 THE NORTH AMERICAN CEUTHOPHILI^ 
 BY SAMUEL H. SCUDDER. 
 
 Presented May 9, 1894 
 
 THE Ceuthophili are wingless Locustarians in which the tarsi are 
 distinctly compressed rather than depressed, with no pulvilli,* the hind 
 tibiae furnished on the outer margins above with spines of two distinct 
 grades,f the fore femora without foramina or genicular spines, the 
 hind femora with the angle of their insertion on the inner and not on 
 the outer side beneath, and the antennae strongly approximated at 
 base. They are all apterous. 
 
 With the exception of the genus Troglophilus Krauss, with two 
 species from European caverns, and the genus Talitropis Bol., with a 
 single species from New Zealand, placed respectively at one and the 
 other end of the series, they are known only from America ; and with 
 the further exception of Heteromallus Brunner, with two species 
 from Chili, they are all peculiar to the United States and Northern 
 Mexico. Here they include six genera and sixty-seven species, the 
 genus Ceuthophilus alone containing above fifty species. The larger 
 proportion of them, if not all (excepting Udeopsylla nigrd), frequent 
 dark places, such as burrows, pits, caverns, wells, hollow trees, and 
 especially the crevices beneath fallen logs. 
 
 They were first made known in this country by the descriptions of 
 Haldeman, Girard, and Harris, and before their time only a single 
 species from this country had been described, by Burmeister. Not a 
 species of the group, even the European, was known to Serville. My 
 first systematic paper, in 1861, was a study of " Rhaphidophora " 
 (Proc. Bost. Soc. Nat. Hist., VIII.) where seven of our species were 
 
 * Brunner states that Gammarotettix has a single pulvillus on the first tarsal 
 joint; but although the treading surface of this joint (as of the succeeding) is 
 broad, I can find no indication of a true pulvillus. 
 
 t This feature is obscure in Gammarotettix, where there are alternating 
 longer and shorter spines of such slight inequality as easily to be overlooked, 
 and which in the Table of Genera given below is ignored.

 described or catalogued ; but their diversity was hardly fully recog- 
 nized when in the following year I published my Materials for a 
 Monograph of the li'orth American Orthoptera (Bost. Journ. Nat. 
 Hist., VII.), where eighteen species and five genera were characterized 
 or indicated ; since then a few more species have been described, by 
 Thomas, Brunner, Bruner, Packard, Walker, Blatchley, and myself, 
 until now the number of nominal species is twenty-eight, which must, 
 however, be reduced by synonymy and by reference to other genera to 
 twenty. 
 
 In 1888, Brunner, in his Monographie der Stenopelmatiden und 
 Gyllacriden (Verb. Zool.-bot. Gesellsch. Wien), subjected all the spe- 
 cies known to him to systematic treatment ; but as the larger part of 
 our species and some of our genera were unknown to him, and the 
 number of separately described species has multiplied so greatly while 
 still not including, at least in Ceuthophilus, the half of our species, it 
 has seemed desirable to undertake a revision of the group, so far as 
 our native species are concerned, and in the genus Ceuthophilus to 
 redescribe all the older forms, as well as to publish the novelties. 
 Accordingly in the present paper thirty-eight additional species of 
 the group are characterized, together with a new genus, while I shall 
 further show the validity of Daihinia of Haldeman, which has been 
 called in question by Brunner, and shall point out first that one of the 
 genera thought to belong here should be separated as a member of a 
 distinct group. The total number of genera from North America is 
 therefore six, and of the species sixty-seven, while a number of other 
 species are known to me imperfectly by a single sex or poor examples.

 in his Monograph of the Stenopelmatidae, Brunner von Wattenwyl, 
 from the insufficient data given in my two statements regarding the 
 structure of this creature, incorrectly surmised that this genus should 
 be placed in the Ceuthophili, and was perhaps congeneric with Hetero- 
 mallus, a Chilian genus. Since, however, the hind tibiae are supplied 
 above with spines of one grade only, it is plainly more nearly related 
 to the Dolichopodae, from which it may be distinguished by the simi- 
 larly spined margins of the under surface. It seems to form a group 
 apart, between the Dolichopodae and Ceuthophili, and of equivalent 
 value. It appears to come nearer Hadenoecus and Dolichopoda than 
 to any other described genera.

 In addition to the characters mentioned above and those given in 
 previous descriptions, I may add that all the legs are tetraquetrous, 
 with all the margins spined, the spines similar in character and uni- 
 formly crowded, excepting on the lower margins of the fore femora, 
 the inner carina of which is sparsely spiued, the outer carina unarmed; 
 also the lower margins of the middle femora, both carinae of which are 
 sparsely spined on the apical half ; and the hind femora, the four 
 carinae of which, even on the swollen portion, are armed excepting at 
 the extreme base, though both the inferior carinae are rather sparsely 
 spined. There are no spines on the genicular lobes of the femora, 
 excepting a very slight one on the posterior side of the middle femora. 
 There are but two pair of calcaria on the hind tibias, the upper the 
 longer and less than half as long as the first tarsal joint. The hind 
 tarsi are very strongly compressed, carinate beneath without pulvilli, 
 about two fifths as long as the hind tibiae, the first joint nearly as long 
 as the remaining joints together, the second and fourth joints of the 
 same length and either of them three times as long as the third. 
 Finally, the subgenital lamina of the male is ample, the hind margin 
 entire, with minute styles, consisting of a single bluntly conical joint ; 
 and the ovipositor is slender, gently arcuate, tapering and acuminate, 
 unarmed at tip.

 This is one of the dominant American genera of Locustariae, con- 
 fined to North America and almost entirely to the United States, 
 embracing a large number of species in every section of the country, 
 of which fifty-five are here characterized. Several others are known 
 to me by single specimens or mutilated examples. The following 
 table is based principally upon the males. It has been impossible to 
 construct it so as to bring together the allied species, whose relation- 
 ship is better shown by the order in which they are described, though 
 even here the arrangement is far from satisfactory, nearly allied 
 species being sometimes separated at considerable distances in order to 
 bring them in closer relation with other allies. Although I have had 
 six hundred and fifty examples to study at this time, besides others in 
 alcohol, the material is still insufficient to make a satisfactory disposi- 
 tion of our species, and I am confident that very many more yet 
 remain to be discovered.

 Blackish fuscous with a slight olivaceous tinge, marked with yel- 
 lowish luteous ; there is an interrupted dorsal stripe of the lighter 
 color especially interrupted on the anterior half of the pronotum ; this 
 is heavily margined by subconfluent dark blotches or spots, and the 
 dark color prevails over the rest of the thorax, with oblique patches of 
 the lighter tints on the meso- and metanotutn, irregular vermiculate 
 blotches of greater or less extent on the pronotum and the lower 
 edges of the descending lobes of the thorax margined not very nar- 
 rowly with luteous ; the sides of the abdomen are prevailingly luteous, 
 but the anterior outer margins are mostly fuscous ; the hind femora 
 have the usual scalariform markings very pronounced, while the other 
 legs are prevailingly luteous and much streaked with fuliginous, 
 excepting the tarsi ; the longer spines are bright luteous, but black 
 tipped. The antennae are two or three times as long as the body}

 there are also two large subdorsal anterior blackish fuscous spots 
 on the meso- and metanotum, and the pronotum has a large T-shaped 
 blackish median spot heavily mapped out with a basal expansion and 
 which is cut by a mediodorsal luteous line, bordered on either side

 Ground color of body varying from luteous to dark castaneous, very 
 heavily marked with blackish fuscous, so that the latter is often or 
 perhaps generally the prevailing tint; the darker colors prevail always 
 on the hinder half of all the segments but the pronotum and some- 
 times, especially in young specimens, to such an extent that all parts 
 behind the pronotum are blackish fuscous, dotted with luteous ; in the 
 lightest colored specimens, the dark coloring prevails on the pronotum 
 along the anterior and especially the posterior margins, and is generally 
 present in a subdorsal posterior tongue emitted on either side from the 
 anterior margin ; the anterior edge of the dark posterior markings of 
 each segment, especially in the front portion of the body, is exceed- 
 ingly irregular and broken, and the lightest parts are more or less and 
 irregularly clouded with fuscous ; the femora are usually of the pre- 
 vailing tint of the body, but, even when the body is dark, are some- 
 times luteous throughout as the tibia? and tarsi always are, except for 
 occasional infuscation of the former at base ; the outer sides of the 
 hind femora have the characteristic markings of the genus more or less 
 distinct. Antennse moderately coarse at base, tapering with great 
 regularity, 3-4 times the length of the body. Legs very long and 
 slender. Fore femora no stouter than the middle femora, more than 
 half as long again as the pronotum, especially in the , distinctly less 
 than half as long as the fore femora, the inner carina usually with 2-3

 Middle femora with 3-4 spines on either carina, the hind carina 
 with a not very long genicular spine. Hind femora as long as or 
 longer than the body, considerably more than twice the length of the 
 fore femora, very stout at base, but gradually diminishing in stout- 
 ness so that the distal third is slender and subequal and the whole 
 less than three and a half times longer than broad, the surface mostly 
 glabrous, but on the darker portions above beset not very sparsely 
 with feeble raised points, the outer carina with about thirteen distant un- 
 equal rather coarse spines, the longest shorter than the tibial spurs ( $ ) 
 or almost unarmed (9), the inner carina much less elevated than 
 the outer, with equal abortive denticulations numerous in the , in- 
 frequent and equidistant in the 9 , the intervening sulcus moderately 
 broad. Hind tibiae rather slender, straight or in old male specimens 
 gently subarcuate or slightly waved in the proximal third, nearly a 
 sixth longer than the femora, armed beneath usually with two aligned 
 preapical spines besides the apical pair ; spurs subopposite, the basal 
 pair near end of proximal fourth of tibia, less than half as long 
 again as the tibial depth, set at an angle of about 40 with the tibia 
 and usually divaricating about 60, but sometimes to as much as 
 twice that, incurved especially at tip; inner middle calcaria much 
 longer than the outer, more than twice as long as the other calcaria, 
 about twice the length of the spurs, but much shorter than the first 
 tarsal joint. Hind tarsi much less than half as long as the tibia, the 
 first not so long as the rest together, the second nearly three times as 
 long as the third and with tt fully as long as the fourth. Cerci stout at 
 base, tapering throughout, nearly a third as long as the hind femora. 
 Ovipositor with the basal third rather stout, beyond equal and rather 
 slender, nearly three fourths the length of the hind femora, the arma- 
 ture of inner valves acicular, arcuate, elongate.

 Body dark luteo-castaneous very heavily marked with blackish or 
 blackish fuscous, which is heaviest at the posterior margins of all the 
 segments, along the front margin of the pronotum, and in a stripe 
 bordering the broad mediodorsal rufo-luteous stripe of the pronotum ; 
 the anterior lower angle of the pronotum, and to some extent that

 This species is not far removed from G. gracilipes in structural 
 details, though with much duller and less diversified markings. 
 
 7. CEUTHOPHLLUS SECRETUS, sp. nov. 
 
 In markings this species agrees altogether with O. palmeri except 
 that the luteous colors are clearer and that the abdomen is more com- 
 pletely fuscous, the luteous being almost entirely confined to a narrow 
 stripe across the anterior margin, not seen when the segments are 
 contracted. The antennae are fully three times the length of the 
 body, slender and gradually tapering, the legs long and slender. 
 Fore femora scarcely stouter than middle femora, considerably more 
 than half as long again as the pronotum and about half as long as the 
 hind femora, the inner carina with 1-3 small spines. Middle femora 
 with 2-4 spines of varying length on the front carina, and on the hind 
 carina occasionally a single small spine besides the long genicular spine. 
 Hind femora nearly as long as the body, about twice the length of the 
 fore femora, tapering with no abruptness, nearly four times as long as 
 broad, the apical fourth subequal, with scattered but nowhere numerous 
 minute raised points on the upper apical half, the outer carina with 
 small but rather coarse unequal spines, mostly next the narrower por-

 both sexes, slender, about an eighth longer than the femora, armed 
 beneath with two subapical spines besides the apical pair; spurs 
 scarcely subopposite, the basal at the end of the proximal third of the 
 tibia, almost or quite twice as long as the tibial depth, set at an angle 
 ordinarily of 30-40, but sometimes of more nearly 80 with the tibia, 
 divaricating 100160, their tips incurved; inner middle calcaria con- 
 siderably longer than the outer, nearly twice as long as the others or 
 as the spurs, but much shorter than the first tarsal joint. Hind tarsi 
 almost half as long as the tibiae, the first joint as long as the rest 
 together, the second three times as long as the third and with it longer 
 than the fourth. Cerci slender, tapering, half as long again as the 
 femoral breadth. Ovipositor fully three fourths as long as the hind 
 femora, gently and uniformly arcuate throughout, of equal width 
 throughout, the tip not sharply acuminate, the inner valves with a 
 feebly crenulate armature.

 Body blackish fuscous, glabrous, liberally sprinkled with luteo- 
 testaceous giving it a speckled appearance in best marked specimens ; 
 some of these spots or dots are clustered in a more or less conspicuous 
 mediodorsal stripe, while others margin subequidistantly the posterior 
 border of all the abdominal segments or are submarginal ; on the pro- 
 notuna and to a less degree on the meso- and metanotum they are liable 
 to coalesce and form vague and irregular patches and blotches ; the 
 fore and middle legs are luteous, more or less infuscated especially at 
 the distal ends of the femora ; hind femora brownish fuscous, often 
 with an olivaceous tint, the scalariform markings nearly obsolete. 
 Antennae very slender, about twice the length of the body, the legs 
 rather short. Fore femora no stouter than the middle femora, about 
 a third ( (?) or a fourth (9 ) longer than the pronotum, and much less 
 than half as long as the hind femora, the inner carina with a subapical 
 spine sometimes accompanied by a few others near it. Middle femora 
 with a subapical spine sometimes accompanied by one or two others 
 on the front carina, and on the hind carina a not very long genicular 
 spine sometimes accompanied by two others. Hind femora rather 
 slender, tapering almost regularly, about three and a half times as long 
 as broad, considerably more than twice as long as the fore femora, 
 with no raised points upon the surface, the outer carina very finely 
 denticulate ( $ ) or wholly or almost wholly unarmed ( 9 ) > the inner 
 carina feebly and very finely serratulate, the intervening sulcus narrow. 
 Hind tibiae straight in both sexes, a little longer than the femora, 
 slender, armed beneath with a single subapical spine besides the apical 
 pair ; spurs opposite or subopposite, the basal at the end of the proxi- 
 mal fourth of the tibia, no longer than the tibial depth, set at an angle 
 of about 45 with the tibia and divaricating about 60 ; inner middle 
 calcaria considerably longer than the outer, more than twice as long 
 as the others or as the spurs, but shorter than the first tarsal joint. 
 Hind tarsi a little less than half as long as the tibia, the first joint 
 scarcely as long as the rest together, the second much more than 
 twice as long as the third and with it longer than the fourth. Cerci 
 slight, tapering regularly, about three fourths as long as the femoral 
 breadth. Ovipositor straight, tapering on the proximal, slender and

 Dull fuliginous brown, but glabrous, marked with very dull and pale 
 luteous dots, occasionally somewhat confluent ; there is sometimes, but 
 rarely, a mediodorsal luteous stripe on the pronotum ; the dots are 
 generally a little elongate and margin the segments posteriorly, often 
 turned obliquely inward and when accompanied by other dots in 
 advance these arranged to give an added obliquity to their general 
 course ; the pronotura is more or less marmorate with dull luteous ; 
 the legs have the general tone of the body and the hind femora the 
 usual markings of the genus, the darker colors generally the more 
 extensive, but the pattern obscured apically so that the distal extremity 
 of the femora, including more than the geniculation, is more or less 
 deeply infuscated. The antennas are stout at base but immediately 
 become slender and are at least twice as long as the body. The legs 
 are short and rather slender. Fore femora no stouter than the middle 
 femora, a third longer than the pronotum and about half as long as 
 the hind femora, the inner carina with a subapical spine. Middle 
 femora with a subapical spine on the front carina and on the hind 
 carina 1-2 spines, sometimes wanting in the 9 , besides a fairly long 
 genicular spine. Hind femora moderately stout and plump, regularly 
 tapering, about three and a half times longer than broad, the distal 
 fifth equal, the surface with no raised points, both carinas sparsely and 
 finely serrate in the , almost unarmed in the 9> the intervening 
 sulcus of moderate breadth and V- sna P e d- Hind tibia? considerably 
 longer than the femora, unusually slender, straight in both sexes, 
 armed beneath with two preapical spines besides the apical pair ;

 40-45 with the tibia and divaricating about 135, their tips incurved;

 tarsal joint. Hind tarsi about two fifths the length of the tibia, the 
 first joint shorter than the others together, the second twice as long 
 as the third and with it as long as the fourth. Cerci rather slender, 
 regularly tapering, slightly longer than the femoral breadth. Oviposi- 
 tor gently tapering on proximal, equal on distal half, rather slender, 
 very slightly arcuate, two thirds the length of the hind femora, the 
 tip acute but not produced, the armature of the inner valves a dull 
 and nearly obsolete serration.

 Body glabrous, blackish above and on upper part of sides, with a very 
 broad dark rufous mediodorsal stripe, narrowing on the abdomen and 
 disappearing in the middle of the same, the black portions sprinkled, 
 especially on the abdomen where it covers all the sides, with rufo-lute-

 Burmeister's Phal. lapidicola came from Virginia and South Caro- 
 lina. The present species is the only one known to me from the 
 Southern Atlantic States which completely or approximately agrees 
 with his description, the species formerly referred by me and others 
 to this being a Northern form to which the description poorly fits, 
 and that described by Brunner under this name is a very different 
 insect.

 17. CEDTHOPHILUS ARIZONENSIS, sp. nov. 
 
 Pallid luteous, so heavily infuscated that behind the pronotum there 
 is only left a single series of luteous spots on each side, which on the 
 meso- and metanotum are transverse oval and rather large, and on 
 the abdomen are transverse anterior stripes, sometimes confluent with 
 those of the opposite side ; the pronotum is mostly fuscous, deepest 
 around the margin, more or less dotted and vermiculate with luteous 
 elsewhere, there being commonly a transverse row of dots bordering 
 the anterior fuscous margin, and the disk on either side more or less 
 heavily blotched with the same ; the legs are fuscous, varying in depth 
 in different individuals, the hind femora generally with sufficiently 
 conspicuous scalariform markings. The antennae are very slender and 
 fully three times as long as the body, and the legs are slender but not 
 very long. Fore femora slightly stouter than the middle femora, a 
 third longer than the pronotum and half as long as the hind femora, 
 the inner carina with one or two spines. Middle femora with 1-3 
 spines on the front carina, and the hind carina generally unarmed 
 except for a slight genicular spine, but sometimes with as many as 
 three other minute spines. Hind femora nearly as long as the body, 
 twice the length of the fore femora, moderately slender, being a little 
 less than three and a half times longer than broad, gradually diminish- 
 ing in size and yet with the distal fourth subequal, the surface with no 
 raised points, the outer carina with only a few raised points, mostly on 
 the distal half, the inner carina with most minute but sharp distant 
 spinules, the intervening sulcus narrow. Hind tibia? scarcely longer 
 than the femora, straight in both sexes, very slender, armed beneath 
 with a single preapical spine besides the apical pair; spurs nearly 
 opposite, the basal beyond the end of the proximal third of the tibia, 
 about as long as the tibial depth, set at an angle of from 35-40 with 
 the tibia and generally divaricating about 70-80 (one example about 
 100), their tips incurved ; inner middle calcaria a little longer than 
 the outer, fully twice as long as the others or as the spurs, but much 
 shorter than the first tarsal joint. Hind tarsi less than half as long 
 as the tibiae, the first joint fully as long as the rest combined, the 
 second twice as long as the third and with it as long as the fourth. 
 Cerci stout on the proximal, slender on the distal half, nearly as long 
 as the femoral breadth. Ovipositor four fifths the length of the hind 
 femora, slender, nearly straight, tapering slightly, the tip finely pointed 
 at an angle of about 30 and barely upturned, the armature of the 
 inner valves aculeate, only the terminal arcuate.

 Smoky luteo-testaceous with a slight olivaceous tinge, glabrous, 
 marked more or less deeply with fuscous along the posterior margins of 
 the segments and generally along the anterior margin of the pronotum ; 
 in this posterior infuscation are indistinct dots of luteous in a trans- 
 verse series ; generally there is also a mediodorsal luteous line over 
 all the segments but deepest and broadest on the pronotum, which is 
 also laterally irregularly streaked, clouded, or blotched with luteous ; 
 beyond the lighter more luteous bases of the femora, the legs are of 
 the body color, but the hind femora are considerably inf'uscated in a 
 scalariform pattern, apically confluent. The antennae are slender and

 19. CEDTHOPHILUS HEROS, sp. nov. 
 
 Body castaneous, so heavily marked with black or blackish fuscous 
 as to appear rather as black marked with castaneous ; the latter 
 appears on the pronotum only in a very broad mediodorsal stripe of 
 unequal width, an impure blotch in the middle of the sides usually 
 connected with the former, and an inferior edging sometimes expand- 
 ing anteriorly ; in younger specimens, however, it extends over nearly 
 all the surface ; on the meso- and metanotum it margins the segments 
 anteriorly except below, separated from the black irregularly, and 
 extends mediodorsally across the segments ; on the abdomen it appears 
 as small spots dotting the surface and merging along the anterior mar- 
 gins ; the antennae are pale fuscous obscurely and distantly annulated 
 with luteous; the legs are castaneous, more or less infuscated, the

 hind femora externally marked heavily with fuscous in a scalariform 
 pattern, with a broad obscure castaneous annulation well before the 
 genicular lobes. The antennae are slender and exceedingly long, 
 about four times as long as the body, and the legs are very long though 
 only moderately slender. Fore femora no stouter than the middle 
 femora, a little less than half as long as the hind femora, and rather 
 more (<) or rather less (9) than three fourths as long again as the 
 pronotum, the inner carina with 2-3 spines. Middle femora with 
 similar spines on the front carina and on the hind carina a couple of 
 similar spines besides a not very long genicular spine. Hind femora 
 fully as long as the body, a little more than twice as long as the fore 
 femora, the basal portion stout and swollen but delicately tapering so 
 that nearly or in the female quite the apical third is subequal, and the 
 whole is four times as long as broad, the upper edge of the inner sur- 
 face with 4-5 distant raised points, the outer carina with about ten 
 sub-equal spines, the longest much shorter than the tibial spurs ((?), 
 or with about six slight and distant recumbent spines (9)> the inner 
 carina rather bluntly denticulate, distantly in the outer half ((J) or 
 like the outer carina but more closely denticulate (9) the intervening 
 sulcus narrow. Hind tibiae barely arcuate at base (<J) or straight (9), 
 a very little longer than the femora, armed beneath with 1-2 sub- 
 apical spines besides the apical pair ; spurs subopposite, the basal at 
 the end of the proximal third of the tibia, a little longer than the tibial 
 depth, set at an angle of about 60 with the tibia and divaricating 
 about 130 (<J) or 150-170 (9), incurved at tip; inner middle cal- 
 caria a little longer than the outer, twice as long as the others or as 
 the spurs, and as long as the first tarsal joint. Hind tarsi two fifths 
 as long as the tibia?, the first joint much shorter than the rest together, 
 the second nearly three times as long as the third and with it fully as 
 long as the fourth. Cerci slender, nearly half as long again as the 
 femoral breadth. Ovipositor three fifths as long as the hind femora, 
 straight, tapering and not very stout in the basal, slender and equal in 
 the apical half, the apex obliquely truncate, upturned, and acuminate 
 but not much produced, the teeth of the inner valves rather short

 Dull luteo- or rufo-testaceous, very heavily flecked with dark fuscous 
 so as to produce a tolerably uniform mottled appearance, ordinarily a 
 little more open than elsewhere in a narrow mediodorsal streak on the 
 pronotum, and in the tolerably clear luteous or pallid luteous of the 
 inferior margin of the descending thoracic lobes ; the flecking is made 
 up of small more or less confluent dots, which assume a certain longi- 
 tudinal regularity on the abdomen only ; legs varying from luteous to 
 testaceous, more or less infuscated, especially on the apical portions of 
 the femora and in the distinct and heavy scalariform markings of the 
 hind femora. The antennae are moderately stout in the basal, but in 
 the apical half very slender, apparently only a little more than twice the 
 length of the body, the legs moderately long. Fore femora no stouter

 but not so pronounced as in C. uhleri, the outer carina armed exactly 
 as there but with wider intervals between the larger spines and the

 a hardly noticeable arcuation or sinuation in the male, hardly ( ) or 
 much ( 9 ) longer than the femora, slender, armed beneath with two 
 median subapical spines besides the apical pair; spurs subaltern ate, the 
 basal at about the end of the proximal fourth of the tibia, considerably 
 longer than the tibial depth, set at an angle of about 35 with tho 
 tibia and divaricating 98-100, their apical fourth incurved ; inner 
 middle calcaria considerably longer than the outer, more than twice as

 Distinguishable from C. uhleri by the slightly different and weaker 
 armature of the carina? of the hind femora, but especially by the slen- 
 derer hind femora, and the narrower inferior sulcus of the same. I 
 probably led Mr. Blatchley into his pardonable error by determining 
 this for him as C. uhleri.

 carina with a short spine besides a long preapical spine. Middle 
 femora armed with three spines on the front carina, the preapical very 
 long, the hind carina with only a couple of very short spines besides 
 the long genicular spine. Hind femora longer than the body, two and 
 a half times as long as the fore femora, very stout but with the distal 
 portion so produced that the apical fourth is equal, the whole three 
 times as long as broad, the surface covered everywhere on the darker 
 portions, but especially on the stouter part of the femora beyond the 
 middle and within as well as without, with raised points closely crowded, 
 the outer carina elevated, armed in the middle third with a series of 
 about five spines, sometimes inequidistant, distally increasing in length, 
 the last and to some extent the others bent-arcuate, about as long as 
 the tibial spurs but coarser, followed by a rapid narrowing of the 
 femora and on this narrow portion by 4-5 minute serrulations, the 
 inner carina pretty regularly and minutely but not closely spinulate, 
 the intervening sulcus broad. Hind tibiae feebly arcuate, somewhat 
 longer than the femora, armed beneath with a single subapical spine 
 besides the apical pair ; spurs subopposite, the basal at the end of the 
 proximal fourth of the tibia, half as long again as the tibial depth, set 
 at an angle of about 45 with the tibia and divaricating 90-100, their 
 tips incurved; inner middle calcaria considerably longer than the 
 outer, fully twice as long as the others or as the spurs, and as long as 
 the first tarsal joint. Hind tarsi about two fifths as long as the tibiae, 
 the first joint hardly as long as the rest together, the second twice as 
 long as the third, but with it scarcely as long as the fourth. Cerci 
 moderately slender, rather short, probably little exceeding in length

 Body glabrous, blackish fuscous above, pallid and more or less 
 sordid luteous 011 the lower portion of the sides, with a mediodorsal 
 rufo-luteous line and dotted above faintly and rather sparsely with 
 rufo-luteous, some of the dots broadening the mediodorsal line, others 
 next the luteous sides becoming larger and sometimes more distinctly 
 luteous, and on the abdomen often becoming oblique dashes ; the very 
 edge of the inferior margins of the thoracic lobes castaneous ; antennas 
 fusco-luteous ; legs luteous, more or less infuscated, the hind femora

 as broad, the stout portion rapidly tapering so that the apical fourth 
 is subequal, the inner surface of the male with a cluster of raised points 
 beyond the middle, above, the outer carina elevated, having on the 
 middle third a row of increasingly larger spinules, the largest still 
 very much shorter than the tibial spurs, followed distally by half a 
 dozen minute and equal spinules (J 1 ) or unarmed (9), the inner 
 carina with a few small subequal spinules in the distal half, smaller

 very obscure mediodorsal line or stripe on the pronotum ; excepting 
 on the under surface of the femora, the femora and tibiae are dark 
 fuliginous and the outer side of the hind femora very dark castaneous, 
 heavily infuscated in the apical half, blackish at tip, and with deep 
 and heavy fuscous scalariform markings. The antennae are slender 
 and at least in the basal portion blackish fuscous, and the legs are 
 rather short, though the hind legs are relatively much longer in the 
 female than in the male. Fore femora not stouter than the middle 
 femora, much less than half as long as the hind femora, particularly 
 in the female, and very little longer than the pronotum, the inner 
 carina with one or two short spines. Middle femora similarly armed 
 on the front carina, the hind carina with one or two spines besides a 
 short genicular spine. Hind femora shorter (^) or longer (9) than

 long as the fore femora, in the male stout and tapering pretty regularly 
 to the genicular lobes, about two and three quarters times longer than 
 broad, the middle of the distal half of the inner surface above with a 
 small cluster of raised points, in the female much slenderer and with 
 the apical fourth subequal, the outer carina uniformly elevated, deli- 
 cately serratulo-spinous through most of its extent ((), or with a few 
 distant spinules in the outer half (9), the inner carina armed as the

 spurs, but much shorter than the first joint of the' tarsus. Hind 
 tarsi not much less than half as long as the tibiae, the first joint almost 
 as long as the rest together, the second twice as long as the third and 
 with it as long as the fourth. Cerci very short and not very slender.

 The single 9 has but one hind leg, and this has been attached

 that of the cf, it is quite possible that it does not belong to this

 be eliminated. 
 
 25. CEUTHOPHILUS FDSIFORMIS, sp. nov. 
 
 Body testaceous almost wholly overlaid with black above, the 
 abdomen wholly, the meso- and metanotum all but an anterior mesial 
 spot, and the prouotum to such a degree that the testaceous is confined 
 to a large equilateral triangular patch on each side, the inferior mar- 
 gins for their base and a couple of small mesial patches, the larger 
 behind; the lower half of the sides throughout, however, is pallid 
 testaceous ; the legs are testaceous and uniform except for rather faint 
 fuscous scalariform markings on the hind femora. The antennae are 
 slender and about three times as long as the very compact body, and 
 the legs short and not very slender. Fore femora distinctly stouter 
 than the middle femora, somewhat less than half as long as the hind 
 femora and but little longer than the pronotum, the inner carina

 more regular pattern than common, there being a moderately broad 
 mesial stripe of the brighter color, broader on the anterior than the 
 posterior part of the segments, the sides with regularly disposed flecks

 prevails on the lower portion of the sides ; on the abdomen the luteous 
 spots are usually either circular or made of short oblique dashes ; the 
 legs are as dark as the upper surface, the hind femora with the usual 
 pattern, but the lighter portions subdued in tint. The legs are rather

 Body glabrous, with a broad mediodorsal stripe of dark rufo-luteous 
 on the thoracic segments, bordered very broadly on either side with 
 blackish or blackish fuscous, fading out inferiorly, the lower portion of 
 the sides pallid luteous, more or less impure, the very margin luteo- 
 testaceous ; the abdominal segments obscurely continue these longi- 
 tudinal markings, but the black becomes brownish fuscous and is so 
 dotted with dull luteous as to give a very different appearance, the 
 segments being marked with alternate and frequent short longitudinal

 or obliquely longitudinal bars of brownish fuscous and dull luteous, 
 the darker parts often also dotted with luteous ; legs luteous, more 
 or less infuscated, especially the hind femora the outer surface 
 of which excepting at base is increasingly fuscous distally and 
 broadly annulate with blackish apically, the surface generally sprinkled 
 with luteous dots, with faintly different depths of color marking a 
 scalariform pattern. The hind tibial spines are distinctly blackish 
 at the base. The antennae are about three times as long as the body, 
 luteous, the joints at first feebly infuscated at the base, afterwards 
 wholly, and then interrupted by luteous for a single joint every few 
 joints irregularly, the legs moderately slender and not very long, the 
 hind tibial spurs distinctly infuscated or blackish at base. Fore 
 femora slightly stouter than the middle femora, considerably less than

 armed beneath with two median subapical spines besides the apical 
 pair ; spurs irregularly opposite, the basal at the end of the proximal 
 third of the tibia, slightly longer than the tibial depth, set at an angle of 
 about 45 with the tibia and divaricating about 1 20, slightly incurved

 Whole dorsal surface of body dark, being mostly almost piceous 
 with dark mahogany brown markings consisting principally of a broad 
 mesial stripe of irregular width on the thorax, fully as broad as the 
 basal joint of the antennae and on the abdomen made up of numerous 
 spots and short longitudinal or oblique bars, which toward the sides 
 become tinged with luteous ; the sides dingy luteous, the femora fusco- 
 luteous, the hind pair externally striped with clearer luteous above 
 and spotted below ; hind femoral geniculations blackish ; all the tibias

 Glabrous, castaneous, more or less, often deeply, infuscated especially 
 above, the infuscation often but not always terminating below the 
 middle of the sides, which are there sordid luteous ; a broad more or 
 less and often very obscure mediodorsal rufo-luteous stripe on the 
 pronotum, sometimes extended farther back but then generally broken ; 
 the sides of the pronotum and to a lesser extent the meso- and meta- 
 notum are more or less blotched or vermiculate with luteous, and the 
 abdomen is more or less but generally feebly maculate with luteous ; 
 the markings and the coloring vary greatly, so that it is difficult to for- 
 mulate any general statement; the female is apt to be darker than the 
 male, and specimens from New England are often almost uniformly 
 dark, even almost black, while the contrasts between the dorsum and 
 the lower portion of the sides are strongest in specimens from the 
 Middle Atlantic States, where they grow to a large size ; the legs are 
 generally luteo-castaneous, the tips of all the femora dark, sometimes 
 almost black, the hind femora with scalariform fuscous markings. 
 The antennas are not often infuscated and then generally more or less 
 or feebly annulate with luteous, slender and generally 23 times as 
 long as the body, the legs rather slender and moderately short. 
 Fore femora scarcely stouter than the middle femora, considerably less 
 than half as long as the hind femora and but very little longer than the 
 pronotum, the inner carina with a subapical spine, rarely accompa- 
 nied by another. Middle femora with 1-3 spines (largely depending 
 upon age) on the front carina, and on the hind carina 0-3 spines 
 besides a longer but short genicular spine. Hind femora two and a 
 quarter times longer than the fore femora, about as long as the body, 
 stout and tumid, the upper and lower margins almost equally arcuate, 
 scarcely more than the genicular portion subequal, almost three times 
 as long as broad, the inner surface with a very few raised points next 
 or at the upper margin beyond the middle, scarcely perceptible or 
 absent from the female, the outer carina minutely, closely, and pretty 
 uniformly serrulate through all but the basal third, sometimes almost 
 imperceptible in the female, the inner carina a feebler repetition of the 
 outer, the intervening sulcus moderate in width. Hind tibiae slender,

 with the tibia and divaricating about 100-110, their tips incurved; 
 inner middle calcaria considerably longer than the outer, about twice

 Color and markings almost precisely the same as in G. terrestris, so 
 that imperfect and immature specimens are exceedingly difficult to 
 separate ; but the darker markings in this species are as a rule darker 
 and cover the surface to a greater extent, and when the mediodorsal 
 stripe is present it is often broader and extends upon the meso- and 
 metanotum ; on the other hand, the maculation of the abdomen with 
 luteous is usually more striking in the present species (partly from 
 the darkness of the ground) and forms sometimes a tolerably regular 
 pattern, consisting on each joint of an anterior mediodorsal triangular 
 spot, a central subdorsal oblique dash, and posterior spots farther from 
 the middle line. The antennae are from two to three times as long as 
 the body, and slender except at extreme base, and the legs are 
 moderately long. Fore femora no stouter than the middle femora, a 
 little more than a fourth longer than the pronotum and much less than 
 half as long as the hind femora, the inner carina with a long subapical 
 spine and occasionally an additional one. Middle femora with 0-2 
 spines besides a rather long subapical spine on the front carina, and 
 on the hind carina an occasional small spine besides a long genicular 
 spine. Hind femora of about the length of the body, three and a half 
 times as long as broad, about two and a third times as long as the fore 
 femora, moderately stout at base, the distal fifth subequal, with no 
 raised points on the upper or inner surface, the outer carina with 
 about thirteen unequal coarse spines, the longest hardly half as long as 
 the tibial spurs ()or with minute distant inconspicuous spinules (9),

 the inner carina with similar but uniform spinulation, none so large 
 as on the outer carina (<J) or with a few minute spinules on the 
 apical half (9), the intervening sulcus not very broad. Hind tibiae 
 feebly undulate in the basal half in the male, slender in both sexes, dis- 
 tinctly but not greatly longer than the femora, armed beneath with a 
 single preapical spine or occasionally with two minute unaligned 
 spines besides the apical pair ; spurs rudely opposite, the basal at the 
 end of the proximal third of the tibia, more than half as long again as 
 the tibial depth, set at an angle of about 40 with the tibia and divari- 
 cating 90-100, their tips incurved ; inner and outer middle calcaria 
 subequal, more than twice as long as the others or as the spurs, and as 
 long as the first tarsal joint. Hind tarsi about two fifths as long as 
 the tibiae, the first joint shorter than the rest together, the second twice 
 as long as the third and with it longer than the fourth. Cerci stout 
 in the proximal half, tapering beyond, about two thirds as long as the 
 femoral breadth. Ovipositor nearly two thirds as long as the hind 
 femora, shaped and armed as in C. terreslris.

 tiuge ; the markings consist of a mediodorsal stripe of varying width 
 but usually rather broad on the prouotum, especially a little before 
 either border, generally reduced to a line on the abdomen, a large 
 lateral patch on either side of the pronotum, sometimes confined to the 
 inferior margin, sometimes extending half way to the mediodorsal line,

 more or less elongated longitudinally, especially on the abdomen ; the 
 antennae are pale fuscous and the legs sordid luteous more or less 
 infuscated, the hind femora with heavy fuscous scalariform markings, 
 leaving roundish dull luteous spots in the openings of the upper half.

 fuscous band on either side, leaving between them a broad bright stripe 
 the whole length of the body, next the stripe sharply delimited, later- 
 ally more or less broken, ragged and fading away, narrow on the pro-

 the sides, broader and profusely spotted with luteous posteriorly, the 
 lower portions of the sides almost wholly pallid luteous with cloudy 
 infuscations, the extreme margin testaceous ; legs luteo-testaceous, the 
 hind femora feebly marked with fuscous in a scalariform pattern and

 Luteo-castaneous, heavily marked with blackish fuscous especially 
 along the posterior borders of all the segments and the anterior border 
 of the pronotum, and the latter also flecked with it in an obscure 
 fashion upon the whole disk ; legs luteous, the hind femora almost 
 lacking the usual scalariform markings. The antennae are slender,

 joint nearly as long as the rest together, the second fully twice as long 
 as the third and with it as long as the fourth. Cerci very short, not 
 very slender, rapidly tapering, hardly more than half as long as the 
 femoral breadth (9) or developed basally as a single stout sub- 
 clavate apically upturned blunt joint, surmounted by a brief conical 
 multiarticulate appendage, the only portion which surpasses the supra-

 Dark luteo-testaceous, more or less infuscated especially along the 
 hind borders of all the segments and the front border of the pronotum ; 
 occasionally a few indistinct luteous dots occur in a transverse series 
 on the abdominal segments, but most of the varied markings are con- 
 fined to the pronotum, where they are not pronounced and consist of 
 a dull luteous mediodorsal stripe and vague and irregular streaks or 
 clouds of luteous upon either side, more or less extensive ; the legs 
 are generally lighter than the body, but are more or less infuscated 
 beyond the base of the femora, the hind pair of which scarcely show 
 any scalariform markings. The antennae are not very slender, two to 
 three times as long as the body, and the legs are moderately long and

 Obscure brownish fuscous, with luteous markings which are very 
 dull and inconspicuous except in the bordering of the inferior margins 
 of the thoracic segments ; they are mostly found in large blotches of 
 very irregular form on the sides of the pronotum and in smaller lateral 
 and dorsal anterior spots on the other segments, sometimes confluent 
 and the lateral often crossing the abdominal segments ; there is some- 
 times an interrupted mediodorsal thread ; legs luteous, much infuscated 
 especially on either side of the femoro-tibial articulation, the hind 
 femora very broadly marked with blackish fuscous in a scalariform 
 pattern. The antennne are slender and about three times as long as 
 the body, and the legs slender but not very long. Fore femora no 
 stouter than the middle pair, much less than half as long as the hind 
 femora and only about a sixth longer than the pronotum, the inner

 Body luteous, more or less infuscated in irregular patches which 
 especially form broad bands on the posterior margins of the segments 
 and leave the pronotum irregularly blotched, the fuscous portions 
 occupying the anterior and posterior and usually also the lateral mar- 
 gins, sometimes broken along the middle line, and running backward 
 from the anterior margins in a pair of large subdorsal stripes, the 
 fuscous portions often dotted with distinct luteous dots. The hind 
 femora are marked in the usual compound scalariform manner with 
 fuscous, which unites distally in two elongate patches on the lower half 
 of the outer surface. Antennae more than twice as long as the body, 
 not very slender. Legs moderately long. Fore femora distinctly 
 broader than the middle femora, a fifth longer than the pronotum, and

 Very pallid luteous, marked with fuscous and blackish fuscous, the 
 latter in the posterior bordering of all the segments, the former in 
 obscure blotches on the pronotum and along its front margin, more 
 obscure in some specimens than in others; a mediodorsal luteous 
 thread breaks most of the fuscous markings of the body ; the legs are 
 very pallid luteous, sometimes infuscated on the distal portions of the 
 femora and especially in scalariform markings, never deep, upon the 
 hind femora ; the spines of the legs are all dusky tipped ; eyes black. 
 The antenme are slender and from twice to thrice the length of the 
 body, and the legs are rather long and slender. Fore femora scarcely 
 if any broader than the middle femora, about a fifth longer than the 
 pronotum and half as long as the hind femora, the inner carina with a 
 subapical spine sometimes accompanied by a shorter spine. Middle 
 femora with 4-5 delicate spines, the subapical longer than the others 
 on the front carina, and on the hind a similar series be-ides a not very 
 long genicular spine. Hind femora much shorter than the body, twice 
 as long as the fore femora, rather slender, being about three and a half 
 times longer than broad, tapering pretty regularly to the tip with no 
 genicular swelling, the surface with a few very scattered raised points

 Of mingled fuscous and luteo-castaneous, sometimes one, sometimes 
 the other prevailing ; when it is the latter, the fuscous shows itself on 
 either side of the mediodorsal line in a series of subtriangular sub- 
 dorsal patches seated upon the posterior margin of the segments, much 
 larger on the thoracic than on the abdominal and partially or wholly 
 absent from some of the latter ; besides there is a series of lateral 
 blotches, just failing to reach the lower margins of the nota and more 
 extended on each segment anteriorly than posteriorly ; on the pro- 
 notum these two sets blend irregularly, so that here the darker colors 
 prevail ; the hind femora are more or less infuscated with the mark- 
 ings common to the genus, more or less distinct, the geniculations 
 laterally blackish. Antennae moderately stout. Legs not very elongate. 
 Fore femora basally somewhat stouter than the middle femora, con-

 lows : a mediodorsal series of moderately large roundish spots, two 
 on the pronotum and one on each of the succeeding segments more or

 less distinctly connected by a luteous thread ; on the middle of each 
 side of each segment a transverse dash, on the abdominal segments 
 more elongated than on the thoracic, and generally partly merged in 
 the mediodorsal spot, on the pronotum larger than elsewhere and ac- 
 companied by some outlying dots ; also as an inferior margining of the 
 thoracic segments ; but all these markings may become so enlarged as to 
 make the surface prevailingly luteous ; the femora are fuscous, becom- 
 ing lutescent toward the base, on the hind pair as heavy scalariform 
 markings, on the anterior pairs as slender stripes. The antennae are 
 brownish luteous, rather slender and apparently about three times 
 the length of the body, the legs rather short and slender. Fore 
 femora no stouter than the middle femora, less than a fourth longer 
 than the pronotum, much less than half as long as the hind femora, 
 the inner carina with a long subapical spine, sometimes accompanied 
 by another minute spine. Middle femora with a very long subapical 
 spine accompanied by a smaller one on the front carina, and the hind 
 carina with a long genicular spine only. Hind femora much shorter 
 than the body, but about two and a quarter times longer than the fore 
 femora, rather slender, being nearly three and a quarter times longer 
 than broad, the apical fourth subequal, the surface with a few raised 
 points scattered here and there beyond the middle of the upper 
 half of the femora both inside and outside, the outer carina with seven 
 or eight small unequal and inequidistant recumbent denticulations on 
 the apical half (<J) or apparently unarmed (9), the inner carina with 
 some very distant and very slight serrulations, the intervening sulcus 
 slender. Hind tibiae straight in both sexes, distinctly longer than the 
 femora, slender, armed beneath with a single preapical spine besides 
 the apical pair ; spurs subopposite, fully twice as long as the tibial 
 depth, set at an angle of about 35-45 with the tibia, and divaricating 
 about 90-100, their tips considerably incurved ; inner middle calcaria 
 scarcely longer than the outer, more than twice as long as the others, 
 nearly twice as long as the spurs and about as long as the first tarsal 
 joint. Hind tarsi two fifths the length of the tibiae, the first joint fully 
 as long as the rest together, the second more than twice as long as the 
 third and with it nearly or quite as long as the fourth. Cerci rather 
 slender, tapering regularly, about as long as the femoral breadth. 
 Ovipositor more than two thirds as long as the hind femora, straight, 
 beyond the proximal third very slender, the tip upturned abruptly 
 and produced to an aculeate point, the teeth of the inner valves acu- 
 leate, pretty long and arcuate.

 Body bright luteous, heavily marked with blackish fuscous ; on the 
 pronotum the markings are very irregular, but consist in the main of 
 the following : on either side of the front margin a large transverse 
 fuscous spot, which reaches neither the mediodorsal line nor the lateral 
 margin and is interrupted below by a roundish spot and above by the 
 incursion from the anterior margin of a short narrowing dash; in 
 the middle of the dorsum a quadrate spot divided by a mediodorsal 
 luteous line into a pair of longitudinal bars, each connected anteriorly 
 with the before mentioned anterior spot, and leaving a luteous sub- 
 marginal anterior mediodorsal spot ; an infero-posterior black spot not 
 touching! the margin ; and a laterodorsal subtriangular spot on the 
 posterior margin ; on the succeeding thoracic segments, and on the 
 abdominal there is a series of large irregularly triangular laterodorsal 
 spots on the posterior margins, and another lateral series of roundish 
 or transverse spots generally not reaching any margin ; the legs are 
 luteous, the fore and middle femora more or less infuscated in longi- 
 tudinal streaks, the hind femora dull luteous with scalariform fuscous 
 markings. Antennae moderately slender, about twice the length of 
 the body, the legs moderately long. Fore femora scarcely stouter 
 than the middle femora, less than a fifth longer than the pronotum, 
 much less than half as long as the hind femora, the inner carina with 
 a tolerably long subapical spine sometimes accompanied by another

 carina, accompanied at least in the male by a couple of others smaller, 
 and on the hind carina one or two short spines at least in the male, 
 accompanied by a long genicular spine. Hind femora moderately 
 slender, fully three times as long as broad, two and a third times 
 longer than the fore femora, the surface with a few scattered raised 
 points on the distal half and especially along the upper edge of the 
 inner surface, the outer carina with 6-8 very unequal and inequidistant

 Varying from light to dark castaneous with very feeble markings, 
 excepting usually a greater or less degree of infuscatiou along the 
 posterior margins of all the segments and the anterior margin of the 
 pronotum ; the pronotum is also sometimes feebly enlivened with ver- 
 iniculate fuliginous markings and not infrequently a faint luteous line 
 may be traced along the middle of the dorsum, often conspicuous on 
 the pronotum and always slender ; the legs are concolorous with the

 Luteous, heavily irrorate with more or less confluent fuscous dots, 
 giving it, as Thomas well expresses it, a mossy appearance ; the 
 amount of confluence and accordingly of infuscation varies somewhat 
 in different individuals, and is usually deepest on the pronotum, which 
 also often shows on either side a larger or smaller rufo-luteous patch 
 free from dots ; the hind femora retain the usual scalariform markings, 
 which are narrower than common. Antennae moderately stout at 
 base, very slender beyond, three or four times as long as the body. 
 Legs rather short. Fore femora scarcely stouter than the middle 
 femora, about a fourth longer than the pronotum and much less than 
 half as long as the hind femora, the inner carina with a long subapical 
 spine. Middle femora with a long subapical spine on the front carina 
 sometimes accompanied by 12 shorter ones, the hind carina with a 
 single subapical spine besides the genicular spine. Hind femora 
 almost as long as the body, considerably more than twice as long as 
 the fore femora, very stout, apically tapering rapidly especially in the 
 g , the distal fifth subequal, about two and a half times longer than 
 broad ( $ ), the darker portions heavily scabrous with raised points, 
 besides a sparse sprinkling of the same on the apical half of the inner 
 surface, the outer carina minutely and bluntly bi- or tri-serrulate, 
 sometimes with a large preapical triangular dentiform spine serrulate 
 on its proximal edge (<?) or unarmed (9), the inner carina similar 
 but in the distal half more coarsely uniserrulate, the serration stopping 
 abruptly before the apex with a distinct denticle, sometimes produced 
 to a stout triangular spine, serrulate on the proximal edge (<?) or with

 with the tibia and divaricating but little more than that, the tips feebly 
 incurved ; inner middle calcaria slightly longer than the outer, more 
 than twice as long as the others or as the spurs, and as long as the first

 The male of this species is remarkable for the surface sculpture of 
 the dorsum of the abdomen, the first seven segments of which, but 
 particularly the second to the sixth inclusive, are densely covered with 
 minute strongly .elevated tubercles, besides which on the anterior por- 
 tion of the first to the fifth segments and almost crossing the segment 
 is a mesial series of large slightly transverse tumid elevations, rounded 
 anteriorly, truncate posteriorly. I have seen nothing resembling it in 
 any other species, excepting to a less degree in its next neighbor, 
 C. pacificus ; this and the peculiar characteristics of the outer hind 
 femoral carina make this a very striking species, which I take pleasure 
 in dedicating to my colleague, Mr. Samuel Henshaw. 
 
 54. CEUTHOPHILUS DEVIUS, sp. nov. 
 
 Nearly uniform brownish testaceous, subglabrous, with very feeble 
 infuscated obscure blotches especially upon the pronotum, and a fine 
 mediodorsal luteous thread running the length of the body ; surface, 
 especially in $ and particularly on the thorax, very finely sub- 
 corrugate. The antennae are coarse at base (beyond broken), the 
 joints more or less thickened apically. The legs are rather short. 
 Fore femora much less than half the length of the body, hardly a fifth 
 longer than the pronotum, a little stouter than the middle femora and 
 a little less than half as long as the hind femora, the inner carina with 
 a preapical spine and a few (9) or many (<J) spinous points; the fore 
 tibiae with a single median spine on the inner side above, and beneath 
 with 3 (9) or 4 ( ) pairs of stout spines. Middle femora with 56 
 (9) or 8-9 ((J) spines on the fropt carina, the preapical small, at least 
 in the , the hind carina similarly armed and with a small genicular 
 spine. Hind femora considerably shorter than the body, distinctly 
 more than twice the length of the fore femora, nearly straight above 
 in the $ where they are of nearly equal breadth on the proximal two 
 thirds and are then somewhat abruptly emarginate beneath, less than 
 three and a half times as long as broad in both sexes, the surface 
 glabrous with no raised points excepting sparsely scattered ones on 
 the upper surface in the middle half, the outer carina of both sexes 
 with equal slight denticulations on the constricted portion of the 
 femora, the inner carina with larger denticulations throughout (except 
 at base) much larger and more unequal in the <J, where the largest

 By the brevity of the first and second hind tarsal joints and the 
 slight enlargement of the fore tibiae in the male, this species approaches 
 the genus Phrixocnemis, but the normal development of the armature 
 of the hind tibiae forbids placing it there. 
 
 55. CEUTHOPHILUS NEOMEXICANUS, sp. nov. 
 
 Dark testaceous or castaneous, glabrous, broadly but gradually 
 infuscated, especially above, on the posterior margins of all the seg- 
 ments, and on the anterior portion of the pronotum, which is otherwise 
 more or less slightly mottled, beneath and on the lower portions of the 
 sides invariably lighter and generally more nearly unicolorous. Legs 
 testaceous, the hind femora externally with a feeble median longi- 
 tudinal infuscation sometimes visible only on the distal half, where it 
 is often diffused and accompanied by feeble slender herring-bone 
 iufuscations on either side, the hind tibial spines feebly infuscated at 
 apex. The antennae are not very slender and the legs short. Fore 
 femora distinctly stouter than the middle femora, but little longer than

 hind carina similarly armed, but one spine genicular and the others as 
 numerous in the <J as in the . Hind femora much shorter than the 
 body, considerably more than twice as long as the fore femora, stout, 
 being in the $ less than three times as long as broad, with hardly any 
 subapical constriction, that is, tapering almost regularly to the apex, 
 the surface with no raised points, the outer carina pretty regularly and 
 rather minutely denticulate in the distal half or less, exclusive of the 
 geniculation (<J), or minutely denticulate throughout (9), the inner 
 carina similar to the outer, but in the $ more extensively denticulate 
 than the outer, the intervening sulcus narrow. Hind tibiae straight in 
 both sexes, distinctly shorter than the femora, the upper surface 
 rather broad in the <J and basally constricted, beneath with a longer 
 ( $ ) or shorter ( 9 ) series of median spines, besides the apical pair ; 
 spurs subopposite, the basal pair at the end of the proximal third of 
 the tibia (),* about as long as the tibial depth ($), or two to three 
 times as long as the tibial depth (9), set at an angle of about 50 
 (cJ) or 30 (9) with the tibia and divaricating as much, their tips 
 scarcely incurved ; inner middle calcaria not greatly longer than the 
 outer, less than half as long again as the others or as the (<) spurs, 
 nearly as long as the first tarsal joint. Hind tarsi much less than 
 two fifths as long as the tibia, the first joint not so long as the rest 
 together, the second but little longer than the third and with it a little 
 shorter than the fourth. Cerci rather slender and regularly tapering, 
 pointed, considerably shorter (<) or considerably longer (9) than 
 the hind femoral breadth. Ovipositor about two thirds as long as the 
 hind femora, its upper margin feebly arcuate, the apical two thirds 
 subequal, the apex slightly upturned and very acuminate, the teeth of 
 the inner valves long, aciculate, the distal arcuate.

 The species is most nearly allied to G. devius, from which it differs 
 principally in its smaller size and the armature of the femora. 
 
 The single 9 I have seen has four pairs of spurs on one tibia, the basal 
 pair at the end of the proximal fourth of the tibia, while the other tibia has but 
 a single non-opposite pair in the middle of the tibia. It is further anomalous in 
 the excessive length of the spurs, in contrast to the $ .

 I cannot find any species which corresponds sufficiently with Halde-

 PHRIXOCNEMIS (<ptos, /cn^t?;), Gen. nov. 
 
 Closely allied to Ceuthophilus, and having its general aspect, though 
 the legs are stouter than is commonly the case in that genus. Head 
 rather large, the vertex well rounded and deflexed, barely interrupted 
 from continuation into the frontal costa by the confluence of the 
 antennal scrobes. Eyes small, subpyriform, as large as the antennal 
 scrobes. Antennae as in Ceuthophilus. Palpi very small, the ante- 
 penultimate joint but little shorter than those on either side of it. 
 Pronotum sub-semicylindrical, the inferior margin of the descending 
 lateral lobes arcuate, the anterior and posterior angles equally or 
 almost equally rounded ; those of the meso- and metanotum similarly 
 rounded without the posterior oblique truncation common in Ceutho- 
 philus, or present in the slightest degree. Anterior coxas compressed 
 and elevated to form a median denticle. Legs short and rather stout. 
 Fore femora stout, or at least broad by compression. Middle femora 
 unarmed apically, or, when armed, only by an inferior and brief spine

 very broad and incrassate, even the extremity stout, both inferior 
 carinae feebly denticulate, rarely with any conspicuous spines. Fore 
 tibiae unarmed above, enlarged in the male ; middle tibiae armed above 
 with several pairs of spines besides those beneath ; hind tibiae stout, no 
 longer than hind femora, armed beneath with a single apical spine 
 besides the apical pair and above with lateral spines of two classes : 
 a larger series of generally long stout spines, longer than the calcaria, 
 and, especially in the 9> becoming longer and more crowded apically, 
 the 46 spines of one row not greatly divergent from those of the 
 other ; and minute denticulations occupying the interspaces, at least on 
 the proximal half of the tibia and the proximal free portion, but, at 
 least in the 9 , commonly absent from the distal half of the tibia ; the 
 three pairs of apical calcaria are not widely different in length. Hind 
 tarsi short, much less than half as long as the tibiaa, the first and fourth 
 joints, and the second and third joints, respectively subequal, the latter 
 together much shorter than either of the others. Ovipositor equal in 
 breadth throughout, when viewed laterally scarcely or not taperiug in 
 the basal half.

 degree upon the whole dorsum, made more evident by a fine medio- 
 dorsal luteous thread down the whole body, the legs of the body color, 
 but the apical half of the femora more or less though at most feebly

 with miuute denticulations, the intervening sulcus not broad. Hind 
 tibiae considerably shorter than the femora, straight, stout, armed 
 beneath with a single small preapical spine, besides the unusually long 
 apical pair ; the four pairs of spurs are opposite or subopposite, the 
 basal near the end of the proximal third of the tibia, regularly increas- 
 ing in length distally, so that the last are as long as the nearest calcaria, 
 while the proximal are but little more than half that length or than 
 the tibial depth, set at an angle of 70-80 with the tibia and divaricat- 
 ing only about 20, the whole feebly incurved, the tips not more so ; 
 the spurs are also more closely crowded on the distal half of the tibia 
 than before it, and indeed so crowded as to have no intervening spines, 
 which even between the others are few in number and irregular, the 
 two distal spurs with the proximal calcaria being at uniform distances 
 apart, a distance hardly one half that which separates the preceding 
 spurs ; all the calcaria are subequal in length, those of opposite sides 
 similar, but they decrease slightly from above downwards, and the 
 longest is as long as the first to third tarsal joints combined. Hind 
 tarsi hardly more than a third as long as the tibiae, the first and fourth 
 joints subequal and either of them much longer than the subequal 
 second and third joints combined. Cerci moderately stout, equal and

 This genus is remarkable for lacking the third tarsal joint of the 
 fore and hind legs. Brunner (Monogr. Stenop., 60, foot-note) pre- 
 sumed this to be an abnormal condition found in a single specimen 
 seen by me ; but it was seen and specially remarked upon both by 
 Haldeman and Girard before me, and I have examined fourteen speci- 
 mens of both sexes, all of which agree in this particular except that 
 in two or three of them the fore or hind tarsi, or both, are broken, 
 so that it cannot be affirmed of them. There can be no question that 
 it is normal as no specimen of the two species has been found in which 
 the condition was different.

 fore extends along the eastern margin of the Rocky Mts. from Lat. 
 34 to 44 N.

 The specimens described by me as a Ceuthophilus belong to this 
 species, though separately described at the same time. 
 
 Specimens are recorded as having been taken, or have been seen 
 by me, from Perry Co., 111., Dr. E. R. Boardman (Uhler) ; Illi- 
 nois (Uhler, Comstock, McNeill) ; Southern Illinois and Rock 
 Island, 111. (Uhler) ; Red River, Manitoba (Caulfield) ; Carbery, 
 Manitoba, in the gizzard of a sparrowhawk (Fletcher) ; Northern 
 Minnesota, leaping about in the grass at midday (Scudder) ; Denison, 
 Crawford Co., Iowa, July 13, 15, 20 (J. A. Allen) ; Iowa (Osborn) ; 
 Nebraska City and the Platte Valley, Nebr. (F. V. Hayden) ; Ne- 
 braska City, West Point, and Pine Ridge, Nebr. (Bruner) ; Northeast 
 Nebraska (Bruuer) ; Berber Co., Kans., and Topeka, Kans., Cragin 
 (Bruner); Missouri (Broadhead) ; Sedalia, Mo. (U. S. Nat. Mus.) ; 
 Dakota (Bruner), and Colorado, 5,000' (Morrison) ; so that its general 
 range appears to be between the Mississippi River or a little east of 
 the main stream to the Rocky Mountains between Lat. 37 and 50 
 North. But I have two specimens in my collection, one from North 
 Carolina (Shute), the other from El Dorado Co., Calif., 4,000' (Giss- 
 ler), both of them far beyond the otherwise known limits of the 
 species. Of the latter locality I entertain no doubt, especially as I 
 have recently found in the Museum of Comparative Zoology a single 
 specimen collected by Morrison in Arizona; but as to the former I am 
 inclined to believe the label became accidentally attached to the wrong 
 insect, particularly as Shute's collection was made on the seaboard.

 APPENDIX. 
 
 After this paper was in type, I received from the Davenport Academy 
 of Natural Sciences, through the kind intervention of Prof. Herbert 
 Osborn, of Ames, Iowa, the single type of Ceuthophilus utahensis 
 Thorn, (see p. 102), and append a description of it to render this paper 
 more complete. It is not so closely related to C. valgus as I had sup- 
 posed from the description and figure, but belongs rather in the near 
 vicinity of G. uhleri and C. blatchleyi, though with the inferior sulcus 
 of the hind femora not so exceptionally broad as in those species, and 
 also with very different markings, in which respect it recalls rather 
 C.pallidus. The measurement of the hind tibiae given by Thomas 
 is too great. The specimen was collected in alcohol, but has since 
 been pinned. 
 
 Brownish fuscous with dull luteous markings ; on the pronotum the 
 fuscous borders all the margins broadly, the anterior and lateral mar- 
 gins very broadly, sending backward from in front a broad mediodorsal 
 stripe nearly meeting the posterior bordering, and through it runs a 
 faint median luteous thread ; the posterior bordering throws forward 
 on either side a subdorsal tooth embracing the posterior end of the 
 mediodorsal stripe and leaving between the two a U-shaped luteous 
 mark which connects the luteous disks of either side, the latter of 
 which are more or less mottled with fuscous lines ; the me'so- and 
 metanotum are heavily spotted anteriorly with partly confluent luteous 
 spots, and the abdominal segments are more regularly margined an- 
 teriorly with luteous ; legs warm luteous, the hind femora with the 
 usual scalariform infuscations. The antennae are moderately slender 
 and more than twice, probably thrice, as long as the body, and the 
 legs moderately long. Fore femora no stouter than the middle femora, 
 a little less than half as long as the hind femora, scarcely more than a 
 third longer than the pronotum, the inner carina with a moderately 
 long preapical spine preceded by a shorter one. Middle femora with 
 a single moderately long spine on the front carina and on the hind 
 carina 1-2 short spines besides a moderate genicular spine. Hind 
 femora nearly as long as the body, somewhat more than twice as long 
 as the fore femora, moderately stout, only the distal sixth subequal, 
 about three and a quarter times as long as broad, the surface with a 
 very few raised points along the upper edge of the inner side, the 
 outer carina considerably and subequally elevated, with about fifteen 
 coarse but rather small subequal and inequidistant spines, the longest
 
 SCUDDER. NORTH AMERICAN CEUTHOPHILI. 113 
 
 not a third as long as the tibial spurs, the inner carina with a series of 
 rather distant short spinules partially biseriate, the intervening sulcus 
 broad, equal, and deep. Hind tibiae rather feebly and broadly sinuate 
 (this point is exaggerated in the original figure), a very little longer 
 than the femora, armed beneath with a single long preapical spine 
 besides the apical pair ; spurs subalternate, the basal beyond the end 
 of the proximal third of the tibia, nearly twice as long as the tibial 
 depth, set at an angle of about 35 with the tibia and divaricating 
 about 80, their apical third or fourth considerably incurved ; inner 
 middle calcaria considerably longer than the outer, fully twice as long 
 as the others or as the spurs, but somewhat shorter than the first tarsal 
 joint. Hind tarsi about two fifths as long as the tibiae, the first joint 
 as long as the rest together, the second and fourth subequal, and each 
 about twice as long as the third. Cerci rather stout, tapering regu- 
 larly, about as long as the femoral breadth. 
 
 Length of body, 14.5 mm. ; antennae, 31+ mm. ; pronotum, 4.4 mm. ; 
 fore femora, 6 mm. ; hind femora, 13 mm. ; hind tibiae, 13.5 mm.
