 of the original copy and in keeping with the 
 filming contract specifications. 
 
 Original copies In printed paper covers are filmed 
 beginning with the front cover and ending on 
 the last page with a printed or illustrated impres- 
 sion, or the back cover when appropriate. Ail 
 other original copies are filmed beginning on the 
 first page with a printed or illustrated Impres- 
 sion, and ending on the last page with a printed 
 or illustrated impression. 
 
 The last recorded frame on each microfiche 
 shall contain the symbol — »> (meaning "COiV- 
 TIIMUED"), or the symbol V (meaning "END"), 
 whichever applies. 
 
 IVIaps, plates, charts, etc.. may be filmed at 
 different reduction ratios. Those too large to be 
 entirely included in one exposure are filmed 
 beginning in the upper left hand corner, left to 
 right and top to bottom, as many frames as 
 required. The following diagrams illustrate the 
 method:

 The anterior ])ortion of the liody is called tin' lirod : it varies 
 frreatly in form, and is Joined hy memlirane to the protliorax. 
 Usually (lie hirid i)ortion is Ijiil slifjlitly narrowed, and enters the 
 iintei'ior part nf tin,' protliorax; sometimes the pari l)(diin(l the- 
 eyes is suddenly narrowed iiiid eonstricteil, fdrminj;' ;i neck. .>r

 protliorax hy a semiulolmliir condyle, as in sonic ('arai)idie and 
 tiie JJrenthidie. 
 
 The siirfaei' of the head consists of a solid horny plate; above, 
 it is frccpieiitly marked by a siniile suture, rnnniim' transversclv 
 between or ill front of the antenna' ; this is callcij (he </i//ii'(il cir 
 /'roiildl .111/ lire. The portion in front of this siitnre, when dihitcd 
 so as to jiroject over the moutli, as in many Scaraba'idie, is called 
 the rli//i)'iiti: when small it is named I'/iislmtKi. and is sometimes 
 iiieinbranoiis or coriaceous, instead of horny like llic rest cf the 
 surface. 'I'lie anterior pnrlion of tnc head is sonicl imc.s prolonu'i'd. 
 so that tho distance belwecn the eyes and iiiniiih parts is greater 
 in len;.i'th than the rest of the head; when thus fnrnicd the head 
 is called roMralr. and the proloiiired portion the ros/rnrii or In'ii/r. 
 The /■o,>'/;v/ HI varies frreatly in form and Iciiii'lh; it is often mil 
 narrower than the head and oven shorter, rarely, as in IJalaiiinus, 
 very slemler, alnmst lilifonn, and as lon;a' as the entire body. The 
 presence of the rostrum is (piite fi^tuieral in the sub-order Mhvii- 
 chophora, l)ut not cliaraetcristi(; of it, as the rostrniii is dltcu 
 absent her(! unci present in other isolated genera of the Coleijfi-

 4. LaincHiilc: In lliis l}i)0 tiio outer joints are prolonged ante- 
 riorly, opposing Hat suri'act's to eaeli otlier, wliidi may •<(• hronglit 
 closely in I'lmlaci, I'orniing thus a transverse, or rarely i(jun(le(i, 
 elub, Kiippoiled at one side liy llie stem of liie antenna,'. Tliis 
 lorm obtains in all Searabiuidie. 
 
 Oilier modiliealions have hi'en named, but, with the e.\eeption 
 of two, tliese liave not been used in the present treatise. Tiiey 
 are, the irri'ijuldr and ((ijiilluri/. The lirsl name is ajiplied to 
 those antennie in which ceruiin of the joints have an iinnsmd (jr 
 extraordinary dcveloi)ment, as in t!ie (/yrinidie or I'latyp.syllidie; 
 when, liowever, the irregularity is sexinil, as in the males of some 
 Meloe, the antenna' are said to lie (Itjor-iiirtl in that se.\. The 
 capillari/ form is a modification of the clavale type, in which the 
 joints are long, slemler, and hair-like, and very luosely artieulated, 
 as in many Triehopterygidie, some Scaphidiidiu, and in l)asyeerus. 
 in this i'orm the joints are fretpiently surrounded at tip with a 
 circle of longer hairs, in wliith ca.-n; the aiiti'iiiia' are said to be 
 ri'riirclldlc. 
 
 Aiiteiiiiie are called (ji'iHi-ntiiti' when thi' second joint is ufli.xed 
 so as to malic an angle wiili the first; the following joints eoii- 
 timiing in the line of the second. In this form the lirst or basal 
 joint is usually niueli longer, and is called the .<c<ipr. \N'lieii the 
 geniculate form is at the same time capitate, the joints interme- 
 diate iietween tiie scape and club are ealle(i tho J'lniiclt;. Tliesi' 
 terms are used more especially in the Khyiiehopliorous series, in 
 which the gcniculatc-i'hivate type is the most common form of 
 antenna'. 
 
 Moirii. — The month of Coleoptera is mamiibnlate; that is to 
 sav, it }!(' scs.~es two jiairs of lun'izonlally moving |iieces for the 
 jiiirposc (if seizing the food. Aliove the inoiith there is usually 
 a small piece, iiioi'e <ir less transverse, articulating with the epi- 
 stonia, which is called the iijiper lip or liilirniii. 
 
 The Idliriiiii is variable in foriu, and in nearly all the families 
 of normal Coleoptera is distinctly visible. It may, iiovvever, be 
 I'oiiipleti'ly united with the epistoma, lU' retracted beneath it, and 
 thus entirely concealed. In the rihyiichophiu'a, excepting Itliino- 
 maeeridie, riatypodiiue, ami .\nlhribidu', the labriim is entirely 
 wanliiitf.

 from tlie po.-ilioii of tile condyles and llie strucnire of tlio sides 
 of the lip of the rostriini, the motion is vertiuul. 
 
 Tile form and structure of liic maiidihles are of gTcat moment

 cieiitly (I'linile without fiirlher explanation. The niandil)les of

 in the Oliorhynchidaj the inaiidililes are provided with a 
 deciiluoii> cu>p of varyiiij^' form and .-ize. wiiicli, in most cases, 
 is lost soon after the insecL reaches the mature condition. After

 or. miu'(> eoiiiiiioiily, on llu' face of tiie luaiidihle itself. 
 
 IJelow the maiidil)les is a second pair of horizontally niovinjr

 ons work of the lahoralory and liUrary. are aware (d' the iimnense 
 dillieidty of dealing with comph'xes containing ^U(di vast muidiers 
 of species as tlio>e \vhi( h constitute the ])rineipal inject types. 
 'The siiecies representid in the cidleclions of the anihors of this 
 treatise are from our restricted fauna nmre than ll.ddo in iuiinl)er. 
 
 The eiillectiou and the oliscrvation iu the field (»f tlies(^ sniull,

 for sysleniatic or economic science, in so far as that they aid hnt 
 little in forming the (da>silicaliou and stalile noineiiclature, upon 
 which the knowledge of the ohjecis treated of must rest, in urdcr

 OlislhapHs does to the Lebiini. 
 
 A study of tiie form of the lignla and paraglossa; of those 
 gcnira which are acknowledged on all sides to be undoubtetl 
 mendicrs of the presiint tribe J'ldli/iiiis, Valal/nis, and OliMho- 
 jiiiK. seems to .show wiiat little value these organs have in the 
 deliiiitiou of tribes and gi'oups of genera. The ligula of Olis- 
 Iho/ms is very plainly that of many Lebiidcs, /'Idti/iiim reproduces 
 Very closely that of J'liu-oxlichux, Cdlallnix proper is as nearly as 
 pos^iliie intermediate betwi'cn the two, while the section I'nxln- 
 darltjla is a inodilication of I'hih/inis. The tip of the ligida is 
 frceii I'lalijnux and l'risfii(l(i(li/lii,i\u{\ not free in theothergencra. 
 
 Tnc menium tooth also seems to furnish characters of an 
 evrjiescent nature. In some /'/(//_)//(?/«, especially those in which 
 the hind angles of the thorax arc distinct {hnaiitromartiiiiahis, 
 ovi/Ktinit^, etc ), the tooth is longitudinally impi'cssed and emar- 
 ginate at tip, while in the A'joninn type the tooth is very obtuse. 
 The sam(! variation is observ(Ml in (Uthilhux, some having (juitc 
 an acute tooth, others even bilid.

 Olis/fid/iiix is rei)r<'s('iiti'd in tlio Atlantic region hy two species; 
 the olIiiT genera occur on liotli sides of tin^ continent. Of I'n'n- 
 loiii/cliiis two species arc known, both of them identical witlt 
 JMiropeiin forms (coiiiit/aiiiifiis and frrrirola), and \mvr, probal)ly 
 been introduced, (lie first ineulioued being ratiier widely spread 
 by coniiuerce over the globe. 
 
 <iroup 11. — Perigonse. 
 
 This group is represented by one genus Perhpnn, which has 
 for its synonyms Trcciiiciis, Nestra, and 8paliiiinis. The meninin 
 has its ejiilolies prolonged to an acute spine, the ennirginalion is 
 deep without tooth. 'i'h(> ligiila is narrow and truncati! ut tip, 
 tlie je.iiaghissfc sh'nd<'r and a lillle longer than tin; ligula, and 
 uniteil with the latter by a thin almost transparent mi'nd)rane, 
 which e.Meiids fruiii the l)ase of the paraglossu! to the tip of tlic 
 iignla. 
 
 The nnteiniir are rather stout beyond tiie tliird Joint, and the 
 sectnid is as long as tin' lliird. 
 
 Tlicrc is certainly no reason why Pcrirjovn. shotdd l)e placed as 
 a TrniK'atipenne. The two supra-orbital setie remove it from 
 association with the llarpalide series. Taking its inlire organi- 
 zation, it seenis better placed in the prosont tribe than anywhere 
 else.

 From the p-reat -inmber of j.?enera which have been established 
 on trivial characters, this tribe has become the most difliciilt to 
 study of any in the CarabidiC, exceptinf;: possibly the Lebiini. 
 Characters drawn from the ligida and |tai'aji|ossie have here, as 
 in tin- Lebiini, been pushed to nn extreme, and the study of them 
 from dissections proves that in both tribes they have not the great 
 value which has been assigned to them. 
 
 The tribi! llarpalini may bo divided jirimarily b\^ the tarsal 
 vestiture of the mah^ into three seiies, une of which nniy be again 
 divided, forming four groups, of which but three are repre.seiited 
 in our fauna.

 full discussion of the characters wliiuli serve to divide the speeies 
 ill siiltgeiierii uiid lower groups — the trilid anterior tibial spur, 
 the spur ijrouder ut middle and the slender spur. In two .species, 
 lid r pall liileti and ojiocuIuk, tlie first joint of the anterior tarsus of 
 the female is dilated, and in the former that joint is soniewliat 
 l>rok)ngeil under the second. 
 
 Xkstu.notus. — Anterior tarsi hroadly dilated in the male, the 
 first four joints d"nsely sponuy puheseeiit heneath, niiddh' tarsi 
 with four joints less widely dilated and sixnigy piilieseeiit Iieiieath, 
 the lirst entirely glabrous, ]tosterior tarsi slender and long. Klytra 
 with one dorsal piineturo. The liguhi is rather narrow and 
 parallel, the paraglossse broad and a little longer than it. 
 
 Comparing the dilferenees between the liguhi and parnglossa' 
 with those (tbserved in Har/iahis there does not seem any viiiid 
 reason for retaining the genus ajiart from Anisoildcli/lus, and the 
 speeies will find a suitable position between the oitKiroidn/i and 
 .svvvV'CM.s- groups of that genus. 
 
 Ami'IIasia. — Here the' eharaeters are essentially those of vhu.s'o- 
 (hnii/his .ii'ricciis. The paraglossa) are similar in form to Aniso- 
 daetylus, and merely a little longer. 
 
 l']iiiV'riuoin's — The se.xual eharaeters and those derived from 
 the posterior tarsi are jireeisely those of Jiiisoilinti/liis <miiif! 
 and l/i/iift. The paraglossiu are a little broader than in typical 
 A>iisii<l(ifti/li. 
 
 Si'oNddi'i s. — TIk! liguhi and paraglossic are intermediate in 
 strueliire between the typical Anisitiluctijlu.t and Xi'slonohis, and 
 the liguhi is free for a greater distance at tiji. Tlie sexual eiia- 
 ra(!ters are those of tlie amnraidcs group. The iiosteiior tarsi 
 lue how(!ver slender. The elytra being i)iiiietiilate and wilii a 
 single dorsal puncture, this species forms an intermediate liel-veen 
 the ilisraiili'us group and sericrK)'. 
 
 From the alxive remarks it would ap|)ear that these genera are 
 inseparablo from AniKodacli/lun. 
 
 It is worthy of note that we may have in A)ii.-<o<hi'ti/lufi more 
 than one setiii-erous piineture at each angle of the cly])eus, while 
 in most Carabidiu there is liut one, and even this may be lost.

 Sub-Family I — NOSODENDRIN.E. 
 
 Hut a single genus, Xesodondron, constitutes this sub-family. 
 It is reproseuteil in Europe by one spi'cies, and In the Atlantic 
 and Pacific regions, respectively, also by single species. It Is 
 siilficlently (llstlngulslied liy the large, elongate, scml-elllptical 
 nicnluni, entirely closing the mouth below, leaving only a very 
 narrow portion of (he maxilla; to fill liie fissurt; on cadi side; the 
 licad is advanced; (he aiitcniue ll-jointed, situated under (he 
 t-iile of the head; tiie labrum Is hullstinct; (lie tarsi not iobcd. 
 
 They are loss than one-fonr(h of an inch long, oval, convex,

 Sub-Family H.— llVllUlIIXyE. 
 
 In this sub-family the head is retracted; the mentum small, 
 (piadratc; t!ie liase of the maxilla; largely exposed ; the labrum 
 distinct; (he antenna' inserted under the sides of the head. 
 
 We would arrange these genera in three tribes: —

 In this group the nntenniu are more or less compressed, some-

 oiit appendages or siniiation ; the second joint, is short, sometimes 
 very short an<l transverse {/.inidolti). The sexes arc similar in 
 appearance, e.xce|it in one sjiecies of I'IhiHiiuh, where the elytra 
 of the 9 are short and the wings wanting. The eyes are larger 
 in % than 9, but arc separated liy a wide .'^paee both above and 
 beneath in all the species. In the S the last ventral segment is 
 small and narrow, covered i)y the scutate last oorsal, which varies 
 in form according to genus and species. Tlie light oi'gans, when 
 jne-ent, are more developed in %, than 9, which is the reverse of 
 what obtains in the group Lampyres. The head is always covered 
 liy I he hood-like prothorax. The cpiplenrm of the elytra are wide 
 at the base; the inferior (or distal) margin is reflexed, and eon- 
 verges more or less to the lateral margin of the elytra. The elytra 
 vary in color; in the species without well-developed light organs 
 they are lilaek, with the single exception of Pi/ropi/rfn iixlirla, 
 where they are brown iimrgincd witii testace(Uis, as in the brilli-

 We have excluded the singular genus Omvlhrs from this snii-

 nuitai)ly placed we do not know.

 This tribe consists of liut one genus represented in our fanim 
 by a moderate numl)er of sjw'cies. They are much more imiiicr- 
 ous in tropical America, but so far as I am aware do not (mciii 
 in other countries. Chauliognathus diflers from all others in dnr 
 fauna not only by the elongated head, and singular strurture nl 
 the maxilhiry lobe, which has a long extensile and contractile 
 fleshy filament, but also by the peculiar arrangement of the iiinicr 
 surface of the prothorax, and the sexual characters oi the %. 
 
 Trilx^ II.— TELEPnORINI. 
 
 Excluding 0)nrlhi's, ns above indicated, we have no improve- 
 ment to suggest to the table of groups already given, Classilica-

 Group I.— Podabrl. 
 
 Although tiie species of this group differ in the form of palpi, 
 as well ns in the tarsal claws, they seem to indicate but one 
 natural genus. They are more numerous in the northern part 
 of the continent, and gradually fade out towards the tropics

 the inner angle of tlu! triangular joints is freciuently prolonged 
 greatly. Finding that !.< Phyllobieniis tiie pronotnm is delined 
 by a distinet lateral line, it has been removed to the present 
 tribe, instead of constituting with it a group of tiie previous

 Piih-Trihe 2.— Coprilli (genuini). 
 
 The gradually thickened middle and hind tibia) unfit these 
 insects for transporting the balls of material which serve for tiie 
 food of the larva^ ; though some of the species ilo construct linljs, 
 they bury them in the place where they are formed. The scmuiI 
 difl'erences are frequently strongly marked, the male having horns 
 on the head or thora.x. The epii)leuric are always .larrow, ami 
 tiie first joint of the tarsi is elongated. The anterior tarsi iue 
 wauling in .some species of I'lianteus, and the claws are all want- 
 ing in the same genus. 
 
 The following groups arc represented in our fauna: — 
 
 Third joint of lahial p.nlpi distinct; 
 
 Anterior coxne very transverse, not prominent. Scatoxomi. 
 
 Anterior coxa' short, prominent ; lahial palpi dilated. ('(ii'ni.s.

 Our only representative of this group is Chooridium, containing 
 two moderately small, convex, shining, bronzed black sfjccics 
 found in dung They resemble Ilister, with finely striate clytrn. 
 The 3-jointed labial palpi, and the transverse, not prominent, 
 anterior coxaj, readily distinguish it from the other groups. The 
 claws arc small, without onyehium, but the tip of the la.st joint <>( 
 the tarsi is prolonged beneath into an obtuse i»rocess one-half as 
 long as the claws. 
 
 Group II.— Copres. 
 
 The labial pnlpi are 3-jointed, broad, and compressed ; the

 ill tulicrcies and horns on the head and thorax. The species of 
 riiauiPus arc brilliantly colored, and J', vcwnifcx, with its rougii 
 Clipper-colored tlioiax and green elytra, i.-^ familiar to every col-

 Group III. — Onthophagi. 
 
 Several species of Ontho[ihagus from the Atlantic .slope, and 
 oiii' Oiiiti(!ellus from California represent this group. 
 
 The anterior coxie ar(^ large, conical, and iirotubcraiit ; the 
 labial palpi are Imt 2-Jointed, the third joint being obsolete; the 
 tarsal elaw.s are distinct, and the onychinm is long, with the t>vo

 sides of the tiionix not eiliato with hairs, were placed hy Krieiison 
 lis a separate genus, Oniorgus; hut the characters, as observed 
 l)y Lacorduire, are indellnife, and it i.s not retained. 
 
 Tiie genus Trox possesses a distinct siridulatiiig organ ; it is 
 an elliptical plate, wilh pearly redeetions, occupying the upper 
 piirt of the external lace of the ascending imrtion of the lirsl ven- 
 tral segment, and is covered by the elylra ; on the inner surface 
 of the fdytra, near the nnirgiu, about opposite the inetatliorax, is 
 an oval, smooth, jxilislied space, which has probably some con- 
 nection with the slrididatiiig organ. 
 
 
 Sub-Family II.— MHLOLONTIIIX/E. 
 
 Tills sub-family holds an intermediate jjosition between the 
 Liiparosticti and I'leurosticti. The second pair of alxloininal spira- 
 I'ies is placed in the mendtrane connecting the ventral and dorsal 
 segiuents, as in other Hcaraba'ida;; in most species the third, and 
 souietimes the fourth, at the outer limit of lliis mend)rane; tiie lifih 
 and si.\lh pairs are in the dorsal portion of the ventral segments, 
 liut the lines connecting them do not divergi.' strongly, as in the 
 I'leurosticti; the i.'venth or last pair is usimllj' visible iiehind the 
 elytra, but variable in iiositioii ; in I'Mier species, forndng the first 
 two tribes, however, the sidracles are placed as in the Laparosticti, 
 all being in the connecting iiiembiane. 
 
 The clypeus is usually prolonged and margined in front, so that 
 the mouth is inferior, but in (Jlaphvrini the mandibles and lal)ruiii 
 are prominent; the luandibles are corneous, sliort, pyramidal: 
 the meutum large, quadrate, with the ligula usuiiily corneous ami 
 connate with the inentum, though sometimes free and membranous, 
 as in the Laparosticti; the clypeal suture is usually distinct, trans- 
 verse; the antenmc have from seven to ten joints, and the club is 
 always lamellate, sometimes consisting of six or five, hut usually 
 of three joints, and is frecpiently longer in tiie males; the tarsi 
 are iihvays perfect, r)-jointed, with tiie claws variable in form, and 
 the bisetose onycliiuin is present in nil the trilics except Iloplini, 
 
 The s])ecies feed exclusively on living ve!T(>t.,!)lo niatter, and it

 This sub-ti'ibe is also represented in our fauna by a sinfrlc 
 genus, Seriea, of universal distribution. 'I'hey are oblong, emi- 
 ve.\ insects, of a brown color, usually with iridescent rellection?-; 
 liie elytra arc indistinctly .'-uleate; the pygiiliuin is sonietinio 
 )tartly covered by the elytra. 
 
 It is readib distinguished from all others of this sub-family liy 
 the lalirum being connate with the under surlace of llie cl^ll(■u^, 
 and therel'ore indistinct. 
 
 The filih ventral segment and the ]»roi)ygidium are separated 
 by a distinct suti're, and the spiracle is placed e.\ternal to this 
 suture, half way between the anterior and posterior margin ot' 
 the ventral segment. The posterior coxie are flat, and l)ruadly 
 dilated.

 Three species of Macrodactylus, distributed from the Atlantic 
 to Arizona, alone represent this group in our fauna; they arc 
 eomnu)nly known as rose-liugs, and arc very tlestructive to roses 
 when in bloom. 'I'hey are elongate, brownish insects, densely 
 eovei'cd with ochreons scales, so as to appear udlow ; the tar.-i 
 are very long; the claws long, slender, diverging, clert al tip: 
 the fifih ventral segment and propygidiuni are connate, lorndng 
 a solid ring, and the last spiracle is placed on the suture. The 
 labrum is not connate with the cl^'iteus; tin.' nientum is narrow, 
 and channelli'fl; the anterior co.xa- arc conical and pronnneiil : 
 the ventral segments are not conmite, and the legs are slender.

 Tiie apical margin of the thora.v is never membranous ; the 
 fiflii k'entral segment is connate willi the propygidium l)y an angii-

 This group is snirK!iently distinguished by tiic labial paljji* 
 being inserted on the nniler surface of the ligula near the sides. 
 The species are glal)rons, or pubescent al)ove; the Ihora.x is ninr-

 The genera of this sub-lrilic were known only from Africa, 
 Australia, and Polynesia, until the discovery of Pliobihui Lee., 
 a Californian genus, allied, apparently, to the South African 
 'rri/fxiin Er., the characters of wliicli are very iiulelinitely made 
 known ; but, from the dilfereiiee of locality, the two genera can- 
 not be sujiposed to be identical. 
 
 The only character by which this sub-tribe is distinguished 
 from Ihe jtrcceding is that the ventral segments are not connate, 
 and the prothorax margined at apex with mcinlirane. The an- 
 terior eoxic are a little more prominent, and the side pieces of the 
 ineiathorax are equally wide. 
 
 The generic characters of I'hobetus are: nntennns '.)- or 10- 
 jointed, varying according to individuals and not species ; with

 labrnm transverse, concav(>, somewhat enmrginate; prothorax

 This tribe, anion}? its forcijjin nienihcrs, numbers the largest 
 (Joieoptera existing; some of the genera arc remarkable for the 
 size and form of horns on the thorax and lieatl of the males. 
 
 Organs of strididalion are found in many geiKira; they consist 
 of rugose spaces, usually on the propygidium, Monn;ti? e» on the 
 inner surface of the elytra. 'I'lie lifth ventral segment and the

 But two genera of this sub-tribe exist in our fauna; they have 
 tlic appearance of Meloloishinm, and are readily distinguisheil 
 from the following sub-tribes by the thorax and head beinij; 
 entirely destitute of tulterdes, and by the clypeus being Hat, 
 parabolic, and linely nmrgined; tin- mandibles project but slightly, 
 and are not toothed externally. The males have the lifth joint of 
 the anterior tarsi much enlarged, and the club of the antenna; is 
 sometimes longer than in the f.-male. Stridulating organs none; 
 posterior tibia; not festooned nor expanded at tip; mentuin trun- 
 cate in front; antenna' 10-jointed (!)-jointcd only in certain species 
 of Cydoeephala) ; the thorax is oidy partially nmrgined at the 
 base ; the prosternuin is prominent behind the coxa; ; the tarsi 
 are cylindrical. 
 
 Our two genera have the mcRo.sternun» scarcely visible between

 Tiie insects of this sub-tribe vary much in .size and form, l)Ut 
 (iiive the following eliarueler.s in eommoii: — 
 
 Labial palpi iniserted at the .sides of the mcnluin; nnuidil)les 
 ItroMiinent, usually toothed externally; head more or less tuber- 
 culate (exeept in Strategus), always with some elevations, some- 
 times armed with a horn; tiiorux usually tubcreulate or horned; 
 ■Ulterior feet not elongate in the nudes; clypeus not parabolie, 
 liiit rather triangular, redexed with one or two small apieal teeth; 
 iiientum narrowed in front; posterior tibiu) expanded at the e.»- 
 ireinity, sometimes digitate; first joint of hind tarsi more or less 
 elevated at its upper extremity. Slridulating organs are fouiid 
 exeept in Aphonns. 
 
 The sexual characters arc usually in the greater development 
 of horns or tubercles in the male, rarely (Liyi/rua relicluH) in 
 the thiekening of the outer elaw of the anterior tarsi. 
 
 Two groups are represented : —

 Moderate-sized, robust, convex sjieeies, having the head slightly 
 lubereulate, or rather, in our species, with small anterior ridges 
 or teeth, alike in both sexes; thorax sometimes with a small acute 
 tnberele near the anterior margin, sometimes entirely uniform, 
 convex. 
 
 Three genera occur in our fauna: Ligyrus, generally diffused; 
 Aphonus, from the Atlantic and Central districts.

 extends into New Mexico. It greatly resembles in appearance 
 Aphonus clunalin.

 In the iiiiijority of {genera the iiiandiblcs are feebly dcvchiped,

 A fjrciit fi'inily, containing an imnioiisc number of spocios, 
 wiiicli livo in the hirval state exclusively on the woody parts of 
 plants. 'I'lie species are remarkable for lar<r<^ size, beauty of 
 <'olf)r, or elejjancf of form, and iiave been, on these accounts, 
 frreat favorites with collectors. Nevertheless tiieir classifieation. 
 and even, tla; deliiiition of tlie family, present <liirieulties which 
 have been called insuperable by every systematist who lias yet 
 attempted the task. 
 
 'I'he species are easily recognized, the chief variations being 
 only tiiose of size, dependent probal)ly on tiic cpnuitity of food 
 ol)tained l)y the larva, or the e.vcellenee of its digestive power. 
 At any rate, the differences appear to be individual and not in- 
 dicative of races. The genera are, on the other hand, extremely 
 indistinct, as at present defined, for the reason that the species 
 IVecpiently differ not only by the usual specific characters of form, 
 color, sculiiture, etc., I)nt by structural peculiarities of consider- 
 able nu)nierit, sometimes sexual, soinetiincs asexual. Hy reganl- 
 ing these peculiarities as of generic value, tiic number of genera 
 (as in birds) has been vastly and unnecessarily increased, and 
 the system of classiticaticni correspondingly diluted, so that the 
 nnu-e es.seiitial points of resemldance l)etwecpi allied forms are 
 lost sight of, .and the arrangement becomes (piite artificial. 
 Frecpicnt reference will ite niaile in the following pages to the 
 misplacement of genera by the best authorities ; and, also, what 
 tends to greater confusion, to errors of description in several 
 of our genera, which lead to an incorrect appreciation of their 
 relations.

 Several clinrnctcrs which have been recently adopteil for the

 illusory iiiiportuncc; and ani(in<r these, the extension outwards 
 of tlie middle coxu;, so that they attain or not the episterna, is 
 one of the most indefinite, and we have, therefore, rejected it as 
 fur as possible in the following scheme. 
 
 We have, in. common with previous investipitors, failed tiius 
 fur to find any distinct diirerence capable of expression in words 
 iictweeii this i'anuly and Chrysomelidie. One fanuliar with the

 a slijrlit approximation to it seems to be nni.de in the fact, tiiuL

 iiielatliorax to extend to the sides of tlie ventral se.nnieiits, wliile

 liioiigh lUMM'ssariiy more rect'iit, type, whicii could have existed 
 (inly siiiire tin; developnu^nt of the higher broad-leaved plants. 
 
 And in continuation of this same subject, we would rcl'er the 
 liilliciilties of classilicalion of the Loiigicoriis to the fact, that 
 being exclusively feeders upon woody tissue, and passing a very 
 long period in tiic larval state, in tin- inierior of tniMl;.^ or 
 hranches of trees, protected against inundations iiy the buoyancy 
 of their juvenile homes, they have been peculiarly (pialilied, not

 every species has structural peculiarities for its specific ehiirnc-

 Sub-Family I.— PRIONINyE. 
 
 The insects of this sub-family are generally of hirge size, con-

 or black, and the elytra usually coriaceous in ajipearance, becom- 
 ing metallic iim! of lirnier consistence in some of tiie geiieni 
 with finely granulated eyes. The labrum is connate with tin" 
 epistoma. Tiio ligula is always entirely < orneous. without di;-- 
 tinct paragiosssB ; the supports of the labial \k\\\)'\ are conmiie 
 with liie ligula. The mandil)les are strong, frcciucntiy elongated 
 in the males, and are destitute of menibram! or iiiohir tootii. The 
 lobes of tiie iiiaxillic are small, the inner one obsolete, and tiie 
 hist joint of the palpi is trinngiilar. TIk; antenna' are fiiriiishcd 
 with poriferous spaci's, varying iiceording to the genus and tribe. 
 The prothorax is always distinctly margined, the front coxie iii'e 
 transverse, with distinct trochantin. 
 
 The mesonotum never has stridulating surfaces, such as are

 One species, Ergatcx spiculalKx Lee. of large size (i^h-Cul mm. 
 loiifi). is not uncommon on the maritime; I'acilic slo)ie iind in New 
 Mexico. The tribe is easily known liy the prothorax l)eing much 
 liroiider in the male than in the female, and finely puiiclnred; 
 ill the latter se.\ the sculpture is very course, and the small leelh 
 of the lateral margin longer and more acute. The head is small, 
 the eyes rcniform and coarsely granulated. ; ipitenna' II -jointed, 
 slender, two-thirds the length of the body in tin' %, aliout half 
 the length of the body in the ?, rough with elevated punctures, 
 with the od joint as long as the three following united ; jioril- 
 erons .spaces on tin; lUl joint small iiieoiispicuoiis, on the under 
 surface near the distal end, gradually becoming larger, until the 
 outer joints beiMiinc I'litirely ))iiriferous, and irregularly reticulated 
 with line elevated lines forming elongate cells, which are much 
 less distinct, ami in fact hardly to be seen n the male. 
 
 '!"he generic characters are not suniciently distinct from the 
 JMiropean species K. falwr to warrant the retention of the genus 
 Tricliociiemiii proposed in the earliest description of this insect. 
 
 Trill. II.— :tiAM>ono\Ti:vi. 
 
 This tribe contains also species of very large size (one from 
 Florida is before us that is 61 mm. long), with the aides of the 
 
 * Canadian Kntoniolo^ist, iv. 139.

 with tlio last joint, triangular. The other eharauters are alinni- 
 inal, the nl)doinen in tliu 9 lieing del'ornn'd in the group Ohrin. 
 and tlie elytra more or less suliulate or uhhrcvialed in Stenopteri; 
 th(! eyes are (inely frranulaled in the latter, variable in the loriMcr, 
 
 The ndinities of this trilie lead from the last groups of Ceiiun- 
 byeini, towards the triiies with finely granulated eyes, Leptmini 
 on the one side, and Callidiini (ui the <ither. 
 
 (iiciiiii I. — Obria. 
 
 This group contains a few small species in which the gramilii- 
 tion of the eyes lias ceased to be of primary importance; Imi 
 which is easily distinguished by the 1st, segment, of the abdoMiiii 
 being very long, and the iJd and following irregular, hairy, ex- 
 cavated or dofornu'd in the 9. 
 
 The mandibles are small and acute, the anlenmc slender, 
 .long as, or shortei' than, the body; the palpi are unecpial, ami iIm 
 last joint is rarely dilated. The anlennai arc slender, and tin 
 2d joint is larger than in genuine Cevainbycini, The prothoiii.x 
 is variable in form, always, however, constricted and pcdniirii 
 lated at base, and mirrower than the elytra; the front coxa' an 
 conical, prominent, contiguous, cavities small, roinnled or anun 
 lated, closed beliintl; middle coxal cavities not open externally 
 The thighs are strongly elavate, the tibial spurs small or modi' 
 rate, and the Isl joint of the hind tarsi is as long as the lw( 
 following. 
 
 It is worthy of remark that in Obrium the structuri! of the eye< 
 has merely Hpocilic signilieanee ; in our (>. ruhnnn the eyes iiiv 
 very coarsely granulated, while in the nearly allied Kuropeaa 0. 
 briiiini'um the lenses are much smaller.

 We have adopteil the iianie of this triiie from Laeordairc; it has 
 two re[)resenlatives in our fauna; four species of Pteroplanis 
 from Florida, Texas, New Mexico, and Arizona, and lloloi)ieura, 
 found in California. 
 
 The head is niodi'rate, niandii)les small, acute, curved ; the eyes 
 large, very deeply emarninate, not very fine'y {rranniated, and 
 eiubraeing the base of the antennae rather less than usual, the 
 upper lolie is hirircr than usual; the front is i,;Hi; r liat, with

 joint cylindrical, truiieate .'it tip; the iiienluiii is trapezoidal, ami 
 more porrect than in lu'iji'hboriiiir g'roiips, beiii!; almost as in 
 Callidium; the antenna) Ci?) are a little more than half as long as 
 the body, stout, serrate, and velvety; the 1st joint is ns huig as 
 the ;id. but stouter, the 'id is oiie-lhird the size of the JJ<1, the 4th 
 shorter than the 5th, which is the longest, the following diminish 
 in leiiglii. The jirothorax is rounded on the sides, truncate in 
 front, bi>iiiuate at base; scutelluni variable in form; elytra a little 
 wider from the base, rounded at tip, with the suture, margin, and 
 three iliseoidal eosta^ elevated, the intermediate costa liciiig the 
 longest; epiplenrtu well marked, extending to the lip. l*ro- 
 steriiiiin narrow between the co.xa', which are rounded, wilh the 
 cavities open behind, and feebly angulaled externally; nieso- 
 sternuni Hat, triangular, co.xal cavities widely open externally; 
 opiniera of inetathorax moderately wide, |)arallel. Ventral .seg- 
 ments nearly ecpial. Legs short, slender, thighs not elavate, 
 tibial spurs very .small, 1st joint of hind tar.si as long as the two 
 following. The stridniating plate is very finely striate, large 
 and undivided, with a row of pnnetures each side. On each side 
 of the lU'onotum there is an elliptical depressed space, ttderably 
 well delined by an acute edge. 
 
 This like the following tribe is n transition form; the 2d joint 
 of the anienme is too large for the series in which we have ]>lace(l

 tliorax constricted at base and ape.v, with an acute lateral spine 
 tach side, and two acute dorsal tubercles; prosterniini rather 
 iiroad, co.xal cavities strongly angiilated, widely open behind; 
 iiicsostcrnuni broad, truiuate behind, declivous ".i front; epimera 
 very large, extending to the co.xal cavities; nietasterniiiu not 
 acutely einargiiuite behind, episterna ratlier wide, narrowed 
 licliind, and nearly jtointed ; intercoxal process of 1st ventral 
 hroadly rounded in front, segments lu'arly ecpial in length, oth 
 tiiiiicale at tip, with an acute, short, medial cleft in 9; shorter,

 Oiiuii) II — Tracbyderes. 
 
 Insects of large size, and glabrous surface, having the antemiie 
 compressed, much longer than the body in 1, with vcit distincl 
 poiiferons system, 11th joint either simple or npi)endi(uiate; the 
 mandibles of Dendrobias % are very long, and have an acute 
 tooth near the tip, so as to appear en)arginate, without really 
 being so. The palpi June the last joint cylintlrical, and deeply 
 foveate. 'I"he seutellum is very large, acutely triangular; nieso- 
 notum with narrow stridulating plate. Klytra convex, iiairowcd 
 from the base, rounded at tip. I'rothorax variable in form, tuber- 
 culate on the disk, and strdugly armed on the sides in Demlro- 
 bias, uniformly convex in Li.ssonotus; prosternum peri)endicu- 
 hirly declivous in both, armed also with a large tubercle in front 
 of iheeo.xa; in Dendrobias; mesosternnm elevated, perpendieular 
 in front ; side pieces of metaslernum toleraldy wide, mirrower

 on more extended observation, the group ats here defined contains 
 ill! those genera in our fauna in which the eyes are finely granu- 
 iaii'il, di^eply emarginate, with the upper lobe wide; the scuteiluin 
 acute, 1ml not very large, though sometimes elongate; and the 
 impthorax not distinctly lohed, but only feebly bisimmte or trun- 
 cate at base. The antenuiU are more slender than in Trachyderes, 
 and the poriferous system is much less di.->tinet, or even obsolete, 
 tiioiigh in Stenaspis it is still quite obvious, and the joints are 
 ciuinate and bisulcate. In IJatyle the last joint of the })alpi 
 ( wlii('li is sui)eylindrieal and truncate) is very feebly impressed. 
 
 'file antenna! tubercles are either much elevated, leaving a 
 concavity between them, or scarcely elevated, in which case the 
 vertex is nearly flat; the front in the former is very large, sipiare,

 cles are less eli^vated, the front is moderate, declivous, and the

 l)ut ii(i( named by Laeordaire. * 
 
 Of tiie genera lalniiated above Stenaspis and Tragidion oecm' 
 from the Athmlie to tiie Tacide in tiie warmer regions, tiie fornur 
 extending nortliward in tiie central region, tlic latter in ilic 
 Athmtie distriet. Purpurieenns oeeurs in tiie middle and 
 Western States. Tlie next three genera art round in Tcxiis, 
 and Hatyle oeeurs in the AlJanlie region es|ieeialiy Houthward. 
 
 The genus last named is placed by Ijacordiiire in Ileteropsidi s, 
 of wliicli he observes that tiie middle coxal cavities ai'c cloed 
 externally; we lind, however, in our Rpccimens that the uiesotlii- 
 raci(! epiniera attain the coxal cavities, and that they are as open 
 as in rnrpnricenus. 'I'he character as used by Laecu'daire seems 
 very deceptive, and without value for svstematie results.

 (,Mosely related to tin? i)receding, and oidy dillVring in fact liy 
 the mandibles not being acute at tip, but truncate, forming a 
 chisel-shaped Cflge, which is emarginate. The front is modenite 
 in size, nearly perpendicular, and the aniermal tubercles are iii>t 
 much elevaled ; the genie are not elongated. The s(;utellmM i-; 
 small, acutely triangular, and the slridiihiling plate of the nic.-d- 
 notuin is large. The side pieces of the nielastcrnum are tolciM- 
 bly wide, not narrowed b .lind, aiul the scent |)ores are distinct, 
 except in I'crdiihriiti rilttiliit^ and Sphit nolheciif: fiiritlnlufi. Tlic 
 legs are sleeder, thighs not clavate, tibia! spurs rather long, hind 
 tarsi with the 1st joint etpial to the two following; less slcmli r 
 in Tylosis and Crossidius than in the other genera. The antcnii;e 
 are slender, with elongate sensitive spaces nenr the carina of lln' 
 under nnirgin. The last joint of the palpi is subcylindrical, and 
 ini|tressed, as usual, in the otluM' groups of this trilx". 
 
 Our genera, which arc found mostly in Texas, Arizona, iiml

 This tribe is represented in our fauiui by Xrti/dali.-i )iifllilii.-< 
 Say in the Atlantic, two species of tiic same genus, and Ulorhitli.^ 
 Icoiiinus in the I'ucilic States. '\'\\v hitter is a large, robust, ami 
 very hairy in.sect, which is well figured in the Tacilic JM! 
 Explorations, vol. xi. pi. 2, f. 12. 
 
 Tiie undivided .sfridulating plate is an exception in the Lepiii- 
 roid series, to which we liuve attached this remarkable tribe, aini 
 with which it has very strong relations. It would perhaps hi' 
 l)rtter to view it as representing a separate series, in which mi^'ln 
 be placed various foreign tribes in which the wings are not folilr i

 wings arc not foUlei 
 
 at the end. In this connection, it is important to observe that 
 in Stenopternrt and Molorciins, which have abbreviated elytra, 
 the wings are not straight, but folded in the usual inannei'. 
 
 Although the under surface of the head is linuted each side by 
 a line, as in other licpturoides, tlic line is less defined and tiie 
 nientigcrous process is not more developed than in Cerauil)y('oi(l(!s, 
 and the ineutuin has the short transverse form so frequent in that 
 .-^'■ries, and totally unlike the ordinary Leptura type.

 witli a smiill but ilisiinet eamrgiimtioii iii Eiieyelops, feebly eiiiiu'- 
 {riiiate ill Leptalia. 
 
 Tiie genera may be thus distinguished: 
 
 Tarsi wider, joiiit.s l-l! lirush-likf bi'iioath. Pyrotrichus. 
 
 Tarsi sli'iuU^r, 1st ji)iiit vovy loiii,'; 
 
 llinil tarsi with liasal joint sukato, bnisli-likc! at tlio sides. Leptalia. 
 
 Hind tarsi with basal joint cylindrical. Encyciopa 
 
 The dKrercnee.s in the tarsi are .similar to those observed in 
 the three groups of Lepturini. J'yrotriehns being similar to 
 Khagiiim, Leptalia to the Toxotus group, and Kiu'yelops to the 
 genuine Leplune. 
 
 To Leptalia belongs Anoplodfra macileiita ^fann., a black 
 speeie.s from Alaska; A. Krankenlneiiseri jlliinn. is a variety wiili 
 striped elytra and yellow legs; Leptura f'useieollis Lfc. is a 
 larger variety from Vaneonver ami Calirortiia, in wliieh the elyiia 
 are also striped, and the legs yelhtw, sometimes varied with black. 
 The reference to Anoplodera was .-;ngiihirly iiia|ipropriate, since 
 the sides of the prothorax are armed with a rather acute tubercU', 
 aUuost as iii Centrodera. 
 
 Tribe xviii.- li:pti;rixi. 
 
 The numerous species composing this tribe are easily recog- 
 nized by the pronniieiil conical front coxa', with the cavities 
 augnlated externally, open, somelimes almost closed Ijchind ; 
 middle coxal cavities widely open externally; the palpi are 
 always unctpial, the imixillary elongated, the last joint cylindriciil, 
 (M- triangular, impressed. Tiie head is variabh' in form, cither 
 gradually narrowed behind the eyes, or suddenly and stronglv 
 constrii'ted, in either cas(' the neck is long; the fnuit is slighilv 
 declivous, and the antcnmu arc inserted well in front of the eyes 
 or slightly between thciu ; the eyes are oval, longitudinal, or 
 slightly obli(pic, entire or einarginated. Tin' imindil)lcs are (hit, 
 acute, and fringed on the inner margin. 'I'he liyposloma is 
 defim-d ijy very distinct lateral lines, the meutigeroii.s process i- 
 very distim;t, iind the nientuni Hat and trapezoidal. The other 
 characters are varial)le, tin; anteniue are usually slender, S(nne- 
 times snbscrratc; the prothorax is usually wider at base, soiiie- 
 tiiuos tuberculntcd at the sides; the elytra usually narrowed from

 is oc'uasionaily ul)soiit, but tiio oliiur two will then, witii tlic 
 gcniTal ai>|)C'anuu'i' of tin- in.st'cl, make its utrmities unniislukablr. 
 To tlio first cluiractcr tiiere is no exception in onr fauini, and unly 
 the Tniesislernus },'n)np of tlie oilier conlinenl; Mi(;hthysuiii;i, 
 haviui,^ the last joint of the palpi triangular, is the only exceptinn 
 in North America to the second character; the third ciiaracter is 
 lost in some genera of low organization, sucii as Methia, Dyspluig;!, 
 etc., which arc only feebly dilferentiated from the Oeme group ot' 
 
 /'eraniovcinic. 
 
 'I'hu front is vertical, usually largo and flat, rarely shorter 
 convex; the <'yes are usually finely or moderately linely grai 
 
 :iiiil 
 
 Ill- 
 
 luted, rarely (piite coarsely granulated; eniargiiiuted, freipieiiily 
 divided, sometinies (Spalacopsis) with the upper loi)e wanting. ■' 
 The front, coxie are rounded, never transverse, the coxal fissure is 
 frequently open, so that tlie cavity becomes angiilated, liul this 
 character, as in Ceranibyeidic, is not of great importance; tluy 
 are closed behind in nearly all, widely open in Methiini, with a 
 tendency to become open in Monohaininini. 'I"he middle co.va' 
 are eiilirely closed iiy the sternal pieces in the liigher forms of 
 each series, ojien to the side pieces in the others, but this ciiaracter 
 
 is al 
 
 so oi small iinportanee. 
 
 'i'lie metasteriiiini never has scent 
 
 glands; and the stridiilating plate of the iiiesonotiim is always 
 undivided, Ihoiigh freipiently narrow. The ventral segments iiic 
 always ,5, and present no remarkable chanieters. The legs are 
 usually short, sometimes (Moiiohammus 1, Doreaschema) long: 
 
 middle til 
 
 with a tubercle or sinus on the outer face in nio>t 
 
 genera ; tibial spurs short ; iingiK s either ilivurictitr (exieiidiiej 
 in a iiliine at- right aiigh's to the length of the last joint), or <// 
 
 vcrijciil. (not in the 
 
 plane, but forming an angle). Tli 
 
 character, first oliserved iiy liiicordaire, seems to lie of great 
 value: in the true Ceramltycidic the daws do not appear to vary 
 to the same extent, but to be slightly movable in nearly all, if 
 not all, the spijcies.

 Tiiis tribe lias been established on the very anomalona Mich- 
 tln/f'innd /iftcrotln.ruin Lee., of wliieh a single specimen has iieen 
 found in the upper part of (Jcorgia. The head is rather large, 
 tiie front short, scarcely vertical, the siipiiort of laiirnni visible, 
 coriaceous, labrnni snnill, rounded in from. Palpi very niuqnal, 
 with the last joint securiform. Antennio slender, as long as the 
 body, scape rather slotit, as long as the Jjd joint, rounded at tip, 
 without cicatrix ; od joint not longer than 4tli ; eyes small elon- 
 gate, coarsely granulated, lower lobe narrow. I'mlluirax as wide 
 as the head, with an acute lateral spine, rather in front of the 
 middle. l-'Jylra elongate not wider than prothorax. Inlercoxal 
 process of iirst ventral segment acute. 
 
 l''ront coxal cavities angnlated, closed behind; middle ones 
 migulated, closed externally; thighs strongly clavate, IVont tibiic 
 curved inwards and feebly suleate, nuddle ones absolutely without 
 tidiercle, sinus, or Inft of hair on the outer margin; tarsi less 
 dilated than usual, 1st joint of hind pair (Mpial to two following 
 united; last joint moderate, claws divarii'ato. 
 
 The form of llie palpi seems to show an affiidty with tlie 
 African genus I'hantasis, lint the body is much more elongate, 
 and the other chiiracters do not agree. The head and prothorax 
 are densely jinnctured and o])a(pie, the elytra nmro shining, less 
 donsely punctureil, with hairs proceeding from the punctures.

 Tiie above remarks, it may be needless to say, are ap|)licablc 
 to the genera of our fauna only. These are known as follows: — 
 
 Lateral .spine of tliorax vory prominent, tlie disk tuberculate, antemiiu 
 imich longer than the body. Lagocbirus. 
 
 Lateral spine nlituse, disk not tubercnlate, aiitennie not longer than tlie 
 hiidy in either sex. CcenopcBUS. 
 
 In the males of both genera the sixtli joint of the antennai is 
 ]irolongecl inwards and with a brnsh of hairs in Lntjochirxs, which 
 lias also the anterior tarsi dilated and liinbriate, ami the same 
 tibia fimbriate within near the tip. 
 
 Ca'uopivioi is fouiuled on Lrptoftylua Palmeri Lee. 
 
 Oronp II. — Liopi. 
 
 From the Lagoehiri this grou]) dilfers in having the thorax 
 angnlate, if tit all, behiml the middle iuul the tarsi slender. 
 
 The lateral Inlurcle of the thorax, its observed by Dr. LeCoiite, 
 varies in position from sni)-median to sub-basal. 
 
 The table of the genera of this tribe, as deliiied by Dr. LoConto 
 in the first edition of this work, requires some nniditleatioii by 
 the omission of Loidiopcenm : and Stenudins, and the introdiie- 
 tion of M<'(()frtarU(.'< (Kntessns /vcc ). 
 
 The species jilaecd provisioiiiiUy in T,opliop{riini seems rather a 
 I'ligDinicheriis allied to /'. orfijoniin, but with the lateral spine of 
 (he thorax as strong as in /'. (■riiiih(s. 
 
 Slcrnidiitit is tlie ecpiivalent of T,io])us, and those species for- 
 merly tinder the latter name are added to Leptiirgcs. 
 
 Mii'ohioiiiis Dates (luitessus Lrc), is adiled from the next 
 group, in which it Lad liecii doubtfully placed liy Dr. Let-onte, 
 he knowing the males only, while thi' description by Mr. Hates, 
 iniblislied but a few months before, liad not yet reached this 
 
 Collllll'v. 
 
 Jh'ctrii is also added to the group as its cliaractcrs do not 
 warrant a wider separation.

 arc only a little longer or .shorter than the body, the outer joints 
 prailually shorter ; the eyes are moderately or very coarsely 
 uM'anulated (Kupogonius) ; the frout coxal cavities are angulated 
 ixternally, completely closed behind; the midille ones are angu- 
 laU'd, but not open e.vternally ; the legs are siiort, thighs strongly 
 ilavate in some genera, but not so in Kupogonius and Lypsimena;

 'I he genera of this tribe are dispersed by Laconlaire among his 
 groups, Kstolides, Apoda.syitles, and I'ogonocherides ; with the 
 exception of lloplosia, which resendiles a Graphisurus, but with

 Tribt. XIV,— SAPKRDi:*'!. 
 
 Insects of cylindrical form, of larjre or medium size, with large, 
 lliit, (luadrate, vertical front, coriai.-eous Jabral support, and finely 
 granulated, deeply cniarginate eyes. The \m\\)\ are less slemler 
 than in the Acanlhoilcroid .-cries, the last joint more or less oval, 
 truncate at tip. 'i'lie antenme nvv as long as the body, or a little 
 sliortcr; the scape is m-ariy cylindrical, a little shorter than the 
 3il Joint, without ai)icai cicatrix; the outer joints scarcely diminish 
 in length. The protliorax is cylindrical, entirely umirined, and 
 without tubercles; the elytra are wider than the protliorax, 
 cylindrical, u.-^ually rounded at tip, rarely {laliarutu) the suture 
 is armed with a spine, or {ohliijiia) tin; tip is attenuated and acu- 
 minate. 
 
 The front eoXiP are angnhited externally with distinct trochant in, 
 and closed liehiiiil; ihe middle coxal cavities are angnhited, iii)en 
 externally, with disiiiict trocliantin. The prosti'rnnm is very 
 iini'i'ovv between tin coxa;, and the mesosternni.i acute behind. 
 Tlu' >id(! pieces of tl'e nietaslernuiu .ire very broad in front, and 
 II irrnwed behind ; a cliaracter not seen iu the preceding tribes. 
 The vi'utral segments are nearly etpial, the oth somewhat longer, 
 S'lniewhat truncate (?) or emai'ginale Cii). Legs moderate, 
 marly e(|ual, thighs not elavate, middle tibiie without tubercle 
 ui- sinus; iiind tarsi with 1st joint imt much elongated; last joint 
 rullier sliiM''. in general, claws divaricate; the inner one of the 
 IViint and middle ])air in the % of most of our species armed with 
 a nmnded lobe or tooth, which is wanting in S. moeala, and con- 
 Coliii; iiiid in the Ktiropean species. 
 
 The genus Saperda alone is represented in our fauna. Thus 
 far, none iiav(> been found on the I'aeilie slojjc, except .S. moc.tla, 
 11 nortiiern species, which extends from Canada to Oregon. 
 
 Some of the species are very destructive to cnltivnted trees, 
 '"'ring into the wood, or destroying the subcortical tissues of ilie 
 roots.

 Klytra usually covering the dorsal segments, sometimes 
 leaving the pygidium exposed (Camptosomes); rarelv (in 
 some genera of Gallerucini) smaller, and not covering the 
 greatly cidargcd female abdomen; epipleurui usually dis- 
 tinct. 
 
 Abdomen with five ventral segments, varying in pro- 
 portion. 
 
 Anterior coxai varying in form and position ; miildle coxio 
 either contiguous or separate; hind coxaj transverse, con- 
 tiguous, or separated, not laminate. 
 
 Legs usually short, hind thighs frequently enlarged, and 
 in some groups of Gallerucini saltatorial; tibiie never serrate, 
 usiudly without spurs; tarsi with the joints l-o usually 
 hroad, covere<l beneath with a brush ol' hair; 3d frecpiently 
 bilobed; 4th anchylosed closely to the oth, which has two 
 e(pial claws of variable form. Rarely (ILemonia, and Ste- 
 iiopodius) the tarsi arc n;irivw, and the last joint is very long, 
 with large simi)le claws, suited to grasp subaquatic plants 
 on which they li"e. 
 
 Tills family is nn immense complex, developed to llie largest 
 cxt( lit in tiie tropics, tlioiiftli by no means wiilioiil a rispi'etable 
 i'e|)res<'ntation in temperate and boreal regions. As tlie faiiction 
 of the Ceramhyeidaj is to hold the vegetable world in eiieek by 
 destroying woody fibre, the IJrueliidie ell'ect a similar result by 
 attacking the seeds, and the Clirysomeiida3 b)^ destroying tiic 
 leaver.. As the cellular and siieenleiit leaved plants have sne- 
 ct'cdod tlie drier and more iigneons forms of early geolngicai time, 
 so have the C'iirys(jineli(he jiroliably attained their higliest devel- 
 opi'ient in the more recent periods, and it is therefore interesting 
 to note that their relations witli lviiyneho|)liora are pro])ortion- 
 ntdy more feeble than those of the otiier two families above men- 
 tinned. 
 
 Among the species of this family are to be found some of the 
 most formidable Coleopterous pests of Agriculture; but with few 
 cxeeptions tiiey belong to the triiie Oallerueini. A notable ex- 
 ception, however, is the Dorijphora decemlineata, the world- 
 known Colorado potato-bug. 
 
 In order to make the tables of frii)es and genera more intelli- 
 pilile to the stu<h'nt, it will be jjroper to define the diifereiit forms 
 i)f tarsal claws, which have been used in the classilication of this 
 very troublesome family.

 Dr. Cliapuis states (Oi'n. Col. LiiconlaiiT, .\. :]"")) tliat tlio iM

 liilolit'd in all of our spcjius, including L. trcniu'u, wliii'li is 
 coninn)n to Ixith continents. 
 
 Tlicre lias been an ohjcction, wliieii we think is ill fonndcil, an 
 the part ol' several l^urojiean sysleniatists, to reeeiving liie Moiili 
 Anieriean speeies, placed by Mr. \V. V. Rogers (I'roe. Acad. Mat. 
 Sei., iSod, ;i(t), in JJufi/plmru. The speeies of Jhtri/jiliord iiic 
 eiiinnionly ciniceived to be tropical '"'isects, in which the nicsd- 
 sierni'in is more or less produced forwards. Thi.-< character, a.- 
 we know in Aniutuihi of ti.o Searabseidie, has small sij-nilieance, 
 and we would liierelbre |)refer, in onr desire to avoid unnecessaiy 
 n\Mlliplicalion of genera, to regard in this family and trilie, ihr 
 palpi as of more < .Misetinence than the niesoslernnni tor the deli- 
 nition of genera. We do this with the less relnciance, becan.-c 
 we do not observe in our si)ccies any particular transition between 
 tiie two sets of forms to wliieii we ascribe the generic names above 
 given.

 Tiie species of this tribe are very nuiuerons, and soiiietlnies 
 ill eonseipieiicc of great variation of color and sculpture, tjuite

 especially in the tropics, where tlii'y ae(iuire a splendor unknown 
 ill the temperate zones. 
 
 The trilie is well deliiied by the insertion of the auteiiiuv, which 
 in our genera are placed upon the front, let ween the eyes; they 
 are usually approxiiuate, and the front is generally carinale, with 
 I narrow ridge. The eyes are not eiuarginate and linely granu- 
 lated. Head exposi'd, and itrotli(ua.\ truncate or eiiiar,i.',iiiate in

 Tlic species of this sub-fimiily are ilislinj^iiisiied by the miihllr 
 eoxie l)eiiijr entirely ineiosed hy the sleriia, witiioiil any troehaiitin ; 
 the side pieees of tiie iiiesotliorax eoiisequeiitly do not extend in 
 the eoxal cavities; the ventral seynieiits are entirely corneons. the 
 .'Jd and 4tii luiving no vesti^'e of a posterior coriaceous nnnyin. 
 JJesides these two distinji-ni.sliing characiers, eoninion to all ilic 
 triljes, there aro others worthy of notice, wldeli belong to indi- 
 vidual tribes, and are not found to recur in the other two suli- 
 fauiilies. 
 
 The species, with the exception of Kpitrapini and a few 'rhiiin. 
 liatini, are aplemus, and the nielasternuni is very short, exeeiii 
 in the winged sjiecies. In Zopherini the eyes are very linelv 
 granulated, a singular exception in this family. The nientum i- 
 IVe(|uently very large, so as to hll entirely the gular eaviiy, and 
 to cover completely the maxilhe and ligula, so that the gular pm- 
 cess usually suppiu'ting it ceases to exist. This character recur- 
 again only in certain Asidini of the next sid)-fandly. The tm-i 
 are sonietinies sjiinous, soiuet lines pubesceul beneath. The Inmi 
 is frequently trilobed.

 Tribe IV.— TE\EBUIO:Vll\I. 
 
 Body moderately elongated, apterous, or winged ; head pro- 
 longed, but scarcely narrowed behind, not received in the iIkmm.x 
 as far as the 'ves, which are transverse and eniarginate, inode- 
 ratelv" linely granulated; front dilated on the sides, covering the 
 base of the mandil)les; epislonni truncate or sliglilly euiarginiile. 
 Tiot separated from the labruni by a <'lypeus; antenna" 1 l-jointed, 
 gradiniily thickened externally ; nieniuni small, jiartly concealing 
 the ligida, inserted upon a giilar iiciluncle; elytra embracing 
 'cebly the flanks of the aiidonien; epipleurie narrow. Anterinr 
 (roxa^ gloi)os(! ; middle coxa' with distinct trochantin; legs long; 
 tibial spurs small; tarsi idolhed beneath with silky, golden jiulic- 
 <'ence, oj- with ordinary coajse puliescenee. lliiid nuirgin of third 
 and fonrlh ventral segments subcoriaceous. 
 
 This tribe (;nd)races the ('(elonietopides of Tiacordaire, with ii 
 portion of liis Tenebrionides; the vesliture of the tarsi appears 
 to l)e of more siruclural iniporlaMce than the length of the imia- 
 sicrnuin, liy which merely apterous and winged species are (li>- 
 tinguished. The allinity pointed out between sonn- of the genei'a 
 and the trii>e Scaurini is very strong, and I'olypleuru.s might lie 
 e(|ually rtell placed in the pret'cding tribe. 
 
 The gem'a may lie divided into two groups: — 
 
 T.irsi silky pulMsci'iit ln'iiratli. I'rrs. 
 
 Tarsi cciarsi'ly inilicscrnt lii.'iicatii. Tn.vKmuoM.s. 
 
 (ir(m|) I. — Upes. 
 
 In this group the hind coxa' vary in position; the metnstcrnuni 
 in the apterous species is very short, iiut in the winged ones long: 
 the epipleurai do not reach the tip of the elytra in nmst of the 
 genera, aiul in otinn's they are gradually narrowed, reaching the 
 tip. 
 
 The spreips are found uiuler bark of dead trees. Our genera

 Tills tribe consists of the genus Cononotus, of wliicli three 
 ^liceies are fduiid under .stones in California; they are shsuder, 
 |i;de brown, linely pu'iest-ent insects of small size, having the 
 tlior.'ix elongated, and regularly conical in form, and n>iich Jiar-

 cnpable of being Iriiced ; the maxillary palpi are very long, and 
 !lii' last jninl is large and triangular. 
 
 It is very dilllcuh to indicate the allinities of this genus; it 
 seems to lie ecpndly out of place in any family. It was formerly 
 iiiiisidered as allied to Apocrypha, of the 'I'dielirioinda!, a view 
 ;iilopted liy Laeordaire ; iiut the open antcri(jr coxal cavities 
 tirbid such an a.ssoeiation. The (irst and second ventral segments 
 iippear to be cunmite; should dissection confirm this oi)servatioii,

 tlio middle coxiu extend partly over tlie hind coxie; tin; siile 
 pieces of tlie nieso- and nietatliorax are enlirely covered iiy llie 
 elytra; llic claws are sometimes armed with a tooth, sonietiiiiiN 
 cleft to the l)ase; in this case the upper portion is never pecli- 
 iiate, as in certain genera of the next tribe. Tlie frontal siitini 
 is distinct, and the front is prolonged before the insertion of tlie 
 aiitenuic. 
 
 Our genera are : — 
 
 Claws tnotbe<l near the base; 
 
 Klytra bufrer tliaii tin' abdemeii, inflated, connate. Cysteodemns 
 ]')lytra .■•!i(irt, divei'gent Iroui tin' snitelluni, abdomen vi'iy lar.i:i'. 
 
 Mogetra. 
 
 Claws elel't, tbe nppei' and lowi'v imrtions ecjual ; 
 
 Klytia slinrt, imbricated. Meloe 
 
 Klytra moderate, sLibeonnate. Heaious 
 
 Claws with tbe lower poition sborter than tbe upper, and connate with ;' 
 Klylra nioib-rate, contijjnons for a sbort distance at base. Poreospasta. 
 
 Meloe is generally diiTused, and is the only genus represeuhd 
 on the Kastern Continent; Ileuous is found from Kansas i" 
 Texas; Cysteodemns in Arizona and Colorado Desert; the genu- 
 Miuji'lra T,ee. (Arcana natniw, i. 1:27) is foundi'd upon Mi'loc ciin- 
 (•t'llrilt(ti Va\. and Ci/shddi'iKiis villains liCe., which occur in New 
 -Mexico and Arizona. J^onospasla jiolita Horn occurs in Caii- 
 I'oinia. 
 
 Tribe II.— CAM'IltRIXI. 
 
 Itody generally \i'inged : elytra, in our genera, no' shorter Ihnii 
 the aliiloinen, entirely closing together along the suture; nnia- 
 sterniiia usually long; middle coxiE not overlapping the hiicl 
 coxu; ; side ]iieces of meso- and inetatliorax plaiidy visible, leH

 DIVISION I. 
 
 Tills division contains tiiose jyeiiera in wliich the niesosternal 
 epiiiiera are small, or at most moderate, the epislenia in eoiitaet, 
 with the elytral margin, the nietasterna! side pieces rarely of more 
 tliiin moderate width and not dilated at anterior end, and without 
 the trianjriilar process projecting lietween tlut ines-epiniera and 
 the metaslernnni. The other characters of the d'vision are ex- 
 tremely variahle, in all, iiowevi^r, the antenmu are strongly geni- 
 culate. All the genera of this Division in our fauna have a large 
 laentiiin concealingentirely the maxiihe, (.'xcepting in the last tribe. 
 
 The following tribes are represented in our fauna: —

 vlillilrriiii and 0/ihri/astiiii, ami the character must be strictiv 
 interpreted. Tli(! latter trib(! has the ocular lobes sometimes 
 very feeble and almost wanting, but as the lobes disappear the 
 funbria' become more evident. In the former tribe there are no 
 evidences whatever of either ocular lobes or (imbriiu. In oik! 
 genus, the prosteriium is more emargiimt(^ than usual, giving an 
 appearance of slight ocular hjbes, i)ul ini traces whatever ol'timbria! 
 are seen. In some' of the genera of (>/iliri/(ixliii!, the metasternal 
 Mih pieces become of moderate width, showing somewhat of an 
 approximation to the genera of the second division. Tin; sid(i 
 pieces in the other two tribes are very narrow and the sutures 
 marly always obliterated.

 The group, as cjinprised in the following table, i.s not precisely 
 that intended by Lacordaire. There are without douljt several 
 genera which should be placed in his L'reinnidctf, l)nt with the 
 exception of IMiy.xelis we can tind no genus presenting such 
 marked ilill'erenees in the form of the scrobes as to render it 
 possible to draw the line with any degree of accuracy between 
 those genefu in which the scrobi^s are strictly lateral and iho-se 
 with the scrol)es arcuate and directed inferiorly. 
 
 The arrangement of the genera in the following table exhibits 
 a gradual transition in the form and length of the rostrum, from 
 Dielio.xenns which approaches I'lost nearly Ophryastes in this 
 respect as well as in the structure <if the scrobes and alidomeii, 
 to Phyim\tinus with a long rostrum almost entirely lateral serolies 
 and normal abd'nnen. Cimbocera by its narrower tarsi and the 
 strnctnre oi" >.ie antenna' approaclu's Oidiryastcs in another tlirec- 
 tion. Mt'laniv mi)hus reseniiiles Ainomphus in form. 
 
 The following tal)le is the result of a study in which the serial 
 arrangement e.xhiliits — 
 
 /V/",s/, a gradual iransi'ion in the form of the rostrum, from the 
 more robust to (he elongate. 
 
 Si'foiHl, the tendency of the scrnl)cs to change from the strongly 
 lU'cuaie to tlie nearly straight, and shallow form.

 Tiie validity of the separation of this as a distinct group in

 of which it nisiy be distinguished from the preceding group is 
 found in the position of the scrobes. We have adopted a group 
 iiiiiiie in accordance with the only genus known to us, as experi- 
 ence has alreaily shown that groups of genera formed on the 
 'laeordaireiin basis are not ut all limes e(piivalent to tliose

 The Poritcli should follow the Otioi'iiynclii ffom their fi'rentiT 
 .^iniilarily of form and stvietiire, the only difference between ihc 
 two groups is found in the form of the claws. 
 
 (Iroup 1. — Agraphi. 
 
 Antenna; moderate, scape longer than the funicle and chili, 
 moderately arcuate; funicle d-joiiited; club brotully oval slightly 
 flattened, composed in great part of the first joint only, the oilier 
 joints retracted and very indistinct. Tarsi long, slender, tiiini 
 joint very IVebly eiiiargihate tind scarcely wider than the secdiid. 
 Iliiid lilii.e trunciite at tip with l)roiid, oval smooth space, coiyjoid 
 cavities inlernal. Anterior til)i!e with outer apical angle slightly 
 prolonged; iiiiterior and ndddle tibiie witli inner angle mucroiiiile. 
 
 The id)ove characters appear to warrant tiie separation of 
 Agraplius as a groni» by itself, as suggested by liaccu'daire, who, 
 however, failed to not ice the structure of the anteiinal club ;niil 
 placed the genus in a group in which the cotyloid cavities of himl

 The species of this siili-raiiiily may he recognized hy the nian- 
 dihles being rarely eiiiargiiiale at tip, lull cither bi-eniarginatc 
 with three apical <'iis|is. or ob|i(nie, with three cusps on the inner 
 side, which soinetinies become ell'aced or obsolete. Jii the lir.-i 
 tribes the inferior cusp is also .-iiaiilcr, and less prominent, but it 
 sjieedily becomes more developed, and it is liy the final dominance 
 of that cii-p. with the edge of the mandible which correspond.- 
 to it, that the oblicjiie form with the teeth on the inner edge, is 
 nssirned; and a still greater iiroinineiice of this inferior edge and 
 cusp re.-nlls ill liie olili(pie or (lalleiied fiiriii of nmndible seen i 
 certain CrypiorhynchiMi and ISarini. \'r

 oiii lh"iii the traiisilioii 
 
 n which the mandililc- 
 
 are still more dejircssed, and the condyle instead of being on the 
 outer side comes to the upper siirfiicc, po that the movemunt is 
 vi'rlienl, instead of hori/.ontal as in all other Coleoptera. 
 
 It must also I 
 
 le oliservcd that in certain 
 
 riivt 
 
 niomini the inte- 
 
 rior cusp becomes very small or obsolete, so that tlu^ mandil)les 
 seem to be only emarginate at tip. They thus approach the first 
 three siili-faiiiilies. but are readily known by not possessing tin' 
 peculiar characters which distinguish each of them. The beak 
 is not short and Hat, anil the eyes are not round, as in Silo-

 ligiila and palpi promiiieMt. smaller than in Ilylobiini. The beak 
 is eylimlrieal, sometimes very long and >len(ler, sonu'tinu's rather 
 stout: the anteniial grooves ecimmenee at a distance Ironi the tip, 
 descend obli(piely. and soinetimes become eonlluent bi'hind. The

 The penns Stenopidmiis is inelnded liy'Laeordairi! in his frrou)) 
 Slorcidi'.-', Init it si^enis that the reniarUalile coinliinalion of char- 
 acters I'cipiires tinit it should he received as a separate group, 
 witii the rollowini;' dclinitioii: — 
 
 l>ody clothed with ii deii.-e crust of scales; heak short and 
 l)roa(!, not lon-icr than the head; anteiinal grooves vcry_short. 
 Antenine iii.-erted on the upper rather than the lateral surl'ace, 
 scape long', reaching' to the liack part of the eyes, which are round, 
 and coarsely granulated ; fuidcidus 7-joiiiletl, lirst joint longer and 
 stouter, remaining' joints short, closely united; cluh oval, pointed, 
 entirely pubescent, anmilated. rrolhorax ()i)li(inely' truncate in 
 front, witiioiit postociilar loins, longer on the disk than at the 
 sides; prosteriuim extremely short, not einarginate in front. 
 I'llytra much wider than the prothmax, humeri nearly rectangu- 
 lar. Ventral segments, lirst, second, and lifth very large, third 
 and fourth vei'y short, la>l ventral suture slightly curved. Legs 
 slender, thighs not tootheil; tiliia' truncate at tip, very slightly 
 inucromitc; tarsi narrow, third joint not broader, slightly einar- 
 ginate; fourth joint as long as the two prc'ceding; claws slender, 
 divergent. 
 
 This group diverges towards I'rionomerus in the form of tlie 
 head and anleniue, but otherwise has no reseinblauce to that 
 genus. 
 
 •Stenopeliuus extends from the Atlantic to the I'aL'illc region. 
 
 (iiinip VI. — Brachypi. 
 
 Tlie genus Urachypns is placed by liacordairo in his group 
 Hrirliinides ; it dillers from the otlier genera of that division by 
 the narrow linear form. Though the three species described 
 below do not exactly agrei! with the generic description given by 
 Schouherr and lincordaire, we think tliat they accord sulliciently 
 to indicate tlie proiiriely of associating them logctlier a.s a special 
 group. 
 
 As here established, the lirachypi are nearly related to Ilydro- 
 nonii, but diU'er i)y the ihinl joint of the tarsi being nwrc or less

 Itcak long and usually slender; antenna' inserted far from the 
 tip; antenna] grooves directed soniclinies against the eyes, sonie- 
 tinies helow them. The eyes are rounded or nearly so, not finely 
 granulated. 'I'lie fnniele of the antenna' is (i- or "-jointed, and 
 the cinl) entirely puljcscent and annulaled. The prothorax has 
 no postocular lolies; the prosternuin is .--horl, not strongly eniar- 
 ginalc in front, and the eo.xa; are contiguous. Tiie side pieces nf 
 tlie nu'sothora.x are diagonally divided, and the epimcra do nut 
 largely attain the hasi; of the ])n]thora\. The nu'tasternuin i.-

 A triiie wliich contains a I'vw .-iiiidl species of olilong elongate

 imleiinal grooves descend o'ili(|iiely to the lower edgi' of iIk; eye-, 
 wliicli are moderate in size, nearly round, coarsely granulated ai 'i 
 disiaiit from the prothorax. The anleiime. inserled one-foiiii.;

 siit'cies, though di.'^tinclly scjiaratcil in the foreign gcnei'u; it i's 
 not Linai'ginulu in front, and the prosturnul sutnrcs are ooiiieruted. 
 The clyirii arc .-carceiy wider liian the jirotiiorax, parallel on the 
 .sides, ciHijointly rounded bcliiud, so as to cov(!r the pygidiuni ; 
 the .snrlace is inmclulatc, and the stria; are obsolete. The middle 
 coxiu are nioderiiteiy separated ; the side pieces arc diagonally 
 divided, and the cpiiMcrii attain widely the liase of the prothorax 
 liencalh, though ihey do not iiilcrveiie lietwcen the elytra and the 
 ])ronotiini. Metastcrnuin umdcrately long, side pieces narrow, 
 wider in front. I'^irsl, second, and liflh ventral segments long; 
 third and fourth united aiiout ciiiial to each of tiieui ; surface 
 rather Hat, siiluri's fine and well imiiressed, nearly straight;

 segment is slightly visilile at tiie ti)) of the filth ventral. Legs 
 rather stout, thighs compressed, not toiilhtil; tiliiic truncate at 
 tip, not miK'ronate; tai'si sjiongy heneath; third joint broad, 
 deeply hilolied; ehiws divergent, broadly toothed in our .species; 
 simple in the foreign genera. 
 
 While 1" .ing a slight I'elation with the Alagdalini and .\iitlio- 
 noniiiii this tribe adds to the characters il has in common with 
 ihcni and other tribes, one peculiar to itself; the prostcrnuni very 
 long in front of the coxie. 'I'lie sjiace lietwcen the front eoxic is 
 almost impereeptibie in our two species, but as the descriptions 
 of the foreign genera iiieniiiui them as moderately distant, we infer 
 that that cliaracter, as well as the form of the claws, must be 
 regarded of small value in this tribe. 
 
 Three species of Notolonius, two on Chaimvrops palmetto and 
 one on Myrica, in {'"lorida, represent this trilic.

 'I'liis trilie is composed of ii single genus [.aMiiosaccus, of 
 which one sjiccics occurs in our fauna. It is easily known by 
 the exposed pygidium ; the larg(\ ])roniineiit, and distant front 
 coxic, and the iireast not ehaniielleil. The sidi iiicecs of the 
 mesothorax are very transverse, and intervene simit what between 
 the prothorax and elytra; the episterna of mefatlierax nrv wide, 
 and the cpimera are visilile behind. The ventral sutures arc

 The iieak i.s short, stout, and eylimlrieal; the aiitenind grooves 
 extend to the lower nmrgiii of the eyes, whieh are oval and

 seareely geiiieulated ; the I'uuielu eonsists of seven joints tind 
 nu'rges gradually into tiie oval, annulated, puheseenl elid). There 
 is nothing peeuliar in the mouth; the gular pedunele is long, ihe

 In this group the pectoral groove is connned to the prosternmn. 
 and is not closed behind; the nu'sosternuni is sometimes flat, some-

 ]tartly covered in repose by tin; protlioraeic lobes, which are 
 sometiines very well developed, but in other genera arc broad

 The prolhora.x is, in most species, comparatively snniller than 
 in the other groups, and usually very coarsely scniptnred. 'i'lie 
 elytra are wider than the prothora.x, with prominent humeri, the 
 oilier stria is usually abbreviated, and there is a tendeiiey to an

 Tiio habits, therefore, of these insects, as well as tlusir peculi-

 given to them. 
 
 The .snioolli eyes, tlie reticulations of wiiieh arc seen only

 nature <M'iginating in the same period of time. Tliu geographicsil 
 distribution of the Jirciithichu is also favorable to tlio Idea that 
 lliey rei)reseiit a tolerably ancient form of life. 
 
 The great extension of the longitudinal axis of the body exceeds 
 III s(uiie nu-miicrs of this faniily any proportion that Occurs in 
 other C'nieoptera; and it is singular to see that a character, which 
 usually indicates feebleness <if development, is here associated with 
 densely cliitinized integuments, and great eomiilication of domestic 
 
 life.

 small, rounded, and very coarsely granulated; the result of ;liis 
 fo;-m of head is that the eyes are silinUeil on tin: l)eak instead nf 
 at the sides of the cranium proper. The seutellum is not visible 
 in either <if our genera, and we are inclined to lielieve that this 
 will be found a character of the group, permitting the association 
 of I'orius not widely separated.

 Trill.' II.— C*OSSOXI\I. 
 
 We a.«sociate as a distinct tribe certain otiier genera, which 
 have not the body covered with a crust, but shining ami liarc; 
 some of tlie foreign genera are intu'e or less setose, liut ours are 
 glidirous, with the e.Mcptinn of llimalium. 
 
 'I'lie beak is never very short, and is fre(|Uently dilated at tip; 
 the antenna' are inserted near the tip cu' at the middle; the 
 antcnini' grooves fre(pu'ntly descend r.'ipidly on the sides of the 
 beak, an<l soinetinn.'s are directed towards the eyes, but the 
 fiuienuie are not received in repose in a deep transverse gidar 
 groove as in the next tribe. 'I'he club varies in form, and in our 
 genera thefiinirlc is T-jninted; wjiclher any of the genera of (it her 
 e()i:iiiries, with less ninnber of joints in the fiinicle, belong to the 
 tribe its here constituted, must be dctermiiu'd by sui)se(pient in- 
 vestigations.

 Tribe III.— RIIYXC'OIJXI. 
 
 The genera of this trihe wiiile dilfering Voni those of the Cos- 
 soiiini only iiy having the prosteriiuiii ve/y narrow helweeii the 
 coxa', ami liy having a deep transverse giilar groove lieiieatli in 
 front of the eyes, exhihit other eliiiraeters whieh show a strong 
 approximation to the Seolytiihe; thus I hi' iinuilier of joiiiis in the 
 fiiniele of the aiileiiiiie varies so as (o lie barely of generie value; 
 the lieak heeonies xei'v iiuieli shoi'leiied. and the lieail compara- 
 tively larger, as in Steiioseelis; the ronn of the clnl) varies, he- 
 eoiiiing wedge-shaped, trnnenle, and spmigy at lip in Wollaslouia, 
 thus r\'alling the form seen in Uhyiieliophonis, I'tc. ; (piite rounded 
 or p(-rliaps a little transverse in Sienoseelis. The I'nnii is also 
 that of eertain Seolylid;e. Uhyneolus resendiles closely one sei'- 
 tion of llylasles, while Steiioseelis has allogeilier the appe;ii'anee 
 of llyliirgops ( //. riKii/ii'iniiK, ('\r.). 
 
 As in the Khynehoiihora, from tin,' nearly perfect representation 
 of jiast and present forms, there are almost always intermediate 
 g"iii'ra. to li(\ found, so in I he present trihe IMiUeopluigus seeui-; 
 to he one of such intermediates, and would he in place in the pre- 
 ceding trihe, did we not regard the approximate front eoxie as 
 having greater systematic value than the longer heak and the 
 weaker gular groove. 
 
 The untennul grooves always comnience near the tip of tlic 
 heak ami derjcend ohliipiely heluw il'e eyes.

 joint of the tarsi less dilated, loiifrer ,iiid tiioiifih deeply emarjti- 
 iiate at tip, concealing the third joint so that the urticiilation is 
 not visible from above; but merely the lobes, which do not extend 
 beyond the iirolonged angles of the second joint. The beak is 
 (hit and parallel on the sides; the anteniial cavities extend to 
 the eyes, wliich are ovaJ and coarsely oraniilated, somewhat trun- 
 cate ill front. Tli(^ side margin of the i)rothorax extends to alioiit 
 the middle; the base is .slightly bisiniiale, and the lower basal 
 margin is very well deliiied, so that when tlu? jirothorax is de- 
 flexed, it might be sujiposed that the transverse ridge was not 
 absolutely basal. The same is tlie case, tlioiigh to a less extent, 
 ill the g(Miera of the preceding group. Tlie front coxic are con- 
 tiguous, and the iiientiiin is but feebly emarginate in our s[iecies;
