sex varies from a little longer 
 than broad to twice as long as broad. The antennae vary considerably 
 in length, but generally differ but little between the two sexes. There 
 is also little diversity between the sexes in the prominence of the eyes. 
 The hind tibiae are dark blue, sometimes purplish, and have nine to 
 twelve spines in the outer series. 
 
 The supraanal plate is triangular with acutangulate or rectangulate 
 apex; the furcula is reduced to mere projecting points; the cerci are 
 broad and swollen at the base, taper rapidly, and terminate in a slen- 
 der, produced, more or less curling finger; the supraanal plate is either 
 very narrow as compared to its length and then deeply hollowed apic- 
 ally, with a strongly sinuate lateral margin, or it is only a little longer 
 than broad with a nearly straight margin, the apical margin always 
 entire. 
 
 There are six species, ranging from rather small to a little above the 
 medium size, and they are mainly confined to the Pacific coast from 
 Washington to California. But one of the species occurs also as far 
 inland as Idaho and Wyoming, and another is known from San Luis 
 Potosi, Mexico.

 beneath at least on the prozona with a narrow bordering of black, occa- 
 sionally extending, but generally as a feeble suffusion, over the upper

 As there is considerable variation in the slenderness of the tegmina, 
 the name given by McNeill is not closely applicable. 
 
 It is possible that the single female from Monterey County does not 
 belong here, as it varies from the others, as indicated in part by the 
 description, in having a subbasal annulus on the hind tibiae, and has 
 considerably broader tegmina than any of the others and hardly any 
 trace of markings on the hind femora. If it is distinct, it indicates an 
 undescribed species of this same series very closely allied to the present.

 apex and feebly and broadly crenate margins, the sharp and low ridges 
 bounding the exceptionally shallow and flat median sulcus forming a 
 broad triangle in somewhat less than the basal half of the plate, though 
 the sulcus continues as a delicate incision and broadens a little at the 
 apex; furcula consisting only of the rectangulate but projecting inner 
 corners of the gradually broadening divided lateral halves of the last 
 dorsal segment; cerci broad at base, gently tumid, rapidly and regu-

 This species is very close indeed to the preceding, but differs from k 
 in lacking the lateral carinaeof the prouotumand the angulations rep- 
 resenting the furcula, in the possession of an apical tubercle to the 
 supra-anal plate, and in the heavier flavous stripe of the disk of the 
 pronotum.

 very closely descriptive of them.

 in basal, black in apical half, nine to eleven, usually ten, in number 
 in the outer series. Extremity of male abdomen clavate, considerably 
 recurved, the supraanal plate hastate with rectangulate apex, the sur- 
 face nearly plane, the median sulcus shallow, narrow, and narrowing, 
 inclosed between low rounded walls, which unite near the middle of the 
 plate; furcula reduced to two slight, approximate, blunt denticulatious, 
 overlying the base of the just-mentioned ridges; cerci broad at base, 
 tapering rapidly and subequally so as to form long triangular plates, 
 faintly incurved, apically faintly decuived and finely acuminate at 
 tip, the lower margin faintly concave; subgenital plate small, not much 
 longer than broad, very broadly and bluntly subconical, the cone form-

 15. PUER SERIES. 
 
 In the species of this small group, the prozona of the male (and 
 generally of the female) is longitudinal and nearly twice as long as 
 the metazona, with its truncate or feebly produced hind margin; the 
 median carina is similar throughout. The interspace between the 
 mesosternal lobes in the same sex is slightly or much longer than 
 broad. The male antennae are long and considerably longer propor- 
 tionately than those of the female. The tegmina are abbreviate, of 
 about the length of the pronotum, obovate and apically rounded. 
 The hind tibiae are prevailingly glaucous, the spines ten to eleven, 
 rarely nine, in number in the outer series. 
 
 The supraanal plate of the male is triangular or hastate, the surface 
 subtectate with a deep median sulcus; the furcula is variable in length, 
 either reduced to mere denticulations or developed as parallel spines 
 nearly a third as long as the supraanal plate; the cerci are small and 
 styliforin with slight concavity of the upper margin, acuminate and 
 much shorter than the supraanal plate; the subgenital plate varies 
 considerably but is rather full, and the apical margin entire. 
 
 Two species are known, one very small from Florida, the other rather 
 large from Texas, and they are brought together in one group princi- 
 pally fioni their simple styliforin cerci.

 half as long again as broad, the apex not at all produced, slightly over- 
 lapping at their inner margins. Extremity of male abdomen a little 
 clavate, somewhat recurved, the supraanal plate triangular, of about

 10. INOKNATUS SEBIES. 
 
 The prozoua of the male is here distinctly longitudinal, and the 
 interspace between the mesosternal lobes in the same sex quadrate, 
 or feebly longitudinal. The hind margin of the pronotum is either 
 truncate or very broadly obtusangulate. The tegmina are abbreviate 
 and nearly as long as if not somewhat longer than the pronotuin, some- 
 times rounded and sometimes subacuininate apically. The hind tibiae 
 are generally green, and the species vary much in the number of spines 
 in the outer series, ranging from nine to fifteen. 
 
 The supraanal plate is triangular and generally rather flat, the lateral 
 margins hardly elevated; the furcula may be either reduced to slight 
 prominences or produced as delicate spines crossing the basal fourth of 
 the supraanal plate; the cerci again vary considerably, being either 
 stout, strongly constricted in the middle and widely expanded apically, 
 or tapering to a half or two-thirds the basal breadth and then forming 
 a relatively slender, slightly decurved, compressed finger; the subgeni- 
 tal plate is narrower, generally considerably narrower, than long, with 
 angulate, slightly elevated and tuberculate extremity. 
 
 The species are rather slender, of about medium size, and are three 
 in number. One occurs in Mexico, a second in North Carolina, and the 
 third in Illinois and Indiana.

 Vigo County, Indiana, May 25, June 8, 11, Blatchley (W. S. Blatchley; 
 A. P. Morse). A specimen in the U. S. National Museum from Montana 
 perhaps belongs here. 
 
 It has also been reported by McNeill from McLean County, Illinois, 
 and Monroe County, Indiana. 
 
 This species is remarkable for the length of the antennae. It matures 
 very early, McNeill having taken it as early as June 5 in Illinois, where 
 he thinks it is the first Orthopteron to mature from eggs of the same 
 season. Blatchley records it in Indiana even as early as May 11. 
 McNeill says "it is by no means common, . . . being restricted to 
 a few localities [about Moline]. It shows a decided preference for the 
 sides of open, grassy ravines." One specimen before me is marked by 
 Blatchley as found in woods. 
 
 The species has never before been described, but has been mentioned 
 by Walsh's names in several publications; the specific name "viridu- 
 lus" used on one or two occasions was a misreading of Walsh's name 
 "viridicrus," and probably originally due to bad chirography on my 
 part.

 consisting of a pair of basally attingeut, divergent, slender, tapering, 
 acuminate fingers, crossing rather more than a fourth of the supraanal 
 plate; cerci composed of a moderately broad, rapidly tapering, slightly 
 tumid, basal portion, about one-third of the whole, and a very slender,

 In general appearance this insect has a strong resemblance to Jf. 
 attenuatus from the same region. 
 
 17. FASCIATUS SERIES. 
 
 This group is not very homogeneous, comprising forms of comsider- 
 able difference in appearance and structure, but which have a number 
 of important points in common. It is composed in part of brachypter- 
 ous and in part of macropterous forms. One species is dimorphic in 
 this respect, and the others, whether macropterous (one only) or 
 brachypterous (six in number), are exceptionally short-winged or 
 exceptionally long- winged for their type. The antennae are very vari- 
 able in length, being sometimes quite similar, sometimes quite dissimi- 
 lar, in the two sexes and varying in the male from three-fifths as long 
 as the hind femora to equal their length, and in the female from one- 
 half to four-fifths the length of the hind femora. In size they range 
 from very small to a little above the medium. 
 
 The prozona of the male varies from quadrate to longitudinal in 
 both brachypterous and macropterous forms. The interspace between 
 the mesosternal lobes in the same sex is also very variable in each set 
 of forms, and in both together ranges from a little transverse to twice 
 as long as broad. The tegmina in the brachypterous forms are usually 
 comparable with the length of the pronotuni and are well rounded, but 
 in the dimorphic form they are apically subacuminate and twice as long- 
 as the pronotum (as in one of the brachypterous forms) or far surpass 
 the hind femora and are broad and well rounded apically; while in the 
 single macropterous form they barely reach the tip of the hind femora. 
 The hind tibiae are likewise very variable in color, sometimes within the 
 species, and have from nine to twelve, usually eleven, spines in the 
 outer series. 
 
 The supraanal plate is generally rather long triangular, and rather 
 flat, with but feebly elevated margins, except in one instance, where it 
 is strongly compressed apically. The furcula is usually very feebly 
 developed, but three species have slender fingers extending some dis- 
 tance over the supraanal plate. The cerci are rather large, compressed, 
 generally incurved laminae, generally of considerable breadth, but in 
 one instance exceptionally slender, generally more or less constricted 
 mesially, in two species greatly, and, with a single exception, enlarged 
 again apieally, rounded and not acuminate (in one species emarginate) 
 at tip. The subgenital plate again varies much, but is always longer 
 than broad, generally moderately broad and nearly equal and usually 
 a little elevated apically, the apical margin always entire. 
 
 The eight species have as little geographical as structural relation. 
 One is known only from the extreme north in Labrador and Greenland 5

 two from Florida only; another only from Oregon and Washington; a 
 fifth from Kentucky; a sixth from North Carolina; a seventh from 
 Indiana, Texas, and, perhaps, Carolina; while the eighth occurs across 
 the continent from Newfoundland and New Jersey in the east to Wash- 
 ington in the west, and from the Saskatchewan to Colorado.

 It is stated by Bruner that this species is u to be met with in the 
 mountains of Montana, Idaho, and Wyoming," and it " appears to 
 abound only where two or three particular plants are met with, one of 
 which is a species of geranium. 7 ' 
 
 The female of this species closely resembles the same sex of M. boreMi, 
 but has relatively longer antennae, about as long as those of the male ? 
 and the tegmiua are shorter and more strongly rounded at tip.

 Blatchley also reports it from Monroe County, Indiana, and if Saus- 
 sure's species is the same it is also found in Carolina. Blatchley says 
 "it reaches maturity about September 1, and frequents for the most 
 part high, dry, open woods, especially those in which beech and oak 
 trees predominate ... In late October, if the season is dry, it is 
 often found . . . among the reeds and tall rank grasses near the 
 border of marshes."

 from Alaska perhaps belongs here. 
 
 The species has also been reported from Montana (Thomas), north- 
 west Nebraska (Bruner), Souris River, Assiniboia (Scudder), Lake of 
 the Woods, Manitoba (Caulfield), Minnesota (Scudder), mountains east 
 of Middle Park, Colorado (Thomas), and New Jersey (Beutenmiiller). 
 It therefore occurs in a broad belt along our northern border from the 
 Atlantic nearly or quite to the Pacific. 
 
 As seen in the above description, the species occurs in two forms, a 
 moderately short-winged form, to which the name Jl/./. curtits (Plate 
 XV III, figs. 2-3) maybe given (it was once described as citrtits); and 
 a very long and broad winged form, which may be called JL/. volaticus 
 (Plates I, fig. c; XVIII, fig. 4). The latter is known only from Michi- 
 gan, and was brought to my attention by Professor Bruner. 
 
 Duriug a recent visit to London, Mr. Samuel Henshaw, to whom I 
 had given specimens of this species for the purpose, verified by com- 
 parison with the types in the British Museum their identity with 
 Walker's Caloptenus fasciatus.

 Fieber also reports it from Greenland and North Cape, Norway. It is, 
 however, not included in the European fauna either by H. Fischer or by 
 B runner von Wattenwyl; yet Fieber credits specimens to the Vienna 
 Museum, in which city Brunner lives. Hofrath Bruuner writes me that 
 he possesses specimens from Labrador, Hudson Bay, and Valdivia, 
 Chile. I can not forbear expressing a doubt about the accuracy of this 
 last locality. 
 
 As Melanoplus and Podisma are the genera of Melanopli most abun- 
 dant in forms and most widely spread, the former being especially true 
 of Melanoplus, and as the present form is the species of Melanoplus 
 most nearly allied to Podisma, and, like most of the species of the 
 latter genus, is peculiar to high latitudes or altitudes, it seems proper 
 to regard M. borealis as an archaic form, perhaps more nearly than any 
 other resembling the original form from which the Melanopli as a whole 
 have descended. 
 
 Mr. Samuel Henshaw recently compared for me a female specimen of 
 this species from Labrador with Walker's type of Caloptenus arcticus 
 in the British Museum. He found them to agree except in length of 
 wings, which in Walker's specimen, a unique, "extend slightly beyond 
 the abdomen ;" the prosterual spine was the same. I have accordingly 
 introduced it in the synonymy with a question mark; if it belongs here 
 the range of the species should be extended to whatever point it may 
 have been in "Arctic America" that Doctor Kae collected his specimen. 
 
 The specimens which I have seen were taken by Mr. Sornberger 
 August 15-1G at the Esquimaux village of Kama. He tells me that 
 they were all taken on the banks of a mountain brook fed by the melt- 
 ing snows of the summit near by. They were most abundant where 
 the vegetation was most luxuriant at the boulers of the brook; none 
 were found below an elevation of 200 feet nor above 1,500 feet, at which 
 altitude herbaceous plants became few and scattering. Mr. Sornber- 
 ger can not say upon what it fed, but it was not found on any of 
 the shrubby plants common there Betula, Vaccinium, Ledum, Salix, 
 Eiupetriim, etc., though he thinks he saw it on some of the Cyperaceae.

 In this small series the prozona of the male is slightly longitudinal, 
 and the interspace between the mesosternal lobes in the same sex only 
 a little longer than broad. The antennae are very long. The tegmina 
 are always abbreviate, but vary considerably, being either elliptical, 
 attingent, and about as long as the pronotum, or lanceolate, overlap 
 ping and reaching a little beyond the middle of the hind femora. The

 latter are rather short, and the hind tibiae either red or glaucous, with 
 nine to eleven spines in the outer series. 
 
 The supraanal plate is triangular, with raised margins; the furcula 
 consists of a pair of slight and distant or very distant projections; the 
 cerci are stout and heavy, two or three times as long as broad, mesially 
 contracted and apically augulate; the subgenital plate is broad, 
 broader than long by the greater or less elevation of the entire and 
 well-rounded apical margin. 
 
 There are but two species known, of medium size, one from New 
 Mexico and the other from Iowa and Dakota.

 This species is very closely related to Mel. fasciatiiSj but has an api- 
 cally broader, less thickened, and regularly arcuate subgenital plate, 
 and slightly different cerci, these being considerably broader at base 
 than apically. It is named for my ornithological friend, Mr. J. A. Allen, 
 of the American Museum of Natural History, who many years ago 
 obtained for me much of the material on which this memoir is based.

 This is a dominant and homogeneous group of medium or rather small- 
 sized species, in which the male prozona varies from slightly transverse 
 to slightly longitudinal, and the interspace between the niesosternal 
 lobes in the same sex is as in the spretus series. The tegmiua are 
 always fully developed or a little abbreviated (so as to fall a little 
 short of the tip of the hind femora), immaculate or slightly maculate 
 along the middle line. The hind tibiae are normally red and have ten 
 to fourteen spines in the outer series. 
 
 The supraanal plate is clypeate, longer than broad and mesially con- 
 stricted. The furcula consists of a pair of parallel or nearly parallel, 
 long or moderately long, generally separated, slender, tapering, sub- 
 cylindrical fingers or spines. The cerci are compressed subfalcate

 laminae, the apical half generally about half as broad as the base, 
 arcuate and with the upper inner portion of the tip produced. The 
 subgenital plate is peculiar for being very broad at base and narrowing 
 so as to be at apex only about half as broad as at base (which does not 
 show in the figures), the whole lower margin nearly straight while the 
 upper is sinuous, the apical margin not elevated, entire (in one species 
 very broadly and shallowly emarginate, or rather laterally tuberculate) 
 and, as viewed above, broadly rounded. 
 
 The species, five in number, are spread all over the continent from 
 Atlantic to Pacific, from central Labrador to central Florida, and from 
 central Alaska, the Mackenzie Kiver and Hudson Bay to Texas and 
 central Mexico; they also extend to high altitudes above the forest line. 
 No other series of Melanoplus has quite so wide an area of distribution, 
 the bivittatus- series, however, approaching it closely.

 Of medium size, very dark fusco- olivaceous, with bright luteous or 
 flavous markings. Head feebly prominent, mostly luteous or flavous, 
 more or less infusca>ted above and especially clouded or flecked with 
 fuscous along the lateral margins of the fastigium and posterior to 
 them, and with a blackish postocular band; vertex somewhat tumid, 
 the interspace between the eyes nearly (male) or more than (female) 
 half as broad again as the first anteunal joint; fastigium steeply decliv- 
 ent, feebly expanding anteriorly, shallowly sulcate throughout; frontal 
 costa somewhat prominent above, slightly contracted between the 
 antennae, otherwise subequal and as wide as the interspace between 
 the eyes, hardly reaching the clypeus, feebly sulcate at and below the 
 ocellus, biseriately punctate throughout; eyes moderately large, not 
 very prominent, distinctly longer, especially in the female, than the 
 infraocular portion of the geuae; antennae more or less ferruginous, 
 apically infuscated, less than three- fourths (male) or hardly more than 
 one-half (female) as long as the hind femora. Pronotum subequal, very 
 feebly and uniformly expanding posteriorly, especially in the female, 
 the disk dark fusco-olivaceous, with a slender, median, flavous stripe 
 and more or less distinct lateral stripes of the same upon the carinae, 
 expanding upon the metazona, the lateral lobes mostly flavous (some- 
 times obscured with fuscous), the prozona marked above with a broad 
 piceous band; disk nearly plane, passing by abruptly rounded shoul- 
 ders, hardly forming true carinae, into the vertical lateral lobes ; median 
 carina distinct but slight throughout, hardly less elevated on the pro- 
 zona; front margin truncate, hind margin obtusangulate; prozoua

 quadrate or feebly longitudinal (male) or a little transverse (female), 
 scarcely or not longer than the closely punctate metazona. Prosternal 
 spine moderately long, erect, cylindrical, in the female slightly appressed, 
 blunt; interspace between mesosternal lobes fully half as long again 
 as broad (male) or feebly transverse (female). Tegmina generally sur- 
 passing a little the hind femora, of moderate breadth, distinctly tapering, 
 olivaceo-fuscous, immaculate or with a feeble line of minute maculations 
 along the discoidal area; wings hyaline, glistening and iridescent, with 
 pale fuscous veins darker next the apex. Fore and middle femora 
 scarcely tumid in the male; hind femora blackish olivaceous on the 
 outer face excepting sometimes on the lower margin, elsewhere flavous 
 or luteo-flavous,with two broad blackish olivaceous maculatious above, 
 especially on the inner side; hind tibiae feebly valgate, red, the spines 
 black excepting at base, eleven to thirteen in number in the outer 
 series. Extremity of male abdomen considerably clavate, somewhat 
 recurved, the supraanal plate subclypeate but mesially contracted, 
 apically rectaugulate, the margins considerably elevated, forming 
 deep valleys between them and the opposite curved ridges border- 
 ing the median sulcus; the latter is deep, gradually contracts toward 
 the middle and then rapidly expands and shallows (in the specimen 
 chosen for illustration the apical portion is concealed); furcula consist- 
 ing of a pair of basally adjacent, apically tapering, parallel, acuminate 
 fingers, nearly half as long as the supraanal plate, lying in the valleys 
 of the same; cerci subfalciform lamellae, which taper rapidly in the 
 basal half and beyond are less than half as broad, slightly incurved 
 and upcurved, apically tapering by the curve of the lower margin, the 
 tip blunt and falling short of the extremity of the supraanal plate; 
 subgenital plate broad at base, narrowing rapidly, the extremity hardly 
 more than half as broad as the base, the lateral margins strongly arcu- 
 ate, the apical margin even, entire, well rounded. 
 
 Length of body, male 20 mm., female 25 mm. ; antennae, male 8.5 mm., 
 female 6.75 mm.; tegmina, male 17 mm., female 17.5 mm.; hind femora, 
 male 12 mm., female 13.25 mm.

 and it has since been recorded by Bruner from Canyon City, Fremont 
 County, Colorado, and the plains of Wyoming. 
 
 This species, especially in life, is strikingly different from the next 
 two in coloring, though the male abdominal appendages are exceedingly 
 similar. According to Bruner. it is more clumsy in its movements than

 f\ Of medium size, brownish fuscous, often with a more or less feeble 
 ferruginous tinge, particularly in the female. Head a little prominent, 
 olivaceo plumbeous, above much infuscated, especially in a pair of wid- 
 ening stripes behind the lateral margins of the fastigium, and with a 
 piceous postocular stripe ; interspace between the eyes distinctly wider 
 than (male) or fully twice as wide as (female) the first anteunal joint; 
 fastigium strongly declivent, considerably (male) or shallowly (female) 
 sulcate, but variable; frontal costa just failing to reach the clypeus, 
 subequal, as broad as the interspace between the eyes, sulcate at and

 in the male, than the infraocular portion of the genae; antennae fer- 
 ruginous or luteo-ferruginous, often a little infuscated apically, about 
 four-fifths (male) or three-fifths (female) as long as the hind femora. 
 Pronotum feebly and rather regularly expanding posteriorly, the disk 
 faintly convex and passing by a well-rounded shoulder (somewhat 
 abruptly on the metazona) into the anteriorly tumid vertical lateral 
 lobes, the disk generally darker than the lower portion of the lat-

 extent or conspicuousuess beyond the middle; wings moderately broad, 
 hyaline, glistening, with fuscous veins and cross veins darkest apically 
 and anteriorly. Thoracic pleura piceous or blackish fuscous, the meta- 
 thoracic episterna with a mesial streak of flavous of greater or less 
 clarity. Fore and middle femora distinctly but not greatly tumid in 
 the male; hind femorai olivaceo- testaceous, more or less heavily and 
 very variably obscured or clouded with fuscous, the fuscous coloring 
 generally confined to the upper half, and above generally concentrated 
 in two fasciae, which sometimes extend partly in an oblique direction 
 on the outer face, but generally in a very obscure fashion, if at all, 
 while the whole under surface and at least the basal half of the inner 
 surface is more or less impure flavous, sometimes deepening, especially 
 beneath, to ferruginous or even carmine; hind tibiae normally red, 
 sometimes with a slight fuscous patellar spot, occasionally more or 
 less tinged with yellowish, very rarely pale green with a yellowish 
 tinge, the spines black nearly to their base, ten to thirteen, usually 
 eleven, in number in th.e outer series. Extremity of male abdomen 
 rather strongly clavate, well recurved, the supraanal plate clypeate, 
 strongly and rather abruptly contracted mesially. the apex subreet- 
 angulate, the lateral margins elevated, the apical portion more or less 
 cleflexed, the median sulcus rather large, not very deep, bounded by 
 moderate but rather abrupt walls, apically expanding and obsoles- 
 cent; furcula consisting of a pair of subparallel or sometimes feebly 
 divergent, tapering, subacuminate, apjcally well separated, more or 
 less feebly depressed fingers, falling a little short of the middle of the 
 supraanal plate, and except at extreme base lying on the outer side of 
 the ridges bounding its median sulcus; cerci rudely subfalciform, com- 
 pressed laminae, tapering considerably and rather rapidly from base to 
 middle, beyond that subequal but apically very obliquely truncate, so 
 that the upper angle is considerably produced but blunt, the whole 
 somewhat incurved and failing to reach the tip of the supraaual plate; 
 infracercal plates exceedingly broad at base, extending laterally far 
 beyond the sides of the cerci, as long as the supraanal plate; subgeni- 
 tal plate very short apically so as to be less than half the breadth of 
 the base, the lower margin straight, the lateral margin very sinuous, 
 the apical margin not elevated, strongly rounded, entire.

 New Jersey (Smith); Pennsylvania (De Geer); Ohio and West Vir- 
 ginia (Glover) ; Kentucky (Glover, Garmau) ; Tennessee (De Haan), and 
 Wyoming (Thomas). Specimens from Florida which I formerly referred 
 to this species probably belong to the next. 
 
 It therefore appears to inhabit the entire United States and the set- 
 tled parts of Canada, excepting only Alaska and also the southeastern 
 United States (where it is replaced by the next species), and occurs 
 south of our border as far as central Mexico. 
 
 The species described by me as J/\ interior was based upon specimens 
 from Utah and other parts of the interior of the western country, which 
 seem to differ from those found elsewhere in having cerci which taper 
 more gradually and show less contrast in the width of the basal and 
 apical halves, and at tip are blunter and less manifestly truncate r in 
 which also the forks of the furcula are relatively longer and more 
 strictly parallel, the tegmiua rather shorter and generally lacking any 
 maculatioii whatever; the prostemal spine also is more frequently coin- 
 pressed before the tumid tip ; but on comparing a large series of speci- 
 mens from these western regions I find it impossible to draw any line 
 of demarcation, some specimens having some but not other of these 
 characteristics, so that I can only regard the species as in a state of 
 flux in this region, preparing, as it were, to divide into distinct races 
 not yet clearly enough defined to distinguish them. 
 
 1 The first three references are doubtful ; they probably belong to M, extremes.

 "]/. devorator was founded upon specimens of strikingly contrasted 
 coloration found in Texas, which I have since seen from many other 
 places; but as they are united with the type by complete series of 
 intergrades, I am forced to conclude them to be only extreme color- 
 ational variations, which can not be dignified even as races. 
 
 Specimens with green or greenish hind tibiae have been seen by me 
 from the alpine region of the White Mountains, New Hampshire, Cape 
 Cod, Nantucket, Great Island, and Cambridge, Massachusetts, Utah, 
 Carrizo Springs, Texas, and Querataro, Mexico. 
 
 There can be no doubt that this is the true femur-riibrum of De Geer, 
 since Stal has described the anal cerci of the male from the type of 
 De Geer's description, and I myself made direct comparisons with 
 varied material when in Sweden, nearly thirty years ago. 
 
 In Hayden's report on the survey of Nebraska (1872), I collected 
 several accounts, printed and unpublished, of the injury to crops attrib- 
 uted to this species in the eastern United States. As up to that time 
 M. atlanis had not been distinguished from M. femur rubrum, it is pos- 
 sible, and I am now inclined to think it probable, that all the serious 
 injury done to crops in the East is done by M. atlanis; for although 
 almost everywhere less common than M. femur -rubrum, M. atlanis has 
 been shown to have the capacity for immense multiplication, and has 
 been directly proved to be the culprit in some instances; as it is also 
 much more closely and indeed very closely related to the destructive 
 locust of the West, M. spretus, it is far more likely to have been the 
 actual pest in all the records of the past. At least until direct provable 
 charges are made against it, M. femur-rubrum should be looked upon 
 as less injurious than M. atlanis ; it is especially doubtful whether it 
 ever migrates in aerial swarms; as a general rule the tegmina and 
 wings are longer in M. atlanis than in M. femur-rubrum, though both 
 species vary considerably and intergrade in that particular. From 
 measurements made on Missouri specimens, Eiley found that the teg- 
 mina in the present species extended beyond the abdomen as follows: 
 In 28 males, 0-2 mm., average, 0.8 mm.; in 54 females, 0-3 mm., aver- 
 age, 1.1 mm. 
 
 Bruner excellently expresses the fact when he says that the imme- 
 diate distribution of this insect " appears to be controlled altogether by 
 climatic conditions, the chief of which is the presence of a certain 
 amount of humidity. . . . It is a frequenter of low grounds, culti- 
 vated fields, shady margins of woods, etc., where vegetation is rank 
 and tender." It is rarely found upon dry hillsides when meadows close 
 at hand may swarm with them, while the opposite is true of other 
 species, M. collinus for instance; yet such specimens as do so occur will 
 be found to differ from those inhabiting more favored localities, in being 
 lighter colored and more uniformly grayish in tone, with slighter con- 
 trasts; those from drier stations appear also to have on the average 
 rather shorter wings.

 There is but a single annual brood which begins to appear full fledged 
 in ]STew England late in July. According to Kiley, the eggs are not 
 laid in a single mass, but at intervals in several; he has twice obtained 
 four successive pods from a single female, covering a period of nearly 
 two months and containing eggs amounting in all to from ninety-six to 
 one hundred and ten. The eggs have a quadrilinear arrangement in 
 the pods. 
 
 At Andover, Massachusetts, on October 5 many years ago I observed 
 a pair of this species, male and female, near together alternately sig- 
 naling to each other with a slight quick movement of the hind legs 
 upon the tegmina, as if stridulating. I made no note of whether any 
 sound was actually produced and do not now recall any. 
 
 Many interesting notes regarding this species will be found in the 
 first report of the United States Entomological Commission.

 This species takes in our Southern Atlantic States the place of M. 
 femur-rubrum, which it closely resembles; it is most quickly distin- 
 guished from it by the form and sculpture of the supraanal plate and 
 the much greater length of the furcula.

 It has also been reported from Quebec (Provancher, Scudder), Dodge 
 County, Nebraska (Dodge), and the Mackenzie Eiver, British America, 
 at latitude 65 (Kirby); the last, however, is uncertain, dependingon the 
 determination of Kirby's species. It probably occurs throughout the 
 larger part of Canada and the northernmost United States. 
 
 As indicated in the description, this insect appears in two forms: a 
 short winged (M. e.junius), in which the tegmina at rest do not reach 
 the tips of the hind femora; and a Jong- winged (for which I propose 
 the name M. e. scandens), in which they surpass them, generally con- 
 siderably. The latter has also a slightly slenderer body, though the 
 difference is not marked. It appears to affect high latitudes and alti- 
 tudes, being found in all the localities in the high north where Kennicott 
 collected, on the Big Horn Mountains in Wyoming, and on the summits 
 of Greylock in Massachusetts, and the White Mountains in New Hamp- 
 shire, in all of which (unless in Wyoming, whence I have only seen two 
 specimens) it is the prevailing or exclusive form. The short-winged 
 form, however, occurs in all these places excepting the Alpine region of 
 the White Mountains, where it has not been taken ; and the long winged 
 occurs also at lower levels in New England, as at North Conway, New 
 Hampshire, Jay and Montgomery, Vermont, and Winchendon, Massa- 
 chusetts, but it is only found in these places exceptionally, to judge 
 from the specimens seen. The two specimens from the Big Horn 
 Mountains, the male scandens, the female junius, are of exceptional 
 size, and Arctic American specimens are also distinctly larger than 
 those from New England or Nebraska.

 It will probably be impossible ever to determine definitely Kirby's 
 Locusta leucostoma, as the description is altogether inadequate and the 
 British Museum does not contain the type; at least I could not find it 
 by special search for it in 1865, and it is not mentioned in Walker's 
 catalogues ; Walker, following my earlier but probably wrong determi- 
 nation, placed it as a synonym of M. bivUtatus, but none of his speci- 
 mens included Kirby's. 
 
 Mr. Samuel Henshaw, during a recent visit to the British Museum, 
 examined the types of Walker's Caloptenus extremus and found them to 
 agree with specimens of the present species coming from Keunicott's 
 collection on the upper Mackenzie, which he took with him; they 
 differed "only in having slightly shorter wings," in which respect 
 Walker's specimens agree with others of Kennicott's collection belonging 
 to this species.

 In this more than usually homogeneous group, the male prozona is 
 quadrate or slightly longitudinal, and the interspace between -the 
 mesosternal lobes of the same sex varies from a little longer than broad 
 to twice as long as broad. The tegmina are always fully developed, 
 surpassing somewhat the hind femora, and at most are feebly maculate, 
 the flecking not always confined closely to the discoidal area. The 
 hind tibiae are blue or green (in one instance apparently reddish yellow) 
 and have ten to twelve spines in the outer series.

 The supraanal plate is generally rather simple, triangular with 
 convex sides and a generally produced apex, but is sometimes strongly 
 and abruptly compressed apically. The furcula is developed to an 
 extreme as a pair of parallel, flattened, pointed plates, usually more 
 than half as long as the supraanal plate. The cerci are rather slender 
 or only moderately broad, apically spatulate or subspatulate, incurved 
 or inbent, of variable length relative to the supraanal plate. The sub- 
 genital plate is moderately broad apically, but distinctly narrower 
 than long, the apical margin entire and not elevated, or only slightly 
 elevated. 
 
 The species, six in number, are of medium or slightly above the 
 medium size and with the exception of the typical species are found 
 only in the extreme Southwestern States Southern California, Arizona, 
 and Texas, and in Lower California and Sonora, but the typical species 
 extends the range on the north to Washington, Idaho, and Wyoming, 
 and eastward to Louisiana and western Nebraska. It is a western 
 type.

 immediate margins elevated slightly and a little overhanging by expan- 
 sion, the median sulcus moderately deep and not broad, uniform ; and

 slenderer cerci, the general characters of the subgenital plate and in 
 minor peculiarities of its structure. It can be confounded with iio> 
 other species.

 This species is certainly very closely allied in structure to the next, 
 M. cinereus, and may prove to be a variety of it, found in different sta- 
 tions. It wholly lacks, however, the cinereous speckling so characteris- 
 tic of typical examples of the latter species, with the rusty hue of the 
 pronotum. 
 
 Some individuals are much smaller than, hardly more than half as 
 large as, others; the measurements are taken from the larger and appar- 
 ently commoner forms.

 It has also been reported from the Yellowstone region and Sioux 
 County, Nebraska (Bruner), Reno, Washoe County, Nevada (Scudder), 
 and tbe San Joaquin Valley, California (Coquillett). 
 
 I have found this insect only upon the sage brush (Artemisia), and so 
 completely do its gray and rusty colors harmonize with its surround- 
 ings that it is extremely difficult to detect when at rest. This has 
 also been noticed by Bruiier, who remarks that the resemblance extends 
 to the earlier stages of the insect. 
 
 Coquillett remarks upon the ease of its flight, describing it as in a 
 straight line, for a distance of from 5 to 20 feet from the ground. He 
 found it devouring the ripe kernels of rye in California, and Eiley 
 reports it as injuring cotton in Louisiana. Coquillett regards it as a 
 migrating species, but his specific statements refer only to short flights 
 from the fields to the tree tops or the reverse, fifty to one hundred 
 yards being the usual distance. In the San Joaquin Valley he found 
 specimens pairing at the last of July.

 This species is rather closely allied to the last, M. complanatipes, but 
 is easily distinguished from it by its less strongly compressed hind 
 femora with their bifasciate markings. The differences in the abdom- 
 inal appendages are slight, but are found at every point. 
 
 21. ANGUSTIPENNIS SERIES. 
 
 A very homogeneous group (and one very closely allied to the pre- 
 ceding), in which the prozona of the male is variable, and the interval 
 between the mesosternal lobes in the same sex varies from a little 
 longer to several times longer than broad. The tegmina are always 
 fully developed and reach or somewhat surpass the tips of the hind 
 femora. The hind tibiae are red or glaucous and have from nine to 
 thirteen spines in the outer series. 
 
 The supraaual plate is long and rounded triangular, and preapically 
 contracted somewhat conspicuously. The furcula consists of a pair of 
 slender, tapering, acuminate fingers of considerable length, generally 
 extending over a third of the supraanal plate. The cerci are rather 
 short and rather slender, incurved or inbent apically, spatulate, not 
 nearly reaching the tip of the supraanal plate. The subgenital plate is 
 large, fully as broad as long, not or but little elevated apically and 
 there usually feebly notched. 
 
 The species, only four in number, are of medium or rather small, 
 occasionally rather large size, and occur from Iowa to Utah, and from 
 Montana and Manitoba to Texas, though one species ranges as far east 
 as Sudbury, Ontario the only one found east of the Mississippi. They 
 occur mostly in the region between the Rocky Mountains and the Mis- 
 sissippi.

 Bruner states that this species feeds on Artemisia and prefers u to 
 jump from plant to plant rather than to alight upon the ground." " It 
 occurs both on high and low lauds, but appears to be somewhat partial 
 to old breakings and well-fed pastures of many years' use.' 7 
 
 I suspect that the insect from Minnesota, described by Thomas 1 as a 
 variety of Caloptenus occidentalis, may belong to this species.

 Thoracic pleura luteous, the incisures black and the mesothoracic epi- 
 inera darber than the ground, often blackish or even black. Tegmina 
 surpassing considerably the hind femora, of normal breadth, feebly 
 tapering, brownish fuscous, with usually very distinct and prominent 
 maculation of quadrate blackish spots, interrupting a median luteous 
 or pallid stripe in the basal half, becoming a sprinkling of blackish 
 dots beyond, sometimes found also more or less obscurely in the other 
 areas; wings moderately broad, hyaline, sometimes very feebly infu- 
 inated at the edge near the tip, the veins bluish fuscous apically and 
 anteriorly. Fore and middle legs only a little tumid in the male, 
 luteo-testaceous flecked with fuscous; hind femora luteo-testaceous, 
 twice barred above with blackish fuscous besides a basal spot, and 
 more or less deeply infuscated geniculation, the bars liable on the 
 middle of the outer face to fuse more or less completely into a 
 median stripe, which sometimes suffuses the whole face; lower face 
 sometimes feebly roseate; hind tibiae very feebly valgate, glaucous, 
 occasionally feebly infuscated, the base and tip feebly lutescent, with 
 a narrow postbasal fusco-glaucous annulus, the spines rather short, black 
 beyond their pallid bases, ten to eleven in number in the outer series. 
 Extremity of male abdomen slightly clavate, upturned but scarcely 
 recurved, the supraanal plate ovate- triangular, broadest at some dis- 
 tance beyond the base, the sides broadly and gently uplifted, the eleva- 
 tion abruptly broken by a preapical lateral transverse sulcation, the 
 apex acutangulate, the median sulcus occupying only the basal half. 
 and very shallow and equal, except when, as sometimes, the apical por- 
 tion is much compressed; furcula consisting of a pair of long and slen- 
 der, equally tapering and acuminate, more or less flattened, slightly 
 divergent and very feebly arcuate fingers, somewhat less than half as 
 long as the supraanal plate; cerci small, compressed, subequal, incurved, 
 lateral plates, gradually and rather slightly contracted mesially, the tip

 well rounded, subspatulate, and exteriorly broadly sulcate or depressed, 
 reaching only the break in the lateral margin of the supraanal plate; 
 infracercal plates extending laterally distinctly beyond the cerci, and 
 apically to the tip of the supraanal plate; subgenital plate pretty regu- 
 larly scoop- shaped, scarcely flaring, the apical margin almost entire, or 
 emarginate only by a feeble lateral elevation of the margin as seen from 
 behind.

 I had formerly mistaken this species for Cal. occidentalis Thomas, and 
 distributed specimens under that name. This note may serve to correct 
 the error. The longer furcula serves somewhat readily to distinguish 
 this species from the preceding, smaller and less heavily maculate 
 species. 
 
 22. PACKARDII SERIES. 
 
 This is a group in which the prozona of the male is usually quadrate 
 or subquadrate, and the interval between the mesothoracic lobes of the 
 same sex varies from quadrate to fully twice as long as broad. The 
 prosternal spine is usually rather short, often appressed. The tegmina 
 are always fully developed and reach or surpass a little the tips of the 
 hind femora; the hind tibiae are generally red, sometimes blue, and 
 have nine to twelve spines in the outer series. 
 
 The supraanal plate is as in the colliuus series. The furcula is 
 slightly developed, consisting of moderately slender deuticu-latious, not 
 longer than the last dorsal segment. The cerci are generally moder- 
 ately broad, gently spatulate, the apical portion generally inbent, 
 sometimes merely incurved, often externally snlcate. The subgenital 
 plate is never very broad, ordinarily rather narrow, subequal or apically 
 narrowed, the apical margin neither elevated nor prolonged, and gen- 
 erally well rounded and entire. 
 
 The five species are of rather large or medium size, and comprise 
 two tolerably distinct sets: one, of two species, of ordinary form, with 
 short, apically truncate cerci, not nearly attaining the tip of the supra- 
 anal plate, and with strongly divergent forks to the furcula; and a 
 second, of three species, of very robust form, cerci which though short

 reach or nearly reach the tip of the supraanal plate and are apically 
 sulcate, with parallel or subparallel distant forks to the furcula. 
 
 The species are all found west of the Mississippi, ranging from 
 British Columbia and Assiniboia to Central Mexico, but are not known 
 in California except in the north.

 luteo testaceous; a broad dark brown or blackish median band extends 
 from the vertex between the eyes to the posterior extremity of the 
 pronotum, broadest on the latter and occupying about one-third of it, 
 but sometimes, and especially in southern examples, wholly absent 
 from the pronotum; besides this, another band runs from behind 
 the eye to the anterior margin of the metazona; generally this is 
 comparatively narrow and often obscure, but often sends off streaks 
 of blackish fuscous down the incisures, and is sometimes tolerably 
 distinct and uniformly deep in tint; vertex considerably tumid, well 
 raised above the level of the pronotum, the interspace between the 
 eyes fully half as broad again ( male) or more than twice as broad 
 (female) as the first antennal joint; fastigium strongly declivent, 
 slender, with parallel sides, and rather deeply sulcate; frontal costa as 
 broad as the interspace between the eyes, equal, scarcely sulcate below 
 the ocellus, biseriately punctate above; eyes large, not very prominent 
 even in the male, elongate but no longer than the infraocular portion of 
 the genae; antennae yt j llow, somewhat infuscated apically, fully three- 
 fourths (male) or but little more than two-thirds (female) as long as the 
 hind femora. Prouotum slightly expanding posteriorly, the disk 
 broadly convex and passing by a well rounded shoulder, which only 
 posteriorly forms the semblance of lateral carinae, into the vertical 
 lateral lobes ; median carina scarcely perceptible except on the meta- 
 zona, where it is distinct but not prominent; transverse sulci distinct;

 punctate metazon a. Prostemal spine rather long, erect, subpyramidal, 
 not very blunt, its anterior face vertical ; interspace between mesoster- 
 nal lobes fully twice as long as broad (male) or a little longer than 
 broad (female). Tegniina surpassing a little the hind femora, rather 
 broad, tapering considerably in the apical half, brownish fuscous, with 
 a row of dusky quadrate spots down the proximal half of the discoidal 
 area, but sometimes wholly immaculate. Wings hyaline, glistening, 
 the veins in the apical and anterior regions fuscous. Legs yellow, 
 tinged with dull orange, the hind femora faintly bifasciate above 
 internally, and with the upper exterior cariua black; hind tibiae 
 normally glaucous, paler and dull at the apex, sometimes uniform

 It has also been reported from Garden City, Kansas (Bruner), Regina, 
 Assiniboia (Caulfield), and northern California, abundant (Koebele). 
 
 This species bears a elose general resemblance to M. bivittatus, from 
 which it is nevertheless very distinct. Bruner says, wit a regard to it, 
 that "it never leaves the open country for timbered or low localities 
 where the vegetation is rank," as that and other species do. It is a 
 prairie species. 
 
 Cockerell has given the variety with red hind tibiae a distinctive 
 name. I have seen it from British Columbia, Washington, Oregon, 
 northern California, Idaho, Montana, Nebraska, Kansas, Utah, Nevada, 
 Colorado, and 2s ew Mexico. It appears to be the prevailing if not exclu- 
 sive form in some northern parts of its range. Specimens before me 
 from Wyoming, Iowa, and Texas have blue legs only; both forms occur 
 in Montana, Nebraska, Utah, and Colorado. 
 
 In coloring and markings it is one of the most variable species of 
 Melanoplus known to me, but I have been unable to find grounds for 
 specific distinctions between the various forms, which seem to run into 
 each other completely.

 little and broadly sulcate. Pronotum simple, the metazoua coarsely 
 and faintly punctate, expanding very slightly and a little depressed 
 above anteriorly, on either side; prozona narrowed a little in front but 
 above only; transverse sulci distinct and continuous; median carina 
 slight and confined to the rnetazona, lateral carinae subobsolete. Pro- 
 sternal spine not very long, erect, appressed conical, blunt; interspace

 as broad. Tegmina extending a little (female) or considerably (male) 
 beyond the abdomen. Extremity of male abdomen clavate, hardly 
 recurved, the supraanal plate triangular, considerably longer than 
 broad, bluntly pointed, the sides nearly straight, slightly puckered in 
 the middle; furcula consisting of a pair of sinuous, depressed, conical, 
 pointed projections, diverging at right angles, about half as long as 
 the cerci; cerci forming very simple compressed laminae, the basal 
 three-fifths straight, tapering a little and directed backward and 
 upward, the apical two-fifths also straight, enlarging slightly, keeping 
 the same direction but bent a little inward, the outer surface a little 
 hollowed, the extremity truncate, its corners rounded; subgenital lobe 
 scoop-shaped but slightly produced at the apex, the margin entire. 
 Basal tooth of the lower valves of the ovipositor sharp, triangular, but 
 much broader than long. 
 
 The general color is a dirty cinereous above, a dingy clay yellow 
 below; antennae dull testaceous, becoming somewhat ferruginous 
 toward the tip; a pretty broad and usually distinct, blackish brown or 
 piceous band extends from behind the eye along the upper portion of 
 the lateral lobes across the prozona, and sometimes as a blurred and 
 expanded continuation of it across the rnetazona also. Tegmina 
 brownish cinereous, the anal area sometimes a little lighter, the dis- 
 coidal area enlivened to a greater or less extent, but seldom conspicu- 
 ously, by an alternation of blackish and pallid longitudinal rectangular 
 spots. Hind femora dirty clay brown with dusky incisures, above with 
 median and subapical dusky or dark fuscous patches; hind tibiae 
 red with black-tipped spines, ten to twelve in number in the outer

 The original types of this species are all that I have seen, but it is 
 said by Bruner to be found also in " Kansas, Nebraska, Wyoming, 
 Utah, Nevada, Idaho, Montana, and the Dakotas, along with New

 Mexico." As all the specimens seen from tbese regions which might 
 be referred to this species (and in some instances have been so labeled) 
 prove to belong to M. packardii, I think it probable that some at least of 
 these localities may be wrongly given. The species indeed differs 
 but slightly from M. packardii, and may prove to be merely a varietal 
 form of it dependent upon station, which in this species is in the dank 
 vegetation of river bottoms where M. packardii occurs but rarely. I 
 took a few specimens of the latter, however, in company with the 
 former.

 Melanoplus compacius BRUNEK!, MS. 
 
 A medium-sized species, blackish fuscous in coloring, more or less 
 tinged with ferruginous. Head not prominent, rufo-luteous more or 
 less clouded with fuscous, with a median blackish fuscous stripe above 
 and a postocular piceous band; vertex gently tumid, feebly elevated 
 above the pronotum, the interspace between the eyes considerably 
 broader than (male) or nearly twice as broad as (female) the basal 
 antenual joint; fastigium steeply declivent, sulcate throughout, more 
 deeply in the male than in the female; frontal costa just failing to 
 reach the clypeus, feebly narrowed above but otherwise subequal, as 
 broad as the interspace between the eyes, sulcate at and below the 
 ocellus, biseriately punctate above; eyes not prominent nor large, about 
 as long as the intraocular portion of the genae; antennae red, gradually 
 infuscated apically, in the female more than three-fourths as long as the 
 hind femora. Pronotum stout, gradually enlarging posteriorly, the lat- 
 eral lobes of the prozona with a more or less distinct piceous postocular 
 band, the disk passing into the vertical lateral lobes by a distinctly 
 though slightly angulated shoulder, for mingfeeblelateralcarinae; median 
 carina percurrent but much feebler on the prozona than on the metazona; 
 front margin truncate, hind margin obtusangulate; prozona feebly (male) 
 or distinctly (female) transverse, no longer than the closely punctate 
 metazona. Prosternal spine rather short and rather stout, much 
 appressed, tapering, very blunt; interspace between mesosternal lobes

 punctate with fuscous, especially in the discoidal area where the puncta 
 are aligned with lutescent marks; wings moderately ample, hyaline, 
 the veins pale fuscous, becoming darker anteriorly and apically. Fore 
 and middle femora considerably tumid in the male; hind femora stout, 
 dull testaceous, very obliquely bifasciate with blackish fuscous, except 
 beneath, which is flavous; hind tibiae feebly valgate, bright red. the 
 short black spines with pallid bases, nine to eleven in number in the outer 
 series. Extremity of male abdomen somewhat clavate, a little recurved, 
 the supraanal plate subtriangular with acutangnlate apex, nearly plane 
 surface, apically stepped by a distinct transverse ridge just beyond the 
 middle, the median sulcus broad and shallow in the basal portion, 
 narrow beyond; furcula consisting of a pair of slight, distant, parallel 
 denticulations lying outside the ridges bounding the median sulcus of 
 the supraanal plate; cerci and infracercal plates entirely as in M. con- 
 spersus ; subgenital plate rather narrow, equal, not at all flaring, the 
 apical margin not at all elevated, well rounded, entire. 
 
 Length of body, male, 21 mm., female, 22.5 mm.; antennae, female, 
 10 mm.; tegmina, male, 16.25 mm., female, 17.25 mm.; hind femora, 
 male, 11 mm., female, 12.5 mm 
 
 Two males, 2 females. Dakota (U.S.KM. Biley collection) ; Gordon, 
 Sheridan County, Nebraska, L. Bruner (same). 
 
 This species is closely related to the preceding, from which it differs 
 in the narrowness of the subgenital plate of the male and the 
 difference in the interspace between the mesosternal lobes. Its general 
 resemblance is very close. 
 
 23. TEXANTJS SERIES. 
 
 In this not altogether homogeneous group, the prozona of the male 
 is longitudinal, generally distinctly longitudinal, and the interspace 
 between the mesosternal lobes in the same sex is almost, or fully, or 
 even more than, twice as long as broad. . With the exception of the first 
 species, the hind margin of the pronotum is obtusangulate. The 
 antennae are variable. The tegmina are also variable though always 
 abbreviate, and in most of the species are longer than the pronotum 
 and overlap, but in the first they are shorter and distant. The hind 
 tibiae are red or glaucous and have nine to thirteen spines in the outer 
 series. 
 
 The supraanal plate is triangular with more or less elevated margins 
 and distinct median sulcus; the furcula is reduced to small or even 
 minute denticulations; the cerci are large, constricted in the middle 
 and again expanded, more or less incurved and sometimes again 
 apically bent in the original direction; the subgenital plate is broad, 
 generally produced or elevated apically, the margin entire. 
 
 There are five species, all occurring west of the Mississippi, except 
 one which is found in the upper Mississippi region; of the others two 
 occur in Texas (and one of them in Kansas also), a fourth east of the 
 
318 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL.XX. 
 
 Sierra Nevada in central California, and the last in central Mexico. I 
 have also in my collection another species (No. 351) from Mexico, allied 
 to one of the Texan species, but of which I know only the female, and 
 therefore do not describe. 
 
 This series represents to a certain extent, in brachypterous forms, 
 the robustus series of macropterous species.

 duced ovate, about as long as the head and pronotum together, nearly 
 twice as long as broad, the inner margin rather gently the costal mar- 
 gin considerably convex, the tip roundly pointed. Fore and middle 
 femora somewhat tumid in the male. Extremity of male abdomen 
 clavate, considerably recurved, the supraanal plate triangular, a very 
 little broader than long, pointed, the sides nearly straight; furcula con- 
 sisting of a pair of slight but broad, depressed, angular teeth, their

 face of the body and the tegmina are more or less profusely dotted with 
 very pale fuscous; an oblique, cuneiform, yellow dash, the apex in front 
 and above, follows the ridge of the metathoracic episterna, margined 
 on either side by an equal piceous belt. The hind femora generally 
 partake of the color of the upper surface of the body, but appear darker 
 from being specked with blackish fuscous dots, which generally cluster 
 more or less into two very oblique bands in the middle and beyond the 
 middle, and also margin interruptedly the upper outer carina; hind 
 tibiae red, the apical half of the spines black, these eleven to thirteen, 
 generally eleven, in number in the outer series.

 In this somewhat homogeneous group, the prozona is distinctly 
 longitudinal in both sexes (the female of one species is not known) and 
 nearly or quite half as long again as the metazona, the posterior margin 
 of which is subtruncate or truncate or sometimes very obtusangulate. 
 The interspace between the mesosternal lobes in the male is more than 
 twice, sometimes thrice, as long as broad. The tegmina are very vari- 
 able; one species is dimorphic, having either fully developed tegmina 
 and wings considerably surpassing the tips of the hind femora, or 
 ovate lanceolate overlapping tegmina, acuminate at tip and a little 
 longer than the pronotum; another is macropterous with subequal 
 tegmina, reaching the tips of the hind femora; the other species are 
 brachypterous, but the tegmina are variably shaped, sometimes as 
 in the brachypterous form of the dimorphic species, at others either 
 rounded ovate and attingent, or widely separated and lateral. 
 
 The supraanal plate is triangular, with generally a tolerably plane 
 surface; the furcula is obsolete, subobsolete, or reduced to mere brief 
 denticulatious; the cerci are long, constricted in the middle, but 
 expanding only a little apically, incurved, and bluntly rounded or 
 inferiorly subacuminate at tip; the subgenital plate is always small, 
 distinctly narrower than long, often narrowing apically, and sometimes 
 ends in a tubercle. 
 
 There are five species, most of them widely separated from one 
 another: one occurs in the upper Mississippi valley from the Dakotas 
 to Kentucky, while the others are found respectively in Florida (two 
 species), Texas, and California.

 This is a tolerably homogeneous group, in which the prozona of the 
 male is quadrate or nearly so, varying from a little longitudinal (in one 
 species distinctly longitudinal) to a little transverse, and the interspace 
 between the mesosternal lobes in the same sex ranges from a little 
 longer than broad to twice as long as broad. The tegmina are always 
 fully developed, rarely do not surpass the hind femora, and are more

 or less, generally rather vaguely, maculate or blotched. The hind 
 tibiae are either red or green, usually the former, and have ten to four- 
 teen spines in the outer series. 
 
 The supraanal plate is pretty regularly triangular, the apex never 
 obtusangulate and generally has a median transverse ridge of greater 
 or less distinctness. The furcula is generally a mere triangular tooth 
 shorter than the last dorsal segment, but in one species is wanting and 
 in others forms a pair of slender spines a little longer than the last 
 dorsal segment. The cerci are of moderate width and invariably forked 
 more or less distinctly, sometimes the upper, sometimes the lower fork 
 the longer, or they have a strongly angulate median process beneath, 
 which stands for gdi inferior branch. The subgenital plate is variable, 
 but is generally rather broad (but sometimes very narrow) and gener- 
 ally a little, in one species greatly, elevated apically. 
 
 The species, nine in number, are of small or medium size, occasion- 
 ally a little above the medium. Some species or other of the group has 
 been reported from every part of the United States excepting Alaska 
 and California, and is known also from the immediately neighboring 
 parts of the Dominion of Canada west of the Great Lakes, but none 
 have been reported from Ontario or Quebec, where they doubtless 
 exist, nor from the Lower Mississippi Valley, where they also probably 
 occur; nor is a single species known from any part of Mexico.

 distinctly but not heavily maculate along the discoidal area, rather 
 more distinctly in the female than in the male; wings moderately 
 broad, hyaline, the veins pale fuscous, deepening apically and ante- 
 riorly. Fore and middle femora very little tumid in the male; hind 
 femora of normal length, above and within bimaculate with fuscous, 
 which is ordinarily confined in extent, but when extended takes on the 
 form of very oblique fasciations, developed more on the inner than on 
 the outer face, the latter luteo testaceous more or less infuscated espe- 
 cially along the upper margin, beneath and on lower half of inner face 
 luteous or flavous, the genicular arc fuscous; hind tibiae variable, red, 
 yellow, or green, but always pale and rather dull in tint, the spines 
 black beyond the base, ten to twelve, usually eleven, in number in the 
 outer series. Extremity of male abdomen clavate, recurved, the supra- 
 anal plate triangular, the apex acutangulate, the surface nearly plane, 
 with a shallow median sulcus on the basal three-fourths, formed by 
 parallel and at last united, not very high, rounded, bounding ridges; 
 furcula consisting of a pair of approximate, feeble, triangular denticu- 
 lations overlying these ridges; cerci gently arcuate inward, consisting 
 of a stout, tumid, very rapidly narrowing basal portion, a short, sub- 
 cylindrical, median stem, and an apical furcation which develops two 
 flanges: an upper, inward directed brief finger, hardly longer than 
 broad and blunt tipped; and a long, dowucurved, tapering, pointed 
 apophysis, angulate on its upper margin and reaching far beyond the 
 supraanal plate to the base of the apical elevation of the subgenital 
 plate; the latter moderately broad and equal except for the extreme 
 and abrupt apical elevation of the margin, forming, as viewed from 
 behind, a quadrate truncate plate, mesially appressed, rising above 
 the lateral margins of the plate.

 One of the smallest if not the very smallest macropterous species of 
 Melanoplus known. The general color is a dark griseous, the vertex 
 of the head marked in black and dull yellow in a somewhat radiate 
 fashion, the whole face and sides of head brownish olive or sordid 
 yellow, flecked more or less abundantly with black; the antennae are 
 pale dirty yellow, becoming infuscated toward the tip; behind the eye 
 is a broad black baud, often edged with yellow above, which also 
 traverses the upper half or less of the lateral lobes, confined to the 
 prozoiia, and is often enlivened by a small pale quadrate patch in the 
 center of the lobes; the rest of the latter varies from yellow to brown, 
 palest next the margins; the upper surface of the pronotuin varies a 
 good deal, but is usually griseous, often with a median belt of dirty 
 yellow or ferruginous, edged on the front of the metazona by a pair of 
 oblique, crescentic, longitudinal or converging patches of black. Teg- 
 miua cinereous, with alternate minute blocks of yellow and blackish 
 fuscous in the discoidal area, apically changing to scattered quadrate 
 fuscous dots. Hind femora below straw -yellow, above dark brown, 
 with a pair of conspicuous, very oblique pale bars at the middle and 
 next the base; hind tibiae pale glaucous, occasionally with a faint 
 rufous tinge, becoming paler next the base and straw-yellow at the tip, 
 the spines more or less heavily black-tipped, ten to eleven, rarely 
 twelve, in number in the outer series; hind tarsi yellowish. 
 
 Head rather large, but not elevated, and moderately arched; inter- 
 space between the eyes scarcely broader than the first antenna! joint 
 (male) or broader than the length of the same (female); fastigium 
 steeply dechvent, deeply and roundly (male) or shallowly and flatly 
 (female) sulcate, the lateral margins blunt and either slightly (female) 
 or distinctly (male) divergent and then anteriorly convergent; frontal 
 co3ta broad, nearly equal, slightly broader below than above, tumid 
 (female) or flat (male) above, with a row of puncta on either side, 
 narrowly and rather slightly sulcate at and just below the ocellus; 
 eyes rather large, moderately prominent, a little longer than (male) 
 or about as long as (female) the intraocular portion of the genae;

 antennae about three-fourths (male) or over two-thirds (female) as long 
 as the hind femora. Pronotuin rather uniform, subequal, the metazona 
 broadening slightly, especially in the male, subpunctate; median 
 carina distinct throughout, but much slighter on the prozona than on 
 the metazona; lateral carinae tolerably distinct throughout, but blunt; 
 transverse sulci of prozona distinct throughout, unusually sinuous, not 
 severing the median carina; prozona transverse, occasionally in the 
 male subquadrate, distinctly longer than the metazona. Prosternal 
 spine short, stout, erect, conico-cylindrical, appressed, more so in the 
 female than in the male; interspace between mesosternal lobes half as 
 long again as broad (male) or transverse, but narrower than the lobes 
 (female). Tegmina attaining, generally surpassing a little, the tips of 
 the hind femora, slender, feebly tapering. Extremity of male abdomen 
 clavate, a little recurved, the supraanal plate rounded triangular, the 
 extreme apex excised, fully as broad as long; furcula reduced to a pair 
 of minute and blunt triangular teeth; cerci thickened and tumid at 
 base, immediately narrowing to half tlie width and compressed, almost 
 immediately broadening again, curving inward while they run back- 
 wark and upward, and forking, the upper branch directed upward and 
 inward, nearly as large as the basal expansion, subtriangular, a little 
 longer than broad, compressed and apically rounded; the other arm 
 much longer, nearly as long as the rest of the appendage, slender, 
 tapering, but bluntly pointed and directed backward and inward, a 
 little arched from beneath; subgenital plate narrow and equal except 
 for the abrupt and considerable elevation of the extreme apical margin, 
 which is mesially notched. Basal tooth of the lower valves of the ovi- 
 positor large, triangular, sharp, as long as broad.

 rather slender and subequal, brownish fuscous, more or less distinctly 
 but never heavily maculate with fuscous along the discoidal area; wings 
 moderately broad, hyaline with the faintest possible bluish tinge, the

 pairof divergent, posteriorly enlarging stripes, besides a broad, distinct, 
 piceous, postocular band; vertex somewhat tumid, slightly elevated 
 above the pronotum, the interspace between the eyes hardly so wide 
 as 1 (male) or almosfrtwice as wide as (female) the first antennal joint;

 nence, only slightly more prominent in the male than in the female, a 
 little longer than the infraocular portion of the genae; antennae luteous, 
 slightly infuscated next the apex, about two-thirds (male) or but little 
 more than a half (female) as long as the hind femora. Pronotum with 
 the prozona subequal except for the tumid sides, the raetazoua expand- 
 ing considerably, the sides of the prozona with a broad, piceous, 
 postocular baud, which is sometimes a little maculate or strigose with

 nating series of dark fuscous and luteous quadrate spots along the 
 middle line; wings not very broad, hyaline, the veins fusco luteous. 
 Fore and middle femora very slightly enlarged in the male; hind 
 femora slender, compressed, luteo testaceous, very obscurely and on the 
 sides obliquely bifasciate with fuscous, most distinctly on the upper 
 face, the geniculation more or less infuscated; hind tibiae luteo-testa-

 sides, the apex subrectangulate, the apical third a little tumid and dis- 
 tinctly elevated above the median portion, the median sulcus deep, 
 percurrent. narrow in the middle and expanded at both extremities; 
 furcula consisting of a pair of adjacent, subparallel processes, each of 
 which consists of a tumid base bearing an apical, equal, slender, arcuate 
 projection hardly longer than the base; cerci with asubequal, rectangu- 
 late basal portion, straight but transversely arcuate, more than half as 
 long again as broad, the upper apical corner of which is produced as a 
 slightly twisted rounded subspatulate lobe, hardly longer than broad, 
 incurved and exteriorly sulcate, about two thirds as broad as theba>al

 Of medium size. Head rather small, subcompressed, not elevated, 
 moderately arched; eyes moderately prominent; interspace between 
 the eyes as broad as the length of the basal antenna! joint; fastigiuin 
 very shallow, with moderately sharp but not prominent lateral walls, 
 which give it a subspatulate form; frontal costa rather broad, above 
 slightly tumid, with punctulate sides, scarcely broader below, sulcate 
 at the ocellus and to some degree below it. Prouotuin rather slender, 
 rather uniform but distinctly broadening on the metazona, which is 
 separated from the prozona by a considerable depression and a pretty 
 deep sulcus; metazona rather distinctly punctate; median carina dis

 tinct throughout though slight ; lateral carinae obscure on the prozona, 
 the middle of the prozona tumid on the tipper half of the lateral lobes; 
 transverse sulci of prozona distinct throughout, not severing the median 
 carina. Tegm in a considerably longer than the body. Supraanal plate 
 of male (so far as can be seen on the single specimen in which the parts 
 are somewhat concealed) semiovate, broadly rounded apically, longer 
 than broad; the forks of the furcula slender, aculeate, parallel, approx- 
 imate, about half as long as the supraanal plate; cerci of moderate size, 
 compressed, the basal half tapering considerably, straight as seen 
 laterally, directed backward, the apical half a little incurved, nearly 
 equal, enlarging a little apically and notched at the tip; subgeuital 
 plate haustrate, rounded, entire. Basal tooth of lower valves of 
 ovipositor sharp, triangular, as long as broad. 
 
 The specimens on which this description is based were collected in 
 alcohol, and little can be said of their color; there is a more or less 
 broken black postocular baud crossing the prozona on the upper half 
 of the lateral lobes; the hind femora may have been faintly banded, 
 the hind tibiae were probably red, with black spines, and there is a dis- 
 tinct row of fuscous rectangular spots down the discoidal area of the 
 tegmiua, especially in the female.

 I have never again seen the specimens on which this species was 
 founded, nor any others that could be referred to it. Accordingly, with 
 slight change in the phraseology, I reproduce the original description, 
 to which I may add the following unpublished notes, taken while the 
 specimens were still in my hands: The species has very much the same 
 general appearance as M. femur-rubrum. It has, however, entirely dif- 
 ferent abdominal appendages, as may be seen above, and also slenderer 
 tegmina, in the venation of which it closely resembles M. keeleri. The 
 prosternal spine is not very large, but moderately stout and bluntly 
 rounded at tip, a little appressed, and, on side view, not tapering; the 
 mesosternal lobes are much as in M. 'keeleri. The median carina is more 
 distinct on the metazona than on the prozona; the proportions of the 
 prozona are as in M. keeleri and the whole pronotum almost precisely 
 as in that species, with a little more rounded angle to the hind margin.

 It has also been reported from Staten Island, New York (Davis), New 
 Jersey (Smith), the borders of Lake Michigan, in Indiana (Blatchley), 
 and Nebraska (Bruner), the last, I think, by mistake. 
 
 This species is very closely allied to M. lurldus, but differs in its lack 
 of any projecting part to the furcula. the less divergent forks of the 
 cerci, less elevated, apical margin of the subgenital plate and greater 
 maculation of the tegmiua. 
 
 I first observed this species in Sudbury, Vermont, in August, 1868, 
 abundant in the vicinity of groves in dry upland pastures; compara- 
 tively few M. femur rubrum occurred with them, the latter being found 
 in open sunny spots, and especially in hollows in the lowlands. 
 McNeill, who was the first to find it in the West, says that in Illinois 
 u it is restricted to the tops of bills and tbe sides of ravines which are 
 too barren for pasturage.'' At Provincetown, Massachusetts, I found 
 it at the sandy edges of neglected cranberry beds. According to 
 Blatchley, this species may be found in pairing time u among the leaves 
 and branches of the iron-weed." I found one specimen devouring a per- 
 fectly dry and dead hickory leaf. At the middle of August, in Vermont, 
 the eggs are quite undeveloped, the ovaries lying as mere films on the

 intestines of those dissected. The first pair taken in coitu was found 
 August 16, though in Indiana many pairs were found by Blatchley by 
 the first of August. 
 
 20. KOBUSTUS SERIES. 
 
 In this group the male prozona is quadrate or a little longitudinal 
 and the interspace between the raesosternal lobes of the same sex 
 twice or more than twice as long as broad. The eyes are rather widely 
 separated and the frontal costa broad and equal. The prosternal spine 
 is usually long. The tegmina are fully developed or only a little 
 abbreviated and either feebly spotted, longitudinally streaked or wholly 
 free from markings; the hind tibiae are yellow or red, with from ten to 
 twelve spines in the outer series. 
 
 The supraanal plate is shield-shaped or triangular with feebly con- 
 vex or sinuous sides, and with the surface tolerably flat; the furculais 
 entirely wanting or in one or two instances barely indicated; the cerci 
 are excessively broad and stout, apically greatly expanded and flabel- 
 late, with the apical border either convex or more or less emarginate; 
 the subgenital plate is longer than broad, generally moderately narrow, 
 a little elevated apically and sometimes considerably prolonged, always 
 entire. 
 
 It comprises insects of the largest size only and of a stout and bulky 
 aspect. Five species are known, occurring in the southern half or 
 more of the United States.

 \ The largest of our species of Melanopli and heavy bodied; excepting 
 the hind legs and the lateral lobes of the proiiotum, the general color 
 is a nearly uniform brownish testaceous, becoming paler testaceous in 
 specimens from arid regions; in those from Nebraska, Kansas, and 
 Colorado it is sometimes a blackish green, while in those from Illinois 
 and Indiana it is often of a dark brownish green. The head has some- 
 times a pair of dusky, divergent stripes, passing from the posterior 
 corners of the fastigium backward across the vertex and, when these 
 are present, there are often other but irregular streaks of similar tint 
 on the genae and clouds over parts of the face; the vertex is gently 
 arched, more gently in the female than in the male, with a broad inter- 
 val between the eyes, the fastigium broadly and not very deeply 
 impressed; frontal costa broad but narrower than the interspace 
 between the eyes, percurrent, equal except for a slight expansion below, 
 broadly and shallowly sulcate below (and including) the ocellus, punc- 
 tate; eyes moderately prominent, short, not a great deal longer than 
 broad; antennae fulvo-testaceous, nearly twice as long (male) or fully

 half as long again (female) as the pronotum. Pronotum subequal, the 
 in eta/on a expanding somewhat, the disk of the prozona sometimes (but 
 not always) very feebly tumid, the front margin feebly convex, thehiiid 
 margin obtusely and roundly angulate, more obtusely in specimens 
 from the Pacific Coast than in others, the median carina distinct and 
 sharp on the metazona, less prominent but distinct on the anterior half 
 of the prozona, still less distinct (occasionally subobsolete) between the 
 sulci; prozona subquadrate in both sexes, smooth, divided in the mid- 
 dle, and barely before the middle of the posterior half, by sulci, the 
 principal sulcus bent forward in the middle by the posterior emargina- 
 tion of the prozona, the metazona plane, finely subruguloso punctate; 
 lateral lobes nearly vertical, separated from the disk by a well rounded 
 angle nowhere forming distinct lateral carinae, marked next the upper 
 limit on the prozona by broken blackish patches, frequently reduced 
 to a pair of short, oblique, black dashes, one in either longitudinal half 
 of the prozona, each in a clearer field, and also by the blackening of the 
 sulci in this region; they are sometimes accompanied by slender, 
 oblique, parallel, black lines lower down, the hinder the lower; the 
 pleural incisures are also heavily marked in black. Prosternal spine 
 rather long, conical as seen from the side, bluntly cylindrical as seen 
 from in front, a very little retrorse. Tegmina at least reaching (female) 
 or distinctly surpassing (male) the hind femora, absolutely free from 
 maculation, the narrowest apical portion about half as broad as the 
 broadest subbasal portion; wings pellucid or (in darkest forms) very 
 feebly infurnated, feebly and narrowly opaque along the costal margin, 
 the veins and cross veins mostly brownish fuscous. Fore and middle 
 femora of male heavily bullate, the hind femora stout and rather short, 
 moderately tumid, generally fulvo testaceous, sometimes flavo-testa- 
 ceous beneath, the outer face with alternate, fulvo testaceous and 
 black, narrow, equal fish-bone markings, the black rarely interrupted 
 in the middle, 1 the upper inner face with small basal and large median 
 and postmedian black patches, the genicular arc black on both inner 
 and outer sides; hind tibiae yellow or fulvous (occasionally in California 
 bright coral red), with a postbasal narrow black annulus (in dark 
 specimens more or less infuscated beyond it), the spines black to their 
 very base, ten to eleven, rarely twelve, in number in the outer series. 
 Extremity of male abdomen heavily clavate, the supraanal plate sub- 
 clypeate, obtusely angulate at apex, the margins feebly and broadly 
 elevated and the median portion correspondingly elevated and bearing 
 on its summit a moderately shallow, longitudinal sulcus, tolerably 
 broad and subequal on the basal half, narrowing and with falling walls 
 apically; furcula completely absent or indicated only by a thickening 
 of the last dorsal segment at their proper position; cerci very large 
 
 1 In the dark forms the black markings sometimes run together and cover the 
 A\ hole face, partially interrupted near the middle and in the middle of the basal 
 half, with fulvous.

 and coarse, laminate, boot- shaped, the basal half subequal, punctate 
 and straight, beyond expanding and at the same time feebly bifurcate, 
 the upper fork as long and more than half as broad as the base, feebly 
 incurved, strongly upcurved, apically tapering slightly and well 
 rounded, the lower fork at right angles to it, forming only a rounded, 
 downward and posteriorly projecting lobe, so that the apical margin 
 of the whole is deeply and roundly emarginate below, the whole sur- 
 passing a little the supraanal plate; infracercal plates wholly obscured ; 
 subgenital plate short and broad, scarcely so broad apically as long, 
 the apical margin thickened, but hardly otherwise either elevated or 
 prolonged, entire; upper valve of ovipositor abruptly upturned apic- 
 ally and sharply acuminate, the upper outer carina feebly serrate.

 It appears from this that it inhabits the Mississippi Valley from as 
 far north as latitude 43 to the Gulf, and the region to the west as far 
 as the Pacific, from a somewhat lower latitude to central Mexico. I 
 do not think it occurs above 6,000 feet. One can not but question the 
 accuracy of the statement that it occurs in New Jersey, 1 as it has never 
 been reported elsewhere east of the Alleghanies, and if found there 
 would also occur farther south; so large an insect and so distinc from 
 others found there would hardly have escaped notice by entomologists 
 of the eastern seaboard in Maryland and Virginia. 
 
 The oviposition and arrangement of eggs in the egg-capsule of this 
 insect, as well as its parasites, are described by Eiley in the first Report 
 of the United States Entomological Commission, and with its life-his- 
 tory are later summarized by him, as follows : 
 
 In the vicinity of St. Louis, Missouri, the tirst specimens of this locust were 
 observed to become winged July 19. Eggs were laid September 9. As a deviation 
 from the usual egg-laying habits of the genus . . . the eggs are sometimes very 
 numerously placed under bark of logs that have been felled on low lands. The eggs 
 of this species, unlike those of spretus, atlanis and fcmur-rnbrum, are not quadri- 
 linearly but irregularly arranged. . . . The head ends of the eggs in the pod point 
 mostly outward. One hundred and seventy-live eggs have been counted in a single 
 
 lllilSS. 
 
 Mr. Coquillett has made some interesting observations [in California]. . . . They 
 acquired wings from the last week in June to the last week in July and began lay- 
 ing eggs July 23. A single female occupied 75 minutes in depositing an egg-mass. 
 The situation chosen for egg laying was invariably the edge of one of the basin-like 
 hollows [for irrigation?] at the foot of a tree. This locust is not easily startled, 
 and its ordinary flight is rather heavy, and sustained only for a distance of 12 to 20 
 feet. 
 
 According to Thomas and Kiley, this insect, is occasionally seen fly- 
 ing at considerable heights and apparently migrating, though these are 
 rare occurrences. It certainly is occasionally one of the most destruc- 
 tive pests in the West, particularly in Kansas, Missouri and Illinois, 
 and it has been noted as injuring grass, alfalfa, Indian corn, beets, 
 orchard trees, mulberry, poplar and catalpa trees, and even grape 
 vines; also dahlias, hollyhocks and other garden flowers have been 
 specified as its food, not to mention the rag weed, Ambrosia trifida. 
 
 'Since this was sent to the printer I have seen specimens from Camden County, 
 New Jersey, in the collection of the American Entomological Society.

 Professor Lawrence Bruuer gives the following excellent summary of 
 its destructi ven ess and habits : 
 
 This insect has very frequently multiplied in such numbers in limited areas over 
 its range as to do considerable injury to cultivated crops growing upon low, moist 
 ground; and has even been known very frequently to spread over higher and dryer 
 lands adjoining these, its customary haunts. It is one of the few species of locusts 
 that has thus far shown a tendency toward civilization. This it has done readily, 
 since its habits are in unison with the cultivation of the soil. It is only since the 
 settlement of the country where it originally occurred that it has multiplied so as 
 to become sufficiently numerous to become a serious pest. . . . 
 
 The eggs . . . are laid in cultivated grounds that are more or less compact, pref- 
 erably old roads, deserted fields, the edges of weed patches, and well-grazed pastures 
 adjoining weedy ravines. Egg laying begins about the middle of August and con- 
 tinues into October, varying of course, according to latitude and climatic conditions. 
 Usually but not always, only a single cluster of eggs is deposited by each female. 
 Frequently there are two, and in extreme cases perhaps even three, of these clusters 
 deposited by a single female.

 have no doubt from the study of the larger material now at hand that 
 it is the same as Cal. robustus, described at the same time and place.

 (Plate XXIV, fig. 3.) 
 
 Brownish-ferruginous, the top of head and prozona very faintly dotted 
 with fuscous. Head gently tumid above, the interspace between the 
 eyes broad, but distinctly narrower than the frontal costa, the fastigiuni 
 most feebly depressed, running without break into the frontal costa, 
 which is broad, equal, shallowly sulcate at and below the ocellus, punc- 
 tate on either side; eyes pretty large, rather elongate, not very promi- 
 nent; antennae fulvous, becoming a little infuscated apically, almost as 
 long as the hind femora in both sexes, being relatively almost as long* 
 in the female as in the male. Pronotum enlarging slightly posteriorly, 
 at least in the female, the disk very flatly tectate, the median carina 
 very slight and subequal throughout, the lateral carinae merely forming 
 blunt angles separating the disk from the lateral lobes, the front margin 
 scarcely convex, the hind margin broadly and roundly angulate ; disk of 
 prozona feebly longitudinal, sparsely feebly and shallowly punctate lat- 
 erally, about a fourth longer than the finely and closely punctate meta- 
 zona, minutely einarginate in the middle posteriorly; lateral lobes 
 marked precisely as in M. clypeatus. Prosternal spine rattier long, 
 slightly retrorse, cylindrical, but a little enlarged on the apical half. 
 Tegmina not much shorter than the abdomen, but not nearly reaching 
 the tip of the hind femora, testaceo cinereus in the anal field, the rest 
 fuscous, with dark fuscous flecks (male) or blotches (female) in tbe dis- 
 coidal area; wings impure hyaline, with very pale brown veins and cross 
 veins, becoming more and more fuscous in the upper half, especially 
 toward the apex. Fore and middle femora only a little tumid in the 
 male, uniform in color; hind femora long and rather stout and tumid,

 the inner face twice barred with black, which sometimes shows feebly 
 above, and appears again on the outer face, but diffused, subconflueut, 
 and crossed by the pallid angnlate incisures; inferior face red; genicu- 
 lar arc black on both sides; hind tibiae red, with a subbasal, narrow, 
 fuscous annulus, the spines black to their base, twelve in number in the 
 outer series. Extremity of the male abdomen roundly clavate and 
 upturned, the supraanal plate triangular and tolerably flat, but with a 
 deep basal median sulcus reaching more than half way to the tip with 
 pretty high and sharp bounding ridges, fading apically; furcula wholly 
 wanting; cerci stout, heavy, and incurved, narrowing considerably 
 toward the middle, then very rapidly expanding and furcate, the upper 
 lobe longer than the lower and more equal, well rounded apically, 
 directed sharply upward, the lower triangular, bluntly pointed, and 
 turned but little downward, the apical margin of the whole deeply and 
 angularly excised, scarcely surpassing the supraanal plate; infracercal 
 plates just longer than the supraanal plate; subgenital plate moder- 
 ately narrow, the apex a little and angularly elevated, scarcely pro- 
 longed, entire.

 27. BIYITTATUS SERIES. 
 
 This group is nearly related to the robustus series ; the male prozona 
 is more or less distinctly longitudinal, and the interspace between the 
 mesosternal lobes of the same sex nearly or more than twice as long as 
 broad; the eyes are rather widely separated, and the frontal costa 
 broad and equal. The prosternal spine is rather long and generally 
 slightly retrorse. The tegmina are fully developed, at least as long as 
 the hind femora, without spots or, rarely, very feebly marraorate, but 
 sometimes with a light stripe dividing the dorsal and lateral faces and 
 extending across the pronotum. The hind femora are longitudinally 
 striped on the outer face or unmarked, the hind tibiae usually red, 
 rarely purplish, with ten to thirteen spines in the outer series. 
 
 The supraanal plate is much as in the robustus series; the furcula is 
 present as small but coarse lobes, and the cerci are much as in the 
 robustus series, but less extravagantly developed; the subgenital plate 
 is longer than broad, generally moderately narrow, somewhat elevated 
 and sometimes thickened apically, hardly prolonged, and always entire. 
 
 It comprises insects of a large or a very large size, with heavy bodies 
 and poor in flight. Five species are known, and among them they cover 
 our entire territory, from Atlantic to Pacific and from Central Mexico 
 to the Saskatchewan and Hudson Bay. It comprises two of our com- 
 monest species.

 fuscous above except in widening Havens stripes which follow the outer 
 margins of the fastigium and cross the head to the lateral carinae of 
 the pronotum; vertex gently tumid, the interspace between the eyes 
 broad, almost or quite as broad as the frontal costa, the fastigium plane 
 or rarely, in the male, very feebly briefly and broadly sulcate, passing 
 insensibly into the frontal costa; the latter broad, subequal but feebly 
 and broadly narrowed above, plane or feebly sulcate below, percurrent; 
 eyes moderately prominent in the male, moderate^ large, not very 
 elongate even in the female, scarcely longer than the intraocular portion 
 of the geuae; antennae fulvous, becoming fuscous apically, as long 
 (male) or hardly more than two-thirds as long (female) as the hind 
 femora. Pronotuin subequal, but barely expanding on the metazona 
 (male) or distinctly though not greatly expanding from the posterior 
 sulcus of the prozona (female), the disk nearly plane but slightly convex, 
 separated from the sub vertical lateral lobes by a tolerably pronounced

 punctate metazona; front margin truncate or barely convex, hind margin 
 broadly rotundato-angulate; disk dark brownish fuscous, more or less 
 dark olivaceous in life, the lateral carinae more or less heavily marked 
 with a flavous stripe upon the disk, next to which the lateral lobes are 
 darkest, gradually fading below, but often forming a blackish lateral 
 stripe, which extends from the hinder edge of the eyes across the pro- 
 zona and dies out upon the metazona; at their lowest margin the 
 lateral lobes are of nearly the same color as the under surface, and 
 occasionally the whole of the lateral lobes are uniformly dull flavous or 
 flavo-testaceous, the flavous stripe of the lateral carinae marked only 
 by its brightness and a feeble blackish external edging. Prosterual 
 spine rather long and a little retrorse, conical as seen laterally, cylin- 
 drical or conico-cylindrical from in front. Tegmina reaching or a little 
 surpassing the hind femora, rarely a little less in the female, tapering 
 very regularly and gradually from the subbasal expansion, strongly 
 and uniformly rounded at tip, with a flavous stripe along the anal vein, 
 elsewhere fuscous, deepest in color in the discoidal area, free from 
 mottling; wings hyaline with the feeblest flavous tinge, the veins and 
 cross veins pallid green but becoming more and more fuscous toward 
 the apex. Fore and middle femora fulvo-olivaceous, a little iufuscated 
 above and apically; hind femora rather long and only moderately stout, 
 very variable in ground color but usually lighter than the general color 
 of the body, sometimes much lighter, sometimes without stripes or 
 bands except an infuscation along the upper carina of the outer face, 
 at others iufuscated over most of the upper half of that face, rarely with 
 three distinct, broad, black patches along the inner half of the upper 
 face, basal, median, and postmedian, the geuicular arc always black or

 the spines black, at extreme base pale or reddish, ten to thirteen in 
 number in the outer series. Extremity of male abdomen feebly clavate, 
 well rounded, upturned, the supraanal plate subclypeate, nearly flat, 
 with a narrow and very deep median suleus, fading just before the tip, 
 bounded by high sharp walls, between which and the lateral margins 
 is a broad and shallow trough; furcula consisting of a pair of slight 
 triangular lobes broader than long, separated by their own breadth; 
 cerci very stout, large and broad, laminate, externally convex, the 
 basal half narrowing gently, beyond the middle at once expanding into 
 two lobes : an upper, nearly as long as the basal half of the cerci, directed 
 upward and backward, forming an ovate pad; and a lower, brief, tri- 
 angular denticle, broader than long, the apical margin more or less 
 distinctly emargiiiate below between them; infracercal plates shorter 
 than the supraanal plate, but expanding a little laterally beyond its 
 margins; subgenital plate moderately narrow and subequal, at apex a 
 little elevated and prolonged, with a subdued tubercle.

 It has also been reported from Hudson Bay (Walker); Quebec, 
 Canada (Provancher), and Carolina (Burmeister, Saussure). Its range 
 in the eastern part of the country is therefore from Hudson Bay to 
 North Carolina, on the Pacific Coast from Vancouver to southern 
 California, while in the interior, south of Canada, it occurs in less 
 abundance as far south as latitude 40 or thereabouts. 
 
 An examination of three females in Vermont in the middle of August 
 showed thirty-nine eggs in the ovaries on one side and thirty on the 
 other of the first; forty-five on one side and forty-two on the otherof the 
 second; and thirty eight on each side of the third, the total number of 
 eggs varying from sixty-nine to eighty-seven. A fourth female had no 
 eggs in the ovaries, but the abdomen was filled with a filariau worm 
 at least two feet long; the eggs are pale yellow. 
 
 This insect is very fond of perching by the roadside on the broad 
 leaves of Inula helenium, sunning itself.

 It has also been reported from Tennessee and Mississippi (Thomas), 
 Nevada (Riley), Idaho (Thomas, Millikeu), Souris River, Alberta, Can- 
 ada (Scudder), Grand Rapids, NW. T. (Nutting), and Victoria (Fletcher) ; 
 also, possibly, from Mexico (Saussure). It therefore probably ranges 
 from southern Canada to the Gulf, but is unknown along the Atlantic 
 Seaboard, and wholly unreported from the Pacific Slope south of Wash- 
 ington, (unless, as above, in Mexico) and it hardly ranges as far north 
 as M.femoratm. 
 
 Brunei* in one of his accounts of this species says it is "a lover of 
 rank and succulent vegetation, such as is found upon bottom lands, 
 along the edges of cultivated fields, at the margins of woodlands and 
 on the shaded mountain slopes." When "it develops in large num- 
 bers, then these haunts are forsaken, to a greater or less extent, and it 
 spreads over cultivated fields, eating the choicest of everything." In 
 Iowa, Mr. J, A. Allen found it common on dry prairies, as well as in 
 moist sloughs on tall grass. 
 
 It seldom develops any marked migratory propensity and its egg- 
 laying habits " differ considerably from those of the smaller migratory 
 species, insomuch as but one or two clusters or pods are deposited by 
 a single female. Nevertheless, just as many eggs are laid by each 
 female insect. These eggs are deposited in prairie sod or any compact 
 soil in the vicinity of the regular haunts or feeding places. Old roads 
 and closely cropped pastures, when located handily, are favorite resorts 
 for the heavily laden females when attending to this mission of theirs." 
 (Bruner.) 
 
 Its destructiveness appears to be mainly confined to grass, grain, 
 and garden vegetables. It appears in the winged state the last of 
 June or early in July, but eggs are not laid until late in August; 
 sixty-two to seventy-two eggs have been counted in the egg pods by 
 Donald Gunn in Manitoba. 
 
 Blatchley has taken the male of this species in coitu with 3f. femo- 
 ratus, and considers them the same species, as do many others. The 
 range of the two species, which are certainly very closely allied, differs 
 to a considerable extent, though both are found over a large extent of 
 territory side by side; one is a seaboard and northern form, the other 
 an interior species. Besides the differences in the hind tibiae, which 
 rarely cause hesitation in attempting to separate them, there are slight 
 'differences which I have attempted to state, in the abdominal append

 ages and in the tegmiua, besides some distinction in the general 
 coloration. 
 
 The specimens from Grand Junction, Colorado, mentioned above as in 
 B rimer's collection, are short winged and indicate occasional dimorphism 
 in this species.

 Although Thomas's description of C. yarrowii was based upon a 
 female only, I am tolerably confident that this species is to be referred 
 to it; it certainly fits it better than any known to me, and its reference 
 here was suggested to me by Professor Bruner. Thomas gave no locality 
 beyond "found in the collection," which was made in "portions of 
 Nevada, Utah, California, Colorado, New Mexico and Arizona." He 
 afterwards mentions it as "probably from Arizona, but possibly from 
 Nevada," without giving reasons. From all that appears it might have 
 come as well from Colorado or Utah.

 apical flabellatiou, nearly half as broad again as the extreme base, 
 expanding more above than below, the apical margin broadly convex, 
 the whole considerably surpassing the supraanal plate; infracercal

 28. PUNCTULATUS SERIES. 
 
 This group is composed of species with prominent head and rapidly 
 declivent fastigium, and, in the male, very prominent eyes. The joints 
 of the antennae are unusually long. The prouotum is rather short and

 in front rather flaring to receive the head, the prozona quadrate (male) 
 or distinctly transverse (female), the prosternal spine short, conical, 
 and erect, and the interval between the mesosternal lobes relatively 
 broad. The tegmina are fully developed, longer than the hind femora, 
 maculate over their whole breadth. The hind femora are twice rather 
 narrowly belted with black, and the hind tibiae red, more or less 
 obscured. 
 
 The supraanal plate of the male is triangular, the furcula very slight 
 or wanting, the cerci very large and broad, immensely expanded api- 
 cally and flabellate, with convex apical margin, the subgenital plate 
 very much prolonged and greatly elevated apically. 
 
 The insects are of medium or large size and dark color, much mot- 
 tled, and live as far as known only on coniferous trees. Two species 
 are known, one from the Southwest, the other over a large part of the 
 country east of the Rocky Mountains.

 over but little space, to receive the head, the front margin faintly con- 
 vex, the hind margin broadly angulate, the angle broadly rounded, the 
 whole brownish fuscous or yellowish brown, more or less mottled 
 (except on the metazona) with olivaceous or dull flavous and with fus-

 or subquadrate dark fuscous spots, less abundant in the apical third, 
 but not confined at all to the discoidal area; wings smoky pellucid, 
 becoming feebly infuscated apically, the veins and cross-veins mostly 
 blackish fuscous. Fore and middle femora luteo-ferruginous, flecked 
 with dark olivaceous or fuscous; hind femora varying from, sordid 
 luteo-fuscous to dull pale olivaceous, rather narrowly and completely 
 bifasciate with black, forming unusually regular transverse bands, the 
 whole apex blackish fuscous or black; hind tibiae plumbeo-fuscous at 
 extreme base, followed by a very narrow black annulus and this by a 
 broader pale annulus, beyond which the tibiae are dull red, obscured 
 above, excepting at apex, and sometimes on the sides for a similar and 
 beneath for a brief distance, with fuscous, often broken into flecks, 
 the whole pilose above; spines black nearly or quite to their base, 
 ten to twelve in number in the outer series. Extremity of male abdo- 
 men feebly clavate, much upturned, the supraaual plate broad, triangu- 
 lar, with nearly straight lateral margins, acutangulate tip (too nearly 
 rectangulate in our figure), with a broad and rather shallow median 
 sulcus, interrupted beyond the middle, and in the basal half bounded 
 by moderately high walls; furcula composed of a pair of slight trian- 
 gular projections at the inner angles of the divided last dorsal segment, 
 overlying the ridges of the supraanal plate ; cerci large, subequal on the 
 basal two- fifths or more, then abruptly expanding into a transverse 
 apical flap, twice as broad as the base, the expansion almost wholly on 
 the upper side and at right angles to the basal portion, the apical 
 margin broadly convex, but below emarginate to form a denticulation 
 of the lower posterior angle of the flap, the whole gently incurved 
 and surpassing the supraanal plate ; iufracercal plates wholly concealed 
 beneath the supraanal plate; subgenital plate moderately broad, very 
 greatly extended and abruptly elevated at the extreme apex. 
 
 Length of body, male, 30 mm., female, 44 mm.; antennae, male, IS 
 mm., female, 16.5 mm.; tegmiua, male, 26 mm., female, 31 mm.; hind 
 femora, male, 16 mm., female, 21 nun. 
 
 Six males, 2 females. Dallas, Texas, Boll (U.S.KM. Kiley collec- 
 tion; S. H. Scudder); Gulf coast of Texas, Aaron; Arizona, Schaupp 
 (L. Bruner). 
 
 This species is certainly very closely allied to M.punctu latus, which 
 not only occurs with it, but over a much wider extent of country; it is 
 a much larger insect and differs in several points in the abdominal 
 appendages of the male, though it is possible that the two should be 
 looked upon as races of a single species.

 Dark brownish fuscous much mottled with blackish and often tinged 
 with dull olivaceous, beneath ferrugineo- testaceous. Head varying 
 from pale dull olivaceous to f err ugineo- testaceous, irregularly mottled 
 with blackish fuscous and with a blackish band behind the eyes and a 
 widening median stripe of the same upon the summit; vertex tumid; 
 fastigium rapidly declivent, sulcate throughout, the margins much 
 raised between the eyes, which are separated by a space less than the 
 width of the frontal costa; the latter prominent above, moderate in 
 breadth, subequal, sulcate below the ocellus, sparsely punctate through- 
 out, each point marked by a dark olivaceous dot; eyes large and in the 
 male very prominent, in both sexes much longer than the infraocular 
 portion of the genae; antennae varying from fusco luteous to fusco- 
 ferruginous, much longer (male) or a little or no shorter (female) than 
 the hind femora. Pronotum subequal, widening a little at the metazona 
 in the female, slightly flaring in front to receive the head, especially in 
 the male, varying from luteo-testaceous to brownish fuscous, often 
 much flecked and punctate with black or blackish fuscous, the lateral 
 lobes more heavily marked above with black on the prozona, forming 
 generally a broken or maculate band; front and hind margin as in

 M. arboreus; prozona quadrate (male) or distinctly transverse (female), 
 not more than a third (male) or scarcely (female) longer than the 
 inetazona, the feebly tumid disk passing insensibly without lateral 
 carinae into the lateral lobes, though these are sometimes visible in the 
 posterior section as on the metazona ; median carina occasionally distinct 
 through out, but always feebler and sometimes very feeble on theprozona; 
 metazona closely ruguloso-punctate. Prosternal spine short, conical, 
 erect ; interval between mesosternal lobes su bquadr ate (male) or distinctly 
 transverse, but narrower than the lobes themselves (female). Tegrnina 
 somewhat surpassing the hind femora, very gradually tapering to a 
 well-rounded apex, fusco-testaceous, sprinkled with moderately large 
 roundish or quadrate fuscous spots; wings pellucid, with a feeble 
 greenish-yellow tinge, feebly infumated apically where the veins and 
 cross veins are blackish fuscous. Fore and middle femora luteo- or 
 olivaceo-testaceous heavily flecked with black, showing a tendency to 
 form a triple belting; hind femora similar, the black forming mod- 
 erately narrow basal, preinedian, postraedian, and apical belts, which 
 do no not touch the coralline under and inner surfaces, except the latter 
 in a partial way; hind tibiae dull red, with a postbasal obscure flavous 
 annulus, before which they are sometimes blackened, and beyond which, 
 above and on the sides, often flecked or suffused with plumbeo-fuscous, 
 the serial space between the spines often dull luteous, the whole pilose; 
 spines black nearly or quite to their base, except on the inner side, ten 
 to twelve in number in the outer series, none arising very near the base of 
 the tibiae. Extremity of the male abdomen scarcely clavate, somewhat 
 upturned, the supraanal plate triangular, with convex lateral margins 
 and subrectangulate apex, its median sulcus terminating abruptly in 
 the middle, rather broad, somewhat shallow, bounded by rather sharp 
 walls; furcula entirely wanting; cerci large, broad, the basal half or 
 less subequal, exteriorly convex and punctate, beyond abruptly expand- 
 ing to nearly double the width in exactly opposite directions, consider- 
 ably more above than below, but otherwise symmetrical, the apical 
 margin angulato-convex, the whole gently incurved; infracercal plates 
 surpassing the sides of the supraanal plate only at the extreme base 
 and slightly; subgenital plate moderately broad, apically abruptly 
 elevated to a considerable degree and thickened, but only a little 
 prolonged.

 New York (Davis) ; Ocean County, New Jersey (Smith) ; Ohio (Thomas) ; 
 Galesburg, Knox County, and Urbana, Champaign County, Illinois 
 (McNeill), and eastern Nebraska (Bruner). 
 
 Bruner reports it from oak groves and Smith on cranberry bogs, but 
 Beutenmiiller has found that it lives 011 pine trees. Blatchley found it 
 in the depths of a tamarack swamp, and says it is not an active insect, 
 "usually, after one or two short leaps, squatting close to the earth, and 
 seemingly depending upon the close similarity of its hues to the gray- 
 ish lichens about it to avoid detection." Others have since found it on 
 coniferous trees, and these are, apparently, its proper station. 
 
 24. PHOETALIOTES, new genus. 
 , aroamer.) 
 
 Body elongate, rather slender, a little compressed, very feebly pilose, 
 including faintly the tegmina and legs. Head large, full, prominent, 
 relatively elongate, nearly half as long again as the long prozona, the 
 space behind the eyes fully half as long as the breadth of the eyes, the 
 genae a little tumescent, the head apart from the eyes slightly broader 
 than the pronotuin; vertex prominent and well arched both longi- 
 tudinally and transversely; face a little oblique; eyes rounded broad 
 oval, moderately prominent, subtruncate anteriorly, moderately dis- 
 tant, somewhat farther apart than the greatest width of the frontal 
 costa; fastigium very faintly sulcate, almost plane; frontal costa promi- 
 nent, markedly narrower above than below the ocellus; antennae 
 slender, moderately long, but shorter than the hind femora, though fully 
 twice as long as the prorioturn. Pronoturn of moderate length, faintly 
 subsellate but otherwise equal, feebly flaring in front to receive the head ; 
 disk rounded subtectate, with broadly rounded very indistinct lateral 
 carinae, and a sharp, equal, and percurrent median carina; prozoua 
 longitudinal, nearly half as long again as the inetazona, with indistinct 
 transverse sulci; front margin subtruncate, hind margin extremely ob- 
 tusangulate. Prosternal spine rather large, erect, conical, blunt; meso- 
 and metastethia together much more than twice as long as broad; 
 
NO. 1124. EE riSIOX OF THE MELAXOPLISC UDDER. 377 
 
 interspace between rnesosternal lobes much (male) or a little (female) 
 longer than broad, the metasternal lobes attingeiit (male) or approxi- 
 mate (female) ; portion of metasternum behind the lobes about twice 
 as broad as long and about half as broad as the greatest breadth of 
 the metasternum. Tegmiua either abbreviate, broad lanceolate, acumi- 
 nate, attingent, slightly longer than the pronoturn, or fully developed, 
 surpassing the hind femora, rather broad and equal, well rounded at 
 tip. hardly tapering in the distal half, at a distance from the apex 
 equal to the breadth of the tegmina as broad as the metazona, the 
 intercalaries and cross veins of the discoidal area everywhere few, the 
 venation in general loose, irregular, and ill-defined, the humeral vein 
 broadly sinuous, terminating on the costal margin at least as far before 
 the apex as the breadth of the tegmina, nowhere running closely par- 
 allel to the costal margin nor gradually merging into it, the area inter- 
 calata not reaching the middle of the tegmina. Hind femora long and 
 slender, the genicular lobes pallid with a transverse basal fuscous 
 stripe, the hind tibiae glaucous, sometimes yellowish, with eleven to 
 thirteen spines in the outer series. Abdomen compressed, mesially 
 carinate, apically clavate and recurved in the male, the subgenital 
 plate narrow and long, with lateral margins ampliate at base, the 
 apical margin mesially pinched but not elevated, the apical face with 
 no subapical tubercle; furcula delicately developed; cerci compressed 
 styliform, rather small; ovipositor of female normally exserted. 
 
 This genus is very closely related to Melanoplus, from which it is to 
 be distinguished by its large tumid head and subsellate equal prono- 
 tum, as well as by its substyliform cerci, though the last characteristic 
 is found in some degree in a couple of species of Melanoplus. The 
 neuration of the tegmina, when the latter are developed, also differs to 
 a certain degree, pointed out in the descriptions. Bruner ' has already 
 expressed the opinion that this type should be generically dissociated 
 from other Melanopli. 
 
 A single species is known, found in the western Mississippi basin 
 and beyond its latitudinal limits from Alberta to Mexico.

 Fu'sco-testaceous, flavous beneath. Head navo-testaceous, in fresh 
 specimens more or less fusco-olivaceous, much infuscated above, with a 
 broad piceous postocular band, and often with a pair of divergent fus- 
 cous or ferrugineous stripes on the summit: vertex very tumid, dis- 
 tinctly elevated above* the level of the pronotum, the interspace between 
 the eyes twice (male) or thrice (female) as broad as the first antenual 
 joint j fastigiuin rather rapidly declivent, with scarcely perceptible sul- 
 cation ; frontal costa not nearly reaching the clypeus, much broader 
 below than above the ocellus, the change rather abruptly effected and 
 more striking in the female than in the male, at its broadest consider- 
 ably narrower than the interspace between the eyes, distinctly impressed 
 at the ocellus, and in the male sulcate below it, punctate throughout, 
 above biseriately; eyes moderately large, rather prominent, with no 
 great difference between the sexes, fully as long as (female) or distinctly 
 longer than (male) the infraocular portion of the geuae; antennae 
 testaceous, feebly infuscated apically, about four-fifths (male) or three- 
 fifths (female) as long as the hind femora (but in southern examples of 
 P. n. nebrascensis relatively longer). Pronotum equal, except for being 
 faintly subsellate, especially in the male, the disk ferrugineo-fuscous, 
 rounded subtectate, passing by a very broadly and uniformly rounded 
 shoulder, forming a semblance of blunt lateral carinae, into the ante- 
 riorly feebly tumid vertical lateral lobes, which are more or less tiavous 
 below, and above are marked on the prozona with a very broad piceous 
 postocular baud, generally broader on the posterior section and occa- 
 sionally broken there; median carina sharp but not high, equal, per- 
 current; front margin subtruncate, hind margin very obtusaugulate, 
 in the female often rotundato-obtusaugulate; prozona distinctly longi- 
 tudinal in both sexes, sparsely and shallowly and sometimes very 
 obscurely punctate, nearly half as long again as the densely and finely 
 punctate metazona. Prosternal spine rather long, erect, conical, blunt; 
 interspace between mesosterual lobes about two and a half times longer 
 than broad (male) or about half as long again as broad (female). Teg-

 rounded, ferrugineo-testaceous in the basal half, beyond subhyaline 
 with fusco-testaceous veins and cross veins (P. n. volucris, Plate I, fig. e) ; 
 wings in the latter form about as long as the tegmina, moderately 
 broad, hyaline with fusco-olivaceous or fusco-ferrugiuous veins becom- 
 ing increasingly infuscated apically. Fore and middle femora a little 
 tumid in the male; hind femora flavo-testaceous, generally more 
 or less infuscated or fusco-olivaceous in the upper half of the outer 
 face, the inner side and outer carina of the upper face and upper 
 limit of the inner face more or less distinctly and rather narrowly 
 bifasciate or bimaculate with fuscous; lower face flavous sometimes 
 deepening into roseate; upper genicular lobe and base of lower genic- 
 ular lobe blackish fuscous; hind tibiae usually glaucous, sometimes 
 lighter, sometimes darker, occasionally yellowish, with a subbasal black- 
 ish annulus and the apex fuscescent or flavescent, the spines black

 in the outer series. Extremity of male abdomen feebly clavate, a little 
 recurved, the supraanal plate triangular with slightly convex sides and 
 feebly acutaugulate apex, the median sulcus rather broad and equal, 
 reaching only the middle of the plate and there fading abruptly, the 
 moderately high walls terminating against a feebly transverse plica; 
 furcula consisting of a pair of very slender and brief needles overlying 
 the submedian ridges of the supraanal plate, not nearly so long as the 
 last dorsal segment ; cerci compressed substyliform, moderately broad 
 at base, tapering more rapidly in the basal than in the apical half, 
 bluntly acuminate at tip and about as long as the supraanal plate; 
 subgenital plate narrow and apically narrowing slightly, the lateral 
 and apical margins in about the same plane, the apical margin laterally 
 compressed niesially, so as to simulate an apical tubercle, entire.

 to be found at Cordova, Illinois, only " in a large orchard on the east 
 side of a high hill." 
 
 P. n. volucris has been seen by me from Montana, Wyoming, Nebraska, 
 Texas, Arizona, and Mexico; P. n. nebrascensis from all the general 
 regions mentioned excepting Montana, Wyoming, and Arizona. 
 Bruner long ago pointed out the dimorphism. The antennae of south- 
 ern examples are relatively longer than in those from northern stations, 
 at least in the form P. n. nebrascensis.

 rent, the lateral carinae distinct but blunt, the prozona only about a 
 third (or less) longer than the metazona, the hind border of latter

 obtusely and bluntly angulate; lateral lobes vertical, their lower border 
 very obtusely angulate in the middle. Prosternal spine prominent, 
 subcylindrical, bluntly pointed, laterally compressed at the base, at 
 least in the male; mesosternal lobes narrowly separated in both sexes; 
 metasternal lobes subattingent (male) or as distant as the mesosternal 
 lobes (female). Tegmina and wings variable, but at least as long as 
 the pronotum. Hind femora reaching or generally surpassing the tip of 
 the abdomen, moderately stout but tapering very regularly, unarmed 
 above, the inferior geuicular lobes produced but apically rounded, 
 marked at base with a transverse dark bar; spiued margins of hind 
 tibiae smooth, scarcely dilated toward the tip, provided on outer margin 
 with nine to thirteen, generally eleven, spines, the larger number being 
 more common in the female. Subgenital plate of male short, transverse, 
 of subequal width throughout, more or less tumid, the lateral margins 
 ampliate at the base; anal cerci of male long, laminate, subclepsydral 
 in shape, incurved; edges of inferior valve of ovipositor smooth. 
 
 This genus bears a close general resemblance to the gerontogeic 
 genus Oxya, but differs strikingly from it in the separated metasterual 
 lobes of the female, the blunt tips of the inferior genicular lobes of the 
 hind femora, the smooth edges of the hind tibiae and the absence of 
 the terminal spine of the outer series of the same. It is very narrowly 
 separable from Melanoplus, and I do not see how it could be distin- 
 guished from it if we include in it, as Stal did, his Pezotettix plebejm 
 and rusticus. The combination of such peculiarities as the long- 
 antennae and strongly transverse subgenital plate of the male with 
 the long and parallel- sided prouotum of both sexes serves to distin- 
 guish it from Melanoplus, as here limited; while the strongly banded 
 sides of the body and the long and clepsydral cerci of the male in all 
 the species mark it as a peculiar type even if these markings and form 
 of genitalia do occur in certain species of the diversified genus 
 Melanoplus. 
 
 Three species are known and appear to be confined almost entirely to 
 our Atlantic and Gulf borders, though some of the species occur as far 
 inland as Indiana, Ohio, and Michigan. It is unknown west of the 
 Mississippi, except in Louisiana and Texas (though Professor Bruner 
 suspects its presence in Nebraska). They inhabit moist places. 
 
 The type is P. floriclana.

 in the female more or less infuscated ; above the antennae brownish 
 fuscous, more or less tinged with castaneous; behind the eyes a broad, 
 straight, horizontal, black band, edged more or less distinctly, both 
 above and below, with yellowish 5 antennae varying in length, being 
 relatively longer in southern than in northern examples, but generally 
 about two-thirds as long as the body in the male, yellow at base, 
 beyond testaceous, deepening into fuscous toward the tip, the apices 
 of the joints normally pallid. Upper surface of the pronotum of the 
 color of the top of the head, the upper half of the deflected lobes with 
 a very broad black band in continuation of that on the head, anteriorly 
 edged more or less distinctly, both above and below, with yellowish 
 and generally fading out before, or abruptly terminating at, the meta- 
 zona (in the earlier stages it continues uninterruptedly across the pro- 
 notum, and this persistence is occasionally shown in the adult, or is 
 indicated on the metazona by a brown band sometimes percurrent and 
 usually reduced in width); pleura with a horizontal stigmatal stripe 
 running backward from the hinder edge of the mesothoracic episterua 
 (sometimes confined to the mesothoracic epimera), and an oblique stripe 
 nearly following the division line between the metathoracic episterua 
 and epimera; when the lower stripe is complete it renders the meta- 
 thoracic episterna conspicuous, especially in the male, on account of 
 the cuneiform oblique yellow dash which lies between these two black 
 stripes. Hind margin of pronotum less distinctly angulate that is, 
 more uniformly rounded than in the other species, though the differ- 
 ence is but slight and sometimes disappears. Tegmina nearly uniform 
 brownish fuscous, often with a faint line of small fleckings down the 
 middle in the female. Legs of the color of the body, the middle and 
 hind femora generally more or less infuscated on their outer face, the 
 upper half of the geuicular lobes of the latter black ; hind tibiae glaucous 
 with black or blackish spines. Supraanal plate of male long triangular 
 with a broad mesial rounded ridge extending two- thirds its length, on 
 the summit of which, in the basal half of the plate, is a very narrow 
 deep sulcus which, after interruption, is repeated again in the apical 
 fourth; furcula consisting of a pair of moderately long, moderately 
 slender, cylindrical, slightly tapering, blunt, adjacent fingers (shorter 
 thtin usual in the specimen figured and drawn too stout), often diver- 
 gent; cerci lamellate, very long, strongly incurved, gradually narrow- 
 ing and then as gradually enlarging, so as to make the spatulate tip 
 nearly as broad as the base, the apical margin rounded and subeinar- 
 ginate. 
 
 The tegmina are ordinarily of about the length of the body, but, in 
 the South particularly, it often occurs with tegmina only reaching a 
 little beyond the middle of the abdomen. I have seen one such from 
 Massachusetts; and in a pair from Fort Worth, Texas, in the National 
 Museum the tegmina are scarcely longer than the pronotum and sub- 
 acuminate at tip. This form may receive the racial name texana.

 26. POECILOTETTIX, new genus. 
 (IIoiKiXoc, mottled; rs'rrzc, grasshopper.) 
 
 Head and body with the general aspect of Melunoplus. Head nearly 
 vertical, especially in the female, the eyes moderately large, moderately 
 prominent in the male, broad oval, not more than half as long again as 
 broad; antennae very little longer in both sexes than head and pro- 
 notum together. Pronotuin enlarging very slightly posteriorly, the 
 suture between prozona and metazona deeply impressed, with rounded 
 walls; the prozona scarcely or but little longer than the metazona, 
 coarsely and distantly punctate, the transverse sutures distinct and 
 rather heavy, transversely broadly convex with no lateral carinae; the

 metazona finely and closely punctate, slightly tumid in the female, 
 the angle of the lateral carinae well rounded, the posterior border 
 broadly angulato-convex, margined ; median carina obsolete or sub- 
 obsolete throughout. Prosternal spine slender, straight, acuminate; 
 meso- and metastethia together longer than broad; interval between 
 mesothoracic lobes distinctly, generally very much, longer than broad, 
 generally broader in the female than in the male, the metasternal lobes 
 subattingent or approximate, the portion of the metasternum behind 
 the lobes small, hardly more than twice as broad as long. Tegmiua 
 fully developed in all known species, remarkably uniform in width, 
 with the costa very slightly expanded near the base, and a strongly 
 and uniformly rounded apex. Hind femora moderately slender, with 
 immaculate inferior genicular lobes, the tibiae with eight to nine exter- 
 nal spines. Cerci of male extremely slender beyond the tapering lami- 
 nate base, thefurcula subobsolete; the lateral margins of the subgenital 
 plate ampliate at base and the apex provided with a distinct tubercle; 
 the pallium often has a pyramidal erection. 
 
 P. picticornis (Thomas) may be regarded as the type. 
 
 As far as known, this genus occurs only on the Pacific coast, near 
 our southern borders. It is remarkable for the tuberculate abdomen, 
 resembling Helper otettix, but apical instead of subapical, and for the 
 sometimes vivid and always exceptionally variegated colorings of its 
 different species.

 which oddly occurs at the apex of one and the base of the succeeding 
 joint, the incisures excepted; frontal costa slightly narrower than the 
 interspace between the eyes, uniform in width, deeply sulcate; eyes of 
 female anteriorly truncate, not more than half as long again as the 
 anterior infraocular portion of the genae. Pronotum most sparsely

 very feeble median cariua, continued on the prozoua as an impressed 
 line only ; hind margin obtusangulate, the angle rather broadly rounded. 
 Tegmina subhyaline on the apical half or more, both veins and cross- 
 veins very pale testaceous ; wings hyaline, nearly as long as the teg- 
 niina, of ample breadth, with pallid veins and cross veins. Hind tibiae 
 and tarsi luteous, the spines black tipped, varying from eight to nine 
 on the outer margin in both sexes. Supraanal plate of male triangular, 
 rather elongate, with rounded acute apex, the surface with two high 
 and sharp, subparallel, convergent and then divergent, longitudinal 
 ridges, fading apically, including between them a rather narrow and 
 very deep median sulcus extending the whole length of the plate, but 
 shallow apically; furcula consisting of two distinct, not large, adjacent, 
 rounded lobes, projecting by half their length; cerci moderately broad 
 and slightly inflated at the base, at once narrowing, wholly on the 
 upper side, beyond straight, compressed, equal, scarcely incurved, 
 about one- third the width of the base, the tip rotmdly pointed, reach- 
 ing as far as the tip of the supraaual plate; infracercal plates concealed 
 when the cerci are recumbent; lateral margins of the subgenital plate 
 sinuous, the apical tubercle a little elevated, broad, subtruncate, and 
 subbitid as viewed posteriorly, pilose.

 Two males, 2 females. Arizona, Dunn (L. Bruner; U.S.N.M. Kiley 
 collection). It was originally described by Thomas from Arizona. Pro- 
 fessor L. Bruuer writes me that he has received the same species from 
 Tepic, Jalisco, Mexico. 
 
 This insect may be instantly distinguished from every other in the 
 entire group of Melanopli by its peculiar blackish punctuation and the 
 annulate antennae. I had an opportunity of studying the type many 
 years ago, and part of the above description is taken from notes made 
 at the time.

 The bright coloring of this species recalls that of Dactylotum. Pro- 
 fessor Bruner informs me that this was the species referred to by 
 Townsend in Insect Life (VI, p. 30) as found at Hance's in the Grand 
 Canon of the Colorado, 3,000 to 5,000 feet below the rim. As all the

 retained the manuscript name of Brunei*, given by him to distinguish 
 it from the species of Dactylotum which have short wings. 
 
 3. POECILOTETTIX COCCINATUS, new species. 
 (Plate XXVI, fig. 3.) 
 
 Head brighter or duller yellow, more or less infumated, especially on 
 the lower half, but enlivened with crimson more or less distinctly (but 
 not so conspicuously) as in P. sanguineus and at somewhat similar 
 points, but especially on the fastigium, tlje sides of the labrum, the 
 clypeal suture, and the lateral carinae of the face, besides the medio- 
 dorsal stripe of the vertex; eyes of female as in P. sanguineus; antennae 
 apically acuminate, greenish plumbeous, the basal joints pale. Prono- 
 tuin most sparingly pilose, olivaceo-fuscous with shades varying from 
 olivaceous to fuscous, the latter more pronounced on the front part of 
 the metazona and the dorsum of the prozona, except an olivaceous, 
 continuous, mediodorsal stripe, more or less conspicuously marked with 
 a crimson thread; crimson also margins the lateral lobes of the meta- 
 zona and appears more or less distinctly on the upper half of the lateral 
 lobes of the prozona; the transverse sulci of the disk are only slightly 
 darker than the ground; metazona with crowded fine punctuation and 
 a slight median carina, the hind margin strongly convex, hardly angu- 
 late. Tegmina slender, far surpassing the abdomen, hyaline on more 
 than the apical half, the veins yellow; wings nearly as long as the teg- 
 mina, greenish hyaline, the veins of the upper half fuscous or greenish 
 fuscous, of the lower half and most of the cross veins glaucous. Fore 
 and middle femora luteous, clouded with fuscous; hind femora luteous, 
 the outer face infuscated and the upper area alternately pale fuscous 
 and luteous or carmine; hind tibiae and tarsi glaucous, the spines glau- 
 cous or pallid with black tips, seven to eight on the outer row in the 
 female, eight in the male. Abdomen light fuscous with dull luteous 
 areas, but no enlivennient with brighter colors; supraanal plate of 
 male triangular, elongate, the apex acute; surface with two parallel, 
 not distant, sharply elevated ridges which extend, diminishing pos- 
 teriorly, nearly or quite the length of the plate, including between them 
 a rather narrow and deep narrowing sulcus; furcula consisting of only 
 a slight thickening of the posterior edge of the last dorsal segment 
 above the two ridges of the supraanal plate; cerci not very broad at 
 extreme base, rapidly and regularly tapering in the basal third, the 
 remainder very slender, equal or barely expanded at the blunt 
 extremity; lateral margins of the subgenital plate straight on the 
 apical half, the apical tubercle not rising above their level but having 
 the same direction, conical, simple.

 27. OEDALEONOTUS, new genus. 
 (OtdaXeoS, swollen; r&jroS, back.) 
 
 Body stout, heavy and clumsy. Head large and full, the vertex well 
 arched, raised considerably above the level of the prothorax, the fas- 
 tigium broad, broadly and shallowly sulcate and considerably declivent, 
 the eyes separated rather widely; face nearly vertical: frontal eosta- 
 very broad, subequal, nearly plane, percurrent but sometimes obscure 
 basally; eyes rather large, not very prominent, broadly ovate, with a 
 slight production above anteriorly; antennae not slender, uniform,, 
 slightly longer (male) or slightly shorter (female) than head and pronotum 
 together. Pronotum short and stout, enlarging posteriorly only by the 
 slight flare of the metazoua, with vertical though slightly tumid lateral 
 lobes, more or less flaring on the metazona below, separated from the 
 dorsum by more or less pronounced, coarse, rounded rugae, generally 
 interrupted on the posterior portion of the prozona, the median carina 
 interrupted between the sulci; disk of prozona distinctly tutnid, but 
 little longer than the metazona, from which it is separated by a very 
 deep sulcus, its own posterior transverse sulci deeply impressed,, 
 approximate, and subparallel, the anterior submarginal sulcus also very 
 distinct, the margin being elevated to receive the head ; metazona plane, 
 punctato-rugulose, very obtusely augulate behind, the border inargi- 
 nate. Prosternal spine short, conical, blunt; ineso- and metastethia 
 together distinctly longer than broad in both sexes, the mesosternal 
 lobes a little longer than broad in both sexes, the metasternal lobes 
 subattingent in the male, slightly distant in the female, the space 
 behind the latter laterally elongate, extending forward to the coxae. 
 Tegmina fully developed or abbreviate, rarely shorter than the prono- 
 tum and then but slightly. Hind femora stout, heavy, and tumid, the 
 inferior genicular lobe pallid, immaculate. Abdomen of female with 
 abbreviated terminal segments (recalling Bradynotes) and partially 
 exserted ovipositor; of male not enlarged at the extremity and scarcely 
 elevated, terminating roundly and bluntly, the last ventral segment (in 
 advance of the subgenital plate) scarcely longer than the penultimate j 
 subgeiiital plate of male very brief and subequal, its lateral margins 
 distinctly ampliate at the base and entire apically, with no tubercle; 
 cerci tumid and enlarged at base, suddenly contracted, and terminating 
 in a slender posterior process. 
 
 This genus is quickly separated from those in its immediate vicinity 
 by the tumidity of the prozona, and the clumsy form, which give it a 
 very distinct appearance.

 I know of but a single species, which inhabits the Pacific coast from 
 Canada to Mexico, and which assumes three forms according to the 
 length of the organs of flight, that with the organs fully developed 
 being thus far known only from southern California, from the head of 
 the San Joaquiu Valley to San Diego. It is distinguished from the 
 others not only by the development of these organs, but by a slightly 
 slenderer body, the grossness of the others seeming to be correlated 
 with their incapacity of flight.

 median carina, which is marked with dark brown and is distinct 
 though slight on the inetazona, is obsolete on the prozona, represented 
 only by the dark line, sometimes faintly impressed ; lateral carinae very

 deeper color, unites thetwopercurrent sulci of the lateral lobes in the mid- 
 dle ; anterior margin of the prozona marked by a submarginal continuous 
 sulcus, distinct only on the lateral lobes 5 posterior border of the meta- 
 zona very broadly rounded or subaugulate. Prosternal spine straight, 
 rather slender, subconical, bluntly pointed. Teginina subovate, slightly 
 longer than the pronotum in the form jucundus, fully half as long as the 
 abdomen in the form enigma, fully as long as and generally much longer 
 than the abdomen in the form collaris, brownish fuscous, the longitudi- 
 nal veins mostly yellowish, and flecked, principally along the median 
 area but also without it, with longitudinal series of subquadrate, black- 
 ish fuscou* spots, the apex subacuminate when abbreviate, well rounded 
 when fully developed ; wings pellucid with fuscous veins. Pleura with 
 an oblique, bright yellow stripe, edged with black above the hind coxae. 
 Hind femora luteous, the outer and in part the upper face marked by 
 a large, apical, yellowish-brown spot, a very broad, an gulate, transverse 
 median band of the same color, and a similar basal band, sometimes 
 obsolete or obsolescent, on tne lower half; outer arc of upper genicular 
 lobes black; tibiae glaucous, yellow on the sides and at extreme base, 
 the apical half of the spines black; arolium either quadrate, rather 
 narrow, longer than the claws (male) or obpyriform, small, but little 
 more than half as long as the claws (female). Abdomen yellow, the 
 sides chafed by the femora dark fuscous ; supraanal plate of male rather 
 short triangular, the sides feebly sinuate, the apex acute, the surface 
 marked by a pair of deep and broad converging sulci, lying between

 Bruner reports the species also from Nevada and Arizona. 
 
 Palmer found this species on grassy slopes, beside brooks. 
 
 The form enigma appears to be the only one found in the northern 
 part of the range of the species north of central Caliibrnia, and the 
 form collaris is rarely met with anywhere. 
 
 The different forms have not been taken in coitu with each other, so 
 far as I know. The form jucundus besides having very short tegmina, 
 is noticeably smaller than the others. 
 
 I can scarcely think the form collaris to be the insect described by 
 Thomas as Caleoptenus [sic] flavolineatus, 1 as Bruner has supposed. 
 Thomas's description very poorly fits it; he makes no mention of the 
 tumid prozona, and he states, both here and subsequently, 2 that it 
 closely resembles Melanophis spretus, and that the posterior margin of 
 the subgenital plate of the male is notched, whereas its general appear- 
 ance is very different indeed from M. spretus; so much so that it can 
 hardly be believed that anyone would select it for comparison ; nor has 
 the apical margin of the subgenital plate the faintest sign of any 
 emargiuation. Thomas's specimen was derived from Crotch's collection 
 in the Museum of Comparative Zoology; Crotch collected Oedaleonotus 
 enigma collaris in central, not southern, California, whereas Thomas 
 gave his C. Jtavolineatus from southern California. Thomas's description 
 does not at all fit any species from southern California which has come 
 under my notice, and until such a form occurs his name should go for 
 nothing at least until the Acridian fauna of that region is fairly well 
 known.

 Body resembling Conalcaea iu general appearance, rather slender, 
 compressed cylindrical, feebly and sparsely pilose. Head moderately 
 large, not prominent, with feebly tumescent genae, the vertex well 
 arched, raised but little above the general level of the pronotum, the 
 fastigium rapidly descending, the face rounded and a little retreating ; 
 eyes separated widely, the fastigium depressed only between them and 
 very feebly, passing insensibly into the broad and equal frontal costa, 
 which is yet narrower than the interspace between the eyes, rounded, 
 fading below the ocellus; eyes large, moderately prominent, very broad 
 oval, the front border subtruncate, half as long again as the anterior 
 infraocular portion of the geuae ; antennae very slender, longer than the 
 head and pronotum together. Pronotum short, subequal, the metazona 
 flaring somewhat, transversely convex, the disk passing insensibly into 
 the subvertical lateral lobes, with no sign of lateral carinae, the median 
 carina slight and occurring only on the metazona; fore and hind mar- 
 gins both truncate, the latter feebly and broadly emarginate; prozona 
 coarsely and sparsely punctate, transverse, almost twice as long as the 
 finely and densely punctate metazona, the transverse sulci of the former 
 distinct, the postmedian more or less sinuate. Prosternal spine erect, 
 stout, subconical; meso- and metastethia together distinctly (male) 
 or slightly (female) longer than broad, the interval between the meso- 
 sternal lobes quadrate (male) or transverse and as broad as the lobes 
 (female); metasternal lobes rather (male) or distinctly (female) distant, 
 but in neither case more distant than the width of the frontal costa, the 
 portion of the thorax behind the metasternal lobes only a little more 
 than half as broad as the inetasternuin, but more than twice as broad 
 as long. Teginiua linear, lateral, shorter than the pronotum. Hind 
 femora not very long, but slender, the inferior geuicular lobe pallid and 
 immaculate, the hind tibiae with ten to twelve spines in the outer 
 series. Abdomen of male feebly clavate apically and somewhat up- 
 turned, the lateral margins of the subgenital plate strongly ampliate 
 at base, apically produced and acutangulate, but with no tubercle; 
 cerci substyliform ; abdomen of female tapering regularly to a pointed 
 tip, the ovipositor normally exserted.

 cially frontal costa punctate ; antennae ferruginous, apically infuscated 
 Prouotuin with the metazona ferrugiueo-testaceous, the prozona very 
 dark reddish brown, the upper two-thirds of the lateral lobes piceous 
 or plumbeo-piceous, sometimes merely dull piceous, with black sulci, 
 the lower portion of the lobes including the metazona luteous, fadiug 
 upward gradually on the metazona. Mesonotum, metanotum, and 
 abdomen dark reddish brown, with a sometimes obsolete, slender, flavo- 
 testaceous or ferrugineo-testaceous dorsal stripe edged with black, 
 which in some cases reappears on the prozona of the pronotum. Teg- 
 miua about as long as the prozona, 1 subequal, three or four times as 
 long as broad and well rounded at tip, fusco-testaceous, lighter along 
 the inner (upper) margin. Legs luteous, more or less heavily tinged 
 with ferruginous along the upper surface, the hind femora more than 
 the anterior pairs, the carinae being often more or less heavily marked 
 with black, the genicular arc black; hind tibiae very feebly incurved, 
 yellow luteous, the spines black-tipped. Supraanal plate of male trian- 
 gular with slightly rounded sides, the tip well rounded, with a deep 
 basal median sulcus, half as long as the plate and bounded by rather 
 high ridges, which after uniting in the middle again part slightly and 
 run parallel to the apex, leaving a slight sulcus between them; furcula 
 consisting of a pair of slightly separated minute triangular lobes; cerci 
 slender, slightly compressed, tapering gently on basal half, beyond 
 very slender, subcylindrical, scarcely tapering, acuminate, and curved 
 downward (the latter feature not shown in the figure); infracercal

 Bruner states that the Montana specimens were taken near Helena 
 " among the trailing junipers on north mountain slopes, at moderate 
 elevations." He also states that the colors of the living insect are 
 much more vivid than in cabinet specimens. " The yellowish hair- 
 lines and dorsal line of the abdomen are glossy white, while the front 
 and lower surface are of a bright lemon yellow; the brown is a bright 
 hazel." 
 
 In some specimens, especially of the female, the pronotum is crossed 
 by a narrow testaceous stripe which cuts the darker markings, running 
 
 Bruner states that the tegmina are sometimes absent, but I think only from indi- 
 Tiduals that have lost them by accident. I have seen only one in which they were 
 lost from both sides; several iu which they have been lost from one side.

 the female feebly and regularly enlarging posteriorly, in the male 
 equal on the prozona and faintly flaring on the metazona, the 
 disk in both sexes transversely convex and passing quite insensibly 
 into the vertical lateral lobes; the ground color of the prouotum

 irregularly, which however forms a broad dorsal band (divided 
 in the female by a mediodorsal flavous stripe) crossing the prozona 
 only, and very broad piceous (male) or brownish fuscous (female) 
 postocular bands crossing the whole pronotum, broken to some extent,

 ten, rarely nine or eleven, in number in the outer series. Abdomen with 
 meso- and metathorax dull flavo-testaceous, heavily overlaid with black 
 in more or less broken continuation of the pronotal stripes and bands, the 
 slender mediodorsal flavous stripe of the prozoiia also repeated on the

 By the kindness of Doctor Aurivillius of Stockholm, I am able to 
 illustrate the male abdomen of StaPs type (fig. 9), which I should have 
 been unable to identify with certainty from the rather meager descrip- 
 tion. I do not find the apex of the hind tibiae black, as Stal states 
 them to be.

 (ATtrrfv, unfledged; Ttrfddoo, to leap.) 
 
 Aptenopedes SCUDDER, Proc. Bost. Soc. Nat. Hist., XIX (1877), pp. 83-84. 
 
 Body compressed, especially in the female, where it is also feebly 
 fusiform, feebly pilose. Head projecting, front strongly oblique, whole 
 summit of head horizontal, scarcely convex, triangular; eyes nearly 
 meeting above, especially in the male, where they are separated by a 
 space not wider than the narrowest part of the frontal costa, the fastig- 
 jum in front of them laterally expanded and slightly tumid; front sub- 
 appressed, particularly in the female, almost straight; eyes long oval, 
 moderately prominent, in the female depressed and tapering above; 
 antennae moderately slender, linear, subdepressed, about as long as 
 (female) or slightly longer than (male) the head and prouotuin together; 
 palpi rather small, the last joint nearly cylindrical, not in the least 
 expanded. Pronotum regularly expanding posteriorly in the female, 
 only expanding at the very tip and then but slightly in the male; front 
 margin slightly convex, hind margin slightly and angularly excised; 
 surface uniformly rugulose, tectiform, especially in the female, the 
 median carina distinct but not prominent, the lateral carinae wholly

 wanting; metazoua less than half as long a& the prozona, the latter 
 divided a little behind the middle by a scarcely perceptible sinuate 
 sulcus; lateral lobes nearly twice as long as broad, narrowing down- 
 ward, the inferior margin very broadly angulate, the posterior margin 
 roundly excised. Prosternal spine blunt, conico-cylindrical ; inner mar- 
 gin of mesosternal lobes broadly convex, the lobes subapproximate 
 (male) or distant from each other by half their width (female); meta- 
 sternal lobes subcontiguous in both sexes. Tegmiua linear, about as 
 long as the pronotum, or absent. Hind femora extending nearly to 
 (female) or a little beyond (male) the tip of the abdomen, the superior 
 margin unarmed, the hind tibiae with their outer edges smooth, the 
 spines similar in length on the two sides, those of the outer series nine 
 to ten in number; first and third tarsal joints equal, the second less than 
 half as long as either. Abdomen indistinctly carinate throughout, the 
 extremity scarcely enlarged in the male; subgenital plate ampliate at 
 base, short, not projecting far beyond the tip of the small supraanal 
 plate, and in particular so little elevated posteriorly as to expose the 
 recumbent pallium more or less to a posterior view; furcula feeble; 
 cerci styliform; infracercal plates highly developed. 
 
 In general appearance the species of this genus most nearly resemble 
 those of Gymnoscirtetes Bruner, Paradichroplus Brunner, and Scopas 
 Oiglio Tos. The distinctions of the genus from the first, besides its 
 ampliate subgenital plate, are pointed out under that genus. From 
 Paradichroplus it differs in its more compressed body, the more taper- 
 ing vertex, the slenderer tegmina (when they are present), the lack of 
 any enlargement of the tip of the male abdomen, with the shorter sub- 
 genital plate, the ampliate basal margin of the same, the posteriorly 
 exposed pallium, and the wholly simple cerci. From Scopas, which I 
 have not seen, it appears to differ in its more prominent prosternal 
 spine, its narrower labruin, more declivent face, less cylindrical pro- 
 notum, with its excised posterior margin, besides its simple cerci. Its 
 subconical head, especially in the female, gives it a peculiar aspect. 
 
 A. sphenarioides Scudder, is the type. 
 
 Three species occur in the Southern States along the borders of the 
 Gulf of Mexico, and may be separated as follows:

 2. UNDETERMINED FORMS. 
 
 1. Poepedetes corallinus Saussure, Rev. Mag. Zool., 1861, p. 158. Mexico temperata. It is doubtful 
 if this Mexican species, unknown to me, belongs in the Melanopli ; it seems to be more nearly allied 
 to Dactylotum. 
 
 2. Pezotettix fauriei Bolivar, Anal. Soc. Esp. Hist. Nat., XIX (1890), pp. 322-323. This species from 
 Yesso, Japan, seems to be a Podisma, but it is described from the female alone, so that I can not 
 place it more closely. 
 
 3. Caleoptenus (sic I) Jlavolineatus Thomas, Bull. U. S. Geol. Surv. Terr., I, Istseries, No. 2 (1874), p. 68. 
 I am unable to determine this southern California species, and am tolerably confident I have not seen 
 it; for in this case there is apparently sufficient in the description to fix the species when specimens 
 are obtained. It has been thought by some to be Oedaleonotus enigma collaris, but that is scarcely 
 possible. 
 
 4. Pezotettix mexicana Saussure, Rev. Mag. Zool., 1861, p. 160. Mexico temperata. From the descrip- 
 tion it is impossible to determine which of the many Mexican species this may be, but I suspect it 
 may prove to be Melanoplus atlanis. 
 
 5. Pezotettix mikado Bolivar, Ann. Soc. Esp. Hist. Nat., XIX (1890), p. 323. Yesso, Japan. Like the 
 other species of Bolivar, No. 2, this is described from the female only, and I can not place it. It is pre- 
 sumably a Podisma. 
 
 6. Caloptenus repletus Walker, Cat. Derm. Salt. Brit. Mus., IV (1870). pp. 678-679. I had thought this 
 species to be probably Melanoplus bilituratus, but there was little in Walker's description whereon to 
 base ;m opinion. Mr. Samuel Henshaw, however, kindly compared bilituratut with the specimens 
 placed under repletus in the British Museum and found them distinct. Walker credited it to "U. 
 States " and " Vancouver's Island," one specimen each, but Mr. Henshaw found no specimens from 
 Vancouver, but two males and a female from " North America," one specimen being further labeled 
 "Illinois." The two males were different species, one being Melanoplus femoratus, the other (Illinois) 
 distinct, but allied to it by the cerci, though with short tegmina (probably Melanoplus viola). It was 
 further doubtful whether the female belonged with either of the males. Certainly, then, we shall be 
 obliged to consign Walker's species to merited oblivion. Probably no one of these specimens is one 
 of the original types. 
 
 7. Calliptamug sanguineipes Serville, Rev. Meth. Orth. (1831), pp. 93-94 [Aerydium sanguineipet 
 Olivier, Encycl. Meth., VI (179J), p. 231]. Surinam. It is very doubtful if this belongs in the Melan- 
 opli. If De Geer's Acridium aeneo-oculatum is the same l his figure would lead us to presume it did 
 not. I have not seen the species.

 8. Caloptenus scriptus Walker, Cat. Derm. Salt. Brit. Mus., IV (1870), pp. 680-681. The only form to 
 which. I was inclined to refer this was that described here as ^lelanoplus bilitiiratus, but from Mr. Hen- 
 shaw's examination of the types (see that species, p. 176) it can not be that, and I therefore find it at 
 present indeterminable. I have specimens from Vancouver, the origin of Walker's species, which may 
 possibly be referred to scriptus, since they differ from Melanoplus bilituratus in the points specified by 
 Mr. Henshaw, but as I possess only females I do not feel satisfied of their specific validity. 
 
 9. Caloptenus selectus Walker, Cat. Derm. Salt. Brit. Mus., IV (1870), p. 682. Walker's types (from 
 Oajaca, Mexico) were examined at my request by Mr. Henshaw to see whether they belong in the 
 group Melanopli at all, and he states that they do. It is quite impossible by Walker's description 
 even to guess to what genus it belongs, much less to determine the species without a direct compari- 
 son with the types. I know of no species with a broad, interrupted, piceous stripe along the costa of 
 the tegmina. 
 
 10. Pedies virescens Saussure, Rev. Mag. Zool., 1861, pp. 157-158. Mexico. I have not been able to 
 determine this species among my material, and question very much whether it belongs in the Melan- 
 opli. I am more inclined to think it allied to Dactylotum. 
 
 11. Podisma viridis Blanchard, Gay, Faun. Chil., Zool., VI (1851), pp. 75, 76. Chile. This is not one 
 of the Melanopli, but belongs to Antandrus Stal. 
 
 Several other species have not been definitely determined, but have been placed in the synonymy of 
 the described species with a mark of doubt. Such are Caloptenus arcticus Walker, Locusta leitcostoma 
 Kirby, Pezotettix longicornis Saussure, P. sumichrasti Saussure, and P. zimmermanni Saussure, for 
 which see the last preceding list (Appendix 1).

HO. 1124. REVISION OF THE MELANOPLI SC UDDER. 407 
 
 EXPLANATION OF PLATES. 
 
 With the exception of a few figures specially noted below, all the drawings for 
 these plates were made by Mr. J. Henry Blake, of Cambridge, Massachusetts, and 
 the expense met by a special grant for the purpose from the ELIZABETH THOMPSON 
 SCIENCE FUND, which is here gratefully acknowledged. 
 
 Unless otherwise stated (under the names of individuals or institutions placed in 
 parentheses), all the drawings of American species were made from specimens in my 
 own collection. Plate I illustrates the venation of the tegmina in a few species, and 
 the figures are here magnified five diameters. The remaining plates show the abdom- 
 inal appendages of the males of all but two or three of the species, and these are 
 
 magnified four diameters.
