[Extract from Vol. VI : Annals of the New York Acadbmy of Sciences.] 557 VII. — Coleopterological Notices. IV. BY THOS. L. CASEY. Read May 9, 1892. The following pages are principally confined to studies in our Khynchophora, taken up some time since for the sole purpose of distributing the nondescript material, forming a considerable part of my cabinet, with a measurable degi'ee of scientific order and succession. As usual in such cases, the compass of the work gradu. ally outgrew the limited and personal objects had in view at the beginning, and the investigations in several genera and groups became sufficiently advanced to suggest the propriety of publishing them, with the hope that they might i>rove useful to others similarly engaged. There is but little further to state in way of introduction. The studies have been limited for the greater part to those groups which appeared to stand most in need of revision, either by reason of the large number of specific forms recently brought to light, especially by skillful collecting in our western country, or because of apparent misconception regarding generic identity, as in the case of the group Desmorhines of LeConte. This section of the Erirhinini corre- sponds with the Smicronychina of the European fauna, where it is represented only by the genus Smicronyx, characterized by its con- nate tarsal ungues and the basal constriction of the rostrum. In our own fauna it is rather more abundant and diversified. The Barini, or Baridiides, to which the greater part of the pre- sent paper is devoted, constitute probably the largest tribe of American Curculionidae, and, in South America, form the most varied and characteristic element of the family, possibly excepting the Zygopini. It is interesting to note in this connection, that the recent researches of Mr. S. II. Scudder on the fossil beetle fauna of Annals N. Y. Acad. Sci., VI, Aug. 1892. SfiO Coleopterological Notices, IV. several of our western Tertiary horizons seem to show that the relative importance of the Barini in America dates from some- what remote geological epochs. New York, May 9, 1892. CIIRCULIONID.E. Erirhinini. DORYTOMUS Stepli. The separation of this genus from Erirhinus is largely a matter of convenience, as the femoral teeth, constituting the principal dis- tinguishing feature, are subject to great specific variations in devel- opment, sometimes being barely distinguishable even on the anterior femora, where they are generally most distinct. The genus presents also considerable diversity of structure, and a very noticeable lack of uniformity in the degree of sexual disparity, the three species of the first group having extremely marked sexual differences pervad- ing the entire anterior portion of the body. In the second group, also consisting at present of three species, the sexual divergence is still strong, although much less marked and affecting onlv the beak and antennae, while in the third and by far the largest section the sexual differences become very feeble. In Dorytomus the body is oblong or oblong-oval, generally some- what stout, more or less flattened above and frequently subinflated behind, strongly punctured, especially in the elytral strife, and with pubescence which is composed usually of short robust decumbent hairs condensed in feebly defined spots, or, rarely, of scales similarly uneven in distribution, generally without, but occasionally with, erect bristling setffi in addition. The colors are usually rufo-testa- ceous in different degrees of intensity, rarely becoming piceous or black and more frequently paler ochreous or flavate. The tarsal claws are slender, divaricate, very strongly arcuate, swollen inter- nally near the base but never distinctly toothed. Other structural characters will be referred to in the table given below. The species are rather numerous, generally well characterized structurally but variable in coloration. They belong especiall}^ to the arctic fauna, extending southward in North America as far as Goleopterological Notices, IV. 301 Arizona, and probably also throughout the elevated central region of Mexico. The following tabular statement may possibly facilitate the iden- tification of the greater part of those species at present known to collectors : — Anterior legs elongated in the male ; beak long, slender, strongly, evenly arcuate at least in the female, the antennae inserted near the middle in the latter sex ; femoral teeth minute ; species large and homologous with the European hnr/iinanus 2 Anterior legs not elongated in the male ; beak long and slender, much longer and with the antennre inserted at or near the middle in the female ; species moderately large 3 Anterior legs not elongated in the male ; beak shorter, stouter and more nearly straight, the antennse inserted near apical third in the male and but slightly less apical in the female ; species smaller 4 2 — Elytra with long sparse erect and bristling setse ; beak in the female much longer than in the male; basal joint of the anterior tarsi extremely elongate in the latter sex 1 inaeqiialis Elytra with short and more close-set erect setse ; beak not much longer in the female ; basal joint of the anterior male tarsi subequal in length to the remainder 2 breTisetosilS Elytra devoid of erect setse ; beak only very slightly longer in the female ; basal joint of the anterior male tarsi a little shorter than the remainder. 3 muciclus 3 — Anterior femur of the male with a rather small, very acute tooth.

Sutural notch triangular, deep and clearly limited, each elytron being acute and minutely subprominent at apex ; condensations of the elytral vesti- ture almost obsolete 17 marginatum Sutural notch subobsolete, each el3'tron broadly rounded ; elytral conden- sations well marked. Pronotum with four small condensed spots in a i^osteriorly arcuate trans- verse line ; head with a deep frontal fovea IS indiffereilS Pronotum without trace of the four spots transversely arranged, but with two approximate, sparsely pubescent vittse along the middle, and a lateral vitta, dilated at the middle and inclosing at this point a small subglabrous spot; frontal fovea obsolete 19 Tagenotatus 11 — Prothorax strongly transverse, with the apex much narrower than the base 12 Prothorax small and but slightly transverse, the apex nearly as vride as tl»e base 13 12 — Coloration pale.

Am. Ent. Soc, XVIII, pp. 262, 265)^ under the names Ah/codes dubius and EUeschus angustatus. I have not studied the types of these species, but dubius seems to be allied to the normal eastern forms such as indifferens ; angustatus is almost certainly closel}- related to sqaa- mosus, a small narrow species, with the femoral teeth very small, the anterior alone distinct. In regard to Erirhinus lutulentus and rutilus of Boheman, but little can be stated positively. The description of the latter seems to apply very well, however, to Anthonomus nubilus Lee, while £. lutulentus may possibly be the same as Anchodemus angustus Lee. It is more than probable that the true affinities of EUeschus lie strongly in the direction of Dorytomus, and that the toothed claws form an exception of no more relative importance than the simple claws of certain of the Anthonomini. It will in fact be found • It should be stated in passing, that the genus Euclyptus of Dietz (1. c. p. 271) seems to be identical with Phyllotrox Sch. This genus is widely distri- buted throughout North America and at least the northern part of South A merica, also in the intervening islands. To tlie nine species mentioned in the Munich Catalogue, should be added nubifer a.nd ferriK/ineus Lee, and tesUiceus Dietz; there are several other species in my cabinet still undescribed. Phyllotrox is one of the characteristically American genera of true Erirhinini, and is decidedly out of place in the Anthonomini. An.vals N. Y. Acad. Sci., VI, Aug. 18J2.— 25 364 Coleopterological Notices, IV. extremely difficult to maintain the Erirhinini, Anthonomini and Tychiini as satisfactory triljes, their limits being not at all well defined under the present scope. It would be more in accordance with natural affinities to unite them, and the resultant tribe might then be readily subdivided into numerous well-marked groups or subtribes. 1 I>. inaequalis n. sp. — Oblong, slightly sabcuneate, feebly convex ; integuments black, obsoletely mottled with testaceous, especially laterally ; vestiture rather dense but not altogether concealing the shining surface, somewhat line, moderately long, subrecumbent, finely and confusedly mottled paler and darker, with numerous long erect and bristling setae. Head with a large deep frontal fovea, the eyes large, feebly convex ; beak long, equally, evenly and rather strongly arcuate throughout in both sexes, two-thirds longer than the prothorax, deeply punctate and longitudinally sulcate, with the antennae inserted rather beyond apical two-fifths in the male, slightly more slender, very much longer, fully two-thirds as long as the body, cylindrical, finely but closely seriato-punctate, with the antenna; inserted at the middle in the female. Prothorax in the male large, transversely oval, fully as wide as the base of the elytra and more than one-third as long as the latter, in the female much smaller and more transverse, distinctly narrower than the base of the elytra and scarcely more than one-fourth as long as the latter ; punc- tures rather coarse, deep, moderately dense. Elytra with the sides straight in basal two-thirds, nearly parallel in the male but feebly divergent from the humeri in the female, obtusely parabolic in apical third ; striae slightly im- pressed, the punctures coarse, very deep and approximate ; intervals nearly flat, finely, not densely punctate. Abdomen finely and densely punctate. Length 5.4-6.5 mm. ; width 2.3-2.8 mm. California (Los Angeles). The sexual differences in this species are more pronounced by far than in any other within our fauna. In the male the basal joint of the antenna! funicle is but slightly longer than the next two, the anterior legs slender and very long, the femur and tibia each one- half as long as the entire body, the latter evenly, feebly arcuate and slightly spijiulose along the inner margin, and the corresponding tarsi have the basal joint longer than the remainder and but slightly shorter than the prothorax, with the inner edge finely and unevenly serrulato-granulose. In the female the second joint of the funicle is slightly longer but not as long as the next three, and the anterior legs are normal, the tarsi stout, with the basal joint shorter than the remainder. This species has been confounded wnth miicidutt heretofore, but differs greatly as may be judged by the description. Coleopterological Notices, IV. 305 2 D. lireTisetosilS n. sp. — Oblong, very feebly convex above ; integu- ments rather sliining, piceous-black, confusedly mottled with rufous, especi- ally toward the sides ; vestiture rather dense, moderate in length, subrecum- bent, confusedly mottled and with numerous very short erect setfe. Heud Very densely pubescent, especially above the eyes and with a deep frontal fovea ; eyes large, feebly convex ; beak in the male two-thirds longer than the prothorax, feebly arcuate, coarsely, deeply, rugosely punctate and longi- tudinally sulcate, with the antennae inserted slightly beyond the middle, the basal joint of the antennal funicle as long as the next three ; in the female the beak is a little more slender, evenly and strongly arcuate, much more than twice as long as the prothorax, smooth, more finely, sparsely punctate, with the antennae inserted a little behind the middle, the basal joint of the funicle as long as the next four. Prothorax not coarsely, deeply, somewhat sparsely punctate, with an impunctate median line ; in the male it is trans- versely oval, slightly narrower than the elytra and about one-third wider than long, in the female smaller, more transverse, more broadly truncate at apex, much narrower than the elytra and about one-half wider than long. Elytra three-fourths longer than wide, the sides straight and parallel in the male or feebly divergent from the base to apical third in the female, the apex obtusely rounded, the sutural notch rather large and distinct ; strial punc- ture rather large, deep, closely approximate ; intervals finely, somewhat dis- tinctly and closely punctate. Ahdomen rather strongly, not densely, unevenly punctate. Length 5.7-7.0 mm. ; width 2.3-2.9 mm. Arizona. This species is closely related to mucidus, but may be distin- guished by the slig-htly longer beak with the antennae a trifle less apical in insertion in both sexes, by the abundant, erect but short setge, bristling throughout the dorsal surface, and by the relatively more elongate anterior legs of the male, the basal joint of the tarsus in that sex being about equal in length to the remainder; it is dis- tinctly shorter in mucidus. 3 D. mucidus Say.— Cure. 14, Ed. Lee, I, p. 277 (Erirhinus) ; Gyll.: Sch. Gen. Cure, III, p. 291 ; Lee. : Proc. Am. Phil. Soc, XV, p. 1(J4. Oblong, flat above, convex at the sides, somewhat densely clothed with short robust pointed and subrecumbent hairs, which are whitish in color and with barely a trace of sparse and extremely short semi- erect setae toward apex only ; integuments black and rufo-testaceous confusedly mottled. Beak slender in the male, feebly arcuate, coarsely, densely, rugosel}^ striato-punctate, about one-half longer than the prothorax, with the antennae inserted at apical two-fifths, in the female more strongly arcuate, cylindrical, smooth, finely, less densely, confusedly punctate, twice as long as the prothorax, with 366 Coleopterological Notices, IV. the antennae inserted at the middle ; antennae slender, with the basal joint of the funicle about as long- as the next four together, the second as long as the next two, differing but slightly in the sexes. Prothorax larger and longer in the male than in the female, one- half wider than long and but slightly narrower than the elytra in the former, three-fourths wider than long and much narrower than the elytra in the latter; sides strongly arcuate, rounded and con- vergent but not at all constricted near the apex ; disk strongly but not very coarsely punctate, the punctures distinctly separated. Elytra parallel, ogival toward apex, from two-thirds to three- fourths longer than wide, the strial punctures coarse, deep, moder- ately close-set, the intervals feebly convex, minutely, feebly, rather sparsely punctulate. Length 5.0-6.5 mm.; width 2.0-3.0 mm. Canada, Indiana and Nebraska. The sexual differences are slightly less pronounced than in breviselosvs and very much less so than in ineequalis, and this species is readily distinguishable from both by the absence of erect setae. In the male the anterior legs are elongated, but the basal joint of the tarsus is shorter than tiie remainder and about one-half as long as the prothorax. 4 D. laticollis Lee— Proc. Am. Phil. Soc, XV, p. 164. Piceous-black, variegated with small distant spots of rufo-piceous, polished, the vestiture sparse, consisting of short robust and recum- l)ent hairs, condensed in numerous small paler spots and also toward the sides of the prothorax, without trace of erect setae. Head strongly, not very densely punctate and with a deep frontal fovea ; beak very slender, cylindrical, in the male strongly arcuate, straight toward base, rather finely but deeply, linearly punctate and fully one-half as long as the elytra, very finely, sparsely and inconspicu- ously setose, the antenna? inserted just behind apical third, the basal joint of the funicle fully equal to the next three. Prothorax small, transverse, three-fourths wider than long, the sides abruptly rounded and strongly convergent anteriorly, the apex very briefly tubulate and broadly arcuate, three-fourths as wide as the base; punctures deep, perforate but not very large, rather sparse, the median im- punctate area very feebly defined toward the center only; apical margin rufescent. Elytra at base nearly one-third wider than the prothorax, almost four times as long, slightly wider behind the iniddle, broadly constricted behind the humeri, the strial punctures coarse, deep and close-set ; intervals nearly flat, finely but strongly, Coleopterological Notices, IV. 307 rather closely punctate. Abdomen finely, not very densely punc- tate. Length 4.4 mm.; width 1.9 mm. The description is drawn from a male taken in Michigan. It also occurs at Lake Superior and in Iowa according to LeConte. f) D. aniplUS n. sp. — Oblong, feebly convex, robust, strongly shining, pale brownish-Havate thronghout ; vestiture very sparse, consisting of small robust and recumbent hairs, feebly condensed in subtransverse wavy lines on the elytra behind, also denser at the humeri ; erect setae completely wanting. Head finely but deeply and rather densely punctate and setose, the frontal fovea small but deep ; beak in the male slender, strongly arcuate, evenly cylindrical, finely but deeply, rather closely lineato-punctate, very slightly more than one-half as long as the elytra, with the antennae inserted near apical two-fifths, first funicular joint as long as the next three, second equal to the following two combined. Prothorax small, transverse, nearly three- fourths wider than long, the sides sul)parallel and strongly, almost evenly arcuate, not very abruptly rounded near the apex but distinctly constricted, the apex truncate, very broadly tubulate, more than three-fourths as wide as the base; punctures rather fine but deep, quite sparse, the impunctate line narrow and not attaining the apex. Elytra at base nearly two-fifths wider than the prothorax, about four times as long as the latter and scarcely notice- ably wider behind the mi.ldle, the sides gradually ogival in apical third, with the sutural notch rather large; humeri rectangular, rounded, broadly ex- posed ; strial punctures rather small but very deep, perforate and close-set ; intervals flat, very minutely feebly sparsely and inconspicuously punctate. Abdomen finely, distinctly, subrugosely punctate. Length 5.4 mm. ; width 2.3 mm. Colorado. A rather large species allied to laticollis and parvicollis, but differing in its entirely pale reddish-ochreous coloration, and much broader form. The two specimens before me are apparently males. 6 I>. parvicollis n. sp. — Oblong, moderately stout, feebly convex, shin- ing, rufo-testaceous, irregularly mottled with piceous-black, especially toward the middle ; vestiture rather sparse, consisting of short robust and recumbent pale hairs, unevenly and feebly condensed and mottled, without trace of erect setae. Head finely, deeply, very densely punctured and with a deep frontal fovea; beak in the male somewhat stout, feebly but distinctly arcuate, coarsely deeply and closely punctate in longitudinal furrows, strongly and conspicu- ously setulose and slightly longer than the head and prothorax, distinctly less than one-half as long as the elytra, with the antennae inserted just beyond apical two-fifths ; in the female the beak is very long, slender, less sulcate, strongly, evenly arcuate, fully two-thirds as long as the elytra, with the antennae Inserted just beyond the middle ; ba-:al joint of the funicle sub- 368 , Coleopterological Notices, IF. equal to the next three in both sexes. Prothorax small, transverse, about two- thirds wider tlian long, neaidy similar in the sexes, abruptly, strongly rounded and very strongly narrowed near the aj^ex, the latter broadly and rather strongly tubulate, four-fifths as wide as the base, broadly, feebly arcuate, feebly sinuate in the middle ; punctures not very coarse but deep, dense although distinctly separated, the impunctate line completely obsolete. Elytra at base from one-third to one-fourth wider than the prothorax, four times as long as the latter, parallel in the male but gradually distinctly wider behind in the female, obtusely ogival at apex ; strial punctures moderately large, very deep, perforate, close-set ; intervals nearly flat, minutely, feebly, rather sparsely punctate. Abdomen finely, evenly, not densely punctate. Length 4.5-5.5 mm. ; width 2.U-2.2 mm. Indiana. Allied to laticoUis, but disting-uishable by the pale coloration and especially by the shorter, more robust beak of the male and the slightly larger eyes of the same sex ; the beak and head are also much more coarsely and densely punctate and setose. The tooth of the anterior femur is larger in the jiresent species than in lati- collis, and the elytra are parallel in the male and not gradually feebly inflated behind. 7 D. liystricilla n. sp. — Oblong-oval, convex, feebly shining, piceous- black and more or less rufescent toward the sides, to pale rufo-testaceous throughout ; legs always pale ; vestiture dense, consisting of short stout pointed and decumbent hairs, cinereous in color and but feebly mottled, the pronotum Avith two narrow indefinitely nubilate darker vitt;©, the elytra bristling also with long erect stiff setse, not close-set in a single line on each interval. Head and beak very densely punctate throughout, the latter not longitudinally carinulate or sulcate, in the male short, about as long as the prothorax, with the antennse inserted at apical third, in the female just visi- bly longer, but not longer than the prothorax, with the antennje inserted at apical two-fifths, in both sexes feebly, evenly arcuate and stout ; antennae stout, the basal joint of the funicle as long as the next three, second much shorter than the next two, outer joints gradually thicker and transversely oval, club thick, oval, pointed. Piot/iorax oue-haU wider than long, parallel and broadly arcuate at the sides, moderately constricted and broadly sub- tubulate at apex, the punctures not coarse but deep and dense ; impunctate line obsolete. Elytra at base one-third wider than the prothorax, about three find one-half times as long as the latter, the sides parallel and nearly straight ; apical third evenly ogival ; sutural notch broad and rather large ; stri* un- impressed, the punctures moderately coarse, deep, somewhat close-set ; inter- vals minutely, very feebly and somewhat closely punctate. Abdomen closely, rather coarsely, confusedly and subrngosely punctured. Length 2.7-3.3 mm. ; width 1.1-1.5 mm. Coleopterological Notices, IV. 369 California (San Francisco to Los Angeles). One of the most abundant of the Californian species and repre- sented before me by a large series. It varies greatly in color, and closely resembles mannerheimi Gemm. ; the latter, however, com- pletely lacks the long coarse erect seta; which are so conspicuous in hystricida. 8 D, liispidllS Lee— Proc. Am. Phil. Soc, XV, p. 167. Oblong, somewhat stout, convex, feebly shining, pale flavo- testaceous throughout except the sterna of the hind body, which, as in hirtus, are blackish; vestiture dense, consisting of robust recumbent hairs, feebly subdenuded in uneven wavy blotches on the elytra behind the middle, and with coarse erect bristles of moderate length. Head very densely punctate and coarsely pubes- cent, the beak in the female subglabroiis toward apex, very feebly, evenly arcuate, rather slender, not quite as long as the head and prothorax, the antenn® inserted at at)ical two-fifths; between the bases of the antenna? there is a dilated flat polished and impunctate area. Prothorax small, more than one-half wnder than long, parallel and rounded on the sides, convergent and sinuate, but not strongly constricted, near the apex, the latter three-fourths as wide as the base; punctures moderate in size, deep, dense, the impunctate line narrow and distinct. Elytra at base fully one-third wider than the prothorax, much more than three times as long, parallel, gradually, evenly parabolic in more than apical third; strial punctures moder- ately large, very deep and close-set ; intervals about three times as wide as the punctures. Abdomen densely, rugosely punctate. Legs short. Length 3.6 mm.; width 1,4 mm. New Mexico. Cab. LeConte. A distinct species not closely allied to any other ; it differs from hirtus in its smaller, narrower prothorax, and the shorter and sparser pubescence of the elytra, although the erect setse are similar to those of that species in length and abundance; also, as remarked by Dr. LeConte, in the absence of the interantennal sulcus. 9 D. liirtus Lee— Proc. Am. PliiL Soc, XV, p. 166. Oblong, robust, convex, somewhat shining, pale flavo-testaceous, the beak piceous ; sterna and their parapleurje black ; vestiture dense, consisting of long robust recumbent hairs, yellowish-white in color, scarcely mottled but suljdenuded in a large clouded spot 3 TO Coleopterological Notices, IV. near the middle of each elytron ; el3'tra and beak toward apex bristling with stiff suberect setae. Beak in the female not very- stout, evenly, feebly arcuate, as long as the head and prothorax, rather sparsely puactate and siibglabrous except above in basal half, with an elongate indentation between the antennae, the latter inserted just behind apical third, the basal joint of the funicle not quite as long as the next three ; club moderate, not darker in color. Prothorax two-thirds wider than long, parallel and rounded at the sides, convergent and just visibly constricted anteriorly, the apex nearly three-fourths as wide as the base ; disk rather finely, some- what closely punctate, without distinct impunctate line. Elytra at base barely one-fourth wider than the prothorax, three and one-half times longer than the latter, subparallel, ogival in apical third, the striae feebly impressed, the punctures rather small, not very close- set ; erect setae forming a single line on each interval. Length .3.7 ram.; width 1.65 mm. California (San Diego). Cab. LeCoute. Represented by the unique female type. Hirtits is allied to hi/stricula, but is immedi- ately distinguishable by its larger and more transverse prothorax, stouter bodily form, longer beak, very much finer strial punctua- tion and many other characters. The erect setae of the elytra are decidedly shorter and more numerous than in hydricula. 10 D. filiolus n. sp. — Obloug-oval, rather stout, convex, sliinius', pale flavate throughout; vestiture rather sparse, consisting of long, somewhat fine, recumbent and ashy pubescence, not perceptibly variegated, the elytra brist- ling with long sparse and erect bristles, disposed in a single line on each interval. Head and beak finely, rather densely, evenly punctate, the frontal fovea deep but not very large ; beak short, stout, just visibly, evenly arcuate, about as long as the prothorax in the female, not longitudinally furrowed or carinulale ; antennae inserted beyond apical two-fifths, somewhat stout, short, the basal joint of the funicle as long as the next three, seventh abruptly wider, transverse, club short, very robust, oval. Prothorax short and transverse, two- thirds wider than long, strongly rounded on the sides, convergent and nearly straight but not in the least constricted toward apex, the latter much narrower than the base ; punctures rather coarse, very deep and dense but not actually in contact, and with traces of a narrow impunctate line. Elytra at base one- third wider than the prothorax, three and one-half times as long, subparallel, the apex conjointly ogival ; strise feebly impressed, coarsely, deeply and closely punctate, the intervals very minutely, feebly, sparsely and indistinctly punc- tured. Abdomen shining, fin(dy, not very closely, distinctly punctate, sparsely and finely pubescent. Length 2.5 mm. ; width 1.15 mm. Goleopterological Notices, IV. 371 Colorado. The single specimen serving as the type is probably a female. This species is one of the smallest of the genus and is somewhat allied to hijslricula, but differs greatly in its coarser, sparser punc- tuation, sparser pubescence and especially in the form of the pro- thorax, which is shorter, more strongly narrowed anteriorly and not at all constricted behind the apical margin. 11 D. niannerheimi Gemm. — Col. Hefte., VIII, p. 122 (Erirhinns) ; Lee: Proc. Am. Phil. Soc, XV, p. I(i6 ; restitus Mann.: Bull. Mosc, 1853, II, p. 242 (Erirhinns). Oblong, moderately stout, convex, scarcely shining, densely and almost uniformly clothed tliroughout with short robust recumbent hairs of a dark cinereous tint, and without long erect set« ; body black, the legs piceous ; antennte paler, piceous. Beak very short, stout, densely punctured and setose but not longitudinally grooved, opaque, feebly arcuate and ecpiai in length to the prothorax ; antennoe inserted but slightly beyond apical two-fifths, the basal joint of the funiele robust and but little longer than the next two. Prothorax short, fully one-half wider than long, parallel and rounded on the sides, strongly constricted and broadly subtubulate at apex, ex- tremely densely, not very coarsely punctured, without impunctate line. Elytra at base much wider than the prothorax and about three and one-half times as long, the sides parallel and straight, rounded in apical third, with a small sutural notch : striae rather coarsely deeply and closely punctate, not strongly impressed ; inter- vals but slightly wider than the strial punctures, densely punctu- late. Length 2.1 mm.; width 1.25 mm. Alaska. Cab. LeConte. Easily distinguishable from the other Alaskan species by its dense and uniform pubescence and shorter, broader, more parallel form. It is doubtful if the name substituted by Gemminger should be retained, as the south African vesiitus is possil)ly a true Erirhinns. Tiie anterior femora in mannerheimi are distinctly toothed; the others are not in a favorable position for observation in the single specimen \\hich I have studied. The pro- notal vittfe, mentioned by Mannerheim, are obliterated in this ex- ample, and the small subdenuded spots of the elytra are extremely feebly defined. 12 I>. nilliecilliniis n. sp. — Narrowly oblong^-oval, convex, shinincr, sparsely clothed with long white robust and squamuliform hairs, soniewliat 372 Coleopterological Notices, IV. unevenly arranged on the elytra and erect and bristling on the head ; color pale rufo-testaceous ; head and beak blackish, the tip of the latter pale ; elytra with a broad triangular basal area and an elongate narrow subsutiaral spot behind the middle of each blackish ; sterna and side-pieces black. Head very densely punctate, without distinct frontal fovea; beak short, stout, just visibly bent, rather finely, deeply and moderately densely punctate but not at all sulcate or carinulate, in the male barely longer than the prothorax, with the antennre inserted at apical third ; basal joint of the antennal funlcle fully as long as the next three, club moderate, not at all darker in color, with the first joint subglabrcuis toward base. Prothorax short, two-thirds wider than long; sides parallel and nearly straight in middle two-thirds, convergent and rounded near the base, convergent and very feebly sinuate behind the apex, the latter three-fourths as wide as the base ; punctures very dense, rather fine, deep ; median line very narrowly and feebly carinulate. Elytra at base fully one-third wider than the prothorax, nearly four times as long, parallel and straight at the sides, ogival in apical third, the sutural notch subobsolete ; strise barely impressed, coarsely deeply and closely punctate, the intervals not quite twice as wide as the strise, finely, rather sparsely and confusedly punc- tate. Abdomen rather strongly punctate, blackish toward base and in the median parts of the fifth segment. Legs short ; femoral teeth rather large and distinct but acute. Length 3.0 mm. ; width 1.2 mm. Colorado. A suiall narrowly convex species of peculiar coloration, with long coarse and sparse but conspicuous vestiture, and short nou-sulcate l)eak. It is not closely allied to any other form which I have seen. 13 D. luridllS Mann.— Bull. Mosc, 1853, II, p. 241 (Erirhinus); Lee: Proc. Aui. Phil, tioc, XV, p. 165. Oblong-, subcuneiform, moderately convex, polished, rufo-testace- ous, the head piceous ; vestiture rather sparse, consisting of short robust recumbent pale hairs, confusedly condensed and mottled on the elytra, longer and more slender on the pronotum ; erect setae entirely wanting. Head rather coarsely, strongly punctate, the fovea very small ; beak not very stout, almost straight, deeply, coarsely punctured in longitudinal furrows, evenly and just visibly arcuate in the female, straight and slightly bent near the apex in the male ; in the male it is a little less than one-half as long as the elytra, with the antenujB inserted at apical third, the first funicular joint but little longer than the next two, in the female barely one- half as long as the elytra, the antennae inserted just behind apical third, with the basal joint of the funicle fully as long as the next three. Prothorax small in both sexes, nearly one-half wider than long, rather coarsely, closely punctate, with a narrow imperfect im- Coleopterological Notices, IV. 373 punctate line, constricted at apex, rounded and snbparallel on the sides. Elytra at base distinctly wider than the prothorax, a little more than three times as long as the latter, wider behind ; strial punctures coarse, deep and close-set; intervals finely but deeply, evenly, not very closely punctate. Abdomen strongly punctate. Length 3.4-4.3 mm.; width 1.4-1.8 mm. Alaska, Washington State and California (San Francisco and Los Angeles). This is a very abundant, widely distributed and constant species and may be easily recognized by the characters stated in the table. In one immature specimen before me a large region of the elytra toward the suture is piceous-black, confusedly speckled with paler spots. 14 D. rufulus Mann.— Bull.

Abdomen not coarselv, strongly, rather sparsely punctured. Femora not very stout, the tooth small, distinct and very acute. Length 4.3 mm.; width 1.8 mm. Alaska. Cab. LeConte. The single specimen, from which the above outline is drawn, is a female, the abdomen being evenly con- vex toward base. It is quite closely allied to luridus but is a larger, stouter species, with shorter and thicker beak, always pale in color and with decidedly smaller eyes, so that when the insect is viewed in profile, there is a large part of the head visible above them. 374 Coleopterological Notices, IV. 15 D. Clineatllllis n. sp. — Ratlier narrowly cuiieate, convex, polished, hlack throughout, the pronotiim and elytra occasionally with small feehly- marked paler spots near the humeri ; vestiture sparse, consisting of short rohust recumbent hairs, whitish in color and confusedly and vaguely con- densed in spots and transversely wavy lines behind the middle of the elytra.

Abdo- men rather strongly indistinctly and subrugosely punctured. Length 3.3-3.7 mm. ; width 1.3-1. (j ram. California (Siskiyou Co.). A small, somewhat narrow and convex species allied to luridus, but di.stin^uishable by its black coloration and by the much greater sexual disparity in the length of the beak, the latter being actually a little shorter in the male than in the corresponding sex of I u7-id us. The body is narrower and the antenual club larger and relatively longer in cuneatalus. If). D. alaskaniis n. sp. — Narrow, oblong, subparallel, moderately con- vex, shining, piceons-l)lack, the elytral suture and flanks pronotum at base and apex, legs and antennae, except the club, paler ; vestiture very sparse, con- sisting of short robust recumbent hairs, condensed, larger and whiter in very small remote spots on the elytra.

Abdomen finely, sparsely punctured. Length 3.0 mm. ; width 1.1 mm. Alaska. Cab. LeConte. A small species allied to luridus, but narrower, more sparsely pubescent, darker in color nndwith a shorter beak in the male; the antennal club is distinctly longer and larger than in luridus. In form it somewhat resembles suhfasciatus, but the prothorax is less strongly rounded on the sides and the punctuation very much coarser and sparser. 17 D. marginattlS u. sp. — Oblong, feebly couvex, rather dull, rufo- testaceous ; sterna, abdomen except near the apex, a feeble clouded transverse area on the pronotum before the middle, head, beak except at tip and a broad subsutural vitta on each elytron, from the basenearly to the apex, more or less blackish ; vestiture moderately dense, consisting of short robust recumbent hairs, feebly condensed in small and paler spots on the elytra, unevenly denser toward the sides of the pronotum and paler in two small approximate spots before the middle.

Abdomen somewhat coarsely, moderately closely«punctate. Lecjs rather short ; femora stout, moderately but distinctly dentate. Length 3.6-4.0 mm. ; width 1.4-1.6 mm. California. This is a rather distinct species, allied to vagenotatus, but always easily separable by the well-defined abbreviated subsutural vitta. 18 D. illdiffereus n. sp. — Oblong-oval, rather shining and convex, dark rufo-testaceous in color, the head, beak, sterna and the elytra indeti- iiitely toward the middle, black or piceous ; elytral suture always narrowly rufous ; tip of beak pale testaceous ; legs and antennae rufo-testaceous ; vesti- ture rather sparse, consisting of short robust pointed and prostrate hairs, whitish in color, confusedly condensed and subdenuded on the elytra.

Legs rather slender ; femora with a small acute tooth, rather feebler on the intermediate as usual. Length 3.0-4.0 mm. ; width 1.3-1.7 mm. New York; Illinois; Iowa; Kansas. A common Atlantic form, resembling rufus and vagenotatus, but distinguishable by the small and deep perforate frontal fovea, which is completely obsolete in those species, and also by its larger size and different coloration. 19 D. TagenotatllS n. sp. — Oblong, feebly convex above, piceous-black ; abdomen toward apex, legs, antennse except the club, pronotum laterally and a narrow suffused stripe near the side of each elytron paler and more or less rufous; integuments confusedly marmorate with small confused condensed patches of short white pointed hairs, less mottled and almost uniformly pubes- cent along the lateral paler stripe.

The type and unique specimen is a male, the abdomen having- a large rounded and deep impression near the base. It is allied to ritfus but differs in its larger size, coloration, longer beak and more elongate antenna! club, longer legs, more distinct femoral teeth, and in the finer, shorter vestiture, more distinctly defined in white mar- morate patches on the dark elytra. 20 D. nifns Say.— Descr.

Legs short, stout, the femoral teeth minute but distinct on the anterior. Length 3.0-3 2 mm. ; width L3 mm. Kansas. The three specimens before me exhibit scarcely any variation. This species may be readily known by its pale ochreous color, feebly clouded along the median parts of the elytra, the small size, coarse, subsquamiform vestiture and by several other distinc- tive characters. 21 D. flisciceps n. sp. — Oblong, rather broad and snbdepressed, pale oclireous-flavate, the head and beak piceons-black ; sterna piceous, each elytron almost imperceptibly clouded with a darker tint in a broad subsutural 378 Coleoj)terological Notices, IV. area from basal third to apical fifth ; vestitiire very dense but scarcely at all condensed iu spots, consisting of very short robust and decumbent hairs, be- coming squamulose in a small spot at each side of the pronotal disk.

It is allied to rvfus, although very much larger and relatively wider, with denser punctuation and shorter much less conspicuous vestiture. In fusciceps the subapical constriction of the prothorax is totally obsolete; it is broad and almost obsolete in riifus and deep and abrupt iu marginatus. 22 D. brevicollis Lee— Proc. Am. Phil.

Abdomen rather coarsely and closel}^ punctate. Length o.T mm. ; width 1.4 mm. Lake Superior and Minnesota. Resembles rufulus somewhat, but differs in its narrower form, more strongly convergent sides of the prothorax toward apex, the latter being very much narrower when compared with the base, in its decidedly coarser punctuation, especially of the pronotum, and in the coarser, denser vestiture. The two specimens before me are apparently males, and the one from Minnesota is pale flavo-testaceous throughout, probably from immaturity, with the frontal fovea practically obsolete, this not being so constant a feature as it apparenth^ is in indijferens. 23 D. subsignatllS Mann.— Bull. Mosc, 1853, II, p. 241 (Erirhinus). Rather slender, convex, feebly subcuneate ; body piceous-black, the pronotum rufescent toward base and apex, the elytra dark rufo- testaceous, each indefinitely clouded with blackish in the middle to- ward base and also near the apex ; legs and antennae pale, the club of the latter dark.

Length 2.1-3.3 mm. ; width 0.9-1.3 mm. Illinois and Kansas. Easily distinguishable by the narrow con- vex form, dark rufo-ferruginous color and the vestiture, which is dense and distinctly squaraiform toward the sides of the body, but more hair-like along the median parts of the upper surface. The tooth of the anterior femora is very small but distinct, that of the others nearly obsolete. In one narrow male there is a small denuded spot in the middle of each of the lateral squarao.se vittaj of the pro- notum. 26 D. lliarmoreilS n. sp. — Oval, convex, rather dull, black ; aiitennse, legs and elytra in a very feebly defined sublateral vitta rufescent ; vestiture dense, consisting of narrow recumbent lanceolate scales, white in color in two narrow approximate pronotal vittse and a small median spot at each side, and, on the elytra, along the suture and in very uneven discal spots, elsewhere subdenuded and piceous-black.

SmiCROIVYX Schonh. Pachytychius Lee. iiec Jekel ; Desmoris Lee. The genus Pachytychius of Jekel, as represented by the European squamosvs Gyll., examples of which have been recently sent me by M. Desbrochers des Loges, has the beak unconstricted at base and similar to that of Tychius, and the tarsal claws small, simple, divergent and distant at base, forming in fact one of the connective bonds between the Erirhinini and Tychiini. Pachytychius does not appear to be represented in the American fauna, and the two species provisionally placed there by LeConte are entirely identical in all structural characters, which can in any way be considered of generic worth, with the form described by that author as Smicronyx corpu- lentus and the other species placed in Smicronyx. Desmoris of LeConte was founded upon two species of rather larger size than the others, but, if care be taken to examine D. con- strictus, it will be found a perfect homologue of such species as Smicronyx sordidus and griseus, in all points of facics and structure. Smicronyx is a rather large genus, constituting a special group of the Erirhinini, characterized by the strong basal constriction of the beak and the simple tarsal claws which are invariably connate in basal third or fourth. It is somewhat heterogeneous in the ex- ternal aspect of its species, both here and in Europe, but as far as can be perceived is entirely uniform in the essential generic struc- tures referred to, as well as in abdominal structure, in the coarsely faceted eyes, somewhat approximate beneath, and in the deeply sin- uate apical margin of the prosternum. The elytra are, as a rule, distinctly wider at base than the disk of the prothorax, but are not as elongate as in Dorytomus, and are generally acutely rounded behind in apical half, Avith the tenth stria very short and remote from the ninth, closely approaching the latter behind the humeri. The scutellum is small, the legs rather short and stout, the femora unarmed, the tibial spur distinct, and the third tarsal joint dilated and bilobed, the fourth being somewhat short or moderate in length. The species are small in size, and include among them some of the most minute curculionides known to us at present. Those of our fauna may be provisionally classified as follows : — Fifth elytral interval densely clothed nearly throughout with white scales ; second joint of the antennal funicle almost as long as the first ; hody robust, oval, convex, densely but unevenly squaniose...! lilieolatllS Coleopterological Notices, IV. 383 Fifth interval not conspicuously vittate ; second funicular joint very variable iu length but always much shorter than tlie first 2 2 — Elytral scales almost uniform in size and density throughout the disk, uniform in coloration or more or less conspicuously mottled 3 Elytral vestiture very uneven, condensed in subtransversely wavy areas, iu which the scales become larger, denser and generally paler in color 16 3 — Elytra inflated and only slightly longer than wide 4 Elytra not inflated, much longer than wide, parallel at the sides toward base... 5 4 — Prothorax distinctly narrower than the base of the elytra, the latter with a large subbasal area of dark brown or blackish scales.

Length 2.3-3.3 mm. ; width 1.15-1.55 mm. Illinois; Texas. A distinctly marked species, apparently rather abundant. My first specimens were received some years since from Mr. F. M. Webster. In this species the pronotal scales are not arranged like those of corpulei^tus and discoideus, where they radiate from a central point. The punctures toward the middle of the pronotum are also different, being- transverse and not rounded. 2 S. discoideus Lee. — Proc. Am. Phil. Soc, XV, p. 169 (Pachytychius). Robust, oval, convex, black, the legs slightly rufo-piceous ; scales moderate in size, closely decumbent, widely overlapping, white or yellowish-white, the middle of the pronotum broadly, and a large sutural basal and small lateral median area of the elytra, both un- even, clothed more sparsely with blackish scales; recurved sette of the elytra in the form of elongate concolorous scales and scarcely visible under low power.

Tarsal claws slender, feebly divergent, connate in basal fourth. Length 3.0-3.2 mm. ; width 1.6-1.75 mm. Illinois. A well-known species of rather large size and obese form. One badly preserved male before me, taken by Mr. Wick- ham, at Elko, Nevada, cannot be distinguished from the eastern forms except by its slightly shorter beak. 3 S. COrpulentns Lee. — Proc. Am. Phil. Soc, XV, p. 170. Robust, convex, rather broadly oval, black, the legs bright rufous; scales of the upper surface elongate-oval, narrowly truncate at apex, Coleopterological Notices, IV. 387 widely overlapping and extremely dense, yellowish in color, a large suffused sutural spot from the middle of the elytra to the scutelluni, becoming narrower anteriorly, equally densely clothed with brown scales; median parts of the pronotum rather darker, the scales being slightly sparser; recurved setse indistinct.

Length 2 0-2.8 mm.; width 1.0-1.55 mm. Texas (Austin and El Paso); Arkansas and Louisiana. I found this species some years ago in great abundance on the banks of the Colorado River, in June. It is allied to discoideus and differs in its fine elytral stria? toward the middle and base, in the narrower bodily form and smaller size, red legs, and in the color of the vesti- ture. The brown subbasal spot of the elytra is frequently obsoles- cent. 4 S. amoeiillS Say.— Cure. 26, Ed. Lee, I, p. 294 (Tychius) ; Lee: Proc. Am. PhiL Soc, XV, p. 168 (Pachytychius).

Elytra at base two-fifths wider than the prothorax, not quite three times as long, parallel and nearly straight at the sides in basal half, the strise indicated laterally only by the finest partings of the vestiture, more distinct toward the suture. Tarsal claws rather small, connate in basal third. Length 2.2 mm. ; width 1.0 mm. Arizona. The large subbasal quadrate spot of velvety black will serve to render this species easily recognizable. It somewhat resembles vestitus in outline, but is rather stouter. Two specimens. 7 S. profllSlIS n. sp. — Oblong, convex, black, the legs scarcely piceous ; body densely clothed above with large, broadly oval, piceous scales, widely overlapping, feebly and confusedly intermixed with slightly paler scales on the elytra and narrowly paler along the middle of the pronotum ; scales of the lender surface rather paler and not quite so large ; recurved setse of the elytra not conspicuous, more evident anteriorly.

Prothorax convex, parallel and nearly straight at the sides in basal three-fourths, then rounded and deeply constricted ; apex three-fourths as vride as the base ; punctures not very large, round, distinct and well separated. Elytra at base fully one- half wider than the prothorax, not quite three times as long, barely more than one-third longer than wide, slightly widest behind the middle, the apex broadly ogival ; stride strong and not very fine. Tarsal claws moderate. Length 2.8 mm. ; width 1.45 mm. Te.xas (El Paso). Mr. Dunn. The moderately large size, robust convex form, large scales and generally rough hispid appearance will aid in the identification of this distinct species. It is represented before me by a single male. A specimen from Arizona is slightly more elongate, with the beak less punctate and squamose, the antennae being inserted just beyond the middle ; it is probably the female. 9 S. pusio Lee. — Proc.

Length 1.75 mm.; width 0.75 mm. Lower California (Cape San Lucas). Cab. LeConte. A minute but distinct form, not closely allied to any other and readily recog- nizable by the dense crust of ochreous-yellow scales, and the rather prominent third interval of the elytra. It is distinctly stouter than the Arizonian silaceus. 10 S. COrnictllatllS Fahr.— Sch. Gen. Cure, VII, ii, p. 309 (Tychius) ; squamulutus Lee. : Proc. Am. Phil. Soc, XV, p. 173.

Length 2.0-2.4 mm.; width 0.9-Ll mm. Massachusetts and Pennsylvania (near Philadelphia); Michigan — Cab. LeConte. This is one of our most abundant eastern species, somewhat resembling flavicana, but smaller and less mottled. It agrees throughout with the description given by Fahrajus, which was founded upon a Pennsylvania example sent to him by Zimmer- mann. 11 S. imbricatllS n. sp. — Narrowly oblong, convex, black throughout and very densely clothed above with large broad ogival scales, which widely 392 Coleopterological Notices, IV. overlap in a longitudinal direction, blackisli-gray and whitish confusedly intermingled, the latter more prevalent toward the sides ; scales of the under surface smaller and nearly white, extremely dense; recurved setse sparse, dark brown and inconspicuous. Head densely squamulose, the vestiture decumbent ; transverse sulcus distinct ; beak in both sexes densely clothed almost throughout with short sparse setae and large recumbent and close-set scales, tufted and erect at base, in the male short, just visibly bent, stout, scarcely longer than the head and prothorax, the antennae inserted at apical two-fifths, in the female distinctly longer, evenly, distinctly arcuate, scarcely more slender, a little more than one-half as long as the elytra, with the antennae inserted just beyond the middle ; antennae moderate, the second funicular joint nearly one-half longer than the third ; basal joint not quite as long as the next three in the female, slightly shorter in the male.

Elytra at base very nearly twice as wide as the prothorax, a little more than three times as long, two-thirds longer than wide ; sides straight and parallel to the middle, then narrowly parabolic, the sides in apical third strongly convergent and nearly straight ; striae fine, completely concealed by the large scales. Length 1.7-2.2 mm. ; width 0.7-0.9 mm. California (Majave) ; Arizona (Riverside). Mr. H. F. Wickham. Tliis species resembles seriatus, but is easily distingnishable by its still smaller subcylindrieal prothorax, and very large imbricated scales of the upper surface. It was taken in considerable abun- dance and I have before me eight specimens. 12 S. silaceus n. sp. — Narrowly oblong-oval, moderately convex, black, the legs dull rufo-piceons, the tarsi blackish ; vestiture consisting of moder- ately large, elongate-oval scales, extremely dense, widely overlapping, pale ochreous in coloi', feebly variegated with a slightly darker brown, finer and sparser in two wide approximate pronotal vittse, which are thereby darker in tint ; on the iinder surface whitish, broadly rounded and dense ; recurved setae stout but short and not very conspicuous. Head squamulose, the con- striction distinct ; beak in the male short, stout, dull, densely jiunctate, squamulose except beyond the antennae, very feebly arcuate, subeqnal in length to the head and prothorax, with the antennae inserted at apical third, in the female slightly longer, more slender and arcuate, smooth, polished and minutely, sparsely punctate in apical two-fifths, slightly longer than the head and prothorax and just visibly more than one-half as long as the elytra, with the antennae inserted at apical two-fifths ; basal fasciculate tufts rather dis- tinct ; antennae short, the second funicular joint but slightly longer than the third.

Length 1.4-1.7 mm. ; width 0.6-0,7 mm. Arizona. The live specimens in my cabinet display scarcely any variation. This is one of the most minute species of the genus, and will be easily known by the characters given. 13 S, spiircilS n. sp. — Rather broadly oblong-oval, moderately convex, black, the beak piceous ; legs rufous, blackish near the base, the tarsi black- ish ; vestiture of the upper surface consisting of extremely dense, widely imbricated, pale ochreous-yellow scales, rather small in size, uniformly dense throughout the pronotum, scarcely visibly uneven in coloration on the elytra, nearly similar beneath and equally dense; recurved setae stout, rather abiin- dant but concolorous and not very conspicuous. Head densely squamose, the constriction rather ffeeble ; beak in the female slender, distinctly, evenly arcuate, rather densely squamose in basal half but nude, polished, minutely, sparsely punctate thence to the apex, about three-fifths as long as the elytra ; antennae inserted at apical two-fifths, the second funicular joint but slightly longer than the third. ProtJiorax very nearly as long as wide, the sides broadly, feebly arcuate and gradually convergent, nearly straight and not perceptibly constricted anteriorly to the apex, the latter three- fourths as wide as the base; sculpture entirely concealed by the dense even crust of scales. Elytra at base fully one-half wider than the prothorax, three times as long, one-lialf longer than wide, the sides straight and parallel in basal half, then angulato-para- bolic ; striaj indicated only by narrow and rather ill-defined partings of the vestiture. Length 1.9 mm. ; width 0.85 mm. Texas. The single female l)efore me represents a species somewhat allied to silaceus, but decidedly different in its shorter, broader form, wider elytra, longer beak in the female and uniformly, densely covered pronotum. 14 S. vestitus Lee— Proc. Am. Phil. Soc, XV, p. 172. Rather narrowly oblong-oval, convex, blackish, the beak, antennae, legs and elytra rufo-testaceous, the latter with the suture and base clouded with piceous; vestiture consisting of rather small elongate- oval yellowish scales, moderately dense, sometimes quite sparse, not mottled, intermixed with distinct recurved seta\ Beak in the male short, stout, feebly arcuate, tapering, smooth and nude toward apex, scarcely longer than the head and prothorax, with the antennas in- serted at apical two-fifths, in the female much longer, smooth, cylin- drical, subglabrous and subimpunctate, slightly squamose toward base, evenly, moderately arcuate, rather more than one-half as long 394 Coleopterological Notices, IV. as the elytra, with the antenna? inserted distinctly behind the mid- dle; antennae slender, the second funicular joint fully as long as the next two in the female, slightly shorter in the male. Prothorax nearly as long as wide, evenly rounded at the sides, feebly narrowed but scarcely at all constricted toward apex. Elytra at base one-half wider than the prothorax, a little more than three times as long, parallel in basal half, the sides broadly, feebly but distinctly con- stricted before the apex. Length l.T-2.2 mm.; width O.T-1.0 mm. Kansas, Colorado and Montana. The tarsal claws in this distinct and easily recognizable species are unusually long and divergent but connate at base. 15 S. sparsiis n. sp. — Oblong-oval, convex, deep black throughout, the vestiture of the upper surface consisting of small elongate-oval whitish scales, uniform throughout and very sparsely scattered over the elytra, the strire in- dicated by partings which are wider than the grooves, rather denser, and wider beneath on the sterna and their side-pieces. Head subglabrous, aluta- ceous, finely but strongly reticulate ; transverse constriction well marked, fine ; beak in the male rather long, evenly cylindrical and somewhat thick through- out, feebly, evenly arcuate, sparsely but strongly punctate and subglabrous in apical half, finely and sparsely squamulose and more opaque toward base with the two fasciculate basal tufts small, distinctly longer than the head and prothorax and one-half as long as the elytra ; antennae inserted at the middle, the second funicular joint subequal to the next two. Prothorax slightly wider than long, the sides feebly convergent, broadly, evenly arcuate nearly to the apex, the subapical constriction not large but distinct ; apex three-fourths as wide as the base ; disk not very coarsely but deeply, closely and evenly punc- tate, the punctures not much obscured by the vestiture. Elytra at base one- half wider than the prothorax, three times as long, fully one-half longer than wide, parallel and nearly straight at the sides in basal half, then gradually ogival, not constricted before tlie apex ; striae fine, deep, consisting of narrow approximate linear punctures near the sides. Tarsal claws rather long, stout, pointed, distinctly divergent but completely connate at base. Length 2.5 mm. ; width 1.1 mm. Colorado. The single specimen represents a species allied to sordidua and griseus, but differs in the small, widely-scattered scales and black legs. From the male of so?rlidus it differs in its much longer, non- tapering, sparsely squamulose beak, with the antennae inserted at the middle. The male of griseus I have not at hand, but the female differs from the type of sparsus in its very much larger and more elongate prothoi-ax. Coleopterologiccil Notices, IV. 395 16 S. pleiiralis n. sp. — Robust, oblong-oval, convex, black, the legs red with the tarsi darker, extremely densely clothed above with large scales, ab- ruptly white in lateral sixth of the pronotum and more than lateral fourth of the elytra, elsewhere above dark red-brown, smaller, whitish, very dense beneath ; brown scales above easily denuded, the white more persistent. Head finely granulate, obscurely areolate ; transverse impression feeble ; beak rather slender, distinctly arcuate, strongly punctured throughout, opaque toward base, squamulose, the scales suberect laterally toward base, equal in length to the head and prothorax ; antennae inserted a little beyond the middle, the basal joint of the funicle about as long as the next two, second rather more than one-half longer than the third. Prothorax very nearly as long as wide ; sides parallel, broadly, evenly arcuate, convergent and distinctly constricted very near the apex, the latter two-thirds as wide as the base ; disk where denuded strongly, rather closely, evenly perferato-punctate, the interspaces narrow but smooth and polished. Elytra at base one-third wider than the prothorax, two and one-half times as long, not more than one-third longer than wide, nearly straight and parallel at the sides in basal half, then nar- rowly parabolic, with the convergent sides nearly straight ; strise fine, deep toward the middle when denuded. Length 2.0 mm. ; width 1.0 mm. Arizona. A single specimen which is probably a female ; the second ventral segment is minutely but quite distinctly angulated posteriorly at the sides. 17 S. olbtectus Lee— Proc. Am. Phil. Soc, XV, p. 171. Oblong-oval, convex, deep black throughout, polished when de- nuded, the pronotum then strongly, closely, evenly punctured ; integuments densely clothed with rather large, deeply and coarsely strigose, elongate-oval scales, widely overlapping longitudinally on the elytra, dark brown in color, very feebly and indefinitely mottled with cinereous toward the sides ; recurved setae as usual. Beak in the male rather thick, feebly arcuate, densely squamose, opaque, scarcely longer than the prothorax, the antennae inserted near apical two-fifths, in the female slightly thinner, nearly straight, as long- as the head and prothorax, otherwise similar to that of the male, the antennte inserted just visibly beyond the middle; basal squamu- lose tufts very prominent ; antennae moderate, the basal joint of the funicle subequal to the next three, second one-half longer than the third. Prothorax large and long, fully as long as wide, the sides parallel and broadly arcuate, becoming convergent and strongly constricted toward apex, the latter three-fourths as wide as the base. Elytra at base not more than one-third wider than the prothorax, Annals N. Y. Acad. Sgi., VI, Aug. 1892.— 27 396 Coleopterological Notices, IV. scarcely more than twice as long-; sides parallel and straight in basal half, then narrowly parabolic ; striae fine, deep, strongly punc- tured laterally. Length 1.8-2.8 mm.; width 0.75-1.2 mm. California (Los Angeles and San Diego). A very distinct spe- cies, easily identifiable by its large elongate prothorax. The vesti- ture is very easily abraded, and, out of a large series which I took at San Diego, there is scarcely a specimen having more than a few scattered scales on the upper surface. One specimen in my cabinet is labeled "Arizona." 18 S. sordidus Lee— Proc. Am. Phil. Soc, XV, p. 173. Oblong-oval, convex, black, the legs dull rufous; integuments densely clothed with moderately large, broadly oval scales, uniform in coloration, ochreous to cinereous on the upper surface, whiter beneath ; recurved setse small and distant. Beak in the male short, thick, nearly straight, feebly tapering from base to apex, coarsely, densely squamose except near the apex, coarsely punctate, scarcely longer than the head and prothorax, with the antennae inserted a little beyond the middle, in the female long, very slender, equally, evenly cylindrical and feebly arcuate throughout, smooth, finely, sparsely punctate, squamose only very near the base, one-half longer than the head and prothorax and scarcely visibly shorter than the elytra, with the antennae inserted somewhat behind basal two-fifths ; antennae slender, the second funicular joint slightly shorter than the next two. Prothorax distinctly narrowed from base to apex, broadly, rather strongly rounded at the sides, deeply constricted behind the apex, the latter three-fourths as wide as the base ; disk convex, slightly wider than long. Elytra at base one-fourth to one-third wider than the prothorax, two and one-half times as long. Length 2.1-2.4 mm.; width 0.8-1.05 mm. Texas. A rather small species, allied completely in the structure of the beak, both in the male and female, to constrictus (Desmoris). The original description is greatly in error in stating that the tarsal claws are not connate ; they are rather long and completely connate in basal fourth. The head behind the transverse groove is abruptly and completely glabrous, highly polished, sometimes with merely a very feeble transversely wavy strigilation, while in griseus it is dull and strongly, coarsely reticulate. 19 S. constrictus Say. — Journ. Ac. Nat. Sci., Phila., Ill, p. 313 ; Ed. Lee. II, p. 17G (Rhyiichsenus) ; Lee. : Proc. Ani. Phil. Soc, XV, p. 1G8 (Desmoris). Coleopterological Notices, IV. 397 Oblong'-ov^al, black, densely and uniformly clothed with elongate- oval appressed scales, cinereous to ochreous in color, each interval of the elytra with a single series of short robust recurved squamules. This species is either one of the most variable of curculionides in structural peculiarities affecting parts of the body referred to by LeConte for generic characters, or the large series before me is made up of closely allied species which can only be differentiated by the collection of abundant material from carefully recorded localities. I will at present simply describe certain modifications noticed in three female types taken in Iowa, New Mexico and northern California respectively : 1 — Beak fully one-half as long- as the body, extremely slender; basal joint of the funicle barely as long as the next two, the second fully three-fourths as long as the first; legs, tarsi and antennae pale rufous; beak rufescent. 2 — Beak very long, nearly two-thirds as long as the body, thicker ; basal joint of the funicle fully as long as the next three ; second one- half as long as the first; legs, antennae and beak throughout l)lack. 3 — Beak much shorter, stouter, two-fifths as long as the body ; basal joint of funicle longer than the next two; legs rufous, the tarsi darker; beak and antenna blackish, the club paler. In the male the beak is very much shorter and thicker, densely punctate, squaraose, with the antennae inserted just beyond the middle. Length 2.2-4.0 mm. ; width 1.0-1.8 mm. Iowa to Arizona, northern California. A very abundant species; the smallest and largest in my series of thirty or more specimens are both females. 20 S. griseilS Lee. — Proc. Am. Phil. Soc, XV, p. 171. Narrowly oblong-oval, convex, black, the legs dark riifo-piceous ; scales moderate in size, broadly oval, dark brownish and paler, dense but not overlapping on the upper surface, white and very dense beneath. Beak in the female very slender, cylindrical, just visibly bent, much longer than the head and prothorax and nearly tw^o- thirds as long as the elytra, punctured, opaque and squamulose toward base, smooth and with small subelongate erosions toward apex ; antennae inserted slightly behind the middle, short, the scape not quite attaining the eye ; second funicular joint but slightly longer than the third. Prothorax large, fully as long as wide, sub- parallel and broadly, evenly and strongly arcuate at the sides, rather 898 Coleopterological Notices, IV. strongly but gradually narrowed and broadly, feebly constricted toward the apex, the latter three-fourths as wide as the base ; disk convex, rather coarsely, deeply, densely punctate, widest behind the middle. Elytra at base scarcely more than one-fourth wider than the prothorax, just visibly more than twice as long, one-half longer than wide, parallel in basal half, then regularly, acutely ogival, not constricted before the apex ; striae deep but not very coarse. Tarsal claws rather small, nearly parallel, connate toward base. Length 2.3 mm.; width 0.9 mm. Texas. Resembles scapalis, except in the color and disposition of the scales and in its very much smaller size. 21 S. COlinivens n. sp. — Oblong-oval, moderately stout ami convex, piceous-black, the beak, antennae and legs throughout rufous ; vestiture very dense and uniform, consisting of moderately large, coarsely strigose, grayish- white scales, with intermixed recurved setae, concolorous, dense and but slightly smaller on the under surface. Head not very densely squamulose, the constriction feeble ; beak in the female very slender, gradually, just visi- bly thicker from the antennse to the base, feebly, evenly arcuate, polished and impunctate in apical half, thence gradually more punctured, opaque and sparsely, finely squamulose to the base, much longer than the head and pro- thorax and about three-fifths as long as the elytra, the basal tufts composed of long slender squamules ; antennae inserted at the middle, the second funi- cular joint three-fourths as long as the first and about equal to the next two. Prothorax very nearly as long as wide, the sides broadly arcuate, gradually convergent, broadly and just visibly sinuate to the apex, the latter scarcely more than two-thirds as wide as the base ; disk strongly, densely punctate and subrugose, the punctures tending strongly to coalesce. Elytra at base two-fifths wider than the prothorax, not quite three times as long, slightly less than one-half longer than wide, the sides straight and parallel in basal three-fifths, the apex evenly ogival ; striae indicated by coarse partings of the vestiture. Legs rather loaig and decidedly slender ; tarsal claws as usual. Length 2.3 mm. ; width 1.0 mm. Missouri (St. Louis). Mr. Hugo Soltau. A moderately small species, without any striking features, but evidently different from any other here brought to notice. It ap- pears to combine certain of the characteristics of sordiclus and Jiavi- cans, but differs from the former in its much shorter beak and medial antennte in the female, and from the latter in the disposition of the vestiture. It is represented by a single female specimen. 22 S. sei-iatus Lee— Proc. Am. Phil. Soc, XV, p. 172. Oblong, rather convex, piceous, clothed densely with elongate- oval scales, 3'ellowish and confusedly, feebly nubilate with white Coleopterological Notices, IV. 399 above, especially at the base of the third interval, uneven in distri- bution near the suture, very dense and white throughout beneath ; upper surface with the usual stout recurved sette not especially prominent. Beak in the female rather long, punctate, decidedly squamulose except beyond the antennas, very feebly, evenly arcuate and about three-fifths as long as the elytra ; antennae inserted at the middle, rather short, the second funicular joint but very slightly longer than the third. Prothorax small, as long as wide, the sides rounded, feebly convergent and quite distinctly constricted ante- riorly, densely and confusedly squamose and setose. Elytra at base nearly one-half wider than the prothorax, about three times as long, one-half longer than wide ; sides parallel and straight to the middle, then gradually narrowly parabolic ; striae fine, with large elongate punctures toward the sides ; vestiture generally more denuded toward the middle. Length 1.15-2.5 mm.; width O.T-1.0 mm. California (Mariposa) — Cab. LeConte ; Arizona and Texas. A small species, distinguishable by its small elongate prothorax and rather long beak, which is punctured and more or less squamulose almost throughout, even in the female. In the male it is short, very densely squamose and hispid, as long as the head and prothorax and with the antennae inserted near apical third. It was taken in great abundance by Mr. Dunn at Benson, Arizona. The Texan form identified by LeConte as cornicidatus, belongs to this species. 23 S. fidlicialis n. sp. — Oblong-oval, convex, rather shining when de- nuded, black, the legs rufous, blackish at base ; elytra broadly pale and rufes- cent toward the sides ; vestiture of the pronotum dense and squamiform at the sides, becoming sparser and fine toward the middle, that of the elytra dense and nearly uniform, consisting of elongate-oval, pointed, yellowish scales, more condensed and coarser in wavy subtransverse areas ; on the under sur- face yellowish-white, the scales smaller and more rounded, dense. Head finely squamulose, the constriction deep, the two corniculate tufts long and conspicu- ous ; beak in the male moderately tliick, even throughout, not tapering, dull, punctate, deeply furrowed and feebly arcuate toward apex, a little longer than the head and prothorax, nearly one-half as long as the elytra ; antennae inserted at apical third, the second funicular joint but slightly longer than the third. Prothorax very nearly as long as wide, the sides broadly, evenly, not very strongly arcuate, moderately convergent, broadly and feebly sinuate toward apex ; disk convex, rather coarsely, deeply, evenly and densely punc- tate, the punctures rounded and all distinct. Elytra at base scarcely two- fifths wider than the prothorax, two and one-half times as long, more than one-half longer than wide, evenly elongate-ogival throughout, the sides not 400 Coleopterological Notices, IV. becoming quite parallel toward base ; strife fine, deep and abrupt toward the suture. Length 2.5 mm. ; width 1.1 mm. Iowa. The only species with Avhich this can be compared are Jiavicans and scapalis, but it differs greatly from the former in its longer prothorax, Avith even circular and distinct punctures and slender sparse squamules toAvard the middle ; in Jiavicans the pronotum is coarsely, densely squamose throughout, and the sculpture consists of more or less pronounced oblique furrows, caused by the coales- cence of the punctures. Scapalis is a much larger, stouter species, with different color and structure of the vestiture. 24 S. scapalis Lee. — Proc. Am. Phil. Soc, XV, p. 168 (Desmoris). Oval, convex, black; legs dull-rufous, blackish toward base; ves- titure consisting of ochreous-yellow scales, moderately dense and forming subtransversely wavy condensed areas on the elytra. In the male the beak is densely punctured, moderately slender, rather longer than the head and prothorax, the antennae inserted slightly beyond the middle, the basal joint of the funicle equal to the next two ; in the female it is slightly longer but scarcely more slender, smoother, almost straight, the antennae inserted scarcely at all be- hind the middle, the basal joint of the funicle distinctly longer than the next two, the club longer and narrower. Prothorax very nearly as long as wide, widest behind the middle ; sides broadly arcuate, convergent and sinuate toward apex ; disk rather coarsely, deeply, densely punctate. Elytra at base about one-third wider than the prothorax, scarcely more than twice as long, the sides straight and parallel in basal third, then gradually ogival; striae narrow, deep, abrupt, obscurely punctate at the bottom. Length 3. '7-4. 2 mm.; width 1.1-2.0 mm. Illinois. One of the largest species of the genus, greatly resem- bling Jiavicans in the color and disposition of the elytral vestiture, but very different in its more elongate prothorax. It differs radi- cally from constrictus, with which it has been associated, in the loes pronounced sexual differences in the beak, and in the peculiar arrangement of the elytral scales. 25 S. flaTicailS Lee. — Proc. Ara. Phil. Soc, XV, p. 171. Oblong-oval, rather stout, convex, blackish, with the legs paler, densely clothed with oval scales, ochreous to white in color, strongly Coleopterological Notices, IV. 401 mottled on the elytra and generally with a short whitish line at the base of the third interval. Beak in the male one-half as long- as the elytra, very feebly arcuate, punctured and squamose, the antenntt inserted a little beyond the middle, the second joint of the funicle slightly longer than the third ; in the female but very slightly longer, more slender, smooth, squamulose toward base, very feebly arcuate, the antennae inserted slightly behind the middle, the second funicular joint as long as the next two. Prothorax slightly wider than long, the sides convergent but not noticeably constricted toward apex, the latter two-thirds as wide as the base. Elytra at base two-fifths wider than the prothorax, between two and three times as long, one-half longer than wide, the sides nearly straight and parallel in basal half; striae fine. Length 2.3-3.0 mm.; width 1.0-1.5 mm. Texas, Dakota and Indiana. A rather common species, above the average in point of size, and easily recognizable by the peculiar condensations of larger and paler scales on the elytra, the vestiture of which is, however, very dense throughout. In one male speci- men the beak is not longer than the head and prothorax, and very much less than one-half as long as the elytra. 26 S. COngestllS n. sp. — Oval, convex, pale rufo-testaceous througliout, the elytral suture narrowly picescent ; vestiture sparse and uneven, yellowish- white, consisting of fine slender sparse squamules, which become larger and pquamiform in the condensed spots, of which there are several on the prono- tum ; elytra with large subtransverse wavy condensed areas ; metasternum and abdomen sparsely clothed with very fine elongate squamules, the met- episterna densely squamose. Head with a few fine squamules anteriorly ; constriction evident ; beak in the male moderately thick, not tapering, feebly bent toward apex, opaque, sparsely squamulose, the basal tufts not well developed, longer than the head and prothorax and more than one-half as long as the elytra ; antennse inserted rather beyond apical third, slender, the second funicular joint scarcely longer than the third, both elongate and one- half longer than the fourth. Prothorax but slightly wider than long, sub- parallel and strongly, evenly arcuate at the sides, feebly narrowed and finely distinctly constricted near the apex ; disk convex, rather coarsely, deeply and closely punctate, the punctures circular. Elytra at base one-third wider than the disk of the pronotum, two and one-half times as long, two-fifths longer than wide, ogival, the sides gradually becoming almost parallel and feebly arcuate toward base; strise distinct. Length 2.0-2.2 mm. ; width 1.0-1.1.5 mm. Colorado; District of Columbia. There is no species with which this can be regarded as closely allied. It somewhat suggests tychioides, but the pronotal sculpture is of an entirely different order, and it differs from any other form 402 Coleopterological Notices, IV. known to me in the elongate third joint of the antennae. The speci- men from the District of Columbia exactly resembles the Colorado type, but has the beak still longer, two-thirds as long as the elytra, smoother, more evenly arcuate, with the antenna3 inserted at apical two-fifths; it is without doubt the female. 27 S. tycliioides Lee— Proc. Am. Phil. Soc, XV, p. 171. Oval, convex, shining, black, the elytra with a very feeble sub- lateral rufescent vitta ; legs red, black near the coxae ; tarsi blackish ; vestiture of the upper surface sparse and uneven, very fine and sparse on the pronotum, yellowish and condensed in uneven sub- transverse spots of coarse scales on the elytra, the interspaces thinly sprinkled with fine short squamules ; under surface very densely clothed throughout with small rounded yellowish-white scales. Beak thick and gibbous toward base, strongly tapering, thin and smooth toward apex, evenly, rather feebly arcuate, slightly longer than the head and prothorax ; antenna3 inserted slightly beyond the middle, the second funicular joint nearly as long as the next two. Prothorax rather large, strongly convex, slightly wider than long, strongly rounded at the sides, the latter moderately convergent, broadly and just visibly sinuate near the apex; punctures reniform or lunate, small, rather sparse, becoming larger and rugose laterally, without trace of median line; interspaces polished, not reticulate. Elytra at base one-fourth wider than the prothorax, a little more than twice as long, one-third longer than wide, elongate-ogival, becoming almost parallel near the base. Length 2.2 mm. ; width 1.1 mm. Kansas. I am not certain of the sex of the single example before me, but the thick, strongly tapering beak would appear to indicate the male. 28 S. sagittatUS n. sp. — Oblong-oval, convex, feebly shining, black, the antennae piceous witli the club paler ; legs and tarsi pale rufous, coxae darker ; elytra black, with a broad pale rufous and oblique vitta on each from the humeri to the apex ; vestiture almost entirely denuded in the type, but appa- rently sparse and uneven as in tychioides. Head dull, the constriction moder- ately strong ; beak thick, dull, equal in diameter and extremely feebly evenly arcuate throughout, a little longer than the head and prothorax ; antennae inserted at apical third, the second funicular joint but slightly longer than the third. Prothorax moderate in size, convex, quite distinctly wider than long, the sides evenly, rather strongly rounded, convergent but scarcely con- stricted anteriorly ; disk dull, the sculpture fine, not very deep, extremely Coleopterological Notices, IV. 403 dense and peculiar, consisting of long oblique uneven eroded channels, which are evidently formed by the coalescence of reniform punctures of the tijrhioides type, but also with an even median line, entirely impunctate and finely granulato-reticulate. Elytra at base one-third wider than the prothorax, fully two and one-half times as long, one-half longer than wide, ogival in apical half, the sides thence straight and parallel to the base ; humeri right, promi- nent but narrowly rounded ; strise deep, punctate toward the sides. Length 2.0 mm. ; width 0.85 mm. Rhode Island. This species, while allied to tycMoides and sculpticoUis, is dis- tinct from both in the narrow granulose clearly limited impunctate median line of the pronotiim ; the latter is larger than in sculpti- coUis, but smaller than in tijchioides. It is represented by a single male example. 29 S. SCIlIpticollis n. sp. — Narrowly oval, convex, feebly shining, black, the antennfe piceous, the legs red, darker near the coxae, the tarsi piceous ; elytra bright rufous, the suture broadly, suffusedly blackish ; vesti- ture sparse and uneven, fine and sparse at the sides of the prothorax, con- fusedly mottled with condensed areas of larger yellowish-white scales and small si^arse slender squamules on the elytra ; under surface clothed sparsely with small elongate squamules, very dense on the met-episterna. Head dull, subglabrous ; constriction very deep ; beak in the male thick, dull, punctate, sparsely squamulose, evenly cylindrical, not tapering, evenly, feebly arcuate, distinctly longer than the head and prothorax, with the autennse inserted just behind apical third, in the female slightly longer and smoother, evenly cylindrical, evenly, moderately arcuate, nearly three-fifths as long as the elytra, with the antennae inserted at apical two-fifths ; antennae moderate, the second funicular joint much shorter than the next two. Prothorax small, slightly wider than long, convex, strongly, evenly rounded at the sides, feebly narrowed but scarcely at all constricted near the apex, very deeply, densely sculptured, the sculpture consisting of moderately small reniform punctures, close-set and often coalescent, with the narrow interspaces more or less punc- tulate, without trace of median line. Elytra at base one-half wider than the prothorax, fully two and one-half times as long, elongate-ogival, the sides becoming parallel and nearly straight in basal half; striae distinct, obsoletely punctate. Length 2.1-2.25 mm.; width 0.9-1.0 mm. Virginia ; Indiana ; Texas. A common species, allied to tychioides, but abundantly distinct in its much smaller, more coarsely and densely sculptured protho- rax and very different beak, also in the shorter second funicular joint, and sparser and narrow scales of the metasternum. 30 S. ilistaljilis n. sp. — Oblong-oval, stout, convex, intense black, polished when denuded, the pronotum feebly alutaceous, with the punctures 404 Coleopterological Notices, IV. rather small, not very deep and slightly oval, the interspaces finely piinctu- late ; scales whitish, narrowly oval, dense ; legs bright rufous, the tarsi darker. Head minutely punctate ; constriction strong ; beak rather thick, feebly arcuate, densely punctate in basal half, the apical regions sparsely so and shining, equal in length to the head and prothorax ; antennje inserted slightly beyond the middle, the basal joint of the funicle not quite as long as the next three, second one-half longer than the third. Prothorax large, not quite as long as wide, the sides rounded before the middle, thence feebly con- vergent and nearly straight to the base, very deeply constricted at some dis- tance behind the apex, the latter tubulate and barely three-fourths as wide as the base ; disk widest before the middle. Elytra at base two-fifths wider than the prothorax, two and one-half times as long, not quite one-half longer than wide, the sides straight and parallel in basal half, then narrowly parabolic ; strise fine, deep, scarcely at all impressed and with elongate narrow punctures laterally. Length 2.0 mm. ; width 0.9 mm. California (Napa Co.). The single specimen, which I took at Suscol Station, is almost entirely denuded above, with only a small spot of white scales near the middle of each elytron and others yellowish in color scattered thence to the apex ; the two spots are unsymmetrical and therefore simply remnants of the vestiture ; the specimen is probably a female. The beak is sparsely and rather finely setulose, with a small abrupt tuft of white squamules above each eye. This species is easily separable from obtectus by its shorter, more obese form and red legs, from cinereus by its large prothorax, and from both by the ditterent sculpture of the pronotum. 31 S. cinereus Mots. — Bull. Mosc, 1845, II, p. 37(3 ; Lee. : Proc. Am. Phil. Soc, XV, p. 173. Oblong-oval, convex, black throughout, the legs rarely with a feeble piceous tinge ; integuments densely clothed with elongate- oval dark brown and cinereous scales, confusedly and not conspicu- ously mottled on the elytra, the surface polished black when de- nuded, the pronotum rather finely but very deeply and closely punc- tate, the punctures not in actual contact, perforate. Beak differing scarcely at all in the sexes, short, thick, strongly, densely punctate, sparsely squamulose, with two erect tufts at base, very feebly arcuate and but very slightly longer than the head and prothorax ; antennae inserted near apical third in the male and two-fifths in the female, the basal joint of the funicle fully as long as the next three, second barely longer than the third. Prothorax but slightl}" wider than long, the sides broadly arcuate, broadly, feebly constricted behind Coleopterological Notices, IV. 405 the apex, the latter scarcely three-fourths as wide as the base. Elytra at base one-half wider than the prothorax, very nearly three times as long-, one-half to three-fifths longer than wide, straight and parallel at the sides in basal half to three-fifths; striae fine, deep, distinctly punctured toward the sides. Length 2.1-2.7 mm.; width 0.9-1.2 mm. California (San Francisco), abundant. The commonest species of the middle coast regions of California, and easily known by the characters given. I cannot perceive that the elytra are notably elongate in this species, as remarked by LeConte, but the very feeble sexual difference in the beak is a distinguishing character. 32 S. apionides n. sp. — Narrowly oblong-oval, convex, deep black throughout the body, legs and antennae ; vestiture sparse, consisting of small remote setiform squamules on the elytra, with small sparse condensed spots of wider white scales, the latter also more abundant on the pronotum toward the sides ; under surface sparsely and unevenly squamose. Head finely granu- lato-reticulate, the transverse impression feeble but distinct ; beak in tlie male short, thick, feebly arcuate, dull and granulose, punctate, sparsely setulose, not fasciculate at base, very slightly longer than the head and prothorax, with the antennae inserted just beyond the middle, in the female nearly similar, slightly longer, scarcely thinner. or more arcuate, smoother and more shining tliroughout, distinctly longer than the head and prothorax and fully one-half as long as the elytra, with the antennae inserted at the middle ; antennae moderate, the second funicular joint but very slightly longer than the third. Prothorax slightly wider than long, convex, the sides broadly, evenly arcuate, becoming more convergent and nearly straight near the apex, the latter three- fourths as wide as the base ; constriction almost completely obsolete ; punc- tures coarse, very deep, coalescent in threes or fours forming oblique sinuous lines. Elytra at base three-fifths wider than the prothorax, three times as long, three-fifths longer than wide, the sides nearly straight and parallel in basal half, the posterior half subacutely ogival ; striae rather fine, deep toward the suture but becoming simply series of coarse elongate punctures laterally. Length 1.6-1.75 mm. ; width 0.6.5-0.7 mm. North Carolina (Asheville). A very distinct minute species, represented in my cabinet by a single pair. It may be recognized by the sparse and uneven vesti- ture, and the coarse deep and peculiar sculpture of the pronotum. 33 S. perpusillllS n. sp. — Oblong-oval, convex, blackish- piceous ; legs rufous with the tarsi darker ; vestiture consisting of oval white scales, moder- ately large and generally not quite contiguous, and, on the pronotum, decidedly separated and varying in width ; recurved setae of the elytra fine distant and not conspicuous ; scales of the under surface small, rounded, white, very nar- 40*3 Coleopterological Notices, IV. rowly separated. Head scarcely shining, the frontal constriction very broad and feeble ; beak slender, cylindrical, smooth and extremely minutely, feebly punctulate in apical half, punctate and sparsely squamose toward base, dis- tinctly longer than the head and prothorax and nearly three-fifths as long as the elytra, evenly and distinctly arcuate ; antenna inserted at the middle, rather short, the second funicular joint but slightly shorter than the next two. Pi-othorax very nearly as long as wide, the sides broadly, evenly arcuate toward base, becoming slightly more convergent and nearly straight anteriorly, the constriction very feeble ; punctures small, shallow and not dense ; interspaces shining. Elytra at base one-half wider than the prothorax, two and two-thirds times as long, one-half longer than wide ; sides nearly straight, and parallel in basal half, then convergent, the apex acutely rounded ; striae fine but deep. Length 1.6 mm. ; width 0.6 mm. Florida. The unique type is a female and the species is not closely allied to any other known to me, being easily determinable by its small size and white scales, the latter close-set but generally not quite contiguous. 34 S. defl'icans n. sp. — Narrowly oblong-oval, convex, black, the legs dark rufous, the tarsi piceous ; upper surface clothed unevenly with moder- ately large oval whitish scales, generally denser, or at least more persistent, in a broad line from the humeri to the middle of each elytron ; stout recurved bristles short. Head dull, densely granulose ; transverse impression rather feeble; beak opaque, shining and finely, deeply sulcate in apical half, sparsely setulose toward base, densely so above the eyes, very feebly arcuate, stout, tapering, as long as the head and prothorax ; antennae inserted at apical two- fifths, the basal joint of the funicle rather robust, as long as the next three, second nearly one-half longer than the third. Prothorax very nearly as long as wide ; sides subparallel and broadly arcuate, convergent and very feebly constricted near the apex, the latter three-fourths as wide as the base ; disk subopaque, finely, rather feebly and moderately densely punctate, the inter- spaces minutely, very densely, deeply punctulate. Elytra at base not quite one-half wider than the prothorax, scarcely three times as long ; sides straiglit and parallel in basal three-fifths, then parabolically rounded ; striae fine but deep, the surface polished when denuded. Legs moderate, the tarsal claws very small, connate in basal half. Length 1.4-1.8 mm. ; width 0.6-0.7 mm. California (Lake and Monterey Cos.). The three specimens in my cabinet exhibit but slight variability and are of uncertain sex ; it is probable that the sexual differences in the beak are, however, very slight. This species is not closely allied to any other, and is easily distinguishable, among the Cali- forniau forms, by its minute stature. Coleopferological Notices, IV. 407 35 S. giljliirostris n. sp. — Stout and convex, oval, black, the legs except near the base rufous ; elytra pale rufous, narrowly blackish along the suture ; upper surface sparsely and unevenly clothed with yellowish scales and fine slender squamules, the former dense at the sides of the pronotum toward base and narrowly along the middle, and on the elytra in subtransverse uneven spots and fasciae ; under surface moderately densely squamose. Head polished, the constriction evident ; beak in the male moderately thick, very feebly, evenly arcuate, dull, densely punctate, strongly gibbous before the constric- tion, a little longer than the head and prothorax and about one-half as long as the elytra ; antennae inserted at apical two-fifths, the second funicular joint but slightly longer than the third. Prothorax moderately large, quite distinctly wider than long, the sides subparallel, broadly, rather strongly arcuate, con- vergent and broadly sinuate toward the apex, the latter three-fourths as wide as the base; disk convex, dull, very densely punctate, the punctures small, deep, lunate, the interspaces densely punctulate. Elytra at base not more than one-third wider than the prothorax, two and one-half times as long, about one-fourth longer than wide, just visibly wider behind the middle than at base, the sides straight, broadly parabolic in apical two-fifths, the strise deep and distinct. Length 1.9 mm. ; width 1.0 mm. Delaware. The single male represents a species allied somewhat to sculpfi- collis, but diifering in its larger, more densely sculptured pronotum, much shorter elytra, gibbous beak and different vestiture, the sides of the pronotum being simply sparsely, finely squamulose, and the third elytral interval conspicuously squamose at base in sculjyii- coUis. 3G S. sqiialidlis n. sp. — Stout, strongly convex, oval, black, the legs dark rufo-piceous ; vestiture of the upper surface dense, consisting of rather large imbricated scales, confusedly mottled whitish and piceous, the former generally predominating ; scales of the under surface very small, rounded, yellowish-white and extremely dense ; recurved setfe sparse and slender. Head feebly squamulose anteriorly, the constriction moderate ; beak in the male thick, very feebly arcuate, rough, densely punctate, sparsely hispid and dull almost throughout, much longer than the head and prothorax and one- half as long as the elytra, with the antennae inserted at apical third, in the female longer, more. slender and arcuate, finely, rather densely punctate but shining and nearly glabrous in apical half, nearly three-fourths as long as the elytra, with the antennae inserted at the middle ; basal tufts not well developed ; antennae rather slender, the second funicular joint three-fourths as long as the first and equal to the next two in the female, very little shorter in the male. Prothorax rather large and inflated, the sides strongly arcuate, convergent and rather strongly constricted near the apex, the latter not more than three-fifths as wide as the middle ; disk convex, rather coarsely, deeply, extremely densely punctured, one-fourth wider than long. Elytra at base not more than one-third wider than the prothorax, two and two-thirds times as 408 Coleopterological Notices, IV. long, one-fourth longer than wide, distinctly wider at the middle than at base, parabolic in apical half. Length 2.3-2.7 mm. ; width 1.2-1.4 mm. Pennsylvania ; District of Columbia ; Indiana. A common eastern form resembling ovipennis but much larger, with a relatively larger, more inflated prothorax, more elongate beak and longer second funicular joint. I found it labeled "amoe- ?iHs" in my cabinet, a mistake which may possibly be common ; amoeniis is a widely different species, with the prothorax scarcely perceptibly narrower than the base of the elytra. One specimen before me is labeled "Arizona," but perhaps erroneously. 37 S. OTipennis Lee. — Proc. Am. Phil. Soc, XV, p. 170. Oval, strongly convex, stout, black, the legs rufescent; scales of the upper surface moderately large, very dense, confusedly mottled with whitish and different shades of brown or piceous, the white scales usually more numerous and forming a distinct line at the base of the third interval. Beak in the male rather stout, densely squamosa, a little longer than the head and prothorax ; antennae inserted at apical two-fifths, the second funicular joint but slightly longer than the third. Prothorax small, slightly but quite distinctly wider than long, the sides evenly, rather strongly arcuate, conver- gent and very feebly constricted anteriorly, the apex fully three- fourths as wide as the base; disk densely, strongly punctate. Elytra at base nearly one-half wider than the prothorax, almost three times as long, barely one-fourth longer than wide, distinctly wider in the middle than at base, gradually, acutely ogival in apical half; striag indicated by coarse and uneven partings of the vestiture. Ijcngth 1.8-2.0 mm.; width 0.8-1.1 mm. Texas to Montana. The measurement given in the original description is slightly too great. PROmECOTARSUS n. gen. I have separated under this name three species closely allied to Smicronyx, but differing in the longer, more glabrous tarsi, having a smaller third joint, with the fourth joint very long and subequal in length to the entire remainder. In general appearance the species are more cylindrical than in Smicronyx, and more nearly resemble Endalus. The principal characters may be expressed as follows : — Body cylindrically convex, the elytra but very slightly wider than the pro- thorax, the vestiture dense, consisting of small, imbricated, almost completely Coleopferological Notices, IV. 409 non-stn'gose scales, with a series of recurved, subrecumbent setse on each strial interval. Beak constricted at base, the head nearly spherical, eyes as in Smicronyx. Prothorax constricted at apex, the ocular lobes more or less dis- tinct. Scutellum very small. Prosternum deeply sinnate at apex. Metaster- num as long as the first ventral segment. Abdomen flat, sutures two to four equally and feebly recurved at the sides, the second segment barely as long as the next two and not quite as long as the fifth. Legs, excepting tarsal structure, nearly as in Smicronyx. In this genus, which constitutes one of the intermediate forms connecting Smicronyx with the Hydronomi, the claws are long and generally widely divergent, but in one species become subparallel ; they may be described as connate very near the base, with the suture distinct. Promecotarsus is clearly, therefore, a transitional form but must be classed with Smicronyx, these two genera consti- tuting the group Smicronychi. The species may be easily known as follows : — Ungues widely divergent ; prothorax very nearly as long as wide ; ocular lobes not prominent. Prothorax abruj^tly, deeply constricted near the apex, the latter but slightly narrower than the base 1 iMaritinius Prothorax gradually more strongly narrowed and broadly, feebly constricted toward apex, the latter scarcely more than two-thirds as wide as the base. 2 dens IIS Ungues subparallel ; prothorax much wider than long, with the ocular lobes prominent 3 flimatus 1 P, maritilllllS n. sp. — Subcylindrical, convex, piceous, the legs feebly rnfesceut with tlie tarsi black ; vestiture very dense, pale, the broad recurved squamules very short and subrecumbent. Head shining, glabrous, the trans- verse groove deep ; beak in the male moderately thick, densely, rugosely punctate, sparsely squamulose, abruptly, strongly bent at the antennae, thence more shining and feebly tapering to the apex, fully as long as the head and prothorax ; antennae inserted at apical third, the funicle long, the basal joint as long as the next two, second almost as long as the third and fourth, outer joints a little longer than wide, not noticeably thicker, club very slender, fusi- form, the basal joint almost glabrous. Prothorax nearly one-fourth wider than long, parallel and broadly, evenly, rather strongly arcuate at the sides, deeply constricted behind the apex, the latter transversely truncate and but slightly narrower than the base ; disk feebly convex, very densely, not coarsely, sub- rugosely punctate. Elytra at base but slightly wider than the prothorax, rather more than twice as long, fully two-fifths longer than wide, the sides subparallel and nearly straight in basal three-fifths, the apex narrowly para- bolic ; striae deeply impressed. Legs^ moderate, the tarsi as long as the tibi;e. Length 2.0-2.2 mm. ; width 0.8-0.95 mm. 410 Coleopterological Notices, IV. California (San Diego). Mr. Chas. Fuchs. The three specimens in my cabinet are males, and the beak is probably much longer and more evenly arcuate in the female. This species somewhat resembles densus, but is smaller, narrower and differs greatly in the form of the prothorax, as well as in the some- what longer second joint of the antennal funicle. 2 P. densus n. sp. — Robust, subcylindrical, convex, black, extremely densely clothed with rather small, broadly oval, yellowish-white and uniform scales, which are widely overlapping, granulose in texture and not strigose, similar in structure and density on the under surface ; recurved setse distinct. Head glabrous, finely, strongly reticulate ; constriction fine, deep ; beak in the female slender, polished, exceedingly finely, remotely punctate, but thicker, dull and rugosely punctate near the base, nearly evenly and quite strongly arcuate, almost three-fifths as long as the elytra ; antennae inserted scarcely beyond basal third, rather long and slender, the second funicular joint about as long as the next two ; club moderately robust, very sparsely pubescent and shining toward base. Prothorax but slightly wider than long, the sides parallel and very feebly arcuate in basal two-thirds, then moderately conver- gent and broadly constricted to the apex, the latter rather more than two- thirds as wide as the base ; disk moderately convex, evenly, densely squamose, finely, very densely punctate throughout. Elytra at base but slightly more than one-fourth wider than the prothorax, not quite two and one-half times as long, one-half longer than wide, the sides parallel in basal three-fifths, then narrowly angulato-parabolic ; strise indicated by fine but sharply defined partings of the dense crust of scales. Legs somewhat stout, the tarsi long and slender, the third joint only moderately dilated, the last joint long ; claws long, divergent, connate at base. Length 2.5 mm. ; width 1.05 mm. Nebraska. Easily distinguishable by the dense and uniform crust of non- strigose imbricated scales and the subcylindrical form, as well as by the characters given in the table. 3 P. fuiuatus n. sp. — Moderately robust, convex, subcylindrical, black throughout, extremely densely clothed with a crust of widely overlapping, dark, yellowish-gray scales, uniform in color, very broad and excessively minutely, indistinctly strigilate ; recurved setse fine but distinct. Head gla- brous, minutely, feebly reticulate and rather strongly shining, the constriction tine but moderately deep ; beak in the male thick, evenly cylindrical, distinctly arcuate, moderately densely punctate, not quite as long as the head and pro- thorax, with the antennae inserted just beyond the middle, in the female a little more slender, evenly, distinctly arcuate, smooth and remotely punctulate except near the base, scarcely visibly longer than the head and prothorax, barely one-half as long as the elytra, with the antenna inserted at basal two- fifths ; antennae moderately slender, the second funicular joint as long as the Coleopto'ological Notices, IV. 411 next two ; club slender, gradually, acutely pointed, ratlier densely pubescent. Prothorax transverse, one-third to two-fifths wider than long, the sides parallel, broadly, evenly arcuate in basal two-thirds, then strongly convergent and deeply, abruptly constricted, the apex transverse between the very prominent ocular lobes; disk very densely squamose, the sculpture dense and subrugose when denuded. Elytra at base between one-third and one-fourth wider than the prothorax, fully three times as long, one-half longer than wide, the sides parallel and nearly straight in basal three-fifths ; striae indicated by clearly defined narrow partings of the vestiture. Length 2.2-2.3 mm. ; width 0.95 mm. Montana (Helena). Mr. H. F. Wickham. Closely allied to densus, but differing in its much shorter pro- thorax, shorter beak in the female, with the antennsB distinctly less basal, in its gray and not ochreous vestiture and in many other minor characters. It was taken in abundance, and the six speci- mens before me are very uniform in size. Tychiini. TYCHIUS Schcinh. In subdividing the comparatively few American representatives of this genus, I have made use of some characters which do not exist among the European species, or at least, which have apparently not been mentioned in systematic works. Our species may be readily divided into four subgeneric groups as follows: — Antennal funicle 7-jointed. Body more or less robust and oval, the elytral intervals entirely devoid of recurved setae I Body narrower, oblong ; elytral intervals with recurved semi-erect setae. ..II Antennal funicle 6-jointed. Body elongate-oval, with robust recurved setae, the entire facies almost as in group II; eyes large, very nearly circular IH Body much smaller, the species generally minute, with or without erect setae; eyes more or less transversely fusiform IV None of these divisions seems to correspond exactly with the European Miccotrogus, although I am not certain of the habitus of that subgenus, specimens sent to me by M. Desbrochers under the name M. jncirosti-is having the antennal funicle certainly 7-jointed. It can be confidently affirmed, however, that the structure of the funicle is without full generic significance in our species, for the reason that groups II and III agree so satisfactorily in all other structural features. At the same time, there is sufficient hete- rogeneity to warrant a division into subgenera on the lines above Annals N. Y. Acad. Sci., VI, Aug. 1892.— 28 412 Goleopterological Notices, IV. suggested. There is nothing to indicate that Miccotrogus possesses greater systematic value than any one of these American groups. The species may be easily recognized by the following charac- ters : — Subgenus I. Elytral vestiture narrowly vittate, often alternating fulvous and cinereous on the intervals, the strise broadly visible ; anterior tibiae of the male strongly, acutely toothed internally near the middle 1 liiieellllS Elytral vestiture nearly uniform in color, the striae indicated by fine and in- distinct i^artings ; anterior tibiie not dentate in the male. Beak thick, only feebly diminishing in diameter from base to apex. Body broadly oval, the scales very narrow and hair-like 2 sordidus Body more narrowly oval, the scales broader and more densely crowded. 3 tectus Beak thick at base, rapidly and finely attenuate toward apex ; elytral ves- titure mingled with a vei-y few widely scattered rounded scales toward apex 4 arator Subgenus II. Abdomen with sparse semi-erect setse, in addition to the dense squamosity. Setfe borne by the strial punctures of the elytra long semi-erect white and conspicuous. Prothorax less transverse, with a broad median vitta which is entirely clothed with large white imbricated scales ; setre throughout the body robust 5 SOltaili Prothorax strongly transverse, with a very fine white median line which contains no large non-strigose scales, except in the broader portion near the base; setse throughout longer and fine (J llirtellllS Setse borne by the strial punctures short, thicker, recumbent and incon- spicuous 7 aratus Abdomen densely squamose but without trace of setse ; scales of the elytra smaller and more densely imbricated along the suture than elsewhere. Beak very feebly narrowed toward apex ; prothorax a little less transverse, wider at tlie middle than at base ; elytra with many more setse than scales on the disk 8 seniisqaniosiis Beak rapidly and finely acuminate, thicker toward base ; body stouter ; sides of the prothorax parallel behind ; elytra with many more large whitish oval scales than setae 9 lailiellosiIS Subgenus III. Beak short, feebly tapering from base to apex ; elytra with large imbricated scales and very robust recurved fulvous setae 10 pi'Olixus Subgenus IV. Elytra without long erect bristles, although sometimes with abundant short strongly recurved seta;, which are not very conspicuous. Coleopterological Notices, IV. 413 Vestitiire finely and feebly variegated in color, and with a large sutnral spot of white imbricated scales behind the scutellum...ll Ta.riega.tllS Vestiture nearly uniform in color, the scales of the npper surface all narrow and elongate, the squamules borne by the strial punctures similar to the others or very nearly as wide. Elytral intervals each with a single nearly even series of narrow scales, fulvous to white in color 12 simplex Elytral intervals confusedly clothed with scales throughout their width. Elytral scales evenly but not very densely distributed, narrow and slender, oclireous-yellow in color, the middle scales of each interval semi-erect, especially toward apex 13 sibillioides Elytral scales broader and more closely recumbent, denser along the suture, more broadly so behind the middle 14 mica Elytra with stiff straight and strongly hispid erect or inclined setse. Elytra with large rounded or oval whitish scales, unevenly distributed. Elytral setse long and rather slender 15 setosus Elytral setse short, broad and scale-like 16 Sll1)fasciatlis Elytra with long slender white and fulvous decumbent squamules, entirely without rounded scales ; erect setse rather fine and much more numerous. 17 Iiispidiis The species of groups I and lY are generally taken in abundance when discovered, while those of II and III are apparently much less plentiful in individuals, or possibly less gregarious; they are also a little more closely allied among themselves, forming a more difficult study. I 1 T. lineellus Lee— Proc. Am. Phil. Soc, XV, p. 217. Broadly oval, strongly convex, rather densely clothed above with long, slender, coarsely strigose scales, which are variable in color, and, to some extent also, in distribution; in the best marked speci- mens they are subcupreous in two broad pronotal vittte, and on the alternate intervals of the elytra, elsewhere cinereous, but often cinereous throughout; on the under surface they are whitish, liroader, non-strigose and feathery in structure. The male has the beak short, abruptly tapering beyond the antennae, and the ante- rior tibiiB strongly, acutely toothed internally just beyond the middle; in the female the beak is longer, nearly straight, slender but abruptly thicker very near the base. Length 3.7-4.7 mm. ; width 1.7-2.2 mm. California (Siskiyou to San Diego). This is a common species throughout the State. 414 Coleopterological Notices, IV. 2 T. sordidus Leo.— Proc. Am. Phil. Soc, XV, p. 217. Robust, oval, convex, rather densely and uniformly clothed throughout with small slender scales, silvery gray to yellowish in color, and generally a little more condensed along the elytral suture ; erect set® completely wanting. Beak rather short, slender, straight, cylindrical, feebly tapering and slightly bent near the apex, barely as long as the prorhorax, finely, densely punctate, squamu- lose and more or less carinulate; antenuifi inserted at apical third, rather slender, the second funicular joint but slighth^ shorter than the first, slender, outer joints barely perceptibly wider, the club rather elongate, obliquely pointed at apex, rounded at base, almost equally trisected by two straight sutures. Prothorax slightly wider than long, the sides rapidly convergent from base to apex, broadly and evenly arcuate, constricted behind the apex, the latter scarcely more than one-third as wide as the base, the punctures circular, deep and dense. Elytra parallel, broadly rounded behind, one-fourth longer than wide, much wider than the prothorax and more than twice as long. Posterior femora feebly toothed. Length 4.0-4.7 mm. ; width 2.1-2.4 mm. Iowa and Illinois. Our largest species, sufficiently common and very readily recognizable by the characters given. The three speci- mens before me are probably males; in the female, the antennae are undoubtedly less apical. 3 T. tectus Lee— Proc. Am. PhiL Soc, XV, p. 217. Oblong-oval, convex, black, the antennae rufescent; body covered densely throughout with yellowish-white scales, whitish along the suture and middle of the pronotum and also toward the sides of the body ; scales rather wnde but parallel and subelongate, strigose. Beak evenly, moderately arcuate, subcylindrical, feebly tapering only very near the apex, finely, densely punctured throughout, densely squamulose but nude beyond the antennae, in the nuTle much shorter than the prothorax, with the antennas inserted near apical third, in the female much longer, as long as the prothorax, with the antennte inserted at the middle ; antennae slender, the basal joint of the funicle as long as the next three, second slightly longer than the third. Prothorax in the male two-fifths wuder than long, with the sides inflated before the middle and the apex less than one-half as wide as the base, in the female longer, one-fourth wider than long, with the sides ])arallel and nearly straight, the apex more than one- Coleopterological Notices, IV. 415 half as wide as the base. Elytra three-fifths longer than wide, scarcely wider than the disk of the prothorax in the male but dis- tinctly wider in the female, the sides subparallel in basal three- fifths; intervals without median line of squamules, the hairs of the strial punctures white and quite evident. Length 2.6-3.7 mm.; width 1.15-l.T mm. Colorado and Montana. Numerous specimens. In one female, not otherwise differing, the beak is deformed, the apical parts being swollen polished and impunctate, separated from the post-aniennal portion by a broad depression. The same deformity exists to a less marked degree in a male specimen, and the species seems to be peculiarly liable to this kind of rostal malformation. An extremely feeble transverse impression at the antennas is however apparently normal in some species, such as aratus Say. 4 T. arator Gyll.— Sch. Cure, III, p. 414; Lee. : Proc. Am. Phil. Soc , XV, p. 216. Oblong-oval; rather stout, convex, black, the legs piceous; an- tennas and apical parts of the ))eak rufo-testaceous ; body very densely clothed throughout with elongate dark ochreous scales, which are coarsely strigose, but intermixed with a few larger ones, toward the apex of the elytra, which are non-strigose in structure and rather paler in color ; intervals of the elytra without setas, the strial squamules distinct. Beak thick, tumid, densely punctured and squamulose behind, but very thin, glabrous, shining and sparsely punctured before, the point of antennal insertion, feebly arcuate, the thin apical portion straight, rather shorter than the prothorax in both sexes but a little longer in the female than in the male, the antennas inserted at the middle in the former and at apical two-fifths in the latter, with the basal joint of the funicle as long as the next two, the second two-thirds as long as the first. Prothorax two-fifths wider than long, the apex much loss than one-half as wide as the base. Elytra distinctly wider than the pro- thorax in both sexes, one-half longer than wide. Length 3.0-3.0 mm. ; width L4-L1 mm. Texas (Dallas)— Mr. Wickham ; Illinois— Cab. LeConte. This species is very isolated in all uf its characters, and cannot be com- pared with any other known to me. The hind femora are feebly toothed beneath. •il6 Coleoptej^ological Notices, IV. II. 5 T. SOltaui 11. sp. — Narrowly oblong-oval, moderately convex, black, the anteniife and tip of beak rufous; vestiture complex, consisting, on the beak, of slender semi-erect hispid s^uamules, recumbent behind an abrupt trans- verse line at the posterior margin of the eyes ; on the pronotutn, of slender dark fulvous squamules, partly erect and hispid, mingled, in a narrow line near the sides, with large whitish scales and with a broad median vitta, entirely composed of broad white scales ; on the elytra of large dense imbri- cated scales and serai-erect robust recurved setse, the latter disposed in single lines, the strial setae also distinct ; on the under surface of large oval white scales, generally concave along the middle, mingled with stout sparse setfe on the abdomen.

Elijtra barely one-fourth wider and two and one-half times longer than the prothorax, the sides becoming straight and parallel toward base, obtusely rounded at apex. Posterior femora rather slender, obtusely and feebly toothed. Length 2.6 mm. ; width 1.1 mm. W3'oming (Laramie). A rather narrow species, allied to hirfelhis and differing- in the broad vitta of white scales along the middle of the pronotum, the more elongate prothorax, shorter, much coarser semi-erect seta* above and on the abdomen, and in the generally narrower form of the body. The single male was taken by Mr. Hugo Soltau. 6 T. Itirtellus Lee— Proc. Am. Phil. Soc, XV, p. 218. Oblong-oval, moderately convex, piceous, the antenna^ and tip of beak rufous; vestiture complex, consisting of dark brownish-fulvous narrow strigose squamules on the pronotum, largely replaced toward the sides by oval pointed non-strigose scales, strongly imbricated and not quite recumbent, again darker along the middle of the flanks beneath, narrowly white along the median line, more broadly toward base ; on the elytra the vestiture consists of mode- rately large oval pointed pale brownish scales, strongly imbricated throughout, rather smaller, still denser and more ochreous on the sutural interval, the striae indicated by flne partings in the dense crust, with the white hairs borne by the strial punctures distinct ; Coleopterological Notices, IV. 417 intervals each with a single series of long stiff erect but rather fine seta3 ; on the under surface the scales are whitish and vei'y dense tlu'oughout, intermixed with long set^e on the abdomen.

Moutana. The type specimen, Avhich appears to be a male, agrees so thoroughly with the description of Say, that there can be little doubt of its representing the true arafus. It is unfortu- nate, however, that there should be two names in the same genus and within the same faunal limits which are mutually so similar. The term "olivaceous," applied by Say to the color of aratus, might have wide limits of meaning. 8 T. semisqnailiosus Lee. — Proc. Am. Phil. Soc, XV, p. 217. Narrowly oblong-oval, rather convex, piceous, the legs, antennae and tip of beak rufcscent ; vestiture complex, consisting of narrow elongate fulvous squamules on the pronotum, which become broad Avhite scales in the middle and at each side but only near the base, anteriorly there are also some widely scattered large brown scales; on the elytra the intervals are clothed throughout with stout re- curved and subrecumbent brown setae, among which there are very sparsel}^ strewn large dark gray-brown scales, the latter dense im- bricated and reddish along the sutural interval ; on the under surface the scales are whitish, elongate-oval and dense throughout. Beak in the male short, thick, not as long as the prothorax, feebly taper- ing from base to apex, densely squamulose except near the tip, the antennae inserted at apical two-fifths, the basal joint of the funicle very stout, not as long as the next three, second but slightly longer than the third, narrow at base, three to seven subequal, moniliform; club abrupt, oblong-oval.

Length 2.5 mm. ; width 1.0 mm. California. This species can be easily identified by the narrow form, sparse scales of the elytra except along the suture, and absence of erect ventral hairs. The large scales of the upper surface are, as usual, granulose in structure and not strigate. 9 T. lamellosus n. sp. — Rather broadly oblong-oval, convex, piceous, the tibise, antennae and tip of beak rufescent ; vestiture dense and varied, consisting on the pronotum of long narrow fulvous strigose squamules, gradu- ally intermixed toward the sides and almost replaced by large whitish scales, also narrowly along the middle, more broadly toward base ; on the elytra the non-strigose scales are very large, broad, ogival, pearly white in color, dense Coleopterological Notices, IV. 419 along the middle and lateral edge of each elytron, also dense and more yellow- ish along the sutural interval; recurved fulvous setse rather abundant; on the under surface the scales are elongate-oval, whitish and dense.

Allied to setosus, but easily distinguishable by the somewhat smaller scales of the upper surface, shorter and stouter erect seta?, and by the shorter, rather thicker beak and longer elytra. In both of these species the erect bristles are confined to the alternate inter- vals, except toward apex. Sexual differences are not evident, even in the length or structure of the beak. The third and fourth ven- tral sutures are almost obliterated by the dense crust of scales, but appear to be sinuate near the sides, although not flexed backward to any noticeable extent. Four specimens. 17 T. IlispidUS n. sp. — Oblong-oval, rather convex, piceous, elytra, except on the suture, more broadly toward base, legs, beak and antennae, rufous ; vestiture moderately dense, not very uneven, consisting, on the upper surface, of long slender squamules, subrecumbent, whitish and pale fulvous confusedly intermingled, evenly distributed over the pronotum and entire width of the elytral intervals, and without trace of large rounded scales ; all the elytral intervals throughout their length with single series of long erect bristling setse, whitish in color and rather widely spaced ; squamules of the strial punctures distinct, white ; under surface rather densely clothed with large oval whitish scales. Bead finely squamulose, the transverse impression subobsolete ; eyes transversely fusiform ; beak in the male rather stout, very feebly tapering and slightly arcuate throughout, squamulose except near the apex, about as long as the head and prothorax, with the antennae inserted just behind apical third; in the female very slightly longer, thick, squamulose and subinflated in basal half, very thin, glabrous and cylindrical in apical half, the antennae inserted at the middle ; antennfe rather short, the basal joint of the funicle subequal to the next three, second one-half longer than the third. Prothorax one-fourth wider than long, the sides very feebly arcuate, slightly constricted behind the apex, the latter two-thirds as wide as the base. Elytra two-fifths wider than the prothorax and very nearly three times as long, about one-half longer than wide, suboval, the sides parallel and just visibly arcuate, gradually con- vergent and more rounded toward apex, the latter less obtuse than usual. Posterior femora unarmed. Length 1.4-1.8 mm. ; width 0.65-0.8 mm. Arizona (Santa Rita Mts.). Mr. H. F. Wickham. This inconspicuous species is somewhat allied to setosus and sub- fasciatus, but only in possessing erect bristling setae, otherwise it differs greatly in the entire absence of large rounded scales on the upper surface, and in the strongly marked sexual characters of the beak, the latter, somewhat unusually, being more rapidly and Coleoj)terological Notices, IV. 425 strongly inflated toward base in the female than in the male, nearly as in Centrinus hospes, which inhabits the same region. My series consists of seven specimens, THYSAXOCXEMIS Lee. In this genus the sexual divergencies in the structure of the beak are extremely pronounced and far more noticeable than in Tylop- terus, with which it is closely allied ; the present forms may be distinguished from Tylopterus, however, by the much coarser, less dense and non-sericeous vestiture. The fringe of hairs of the front tibiiB in the male is not a character of generic importance, and often disappears completely. The five species in my cabinet may be mutually distinguished by the following table: — Elytral intervals subequal in width and prominence. Body pale rufo-testaceous, the elytra with a broad, darker and generally less densely squamulose band, narrowed toward the sutnre, often indis- tinct ; sometimes also with a short angulate sutural band of paler scales near apical third fl'axilli Lee. Body piceous-black, the beak and legs rufous, the tibiie witli a narrow sub- median band blackish, the femora dark except toward base; vestiture strongly mottled with black and whitish, fulvous near the base of the elytra especially near the humeri, and on the pronotum except toward the sides and in the middle toward base ; on the elytra a wliitish band at basal fourth and a narrower angulate band at apical third are especially noticeable. Head squamose ; eyes separated by barely one-half of their own width ; beak in the male short but rather thin, feebly arcuate, as long as the prothorax, with the antennae inserted at apical third ; in the female very thin, smooth, cylindrical, evenly, distinctly arcuate, as long as the head and prothorax, with the antennte inserted at about the middle ; antennse long, thefunicle slender, with the basal joint more than one-half as long as the remainder, club robust, blackish, not as long as the pre- ceding six joints. Prothorax one-half wider than long, narrowed in apical third, the sides thence parallel and almost straight to the base. Elytra nearly one-half wider than the prothorax, three times as long, parallel, broadly rounded at apex, with the subapical umbones rather distinct. Length 3.0-3.3 mm.; width 1.3-l.G mm. Arizona (Winslow). Mr. H. F. Wickham grapllica n. sp. Body uniformly pale ochreous- testaceous throughout. Vestiture dense, pale yellowish, consisting of elongate subrecumbent scales, intermixed with narrower hairs on the pronotum, each elytral interval with a single series of very broad semi-erect distant scales. Head convex ; eyes separated by rather more than one-half of their own width ; beak in the male rather thick, cylindrical, feebly arcuate, finely, sublinearly punctate, barely as long as the head and prothorax ; 426 Coleopferological Notices, IV. anteniiEB inserted rather beyond apical third, the first funicular joint scarcely as long as the next three, club not as long as the preceding six joints combined. Prothorax nearly four-fifths wider than long, rounded and narrowed in apical half, the apex transversely truncate and about three-fifths as wide as the base. Elytra at base two-fifths wider than the prothorax, more than three times as long, broadly, feebly sinuate at base, the sides straight and parallel in basal three-fifths. Length 2.8 mm. : width 1.4 mm. Arizona squaniiger n. sp. Vestiture dense, consisting, on the pronotum, of long slender pointed subrecunibent squamules, on the elytra of similar squamules and with a single series of long robust lanceolate and suberect scales on each interval ; the latter scales very coarsely and deeply strigose. ochreous and piceous-black in color. Head densely hispido-squamose between tlie eyes, the latter separated by much less than one-half of their own width; beak in the male very short, thick, feebly bent, equal in length to the prothorax ; antennae inserted at apical third, the basal joint of the funicle but slightly longer than tlie next two, club very long, fusi- form, deeply annulated, longer than the preceding six joints combined. Prothorax scarcely more than one-half wider than long, the sides strongly convergent and nearly straight in apical half, the apex one- half as wide as the base ; punctures rather coarse, very dense ; vesti- ture uniform. Elytra nearly one-half wider than the prothorax, more than three times as long, the sides parallel and nearly straight in basal three-fifths. Length 3.5 mm. ; width 1.75 mm. Southern California. tiorridiila n. sp. Elytral intervals distinctly alternating in width, the wider rather more con- vex and more densely clothed ; body uniformly pale oclireous-testaceous throughout helTOla Lee. In gi'ajjhica, which is a very isolated species, intermediate in habitus between Thysanocnemis and Tylopterus, the pronotal ves- titure is fulvous except narrowly along the median line and at the sides toward base, where it becomes white, the white lateral area curved inward just behind the middle of the disk, giving the appear- ance of a transverse interrupted band. Otidocephalini. OTIDOC£PHALUS Chev. Since the last revision of this genus by Dr. Horn (Proc. Am. Phil. Soc, XIII, p. 448), several remarkable forms have been discovered in Florida and our extreme southwestern territories. In the memoir referred to, seven species were recorded as occurring within the United States, and one other was subsequently added by LeConte. Besides O. pet'/oratus, for which a separate genus Coleopterological Notices, IV. 427 is proposed below, fifteen species are now brought to notice ; prob- ably many more still remain unknown. Mexico appears to be the principal focal centre of Otidocephalus, and, although well repre- sented in Brazil, the genus would seem to be relatively less abun- dant there, being largely replaced by Erodiscus. The species are readily subdivided into well-marked groups based upon femoral, rostral and ungual structure, size of the eyes and nature of the vestiture as follows: — Beak without dorsal excavation; femora dentate 2 Beak with a large and very deep excavation near the middle ; femora un- armed 9 2 — Tarsal claws with a large, acutely angulate, internal lobe ; body with erect setae 3 Tarsal claws broadly swollen within toward base, but not at all angulate ; body entirely without erect setse 8 3 — Elytra with more or less dense recumbent vestiture in addition to the erect sette, the pubescence tufted in structure 4 Elytra with sparser recumbent or subrecumbent and paler hairs, simjile in structure and always confusedly distributed over the surface 5 Elytra with stiff erect white setcne, intermingled with longer, more slender, blackish hairs, all forming single series on the intervals 6 Elytra with simple erect seta?, either black or whitish in color, forming single series on the intervals 7 4 — Elytra each with four glabrous or subglabrous vitta?. Vittae narrow and sharply defined, with a few scattered tufts only near the apex 1 TittatU8 Vittse much wider, always with unevenly scattered pubescent tufts through- out the length, punctured and indefinitely limited ; body smaller and relatively stouter 2 nivosiis Elytra without four subglabrous vittse. Pubescence moderately dense, paler along the elytral suture and median line of the pronotum 3 tilkei Pubescence uniform in color throughout the upper surface, pale brownish- cinereous, broadly dense on the elytral intervals, but denuded in a narrow space on eacli side of the series of punctures, producing a multi-vittate appearance ; dorsal setae very short 4 iiisigllis 5 — Elytra without well-defined series of punctures, confusedly and unevenly punctate throughout 5 estriatlis Elytra with impressed even series of coarse deep punctures. Body very robust, the subrecumbent setfe coarse, abuiwlant, pure white and very conspicuous ; pronotum sparsely, unevenly and not coarsely punc- tate 6 egregius Body narrow, the subrecumbent shorter hairs sparse, somewhat dark in color and not very conspicuous ; pronotum coarsely and very densely punctate 7 sci'Ol)icollis Annals N. Y. Acad. Sci., VI, Sept. 1892.— 29 428 Coleopterological Notices, IV. 6 — Elytral series feebly impressed, coarsely, deeply and rather remotely punctured 8 floridaiilis •y — Eyes separated by much less than one-half of their own width. Elytral punctures fine, the series not impressed on the disk, the setse con- fined in great measure to the alternate intervals, except toward apex ; body rather stout 9 laeTicollis Elytral punctures coarser, the series just visibly impressed, the setse more abundant and conspicuous, widely spaced along all of the intervals ; body smaller and narrower 10 speculator Eyes widely separated. Elytra strongly infiated behind, the seta3 very sparse, rather short, whitish in color and only distinct toward apex 11 niyrinecodes Elytra but slightly wider behind the middle than at base ; setae numerous, long, blackish in color ; strial punctures coarser. Body stouter, the antennse rufous 12 riliicoriiis Body slender, the antennae black 13 lliyriliex S — Ferruginous, the elytra blackish in apical half or more ; body with short, white, slender, sparsely scattered and recumbent squamules ; femoral teeth very minute 14 dicIil'OIl!^ 9 — Polished, black, the legs, beak and antennae piceous ; pronotum and elytra glabrous, without erect setae, except a few borne from a series of punctures along the apical margin of the former on the flanks, and, on the latter, several toward apex, and one much longer and isolated on each side of the soutellum 15 cavirostl'is The division of the genus by the form of the prothorax is im- practicable, as, in several species, this part is more or less cylindrical in the male and obovate in the female, notably so in speculator. 1 O. vittatus Horn.— Proc. Am. Phil. Soc, XIII, 1873, p. 448. Elongate-oval, strongly convex, black, polished, densely clothed with white pubescence formed of recumbent tufted hairs ; each elytron with four narrow, feebly convex, abruptly defined, glabrous vittas and a much narrower uneven line very near the suture, the glabrous vittai narrow, but slightly more than one-half as wide as the pubescent stripes, and each with a series of small widely and unevenly spaced punctures bearing short piceous seta?. Beak short, thick, three-fifths to three-fourths as long as the prothorax, deeply, unevenly punctate at the sides, the antennEe inserted at apical two- titths in the female and but just visibly beyond in the male. Pro- thorax coarsely, unevenly punctate, with a polished fusiform tumid and almost entire median impunctate line. Elytra but slightly wider behind the middle than at base, almost twice as long as wide. Coleopterologicnl Notices, IV. 429 Legs rather stout, pubescent, the femora somewhat strongly toothed. Length 10-8.3 mm.; width 2.5-3.0 mm. Southern California. My series of five specimens indicates but slight variability, and the species, which is one of the largest of the genus, may be readily known by the narrow, abruptl}' glabrous, polished vittre of the elytra. 2 O. iiivosilS 11. sp. — Oval, feebly siibeuneate, black, polished, densely clothed with white recumbent pubescence formed of tufted hairs, intermingled with short stiff sparse piceous setae, the elytra each with five subglabrous vittse, the first adjoining the suture ; those of the disk fully two-thirds as wide as the pubescent stripes, all more or less confusedly punctate toward their lateral limits, and always unevenly and sparsely covered with tufted pubescence. Head sparsely pubescent, densely so between the eyes which are separated by but slightly less than their own width ; beak short, thick, straight, coarsely, rugosely punctate, rather densely pubescent in tufts through- out, three-fifths to three-fourths as long as the prothorax, the antennae inserted at apical third in the male, the second joint of the funicle almost as long as the first. Prothorax but slightly longer than wide, strongly inflated at about the middle, the base and apex subequal in the male, but the former relatively narrower in the female, coarsely, closely and unevenly punctate, with a sub- entire tumid impunctate line. Scutellum densely tomentose^ Elytra at base one-half to two-thirds wider than the base of the i^rothorax, slightly wider behind the middle than at base, three-fourths longer than wide. Legs moder- ate ; femoral teeth small, acute ; anterior tibiae obtusely strongly swollen or subdentate within at the middle. Length (J. 0-6. 5 mm. ; width 2.4-2.6 mm. Arizona (Peach Springs); Texas (El Paso). This species is closely allied to vittatus, but differs constantly in a number of structural features. The prothorax and elytra are )}oth less elongate, and the subglabrous stripes of the latter are wider, indistinctly limited and always more or less pubescent; the antenna' are rather more apical in insertion, the femoral teeth smaller, and the anterior tibise more strongly and angularly swollen within at the middle. The size is noticeably smaller than in vittatus. Three specimens. 3 O. Ulkei Horn.— Proc. Am. Phil. Soc, XIII, p. 449. This species is described as being moderately deuseh' clothed with pubescence, which is recumbent and composed of tufted hairs as in vittatus and insignis, the vestiture paler along the middle of the pronotum and elytra. The femora are minutely toothed. Length (exclusive of the head) 6.5 mm. Lower California. A single specimen in the cabinet of Mr. Henry Ulke of Washington. 430 Coleopterological Notices, IV. 4 O. ilisigllis n. sp. — Rather robust, subcuneate, very strongly convex, polished, black throughout, densely clothed with tufts of pale brownish-cine- reous pubescence, rather denser and whiter beneath, especially on the sternal parapleurse, semi-erect on the prouotum, where they are mixed with sparse, anteriorly directed and erect black setae, becoming white on the flanks and toward base, recumbent on the elytra and mingled with posteriorly-inclined, short sparse and whitish setae, mixed with blackish near the apex, the elytral intervals becoming abruptly glabrous near the series of punctures, producing a narrowly multi-vittate appearance, the median line of the prouotum and the elytral suture not at all paler.

Prothorax one-fourth longer than wide, the base a little wider than the apex, the sides strongly rounded and inflated at basal third, thence sinuate to the base ; disk coarsely, deeply, un- evenly punctate, the punctures denser above, sparser on the flanks, with a smooth impunctate median line in apical half. Scutellum rather large, tri- angular, extremely densely clothed with white pubescence forming a tumid mass. Elytra at base two-thirds wider than the base of the prothorax, but only one-fourth wider than the disk, nearly two and one-half times as long, not quite twice as long as wide, perceptibly wider behind the middle than at base ; disk with unimpressed series of fine, unevenly and moderately spaced punctures, the series but just visibly impressed near the lateral margin. Legs long ; femora strongly toothed; tibiae arcuate toward base. Length 8.5 mm. ; width 3.3 mm. Texas (El Paso). Mr. G. W. Dunn. The largest species which I have seen, and allied to ulkei in the development of the remarkable tufts of setae, densely covering the integuments ; each of these tufts is composed of three or four long slender hairs, which are united and attached at base by a short stout common foot-stalk. It differs from ulkei in the sculpture of the beak, in the denser vittae of the elytra, uniform in color and not paler at the suture, and in its larger size. 5 O. estriatllS n. sp. — Robust, extremely convex, shining, black, the beak antennae and entire elytra more or less rufo-piceous but dark ; pubescence simple, very sparse, recumbent, whitish, intermingled on the prouotum and elytra, especially toward apex, with extremely few remote blackish setae ; under surface rather sparsely clothed with long flexible whitish hairs, very dense on Coleopterological Notices, IV. 431 the sternal parapleurse. Head coarsely, deeply, very densely pnnctate, tiat and longitudinally rugose between the eyes, sparsely clothed with short whitish hairs ; eyes large, rather convex, separated by four-fifths of their own width ; beak thick, scarcely arcuate, not quite as long as the prothorax, gradually, distinctly dilated toward apex, with two approximate eroded and unevenly punctate grooves in basal half, sejiarated by a smooth impuuctate line, laterally very coarsely, deeply, densely punctate and rugose but not sul- cate, above toward apex strongly punctate and with two widely distant longi- tudinal impressions ; antennae inserted at apical third, the second funicular joint obconical, three-fourths as long as the first, club elongate-oval, densely pubescent, darker in color. Prothorax very slightly longer than wide, the apex broadly arcuate, a little wider than the base ; sides subparallel and nearly straight in apical two-thirds, then gradually rounded, convergent and sinuate to the base ; disk coarsely, deeply, unevenly and closely punctate, the punc- tui-es becoming finer near the apex, sparse on the flanks toward base and with a narrow subentire tumid impunctate line along the middle. Scutellum small, densely covered with yellowish-white tomentum. Elytra at base two- thirds wider than the base of the prothorax, two and one-half times as long, three-fourths longer than wide, only slightly wider behind the middle than at base ; humeri obtusely angalate, scarcely rounded, subprominent ; disk with- out series but with moderately fine, deeply impressed punctures unevenly distributed in longitudinal vittre, separated by subimpunctate narrower lines, which have exceedingly remote larger punctures bearing the stiff erect setse. Legs moderate in length, sparsely pubescent, the femora distinctly, acutely toothed beneath. Length 5.5 mm. ; width 2.1^ mm. New Mexico (Las Vegas). Mr. Meeske. The uneven sculpture and sparse recumbent vestiture distinguish this species from any other within our fauna ; it may perhaps be allied to the Mexican Jlavipennis Chev. 6 O. egregillS n. sp. — Oblong-ovoidal, strongly convex, rather robust, black and polished throughout, the upper surface clothed sparsely but con- spicuously with short robust recurved white set?e, unevenly scattered on all the interval of the elytra and mingled with longer finer erect and more widely dispersed piceous setse ; legs and under surface rather sparsely but distinctly clothed with short and more recumbent white hairs, dense and tufted on the sternal side-pieces and mesosternum between the coxae, also with sparser tufted hairs on the prosternum and toward the anterior margin of the meta- sternum. Head coarsely but not very densely or deeply punctate ; eyes large although not very prominent, separated by one-third of their own width ; beak thick, just noticeably wider at apex, feebly bent, three-fourths as long as the prothorax in the male, smooth and impunctate broadly along the middle, with a feeble impressed line between the antennae, coarsely, closely punctate and longitudinally sulcate laterally, hispid with erect setae ; antennae inserted at apical third, long, slender, the first funicular joint a little longer than the next two, club rather small, elongate, pointed, asymmetrically fusiform. Prothorax 432 Coleopterological Notices, IV. distinctly longer than wide, the base and apex subeqnal in the male, the former relatively narrower in the female ; sides feebly arcuate, convergent and straight toward base ; punctures rather small, feeble, remote and unevenly distributed. Scutellum densely pubescent. Elytra oblong, at base almost twice as wide as the prothorax, nearly two and one-half times longer, three-fifths longer than wide, not distinctly wider behind the middle than at base, the sides subparallel ; strife broadly, rather strongly impressed, coarsely, deeply and not very closely punctate; intervals convex, minutely, si:)arsely and unevenly punctate. Legs rather short and stout, the femora strongly toothed ; tibiae bent toward base. Lengtli 5.0 mm. ; width 1.9 mm. Arizona. The two specimens before me represent one of the most distinct species of the genus, recognizable at once b}' the numerous coarse recurved white set» of the upper surface, the subparallel elytra, relatively narrow prothorax, large eyes and large femoral teeth. It does not appear to be at all closely allied to any of the Mexican species. 7 O. SCl'Olt)icollis Boh — Sell. Gen. Cure, VII, ii, p. 205; Horn: Proc Am. Phil. See, XIII, p. 450.

Legs slender, the femora very long, the tooth small. Length 4.2 mm. ; width L6 mm. Pennsylvania to Texas. A well-marked species which cannot fail of recognition by reason of the sparse dual vestiture, coarse sculpture and long slender feebly toothed femora. It does not ap}tear to be abundant.

Legs rather short and thick, the femoral teeth large and prominent ; tibiae bent toward base. Length 4.0 mm. ; width 1.3 mm. Florida. A slender species, somewhat reseml:)ling vujrmex in form, but abundantly distinct in the mixture of lon_<>- white and l)!ackish setjfi of the upper surface, the longer elytra, and in the su))cvlin- drical and not obovate prothorax. 0 O. laeTicollis Horn.— Proc. Am. Phil. Soc, XIII, p. 451. Rather robust, feebly cuneate, strongly convex, polished, 1)lack throughout, the tarsi piceous ; upper surface very sparsely covered with moderately long erect setffi, white in color but becoming blackish on the disk of the pronotum anteriorly, and shorter and denser near the base, very remote in single series on the elytra, where they are confined for the most part to the alternate intervals ; under surface and legs covered with sparse semi-erect white sette, the scutellum and sternal parapleura3 densely pubescent.

Easily distinguishable b}^ the large promi- nent approximate eyes, and fine punctures of the unimpressed ely- tral series. The specimen described is a female. 10 O. speculator n. sp. — Subcuneate, strongly convex, black and highly polished throughout, the upper surface bristling with very sparse long erect setae, white in color but blackish on the disk of the pronotum toward apex, and forming an even single series on each of the elytral inter- vals, very sparse, shorter, finer and less erect on the under surface, tlie scutellum and sternal parapleurse densely albido-pubescent. Head smooth, scarcely at all punctate, the interocular surface setose, not depressed, slightly dull and remotely punctate; eyes large, prominent, separated by scarcely more than one-third of their own width ; beak in the male short, thick, straight, two-thirds as long as the prothorax, smooth and impunctate above, coarsely punctato-rugose at the sides, and above, in apical two-fifths, having two wide, depressed, dull and reticulate, parallel and rather approximate areas, the narrow interval being im^jressed along the middle ; in the female smoother above at apex ; antennae moderate, the first funicular joint robust, as long as the next two, second a little longer than the third, both elongate, the club elongate, pointed, asymmetrically fusiform.

Elytra one-half longer than wide, twice as long as the prothorax, and, behind the middle, distinctly more than twice as wide as the latter in both sexes ; humeri very broadly exposed, obtusely rounded; disk with very feebly impressed series of rather coarse distant punctures, the sutural series more strongly impressed as usual. Lexjs moderate, the femoral teeth rather small, acute. Length 3.5-3.7 mm. ; width 1.4-1.5 mm. Texas. This species, which is represented in my cabinet by three speci- mens, is closely allied to IsevicoUis, but differs in its smaller size, less rolnist form, more abundant and conspicuous white seta^ of the elytra distributed along all of the intervals, and in the coarser Coleopterological Notices, IV. 435 punctures of the elytral series. The sparse seta3 of the pronotum seem to be inclined to serial arrangement in basal half. 11 O. inyrinecodes Chev. — Ann. Ent. Soc. Fr., 1832, p. 445; cJwvrolati Horn : Proc. Am. Phil. Soc, XIII, p. 450.

Rhode Island, District of Columbia, North Carolina and Indiana; numerous specimens. This is a distinct species, easily known by its strongly, posteriorly inflated elytra, feebly developed dorsal setae, slender, straight, finely toothed femora and deep frontal fovea. I do not know the law or pi'ecedent under which the name given by Chevrolat was changed by Dr. Horn ; If myrmecodes Say is a synonym of myrmex Hbst., as seems to be undoubtedly the case, Chevrolat's name cannot be preoccupied. 12 O. rilficorilis n. sp. — Rather stout, convex, very feebly subcuneate, black throughout and highly polished ; antennae and tarsi brownish-rufous ; upper surface with numerous but very sparse, long, erect, blackish seta3, be- coming whiter near the elytral apex laterally and also on the under surface, where they are much shorter and subrecumbent ; scutellum and sternal para- pleurae densely albido-pubescent. Head and beak rather sparsely but evi- deJitly and unevenly punctate ; eyes separated by slightly less than their own width, the interocular surface broadly, feebly impressed between two feeble and distant carinae ; beak short, rather thick, nearly straight, not dilated 430) Coleopterolorjical Notices, IV. tow.ard apex, subglabrous, tliree-fourtbs as long as the prothorax, with two parallel uneven grooves on the disk, rather distant and obsolete at the middle, and, on each side at the declivity, a longitudinal groove, entire, but becoming feebler toward the apex, also coarsely punctate at the sides toward base, the punctures of the upper surface near the apex almost obsolete ; antenna mode- rate, the first funicular joint rather slender, obconical, second slightly longer than the third, club rather small, evenly elliptical, less than one-half longer than wide. Prothorax strongly convex, one-fourth longer than wide, the apex broadly arcuate, much wider than the base ; sides feebly divergent from the apex to the middle, then more strongly convei'gent and nearly straight to the base ; disk finely, remotely and unevenly punctate, the punctures impressed and distinct. Elytra at base two-thirds wider than the base of the protliorax, slightly but distinctly wider behind the middle, three-fourths longer than wide, the series scarcely at all impressed and composed of rather small, mode- rately close-set punctures. Legs rather stout, the femoral teeth large ; tibiffi only just visibly bent toward base. Length 4.7-5.0 mm. ; width 1.7-1.8 mm. Arizona. Allied closely to myrmex, but larger and stouter, with the elytral series finer and less impressed. I should have referred the two specimens in my cabinet to mexicanus Chev., as they agree toler- ably well with the description of Rosenskoeld, but the elytra, are evidently much shorter, their length being given as almost three times that of the prothorax in that species, while in ruficornis they are only twice as long. 13 O. inyriuex Hbst. — Kiifer, VII, p. .56; Horn: Proc. Am. Pliil. Soc, XIII, p. 450 ; mi/rmecodes Say : Cure. p. 15 ; Ed. Lee, I, p. 278 ; americanus Chev. : Ann. Ent. Soc. Fr., I, 1832, p. 105 ; Gyll. et Rosen. : Sch. Cure. Ill, p. 36(3; VII, p. 205. Narrowly and very feebly subcuneate, very strongly convex, polished, lilack throughout, the ui)per surface with numerous long- erect blackish hairs, on the elytra disposed in a single widely-spaced series on each interval, on the under surface and legs generally whiter, the sternal side-pieces densely clothed with white pubescence, recumbent, and tufted in structures as usual. Beak short ; antennsB slender, the funicular joints two to four subequal, each slightly elongate ; eyes moderate, separated by a little less than their own width. Prothorax strongl}^ convex before the middle, sparsely, rather strongly and unevenly punctate, one-fifth longer than wide, the apex broadly arcuate and but slightly wider than the base. Scutellum densely pubescent. Elytra very nearly twice as long as wide, rather distinctly wider behind; punctures coarse, the series Coleopterological Notices, IV. 431 feebly impressed. Legs rather slender; femoral teeth large ; til)ia3 bent toward base. Length 3.6-4.4 mm.; width L2-L6 mm. This is a common species, easily recognizable by its narrow form, the long blackish and somewiiat abundant seta3 of the upper surface, and the strong strial punctures. My specimens are from New Jersey, Pennsylvania and Indiana. 14 O. diclirous Lee— Proc. Am. Phil. Soc, XV, p. 191. Rather narrowly and feebly cuneate, less convex above than usual, polished and ferruginous throughout, the elytra piceous black in apical half to two-thirds ; erect setae completely wanting, the body throughout with extremely sparse recumbent squamules, very slen- der in form and white in color ; scutellum densely tomentose ; sternal side-pieces not densely pubescent, the met-episternum with a nar- row uneven line of squamules. Head finely, sparsely but distinctly punctate, with a deep elongate-oval interocular fovea ; eyes mode- rately large, strongly convex, coarsel\^ faceted, separated by fully one-half of their own width ; beak very short, thick, cylindrical, feebly sculptured even toward the sides; antenna? nearly normal, but with the club very indistinctly annulated, the scrobes passing beneath at a great distance from the eyes. Prothorax distinctly elongate, subcylindrical, feebly and gradually inflated to slightly l)ehind the middle, sparsely, distinctly but unevenly punctate. Elytra behind the middle twice as wide as the prothorax and much wider than at base, almost twice as long as wide; humeri broadly exposed ; striae feebly impressed, composed of coarse, deep, close-set punctures. Legs long, with short sparse recumbent squamules, not setose ; femoral teeth very minute, the posterior femora long and sublinear ; third tarsal joint very widely bilobed ; claws divaricate, thick, strongly arcuate, gradually swollen internally toward base Ijut not in the least angulate. Length 4.1-4.7 mm.; width 1.4- 1.75 mm. Georgia and Florida. The large series in my cabinet seems to indicate Init little variability, except in the extent of the l)lackish area of the elytra. This remarkal)le s})ecies is aberrant in its vesti- ture and in the structure of the tarsal claws. 15 O. cavirostris n. sp. — Narrowly subcuneate, liiglily polished, strongly convex, black, the legs, beak and antenna piceo-rufous ; body almost completely glabrous, a few erect setiB near the anterior margin of the prothorax, a long seta near the scutellum and a few toward the elytral apex being all that are visible 438 Coleopterological Notices, IV. in the type ; scutelhim, mesosternal side-pieces and met-episterna posteriorly, densely clothed with recumbent white pubescence. Head sparsely but dis- tinctly punctate toward base and between the eyes, elsewhere entirely impunc- tate ; eyes rather large, moderately prominent, separated by a little less than their own width ; beak very short and robust, barely more than one-half as long as the prothorax, parallel, rather wider than thick, with a- large and ex- tremely deep excavation just behind the middle, occupying the entire width, rounded and bounded by an acute densely ciliate edge on the sides and behind, the anterior edge obtuse and transverse ; bottom of the cavity ascending an- teriorly and feebly bicarinate ; rostral surface between the cavity and apex and also at the sides throughout, strongly though not very densely punctate ; antennae short, the basal joint of the funicle robust, second slightly elongate, third not quite as long as wide, outer joints thicker, club nearly as long as the preceding six joints, strongly annulated. Prothorax distinctly longer than wide, widest at two-fifths from the base, the sides thence almost straight and very feebly convergent to the broadly arcuate apex, and strongly convergent and constricted to the base, the latter barely three-fifths as wide as the apex ; disk finely but strongly, almost evenly and somewhat closely punctate. Scu- telluni distinct. Elytra scarcely more than one-half longer than the prothorax, and, at base nearly twice as wide as the base of the latter but not wider than the disk, gradually rather strongly inflated posteriorly, and, behind the middle, two-fifths wider than the disk of the prothorax, three-fourths longer than wide, very strongly, evenly convex longitudinally ; humeri rather prominent, nar- rowly rounded, the exposed basal portion oblique ; striae feebly impressed ex- cept toward apex, the punctures small, moderately close-set and distinct. Legs rather long, very slender, the femora linear, scarcely at all sinuate toward apex and completely unarmed ; tarsal claws normal. Length 1.9 mm. ; width 0.6 mm. Florida. The single specimen of this extremely interesting species was taken in the southern part of the State by Mr. F. Kinzel, and very kindly presented to me by Mr. Wilhelm Jiilich. It is related to the Cuban poe/yz Chev. in the extraordinary rostral excavation and un- armed femora, but differs in coloration and, probably also, in its smaller size and more sparsely punctate head. It is by far the most minute of our species, and, together with poeyi, might well be separated as a distinct genus. OOPTERINIJS u. gen. This genus is founded upon a remarkable species described by Dr. Horn under the name Otidocephalus perforatum. It differs from Otidocephalus in having the elytra ovate, rounded on the sides, widest a little before the middle, gradually attenuate and Coleopferological Notices, IV. 439 acutely rounded behind, and with the humeri entirely obsolete, in the complete absence of scutellum, and in its small eyes. The elytra are probably subconnate. In its short deeply sinuate pro- sternum, short beak, and toothed claws, Oopterinus resembles Otidocephalus. O. perforatum Horn. — Proc. Am. Phil. Soc, XIII, p. 451. Oval, piceous, the elytra and legs still paler, the upper surface with a few rather short, semi-ei'ect, widely scattered whitish setsB. Head sparsely but strongly punctate, the interocular surface impunc- tate but with a small rounded median fovge ; eyes remarkably small, coarsely granulated, separated by fully their own width ; beak rather thick, feebly arcuate, almost as long as the prothorax, strongly punctured at the sides and with a short longitudinally impressed line between the antennae, the latter slender, the second funicular joint obconical, one-half longer than the third ; club oval, rather sparsely pubescent. Prothorax longer than wide, strongly narrowed and feebly constricted toward base, very coarsely, deeply, slightly unevenly but rather closely punctate. Elytra ovate, two-thirds longer than wide, widest before the middle, the sides evenly rounded ; humeri obsolete ; punctures very fine, dispo.sed in even series which are entirely unimpressed except near the base. Legs very slender, the femora broadly emarginate near the apex but not toothed. Length 3.3 mm.; width L3 mm. The single specimen in the LeConte cabinet has no indication of locality, but the original type, in the cabinet of Mr. Ulke, is from Maryland. Cryptorhynchini. CONOTRACHELL^S Schonh. The following rather isolated species may be referred at present to the groups outlined by Dr. LeConte. C. COnipositUS n. sp. — Oblong-oval, moderately convex, not at all shin- ing, black, the legs and antennse rufo-piceous ; elytra clothed densely witli short recumbent hairs, piceons in color, fulvous along the ridges and yellowisli in three elongate spots at the base of each, the two outer coalescent, the pronotum more sparsely pubescent, with a few whitish hairs scattered in an oblique line at each side ; upper surface throughout bristling with short stitf erect setse. Head and beak densely hispid with short bristles and more recumbent hairs ; front foveate ; beak separated from the liead by a deep 440 ColeojJterological Notices, IV. transverse impression, very short and thick, distinctly and evenly arcuate, four-fifths as long as the prothorax, very deeply coarsely and densely punctato- subsulcate and dull ; antennae inserted at apical third, the second funicular joint scarcely as long as the first but rather longer than the next two. Fro- thorax not quite as long as wide, the sides in basal three-fourths parallel, straight but convergent near the base, rather prominent at apical fourth, thence convergent and constricted to the apex ; disk evenly convex but ex- ceedingly coarsely, roughly punctato-foveate, the fovese closely crowded and irregular, with a fine strong carina in apical half, rendered more prominent by a depression in the surface at each side of it. Elytra at base three-fifths wider than the prothorax, two and three-fourths times as long, one-third longer than wide, the sides parallel toward base, sinuate near the apex ; humeri broadly exposed, prominent and obtusely carinate ; disk with unim- pressed series of large deep rather close-set punctures ; intervals flat, the third obtusely tumid at the base, before the middle and through apical third, the fifth more especially from basal third to the subapical impression, the seventh at the huiueri and to a greater or less degree along its entire extent. Abdomen with not very dense large and small punctures. Femora with two acute spini- form teeth ; tarsal claws divergent, strongly toothed. Length 5.4 nnu. ; width 2.5 mm. Arizona. May be associated with affinis for the present, but widely dis- tinct from any other described species known to me. C. carillifer n. sp. — Oblong-oval, feebly convex above, not shining, piceous-black, the elytra, legs and antennae more or less rufescent ; elytra clothed densely with short recumbent hairs, fulvous, mottled unevenly with whitish, the latter more evident in a transversely lunate area at apical third, also with a few widely scattered extremely short recurved and semi-erect setse ; pronotum glabrous although sparsely setose. Head finely, closely punctate, fulvido-pubescent, the beak long, slender, arcuate, two-fifths as long as the body in the male, finely but strongly punctato-sulcate, separated from tlie eyes at the sides by a deep vertical groove ; antennae inserted just behind the extreme apex, very slender, the second funicular joint longer than the first. Prothorax one-fifth wider than long, the sides parallel, broadly, feebly, evenly arcuate nearly to the apex, then rounded convergent and constricted ; apex broadly arcuate and nearly three-fourths as wide as the base ; disk with ex- tremely large deep and closely crowded foveae, each bearing a short anteriorly directed seta ; surface evenly convex but finely, very strongly carinate along the middle. Elytra one-half wider than the prothorax, two and one-half times as long, one-third longer than wide, ovoidal, the sides becoming parallel toward base ; humeri widely exposed, rounded ; disk with unimpressed series of coarse deep close-set punctures ; intervals flat, the alternate broadly, feebly carinate, the carinse entire. Abdomen coarsely, closely punctate. Legs moderate, the femora uni-dentate. Length 4.3 mm. ; width 2.2 mm. Coleopterological Notices, IV. 441 Texas (Austin). This is an interesting species, allied to naso, but having- the antennae of the male still more apical in insertion, and the pronotal sculpture nearly as m fiHSuriguis. A single specimen. C integer n. sp. — Oblong-oval, moderately convex above, dull, black, the elytra and legs with a feeble piceous tinge; ijubescence of the elytra not very dense, consisting of sliort recumbent liairs, ochreous or fulvous in color, nearly evenly distributed and scarcely at all mottled, mixed with short sparse set;ie, not paler or denser behind the middle, the pronotum sparsely setose. Head densely and rather finely punctate, the yellowish pubescence not extending beyond the front ; beak long, slender, arcuate, about one-half as long as the elytra in the male, strongly sulcate, the antennas inserted beyond apical third. Prothorax very nearly as long as wide, the sides broadly rounded anteriorly, becoming parallel and nearly straight in basal three-fifths, finely, moderately constricted just behind the apex, the latter not more than one-half as wide as the base ; disk coarsely, extremely densely, unevenly and subconfluently punctate, evenly convex and with a fine entire median carina. Elytra one-half wider than the prothorax and not quite three times as long, two-fifths longer than wide, the sides becoming subparallel in basal half; humeri right, widely exposed but rounded ; disk with series of moderately large deep close-set punctures, the alternate intervals with fine strongly-marked entire carinae. Abdomen coarsely, very deeply and densely punctate. Legs long ; femora moderately robust, subfusiform, obtusely and very feebly uni-dentate, the toothed appearance caused principally by the abrupt and deep subapical emargination ; tarsal claws divergent, strongly toothed. Length 6.0 mm. ; width 2.9 mm. Arizona (Tucson). The single male represents a species allied to vaso, but with the pubescence of the elytra much sparser and not at all condensed or whiter behind the middle, and the pronotal sculpture more than twice as coarse, being fully as coarse as in geminatus. Both this species and carinifer have the peculiar oblong-oval form and general rostral structure of naso, and should evidently be associated with it. C. tlliplex n. sp. — Robust, suboval, strongly convex, blackish-piceous, the elytra rufous ; vestiture of the anterior parts very sparse, in the form of long stifi" anteriorly directed setis, on the elytra of moderately dense, somewhat uneven prostrate hairs, coarser denser and paler yellowish toward the humeri and transversely behind the middle, also with long stiff' erect setse. Head densely punctate and with sparse subrecumbent yellow hairs, the front with a deep median fovea ; eyes moderate, remotely separated ; beak moderately thick, feebly, evenly arcuate, fully as long as the head and prothorax, very deeply, longitudinally punctato-sulcate, strongly carinate along the middle ; antennae inserted at apical third, the second funicular joint very long, about 442 ' Coleopterological Notices, IV. as long as the first and twice as long as the third. Prothorax very nearly as long as wide, the sides subparallel and just visibly arcuate in basal two-thirds, then convergent and rather strongly constricted, the apex somewhat strongly arcuate, three-fouFths as wide as the base ; disk very coarsely, deeply punc- tate, the punctures even but closely crowded and polygonal, without trace of any kind of median line. Elytra three-fifths wider than tlie prothorax, two and two-fifths times longer, only slightly longer than wide, the sides becoming straight and nearly parallel in basal half; liumeri riglit, narrowly rounded, broadly exposed at base ; disk with series of rather coarse punctures ; inter- vals three, five, seven, eight and nine more or less strongly and uninter- ruptedly carinate. Abdomen coarsely deeply and densely punctate. Legs not very robust, the femora with a single fine tooth ; claws feebly divergent acutely toothed internally near the base. Length 4.3 mm. ; width 2.3 mm. California. Mr. Harford. Somewhat resembles fissunguis in form, but differs in the alter- nately broadly carinate elytral intervals and the long bristling erect seta3, as well as in the structure of the claws. The precise locality is unknown, but is in all probability southern, as Conotrachelus does not appear to enter the true Pacific coast fauna. C. rotundUS n. sp. — Robust, oval, convex, black, the legs rufescent ; vestiture of the pronotum sparse, of the elytra rather dense and consisting of very short robust subrecumbent squamules, smaller even and ochreous on the alternate intervals, whiter broader and submaculate on the others, the upper surface throughout with stout erect clavate bristles, rather sparsely but evenly distributed and moderate in length. Head finely, very densely punctate ; eyes remote ; front and basal parts of the beak densely squamulose ; beak rather thick, evenly arcuate, fully as long as the head and prothorax, deeply, longi- tudinally sulcate ; antennae inserted near apical third, rather stout, the second funicular joint scarcely as long as the first. Prothorax small, two-fifths wider than long, the sides feebly convergent from the base and rather strongly arcuate, more strongly convergent near the apex but not distinctly con- stricted ; apex broadly arcuate and about three-fourtlis as wide as the base ; disk with extremely coarse uneven and densely crowded fovese, tlie surface rough but evenly convex and without median line. Elytra abruptly four- fifths wider than tlie prothorax, not quite three times as long, not longer than wide, the sides parallel and nearly straight to the middle, then convergent and rounded feebly sinuate before the apex ; disk with broadly, deeply im- pressed series of moderately large deep punctures, the intervals nearly equal throughout and broadly, evenly convex, not in the least carinate at any point. Abdomen rather coarsely, densely punctate. Legs not very stout, the femora eacli with a single rather small but distinct tooth ; tarsal claws rather diver- gent, bent downward near the base and with a long straight internal tooth near the base, widely diverging from the claw and almost eqitalling it in length. Length 3.0 mm. ; width 1.9 mm. CoIeo2:>te7'oIogical Notices, IV. 443 Texas (near Austin). A distinct species, easily distinguishable by its rather small size, obese form and peculiar thick clavate bristles. Tog-ether with diqjlex, it should be placed at the end of LeConte's group "I b," but there are no described species with Avhich either of them can be compared. The genera allied to Ryssematus, which have thus far occurred within the United States, may be readily distinguished as follows: — Intermediate coxre narrowly separated ; second ventral segment not as long as the next two combined. Tarsal claws unequally cleft, approximate but not connate at base. Ryssematus Tarsal claws simple, stout, subparallel, subconnate at base, the suture dis- tinct Clialcoderniiis Intermediate coxse widely seijarated, the mesosternum between them depressed and flat ; second ventral segment longer than the next two ; tarsal claws small, slender, approximate at base but free Clialepoiiotus RYSSEMATUS Chey. B. pruinosus Sch. is somewhat aberrant in its more elongate-oval form and in the longer flatter abdominal segments, also in its very slender beak, joined at the lower part of the head at an obtuse angle. R. ovalis n. sp. — Evenly oval, strongly convex, shining, glabrous, dark rufo-testaceous throughout. Head strongly convex, finely, densely punctate, with a small interocular fovea ; eyes moderate, unusually distant, separated by rather less than their own width above ; beak rather slender, evenly, moderately arcuate, shining, finely, sparsely lineato-punctate, a little longer than the head and prothorax ; antenna inserted just behind the middle, the scrobes horizontal, nearly attaining the lower portion of the eye ; funicle long, slender, all the joints longer than wide, the first almost as long as the next three, second but slightly longer than the third, the club moderate, scarcely longer than the three preceding joints, oval, abrupt. Prothorax not quite twice as wide as long, the apex strongly constricted and tubulate, less than one-half as wide as the base ; sides evenly convergent and arcuate from the base, the latter transverse, broadly, feebly bisinuate and with the usual narrow decliv- ous margin ; disk finely, deeply strigilato-punctate, the strigae externally oblique anteriorly, the median line very fine and not distinctly cariniform. Elytra slightly wider than the prothorax and nearly three times as long, oval, the sides becoming parallel near the base, the humeri obliquely, feebly rounded externally to the prothorax and not exposed at base; disk with Annals N. Y. Acad. Sn., VI, Sept. 1892.— 30 444 Coleopterological Notices, IV. strongly impressed stri^e of moderately coarse deep elongate punctures, the intervals equally convex, becoming somewhat acute toward apex, finely and unevenly punctate along the sides of the grooves. Abdomen finely, rather sparsely punctate. Legs short, the femora very robust, the denticle strong ; tibiae stout, bent toward base, enlarged toward, and externally prominent at, the apex. Length 3.8 mm. ; width 2.0 mm. Texas. A rather small, evenly convex and isolated species, having the eyes much more widely separated than in any other form which I have seen. The structural characters are, however, all of this genus. The ocular lobes are moderately well developed as usual in this group. Chalcodermus includes but three species within our faunal limits, — seneus, insequicoUis, and collaris. The species identified by LeConte as spinifer Boh., belongs to a widely different tribe of Curculionidffi. CHAI.EPO]¥OTUS n. gen. This genus is allied to Chalcodermus, but differs in the following characters : — Antennal scrobes feebly descending to the lower angle of the eyes, the basal joint of the funicle not as long as the second. Second abdominal segment much longer than the next two combined, the suture broadly, evenly angu- late throughout its width. Middle coxse widely separated. Tarsal claws small, slender, approximate at base but not at all connate. It also differs in many other features, the body, for example, being more finely sculptured, aud the elytral intervals elevated as in many species of Ryssematus. The mandibles are very thick, strongly, evenly arcuate in external outline, the apex prolonged and acute. C elllSllS n. sp. — Oval, convex, shining, black, glabrous; each puncture bearing a vnry minute seta. Head finely, not very densely punctate ; eyes rather distant, separated by nearly their own width on the front ; beak rather slender, cylindrical, evenly, feebly arcuate, as long as the head and prothorax, finely, sparsely punctate, shining, the antenn?e inserted a little beyond the middle, the second funicular joint elongate, fully as long as the next two, outer joints thicker, the seventh scarcely as long as wide, club scarcely longer than the three preceding joints, oval, pointed, not very abrupt. Prothorax scarcely more than one-fourth wider than long, subconical, the sides evenly convergent and broadly arcuate from the base to the distinct but not strong subapical constriction, the apex arcuate, a little more than one-half as wide as the base ; disk finely, deeply and evenly punctate, the punctures separated Coleopterological Notice.^, IV. 445 by nearly their own widths, with a narrow impunctate spot at tlie middle. Scutellum small, tumid. Elytra one-third wider than the prothorax, two and one-half times as long, ogival, the sides becoming scarcely parallel at base, the humeri oblique to the base of the prothorax ; disk with fine impressed stripe, having moderately small deep elongate and remote punctures, wider than the strise, the intervals equal, strongly, angularly convex, with a feeble series of small punctures at each side of the summit. Abdomen finely, sparsely punctate. Legs moderate ; femora not very stout, the denticle strong, inclined ; tibi?e rather slender. Length 4.0 mm. ; width 2.0 mm. Indiana. Easily distinguishable by the fine even separated punctures of the prothorax, the latter being unusually elongate. A single specimen. ACAMPTIJS Lee. This is a conspicuously distinct and aberrant genus with the met- epimera invisible, the episterna distinct, the anterior coxa? large, prominent, contiguous but excavated internally to receive the very short thick beak, the eyes concealed in repose, antenual club solid, and third and fourth abdominal segments short. The tibi;\.' termi- nate in an unusually large internal spur and the tarsi are slender and cylindrical, with the third joint undilated ; the claws are slen- der, free and divergent. The bod}^ is narrow and elongate, brist- ling with thick erect clavate seta?. The two species may be thus distinguished: — Elytra shorter, scarcely more than one-half longer than wide and not twice as long as the prothorax, the latter broadly and feebly constricted behind the apex ; dorsal bristles short and sparse throughout, the elytral ridges moderate rigid IIS Lee. Elytra much longer, fully three-fourths longer than wide and more than twice as long as the prothorax, the latter broadly and deeply constricted behind the apex ; dorsal bristles twice as long and very close-set, extremely robust and squamiform ; elytral ridges strong. Body elongate, parallel, subcylindrical. Head and beak densely squamose, the latter bristling with erect scales especially toward base, not more than two-thirds as long as the prothorax, the antennse inserted near the middle, the funicle gla- brous, the basal joint aboiit as long as the next two, outer joints gradu- ally thicker, coarctate, club rather small. Prothorax fully as long as wide, the apex broadly arcuate and slightly narrower than the base, coarsely, indistinctly punctate. Scutellum small, distinct. Elytra one-third wider than the prothorax, the sides straight and nearly parallel in basal three- fourths, each with four ridges bearing long erect close-set scales, the in- tervals alutaceous, biseriately punctate. Length 4.3 mm. ; width 1.6.5 mm. New York ecliiiiUS n. sp. 446 Coleopterological Notices, IV. The vestiture is pale yellowish in color throughout, the integu- ments in echinus being dark red-brown. In both of the species the prothorax is very obliquely truncate at the sides, so that the head and beak are invisible from above ; the ocular lobes are small. The antennal funicle is 7-jointed and not 6-jointed as indicated in the original description. MICROMASTCJS Lee. The principal sternal characters of this genus appear to have been in great part misconceived by the author. The beak is moderately thick and perfectly free, the prosternum broadly, feebly impressed, the impression punctate, setose and much wider than the beak, the anterior coxae large, conoidal, prominent and subcontiguous. The intermediate coxa3 are somewhat Avidely separated, the mesosternum between them transversely tumid, densely punctate and setose. The metasternum is only moderately short and is longer than in Acalles ; epimera and episterna both invisible, the third and fourth abdomi- nal segments short. Micromastus is an isolated genus intermediate between Conotrachelus and Acalles. ACALLES Schoiih. The following is a large species belonging in the neighborhood of nohilis : — A. profusiIS n. sp. — Oval, convex, black rather sparsely clothed with large recumbeut scales, without erect setse, the scales dark brown in color but in great part white and denser on the head and basal parts of the beak, in several small isolated spots on the prothorax, on the elytra especially near the sides in basal fourth and in a transverse band near apical fourth, on the femora toward apex and throughout the tibife. //eacZand beak rather coarsely, densely punctate, the latter finely carinate along the middle, rather longer than the prothorax ; antennae inserted at the middle. Prothorax very nearly as long as wide, the sides broadly arcuate, somewhat more convergent toward apex, the subapical constriction fine ; apex broadly arcuate and a little more than three-fourths as wide as the base ; disk coarsely, very densely punctate, the median impunctate carina strong but not entire. Elytra oval, more than twice as long as the prothorax, and, in the middle, nearly one- half wider ; foveas very large, deep and close-set, each with a rather small subquadrate scale. Abdovien coarsely, rather closely punctate. Length 7.5 mm. ; width 3.7 mm. Texas. Differs from porosus and basalis in its larger size and strongly Goleopterological Notices, IV. 44t carinate pronotum, and from nobilis in its less inflated elytra and the dense white scales covering the basal third of the beak. CAWISTES n. gen. This genus is founded upon a remarkable species somewhat re- sembling an unusually robust Calandrinus. It is however allied to Acalles, as may be seen from the following diagnosis : — Body oblong-oval, strongly convex. Beak moderate in length received in a very deep and abruptly limited sternal sulcus, extending almost to the metasternum. Eyes not very large, almost completely concealed in repose, the ocular lobes moderate. Antenn?e inserted just behind the middle of the beak, the funicle 7-jointed, slender, the basal joint not quite as long as the second, the latter nearly as long as the next three combined ; outer joints but slightly thicker ; club abrupt, rather large, elongated, cylindric-oval, fully as long as the preceding five joints, very densely pubescent, solid but with a distinct apical segment. Metasternum very short, the episterna distinct, parallel, the epimera not visible. Abdomen with the first suture distinct, broadly, strongly arcuate, the second segment much longer than the next two together. Legs thick and robust ; femora unarmed ; tibi?e aberrant, the inter- mediate and posterior gradually and rapidly increasing in width to the middle, then abruptly narrowed, the apical half parallel and not wider than tlxe base, the inner side straight throughout ; tarsi short, slender, the third joint dilated and bilobed ; claws small, simple, very slender, free and divergent. Seutel- lum completely obsolete. Canistes differs greatly from Acalles in abdominal structure, but resembles A. nuchalis not only in this feature, but in the broadly visible met-episterna. The new genus which must be formed for A. nuchalis will however differ from Canistes in its distinctly annu- lated antennal club and normal tibise. In general facies Canistes departs widely from any other type of North American crypto- rhynchs. C. SCllUSteri n. sp. — Subparallel, black, the antennae rufous with the club still paler and subsericeous ; body sparsely and very unevenly squamose, the head extremely densely clothed with small fulvous recumbent scales, the pronotum with some similar but more elongate scales toward the sides and also bristling with short erect and sparse setae, especially toward apex, the elytra smooth, alutaceous almost glabrous, with a few widely scattered scales of various shapes, some recumbent, others erect, especially visible toward base, in a transverse line at apical third, and thence narrowly along the suture to the apex, the abdomen with a few elongate and widely dispersed scales ; legs densely and conspicuously clothed throughout with small recumbent brown scales, erect and bristling externally along the tibiae. Head densely punc- 448 Coleopterological Notices, IV. tate ; beak feebly arcuate, not quite as long as the prothorax, smooth, shining and finely, sparsely punctate except in less than basal half, where it is punc- tate and squamose. Prothorax slightly wider than long, wider at the middle than at base, the sides in basal half nearly straight, strongly convergent and deeply sinuate anteriorly, the constriction very large, deep, extending entirely across the dorsal surface ; disk coarsely perforato-cribrate, the punctures sepa- rated by much less than their own diameters, the interspaces flat and polished, without modified median line. Elytra scarcely wider than the prothorax, two- thirds longer, narrowed and broadly constricted behind, the apex narrowly obtuse ; disk with very fine sparse punctures, not striate, the punctures how- ever becoming coarse and seriate very near the base. Abdomen finely, sparsely punctate, smooth and polished toward base. Length 3.3 mm. ; width 1.(3 mm. JNIissouri (St. Louis). The single specimen was discovered by Mr. Moritz Schuster of St. Louis, to whom it gives me pleasure to dedicate a most interest- ing addition to our Cryptorhynchiui. TYLODERMA Say. This genus is widely differentiated from Cryptorhvnchus l)y the short thick beak, consequently received in a much more shallow emargination of the tumid mesosternum, by the small eyes, almost completely concealed in repose by the ocular lobes, and by the six- jointed antennal funicle ; in addition, it should be stated that the femora are unarmed and are only moderately stout. The third tarsal joint is dilated and bilobed, and the tarsal claws are small slender free and simple. The species usually vary greatly in the size of the body and in intensity and coarseness of sculpture, espe- cially that of the elytra. In a perfectly natural succession of the North American forms we can readily recognize four typical groups, represented respec- tively hy foveolata,^ fragaiHse, variegata and eerea, the species in each group being rather closely allied among themselves. The 1 It is desirable to make the rules of nomenclature as uniform as possible, and independent of linguistic exceptions. This can be accomplished in one direction by adopting a constant gender for each particular ending of the generic symbol, taking as a guide the general Latin rule in each case. In this instance, it is the general rule that words ending in " a" are feminine, conse- quently all generic symbols ending in "a," of whatever derivation, should require a feminine termination in the specific word. It would be a decided advance if a table of genders could be drawn up and agreed to, for every pos- sible ending of the generic symbol. Coleopterological Notices, IV. 449 second of those mentioned is monotypic and is perhaps the most aberrant in general form and habitus. The species occur through- out the United States, and are also well represented in Brazil ; those which I have been able to study may be characterized as follows: — Body more or less dull, very coarsely, deeply sculptured, the protliorax with large uneven fove?e. Elytra with a squamulose spot at each side of the scutellura. Elytral series hecoming subobsolete and feebly punctate near the apex. Pronotal fovese much larger than the scutellura ; vestiture composed of brownish-white squamules 1 foveolata Pronotal fovese sensibly smaller and more distant, not much larger than the scutellura at any point ; squaraules broader in forra and white. 2 mor1)iIlosa Elytral series distinct throughout, the punctures of the two series nearest the suture on each deep and large to the apex ; body much narrower and more cylindrical, the jirothorax from above not constricted at the sides toward apex 3 angtistllla Elytra without trace of a squamulose spot near the scutellura ; elytral series broadly, deeply impressed to the apex ; prothorax not sensibly sinuate at the sides anteriorly ; humeri much less broadly exposed, not at all trun- cate at base but broadly rounded to the base of the prothorax. 4 contiisa Body smoother and more shining, glabrous or very sparsely and unevenly pubescent, less distinctly polished in fragarice, the pronotum punctate rather than foveate. Elytra oval, widest near basal third ; pronotum very coarsely deeply and densely punctate ; integuments in great part rufo-2)iceous...5 fragariae Elytra becoming parallel and straight at the sides toward base. Integuments more or less pale ; pronotal punctures coarse uneven and impressed. Prothorax rather longer than wide, densely and confusedly punctured toward apex ; elytra black, sparsely mottled with rufous. 6 variegata Prothorax not as long as wide, much more broadly inflated toward base, remotely and unevenly punctate throughout ; elytra rufous, occa- sionally very distantly and just perceptibly mottled with blackish : beak shorter 7 rilfesceilS Integuments black or piceous-black, often aeneous, rather shining ; pro- notum more or less minutely punctate. Elytral humeri very narrowly exposed at base 8 1)ai'iilia Elytral humeri broadly exposed. Upper surface with very sparse whitish recumbent hairs. 9 sulbpubescens Upper surface glabrous. Punctures of the pronotum strong tliough sparse throughout ; body rather robust 10 nigra 450 Goleopterological Notices, IV. Punctures of the prouotal disk very fine or subobsolete ; body nar- rower. Punctures of the pronotal tlanks strong and unevenly distributed over the entire surface 11 aerea Punctures of the flanks entirely obsolete, except in the sul^apieal constriction 12 punctata T. longa Lee. (Proc. Am. Phil. Soc, XV, p. 248) belongs to Cryptorhyuehus as at present organized, and has the eyes large and approximate, as usual in that genus. I have before me one or two species from Brazil, which are similarly elongate-cylindrical in form and otherwise closely allied to longa. In these forms the antennal funicle is short and T-jointed, the outer joints very short, gradually slightly thicker and coarctate ; they should perhai>s form a distinct genus. 1 T. fOTeolata Say.— Cure, p. 19; Ed. Lee, I, p. 284; Germ.: Soh. Cure, IV, p. 140 (Cryptorhyuehus) ; Horn: Proc. Am. Phil. Soc, XIII, p. 468 (Analcis). Oblong-oval, strongly convex, black and dull throughout, gla- brous but with small patches of small slender dense recumbent and whitish scales, of which a small spot at the middle of the vertex and another larger and more elongate between the eyes, a short line at the apex of the pronotum and an obliquely arcuate series from before the middle to near the sides of the base, numerous irregular .spots on the elytra and a broad uneven band at apical fourth, are especially noticeable. Head and beak not very coarsely but rather closely and distinctly punctate, with a feeble frontal puncture. Pro- thorax scarcely as long as wide, strongly rounded at the sides, the latter convergent and broadly sinuate toward the broadly arcuate apex ; disk with extremely coarse, deep, uneven but rather close-set fovea?. Elytra between one-third and one-fourth wider than the disk of the prothorax, the sides subparallel and nearly straight in basal two-thirds, the humeri right but narrowly and obliquely sub- truncate; disk with unimpressed series of extremely large deep uneven fovea?, which become almost obliterated toward apex. Length 3.7-5.8 mm. ; width L5-2.7 mm. The large series before me is from New Jerse}^, Pennsylvania and Iowa ; it is also said to occur in Georgia. In well preserved speci- mens each of the large fovetB of the pronotum bears a short stiff subclavate seta. The only remarkable variation is in the size of the body.

Closely allied to foveolcUa, but a little less robust, the elytra more elongate and with the small spots and posterior interrupted band composed of squamules which arc whiter and slightly broader, the scales of the small spots on the head and flanks of the prothorax still broader. The prothorax is shorter, with the apex relatively wider, broadly arcuate, the sides in basal three-fifths nearly parallel and much less arcuate, thence feebly convergent and just visiljly sinuate to the apex ; fovea? smaller, rather sparser and very unevenly distributed. Elytra one-fourth wider than the prothorax and rather more than twice as long, the sides parallel and nearly straight in basal two-thirds, the apex narrowly parabolic; humeri right, slightly blunt; foveae very large, uneven in outline, forming vague series and almost contiguous toward base, the series fine, slightly im- pressed and very feebly punctate toward apex, the two lateral more distinctly punctate and feebly carinate externally in apical half. Length 5.0 mm. ; width 2.0 mm. California (San Francisco). The unique type in the LeConte cabinet is the only specimen which I have seen. This species may possibly prove to be a geographical variatioif of foveolata, but it is impossible to pronounce any definite opinion until more specimens are discovered. 3 T. angustllla n. sp. — Subelongate, strongly convex, black, the legs dark piceo-rufous ; integuments dull, the elytra more shining, subglabrous but with a small condensed spot of recumbent squamules on tlie front, a few scattered squamules near the centre of the occiput, some very sparse indefinite spots on the prothorax and anterior parts of the elytra especially near the scutellum, an oblique spot near apical fourth and aiaother between this and the apex of each elytron, the squamules whitish in color. Head and beak very unevenly but distinctly punctate, the former more sparsely and with an indistinct frontal fovea ; beak very short, barely one-half longer than wide ; antenuEe rufous, the basal joint of the funicle very robust, not quite as long as the second which is slender and obconical ; club densely clothed with short coarse pearly pubescence.

Length 3.7 mm. ; width 1.3 mm. Texas (Austin). The single specimen, which I took at the indicated localit}^, re- presents an interesting species somewhat allied to foveolata, but much narrower and differently sculptured toward the apex of the elytra. 4 T. contlisa n. sp. — Rather narrowly oblong-oval, strongly convex, black throughout, the upper surface rather shining but with a distinct alu- taceous lustre, almost glabrous, the squamules slender, recumbent, aggregated in two small spots on the head, one in the middle near the apex and two arranged transversely on the flanks of the pronotum, one or two very feeble spots on the disk of each elytron near basal third and in the usual transverse interrupted band at apical fourth, the squamules pale brownish in color. H(:ad and beak finely, sparsely punctate, each puncture with a small seta, the front with a short longitudinal canaliculation connecting the two squamose S230ts.

Elytra barely one-fourth wider than the prothorax, twice as long, parallel and straight at the sides in basal two-thirds, the apex parabolic ; humeri rounded to the base of the prothorax ; disk toward base with extremely large uneven semi-confluent fovese, arranged in series, becoming smaller and distant but distinct toward apex, the series there being broadly deeply and conspicuously impressed.

Plocaiiius BARIS. Germar. — Ins. Spec. Nov. 1824, p. 197. Bariclitis SchiJnh. (pars). This is a large genus of almost universal distribution, but much more developed in North and South America than in Eurasia. Assuming the definition of the genus given in the preceding table, the species occurring within the territory embraced by the present monograph are of an oval or oblong-oval convex form of body, with semi-glabrous and usually strongly shining integuments. As com- pared with most of the other genera of the tribe the sculpture is rather coarse and only moderately dense. The vestiture consists of small semi-erect or recurved sette, which are always sparse and never broadly squamiform. The rostrum is invaria))ly short, often excessively so, never quite equalling the prothorax in length, and, in many cases, not more than one-half as long. On comparing this form of beak with that of Centrinus, Limnobaris or even Onj^chobaris, it can reasonably l»e inferred that the hal)its of the species are notably, if not essen- tially, ditferent from those of the latter genera. 470 Coleopterological Notices, IV. The legs are veiy short, the tibia? strongly mueronate within at apex, and more or less strongly carinate and grooved along the sides, the tarsi moderate in development, with the third joint more or less broadly bilobed or emarginate ; the ungues are somewhat variable in length, but never very long. Our species can be readily divided into two groups, which might be considered of subgeneric value, were it not for the fact thai B. caUida constitutes a connective bond in the important character relating to the form of the scutellum. The first of these groups is characterized by a robust form of body, a greater development of the sparse setae, broadly sinuate external outline of the tibite, feebly marked transverse impression at the base of the beak, and a trans- verse broadly impressed scutellum, the other by a variable but nearly always more slender form of body, less developed setaj, straight tibiiB, strongly marked l)asal impression of the beak, and a smaller subquadrate or rounded and unimpressed scutellum. In the first, the anterior coxa? are always very narrowly separated, while in the second they are generally much more widely so, although never very remote when compared for example with Onychobaris, their distance asunder being always less than their own width. I find no appreciable difference between the groups in the nature of the impression of the prosternum, the latter being very variable in degree ; it is sometimes quite marked, but cannot well be made use of in a tabular arrangement of the species. It occasionally disap- pears completely. The buccal opening is deep, and has, at the bottom, a long slender truncate process, serving as a pedestal for the mentuni, the latter being small and obconical. In the species of the first group the sides of the buccal opening are more or less prolonged downward, forming lateral plates for the protection of the oral organs, espe- cially developed in strenua. In the second group, however, the sides of the fissure are horizontal and perfectly continuous with the flat under surface of the beak. The mandibles are small, stout, arcuate and distinctly overlap when closed. The sexual characters are more marked than in most of the other genera with exposed pygidium, the male being nearly always easily recognizable by the distinct impression at the middle of the abdo- men toward base. It is somewhat singular that this impression, in the present case, is always more sparsely and finely punctured than the neighboring surface of the abdomen, while in Blapstinus, of the (Joleopterological Notices, IV. 471 Tenebrioaida3, possessing an entirely analogous abdominal impres- sion, which might at first sight be supposed to have been developed from the same causes and for identical purposes, the impression is almost always notably more densely punctured than the surround- ing surface. The beak is not subject to great sexual modification, although there are a few exceptions to this rule, as for instance sparsa, in which it is distinctly shorter in the male than in the female. The following table probably includes a large proportion of the forms inhabiting the United States : — Tibise sinuate externally and prominent at apex ; anterior cox^ narrowly separated ; impression between the head and beak feeble ; setae more developed, generally bristling also from the under surface of the beak ; scutellum usually short, transverse and broadly, deeply impressed, nearly as in Trichobaris ; body never with seneous surface lustre 2 Tibiae straight, occasionally with a small external dentiform process at apex but never broadly sinuate ; anterior coxae more widely separated ; impres- sion between the head and beak strong but always broadly angulate when viewed in profile ; scutellum small, subquadrate or rounded, not broadly impressed; setae generally inconspicuous ; surface lustre frequently aene- ous 9 2 — Scutellum transverse and impressed 3 Scutellum small, rounded, not transverse 8 3 — Elytra at least twice as long as the prothorax, generally distinctly more.. .4 Elytra very distinctly less than twice as long as the prothorax 7 4 — Elytral intervals strongly elevated, narrow and never more than slightly wider than the grooves, the second and third generally not at all wider than the others 5 Elytral intervals broader, flat and feebly elevated, the grooves unusually shallow ; second and third intervals much wider 6 5 — Elytral callus prominent, the elytra being abruptly and distinctly wider than the prothorax and with the sides parallel in basal two-thirds.

I have been forced, however, to refer extensively to sculpture in separating and describing the species, since this is one of those enormously difficult genera containing a large number of undoubtedly distinct species — as shown by extended series, — which can only be distinguished by bodily facies, and which are devoid of prominent structural differences, but the language em- ployed should not be interpreted too rigidly, as it applies in general only to the typical forms of a species. For example, the pronotal punctuation m futilis and inconspicua is said in the table to be dense, but there are specimens of both these species before me, in which the punctures become separated by fully their own width, or what might be termed sparse. In the case of isolated specimens, therefore, a search for the proper identification in the table must be more or less tentative, and it is quite possible that the table itself may be misleading in those cases where I have had to take the characters from single specimens. It has been \\\y constant care to avoid synonymical repetitions, and, except in obvious cases, I have Annals N. Y. Acad. Sci., VI, Sept. 1892.— 32 476 " Coleopterological Notices, IV. only accepted those species whicli could be demonstrated by lavg-e series. The fact that nearly four hundred specimens have been studied in composing the table, increases my belief that the number of species at least has not been materially overestimated. Baris as here considered also occurs abundantly in Brazil, and the species taken on the banks of the Amazon and La Plata cannot be distinguished in type from our own representatives. The genus, even in its restricted sense, is therefore a very large one. The European species have a distinctly different fades and should be re- vised from the generic point of view ; the species are surely too heterogeneous to be included in a single genus. 1 Baris ingens n. sp. — Oval, rather strongly convex, intense black throughout, the integuments strongly shining. Head finely, sparsely punc- tate, with a deep frontal fovea, the impression very feeble ; beak stout, evenly and distinctly arcuate, coaisely strongly but not very densely punctate, three- fourths as long as the protliorax, the setae long and bristling beneath ; antennae rather long, the funicular joints less coarctate than usual, broad but obconical near the club, the latter large, robust, the basal joint distinctly less than one- half of the mass, transverse. Protliorax small, very nearly as long as wide, the sides in basal two-thirds rather strongly convergent and nearly straight, then broadly rounded, thence more convergent and slightly constricted to the apex, which is scarcely two-fifths as wide as the base, the latter transverse, the median lobe broad and strong ; disk with a very uneven and ill-defined median line, the punctures very coarse and deep, abruptly perforate, one-half as wide as the scutellum and generally separated by less than one-half of their own diameters, each bearing a conspicuous fine cinereous seta. Scutellum moderate, transverse, not strongly impressed. Elytra large, one-third longer than wide, nearly two and one-half times as long as the prothorax, and, at the large and longitudinally but not laterally prominent humeri, rather abruptly almost one-third wider than the base of the latter ; sides parallel and nearly straight in basal two-thirds, then gradually rounded to the apex, which is somewhat parabolic ; disk with coarse, deep, strongly and not very remotely punctured grooves ; intervals flat, one-half wider than the grooves, each with a single uneven series of moderately large, deep, close-set punctures, the setae moderate in length, slender, conspicuous. Abdomen rather sparsely punctate, each puncture bearing a long cinereous and conspicuous setiform liair, giving a strongly pruinose appearance by unaided vision. Anterior coxae approximate, separated by scarcely one-fifth of their own width ; pro- sternum not impressed. Length 7.3 mm. ; width 3 5 mm. Arizona. A conspicuously distinct species, easih' recognizaljle by its large size, small ])rothorax, ample elytra and unusually evident but slen- der setiB, especially pronounced on the abdomen. The type is a Coleopfei'ological Notices, IV. 47*7 male and has a large although moderately deep, oval impression, occupying the basal half of the abdomen. The transverse groove immediately before each posterior coxa is very wide, extremely deep, cavernous and abruptly limited anteriorly the metasternum thence to the middle coxce decidedly tumid. Ingens is more closely related to strtota than to any other of our species, the differences being expressed in the table. 2 Baris striata Say. — Cnrc. 17, Ed. Lee, I, p. 281 (Baridius). This is a rather common species of extended distribution, occur- ring throughout the Mississippi and Missouri valleys, but not, to my knowledge, extending to the Atlantic coast regions. The beak is robust, strongly arcuate and quite distinctly shorter than the prothorax, the latter relatively smaller than usual, fully one-third wider than long, with the sides feebly convergent to apical fourth, then strongly rounded and convergent to the apex, behind which there is generally a feeble constriction; the punctures are very coarse and generally separated by scarcely one-Iialf of their own widths. Scutellum transverse and broadly impressed. Elytra large, a little more than twice as long as the prothorax and abruptly nearly one-fourth wider than that part, the humeral tuberosities small but very distinct ; the stride are very coarse, deep and punc- tate and the intervals are but slightly wider than the grooves, each with a single uneven series of moderately coarse, very deep, close- set punctures, the setfe moderate in length, erect and distinct but not as conspicuous as in sfrenua. The prosternuni is not impressed in front of the coxae, and the latter are somewhat closer than in any other species which I have observed, being separated by rather less than one-fifth of their width. Length 4.8-5.5 mm. ; width 2.25-2.'! mm. The series before me is from Arkansas, Wisconsin and Montana. 3 Baris linibilicata Lee. — Proc. Ac. Nat. Sci., Phila., 1868, p. 363 (Baridius) ; Proe. Am. PhiL Soc., XV, p. 291, Of this well-marked species I have before me a series of between twenty and thirty specimens, showing great variation in size, and also in certain other more unexpected directions. The body is deep polished black throughout, robust and very strongly convex. The beak is rather long and but feebly arcuate, three-fourths as long as the prothorax in the male, and but very slightly shorter than the 478 Coleopterological Notices, IV. latter in the female. Prothorax subconical, more strongly narrowed near the apex, convex, coar.l'ica h. sp. — Oblong-oval, strongly convex, black through- out, highly polished, the lustre quite distinctly aeneous.

Prothorax large, scarcely one-third veider than long ; sides feebly convergent and very slightly arcuate to apical fourth, then strongly rounded, thence strongly convergent and nearly straight for a short distance to the apex, which is transversely truncate ; base three and one-half times as wide as the head, straight and feebly oblique from the rather wide broadly and feebly rounded median lobe to the sides ; disk with a wide but very ill defined elongate impunctate spot, the punctures moderately coarse, sparse, somewhat deep, impressed, minutely umbilicate, about one-third as wide as the scutellum and separated by nearly three times their own diameters. Scutellum somewhat large, subquadrate, slightly trans- Coleopterological Notices, IV. 483 verse. EUjtra scarcely more than one-fourth hjiiger than wide, a little less than twice as long as the prothorax, and, at the small and feehly tumid humeri, but slightly wider than the latter ; sides behind the humeri very feebly convergent, the apex broadly, almost semi-circularly rounded ; disk with moderately coarse, very deep, abrupt, finely remotely and very feebly crenulate grooves, the intervals at least twice as wide as the grooves, flat, each with a series of small, moderately distant, somewhat transversely rugu- lose punctures, which are more or less confused on the second, third and fifth ; setae small but distinct, silvery. Abdomen finely, feebly, sparsely punctured, the setse of the under surface quite robust, pale and distinct. Legs very short, robust, black, finely and sparsely punctured ; claws moderate. Length 3.7-4.5 mm. ; width 1.9-2.3 mm. Florida. National Museum. The type is a female judying- by the entirely unimpressed abdo- men, but in several of the species allied to this in general hal)itus, the male se.xual characters become very feeble, so that it is occa- sionally difficult to determine the sex of isolated individuals. The present species is widely distinct although somewhat allied to niiida ; it may be known, however, by its black legs, finer pronotal punc- tures, less rhomboidal form of the body, larger scutellum, closer and more transversely rugulose interstitial punctures, and more evident seta3. The anterior coxte are sei)arated by one-half of their own width. 11 Baris tliniesceiis Lee— Proc. Ac. Nat. Sci., Phila., 1868, p. 362 (Baridius); Proc. Am. Phil. Soc, XV, p. 292. Oblong, robust, convex, black throughout, the legs somewhat piceous, polished and feebly igneous, the beak very short, not at all over one-half as long as the prothorax in the female, the prothorax large, one-fourth wider than long, subparallel, strongly rounded and extremely convergent near the apex, the base fully three and one- half times as wide as the head, the disk without median line, the punctures rather coarse and impressed, separated by twice their own diameters. The elytra are but slightly longer than wide and two-thirds longer than the prothorax, coarsely, deeply striate, the grooves distinctly crenulate, becoming deeply and conspicuously so toward base ; intervals flat or feebly convex, scarcely one-half wider than the grooves, each with a single series of rather small but deep, moderately distant punctures, the third very much wider than any of the others and with the punctures sparse )}ut confused.

A species of medium size and distinct facies, of rather robust, very convex and subrhomboidal form and polished, feebly aeneous lustre. Prothorax not quite as elonfi;ate as in some of the allied forms, from one-third to two-fifths wider than long, the sides feebly convergent to apical fourth, then strongly convergent and straight or feebly sinuous to the apex, coarsely, very sparsely punctate, the punctures not very deep, impressed and umbilicate. Scutellum very small, nearly circulai'. The humeri are unusunlly prominent, and the elytra rather strongly convergent behind them, the stride mode- rate in width, deep, the intervals about twice as wide as the stria?, each with a single series of small but rather deep, remote punctures, not confused on the second or third, the setae very small and not at all conspicuous. The legs are red and the tarsi piceous. Length 3.9-4.4 ram.; width 2.1-2.3 mm. Florida (Biscayne Bay). I have seen but two specimens; one, the original type, in the cabinet of LeConte, and the other, entirely similar, kindly given me by Mr. W. Jiilich of New York. 13 Baris SOlllta n. sp. — Oblong, robust, convex, black and liighly polished throughout ; seise very minute and inconspicuous. Head minutely and very remotely punctulate, the transverse impression strong and angu- late ; beak exceedingly short and thick, finely, not densely punctate, arcuate, gradually ilattened toward apex, barely three-fifths as long as the prothorax ; antenna? moderate, the club small, compressed, on the narrow side scarcely at all wider than the seventh funicular joint. Prothorax transverse, fully one-half wider than long, the sides rounded and feebly convergent to apical fourtli, then strongly rounded to the apex ; base oblique and straight from the very small and feeble median lobe to the obtuse basal angles ; disk coarsely and sparsely punctate, the punctures one-half as wide as the scutellum and sepa- rated by nearly twice their own diameters, finer and closer toward apex ; ini- punctate line feebly evident. Scutellum moderate, siibquadrate. Elijtra not wider and fully four-fifths longer than the prothorax, the sides feebly conver- gent, the apex obtusely rounded ; humeri rather prominent ; striae very coarse and deep, not distinctly crenulate toward base ; intervals but slightly wider than the grooves, each with a single series of moderately large deep and some- what close-set punctures, the second and third a little wider, the latter with the series slightly uneven. Abdomen coarsely, strongly but not very densely punctate. Presternum very deeply impressed, almost sulcate, along the mid- dle, separating the coxfe by two-thirds of their own width. Length 4.0-4.3 mm. ; width 2.0—2.2 mm. Louisiana; Arkansas; Colorado. The type is a female ; this sex seems to be invariably much Coleopterological Notices, IV. 485 broader than the male and with a relatively more transverse pro- thorax. 14 Bai'is floridensis ii. sj^. — Oblong-oval, convex, polished throughout, dark piceous-brown, the pronotum blackish. Head and beak sjiarsely punc- tured, the latter extremely short, thick, moderately arcuate, one-half as long as the prothorax ; antennre normal, the club robust, with its basal joint polished. Prothorax large, scarcely more than one-fifth wider than long ; sides subparallel in about basal half, then broadly, evenly rounded to the apex, which is narrowly transverse and truncate ; base three times as wide as the head, straight and very feebly oblique from the moderately wide and rounded median lobe to the sides ; disk strongly convex anteriorly and laterally, with- out trace of median line, the punctures rather coarse, deep, well separated, subperforate with the edges slightly obtuse, two-thirds as wide as the scutel- lum and separated by nearly their own widths, becoming slightly smaller and closer toward apex. Scutellum well developed, not impressed, slightly trans- verse. Elytra scarcely more than one-fourth longer than wide, three-fourths longer than the prothorax, and, at the rather small and moderately tumid humeri, slightly wider than the latter; sides behind the humeri distinctly convergent and nearly straight, broadly rounded at apex ; disk with moder- ately coarse, very deep, abrupt, finely, remotely but distinctly punctate grooves ; intervals scarcely twice as wide as the grooves, flat, each with a single series of large shallow moderately close-set punctures, the second distinctly wider and with the punctures smaller closer and broadly confused ; setse very .small but forming quite visible series by anteriorly oblique illumi- nation. Abdomen rather coarsely but sparsely and shallowly punctured. Legs moderate, spai'sely but rather strongly punctate. Length 4.0 mm. ; width 1.8 mm. Florida. The single male serving- as the type represents a species quite closely allied to soluta, but differing in its slightly narrower form, shorter beak, less coarse pronotal punctures and several other char- acters. The abdomen is rather narrowly and very feel)ly impressed in the middle toward base; the prosternum nearly flat, very widely separating the coxa3. Floridensis may be distinguished from trans- versa by its much sparser punctuation, narrower form, piceous el3'tra and longer elytral seta3. 15 Baris SUbaenea Lee. — Proc. Ac. Nat.

Middle States. 16 Baris vespertina n. sp. — Oblong-oval, convex, polished and dark piceous-brown througliout, the setfe long, stout, acuminate, strigose, sparse but conspicuous, semi-erect and arranged without order on the elytra. Head minutely but distinctly, not very remotely punctured, the beak not coarsely but deeply, densely so, rugose at the sides, robust, moderately arcuate and about three-fourths as long as the prothorax ; antennse inserted distinctly be- hind the middle, the scape very short, club moderate, its basal joint polished, pubescent toward apex. Prothorax one-half wider than long, the sides just visibly convergent, evenly and distinctly arcuate to near the apex, then gradually more strongly arcuate, convergent and feebly sinuate to the apex, which is broadly arcuate and fully one-half as wide as the base, the latter but slightly oblique, the median lobe small but prominent ; disk coarsely deeply and very densely punctate, the punctures two-thirds as wide as the scutellum and almost in mutual contact ; median impunctate line narrow, not attaiuing the apex.

Elytra, slightly wider and nearly four-fifths longer than the prothorax ; sides behind the feebly prominent humeri slightly convergent, the apex abruptly and obtusely rounded ; stria3 moderately deep, not very coarse, the intervals fiat, nearly twice as wide as the grooves, the punctures moderately coarse, not very dense but rugose and confused on all the intervals, the second and third a little wider. Abdomen strongly, rather coarsely, somewhat closely punctured. Prosternum broadly and just visibly impressed, separating the coxae by oue- half of their own width. Length 3.3-3.5 mm. ; width 1.6-1.7 mm. Arizona. The form of the prothorax, with the pronotum more declivous anteriorly, shows that this very distinct species should be associated with transversa and its allies. In the male the abdomen is broadly and feebly but distinctly impressed near the base. Coleopterological Notices, IV. 487 17 Baris Ollloilgllla n. sp. — Dull and strongly alutaceous In lustre, oblong-oval, convex, deep black throughout, the legs slightly piceous. Head sparsely, minutely punctate, the beak more coarsely and closely so, densely rugose at the sides, short, thick, arcuate, but slightly more than one-half as long as the prothorax ; antennae moderately slender, the club rather small, not one-half as long as the funicle, the first joint of the latter shorter than the next three. Prothorax scarcely one-fourth wider than long ; sides broadly, evenly arcuate, becoming nearly parallel toward base, the arcuation only slightly stronger near the apex ; base three and one-half times as wide as the head, the median lobe rather narrow, distinct ; disk somewhat coarsely, deeply and very densely punctate, the punctures one-half as wide as the scutellum and sei:)arated by rather less than one-half their own diameters, with a narrow and distinct inipunctate median line extending from the base nearly to the apex. Scutellum moderate, transverse. Elytra scarcely more than one-fourth longer than wide, three-fourths longer than the prothorax, at the feebly tumid humeri scarcely at all wider than the latter ; sides feebly convergent and just visibly arcuate from the humeri, the apex abruptly, broadly rounded ; disk with rather fine but deep and abrupt strise, which are finely, very feebly punc- tate, the intervals each with a single row of rather large deep moderately dis- tant punctures, somewhat confused on the second, third and fifth. Abdomen strongly, rather closely punctured. Leys somewhat sparsely and feebly punc- tate ; tibipe straight externally, the tarsal claws moderate. Length 3.8 unu. ; width 1.8 mm. Colorado. The description is drawn from the male, the two basal segments of the abdomen being strongly impressed in the middle. The pro- sternum is feebly impressed and the coxte separated by rather more than one-half of their own width. This species may be distin- guished by the long, evenly rounded, strongly, densely punctate prothorax, which is subequal in width to the elytra, and by the very dull lustre of the entire upper surface. The pronotal punctures are denser, and, especially, smaller than in transversa, which oblongiila somewhat resembles in form and size. 18 Baris transversa Say. — Cure. 18, Ed.

New York, Indiana, Iowa, Missouri, Colorado and Texas. A widely distributed, common and easily recognizable species. I think that there is but little doubt that Say described transversa from one of the numerous sculptural modifications of inter stitialis, but as the species is more commonly known under the name transversa and since the name "interstitialis^' refers to a form which has never l)een accurately defined, and has always given rise to confusion and uncertainty, even on the part of Say himself, the course here pur- sued would appear to be for the best interests of science. Carinu- lata is not tenable as a species, the smooth median line of the pronotum being a most variable feature, as is also the interstitial j»unctuation. 19 Baris dilatata n. sp. — Oval to oblong-oval, robust, strongly convex, black, the beak rufescent toward apex, the legs bright rufous ; integuments rather shining, without trace of jeueous lustre.

Scutellum moderate, often moderately impressed in the middle toward the posterior margin. Elytra one-fonrth to one-third longer than wide, about two-thirds longer than the prothorax, and, at the moderately tumid humeri, quite distinctly wider than the latter ; sides subparallel or very feebly con- vergent ; apex broadly, rather abruptly rounded ; disk witli somewhat fine Coleoptej'ological Notices, IV. 489 but deep, abrupt, obsoletely punctured grooves, the intervals two to three times as wide as the grooves, flat, moderately coarsely, deeply, rather closely punctate, the punctures more or less broadly confused on all, sometimes throughout but often only toward base ; setje very small, distinct but not conspicuous.

The pro- sternum is scarcely impressed and the cuxie separated by fully three- 490 Coleopterological Notices, IV. fourths of their width, the process being unusually wide. The species is especially notable by reason of its coarsish punctuation, long prothorax and rather short subconical elytra. 21 Bai'is aprica n. sp. — Oblong-oval, strongly convex, polished and dark piceous-brown throughout, the setae small, distinct but not conspicuous. Head excessively minutely and sparsely punctulate, the transverse impression strong and angulate ; beak very short, thick, moderately arcuate, feebly flat- tened toward apex, densely but not coarsely j)un(;tate and about two-thirds as long as the prothorax ; antennal sca])e very short, the club rather robust, oval, with the basal joint polished but sparsely pubescent and constituting a little less than one-half the mass. Prothorax one-third wider than long, the sides broadly rounded and strongly convergent anteriorly, becoming almost parallel and straight in basal two-thirds ; base straight and feebly oblique at the sides, the lobe equalling nearly one-third of the width, rather prominent ; disk coarsely deeply and densely punctate, the punctures very narrowly sepa- rated, a narrow impunctate line distinct but not attaining the apex. Scutel- lum moderate, subquadrate, rugose. Elytra but slightly wider and three- fourths longer than the prothorax, the sides behind the scarcely prominent humeri just visibly convergent; apex abruptly and obtusely rounded, the sutural notch broad and deep ; striae rather coarse, deep, the intervals but slightly wider than the grooves, each with a single series of large, very deep, even and almost contiguous punctures, the third much wider than the others and with the punctures broadly confused and smaller. Abdoinen strongly but not coarsely, moderately closely punctured. Prosternum flat, densely punc- tate, separating the coxae by rather more than one-half of their own width. Length 3.4-3.6 mm. ; width 1.65-1.7 mm. Arizona ; Colorado. The coarse deep rounded and close-set punctures, forming a single series on each of the elytral intervals, is a type of sculpture which forcibly reminds us of several species of Onychobaris, such as stictica, but otherwise there is no resemblance. Aprica belongs in the group containing transversa, but is not very closely related to any other species. The abdomen in the male has a rather small but distinct subbasal impression. 22 Baris dolosa u. sp. — Oblong-oval, strongly convex, piceous-black throughout, polished, the elytra frequently feebly piceous. Head obsoletely, the beak finely, sparsely punctured, the latter quite coarsely and closely so at the sides, thick and arcuate toward base, straight and somewhat tapering in apical half, two-thirds ( "Ji ) to three-fourths ( J ) as long as the prothorax; antennae moderate, normal. Prothorax nearly two-fifths wider than long, the sides nearly parallel and very feebly arcuate to apical fourth, then strongly but moderately narrowly rounded, thence very strongly convergent and nearly straight to the apex ; base three times as wide as the head, subtransverse and Coleopterological Notices, IV. 49.1 straight, the median lobe modeiatein width hut prominent, narrowly subtrun- cate at apex ; disk with scarcely a trace of median line, coarsely, very deeply and closely punctate, the punctures one-half as wide as the scutellum or rather more, and separated by about their own diameters. Scutellum moderate, transverse. Eljtra one-fifth longer than wide, two-thirds to three-fourths longer than the prothorax, and, at the moderately pi'ominent humeri, but very slightly wider than the latter; sides subparallel, the apex broadly and ab- ruptly rounded ; disk with rather coarse, deep, obsoletely punctured grooves, the intervals scarcely one-half wider than the grooves, flat, each with a single series of coarse strong and very close-set punctures, sometimes slightly con- fused on the third ; setae small, semi-erect, cinereous and rather consjiicnous. Abdomen finely, sparsely punctured. Legs moderate, finely, very sparsely punctate. Length 3.2-3-6 mm. ; width 1.5-1.75 mm. New York (Long Island) ; Pennsylvania; Indiana; Iowa. A comparatively small, convex, strongly and deeply sculptured species bearing a general resemblance to transversa, but distinguish- able by its much smaller size and the other characters given in the table. The anterior coxse are widely separated and the prosternum feebly impressed. In the male the abdomen is narrowly and strongly impressed toward base. In the female the pronotal punctures are generally much closer, sometimes very dense, and the prothorax is frequently subprominent at apical fourth ; the above described type is a male from Iowa. 23 Baris Zimiana n. sp. — Oval, convex, highly polished and black throughout. Nedd minutely, sparse!}' punctate, the beak finely, deeply and sparsely so and not very densely at the sides, robust, short, arcuate, about three-fourths as long as the prothorax in both sexes ; antennse moderate, normal. Prothorax nearly two-fifths wider tlian long; sides convergent and broadly, almost evenly arcuate from base to apex, sometimes feebly sinuate for a short distance near the latter ; base three times as wide as the head, straight and slightly oblique from the small and feeble median lobe to the sides ; disk with or without a narrow, feebly defined impunctate line, tlie punctures rather coarse, deep, not very dense, two-thirds as wide as the scu- tellum and separated by nearly one-half their widths, somewhat uneven and noticeably smaller near the apex. Scutellum small, rather transverse. Elytra two-fifths longer than wide, about twice as long as tlie prothorax, and, at the feebly tumid humeri, slightly wider tlian the latter ; sides thence very feebly convergent, the apex broadly arcuate; disk with rather wide, very deep, ob- soletely punctate grooves, the intervals flat, generally a little less than twice as wide as the grooves, each with a single series of very coarse, somewhat uneven, close-set punctures, those of the fourth and fifth intervals leaving but a narrow margin from their sides to the edge of the grooves ; setfe small but robust and quite distinct. Abdomen somewhat strongly but sparsely Annals N. Y. Acad. Sci., VI, Sept. 1892.— 33 492 Coleopterological Notices, IV. punctured. Legs rather coarsely, deeply, moderately closely punctate ; tarsal claws moderate. Length 3.8-4.0 mm. ; width 1.8 mm. Arizona. A single pair. In the male the abdomen is strongly impressed in the middle toward base, the impressed area being more finely and sparsely punctured. The presternum is narrowly but distinctly impressed, coarsely but sparsely punctured, separating the coxos bv rather more than one-half of their width. 24 Baris opacula n. sp. — Elongate-oval, narrow, convex, deep black throughout, the legs with a feeble piceous tinge ; lustre dull. Head finely, sparsely, the beak rather finely but deeply, somewhat closely punctate, the latter arcuate, not very robust, three-fourths as long as the prothorax ; an- tennae moderate, normal, first joint of the funicle as long as the next three, club rather robust, ovoidal, pointed, not as long as the scape, the first joint partially pubescent, feebly shining. Prothorax scarcely one-fourth wider than long, the apex subtruncate, nearly one-half as wide as the base ; median lobe of the latter broad and feeble; sides broadly, evenly arcuate throughout, be- coming subparallel in basal third ; disk rather finely but very deeply and densely punctate, without median impunctate area, the punctures not quite one-half as wide as the scutellum and generally separated by less than one- half their width ; interspaces shining.

Abdomen polished, convex, rather sparsely punctate, the last segment densely so. Legs moderate, finely, sparsely punctate ; tibiae straight externally. Length 4.0-4.7 ram. ; width 1.G5-2. 1 mui. California. The prosternum is coarsely, somewhat closely punctate and very feebly impressed, and the coxai are separated by one-half their width. This is one of the most isolated species of the genus, easily identi- fiable by the opaque elytra, fine deep striae and dense pronotal punc- tures. 25 Baris porosicollis n. sp. — Not very robust, convex, oval, deep black throughout, not strongly shining. Head finely, spaj'sely punctate, separated from the beak by a wide but distinct, obtusely angulate depression ; beak rather arcuate, two-thirds as long as the prothorax, finely, closely punc- tate, more closely and very densely so at the sides ; antennae moderate, the Coleopferological Notices, IV. 493 funicle rather slender except the basal joint, which is somewliat robust and scarcely as long as the next three, club rather small, robust, tlie first joint almost glabrous, polished. Prothorax scarcely more than one-fifth wider than long ; sides feebly convergent and almost straight in basal three-fourths, then strongly rounded and convergent to the apex but not constricted ; base three times as wide as the head, the median lobe rather narrow, rounded and dis- tinct ; disk rather finely, deeply, very densely punctate, the punctures some- what uneven, one-half as wide as the scutellum and generally separated by one-third their width, a narrow imperfect median impunctate line evident in the type. Scutellum transverse, punctate. Elytra scarcely one-third longer than wide, twice as long as the prothorax, and, at the moderately tumid humeri, quite distinctly wider than the latter, broadly, obtusely rounded be- hind ; disk not very coarsely but deeply, abruptly striate, the strise with remote feeble punctures ; intervals moderate in width, the fifth twice as wide as tlie stride, flat, each with a single row of moderately large, strong, approximate punctures, confused on the second, third and fifth ; setae rather robust, short but distinct. Abdomen rather coarsely and densely punctured toward base. Legs finely, moderately closely punctate, the set?e short and silvery ; tibiae straight externally ; tarsal claws rather small. Length 4.0 mm. ; width 1.8 mm. ($). Nebraska. Easily known by its rather long and narrow, densely punctate prothorax, very close-set punctures of the elytral intervals and some- what dull lustre. The prosternum is rather deeply impressed, coarsely, moderately densely punctate, the coxjb separated by a little less than one-half their width. I place with the type three specimens collected by Mr. Wickham at Greeley, Colorado, which differ only in having a single series on the fifth interval in both n)ale and female, but which are otherwise similar throughout. 26 Baris puiictiTentris n. sp. — Oblong-oval, moderately convex, somewhat robust, polished tliroughout, black, the legs piceous. Head obso- letely punctate, the beak rather coarsely but not very densely so at the sides, rather stout but equal throughout, strongly arcuate and almost as long as the prothorax ; antennae normal. Prothorax rather short, nearly one-half wider than long ; sides subparallel and very feebly arcuate in basal two-thirds, then strongly rounded, thence strongly convergent and nearly straight to the apex, which is transverse ; base scarcely two and one-half times as wide as the head, subtransverse and straight, the median lobe small and feebly developed ; disk without median line, the punctures coarse deep and perforate, three-fourths as wide as the scutellum, rather unevenly distributed but generally separated by distinctly less than their own diameters, in apical fifth becoming abruptly very minute. Scutellum rather small. Elytra about two-fifths longer than wide, a little more than twice as long as the prothorax, and, at the very small 494 Coleopterological Notices, IV. basal and feebly tumid humeri, slightly wider than the latter ; sides behind the humeri just visibly convergent and very feebly arcuate, the apex evenly rounded, the sutural notch normal ; disk with deep abrupt obsoletely punc- tate grooves, moderate in width toward base, becoming much narrower toward apex ; intervals rather wide, flat, each with a single series of small feeble punctures, which become larger and close-set toward base but very minute and widely distant toward apex ; setje scarcely at all visible. Abdomen throughout coarsely deeply and very densely punctured. Legs moderate, the hind tibise scarcely more than two-thirds as long as the femora, straight; tarsi slender, the basal joint but slightly longer than the second ; claws small. Length 2.8-3.2 mm. ; width 1.3-1.6 mm. Louisiana ; Missouri ; Indiana. This small species can easily be identified by the peculiar punc- tuation of the pronotum and abdomen as detailed in the description. The prosternum is very feebly impressed and widely separates the coxfe. The three specimens before me are apparently females, but as they differ greatly in relative stoutness of form, it is possible that the more slender specimen from Louisiana, assumed as the t_vpe, may be a male, and that in that sex the abdominal impression is obsolete. 27 Baris rubripes n. sp. — Oblong, moderately convex, highly polished, piceous-black, the legs rufous. Head minutely, rather sparsely punctured, with a small punctiform fovea in the transverse impression, the beak strongly, moderately densely punctate, arcuate, about three-fourths ('J, ) to four-fifths ( 9 ) as long as the prothorax ; antennae somewhat less robust than usual, the fanicle long, with the second joint a little longer than wide, the third feebly transverse, club short but robust. Prothorax two-fifths wider than long, the sides almost evenly and rather strongly arcuate from base to apex sometimes a little more abriii^tly convergent near the latter ; base distinctly less than three times as wide as the head, transverse, the median lobe narrow but pronounced ; disk widest slightly before tlie base, with a rather wide distinct impunctate area which is subentire ; punctures somewhat coarse, deep and dense, about three-fourths as wide as tlie scutellum and separated by less than one-half their diameters. Scutellum unusually small, subquadrate, slightly tumid. Ehjtra two-fifths longer than wide, fully twice as long as the prothorax and not distinctly wider than the disk of the Ip-tter, the humeri feebly tumid ; sides subparallel, the apex broadly but not \terological Notices, IV. near the apex, four-fifths as long as the prothorax ; aiitennie moderately stout, the basal joint of the club highly polished. Prothorax rather transverse, nearly one-half wider than long, the sides feebly convergent to apical third, then more strongly rounded and convergent but scarcely at all constricted to tlie apex, which is about one-half as wide as the base, the latter straight and feebly anteriorly oblique from the small but distinct median lobe to the basal angles ; disk not coarsely but deeply, conspicuously and somewhat closely punctured, without trace of impunctate line, the punctures nearly one-half as wide as the scutellum and generally separated by about their own diameters. Scutellum small, quadrate, scarcely at all impressed. Elytra but little wider than the i^rothorax, about twice as long as the latter ; humeri rather promi- nent ; sides distinctly convergent ; apex obtuse ; strife moderately fine, deep, abrupt, the intervals nearly fiat, fully twice as wide as the grooves, each with a single series of fine, rather distant punctures, the second, and especially the third, much wider, the latter with the punctures confused. Abdomen finely, sparsely punctate. Prosternum strongly impressed along the middle, sepa- rating the cox£e by two-thirds of their own width. Length 3.5—4.0 mm. ; width 1.65-2.0 nun. Florida. Somewhat related to eeneomicans, but easily distinguishable by its more elongate, more finely punctate prothorax, with the sides much less rounded, and by its relatively shorter beak. 45 Baris Vitreola n. sp. — Oblong-oval, rather robust, moderately con- vex, highly polished throughout, black with a strong aeneous lustre, the elytra and legs rufo-piceous ; setse extremely minute and scarcely visible. Head just visibly and very remotely punctulate, the transverse impression moderate ; beak very stout, cylindrical, flattened toward apex, finely but strongly, rather densely punctate, strongly, evenly arcuate and almost as long as the protho- rax ; antenuc-e moderate, the club small, oval, with the basal joint polished. Protltorax lather small and transverse, fully three-fifths wider than long, the sides quite evidently convergent and nearly straight from the base to apical fourth, then strongly rounded to the apex, the constriction obsolete ; base not quite three times as wide as the head, straight and rather strongly oblique from the small and moderately prominent median lobe to the basal angles ; disk strongly and sparsely punctate, without trace of impunctate line, the punctures about two- fifths as wide as the scutellum and generally separated by rather more than twice their own diameters. Scutellum subquadrate, scarcely at all impressed. Elytra slightly wider than the prothorax and fully twice as long, oblong, the sides behind the feebly prominent humeri just visibly convergent and slightly arcuate ; apex broadly obtuse ; strise rather strong, deep, abrupt, finely punctured, the intervals fiat, fully twice as wide as the grooves, each with a single series of very fine remote punctures, the third scarcely wider tlian the others. Abdomen sparsely punctate toward the middle, rather closely so laterally, the punctures becoming large but shallow. Prosternum strongly impressed along the middle, separating the coxie by three-fifths of their own width. Length 3.4 mm. ; width 1.75 mm. Coleopterological Notices, IV, 507 Florida. The unique typo is a male, the abdomen being broadly and rather strongly impressed in the middle toward base. There is no species very closeh" allied to vitreola, but punclivenhHs appears to approach it more closely than any other. 46 Bai'is ancilla n- sp. — Oval, not very stout, convex, strongly shining, the elytra with a scarcely perceptible alutaceous lustre; body black through- out, with a feeble bluish metallic lustre ; setfe minute, extremely sparse and inconspicuous. Head excessively minutely, sparsely punctate, the beak more strongly but not very densely so, very stout, arcuate, gradually and feebly flattened toward apex, distin(;tly shorter than the prothorax ; antennje inserted a little behind the middle, the club moderate, with the basal joint polished and constituting rather less than one-half of the mass. Prothorax one-third wider than long, the sides evenly rounded and convergent in ajjical third, becoming nearly straight and parallel thence to the base, the latter twice as wide as the apex, feebly oblique at each side of the small but distinct, rounded median lobe; disk without impunctate space, the punctures strong but not coarse, about one-half as wide as the scutellum and generally separated by rather more than their own diameters. Scutellum small, quadrate, unim- pressed. Elytra slightly wider than the prothorax and nearly twice as long, the humeri but feebly prominent ; sides feebly convergent, gradually parabolic in apical third, the sutural notch strong, broadly angulate ; striae moderate, deep, even ; intervals flat, a little more than twice as wide as the grooves, each with a single series of fine feeble and remote punctures, the second and third wider but similarly punctate. Under surface and abdomen jeneous in lustre, the latter sparsely punctate. Prosternum sulcate, rather widely sepa- rating the anterior coxse. Length 3.3 mm. ; width 1.(5 mm. Florida. This species is slightly larger than confinis and differs in its much sparser punctuation; from serea it differs in its more elon- gate form, much larger size, wider elytral intervals and finer striae, and from exigua, to which it appears to be more closely allied, it may readily be known by its much finer and more remote intersti- tial punctures, longer and less rounded prothorax, with less oblique base, larger size and several other characters. 47 Baris spleudens n. sp. — B. interstitialis Lee. nee Say : Proc. Am. Phil. Soc, XV, p. 293 ; Boh, : Sch. Cure. Ill, p. 684 (Baridius)?— Oblong-sub- oval, moderately convex, black and without leneous lustre but highly polished. Head obsoletely punctulate, with an evanescent frontal puncture ; beak very robust, evenly, moderately arcuate, two-thirds to three-fourths as long as the prothorax ; antennae normal, the club rather small. Prothorax rather trans- verse, two-fifths wider than long ; sides broadly, evenly rounded and conver- gent anteriorly, becoming subparallel toward base, sometimes feebly prominent Annals N. Y. Acad. Sci., VI, Sept. 1892.— 34 508 Coleopterological Notices, IV. at apical fourth ; base not quite three times as wide as the head, straight and distinctly oblique from the very small and feeble median lobe to the sides ; disk finely but distinctly, sparsely and somewhat unevenly punctate, with a narrow, feebly defined median line, the punctures less than one-half as wide as the scutellum and separated by two or three times their own diameters. Scutel- lum small, almost circular. Elytra two-fifths longer than wide, not quite twice as long as the prothorax, and, at the feebly tumid humeri, slightly wider than the latter ; apex broadly, rather abruptly rounded ; disk with somewhat coarse, deep, obsoletely punctate grooves, the intervals Mat, generally but slightly wider than the grooves, each with a single series of minute but quite visible, remote punctures, the third interval much wider and with the punc- tures broadly diffused ; setae extremely minute, inconspicuous. Abdomen finely but rather strongly, sparsely punctate. Legs dark rufo-piceous in color, feebly and sparsely punctate. Length 3. '3—4.1 mm.; width 1.5-1.9 mm. Florida (Fernandina). Mr. Schwarz. The prosternum is rather narrowly and quite stronply subsulcate, and separates the coxas by scai'cely one-third of their own width. This is a distinct and easily recog'nizable species, but as it differs so radically from Say's description of interstitialis in the nature of the elytral punctuation, I do not think that it can be placed near that species; the latter is here regarded as being identical with transversa. In regard to Bohemau's inter stitialis, there must always be more or less doubt until the type can be compared, as there are several of these peculiar sparseh' pun2tured Florida species, which will equally satisfy his description. 48 Baris exigua. n. sp. — Oblong-oval, moderately convex, shining and piceous-black throughout. Head very minutely and obsoletely punctate, the beak rather coarsely and somewhat densely so, short, arcuate, three-fourths as long as the prothorax ; antennae moderate, normal, the first joint of the club polished and sparsely setose. Prothorax nearly one-half wider than long, widest before the base, the sides evenly, rather strongly arcuate, the apex broadly arcuate and continuous with the sides, the apical angles entirely obsolete ; base nearly three times as wide as the head, straight and slightly oblique from the feeble median lobe to the sides ; disk without trace of median impunctate area, the punctures fine but deep, not very dense, about one-half as wide as the scutellum and separated by distinctly more than their own diameters. Scutellum very small. Elytra two-fifths longer than wide, twice as long as the prothorax, and, at the feebly tumid humeri, very slightly wider than the disk of the latter ; sides behind the humeri just visibly convergent, the apex broadly rounded, the sutural notch large and quite deep ; disk with fine but deep, abrupt, finely, remotely punctured grooves, which are feebly creuulate near the base ; intervals flat, nearly tliree times as wide as the grooves, each with a single series of fine but distinct, widely spaced punc- tures. Abdomen finely, sparsely punctate. Legs rather distinctly, moderately Coleoi')terolorjical Notices, IV. 509 closely punctured ; tibire straight ; third tarsal joint not wider than long, tlie emargination extending slightly beyond basal third; claws small. Length 2.G mm. ; width 1,2 mm. ( J ). Texas (near Austin). The singular form of the prothorax, evenly rounded from the sides throughout the apex, the fine pronotal punctures, rather depressed form and small size, will readily distinguish this species. The pro- sternum is narrowly, feebly impressed, and separates the coxae by much more than one-half of their own width. The elytral setse are very minute and almost invisible under moderate power. PLESIOBARIS n. gen. The species of this genus are for the most part small, generally quite minute, and for this reason will possibly prove to be some- what numerous, especially as they are essentially characteristic of our comparatively unexplored extreme southern fauna. One or two species are known to occur in the more northern parts of the United States, but the majority will probablv be found to inhabit subtropi- cal Florida extending perhaps to Cuba. The various representatives were regarded by LeConte as forming part of the genus Pseudobaris, but certainly cannot be appropriately placed there, because of their non-sulcate prosternum, moderately separated coxas and small but perfectly free claws. They agree well together in the general nature of the vestiture, this being densely squamiform at the base of the third elytral interval, on the meso- and metasternal side-pieces, and at the sides of the last three ventral segments; elsewhere on the dorsal surface the large scales are sparse, and variously distributed according to the species. The few forms here brought to notice already fall into two groups of almost subgeneric value, which however I will simply indicate in the following table: — Basal joint of the antenna! club large, composing at least one-half of the mass ; body cylindrical, the elytral humeri not exposed ; elytra each with a large sparsely squamose area behind the middle. Black, the base of the prothorax rather strongly bisinuate; legs rufo-pice- ous ; rostrum shorter than the prothorax 1 T-signillU Piceousblack ; legs rufous, with the knees black ; base of the prothorax transverse, just visibly and broadly bisinuate ; very small species. 2 sigiiatipes Rufo-testaceous, the elytral suture clouded with black ; base of the protho- rax very broadly and feebly bisinuate; larger species 3 albilatllS 510 Coleopterological Notices, IV. Basal joint of the club short, composing one-third of the mass or even less ; elytra not continuous with the prothorax at the sides, the humeri more or less exposed and oblique ; body and legs intense black throughout. Pronotum with a regular but sparsely squamose design, the scales sparsely scattered over the elytra toward the sides, and also more or less distinctly clustered in several small spots on the third and fifth intervals. 4 aeiniila Pronotum without regular squamose design, the elytral vestiture consisting entirely of minute inconspicuous setae which become slightly more robust, but scarcely squamiform, toward the sides, and with a squamose spot at the base of the third interval 5 disjlincta 1 Plesiotoai'is T-signuiu Boh. — Sch. Gen. Cure, VIII, p. 154 (Baridius). Pennsylvania — Bobenian. There are but few statements con- cerning this species, which can be made with any degree of cer- tainty. It however undoubtedly belongs to the present genus, and is probably also a member of the olbilatas division, having the elytra cylindrical and continuous in outline with the prothorax at the sides. The omission of exact measurements of length and width is a serious defect in the great work of SchiJnherr. 2 Plesiobaris Signatipes n. sp.— Subcylindrical, convex, polished, piceous-black, the legs slightly paler, more rufous with the knees black, ves- titure extremely minute and inconspicuous with the exception of a few large, widely scattered, white scales toward the middle and sides of the pronotum, a denser lineolate spot of the same at the base of the third elytral interval, and, behind the middle, a short even row of widely spaced scales on the second, third and fourth intervals, also a few widely distant scales on the fifth inter- val ; on tlie under surface the meso- and metasternal side-pieces are densely clothed throughout with large white scales and also the last three abdominal segments laterally. Head and beak sparsely, feebly punctured, the latter moderately robust, feebly flattened toward apex, strongly, evenly arcuate and fully as long as the prothorax, the antennse moderate, the joints of the funicle slightly convex at the sides, the second and third subequal and about as long as wide, the club small, briefly ovoidal, the basal joint composing fully one- half of the mass. Prothorax one-fifth wider than long, the apex feebly arcuate and two-thirds as wide as the base, the latter transverse, the median lobe br.oad and exceedingly feeble ; sides parallel and straight to apical fourth, then rounded, thence straight and not at all constricted to the apex; disk with a rather wide but ill-defined impunctate line, the punctures rather large, one-half as wide as the scutellum but very feeble and sparse, separated by more than their own widths, becoming minute and still more feeble toward the apex, and also near the base except in the middle. Scutellum very small, subogival. Elytra barely twice as long as the prothorax and exactly equal to the latter in width, the sides straight and continuous, broadly but not Coleopterological Notices, IV. 511 abruptly romided behinrl ; humeral tuberosities very small and feeble, not at all evident laterally; disk with very fine, moderately deep strife, the inter- vals flat, four or five times as wide as the strife, the second and third sensibly wider, each with a series of minute, feeble, distant and indistinct punctures. Abdomen very minutely, obsoletely and sparsely punctured toward the middle. Prosternum flat, not sensibly impressed, separating the somewhat small coxfe by about two-thirds of their own width. Length 1.75 mm. ; width 0.6 mm. Florida (Tampa). Mr. Schvvarz. The antennal differences between this species and diyancla are very radical in the structure of the club, but I can perceive no other divergencies of a g'eneric nature, and parallel inconstancy of this kind is well known in Onychobaris. Signatipes approaches more closely to the published characters of T-aignum, than other species which I have seen, but differs in its piceous color, apparently sparser pro- notal punctures and in several other characters, among the more importnnt of which is the form of the basal line of the prothorax, said to be rather profoundly bisinuate in T-aignum. 3 Plesiobaris albilatiis Lee. — Proc. Am. Phil. Soc, XV, p. 298 (Pseudobaris). Oblong-cylindrical, convex, polished, rufo-testaceous in color, the beak, under surface, knees and elytral suture piceous-black ; punc- tures of the upper surface bearing very minute and inconspicuous setae, with a few large scattered whitish scales toward the middle and sides of the pronotum, and a denser spot of the same at the base of the third elytral interval, the remainder of the elytra with a few large widely dispersed scales arranged subtransversely, and of which a loose spot on the second and third intervals is more distinct ; meso- and metasternal side-pieces and lateral portions of the last three ventral segments abruptly very densely squamose. The beak is robust, strongly arcuate and fully as long as the prothorax, the antennie slender, the funicle long, with joints two to four a little lonuer than wide and decreasing very slightly in length, the club small, with the basal joint composing distinctly more than one- half of the mass. Prothorax one-third wider than long, the sides parallel and nearly straight to apical fourth, then convergent and constricted, the base broadly and very feebly bisinuate, the disk with a wide but uneven impunctate line, the punctures rather coarse, deep and somewhat dense. The elytra are as in signatipes, but with the intervals equal and about four times as wide as the grooves. The prosternum is broadly, scarcely perceptibly impressed 512 Coleopterological Notices, IV. anteriorly, and separates the coxae by about two-thirds of their own width. Claws small, entirely free. Length 2.2-3.1 mm.; width 0.9-1.3 mm. Florida (Tampa, Baldwin and Enterprise). The disposition of the scanty vestiture is somewhat remarkable ; for example, on the fifth interval each puncture bears a minute and simple seta, but every third or fourth puncture l)ears instead, a very large fan-shaped scale placed in a transverse position. In spite of the great differ- ence in size the present species and signatipes are closely allied. In the species of this group the scattered scales seem to be easily removable, while in semula they are exceedingly persistent. 4 Plesio1>aris aemilla. n. sp. — Snbcylindrical, strongly convex, shin- ing, deep black througliout, the vestiture consisting of short broad white scales which are large in the dense spots, but elsewhere small ; the scales are only present on the pronotum in an anteriorly dilated lateral vitta, which is pro- longed inwardly along the basal margin almost to the middle, then abruptly flexed anteriorly and outwardly as a narrow line terminating at lateral third and middle of the length ; on the elytra the scales are condensed in four small almost equidistant spots on the third interval, of which the basal is the largest, and thence to the side margins are widely but almost evenly scattered, but sometimes forming three spots on the fifth interval ; on the under surface they are very dense on the meso- and metasternal side-pieces, and at the sides of the last three ventral segments. Head and beak not very strongly punctured, the latter short, very thick, .strongly arcuate and subequal in length to the prothorax, the antennae inserted a little beyond the middle, the basal joint of the funicle short, not twice as long as wide, the second and third very short, subequal, the club about as long as the preceding six, with its basal joint composing one-third of the mass. Prothorax one-third wider than long, the sides parallel and straight in basal three-fourths, then broadly subangulate, thence convergent, nearly straight and not at all constricted to the apex, the latter truncate and two-thirds as wide as the base, the latter transverse almost straight, the median lobe subobsolete ; disk without median line, the punctures deep, moderate in size, very dense but not crowded. Scutellum very small, rounded. Elijtra more than twice as long as the prothorax and a very little wider, parallel, parabolic in apical third, very finely but deeply striate, the intervals flat, moderately wide the third and fifth much broader than the others, each with a series of small feeble rather distant punctures ; humeral tuberosities very feeble. Prosternum flat, separating the coxfe by rather more than their owu width. Length 1.6-1.7 mm. ; width 0.65-0.7 mm. Florida. Mr. E. A. Schwarz. This species was confounded by Dr. LeConte with the Zimmer- mann specimen from South Carolina, identified by him as T-signum Boh., and referred to below under disjuncta. It is a much smaller Coleopterological Notices, IV. 513 species, and is not at all allied to the form mentioned. It was apparently taken in great abundance. Among the specimens before me there is one which is singuliirlv deformed, the pronotum having, near the base and at lateral fourth, a prominent polished wart-like tubercle. For a considerable dis- tance around the tubercle, the small normal squamules are entirely absent but replaced by large scale-like plates, concave or umbilicate in the centre, each of which completely fills a puncture. 5 Plesiobaris disjuiicta n. sp. — Suboylindrical, very slender, con- vex, black throughout, strongly shining, sparsely clothed with very small setaB, especially evident but not at all conspicuous toward the sides of the pronotum, very minute and sparse throughout on the elytra, the latter with a small elongate spot of white squamules at the base of the third interval, the meso- and metasternal side-pieces and sides of the last three ventral segments also densely squamulose, the remainder of the under surface subglabrous. Head very feebly, sparsely punctate, the impression rounded, feeble ; beak shining, finely, deeply, moderately densely punctate, rather stout, cylindrical somewhat strongly, evenly arcuate, a little longer than theprothorax ; antennse moderate, the club rather large, as long as the preceding six joints combined, the latter short and coarctate. Prothorax about one-fourth wider than long, the sides feebly divergent and nearly straight from the base almost to the apex, then rounded for a short distance, the subapical constriction very small and feeble ; apex truncate, nearly as wide as the base, the latter broadly, very feebly bisinuate ; disk with moderately coarse, deep, perforate punctures which are almost contiguous, the impunctate line narrow and feebly defined, only visible toward the centre. Scutellum small. Elytra at the base abruptly quite distinctly wider than the prothorax, rather more than twice as long as the latter, the sides parallel and almost straight, somewhat abruptly, acutely ogival in apical third ; humeri obliquely rounded, the callus not conspicuous ; disk with fine strife, becoming coarse near the base, the intervals two to three times as wide as the striae, each with a single series of fine remote punctures, becoming closer and more distinct toward base. Abdomen rather strongly, coarsely and closely punctured, especially toward base. Prosternum broadly, feebly impressed, separating the coxae by quite distinctly less than their own width. Length 1.7-2.1 mm. ; width 0.6-0.8 mm. Michigan ; Missouri ; Indiana ; South Carolina. This species was considered by LeConte as possibly representing Bohenian's Baridius T-signum, but it is evidently a widely different species. The original description of T-signum includes the phrase "elytris antice thoracis basi non latiora," and also states that the rostrum is shorter than the i)rothorax, the elytra having a small sparsely squamose maculation behind the middle, and the legs rufo- piceous. One of the most conspicuous characters of disjuncta relates 514 Coleopterological Notices, IV. to tlie form of the humeri, the elytra being abruptly much wider than the base of the prothorax, and in the type there is no trace of a squamose raaculation behind the middle of the elytra, nor any indication of such a spot, as all the punctures are occupied by small slender setae. PYCIVOBARIS n. gen. In many respects this genus is allied to Baris, but its species have a distinctly different habitus due to the scaly vestiture. In its structural characters, it is similar to Baris in the form of the anten- nal club with its basal joint polished and composing fully one-half of the mass, also in its short robust beak and free tarsal claws. The fiat prosternum separates the coxfe rather more widely than in any species of Baris, and in this peculiarity it approaches Onychobaris ; the fine and abrupt frontal groove differentiates it, however, from both of these genera and allies it with Stictobaris, from which again it differs in its robust convex body and non-tubulate prothorax. The prothorax is more distinctly constricted near the apex than in Baris, but is never tubulate. The l)eak is always shorter than the prothorax, the epistomal lobe short, truncate and limited at each side by a small oblique fissure as in Baris. Mandibles well developed, arcuate, overlapping in repose and deeply notched at apex. The buccal opening is rather smaller than in Baris, and its plane is more oblique to the under surface of the beak behind it. The scutellum is quite different from that of the last-named genus being distinctly bisinuate at apex. Tarsal claws rather long, widely divergent. Our two species may be defined as follows: — Vestiture rather sparse, the whitish scales very narrow, producing merely a decided pruiiiose appearance 1 pi'lliliosa Vestiture dense, the scales broad, almost entirely concealing the surface. 2 sqtianiotecta 1 Pycilol>aris prilinosa Lee. — Proc. Am. Phil. Soc, XV, p. 294 (Baris). Robust, oblong-oval and strongly convex, black throughout, the integuments polished but clothed uniformly, although not very densely, with long narrow subrecumbent scales. The beak is robust and feebly arcuate, scarcely more than three-fourths as long as the prothorax, the antennse rather short and rol)ust, with the second Goleoptey^ological Notices, IV. 515 and third funicular joints short and equal, the outer joints very wide; and subcontinuous with the club in outline, the latter moderate, the basal joint polished and sparsely setose, constituting about one-half the mass, the remaining rings short and each abruptly and con- spicuously less in transverse diameter than the preceding. Pro- thorax one-third wider than long, the sides feebly convergent and broadly arcuate very nearly to the apex, then more convergent and broadly but distinctly constricted ; basal lobe rather narrow but very prominent, the disk with an extremely narrow impunctate line, the punctures rather small, about one-fourth as wide as the scutel- lum and distinctly separated. Scutellum slightly transverse, the posterior margin with two narrow deep notches. The elytra are but slightly more than one-half longer than the prothorax, the stria? very fine but deep, the intervals broad, flat, slightly uneven in width, finely closely and confusedly punctate throughout, and from five to six or seven times as wide as the stride. Prosternum flat, separating the coxae by a little less than their own width, nearly as in Onycho- baris, but npparently not at all foveate anteriorly. Length 3.2-4.2 mm. ; width l.G-2.2 mm. Texas and Colorado. Moderately abundant. 2 Pyciiotoaris sqiiamotecta n. sp. — Robust, ovoidal, strongly con- vex, the integuments black and polished throughout but covered densely with long wide truncate and recumbent scales of a yellowish tint. Hemi minutely, sparsely i^unctateand glabrous, the transverse groove very deep and abrupt, the beak robust, densely j^unctate and squamose but narrowly impunctate and subcarinate in the middle toward base, moderately, evenly arcuate and about three-fourths as long as the prothorax ; antennae stout, densely squamose, nearly as in pniinosa, the large basal joint of the club highly polished and having widely scattered stiB' setae. Prothorax fully one-third wider than long, the sides rather strongly convergent and feebly arcuate from the base to apical fifth, then broadly rounded but not prominent and broadly strongly constricted to the apex, the latter not at all tubulate, broadly arcuate and two-fifths as wide as the base; basal lobe small but prominent; disk with a narrow im- punctate line, indistinct before the middle, the punctures small, not much more than one-fourth as wide as the scutellum and separated by nearly one- half of their own diameter. Scutellum trapezoidal, nearly twice as wide posteriorly as at base, the posterior margin broadly, feebly bisinuate and the surface behind broadly impressed, the angles acute. Elytra, at the large but very feebly prominent humeri, only slightly wider than the prothorax, nearly two-thirds longer than the latter, the apex broadly obtuse ; disk with fine ratlier shallow striae, the intervals five or six times as wide as the striae, finely but deeply, confusedly and rather sparsely punctate throughout, the scales 516 Coleopterological Notices, IV. of the stiial punctures being exactly equal in size and form to those of the intervals. Abdomen finely, not densely punctate, the scales large and dense. Presternum flat, separating the rather large coxae by not quite their own width. Length 4.7 mm. ; width 2.4 mm. Texas. Easily distinguishable from priiinosa by the dense vestituve of lii'oad recumbent scales. A single specimen. STICTOBARIS n. gen. The few components of this genus are distinguished by a rather depressed body, extremely coarse and deeply perforate sculpture of the pronotum, and a rather short prothorax which is strongly tubulate at apex. The anterior cox* are large and somewhat nar- rowly separated. Although the prosternum is feebly impressed, a certain decided relationship with Onychobaris is- rendered evident by the two deep fovete situated near the apex. It resembles Baris in the large basal joint of the antennal club, though this is not a character of decisive generic import, but differs from both the genera referred to in the deep and abrupt transverse frontal groove or con- striction. The beak is rather short and stout, with the epistomal lobe short and broadly sinuate at apex and the mandibles somewhat well de- veloped, arcuate, notched at apex and partially decussate when closed. The vestiture consists simply of rather long sparse stout semi-erect and whitish or yellowish-white sette or setiform squani- ules, which are sometimes denser on the second to fifth elytral intervals behind the middle, a character heretofore noticed in one of the groups of Plesioljaris, and also occurring in several species of Centrinus. The three known species may be thus distinguished : — Set* moderate in length, yellowish, condensed at the base of the third interval and also on intervals two to five in a rather large area behind the middle ; body oblong ; legs rufous 1 cribrata Setae longer, more robust and whiter, not in the least condensed at the jjoints mentioned under the preceding species. Body rather robust, oblong, obtusely rounded at apex ; beak densely punc- tate; legs black 2 piinalis Body narrow, rather narrowly rounded behind ; size much smaller ; beak more sparsely punctate; legs rufous 3 subacuta Coleopterological Notices, IV. 51t 1 Stictobaris cribrata Lee. — Proc. Am. Phil. Soc, XV, p. 2i)6 (Onychobai'is}. Oblong-oval, somewhat depressed, shining, blackish-castaneous, the legs ferruginous ; setae somewhat robust, moderate in length, yellowish-white, more especially evident toward the sides of the prothorax, in a dense humeral spot and another one more elongate at the base of the third interval, also more or less distinctly denser on intervals two to five in a limited area behind the middle. The beak is robust, strongly arcuate and quite distinctly shorter than the prothorax, the antenna3 moderate, the funicle thick, the club rather robust but not large, the basal joint composing fully one-half of the mass, with the pubescence moderately dense. The prothorax is two-fifths wider than long, with the apex strongly constricted and tubulate, the median line narrow and ill-defined, and the punctures ]terforate, deep, fully three-fourths as wide as the scutellum, uneven in distribution but generally separated by nearly one-half their own diameters. Elytra distinctly more than twice as long as the prothorax, the intervals subequal, about one-half wider than the grooves, the third a little wider. The prosternum is not distinctly impressed and separates the rather large coxae by scarcely more than one-half their own width. Length 3. -3-4.0 mm. ; width 1.4-1.7 mm. Texas (Waco). Cab. LeConte. Easily recognizable by the pecu- liar arrangement of the elytral setffi. 2 Stictobaris pinialis n. sp. — Oblong, subdepresserl, shining, intense black throughout and sparsely, evenly clothed with rather long, robust, per- fectly white setae, without trace of condensation, except feebly on the anterior declivity of the humeral callosities. Head finely, very sparsely punctate, glabrous, the groove narrow and deep ; beak robust, densely and deeply punctate throughout, densely setose, without trace of impunctate line, feebly arcuatej almost as long as the prothorax in the female, but quite distinctly shorter in the male ; antennse moderate, the scape rather long, the second funicular joint but very little longer than the third, outer joints gradually very thick and subcontinuous in outline with the club, the latter moderately robust, with the basal joint constituting rather more than one-half the mass. Prothorax two-fifths wider than long, the sides subparallel or very feebly con- vergent and nearly straight to apical fourth, then abruptly, strongly rounded and almost transversely convergent to the constriction, which is very strong, the apex strongly tubulate, truncate and three-fifths as wide as the base, the latter subtransverse, the median lobe moderate, rounded and distinct ; disk with extremely narrow and imperfect impunctate line, the punctures very coarse, deep and dense, three-fourths as wide as the scutellum and more or less polygonally crowded. Scutellum moderate, slightly wider than long, 518 Coleopterological Notices, IV. impressed along the middle. Elytra slightly wider than the prothorax and distinctly more than twice as long, the humeri not prominent laterally ; sides subparallel, generally feebly arcuate, the apex somewhat obtusely rounded; disk with moderate striae, becoming coarse near the base, the intervals flat, slightly unequal, two to three times as wide as the stripe, rather finely, not densely, somewhat rugulosely and confusedly punctured throughout. Abdomen finely, sparsely punctate. Prosternum broadly and very feebly impressed, with two deep subapical fovese as in Onychobaris, but less distant ; coxae large, separated by scarcely more than one-half of their own width. Length 3.5-4.3 mm. ; width 1.45-1.8 mm. Arizona. The four specimens in my cabinet form a perfectly homogeneous series, and represent a species differing greatly from cribrata in the white pubescence, uniformly distributed and without trace of con- densation behind the middle or at the base of the third interval, also in its larger size, denser pronotal punctures and completely black bod}^ and legs. 3 Stictobaris Sllbacilta n. sp. — Elongate-elliptical, convex, shining, piceous-black, the legs rufous ; setae long, very robust, uniformly distributed and without trace of condensation at the base of the third interval or behind the middle. Head very finely, sparsely and feebly punctate, minutely reticu- late and alutaceous, the groove rather shallow but distinct ; beak somewhat coarsely but sparsely punctate, moderately strongly arcuate and subequal in length to the prothorax ; antennae moderate, the club somewhat robust, nor- mal, the second funicular joint short and but slightly longer than the third. Prothorax scarcely one-third wider than long, feebly convergent and nearly straight at the sides to apical fourth, then abruptly, strongly narrowed and tubulate, the apex truncate and fully two-thirds as wide as the base, the latter transverse, the median lobe small and rather feeble, rounded ; disk with a very narrow, incomplete and subobsolete impunctate line, the punctures nearly as in cribrata, but rather closer. Elytra one-fourth wider than the prothorax and nearly two and one-half times as long, the humeri feebly tumid, not prominent laterally ; sides parallel and feebly arcuate ; apex gradually, rather narrowly parabolic ; disk with somewhat narrow, moder- ately deep striae, becoming coarser and somewhat crenulate near the base, the intervals flat, from one-half wider than, to nearly twice as wide as, the grooves, the punctures arranged in nearly even single series, fine and remote but be- coming very coarse and rather close-set toward base, more or less confused on the third. Length 3.2 mm. ; width 1.25 mm. New Mexico (Las Yegas). Closely allied to cribrata, but well distinguished by its much narrower and more convex form, less truncate elytra, more elongate prothorax, and especially by the much longer, still more robust and Coleo2')ierological Notices, IV. 519 whiter seta3, without trace of condensed spots. In cribr-ata the third interval is not only more densely setulose, but appears also to l)e feebly elevated toward base. TREPOBARIS n. gen. The single species representing this genus is narrow, elongate- oval and subcylindrical in form, resembling somewhat a very elon- gate Aulobaris, and perhaps really allied more closely to that genus than to any other. The prothorax is more elongate and parallel than in Aulobaris, and is briefly tubulate at apex, and in antennal structure it differs from the genus in (juestion by its normally short second funicular joint and longer club, and in tarsal structure by the much smaller third joint, not wider than long though distinctly wider than the preceding. As in Pseudobaris, the prosternum is very deeply and abruptly sulcate, the sulcus being much too narrow to receive the beak, and this is another important feature distinguishing it from Aulobaris. The sulcus is of somewhat peculiar form, being moderately and gradually dilated anteriorly and narrowest at a point just before the coxae, a contour which suggests a line of development parallel with that of Aulobaris nnso. 1 Trepobaris elongata n. sp. — Elongate, subcylindrical, convex, highly polislied and deep black throughout, the setse of the upper surface excessively minute, the third elytral interval without trace of squamules at base ; setae of the under surface very small, erect. Head convex, finely, sparsely punctured, the transverse impression strong, obtusely angulate in profile ; beak rather stout, sparsely punctate, rather strongly arcuate at the base, but feebly so thence to the apex, equal in length to the head and pro- thorax in the male ; antennse moderately slender, the basal joint of the funicle long, the second not twice as long as wide, scarcely one-half as long as the first and much shorter than the next two, the club rather large, oval, densely pubescent, as long as the five preceding joints together and with its basal joint constituting but little more than one-third of the mass. Prothorax very nearly as long as wide, the sides just visibly convergent and nearly straight to apical fourth, then broadly rounded and feebly convergent to the fine apical constric- tion, the apex very briefly tubulate, truncate and fully three-fifths as wide as the base, the latter transverse, the median lobe almost completely obsolete ; disk not very coarsely punctate, without Impunctate line, the punctures scarcely one-third as wide as the scutellum and separated hy fully their own diameters toward the middle, close but not rugulose at the sides. Scutellum moderate, transverse, broadly angulate behind. Elytra at base equal in widtli to the prothorax, fully twice as long as the latter, three-fourths longer than 520 Coleopterological Notices, IV. wide, the humeri very small, rectangular, feehly tumid, not prominent later- ally ; sides very feebly convergent and just visibly arcuate from the base nearly to the apex, then rather suddenly and semi-circularly rounded ; disk with somewhat fine but deep grooves, the intervals flat, nearly three times as wide as the strise, equal, each with a single series of minute but deep distinct rounded and very remote punctures. Abdomen rather sparsely punctured. Prosternum separating the moderately small coxse by fully their own width. Lengtli 3.1-4.2 mm. ; width 1.15-1.5 mm. Texas. The type described above is a male and has a narrow elongate and distinct, but not very deep, impression near the base of the abdomen. The fifth ventral segment is broadly sinuato-truncate and one-half longer than the fourth. GLIPTOBARIS n. gen. The single species forming the type of Glyptobaris possesses many of the generic characters of Onychobaris, but differs in sculp- ture and vestiture to a marlied degree and inhabits a different geo- graphical region. It resembles Onychobaris in the structure of the beak and antennae and especially in the remote anterior coxte and broad flat prosternum, but differs distinctly in the form and extent of the post-coxal parts of the prosternum, and also, somewhat, in the structure of the mandibles. The latter are acute at apex and come together along a crenulate line, but do not at all overlap in repose ; they are straight in external outline, not at all arcuate, and when closed form an isosceles triangle. The broad prosternum has, anteriorly, two small deep foveie, widely distant, arranged transversely, and connected by a very narrow deep and abrupt groove; from each there extends poste- riorly for a considerable distance a fine deep inwardly arci^ate groove, the two being strongly convergent, the triangular space so inclosed being flat and impunctate. Just behind the coxa?, before the posterior margin of the broad prosternal process, there are two distant strongly elevated transverse tubercles, of which no trace can be seen in any species of Onychobaris, but which evince an unmis- takable relationship with Madarellus as shown under that genus. The pygidium is vertical and partially covered above by the over- hanging tips of the elytra, somewhat as in Desmoglyptus. 1 Glyptoliaris rugicollis Lee. — Proc. Am. Phil. Soc, XV, p. 297 (Onychobaris). Oval in form, strongly convex, rufo-piceous and polished. The Coleoptei^ological Notices, IV. 521 head is not punctate but minutely g-ranulato-reticulate and dull, the l)eak rather robust, very strongly arcuate and a little longer than the prothorax, densely, coarseh^ punctured at the sides. The pro- thorax is nearly one-third wider than long, with the sides evenly and broadly rounded, becoming parallel near the base, the apex not constricted but sometimes with a short prominent carina on the sides at the apical margin, the base transverse and with a very small but prominent median lobe, the disk coarsely, deeply, very densely sculptured in longitudinal irregularly vermiculate rugse, which are in some spots broken up into coarse punctures, and having a fine, more or less prominent, subentire median carina. Scutellum very small, ogival and not transverse. The elytra are strongly narrowed from base to apex, three-fourths longer and but slightly wider than the prothorax, the apex narrowly subtruncate, the disk with rather fine but deep and abrupt, remotely crenulate striae, the intervals flat, wide, finely sparsely and unevenly punc- tate, the yellowish elongate scales forming a large quadrate spot in basal three-fifths, the most prominent feature in the pattern being- two transverse bands, each consisting of tw^o uneven lunules ; else- where the vestiture is very sparse and inconspicuous. Length 3.6-4.3 mm. ; width 1.7-2.0 mm. Somewhat abundant throughout the eastern and southern Atlantic States. The specimens before me are from Indiana, Pennsylvania, District of Columbia and North Carolina. ONYCHOB4RIS. LeCoute— Proc. Am. Phil. Soc , XV, p. 294. The species of this genus are characterized in general by their excessively densely punctured, rather dull integuments, although there are numerous exceptions having the sculpture as sparse as in Baris. Onychobaris is a widely distinct and somewhat extensive genus, almost exclusively restricted to the desert regions of the southwest, where it replaces Baris in great measure; at least one species extends as far to the eastward as the Mississippi River and another is known from the true Pacific fauna, but the focal centre of the genus undoubtedly lies in the dry regions of Arizona and New Mexico. The vestiture consists of short robust semi-erect seta? as in Baris, but is often so abundant, from the density of punctuation, as to give to the surface a grayish-prninose a}>pearance. The generic characters are stated at sufficient length in the table, and there are 522 Goleopterological Notices, IV. hut few special peculiarities to which it is necessar\^ to call atten- tion at present; one of these is, however, possibly of considerable significance from an etiological point of view, and relates to the modified impression of the prosternum. The prosternum is greatly developed, rather remotely separating the coxae, and almost perfectly Hat, but, in the middle, at some distance behind the anterior mar- gin, there are two deep punctiform fovea?, moderately separated and arranged transversely. These fovete are generall}^ connected by a groove, and sometimes form the anterior limit of a more or less visible but feeble short parallel-sided impression. A still more advanced development of this peculiar modification of the remnant of the rostral sulcus, has been described under the genus Glyptobaris. In Onychobaris the beak is decidedly longer than in Baris, being generally a little longer than the prothorax, and is always strongly arcuate and more or less slender ; it is separated from the head by a transverse impression, which is always feeble and invariably al)ruptly impunctate and polished. The tarsi vary considerably in structure, the last joint being frequently as long as the first three together but generally shorter. The scutellum is transverse, never impressed, and usually more or less broadly rounded behind. The male sexual characters are feeble, the abdominal impression being invariably slight and often scarcely distinguishable. It is to be regretted that the majority of the species are still represented by unique examples, and there is consequently reason to believe that the following table contains only a small proportion of the forms inhabiting the inhospitable and comparatively unex- j»lored regions which have developed this interesting special type. I'lonotum extremely densely punctured, only rarely with trace of median im- punctate line, which is then much abbreviated 2 Pronotum less densely punctured, generally with a distinct impunctate line, entire or abbreviated, but at least occupying one-half of the total length 10 !2 — Elytral punctures more or less broadly confused on all the intervals ; body generally broader and more oblong or subrhomboidal 3 Elytral punctures forming nearly even single series on all the intervals ; body more narrowly oval and convex 6 3 — Legs, and sometimes also the beak, more or less rufescent 4 Legs and beak intense black throughout 5 4 — Body not strongly depressed, the setre moderately dense but not very long or robust.

Scutellum rather small, transverse. Elytra slightly longer than wide, nearly three-fourths longer than the prothorax, and, at the feebly prominent humeri, slightly wider than the latter ; outline behind the humeri evenly hemi-ellipti- cal ; disk with rather coarse deep grooves, the intervals nearly flat, subequal, about one-half wider than the grooves and rather coarsely, deeply, extremely densely and confusedly punctate throughout, somewhat coarsely rugulose, the setae distinct but sparse, short, subrecumbent and rather robust, those at the bottom of the grooves as large and distinct as the others. Abdomen finely, rather closely punctured. Length 3.9 mm. ; width 1.8 mm. Colorado. The unique type is apparently a female, and the species is quite distinct from any other here noted. 3 OnycIlObaris depressa n. sp. — Oblong-oval, depressed, black, the legs rufopiceous ; setae rather short but erect and hispid, broad and sub- squamiform, abundant, cinereous and conspicuous.

Prothorax one-third wider than long, the sides subparallel and nearly straight in basal three-fourths, then strongly rounded and conver- gent to the apex which is slightly constricted ; base transverse, the median lobe rather small but prominent ; disk without trace of impunctate line, but very narrowly and vaguely subcarinate along the middle, the sculpture un- even and excessively dense, consisting of closely crowded, rather coarse, very deep punctures, about one-half as wide as the scutellum, the latter small, moderately transverse, opaque. Elytra a little longer than wide, nearly four- fifths longer than the prothorax, and, at the base, rather abruptly and quite distinctly wider than the latter, the humeri but feebly tumid ; outline thence around the apex hemi-elliptical ; di?k with moderately fine, not very deep but abrupt striae, the intervals wide, fiat, alternating from two to three times as wide as the strise, finely and feebly, not very densely but unevenly and con- fusedly punctate and strongly shining.

Prothorax very large, just visibly wider than long; sides feebly convergent and nearly straight to apical fourth, then strongly arcuate and convergent to the apex, the latter not dis- tinctly constricted ; base transverse, the median lobe large and well developed, rounded ; disk with very narrow, short and ill-defined impunctate line near the centre ; punctures very small but deep, rounded and in rather close con- tact throughout, about one-fourth as wide as the scutellum. Elytra but just Coleopterological Notices, IV. 521 visibly longer than wide, about one-third longer than the prothorax, and, at the sTnal) and slightly prominent humeri, but little wider than the latter ; sides distinctly convergent, the apex parabolic ; disk very finely striate, the strife deep, abrupt, impunctate, the intervals flat, alternating slightly in width, four or five times as wide as the strise, finely, deeply, closely and con- fusedly punctured throughout but not rugose. Abdomen finely, rather densely punctate. Prosternum widely separating the coxse, the latter not quite as small as usual. Length 4.7 mm. ; width 2.25 mm. New Mexico ; Colorado. The type is probably a male, the middle of the abdomen near the base being very feebly impressed, and abruptly more coarsely and very sparsely punctured. This exceedingly isolated species may be known at once by its very finely and densely punctured integuments, rather large size, feebly rhomboidal form, large prothorax and short conical elytra. As is frequently the case in this genus, the prothorax in some specimens becomes feebly inflated, especially toward apex, a form which is however constant and distinctive in some species. 5 Onychobaris aiistera n. sp. — Moderately robust, rhomboid-oval not very convex, black throughout, very densely sculptured, the setfe cinere- ous, robust and conspicuous but not dense. Head rather finely, deeply, very densely punctate, the transverse impression feeble, indicated by a narrow polished and abruptly impunctate line ; beak densely, rugosely punctate, setulose, rather stout and broadly, evenly arcuate in basal half, becoming straight and slightly tapering thence to the apex, very nearly as long as the head and prothorax ; antennae inserted at the middle, moderately slender, the basal joint of the funicle fully as long as the next three, second obconical, but slightly longer than wide, three to seven transverse, club oval, pubescent, with the basal joint large. Prothorax two-fifths wider than long, the sides feebly but distinctly convergent and straight from the base to apical third, then gradually, evenly rounded and convergent to the small but evident sub- apical constriction, the apex transversely truncate and much less than one- half as wide as the base, the latter transverse, the lobe constituting a little more than one-third of the entire width, rounded and prominent ; disk very deeply and densely punctate, without trace of impunctate line, the punctures somewhat coarse. Scutellum moderate. Elytra at the small but prominent humeral callus much wider than the prothorax, three-fourths longer than the latter, a little longer than wide, broadly hemi-elliptical in outline ; disk with distinct but not very deep striae, tlie intervals flat, slightly unequal, about twice as wide as the grooves, coarsely, confusedly, closely and rugosely punc- tured throughout but shining. Abdomen rather coarsely and deeply punctate, the punctures well separatcid. Prosternum fla', the coxse very reniote. Length 3.3 mm. ; width 1.7 mm. 528 Coleopterological Notices, IV. California (San Diearis argufa n. sp. — Oblong-oval, rather strongly convex, shining, black throughout, the setse very small, slender and inconspicuous. Head finely, rather sparsely punctate, the impression feeble, polished ; beak rather stout, evenly cylindrical and arcuate throughout, densely, deeply, not coarsely but rugosely punctate and quite distinctly shorter than the prothorax ; antennae rather slender, inserted just behind the middle, the first funicular joint fully as long as the next tliree, the second obconical, one-half longer ihan wide, three to seven feebly transverse, the former nearly as long as wide. Prothorax one-third wider than long, the sides parallel and nearly straight to apical fourth, then rather abruptly, strongly rounded, thence convergent and feebly sinuate to the apex ; base transverse, broadly bisinuate ; disk rather convex, evenly, closely, not finely punctate, the punctures rounded, deep, about two-fifths as wide as the seutellum and generally separated by about one-half of their own diameters ; impunctate line obsolete. Seutellum rather small. Eljjtra slightly wider than the prothorax and from one-half to three- fifths longer, distinctly longer than wide, hemi-elliptioal, the humeri mode- rately prominent ; strije not very coarse, somewhat shallow but abrupt, the intervals slightly unequal, generally nearly twice as wide as the grooves, flat, smooth, each with a single series of deep punctures which are moderately large and rather distant, but becoming coarse and close-set toward base. Abdomen rather finely but strongly punctate. Prosternum flat, the anterior coxse rather large, separated by one-fourth more than their own width. Length 2.65-2.8 mm. ; width 1.2-1.3 mm. California (foot-hills of the southern sierras). Mr. 11. C. Fall. This species is not closely related to any other but should be associated with audax ; it differs from ambigua and egena in its black legs and in several other characters as stated in the table. In general form it somewhat resembles pavperella. 530 Coleopterological Notices, IV. 9 Onycliobaris aildax n. sp. — Oblong, strongly convex, shining, tlie elytra feebly alataceous, brownish rufous throughout, the elytra blackish, setse very small, distant and forming even single lines on the elytra. Head toward apex and beak finely but densely punctate, the latter moderately slender, evenly, somewhat strongly arcuate and rather longer than the pro- thorax ; antennje slender, second funicular joint but little longer than the third. Prothorax about one-fourth wider than long, the sides straight and somewliat divergent from the base to apical fourth, then strongly rounded and subprominent, thence very strongly convergent to the apex which is minutely and visibly constricted ; base transverse, the median lobe rather narrow but prominent, rounded, constituting less than one- third of the width ; disk with but the feeblest traces of a short median line, the punctures very deep, mode- rately small, one-third as wide as the scutellum, very dense, almost in mutual contact but circular and not polygonally crowded. Scutellum moderate, trans- verse. Elytra about one-fifth longer than wide, two-thirds longer than the prothorax, and, at the small feebly tumid humeri, but just visibly wider than tiie disk of the latter ; sides for a short distance behind the humeri parallel, then elliptically rounded through the apex ; disk with rather nar- row, deep and finely, remotely but distinctly punctate grooves, the intervals flat, subequal, about twice as wide as tlie goooves, each with a single series of somewhat small, feeble, rather remote and subtransverse punctures, slightly confused toward base especially on the fifth. Abdomen rather finely, not densely punctured. Length 3.0 mm. ; width 1.4 mm. California (southern). A small and easily recognizable species, having the prothorax rather wider at apical fourth than at base, and with the sides straight. It is also somewhat aberrant in coloration. 10 Onycliolbaris Stictica n. sp. — Oblong, not very robust, strongly convex, black, the head and beak feebly rufescent, the legs paler, rufous : integuments polished, moderately densely sculptured. Head finely, sparsely punctured, the punctuation obsolete toward base, the feeble transverse im- pression broadly impunctate and polished ; beak moderately stout, rather feebly, evenly arcuate, fully as long as the prothorax, strongly, densely punc- tate, with a narrow impunctate and subcarinate median line ; antennse normal, the second funicular joint slightly longer than the third. Prothorax: rather elongate, scarcely one-fourth wider than long, the sides parallel and nearly straight to apical fourth, then broadly, evenly rounded and strongly conver- gent to the apex, which is quite distinctly constricted ; base transverse, the median lobe very broad, distinct ; disk without distinct trace of median line ; punctures rather small, circular, deep, dense but not quite in actual contact and scarcely one-fourth as wide as the scutellum. Scutellum well developed, transverse.

Abdomen polished, rather coarsely strongly and moderately closely punctured. Legs moderate; basal joint of the tarsi as long as the next two, the third small, but slightly wider than the second, the fourth much shorter than the three preceding together ; claws small. Prosternum very widely separating the coxse. Length 3.3 mm.; width 1.6 mm. Arizona (Benson). Mr. G. W. Dunn. Somewhat similar to svblonsa in general outline, but in scarcely any other character. The seta^ of the elytra in subtonsa are very small, subrecumbent and not conspicuous, while in utictica they are unusually long, erect and form even bristling single series on each interval ; the indistinct punctures of the grooves also bear smaller setae which are, however, visible under moderate power. The punctures of the pronotum are a little less dense along the middle. 11 Oliycliobaris mystica n. sp.— Oblong-oval, convex, extremely densely sculptured, opaque, piceous-black, the head, beak and legs rufous, the setae short but erect, rather stout, distinct and somewhat dense. Head strongly, densely punctate toward apex, the transverse groove distinctly im- pressed and very highly jjolished, abruptly impunctate, the beak moderately densely punctate, very densely so at the sides, the median impunctate line distinct and entire, strongly, evenly arcuate, equal in length to the prothorax in the male, quite distinctly longer in the female ; antennje moderate, the second funicular joint rather long, scarcely twice as long as wide but subequal to the next two. Prothorax rather long, scarcely one-fourth wider than long, the sides snbparallel in basal three-fourths, then strongly rounded and con- vergent to the apex which is broad, truncate and distinctly constricted at the sides ; base subtransverse, the median lobe large, rather more than one-third the total width, prominent, broadly rounded ; disk without trace of median line', the punctures moderately coarse, nearly two-fifths as wide as the scutel- lum, deep, excessively dense and polygonally crowded throughout. Scutellum rather small. Elytra a little longer than wide, barely one-half longer than the prothorax, and, at the small but distinctly prominent humeri, quite noticeably wider than the latter ; outline behind the humeri broadly hemi-elliptical ; disk with abrupt deep coarse and confusedly punctured grooves, the intervals flat, narrow, subequal, exactly equal in width to the grooves and each with a single series of large, very deep, circular, perforate and very close-set punc- tures, which are almost as wide as the intervals. Abdomen rather coarsely, densely punctured. Length 3.3^.1 mm. ; width 1.4-1.9 mm. Arizona (Benson and Pinal IMts.) — Dunn and Wickham ; Texas (El Paso), Mr. Dunn. Very easily separated from cither pauperella or ambigua, which 532 Coleopterological Notices, IV. it somewhat resembles in general outline, by its coarser and still more closely crowded and opaque sculpture, coarser, deeper, more perforate and much more even interstitial punctures, coarser grooves and narrower intervals, and by its decidedly larger size. It is represented by a series of nine specimens, exhibiting scarcely any variation 12 Oliycllo1)aris egeiia n. sp. — Oblong-oval, convex, very densely sculptured but rather strongly shining, black, the prothorax beneath with a piceous tinge ; head, beak and legs bright red ; setse small, sparse and incon- spicuous ; those arising from the punctures of the elytral strife about as long as those of the intervals. Head shining, rather finely, deeply punctured, the punctures separated by about their own widths ; impression rather strong ; beak somewhat stout, evenly, moderately arcuate, feebly tapering toward apex, shining, rather coarsely, deeply but not very densely punctate, about as long as the head and prothorax ; antennae inserted at the middle, the basal joint of the funicle scarcely as long as the next three, second fully three-fourths longer than wide, third to seventh increasing in width, the former nearly as long as wide, the latter strongly transverse, club rather small and narrow, not abrupt. Prothorax one-fourth wiiier than long, the sides straight and just visibly divergent from the base to apical third, then broadly rounded to the small but distinct constriction ; apex very briefly tubulate, truncate and dis- tinctly more than one-half as wide as the Itase, the latter rather deeply bi- sinnate ; disk without trace of impunctate line, deeply, rather coarsely and extremely densely punctate, the punctures three-fifths as wide as tlie scutel- lum, rounded but in mutual contact. Scutellum slightly transverse. Elytra short, scarcely visibly wider than the prothorax and about one-half longer, hut slightly longer than wide, parabolic in outline, the humeri very slightly prominent ; disk coarsely, deeply striate, the intervals subequal, narrow, not distinctly wider than the grooves, each with a single even series of very coarse deep rounded and close-set punctures. Abdomen deeply, rather coarsely, moderately closely punctured. Prosternum narrowly and just visibly im- pressed in the middle, the coxse moderate, remote, separated by much more than their own width. Length 2.7 mm. ; width 12 mm. Arizona (Pinal Mts.). Mr. H. F. Wickham. A small species belonging to a group in which the species become rather closely allied. It perhaps approaches jjauperella more nearly than any other form here noted, but differs in its shorter elytra, with smaller and less conspicuous sette and much coarser more close-set interstitial punctures, and also in the coarser punctures of the head and pronotum. From o.mbigua it differs in its smaller size, narrower form, much shorter, less visible setae and narrower, more coarsely, closely and evenly punctured intervals. Coleopterological Notices, IV. 533 13 Onycliobaris ambigtia n. sp. — Oblong, convex, piceous-black and rather dull throughout, the head, beak and legs obscurely rufescent ; sculpture very dense: setre ratlier long, erect, forming conspicuous bristling series on the elytra. Head near the apex and beak finely but strongly, very densely punctured, the transverse impression feeble and only narrowly and imperfectly impunctate ; beak rather slender, evenly, strongly arcuate, scarcely at all tapering, equal in length to the prothorax, the median subcariniform line almost obsolete ; antennse moderate, the second funicular joint fully one- half longer than the third. Prothorax scarcely more than one-fourth wider than long, the sides parallel and straight nearly to apical fourth, then evenly, strongly rounded but not prominent, thence strongly convergent and nearly straight to the apex which is not distinctly constricted ; base transverse, straight, the median lobe rather small but rounded and prominent ; disk with barely a trace of an impunctate line, rather finely, deeply, extremely densely punctate throughout, the punctures scarcely one-third as wide as the scutel- lum, circular and not polygonally distorted. Scutellum moderate. Elytra not longer than wide, barely two-fifths longer than the prothorax, and, at base, rather abruptly a little wider than the latter ; outline thence hemi- elliptical ; disk with not very coarse, moderately deep striae, the intervals flat, subequal, nearly twice as wide as the striae, not very coarsely but deeply, closely punctate, the punctures forming somewhat uneven single series on each. Abdomen moderately closely punctured. Length 2.8-3.0 mm. ; width 1.35-1.6 mm. Arizona. A somewhat small species, closely allied to pauperella, but easily distinguishable by its larger size and more robust form, also by its shorter elytra, not only actually but relatively to the prothorax ; the sides of the latter are parallel in basal three-fourths in this species, but feebly convergent toward base in basal two-thirds in pavpei^ella, the widest part of the disk in the latter being at apical third. The prothorax is longer in amhigua, and the elytral inter- vals wider. It is represented by four specimens, one of which is contained in the collection of the National Museum, and was prob- ably collected by Mr. Morrison. 14 Onyclio1)aris pauperella n. sp. — Oblong, suboval, convex, feebly shining, black, the head, beak and legs dark rufo-piceous ; setae moderately long, distinct and forming rather conspicuous single series on the elytra. Head finely, rather sparsely punctate toward apex, the beak densely punctured at the sides, rather thick, equal in length to the prothorax, feebly tapering from base to apex, evenly and strongly arcuate ; antennje moderate, the second funicular joint but slightly longer than the third. Prothorax nearly one-third wider than long, the sides feebly divergent and nearly straight to apical third, then gradually broadly rounded and convergent to the apex, which is minutely and scarcely visibly constricted ; base transverse and 534 Coleopterological Notices, IV. straight, the median lobe small but prominent, broadly rounded ; disk slightly wider at apical third than at base, evenly, strongly convex, without trace of median line, the punctures rather small but deep, one-third as wide as the scutellum, very dense and even throughout but circular and not in actual contact. Scutellum moderate, ^/^ira about one-fifth longer than wide, one-half longer than the prothorax, and, at the rather small but somewhat prominent humeri, quite distinctly wider than the latter ; outline behind the humeri hemi-elliptical, the sides distinctly convergent : disk coarsely, deeply striate, the intervals sometimes feebly alternating in width, slightly, to fully one-half, wider than the grooves, each with a single somewhat uneven series of coarse, deep, close-set and subrugulose punctures. Abdomen moderately closely punctured. Prosternum separating the rather large coxse by one-fourth more than their own width. Length 2.3-2.8 mm. ; width 1.0-1.2 mm. Arizona. This is one of the smallest species of the genus, somewhat resem- bling audax in outline, but with narrower, much more coarsely closely and roughly punctured elytral intervals, and differing also in its entirely black body and more broadl}^ rounded sides of the prothorax anteriorly. Four specimens. 15 Oiiyclio1>aris seriata Lee. — Pac. R. R. Expl. and Surv., Ins., p. 58; Proc. Ac. Nat. Sci., Phila., 1868, p. 363 (Baridius); Proc. Am. Phil. Soc, XV, p. 296. The smallest species of the genus and very distinct from an}' other which I have observed. It is unusually narrow and parallel, moderately convex, black and polished, the beak rather robust, moderately and evenly arcuate and slightly longer than the protho- rax, the antennae normal in structure, the basal joint of the funicle not as long as the next four and the second but very slightly longer than the third. The prothorax is nearly as long as wide, parallel on the sides to apical fourth, then broadly rounded and convergent to the apex, which does not appear to be at all constricted; there is but feeble trace of a short median line and the punctures are deep, about one-third as wide as the scutellum and separated by nearly their own widths toward base, but nearly contiguous toward apex. The elytra are much longer than WMde and about two-thirds longer than the prothorax, finely but deeply and abruptly striate, the inter- vals flat, subequal, about three times as wide as the grooves and each with a single series of very minute distant punctures, each bearing a scarcely distinguishable seta ; the striae become quite coarsely crenulate very near the base. Length 2.3 mm. ; width 0.8 mm. Coleopterological Notices, IV. 535 This is the only Onyehobaris which has been discovered in the true Pacific fauna. It is represented by the unique type in the IjcConte cabinet, said to have been taken near San Francisco. 16 Onyclioliaris reinota n. sp. — Oval, strongly convex, not very- robust, black with a piceoiis tinge, the integuments smooth and alutaceous, minutely and densely granulato-reticulate, sets very minute and short. Head tinely but strongly punctate anteriorly, the transverse impunctate line mark- ing the feeble impression foveate in the middle ; beak finely but deeply, densely punctate tliroughout, with a fine median impunctate line, rather stout, stronglj"^, evenly arcuate, not more than four-fifths as long as the pro- thorax ; antennae normal, the second funicular joint fully one-third longer than the third, the club rather large, evenly ovoideo-fusiform, pointed, moderately abrupt. P)-ot/iorax rather h)ng, scarcely one third wider than long, the sides subparallel or extremely feebly convergent to apical fourth, then strongly rounded and convergent to the apex which is subtubulately constricted ; base transverse, the median lobe broad, strongly, evenly rounded and prominent; disk with a narrow but well marked and subentire median line, the punctures abrupt, perforate, rather deep, not very dense, separated by distinctly less than their own widths and about one-third as wide as the scutellum, slightly smaller near the median line. Scutellum moderate, trans- verse. Elijtra parabolic behind the humeri, quite distinctly longer than wide, one-half longer than the prothorax, and, at the small and feebly prominent humeri, but slightly wider than the latter ; disk not very coarsely but deeply and abruptly striate, the intervals subequal, fiat, about one-half wider than the grooves, each with a single series of rather coarse, subtransverse and dis- tant punctures. Abdomen not very densely punctured. Length 3.7 mm. ; width 1.7 mm. Texas (El Paso). The type appears to be a male, the abdomen being very feebly flattened and more sparsely punctured in the middle near the base, while the type of dutans is apparently a female ; but the two forms differ so greatl}^ in bodily form and otherwise, that I regret to believe there is but little doubt of their mutual distinctness. Remota diff'ers from distans, irrespective of the shorter beak which may possibly be a sexual character, in its more elongate-oval form, in its much less transverse, more coarsely and pronouncedly more densely punctured prothorax, with narrower median line, and in its longer and more coarsely striate elytra. 17 Onycbobaris distans Lee. — Proc. Ac. Nat. Sci., Phila., 1868, p. 363 (Baridius) ; Proc. Am. Phil. Soc, XV, p. 296. A distinct species, moderate in size, somewhat robust and convex, oblong-oval, black, with the integuments feebly shining, alutaceous 536 Coleopterological Notices, IV. and very minutely grannlato-reticulate. The beak is somewhat stout, strongly but not very densely punctate, except at the sides toward base where it becomes somewhat rugulose, strongly, evenly arcuate, barely as long as the prothorax, the antennae normal, with the second funicular joint but slightly longer than the third, the club rather large, elongate, ovoidal, pointed and moderately abrupt. Prothorax two-fifths wider than long, the sides parallel and feebly arcuate to apical fourth, then strongly rounded and convergent and feebly sinuate to the apex, the base broadly bisinuate, the disk with a broad fusiform impunctate line, the punctures rather small, scarcely more than one-fourth as wide as the scutellum laterally, abrupt and perforate, rather sparse and separated by much more than their own widths, becoming a little smaller, more feeble and still sparser toward the median line. Elytra parabolic, but slightly longer than wide, one-half longer and just visibly wider than the prothorax, not very coarsely but deeply and abruptly striate, the intervals flat, subequal, more than twice as wide as the stride, each with a single series of somew^hat small but distinct, subtransverse and very remote punc- tures, each bearing an extremely short but rather robust seta not projecting beyond its limits. The prosternum very widely separates the small anterior coxse, and has, near the apex, a small feeble par- allel-sided impression, ending anteriorly in two small punctiform foveae. Length 3.4 mm.; width 1.6 mm. New Mexico. The type in the cabinet of LeConte is, as far as known, still unique. 18 Onychobaris molesta n. sp. — Oval, strongly convex, shining, black with a piceous tinge, the head, beak and legs rufous ; setae very minute and inconspicuous. Head obsoletely and sparsely punctured even anteriorly, the feeble impunctate impression with a small deep median fovea ; beak strongly, evenly arcuate, moderately stout, fully as long as the prothorax, minutely, rather sparsely punctured, the punctures larger and rather close at the sides ; antennae normal, moderate in length. Pi-ot/iorax moderate in size, not at all inflated, scarcely more than one-fourth wider than long ; sides feebly convergent and slightly arcuate from the base, more convergent near the apex, the latter constricted and broadly but briefly subtubulate ; base broadly bi- sinuate, the median lobe rounded and more prominent than the sides ; disk somewhat convex. Scutellum transverse. Elytra one-fifth longer than wide, about two-thirds longer than the prothorax, and, at the small but distinctly prominent humeri, a little wider than the latter; sides convergent, the apex parabolic ; disk with coarse deep and abrupt grooves, the intervals flat, equal, scarcely one-half wider than the grooves, each witii a single series of very Coleopterological Notices, IV. 537 large deep rounded, rather close-set punctures which are but slightly irregular on the third. Abdomen sparsely punctured, but, as usual, densely so at the sides. Length 4.0-4.5 mm.; width 1.8-2.1 mm. Arizona. In one specimen the prothorax is inflated and apparently a little wider than the elytra. Two specimens. 19 Oliyclioliaris illex n. sp. — Rather narrowly oval, strongly convex, polished, the pronotum feebly alutaceous, black, the head, beak and legs rufous ; setse very minute, sparse and inconspicuous.

Scutellum transversely lunate. Elytra slightly wider than tlie prothorax and barely two-thirds longer, hemi-elliptical, distinctly longer than wide, the humeri small bat decidedly prominent ; disk with rather fine, moderately deep, abrupt striae, the intervals flat, from two to tliree times as wide as the grooves, sparsely but very unevenly punctate, the punctures rather fine and feeble, more or less transverse, arranged in nearly even single lines on some intervals and more or less confused on others. Abdomen finely, not densely punctate, the last three sutures very deeply excavated except at the sides. Prosternum flat, with a small transverse groove and two short parallel longi- tudinal folds anteriorly, the coxae small and very remote. Length 3.4 mm. ; width 1.6 mm. Colorado. The single specimen before me represents a species rather closely allied to molesta, differing in its more slender form and in the much finer, sparser and transverse punctuation of the elytra, also very noticeably in its much larger pygidium, the types of both of these species being females. 538 Coleopterological Notices, IV. 20 Onycliobaris pectorosa Lee. — Proc. Am. Phil. Soc, XV, p. 29.5. Broadly ovate, black and polished throughout, sparsely sculp- tured, the setae very minute and only just observable. The beak is strongly arcuate and thickened toward ba.se, but nearly straight in apical half, equal in leng-th to the prothorax and sparsely punctured. The prothorax is nearly one-half wider than long, the sides parallel and straight in basal half, then broadly, evenly rounded and conver- gent to the apex which is extremely feebly constricted at the sides; base transver!>e, the lobe equal to one-third the total width, rounded and prominent; disk rather finely, sparsely punctate, with a narrow subentire median line, the punctures scarcely one-fourth as wide as the scutellum, separated by nearly their own widths toward the middle, very dense at the sides but somewhat uneven in distribution throughout. The elytra are but .slightly longer than wide, one-half longer and very little wider than the prothorax, the sides nearly straight and unusually strongly convergent, the apex rather nar- rowly rounded; disk with somewhat coarse, very deep grooves, the intervals alternating slightly in width, from two to three times as wide as the grooves, with rather small but deep, not very close-set ])anctures, somewhat confused on the wider, but larger and in single series on the narrower, intervals. The antennge and prosternum are normal in structure. Length 3.8 mm.; width 1.95 mm. Represented by the unique type in the cabinet of LeConte, taken by Belfrage in Texas, probably at Waco. It is not at all closely allied to any other described species.' 21 OliycllObaris dilUta n. sp. — Oval, moderately convex, black and strongly shining throughout, the antennae piceo-rufous ; sculpture not very dense. Head minutely, sparsely punctate toward apex, the transverse pol- ished impression rather pronounced ; beak slender, strongly arcuate toward base, very feebly so toward apex, distinctly longer than the prothorax and sj^arsely punctate ; antennae moderate, basal joint of the funicle nearly as long as the next four, second but slightly longer than the third, outer joints rapidly shorter, becoming strongly transverse and coarctate, club normal but rather large. Prothorax somewhat more than one-third wider than long, the sides parallel in basal two-thirds, then broadly rounded and convergent to the apex which is distinctly subtubulate ; base straight and feebly, posteriorly oblique from the rather small but strongly rounded median lobe to the sides ; disk with narrow median impunctate line in basal half, the punctures deep, rounded, rather small, not quite one-third as wide as the scutellum, very dense and contiguous toward the sides but })ecoming narrowly separated near 1 Specimens possibly of this species are just received from St. Louis, Mo.

Abdomen densely punctured, especially toward the sides. Length 2.6 mm. ; width 1.2 mm. Texas. This small species is not closely allied to any other which T have been able to study. The t^'pe is apparently a female and is unique. 22 Onycliobaris porcata n. sp. — Oblong-suboval, rather convex, l)lack; throughout ; integuments polished but deeply and closely sculptured ; setse very short and inconspicuous. Head finely, rather sparsely punctured throughout, separated from the beak by a transverse impunctate line, the impression almost obsolete; beak densely, strongly punctured, evenly, rather strongly arcuate, but very slightly longer than the jirothorax, gradually but feebly tapering from base to apex ; antennae rather short, the second funicular joint l)nt slightly longer than the third, the outer joints rapidly wider, the seventh as broad as the base f)f the club, the latter short, oval, not at all abrupt, densely pubescent, with tlu^ basal joint but slightly less than one-half the mass, and with a transverse polished fovea at base on the anterior side. Prothwax rather short, nearly one-half wider than long, the sides subparallel and feebly arcuate in basal three-fourths, then strongly rounded, thence strongly convergent and feebly sinuate to the apex ; base transverse, the lobe one-third the total width, strong, rounded ; disk extremely deeply, rather coarsely punctate, the punctures not quite in actual contact but very dense, about one-half as wide as the scutellum, rather uneven in distribution ; median impunctate line narrow but distinct, not attaining the apex.

A series of Conoprodus quad ripust ulatus Fab. (quadriplagiatus Lac), taken by Mr. H. H. Smith on the Amazon near Santarem, shows clearly that Lacordaire's type of Conoproctus is the male. In the female the form, sculpture and coloration throughout are similar, but the beak is not so long, more arcuate and tapering, with the antennfe shorter and inserted near the middle, the pygidium being broadly rounded, oblique and perfectly normal. These sexual differences are extraordinary, but are evinced in an unmistakably parallel and, as far as the beak is concerned, almost equally striking manner in another Brazilian species, from the same collection and not yet identified, but which, from its general habitus and simple male pygidium, must be assigned to Madarus. Finally, in Madams hiplagiatus, which I also have liefore me, the same sexual differences are observable but to a very slight degree, the antennte being in- serted near apical third in the male and just bej'ond the middle in the somewhat shorter beak of the female; quadripustulatus is how- ever the only species in which the pygidium is affected sexually. It is quite evident, therefore, that hiplagiatus and quadripuslu- latus must be placed in the same genus, and I would suggest that these species be included under the name Conoproctus Lac, and that the name Madarus Sch. be reserved for those species mentioned by Lacordaire (Gen. Col., VJI, p. 257), as forming a second section of Madarus, and having as types vortivosus and migrator. Both Conoproctus and Madarus, as thus limited, have the femora un- armed, and I have here proposed the genus Madarellus, to include those species having the prothorax short, broad, very abruptly and strongly constricted at apex, and the femora armed beneath with a minute spiculiform denticle. It differs further from Cono- proctus in having the posterior lobe of the prosternum broadly eniarginate or subtransverse, with the lateral angles acute and not broadly rounded as in that genus, in having a post-apical prosternal fovea with short parallel folds of the surface, and a small triangular scutellum, truncate at base and not large, short and broadly lunate as in Conoproctus. The anterior coxfe, it should be added, are much more remote and rather smaller than in the latter genus. In Madarellus the beak is about one-half as long as the body in the female, evenly, distinctlv arcuate, slender, the impression sepa- rating it from the head being almost completely obsolete and the Goleopterological Notices, IV. 541 epistomal lobe not at all advanced, very broad with the lateral fissures extremely small, the mandibles well developed, each with two deep notches at apex, feebly arcuate and not overlapping when closed but forming a small triangle. Antenna^, normal, the first funicular joint as long as the next four, the second but slightly longer than thg one- fourth of the total length; disk with a rather wide and subentire impunctale line, the punctures very distinct, deep, sparse, with large impunctate areas laterally, rugulose at the sides. The elytra are about one-fourth longer than wide, twice as long as the prothorax and a little wider than the latter at the somewhat prominent humeri ; striae very fine but deep and abrupt; intervals flat, very wide and almost impunctate, the punctures of the single series being remote, very feeble and scarcely visible. Abdomen extremely densely punc- tate toward the sides. Length 2.8 mm.; width 1.3 mm. Easily distinguishable by the rather broad form, with short par- allel-sided prothorax and somewhat thicker beak.

Head opaque ; beak shining, rugulosely punctate at the sides, rather slender, moderately arcuate and fully one-half longer than the prothorax in the female, distinctly shorter, more arcuate and a little stouter in the male ; antennae nearly as in sesostri.i. Prothorax short, nearly two-thirds wider than long, the sides strongly convergent and nearly straight to apical third, then broadly rounded and more convergent to the broad and subtubulate apex, the latter not more than one-half as wide as the base ; disk with scarcely a trace of impunctate line, the punctures very fine, sparse and irregularly distributed, forming longitudinal rugse at the sides. Scutellum very small, rounded. Elytra two-fifths longer than wide, nearly two and one- half times as long as the prothorax, and, at base, a little wider than the latter ; humeri longitudinally tumid and somewhat prominent ; sides behind them feebly convergent and nearly straight, the apex abruptly rounded ; disk with extremely fine but deep abrupt grooves and wide flat subimpunctate intervals as in ater, the grooves finely, reinotely punctate at the bottom. Under surface and abdomen toward the sides very densely punctate but not very dull in lustre. Length 3.0-3.3 mm.; width 1.3-1.6 mm. Pennsylvania; Maryland; Nebra^-ka. This species is allied to sesoatria, having an entirely similar struc- ture of the prothorax, beak and antennse, but is larger, still more highly polished especially toward the sides of the upper surface, intense black in color and with relatively longer elytra, the protho- rax, also, is shorter and broader, with the sides more rapidly con- vergent from the base, and the tubulate apical portion is shorter, less abrupt and much narrower when compared with the l)asal width. The pronotum is more finely punctate and devoid of im- punctate line, but .occasionally has a small impressed fovea at the centre of the disk. The two specimens from Maryland have the elytra dark castaneous but do not otherwise differ. Sixteen exam- ples.

Elytra one-fourth longer than wide, a little wider than the prothorax and not distinctly more than twice as long as the latter, striate and subimpunctate as in ater. Under surface, except along the middle of the abdomen, and also the legs throughout deeply, densely punctate and opaque. Length 2. "7 mm.; width 1.2 mm. The two specimens in my cabinet are from Illinois, and are not as large as the type measured by LeConte (3.0 mm.). DESMOGLYPTUS n. gen. This genus is closely allied to Pseudobaris and has the prostcrnum deeply and abruptlv sulcate throughout its length, the anterior coxa^ being somewhat remote and separated by fully their own width. The beak, antenna?, tarsal claws and scutellum are also nearly as in Pseudobaris, but the other characters are so different that the unique species cannot be appropriately associated with the mem- bers of that genus. The general appearance and elytral sculpture are essentially un- like anything else in the present tribe which I have been able to study, but it is possible that the Baridius crihratus of Boheman may be somewiiat similar, or perhaps even congeneric. The form of the body reminds us strongly of Copturus, and the opaque sur- face, deep impressed and strongly crenulate strioe, with narrow and convex intervals, together with the unusually prominent subapical unibones, are a combination of characters apparently isolating the genus widely from its allies. It should be stated, however, that the peculiar outline is feebly suggested in Pseudoharia angusta. Desmoglyptus differs from Pseudobaris radically, also, in the for- mation of the pygidium and elytral apices, the latter being deeply and vertically truncate or deflexed, covering a large part of the pygidium, which is small, vertical and flat. In Pseudobaris the pygidium is large, convex and prominent, the el3^tra being normal at apex and leaving it conipletel}' exposed. In Desmoglyptus the third tarsal joint is abruptly very large, but not quite as wide as Coleopfei'ological Notices, IV. 551 long, the emargination being unusually deep; the basal node of the; fourth joint is distinct and a little longer than wide. The single species is described below; it has comparatively little affinity with Ampeloglypter, where it was provisionally placed by LeConte. 1 Desmoglyptus creiiatus Lee. — I'roc Am. Phil. Soc, XV, p. 300 ( Aiupf loglypter) . Very narrow, subcylindrical, pale red-brown throughout and densely opaque, the setae not distinct. Head rather convex, minutely, obsoletely punctate, the beak ecjual in length to the prothorax in the male, robust, strongly, evenly arcuate, feebly flat- tened toward apex, obsoletely punctate, the antennte inserted well beyond the middle, normal in structure, the first funicular joint as long as the next three, two to seven equal in length, the outer gradually slightly wider, the club oval, about as long as the pre- ceding five joints together, pubescent, with the basal joint constitut- ing much less than one-half the mass. Prothorax nearly as long as wide, the apex broadly subtubulate, the sides parallel and straight in basal two-thirds; apical margin feebly arcuate and three-fourths as wide as the base ; disk without impunctate line, the punctures rather coarse, deep and dense. Scutellum small, rounded. El3^tra three-fourths longer than wide, a little wider than the prothorax and about twice as long as the latter, the humeri slightly promi- nent; sides parallel in basal three-fifths, broadly sinuate behind the humeri, the apex narrowly subtruncate; disk of each strongly um- bonate or callous in the middle near apical fourth, the striae coarse deep and impressed, remotely but strongly crenate, the intervals narrow, convex, each with a single series of remote minute and excessively feeble punctures, which are scarcely at all observable under moderate power. Abdomen not densely punctate, with a very large broad and deep basal impression in the male; in this sex the thickened posterior edge of the fifth segment is deeply, transversely excavated opposite the apex of the pygidium, and from the bottom of this excavation there projects a small, short and transverse polished tubercle. Length 2.7-8.0 mm.; width 1.0 mm. The two specimens before me are males and one of them is labeled "Arizona." LeConte gives Virginia and Maryland as the habitat of his types. 552 Coleopterological Notices, IV. PSEVDOBARIS. LeConte— Proc. Am. Pliil. Soc, XV, p. 297. In geographical distribution this distinct genus coincides with Baris and is well represented in Brazil. The species within our territories are much less numerous than those of Baris, and are usually of a narrower and more cylindrically convex form. Some, however, are robust, but are then more oval and ellipsoidal and less oblong than in the genus referred to. The generic characters have been given in the table and need not be repeated at the present time. One of the most striking peculiarities of the genus is the deep, abrupt, parallel-sided and subimpunctate prosternal sulcus. The fact that the sulcus should be so well developed and abruptly defined at the sides in most of the species, when it can fulfill no function as a shelter for the beak, because of the robust form and much greater lateral dimensions of the latter, might be regarded as a proof that the Barini are simply cryptorhynchs which have become modified through changed habits or some other altered environment, and, that under their influence, the beak and mesosternal epimera have become modified with comparative rapidity. The prosternal sulcus, being a long established and extremely permanent structure, would survive in an essentially unaltered state for a long period after all need of it had disappeared. The species known to me may be distinguished by the following characters : — Elytral vestiture uniform, generally short and sparse. Elytra with a small condensed pubescent spot at the base of the third interval. Pronotal punctures sparse, the impunctate line obsolete. Large species, robust, piceo-testaceous in color 1 farcta Moderate in size, rather robust, black throughout, polished, without trace of aeneous lustre, the pronotal punctures and elytral striae coarse and deep ; intervals not carinate toward apex.. .2 llictliosa Pronotal punctures much closer. Body elongate-oval, rather alutaceous in lustre, median impunctate line of the pronotum narrow and distinct but not quite entire. 3 discreta Body broadly oblong-oval, highly polished, the median line obsolete. 4 fausta Elytra without basal condensed spot on the third interval. Form more broadly oval ; interstitial punctures large, deep, rounded and conspicuous, esi^ecially toward base. Coleopterological Notices, IV. 553 Larger species, very broadly oval and subdepressed, dull in lustre; elytral grooves coarse, the set?e very minute 5 pectoralis Smaller, more elongate-oval, highly polished, the elytral strise much less coarse, the setie longer, semi-erect and quite conspicuous. 6 liigubris Form slender, cylindrical, the interstitial punctures small, feel)le, remote and transversely subrugulose 7 aiiglista Elytral vestiture consisting of very small inconspicuous seta; and long wiiitH widely dispersed squamules.

Ac. Nat. Sci. Phila., ISUS, p. 362 (Baridius) ; Proc. Am. Phil. Soc, XV, p. 297. A conspicuous species, the largest of the genus, of a broadly evenly oval, very convex form, dark piceo-rufous color and polished integuments. The beak is evenly but rather feebly arcuate, robust, becoming rapidly thin and flattened near the apex, slightly shorter in the male than in the female, and, in both sexes, distinctly shorter than the prothorax ; the antennte are normal, with the second funi- cular joint one-half longer than the third. The prothorax is nearly one-half wider than long, the sides convergent and broadly arcuate from base to apex, broadly and distinctly constricted near the latter, the constriction being evident and more densely, rugosely punctate almost entirely across the dorsal surface ; base transverse, the median lobe small but very prominent; the disk is coarsely but not very densely punctate, without impunctate line. Elytra quite distinctly wider, and fully three-fourths longer than the prothorax, hemi- elliptical, the disk with rather coarse deep and abrupt grooves, the intervals flat, scarcely twice as wide as the grooves, the second and third much wider, the punctures rather large, moderately deep, not very close-set and distinctly transverse, forming single series on each, but sparsely confused on the second and third. The anterior coxfe are separated by their own width, the prosternum before them narrowly deeply and abruptly sulcate. Length 4.7-5.0 mm.; width 2.4-2.6 mm. 554 Goleopterological Notices, IV. Texas, three specimens ; Kansas and Colorado — LeConte, '1 PseildObaris llictuosa n. sp. — Rather broadly, almost evenly oval, strongly convex, intense black and highly polished throughout. Head minutely, sparsely punctate, the transverse impression rather strong ; beak densely punctate only on tiie sides behind the antennae, somewhat tumid above at base, strongly, evenly arcuate, slender and nearly one-third longer than the prothorax in the female, rather thicker and but very slightly longer than the latter in the male; antennae moderate, the second funicular joint unusu- ally long and subequal to the next two together. Piothoiax short, nearly one- lialf wider than long, the sides broadly arcuate and convergent anteriorly, gradually becoming parallel toward base, the apex broad, truncate, tubularly but very briefly produced ; base transverse and straight laterally, the median lobe one-third the total width, rounded and decidedly prominent ; disk strongly convex, coarsely, very deeply and rather sparsely punctate, the punctures fully one-half as wide as the scutellum and separated by their own widths or more.

Elytra twice as long as the prothorax, and, at the feebly tumid humeri, scarcely perceptibly wider than the latter ; outline hemi-elliptical ; disk with coarse, very deep, not distinctly punctate grooves, the intervals subequal, about one-third wider than the grooves, each with a single series of shallow, rather remote and transversely subrugulose punctures ; setae not at all visible except a small spot of white squamnles at the base of the third interval. Under surface somewhat sparsely punctured. Length 3.5-3.7 mm. ; width 1.7-1.8 mm. Florida (Cedar Keys). This species is named anthracina Boh. in many cabinets, and was placed in Aulobaris by LeConte (Proc. Am. Phil. Soc, XY, p. 289), but is evidently not the species described under that name in the work of Schonherr. The phrases " thorax postice longitudine fere latior," for a strongly transverse prothorax, and " [thorax] supra fere planus . . . evidenter crebre . . . punctatus," for a strongly convex, coarsely and sparselv punctate modification of this part, and "elytra . . . thoracis . . . dimidio longiora," for fullv twice as long, will not at all answer for this insect. As no allusion to a pygidium is made in the original description, it is possible that Baridius anthracinus Boh. may be a species of the genus Limno- baris, but we shall probably never know definitely until the type can be consulted. 3 Pseildobaris discreta n. sp. — Elongate-oval, strongly convex, black throughout and rather shining, the prothorax duller and alutaceous ; setae small, subrecumbent sparse but quite visible, not intermixed with longer squamules but larger and coarser and forming a more or less distinct spot at the base of the third and fifth intervals.

Prothorax barely one-fifth wider than long, the sides sub- parallel in basal two-thirds, then strongly rounded and convergent to the apex, the later strongly constricted and subtubulate ; base transverse, the median lobe very small but prominent, scarcely rounded and rather cuspiform ; disk with narrow ill-defined non-entire impunctate line, the punctures deep, one- third as wide as the scutellum, dense but narrowly separated. Elqtru two- fifths longer than wide, fully twice as long as the prothorax and a little wider than the latter, the humeri slightly prominent, the sides very feebly conver- gent ; apex somewhat abruptly and obtusely rounded ; disk with moderately fine deep strise, the intervals subequal, flat, about twice as wide as the grooves, each with a more or less uneven single series of moderately large but shallow, sul)transverse, somewhat close-set punctures. Abdomen i-ather closely punc- tured. Prosternura abruptly, deeply sulcate, the sulcus extending deeply nearly to the posterior limits of the coxfe, the latter separated by about their own width.

Lugubris is the only species with which the present can be com- pared, but there are many radical points of difference. \n fausta the form of the body is much broader, and the punctuation through- out very much coarser, with but the feeblest trace of a narrow and partial impunctate line on the pronotum. The prosternal groove is rather narrow, much deeper and more sharply defined in lugubris, and, in the latter, there is no condensed spot at the base of the third interval. 5 Pseudobaris pectoralis Lee. — Proc.

Prothorax rather short, nearly one- half wider than long, the sides strongly convergent from base to apex and broadly, dis- tinctly arcuate, sometimes feebly prominent near apical third and feebly constricted subapically, the disk with a narrow ill-defined impunctate line, the punctures coarse, deep, not very dense and unevenly distributed. Elytra a little wider than the prothorax, fully twice as long, a little longer than wide and hemi-elliptical behind the humeri, the disk coarsely, deeply grooved, the intervals fiat, subequal throughout and about one-half wider than the grooves, the punctures somewhat coarse, deep, close and more or less con- fused, larger and generally forming a more even single series on the fourth and occasionally, also, on the second and sixth intervals. The prosternum is deeply and abruptly sulcate, the sulcus becoming shallow and coarsely punctate between the coxse which are separated by about their own width. Length 4.3 mm.; width 2.1-2.2 mm.

A rather small species, resembling nigrina in outline, but with smaller, feebler interstitial punctures and devoid of scattered squam- ules ; from angusta it is at once distinguishable by its much more broadly oval form. The smallest and narrowest specimen before me is a female, the largest a male. Four specimens. I have united with this species a still siiialler specimen from Te.xas, which differs in its slightly coarser and very dense pronotal punctures and scarcely larger but much deeper interstitial punc- tures; it possibly represents a distinct species. 7 Pseildobaris angusta Lee — Proc. Ac. Nat. Sci., Phila., 1868, p. 363 (Baridius); Proc. Am. Phil. Soc, XV, p. 298; P. angustida Lee, ibid. p. 420. Oval, subcylindrically convex, rather polished, deep black through- out. The beak is slender, evenly, rather strongly arcuate and equal in thickness from base to apex, just visibly longer than the protho- rax in the male, but nearly one-third longer than that part in the female, the antennae normal, with the second funicular joint about one-half longer than the third.

The setae of the elytra are small, sparse, inconspicuous and unmixed with long dispersed squamules, and by this means, as well as its more slender form, angusta can be separated at once from nigrina. The change of name proposed by Dr. LeConte is unnecessary, as Pseudobaris is a genus so widely separated from Baris, that there cannot be a plausible possibility of its supi)ression. 8 Pseildol»aris nigrina Say — Cure, p. 31 ; Ed. Lee, I, p. 295 (Bari- dius). A very common and widely distributed species, occurring over the entire extent of the United States. It is moderately robust, oval, strongly convex, black and polished throughout, the beak strongly, evenly arcuate, slender and about one-third longer than the prothorax in the female, but stouter and only equal to the latter in the male. The prothorax is fully two-fifths wider than long, the sides broadly arcuate and convergent anteriorly, gradually becom- ing parallel in basal half, the apex feebly constricted at the sides ; base transverse, with a very small but prominent median lobe, the disk very deeply and densely punctured, with a narrow, more or less incomplete impunctate line, the punctures rather coarse, about one-half as wide as the scutelluni and almost in mutual contact.

Prosternum normally and abruptly sulcate. Length 2.5-3.5 mm.; width 1.0-L6 mm. I have before me a series of over seventy specimens, from all parts of the country, from New York and Florida (Key West), to Coleopterological Notices, IV. 559 California (Lake Co.). The interstitial punctures sometimes become very coarse, deep and approximate, but I can perceive no such departures of structure as might call for a division into distinctly defined subspecies. 9 Pseildobaris caelata n. sp. — Rather broadly oval, moderately con- vex, polished, intense black throughout. Head finely, distinctly punctate toward apex, the beak coarsely, deeply, subrugosely so at the sides, evenly but not very strongly arcuate, robust, gradually flattened through apical half, short, in the female barely equal in length to the prothorax, and in the male distinctly shorter ; antennse moderate, the second funicular joint about one- half longer than the third. Prothorax rather short, nearly one-half wider than long, the sides subparallel and nearly straight in basal three-fourths, tlien strongly rounded and convergent to the apex, which is broad, truncate and very briefly subtubulate ; base broadly, deeply bisinuate ; disk without trace of median line, coarsely, rather densely, very deeply punctate, the punc- tures regular, abrupt and perforate, circular, three-fourths as wide as the scutellum and separated by much less than one-half of their own diameters. Scutellum small, transversely oval, rough, not distinctly impressed. Elytra about one-fourth longer than wide, nearly twice as long as the prothorax, and, at the distinctly tumid humeri, a little wider than the latter ; sides distinctly convergent behind the humeri, the outline hemi-elliptical ; disk not very coarsely but deeply grooved, the intervals flat, equal, about twice as wide as the striae, each with a single series of moderately distant, coarse, transversely rugose but not very deep punctures ; setae very minute and not distinct, but mingled with long white widely dispersed squamules, distinctly condensed at the base of the third interval. Abdomen rather sparsely punctate, the setae of the under surface sparse but distinct, white. Presternum broadly, abruptly but moderately deeply sulcate, the coxae small and separated by much more than their own width. Length 2.6-2.8 mm. ; width 1.2-1.3 mm. New Mexico (Albuquerque). Mr. Wickhara. A very distinct species, not at all closely allied to any other but assignable to the mg7-ina group, which is distinguished by the widely dispersed white squamules of the elytra. The male has the abdomen narrowly and distinctly impressed toward base. Four specimens. IIESPEROBARIS n. gen. A single small species thus far alone represents this genus, which is allied rather closely to Pseiidobaris. It agrees with Pseudobaris in general habitus, but differs in several important structural modi- fications of the under surface, relating especially to the form of the prosternal impression and intercoxal process, also in the structure of the antennae. The antennas are of the same general type as the 560 Goleopterological Notices, IV. peculiar form distinguishing Rhoptobaris and Orthoris. The pygi- dium beneath emarginates the fifth segment in a rather deeply sinu- ous arc. In Pseudobaris the fifth segment is much less sinuate, the pygidium being but slightly visible from beneath, but in Microbaris, the latter is gradually, transversely tumid inferiorly and largely visible behind the fifth segment when viewed from beneath. 1 Hesperol)aris suavis n. sp. — Oval, very convex, shining, black tlirongliout, the legs rnfo-piceous ; setae extremely short, visible but not con- spicuous, not intermixed with dispersed squamules ; sculpture rather dense. Hfad rather deeply and somewhat closely punctate, strongly convex, the trans- verse impression broad but strong, impunctate ; beak moderately arcuate, slender, densely punctate at the sides, a little longer than the prothorax ; an- tennre moderate, the first joint of tlie funicle longer than the next three, the second exactly equal to the third, and both slightly transverse, joints two to seven cylindrically coarctate and gradually wider, club elongate-oval as long as the six preceding joints together, densely pubescent throughout, the basal joint one-third the mass and not quite as long as the second. Prothorax but very slightly wider than long, the apex nearly three-fourths as wide as the base ; sides feebly convergent from base to apex and feebly arcuate, the apex very obsoletely constricted ; base transverse, the median lobe small and ex- tremely feeble, almost obsolete ; disk with a very narrow ill-defined impunc- tate line, the punctures somewhat coarse, very dense, deep, one-half as wide as the scutellum and very narrowly separated. Scutellum small, transversely oval. Elytra one-fourth longer than wide, twice as long as the prothorax and one-fourth wider than the latter ; sides almost straight and parallel in basal three-fifths, then convergent, the apex narrowly subtruncate ; humeral tuber- osities almost obsolete ; disk with not very coarse, abrupt but shallow, opaque grooves, the intervals fiat, subequal, scarcely twice as wide as the grooves and each with a single series of rounded close-set punctures, which become coarse and deep toward base but gradually very fine toward the apex. Abdomen coarsely, deeply punctate toward base, more finely so behind, the punctures moderately dense. Length 2.4 mm. ; width 1.05 mm. Texas (Austin) ; Missouri. The type of this interesting species is a female. The specimen from Missouri is a male, and has the prothorax a little shorter and the elytral sculpture decidedly stronger. MICROBARIS n. gen. Another genus allied to Pseudobaris, necessitated by a minute species which I took some years since at Galveston, Texas. In general facies it is quite distinct from either Pseudobaris or Hespe- robaris, but the small claws, connate at base, declare its relationship with these genera. (Joleopierological Notices, IV. 561 The anteniife are somewhat peculiar. They are slender, the joints of the fanicle becoming but slightly wider toward apex, and with the club very small, of imperfect development and probably possess- ing less than the ordinary degree of sensitiveness ; the several joints are not defined by distinctly traceable sutures, and the vestiture is coarse and somewhat sparse, although tolerably uniform through- out. 1 Microliaris $;alTestoilica n. sp. — Subcylindrical, strongly-convex, polislied, black throughdut. Head minutely, the beak rather coarsely and densely punctate, the latter subimpunctate toward apex and broadly along the middle, slender, evenly, strongly arcuate and about two-fifths longer than the prothorax ; antennae slender, scape short, inserted behind the middle, funicle slender, the joints coarctate and but slightly transverse toward apex, the first not as long as the next three, the second and third subequal and each dis- tinctly longer than wide, the fourth not at all wider than long, club small, elongate-oval, compressed, sparsely pubescent and rather shining, as long as the preceding four joints together, its structure not distinct. Prothorax fully two-fifths wider than long, the sides broadly, strongly arcuate in basal half, becoming strongly convergent and straight but not in the least constricted toward apex, the latter one-half as wide as the base, feebly arcuate ; base transverse, the median lobe broad and very feeble ; disk wider at basal third than at base, with a very narrow ill-defined impunctate line, the punctures moderately large, about one-half as wide as the scutellum and dense but not polygonally distorted. Scutellum very small, rounded. Elytra one-half longer than wide, a little more than twice as long as the prothorax and very slightly wider than the disk of the latter, cylindrical in basal two-thirds, then gradually, parabolically rounded, the humeral tuberosities obsolete ; disk with extremely fine but deep and abrupt impunctate strife, the intervals flat, subequal, four or five times as wide as the strise, each with a singe series of very minute remote and feeble punctures, each bearing a small but distinct subrecumbent silvery seta. Abdomen not very finely, strongly but rather sparsely punctured. Legs short, moderately slender. Length 1.6 mm. ; width 0.65 mm. Texas (Galveston), A single specimen, the sex of which is somewhat doubtful. TRICHOB4RIS. LeConte— Proc. Am. Phil. Soc , XV, p. 287. The genus defined under this name by LeConte is one of the most highly specialized of the present group of Barini. It is not at all closely allied to Pseudobaris, although assigned at the present time to the section containing that genus because of the similarity in structure of the tarsal claws; these differ somewhat, however, in being occasionally slightly unequal in length. It has no special 562 Coleoplerological Notices, IV. affinity with Rlioptobaris. The squamose vestiture so higlily de- veloped in the Centrini is also one of the most characteristic features of Trichobaris, g-iving it a peculiar and easily recognized aspect among the semi-glabrous genera with which it must be associated, for it is easily distinguishable from Pycnobaris by its oblong form. The elongate parallel outline of the body is however not peculiar to this genus, being exhibited equally well in Stictobaris. In Trichobaris the prosternum is broadly and feebly impressed along the middle and narrowly separates the coxa3, the formation of these parts being nearly as in Biris. The scutellum is large, strongly transverse, broadly, deeply impressed and with the sides acutely angulate, occasionally being prominent and more or less reflexed toward apex or corniform, a development especially char- acteristic of the present genus, although suggested rather strongly in the first section of Baris. The vestiture consists of broad scales, sometimes both above and beneath, but often replaced by long slender squamules on the upper surface; they are always recumbent and often subdenuded in vari- ous limited areas, especially in two small spots at the base of the pronotum, in two large subconfluent areas at the sides of the pro- thorax beneath, and, in mucorea, also in three small spots at the base of the beak ; these spots are not really denuded, but are clothed with smaller and more slender piceous-black squamules. On the abdomen there is always a large subquadrate area more or less completely glabrous, occupying the median portions of the two or three last segments; this is independent of the sex of the individual. The antennal club varies in structure nearly as in Plesiobaris, enabling us to group the species as follows: — Antennal club moderately large, much longer than wide, with the basal joint constituting less than one-half of the mass ; vestiture variable but with the squamules always oblique at the sides of the elytral intervals ; body generally subdepressed above, the prothorax always more or less quasi- denuded beneath at the sides. Vestitnre of the upper surface consisting of slender squamules, which do not completely conceal the sculpture. Pronotum simply punctate, without impunctate and subcarinate median line; antennal club robust and abrupt 1 triiiotata. Pronotum densely and continently punctate, sometimes longitudinally rugose, the sides more or less feelily sinuate just behind apical third ; antennal club more slender and elongate, less abrupt, the outer funicu- lar joints more transverse ; pronotum with a narrow impunctate median carina; size larger, the vestiture denser 2 mucorea Coleopterological Notices, IV. 5G3 Vestiture consisting of large, broad, moderately dense scales ; punctures of the pronotum large, deep, circular and distinct, with a narrow carinate impunctate line ; basal denuded spots not distinct 3 insolita. Antennal club more robust and conoidal, shorter and with the basal joint constituting one-half of the mass ; vestiture consisting of more or less broad scales, more densely placed, not conspicuously oblique at the sides of the elytral intervals ; body more convex, the prothorax never with sub- denuded spots at the sides beneath. Abdominal impression of the male normally clothed with long recumbent scales ; body very robust ; basal denuded spots of the pronotum large and distinct 4 COinpacta Abdominal impression of the male bristling with erect robust and pointed hairs ; body narrow and subcylindrical ; basal subdenuded spots of the pronotum almost completely obsolete. Antennal club robust, much wider than the outer joints of the funicle ; anterior coxae separated by about one-third of their own width ; elytral striae indicated by narrow partings of the vestiture 5 texaiia Antennal club exceedingly small, scarcely wider than the outer joints of the funicle ; anterior coxae separated by one-half of their own width ; elytral striae totally obliterated by the vestiture, the latter excessively dense and composed of much broader scales ; body still narrower.

Oblong, parallel, moderately narrow, black throughout, rather dull in lustre and uniformly clothed with long fine hair-like recum- bent squamules, pure white in color, but rather sparse and produc- ing merely a grayish pruinose appearance, the scales at the sides of the elytral intervals strongly evenly and posteriorly oblique. Beak densely punctate, fully as long as the prothorax in the male, a little longer and rather slender in the female, the antennal club robust, oval, densely pubescent, as long as the five preceding joints in the former sex, but a little shorter in the latter, the basal joint but slightly more than one-third the total length, the second funicular joint one-half longer than the third. The male is generally larger than the female, and, in both sexes, the median parts of the third and fourth ventral segments are abruptly denuded. The prosternum is rather narrowly but distinctly impressed along the middle, the anterior coxa^ being separated by about one-fourth of their own width. Length 3.0-4.4 mm. ; width 1.2-1.75 mm. Pennsylvania to Florida (Key West), Illinois, extending south- 564 Coleopterological Notices, IV. ward to Texas. There is considerable doubt iu my mind as to tlie real identity of the Mexican species described by Boheman as vestita with the true trinotata of Say, the species are mutually so similar that they are liable to be confounded unless carefully compared. Plumbea Lee. seems to be identical with this species. 2 Ti'icliobaris niucorea Lee. — Proc. Ac. Nat. Sci., Phila., 1858, p. 79 (Baridius). Much larger and broader than triuotata, the vestiture rather more robust and much closer but not extremely dense, white, the squam- ules long and slender, directed transversely on the pronotum and oblique and interlacing along the sides of the elytral intervals, be- coming large and reddish-yellow along the anterior margin of the pronotum, broad and overlapping beneath and replaced by very slender dark piceous squamules in a large spot involving almost the entire flanks of the prothorax beneath, and in three small spots at the sides and on the upper surface of the beak near the base, these areas appearing as if denuded ; abdomen abruptly denuded at the middle of the third and fourth segments. Head glabrous; beak densely squamulose, the antenna? stout, with the second funicular joint longer than wide and one-half longer than the third, club rather large, elongate, conoidal, extremely densely clothed with fine short piceous hairs, the basal joint constituting one-third of the mass. Anterior coxa? separated by one-third of their own width. Male with the abdomen broadly, feebly impressed in basal half, the vestiture of the impression unmodified, consisting of large closely recumbent scales ; fifth segment with a short broadly rounded apical lobe at the middle. Length 5.0-0.0 mm. ; width 2.3-2.(j mm. Southern and Lower California and Arizona. Differs very widely from Irinotata, but perhaps identical with Boheman's vestita. It is recognizable at once by its rather depressed upper surface, large size and the subdenuded area at the sides of the prothorax beneath. Two of the specimens before me are smaller, with the vestiture decidedly sparser, and with the pronotum strongly, longitudinally rugo.se, and another much larger, with coarse and distinct pronotal rugae, but with the vestiture den.ser than usual; this is therefore an exceptionally variable species, or else I have confounded several very closely allied forms, which cannot be advantageously studied with such small series of specimens. Coleoi^terological Notices, IV. 565 3 Tl'icliobaris insolita n. sp. — Oblong-oval, somewhat robust and distinctly depressed, black tlnougliout, the integuments polished when de- nuded but densely clothed with large broad recumbent whitish scales. Head polished, glabrous, minutely, sparsely and obsoletely punctate, the transverse impression strong and normal ; beak only moderately robust, evenly, rather strongly arcuate, abruptly very strongly bent at base at the junction with the head, deeply punctate, squamose especially at tlie sides, fully as long as the prothorax in the female ; antenufe rather slender, the scape but slightly shorter than the funicle, the second joint of the latter much longer than wide and one-half longer than the third which is quadrate, fourth a little wider than long, outer joints but slightly thicker, the club small but longer than wide and rather abrupt, conoidal, densely clothed with robust recumbent cinereous squamules, tlie basal joint constituting a little less than one-half the mass. Prothorax short, about one half wider than long, the sides sub- parallel or very feebly convergent and nearly straight to apical third, then broadly i-ounded and moderately convergent but scarcely at all constricted to the apex, which is fully one-half as wide as the base, transversely truncate ; base broadly bisinuate ; disk with a narrow entire cariniform impunctate line, the punctures round, deep, perforate moderately large and mutually quite distinctly separated. Scutellum well developed, transverse, broadly im- pressed, the sides acute, prominent, slightly flexed posteriorly and corniform. Elytra two-fifths longer than wide, one-fourth wider than the prothorax and nearly two and one-half times as long as the latter ; sides subparallel and straight, tlie humeri scarcely prominent, the apex broadly rounded and sub- truncate, each elytron strongly callous in the middle at apical fourth ; striae rather fine but deep and abrupt, the intervals flat, three times as wide as the grooves, rather finely confusedly and moderately closely punctate when de- nuded. Prosternum "feebly impressed, the coxae separated by nearly one-half their width. Legs moderate ; tarsal claws short, connate for one-half their length, parallel, slightly everted toward apex and quite distinctly unequal in length. Length 4.2 mm. ; width 1.8 mm. Florida. A single female example collected in the extreme southern part of the State by Mr. Francis Kinzel, and kindly given to me by Mr. Jiilich. It is somewhat intermediate between the texana and trinotata groups of the genus, but is widely distinct from any other species. The scales are shorter broader and larger than in any other form known to me, not even excepting cylindrica, some of those on the under surface of the prosternum being only slightly longer than wide. The median parts of the third and fourth ventral seg- ments are abruptly glabrous, the normal scales being replaced toward the apex of each by very minute slender squamules sparsely dis- tributed. 566 Coleopterological Notices, IV. 4 TricllO'baris COIupacta n. sp. — Oblong, strongly convex, robust, black, densely clothed throughout with long white moderately wide recum- bent scales, which are not distinctly oblique at the sides of the elytral inter- vals, the scales not quite in mutual contact on the upper surface but very nearly so, broad, denser and conspicuous throughout the under surface, ex- cepting the usual abruptly glabrous spot at the middle of the third and fourth ventral segments. Head glabrous, minutely, sparsely punctate ; beak robust, short moderately arcuate, very densely and evenly squamose throughout, distinctly shorter than the prothorax in both sexes ; antennre stout but long, the second funicular joint longer than wide, obconical one-half longer than the third, outer joints transverse, the club robust, conoidal, pointed, as long as the four preceding joints combined, slightly pale in color, very densely clothed throughout with small robust subrecumbent squamules, which are white on the basal half, fulvous thence to the tip, the basal joint constituting about one-half the mass, the annulations not very distinct. Prothorax two- fifths wider than long, the sides feebly convergent and often broadly sinuate to apical third, then strongly rounded and subprominent, thence strongly convergent and broadly constricted to the apex ; disk with the two basal sub- denuded spots large and distinct, the scales directed transversely. Scutellum short, very transverse, broadly impressed, glabrous, corniform at the side*. Elytra rather shorter and broader than usual, scarcely more than one-fourth longer than wide, abruptly one-fourth wider than the prothorax and a little more than twice as long as the latter ; sides parallel and straight ; apex abruptly, broadly rounded ; striae simply indicated by fine partings of the vestiture. Prosternum feebly impressed, separating the coxae by one-third of their own width. Length 4.5-5.3 mm. ; width 2.0-2.6 mm. Southern California ; Arizona. Of this distinct species I have before nie a series of about fifty specimens. It may perhaps be confounded at first sight with miicorea, but is shorter and stouter, the upper surface more convex and the sides of the prothorax less acuteh" prominent. The scales are broader and denser and are not replaced by piceous squamules at the sides of the prothorax beneath, and are not oblique, or only feebly and accidentally so, at the sides of the elytral intervals. The male has a broad feeble and normally squamose impression in basal half, and the fifth segment is as long as the two preceding combined, with a small shallow emargination at the apex, from the bottom of which there projects a short dentiform lobe, analogous to that of Desmogli/ptus crenatus. 5 Triclioltaris texana Lee. — Prop. Am. Phil. Soc, XV, p. 288. Parallel, somewhat similar in outline to trinotata, but much more densely clothed with yellowish-cinereous scales, which are broader, with the basal denuded spots of the prouotum almost completely CoJeopterological Notices, IV. 567 obsolete. The beak in the male is quite distinctly shorter than the prothorax, the antennas stout, the second and third funicular joints equal and slightly wider than long, the outer joints becoming ex- tremely wide and subcontinuous in outline with the club, the latter small but thick, only slightly longer than wide, conoidal, densely pubescent, the basal joint constituting rather more than one-half the mass. Prothorax scarcely one-third wider than long, with the sides straight and parallel to apical third, then broadly rounded and convergent and somewhat constricted to the apex ; disk deeply, very densely punctate, without impunctate line. Elytra a little wider than the prothorax and about two and one-third times as long, l)arallel, abruptly and broadly rounded at apex, the sculpture and striation concealed by the vestiture, the stria; feebly indicated by fine partings of the scales, which are not oblique along the sides of the intervals. Prosternum distinctly impressed, separating the coxae by about one-third of their own width. Length 4.3-5.1 mm. ; width 1.15-2.0 mm. Texas and Colorado. The third and fourth ventral segments are denuded toward base in the middle, and, in the male, there is a large elongate flattened or very feebly impressed area in basal half, extending substantially to the base, in which the normally recum- bent scales become longer, more slender, stiff and semi-erect setae; there is also a small spot in the middle of the fifth segment in which the vestiture is similarly modified. n Triclioliaris cylindrica n. sp. — Parallel, subcylindrical, convex, vei'y narrow and elongate, black ; integuments concealed above by an exces- sively dense covering of large wide strigose scales, tVie denuded pronotal spots feebly indicated on the basal margin only, the scutellum glabrous. Head glabrous, opaque, almost impunctate, the transverse constriction very strong liut not grooved and caused, as usual, by the pronounced gibbosity at the base of the beak, the latter strongly, evenly arcuate, moderately robust, densely squamose, scarcely as long as the prothorax in the male, the antennae nearly as in texana but less stout. Prothorax one-fourth wider than long in the male, but still longer in the female, constricted near the apex, the sides broadly rounded, gradually becoming parallel and nearly straight in basal half; base transverse, broadly bisinuate; disk evenly, extremely densely punctate, without trace of median line, the surface completely concealed by the large transversely directed scales, which are in mutual contact. Scutellum moderate, transverse, broadly, deeply impressed but not so acute and promi- nent at the sides as in texana. Elytra a little wider than the prothorax and nearly two and one-half times as long, parallel, abruptly and broadly rounded at apex, the pygidium feebly oblique and visible behind, the humeri slightly 568 Coleopterological Notices, IV. prominent ; disk completely concealed by a covering of large contiguous scales, which are not even finely parted along the strife. Abdomen densely squamose, middle parts of the third and fourth segments glabrous toward base only. Prosternum not distinctly impressed, separating the small coxse by fully one-half of their own width. Length 8.5-4.7 mm. ; width 1.3-1.7 mm. Arizona. Somewhat allied to texana, but quite different in its still narrower, cylindrical form and denser vestiture, larger suboval scales which are in close contact throughout, in the smaller and more distant ante- rior coxtB and less impressed prosternum. In the male there is, at basal third of the abdomen, a small elon- gate-oval flattened area in which the scales become bristling semi- erect and acutely pointed sette. Several specimens before me are almost completely denuded, and the pronotal punctures are readily observed to be fine deep and frequently subcoalescent in a longitudinal direction, but not forming rugise like those occasionally seen in mucorea, in which species also the sculpture of this part is much coarser. Anteriorly the constric- tion which is really strong, although not very distinct when nor- mally squamose, is traceable entirely across the dorsal surface, the sculpture in the constriction consisting of strong, longitudinal and coarser rugiform ridges. RHOPTOBARIS. LeConte— Proc. Am. Phil. Soc, XV, p. 287. The single species constituting this genus has nearly all the generic characters of Orthoris, but seems to differ sufficiently in tlie form and structure of the beak, prosternum and scutellum to fully warrant its generic isolation. The beak is rather robust, moderately and evenly arcuate, differs considerably in the two sexes, and is separated from the head by an extremely broad and feeble transverse impression. Epistomal lobe short, limited at each side by a very small oblique fissure, and narrowly and deeply sinuate at the apex. Antennae somewhat slender, the club elongate-ovoidal, densely pubescent and indis- tinctly annulate, the basal joint composing about one-third of the mass. The mandibles are well developed, arcuate, decussate when closed and deeply notched at apex. The prosternum is flat, not distinctly tumid before the coxae and separates the latter by one-third of their own width. Prothorax at Coleopterological Notices, IV. SfiO base quite perceptibly narrower than the elytra. Scutellum trian- gular, flat, nearly as long as wide, deeply and densely sculptured like the surrounding surface of the elytra and not impressed. The legs are moderately long, the tarsi slender, the ungues well developed and unusually thick, as in Orthoris. The oblique pygidium of Rhoptobaris and Orthoris appears to indicate a certain affinity with the Centrini, and, although this character occurs also in the Barini proper, it would seem more natural to place these genera as near the Centrini as possible. The elongate antennal club, also, is more of a centrinide than a baride character, it being highly developed for example in Cylindrocerus. 1 Rlioptoliaris canescens Lee. — Proc. Am. Phil. Soc, XV, p. 287. Elongate-oval, black throughout and strongly convex, subopaque, the elytra less densely sculptured and a little more shining, the vestiture consisting of very short, moderately dense setae, giving a gray pruinose appearance to the surface. The beak is rather stout, distinctly arcuate, one-third longer than the prothorax in the male, but nearly one one-half longer than the latter in the female and distinctly more slender ; antennae inserted slightly beyond the mid- dle, the funicular joints small and subequal, the club elongate, fusi- form, abrupt, very densely pubescent, not distinctly annulate, a little shorter than the funicle in the male, but fully as long as the latter in the female. Prothorax in the male two-fifths wider than long with the sides strongly convergent from base to apex and evenly moderately arcuate throughout, not in the least constricted, in the female scarcely perceptibly wider than long, the sides being very feebly convergent from base to apex ; disk without impunctate line, finely and very densely punctate throughout. Elytra in both sexes abruptly and quite distinctly wider than the prothorax, and, in the male, nearly three times as long as the latter, in the female not quite two and one-half times longer, the striae deep and abrupt, not very coarse, the intervals about three times as wide as the striae, finely, confusedly and very densely punctate throughout. The male is much larger and more robust than the female, and has, at the apex of the fifth segment, a short obtusely rounded dentiform lobe. Length 3.4-4.0 mm.; width 1.3-1.6 mm. Colorado. Of the habits of this interesting species I believe nothing has been recorded. 570 Coleopterological Notices, IV. ORTHORIS. LeConte— Proc. Am. Fliil, Soc, XV, p. 286. The external appearance of the species composing this genus cer- tainly conveys but little idea of their true affinities, for, as remarked by Dr. LeConte, they quite closely resemble Orchestes. Rhopto- baris constitutes, howev'er, an excellent connective bond in every way with the more usual habitus of the tribe. There are several inaccuracies in the original diagnosis of the genus, which is drawn from the female alone. The beak is stated to be "not curved," and the prosternum "broadly though not deeply sulcate in front." The beak, even in the very long slender form occurring in the female of C7-ofchi, is feebly, though very sensibly, curved, and in the male of crotchi and female of cxjlindrifer, it becomes quite conspicuously so. The modification of the prosternum is peculiar, this part being rather narrowly and deeply impressed along the middle, but not at all abruptly sulcate ; the peculiarity consists in the fact that the canaliculation is not a depression below the general surface of the prosternum as in other genera, but is caused by a tumid elevation before each coxa, the impression being an intervening valley between the two prominences. The beak in Orthoris is slender and separated from the head by a transverse impression, which is narrower and much stronger than in Rhoptobaris; but in the structure of the prostomal lobe and mandibles the two genera are nearly similar. The antennae are of the same aberrant t3^pe as in Rhoptobaris, the club being sometimes greatly elongate, a form feebly suggested in the genus Hesperobaris. The front coxse are very narrowly but distinctly separated. Our two species may be easily recognized as follows: — Lusti'e alutaceous ; setse longer, confusedly dispersed on the elytral intervals : pronotal punctures finer and dense ; beak in the female very long and slender, the antennal club in that sex not quite as long as the funicle. 1 crotclii Lustre polished ; setae shorter, much sparser and more rigid, arranged in a single line on each interval ; pronotal punctures rather coarse and not so dense; beak in the female much shorter and more arcuate, the antennal club distinctly longer than the entire funicle 2 cylilldl'ifer 1 Orthoris crotclii LeConte— Proc. Am. Phil. Soc, XV, p. 286. Moderately short and stout, convex, black throughout and some- what dull in lustre, the seta? rather long, subrecumbent, flexible. Coleopterological Notices, IV. 511 luodevately sparse but very conspicuous, confusedly arranged on the elytral intervals. Beak differing greatly in the sexes, very slender, just visibly but evenly arcuate and three-fifths longer than the prothorax in the female, stouter, much shorter and distinctly arcuate near the Imse and apex in the male, the antennal club in the female scarcely perceptibly shorter than the entire funicle, but not much longer than the preceding six joints in the male. The prothorax is small, conical, truncate at apex and very feebly con- stricted anteriorly, the punctures scarcely more than one-fourth as wide as the scutellum and separated by barely one-half of their own widths. Elytra abruptly fully two-fifths wider than the prothorax, two and one-half times as long as the latter, one-third longer than wide ; sides parallel and straight, the apex broadly and abruptly rounded, the striae deep ; intervals three to four times as wide as the strife, finely and feebly, not very densely, confusedly and sub- asperately punctate. Fifth ventral segment longer than the pre- ceding two combined, acutely rounded in the female, a little more obtuse in the male. Anterior coxie separated by nearly one-fourth of their own width. Length 2.8-3 8 mm.; width 1.1-1. OS mm. California; Texas; Nebraska (Pine Ridge). In the extensive series before me the largest and smallest specimens are both females. 2 Ortlioris cylindrifer n. sp. — General form as in crotchi, but polished and more sparsely setose, the setffi moderately long, stiff, erect and bristling on the beak and pronotum, but recurved on the elytra, forming a nearly even single line on each interval. Head coarsely punctured, setose, the transverse impression narrow, strong and impunctate, the beak moderately densely punctate, rather slender, strongly arcuate at base and near the apex, some- what short, scarcely more than one-third longer than the prothorax in the female ; antennae long, the first funicular joint robust and as long as the next three, two to seven small, subequal, club very long, fully three times as long as wide, one-half as long as the prothorax and fully one-third longer than the entire funicle, abruptly wider than the seventh funicular joint, the sides straight and subparallel or very feebly divergent thence to apical third, then gradually pointed, indistinctly annulate, the basal joint longer than wide. Prothorax small, nearly one-half wider than long, the sides convergent from the base, feebly but distinctly arcuate, very obsoletely constricted near the l)roadly truncate apex : base with a small but distinct median lobe ; disk rather coarsely and not densely punctate, the punctures almost one-third as wide as the scutellum and very deep. Scutellum moderate, transversely sub- i][uadrate.

Length 3.0-3.3 mm. ; width 1.2-1.5 mm. Arizona. The description is drawn from the female, the only sex which 1 have seen. The extraordinary development of the antenna] club and shorter beak will at once distinguish the present species from crotchi. Two specimens. CEKTRIWUS. Schonherr — Curcul. Disjj. Meth., p. 308. Within the wide limits permitted by the short and somewhat ambiguous definition of Schonherr, I here regard as Centrinus, those species of Barini which have the pygidium concealed in both sexes, or never with more than the mere tip exposed, the femora unarmed, the mandibles elongate, prominent, not in the least decus- sate when closed, with the inner edge entirely free from notches and denticulation, and the tarsal claws free and divergent. In addition, it should be stated that the species are, with very few ex- ceptions, rhomboidal or rhomboid-oval to a greater or less degree, and are all more oi' less squamose. This definition, also, will at least not exclude those species defined as Centrinus by Pascoe (Ann. Mag. Nat. Hist., Oct. 1889, p. 322) viz: "Claws free; canal nearly obsolete or absent ; anterior coxae separated ; proster- num lower than the coxae ; elytra broader than the prothorax." With these characters are associated others, even in our own somewhat limited fauna, of considerable variety. The beak may be very slender, comparatively robust, or slender and inflated near the base, strongly and evenly or feebly and unevenly arcuate and variously compressed and flattened, the antennae inserted beyond or behind the middle and the prothorax tubulate or not. The ante- rior coxse may be narrowly or quite widely separated, the prosternum flat or variously impressed, foveate or sulcate, often very differently modified in these respects in the sexes of the same species. Finally, the secondary sexual modification of the male may be radically dif- ferent in kind, consisting either of short or long ante-coxal corneous processes of the prosternum, or of a dentiform extension of the anterior trochanters, or of a short erect tooth-like process projecting from the inner side of the basal joint of the antennal club, never, however, by a combination of any of these three modifications; in Coleopterological Notices, IV. 573 some cases, the male appears to be entirely devoid of secondary sexual characters. In fact within the limits of the genus as thus defined by mandi- bular structure, many characters which are of generic importance elsewhere, such as the degree of separation of the coxae, nature of the prosternal impression and conformation of the prothoracic apex, lose all significance of this kind and are merely useful in defining groups. In all probability some of these sexual groups are worthy of a separate designation, but with my present lack of sufficiently exact knowledge concerning the numerous tropical forms, it would l)e manifesth^ inappropriate to do more than simply indicate those which exist within our own fauna ; this has been attempted in the following table : — Male with an erect or oblique process of greater or less length before each anterior coxa ; antennal scape not attaining the eye ; tarsal claws slender, not excavated beneath. Anterior coxse narrowly separated ; body robust. Beak thick, the antenn;e inserted beyond the middle, at least in the male ; prothorax strongly tubulate at apex I Beak very slender, the antennae inserted far behind the middle in both sexes, with tlie scape very short, coming far from attaining the eyes ; much smaller species If Anterior coxse widely separated, the beak moderately slender, often more or less inflated toward base in the female, the antennae inserted at a greater or less distance behind the nuddle Hf Male with two short arcuate prosternal processes ; anterior coxae rather widely separated, the prosterimni flat, with a small subapical excavation ; man- dibles aberrant, small, widely separated, the inner edge outwardly oblique and broadly arcuate toward apex, deeply notched externally beneath ; tarsal claws aberrant, long, stout, widely divergent, excavated beneath throughout their length ; elytra with quasi-denuded transverse inter- rupted bands IV Male without trace of prosternal or antennal modification, but with the ante- rior trochanters dentate; anterior coxae moderately separated, the pro- sternum flat ; beak somewhat stout, the antennae inserted a little behind the middle, the club of peculiar structure, the two basal joints together comprising but slightly more than one-half the mass, the first often much shorter than the second \ Male entirely devoid of secondary sexual modification of the antennaj, pro- sternum or trochanters. Anterior coxae rather widely sejjarated. Prothorax subtubulate at apex ; elytral vestiture quasi-denuded in small spots ; beak slender, rather feebly arcuate, the antennae inserted behind the middle in both sexes, the scape rather long and almost attaining the eye ; tarsal claws long, normal in structure VI 574 ' Coleopterological Notices, IV. Prothorax completely non-tubulate ; elytral and pronotal vestiture dis- posed in dense sharply-defined longitudinal lines ; beak slender, exces- sively arcuate, the antennae inserted behind the middle, the scape very short and extending only two-tliirds the distance thence to the eyes... VII Anterior coxse narrowly separated. Beak slender, with the antennse inserted behind the middle, dissimilar in the sexes, shorter, almost evenly arcuate and cylindrical in the male, longer, nearly straight but abruptly bent near the base and broadly, gradually flattened toward apex in the female; prosternum not im- pressed, but with a small subdenuded point, from which the scales radiate in all directions ; scutellum very small, rounded, glabrous ; vestiture more or less uneven Till Beak rather stout and cylindrical, the antennaj inserted beyond the mid- dle, the scape extending almost to the eye IX Male without secondary sexual modification of the prosternum or trochanters, but having the outer joints of the antennal funicle obliquely truncate and often prominent internally, and tlie basal joint of the club with a large glabrous area on the inner side, at the middle of which there is a tumid or dentiform process ; pygidium with the apical portion exposed in both sexes ; anterior coxje narrowly separated, tlie prosternum generally with a deep transversely oval pit behind the apical margin ; basal impression of the beak almost obsolete ; scutellum rather large and always densely albido-pubescent X The species are numerous and are equally abundant in South America ; they are generally small and most of the large Brazilian forms will have to be assigned to other diverse genera. Those of the United States may be thus distinguished: — Subgenus I. Elytral intervals alternately more densely punctured and pubescent. Pronotal punctures rather coarse, deep, rounded, not at all coalescent ; beak in the male barely as long as the head and prothorax and very thick, especially toward base 1 puiictirostris Pronotal punctures finer, subcoalescent longitudinally ; beak in the male much smoother in apical half, more slender, less distinctly robust toward base and fully as long as the head and prothorax 2 laevirostris Elytral intervals narrower, all coarsely, sparsely and rugosely punctate ; body shorter and more broadly oval ; upper surface sprinkled with large, widely distant, white scales.

Smaller species, the prouotal punctures very dense and polygon ally crowded ; squamules of the elytra and median parts of the pronotum fine, with widely dispersed, larger and paler scales 14 perscittis Larger and much broader species, the pronotal punctures smaller, less closely crowded, the elytral squamules longer, denser, paler and without distinct widely dispersed scales 15 exillailS Subgenus IV.

Beak compressed, stronghj punctate and uhruptlij Lent near the base in the male, but cylindrical, polished, almost impunctate and more evenly arcuate in the female. Squamules borne by the strial punctures of the elytra inconspicuous. Pronotal punctures larger, distinct, close but not densely crowded. Larger species, the antennal club robust ; punctures of the elytral inter- vals coarse and rounded, distinctly defined, each deeply enclosing a small white scale 2(j denticoriiis Smaller species, less robust and more parallel, the antennal club smaller ; interstitial punctures closer and confused 27 salel)roSllS Pronotal punctures small, extremely densely crowded ; antennae rufescent, the club large and robust ; body broadly oblong 28 pingiiesceilS Squamules borne by the strial punctures l)road and distinct. 29 piilveruleiitus The identity of subgenus "X" with Odontocorynus Sch., is in- ferred from the description given by Lacordaire. We have no species in which the antennal joints four to seven are internally spinose, but several in which the two or three outer joints of the funicle are slightly prolonged and acuminate within. The Mexican Gentrinus larvatus and tonsilis of Boheman, also belong to this subgenus without doubt. 1 CeutrillUS puiictirostris Lee. — Proc. Am. Phil. Soc, XV, p. 309. Very robust, oval, convex, piceous-black, the elytra, beak, antennoe and legs more or less rufescent; vestiture consisting of large whitish scales, denser toward the sides of the pronotum and also, to some extent, on the wider of the elytral intervals, giving a subvittate appearance ; under surface densely squamose. Beak decidedly thick, moderately arcuate, about as long as the head and prothorax, rather coarsely, deeply punctured, but densely and rugulosely so only at 578 Coleopterological Notices, IV. the sides toward base; antennae inserted at the middle, the second funicular joint three-fifths as long- as the first; club abrupt, rather large, very robust, densely pubescent, with the basal joint compos- ing- fully one-half of the mass. Prothorax fully one-third wider than long, the apex tubulate and two-fifths as wide as the base; punctures rather large, deep, circular, close but not in actual con- tact, the smooth impunctate line distinct. Elytra large, quite dis- tinctly wider than the prothorax and about twice as long-, the sides just visibly convergent from the humeri to apical third, then gradu- ally and broadly rounded and strongly convergent, the apex acutely ogival; disk with moderately coarse, abrupt stride, the intervals flat, alternating wide and narrower, the wide intervals, beginning with the first, rather finely, extremely densely punctate, the narrower more coarsely and not so closely so, the punctures all distinct. Pro- sternum in the male with an oval and excessively deep pit between the corneous processes, the latter very robust, somewhat long, gradually arcuate and inclined forward from the base, obtusely acuminate at apex and not quite as long as in bjevirostris ; anterior coxffi separated by about one-third of their own width. Length 5.6 mm.; width 2.7 mm. Colorado. Cab. LeConte. This interesting species is represented by the unique male type only. 2 Centrinus laSTirostris Lee. — Proc. Am. Phil. Soc, XV, p. 309. Robust, oval, convex, piceous, the integuments moderately shin- ing, somewhat densely clothed with elongate-oval whitish scales on the pronotuni in the middle through basal half and toward the sides, but elsewhere spar-sely covered with fine and darker squamules; on the elytra the white scales are dense on the alternate intervals be- ginning with the first, least conspicuously so on the third, the other intervals more sparsely clothed with slender and darker scales ; under surface densely clothed with large white scales. Beak in the male moderately slender, smooth, only deeply and rugulosely punc- tured at the sides toward base, moderately and evenly arcuate and fully as long as the head and prothorax, the antennas inserted just behind the middle, the second funicular joint nearly three-fourths as long as the first and fully as long as the next two combined ; club small, oval, abrupt, densely pubescent, as long as the preceding- four joints and with its basal joint nearly one-half of the whole. Coleopterological Notices, IV. 579 Prothorax but slightly wider than long, tubulate at apex, the punc- tures small, deep, close, tending to coalesce longitudinally, the median polished line distinct. Elytral intervals wide and flat. Prosternum with an elongate-oval, excessively deep excavation, with its edges rounded, the coxa? sepai'ated by but slightl}' more than one-fourth of their own width, the large corneous process before each arising vertically for a short distance, then flexed abruptly and obliquely for- ward, becoming finely acuminate. Length 5.8 mm. ; width 2.8 ram. Missouri. Cab. LeConte. Represented by the unique type. The narrowly vittate elytra will readily serve to identify this distinct species. 3 Centriiitis striatirostris Lee. — Proc. Am. Phil. Soc, XV, p. 309. Robust, oval, convex, piceous and shining, the vestiture sparse, whitish, consisting of very elongate narrow scales and finer hair- like squamules indiscriminately mingled on the elytra, the finer squamulcs not noticeably darker in color; on the under surface they are broader and denser, and on the pronotum are also coarser toward apex and at base near the sides and in the middle, also in a large conspicuous spot at each side of the scutellum. The beak is rather stout and feebly arcuate, but slightly longer than the head and pro- thorax, deeply punctate and longitudinally rugose at the sides, the antennse inserted just beyond the middle, the second funicular joint less than one-half as long as the first and about one-half longer than the third, the club rather large, oval, fully as long as the preceding five joints together, densely pubescent, the basal joint two-fifths of the whole. Prothorax strongly tubulate at apex, the disk with coarse rugose sculpture and a narrow impunctate line. Elytra a little wider than the prothorax and about twice as long, the strife rather coarse, deep, the intervals flat, two to three times as wide as the grooves, coarsely and sparsely punetato-rugulose. Prosternum in the male with a large elongate-oval extremely deep excavation, extending to the coxa?, the latter separated by two-fifths of their own width in both sexes ; in the female the prosternum is flat, with a small abrupt oval and extremely deep excavation near the anterior margin. Length 4.4-4.5 mm. ; width 2.25-2.4 mm. Texas. The ante-coxal corneous process of the male is erect, short, stout, acuminate and about as long as the antennal club in the specimen which I have under observation. 580 Goleopterological Notices, IV. 4 Ceiitrinus niodestus Boh. — Sch. Cure, III, p. 772. A well-known species of robust, oval, strongly convex form and piceous color, sparsely sprinkled with coarse white scales and nar- rower brownish squamules above, and more densely covered with whitish scales beneath. The beak is about one-half as long as the body, evenly but not very strongly arcuate, moderately stout, slightly gibbous at base, so that it is separated from the head by an unusually deep and sharply marked transverse impression ; antennae normal, inserted a little beyond the middle, the scape short, extend- ing about two-thirds the distance to the eyes, the second funicular joint scarcely more than one-half as long as the first. Prothorax strongly constricted and almost tubulate at apex. Prosternum with a deep oval abruptly glabrous subapical spot, which is very deeply and transversely excavated at the bottom, and continued posteriorly by a feebly defined canaliculate and squamose impres- sion, which becomes narrower and gradually evanescent before the coxa\ the latter large and separated by scarcely more than one- fourth of their own width, with the middle of the anterior margin of the acetabula elevated in a feeble cusp-like prominence, or short corne- ous process in the male. Length 4.0-4.5 mm.; width 2.3-2.5 mm. The four specimens in my cabinet are from Pennsylvania and Florida. In well preserved specimens a small spot of dense scales is evident at each side of the scutellum, and another just before each humeral callus, the former not being as large or conspicuous, however, as in striatirostris. 5 Ceiltrinus tortuosus n. sp. — Ratlier robust, feebly rhomboid-oval, convex, shining, coarsely sculptured, piceous-black, the antennse paler ; ves- titure very sparse above, consisting of large white scales and small narrow- brown squamules indiscriminately mingled on the elytra, dense beneath, and with the scales white, short, broad and truncate. Head almost completely impunctate, the transverse constriction abrupt, almost in the form of a groove ; beak rather stout, feebly arcuate, very coarsely, deeply, longitudinally punc- tate and rugulose at the sides, a little longer than the head and prothorax in the male, the antennse inserted distinctly beyond the middle, the scape short, second funicular joint one-half as long as the first and nearly as long as the next two, club well developed, oval, abrupt, densely pubescent, about as long as the preceding five joints together and with its basal joint composing about one-half of the mass. Prothorax three-fifths wider than long, the sides dis- tinctly convergent and almost straight from the base to apical third, then broadly rounded and convergent to the deep apical constriction, the apex strongly tubulate, truncate, not quite one-half as wide as the base, the latter transverse and perfectly straight, the median lobe less than one-third of the Coleopterological Notices, IV. 581 total width, abrupt, prominent and rounded ; disk with coarse oblique parallel wavy rngse, and with a narrow subcarinate itnpunctate line in basal two- thirds. Scutellum glabrous, small, subquadrate, broadly emarginate at apex and deeply impressed along the middle. Elylra at the large and somewhat prominent humeri, conspicuously wider than the prothorax, distinctly more than twice as long as the latter, the sides rapidly convergent from base to apex and feebly arcuate, the apex narrowly rounded ; disk with moderately coarse, deep, abrupt, finely and remotely punctured strise, the intervals flat, three times as wide as the grooves, coarsely, not densely punctato-rugulose. Length 3.S mm. ; width 2.0 mm. Texas. The single specimen is a male and agrees nearly in prosternal structure with modestus, the surface being very broadly and feebly impressed, except just behind the apical margin, where there is a large and transversely oval, extremely deep excavation. The cox» are much more widely separated than in modestus, the interval being equal to fully one-half of their own width, and the form of the body is more narrowly oval ; it also differs greatly in pronotal sculpture, the latter being finer and in the form of long oblique rugfe. In the male the middle of the anterior margin of the ante- rior acetabula has a small feeble cusp-like elevation as in modestus.

Somewhat broadly oval, convex, black throughout, densely and uniformly clothed above with long more or less narrow lineate squamules, pale ochreous-yellow to whitish in color, a little paler, denser and much wider beneath. Beak similar in the two sexes, a little longer in the female, very strongly arcuate, fully one-half as long as the body; antennae inserted well behind the middle, the second funicular joint but slightly elongate, not one-half as long as the first and one-half longer than the third ; club abrupt, moderate, oval, densely pubescent, nearly as long as the four preceding together and with its basal joint composing nearly one-half of the mass. Prothorax fully one-half wider than long, conical, with the sides feebly arcuate, feebly constricted near the apex, the squamules denser and broader on the small but prominent basal lobe. Elytra a little wider than the prothorax and nearly twice as long. Pro- sternum in the male narrowly, extremely deeply excavated along 582 Coleo2')terological Notices, IV. the middle, with a long erect anteriorly bent horn before each coxa, the coxae separated by scarcely more than one-third of their width; in the female with a small but extremely deep excavation near the anterior margin, bordered on each side by a longitudinal ridge, ex- terior to which there is also a deep excavation, devoid of corneous processes and with the coxa^ separated by fully two-thirds of their own width. In the male there is a rounded very feebly impressed spot near the base of the abdomen, which is abruptly nearly gla- brous, and in which the ordinary scales become semi-erect and each deeply split into two or three hair-like processes. Length 2.1-2.7 mm.; width 1.0-l.fi mm. New York, Florida, Nebraska, Arkansas and Arizona. The sexual modifications in this small group of species are remarkable, especially in the divergence of prosternal impression, and in degree of separation of the anterior coxae. 7 Centrinus altootectlis n. sp. — Rather broadly oval, convex, black, densely and uniformly clotlied with rather wide white scales, which are but slightly broader and denser beneath. Head and base of the beak squamose, the beak strongly, evenly arcuate and slender in both sexes, but scarcely longer than the head and prothorax in the male, and fully one-half as long as the body in the female; antennfs in the male with the basal joint of tlie fnnicle as long as the next three, the second small, but slightly longer than the third, three to five each a little longer than wide, the club small abrupt, short, oval, scarcely longer than the preceding three joints together ; in the female the club is less abrupt, larger and more elongate, with the basal joint of the funicle barely longer than the next three. Prothorax fully one-half wider than long, the sides distinctly convergent from the base and broadly arcuate, rather strongly constricted behind the apex, the latter sometimes almost tubu- late; base transverse and straight, the median lobe small but very prominent; disk uniformly and very densely punctate and squamose. Scutellum very small, almost concealed by the vestiture. Elfjtra hemi-elliptical, a little wider than the prothorax and twice as long in the male, but relatively dis- tinctly shorter in the female ; humeri moderately prominent ; strife rather fine, very deep, the intervals flat, three or four times as wide as the strife, densely punctato-rugulose. Prosternum in the male with an elongate-oval, extremely deep excavation, the coxse separated by one-half of their own width ; in the female, with a small rounded very deep pit just behind the apical margin, also somewhat impressed laterally as in jiirumnus, and with the coxpe separated by two-thirds of their own width. Length 1.75-2.5 mm. ; width 0.7-1.3 mm. Florida, Texas (Columbus). In the male there is a long very slender finely acuminate horn before each coxa, the process being inclined forward and very feebly Coleopterological Notices, IV. 583 arcuate ; in the same sex there is a small semi-glabrous flattened spot near the base of the abdomen, in which the ordinary scales become very sparse small and narrow, but recumbent and not modified in structure. This species may be readily distinguished from picumnus by its broader white scales, shorter beak with more pronounced sexual differences, by its smaller size and more slender form. Twelve specimens. III. 8 Centriniis neglectlis Lee. — Proc. Am. Phil. Soc, XV, p. 310. Similar in form and structural characters to perscillus, but clothed densely throughout with ochreous-yellow scales, broad beneath, narrow and slender above, where they are unevenly mixed with darker brown scales of the same kind, the brown scales forming also two distant subapical spots. Beak slender, very strongly arcuate, not quite one-half as long as the body in the female, the antennae inserted a little behind the middle, the scape rather abruptly clavate, extending barely three-fourths of the distance to the eyes; second funicular joint slender but short, scarcely one-half as long as the first and a little longer than the third, the outer joints larger, the club as in perscillus Prosternum flat, abruptly declivous ante- riorly to the transverse constriction, the coxte moderate, remote, separated by distinctly more than their own width. Length 3.6-4.0 mm.; width 1.7-1.8 mm. Texas, Louisiana and Kansas. The specimens before me are females, but the male is said to have a short corneous process before each coxa. The statement in the original description that the second funicular joint is "nearly as long as the first," is a con- spicuous error. This species is closely allied to perscillus. 9 CeiltrinilS grisesceus n. sp. — Feebly rhomboideo-elliptical, convex, rather dull, black throughout, densely clothed throughout beneath with large wide yellowish-white scales, and, on the upper surface, with squamules which are narrower, and luteous-white and dark brown intermingled, the latter more evident in two distant spots near the apex as in neglectus. Beak strongly arcuate, relatively not longer and but slightly more slender in the female than in the male, but notably more arcuate in the former sex, not quite one- half as long as the body; antennse inserted as in neglectus, the second funicular joint much more slender than the first and not quite one-half as long, much .shorter than the next two together ; club about as long as the preceding four joints combined, not very abrupt, densely pubescent, with the basal joint composing but slightly less than one-half of the mass. Prothorax one-third 584 ColeopteroJogical Notices, I V. wider than long, the sides feehly convergent and nearly straight in hasal two- thirds, then broadly rounded and gradually convergent to the apex, which is truncate and one-half as wide as the base, the latter straight and transverse, with the median lobe small but abrupt and prominent, rounded ; apical con- striction broad and feeble ; disk somewhat coarsely deeply and very densely punctate, with a narrow, more or less incomplete impunctate line. Scutellnm moderate in size, quadrate. Elytra slightly wider than the prothorax and twice as long, the humeri rather prominent, the sides thence strongly conver- gent and very feebly arcuate to the narrowly rounded apex ; striae fine but deep, the intervals flat, three or four times as wide as the striae, confusedly, rather coarsely punotato-rugulose. Prosternum broadly, distinctly impressed in the middle in both sexes, but much more deeply so in the male the latter having a short erect acuminate horn before each coxa ; anterior coxae rather large, separated by barely their own width. Length 3.5-4.1 mm.; width 1.65-1.9 mm. North Carolina (Ashevillo) ; Ohio; Illinois; Missouri. Very closely allied to neglectus, but differing in its whitish and not dark yellow vestiture, by the broad distinct impression of tiie prosternum in both sexes, and quite distinctly less widely separated anterior coxfe. Numerous specimens. 10 Centriiius perscilliis GylL— Sch. Cure, III, p. 762. Elliptical, moderately robust, the upper surface feebly flattened, black, densel}" clothed throughout above and beneath with grayish- white elongate scales. Beak slender, very strongly, evenly arcuate, one-half as long as the body, with a narrow smooth impunctate line ; sides toward base densely punctate ; antennae inserted a little behind the middle, the scape extending thence three-fourths of the distance to the eyes, second funicular joint slender but unusually short, not quite one-half as long as the first and but very slightly longer than the third; club moderate, oval, densely pubescent, a little longer than the preceding four joints together, and with the basal joint constituting somewhat less than one-half the mass. Pro- sternum flat, rather abruptly declivous anteriorly to the transverse constriction, separating the coxte by quite distinctly more than their own width. Length 3.7 mm.; width 1.85 mm. The two specimens before me are apparently females, and are from Kansas and Minnesota. I think that this is without doubt the species described by Gyllenhal, and the species so identified by LeConte (Proc. Am. Phil. Soc, XV, p. 310), having the second funicular joint as long as the first and the prosternum deeph' exca- vated, is probably some other species which remains unknown to me. Coleopterological Notices, IV. 585 The species described hy Gyllenhal is said to be covered densely with narrow scales, agreeing* with the present form, but in jjerscillus Lee. the scales are especially noted as being "not linear but oval." 11 Centriniis finitimiis n. sp. — Ehomboid-oval, convex, slightly shining, black, the tibiie feebly rufescent ; vestiture yellowish, pale, consist- ing, on the upper surface, of long, slender but rather large squaniules, which are rather dense and uniformly distributed, and, beneath, of larger and very dense scales. Head dull but smooth, minutely, sparsely punctate, the impi'es- sion almost obsolete, with a small median fovea ; beak long, polished, slender, evenly, rather strongly arcuate and fully one-half as long as the body, but veiy feebly thickened toward base, strongly flattened toward apex, where it is distinctly dilated, scarcely noticeably enlarged at the point of antennal insertion , rather coarsely, rugosely and densely punctate, the punctures forming series and grooves ; antennse inserted at the middle, black, somewhat slender, and with the basal joint of the funicle barely as long as the second, the latter as long as the next two combined. P)-othorax about three-fifths wider than long, the sides broadly, evenly and strongly arcuate, becoming parallel toward base and broadlj'^ sinuate near the apex, the latter much less than one-half as wide as the base ; disk coarsely, deeply, very densely punctate, the punctures tending to coalesce longitudinally ; impunctate line narrow but almost entire. Scutellum small, quadrate, enlarged and broadly emarginate at apex, impressed along the middle, setose at the sides.

Length 2.9-3.3 mm.; width 1.4-1.7 ram. Texas (Dallas) — Mr. Wickham ; Missouri. This species differs from perscillus in its smaller size, broader form, more transverse prothorax, structure and vestiture of the scutellum, and generally silaceous squamules of the upper surface. Seven specimens. 12 Centrinus liospes n. sp. — Rhomboidal, convex, black, the antennse piceous, the club pale ; vestiture white, consisting of long, slender, rather dense and uniformly distributed squamules on the upper surface, and large, broad, very dense scales beneath.

Length 3.5 mm. ; width 1.7 mm. Arizona (Tugson). Mr. Wickham. I have only seen the female, and the remarkable form of the beak, reminding us strongly of Eunyssobia (Euehaetes Lee), is probably peculiar to that sex, as it may be observed to a less degree in several other species of this subgenus, and notably grisescens ; at any rate, the peculiar basal enlargement is much more developed in the female than in the male of that species. 13 CentrinilS claresceilS n. sp. — Rather narrowly ovoidal, convex, pale rufo-testaceous throughout, the scutellum, head and beak rather darker and piceous ; vestiture consisting of rather large, moderately elongate, ochre- ous-yellow scales, rather dense and uniformly distributed above, very dense and broader beneath.

Length 2.9 mm. ; widtli 1.35 mm. District of Coluiabia. The typical representative above described is a male. The species is altogether distinct from any other here noted, and may be known at once by the pale coloration of the integuments and the ochreous scales. 14 Ceiitriiilis perscifus Herbst — Kiifer, VII, p. 28 (Curculio). Oval, convex, piceous-brown, the elytra rufous; vestiture not very dense, ochreous-yellow, consisting of closer and broader scales beneath, and on the upper surface of narrow squamules which are al)i-upt]y much denser along the sides of the pronotum, the elytra also with a few larger whiter and very widely dispersed scales.

Elytra conoidal, narrowly rounded at apex, a little wider than the pro- thorax and sensibly more than twice as long, the striaB fine but deej), the intervals densely, confusedly punctato-rugulose, flat, three to four times as wide as the grooves. Prosternum in the male narrowly, Annals N. Y. Acad. Sci., VI, Oct. 1892.— 39 588 Coleopterological Notice's, IV. deeply excavated and having a very stout acuminate erect process before each coxa ; in the female flat, without trace of impression; anterior coxae separated by three-fourths of their own width. Length 2.5-2.7 mm. ; width 1.3 mm. The two specimens before me are from New Jersey and Indiana. It is somewhat singular that Dr. LeConte should have failed to see the corneous prosternal processes in the male of this species; they are quite conspicuous and must have been concealed by the anterior femora in the specimens which he examined. 15 CeiltrillUS exulans n. sp. — Rather broadly rhomboid-oval, convex, piceo-rufous throiighoiit and densely clothed with scales, wliich are narrower and yellowish in the middle three-fifths of the pronotnm, winter and denser at the sides and also on the elytra near and especially behind the sciitellum.

Scutellnm moderate, squamose, slightly trans- verse. Elytra slightly wider than the prothorax and fully twice as long, the outline almost evenly ogival from base to apex, the latter acutely rounded ; humeral callus quite distinctly prominent; disk rather finely, deeply striate, the intervals wide, fiat, densely and confusedly punctate. Abdomen very densely punctured and squamose throughout. Prosternura nearly flat, sepa- rating the coxse by appreciably less than their own width. Length 3.3 mm. ; width 1.6 mm. New Mexico (Gallup). Mr. Wickham. The single specimen is a female, but the species is very distinct and allied only to perscitus. It differs from p)erHcitus in its much larger size and stouter form, in the decidedly shorter relative length of the intermediate and posterior tibia^., and in the pronotal punc- tures which are here very close but circular in outline and not in actual contact, while in perscitus they are coarser and polygonally crowded. These two species belong to a peculiar type, distinguished from the other allies of perscillus by the very much shorter, stouter and evenly cylindrical beak. Coleoplerological Notices, I V. 589 IV.

Narrowly rhom))oid-oval, convex, black, the tibi:* and antennae rufo-piceous ; vestiture white, consisting- of long, very slender, not very densely but uniformly distributed squamules on the upper surface, which are replaced, however, by black squamules in two broad transverse elytral bands, interrupted at the suture, one at the middle and the other near the apex ; on the under surface the scales are elongate, but broader and denser. Head alutaceous, finely but strongly, sparsely punctured, glabrous, with the exception of a line of very minute squamules along the edge of the eyes; impression very broad and almost obsolete, with a small feeble median fovea; lieak abruptly polished, slender, feebly but almost evenly arcuate, gradually slightly thicker aTid more arcuate at the base, sparsely punctured and squamulose at the sides near the base but elsewhere very minutely, sparsely punctate and glabrous, not at all dilated at the antennae but gradually wider and flatter toward apex, about two-thirds as long as the body; antennge inserted just beyond basal third, slender, the scape extending almost to the eye, the first funic- ular joint slender, clavate, as long as the next two, second slender and as long as the third and fourth, outer joints slightly thicker and nearly as wide as long, club rather small and narrow, oval, pointed. Prothorax barely one-third wider than long, the sides evenly, broadly arcuate, convergent anteriorly, becoming broadly sinuate behind the apex and almost parallel near the base, the latter transverse, the lobe less than one-third the width but strongly rounded and very promi- nent; apex truncate and distinctly more than one-half as wide as the base ; disk dull, not very coarsely, extremely closely and poly- gonally punctate, the impunctate line not distinct.

Length 3.5 mm. ; width l.()5 mm. Arizona (Santa Rita Mts.). Mr. Wickham. The single repre- sentative before me is a female ; I have not seen the male. The remarkable form of the mandibles and the robust excavated tarsal claws, may ultimately necessitate the generic separation of this species, for which Mr. Pascoe has already suggested a name. The spots of the elytra appear to be denuded, but, as in all similar cases in this genus, these areas are not really denuded but quite as densely clothed with blackish and sometimes more slender squam- ules. Y. 17 CentrinilS acuniinatlis n. sp. — Narrowly rliomboidal, black, the anteinipe rufo-piceous with th« club paler and brown ; lustre dull, the sculpture dense but not very deep; vestiture pure white, consisting of broad, extremely dense scales beneath and of longer, sparser, evenly distributed squamules above, not entirely concealing the surface ; those of the pronotuui directed transversely, those of the elytral intervals not arranged in lines. Head finely, sparsely punctate, with a squamose area above each eye, the transverse impression well marked ; beak in the male distinctly robust toward base, strongly tapering thence to the apex and scarcely longer than the head and prothorax, in the female distinctly longer and much more slender, strongly arcuate, densely, deeply sculptured, squamose, the antennse inserted just behind the middle, the scape moderate, rather abruptly clavate, the funicle very long, slender, bristling with an irregular fringe of long flexible white setse along its internal side, the second joint very slender, scarcely more than one-half as long as the first and barely one-half longer than the third, two to four decreasing in length, outer joints not at all transverse, the club aberrant, slender, more than twice as long as wide, about as long as the preceding four joints combined, abrupt, densely pubescent, with the annulations very dis- tinct, almost articulate, and with the two basal joints together occupying scarcely more than one-half of the length. P)-othorax one-half wider than long, the sides broadly, feebly arcuate, gradually convergent and sinuate anteriorly, becoming neai'ly parallel toward base; apex distinctly less than one-half as wide as the base, the latter transverse, with the median lobe small but distinct; disk rather coarsely but not very deeply punctate, without median line, the punctures extremely densely, polygonally crowded, forming almost even hexagons at some points. Scutellum moderate, very densely squamose, siibquadrate. Elytra about one third longer than wide, nearly twice as long as the prothorax, and at base, rather abruptly, distinctly wider than the latter, the humeri small but prominent, the sides rapidly convergent thence to the apex and feebly arcuate, the apex very narrowly rounded ; disk deeply but not coarsely striate, the intervals three or four times as wide as Goleopterological Notices, IV. 591 the grooves, broadly convex, coarsely densely and deeply pnnctato-rugiilose. Prosternum very obsoletely impressed along the middle, separating the coxae by a little more than one-third of their own width and rather narrowly emar- ginate behind. Length 3.2-3.8 mm. ; width 1.6-1.75 mm. Texas; Arizona (Tucson). In form and size this very distinct species is nearly similar to penicellus, but the beak is shorter and the antennae of singular structure. The male difiFers from the female in having the anterior trochanters obtusely toothed. The hind til)ia3 are bent outward slightly and feebly dilated at apex, the internal spur not visible and the apical margin transversely truncate, a peculiarity of structure which is very highl}'' developed in Eisonyx. Three specimens. 18 Centrinus globifer n. sp. — Form, color, sculpture and vestiture throughont almost exactly as in acuminatus, the lustre a little more shining and the rugose punctures of the elytral intervals not quite so dense. Beak in the male thick toward base, arcuate, not quite as long as the head and prothorax, the scape short, gradually clavate, inserted at basal two-fifths, the funicle robust, cylindrical, bristling with long flexible setse, especially along the anterior or internal side, the second joint but slightly more than twice as long as wide, three-fifths as long as the fii'st and distinctly longer than the third, two to four decreasing in length, five to seveu subquadrate, monili- form, the seventh a little wider than long, the club (-"xtremely abrupt, robust, elliptical, as long as the preceding four joints together, scarcely one-half longer than wide, the sutures fine but deep, the basal joint narrower and shorter than the second, the first two together composing only one-half of the mass, the surface throughout polished and very sparsely pubescent, the first in great part, and the second near the base, completely glabrous. The prosternum is flat, with two deep approximate denuded subapical fovea), and separates the coxae by one-half of their own width. Length 3.7 mm. ; width 1.8 mm. Texas (El Paso). The extreme resemblance which this species bears to acuminatus in every external feature is very remarkable, in view of the equally striking difference in antennal structure, and in the more widely separated anterior coxte. The single male before me has the ante- rior trochanters obtusel}' dentate, the tooth lamelliform. The poste- rior tibice are nearly as in acuminalits, although a little shorter, the ])Osterior femora are also a little shorter thicker and with more arcuate external outline. vr. 19 Ceiltrinus penicellllS Ilerbst — Kafer, VII, p. 29 (Curculio^; hnJosej-iceus Gyll. : Sch.

This species is so well known, and so easily recognizable by the characters given in the table, that but little further need be said of it. The antenna? are slender, rather long, the second funicular joint very slender, fully two-thirds as long as the first and scarcely as long as the next two together, the latter equal and each distinctly elongate, the club small, rather abrupt, elongate-oval, pointed and I)ut slightly longer than the three preceding joints combined, densely pubescent and with its basal joint constituting scarcely two-fifths of the mass ; the scape is slender, rather abruptly clavate and inserted just beyond basal third. The prosternum is flat, extremely densely squamose, feebly bitumorose at the apex, and with a transverse ex- cavated groove at a sensible distance behind the apical margin, the coxa?- rather large, somewhat prominent and separated by barel}^ two-thirds of their own width. Anterior trochanters small and simple in both sexes. Length 3.5-3.8 mm.; width 1.7-1.9 mm. The series before me is from Iowa and Indiana. I have seen no specimen in which the apical subsutural denuded spots were com- pletely wanting, but the others are frequently obliterated. It is probable that the Cuban fomentosus Klug, i. litt., is a different species from this. YII. 20 Ceiltriniis liiieelllis Lee. — Proc. Ac. Nat. Scl., Phila., 1859, p. 79. A finely ornamented small species of rather robust, oval, convex form, black throughout, the antennal scape rufous; under surface clothed densely with large yellowish-white scales, the same forming three distinctly limited broad vittae on the pronotum, and covering the second elytral interval throughout, the third in apical two-thirds, the fourth in basal fourth, the sixth more or less throughout, and the seventh and eighth except toward the humeri ; remainder of the upper surface clothed with large piceous-black scales. Beak in the female slender, evenly and extremely arcuate, a little more than one-half as long as the body, the antennse inserted just behind the middle, the scape short, extending thence only two-thirds the dis- tance to the eyes, the second funicular joint slender, a little more than one-half as long as the first and distinctly shorter than the next two, the latter subequal and each a little longer than wide, outer joints gradually and distinctly transverse, the club small, narrowly oval, not very abrupt, densely pubescent, as long as the preceding four joints combined, and with the basal joint composing Coleopterological Notices, IV. 593 nearly one-half the mas^s.

Rather narrowly rhomboid-oval, convex, shining, black, the legs and antennae paler, rather sparsely clothed above with long slender white hair-like squamnles, which are uniform in size and distribution on the elytra, except a little wider just behind the scutellum, very sparse and slender on the pronotum, becoming a little broader toward base in the middle and at lateral fourth, broad and rather dense on the under surface. Beak in the male slender, strongly arcuate, nearly one-half as long as the body, the antenme inserted well behind the middle, the first funicular joint about as long as the next three, the second more slender, rather more than one-half as long as the first and about equal to the next two, the club small, robust, abrupt, but slightly longer than wide, pale, densely pubescent, with the basal joint constituting distinctly less than one-half the mass. Prothorax rather short, truncate, conical, the sides broadly rounded, the constriction feeble ; disk rather coarsely but not very deeply, moderately closely punctate, with a distinct impunctate line. Elytra a little longer than wide, slightly wider than the prothorax and not quite twice as long, conical, nar- rowly rounded at apex ; disk with deep striae, the intervals nearly three times as wide as the grooves, confusedly but not very densely punctato-rugulose. Prosternum flat, not impressed and without trace of apical constriction, but with a small denuded spot at some distance behind the apex, from which the scales radiate in all direc- tions ; coxae separated by one-half their own width. Length 2.15-3.0 mm.; width L3-L5 mm. Texas. In the female the beak is more abruptly bent near the base. The prosternum in both sexes is perfectly simple before the coxae, and without trace of the " slender cusp" mentioned by LeConte, 594 Coleopterological Notices, IV. 22 Ceiltriims imtoecilla ii. sp. — Oval, rather robust, moderately convex, black and shining throughout, the anterior tibije rufous and longer than the others ; vestiture white, rather sparse, consisting on the upper sur- face of very slender hair-like squaraules, disposed in nearly even approximate lines on the elytra, and becoming coarse and denser scales about the scutellum and in a subsutural area on each just behind the middle ; on the pronotum they are coarser and denser near the base before the scutellum and at lateral fourth ; on the under surface they become moderately wide and close, except on the apical half of the prosternum, where they are very fine and sparse but radiating from the peculiar antero-central point mentioned in the other species of this subgenus. Head i^romiuently convex, finely, sparsely punctate, the beak strongly arcuate in basal third, thence feebly arcuate and very thin viewed laterally, but broad and flattened viewed anteriorly to the apex, punctured at the sides toward base, nearly one-half as long as the body, the antennae inserted well behind the middle, nearly as in capiilalus, the first funicular joint as long as the next three, the second a little more than one- half as long as the first and about as long as the next two. Prothorax two- thirds wider than long, the apex truncate, not quite one-half as wide as the base; sides evenly, feebly arcuate and convergent from the base, the constric- tion broad and feeble ; base transverse and straight, the median lobe small but prominent ; disk rather coarsely, strongly, evenly and closely punctate, without evident inipunctate line. Scutellum small, quadrate, impressed Innately behind. Elytra a little wider than the prothorax and not quite twice as long, evenly conoideo- elliptical in outline, the humeri basal, moder- ately prominent ; disk not coarsely but very deeply, abruptly striate, the intervals flat, fully tliree times as wide as the grooves, rather finely but strongly, not densely and subtransversely punctato-rugulose. Prosternum feebly, transversely and indefinitely imjiressed anteriorly, separating the coxfe by one-half of their own width, without trace of corneous processes. Posterior tibiae slender, strongly sinuate externally at apical fourth. Length 3.'2 mm. ; width 1.65 mm. Texas. From analogy in the case of capiUatus, if we regard as the female the form having the beak more abruptly bent near the base and more widely flattened, the unique type of nubecula is of that sex, for the beak is even more noticeably flattened than in the species referred to. In the male, the beak is but slightly shorter, and is much more evenly and, on the whole, more strongh' arcuate than in the female, and is C3iindrical, although feebly flattened very near the apex. For the reasons stated, the male beak appears thicker from a lateral point of view than that of the female, but from an anterior point it is a little thinner. 23 Centrinus Clientullis n. sp. — Rather narrowly rhomboid-oval, convex, polished, black throughout, except the legs which are bright rufous ; Coleop(e7'ological Notices, IV. 595 vcstiture consisting of yellowish-white scales, broad and dense beneath, but sparse and generally slender toward the sides of the prothorax ; on the upper surface they are rather broadly oval on the elytra behind the middle and near the scutellum, but elsewhere slightly narrower ; on the pronotum narrow toward the sides and before the scutellum, but elsewhere very sparse, finer and hairlike. Head dull, very minutely, sparsely punctured, the beak in the female about one-half as long as the body, strongly and abruptly arcuate at the base, perceptibly flattened toward apex, deeply punctate at the sides toward base, the antennse inserted well behind the middle, the basal joint of the funicle elongate, nearly as long as the next four together, second rather slender, not one-half as long as the first, not quite as long as the next two, the club small and especially very short, not more than one-third longer than wide and biit slightly longer than the preceding three joints together, very abrupt, densely pubescent, with the basal joint constituting not quite one- half the mass. Prothorax rather short, two-thirds wider than long, the sides convergent and broadly arcuate from the base to the distinctly constricted apex, the latter almost tubulate and fully one-half as wide as the base, the latter straight and transverse, the median lobe small and prominent ; disk rather coai'sely punctate, the punctures shallow, close but not contiguous, with a narrow, more or less distinctly defined impunctate line. Scutellum truncate, not as long as wide. Elytra a little more than twice as long as the prothorax, and, at the small, rather prominent humeri, perceptibly wider than the latter ; sides thence strongly convergent to the narrowly rounded apex and feebly arcuate ; disk rather finely but deeply striate, the intervals between two and three times as wide as the grooves, flat, not very coarsely, moderately closely, strongly punctato rug?ilose. Prosternum broadly, scarcely visibly impressed, the anterior coxje separated by about one-half of their own width. Length 2.6-3.0 ram. ; width 1.2-1.5 mm. Texas (Columbus). Mr. Schwarz. This species is allied to capillatus, but differs in the much broader and more uneven scales of the elytra, and in its very pale bright rufous legs. IX. 24 Centriniis falsiis Lee— Proc Am. Phil.

Prothorax much wider than long-, with the sides almost parallel and feebly arcuate in basal two- thirds, tlien strongly rounded, the apical constriction extremelv feeble, the punctures fine and very dense, tending to longitudinal coalescence ; median impunctate line distinct. Scutellum xi^ry densely squaniose. Elytra a little wider than the prothorax and more than twice as long, rather less strongly narrowed to the apex than usual, the striee somewhat line but deep. Prosternum with a transverse subapical constriction, and a rather narrow moderately deep parallel sulcus along the middle, the sides of the sulcus some- what al>ruptly defined ; anterior coxie separated by scarcely more than one-fourth of their own width. Length 3.G-4.0 mm.; width 1.6-1.8 mm. Alabama and Iowa. In some respects this species forms a satis- factory ]iassage from the species with armed male prosternum, to those of the sculeUum-aJhum group. I have been unable to note any prominent secondary sexual modification of the male, X. 25 Centriniis scutelliini-alliiiin Say — Cure, p. 21, Ed. Lee, I, p, 287 {BarUlius scut. Germ. : Sell. Cure., Ill, p. 730). Subrhomboidal, convex, rather robust, the vestiture consisting of small, more or less narrow sparse w^hite scales, which become large broad and den.'^e on the under surface. Beak nearly straight, a little more than one-half as long as the body, abruptly and strongly bent at base, the flanks flattened and deeply longitudinally punctato- rugulose throughout, more strongly arcuate along the under outline behind the antennas, the latter inserted near apical third in the male, the basal joint of the funicle moderate in length, the second rather long, fully three-fourths as long as the first and subequal to the next three, joints three to seven small ; club large, elongate, oval, densely pubescent, fully two-thirds as long as the funicle, the sutures feeble, arcuate on the inner side, the basal joint constituting a little more than one-third of the whole, nearly as long as wide, with a large tumid glabrous and polished area on the inner side, at the middle of which there is an erect acute spiniform process. Protho- rax wider than long, scarcely at all constricted, the punctures rather coarse, deep, rounded, almost in mutual contact. Elytra distinctly Coleopterological Notices, IV. 5 97 wider and about three-fourths longer than the prothorax, coarsely, deeply striate, the intervals very coarsely, confusedly punctate. Prosternum scarcely impressed, but with a large transverse abru])t and very deep excavation just behind the apex, the coxfe separated by scarcely one-third of their own width. Length 3.2-4.5 mm.; width 1.7-2.3 mm. The description above given is taken from the male and in this sex the pygidium is considerably exposed between the elytral apices, and very oblique ; in the female it appears to be somewhat less ex- posed. The body is more broadly rhomboidal than in the salebrosus group, and the sexual differences in the structure of the beak are not at all evident. The male is black, but the female is almost in- variably more or less rufescent and has the prothorax shorter, the pronotal punctures larger and sparser, and the antennal club simple. This species is represented in my cabinet from New York, Indiana, Missouri and Florida ; it also occurs in Brazil. 26 CeiltrinilS denticorilis n. sp. — Robust, oblong-subrhomhoidal, convex, moderately shining, black throughout, the vestiture of the pronotum consisting of very small sparse and slender squamules, evenly distributed but denser toward the sides behind the apical margin, also along the base near the sides and on the median lobe ; on the elytra the scales are generally small, moderately wide, evenly and sparsely distributed over the intervals, each lying entirely within a very deep rounded puncture ; scales of the under surface large, broad and very dense, the color whitish throughout.

The beak in the male is feebly arcuate and much more strongly so toward base ; in the female it is scarcely at all longer but more slender, cylindrical, smooth and minutely, sparsely punctured, ex- cept just before the eyes, where the punctures become coarse and close, but not rugose, the antennae inserted just beyond the middle ; in the female the antennae are more slender and with a smaller sim- ple club. This is probably our largest centrinide. 27 CeiltrinUS saletorosus n. sp. — Oblong-oval, the upper surface moderately convex, black and dull, the legs and antennse more or less pice- ous ; vestiture whitish, consisting of large broad and very dense scales beneath, finer but extremely variable on the upper surface.

Coleopterological Notices, IV. 59!) New York; Indiana; Kentucky; Dakota; Colorado; Texas. The description is drawn from the male ; in the female the beak is quite distinctly longer and rather more slender, evenly, some- what strongly arcuate throughout, cylindrical, smooth, shining and minutely, sparsely punctate except at base, the antenna? inserted distinctly beyond the middle, and with the club unmodified. This species is the most protean in its variations of any baride which I have seen ; more especially in the vestiture of the upper surface, which may consist of ver}^ slender sjjarse squa mules, or robust oval dense and very conspicuous scales, with every inter- grade between these limits. The series before me consists of nearly sixty specimens. 28 C'entriniis pingliesceiis n. sp. — Oblong-oval, stout, moderately convex, dull black, tlie aiiteinife and the tibife at least toward apex, ruf'escent; vestiture on the upper surface consisting of yellowish scales, elongate-oval and dense on the elytral intervals, minute, slender and inconspicuous on the pronotum, hut larger and denser at l)ase near the sides and toward the middle and also in the subapical constriction, large, yellowish-white and very dense beneath Head somewhat finely, deeply, rather densely and conspicuously punctured, the impression broad and very feeble, with an elongate median fovea; beak in the male rather stout, deeply, coarsely and rugosely punctate, nearly evenly, distinctly arcuate and somewhat abruptly very stiongly so near the base, a little longer than the head and prothorax ; antennje inserted well beyond the middle, the basal joint of the funicle rather short, stout, the second fully three-fourths as long as the first and equal to the next two together, sixth and seventh internally prominent, club very robust and abrupt, as long as the five preceding joints combined, extremely densely clothed with short recumbent setiform squamules, the basal joint constituting one-third of the mass, with a glabrous internal area, not extending much beyond the middle, at the centre of which there is a very minute but acute and prominent spicule. Prothorax two-thirds wider than long, the sides broadly, evenly rounded in apical half, becoming parallel and straight thence to the base, the subapical constriction feeble but distinct ; apex distinctly less than one-half as wide as the base ; disk very finely, extremely densely punc- tured and dull, with barely a trace of a very narrow partial impunctate line.

Arkansas (Little Rock). Mr. Wickham. This species belonai'is porosa Lee. — Proc. Am. Phil. Soc, XV, p. 302. Robust, convex, polished, black, the beak, legs and antennae more or less rufo-piceous ; vestiture very sparse, consisting of minute scarcely distinguishable setaj on the prothorax, and longer poste- riorly recumbent and robust setae on the elytra, where they are piceous in color and inconspicuous, very small but whitish on tl)e under surface.

The allusion in the original description to whitish hairs on the elytra is inexact. JMICROCHOLIJS. LeConte— Proc. Am. Phil. Soc, XV, p. 303. This isolated genus is characterized by a broad, moderately con- vex body, with normally striate elytra, an unimpressed prosternum, non-tubulate prothorax and small tarsal claws, and differs greatly from Oomorphidius, under which name I have separated two of the species assigned to it by its author, in several important charac- ters as given in the table. The mandibles are rather long, prominent, feebly arcuate in ex- ternal outline, scarceh^ at all or feebly decussate when closed, and much more angulate anteriorly in this state than in Oomorphidius and Eisonyx. In fact in this and several other ways, Microcholus forms a tolerably satisfactory intermediate between the genera men- tioned and Centrinus. The two species at present known should be separated subgene- rically as follows : — Subgenus I. Beak compressed toward base, minutely, feebly punctate even at the sides, the apex flattened and siibdilated ; scutellum rather large, elongate-oval and tumid ; elytral strife much coarser, impunctate ; tarsal claws very stout; integuments nearly glabrous above 1 striatllS Subgenus II. Beak cylindrical, neither compressed toward base nor flattened at apex ; scutellum very minute, triangular ; elytral strise fine, remotely punc- tate; tarsal claws very small but slender; integuments rather densely but unevenly squamose 2 ptiiicticolli^ In general outline of the body M. puncticoUis almost perfectly resembles Simocopis amhrina Pasc. ; the beak is however quite different. I. 1 Hicrocliolus StriatllS Lee. — Proc. Am. Phil. Soc, XV, p. 304. Broadly oblong-oval, moderatel}^ convex, black, the legs rufo- piceous ; pronotum polished, the elytra slightly alutaceous; integu- ments almost glabrous above, with a cluster of large w'hite scales Coleopterological Notices, IV. GOt at the base of the pronotum at each side and a few before the scu- tellum, also several widely dispersed on the elytra and a small group at the base of the third interval ; under surface sparsely, the legs, meso- and met-episterna and sides of the last three ventral segments more or less densely, clothed with large white scales. Head separated from the beak by a very feeble impression, the beak fully as long as the prothorax, flattened near the apex and strongly compressed toward base, strongly, evenly arcuate, sparsely, very minutely punctate throughout and moderately stout; antennse slender, the basal joint of the funicle slender, fully as long as the next four, the second slender and as long as the next two, club small, stout, densely pubescent, with the basal joint constituting rather more than one-half the mass as in Oomorphidius. Pro- thorax scarcely two-fifths wider than long, the sides broadly arc- uate and gradually strongly convergent from the obtusely rounded basal angles to the apex, the latter not tubulate, the constriction very feeble ; base transverse, the median lobe wide but very feeble ; disk finely, sparsely punctate. Scutellum well-developed, elongate- oval and tumid. Elytra not at all wider than the prothorax, two- thirds longer than the latter and about as long as wide, the striae rather fine but deep, with the edges obtuse, the intervals wide, each with a single somewhat uneven series of fine distant punctures. Anterior coxte separated by rather less than one-third of their width, the tarsal claws small, short, very thick but free and mode- rately divergent. Length 4.5 mm. ; width 2.3 mm. Florida (Lake Harney). Cab. LeConte. Represented, as far as known, by the unique type. The upper surface in the type is not denuded of scales as supposed by LeConte ; the punctures, other than those very remote ones which bear the long isolated scales, bear each an infinitesimal seta. II. 2 microcliollis puncticollis Lee. — Proc. Am. Phil. Soc, XV, p. 304. Broadly oblong-oval, the elytra rapidly narrowed and sinuate at the sides behind ; body and antennte black, smooth and shining, the legs rufous ; under surface, legs and elytra covered rather densely with large oval white scales, which, on the elytra, are a little closer on the third and fifth intervals toward base and behind the middle ; pronotum more sparsely covered with elongate squamules, except a G08 Coleopterological Notices, IV. wide vitta at lateral sixth, which is more densely squamose. Beak glabrous but densely squamose near the base, rather stout, cylindri- cal and evenly, strongly arcuate throughout, distinctly punctate and nearly as long as the head and prothorax ; antennae very slender, nearly as in strialus, but with the first funicular joint as long as the next three. Prothorax slightly dilated, subparallel and broadly rounded at the sides, narrowed toward the apex and quite distinctly constricted but not tubulate, about four-fifths wider than long and one-half as long as the elytra, the base transverse, with the median lobe subobsolete; disk sparsely, somewhat unevenly, finely but distinctly punctate. Scutelluni extremely small, flat, equilatero- triangular. Elytra at base not quite as wide as the prothorax, very slightly longer than wide, the striae fine but abrupt, remotely and distinctly punctate, the intervals confusedly and minutely punctate. Pi'osternum separating the large anterior coxae by scarcely more than one-fourth of their own width ; tarsal claws small but slender, free and moderately divergent. Length 3.4-3.8 mm. ; width 1.6-1.8 mm. Florida (Baldwin). This species differs extremely from striatiis in many important structural characters, and is the only one which has been taken in any number. The scales are rather easily abraded. The epistornal lobe is very short and narrow, occup3nng the median third of the width, and limited at each side by a long deep oblique and arcuate fissure, the apex broadly sinuate in the middle ; in stri- aluH it is more than twice as wide, not at all advanced and is trans- versely' truncate at apex. ]VICE]\'TRIJS n. gen. The oblong-oval, sometimes almost cylindrical and convex form of the body, will readily serve to distinguish the species of this genus from those of Centrinus, where the outline is more rhom- boidal. The beak is generally thick and rather short, differing but slightly in the sexes, often strongly compressed or flattened at the sides toward base, but, in contractus, becoming longer, cylindrical and almost impunctate, at least in the female. The antennae are inserted at about the middle in the female or slightly beyond in the male. Mandibles rather well developed, nearly straight in external outline, with their inner edge dentellate ; they are not decussate when closed, the form then being anteriorly prominent in angle or ogive. The prosternum may be either canaliculate and feebly bicarinate along the middle or perfectly flat, sometimes flat in the female and Coleopterological Notices, IV. 609 feebly impressed in the male, but always more or less narrowly separates the cox£e, and the ante-coxal corneous processes of the male, forming so characteristic a feature of Centrinus, are completely obsolete. The scutellum, legs and abdomen are nearly as in Cen- trinus, and the body is similarly squamose ; the mes-epimera are, however, much less frequently visible from above in the reentrant angle between the protliorax and elytra. Our species are not very numerous and may be recognized a.s follows : — Prosternum flat or approximately so. Anterior coxfe separated by less than one-half of their own width; Leak moderately stout and snbequal throughout. Squamules of the pronotum abruptly and broadly dense and conspicuous at the sides, and sometimes, also, narrowly along the middle, the vestiture of the intervening regions consisting of small and more or less inconspicuous squamules. Punctures of the pronotum contiguous and more or less longitudinally coalescent ; scales of the elytra disposed in a single even series on each interval 1 liiieicollis Punctures of the pronotum rather widely separated ; elytral scales dis- posed in one or more series on each interval, quite broadly confused on the third and still more broadly on the fifth 2 ingenuiis Squamules of the pronotum uniform in structure throughout and but slightly uneven iu distribution, usually larger and gradually a little denser toward the sides. Anterior coxse very approximate, sejiarated by about one-fourth of their own width or less. Protliorax about as long as wide, coarsely, rugosely but not very deeply sculptured ; body narrow 3 scitlllllS Prothorax distinctly wider than long, the body more broadly oval. 4 decipieiis Anterior cox?e smaller and separated by nearly one-half of their own width ; very small species ; prosternum perfectly flat. 5 effetus Anterior coxfe separated by distinctly more than one-half of their own width ; beak longer, more slender and almost impunctate ; body shorter and broader, the second funicular joint much longer 6 contractus Prosternum with a narrow and deep but squamose longitudinal impression, limited on each side by an obtusely prominent ridge ; beak very stout, especially toward base in the male 7 caillis 1 IVicentrus lineicollis Boh. — Sch. Cure, VIII, i, p. 221 (Cen- trinus). Oblong-oval, narrow, subparallel, convex, black, rather dull ; vestiture whitish, the slender scales of the upper surface distinct 010 Coleopterological Notices, IV. near the sides and along a narrow median line of the pronotum, and disposed in a nearly even single line along each elytral interval ; intermediate areas of the pronotum clothed with exceedingly minute setiB ; scales of the under surface broadly oval and dense, except toward the sides of the prothorax, where they are fine sparse and subdenuded. Beak stout, moderately arcuate, varying in length from scarcely as long as the prothorax to as long as the head and prothorax, the antennae inserted a little beyond the middle, the basal joint of the funicle as long as the next two, the second one-half longer than the third, the club moderate, oval, densely pubescent, with the basal joint much less than one-half the mass. Prasternum not impressed, feebly, transversely constricted toward the middle behind the apical margin, separating the anterior coxte in the male by less than one-fifth of their own width, but in the female by a much more appreciable distance. Length 2.3-3.5 mm. ; width 0.8-1.4 mm. The series before me is from Massachusetts, District of Columbia and Texas. The beak varies considerably in length, irrespective of the usual sexual difiference, which is not remarkably pronounced, and the elytral squanniles are sometimes distinctly shorter and broader. I have retained the name given by LeConte to this species, although it differs from Boheman's description of the Mexican type in its piceous-black and not rufo-ferruginous legs, and the statement "antenna apicem rostri propius insertie," is almost irreconcilable. It is quite probable that there are several closely allied species confounded here, but my material is not sufficiently extensive to properly define them. 2 IVicentrilS ingenuus n. sp. — Oblong-oval, black and somewhat shin- ing throughout, the legs with a feeble rufopiceous tinge; vestiture consisting of pale yellowish scales, broad and dense beneath, elongate and narrower on the elytra, where they are disposed in from one to two series on the intervals, the lines of the third and fifth wider and more conspicuous ; on the pronotum the squamules are very small, dark in color and entirely inconspicuous, except in lateral fifth or sixth, where they become abruptly broad, denser and pale yellowish, also visible along the median line especially toward base. Head finely but strongly punctured, the impression very feeble, not foveate ; beak moderately stout, cylindrical, deeply, densely punctate and subrugulose, not quite as long as the head and prothorax, strongly, abruptly bent at base and also strongly but more gradually arcuate toward apex ; anteuns inserted just beyond the middle, the basal joint of the funicle unusually short, not longer than the next two, the second much more slender than the first and fully three-fourths as long, subequal to the next two, club about as long as the four Coleopterological Notices, IV. 611 preceding joints combined. Prothorax one-third wider than long, the sides feebly convergent, broadly, evenly and feebly arcuate nearly to the apex, then gradually more strongly convergent, but not at all sinuate, to the apes, the latter truncate and one-half as wide as the base, which is straiglit and trans- verse, the lobe rather small but distinctly prominent ; disk with deep and moderately large punctures, which are perforate and rather widely separated, but somewhat unevenly distributed, the impunctate line narrow but distinct, even and entire. Scutellum very densely squamose. Elytra slightly wider than the prothorax and about four-fifths longer, the sides quite strongly convergent throughout, the apex somewhat narrowly rounded ; disk rather coarsely, deeply striate, the intervals from one-lialf to once wider than the grooves, closely, deeply, confusedly and somewhat coarsely punctured throughout. Abdomen densely squamose. Prosternum perfectly flat, separating the rather large coxse by one-fifth of their own width. Length 3.8-4.0 mm. ; widtK 1.7— 1.8 mm. Illinois; Iowa; Texas. This species is not closely allied to any other, although belonging- in the neighborhood of decipiens; it differs in its much more abbre- viated basal joint of the antennal funicle and very markedly in the nature of the pronotal sculpture and vestiture. The type is a female; in the male the beak is a little shorter and thicker, with the antennsB inserted at apical two-fifths. Three specimens. 3 ZViceiltrilS SCitulus n. sp. — Elongate-oval, convex, black and shining throughout, the legs somewhat piceous ; vestiture white, consisting of large dense scales beneath and narrower sparsely placed squamules above, the latter more evident toward the sides of the pronotura but not forming a defi- nite vitta, not denser along the median line ; on the elytra they form a single or partially double line on each interval. Head finely but deeply, rather closely punctured, not squamose, the impression entirely obsolete ; beak moderately thick, rather feebly, evenly arcuate, coarsely, deeply, linearly punctate throughout at the sides and longitudinally furrowed, nearly as long as the head and prothorax, the antennae inserted near apical two-fifths, the scape rather long but not attaining the eye, the basal joint of the funicle as long as the next three, the second one-half longer than the third, the club rather small, oval, densely pubescent, about as long as the preceding four joints combined. Prothorax very nearly as long as wide, the sides broadly, evenly, feebly arcuate and convergent anteriorly, becoming nearly parallel in basal two-thirds, the apical constriction completely obsolete ; apex truncate, fully one-half as wide as the base, the latter transverse and straight, the median lobe one-third the total width, prominent ; disk without distinct median line, the punctures coarse, not very deep and partially coalescent, forming longitudinal rugse. Scutellum quadrate, squamose, the apical angles acute and prominent. Elytra a little wider than the prothorax and almost twice as long, the humeri small but decidedly prominent, the sides behind them evenly and sensibly convergent, the aj^ex rather abruptly but not C12 Coleopterological Notices, IV. broadly rounded ; disk with fine deep and abrupt stria, the intervals flat, from two to three times as wide as the grooves, coarsely confusedly and moder- ately closely punctured.

The single specimen appears to be a male, and the species some- what resembles deplanata, differing in its distinctly narrower form, much smaller pronotal punctures and longer, more conspicuous dorsal vestiture, as well as the characters given in the table. 5 Liilinobaris deplanata n. sp. — Oblong, depressed above, moder- ately shining, brownish-black throughout, subglabrous, the squamules small narrow and very sparsely, almost uniformly distributed above and beneath.

The single specimen, apparently a male, represents a species en- tirely distinct from any other here described ia its more depressed form and coarse sculpture, and especially in the distinctly concave elytral intervals. From fabida, which it more closely resembles, it may be known by the shorter, less conspicuous vestiture, more slen- der beak and very much coarser sculpture of the pronotum. There are, judging by material which has been recently sent me, apparently a number of species in our Central States allied to deplanata and kibida, and their separation will prove to be a problem of some difficulty. t) L.imno'baris puiictiger Lee. — Proc.

Represented by the unique type, which is in a rather poor state of preservation, being much rubbed ; it is apparent, however, from broken fragments, that the elytral scales are normally quite distinct, and that there are some scattered scales toward the sides of the pronotum. 7 Liiiuiiobaris deiilldata n. sp. — Oval, rather depressed, rufo-piceous throughout, the integuments shining, the vestiture consisting of very small sparse and yellowish squamules, only evident toward the sides of the pronotum and elytra, and, on the latter, especially near the apex ; on the under surface they are only distinct toward the abdominal apex. Head minutely, very remotely punctate, the impression strong, the beak rather stout, cylindrical, evenly, distinctly arcuate, not quite as long as the prothorax, minutely, line- arly punctate, more coarsely densely and rugosely so at the sides very near the base ; antennae inserted well beyond the middle, the first funicular joint as long as the next three, the second but slightly more than one-half as long as the first and about as long as the next two, outer joints gradually robust and almost continuous in outline with the club, which is very small, oval, scarcely longer than the preceding three joints together, densely pubescent throughout, and with the basal joint fully one-half the mass.

Abdomen with the first suture evident and strongly arcuate toward the middle, the first two segments moderately strongly, not densely punctured, narrowly and feebly impressed along the middle. Pro- sternum fiat, coarsely punctate, separating the coxje by distinctly more than their own width. Length 3.3 mm. ; width 1.3 mm. Florida. This species is not at all closely related to any other ; it is repre- sented by a single male. The si.xth funicular joint is longer than either the fifth or seventh, and the club is unusually small. Goleopterological Notices, IV. 633 8 I^ininobaris plaililiscula n.sp. — Oval, rather strongly depressed, polished, black, the elytra, legs and beak more or less rufous, the first some- what clouded with piceous toward the scutellum ; vestiture throughout above and beneath consisting of very small, remote and entirely inconspicuous setae. Head minutely, sparsely punctate, the transverse impression strong ; beak slender, cylindrical, equal throughout, evenly, rather feebly arcuate and not longer than the prothorax, smooth, minutely, sublineately punctured, more coarsely and confusedly so at the sides toward base ; antennae inserted just beyond the middle, the first funicular joint rather robust, as long as the next three, second but slightly longer than wide, a little longer than the third and scarcely more than one-third as long as the first, club moderate. Prothorax about as long as wide ; sides parallel and feebly arcuate to apical fourth, then broadly rounded, convergent and somewhat bioadly and feebly constricted to the apex, which is rather more than one-half as wide as the base, the latter transverse, the lobe small and feeble, rounded ; disk rather coarsely, deejjly, somewhat unevenly and closely punctate, the punctures always distinctly separated, the impunctate line narrow but evident. Scutellum small, fiat, glabrous, anteriorly parabolic, wider behind, the hind margin broadly, evenly arcuate. Elytra but just visibly wider than the prothorax and three-fourths longer, hemi-elliptical, rather acutely rounded at apex, the humeri not pro- minent ; disk with moderately deep strife, the intervals flat, scarcely more than one-lialf wider than the grooves, each with a single series of fine but deep, irregular and unevenly but generally remotely spaced punctures. Ab- domen shining, the first suture entirely obliterated except near the sides, the first two segments finely, very remotely punctured, the last three rather coarsely and much more closely so. Prosternum flat, the coxae remote, separated by a little more than theii' owu width, the subapical constriction distinct. Length 2.9 mm. ; width 1.0 mm. Texas. The sing-le specimen appears to be a female, the basal parts of the abdomen being entirely unmodified, but as the male impression is generally very slight indeed in this genus, it is not possible to be entirely certain of the se.x, especially in consideration of the short beak. 9 Liimnoliaris nasuta Lee. — Proc.

Length 3.7-4.4 ram.; width 1.35-1.75 mm. California (San Francisco) and Texas (El Paso). Numerous specimens. The male does not differ from the female b\^ any struc- tural peculiarities of note. 10 LiimilObaris Oblita n. sp. — Elongate-oval, moderately convex, strongly shining, tlie elytra minutely granulato-reticulate and slightly aliita- ceous, black throughout, the legs and antennje with a pioeous tinge, sub- glabrous, the vestiture excessively sparse throughout, the setae very small and inconspicuous. Head minutely hut strongly, sparsely punctate, the impression quite distinct ; beak slender, cylindrical, evenly, rather feebly arcuate, shining, finely, linearly and not very densely punctate, with two or three bristling squamules at the upper border of the eyes, about as long as the head and prothorax ; antennw inserted just beyond the middle, the basal joint of the funicle nearly as long as the next four, second barely one-half longer than the third, club oval, nearly as long as the five preceding joints combined, the basal joint composing three-fifths of the mass and sparsely pubescent toward base.

Prosternum flat, with a fine transverse impressed line behind the apex, the latter feebly sinuate in the middle; coxje ratJier large, separated by fully three-fourths of their own width. Length 3.5 mm. ; width 1.4 mm. Wisconsin. This species is not closely allied to any other and appears to form one of the transitions from the species with stout beaks and remote anterior coxae, to those with very slender straight beaks and more narrowly separated coxa;. The unique specimen is a female. 11 L.iinno'baris secllisa n. sp. — Oval, moderately stout, rather feebly, evenly convex above, shining, piceous, the legs rufous ; vestiture very uneven, consisting, on the pronotum, of large broad and pale scales toward the sides and before the scutellum, the scales becoming narrower and posteriorly oblique anteriorly and toward the middle, elsewhere dark in color, smaller and incon- spicuous ; on the elytra the large pale scales form a short line on the third interval behind the middle, and several small spots along the base, elsewhere narrow, elongate, darker and of different sizes from very minute setae to con- spicuous scales ; on the under surface they are elongate and rather sparse tliroughout. Head almost completely impunctate but minutely granulato- reticulate, the impression distinct ; beak cylindrical, rather stout toward base, evenly, feebly arcuate, with bristling scales just before the eyes, a little longer than the head and prothorax in the female, but not quite as long as the pro- thorax in the male, rather coarsely, sublinearly punctate ; antennae inserted at the middle in the female or distinctly beyond in the male, the basal joint of the funicle as long as the next three, second but slightly longer than the third, club moderate, the basal joint forming much more than one-half the mass, densely pubescent but gradually more sparsely so and slightly shining toward base. Prothorax nearly as long as wide, the sides parallel and scarcely arcuate to apical third, then broadly rounded and convergent to the apex, which is about one-half as wide as the base; apical constriction almost obso- lete; base transverse, broadly bisinuate; disk with a wide entire and con- spicuous polished impunctate line, the punctures coarse and dense. Scutellum small, glabrous, a little longer than wide. Elytra slightly wider and about one-half longer than the prothorax, evenly hemi-elliptical, the humeral callus feeble ; disk vvitli rather fine, moderately deep, finely, conspicuously and re- motely punctured striae, the intervals flat, fully twice as wide as the grooves, finely, confusedly, very deeply hut not densely punctate throughout.

Arizona,; Southern California. The general characters of the abov^e description are drawn from the female ; in the single very small male before me, the prothorax is quite distinctly wider than long, with the apex three-fifths as wide as the base. The great disparity in the length of the beak is, how- ever, the only very prominent sexual difference. In certain general characters of sculpture and vestiture, seclvsa makes an excellent transition from the normal forms of this subgenus to grisea. II. 12 L.iinno'baris grisea Lee. — Proc. Am. Phil. Soc, XV, p. 312 (Cen- trinus). Oblong-oval, moderately convex, piceous-black, the elytra and legs rufous; vestiture consisting of large elongate-oval yellowish- white scales, not contiguous beneath except in anterior two-thirds of the met-episterna; on the pronotum they are still more elongate, denser near the sides and finest and sparsest at lateral fourth ; on the elytra they are broadly oval and unevenly disposed in strongly marked lines along the intervals, the line of the third interval being especially wide and conspicuous. Head glabrous, minutely, sparsely and feebly punctate, the impression very feeble ; beak cylindrical, rather stout, evenly and rather strongly arcuate, as long as the head and prothorax in the female, but only as long as the latter in the male, the basal joint of the funicle as long as the next four together, the second as long as the next two, outer joints very short and transverse ; club in the male large, densely pubes- cent, as long as the six preceding joints together, oval, pointed, the rings decreasing abruptly in transverse diameter, the basal joint much less than one-half the mass. Prothorax coarsely, closely punctate, two-thirds wider than long, the sides subparallel in basal two-thirds, then strongly rounded and rapidly convergent but not- distinctly constricted to the apex, basal angles obtuse, the mes- epimera strongly exposed from above. Scutellum rather large, quadrate, glabrous, but indented and setose at each side. Elytra a little wider than the prothorax and about twice as long, hemi-ellip- tical in outline, the strife fine, the intervals strongly, confusedly punctate and from two to more than three times as wide as the grooves. Length 3.4 mm.; width 1.65 mm. The three specimens before me are from Arizona and New Jersey ; it was originally described from Texas. In the female the antennal Coleopterological Notices, IV. G37 club is notably smaller than in the male, and the funicle is longer and more slender, but aside from the shorter beak of the male I do not observe any other sexual differences. HI. 13 Lininobaris conflisa Boh. — Sch. Cure, III, p. 740 (Centrinus). Oblong-oval, subdepressed, alutaceous, black throughout, the antennae slightly paler ; integuments subglabrous, the vestiture consisting of very small fine white squamules, sparsely disposed above and beneath. Beak in the male rather stout, cylindrical, finely, densely punctured and squamulose toward base, straight in basal two-thirds, then bent, scarcely more than three-fourths as long as the prothorax, theantennaj inserted distinctly beyond the middle, the basal joint of the funicle robust, not as long as the next three, the second small, obconical, one-half longer than wide, the club moderately stout, oval, densely pubescent and nearly as long as the preceding five joints combined. Prothorax slightly wider than long, sides parallel and feebly arcuate, rounded convergent and con- stricted toward apex, the latter one-half as wide as the base; punc- tures fine, not very close-set, the impunctate line distinct. Elytra a little wider and three-fourths longer than the prothorax, hemi- elliptical, the humeral callus large but feeble; stria? fine, the inter- vals flat, wide, finely and more or less confusedly punctate. Pro- sternum separating the coxae by two-thirds of their own width or less, with two slender slightly contorted ante-coxal spiniform pro- cesses, which are very oblique, and immediately before which there is a large deep excavation. In the female the beak is more slender, more evenly and distinctly arcuate, smooth, polished and evidently punctured only near the base, not longer than in the male, being about three- fourths as long as the prothorax ; the prosternum is flat and the intercoxal process is not noticeably wider than in the male. Length 2.7-3.5 mm.; width 1.1-1.5 mm. In the description of Boheman, the beak is said to be as long as the prothorax in the italicized diagnosis, but as long as the head and prothorax in the description which follows, the fact being, if I have correctly identified the species, that it is much shorter than the prothorax in both sexes. In the description referred to I cannot comprehend the allusion to a " pygidium." The material before me includes series from Florida. North 638 Coleopterological Notices, IV. Carolina, New York, Indiana, Nebraska and Colorado, some being smaller, others larger, some with the male prosternal spines short, others so long as to nearly attain the anterior margin. The want of any accurate definition of the species deters me, however, from further investigation of these forms, although from the constantly small size and less developed aute-coxal processes of several good series, collected in definite localities, it is possible that two or three species or subspecies may be commingled. This species is said to occur in California (Mann. Bull. Mosc, 1843, 2d, 293), but I have not seen any specimens from that region. 14 lyinmobaris eliena n. sp. — Oblong-oval, moderately convex, pol- ished, black throngliout ; vestiture above and beneath consisting of small and Very sparse slender white squamules, much less conspicuous than in concinna, but more so than in confinis, unevenly sublineate on the elytra. Head minutely, scarcely visibly punctate, the constriction feeble but distinct, caused by a slight gibbosity at the base of the beak, the latter very slender, evenly cylin- drical, almost straight, much longer than the head and prothorax, shining, moderately punctured ; antennse inserted scarcely at all beyond the middle, slender throughout, the basal joint of the funicle as long as the next three, the second nearly two-thirds as long as the first and equal to the next two, the club very slender, fusiform, not abrupt, densely, coarsely pubescent and rather longer than the preceding four joints combined, the basal joint com- posing nearly one-half of the whole. Prothorax nearly one-third wider than long, the sides just visibly convergent from the base to the distinct apical constriction, and broadly, evenly arcuate ; apex one-half as wide as the base, the latter transverse, the median lobe small and feeble ; mes-epimera strongly exposed from above ; disk rather finely, not deeply and somewhat sparsely punctate, the impunctate line distinct. Scutellum small, quadrate. Elytra oblong, one-third longer than wide, distinctly wider than the prothorax and fully twice as long, the sides parallel and nearly straight, slightly rounded at base to the prothorax and very broadly rounded in apical third ; disk with deep, very even, abrupt grooves, the intervals from two to three times as wide as the stride, finely feebly and sparsely punctate, the punctures forming rather even series on the second, fourth and sixth, but confused on the others. Abdomen finely, feebly and sparsely punctate. Prosternum broadly, feebly impressed, separating the coxae by three-fourths of their own width, the transverse subapical impression even, distinct, with a small impressed pit adjoining it anteriorly. Length 3.8 mm. ; width 1.65 mm. Texas. One female example. This species is allied to coiifinis, but is more robust, with a longer beak in the female, more widely sepa- rated anterior coxte and more distinct squamules. With the type I associate a male and female from Indiana, which Coleopterological Notices, IV. 639 differ only in being a little less robust and less polished, with the beak in the female not longer than the head and prothorax, and, in the male, distinctly shorter than the latter, this sex having two long slender prosternal processes. 15 Liiiuiioliaris puteifer n. sp. — Oblong-oval, moderately convex, black, rather shining and subglabrous throughout, the vestiture consisting of very minute remote setiform squajnules, more distinct beneath than above. Head minutely, sparsely punctured, deeply inserted, the transverse constric- tion very feeble ; beak in male rather stout, evenly cylindrical, feebly arcuaie, three-fourths as long as the prothorax, roughly, deeply punctured and sparsely squamulose ; antennae short, inserted beyond the middle, the basal joint of the funicle i-obust, not as long as tVie next three, the second one-half longer than wide and one-half longer than the third, outer joints gradually trans- verse and coarctate, club nearly as in cnnfinis. Prothorax about one-third wider than long, the sides feebly convergent from the base and slightly arcu- ate, the apical constriction strong ; apex a little more than one-half as wide as the base, the latter transverse ; median lobe very small, feeble ; disk alu- taceous, rather finely sparsely and not deeply jjunctate, the impunctate line passing only slightly beyond the middle. Scutellum small, oblong. Elytra nearly one-third wider than the prothorax and two and one-half times as long, oblong, parallel, evenly rounded in apical third, tlie humeri scarcely promi- nent ; disk rather finely, abruptly, evenly striate, the intervals flat, about three times as wide as the grooves, each with a single series of fine remote punctures. Abdomen rather closely punctured toward the sides, sparsely in the middle, the punctures fine. Prosternum with a large oval extremely deep excavation in the middle, and with a short straight acute and very oblique process before each coxa, the coxae separated by two-thirds of their own width. Length 3.0 mm. ; width 1.25 mm. Indiana ? This species bears an extreme resemblance to confinis, being identical in sculpture and vestiture, but the ante-coxal processes are much more developed, the elytra relatively wider and longer, the second joint of the antennal funicle more elongate, and the pro- sternum differs radically in having a large extremely deep median excavation. A single male, without definite indication of locality, but in all probability from the region indicated. 16 L.ininobaris confinis Lee. — Proc. Am. Phil. Soc, XV, p. 317 (Centrinus). Oblong-oval, moderately convex, black throughout, shining, sub- glabrous, the vestiture consisting of very small sparse and subre- cumbent seta3 which, on the elytra, are arranged in single incon- spicuous series.

Prothorax subconical, slightly wider than long, the sides evenly, feebly arcuate, the apical constriction distinct; apex three-fourths as wide as the base; punctures rather fine, shallow and sparse, the impunctate line distinct. Elytra oblong, parallel, obtusely rounded l)ehind, distinctly wider than the prothorax and more than twice as long; striae fine, abrupt; inter- vals fully three times as wide as the grooves, each with a single series of minute, extremely distant punctures. Prosternum broadly, very feebly impressed, with a feeble elevated cusp before each coxa, and a small foveiform pit just behind the apex, the coxiie separated by three fifths of their own width. Length 2.3-2.9 mm; width 0.9-1.2 mm. The four specimens before me are from New York, Virginia, Iowa and Texas, the latter being the only female. In this sex the beak is very slender, cylindrical, nearh' straight, as long as the head and prothorax, and the antennos are longer and with a more slender club, but, as the elytral punctures are not by any means so distinct as in the northern specimens, it may not actually belong to this species. 17 L.imnol>aris COnclirreilS n. sp. — Oblong-oval, distinctly convex, lilack, moderately shining and siibglabrous throughout, the minute slender setiform squamules very sparse above and beneath, forming single series on the elytra.

Abdo- men feebly, not closely punctured. Prosternum broadly, very feebly impressed along the middle, witli a small feeble subtransverse fovea behind the apex, the sides of the longitudinal impression slightly prominent in the form of a low obtuse ridge for a short distance before each coxa, but without trace of ante- coxal cusp, the coxse separated by slightly less than one-half of their own width. Length 2.2-3.2 mm. ; widtli 0.85-1.4 mm. District of Columbia. Mr. Jiilich. The above description is drawn from the male. In the female the beak is slightly more slender very feebly arcuate and as long as the head and prothorax, with the auteunaj inserted at or just behind the middle. The antennte arc longer and more slender, the second funicular joint almost as long as the next two, and the prosternum is perfecth^ fiat, separating the coxie by fully three-fourths of their own width. Goncurrens is allied to conjinis, but differs in its much longer beak, especially in the male, and by its narrower an- tenaal club. Numerous examples. 18 L.iinilo1)aris COUCilina Lee. — Proc. Am.

Length 2.5 mm. ; width 1.0 mm. Florida. The three specimens before me are males, the abdomen having- a small elongate-oval and rather deep subbasal impression. The species is related to confusa, but differs in its small size, uniseriate elytral intervals, simple male prosternum and slightly longer beak. From covfinU it differs in its broader, more depressed form, much coarser elytral striae and larger, more close-set serial punctures. 20 Linilioliaris seminitens n. sp. — Elongate-oval, feebly convex, moderately shining, minutely reticulate, the pronotum alutaceous, black, sub- Goleopterological Notices, IV. 643 glabrous, tlie small fine squamules very sparse throughout.

Scutellum small, subquadrate, slightly broader behind. Elytra but little wider than the prothorax, fully twice as long as the latter, parallel, evenly rounded in apical third ; humeri scarcely at all prominent ; disk with fine abrupt rather deep and even striae, the intervals flat, fully three times as wide as the grooves, each with a single series of fine, feeble, rather distant punctures, confused toward the base of the third. Abdomen finely, sparsely punctured, but, as usual, densely so toward apex. Presternum flat, with a small subapical pit, the coxse separated by one-half of their own width. Length 3.5 mm. ; width 1.4 mm. Nebraska. Not closely allied to any other species known to me, and repre- sented by a single specimen which is undoubtedly the female, although the abdomen has a small feeble subbasal impression, and the fifth segment a small rounded indentation. A specimen in ni}^ cabinet from Florida also belongs apparently to this species, but is larger and with a much longer beak. IV. 21 Liniliobaris prolixa Lee. — Proc. Am. Phil.

Presternum broadly but strongly impressed along the middle in the female ; in the male it has a deep rounded pit near the middle, and, before each coxa, a slender process which is much more developed than in an}' other of our apygidiate Barini, projecting very nearly as far beyond the apical margin of the prosternum as the distance between the latter and the coxte, the apices diverging horizontally toward apex in order not to interfere with lateral movements of the beak ; coxre separated by nearly one-third of their own width. Length 2.3-3.4 mm.; width 0.75-1.1 mm. Illinois and Michigan. I also associate with this species a num- ber of specimens taken by Mr. Wickham at Greeley, Colorado, which seem to be merely a little smaller in size; in the single male, however, the prosternal spines are very much shorter, only project- ing as far as the anterior margin. I do not notice the bronzy lustre mentioned by LeConte. 22 L.iiiiiio'baris nitidissillia n. sji. — Very elongate, parallel, convex, highly polished, black with a rather strong seneous lustre ; legs pale, bright rufo-testaceous ; integuments subglabrous, the minute setse very sparse above, slightly longer and more evident toward the sides of the pronotum, only dis- tinct beneath on the met-episterna, where they are broader, somewhat dense and squamiform. Head very minutely, sparsely punctate, the impression almost obsolete, broadly subfoveate in the middle ; beak very slender, straight in basal half, gradually feebly arcuate and rufescent thence to the ajDex, smooth, cylindrical, punctate at the sides toward base and fully as long as the head and prothorax ; mandibles small, strongly arcuate, thick, deeply notched and unevenly bidentate at apex, and with two or three strong denticles ex- ternally toward base; antennse inserted at basal two-fifths, slender, the scape just attaining the eye, basal joint of the funicle not quite as long as the next three, second one-half longer than the third, club moderate. Prothorax about as long as wide ; sides straight and parallel fully to apical third, then broadly rounded, convergent and sinuate to the apex, which is two-thirds as wide as the base, the latter transverse, the median lobe extremely feeble ; disk with a feebly defined, incomplete median line, the punctures minute and very sparse. Scutellum small, quadrate, glabrous. Elytra quite distinctly wider than the prothorax and two and three-fourths times as long, parallel, the Coleopterological Notices, IV. C45 sides feebly convergent in apical third, the apex narrow but obtusely rounded ; humeri slightly prominent ; disk nearly as in prolixa, but with the punctures still moi'e minute and feeble. Prosternum strongly impressed along the mid- dle, separating the coxae by fully one-third of their own width. Length 4.1 mm. ; width 1.35 mm. Texas (Galveston). A single female. This species may be recog-nizecl at once by its polished seneous surface and red legs; it differs greatly from prolixa in the latter respect, and also in its longer beak, y. 23 Limnobaris longula Lee. — Proc. Am. Phil. Soc, XV, p. 31G (Centrinus). Elongate-oval, convex, black, the tarsi and antennae somewhat pale, shining, the vestiture white, consisting of long, slender, rather sparse but conspicuous squamules, almost evenly distributed above and beneath, becoming shorter and squamiform on the sternal para- pleurce. Head finely, sparsely punctate, the constriction obsolete, the frontal fovea very small and prolonged anteriorly for a short distance ; beak in the female moderately slender, slightly thicker toward base, cylindrical, smooth, polished, evenly, moderately arcuate, about. as long as the head and prothorax, almost impunc- tate but abruptly densely so and with erect squamules before the eyes; antennae inserted a little behind the middle, the basal joint of the funicle not as long as the next three, the second scarcely two- thirds as long as the first and as long as the next two ; club mode- rate, densely pubescent, not very slender. Prothorax two-fifths wider than long, the sides broadly, feebly arcuate, becoming conver- gent and gradually broadly and just visibly sinuate to the apex, parallel toward base, the apex nearly three-fifths as wide as the base; disk rather strongly, not very densely punctate, with a narrow im- punctate line. Seutellum small, glabrous. Elytra scarcely at all wider than the prothorax and about twice as long, hemi-elliptical, the stria3 not very coarse, wMth the edges finely, feebly, unevenly, subcrenulate, the intervals finely, sparsely, unevenly, punctured and transversely, unevenly rugulose. Prosternum strongly impressed along the middle, separating the anterior coxae by fully three-fourths of their own width Length 4.0-4.3 mm.; width 1.65-1.8 ram. Texas and Florida. In the original type, from which the above description is taken, the abdomen has, near the base, a narrow 646 Coleopterological Notices, IV. elongate and very feeble impression ; it is however a female, as is conclusively shown by the polished, almost impunctate beak ; the impression is spurious, and has very nearly misled me in several species of genera allied to this. There are but two examples known to me, and the Florida specimen in my cabinet is a male, a little larger than the Texas type, intense black throughout, the beak short, rather thick, cylindrical, densely, deeply lineato-punctate, evenly, feebly arcuate and distinctly shorter than the prothorax, the antenna? being inserted at apical two-fifths; otherwise the two specimens seem to agree very well indeed, except that the male is a little stouter and with less elongate elytra, rather the reverse of what might be expected. 24 Lininobaris rectirostris Lee. — Proc. Am. Phil. Soc, XV, p. 315 (Ceiitiinus). Elongate-oval, convex, black, polished, the pronotum slightly alutaceous, subglabrous, the vestiture consisting of minute slender white squamules, very sparse throughout. Beak in the male scarcely as long as the prothorax, thick, densely punctate, evenly cylindrical throughout, compressed and carinate above, the frontal constriction obsolete but represented by a large deep and transversely angulate fovea ; antennas inserted at the middle, the second funicular joint nearly as long as the first and as long as the next two ; club mode- rately stout, elongate-oval, densely pubescent, as long as the four preceding joints combined, and with the basal joint constituting two-fifths of the mass. Prothorax not quite as long as wide, feebly subconical, the sides more strongly arcuate before the middle, the apex two-thirds as wide as the base ; punctures rather uneven in distribution but generally not very close ; median line distinct. Elytra but little wider than the prothorax and much more than twice as long, the strife fine, abrupt; intervals wide, finely, feebly, rather sparsely and transversely punctate, the punctures confused on the third, but more or less evenly uniseriate on the others. Pro- sternum broadly sinuate at apex, strongly, transversely constricted behind the apex, broadly, feebly impressed along the middle, sepa- rating the coxae by one-half their own width. Length 4.2-4. T mm. ; width 1.7-1.9 mm. Indiana and Illinois. In the female the beak is very slender, evenly but extremely feebly arcuate and fully one-half longer than the prothorax, the prosternum flat. In three of the four males Coleopterological Notices, IV. 647 before me the beak is a little longer than the prothorax, with the frontal fovea much more feeble, the body more slender and the pro- sternum perfectly flat along the middle, l)at they are otherwise so similar to the form which I regard as typical, that I hesitate to describe them under a separate name. 25 L.inino'baris calva Lee. — Proc. Am. Phil. Soc, XV, p. 314 (Cen- trinus). Oblong, convex, moderately shining, the very small slender squa- mules sparse and inconspicuous above, but more distinct beneath, although still sparse. Head without trace of the feeblest transverse impression, but with a minute subobsolete median puncture, the beak in the male stout, shining but deeply, rugosely punctured, feebly compressed and subcarinate above, equal in length to the prothorax, straight, broadly bent near the middle and thence feebly flattened to the apex ; antennge inserted slightly beyond the middle, slender, the second funicular joint much longer than the next two; club slender, pointed, as long as the preceding four joints combined. Prothorax distinctly wider than long, the sides strongly, evenly rounded at apical third to the constriction, the apex tubulate and slightly wider than one-half the base ; disk not very coarsely but deeply and somewhat densely punctate, the impunctate line narrow and not attaining the apex. Scutellum small, quadrate. Elytra two-fifths longer than wide, scarcely at all wider than the prothorax and barely twice as long, obtusely rounded behind ; sides distinctly convergent throughout; disk finely striate, the intervals from two to three times as wide as the grooves, coarsely, confusedly, rugosely but not very densely punctured. Abdomen very closely punctured. Prosternum obsoletely impressed along the middle, separating the 00X86 by barely more than one-fourth of their own width. Length 5.2 mm.; width 2.2 mm. Pennsylvania, Georgia and Florida. The male has a small elon- gate-oval feeble impression near the base of the abdomen. In the original type the sides of the prothorax are parallel and almost per- fectly straight nearly to apical third, Init in other specimens they are slightly convergent and strongly arcuate; in the Pennsylvania male the legs are black and the interstitial punctures coarse, while in another exami)le the legs are red and the punctures finer. The description is drawn from the type specimen. 648 Coleopterological Notices, 1 V. OLIGOLOCHUS n. gen. The single species referred to this genus, greatly resembles Micro- cholus atriatuH in its general features of form, sculpture and vesti- ture, although much smaller in point of size, and would have been referred to Microchokis were it not for the distinctly different struc- ture of the mandibles, which are not large and prominent as in that genus, but very small, thick, strongly arcuate, notched at apex and broadly decussate when closed. The principal generic characters have been given in the table, and those of minor importance are referred to in the description of the single species given below. Oligolochus does not resemble Zygo- baris either in habitus or structure. 1 Oligolochus COiiTexils Lee. — Proc. Am. Phil. Soc, XV, p. 422 (Zygobaris ?). Oval, moderately and evenly convex, polished, black, the legs rufous ; vestiture very sparse and uneven, white, consisting of large scattered scales towards the sides of the pronotum and on the median line before the scutellum, also on the elytra toward the base of the third and fifth intervals and a few widely scattered on the disk toward the sides, the latter smaller and narrower ; on the under surface sparse but more evident on the sternal parapleural ; all other punctures of the upper surface bearing extremely minute seta?. Beak moderately slender, evenly, not very strongly arcuate, coarsely, sparsely, unevenly punctate at the sides, as long as the prothorax, feebly thickened toward base and slightly flattened toward apex, the basal impression extremely feeble ; antennce inserted a little beyond the middle, the scape almost attaining the e3"e, the first funicular joint longer than the next three, the second small, slightly longer than the third ; club moderate, abrupt, oval, densely pubes- cent, as long as the preceding four joints, with the basal joint one- half of the whole. Prothorax one-third wider than long, the sides very feebly convergent and distinctly arcuate from the base to the well-marked subapical constriction, the apex not tubulate, three- fifths as wide as the base, the median lobe of the latter small and feeble ; impunctate line entire ; punctures coarse, not dense. Scutel- lum very small, quadrate, impressed behind, glabrous. Elytra but slightly longer than wide, a little wider than the prothorax and three-fourths longer, hemi-elliptical, the apex narrowly subtruncate; Coleopterological Notices, IV. 649 humeri rather prominent; stride rather coarse, deep, abrupt, one-half to two times wider than the grooves, each with an uneven single series of small, not very close-set punctures, more confused on the third. Abdomen closely, rather coarsely punctate, the fifth segment not as long as the two preceding, the pygidium slightly exposed at tip in the male. Length 2.3 mm.; width 1.2 mm. Florida (Enterprise). Cab. LeConte. Represented by the unique male type. The presternum is flat, the subapical constriction fine, even and continuous entirely across the surface and not obsolete at the middle as stated by LeConte ; the surface between the constric- tion and the apex being rather strongly reflexed over the basal part of the head, the author quoted quite pardonably mistook the groove for the apical margin. The anterior coxte are separated by dis- tinctly less than one-half (jf their own width. The legs are more slender than in 3Iicrocholus striatus, but the tarsal claws are very nearly similar, thick and approximate, though divergent and free at base. IDIOSTETHUS n. gen. This genus, though related to Stethobaris, is conspicuously dis- tinct in antennal and pectoral structure, as well as in the general nature of the sculpture and vestiture. The antenna have the second funicular joint elongate when compared with that of Stetho- baris, and the club is generally smaller than in that genus; the club varies, however, quite remarkably in size and structure. The prosternum is noticeably tumid, especially before the coxjb, reminding us in this respect of Orthoris, and the narrow, deep but not abruptly defined median canaiiculation is formed in much the same manner, as a depression between the ante-coxal prominences. The coxiE are much more approximate than in Stethobaris, never being separated by more, and generally by less, than one-third of their own width. The pronotal sculpture is always in greater or less part longitudinally rugulose, and the vestiture con.sists of small sparse slender and recumbent seta? and squamules, the latter, in one of the species, widely dispersed over the elytra; they are generally, but not always, more distinct toward the sides of the body beneath, occasionally becoming conspicuously dense. In the short tubulate prothorax, structure of the beak, mandibles and transverse frontal impression, scutellum, legs and tarsi, Idio- stethus closely resembles Stethobaris, but the body is more elongate- C50 Coleopterological Notices, IV. oval, with less prominent and especiall}^ less post-basal humeri, and the small, slender tarsal claws are more widely divergent. The four representatives here recognized may be easily identified from the following characters, the species being more isolated among themselves than in Stethobaris : — Elytra without dispersed sqnamules, the anteniial scape more abruptly clavate. Antenuse with the first funicular joint not longer than the next three to- gether ; club smaller, with its basal joint constituting about one-half of the mass ; vestiture not dense at the sides beneath. Sculpture coarse, the pronotum with a narrow, impunctate and generally subcarinate line ; interstitial punctures of the elytra coarse and deep ; larger species 1 tul>lllatll8 Sculpture finer, the pronotum very finely, densely rugulose and without median line ; interstitial punctures smaller, rather indefinite and feeble ; much smaller species 2 subcal'VUS Antennae with the first funicular joint as long as the next four ; club larger, elongate, nearly as long as the jireceding six joints combined and with its basal joint constituting but slightly more than one-third of the mass ; vesti- ture extremely dense at the sides of the body beneath.. .3 ellipsoideus Elytra with widely dispersed, longer, whiter but slender squamules ; antennal scape gradually clavate 4 dispersiIS 1 IdiostetllllS tu1)UlatlIS Say— Cure, p. 20; Ed.

Prothorax nearly three- fourths wider than long, the sides rather strongly convergent and straight to apical third, then broadly rounded and convergent to the strongly constricted and tubulate apex ; punctures coarse, deep, rather dense, more or less longitudinally confluent, and with a nar- row subcarinate impunctate line. Scutellum small, slightly wider than long, broadly emarginate at apex.

Length 3.0-4.0 mm. ; width 1.6-2.0 mm. New York, Pennsylvania, Indiana, Illinois and Florida, the latter locality perhaps doubtful. Nine specimens, exhibiting con- siderable variation, chiefly in regard to the magnitude and density of the punctures. In some specimens the thoracic sculpture is longitudinally and strongly rugulose. 2 IdiostetllllS SIl1>calVllS Lee. — Proc. Am. Pliil. Soc, XVII, p. 622 (Zygobaris).

Four specimens. 4 Idiogtethlis dispersus n. sp. — Oval, rather stout, moderately con- vex, black ; legs rufo-piceous ; integuments polished, the vestiture sparse and Coleopterological Notices, IV. 653 uneven, consisting, on the pronotum, of extremely minute set^ which hecome long slender recumbent whitish squamules in lateral fifth, and in the middle before the scutellum, also with a few widely dispersed over the intermediate regions ; on the elytra there is a single series of very small setae on each interval, with long slender squamules very widely dispersed over the entire surface ; on the under surface the squamules are denser and somewhat brist- ling on the presternum especially behind, and the smaller white recumbent scales are sparse throughout, but denser on the met-episterna and toward the sides of the last four ventral segments. Head finely, rather sparsely punc- tate, the beak moderately stout, densely punctate and sparsely squamulose along the sides, evenly, distinctly arcuate and equal in length to the protho- rax in the male; antennae inserted near apical two-fifths, the scape rather long and strongly, gradually clavate. Prothorax three-fourths wider than long, the sides feebly but distinctly convergent and nearly straight to apical fourth, then strongly rounded to the apical constriction, the apex briefly tubulate, rather more than one-half as wide as the base, the latter broadly, feebly arcuate, the median lobe very small and feeble ; disk very unevenly, moderately coarsely and deeply sculptured, the impunctate line narrow but entire, well defined and somewhat elevated; sculpture longitudinally rugu- lose toward the middle, closely punctate toward the sides, and more finely and very sparsely punctate at lateral fourth toward base.

The single specimen is a male, the abdomen having a rather small but deep subbasal impression. This species is not at all closely allied to tubulatus, and has the anterior coxae slightly less narrowly separated. STJBTHOBARIS. LeConte— Proc. Am. Phil. Soc, XV, p. 302. The essential characters distinguishing this genus from others, more closely allied to it in the present section of the tribe, are the large antennal club, nearly as long as the entire funicle and resem- bling that of Rhoptobaris, the small, slender, free but feebly diver- 654 Coleopterological Notices, IV. gent daws, deeply, abruptly and broadly excavated presternum, not very widely separating the coxae, peculiar oval, thick and con- vex form of the body, with prominent humeri situated at quite a noticeable distance behind the base, and the polished black integu- ments, Avhieh are practically entirely glabrous, each puncture bear- ing an excessively minute seta, only visible under considerable amplification. Stethobaris is one of the genera connecting the more normal forms of the tribe with the aberrant Oomorphidius and Eisonyx. The beak is separated from the head by a feeble but distinctly marked transverse in]pression and is strongly arcuate, moderate in length and thickness, and nearly always noticeably tapering from base to apex, with the antennal scrobes strongly oblique and broadly confluent beneath ; the mandibles are short, arcuate and broadly decussate. The tibixe are deeply and longitudinally sculptured. The species of Stethobaris are moderately numerous, and, with one exception, more than usually homogeneous in external appear- ance. It is possible, however, that they may be recognized by the characters given in the following table: — Integuments more or less finely and sparsely punctate, the interstitial punc- tures of the elytra very minute and sparse. Sides of the prothorax broadly arcuate, becoming parallel in basal half; pronotal punctures minute and very sparse, becoming larger but not at all confluent at the sides beneath 1 corpulenta Sides convergent from the basal angles, the prothorax smaller and more conical, less sparsely and more conspicuously punctured. Prothorax with a distinct but narrow subentire impunctate line ; punc- tures of the elytra confused, at least on the wider intervals ; sides of the prothorax beneath obliquely and finely rugose ; last ventral segment in both sexes distinctly shorter than the two preceding together. Elytral grooves very coarse, strongly, remotely punctured, the edges feebly but distinctly serrato-crenulate ; form stouter, the prothorax a little more transverse 2 incoiupta Elytral grooves less coarse, much more finely punctate at the bottom, the edges never serrato-crenulate, except occasionally very feebly so near the base 3 OTata. Prothorax more conical and more densely punctate, never with a clearly defined entire impunctate line, the punctures beneath at the sides dis- tinct, not forming elongate rugse ; elytral strije very coarse and remotely but conspicuously punctured, the extremely minute interstitial punc- tures forming a single line on each 4 congei'Iliaiia Integuments coarsely, densely punctured, the punctures of the elytra forming a single deep coarse and confluent line on each interval 5 egregia Coleopterological Notices, IV. 655 1 Stetliolbaris corpulenta Lee— Proc.

Robust, oval, convex, glabrous, strongly shining and black throughout, the antennae with the first funicular joint nearly as long as the next four, second to seventh equal in length, the former not as long as wide ; club large, evenly elliptical, densely pubes- cent, equal in length to the six preceding joints combined and equally trisected by the first and second sutures. The prothorax is short, four- fifths wider than long, the sides very strongly, evenly arcuate, convergent anteriorly to the strong apical tubulation, and becoming gradually parallel in about basal half, the apex not quite one-half as wide as the base, the latter broadly, feebly arcuate, the median lobe small but prominent, truncate ; disk sparsely, uniformly, very finely and rather feebly punctate, coarsely but not confluently so beneath, the impunctate line narrow, distinct and subentirc.

Elytra, at a short distance behind the apex, fully one- fifth wider than the prothorax, a little more than twice as long as the latter, the humeri obtusely prominent ; outline hemi-elliptical ; striffi coarse, deep, with the margins remotely and finely serrato- crenulate toward base ; intervals from two to three times as wide as the grooves, minutely, feebly, sparsely and confusedl\^ punctate. Length .3..S mm. ; width 1.8 mm. Florida (Tampa). Cab. LeConte. I have seen only the unique female type in the Museum of Comparative Zoology at Harvard University. 2 Stetliobaris incoiupta n. sp.— Oval, sti-ongly convex, somewhat robust, black, glabrous and strongly shining throughout. Head finely but strongly, sparsely punctate, the beak densely punctured at the sides, evenly, strongly arcuate, moderately slender, distinctly tapering from base to apex and equal in length to the head and prothorax, the antenuc-B inserted at basal two-fifths, nearly as in corpulenta, but with the first funicular joint a little shorter and the club distinctly longer, equalling the entire funiele excepting one-half of the basal joint, with its first joint a little hunger than the second. Prothorax about four-fifths wider than long, the sides feebly but noticeably convergent and nearly straight to the middle, then gradually, broadly rounded, becoming strongly convergent to the apical tubule, which is distinctly less than one-half as wide as the very broadly, feebly arcuate base ; median lobe of the latter small but distinct, truncate ; disk rather finely but deeply, not very densely punctate, with a narrow impunctate median line, the punctures coarser, and forming long oblique rugae beneath. Scutellum minute, quadrate, scarcely impressed. Elytra, at a little behind the base, barely one-fifth wider than the prothorax, nearly two and one-half times longer than the latter ; 656 Coleopterological Notices, IV. humeri obtusely prouaiueut ; outline behind them hemi-elliptical ; stride rather coarse, deep, remotely, distinctly serrato-crenulate, the intervals differing greatly in width, the third twice as wide as the grooves, the fourth but slightly wider than the latter, flat, minutely but deeply and distinctly punctate, the punctures confused, sparse but becoming closer toward base, forming nearly even single lines on the narrow intervals. Length 3.1 mm. ; width 1.65 mm. Florida. This species differs from corpulenia in its less obese form and larger antennal club, smaller and quite differently shaped, slightly more conical, much more coarsely, deeply and less sparsely punctate prothorax, with the punctures not isolated beneath at the sides, but forming long ruga? ; also in its flatter, still more unequal and less polished elytral intervals, with the punctures less minute, deeper and becoming denser toward base ; and finally, and quite remark- ably, in the form of the mes-epimera, which in corpulenta are gradually pointed upward, but much more truncate and rounded in incompta. The present species is closely allied to ovata, and agrees with that species in all the characters given above to distin- guish it from corpulenta. It is represented by a single female. 3 Stetliobaris ovata Lee. — Proc. Acad. Nat. Sci. Phila., 1868, p. 363 (Baridius). Ovate, polished, black and glabrous, rather strongly convex.

Length 2.8-3.0 mm. ; width 1.5-1.8 mm. Massachusetts; New York; Missouri. Easily distinguishable from ovata by its very coarse, strongly punctured and subcrenulate elytral stride, with the intervals uniseri- ately punctate throughout, by its less widely separated anterior coxi3e, less transverse, more rapidly conical and more coarsely, closely and evenly punctate pronotum, without a distinctly marked impunc- tate line, and by several other characters as stated in the table. 5 Stetlioliaris egregia n. sp. — Oblong-oval, convex, subglabrous, shining but deeply, densely sculptured, black, the elytra somewhat piceous.

Prothorax less transverse than usual, one-half wider than long, the sides feebly convergent and slightly arcuate to apical third, then rounded to the tubulate apex, which is one-half as wide as the base, the latter transverse, arcuate at the sides, the median lobe distinct ; disk with a small, ill-defined elongate impunctate spot behind the middle, the punctures coarse, deep, rounded, dense. Scutellum quadrate, small, strongly impressed. Ehitra somewhat al)ruptly nearly one-fourth wider than the prothorax, more than twice as long as the latter and distinctly longer than wide, the humeri moderately prominent, smaller and more basal than usual ; sides behind them only moderately convergent, the apex rather broadly and abruptly rounded ; disk with coarse deep very abrupt and non-crenulate grooves, the intervals flat, suhequal, but slightly wider than the grooves, each with a single series of coarse deej) confluent punctures. Length 2.8-3.1 mm. ; width 1.4-1.65 mm. Arizona. In one of the specimens before me the pronotal punctures ai'e very dense, almost in mutual contact, but in the other are separated by one-half of their own diameters, displaying, as in many other species, marked variation in the coarseness and density of sculpture. ZAGLYPTUS. LeConte— Proc. Am. Phil. Soc, XV, p. 23G. In this remarkably distinct genus, the body is minute and sparsely covered with long stiff erect bristles, the beak moderate in length, evenly, feebly arcuate, with the antennse inserted just beyond the middle, the prosternum broadly, rather feebly impressed along the middle, separating the coxse by much less than their own width, and the tarsi very slender, the third joint elongate, subcylindrical or feebly obconical and not in the least dilated. Zaglyptus was in- advertently placed in the Cryptorhynchini by its author. We have but two species, one of which I do not have before me at present; they are distinguished by LeConte as follows: — Elytra with coarsely punctured shallow striae, the intervals rather wide. 1 striatus Elytra deeply sulcate, the grooves punctured ; interspaces narrow ; color darker 2 sillcatus These species appear to be rare, or at least seldom taken ; they are probably of peculiar habits. Goleopterological Notices, IV. 659 1 ZaglyptllS Striatlis Lee. — Proc. Am. Phil. Soc, XV, p. 237. Oval, convex, dark red-brown, polished, the upper surface with a few fulvous prostrate hairs in addition to the long stift" seta3, more especially noticeable on the prothorax and toward the base of the beak. Beak quite distinctly longer than the head and prothorax, rather strongly, longitudinally sulcato, slightly punctate toward base ; antenna I'ather slender, the basal joint of the funicle robust, nearly as long as the next three, two to seven short, coarctate, sub- equal in length and gradually slightly thicker, club moderate. Pro- thorax conical, one-half wider than long, the sides feebly inflated and distinctly arcuate at the middle; apex one-half as wide as the base ; punctures distinct but not very dense. Scutellum small. Elytra at base abruptly barely one-fourth wider than the prothorax, about twice as long, not longer than wide ; sides broadly arcuate, becoming parallel near the base; disk with just visibly impressed series of rather coarse, deep, not very close-set punctures, the inter- vals nearly flat and fully twice as wide as the strial punctures- Length 1.4 mm.; width 0.8 mm. Pennsylvania and District of Columbia. The head is impunctate but minutely, densely granulato-reticulate ; it is not separated from the beak by a transver.se in)pression. This is the most minute baride known within our faunal limits. 2 ZaglyptUS sulcatum Lee— Proc. Am. PhU. Soc, XV, p. 237. Represented by the unique type almost similar in size to striatus. Alabama (Mobile). OOMORPHIDIUS n. gen. It is necessary to separate Microcholus erasus and bjevicoUis of LeConte as a very distinctly defined genus, forming a passage from Stethobaris to Eisonyx, and differing radically from Microcholus in its strongly convex body, tubulate prothorax, peculiarly modified elytral striation, impressed prosternura and stout, strongly decus- sate mandibles. In many of its most striking characters it resem- bles Eisonyx, and in fact is so evidently allied to that genus as to prove the feeble value of ungual structure in the present section of Barini ; this is shown also below in the case of Barinus and Bari- lepton, which are related in much the same way as Oomorphidius and Eisonyx. 660 ColeojJterological Notices, IV. Oomorphidius is distinguished by an oval, extremely convex and subglabrous body, rather long, moderately stout, arcuate beak, with broadly arcuate and somewhat advanced epistomal lobe, rather robust legs, with subarcuate femora, dilated third tarsal joint and very small, slender, free and divergent claws. The scutellum is minute. The two species differ subgenerically as follows : — Subgenus I. Apical constriction of the protliorax not extending across the dorsal surface ; prosternura narrowly and feebly sulcata, the sulcus squamosa along its edges ; anterior coxae apparently separated by less than one-third of their own width; elytra without dispersed squamules ; scutellum nearly as wide as long ; size larger, the elytra nearly as in Eisonyx and wider tlian the protliorax 1 erasus Subgenus II. Apical constriction in the form of a deep abrupt groove, extending without change in character entirely across the dorsal surface ; prosternum very broadly, moderately strongly subsulcate, the sides of the impression not well defined and completely glabrous; coxae separated by one-half of their own width ; elytra with a few widely dispersed squamules toward the sides and apex ; scutellum elongate, triangular ; size small, the protliorax much shorter and equal in width to the basal parts of the elytra. 2 laevicollis 1 Oomorphidius erasus Lee. — Trans. Am. Ent. Soc, VIII, p. 217 (Microcholus). Oval, very strongly convex, black, the legs slightly piceous, the antenna3 rufescent ; integuments smooth, almost completel}' gla- brous and very highly polished, the elytra slightly alutaceous. Head minutely, sparsely punctulate, the transverse impression broad and feeble ; beak rather long and somewhat stout, distinctly, evenly arcuate, sparsely, deeply punctate and fully as long as the head and prothorax; antennae inserted just behind the middle, the scape long, first funicular joint as long as the next three, the second one-half as long as the first and fully as long as the third and fourth com- bined ; club robust, moderate in size, abrupt, densely pubescent. Prothorax nearly one-half wider than long, the sides rather strongly convergent and nearly straight to apical third, then gradually rounded and convergent to the strongly tubulate apex ; base broadly, evenly arcuate throughout the width, the lobe obsolete ; disk sparsely, extremely minutely and feebly punctate throughout Coleopterological Notices, IV. 661 and glabrous. Scutellum very minute, triangular. Elytra nearly as in Eisouyx, broadest just before basal third, where the sides are broadly subangulate, one-fourth wider than the prothorax and a little more than twice as long, the sides strongly convergent behind and feebly arcuate, the apex narrowly subtruncate ; disk with but feeble traces. of fine impressed stria?, which are abruptly, deeply foveate just behind the basal margin, the intervals very minutely obsoletely sparsely and confusedly punctulate, entirely glabrous ex- cepting a few long recumbent yellowish squamules at the base of the second to fourth intervals. Prosternum narrowly and feebly sulcate along the middle, the sides of the sulcus with recumbent yellowish squamules, the coxffi separated by less than one-third of their own width. Length 4.3 mm.; width 2.3 mm. Kansas (Topeka). Cab LeConte. Stillrepresentedby the unique type. II. 2 Oomorpliidius laevicollis Lee. — Proc. Am. Phil. Soc, XV, p. 304 (Microoholus). Oval, very strongly convex, rapidly narrowed behind, dark rufo- piceous, the elytra blackish and the legs paler ; body almost gla- brous, rather alutaceous in lustre and minutely reticulate. Head almost impunctate, the impression very feeble ; beak finely, sparsely punctate, moderately long and slender, strongly, evenly arcuate and fully as long as the head and prothorax, the antenna? inserted at apical two-fifths, slender, the scape rather long, the first funicular joint robust, clavate, not as long as the next three, the second more slender, two-thirds as long as the first and fully as long as the next two combined, club not large, robust. Prothorax very transverse, twice as wide as long, the sides broadly rounded and gradually more convergent from the base to the apical constriction, which is in the form of a narrow deep groove extending entirely across the dorsal surface, the apex strongly tubulate ; base broadly, feebly arcuate ; disk excessively minutely feebly and sparsely punctured. Scutellum very small, elongate, triangular. Elytra a little longer than wide, two and one-half times as long as the prothorax and equal in width to the latter, with the sides straight and parallel to basal fourth, then, to the narrowly rounded apex, strongly conical with the sides nearly straight ; disk with very fine, nearly obsolete stria?, each terminatino- at some distance behind the basal margin in a mode- 662 Coleopferological Notices, IV. rately deep dilated fovea, the intervals not perceptibly punctulate, the surface glabrous, excepting three or four long slender white squanuiles widely dispersed laterally, and a few also at the base of the second and third intervals.

This remarkable species is still represented as far as I know by the unique type. EISONYX. LeConte— Trans. Am. Ent. Soc, VIII, p. 216. This is perhaps the most aberrant and specialized baride genus within our faunal limits. In general form it is totally unlike our other genera, but is satisfactorily connected in this respect by Oomor- ])hidius. The original diagnosis of LeConte will serve for its re- cognition, but is greatly misleading in several important points. The middle and hind tibiae are, for example, not in the least conical in outline, but are very thick and quite peculiar in structure, indi- cating perhaps a burrowing habit ; they are strongly carinate ex- ternally near the base, then straight for a short distance, then feebly bent outward, becoming distinctly dilated and densely bristling with fulvous setae. The el3'tral strife are not by any means replaced by series of coarse punctures, as stated in the original descrip- tion, the strife being all but completely obsolete, but marked by series of exceedingly minute feeble and distant punctures, and ter- minating at base in larger deep foveas as in Oomorphidius ; the large deep circular perforate and widely distant punctures referred to by the author, are unevenly spaced along the middle of the in- tervals. Each of these large punctures bears a very small slender seta, but some of them, which are widely isolated and a little larger than the others, bear instead a single large white recumbent scale. The beak is extremely thick, short, feebly arcuate and scarcely three-fourths as long as the prothorax, bristling with coarse erect setse at the sides toward apex, and the antennae are inserted slightly beyond the middle, the scrobes being very oblique. Scutellum minute, rather deeply seated, feebly tumid and nude. 1 Eisonyx crassipes Lee. — Trans. Am. Ent. Soc, VIII, p. 217. Rhomboidal, widest between basal third and fourth of the elytra, black, rather dull, finely alutaceous and smooth throughout, convex, Coleopterological Notices, IV. 663 the vestiture extremely unevenly distributed, consisting- of a cluster of elongate fulvous squamules among the deep coarse punctures occupying the lateral portions of the anterior thoracic constriction, also at the base before the scutellum and along the margin toward the sides, also with a few similar squamules near the base of the third and fifth elytral intervals; elsewhere on the upper surface, with the exception of the few widely scattered white scales of the elytra, the setge are very minute. Head almost impunctate, the beak sparsely but deeply so, separated from the head by a transversely arcuate shallow but sharply defined groove. Protborax finely, fee- bly and very sparsely punctate, as long as wide, convex, the sides feebly convergent from the base nearly to the apex and straight; base strongly, anteriorly oblique from the scutellum to each basal angle, the median lobe nearly obsolete. Elytra about one-half wider than the prothorax and nearly twice as long; sides about equally and strongly convergent anteriorly to the base of the pro- thorax, and posteriorly to the very narrow subtruncate and con- jointly arcuate apex, the sutural notch completely obsolete. Length 4.8 mm. ; width 2.5 mm. Texas — Cab. LeConte. But two specimens are known, one of which is in the cabinet of Dr. Horn. ZYGOBARIS. LeConte— Proc. Am. Phil. Soc, XV, p. 317. A single widely isolated subtropical species, with coarsely punc- tured elytral striae and very long .slender strongly arcuate beak, alone constitutes this genus as far as known. LeConte placed here, also, several other small and obscure forms ; these, however, belong to widely diverse genera, and have been described under the preced- ing Oligolochus and Idiostethus, and Catapastus which follows. Zygobaris may be distinguished easily by the structure of the tarsal claws, which are moderate in length and completely connate, without trace of suture, through at least one-third of their length. The mandibles are small, thick, arcuate, notched at apex and strongly decussate. Prosternum flat, separating the coxa? by about their own width, the subapical constriction feeble and only visible later- ally, represented in the middle by a small, moderately deep, sub- transverse fovea, limited at each side by a small longitudinal ridge. Other i-eneric characters are mentioned below : — 664 Coleopterological Notices, IV. 1 Zygoliaris nitens Lee. — Proc. Am. Phil. Soc, XV, p. 318. Robust, rhomboidal, moderately convex, strongly shining, black, the legs slightly piceous ; integuments subglabrous, the vestiture white, consisting of very minute and sparse setiform squamules, with large white scales remotely dispersed but more condensed at the base of the second elytral interval, more distinct but sparse beneath. Beak long and slender, evenly, strongly arcuate, slightly tumid at base with the constriction distinct, feebly compressed and densely punctured at the sides, especially behind the antennae, two- fifths as long as the body in the male and two-thirds in the female, smoother and less punctate in the latter sex ; antennas inserted at basal two-fifths in the female or a little behind the middle in the male, the scape nearly attaining the eyes, the scrobes almost com- pletely inferior, basal joint of the funicle not quite as long as the next four, the second one-half longer than the third ; club moderate, elongate-oval, densely pubescent, with the basal joint composing about one-third of the mass. Prothorax conical, one-half to two- thirds wider than long, the sides feebly, evenly arcuate ; constric- tion rather strong ; disk very coarsely, deeply, moderately closely punctate, without trace of impunctate line. Scutellum small, oblong, glabrous. Elytra at base much wider than the prothorax, rather more than twice as long as the latter, parabolic in outline, the humeral callus not laterally prominent; disk with very fine strige, which are widely and deeply impressed and coarsely, not closely punctate, the intervals convex, each with a single series of coarse deep remote punctures, about as large as those of the striae but more than twice as distant. Length 2.6-3.7 mm.; width 1.4-2.0 mm. Southern Florida. A distinct and easily recognizable species. CATAPASTUS u. gen. This genus contains some of the smallest centrinides thus far discovered, and is rather isolated. Its nearest relative is probably Zygobaris, but the divergence from even this form, which is itself a strongly specialized type, is very notable. The beak is short, stout, broad, flattened toward apex, very densely but finely punctate throughout, squamose and without trace of basal constriction. The antenn* are inserted distinctly beyond the middle, which contrasts greatly with their position in Z3^gobaris, the scape nearly auffusus. It also differs in having the met- episterna decidedly narrower, and the elytra covered with a dense crust of scales which entirely conceal even the stri«, the latter being indicated by wide partings of the scales in suffusus. 6 BariuilS llltescens Lee. — Trans. Am. Ent. Soc, VIII, p. 218 (Bari- lepton). Rather robust, oval, the upper surface only moderately convex, black, the legs piceous-black ; integuments shining, densely clothed with large ochreous scales, which are rather elongate, evenly dis- tributed on the elytra, where they become gradually semi-erect behind and denuded at the sides in more than basal half, also broadly dense at the sides of the pronotum, the median glabrous area oval in outline; under surface polished and with very minute remote setiform squamules, which are abruptly dense and broader on the met-episterna and at the sides of the abdomen behind. Beak thick, strongly arcuate and punctured at base, three-fourths as long as the prothorax, the transverse impression very broad ; surface glabrous but with a few very small, scarcely visible squamules near the an- terior margin of the eye ; basal joint of the antennal funiole as long as the next five ; club rather small, but slightly longer than the pre- ceding four joints combined. Prothorax fully one-third wider than long, the sides parallel and nearly straight in basal two-thirds, then broadly rounded, convergent and scarcely at all constricted to the apex, the latter scarcely more than one-half as wide as the base ; disk rather coarsely and sparsely punctate, the punctures becoming smaller and much denser anteriorly. Scutellum very small, tumid, quadrate, glabrous and polished. Elytra scarcely perceptibly wider than the prothorax and a little more than twice as long, parallel, parabolically rounded in apical two-fifths, the subapical sinuation Coleopterological Notices, IV. 6T3 very feeble and the sutural notch broad; disk rather finely striate, the intervals rather finely, moderately densely punctured. Proster- nuni rather deeply but very narrowly sulcate, the coxa? large, pro- minent, separated by scarcely more than one-fourth of their own width. Length 8.2 mrn. ; width 13 mm. Texas (Columbus). Cab. LeConte. The unique type is the only specimen which I have seen ; it is a female. This species is allied to albescens, in spite of the great dissimilarity in form of the body; the arrangement of the vestiture beneath is almost identical, but lutescevs does not possess the denuded subapical spot of the elytra, is much more coarsely punctate, and differs in so many characters that there cannot, I think, be the least doubt of its distinctness. 7 Barinus curticollis n. sp. — Rather narrowly oblong-oval, some- what convex, polished, black, the legs dark rufo-piceous ; vestiture yellowish, consisting, on the pronotum, of dense elongate-oval scales in lateral third, on the elytra of nearly similar scales almost uniformly but not very densely dis- tributed throughout, becoming finer and still sparser on the flanks, very sparse throughout beneath, except on the met-episterna, where they are much denser, also denser at the sides of the last three ventral segments. Head dull, finely, sparsely punctate, the impression distinct ; beak short, thick, very strongly arcuate, not as long as the prothorax, coarsely but sparsely punctate, some- what squamulose above the eyes ; antenna slender, the basal joint of the fuui- cle not quite as long as the remainder, club moderate. Prothorax short, two- fifths wider than long, the sides parallel and straight to apical third, then gradually rounded convergent and nearly straight to the apex, which is three- fifths as wide as the base, the latter transverse, the median lobe broad and feeble ; disk coarsely, rather sparsely punctate, the punctures round, deep, perforate and isolated, with a narrow and irregular impunctate line. Scutel- lum small, oval, tumid and glabrous. EUjtra slightly wider than the prothorax and nearly two and one-half times as long, elongate hemi-elliptical, obtusely rounded at apex, the humeri not laterally prominent ; disk deeply striate, the intervals flat, from two to three times as wide as the grooves, coarsely, con- fusedly but not very densely punctate. Abdomen finely, remotely punctate, the basal segment coarsely and much more closely so. Anterior coxfe sepa- rated by about one-half of their own width. Length 2.7-3.0 mm. ; width 1.0-1.2 mm. Missouri ; Louisiana. The description is drawn from the male, the abdomen having a small deep elongate-oval impression near the base. This species is allied to lutescens, but differs in its shorter prothorax, narrower form, more slender, much sparser scales of the elytra and more widely separated anterior coxtB. 6*74 Coleopterological Notices, IV. 8 Barinus albescens Lee. — Trans.

Beak three-fourths as long as the prothorax, very thick and arcuate, punctured toward base, the constriction strong, the ejQ bordered anteriorly by a line of three or four subrecumbent scales; antennae with the basal joint of the fuuicle as long as the next five, the club rather large, pale, nearly as long as the preceding six joints. Prothorax a little wider at apical third than at base, then very strongly convergent and deeply constricted to the apex, which is three-fourths as wide as the base ; sides nearly straight ; punctures fine and sparse. Scutellum very small, subglabrous. Elytra at base scarcel}^ noticeably wider than the prothorax, the sides straight and extremely feebh^ divergent thence to apical third, then broadly rounded, constricted at apical fifth, the apex obtuse ; humeri very feebly swollen ; striae fine ; in- tervals almost impunctate in the denuded lateral area. Femora bristling beneath with long setse. Prosternum longitudinally, nar- rowly sulcate, the coxse narrowly separated. Length 2.7 mm.; width 0.9 mm. Texas (Columbus). Cab. LeConte. Represented, as far as I know, by the unique type, taken by Mr. Schwarz. This species bears no resemblance, in any way, to linearis, with which it is accidentally united in the Henshaw Check-list, except in its gener- ally narrow subparallel form. 9 Barinus liiieiiris Lee. — Proe. Am. Phil. Soc., XV, p. 422 (Bari- lepton). Elongate, parallel, convex, black throughout, smooth but aluta- ceous in lustre, the vestiture white, consisting of moderately large. Coleopterological Notices, IV. 675 broad, triangular scales, almost evenly and quite sparsely distributed throughout but more denuded and sparse along the sides of the elytra, more broadly so toward base, and also in a small discal spot near the apex ; on the under surface the scales are dense on the met-episterna and toward the sides of the abdomen behind, else- where sparse but only absent on that part of the mesosternum bounding the middle coxal cavities externally. Head impunctate, but with a few extremely minute feeble punctures anteriorly; beak glabrous, punctate, very thick toward base, with some large scales bordering the eyes, much shorter than the prothorax ; basal joint of the antennal funicle scarcely as long as the next four together ; club moderate. Prothorax not quite as long as wide, the sides straight and parallel or very feebly divergent to apical two-fifths, then rounded and convergent, the constriction very broad and feeble ; apex not more than three-fifths as wide as the base; disk finely, rather unevenly but not very closely punctate, the scales almost uniformly distributed and sparse throughout; impunctate line dis- tinct, entire. Elytra just visibly wider than the prothorax and a little more than twice as long, parallel, narrowed in apical third, then obtusely rounded ; strife fine ; intervals flat, rather finely, unequally, confusedly and not very closely punctate. Prosternum impressed, the coxoe large, prominent, rather narrowly separated. Length 3.7 mm. ; width 1.25 mm. Florida (Sumter Co.). Cab. LeConte. Eepresented by the unique type, in which the last ventral segment has a rounded gla- brous polished and extremely deep median excavation. BARILEPTON. LeConte — Proc. Am. Phil. Soc, XV, p. 318. The species of Barilepton are probably the most slender of the Barini. The beak is short, thick, arcuate, strongly compressed, with the flanks crossed obliquely by the antennal scrobes, the latter beginning near the upper margin and slightly beyond the middle. The under surface of the head is frequently excavated transversely as in Barinus, and the basal joint of the funicle is elongate. The prosternum is broadly impressed and very narrowly separates the coxfe. One of the most remarkable characters of the genus is the structure of the tarsi, in which however it strongly resembles Bari- nus ; the four posterior tarsi are almost invariably longer than the tibiffi, and have the second and third joints dilated, the first being GTG Coleopterological Notices, IV. much smaller. There is but one tarsal claw, which is simple and moderately stout. The close relationship existing between Barilepton and Barinus affords another illustration, parallel to that of Eisonyx and Oomor- phidius previously mentioned, of the slight value to be attached, among some of the centrinide genera, to radical differences in the tarsal ungues, in comparison to the significance attending these modifications in the baride series. Our four species of Barilepton may be thus defined: — Elytra at base not wider than the base of the prothorax. Beak almost evenly arcuate 1 fllifoi'iue Beak strongly bent near the base ; body much smaller and still more slen- der; pronotal vestiture decidedly sparser 2 famelicilin Elytra at base wider than the contiguous base of the prothorax ; form a little stouter, the prothorax much less elongate. Prothorax constricted behind the apex; antennal club robust; basal joint of the hind tarsi longer, the second not quite as wide as the third and rather longer than wide, the third a little wider than long. 3 qiiadricolle Prothorax without trace of subapical constriction ; antennal club much less robust ; basal joint of the hind tarsi shorter and thicker, the second equal to the third and not longer than wide, the third scarcely as wide as long 4 falcigei* 1 Barilepton flliforiue Lee— Proc. Am. Phil. Soc, XV, p. 319. Cylindrical, convex, shining but very densely clothed with large broad pale scales, sparser on the pronotum except at the sides, pale fulvous on the elytra but white along the flanks and in a feel)ly defined streak attaining the base at each side of the scutellum. Head and basal parts of the beak punctured and squamose, the impression obsolete but with a small inconspicuous median fovea ; beak distinctly shorter than the prothorax, stout, arcuate, compressed toward base, smooth and almost impunctate, the antennae inserted near the middle, the basal joint of the funicle as long as the next five together, the second slightly longer than the third; club mode- rately stout, as long as the first funicular joint, the basal joint appa- rently large. Prothorax about as long as wide, sometimes feebly dilated at apical third, generally parallel, broadly rounded toward apex, the constriction obsolete; apex fully three-fourths as wide as the base; punctures deep, moderately coarse and not quite in mutual contact. Elytra about as wide as the prothorax and barely two and one-half times as long, the fine stride indicated by narrow Coleopterological Notices, IV. 617 partings of the very dense crust of scales. Prosternum feebly impressed, separating the coxae by one-fifth or sixth of their own width. Second tarsal joint almost as wide as the third and nearly as long as wide.

Hack, shining, the scales moderately large and broad, sparse and slender on the median parts of the pronotnm, dense throughout on the elytra, very sparse, minute and narrowly lineate throughout on the abdomen except the sides of the last three segments, which are densely squamose. Head finely, sparsely punctate and squamulose ; beak punctured and sparsely squamose toward base, elsewhere smooth and polished, compressed, thick, scarcely more than three- fourths as long as the prothorax, very strongly arcuate near the base, nearly straight in apical two-thirds, the antenna inserted at or slightly behind the middle, the basal joint of the funicle longer than the next four, the club robust, a little shorter than the preceding six joints together. Prothorax fully as long as wide, o/ten apparently a little longer, the sides parallel, nearly straight, feebly convergent and slightly rounded near the apex, the latter fully four-fifths as wide as the base, which is transverse, the median lobe almost obsolete ; subapical constriction completely wanting ; disk finely, rather sparsely and unevenly punctate. Scutellum very small, quadrate, glabrous, with one or two setae at each side. Elytra equal in width to the prothorax and about two and one-half times as long, parallel ; sides convergent in apical third, the apex obtusely rounded ; humeri not prominent ; disk with very fine striae, the intervals wide, flat, densely, confusedly squamose. Abdomen sparsely punctate. Prosternum transversely constricted behind the apex, broadly, distinctly impressed along the middle, separating the coxae very narrowly. Middle and posterior tarsi longer than the tibiae, the second joint not quite as wide as the third but much wider than the first. Length 2.1-2.65 mm. ; width 0.4-0.7 mm. Colorado (Greeley). Mr. H. F. Wickham. This very small species is closely allied io filiforme, but may be distinguished by its smaller size, more slender form, sparser and more slender scales especially on the pronotum and along the median parts of each elytron, and also by the form of the beak which is more abruptly and strongly arcuate near the base. Seven specimens. 3 Barileptou quadricolle Lee. — Proc. Am. Phil. Soc, XV, p. 423.

California (San Bernardino). The four hind tarsi are much longer than the tibite, the basal joint of the posterior obconical and distinctly shorter and narrower than the second, the latter large, as wide as long and fully as wide as the third, which is not transverse but narrowly deeply eniar- ginate, the fourth joint is rather short and very slender. The type is a male, having a long narrow impression near the base of the abdomen. ElJi\YSSOBlA n. n. EuchatesW LeConte — I'roc. Am. Phil. Soc, XV, p. 319. This genus was proposed by LeConte, unfortunately under a name which had been employed several times before in zoology, for one of the most remarkable curculionides thus far discovered. Its aberrant nature was in fact only partially known to its author, who makes no reference whatever to the mandibles. The general habitus of the body, abdominal structure and conformation of the mes-epimera, show that it is a normal member of the Barini, but its rostral and mandibular characters indicate that it should be widel}'- isolated, forming with Plocamus a group or subtribe. The beak is extremely slender, cylindrical and strongly arcuate, but becomes abruptly inflated and thickened behind the antennae, the under surface of the dilated portion having a narrow deep groove along the middle, which is gradually narrowed posteriorly and confluent at base with a deep transverse constriction, extend- ing upward at the sides just in front of the eyes, becoming gradu- ally attenuated and extinct and not attaining the upper surface. This longitudinal groove is but a remnant of the usual channel formed by the confluent scrobes, and is far too narrow to receive the antennal scape, the latter being free. The antennte are com- pletely inferior in insertion and are situated between basal third and fourth in both sexes, the scape rather thick, short and extend- ing to the under surface of the head between the eyes, the latter being normal and widely separated beneath. The mandibles are very short and thick, compressed, bent upward and move in a nearly vertical plane as in Balaninus, the condj'les being contiguous above and received in broad deep fissures at the 080 Coleopterological Notices, IV. sides of the buccal opening beneath ; the upturned apex is very coarsely and deeply notched. It can be readily seen that in this position, the condyles have the largest and most powerful muscular attachment permissible under the circumstances. The habits of this species, as well as Balaninus, necessitate a slender cylindrical boring tool, not at all enlarged at apex, and, if the condyles were horizontal in their plane of motion, they would, because of their slight lateral development, be very feeble in muscular action ; they have there- fore been gradually turned into a position as nearly vertical as pos- sible, simply to allow of a broader base for the attachment of the muscles. Mandibles of this kind are of course incapable of grasp- ing or pinching to any useful degree, and can be used only in cut- ting and scraping a passage for the advancing beak, and it does not follow at all that because the mandibles are similar in their action to those of Balaninus, that there is any special relationship between these genera. In point of fact the remaining structural characters of the body, including the form of the mandibles themselves, are so widely different in Balaninus and Eunyssobia, that there cannot be the least affinity between them, except in the method of using the beak as a boring instrument. The buccal fissure is very narrow and deep, being, at the anterior extremity, not more than one-fourth as wide as the rostrum, and the mentum is long and extremely slender; the remaining organs of the mouth appear to be atrophied or very feebly developed. The prosternum is broad, strongly, transversely constricted behind the apex but not otherwise modified, and separates the rather small coxie by nearly twice their own width. The legs are normal, the tarsi very slender, with the two basal joints elongate, feebly ob- conical and subequal, the third small, scarcely wider than the apex of the second, deeply emarginate, the fourth with its basal node, about as long as the first two together ; claws rather slender, arcu- ate, simple and divergent. Pygidium completely concealed. 1 Eiinyssoliia ecllidna Lee— Proc. Am. Phil. Soc, XV, p. 320 {Euduptes) . Oval, convex, very uneven, black, the antennae brown ; slender portion of the beak rufous; body extremely densely clothed through- out with a crust of large, closely adherent, scale-like plates, varie- gated white, brown and blackish in color and sparsely clothed with very long, stiff and erect spiniform bristles. Beak three-fourths Ooleopterological Notices, IV. G81 as long as the body in the female, sensibly shorter but otherwise entirely similar in the male, very slender, cylindrical, glabrous, shining, sparsely punctured in even series, evenly and stronglv arcuate from the antennae to the apex, but abruptly, strongly in- flated, thickened but straight in lateral profile, spinose and very densely covered with a rough crust of scales from that point to the base ; antennae slender, the scape short, the basal joint of the funicle subequal to the next two ; club moderate, oval, densely pubescent and without distinct sutures. Prothorax much wider than long, very strongly constricted and tubulate at apex, the base twice as wide as the apex, transverse but deeply sinuate at each side of the lobe, which is abrupt, prominent and rounded, its surface with a dorsal impression receiving the scutellum ; disk uneven, a large shallow impression on each side of the median line, behind the middle, especially obvious. Scutellum moderate, slightly tumid, oval, ogival behind, anteriorly prominent in the middle of the sinua- tion which receives the thoracic lobe and slipping partially over the surface of the latter. Elytra barely as long as wide, distinctly wider and two-thirds longer than the prothorax, the sides rapidly convergent and broadly evenly arcuate from base to apex, the latter very narrowly rounded, ogival, with a small sutural notch ; striae indicated only by very fine partings of the crust. Under surface and legs densely clothed with a squamose crust of cinereous scales and with short sparse erect and stiff setae. Length 2.6-3.2 mm.; width 1.3-1.6 mm. Ohio, Kentucky and Iowa, apparently not rare and said to depre- date upon the hickory; its habits are probably quite similar to those of Balaninus. It should be remarked that in some species of Cen- trinus, such as hospes, the beak is strongly inflated behind the an- tennae, especially in the female and probably from causes similar to those which have produced the inflation here ; but in Eunyssobia it does not appear to be at all sexual in character, and, in the species of Centrinus, the antennae are not inferior in insertion, although in hospes they are inserted very near the lower margin, the scrobes being broad and entirely inferior. PLOCAMIJS. LeCoiite— Proc. Am. Phil. Soc, XV, p. 320. The single small species forming the type of this genus is unmis- takably allied to Eunyssobia echidna, but differs in several peculi- G82 Coleopterological Notices, IV. avities of indubitable generic import. The principal of these are the shorter beak, which is gradually stout and conical near the base and not abruptly inflated, the channel beneath being broad, shallow, and serving as a partial shelter for the antennal scape, the absence of any trace of the transverse basal constriction, and the shorter second joint of the antennal funicle. The mandibles are entirely similar, but the trophi, and especially the maxillary palpi, seem to be larger and better developed, and the tarsi are shorter, particu- larly the second joint, which is but slightly longer and scarcely at all narrower than the third, the fourth being nearly as long as the first three together. 1 Plocanius Ilispiduliis Lee. — Proc. Am. Phil. Soc, XV, p. 320. Oljlong-oval, moderately convex, black, the beak rufous; antennre brown ; integuments densely clothed with large contiguous squarai- forni plates, variegated with white, brown, and piceous, a transverse spot of the latter color just behind the middle of the elytra especi- ally noticeable; under surface white; erect dorsal bristles very short and sparse. Beak but slightly longer than the head and prothorax, slender, arcuate, glabrous, linearly [)unctated and finely bicarinate beneath from the antennae to the apex, but rapidly and conically robust thence to the base, the basal portion densely clothed with large rough concave and squamiform plates; antennae inserted at basal fourth on the under surface, the scape short, attaining the head, the basal joint of the funicle slightly longer than the next two, second one-half longer than the third, seventh obconical, nearly as long as the fifth and sixth, club small, slender, not abrupt, oval, compressed, sparsely pubescent on the inner, densely on the outer side, devoid of sutures but with a small terminal button. Pro- thorax small, transverse, constricted and tubulate at apex, rather distinctly and densely punctate. Scutellum distinct, white, oval. Elytra abruptly much wider than the prothorax, more than twice as long as the latter, the sides subparallel toward base, gradually, broadly and obtusely rounded behind, with a minute and feeble sutural notch ; stride evident only as very fine partings of the crust. Presternum large, not in the least impressed, separating the coxae by not quite twice their own width and evenly, transversely con- stricted behind the apex. Length 1.9-2.2 mm. ; width 0.8-1.0 mm. Maryland. This species has been taken also by Mr. Ulke in the District of Columbia. Coleopterological Notices, IV. 683 Addenda. I. It is to be regretted that a number of species, described by the older writers, continue to remain unknown, and that it will be for- ever impossible to surely identify them, because of the neglect on the part of their several authors to record structural characters, which might enable us to form an opinion concerning their proper generic positions. These species are the following: — 1 Baridius anthracinus Boh. — Sch. Cure, III, p. 727. The depressed form may indicate a close relationship with Limnobaris, as before remarked (p. 554), but I do not know any species with decidedly trans- vei-se interstitial punctuation ; perhaps, like crevatus, the references to which are similar in the Munich Catalogue, it may be Mexican and not an inhabitant of the United States. 2 Baridius californicus Mots. — Bull. Mosc, 1845, II. p. 372. May possibly be the species subsequently described by LeConte under the name Centrimoi nastdiis. At any rate it might for the present be appropriately assigned to Limnobaris. 3 Baridius californicus Boh. — Eug. Res., Ins., 1859, p. 137. This is probably a species of Baris, allied to ritbripes, but having the beak longer and the elytral intervals smooth, or it may possibly be Onychoharis Aeriala. It is said to have been taken near San Francisco, 4 Baridius confertus Boh — Sch. Cure, III, p. 728. Described from Florida. It may be assigned at present to Onychobaris, although I have never seen a representative of that genus from the Atlantic regions. 5 Centrinus dilectus Harris — Trans. Hart, Soc. Nat. Hist., 1836, p. 79. The description enables us to assign this species to Centrinus without much doubt, and it may possibly be a large female example of one of the densely squamose variations of Centrinus saUbrosus. The locality is not recorded. 6 Centrinus pistor Germ. — Sch. Cure, III, p. 170, I can add notliing to the remarks made by LeConte (Proc. Am. Phil. Soc, XV, p. 433), except to suggest that this also may be the female of CenfrjHMs salehrosus, or of a species closely allied. ir. Baris scolopacea Germ. — This species, introduced from Europe, may be known by its elongate-oval, convex form and dense but uneven vestiture of white and brown scales, of which a subsutural white spot at the middle of eacli elytron is especially conspicuous. I have seen several specimens taken near Philadelphia. Scolopacea may be attached provisionally to Baris, but the long beak, separated from the head by a fine deep abrupt groove, and the Annals N. Y. Acad, Sci,, VI, Nov. 1892.— 45 684 Coleopterological Notices, IV. scaly vestiture, would necessitate its removal from the genus if studied with reference to the homologies of the American series of genera. The European species of Barini are more difficult to treat generically than our own. Some of them, such as schwarzenbergi, limbata, artemisiae, atronitens, carhonaria, chlorizans, and other similar forms, seem to be consistent with our conception of Baris, but there are many aberrant types, having the beak longer or sepa- rated from the head by a deep abrupt groove, or with the third tarsal joint undilated, the body covered with a waterproof coating of scales, or the tarsal claws subconnate at base, such as spoliafa, loricata, convexicollis, jncturata, sellata and nitens, which cannot be retained in Baris proper, and yet the structural differences do not appear to be great. In judging genera in this tribe, especially among the European representatives, much dependence will have to be placed upon that summation of minor characters known as " habitus", and, if with this difference of facies we can perceive some real structural peculiarity, a study of the European species in connection with our own seems to show that it will eventuall}^ have to be accepted as a generic criterion. There is no other way in which the old and new world species can be consistently arranged in homogeneous succession from a generic standpoint. III. The measurements of length throughout the present paper include the entire hody and head, but exclude the beak as usual. CALANDRID.E. Calandrin.e. CACTOPHAGUS Lee, This is a very w^ell defined and somewhat isolated genus, dis- tinguishable from Sphenophorus by the larger smoother body, cyl- indrical uncompressed beak and several other characters. It will include a number of species inhabiting northern Mexico and the regions adjacent. Our species are entirely black, but there are several before me from Mexico, in which each elytron has a sub- basal and subapical crimson fascia. The two species which are at once distinguishable among the Arizonian specimens in my cabinet, may be described as follows :— Coleopterological Notices, IV. 685 Body densely dull and velvety-black above, not in the least shining, the pro- notiiin not transversely grooved at base; elytral strise but just visibly coarser near the base, very finely, remotely punctate through(jut, the punctures only slightly less minute laterally. Length 22.0 mm. ; width 8.7 mm Talidlis Lee. Body less dull, alutaceous, not at all velvety, the head and beak polished ; punctures throughout larger and deeper ; pronotum with a deep entire transverse groove before the basal margin ; elytral striae fine but very deep, much coarser and more strongly punctate toward base, distinctly and less remotely punctate throughout, the punctures distinct by un- aided vision laterally and toward base ; elytra relatively less elongate. Length LS-O-IG..*) mm. ; widtli 7.0-8.0 mm. Arizona. Three specimens. subnitens n. sp. Siibnifens is not to be confonnded with the individual variation doscriljed by Dr. LeConte under the name procerus, the latter is dull, opaque and velvety-black like the typical forms of validus. The dull lustre in this genus is caused, not by granuliform re- ticulations, but by a beautifully regular system of extremely minute, subcontiguous but not in the least confluent punctures, which are deep and with the edges abrupt. In validus these minute punc- tures are finer and deeper than in siibnitens ; in the latter each of the fine sparse punctures of the intervals is surrounded by a pol- ished ring, caused by an obliteration of the minute ground-sculp- ture, while in validus these areolae do not exist. CALAXDRA Clairv. It is possible that this genus may have originated in the hypo- thetical continent, represented at present by a few islands extending from Ceylon to Madagascar ; several species are, however, now endemic in the East Indies and one or two perhaps on the west coast of South America. From these regions a number of species have been distributed throughout the world in various kinds of grain. It is quite impossible, therefore, to be sure of the native country of any unfamiliar forms which may occur among us, and, perhaps because of this uncertainty, the genus as a whole has been neglected of late by systematic writers. In arranging the numerous examples in my cabinet I find four widely distinct species and two subspecies. The true species, one of which it is impossible to identify from published descrii)tions, may be characterized as follows : — G8fi Coleopterological Notices, IV. Elytra with impressed and feebly punctate sulci, the intervals smooth and alternately wider and more elevated especially toward base ; pronotura with coarse sparse and elongate punctures graiiai'ia Elytra with contiguous double series of coarse deep punctures, the double series separated by narrow uniseriately punctate intervals. Pronotal punctures fine even and distinctly separated, the surface smooth and unusually convex linearis Pronotal punctures rather coarse, deep, very dense especially toward the sides, rounded and not elongate, the surface rather depressed on the disk. oryzae Pronotal sculpture extremely coarse deep and dense, consisting of long sinuous anastomosing and obscurely punctate rugse, with a narrow but entire subcariniform median line ; elytral sculpture exceedingly deep and dense Mlgicollis C. granaria Linn. — Syst. Nat., Ed. X, p. 378 ; remotepunctata Gyll. : Sch. Cure, IV, p. 979. The differences given by Gyllenbal to distinguish 7'emofepKnctafa are apparently not sufficient, for, color being of little or no value, the only character given to distinguish it is the slightly greater distinctness of the strial punctures toward the suture and of the punctured series of the sutural interval. Length 3.3-4.0 nnn. ; width 1.1-1.3 mm. Distributed throughout the United States. C. linearis Hbst.— Kaf., VII, p. .5, t. 100, f. 1. Described from the West Indies but occurring at times in the Atlantic States. It may always be known by the fine even punc- tuation of the pronotum. Length 3..3-3.8 mm. ; width 1.1-1.15 mm. Probably a native of India, from which region a variety is noted in the Munich Catalogue. C. oryzae Linn. — Amoen. Ac, VI, 1763, p. 395. The typical form of this cosmopolitan species is perhaps the smallest member of the genus. It somewhat resembles the two previous species in outline, but is very densely punctured on the pronotum, the punctures much coarser than in linearis and not elongated as in granaria. A series of eleven specimens of what may be regarded as the typical form, give the length 2.1-2.8 mm. and width 0.75-1.0 mm. Var. zea-mais Mots.— Etud. Ent., IV, 1855, p. 77. Similar in every appreciable detail of structure to oryzae, but always larger and especially stouter. A series of eight specimens Coleopterological Notices, IV. C87 from Texas (Austin) and Florida give the following dimensions. Length 3.2-3.4 mm. ; width 1.1-1.25 mm. Another variety is represented before me by two specimens from Guerrero, Mexico, which are of about the same size as zea-mais, but more coarsely and densely punctate, and more opaque, with the elytral punctures more quadrate. C. rugicollis n. sp. — Oval, moderately stout, rather flattened above, dull, very sparsely clothed with short erect yellowish setse, forming single series on the alternate elytral intervals. Head deeply but not coarsely, rather sparsely punctate, with a large deep fovea between the eyes ; beak in the female slender, feebly arcuate, smooth, minutely sparsely and sub- seriately punctate, fully as long as the prothorax, abruptly and angularly dilated, duller and coarsely, seriately punctate near the base ; antennse in- serted at basal sixth, slender, the second funicular joint obconical and one- half longer than the third. Prothorax barely as long as wide, the sides rather strongly convergent from near the base, rounded at base, deeply, tubularly constricted at apex, the latter fully one-half as wide as the base ; disk deeply, rugosely punctate. Scutellum dull, impressed. Elijtra at the humeri exactly equal in width to the disk of the prothorax, two-fifths longer, the sides strongly convergent throughout and nearly straight ; apex conjointly rather narrowly rounded ; disk with contiguous series of very coarse, quadrate, closely crowded punctures, alternately separated by narrow flat intervals, each of which is coarsely, uniseriately punctate, the punctures oval and almost contiguous. Pygidiuin and under surface coarsely deeply and densely punctate. Length 4.0 mm. ; width 1.5 mm. Florida. A single specimen, taken b}- Mr. F. Kinzel in the southern part of the State and presented to me by Mr. W. Jiiiich. This species is undoubtedly allied to the African rugonirf; Thunb,, but differs according to the description of ScLo.iherr, in its much shorter, non- canaliculate prothorax, and its more strongly and closely punctate abdomen. Riigicollis is brownish-black in color, the elytra each clouded feebly with rufous along the middle. The base of the pro- thorax is transverse and perfectly straight. In riu/ot^ns the pro- thorax is said to be one-half longer than its basal width. Rhinin^. YUCCABORUS Lee. This singular genus is unmistakably allied to Rhina, being in fact nearly identical in rostral structure, but differs in many impor- tant features, among which may be mentioned the widely separated 688 Coleopterological Notices, IV. eyes, much more abbreviated, dilated and semi-corneous antennal club, deflexed beak, short legs, and smaller size of the body. The three species before me may be easily separated as follows : — Piceoiis-brown, the punctuation of the upper surface finer and more remote. Body narrowly cylindrical, the elytra more tlian twice as long as wide ; punctures of the elytral series becoming very fine and feeble in apical half, the fifth and sixth series coalescent at base; humeri tumid and prominent frontalis Body much more robust, the elytra not quite twice as long as wide ; punc- tures of the elytral series deep throughout, although small in apical half as usual ; fifth and sixth series widely separated at base ; humeri not tumid sliarpi Black, much larger, coarsely and deeply sculptured ; legs and tarsi stouter. grossus Y. frontalis Lee. — Trans.

The prothorax is very nearly as long as wide, the sides broadly, evenly arcuate, the apex finely and deeply constricted, three-fourths as wide as the base, the latter broadly evenly and just visibly arcuate. Elytra but slightly wider than the prothorax and much more than twice as long, strongly alutaeeous especially be- hind, the series feebly impressed, the intervals toward base three to four times as wide as the strial punctures, sparsely punctured.

Head convex, polished, strongly but remotely punctate ; eyes very remote above, contiguous beneath ; beak in the male straight, wider than thick, parallel, coarsely deeply and rugosely punctate, feebly dilated at the antennie, barely three-fourths as long as tlie prothorax ; antennfe inserted just beyond the middle, the scape thick, attaining the eye, second funicular joint longer than the first and as long as the next two, club oval, compressed, as long as the four preceding joints, the polished corneous part extending, on the flat side, to apical third. Prothorax about as long as wide ; sides evenly, broadly arcuate ; apex finely constricted, three-fourths as wide as the base ; punctures coarse, perforate, remote, close on the flanks. Scutellum small, polished. Elytra one-third wider than the prothorax, more than twice as long, the punctured series strongly impressed toward base ; interstitial punctures remote, confused but forming nearly even single series on the narrower intervals. Length 9.7 mm. ; width 3.7 mm. Coleopterological Notices, IV. 689 Mexico (Guerrero). Mr. Baron, Allied to frontalis but disting'uishable by its stouter form, more polished integuments, much less prominent humeri and several other characters. I take great pleasure in dedicating this species to Dr. D. Sharp. Y. groSSUS n. sp. — Oblong, subcylindrical, broadly feebly convex above, deep black, polished, the elytra dull.

Piothorax about as long as wide, the apex con- stricted, two-thirds as wide as the base ; sides broadly arcuate ; disk evenly convex, very coarsely perforato-punctate, the punctures well separated above, coalescent on the flanks. Elytra one-third wider than the prothorax and more than twice as long, not quite twice as long as wide ; strial punctures deep, coarse, contiguous, continuing large and distinct to the apex ; intervals toward base two to three times as wide as the striae, coarsely, unevenly, sparsely punctate, anterior tibiae broadly, feebly arcuate toward apex, having an in- ternal series of small denticles.

M. repeus n. sp. — Elongate-ovoidal, convex, dull, black and subgla- brous, each large fovea, however, with a small fulvous seta; there are also a few clusters of such setse on the more tumid portions of the elytral intervals. Head glabrous; beak not quite as long as the prothorax, dull, with coarse sliallow punctures, sublinearly arranged but becoming finer and irregular to- ward apex.

I took the type specimen in some loose mossy turf, covering- the gravelly slopes of a shallow ravine near the town of Areata ; its sex is not apparent. This is one of the largest cossouides in our fauna excluding the genus Cossonus. HIMATIUM Woll. There is some doubt concerning the actual identity of Wollas- ton's genus with the species assigned to it by LeCoute. Accord- ing to the description, however, it must be very closely allied to Coleopterological Notices, IV. 691 our representatives, to such a degree indeed that these could not be advantageously separated without inspecting the original type. As represented by nigrituhim, the genus has the body rather de- pressed above, feebly cuneiform, with the head short and almost en- tirely enclosed within a snbtubulate extension of the prothorax, the eyes small, flat, coarsely faceted and in great part inferior, not visible from above but widely separated beneath. Beak short but slender, feebly arcuate, parallel, inserted at an angle with the surface of the front, so that it is distinctly separated from and very much nar- row'er than the head. Antennae inserted quite distinctly behind the middle, the scrobes nearly horizontal, not attaining but directed upon the eye ; scape short, clavate ; funicle slender, 7-jointed, the basal joint rather longer than the next two; second to seventh feebly increasing in thickness, equal in length, subquadrate; club as long as the preceding four joints, narrowly fusiform, polished, sparsely setose, not annulate. Scutellum distinct. Prosternum flat ; anterior coxte remote, separated by fully their own width ; intermediate one-half more widely separated. Metasternum long. Legs short, slender ; tibiae without internal spur, the uncus well developed ; tarsi short, the third joint feebly dilated, the fourth about as long as the preceding three combined. The three species, which it is necessary to include at present within the genus, may be recognized as follows: — Prothorax truncate laterally at apex, remote from the eyes. Body parallel, ferruginous, densely but coarsely pubescent, the pronotum coarsely, subconfluently punctate, the elytral series coarse and appi-oxi- mate errans Body subcuneate, more convex, black, much less pubescent, the pronotal punctures much smaller, distinctly defined ; elytral series not impressed, the intervals wide Ilij^l'itulum Prothorax partially concealing the eyes at the sides ; beak not distinctly sepa- rated from the head by a transversa impression COllicuilt H. conicani must certainly constitute a genus distinct from that including errans, if the characters given by LeConte are correct (Trans. Am. Ent. Soc, VIII, p. 218), and the probabilities are that each of these species will ultimately become the type of a dis- tinct genus. H. Iligritllllini n. sp. — Black, the elytra somewhat shining, legs, an- tenn;e and apical parts of the prothorax piceous-brown, vestiture very sparse, consisting of erect setiform scales, especially visible on the beak and toward 692 Goleopterological Notices, IV. the eljtral apex. Head smooth, vaguely sculptured, polished ; beak three- fourths as long as the prothorax, opaque, finely but deeply, rugosely and very densely sculptured. Prothorax conical, a little longer than wide, con- stricted behind the apex, the apical tabulation feebly inflated, receiving the head ; apex three-fourths as wide as the base ; punctures moderately coarse, deep, rounded but subcontiguous, without median line. Elijtra slightly wider behind the middle than at base, nearly two-thirds wider than the prothorax and more than twice as long; sides feebly arcuate, abruptly convergent and sinuate near the apex ; humeri broadly exposed but rather obtuse ; disk with unimpressed series of moderately l§rge deep oblong and almost contiguous punctures ; intervals flat, a little wider than the serial punctures, feebly rugose but shining. Under surface densely deeply and rather coarsely punc- tate. Length 1.75 mm. ; width 0.6 mm. Florida. A single specimen without more precise indication of locality. ALLOJUfiltlUS Lee. In this genus the beak is rather thin or but moderately stout, nearly straight, parallel, not conspicuously separated from the front, the eyes moderate in size, rather convex, not very finely faceted and situated at the sides of the head, the antennal scrobes deep, sublinear, directed feebly downward to the lower limit of the eye, the funicle t-jointed, with the basal joint larger, the second obconieal and distinctly longer than the third. Our two species differ greatly in structure and should perhaps be assigned to sepa- rate subgenera ; they may be defined as follows : — Beak thinner, a little more than one-half as long as the prothorax ; anterior coxae larger, separated by their own width ; elytra deeply striate, the sulci coarsely punctate, the sutural sulcus much less distinctly so. dllbillS Horn Beak shorter and stouter, scarcely one-half as long as the prothorax ; pronotal punctures smaller and closer ; elytra feebly sulcate and much less coarsely punctate, the punctures of the sutural stria as distinct as the others ; an- terior coxse much smaller and more remote, separated by nearly twice their own width. Head polished, almost impunctate, separated from the beak by a feeble transverse impression, the beak throughout coarsely deeply and subrugosely punctate. Prothorax about as long as wide, snbconical, feebly depressed above, slightly constricted behind the apex, the latter barely two-thirds as wide as the base. Scutellum distinct. Elytra a little wider than the prothorax and about twice as long, par- allel, the sides convergent and nearly straight in apical third, the apex narrowly I'ounded. Abdomen deeply but not very densely and somewhat unevenly punctate. Length 1.9 mm. ; width 0.65 mm. Texas CColumbus and Austin) politlis n. sp. Coleopferological Notices, IV. 693 Politus is slightly smaller, relatively broader and more depressed than dubius, and may be known at once by the shorter beak, finer, more even sculpture, paler color and smaller, much more remote anterior coxae. STENA^fCYLUS n. gen. The principal characters may be expressed as follows: — Body elongate, slender, convex, the scutellum distinct, the metasternnin elongate and the anterior coxae widely separated. Head rather elongate, coni- cal ; beak short, broad, parallel, not in the least constricted or transvei'sely impressed at base. Antennae inserted behind the middle, the scrobes deep, beginning beyond the middle, rapidly descending to the lower margin of the eye ; scape moderate in length ; funicle 7-jointed, the basal joint rather stout, as long as the next two ; second to seventh rather short, subequal, feebly in- creasing in width, just visibly obconical ; club moderate, oval, densely but coarsely pubescent, with the basal joint constituting about one-half of the mass. Eyes not very large, situated at the sides of the head, very convex, prominent and coarsely faceted. Legs short ; tibise rather slender, with a small internal spur at apex, the external uncus well developed ; tarsi rather stout, the third joint feebly dilated, fourth slender, arcuate, not quite as long as the three preceding together. This genus is allied to Macrancylus, but differs in its rather stouter, more elliptic body and radically in its oblique and not hori- zontal scrobes, also in its more prominent and coarsely faceted eyes, and parallel beak; in Macrancylus the beak is conical in form. From Rhyncolus it may be known at once by its more widely separated coxse and coarsely faceted eyes, as well as its more slender bodily form. S. COlomboi n. sp. — Elongate, narrowly oval, cylindrically convex, glabrous, polished and pale rufo-piceous throughout. Head and beak con- tinuous, transversely convex, finely but strongly, not very densely punctate, the eyes situated at a great distance from the prothorax ; beak scarcely as long as the head and two-fifths as long as the prothorax, straight. Prothorax a little longer than wide, broadly, very feebly constricted near the apex, the sides feebly arcuate ; apex slightly arcuate, three-fourths as wide as the base ; punctures rather fine but strong, uneven but separated by about their own widths without trace of median line. Scutellum small, oval. Elytra dis- tinctly wider than the prothorax and more than twice as long, twice as long as wide, the sides parallel and straight to apical third, then convergent and sinuate, the apex narrowly obtuse ; humeri right ; strife coarsely feebly im- pressed, coarsely punctate ; intervals narrow, finely, uniseriately punctate. Under surface coarsely but not very densely punctate. Length 2.2-2.4 mm. ; widthO.(imm. %S.OsA^Mr 694 Coleopterological Notices, IV. Florida (Biscayne Bay and Cape Jupiter). Mr. Schvvarz. I have dedicated this species to the memory of the distinguished navigator Cristoforo Colombo. CARPHOIVOTL'S n. geu. A single species, boreal in habitat and partially pubescent, pos- sesses several peculiarities of structure which appear to prevent its assignment to any of the described genera. Body moderately stout, somewhat depressed above, the elytra parallel, much wider than the prothorax ; soutellum distinct, flat, ogival. Head short, the beak straight, moderately short, parallel, not separated from the head by a transverse impression. Antennae inserted a little beyond the middle, the scrobes deep, obliquely descending beneath the eye ; scape moderate ; funicle 7-jointed, the basal joint stout, as long as the next two ; second to seventh equal in length, but slightly wider than long, gradually a little thicker ; club abrupt, moderate in size, the basal joint large, polished, sparsely setose. Eyes on the sides of the head at their own length from the prothorax, not very finely faceted, somewhat convex and prominent, transversely oval. Prosternum separating the large anterior coxae by one-half of their own width ; interme- diate coxse rather more than twice as widely separated as the anterior. Meta- sternum long. Legs stout ; tibiae parallel, the external uncus well developed but without trace of internal spur at aj^ex ; tarsi rather stout, the third joint distinctly dilated and bilobed. This genus is somewhat allied to Stenancylus, but differs in its broader form, relatively narrower prothora.x, less prominent, more finely faceted eN'es situated much nearer to the anterior margin of the prothorax, shorter head, longer beak with the antennae inserted beyond the middle, relatively less widely separated anterior coxa?, absence of internal tibial spur, and in the hairy vestiture. C. testaceilS n. sp. — Oblong-oval, feebly depressed above, pale rufo tes- taceous throughout, smooth and polished, the upper surface with short coarse and very sparse, subrecumbent pubescence, becoming erect toward the elytral apices and somewhat bristling on the beak. Head and beak minutely but strongly, not very densely punctate, the beak twice as long as the head and three-fifths as long as the prothorax, viewed anteriorly nearly twice as long as wide. Prothorax about as long as wide, feebly constricted near tlie apex ; sides subparallel and very slightly arcuate ; apex broadly, feebly arcuate and but slightly narrower than the base ; punctures rather fine but deep, perfo- rate, somewhat sparse ; median line obsolete. Elytra one-half wider than the prothorax and two and one-half times as long, twice as long as wide, parallel and straight at the sides, obtusely ogival in scarcely more than apical fourth ; humeri right, blunt ; disk with entirely unimpressed series of large oblong- Coleopterological Notices, IV. 695 elongate snbbilobed punctures ; intervals flat, but slightly wider than tlie serial punctures, each with a single uneven series of minute, feeble punc- tures. Under surface throughout rather finely but deeply and somewhat densely punctate. Length 2.8 mm. ; width 0.9 ram. Minnesota. Easily distinguishable from any species of Rhyncolus by its de- pressed form, narrow beak and prothorax, and pubescent surface. APOTREPIJS n. gen. A single species again constitutes a genus which is without any close ally in our fauna. Body stout, subcylindrical, moderately convex, the elytra wider than the prothorax. the scutellum distinct ; upper surface setose. Head short, broad, couo-globose, not conspicuously separated from the beak. Beak rather short, robust, parallel toward base but dilated toward apex. Eyes situated at the sides, partially on the beak, distant from the prothorax, feebly convex and rather prominent, somewhat coarsely faceted. Antennae inserted at the middle, the scrobes deep, linear, obliquely descending to the lo^rer limit of the eyes ; scape robust ; funicle long, 7-jointed, the two basal joints equal, each longer than wide and longer than three to seven, which are subequal in length, gradually thicker, obconical, submoniliform, the articulations strongly marked ; club oval, densely but coarsely pubescent, abrupt, fully as long as the preceding four joints, not annulate. Anterior coxae small, re- mote, separated by fully their own width ; intermediate still more widely separated. Metasternum long. Legs rather long but somewhat stout, the tibiae parallel, with a small internal spur and well-deveh)ped external uncus at apex ; tarsi rather long, the basal joint nearly as long as the next two, third feebly dilated, fourth but slightly longer than the preceding two com- bined. Apotrepus is related to CaiilojJiihis latinasiis perhaps more closely than to any other North American species, resembling it in general form of the body, but differing greatly in its shorter beak dilated near the apex, in its smaller eyes, longer second funic- ular joint, and in the sparse bristling and setiform vestiture. A. deiisicollis n. sp. — Black, the antennae and legs feebly rufescent, rather shining, the s*^tae short, stiff, erect, forming an uneven single line on each elytral interval. Head very short, finely, sparsely punctate, the beak nearly straight, densely, subrugosely punctate, more than twice as long as the head and separated therefiom only by a very broad transverse impres- sion, from the anterior margin of the eyes to the apex one-half as long as the prothorax, not twice as long as wide viewed anteriorly. Prothorax about as long as wide, broadly, strongly constricted behind the apex, the sides feebly 69G Coleopterological Notices, IV. convergent and distinctly arcuate ; apex tliree- fourths as wide as the base; disk rather coarsely deeply and extremely densely punctate, the punctures polygonally crowded, without median line. Elt/tra one-tliird to two-fifths wider than the prothorax and rather more than twice as long, two-thirds longer than wide ; sides parallel and nearly straight in basal two-thirds, then gradually rounded convergent and sinuate to the apex; humeri right, narrowly rounded ; strife coarse, feebly impressed, coarsely deeply and ap- proximately punctate, the intervals about as wide as the strial punctures, scarcely perceptibly punctate. Under surface rather coarsely, densely punc- tate, the abdomen more finely and sparsely so. Length 2.S— 3.0 mm. ; width 1.0 mm. Arizona. Two specimens. PSEUDOPE^TARTHRIJM Woll. This genus was founded by Wollaston upon a small species from Mexico, resembling Phloeophagus, and with the anterior coxa3 ap- proximate as in that genus, but having the antenna! funicle 5-jointed. It is distinguished from Pentarlhrum by its much less distant an- terior coxae and more abbreviated cylindrical form. 1 now assign to it two other species, having the beak very short, thick but parallel, not constricted at base, though sometimes separated from the liead by a l)road feeble transverse impression. Eyes moderately devel- oped, feebly convex, finely faceted, situated at the upper part of the sides and conspicuous from above; scrobes horizontal, deep, ending at quite an appreciable distance in front of the eye and there flexed abruptly downward. Antennae inserted at basal third, thick, the basal joint of the funiele large, two to five transverse, parallel, sub- equal, closely coarctate, the club continuous with the funicle, and, together with joints two to five, strongly compressed. Scutellum distinct. Metasternum rather long. Anterior coxae closely approxi- mate. Legs short, robust, the tarsi stout with the third joint but slightly wider than the second, the fourth not as long as the re- mainder, arcuate and ver}^ slender. Pseudopentarthrum differs from Pentarthrinus in its shorter, more parallel form, relatively larger prothorax, in the greater distance between the antennal scrobes and the e}e, in the more compact and compressed antennae, with the club not abrupt, and in its stouter legs. The species may be separated by the following characters: — Beak not separated from the head by a pronounced transverse impression ; larger species, the pronotum highly polished roblistlliu Coleopterological Notices, IV. 697 Beak separated by a broad transverse impression ; head and basal parts of the beak finely, remotely punctate, the remainder of the beak densely so ; pronothm dull simplex P. rolllistum n. sp. — Robust, cylindrical, the elytra perfectly parallel and a little wider than the prothorax, polished, black and glabrous through- out. Head rather finely but deeply, not densely punctate ; beak thick, finely punctate, not separated from the head by a transverse impression, two-fifths as long as the prothorax ; scrobes not extending to the eye, rectangular ; antennae inserted at basal third, first funicular joint large, wider than long, rather longer than the next two, second concealed partly within the apex of the first, apparently shorter than the third, two to five coarctate, forming a thick com- pressed mass, the club scarcely at all wider or thicker and forming nearly a prolongation of the funicle. Prothorax about as long as wide, broadly rounded on the sides, constricted behind the apex, the latter three-fourths as wide as the base ; punctures coarse, deep, perforate, separated by about one-half of their own diameters, with a polished impunctate central spot. Scutellum rounded, slightly tumid. Eli/tra one-half longer than wide ; striae deeply impressed, coarsely deeply and closely punctate ; intervals two to three times as wide as the strial punctures, convex. Under surface coarsely, closely punc- tate, the abdomen more sparsely so, and more finely, except at base. Length 3.7 mm. ; width 1.3 mm. Texas (Austin). The single specimen is of undetermined sex. P. simplex n. sp. — Cylindrical, moderately stout, black, glabrous, the pronotum subalutaceous. Head very finely, sparsely punctate ; beak finely, closely punctate except toward base, separated from the head by a rather deep wide transverse impression, which is very sparsely punctate and minutely, obsoletely foveolate, thick, parallel, as long as the head, not one-half as long as the prothorax ; scrobes deep, rectangular, not attaining the eye by a very noticeable distance; antenna inserted near basal third, nearly as in robusfum, but witli the joints much less transverse. Protliorax nearly as long as wide, feebly constricted behind the apex, the latter broadly arcuate and nearly four- fifths as wide as the base; sides feebly arcuate ; punctures coarse, deep, sepa- rated by much less than their own widths, without median impunctate area. Elytra parallel, barely three-fifths longer than wide, nearly twice as long as the prothorax and slightly wider ; striae deeply impressed, coarsely, deeply but not very closely punctate ; intervals convex, finely, sparsely, subseriately punctate, twice as wide as the strial punctures. Under surface not coarsely but strongly, rather- sparsely i^unctate throughout. Length 2.5 mm. ; width 0.95 mm. Nebraska. Allied to rohustum but differing- in its smaller size, dull and not polished pronotum, relatively longer elytra with narrower int
