The fact that two entire families of North American Coleop- tera, although treated monographically in the present work, are composed principally of species whose names now appear for the first time in the annals of scientific literature, must be regretfully regarded as proving the comparatively slight amount of interest evinced in this country for the systematic study of entomology. The study of nature in any sphere is ennobling and broaden- ing to the mind, whether it concerns elementary matter or the phj'sical forces which control the universe, the infusoria or the mammals, the bacteria or those great trees which excite the ad- miration of the most apathetic of us ; but, as we human beings are primarily and essentially a social animal, it is evident that in a general sense the opinion of the people at large must have some weight in fashioning the tastes and predilections, even of those in whom the thirst for disinterested research is especially devel- oped. We can account in this wa}" for the exceedingly small pro- portion of scientific men who regard the study of morphological entomology as worthy of very serious consideration, although it can scarcely be disputed that in the Insecta occur the most won- derful structures to be found in the entire domain of nature, the most singular adaptations, and the most prolific sources of data to be ultimately utilized in attacking some of the apparently in- scrutable problems of biological evolution. Perhaps the day may arrive some centuries hence, when the world shall have become more widely and more homogeneously educated, when systematic workers in the field of entomology can count themselves among the candidates for honors and dis- tinctions, similar to those now bestowed by popular favor upon him who discovers out in space a tiny point revolving about a dash of light almost equally minute, or who, by mathematical AxxALS N. Y. Acad. Sci., VIIL, July, 189.5.— 31. 436 Coleopteroloijical Xoticcs, VI. logic deduces the laws of planetary motion, or who. by patient and careful weighing discovers a hitherto unknown constituent of our atmosphere. These fields of scientific enijuiry are all parts of one grand cosmos, and I cannot conceive one of tiiem to be more soul-inspiring than another; they are all equally wonderful, equally beautiful, and equally beyond the ken of Unite intellect. XoKKOLK, Va., May l^*, 1H95. STAPIIYLINID.E. C'OXOSOMA Kraatz. This genus is represented in America l)y numerous species, which, because of their comparatively constant and monotonous facies, have gained the reputation of being a difficult lot to deal with systematicalh- ; but this is by no means the case in reality. There are several sclerites which are sutiiciently diversified to afford most satisfactory taxonomic elements, and in fact the species can be separated into two almost equal divisions, based upon radically different types of epijileural structure Avhich can be recognized upon mere cursory examination. The extent of development of the long erect tactile seti\} of the al)domen, an- tennal structure, sculpture of the elytra and ventral characters of the male can also be employed advantageously in classification, as these all difi!^er in a marked and sufficiently constant degree among the various species ; the difference in elytral sculpture be- tween lowxi, bipustulata and parvula, for example, is very pro- nounced. In some cases I have resorted to peculiarities of color- ation for the principal difl^'erential character of the species. In the following table I have been compelled to add a number of new species to those already known, and to correct some very inaccurate and misleading synonymv which has been allowed to stand in our recent lists : — I. Epipleuni' broader, siililioiizontal, iniliesceiit, impressed toward hase, birt witli the outer inarjiin only descendinu slightly below the inner. Pronotuni abruptly pale in color in bas;il half, the elytra pale but blackish laterally and toward a]>ex 1- kiioxi Pronotuni unicolorous or only feebly and sutYusedly i>ale t(n\ard l)ase.

Whenever possible the descriptions which follow are drawn from the male. The measurements of length refer to the head and body as far as the extremit}^ of the elytra, the abdomen being wholly excluded. 1. C. knoxi Lee. — Proc. Acad. Nat. Sci., Phila., 1866, p. 374; Horn: Trans. Am. Eiit. Soc, VI., 1(^77, p. 110. Moderateh' broad, testaceous, the head and apical half of the pi'onotum, elytra externally and toward apex and abdomen in about apical half, black ; antennre blackish but testaceous toward apex and base. Head nearly one-half as wide as the prothorax, minutel}' punctulate, extremely minutely and feebly substrigilate, the antennae long, feebly incrassate, the tenth joint in the male but slightly longer than wide, the eleventh one-half longer than wide and acutely and s^'mmetrically pointed. Prothorax three-fifths wider than long, the apex about three-fifths as wide as the base, minutely, very closely and rather distinctl}" punctulate, the sur- face extremely minutely and transversely substrigilate. Elytra nearly as long as wide, only slightly narrowed from the base, with the sides evenly and feebly arcuate, slightly narrower than the prothorax, the external apical angles right and but little rounded ; apex very feebly, triangularly' emarginate; disk rather depressed and finely, excessivel}^ densely punctulate, extremely minutel}'^ and densely pubescent. Abdomen rapidly conical, the black seta? short and inconspicuous toward base. Length 2.25 mm.; width 1.25 mm. Pennsylvania to Wisconsin (Bayfield, Lake Superior). The male has a large triangular emargination at the apex of the sixth ventral segment, the angle of which is rather broadly rounded. In this distinct species the elytral sculpture and ves- titure are more minute and dense than in anj- other known to me. 2. C littorea Linn. — Faun. Suec, 852 ( Staphylinus ) ; Er. : Gen. Staph., p. 219 (Conurus); Horn: Tr. Am. Ent. Soc, VI., p. 109. Almost similar in form and size to knoxi, blackish throughout, the pronotum near the sides and a large somewhat obliquel}' oval spot at the middle of the base of each elj'tron testaceous ; apices of the ventral segments slightly pale. Length 2.4 mm.; width 1.35 mm. Europe and Massachusetts. The sixth ventral of the male has a very large triangular emargination nearl}- as in knoxi, but with Goleopterological Notices, VI. 439 the angle less rounded, and the elytral sculpture is extremely finely and closely imbricato-punctulate, almost as densel}' as in Inoxi. As in that species, the epipleurae are A-ery wide, nearh' flat, subhorizontal, densely pubescent and punctulate throughout and broadly, feebl}' impressed in the middle toward base. I am of the opinion that the few examples of this species thus far taken in the United States are mere sporadic importations. 3. C. opica Say — Traus. Am. Phil.

Oval, strongl}' convex, rather shining, blackish, the basal margin of the pronotum very narrowly and the base of the elytra broadl}-, rufescent; antennte infuscate, pale toward base, the eleventh joint yellowish ; legs pale. Head finely, sparsely punctulate, a little less than one-half as wide as the prothorax, the antenna? rather short and incrassate. the tenth joint distinctly transverse; last joint of the maxillary palpi slender, oblique and subulate, but nearly as long as the third. Prothorax two-thirds wider than long, the apex three-fifths as wide as the base, the basal angles but slightly prominent posteriorly and obtuseh" rounded ; disk not punctate except the minute scars left by fallen hairs, Scutellum large, tlie apex not at all rounded. Elytra not quite as long as wide, distinctly longer than the prothorax, evenly and moderatel}' nar- rowed from the base, the sculpture rather coarsely but feebly imbricate. Abdomen gradually and evenly tapering throughout the length, the erect bristles very short and inconspicuous except at tip. Length l.T mm.; width 1.05 mm. New York to Virginia and westward. The male has the sixth ventral broadly and triangularly emarginate at tip, the angle rounded. The epipleurst are horizontal, wide, coarsely pubescent throughout, and broadly and almost S3'mmetricall3' excavated toward base. 4. C imbricata Csy. — Cont. Descr. and Syst. Col. N. A., II., p. 143 (Conurus) ; jxtftfwen.s Horn nee Payk. : Traus. Am. Ent. Soc, VI., p. Ill; adeps Zimm. i. litt. Suboval, rather stout, very strongly convex, blackish through- out, the elytra generally more or less reddish ; legs rufous ; an- tenna? blackish except at apex and toward base ; punctures of the 440 Coleopterological Notices, VI. liead and i)ronotnm exceedingly minute and occupied almost en- tirely l)y the base of the hairs. Head one-half as wide as the pro- thorax, the antenn:\; rather long, gradually and evenly incrassate through the last six or seven joints, the penultimate slightly wider than long. Prothorax nearly- one-half wider than long, the basal angles rather al)ruptly prominent posteriorly-, right and not distinctly rounded. Elytra not quite as long as wide, somewhat distinctly longer than the prothorax, perceptibly narrowed from the base, with the sides ver3^ feebly but evenly arcuate, the disk strongly convex, perfectly even in coloration, somewhat coarsely and feebly imbricate and minutely, ver}^ densely pubes- cent. Abdomen quite evenly tapering from base to tip, the erect set{\3 short and inconspicuous except at the apex. Length 2.0- 2.25 mm.; width 1 15-1.3 mm. New York, New Jersey and Pennsylvania. The male has a feeble rounded median sinuation at the apex of the fifth ventral, the sixth having a deep rounded sinuation at the middle, about three times as wide as deep and with the external angles very broadly arcuate. The epipleurte are wide, punctulate and pu- bescent throughout, subhorizontal and l)roadly impressed in about basal half. This species is allied to the European pubescens, but is more convex, with more gradually incrassate antennaa, and differs also in coloration and decidedl}^ in sculpture. In puhescens Payk., of which I have before me a series carefully determined by Mr. Reitter, the elytra are smaller and more depressed, and are gener- ally rufous with the suture and flanks blackish ; the antenna? are much more rapidly and strongly incrassate through the outer five joints, and the penultimate joints are fully as long as wide; the sinuation of the fifth ventral is much wider and the rounded notch of the sixth narrower, not more than twice as wide as deep, with the external angles much less broadl3' rounded. In the European species the elytral sculpture is very much finer, denser and less distinctly imbricate, this being noticeable in all the numerous specimens compared, even under the low powers of the hand lens. The recentlv published lists of Coleoptera common to Europe and America have in several cases been carried much too far, and numerous instances occur, especiallj- in the Staphylinid.t?, where species closely allied by reason of community of descent have been regarded as identical ; in some cases the species which have Coleopterological Notices, VI. 441 been thought to be identical are not even particularly closel}' re- lated to each other. Tiiese mistakes principally refer to the fauna of eastern North America, the proportion of common forms of the west coast being much greater. In fact, if we omit the well known cosmopolitan species and those which have been sporadi- cally and locally introduced, the fauna of eastern America in- cludes but a very small actual number of species identical with their homologues of Europe, and there is no good reason why the term "'Nearctic" should not be employed for this region, in con- tradistinction to " Pahijarctic," which includes Europe, northern Asia and the west coast of North America. The large number of identical genera and closel}- allied species in the ISearctic and Palnearctic faunas shows plainly that they have a common origin, but there can be no doubt that the}' are now sufficiently differen- tiated to warrant a continuation of the distinctive appellations. 5. C liillllloides ii. sp. — Suhoval, strongly convex, mocleratelj' shining-, blackish throughout, the apices of the ventral segments slightly paler; legs pale testaceous, the posterior darker; autennie iufuscate toward the middle; pitbesceuce moderately fine, dense and decumbent, dark in color; j)unctures of the head and prouotum extremely fine, occupied by the base of the hairs ; those of the elytra not distinct. Head barely one-half as wide as the prothorax, the epistoma only moderately transverse; antennae extending slightly beyond the base of the prothorax, very stout and gradually incrassate, the penultimate joints rather strongly transverse. Prothornx rather elongate, not more than two-fifths wider than long, the .apex about three-fifths as wide as the base; sides evenly arcuate; basal angles moderatel}' and not very abruptly promi- nent posteriorly, slightly more than right and not much rounded. Scutellum large, triangular, slightly wider than long, with the sides very feebly arcuate and the apex scarcely at all blunt. Ehjtra not quite as long as wide and but slightly longer than the prothorax, the sides scarcely visibly convergent from base to apex and extremely feebly but evenly arcuate; apex very feebly angulato-emarginate; disk, rather coarsely imbricate, the imbrications feebly reticulate. Abdomen gradually tapering, the settle very short, sparse and in- conspicuous except at apex. Length 1.8 mm. ; width 1.2 mm. Iowa. Readily distinguishable from the preceding, which it strongly resembles in habitus, by the sexual characters of the male, the hfth ventral being completely unmodified and the sixth having a broad shallow apical sinuation, rounded at the bottom and four or five times as wide as deep ; it also dirters in its shorter antennjc, with the outer joints much more transverse. The epipleura' are nearl}- flat throughout, being fee'ily imi)ressed only near the base. Three specimens. 442 Coleopterolofiical Notices, VI. 6. C. velocipes n. sp. — Moderately stout, strongly convex, feel>ly shin- ing, blaokish, the basal niarjiins of the pronotuni and elytra unevenly and feebly suffused with a paler reddish tint: abdomen paler, red-brown through- out; legs and antenna- rufo-testaeeous, the latter paler and more yellowish toward base and at the eleventh joint; jjubescence very fine, dense and plum- beo-cinereous throughout, the punctures minute and scarcely visible. Head small, distinctly less than one-half as wide as the prothorax, the epistoma paler and with more distinct punctulation and reticulation; antenna; rather long, evenly and gradually incrassate througli the last six or seven joints; the ninth scarcely as long as wide, the tenth perceptibly wider than long, eleventh rather short, somewhat rapidly, obliquely and acutely pointed at apex. Prothorax nearly three-fifths wider than long, the apex but slightly more than one-half as Avide as the base, the sides evenly and strongly arcuate becoming l)arallel toward base, the basal angles gradually and only moderately promi- nent posteriorly and distinctly rounded. Eli/tra nearly one-fourth wider than long, not at all longer than the i)rothorax, the sides distinctly convergent but only very slightly arcuate from base to apex; disk convex, moderately finely imbricecome gradually nearly glabrous toward base. This species may be distinguished from imhricata l»y its shorter elytra and long black bristles toward the base of the abdomen. 7. C. castaiiea Horn — Trans. Am. Ent. Soc, VI.. p. Ill; iicntdiniulitm Fvl., i. litt. Rather stout, strongly convex, pale brownish-testaceous in color throughout, minutely and densely pubescent, the punctures scarcely visible. Length 1.7-1.9 mm.; width 1.1-1.3 mm. Coast regions of California from Humboldt to Los Angeles ; I obtained three specimens also at Lake Tahoe, which represent a slightly smaller and narrower variety. The male has a rounded Coleopterological Notices, VI. 443 sinuation at the apex of the sixth ventral, occupying about median third and about tliree times as wide as deep, and the apical mar- gin of the fifth segment is very feebly- sinuate in the middle. The epipleurffi are wide, pubescent throughout and broadly, feebly im- pressed toward base. A female specimen, taken near Monterej- Bay, is blackish throughout but does not seem to differ materiall3' otherwise. 8. C'. virgiiiiae ii. sp. — Stout, strongly convex, feebly sTiiniiig, the pu- bescence fine, very dense and pluniljeo-cinereous throughout, the punctures scarcely visible ; body pale brownish -testaceous in color, the legs concolorous; antennae brown, paler and diaphanous toward base, the eleventh joint also pale. Head small, scarcely two-fifths as wide as the prothorax, the antennse rather long, very evenly and gradually incrassate through the seven outer joints, the ninth slightly elongate, the tenth a little wider than long, eleventh scarcely one-half longer than Avide, almost symmetrically and rapidly pointed at apex. Frothorax one-half wider than long, strongly convex, the sides strongly and evenly arcnate, l^ecoming parallel toward base; the apex but slightly more than one-half as wide as the base, the basal angles gradually and strongly prominent posteriorly, right and slightly blunt. Elytra a little narrower and but very slightly longer than the prothorax, not quite as long as wide, the sides distinctly convergent and broadly arcuate from base to apex, the latter broadly and triangularly eniarginate; disk somewhat coarsely but feebly imbricato-punctulate. Abdomen gradually tapering from the base, the black seta? rather long and conspicuous even toward l^ase. Length 2.1 nun. ; width 1.4 mm. Virginia (Norfolk). In the male the sixth ventral has a triangular notch occupying about median third of the apex and about twice as wide as deep, with the angle scarcely at all rounded and the sides nearl^^ straight, and the fifth segment is feebly sinuate in the middle of the apical margin. The epipleura? are moderately wide, deeply hollowed in more than basal half, pubescent but becoming gradu- all}' glabrous near the base. A single specimen. 9. C niacer n. sp. — leather narrow, strongly convex, feebly shining, pale brownish-testaceous tln-oughout, the legs and antennte concolorous, the latter more flavate at apex and toward base as usual ; pubescence very dense, rather dark in color. Head nearly one-half as wide as the prothorax, the antenna) moderately long, evenly but rather rapidly incrassate through the five or six outer joints, the seventh elongate, the ninth and tenth somewhat wider than long, eleventh oval, stout and very obliquely i»inted at apex. Prothorax fully one-half wider than long, the apex two-thirds as wide as the 1)ase; sides evenly and strongly arcuate; basal angles gradually and strongly prominent posteriorly, right and ouly slightly hlnnt. Ehjira short and transverse, nearly 444 Coleojyterological Notices, VI. one-half wider tlian lon^o mm. North C-arolina (Asheville). The epipleur£fi are narrow, becoming obsolete before the rounded apical angles of the elytra and gradually vertical exter- nall}' toward base ; they are glabrous toward base but distinctlj' pubescent posteriorly. The epistomal suture is rather abruptly and posteriorly sinuate in the middle. The sixth ventral segment of the male has a large deep and triangular emargination. occupy- ing almost the entire apex, scarcely more than one-half wider than deep and with the angle slightly rounded. Numerous specimens are before me differing scarcely at all in size. 16. C. SUbtilis n. sp. — (Oblong-oval, strongly convex, feebly shining, pale castaneo -testaceous, with the elytra darker; legs, basal parts and apex of the antenna" paler; pubescence moderately short and dense, dark, the sculpture of the anterior parts very feel)le. Haul fully one-half as wide as the prothorax, the antenn;e about extending to the base of the latter, feebly iucrassate, with the tenth joint somewhat longer than wide; epistomal suture broadly and pos- teriorly sinuate almost throughout the width. Prothorax fully three-fifths wider than long, the apex three-fifths as wide as the base; sides evenly and strongly arcuate, becoming parallel at the basal angles, which are only moder- ately prominent posteriorly and distinctly rounded. Elytra one-fourth wider tlian long, the suture e(jual in length to the prothorax, the sides somewhat convergent and feebly arcuate from the base; external apical angles broadly rounded; disk rather closely imbricate, the imbrications freijuently crossed by a fine median line.

The male has a large deep and narrowly parabolic emargination occupying practically the entire apex of the sixth ventral seg- ment, and distinctly less than twice as wide as deep. The epipleu- rne are nearl}' as in debilis, but attain the rounded apical angles. This species is closely allied to dehihs. but may be distinguished Coleopterological Notices, VI. 449 by its narrower form and decidedl}' shorter elytra ; the first two joints of the antennte bear long black apical setie as in dehilis^ but the tip of the abdomen is paler and more acute in subtilis. 17. C. parvula Horn — Trans. Am. Eut. Boc, VI., p. 111. Rather narrowly suboval, convex, shining, castaneous, the an- tennae somewhat short and incrassate, with the penultimate joint transverse. Prothorax one-half wider than long, the sides arcu- ate, becoming parallel toward base, the basal angles obliquely and moderatel}^ prominent posteriorly and onl}^ slightly blunt ; disk ver3' coarsely but feebl}- reticulate. Elytra short, nearly one-half wider than long, narrowed behind, distinctly shorter than the prothorax, with the external angles at apex but little rounded and the disk very coarsely imbricate. Abdomen rapidly tapering, the long black seta? apparently obsolete toward base. Length 1.15 mm.; width 0.7 mm. North Carolina. This is the smallest species of the genus, and is very distinct from the two preceding in its coarse imbricate sculpture and very short elj'tra. The epipleurre are narrow, entire, becoming gradually and moderatelj^ deeply vertical externally to- ward base, and are slightl}- pubescent posteriorly. The male has a large triangular emargination at the apex of the sixth ventral, the notch more than twice as wide as deep and with the angle narrowly rounded. 18. C. scripta Horn— Trans. Am. Ent. Boc, YI., p. 112. Stout and suboval, very strongly convex, polished, rather sparsely clothed with coarse fulvo-cinereous hairs ; body pale brownish-testaceous in color throughout, the pronotum some- times slightl}' clouded and the elytra with a blackish nubilate de- sign. Length 1.3-1.5 mm.; width 0.95-1.0 mm. Rhode Island and New York. This species can be instantly recognized by the long black sette at the sides of the elytra, the setas being also more developed on the abdomen at the sides throughout than in any other member of the genus, and there are, besides, four series along the under surface of the abdomen. The epipleurje are narrow, entire, and only slightlv vertical externall}- toward base, but the3' differ from the forms prevailing in the preceding section of the genus in being com- pletely glabrous. The elytral punctures are rather sparse and distinct, feebly asperate, each with two short divergent lines, 450 Goleopterological Notices, VI. the sculpture not being imbricate but finely and subtransversely reticulate. The antennae are unusually short. The two speci- mens before me are females. TRO<;OPIII>;i nation of the prothorax ; antennal foveas extremely remotely separated, very near the eyes and represented from above by small emarj^i na- tions, the eyes in contact with the advanced apical angles of the prothorax ; antenna? not as long as the width of the head.

Eliitra ahowt as long as wide, evenly oval, the sides continuovis in curvature Avith those of the prothorax, the suture about three times as long as the latter and margined with a line feeble line which becomes obsolete near the base. Hind wings well developed. Length 1.0 mm.; width 0.6 mm. Florida (Dry Tortugas). Mr. H. F. Wickham. It is probable that this species will prove to be widely distrib- uted through the West Indies, and by no means confined to the small sand}^ islet near Key West. I have before me a single rather ill-conditioned specimen. MELYRID.E. After careful study of the considerable material in ni}- cabinet, I can see no cause to doubt the soundness of Motschulsky's opinion (Bull. Mosc, 1859, p. 388) that the melyrides should con- stitute a family distinct from the Malachiidffi; their entire habitus is different, and the most important of the special peculiarities of the Malachiid}>?, viz., the extensible vesicles, is completely un- known among them ; their integuments, furthermore, are hard and thick, and resemble those of the Cleridie rather than the Mala- chiidiB. The Melyridj\^ constitute a moderately large family, which is so homogeneous that it is ditlicult to find man\' valid characters to define even the genera, and the groups higher than genera are ver}'^ few in number. The species are exceedingly abundant west of the 100th meridian, and increase in number and variet}' to the westward, following the same law as the Hetero- mera, except that they are relatively more abundant perhaps in the true Pacific coast fauna. The famil}' is essentially subarctic, and is ver^- poorh' represented south of our Mexican boundary. It is not necessary to allude in the present preliminary essay to the general structural details of the famil}^ as these are given with sufi[icient fullness in many systematic works, and also be- cause all those structures which, by reason of diversification ap- parently afiord eflScient means of grouping the species, are men- Goleopterological Notices, VI. 45T tioned in the tables given below or in the notes under the various generic headings. It should be stated, however, that the reason for the enormous proportion of new species here proposed, is to be found in the fact that the famil}^ has been almost totally neg- lected by systematists in this country for about thirty years, and that at the date of the last S3'nopsis b}" LeConte, the extreme western country, where these forms particularly abound, had been scarcely explored in even a superficial manner. A very large number of new species will still have to be described by future investigators, for, at the present time every collection, however small, made in those regions with their numerous local faunas, is made up to a considerable extent of nondescripts. The ]Mel3'rid;\^ maj- be divided into two very unequal subfam- ilies, as follows : — Maxillary palpi cylimhical, the fourth joint pointed; eyes finely faceted and nude; tarsi with short stiff and inconspicuous hairs beneath Melyrin^e Maxillary palpi longer and much more developed, with the last joint large and triangular; eyes very coarsely faceted and setose; tarsi with long dense hairs beneath Rhadalin^ The second of these subfamilies is composed at present of only two species, constituting the genus Rhadalus of LeConte, while the first probably numbers several hundred in the United States alone. MelyriiN.e. The Melyrini\} can be divided into two tribes, which however possess rather less than the usual tribal weight, as follows : — Basal joint of the tarsi longer than the second, the tarsal claws generally appendiculate Dasytini Basal joint slightly shorter tlian the second; tarsal claws not appendiculate. Melyrini Dasytini. In distributing the multitudinous species of this tribe among numerous genera, the principal taxonomic elements employed re- fer, first, to the form, extent and position of the elytral epipleuraj, their plane being either horizontal, reflexed or inflexed, that is turned upward externally or internally respectively; secondly, to the extent and conformation of the submembrauous ungual ap- pendages, and thirdly, to the presence or absence of external spines on the anterior tiljiic Other characters are occasionally 458 Goleopterological Notices, VI. employed to isolate certain aljenant foiiiis. as may l»t* seen from the following table : — Elytral epipleiiric distiuctly (Iftiiiod, at least toward base 2 Elj'tral epipleurae completely obsolete 13 2 — Epistoma obsolete, the frontal edge finely beaded tln'ou<;hout the widtli.

PRISTOSCEI.IS Lee. The species described by LeConte under the name Prititoscelis f/7-a)uJiceps, offers so many points of divergence from the tA'pical forms of Trichochrous that we are compelled to suggest its gen- eric isolation. The epistoma, for example, is wholly obsolete, the apical margin of the front being finely beaded continuous!}- from side to side; the laljrum is relatively very small and strongl}- transverse, and the mandibles long and stout, the eyes small, prominent and very distant from the base, and the ei)ipleurai nar- row but horizontal, the edges of the elj'tra being distincth" re- flexed. The ungual appendages are as long as the claws and sub- equal, but the inner is detached from the claw through outer third of its leno-th. 460 Goleopterological Notices, VI. 1.

Length 3.7 mm.; width 1.3 mm. California. A remarkably distinct species, descril)ed above from the male. I have not seen the female, which ma}^ differ greatly in the size of the head. The male sexual characters at the abdominal apex are very simple, the fifth segment being rather narrowh' truncate at tip. ErDASYTES n. gen. The three species which it seems advisable to separate from Tricliochrous under this name, do not form a very distinctly characterized genus, and differ only in having the epipleura? rather wide, flat and horizontal, and the lateral margins of the el3tra narrowly- reflexed, this being a consequence of the epipleu- ral structure. Still, if we regard epipleural structure as one of the few important taxonomic elements in this tribe, it will cer- tainl}' be necessary to form of these species a genus different from Tricliochrous, and, after all, when we compare the structure of Crothorax and somewhat more than twice as long, par- allel, the sides feebly arcuate, becoming straight near the base; disk obli(iuely narrowed at apex, each elytron rounded; lateral margins reflexed ; punctures fine and rather sparse. Abdomen more densely cinereo-puljescent. Length 3.8 mm. ; width 1.9 mm. Californiu. The description refers to a single female type from an unre- corded part of the State. The epipleunv are rather wide, sub- horizontal, polished and impunctate, becoming iuAvardly arcuate at tip and vanishing only at the beginning of the rounded apical angles. It is probable that the male will be found to ditier con- siderably in general form. 2. Ell. o1)loii§:us n. sp. — Oblong, stout, strongly convex, polished, black, without metallic lustre, the elytra somewhat piceous; legs pale rufo-ferrugin- ous throughout, the coxai dark; antennse rufo-testaceous, blackish toward apex and also at the inner extremities of the intennediate joints ; pubescence cin- ereous, subdecumbent, long and very sparse anteriorly, rather dense and inter- mingled with sparse erect pale set;c throughout on the elytra, the head with a few bristling setiis; marginal cilia long and ratlier confused. Hiad scarcely more than three-lifths as wide as the ]n-othorax, smooth, finely, sparsely punc- tate, the impressions long and pronounced, extending almost to the occiput; ei)istoma somewhat sliort; laln'um moderate, rounded; eyes rather large, mod- erately convex; antennie stout, serrate, incrassate, moderate in length, the penultimate joints strongly transverse.

Abdomen a little more densely cinereo-pubescent. Length 2.9-4.8 mm.; width L4-2.2 mm. Utah (southwestern). Mr. C. J. Wcidt. The male descril)ed has the fifth ventral truncate at apex, the genital segment fiat, finely canaliculate along the middle and sinuato-truncate at apex and the inner spur of the anterior and Goleopterological Notices, VI. 463 middle tibi;e moderatel}' dilated, the anterior tibiit^ and tarsi un- modified. The female has the head about one-half as wide as the prothorax, the latter three-fourths wider than long and still quite as wide as the el3'tra, with the sides rounded and convergent near the apex, and the elytra somewhat more than one-half longer than wide. The individuals vary greatly in size independenth'' of sex. Six specimens. The epipleur?e are flat, horizontal, polished and glabrous, curv- ing inward posteriorly and ending at the narrow apical trunca- ture. 3. Eu. iirsiiitlS n. sp. — Obloug, stout, strongly convex, iwlislied, intense black throughout, ^vithout metallic lustre; legs and antenniB black ; vestiture rather long, sparse, blackish, intermixed with numerous long erect black setse, especially abundant on the elytra ; marginal cilia black, long but some- what fimbriform. Head but slightly more than one-half as wide as the pro- thorax, smooth, finely and sparsely jjunctate, the impressions moderate in size and distinctness; epistoma rather short, dark; labrum strongly rounded, grad- ually slightly pale toward tip; eyes large but not very prominent; antennaj stout, one-third longer than the prothorax, distinctly incrassate toward tip, the penultimate joints transverse, fifth scarcely dilated. Profhorn.r very nearly twice as wide as long, the sides parallel and very feebly arcuate, slightly con- vergent and more arcuate near the deflexed apical angles, which are but slightly prominent anteriorly and somewhat broadly rounded, basal angles slightly ob- tuse and distinct, not rounded; apex subequal to the base, truncate; base broadly arcuate; disk strongly convex, finely, remotely punctate. Elytra scarcely more than one-half longer than wide, equal in width to the prothorax, parallel and straight at the sides, evenly and not broadly rounded at apex, the sutural angles not very blunt; disk narrowly reflexed along the side margins, rather coarsely and sparsely punctate, the interspaces polished. Abdomen moderately densely clothed with short plumbeo-ciuereous pubescence. Length 3.0-3.2 mm.; width 1.4 mm. Southern California. This species may be recognized by its black color and long hispid black setae. The description is drawn from the male, in which sex the fifth ventral is but little longer than the fourth, slightly trapezoidal and truncate at apex. The female differs onl}^ slightly, the elytra being fully three-fifths longer than wide and somewhat wider than the prothorax, the sides of the latter more arcuate; the head is fully as large or even somewhat larger, when compared with the [)rothorax, in the female than in the male. Two specimens. The epipleuriij are flat and horizontal, and, at the apex, have their plane turned somewhat inward and upward. 464 Coleopteroloyical Arttices, VI. ASV0.4TES n. gen. This genus dirters but slightly from Trichochrous. but the smull prothomx and broad subdepressed el^'tra, which are nar- rowl}^ reflexed at the sides, give to the two species which at pres- ent compose it, a facies which is quite peculiar and distinctive ; the general habitus is in fact intermediate in some respects be- tween Trichochrous and the genera allied to Allonyx. The epi- pleuraj are broad and Hat, and this character distinguishes it at once from Trichochrous, although in other structural features it is virtually similar. The epipleur;\? are relatively altogether as as wide as in Eudasytes, or even wider; the\' do not, however, follow the apical curve of the elytra as in that genus, but become abruptl}' obsolete at a greater distance from the apex. The spe- cies are mutualh^ verA' distinct in appearance and ma}- be thus distinguished : — Pubescence coarse aud rather dense, not intermingled AWtli erect hairs; abdomen entirely red 1 ruflreiitris Pubescence fine and very sparse, intermixed with short but inconspicuous erect hairs; abdomen red, blackish near the base 2 explaiiatiis It is probable that this genus is local and confined to the coast regions of California near Santa Barbara and Los Angeles, a faunal region which is known to support a considerable propor- tion of endemic forms. 1. A. ril fiTeiitriSi n. sp. — Oblong, sulioval, broad and subdepressed, black, with a strong teneous lustre; elytral apices, abdomen and legs through- out jjale rufous; antennae darker, testaceous, blackisli toward apex; integu- ments strongly shining; pubescence rather coarse, long and somewhat dense, closely decumbent, pale fulvous and \erj conspicuous, without trace of inter- mixed erect setae; marginal cilia short, dense and fimbriform, longeron the elytra. Head two-thirds as \\ ide as the prothorax, nearly smooth, a ery obso- letely reticulate, finely, sparsely i)unctate; impressions feeble and widely separated; epistoma very sliort and broad: hibrum short, subtruncate at apex; eyes large but not prominent, nearly attaining the base; antenna; but little longer than the prothorax, feebly serrate, slightly incrassjite, the penultimate joints transverse. Prothorax three-fifths wider than long, widest just visibly ])ehind the middle, the sides subparallel and stronglj' rounded ; apex arcuato- truncate, slightly narrower than the base; all the angles very obtuse and more or less rounded; disk finely, sparsely punctate, the intei-si«ices smooth, not rugose laterally. Elytra scarcely two-fifths longer than wide and nearly one- half wider than the prothorax, the sides subparallel and nearly straight: apex almost evenly and not ol>tusely rounded; humeri broadly exposed at base; Goleopterological Notices, VI. 465 lateral edges reflexed ; puuctures not very coarse but strong and rather sparse ; edges toward apex tinely serrulate. Abdomen not very densely but coarsely cine^eo-pubescent. Length 2.7 mm. ; width 1.25 mm. California (Santa Barbara). The male tj'pe has the fifth ventral distinctly longer than the fourth, and broadly flattened or impressed and truncate at apex almost throughout the entire width, the impression obsolete to- ward base, more broadly' toward the middle. In the female the head is scarcely visibly smaller when compared with the protho- rax, but the latter is distinctlj^ wader in reference to the elytra being at its widest part fully as wide as the elytral base, which in the male is much narrower. Four specimens. The epipleurjB are very wide, almost horizontal and finely, sparseh' punctate and pubescent, becoming obsolete at a consid- erable distance from the elytral apices and scarcely at all curved inward posteriori}", 2.

Head three-fourths as wide as the prothorax, smooth throughout, rather coarsely but sparsely punctate, the impressions large and ^videly separated; epistoma very short and broad; labrum transverse, truncate at apex; eyes moderate in size, not very convex; antennae slightly longer than the prothorax, serrate, all the joints asymmetric, the fifth and sixth subequal and rather wider than seven to nine, tenth moderately transverse. Prothorax about one-third wider than long, the sides strongly arcuate, becoming gradually convergent and less arcu- ate toward a^iex, the latter feeljly arcuate, much narrower than the base, which is still more arcuate; basal angles extremely broadly rounded and wholly obliterated, the ajjical deflexed and broadly rounded; disk convex, rather coarsely but siiarsel}' punctate, smooth, not at all rugose toward the sides. Elijtra a little more than one-half longer than wide, nearly one-lialf wider than the i)rothorax, parallel, feebly dilated with the sides slightly arcuate, becom- ing parallel very near the base; apex liroadly, evenly rounded, the sutural angles right and scarcely at all blunt; disk subexplanate and with the edge strongiy serrulate externally at apex; lateral edges reflexed; punctures coarse, deep and sparse. Abdomen very sparsely and rather coarsely cinereo-pubes- cent. Length 3.3 mm.; width 1.4 nun. Southern California. Mr. H. C. Fall. The single specimen before me is a female, having the fifth ven- tral segment broadi}- rounded. The species differs greatly from 466 Goleoplei^ological Notices, VI. rujivenb'is in its longer form of body, coarser piuictiuition and sparser and dual vestiture. The pale color at the elytral apex ascends at the lateral margins to about the middle, gradually -be- coming faint. The epipleiirii3 are flat, almost horizontal, polished, and very remotely and almost imperceptibly punctulate and pubescent. TRIC ]IO( IIKOUS Motsch. Itijturo.somus ; Emmenotarsus Mots; Pristoscelis l^ec. (pars.). Within the broad compass which we are compelled to give it, this genus is in all probability one of the largest of the North American Coleoptera, its species occurring in unnumbered scores in the extreme western regions of the continent, and especiall}- in California, where it constitutes one of the chief arboreal elements of the order. Its species differ much among themselves in size and vestiture, but agree in having the appendages of the tarsal claws well developed, equal, as long as the claws and attached to them except in outer third or fourth of their length ; these ap- pendages are of a gelatino-membranous texture, and subject to malformation or distortion which is frequentl}' deceptive and misleading, especially under low powers of amplification. The species may be distinguished from Eudasytes and Asj^lates by the structnre of the epipleurai, and from Listrus and its allies by having the outer surftice of the anterior tibi^t — and of the others to a less extent — beset with an irregular and partially double se- ries of short stiff and widely spaced spinules. The bod}' maj- be simply pubescent or have erect setae in addition, and may have a dense thoracic fringe of short cilia as in Listrus; this regular fringe is however generally wanting in those species which bristle with long erect seta\ The sexual characters are usually quite distinct though only rarely ver}' radical, but the sexes are nearly alwa^^s readil}^ differ- ential)le. The male as a ruje has the head, and less frequently the prothorax, larger, the antennre longer, and the elytra relatively' shorter than the female. The abdominal characters are generally feeble, the fifth ventral in the male being more or less evenl}'' truncate, but in a singular exception described below under the name sexualis, this segment becomes strongly modified, an ex- ception quite as pronounced as that of Cistela brevis when com- ColeopteroJofjical Notices, VI. 46T pared with C. theveneti (Col. Xot. III., p. 163). The third and fourth segments in the males of certain small species with pale elytra have a cluster of short radiating spinules in the middle. The genital segment varies but little; it is generally emarginate in the male and more or less truncate in the female, and is im- pressed along the middle in both sexes. Beyond the genital seg- ment the under part of the dorsal pygidium gives the appearance of still another terminal segment; this inferior surface is more de- veloped in the male. The fifth ventral in the fem.ale is always more or less rounded, and its surface is sometimes feebly im- pressed. In the male the inner spur of the anterior and middle tibife is dilated, sometimes very strongl}^ while in several species I have been unable to notice any modification of the spurs, and in the male of sexualis the inner spur is dilated on all the tibite. In a few species, such as fuscus, the anterior tibise are slightly thickened or bent in the male, but as these tibial modifications are rare and slight I have not searched for them with special care. The literature of this genus is confused in an inexplicable man- ner. The typical form was described by Motschulsky, and the genus limited by him to three species having uniform pubescence without intermixed erect hairs, certain other species such as yriseus and conformis, which, with the large material before me, are not separable from Trichochrous, being at the same time made the types of the genera Byturosomus and Emmenotarsus. When Dr. LeConte published the first edition of the " Classification " in 1861, he for some undiscoverable reason discarded all of Mot- schulsky's names, and proposed " Pristoscelis " for the consoli- dated genera of that author. This course was certainly unwar- ranted, and however much it might be desired on personal or other grounds to retain the name given by LeConte, I feel sure that the adoption of it under the circumstances would be a violation of the laws of priority, as well as some of the principles of ordi- nary justice and equity. But even if we agree to adopt the name Pristoscelis, the condition of the question is not materially im- proved, because the original definition states that the prothorax is " not serrate or ciliate at the sides," and this would exclude all of Motschulsky's Trichochrous proper, as well as serricollis and serridatus, which were subsequently added.

Length 2.9 mm.; width 1.6 mm. California. The only known specimen of this species is likewise a female, and is from an unrecorded part of the State. The species is re- markabl3- distinct in the prominent apical and acutel}' everted basal angles of the prothorax, and in the ver}" short broad form of the bod}-. The epiplenro? are not much wider than in the or- dinary species of the genus, and are gradually narrowed behind, but they are nevertheless somewhat intermediate between the usual type and the broad horizontal form characterizing the genus Eudas3'tes. 3.

Abdomen finely, densely and subasperately punctulate, finely cinereo-pirl)escent ; femora stout. Length 3.7 mm. ; width 1.3 mm. Csilifornia (San Francisco). The description is drawn from the male, and in that sex the fifth ventral is very short, nnmodified on the disk but with the apex broadly truncate and distinctly sinuate in the middle. I have not seen the female. This species is allied to cylindricus, but differs in the very feebly arcuate sides of the prothorax, with conspicuous though not at all prominent apical angles, in the much longer and denser elytral pubescence and red legs.

The male difl!ers but little from the female, having feeble sexual characters at the abdominal apex, but the prothorax is larger, although similarly proportioned and is about as wide as the elytra ; the head is large in both sexes. Several other very closely allied species are indi- cated b}' material in my cabinet. Coleopterological Notices, VI. 479 8. T. castus u. sp. — Elongate-oval, convex, black, polished, the upper snii'ace ■v\'ith a feeble a'neous lustre; legs and antenna^ black, the tibia; and tarsi feebly piscescent; pubescence rather long, deciinibent, cinereous, some- what dense on the elytra, sparser anteriorly.

Castus is allied to several Californian species, but is distinguishable quite readih' by the form of the prothorax, and, from cylindricus'iw ad- dition, by the very much longer and more conspicuous pubes- cence. 9. T. siniiosus n. sp. — Oblong, elongate, convex, black, polished, the ujiper surface with a grayish-subaneous lustre; legs and antenna deep black throughout; pubescence moderately long and coarse, not very dense but cin- ereous and conspicuous.

This species is evidently allied to the preceding, but differs re- markabl}' in the sculpture of the elytra, these being also ver^^ much shorter. The single male in my cabinet has the fifth ventral short and broadl}- truncate at apex, but otherwise unmodified. In both of these species the cilia along the sides margins of the body are rather sparse and are unusually long for this section of the genus. 18. T. griseus Lee— Proc. Acad. Nat.

Legs and antennae dark rufous ; posterior tarsi thick, fully as long as the tibiae. Length 2.5 mm.; width 1.2 mm. California (San Diego) — Cab. LeConte. I am quite uncertain as to the position of this species, since the type is not before me at present, and the published descriptions and short notes taken by me some years ago are not sufficient. According to LeConte the prothorax is gradually but strongly narrowed in front, with the sides feebly arcuate and the hind angles obtusely rounded. The elytra are coarsely punctured. The " last " ventral segment of the male [fifth ?] is said to be longitudinall}' and broadly im- pressed, which is very exceptional in this genus ; the sixth or genital segment is however always sulcate. 19. T. sinilllaiiN n. sp. — Rather stont, oblong, conve.x, black, the legs pale riifo-ferniginous throughout; antennic rufous, slightly obscure at the apex : pubescence rather long, very sparse but white and conspicuous.

Abdomen finely, somewhat densely pubescent, the legs moderately long and slender. Length 2.6 mm. ; width 1.1 mm. Texas (El Paso). Mr. Dunn. The male, if I have correctly identified this sex by the simple but transversely truncate fifth ventral, appears to differ greatly from the usual types of the genus in having both spurs of the anterior and middle tibite simple and slender. The left antenna of the t^-pe specimen is deformed, the third joint being very elongate, enveloping the fourth externally and extending to the base of the fifth. The four specimens before me are quite uni- form in size, but some are slightly- pale and piceous-brown from immaturit}'. 20. T. inoc1e!^tii$ n. sp. — Stout, oblong, convex, piceous-black, the elytra pale and castaneous, polished; legs and antennaj pale rufo-ferruginous, the latter slightly obscure at the extreme tip; pubescence rather long but sparse, pale cinereous, even and distinct, closely decumbent. Head slightly more than three-fifths as wide as the prothorax, polished and smooth but somewhat dull and sul)scabrous anteriorly, where the two impressions are strongly marked ; labrum piceous, broadly rounded; eyes moderate in size; antennae but slightly longer than the prothorax, incrassate toward apex, the tenth joint strongly transverse.

Abdomen finely and rather sparsely punctate, the legs decidedly slender. Length 2.5 n\m. ; width 1.1,1 mm. Kansas. The single male serving as the t^'pe represents a species allied in many structural generalities to simulans, but dirtering in its shorter form, in its rather feel)ler elytral and coarser pronotal l^unctures, and in the very much shorter fringe of pale hairs along the side margins of the body.

The description is drawn from the male, and in that sex the fifth ventral is truncate at apex, with the punctures denser in the middle toward base, the fourth with a few stiffer spiniform set.ie in a cluster at the middle near the apex, and the genital segment is broadly emarginate and medially impresso-canaliculate as usual. The female scarcely differs at all, being merely a little stouter, with a just visiV)ly smaller liead. Five specimens. 24.

The above outline is taken from the female, in which sex the fifth A-entral is rather strongly' rounded at apex ; but the male does not greatly differ, having the head distinctly, and the prothorax slightly larger, with the fifth ventral short and broadly sinuato-truncate at apex, and the genital segment broadly im- presso-canaliculate along the middle, with the apex apparently arcuato-truncate. This species also resembles Listrns, and has the tibial spines rather feebler than in incijnens, but the structural characters place it in Trichochrous wathout doubt ; it is recog- nizable at once by the coloration of the legs. 26.

Abdomen finely, somewhat closely i)unctu- late, finely and thinl3' pubescent, the legs rather long, slender. Length 2.2-2.4 mm.; width 0.9-1.0 mm. California. Both of the specimens before me are females, the fifth ventral being broadly and feebh' arcuate at apex and the genital segment deeph' excavated in the middle. The second specimen agrees with the first in its long mandibles and labrum, but the gelatino-membranous epistoma is wide and distorted, showing that but little reliance can be placed upon the form of this part when it has this soft consistence. In these specimens both the spurs of the anterior and middle tibiie are slender. I have before me a third female from another locality, simi- larl3' colored but narrower, with the sides of the prothorax gradu- Coleopterological Notices, VI. 495 ally convergent from the base, and with short mandibles and lal)rum ; it probably represents a closely allied species. 31.

Leys somewhat long and slender. Length 2.3 mm. ; width 0.8 mm. California (Lake Co.). The unique type of this species is a male and has the fifth ven- tral rectilinearly truncate at apex, with the surface polished and almost impunctate save a few piliferous punctures in the middle toward base ; the genital segment is large, flat, truncate at apex, the latter with a beveled coriaceous edge, the surface feebly di- vided along the median line ; the fourth segment, and, to a less degree the third, has a cluster of coarse punctures in the middle toward apex, which bear short pointed spiniform and inclined setJB which radiate in direction from the median line. This spe- cies is readily distinguishable from umhralus by its dense and coarse vesiture and nubilate maculation. 32.

This species is very distinct in appearance because of its large head, with the eyes small and distant from the prothorax. It is evidently allied rather closely to propinquus, which is known at present onl}- b}- the female, but dift'ers in the dense and conspicu- ous pubescence of the pronotum and black abdomen. The sexual characters of the male are very simple, the fifth ventral being- truncate at apex, and the third and fourth segments completely devoid of modified pubescence. Two males. 85.

Ahtlomcn closely and rather coarsely cinereo-pubescent. Length 2.25-2.8 mm.; width 0.9-1.2 7nm. New Mexico. The male from which the description is drawn is much smaller than the female, and has the fifth ventral evenly truncate at apex but otherwise devoid of modification. In the female the head is only slightly smaller when compared with the prothorax, but the latter is decidedly smaller with regard to the elytra, and the dark elytral stripes are much more evident in the single specimen rep- resenting the latter sex. Two specimens. 42. T. pi'Oiiiiiieiis n. sp. — Oblong, paiallel, rather stout, strongly con- vex, black, without metallic lustre, polished; legs red throughout; antennne blackish, joints three to five more or less rufous; pubescence cinereous, rather long, dec-umbent and sparse anteriorly, dense, shorter, coarser ami inter- mingled with erect cinereous setic uneven in distribution on the elytra; mar- ginal cilia moderately long, pale and fimbriform.

The type is a female, having the fifth ventral broadly subangu- late at tip, the edge however almost concealed b}' the dense and porrect cinereous pubescence. 43. T. Clispidatu!^ n. sp. — Oblong, strongly convex, moderately shining, black, the legs red throughout; antennaj dusky, the third, fourth and fifth joints more or less testaceous; pubescence cinereous, short and very dense throughout, intermingled on the elytra with erect cinereous setse Avhich are moderate in length, uneven and rather close-set; marginal cilia short, dense on the prothorax, much longer on the elytra, timbriform and ashy.

L('g>i and abdomen cinereo-pubescent. Length 3.3 mm. ; width 1.4 mm. California (southern). This species is founded upon a single male, apparently from the same source as the preceding female, but the differences are so radical in the structure of the epistoma and basal angles of the prothorax that it seems impossible to consider the two forms as a single species. In this male the fifth ventral is verN' short, and is broadl}' sinuato-truncate at apex. 44. T. indtltiiN n. sp. — ]-^longate-oval, strongly convex, black, the legs red with the tarsi somewhat dusky; antennie black, joints two to four more 504 CoJeopterological Noficet^, VI. or less testaceous; pubescence pale yello\visli, moderate in lenj^th, rather coarse, dense throughout, the longer pale hairs of the elytra scarcely evident, being much inclined; marginal cilia very short, dense, recurved and finibri- form on the prothorax, very much longer and sparser on the elytra.

Elytra three-fourths longer than wide, scarcely visibly wider than the prothorax, parallel and straight at the sides, semi-circularly rounded at apex, finely and densely punctate, the interspaces smooth, slightly rugiform as usual by anteri- orly oblique light. Ahdomen finely, densely punctulate, densely cinereo-pu- bescent, the legs moderately long. Length 3.U mm.; width 1.2 mm. Arizona. This distinct species is represented before me by a single female from an unknown part of the Territory. The longer hairs of the elj'tra are so mnch inclined and so indistinct that their presence might readily be overlooked, and the species assigned to the preceding subdivision of the genus. 45. T. fililbl'iatus n. sp. — Oblong, parallel, evenly convex, piceous- black; legs and antenn;e blackish throughout; vestiture moderately long, coarse, dense throughout, bright fulvous in color, the elytra Avith long, erect, very coarse and conspicuous settc of the same color, uniformly distributed over the entire surface; marginal cilia rather short, very dense, reclined and fim- briforra on the prothorax, much longer on the elytra, pale. Head three- fourths as Avide as the prothorax, convex, finely but strongly, sparsely punc- tate; interspaces smooth and polished throughout; frontal impressions almost obsolete; epistoma extremely short and broad; labrum strongly rounded; eyes large but only moderately prominent; antennie distinctly longer than the pro- thorax, rather slender, feebly incrassjvte, the penultimate joints moderately trajisverse, fifth scarcely at all dilated.

Elytra fully one-half longer than wide, not at all Avider than the Avidest part of the prothorax, parallel, serai- Coleojiterologicai Notices, VI. 505 circularly rounded behind, rather finely but strongly punctate with polished interspaces, which are relatively much wider than the punctures. Abdomen and legs polished, coarsely but not very densely cinereo-pubescent. Length 2.7 mm.; width 1.1 nun. California. The male type of this very isolated species has the fifth ventral short and broadly, feeLly sinuato-truncate at apex, but without further modification. Fimhriatus may be known at a glance by the very short angulate and strongly- fimbriate prothorax, very coarse and bristling pale setfe of the elytra, and by the fulvous pubescence. 46. T. priiiiiosiis n. sp. — Elongate, subparallel, convex, jiolished, black, without metallic lustre; legs and antenna- black, the tarsi slightly rufo-piceous; vestiture cinereous, denuded and mutilated in the types but apparently un- usually short, rather dense, with the erect pale set;v short and only distinct toward apex, intermingled toward the sides of the pronotum with some long .stiff black hairs; marginal cilia long, stiff", black and sparse throughout. Head rather more than three-fourths as wide as the prothorax, convex, finely, sparsely punctate, smooth and polished throughout, the frontal impressions small and very feel )le; epistoma large, arcuato-truncate, strongly trans\erse, pale and cori- aceous; labrum large, broadly rounded, blackish in color; eyes rather large but not prominent, somewhat distant from the piothorax; antennje about as long as the prothorax, not very stout, the outer joints moderately transverse, .strongly asymmetric, with the apical sensitive patches well developed, fifth scarcely dilated, third and fourth feebly picescent. Prothorax long, scarcely more than one-fourth Avider than long, the sides just visibly convergent and very slightly arcuate, more distinctly so near the base, the l)asal angles obtuse but not rounded, slightly prominent though blunt; apical slightly obtuse and nan-f)wly rounded; apex feebly arcuato-truncate, very little narrower than the base, the latter evenly and strongly arcuate throughout; disk minutely, rather sparsely punctate, smooth, not rugose at the sides. Elytra ut'ar\y three-fourths longer than wide, perceptibly wider than the prothorax, evenly rounded be- hind, parallel, finely and rather closely punctate. Ahdomen clothed with somewhat long coarse and cinereous pubescence. Length 15.1-4.2 mm.; width 1.1.5-1. .5 mm. California. The two female types before me differ greatly in size, and have the pubescence not only denuded in great part but more or less broken, so that it is not possible to state its true development with much precision. The species is remarkably distinct, as may be judged by the description, and is one of those forms which it is difficult to assigu to either Byturosomus or Emmenotarsus of Motschulsk3^ proving that tiiose groups are not tenable as genera. 50G Coh'Opterological Notices, VI. 47.

Length 3.0-3.6 mm.; width 1.4-1.7 mm. California (San Diego Co.). The above sketch refers to the female, and the male, as remarked by LeConte, is quite different in form, being less stout, with the head a little more than one- half as wide as the prothorax, the latter scarcely more than one- half Avider than long though similar otherwise, except that the pubescence is a little darker and less obvious in the median parts of the disk, and that the elytra are relatively shorter, narrowed feebly from the base and not at all wider than the prothorax ; in the female the elytra are much more than twice as long as the prothorax, while in the male they are quite as conspicuously less than twice as long. The fifth ventral in the male is broadly and feebly sinuate at apex but otherwise unmodified, and, in both sexes, the pronotum is feebly indented in the middle near the base. 48.

Efi/tra scarcely one-half longer than wide and only just visibly wider than the ijrothorax, parallel, evenly rounded at apex, rather finely but strongly and closely punctate. Length 2.6-3.2 mm.; width 1.15- 1.45 mm. Utah. The description refers to the male, in which sex the intromit- tent organ is in the form of a flattened cylindrical sheath, ob- liquely truncate at apex, with the inferior surftice produced at tip in a fine slender cusp-point. In the female the head is not more than two-thirds as wide as the prothorax. Numerous specimens. Several specimens apparently" not differing otherwise, have the legs and antenna? rufous throughout, the apical joint of the latter blackish. 49.

Abdomen somewhat thinl}' cinereo-pubescent. Length 2.5 mm.; width 1.0 mm. California (southern). The description is taken from the fe- male, which is the only sex which I have seen, and in that sex the fifth ventral is evenly and strongly rounded behind. The species may be readily distinguished from the others wdiich immediately precede by its more asperate sculpture and smaller size. 52. T. vilis n. sp. — Oblong, moderately convex, dull, the elytra shining, black, the legs pale ferruginous throughout; antennit' black, gradually pale toward base, the first joint palest; pubescence rather long and coarse but only moderately dense, not at all concealing the surface, cinereous, the semi-erect pale hairs very sparse and only visible toward the sides of the elytra; mar- ginal cilia long and pale throiighout, scarcely fimbrif orm. Head three-fourths as wide as the prothorax, asperately though not densely punctate, the inter- spaces strongly reticulato-rugose; impressions very feeble, epistoma moderate in length, partly pale; labrum small, almost semi-circularly rounded; eyes moderate, slightly prominent, not attaining the base; antenntc well developed, one-third longer tban the prothorax, comiiaet, the outer joints not at all asym- metric and feebly transverse, fifth only just visibly larger.

Abdomen rather thinly cliiereo-i)ubescent, the legs decidedly thick. Length 1.7-2.6 mm.; width 0.8-1.15 mm. California (San Diego). Mr. Dunn. The female differs from tlie above described male in its larger size, relativel}' longer and wider elA-tra, smaller head, more slender a nd less claviform anterior tibia? and especiall}^ in its much shorter and more slender antenntx^, with the fifth joint distinctly dilated and very transverse, the sixtli and eiglith being small; also in the smoother sculpture of the pronotum. The fifth ven- tral of the male is very short and transversely truncate. This species, which was taken in some abundance, is evidently allied to brevicornis, but may be distinguished by the sparser vestiture, less transverse prothorax wiiich is more evenly rounded at the sides, and b}' slight differences in the antennal structure of the female. 53. T. insigllis n. sp. — Oblong, stout and convex, polished, l)lack; legs and antennae black with the funicle of the latter slightly pale toward base, and the tarsi piceoiis; pubescence rather long, dense and decumbent, pale luteo-cinereous, becoming blackish in a discal spot on each elyti'on near the base and another much larger behind the middle; body bristling throughout with long erect black sette. Head scarcely more than one-half as wide as the prothorax, smooth, finely but strongly and sparsely punctate, the impressions very feeble ; epistoma long, truncate ; labrum long, strongly rounded at apex ; eyes rather large, nearly attaining the base; antennae somewhat slender and scarcely at all incrassate, a little longer than the prothorax, the outer joints not asymmetric and but feebly transverse, fifth only slightly dilated.

Elytra one-half longer than wide, only slightly wider than the prothorax, parallel and straight at the sides, evenly but rather broadly rounded at apex, the punctures tine but strong and rather close-set. Abdomen very minutely and densely i)unctu- late, densely clothed, as are also the legs, with luteo-cinereous i)ubescence. Length 3.6-4.0 mm.; width 1.6-1.8 mm. California (southeastern). The two representatives of this striking species before me are both females, and the second specimen has the two large dark spots on each elytron subconflnent, the posterior pair uniting also transverselv on the suture.

Etytra scarcely two-fifths longer than wide, distinctly wider than the prothorax, parallel and straight at the sides, broadly and evenly rounded at apex, finely and moderately closely punctate. Abdomen rather thinly cinereo-pubescent. Length 8.5 mm.; width 1.5 nnn. California. The type of this species is also a, female. It resembles i)i- signis at first sight, because of the four quasi-denuded spots of the elytra, but ma^^ readil}' be distinguished hy the pale legs, short prothorax with more obtuse apical angles, shorter and broader epistoma and labrum, longer antennae and other char- acters. A single specimen from an unrecorded part of the State. Another female, evidently immature, represents a species closely allied to this but without the dark elytral spots, with a less transverse prothorax and with much more numerous erect black setae. 55.

Length 2.4-3.75 mm. ; width 1.1-l.T mm. California (San Diego). An abundant species, represented in my cabinet by a large series exhibiting as usual great variability in size. The description here given is taken from the male, and the female is broader with a relatively more transverse prothorax, slightly smaller head and parallel elytra which are more broadly rounded at apex. I cannot distinguish the original types of con- formis from this species. 56.

A very distinct form, represented before me by numerous speci- mens displacing consideiable variation, the central dark area of the pronotum being wholly obliterated in some cases. The male above described differs from the female in its smaller size and narrower form, and the female has the elytra larger and parallel, the antennae relatively shorter and the head barelj^ three-fourths as wide as the prothorax ; the fifth ventral of the male is feebly sinuato-truncate at tip.

Elytra nearly two-thirds longer than wide and one-fourth wider than the prothorax, parallel, dehiscent and broadly rounded behind, finely but strongl}', not very densely punctate. Length 3.4 mm.; width 1.35 mm. California (southern). The description given above refers to the female, and the species exhibits a close artinity with sutii- 514 CoUopterological Notices, VI. ralis, differing in the nature of the vestiture, narrower form of the body, and in the smaller and narrower prothorax of the female. 58. T. reiuotus ii. sp. — Elonjiate, suboval, convex, iK)lislicd, lilack, with- out metallic lustre; legs and antennjv black tliroufihoiit; pubescence coarse, sparse, subdeciiuibent, in great part cinereous on the pronotum, blackish with cinereous hairs confusedly interspersed on the elytra especially near the suture, apex and flanks; entire body bristling with numerous very long erect blackish set:e.

Abdomen densely ciuereo-pubescent, the legs well developed. Length 3.5 mm.; Avidth 1.3 mm. California. A single male from an unknown part of the State serves as the type of this species ; the fifth ventral is unusually long, trapezoi- dal and truncate but otherwise unmodified, and the inner spur of the anterior and middle tibiae is widely dilated Remotus may be distinguished from quadricollis by the rounded sides of the pro- tliorax and much smaller head. 50.

This species may be distinguished from the preceding by its much more slender form, anteriorlj^ convergent sides of the pro- thorax and shorter erect setfe of the elytra, as well as by the more abundant cinereous pubescence, which last however is a vari- able chai'acter. It is represented by a single female example. 60.

LISTRrS :Motsch. The genus Listrus, as here considered, is an extensive and very homogeneous aggregate, characterized by an elongate and sub- parallel convex body, generally sparse and variegated vestiture without intermixed set;^, slender tarsi in both sexes, with the basal joint of the posterior slightly longer than the second, the fifth somewhat dilated toward tip and canaliculate above at apex as usual throughout the family, the anterior tibi;e slender, cylin- drical, usually with closely decumbent ashy pubescence and only Coleopterological Notices, VI. 541 occasionally with two or three very slender distant external spines, these being completely obsolete as a rnle. Antennae short, feebly incrassate, only slightly thongh dis- tinctly serrate, with the first joint always much dilated and darker in color, the fifth larger than the fourth or sixth, and the eleventh evenly elongate-ovoidal and obtusely acuminate. The prothorax is dilated toward base, with the lateral edges minutely serrulate and having a close-set even fringe of short posteriori}' and supe- riorly recurved setae, which are almost invariably pale ash}' white in color, the apical angles alwaj's very obtuse. Epipleurai very narrow but dilated toward base, with their plane strongly in- clined upward throughout. The ungual appendages are thick, equal and fully as long as the claws, the apical third or fourth of which is free. The author of the genus did not seem to have a very clear con- ception of its real scope, as the first species which he assigned to it — constricticollis (=zconstrictus Lee.) — is generically quite dis- tinct from the species of LeConte and Mannerheim, which he subsequently states should be included, and which alone agree with his generic diagnosis in having the sides of the prothorax serrulate. The other tvvo species described by Motschulsky have not been identified and are probably also generically different from rotundicollis, canescens, etc. I agree with LeConte, how- ever, that it is probably the best course to regard Listrus as con- stituted below, and not as the equivalent of Eschatocrepis Lee. Our species are numerous, and those before me may be quite readily distinguished among themselves as follows : — Interspaces between the pronotal punctures, finely, evenly and closely punctu- lato-rugulose.

The statement in the table of LeConte (Proc. Acad., 18G6, p. 357), that the prothorax in canescens, difficilis and rotundicollis is not wider than long is very much in error, and is another ex- ample of a singular personal equation previously alluded to (Col. Not. Ill, p. 205), by which the author quoted continually over- -estimates the length of this part of the bod.y in terms of its width; at the same time, it should be said that this overestimation is more or less general among systematic writers, and results largely from a natural cerebral bias which it is difficult to explain satisfac- torih' ; it is only mentioned in the present connection because of its excessive amount. 1. L,. rotundicollis Lee. —Proc. Acad. Nat. Sci., Phila., VI, p. 170 (Dasytes); 1. c, 1H()6, p. 358 (Listrus). Elongate-oval, strongl}^ convex, polished throughout, l)lack with a dark steel-blue metallic reflection ; legs and antennw black throughout; pubescence very short, decumbent, coarse and sparse, denuded near the suture behind the middle of each ely- tron, longer and finer beneath.

The alcove outline is taken from the female, in which sex the fifth ventral is much longer than the fourth, truncate at apex and unmodified on the disk. In the male the fifth segment is, according to LeConte, somewhat excavated longitudinally, the excavation fringed Avith black velvety pubescence. CoIeopte7'ological Notices, VI. 545 2. Li. interstitialis n. sp. — Elongate-oval, convex, polished, black, the elytra with greenish, the pronotuni with subcupreous metallic reflection; legs black; antenna- black, the second joint and the third less distinctly tes- taceons; pubescence moderately short, sparse, denuded on each elytron in two large spots in basal half and several confused spots behind the middle especi- ally toward the suture. Head three-fifths as wide as the prothorax, sparsely but deeply perforato-puuctate, feebly granulato-reticulate, obsoletely biim- pressed toward apex; eyes moderately prominent; antennie quite distinctly longer than the prothorax, rather slender, feebly incrassate.

California (Sonoma Co.). This species and the preceding are distinguished from all others of the genus b}- the peculiar sculpture of the pronotum, and inter stitialis differs from rotundicollis in its longer and less convex elytra, longer pubescence, color of the antennae and pecu- liarities of thoracic structure previously stated.

Legs somewhat stout, black, picescent toward apex. Length 3.0-3.75 mm.; width 1.0-1.3 mm. California. One of the largest species of the genus and readih^ distinguishable by its long pubescence. The description is drawn from the female, for more advantageous comparison with others represented by that sex alone. The male is, as usual, smaller and narrower, with the head three-fourths as wide as the prothorax and with slightly more prominent eyes, the fifth ventral unmodi- fied on the disk and broadly sinuato-truncate at apex, the genital segment transversely oval, flat and completely unmodified on the disk but clothed with longer blacker and more erect hairs ; the fifth ventral of the female is longer and slightly deflexed at the apex. 4. Li. lliontaillis n. sp. — Elongate-oval, strongly convex, polished with a feeble viridi-a'neoiis lustre; pubescence long and rather dense, the elytra with rounded and widely isolated denuded spots which are less evident toward base. Head nearly three-fourths as wide as the prothorax, with the eyes some- what prominent; punctures moderate in size, close-set, the interspaces with feeble scattered dents; frontal impressions feeble; antennse rather long, about one-half longer than the i>rothorax, piceous-black, witli the second joint evi- dently scnnewhat pale.

Elytra nearly twice as long as wide, distinctly wider than the prothorax, parallel, obtusely parabolic in apical third, moderately coarsely, sul)rngosely and decidedly densely punctate. Leon moderately slender, black, the tarsi picescent. Length 3.5-3.6 mm. ; width 1.2-1.25 mm. California (Dunsmuir, Siskiyou Co.). Mr. Wickham. The four specimens before me represent a species somewhat al- lied to iJiterruptus, but diflfering in its larger size, longer, more finely and densely punctate elj'tra, and in the sexual characters of the male, the fifth ventral in that sex being l)roadly and very feebly sinuato-truncate and completel}' unmodified on the disk, with the vestiture closel}' decumbent throughout. The descrip- Coleopterological Notices, VI. 547 tion is taken from the female, which is shorter and thicker in body than the male but not larger in size. 5. L,. iiiteri'uptiis Lee. — Proc. Acad. Xat.

Elytra three-fourths longer than wide, distinctly wider than the prothorax, acutely ogival in apical third, coarsely and deeply punctate, the punctures separated b^^ about their own widths, finer toward apex. Legs stout, the tarsi rufescent, the posterior distinctly shorter than the tibiae. liength 2.9-3.5 mm.; width 1.0-1.25 mm. Nebraska to California. The description is drawn from the fe- male, the male being narrower, with relatively much larger head and with the tips of the elytra less acute. The fifth ventral of the male is broadly but strongl}^ sinuato-truncate at apex, flat- tened on the disk and clothed with long erect and bristling hairs, which become black in apical half. This species extends westward to the crests of the Sierras in California, but does not descend the western slope of the mountains. 6.

Scutellum densely pul)escent. Elj/tra four- fifths longer than wide, scarcely wider than the prothorax, parallel, parabolic in ai)ical third or fourth, coarsely, deejily and rather sparsely punctate. Lci/a moderately long, the hind tarsi much shorter than the tibiic. Length 3. 3 mm. ; width 1.2 mm. California (San Francisco). Mr. Dunn. The single t3'pe is a female, having the fifth ventral rather long with the surface feebly reflexed at apex, the latter bristling with dense pubescence. The two basal joints of the hind tarsi are subequal in length, but in another female, which I took at San Francisco, the basal joint is distinctly longer than the second, and, as the prothorax is much less transverse, it probabl}- repre- sents a closely allied but distinct species. This species is distinguishable at once from motschulskiij with which alone it can be confounded, b}^ its much shorter pubescence, sparser and coarser punctures of the pronotuni and other characters, 7. Li. deiisicollis n. sp. — Stout, oblong-oval, somewhat depressed above, polished, black with a greenish-brassy lustre; legs and anteunse black, the second joint of the latter feebly picescent; pubescence short, sparse, cinereous, not very persistent, denuded in large indefinite patches on the elytra. Head three-fifths as wide as the prothorax, densely punctate, somewhat dull, the in- terspaces polished though feebly rugose; frontal impressions distinct; eyes moderate and at a considerable distance from the base; antenn;e only very little longer than the prothorax, the tenth joint one-half wider than long. Prothorax one-half Avider than long, widest at basal third, where the sides are rather broadly and evenly rounded, thence strongly convergent and feebly arcuate to the apex, the latter truncate and scarcely narrower than the pedun- culate base ; apical angles very obtuse and rounded ; lateral serrules strong ; disk somewhat finely but deejdy and closely pcrforato-punctate, the intervals flat and feebly, sparsely punctulate, only slightly wider than the punctures; rugose area occupying rather nu)re than lateral fourth. Elytra oblong, two- thirds longer than wide, fully one-third wider than the prothorax, parallel, parabolic in apical third; humeri tumid and prominent; punctures rather coarse deep and sparse. Abdomen alutaceous, rather strongly but finely reticu- late and punctulate, the legs moderately long, the hind tarsi much shorter than the tibiai Avith the basal joint but slightly longer than the second. Length 3.2-3.8 mm. ; width 1.2-1.4 mm. California (Napa Co.). Coleopterological Notices, VI. 549 Described from the female and the male is still unknown. This is a distinct form, readily identifiable l)y the dull and densely sculptured pronotum, with unusually strong lateral serrulation, broad form and coarse sparse elytral punctures. Three speci- mens. 8. I^. plemis n. sp. — Elongate-oval, strongl}' convex, polished, black, without metallic lustre; legs throughout and antennaj black, the second joint of the latter piceous; pubescence short, sparse, feebly persistent and denuded in large irregular areas on the elytra. Head fully three-fourths as wide as the prothorax, finely but deeply, sparsely perforato-puuctate, the interspaces flat and somewhat rugose especially toward the eyes, the latter rather large but not prominent and situated near the base; frontal impressions broad and dis- tinct; antennae slender, quite distinctly longer than the prothorax, the tenth joint about as long as wide. Prothorax two-fifths wider than long, the sides evenly and moderately convergent and feebly arcuate from near the base to the obtuse and somewhat rounded apical angles; apex l^roadly arcuatd-trun- cate and wider than the pedunculiform part of the base, which is more pro- nounced than usual ; disk widest at basal third, moderately coarsely, deeply and very closely perforato-punctate, scabrous and opaque in latei-al fourth; punctures separated by barely their own dimensions, the narrow interspaces sparsely and feebly punctulate. Elytra three-fourths longer than wide, fully one-third wider than the prothorax, parallel, acutely parabolic in apical third, coarsely and rather sparsely punctate, much more finely so toward apex. Length 3.0 mm.; width 1.2 mm. Vancouver Island. The single female type represents a species which cannot readily be confounded with any other known to me, being allied to densicollis only in the very close punctuation of the prono- tum, but dilfering remarkably in its relatively larger head and ver3' much more slender antennce ; the sides of the prothorax are less convergent anteriorly than in densicollis, as might be infer- red from the large head. 9. L,. subaeiieus n. sp. — ^Moderately elongate and convex, polished, with feeble cupreo-a;neous lustre; legs throughout and antenmc black, the second joint of the latter feebl^^ testaceous; pubescence moderately short, .sparse, denuded in large spots on the elytra and readily removable. Head three-fourths as wide as the prothorax, the eyes somewhat prominent; punc- tures fine and rather sparse ; frontal impressions widely separated, very deep and less diffuse than usual ; antennaj slender, very much longer than the prothorax, the tenth joint about as long as wide and slightly asymmetric.

Lef/s moder- ately long, the hind tarsi slender, only slightly shorter tlian the tibiae. Length 3.1-3.7 mm.; width 1.1-1.3 mm. California (Xapa and Sonoma Cos.). The punctures of the head and pronotum are much more shal- low than usual. A specimen before me, assumed to be the male of the above-described female, has the head relative!}' only slightl}' larger and the eyes only a little more pi'ominent, the fifth ventral much shorter, with its tip truncate, feebly deflexed and with a broadl\' obtuse median cusp, the surface with a small deep rounded fovea at the middle but without erect hairs, the genital segment not visible, but with the under surface of the dorsal pygidium largeh^ exposed behind. The male modification of the fifth segment is similar to that indicated by LeConte for his difficilis (Proc. Acad., 1866, p. 358), but several species were included by the author under that name, and the male of the true difficilis has no such medial fovea, as can be proved b}' a large series taken by the writer in the vicinity of San Jose. 10. L.. iiiacillOKUJii n. sp. — Elongate, parallel, narrow and convex, pol- ished, with a vfrv faint bluish-metallic lustre; pubescence short, rather abundant and persistent, denuded in large isolated spots on the elytra, these spots not forming fascite posteriorly. Head rather more than three-fourtlis as Avide as the prothorax, the eyes prominent, distant from the base by nearly one- half of their length; punctures tine but deep, rather sparse, the frontal im- pressions wide and moderate; antennte long, almost equalling the head and prothorax, lilack, with the second joint scarcely paler, the tenth perceptibly longer than wide, eleventh oval. Prothorax scarcely one-half wider than long, Avidest and evenly rounded at basal third, the sides thence rather strongly con- vergent and nearly straight to the apex, the latter arcuato-truncate and not quite as Avide as the head ; disk finely but deeply, not very densely perforato- punctate, rugose in much less than lateral fourth; interspaces sparsely and feebly variolate or indented. Scutellum moderate in size, albido-pubescent. Elijtra twice as long as Avide, not evidently Avider than the prothorax, parallel, rather obtusely parai)olic in about apical fourth ; humeri rounded, scarcely at all tumid; punctures moderate in size, rather feeble and close-set. Legs black, moderately long and slender. Length 3.25 mm. ; Avidth 1.1 mm. California (San Francisco). Mr. Dunn. Coleopterologicnl Notices, VI. 551 The unique example is a, male and has the fifth ventral fiat, completely unmodified, with the usual sparse decumbent pubes- cence, and with the apex broadly truncate. The antennae are un- usually long, and this is probably a specific character, as I have not been able to note much variability- in this organ due to sex. 11. L. pardali!^ n. sp. — Oblong-oval, convex, polished, l)lack witli a feeble aeneous lustre; legs black, the antennie black or piceous-black, with the second Joint not distinctly paler, the basal joint large and deep hlack; pubes- cence moderately short, coarse, rather sparse, arranged in a complex pattern on the elytra, of which a narrow une\'en fascia at apical third is particularly noticeable. Head fully two-thirds as wide as the prothorax, the eyes rather large but not very prominent ; punctures somewhat fine and well separated, the interspaces flat and smooth toward the middle; frontal impressions broad but distinct; antennae about one-fourth longer than the prothorax, somewhat slender, the tenth joint as long as wide and scarcely asymmetric. Prothorax transverse, one-half wider than long, the sides feebly convergent and straight in apical half to the broadly rounded angles, becoming parallel and feebly arcuate posteriorly ; apex Ijroadly arcuato-truncate, much wider than the jjeduu- culiform part of the base, which is pronounced ; disk strongly and closely per- forato-pttuctate, the interspaces flat and smooth to^^•ard the middle, scabrous and opaque in distinctly less than lateral fourth. Etijtra nearly twice as long as wide, scarcely wider than the prothorax toward base but feel)ly inflated in apical half, very obtusely and subcircularly rounded liehind ; punctures moder- ately large and somewhat sparse. Legs moderate, the hind tarsi long and slender, almost as long as the tibiae. Length 3.25 mm. ; width 1.25 mm. California (Mountains of Sta. Cruz Co.). The single type is a female. In this species the pattern of cinereous hairs on the elytra is better defined and with the pubes- cence apparently' more persistent than in those which precede, and it is further remarkable in having the fringe at the sides of the prothorax composed of hairs which are longer, stifter and darker than usual, and in the posterior inflation of the elytra. 12.

Prothorax two- fifths wider than long, the sides but feebly convergent from near the base to the obtuse apical angles ; apex broadly arcuate. Elytra two-thirds to three-fourths longer than wide, distinctly wider than the prothorax. Length 2.5-3.2 mm.; width 0.8-1.2 mm. Kansas, Colorado, Xew Mexico and Arizona. The measure- ments apph' to the extremes of a very large series. The fifth ventral of the male is rather more than one-half longer than the fourth, truncate at apex, with the surface slightl}' flat and per- fectly unmodified, the pubescence white, normal and decumbent throughout, except the two usual long black and erect ambula- torial setfe at each side near the apex; the genital segment is l)roadly, feebl}^ bisinuate at apex, flat, with a fine median canali- culation. The dorsal p3'gidium projects behind as seen from be- low, its under surface being clothed with blacker and more erect hairs, and it is probably this which was observed by LeConte (1. c, p. 358), and not the apex of the fifth ventral. 13. L.. clavicoi'nis n. sp. — Elongate-oval, strongly convex, moderately shining, black with a feeble a;neous-nietallic lustre; pubescence moderately long, decumbent, evenly distributed and sparse. Head four-tifths as wide as the prothorax, the eyes prominent, surface densely and rugosely sculptured, the punctures polygonally crowded and rather sliallow; antennae black throughout, moderate in length, with a three-jointed club, the tenth joint trans- verse. Prothnrnx transverse, rather more than one-half wider than long, the sides feebly but distinctly convergent and only slightly arcuate from near the base to the apical angles, which are olituse and rounded; apex wide and broadly arcuate ; base broadly and feebly jtedunculate; marginal fringe short and dense; disk broadly, evenly convex. Elytra oljlong, two-thirds longer than wide, distinctly wider than the prothorax, parallel, rather acutely ogival in apical third; punctures moderately large, deep and decidedly spjirse. Leys somewhat short, deep black throughout. Length 2.5 mm. ; width 0.8-0.9 mm. Arizona. The description is taken from the male, the female being not larger or greatly different in form, but with a decidedly smaller head. In the male the fifth ventral is sparsel}" clothed with ordi- nary pubescence throughout, truncate at apex and unmodified. This species is allied to senilis, but differs in its smaller size and relatively shorter form, in its much sparser vestiture and much shorter and more transverse prothorax. Five specimens. 14.

Head three-fonrths as wide as the prothorax, densely punctato-rugose, the punctures shallow; anterior impressions moderate, separated at the frontal margin by a shining impunctate space; epistoma narrow, polished, impunctate, pale and sirbcoriaceous; labrum dark; eyes rather prominent; an tenuai distinctly longer than the prothorax, somewhat slender, the fifth joint dilated as usual, club feeble, the tenth joint almost as long as wide. Prothorax short, strongly trans- verse, three-fifths wider than long, narrowly rounded and Avidest near the base, the sides thence strongly convergent and nearly straight to the obtuse apical angles; apex feebly arcuate, the base broadly, almost evenly and more strongly arcuate; disk broadly and evenly convex, dull and sculptured like the head. Elytra short, oblong, parallel, barely two-thirds longer than wide, not evi- dently wider than the prothorax, oljtusely parabolic in apical third, the imnc- tures strong, rather coarse and modei-ately close-set.

Legs moderate in length and decidedly slender. Length 2.1 nnn.; width 0.75 mm. California (San Diego). I have only seen the female of this species, which is one of the smallest and most isolated of the genus ; it evidently' belongs to the senilis group, however, because of the uniformly distributed pubescence and three-jointed anten- iial club, but differs completely in the sculpture of the head and pronotum. If). Li. exti'icatus ii. sp. — Elongate, parallel, moderately convex, pol- ished, black with a reddish or cupreous lustre; legs l)lack, the tibiaj ami tarsi pale ruf o-testaceous ; antenna' piceous, the basal joint black, the second testa- ceous; pubescence rather long, moderately coarse, close and semi-erect, cine- reous, with confused denuded spots and lines on the elytra, a fine and strongly ])izigzag band behind the middle and a broader and more even non-interrupted straight fascia at apical fourth being especially noticeable.

Leg^i rather long, the hind tarsi slender. Length 2.8-3.0 mm. ; width l.U-1.1.") mm. California (San Diego). Mr. Dunn. The male, serving as the t3'pe of the above description, has the fifth ventral along the median line very short, not longer than the fourth, the apex broadly but distinctly sinuate and the disk flat and entirely unmodilied, the pubescence decumbent, ash}' and normal; behind the fifth ventral, the horizontal under part of the dorsal pygidium is flattened, transversely' oval and densely clothed with erect blackish hairs. I cannot perceive the true genital segment in any of the four specimens before me. Two examples from L'tah represent a feeble geographical va- riet}', agreeing throughout except that the size is a trifle larger and the pronotal sculpture mucli smoother toward the middle.

Four perfectly uniform male specimens. 18. L. diflicilis Lee— Proc. Acad. Nat. Sci., Phila., II, p. 170 (Dasy- tes); 1. c, l.'^ee, p. 3.58 (Li.strus). Narrow, convex, black, with a greenish-metallic lustre, the pu- bescence nearly as in canescens, the denuded band just behind the middle feebly- bisinuate and the snbapical band frequentlj^ broken into two spots on each elytron. Head three-fourths as wide as the prothorax, the eyes prominent and at some distance from the base ; surface confusedly punctato-rugose ; antenna' pi- ceous, the basal joint black, the second testaceous, outer joints cinereo-pubescent, the tenth as wide as long.

Length 2.5-3.0 mm.; width 0.8-1.2 mm. California (Sta. Clara and Napa Cos.). The female is de- cidedly stouter than the male above outlined, with the head smaller and the elytra shorter and broader; the fifth ventral of the male is short though distinctly longer than the fourth, and is transverseh' truncate at apex, the surface even and unmodified ; the genital segment is broadly' sinuate at apex, with a narrow median canaliculation,and the dorsal pygidium is visible at apex. In the female the fifth ventral is longer, rounded, with the surface deflexed at apex and apparently somewhat impressed. This species is represented in my cabinet by a large series. I have before me three specimens from Truckee, in the Sierras, which are almost undistinguishable from the typical forms of difficilis, but which have the fifth ventral of the male broadlv and feebly sinuate at apex ; they apparently' represent a closely allied species or subspecies. 19. f^, fldelis n. sp. — Narrow, elongate, convex, polished, with a grayish- seneous histre; legs black, the tibite except toward base and tarsi nifo-piceoiis : antennic piceons-lilack, the second joint piceo-testaceons, the basal joint large black and cinereo-pnbescent ; pubescence louii, coarse and dense on the prono- tnin, less dense on the elj'tra.

Prothorax scarcely one-half wider than long; sides broadly rounded toward base, rather strongly convergent and becoming almost straight thence to the brocadly obtuse and rounded apical angles: apex feebly arcuate, wider than the feebly pedunculiform part of the base; disk rather finely and closely perforato- punctate, becoming rugose in much less than lateral fourth. Elytra elongate, four-fifths longer than wide, slightly Avider than the prothorax, subparallel, scarcely visibly dilated posteriorly, the apex evenly parabolic; punctures somewhat coarse, deep and close-set. Leg!< moderately stout, the hind tarsi slender and slightly shorter than the tibi;^. Length 2.75 mm. ; width 0.85 mm. California. The single male before me has the fifth ventral transversely and Goleopterological Notices, VI. 557 evenl}^ truncate at apex, about one-third longer than the fourth, with its surface completely unmodified and clothed with the usual decumbent ashy pubescence. This species is allied to difficilis, agreeing in the general char- acter of the sexual modifications, but diflfers much in its longer elytra, longer coarser denser and more confusedly denuded pu- bescence, less transverse prothorax and other features. "20. L.. tritlis □. sp. — Narrow, elongate and convex, the integuments black, shining and slightly brassy bnt densely clothed with rather long coarse and subdecumbent cinereous hairs, Avhich are generally not at all denuded on the elytra excejit in a few spots behind the middle, of which fonr arranged transversely in the position of the usual fascia at apical fourth are particularly evident, ffend fully three-fourths as wide as the prothorax, the ueck rather strongly narrowed ; eyes moderate in size but decidedly prominent ; punc- tures moderately sparse, the interspaces coarsely rugose but polished ; subapi- cal impressions feeble ; antennae slender, nearly one-half longer than the pro- thorax, piceous-black, the second joint paler, tenth rather longer than Avide. Prothorax two-fifths wider than long, parallel and evenly arcuate at the sides in basal half, thence strongly convergent and straight to the obtusely rounded apical angles, the serrulation very fine and feeble ; apex feebly arcuate ; disk opaque under low power ; punctures moderately close, the interspaces strongly rugose but polished, more evidently and coarsely rugose as usual in rather less than lateral fourth. Elytra long, four-fifths longer than wide, quite distinctly wider than the prothorax, parallel and straight at the sides, narrowly para- bolic in apical third or fourth ; disk rather coarsely, deeply and closely punc- tate. Under surface finely pubescent as usual, the legs black throughout. Length 2.8-.3.0 mm; width 0.9-1.1 mm. California ( Lake Co.). The three males before me represent a close ally o^difficilis, but can be specifically distinguished by the more elongate body clothed with longer, denser and much coarser pubescence, the latter being denuded in definite areas only behind the middle. From fi.delis it also differs in this last character, and in its smaller eyes and more opaque and rugose sculpture of the pro- notum. The fifth ventral is about one-half longer than the fourth, truncate at apex and unmodified on the disk. •21. Lf. confusiis n. sp. — Elongate-oval, moderately convex, black with a feeble reneous lustre on the elytra; legs black, the tarsi slightly pale; an- tenna- i)iceous-l)lack, the second Joint i)aler and piceo-testaceous; pubescence rather long, suberect; moderately coarse, not very dense, consisting of cinereous hairs which, on the elytra, are brownish in certain small scattered spots with indefinite boundaries, brown toward the middle of the pronotum except along 558 Goleopterological Notices, VI. tlie median line.

Elytra oblong, only slightly wider than the prothorax, three-fourths longer than wide, parallel and straight at the sides, parabolic at apex, with a short and narrow sutural notch; punctures rather coarse and sparse. Ler/s moderately long and stout, the hind tarsi slightly shorter than the tibiae. Length 2.7-2.75 mm. ; width 0.9-1.0 mm. California (San Francisco). Mr. Dunn. A single pair of this species was sent to me some 3'ears ago, and the description is di'awn from the male, the female being al- most similar but slightly stouter, with a distincth' smaller head and less prominent eyes. The sexual characters are of the same type as in difficilis, from which it can be known at once by the confused pubescence and shallow opaque sculpture of the prono- tum. A single female from southern California represents a spe- cies closely allied to this, which it would serve no good purpose to define at present. 22. L,.

Coleopterological Notices, VI. 559 Elytra oblona;, barely two-thirds longer than wide, oue-thlrd wider than the prothorax, parallel and straight at the sides, very obtusely parabolic in rather less than apical third; base rectilinearly truncate, the humeri right, narrowly rounded ; punctures moderately coarse, deep and decidedly sparse. Ahitomen alutaceous, finely and feebly punctulate, reticulate and finely, moderately densely- pubescent. Length 2.6 mm. ; Avidth 1.0. California (Mendocino and Napa Cos.). The three specimens in my cabinet are females, the fifth ven- tral being ronnded behind and feebly deflexed, the apex of the ab- domen bristling with a few very long and erect black setfe. Va- riegatus resembles luteipes almost perfectly, but is larger, with a relatively narrower and less transverse prothorax, shorter vesti- ture and black femora. 23. L. incertiis n. sj). — Elongate, convex, polished, black, the upper surface with a strong violaceo-nietallic lustre; legs black, the tilnje and tarsi rufo-piceous ; antennai piceous-black, the second and third joints paler; pubes- cence short, only moderately coarse and dense, in great part denuded on the elytra in large spots toward base and wide irregular bauds at the middle and at apical fourth.

Prothorax one-half or more Avider than long, nar- roAvly rounded and Avidest near the base, the sides strongly convergent and nearly straight thence to the obtuse apical angles; apex broadly and feebly arcuate; disk finely, closely punctate and generally dull, the interspaces sparsely and finely pitted, coarsely rugose toAvard the sides. Etytra three- fourths longer than Avide, parallel, obtusely rounded or parabolic behind, c^uite distinctly Avider than the prothorax, rather finely and not densely punctate. Length 2.5-2.8 mm. ; width 0.75-1.0 mm. California (Sta. Clara Co.). This species is allied to variegatus, and differs in its shorter and more opaque pronotum. The general characters of the de- scription are taken from the male, in which sex the fifth ventral is trapezoidal, broadly truncate at apex and unmodified on the disk ; in the female the head is relatively slightly smaller, but the eyes are almost as prominent as in the male. Five specimens. 24.

Length 2.0-2.5 mm.; width 0.75-0.9 mm California (Los Angeles and Napa Cos.). A common and very readily recognized species in the coast regions of middle and southern California. The above outline is from the male, the sexual characters being as in difficilis: the female is slightly stouter, with a rather smaller head, slightl}' more transverse prothorax, and with the elytra feebly dilated posteriori}- ; there seems to be only slight sexual divergence in the antenna?, but some individuals have the basal joint also pale. 27.

Elytra tAvo-thirds longer than wide, fully two- fifths wider than the prothorax, parallel and straight at the sides, the apex very broadly and obtusely ogival aiul narrowly dehiscent as usual, the sutural angles right and not blunt; base truncate, the hirmeri slightly tumid and rather broadly rounded. Length 1.9 mm.; width 0.7 nun. Nevada (Reno). The two males, which are the sole representatives of this dis- tinct and diminutive species, have the fifth ventral truncate at apex, the disk feebly flattened posteriorly^ the white hairs there becoming slightly more erect and directed obliquely tow-ard the median line. It resembles luteijjes somewhat, but is still smaller and differs conspicuously in the very dense and opaque sculpture of the pronotum under low power. 28. L,. balteelllis n. sp. — Narrow, parallel, convex, the elytra polished and with a feeble jeneous lustre, black, the legs red with the tibiie toward base and tarsi sometimes iiicescent ; antennas black, the f tmicle paler toward base; pubescence rather sparse, that in basal half of the elytra rather long and coarse, cinereous and with only feeble traces of small brown spots, that in the even transverse fascia at apical third apparently a little shorter, denser and more dectnnljent, the apex with scattered pale hairs; dark bands clothed with blackish hairs.

Length 1.9-2.3 mm. ; Avidth 0.(>-0.8 nun. California (San Diego). The description is taken from the male, the fifth ventral being truncate at apex and unmodified on the disk. The female is Goleojiteroloijical Notices, VI. 563 much larger, with relatively broader elytra and a smaller head. The prothorax is decidedh-, though broadl}' pedunculate at base. Of this interesting species I took two specimens some years since; it is distinguishable at once from any other by the colora- tion of the legs, opaque pronotum and uneven vestiture. 29. L. fanielicus n. sp. — Elongate, narrow, convex, black, the upper surface with a feeble subcuiweous tinge, the head and pronotum opatjue, the elytra feebly shining and with faintly reticulate sculpture; legs bright red, the tibife near the base and tarsi slightly obscure; antenna; black, the fuuicle piceo-testaceous toward base ; pubescence irregular, sparse and rather fine an- teriorly, the white hairs of the elytra wide, long, lanceolate and subsquaniiforni, unevenly and sparsely marmorate among the shorter slender lilaekish hairs to- Avard l)a«e, but forming a narrow condensed ti'ansverse fascia at ai>ical third, and also slightly evident toward apex; remainder of the surface clothed sparsely Mith much shorter and more slender dark hairs.

Scutellum quad- rate, densely albido-pubescent. Elytra three-fourths longer than wide, only very slightly wider than the prothorax, the apex rather acutely parabolic; humeri Ijlunt and right; disk strongly, evenly but moderately coarsely and closely punctate. Legs somewhat short and stout. Length 1.8 mm. ; width 0'G5 mm. California (Los Angeles Co.). Mr. H. C. Fall. The single male before me is the type of an interesting and iso- lated species, distinguishable from any other by the coarse and scale-like lanceolate white hairs which are distributed very un- evenly on the elytra ; the white hairs in the preceding species are of the usual structure. The fifth ventral of the male is trun- cate at apex but otherwise unmodified. Famelicus is the smallest species of the genus discovered thus far. 30.

Prothorax three-fifths wider than long, wid- eM and rather narrowly rounded near the base, the sides strongly convergent and nearly straight thence to the apex; disk very densely ininctate, rugose and dull under low power. Elytra but slightly more than one-half longer tlian wide, nearly one-half wider than the prothorax, parallel near the base, dis- tinctly inflated and with the sides parallel and arcuate in apical three- fourths; apex very broadly and obtusely ogival ; disk rather finely but strongly, not very closely punctate. Length 2.0-2.25; width 0.8-1.0 mm. Nevada (Reno). The description relates to the female, and the male is, as usual, smaller and narrower, parallel, not inflated behind, with a larger head and more prominent eyes, and the prothorax only about two- fifths wider than long ; in addition, the basal denuded band of the female elytra is less evident. The fifth ventral of the male is broadly sinuato-truneate at apex but otherwise unmodified. I took a good series of this species, which is not unusually vari- able, although the tibia? and tarsi of some specimens become pale and reddish. DASVTELLITS n. gen. The species of this genus are the smallest members of the tribe Dasytini thus far discovered in North America. The}' are allied to I)asytes,as here accepted, in general organization, especiall}' in having an impressed submarginal pronotal line delimiting a lateral area of greater rugosity, and in the ver}- narrow ei)ipleur;'e which gradually- become subvertical and evanescent behind, but difier in having the ungual appendages well developed and generall}^ fully as long as the claws. The anterior tibia? are slender, clothed rather densely with short and decumbent ashy hairs, and are completely devoid of spinules. The antenna? as a rule are much shorter and more incrassate toward tip than in Dasytes, and the marginal cilia of the body are A'er}- short and lie close to the surface, being usually altogether invisible under low power. Coleojitey^ological Notices^ VL 565 No species with erect hairs interspersed amid the ordinary de- cumbent pubescence are known at present.

The type and only specimen known to me is a female, the fifth ventral being rather long, strongly rounded behind, with the disk feebly impressed in the middle near the tip.

Protliorax two-fifths wider than long, the sides just visibly convergent, evenly and moderately arcuate from base to apex, the angles all obtuse and somewhat rounded though evident; apex feebly arcuato-truncate, very slightly narrower than the base which is only a little more arcuate; disk obsoletely reticulate, finely and sparsely punctate, rugose at the sides, the sublateral impressed line distinct. Elytra two-thirds longer than wide, two-fifths wider than the prothorax, parallel, the sides feebly arcu- ate except toward base; apex evenly rounded; disk finely but very distinctly punctate, the punctures rather close-set and feebly asperulate, the interspaces smooth and polished. Under surface very sparsely and inconspicuously pu- bescent. Length 1.5 mm. ; width 0.5 mm. Arizona. Mr. Wickham. M}' single representative of this species is a female, the fifth ventral being evenly but broadly rounded behind and apparently \Qvy slightl}' impressed on the disk at apex ; the genital segment is smooth, broadly and evenly arcuate at apex, with the disk transversely impressed and not in the least canaliculate along the middle. The ungual appendages are well developed and fully as long as the claws, to which they are attached nearly throughout. This and the preceding are the smallest dasytide forms known to me. 3.

Abdomen sparsely but distinctly ciuereo- pubescent. Length 1.5-1.75 mm. ; width 0.6-0.75 mm. Arizona. The description is drawn from the female, that sex liaving the fifth ventral much longer than the fourth, triangular, with the apex narrowl}' subtruncate ; the male is more slender, with the head four-fifths as wide as the prothorax, the sides of the latter parnllel and broadly arcuate, and the fifth ventral broadly trape- zoidal and feebly flattened tow'ard the apex, which is broadly iircuato-truncate.

This species is evidently rather closely related to the last, l3ut it differs in vestiture, in its more posteriorly broadened form, in its longer epistoma, and in the less narrowl}' truncate subtrian- gnlar fifth ventral of the female. The description is drawn from that sex for facility of comparison, but the male differs scarcely at all, having the elytra A^ery slightly shorter and the apex of the fifth ventral broadly arcuato-triincate. In both of these species the ungual appendage is full}- developed and as long as the claws. Four specimens. 5. D. iiigricornis Bland — Proc. Ent. Soc.

Elytra three-fifths longer than wide, scarcely two-fifths wider than the prothorax, the sides parallel and scarcely arcuate, becoming oblique and feeble arcu- ate toward apex, the latter very narrow and obtuse ; disk finely but strongl}^ rather closely punctate. Length 1.75-1.9 mm.j width 0.8-0.85 mm. Kansas, Nebraska and Texas (Austin). The female described Coleopterological Notices, VI. 569 above has the fifth ventral evenl}^ and strongly arcuate at apex. The single specimen from Austin, which I regard as the male, has the elytra relativel}' shorter and broader, with the fifth ven- tral somewhat narrowly truncate at tip. It is singular that Dr. IjeConte should have failed to observe the strong aflfinity of this species with those which he placed in Dasytes ; there is absolutely no single point of resemblance with Dolichosoma foveicoUis, with which it was associated by that author. 6. D. degeiier n. sp. — Elongate, siiboval, convex, polished, black, the elytra more or less paler and piceous; femora pieeons-black, the trochanters, tips of the femora, tibise and tarsi plceo-ruf oias ; antennae dark piceous, slightly paler toward tip; pubescence coarse, cinereous, decumbent and distinct but sparse. Head three-fourths as w'ide as the prothorax, transverse, feebly con- vex, strongly reticulate and obsoletely punctulate, the frontal impressions feeble and widely separated; epistoma short, the labrum small, transverse and strongly rounded, the mandibles and labrum somewhat pale in color; eyes small but rather prominent; antennse short and slender, distinctly longer tlian the prothorax, the outer joints wider, the penultimate transverse.

Elytra rather short, not quite three-fifths longer than wide, scarcely two-fifths wider than the prothorax, the sides parallel; apex some- what obtusely ogival; punctures fine but strong, moderately close, the inter- spaces polished. Under surface deep black and sparsely pubescent through- oiit. Length 1.5 mm.; width 0.75 mm. Arizona (Benson). Mr. Dunn. The t3^pe above described seems to be a female, the male hav- ing the sides of the prothorax broadh^ arcuate throughout and nearly parallel, with the fifth ventral broadly and feebly arcuato- truncate at tip. There is some variability displayed in the six specimens before me, the upper surface l)eing deep black through- out in some, and, in one example, the prothorax becomes twice as wide as long and almost fully as wide as the elytra ; but I believe that this specimen ma}- possibly represent a closel}' allied though distinct specific form. The specimens are all in rather poor condition. 7. D. elegiiiitiiliis n. sp. — Stout, suboval, strongly convex, moderately shining, black, tlie legsand antennae black throughout; pubescence moderately long, closely decumbent, coarse, cinereous-white, dense, even and very con- 5*70 ColeopteroJor/ical Notices, VI. spicuoxis, without trace of erect hairs.

Under surface dis- tinctly but only moderately densely cinereo-pubescent, the legs slender. Length 1.65-1.8 mm.; width 0.75-0.85 mm. Arizona (near the Canon of the Colorado). The female is described above and this sex has the sides of the fifth ventral convergent, the apex being narrowly arcuato-trun- cate. The male is larger than the female and has the prothorax less transverse, with the sides arcuate and only slightly conver- gent, the apex of the fifth ventral onl}- a little more broadly trun- cate than in the female. Five specimens recently' taken by Dr. T. Mitchell Prudden. 8. D. siiliovalis n. sp. — Stout, oblong, suboval, convex, black, the legs slightly piceous; antennae black; pubescence coarse, dense, closely decumbent and very conspicuous, cinereous-white, with small, widely and unevenly dis- persed spots in which the hairs become dark brown in color though otherwise not dift'erent; erect hairs wanting.

Goleopterological Notices, VI. 5^1 The sex of the type is not clearly determinable, but the two specimens from Arizona are mutually similar and are more prob- abl}' male than female. The single example from Texas seems to belong to the species, although the elytra are relatively larger and more elongate, and the size distinctly larger ; it is not in- cluded in the measures. DASYTES Fabr. This name, as applied to the American representatives, will in- clude those species of the tribe Das^'tini which have the anterior tibiifi slender and devoid of spinules,the ungual appendages equal but very short or rudimentary, and the pronotum with a roughly sculptured and abruptly limited marginal area. The epipleurse are even less developed than in Trichochrous, being moderately "wide with their plane inclined upward at base, rapidl}' assuming the form of a mere fine line very near the elytral margin on the vertical flanks and disappearing completeh* far in front of the apex. The head is much shorter, the eyes smaller and the an- tennre longer and more filiform than in that genus, and the frontal impressions are generally' feeble or obsolete. The erect hairs in- terspersed among the ordinary pubescence are present in some species and altogether absent in others, proving still further that this character is not of generic value in Trichochrous. The species are somewhat numerous and those known to me may be outlined as follows : — Submarginal line of the pronotum strong, Impressed and entire; body gener- ally more cuneiform 2 Submarginal line feeble, frequently only evident as an abrupt division be- tween the smooth and rugose portions of the surface. Elytra without longitudinal vittse 3 Elytra each -with several dark vittiform lines 4 2 — Pubescence distinctly intermingled with longer erect black hairs.

The descrip- tion is drawn from a male taken in the alpine regions of Colorado, and the two similar specimens before me from " Arizona," prob- abl}^ inhabited the high mountain lands if the labels are correct. The allusion to cinereous hairs in the description of LeConte is erroneous as far as the el^^tra are concerned. The ungual appendages are thick and subglobular, unusually developed for this genus, but seem to be attached in rather less than basal half of the claws. 2. I>. obtlisiis n. sp.— Oblong, stout, rather strongly convex, polished, black; femora black, the tibite and tarsi in great part dark piceo-rufous ; an- tennas piceous, gradually testaceous toward base, the first joint again a little darker; pubescence short, sparse, cinereous, intermixed throughout with rather numerous and moderately long erect black hairs, which bristle irregularly also along the side margins.

The male serving as the type has the fifth ventral short and very broadl}' siiiuato-truucate, the genital segment short, flat, apparently not at all canaliculate along the middle and feebly sinnato-truncate at tip; the dorsal pygidium has the lower edge thin and not dilated into a flat plate as in Trichochrous. The lingual appendages are short and basal. 3.

Elytra short, scixrcely more than one-third longer than wide, at apical third much wider than at base and nearly one-half wider than the prothorax; sides arcuate, the apex obtuse and broadly rounded, the sutural angles rounded; disk nearly flat, rather coarsely and closely punctate, the intersjiaces strongly shining.

The unique tj-pe is apparantly a female, but the species may be readily known by its depressed, cuneate form and by the charac- teristics of vestiture detailed in the descrijjtion. It dirters from breviusculuK in its dense pronotal punctures and in the coloration of the antenna' and legs. 4. n. iiitens n. sp. — Subeuneiform, strongly convex, polished, deep black with a faint greenish-nietallie lustre; legs and antenna' deej) Ijlack Coleopterological Notices, VI. 575 throughout, pubescence rather long and sparse, even, suberect, blackish and not conspicuous, slightly cinereous to\vard the base of the elytra externally; mar- ginal cilia very short but finibriforni, black.

Tiie female is described above, tlie fifth ventral being subcon- ical with the apex snbtruncate. The male is smaller and nar- rower, parallel, with the fifth ventral more broadly arcuato-truncate and the antennae still longer and also thicker. This species is allied to bremusculus, but differs in its larger size, coloration of the legs and antennae and in the more elongate elytra. Many specimens. 5. D. breviusculUS Motsch. — Bull.

Length 2.3 mm.; width 1.1 mm. California. The single specimen, which I took in the coast region north of San Francisco, is a female, and the fifth ventral is broadly rounded and feebly impressed in the middle at the apical margin; the genital segment is large, slightly deflexed, broadly angulate at apex and is feebly impressed at the middle of the disk. There can be scarcely any doubt at all that this is the species of Motschulsky, as it agrees with his description in every essential feature ; the species identified by LeConte under the name hreviusculus, is however quite a different thing, Avhich I am unable to place in the absence of the t^-pe, but which ma}- possibly be the nifens described above. 6. D. dissiiiiilis ii. sp. — Elongate, convex, polished, black with a feeble greenisb-jeneous lustre; legs rufous, the femora black except at apex ; antennae blackish, the second and some of the following joints less distinctly, pale; pubescence suberect, moderately long, cinereous, rather sparse and even, a few hairs toward the elytral sides and apex slightly longer than the others l)ut not more erect.

The female described above has the fifth ventral rounded be- hind, the apex subtruncate in the middle, the genital segment being perfectly flat and even and strongly-, evenly rounded at the apex. In general form and vestiture this species more nearly resembles macer, of the next group, than any member of the breviu senilis section of the genus, but difiers in its coarser and sparser elytral punctures and bicolored legs. 7.

Abdomen minutely and closely punctulate, sparsely pubescent. Length 2.9 mm.; width 1.15 mm. California. This species is distinct in having the scattered erect setffi quite well developed anteriorly but subobsolete on the elytra; it is de- scribed from a female from an unrecorded part of the State, and is apparently' unique. 8. D. macer n. sp.— Parallel, rather narrow, moderately convex, pol- ished, black, the legs and antennas black throughout; pubescence cinereous, moderate]}' dense and somewhat short, not very coarse, suberect and inter- mixed toward the sides with a few erect black sette on the pronotum, subde- cumbent, even and without erect hairs on the elytra.

Length 2.2-2.4 mm.; width 0.85-1.05 mm. California and Oregon. This species is common in the coast regions of northern California, and the specimen described above is a male, with the apex of the fifth ventral broadl}' truncate and Coleopferological Notices^ VI. 5*79 apparently very broadly and feebl}- bisiniiate. The head in the female is relatively bnt little smaller, bnt the prothorax is some- what more narrowed toward apex and the elytra just perceptibly and gradually wider behind. The ungual appendages are very short and rudimentary, and the anterior tibiae completely devoid of spinules. I have before me a large series agreeing in every respect with the original type of LeConte. 10. D. depressiiliis n. sp. — Ovoidal, feebly convex, sinning, black; legs riifo-ferriiginous, the hind thighs, except at tip, black, the anterior and inter- mediate piceons-black ; antennit black throughout; labrum, mandibles and apex of the ejiistoma pale piceo-rufous; pubescence cinereous, rather short, moderately dense, intermingled with a few erect black setfe anteriorly and with more numerous, very short and scarcely distinct erect pale hairs on the elytra. Head rather small, three-fifths as wide as the prothorax, strongly and closely punctate and slightly rugose, the impressions nearly obsolete; labrum feebly arcuate at apex; eyes moderately small, convex; antennae long, filiform, the joints rounded. Prothorax twice as wide as long, the sides parallel, distinctly and almost evenly arcuate, the edges feeljly and finely' crenulate; basal angles obtuse but not rounded, the apical feebly obtuse and not very blunt; apex and base subequal, feebly and almost equally arcuate; disk finely and some- what closely punctate, rugose in a wide and feebly delimited lateral area.

Prothorax three- fourths wider than long, the sides distinctly convergent and broadly, almost evenly arcuate from base to apex, the edges finely serrulate; basal angles broadly rounded and apparently obsolete, the apical obtuse; apex sub- truncate, much narrower than the base which is distinctly arcu- ate; disk minutely and sparsel}' punctate, moderatel}' scabrous rather narrowly along the sides, the rugose area abrupt but not limited b}' an impressed line. Elytra one-half longer than wide, near apical third slightly wider than at base and about three-fifths wider than the prothorax, the sides nearly straight ; apex obtusely parabolic and very indistinctly aud minutely serrulate; punc- tures fine, feebly rugose and somewhat close-set. Length 2.0 mm. ; width 0.85 mm. California (San Diego). The description is drawn from a speci- men which has the apex of the fifth ventral broadly truncate and therefore most probablj' male, but the antennae are shorter, the head smaller and the sides of the prothorax more convergent than usual in the corresponding sex of allied species. 12. I>. minutllS n. sp. — Narrow, subcylindrical, rather strongly con- vex, the anterior parts smootli and highly polished, the elytra very obsoletely suhreticulate but polished; body piceous-black, the elytra and alidomen slightly paler; legs pale testaceous; antenna; black, the first joint piceo- the second flavo-testaeeous; palpi black, the mandibles very pale, blackish at the acute apex; pubescence short, cinereous-white, moderately dense, not at all intermixed with erect hairs. Head three-fourths as wide as the prothorax, slightly transverse, minutely and not very closely punctate, the punctures slightly burred toward base; impressions widely separated and feeble; epi- storaa abruptly thinned and depressed at apex, short and black, the labrum .small, broadly rounded; eyes small; antennae rather short, slender, not as long as the head and prothorax, the penultimate joint apparently somewhat transverse. Prothorax large, fully three-fourths wider than long, the sides strongly convergent and feebly, almost evenly arcuate from the broadly rounded and obsolete basal angles to the apex, the latter feebly arcuate, much narrower than the base, which is strongly and evenly arcuate through- out; disk finely, spai-sely punctate, coarsely rugose in an unusually narrow marginal area, which is abrupt though feebly delimited. Elytra one-lialf longer than wide, subequal in \\idth to the i)rothorax, just visibly wider near apical third, the apex obtuse; disk finely, feebly and not very closely punc- tate. Abdomen finely pubescent, the legs slender; ungual appendages about •one-half as long as the claws. Length 1.6 mm.; width 0.65 mm. California. i ColeopteroJogical Notices, VI. 581 The single type before me is undoubtedly a male, and the fifth ventral is broadly truncate at apex. This distinct species recalls some of the small anobiides in general outline ; it probably in- habits the southern parts of the State. 13. D. seniiiiildus Lee— Pioc. Acad. Nat. Sci., Phila., 1866, p. 360. Oblong, rather stout, feebly convex, the integuments smooth a,nd highl}^ polished, black, the legs rufo-ferruginous ; antenna blackish, pale toward base, the first joint darker; pubescence rather short, even, moderately dense, without trace of intermingled erect hairs, cinereous on the elytra at the basal margin and thence posteriorly along the suture to the broad submedian fascia, the apex also cinereous. Head rather small, transverse, two-thirds as wide as the prothorax, finely and moderately closely punctate, the the eyes prominent ; epistoma abruptly depressed along the apex, the labrum very transverse ; mandibles in great part pale ; an- tenna* long and slender. Prothorax nearly three-fourths wider than long, the sides subpai-allel, strongly and almost evenly arcu- ate ; basal angles very obtuse but not obliterated ; marginal fringe dense, even and distinct ; disk finely and somewhat closely punc- tate, a wide lateral area rugose and abruptly delimited but with- out an impressed line. Elytra short, scarcely one-half longer than wide, barely one-third wider than the prothorax, subparallel and straight at the sides, the apex broadly rounded ; disk finely and rather sparsely punctate, more strongly so toward base. Length 2.7 mm.; width 1.15 ram. California. The example above described has the fifth ventral broadl}' truncate at apex. The legs in this specimen are pale, but in the types of LeConte they are said to be '' nigro-piceis." The transverse and clearly limited bands of pale pubescence on the elytra render this one of the most distinct species of the genus. 14. D. lineelllis n. sp. — Kather stout, strongly conve.x, oblong-oval, black, the legs black; antennte and jialpi black, the former slightly piceous toward base excepting the first joint; pubescence pale luteo-cinereous, coarse, rather long, extremely dense and closely decumbent, without trace of erect hairs, the elytra each with four fine longitudinal dark lines of blackish pubes- cence, the lines somewhat irregular, the second from the suture approaching the humeri toward base and broadly united witli the fourth before the apex, tlie third short and lying midway between" them.

Prothorax scarcely more than one-lialf wider than long, the sides convergent anteriorly and feebly arcnate throngh^ are shorter as a rule than in Dasytes, and are more definitely incrassate toward apex. The six species known to me may be thus defined in brief: — Body uniformly black or piceous-black in color. Elytra! vestiture cinereous throughout. The pubescence short. Head small; sides of the prothorax broadly subexplanate; legs feebly bicolored 1. cataliiiae Head large; sides of the pronotum evenl}^ convex and declivous; legs pale rufo-ferruginous throughout 2. reilliSSUS The pul)escence long, fulvo-cinereous; legs bicolored 8. otiosus Elytral vestiture dark and inconspicuous, becoming paler and coarser to- ward base and at the apex 4. dispar Bwly bicolored, the head and prothorax pale and rufous.

G. 1)icolor In geographical range these species occupy' the same regions as Dasytes, but at present none is known to extend far to the east- wai'd of the Sierra Nevada Mountains. 1. ». catalinae Lee— Proc.

Elongate, suboval, rather convex, polished, black; legs rufous, the femora piceous ; antennae black, piceous toward base ; pubes- cence rather sparse and somewhat short, cinereous, decumbent and completely' devoid of erect hairs. Head about three-fifths as wide as the prothorax, smooth, finely and sparsely punctate, more closely so and slightl}^ rugose toward the sides and base ; epistoma very short, the labrum arcuato-truncate at apex ; eyes small and convex ; antennoe rather short, slender, the penul- timate joints apparentl}' slightly transverse.

Elytra two-fifths longer than wide, scarcely more than one-fourth wider than the prothorax, very slightly wider near api- cal third than at base, the apex somewhat obliquel^y narrowed, then narrowl}' obtuse and rounded ; disk finely, not very densely punctate, strongly so toward base. Length 1.6 mm.; width 0.T5 mm. California (Sta. Catalina Island). The broadly subexplanate sides of the pronotum, small head and color of the legs will ren- der the identification of this small but distinct species alwa3-s easy when the localit}' is known, as it is undoubtedl}' confined to the island. The specimen described above has the fifth ventral broadly truncate at apex and is apparently a male. 2. D. reiiiissus n. sp. — Elongate, strongly convex, moderately shining, black with a piceous tinge, the legs pale ferruginous; antennae piceous, piceo- 584 Goleoplerological Notices, VI. testaceous towaril hase; pubescence luteo-cinereous, moderately lonj^ aiut coarse, not very dense and closely decumhent, not intermixed with erect hairs.

Prothorax two-thirds A\ider than long, the sides sub- parallel, broadly and rather strongly arcuate, somewhat more obviously so to- ward bcase, the edges feebly serrulate; basal angles very broadl}- obtuse; apex and base feebly arcuate and subetjual ; disk evenly and strongly convex from side to side, finely but strongly and rather closely ])unctate, the marginal fringe rather long, dense and conspicuous. Eh/Ira one-half longer than wide, one-fourth wider than the prothorax, the sides subparallel and nearly straight, obliquely convergent behind, the tip narrow, subtransversely truncate and strongly serrulate, not at all dehiscent at apex, the sutiiral angles right and not rounded; disk rather finely but strongly punctate, the punctures somewhat close-set. Under surface thinly clothed with rather long and luteo-cinereous jnibescence. Length 1.9 mm.; width 0.75 mm. California (north of San Francisco). Of this interesting form I have before me three specimens from as many distinct localities; of these only one satisfies the above description, this example having the fifth ventral broadly trun- cate and being without doubt the male. The other two speci- mens have darker legs, the femora in one being blackish, and a broadly and evenly rounded elytral apex ; the head in one of these two specimens is smaller than in the other and both have the fifth ventral more or less evenly and broadly truncate at tip. It is probable that there is some specific difference which cannot be advantageously defined at present. 3. D. otiosiIS n. sp. — Elongate, rather strongly convex, subparallel, strongly shining, the integuments very obsoletelj^ and minutely rugulose^ legs ferruginous, the femora blackish ; antennte piceous-black, testaceous to- ward base, the first joint blackish; pubescence long, subdecumbent, rather coarse, somewhat sparse, pale fulvo-cinereous in color, without erect hairs.

Elytra rather more than one-half longer than wide, nearly one-half wider than the prothorax, scarcely visibly Avider behind than at base, the sides subparallel; apex obtuse; disk somewhat coarsely and closely punctate and feebly rugose, the sculpture feeliler toward apex. Under surface shining, feebly pubescent. Length 2.25 mm. ; width 0.9 mm. California, The type and only specimen known to me has the fifth ventral rather short, trapezoidal and truncate, and the genital segment strongly and evenly rounded behind, with the disk perfectly even. I am, however, not certain of the sex of this individual, for the fifth ventral seems to be truncate in both male and female in this section of the genus. 4. D. dispar n. sp. — Somewhat short, strongly convex and subo\al, strongly shining, the integuments feebly reticulato-rugulose, black, the legs ferruginous with the thighs darker; antenna- black, piceo-testaceous toward base; pubescence rather short and sparse, cinereous toward base and near the apex of the elytra and on the head and pronotum, finer and blackish elsewhere, devoid of erect hairs. Head rather more than three-fourths as wide as the prothorax, moderately transverse, feebly un- even, finely and sparsely punctate, with the frontal impress! ops obsolete; epistoma very short and transverse, the labrum small, transverse, truncate; eyes small but prominent; antennae slender, not quite as long as the head and prothorax, very feebly and gradually inci'assate, the tenth joint a little wider than long, the lifth very slightly dilated. Prothorax fully three-fourths wider than long, the sides subparallel and distinctly arcuate, rather more evidently so toward base, the edges distinctly serrulate; basal angles very obtuse but not obliterated, the ai)ical obtuse but distinct from above, rounded as usual when viewed sublaterally ; apex slightly narrower than the base, both feebly arcuate; disk finely but strongly, sparsely punctate throughout, the flanks evenly convex and declivous, strongly and narrowly impressed along the lat- eral edges at the basal angles; marginal fringe short but distinct. Elytra very feebly dilated posteriorly, not quite one-half longer than wide, nearly one-half wider than the prothorax, obtusely rounded behind; disk somewhat finely and quite sparsely punctured. Abdomen thinly clothed with short fine and dusky-cinereous hairs. Length 1.75-2.0 ram. ; width 0.75-0.85 mm. California (north of San Francisco). This species is quite isolated, and is represented in my cabinet b}^ four specimens taken in three localities ; these agree very well among themselves, except that in one small example the pale fulvo-cinereous hairs of the elytra spread almost evenly over the entire surface, but under more power the pale hairs near the mid- dle of the elytra are readily seen to be mingled with the more 586 Coleoptei'ological Notices, VI. slender blackish hairs of the same length. I am unable to observe any sexual differences. 5. I>. ruficollis Ulke— Geog. and Geol. Exp. and Surv., 4 to., Wheeler, V, 1875, p. 812 (Dasytes). Stout, oval and strongly convex, polished, piceous, the head, prothorax,and apex and flanks of the el3'tra pale flavo-testaceous ; legs very pale throughout ; antennae blackish-piceous, pale testa- ceous in about basal half; pubescence short, even, pale cinereous, moderately dense and distinct, without trace of erect hairs.

Under surface slightly pubescent, the hind femora some- what piceous in color. Length 1.75-1.9 mm. ; width 0.75-0.9 mm. California (Los Angeles Co.). The fifth ventral of the individual described is trapezoidal and rather broadly truncate at apex. This species differs greatl}^ from rujicollis in its minute sparse punctuation of the anterior parts, form of the prothorax, pubescence and numerous other features. The two specimens in my cabinet are mutuall}' similar through- out. ESCHATOCREPIS Lee. In this genus the ungual appendages are equal, rather slender, well developed and as long as the claws, but are clearly detached from them except near the base ; in other respects Eschatocrepis is allied to Listromimus, but differs in the form of the epipleurae, which are nari'ow and horizontal, with the plane gradually turned upward and inward posteriori}'. The anterior tibije are C3'lin- drical and devoid of all trace of spinules along the external side, and the eyes are large and basal, the antenna? rather short and either gradually incrassate or with an abrupt three-jointed club; they are scarcely at all serrate. The pronotum has a deep im- pressed submarginal line in both sexes. 1. E. coiistrictiis Lee. — Proc. Acad. Nat. Sci., Phila., YI, p. 170 ( Da- sytes); Class. Col. N.

Coast regions of California from Humboldt to San Diego. This abundant species seems to be resolvable into two or three closely allied forms, but it would scarcely be worth while to un- dertake the definition of them without very full series from care- fully recorded localities. One form from San Diego is certainly distinct in its much more feeble thoracic constriction, denser pubescence and acute elytral apices ; another from Sta. Barbara is more elongate in the body and more densely pubescent than the typical forms, in which the el^'tral pubescence is relativel}' sparse, dark and inconspicuous. In the male the fifth ventral has a transverse and rectangular apical emargination, with the adjacent surface slightly declivous, and I can perceive little or no variation in this sexual character in the various allied forms alluded to above. ALtOIVYX Lee. The parallel form of the body and structure of the epipleurte will readil}- distinguish the representatives of this genus from the allied forms with similar asymmetric ungual appendages. The epipleura' are wide, flat and subhorizontal throughout, preserving their width almost unaltered to within a short distance of the apex and there terminating somewhat abruptly ; their surface is finely punctured and pubescent, and the side margins of the elytra are correspondingly reflexed. The antenna? are rather short, feebly incrassate and are scarcely at all serrate, the eyes large and basal, the anterior tibiae devoid of spinules, the maxillar}^ palpi somewhat stout and pale in color, and the vestiture very feebl}^ developed. The prothorax is not at all constricted near the apex, and the pronotum has at each side a strong excavated line parallel to and at some distance from the lateral edge, the intermediate surface being broadly subexplanate but only a little more strongly sculptured than the median parts of the disk. J Coleopterological Notices, VI. 589 The materiul in my cabinet seems to indicate the three follow- ing species : — Submarginal line of the pronotura entire, extending to the apex.

The single specimen before me is a female, said by Mr. Dunn to have been taken b}' him in the vicinity of San Fran- cisco ; it is a female, as proved by the extruded genitalia, but the 590 Coleopterological Notices, VI. fifth ventral is tlattcned and rectilinearly and broadly truncate at apex, the genital segment being broadly bilobed and deei)ly iia- presso-canaliculate along the middle. 2.

Prolhora.r three-fifths wider than its median length, the sides parallel, feebly and almost evenly arcuate, straight toward the basal angles, which are obtuse but not rounded and not in the least prominent; apical angles right and slightly blunt, apex almost rectilinearly truncate throughout the width, the base vrith a very abrupt and broad arcuate median lobe; disk finely and feebly granulato- reticulate, smooth and alutaeeous, slightly rougher between the submarginal line and the side margin, the latter feebly reflexed as usual ; punctures toward the middle extremely minute and sparse but abrupt and distinct under sufii- cient power. Eli/Ira three-fifths longer than wide, one-fifth wider than the prothorax, parallel and feebly, evenly arcuate at the sides, the apex liroadly rounded and subtruncate, the lateral edges reflexed and the apices subexplan- ate; sutural angles right, not rounded; disk confusedly though feebly and subtrausversely rugose, the punctuation fine and very indistinct. Under sur- face finely but distinctly cinereo-pubescent, the legs well developed. Length 3.3-4.0 mm. ; width 1.25-1.5 mm. California (north of San Francisco). The three examples before me are males, the apex of the fifth ventral being transverse and abruptly and deeply sinuate at the middle, the genital segment being deeply bilobed. In the female the legs are doubtless paler. This species difters from sculptilis in having the sides of the prothorax very feebh' and almost evenly arcuate and not sinuate toward the basal angles, which are obtuse; the apical angles are occasionally feebly prominent anteriorlv. 3. A. disjlinctlis n. sp. — Oblong, subparallel, feebly convex, dull, the elytra shining, the integuments strongly granulato-reticulate, much more ol)- soletely on the elytra; body black tliroughout, the apices of the elytra pale; Coleojoferological Notices, VI. 591 legs pale, the tip of the hind femora but slightly darker above; aiitennaj tes- taceous, the eleventh joint slightly darker; pnbescence cinereous, extremely short, fine, decumbent and sparse, without trace of erect hairs. Head two- thirds as wide as the prothorax, more shining, the sculpture feebler, finely, feebly punetulate, the impressions large and deep, not coalescent behind, the epistoma short; labrum transverseand very broadly rounded; eyes large, prom- inent and basal; antennte one-fourth longer than the prothorax, very feebly incrassate toward apex, the tenth joint evenly triangular, nearly as long as wide, fifth sensibly dilated. Prothorax barely three-fifths wider than long, the sides parallel, evenly and feebly arcuate, becoming slightly sinuate toward the basal angles, which are right and not rounded; apical angles slightly acute, ad- Aanced and not blunt; apex broadly emarginate; base with a very broad and feeble arcuate lobe; disk finely and sparsely but distinctly punctate. Elytra two-thirds longer than wide, one-fourth Avider than the prothorax, very feebly and gradually dilated behind, the apex evenly rounded; lateral edges reflexed; sutural angles acute and posteriorly prominent; disk strongly and rather closely punctate, less distinctly so toward apex. Abdomen polished, somewhat sparsely clothed with short and fine cinereous j)ubescence. Length 3.5 mm. ; width 1.4.'i mm. California,. The type of this species is a female, differing from the female of sculptilis in having the submarginal impressed line of the pronotum abruptly ending at about apical fifth of the length. The fifth ven- tral is truncate as in sculptilis. VECTURA n. gen. In this genus the body is cuneiform, with the head small and more elongate than usual, the antennae being moderate in length, scarcely serrate and feebly incrassate at apex, the eyes situated before the base of the head and slightly elongate, and the pro- thorax more or less constricted near the apex, with the basal an- gles acute and prominent. It resembles Allonyx to some extent in the form of the epipleuri^, these being rather wide, flat, subhor- izontal and pubescent, but, unlike those of Allonyx, becoming gradually narrow behind the middle. The inner claw has a very long and rather thick corneous expansion and the membranous appendage is correspondingly shortened but extends to the tip of the claw. The tibia* are devoid of spinules as usual in this group. The two species known to me may be distinguished as follows : — Pubescence not entirely concealing the integuments; ])rothorax strongly con- stricted behind the apiciil angles, which are very acute and prominent later- ally 1. loiigiceps 592 Coleoi^terolofjical Notices, VI. Pubescence extremely dense, completely concealing the integuments; protho- rax very broadly and oljsoletely constricted near the apex, the angles later- ally obtuse, rounded and scarcely at all prominent 2. allucans In geographical range Vectura is i)robably limited to the great arid and elevated internal basin region, between the Sierra Nevada and Rocky mountains. 1. V. loiigiceps n. sp. — Broad and strongly dilated behind, cuneiform, moderately convex, feebly shining, pale ochreo-testaceous throughout, the metasternum, maxillary palpi and antenna; toward tip blackish ; pubescence closely appressed, dense, yellowish-white, the hairs broad and squamiform, without trace of erect hairs; marginal fringe composed of short dense and pos- teriorly inclined white hairs. Head small, elongate, three-fifths as wide as the prothorax, flat, Avith indistinct sparse punctules, the impressions very feeble; epistoma transverse but well developed, the labrum large, broadly arcuate at tip ; eyes elongate-elliptical, feebly convex and not attaining the base; antennae but feebly serrate, one-fourth longer than the prothorax, the fifth and seventh joints much larger than the sixth or eighth, last three joints larger, the penultimate slightly transverse. Frothorax one-fourth wider than long, the sides feebly convergent from the base, feebly arcuate, slightly and broadly sinuate near the base, deeply constricted behind the apical angles which are laterally acute and very in'ominent; basal angles slightly acute, everted and prominent; apex arcuate, narrower than the base, which is broadly and arcuately lobed; lateral edges finely serrulate; disk finely, feebly and rather closely but indistinctly punctate, the submarginal excavated line ex- tending only to apical fourth. Elytra three-fifths longer than wide, oval, gradually w ider to apical two-fifths, where they are more than twice as wide as the prothorax; sides evenly and feebly arcuate; apex acutely ogival, the sutural angles minutely acute and posteriorly prominent; lateral edges nar- rowly reflexed; humeri exposed and transversely rounded; disk finely )mt strongly, distinctly and closely punctured, the interspaces shining. Under surface densely clothed with appressed white pubescence, the legs very slender and moderately long. Length 3.6 mm. ; width 1.55 mm. Arizona (Yuma). Mr. Dunn. The typical specimen described above is a female, having the fifth ventral rounded behind, with the disk feebly impressed in the middle at the apex. I have before me two females not mutu- ally differing at all in structure. 2. V. albicans n. sp. — Stout, moderately dilated posteriorly, strongly con- vex, the surface completely concealed by a dense even coat of rather long and closely appressed, stout and snl)S(iuamiform white hairs, without trace of in- termixed seta? except the usual few erect black hairs near the abdominal apex; marginal fringe composed of short, dense and decumbent white hairs; body black, the elytra and legs pale testaceous throvighout; antennic tastiiceous, bhickish toward tip. Hmd scarcely two-thirds as wide as the prothorax, a Coleojiterological Notices^ VI. 593 little longer than wide, not greatly prolonged before the eyes, .the latter liow- ever small, prominent, slightly elongate and at a considerable distance from the base, the neck subparallel behind them ; surface flat, the integument com- pletely concealed, the frontal impressions apical and feeble; labrum and apex of the epistoma pale testaceous, the palpi black; antennae scarcely a third longer than the prothorax, the outer joints larger, the penultimate slightly transverse, the sixth and eighth small. Prothorax one-fourth wider than long, the sides rounded and feebly prominent behind the middle, thence strongly convergent and In'oadly sinuate to the apical angles which are laterally obtuse, and feebly convergent and straight to the basal angles which are acute and slightly prominent; apex arcuate, much narrower than the base which is broadly and arcuately lobed; disk convex, completely concealed by the vesti- ture except the excavated submarginal line, which does not attain the apex or base. Elytra large, two-thirds longer than wide, gradually wider posteriorly, and, at apical third, twice as wide as the prothorax ; apex acutely ogival, the sutural angles slightly obtuse; humeri exposed at base; lateral edges nar- rowly reflexed. Under surface clothed with an extremely dense crust of white decumbent pubescence, the legs rather short but slender. Length 3.25 mm.; width 1.5 mm. Utah (southwestern). Mr. Weidt. Both of the specimens before me seem to be females, the fifth ventral segment being strongly rounded at apex. This species differs from the preceding in its denser coating of pubescence, shorter but broader head and other characters. PSEUD ALLONYX n. gen. This genus resembles Allonj^x in the structure of the tarsal claws and nngual appendages, but the inner claw is distinctly smaller than the outer and more abruptl}- bent at apex, and its appendage is larger and thicker and closely adherent to the claw almost throughout its length ; the appendage of the outer claw is small and altogether basal. It difters greatly from Allonj^x in the form of the body, and in having the wide flat punctate and horizontal epipleurje gradually inflexed upward in plane toward apex. In the structure of the eyes, antennjB and tibi» it agrees in general with Allonyx. I know of but one species at present. 1. Ps. plumbeus Lee— Proc. Acad. Nat. Sci., Phila., 18G6, p. 359 (Al- lonyx). Cuneiform, moderately convex, opaque, the elytra a little less densely so, black ; legs pale rufo-ferruginous throughout ; pubes- cence not ver}' coarse, appressed, white and rather long, some- what dense on the elytra, sparse anteriorly ; erect hairs entirely 594 Coleopterological Notices^ VI, wanting, the marginal fringe very short dense and posteriorly de- cumbent. Head small, scarcely more than three-fifths as wide as the prothorax, smootlier and finely, sparsel}' punctate toward the middle, the impressions large but feeble ; epistoma rather long, pale, the labrum pale and strongly rounded ; eyes moderately large, strongly convex ; antennae rather slender, feebl}^ serrate, one-fourth longer than the prothorax, pale testaceous, darker toward tip, the last three joints larger and blacker, the penulti- mate joints transverse. Prothorax two-fifths wider than long, widest and rather narrowly rounded just behind the middle, the sides distinct^ convergent and straight or just visibly sinuate to apex and base, the basal angles slightly obtuse but not in the least rounded and apparently somewhat prominent ; apex arcuato- truncate, much narrower than the base, the latter broadly arcu- ate, obliquely sinuate lateralh^ ; disk densely' and finely punctato- rugose, obsoletely and sparsely punctate, the submarginal exca- vated line not extending to the apex. Elytra three-fifths longer than wide, gradually wider to about apical third, where they are nearly twice as wide as the prothorax, the apex thence obtusely' ogival ; lateral edges narrowly- reflexed ; humeri exposed at base and rounded ; disk obliquely and broadly impi'essed near the base, finely and somewhat closely punctate. Under surface albido- pubescent. Length 3.0 mm.; width 1.4 mm. Colorado and Arizona. The individual described above is a female, and the fifth ventral is broadly rounded behind. The male is undoubtedly narrower and less dilated behind. The apex of the elytra and the lateral edges to a slight degree posteriorly are rufous or rufescent. LEPTOVECTIRA n. gen. Although evidentl}- belonging to the well defined Allonyx group of the tribe by reason of thoracic and ungual structure, the single type of this genus ditfers greatly in general appearance from any of the others in its Listrus-like body, with the elytral epipleuraj narrow and gradually disappearing posteriorly in a fine line on the external tlank very near the edge as in Das^'tes. The inner claw has a ver^' large lamelliform appendage, which is ap- parently closely affixed throughout its length, the outer being simply obtusely swollen or subdentate internall}' at base. CoIeopte7^ological Notices, VI. 595 1. Li. adspersa n. sp. — Elongate, narrowly oval and not broader behind, strongly convex, black, the legs pale testaceous, the femora infuscate above to- ward apex; antennte pale, dark near the tip; pubescence moderately dense, composed of closely appressed and rather long broad hairs, which are white and dark brown in color confusedly intermingled throughout, becoming denser and white near the sides and along the base of the pronotum, and altogether white though scarcely denser on the head; soutellum covered with a dense mass of white pubescence; marginal fringe composed of very short, dense and coarse, posteriorly subdecumbent brown hairs. Head two-thirds as wide as the jDrothorax, fully as wide as long, flat, obscurely and finely punctate, the impressions apical and feeble; epistoma pale and well developed, the labrum pale, broadly rounded at apex ; eyes small, prominent, at some distance from the base, the neck slightly constricted; antennse rather long and slender, much longer than the prothorax, the joints ol)lique at apex, fifth elongate and slightly dilated, the three last slightly larger, the penultimate nearly as long as wide, sixth and eighth slightly smaller. Prothorax two-fifths wider than long, not constricted, widest and subi)rominentIy rounded just behind the middle, the sides strongly convergent and straight to the apical angles, which are obtuse but not blunt from above, and almost equally convergent and straight to the basal angles, these being acute, everted and minutely prominent; apex arcu- ato-truncate, narrower than the base which is broadly and arcuately lobed; disk finely, rather closely punctate, the submarginal groove very coarsely ex- cavated, extending almost to the apex and curving inward near the base, be- coming obsolete toward the middle. Elytra elongate, nearly twice as long as wide, slightly wider than the prothorax, the sides parallel and feebly arcuate, obli(juely convergent and arcuate at apex, the immediate tip rather narrowly obtuse; sutural angles acute; punctures fine and moderately close, not very distinct; margins not at all reflexed. Under surface densely clothed with de- cumbent white pubescence, which is especially dense on the met-episterna and abdomen; legs rather stout. Length 3.0 mm. ; width 1.0 mm. New^ Mexico. The fifth ventral segment in the single type before me is strongly rounded at apex. This striking species can be at once identified by its elongate elytra, variegated vestiture and thoracic structure. MECOMYCTER Horn. In this genus the ungual appendages become completel}^ obso- lete, the claws being at the same time unusually slender and with a small internal enlargement at base. The epipleurre are subhori- zontal and moderate in width, becoming extinct behind the mid- dle, and the genus further difiers from the members of the Allonyx group, which it resembles to some extent, in having all the tibiae beset externally with a few blackish spinules,aud in the complete Annals N. Y. Acad. 8ci., VIII, Sept., 1895.— 41 596 Goleopterolorjical Notices, VI. absence of a lateral submarginal line on the pronotum. The elon- gate head is not strictly peculiar to Mecomycter, as it exists to a pronounced degree also in Vectura. The two species can be separated thus : — Prothorax elongate, -witliout a lateral projection behind the middle. 1. oiiialiiiiis Prothorax transverse, with a conspicuous projection at the side at Ijasal two- fifths 2. facetus The genus is distributed tlirough the arid regions from Kansas to Arizona. 1. m. oiualiiiuiii Horn— Trans.

Stout, moderately convex, feebly shining, i)ale testaceous in color, the l)ase of the head, maxillary palpi, outer seven joints of the antennffi and entire under surftxce of the hind liody, except the me^osternal side-pieces, black or blackish; elytra black, with the apex and an elongate area from the humerus to apical third of each pale testaceous ; legs pale throughout ; pubescence short, rather sparse, pale in color, the elytra with a few scattered hairs which are slightly longer and more erect ; marginal fringe obso- lete. Head three-fourths as wide as the prothorax and nearly twice as long as wide, flat and coarseh* punctate, the interspaces minutely punctulate ; eyes well developed, distant from the liase, the neck narrowed toward base; antenna? one-third longer than the prothorax, the first two joints stout, the next two slender, the remaining seven larger and feebly incrassate to the apex, the tenth slightly transverse. Prothorax fully as long as wide, the sides evenly convergent and nearly straight from the oblique and slightly sinuate basal angles to the apex, the apical angles obtuse but not rounded from above, the apex truncate, narrower than the base which is broadly and evenly arcuate ; marginal acute line far down on the flanks, very fine, non-serrulate and curving upward in a broad arc toward apex ; disk rather coarsely and rugosely punctate. Elytra scarcely one-half longer than wide, feebly di- lated behind and more than twice as wide as the pro- thorax, evenly and broadly rounded at apex; humeri tumid and l)roadl3' exposed at base ; lateral edges fine and not reflexed ; disk coarsely but not densely, subrugosely punctured toward base, very feebly sculptured toward apex. Legs rather long and slender. Length 3.0 mm.; width 1.2 mm. Goleopterological Xotices, VI. 5 97 Kansas. The specimen described is probably a female, the fifth Tentral being broadly rounded behind. 2. M. facetus n. sjj. — Moderately stout and convex, rather shining, pale testaceous in color, the elytra with a sutural area not attaining the apex and sinuately narrowed hefore the middle of hlack; under surface of the hind body black, the mesosternum and fiftli ventral segment pale; legs pale, the hind thighs infuscate except toward tip; pubescence short, not very dense, pale, rather fine and subdecombent, intermixed on tlie elytra Avith numerous short and more erect hairs of the same color; marginal fringe almost obsolete. Head missing in the type. Profhorax three-fifths wider than long, the sides subparallel, rather acutely prominent at basal two-fifths, thence feebly con- vergent and broadly sinuate to the apical angles which are rounded from above, and slightly convergent and nearly straight for a short distance to the basal angles, these being obtuse but evident; base and apex broadly and al- most ec^ually arcuate, the former very slightly the wider; disk rather coarsely but feebly, sparsely and somewhat inconspicuously punctate, the marginal acute edge fine, rapidly descending far down the flanks from the liase to apical third, then more rapidly and subtransversely ascending in a broad arc. Elytra two-fifths longer than wide, only just visibly wider behind and scarcely two- thirds wider than the prothorax, the sides subparallel and feebly arcuate ; apex obtuse, broadly truncate toward the middle, the sutural angles right; humeri tumid but not very widely exposed at base; disk rather coarsely but feebly, sparsely and inconspicuously punctate toward base, the sculpture becoming- very fine toward apex. Under surface rather thinly clothed with verj' short, fine and subcinereous pubescence, the legs slender. Length ( exclusive of the head) 1.9 mm. ; width 0.95 mm. Arizona? The single specimen, which I found among some discarded ma- terial some years ago, is without any indication of locality, but was in all probabilit3' taken by Mr. Morrison ; it is a male, the fifth ventral being short and broadly truncate, with a small feeble sinuation at the middle of the truncature. I do not think that it could by any possibilit}^ be the male of the preceding species, which is known to me only hy the female. DOLICHOISOMA iSteph. The American type of this genus has no vestige of elytra! epi- pleurse, the lower edge being acute and without a submarginal line even toward base. This peculiarity necessitates its isolation from all other generic groups of the tribe. The tarsal claws are stout and strongly developed, the inner .having a large corneous internal dilatation in basal half, which is 598 Coleojiterological Notices, VI. continued to the apex by the rounded membranous appendage, the latter leaving a small part of the tip of the claw free ; the outer claw has the inner corneous dilatation extending far be3'ond the middle, but the appendage forms merely a membranous ter- minal margin ; the apical portion of the outer claw is more pro- longed and arcuate than the corresponding part of the inner claw. The tibiiB are altogether devoid of external spinules, but are clothed sparsely throughout with long erect and stilt' black hairs, and the pronotum has no trace of a submarginal line. The body is extremely elongate and subcylindrical, differing vcr^' much in facies from an}- other iy\iQ. of the tribe. Two species may be assigned to this genus as follows, fovei- collis serving as the type of the above remarks : — Prothorax one-third wider than long 1 . foveicollis Prothorax nearly twice as long as wide 2. teiiiiiforiuis This genus seems to occur principall}' on the eastern slopes of the Rocky Mountains from Texas to Hudson Bay, but probabl}- entered the American continent by way of Siberia. 1. D. foveicollis Kirby— Fauna Bor. Am., IV, p. 243 (Dasytes); Lee: Proc. Acad. Nat. Sci., Phila., 1866, p. 358 (Dolichosoina). Very elongate, subcylindrical and convex, black with a strong blue "reflection; legs black, the antenui^ black with the second joint, and, to a less degree, the first, testaceous ; pubescence stiff, long, erect and black, very sparse, the hairs of the elytra varying in length ; marginal fringe completely obsolete ; integuments strongly shining. Head five-sixths as wide as the prothorax, wider than long, coarsely and sparsely punctate, convex, with two deep impressions anteriorly which are posteriorly confluent ; sur- face between the antennoe tumid ; epistoma truncate, the labrum broadly rounded ; eyes obliquely oval, not attaining the base, the neck rapidly narrowed behind them ; antennae long, compressed, only feebly serrate, much longer than the head and prothorax, not incrassate toward tip, the joints longer than wide. Prothorax one- third wider than long, the sides subparallel and broadly arcuate, feebly convergent and nearly straight posteriorly, the disk widest before the middle, sparsely and ver}- coarsely punctate and slightly uneven ; base truncate, with the angles somewhat obtuse ; lateral edges very acute. Elytra two and two-thirds times longer than wide, distinctly wider than the prothorax, the sides subparallel Coleopterological Notices, VI. 599 and straight, very gradually oblique and rounded toward apex ; sutural angles obtuse and rounded ; disk not very coarsely but strongly, very sparsely and rugosely punctate, the interspaces shining and minutely, feebl}' rugulose. Under surface very sparsely pubescent, the legs long and slender. Length 6.5 mm.; width 1.4 mm. Nebraska and northward. The male, which is the only sex which I have seen, has a very large and deep anteriorly arcuate excavation at the apex of the fifth ventral, the bottom of the ex- cavation gradually smooth, level, polished and glabrous poste- riorly, with a rectilinear and transverse posterior margin, which is less apical than the lateral lobes of the segment ; the genital seg- ment is broadly sinuate at apex throughout its width, flat, with all but an abruptly limited lateral area pale and subcoriaceous. The allusion to cinereous hairs by LeConte, in referring to the vesti- ture of this species, is altogether erroneous. 2. D. teiiuiformis Horn— Trans. Am. Ent. Soc, VIII, 1880, p. 150. The body in this species is extremel}^ slender and elongate, dark greenish-bronze in color and subopaque above, bluish and shining beneath. Head coarsely punctured, the front triangularly im- pressed. Prothorax a little narrower than the head, nearly twice as long as wide, with the sides parallel ; disk with an impressed median line. Elytra a little wider than the prothorax with the sides straight, nearly three times as long as the head and pro- thorax, the disk rather coarsely, densely and irregularly punctate, the sutural margin slightly elevated. licnth 4 mm.

This species somewhat resembles the European D. linearis in form, according to Dr. Horn ; I have seen no representative, and the above statements are taken from the original description. Melyrini. This tribe is but poorly represented in the United States by a single small genus on each side of the continent. There can be no doubt at all that both of these genera are ditferent from the Euro- pean Melyris,and I have therefore thought best to give them sepa- rate names; the}' are mutually ver}' distinct themselves, and may be known b}' the following characters : — 600 Goleopterological Notices, VI.

ALYMERIS n. gen. This genus consists of small or moderate sized species, having the integuments very coarsely, deeply and closely cribrate and the epipleurffi rather wide, with their plane inclined slightl}' upward and almost equal in width from the base to the sutural angles, differing radicall}' in this respect from any other genus of the family inhabiting the United States ; the eplpleurae are flat and flnel}' punctate, and the margins become prominent toward apex, the lower edge being strongly serrulate. The antennae are short, the maxillary palpi somewhat small in size, the eyes well developed and convex, the sides of the pronotum serrulate, the anterior tibite devoid of spinules and the tarsi rather short, with the basal joint quite distinctly shorter than the second, and the fifth joint of the posterior fully as long as the three preceding together ; the ungues are slender, with a feeble dentiform internal dilatation at base, the appendages being obsolete. We have three well defined species as follows : — Elytra dark castaneous, the base and a small spot at tlie middle of each near the apex pale testaceous; pubescence inconspicuous 1. basalis Elytra uniform in color, blackish or ijiceous. Elytral pubescence inconspicuous; prothorax strongly transverse and rap- idly narrowed toward apex 2. cribrata Elytral pubescence long and distinct; prothorax much less transverse and feebly narrowed toward apex 3. Iloridaiia The species of Alymeris are confined to the Atlantic and Gulf regions of the continent from New York to Louisiana. 1. A basalis Lee. — Proc. Acad. Nat. 8ci., Pliila., A'l, p. 171 (Dasytes); Class. Col. N. A.., l^Cil, p. 93 (Melyris). Elongate-oval, rather stout, strongly- convex, opaque, black, the elytra castaneous with the base and a subapical spot testa- ceous; legs piceous-black ; antennae piceous, testaceous near the base; pubescence extremel^y short, sparse and scarcely distinct. Coleopterological Notices, VI. 601 Head strongly cleflexed, coarsely relate, the frontal impressions feeble; eyes convex, basal; epistoma with a pale subcoriaceous prolongation, the labrum small, blackish, strongly rounded ; an- tennae scarcely as long as the prothorax, feebly incrassate, the penultimate joints slightly transverse. Prothorax one-half wider than long, the sides broadly arcuate, more convergent anteriorly ; disk opaque and coarsely retate, subexplanate near the lateral edges. Elytra three-fourths longer than wide, distinctly wider than the prothorax, the sides parallel and broadly arcuate, gradu- ally and strongly rounded behind ; disk very coarsely and closely cribrate, with faint vestiges of two or three uneven costuliform lines on each. Length 3.3-3.6 mm.; width 1.4 mm. Georgia to Louisiana. The feeble costuliform lines on the el^'tra are especially evident in the male, in which sex the fifth ventral is broadly deflexed toward tip, with the apex somewhat sinuate in the middle, and the genital segment thin, pale and cori- aceous with its apex broadly and feebly sinuate, and its surface nar- rowly and abruptly carinate along the middle. The description is drawn from the female, and in the other sex the prothorax is less transverse and less narrowed anteriorly, and the elytra rela- tively shorter and more obtuse behind. Two specimens. 2. A. cribrata Lee. — Proc. Acad. Nat. Sci., Phila., VI, p. 171 (Dasytes) ; Class. Col. N. A., 1861, p. 93 (Melyris).

Length 2.2-2.6 mni.; width 0.8-LO mm. Middle and Southern States. This species is not rare, and may be distinguished readily by the characters given in the table. In the male the shining surface of the fifth ventral is gradually de- flexed toward tip, the latter truncate ; the genital segment is small and has a strong median carina. ■i.

The male, serving as the type, has the fifth ventral ver}- short, notdeflexed and broadly truncate at apex, with a rounded shallow siuuation at the middle, the genital segment large and wide, feebly arcuato-truneate throughout at apex and with a transverse ab- rupt and flat-topped elevation on the surface at apex, the anterior margin of which is arcuate and coincident in size and curvature with the median sinus of the fifth segment, these characters be- ing quite different from those of the two preceding species. In the female the bod^' is still more strongly cuneiform, the elytra longer, paler and more oval, the head and prothorax smaller, and the fifth ventral short, fiat and broadly rounded. Two specimens. ErRELYHIS n. gen. The representatives of this genus differ very radically from Alymeris in several particulars. The epipleuraj are very narrow and graduall}'' become extinct far before the apex of the elytra; the tarsi are long, filiform and very slender, with the basal joint onl^- slightly shorter than the second and the latter fully as long as the fifth. The antennte are better developed and are strongly' serrate toward apex, and, finally, the fourth joint of the maxillary palpi isobliquel}' truncate at apex, thus leading feebly toward the next subfamily. The e^'es are lai'ge, prominent and basal , rounded and with a small feeble anterior sinuation, but are glal)rous and not distincth' less finely faceted than usual. The sculj)ture of the bod^' is much finer and sparser than in the preceding genus, but the lateral edges of the prothorax are quite as distinctly serrulate, the edges of the elytra, however, being almost perfectly even throughout. In one of the sexes there is, in all the 8j)ecies,an el- Coleojjterological Notices, VI. 603 liptical area on each elytron near the apex which is polished and impunctate, and of which there is no trace in the other ; in neither sex is there any trace of costnliform lines on the elytra. The species appear to be local and rare, and are distribnted over the dr}' regions of the great interior basin west of the Rocky Mountains ; the three known to me may be known as follows : — Legs black, more or less paler distally. Prothorax widest at or very near the base ; the sides convergent and feebly arcuate throughout 1. speciilifer Prothorax more arcuate at the sides toward base, and widest at a short distance behiud the middle 2. atra Legs pale flavo-testaceous throughout 3. flaTipes In general appearance these species are remarkably homoge- neous among themselves. 1. Eu. speciilifer n. sp. — Oblong, stoiit and strongly convex, dull, the elytra shining ; under surface polished; body deep black throughout, the legs black with the tibiae and tarsi gradually paler; antennje blackish, i^ale toward base; pubescence very sparse, decumbent, moderate in length, dark in color and entirely inconspicuous. Head small, about one-half as wide as the prothorax, the sculpture shallow but scabro-puuctate, smooth toward apex ; occiput feebly impressed along the middle, the frontal impressions obsolete; epistoma short and wide, with a fine pale coriaceous margin; labrum short and very broad, transversely rounded, rather dark in color; ej^es moderately large; antennae a little longer than the prothorax, the two basal joints slightly stout, the next two narrow, the fifth wider, six to ten still wider, rather com- pact, strongly transverse, forming a broad pubescent and serrate club, the eleventh moderate in length. Prothorax two-thirds wider than long, trape- zoidal, the sides strongly convergent from base to ajjex and feebly, almost evenly arcuate, the apex arcuate ; apical angles rounded, the basal obtuse; disk densely and coarsely l)ut shallowly sculptured, the large umbilicate punc- tures connected by anastomosing raised lines, forming still larger polygonal meshes, the sculpture l)ut slightly stronger toward the sides. Elytra nearly three-fourths longer than wide, distinctly wider than the prothorax, the sides parallel and nearly straight; apex obtuse, the sutural angles broadly rounded; disk sparsely punctate, the punctures gradually coarse toward base, fine pos- teriorly, becoming denser and rugulose very near the apex. Abdomen feebly punctulate, finely and sparsely pubescent, the legs rather long and .slender. Length 4.25-4.4 mm.; width 1. 7.5-1. H5 mm. Utah (southwestern). Mr. C. J. Weidt. The type is a male, and in that sex the fifth ventral is mnch longer than the fourth and very broadh' and feebly sinuate to- ward the middle of the apex. In the female the form throughout is similar, but each elytron has an oval, subapical, polished and fi04 Goleopterological Notices, VI. more convex spot, and the fifth ventrnl has a veiy small circu- larly rounded median nick, the genital segment being flexed up- ward in plane, with a large triangular apical emargination. Other than the median nick, the fifth ventral of the assumed female is rounded behind, and, as the antennoe seem to be more slender and the body larger in this specimen, — having the subapical mirrors — it is probable that Dr. LeConte was correct in his iden- tification of the sexes. Two specimens. 2. En. atra Lee— Bull. U. S. Geol. and Geog. Snrv., 1H78, IV, p. 461 (Melyris). There is no representative before me of either this species or the next, but from some drawings and notes made from the orig- inal types a few 3'ears since, it is apparent that atra is nearly identical in sculpture and pubescence to sjiecuHfer and JiavipeSy but is rather narrower, more parallel and straighter at the sides and a little more depressed ; legs as in speculifer. It differs de- cidedly from both in the shape of the prothorax, which is more rounded at the sides and widest at a much greater distance from the base. Length 3.7 mm.; width 1.5 rnm. Colorado (Beaver Brook— 6000 ft.),— Cab. LeConte. The female is the onl}^ sex known. 3. Ell. flaTipes Lee— Bull. U. S. Geol. and Geog. Surv., 1878, IV, p. 461 (Melyris). This species exactly resembles ^ipecidifer, but is smaller and with the legs pale flavate throughout and a little shorter. The hind tarsi are very nearl}^ as long as the tibiie. In sculpture and vestiture it is similar to sjyeculifer, except that the minute retic- ulations of the elytra are more obliterated. Length 3.4-3.8 mm.; width 1.3-1.6 mm. California, — Cab. LeConte. This species probably does not extend westward beyond the Sierras. Rhadalin.e. leilAD Al.rS Lee. In this genus the body is larger than in the preceding subfam- ily, and clothed with long bristling pubescence. The ungual ap- pendages are slender, equal, not as long as the claws and wholly Goleoptei-ological Notices, VI. 605 detached from them except at base, the tarsi moderate in length, with the first and second joints eqnal, clothed with long erect hairs above and long dense and coarse hairs beneath, and the an- terior tibiae have a few long slender external spines. The maxil- lary palpi are long, with the last joint large and in the form of a right-angled triangle, abont twice as long as wide, the terminal joint of the labial palpi being moderately dilated and transversely trnncate at apex. The antennae are long, serrate, with the joints elongate and acutely pointed internally at apex, and the eyes are large, entire, sparsely setose and with the facets very large and convex. The epistoma is large, bisinuate at base, coriaceous at apex, and the labrum strongly transverse, arcuately truncate at tip and with the surface somewhat impressed at the apex. The epipleurre are moderate in width, flat and horizontal, with the plane gradually inflexed posteriorly-, not attaining the apex of the elytra. The two species may be distinguished as follows : — Eyes separated on tlie front by much less than twice their own width ; pro- thorax very mucli narrower than the elytra 1 . testaceus Eyes very much smaller, separated on the front by nearly three times their own width ; prothorax almost as wide as the elytra 2. lecoiitei The punctures of the head and pronotum are coarse, irregular, sparse and unevenly distributed, and each is e;j;cavated in the summit of an elevated tubercle, this form being evidently evolved gradually from the asperate puncture, having its anterior margin elevated. This genus seems to be confined largely to the desert regions of southern Arizona. 1. R. testaceus Lee— Ann. Lye. Nat. Hist., N. Y., V, p. 212. Elongate, subparallel, strongly convex, pale brown in color, the antennae, legs and under surface, except the sterna, still paler and more flavate ; integuments shining and smooth between the punctures ; pubescence very long, erect, pale yellowish in color, rather sparse but very conspicuous on every part of the body and legs. Head only slightly narrower than the prothorax, blackish at base ; antennae very slender, not incrassate, about one-half as long as the body. Prothorax transversely elliptical, fully three-fourths Avider than long, the sides parallel and evenly, strongly arcuate ; disk evenly convex, very sparsely and coarsely punctate. Elytra nearly twice as long as wide and about one- 606 Coleopterolofjical Notices, VI. half wider than the prothornx, parallel, evenly ronnded behind, rather coarsely, evenly and sparselj' perforato-punctate. Length 5.8 mm.; width 2.2 mm. Arizona, — Cab. LeConte. The specimen described seems to be a female, the fifth ventral lieing evenly- and liroadlv ronnded be- hind, the genital segment thin, flat, coriaceous and almost circu- larly rounded. "J. K. lecoiitei n. sp. — Oblong-oval, stout and strongly convex, soine- ■\vliat shining, pale castaneons in color, the legs and antennae throughout paler and more flavate; pubescence pale, sparse but very long, erect and bristling from every part, with some shorter and more decumlient hairs of the saiiie color. Head wider than long, three-fourths as wide as the prothorax, the eyes at some distance from the base; antennie slender, gradually attenuate toward apex, not two-fifths as long as the body, the Joints elongate, the second much the smallest. Prothorax three-fourths wider than long, almost evenly ellip- tical, the sides parallel, evenly and strongly arcuate, and the angles all broadly rounded and obsolete; apex and base arcuate; lateral edges finely serridate; disk evenly convex, coarsely and irregularly punctate, the punctures dense in parts. Etytra three-fourths longer than wide, slightly Avider than the pro- thorax, parallel and straight at the sides, the apex evenly rounded; sutural angles right and not in the least blunt; side margins finely reflexed, the con- cavity with a single series of more pronounced punctures; disk very coarsely and deeply perforato-punctate, the punctures uneven in size and separated by but little more than their own widths. Abdomen finely, sparsely punctulate, the legs long and moderately slender. Length 5.8 mm. ; width 2.5 mm. Arizona (Benson). Mr. Dunn. The single tj'pe before me is evidently' a female, the fifth ven- tral being flat and ver^^ evenly- rounded behind. This species dif- fers from testaceus in its stouter form, relativel}' much larger prothorax, smaller head with very much smaller e^^es, and in its closer and coarser punctuation. Since this revision of the Mel^-ridtie was written, I have received a tolerably complete set of the European genera, and find that there is in general but little affinity with our representatives of the famil}', tlie. American species being smaller, duller and much less conspicuous insects as a rule. The American Dasytes and Dolichosoma are evidentl}- congeneric with the European, or at an}' rate very closely allied, but all our other genera, including Alymeris and Eurelymis, are widely difterent from their most closel}'^ related European analogues. Coleopterological Notices, VI. 607 SCARAB.EID.E. P01.1PH1LI.A Harris. The species described below is one of the fillies of decinilineata. P. paciiica n. sp. — Obloug-oval, convex, piceoiis-blaek, the prothorax pale and bright red-hvown; sterna pale, the abdomen blackish with the pos- terior half of the fourth and the entire fifth segment red; femora pale rufons, the tibise and tarsi darker; vestiture much sparser than in decimlineata but al- most similarly disposed and colored, the yellow scales extremely large and broad and the oblique white humeral vitta very narrow and rather short, the submarginal stripe beginning at some distance behind the humeri; pygidium very sparsely clothed, having large broad sciittered yellowish scales inter- mingled with fine sparse hairs, almost completely glabrous toward apex and deeply impressed in the middle near the base. Head less than one-half as wide as the prothorax, the clypeus truncate with obtuse angles, broadly arcuate toward the middle; punctures deep and well separated; antenna! club nearly three-fifths as long as the entire stem. Prothorax quite distinctly more than twice as wide as long, broadly subangulate at the sides Just behind the middle, the apex slightly more than two-thirds as wide as the base; disk coarsely and very sparsely punctate, finely, densely so and covered densely with white scales along the impressed median line and in a small discal spot at lateral fifth and just behind the middle. Elytra one-half longer than wide, two-fifths wider than the prothorax, the sides parallel and rather strongly arcuate. Length 25.0 mm. ; width 13.6 mm. California. This species differs from deciinlineata in coloration, in its smaller size and rather stouter form, sparser and very much broader scales, very much shorter, broader and more sparsely clothed P3'gidium, shorter and stouter hind femora and numerous other features. It is represented by a single female from the Levette cabinet. THYCE Lee. The following species differs widely from any other thus far discovered in the form of the prothorax : — T. pistoria n. sp. — Stout, oval and convex, pale lirownish-testaceous throughout, the vestiture short, white and very dense, the hairs slightly stout but not at all s(|uamiform, denser near tbe sides of the pronotum and ex- tremely dense (m the scutellum, slightly denser on the pygidium than on the elytra, intermingled on the head and pronotum with numerous fine erect and pale silky hairs, the latter extremely long and dense beneath throughout the extent of the sterna; abdomen uniformly clothed like the elytra but sparsely .so along the middle, especially near the apex. Head scarcely more than two- fifths as wide as the prothorax, the clypeus broadly arcuato-truncate and feebly €08 Col€opterolo(jical Notices, VI. reflexed at apex, the angles broadly obtuse and rounded; antennal club well developed and as long as the first four joints of the stem, the fourth palpal joint twice as long as wide, oblicjuely pointed, excavated as usual and just one-half as long as the antennal club. Prothova.c scarcely more than one-half wider than long, the apex not more than two-thirds as wide as the base, the sides strongly' convergent and only very feebly ai'cuate from base to apex, just visibly more prominent a little before the middle; apex feebly emarginate; base strongly and arcuately lobed in the middle, the basal angles rounded; disk rather finely, indistinctly and densely punctate. Elytra but slightly longer than wide and nearly one-half wider than the prothorax, the sides parallel and somewhat strongly arcuate ; disk feebly and not very densely i)unctate. Pygi- dium three-fifths wider than long, moderatelj' convex. Abdominal segments connate, the fifth alone free as usual. Length 19.0 mm.; width 10.5 mm. California (Los Angeles). Mr. River.s. This species maj- be distinguished at once by the outline and size of the prothorax, the sides being straighter and more con- vergent from base to apex than in an}- other known to me. I have before me onl^y a single male, another perfectly similar speci- men being at present in the cabinet of Mr. Rivers. T. riversin. sp. — Olilong-oval, convex, somewhat shining, pale brownish- testaceous throughout, the knees minutely blackish; body clothed rather sparsely with fine decumlient yellowish hairs, denser along the median line and toward the sides of the pronotum; head, pronotum, sterna and femora clothed in addition with long erect and conspicuous yellowish pile. Head much less than one-half as wide as the prothorax, the clypeus narrowed at Ijase, strongly concave, broadly arcuato-truncate at apex with the angles blunt and rounded; antennie well developed, the club almost as long as the stem; fourth palpal joint rather small, excavated, two-fifths as long as the antennal club. Prothorax slightly less than twice as wide as long, broadly subangulate at the sides just behind the middle, the angle rounded, the disk at this point much wider than at base; apex two-thirds as wide as the base, broadly, cir- cularly emarginate, the base arcuately lobed in the middle, the angles obtuse but very distinct and only slightly blunt: disk rather coarsely deeply closely and distinctly punctate. Elytra nearly one-fourth longer than wide, fully two-fifths wider than the prothorax ; sides parallel, somewhat arcuate toward apex, the latter very broadly arcuato-truncate; disk somewhat coai'sely, sparsely, unevenlj^ and rather feeljly punctate, the sculpture finer and denser along the suture. Pygidium feebly transverse, moderately convex, rather finely but subrugosely punctate, sparsely pul)escent, subglabrous near the apex. Length 20.0-23.0 nun.; width 10.0-12.0 mm. California (Los Angeles). The description given above is drawn from the male, and the female, judging from a specimen before me, is larger, wnth the vestiture rather dense, the antennal club being oval and but Col eopl etiological Notices, VI. 609 slightly move than twice as long as wide. In one respect riversi differs from all the other members of this genus, the female being more densely and conspicuoiislj^ clothed than the male ; it is pos- sible, however, in spite of general facies, that this female does not really belong to the same species, especially' as the basal angles of the prothorax are broadly rounded. The hairs are much finer than usual. The two examples in my cabinet were kindly communicated by Mr! J. J. Rivers, who possesses a considerable series. These species should Ijoth be placed between ca^yenteri and squamicoUis in the table previously published b}- me (Col. Not. I, p. no). It is impossible to properly associate the males and females in this genus unless they be collected at the same time and place, and it is consequently seldom prudent to base a species upon the female alone. XYLORYCTES Hope. X. fauiius n. sp. — Moderately stout, strongly convex, polished, Llack throughout above, dark red-brown beneath, the tibise and tarsi somewhat piceous in tinge; under surface clothed with long brownish-red hair, the upper surface and pygidium glabrous. 31ale — Head less than one-third as wide as the prothorax, the clypeal apex reflexed and bilobed; dorsal horn nearly in satyrus but shorter. Prothorax three-fourths Avider than long, widest near the middle, the sides rounded, strongly convergent, anteriorly; discal declivity beginning at the middle when viewed from above, deep, somewhat excavatetl, it posterior margin prominent but rounded in the middle, its surface covered sparsely with transversely sul)- crescentiform punctures, the posterior elevated surface coarsely and densely punctured anteriorly' at the sides. Elytra nearly as long as wide, equal in width to the prothorax and twice as long, obsoletely striato-punctate. Pygid- ium two and one-half times as Avide as long. Female — Scarcely at all narrower than the male, the head nearly as in safy- rns. Prothorax two-thirds wider than long, evenly convex but feebly im- pressed and more densely and roughly punctured near each apical angle; sides evenly convergent and broadly arcuate from near the base, the basal angles broadly rounded. Elytra very nearly as long as wide, more deeply striate than in the male, the pygidium more canaliculate along the lower margin. Length 28.0-30.0 nun.; width 15.0 mm. Arizona. This species differs from satyrus in its narrower and more ■elongate form. The male differs from the corresponding sex of satyrus in having the vertical wall of the thoracic depression 610 Coleojyterological Notices^ VI. begin at the middle of the length instead of just behind apical third when viewed purpendicularly, and the female differs from the female of that species in its less transverse prothorax, with the sides evenly convergent and rounded throughout and in its relatively longer el^^tra. Three specimens. Satyrus was attracted abundantly to the electric lights at Aus- tin, Texas, in June some years since ; both sexes are quite con- stant in form through a large series. TENEBRIONID^. CONIOIVTIS Esch. The following singular form may be placed near snbpuhescens in the table published by the writer some years ago (Col. Not. II, p. 3Y2j. C gloljllliiia n. sp. — Short and broadly oblong-oval, strongly convex, diall, clothed sparsely -with rather long decumbent yellowish hairs, black, the legs dark piceo-ruf ous ; elytra strongly descending posteriorly in profile. Head a little less than one-half as wide as the prothorax, finely feebly and sparsely punctate, the epistomal sinus moderately deep; antennae about as long as the prothorax, stout, black, pale at apex and toward base.

By certain reflections tlie elytra seem to have each three fine feeble and irregular raised lines in addition to the other sculpture. Six specimens. This species may be placed between viatica and eschschoUzi in the table before mentioned, differing from the former in its coarse sculpture, and from the latter in its much narrower form, polished pronotum and many other characters. The Farallone Islands are about thirty miles from San Francisco and are in deep water. CCELIJS Esch. A revision of this genus, together with a description of the larva of G. ciliatuH, was given in the first part of the present series of papers (p. 1T8), and the classification suggested below si based largely upon the characters there employed. The species of Ccelus are becoming moderately numerous, as the search for them becomes more sj^stemaiic, and the six known to me at present ma}^ be recognized by the following differential statement : — Epistoma deeply sinuate, the sides anteriorly prominent though rounded. Antennal club subquadriarticulate; i^ronotum sparsely and less coarsely punctiite, with large impunctate areas; body very large....grossilS Csy.

Body short and ])road, the elytral asperities smaller, more distinctly de- fined and more isolated; sides of the pi'othorax strongly arcuate; head relatively smaller in size Clirtlllus n. sp. All of the species have long coarse hair well developed along the sides of the body, its function probabl}- being to maintain the spiracles free from sand while burrowing. C. lattlS. — Very broadlj* oblong-elliptical, moderately convex, polished, 'deep black, the legs dark piceo-rufous; palpi and antenniE paler, testaceous, the labrum blackish; pubescence very short, sparse, yellowish, becoming long at the sides of the body, short and very stifl' on the legs. Head not two- ■fifths as wide as the prothorax, coarsely and densely jiuuctured, less closely so 'on the epistoma, subimininctate toward base, the ei)istomal suture marked l)y a deep transverse channel; apical sinuation very broad and feeble; antenna? with the club three-jointed and feeble, the joints strongl.y transverse, the last narrower as usual. Prothorax distinctly more than twice as wide as long; apex one-half as wide as the base and deeply emarginate, the angles narrowly xounded; sides strongly convergent from the base, arcuate, more strongly so at "base, the basal angles obliterated; base transverse and almost rectilinear throughout, with the usual fine coriaceous margin; disk coarsely deeply and conspicuously punctate, the punctures generally rather close-set but uneven in •distribution. Elytra barely as long as wide, about twice as long as the pro- thorax, coarsely asperate and polished. Length 7.7 mm. ; width 4.8 mm. California (San Diego). At first sight this species might be mistaken for globosus, but may be readily distinguished l)y its ver}' much more broadly rounded form and very shallow epistomal sinus. C. ciirtiillis. — Broad and oblong-oval, convex, polished, the elytra dull toward apex, ))lack, the under surface and legs dark rufo-piceous, the trophi and antcnntc still paler and rufous; surface glabrous except posteriorly and at the sides of the body. Head rather small, barely two-fifths as wide as the pro- thorax, roughly sculptured, the epistoma smoother, the suture deep; apical sinus broad and feeble but stronger than in ciliatus ; labrum feeblj- sinuato- truncate at apex. Prothorax short and transverse, slightly more than twice as wide as its greatest length, the apex more than one-half as wide as the base; i Coleopterological Notices, VI. 613 sides strongly arcuate ; disk ratlier finely bnt strongly, sparsely punctate, more densely so and somewhat scabrous toward the sides. Elytra short, not quite as long as wide, equal in width to the prothorax, broadly rounded behind, the asperities moderate in size, feeble toward base, closer and stronger toward apex. Length 5.5 mm. ; width 3.4 mm. California (San Francisco). In ciliatus the prothorax is less strongly narrowed from base to apex, not more than twice as wide as its maximum length and is scarcely more than twice as wide as the head, and the elytra are much more densely asperate. The proportions of the typical ciliatus are 6.5 by 3.8 ram. I have carefully collected large colo- nies of ciliatus, and believe that there are several forms which are at least racial or varietal, some localities jdelding specimens of a very much larger average size than others, with differences in color, relative size of the head, sculpture and other minor fea- tures. EUSATTl'S Lee. The following species is allied to duhius Lee, differing in its smaller size and dull integuments : — Ell. nanus u. sp. — Oblong-oval, strongly convex, dull, the pronotum more shining and simply alutaceous, deep black, the antenna?, labrum, trophi and tarsi dark rufous, subglabrous, each puncture bearing a very small de- cumbent hair more noticeable near the sides of the pronotum, the hypomera with long projecting hairs near the edges.

One of the smallest species of the genus, distinguishable from duhius hy its duller and blacker integuments, much less deeply sinuate epistoma and by its relatively less transverse and abbre- viated prothorax, which, in dubiiis, is about one-third as long as the elytra. In nanus the sides of the prothorax are much less convergent anteriorly than in diibius, and the general form of the body is shorter and broader. C03i'ISATTl'S n. gen. Body oblong, subglabrous, the antennte long and slender, the anterior tibi?e produced externally at apex and the base of the prothorax transverse and straight, becoming feebly and poster- iorly oblique near the sides This genus is closely allied to Eusattus, differing in the trans- verse and not bisinuate base of the prothorax ; it is founded upon a single small species which may be described as follows : — C. rectus n. sp. — Oblong, strongly convex, rather dull, blackish-castane- ous in color, the elytral suture narrowly rufescent; legs dark rufous; anteunse and tropin paler and more flavate; integuments subglabrous, the punctures toward the sides of the upper surface bearing short inconspicuous hairs, the outer edge of the epipleurte with a long fringe visible toward base, the under surface of the the concave and longitudinally rugose propleurte without long hairs; basal margin of the pronotum completely devoid of hairs, the apical margin with an extremely short fringe.

CffiLOCIVEMIS Mann. C sulcata n. sp. — Elongate and moderately stout, strongly convex, deep black and dull throughout. Head one-half as wide as the prothorax, truncate at apex, minutely feebly and sparsely punctate throughout; antennie about as long as the prothorax, dull, minutely punctulate, each puncture bearing a min- ute decumbent hair, third joint one-half longer than the fourth and scarcely more than twice as long as wide, eleventh joint wider than long, very obliquely pointed, the sensitive pores distinct and close-set. Prothorax not quite as long as wide, widest at the middle where the sides are broadly angulate, thence broadly arcuate and feebly convergent to the apex and slightly more conver- gent and broadly, evenly and very feebly sinuate throughout to the base, the the latter truncate and slightly narrower than the apex, which is also truncate with the angles broadly rounded; basal angles slightly acute and prominent, not rounded; disk extremely minutely but deeply punctate, the punctures rather sparse, distinct under sufficient power and each lying within a large feeble dent of the surface, the latter producing a very obsoletely rugose ap- pearance. Elytra oval, not quite twice as long as wide, two and one-half times as long as the prothorax and about one-fourth wider, arcuate at the sides, the apex feebly produced and conjointly, evenly parabolic; disk finely but deeply sulcate, the sulci minutely, not closely punctate, the intervals con- vex, nearly smooth and extremely finely, sparsely punctulate. Leg>< long and sparsely punctate; tibia? densely and compactly fulvo-pubescent within toward apex as usual, the tarsi similarly clothed beneath. Length 26.0-28.0 mm.; width 9.0-10.0 mm . Utah (southwestern). Mr. C. J. Weidt. This distinct species differs from punctata in its much larger size, sulcate elytra and finer sculpture. According to Mr. Weidt it occupies a very different station from punctata, one being found only in the low sun-scorched plains, and the other in the high, moist wooded regions. BlAI'STINI. There are several elements useful in the classification of the genera of Blapstini, which, although apparently trivial in them- selves, are undoubtedly sound with tlie limits of this particular group of genera. The two to which attention should be parti- 616 Colropterological Notices, VI. ciilarly drawn are : the form of the basal margin of the prothorax^ and the presence or absence of a fringe of seta3 along the lateral edges of the body. A mere casual inspection of the numerous species of Blapstmus, and of the otherwise evidently' distinct though fewer representatives of Mecysmus, will show that the bisinuate form of base is perfectly constant throughout the former, and that the transversel}' rectilinear form is equally per- sistent in the latter; consequently it must be evident that the form of the base is of great importance, and the separation of Cybotus and Aconobius on this feature alone would be more than amply justified, irrespective of the profound ditierences in habi- tus distinguishing both of these genera. Cybotus is however further characterized by an abnormality of palpal structure, and Aconobius by the presence of a dense fringe along the sides of the body, which, in conjunction with its peculiar antennse, gives it a very striking facies. The marginal fringe is chiefly important in discriminating cer- tain wingless genera, which constitute the division with connate elytra and abbreviated scutellum. Its importance is demonstrated by its absolute constancy throughout those polytypic genera which happen to possess it, such as Ulus and Notibius, and there can be no doubt that it is an important generic character, prob- ably- developed by reason of changes in the life-habits of the species. The characters here used to separate Nocibiotes, Toni- bius and Tonibiastes are based upon types of elytral sculpture^ bodily facies and antennal structure, which are invariable through- out the respective genera where enough species are known to test their constancy, and it is probable that these genera Avill ulti- mately hold good. Conibius, as here defined, is still somewhat heterogeneous, containing three subgeneric types as noted below. The genera of Blapstini ma^^ be separated as follows : — Scutellum triangular, separating the elytra at base, the liiiul wings frequently well developed and the anterior tarsi of the male dilated as a rule. Base of the prothorax hisinuate. Anterior tibiaj bent; vestiture dual in structure Tricliotoii Anterior tibiic straight; pubescence simple. Body generally oval, fimbriate at the sides; anterior tibiae produced externally at apex I'liiS Body usually oblong or oblong-oval, the sides not fimbriate; anterior tibiie simple Blapstinus Rise of the prothorax not bisinuate. Coleopterological Notices, VI. 61 T The base straight and as -svide as that of the elytra; hody broadly oval and strongly convex Cy botllS The base straight and narrower than that of the elytra; body elongate and snbdepressed Mecy SillUS The base evenly arcuate; body narrow and convex, densely fimbriate at the sides Acoiiobius Scntellum very short and broad, not entering the disk of the elytra; body always completely apterous, the anterior tarsi never dilated in the male. Prothorax not at all fimbriate at the sides. Elytra not sulcate, the antennre stout, generally feebly and very gradu- ally incrassate toward tip and without an abruijt club C'oiiibillS. Elytra sulcate. Antennae with an abrupt three-jointed club; elytral intervals convex and asperate :Xocil>iotes Antennae with a feeldy differentiated club; elytral intervals convex and simply punctate; prothorax not narrowed behind Toiiibius Antennae not described; elytral intervals acutely costiform; prothorax narrowed behind Tonitoiastes Prothorax densely fimbriate along the lateral edges. Anterior tibiai narrow and non-fossorial ; body narrow and parallel. Conibiosoina Anterior tibiaj broadly triangular and compressed; body stout and oblong- oval XotilJius In this table the first five geneva and Conibiosoma remain with the scope originally given them (Col. Not. II, p. 409). Aconobius is fonnded upon Conibiosoma laciniata (Col. Not. Ill, p. 64), and Tonibiastes has for its type Notibius costipennis Horn, re- cently described from Lower California (Col. Baja Cal., p. 430). The other genera are separately alluded to below. The scheme of classification originally followed and more re- cently maintained by Dr. Horn for this tribe, can scarcely be regarded as coming within the domain of scientific taxonomy and will ultimately have to be discarded. CO^IBIUS Lee. The species of this genus can be assigned to three subgenera, which are widely distinct among themselves in point of general appearance, as follows : — Head parallel at the sides near the base; basal angles of the prothorax not rounded and nearly right. Body parallel, the elytra subeijual in width to the prothorax I Body oval the elytra inflated and much wider II Head prominent at the sides before the eyes; body stout, parallel and oblong; basal angles of the prothorax obtuse and bluntly rounded Ill '618 Coleopterological Notices, VI.

The species of this genus have a characteristic facies, which will render their identification tolerably certain. The six representa- tives known to me may be recognized b^' the following table : — Basal angles of the prothorax rather l)roadly oblique at the base, large and posteriorly prominent ; pronotum more obscurely sculptured, the sides less rounded. Third antennal joint fully twice as long as wide. Elytral sulci deep; legs rather slender. I'ronotum somewhat coarsely and very closely punctured. gi'aii Hiatus Lee. Coleopterological Notices, VI.

In the first group the form of the bod^- is nearly parallel, with the elytra subequal in width to the prothorax, while in the second section the el^'tra are distinctl}' wider and are suboval in form. As far as known, this genus is confined to the arid regions of southern California and Arizona.

It is described from the fe- male, and has been compared with the corresponding sex of gran- nlatus. 'X, acutiis. — Moderately stout and convex, somewhat dull, black; head and edges of the pronotum rufescent; antennae and legs brownish-rufous; in- teguments subglabrous. Head three-fourths as Avide as the prothorax, nearly one-half wider than long, the sides parallel, rather abruptly and strongly con- vergent before the middle, the apical margin moderately sinuate in the middle; surface somewhat coarsely, densely scabro-punctate, more sparsely granose toward apex; antennaj a little shorter than the head and prothorax, the third joint distinctly less than twice as long as wide and shorter than the next two combined, fourth distinctly elongate, live to eight slightly decreasing in length, the former quadrate, the latter wider than long, club abrupt, the eleventh joint much narrower than the tenth. Prothorax two-fifths wider than long, widest before the middle, the sides very feebly arcuate, becoming straight pos- teriorly, the apex extremely feebly sinuate in circular arc, almost truncate, the angles broadly obtuse and rounded; base equal to the apex, transverse and feebly arcuate, becoming perceptibly sinuate near the angles, which are acute and prominent but scarcely projecting posteriorly beyond the median parts; disk rather coarsely, somewhat deeply and conspicuously punctate, the punc- tures oval, well separated and distinctly defined, each bearing a very short decumbent hair; interspaces rather smooth and alutaceous, obscurely granu- lato-reticulate. Elytra about one-half longer than wide, twice as long as the prothorax and scarcely wider, the sides parallel and feebly arcuate ; apex con- jointly acutely ogival ; sulci deep and rather closely punctate, the intervals dull, densely granulato-reticulate and sparsely asperate. Abdomen sparsely punctate, the propleurai moderately coarsely and densely scabrous. Length 4.0 mm. ; width 1.45 mm. Arizona. The type is a male, having the anterior tibisB rather stout, bent inward at apex and feebly prominent on the inner margin just behind the middle, the abdomen feebl}- impressed, more coarsely and closely punctate and more noticeabl}- pubescent in the middle toward base, and the fifth segment broadly, feebly impressed. This species differs from granulatus principall}'^ in its shorter form, much shorter and stouter anterior tibia" in the male, coarser, sparser and more distinct pronotal punctures, and in its decidedly shorter third and narrower eleventh antennal ioints. J Coleopterological Notices, VI. 621 W. caudatllS. — Elongate-snboval, strongly convex, somewhat shining but alutaceous, bhick; legs dark rufous, the antennas rufo-piceous; integuments subglabrous, the pronotal punctures bearing minute decumbent hairs and the elytral asperities bearing much inclined coai'se seta?, which are quite distinct toward tlie sides. Head scarcely two-thirds as wide as the prothorax, slightly transverse, with rather small, deep, distinct and separated punctures, the apical emargination broad and subangulate; antennae long, fully as long as the head and prothorax, the third joint much more than twice as long as wide and rather longer than the next two, club only slightly abrupt, the penultimate joints nearly as long as wide, the eleventh not narrower. Prothorax feebly transverse, barely two-lifths wider than long, widest somewhat before the middle but with the sides evenly and feebly arcuate throughout, not becoming straight posteriorly, just visibly sinuate for a very short distance before the basal angles which are right, not rounded and scarcely at all posteriorly prom- inent, the base transverse, becoming very feebly sinuate near the basal angles^ apex quite distinctly narrower than the base, very evenly emarginate in cir- cular arc, the angles distinct and only slightly blunt ; disk evenly smooth and convex, finely, deeply evenly and somewhat sparsely punctate, the punctures becoming gradually a little coarser, denser and less defined toward the sides; interspaces shining. Elylra fully three-fifths longer than wide, more than twice as long as the prothorax, and, in the middle, one-fourth wider; sides evenly arcuate; humeri broadly rounded, not exposed; apex acutely and grad- ually ogival, each elytron produced in a short punctate and pubescent caudal appendage; sulci deep, punctate, the intervals each with a single even series of coarse asperities.

Abdomen strongly but not very closely punctate. Length 4.5 mm. ; width 1.7 mm. Arizona. Mr. Wickham. The type of this species is also a female, and is very closely 622 Coleopferoloc/ical Notices, VI. allied to caudatus, (littering in the shorter, non-caudate elytra, denser punctures of the head and pronotum, coarser abdominal punctuation, shorter antennae and smaller size. The type is from a locality in Arizona, widely different from that of caudatus, and there is reason to believe that the caudal process in the latter is as permanent and invariable a feature as in Eleodes caudifera Lee; so there appears to be but little doubt of the validity of the species. TOXIBIIS n. gen. The only species which can 1)e referred to this genus for the present are sulcatus Lee, and alternatus Cs,\. The latter of these species is in no sense an abnormal state of the former, of which I have before me an ample series, no specimen of which displays any tendency to vary in the direction of the peculiar specific characters of alternatus. In alternatus the size is materially greater than is CA'er attained by s»/cfl/».s,and the sculpture of the pronotum is very much coarser. NOTIBirS Lee. This is a natural and distinctly characterized group of species, in which the body is stout, oblong and convex, with a dense de- cumbent fringe along the lateral margins of the prothorax, and broad fossorial anterior tibial in both sexes. The four species may be distinguished at once b^' the following strongly marked and constant characters : — Third antenna] joint elongate, gradnally and feel)]y obconical from base to apex. Sides of the pronotum broadly reflexo-explanate pilbei'lllus Lee. Sides not at all or very narrowly subexplanate. Head parallel at base; apical angles of the prothorax obtnse but evident externally ; pronotum coarsely and deeply' punctate. siibfiiti'iatiis Csy. Head subangularly prominent at base; apical angles of the prothorax very l)ioadly and transversely rounded ; pronotum very tinely, feebly and sparsely punctate laticeps Csy. Third anteinial joint short, only slightly longer than wide and dilated at apex. piiiicticollis Lee. Of sul)striatus I have a large series, taken by Mr. Weidt in southwestern Utah ; it extends thence to the elevated plains of the Mojave Desert in California. Paherulus is represented in Coleopterological Notices^ VI. 623 my cabinet by two perfectly similar specimens from the less ele- vated desert regions of the extreme southern part of California, whence it was originally described, and laticeps by four homo- geneous examples. Puncticollis is more northern in its range in California. BOLITOPHAGINI. The North American genera of this tribe seem to be more con- veniently divisible into primary groups upon the basis of anten- nal structure than by the structure of the eyes, and, the occur- rence of an interesting new type in the Pacific coast region, af- fords an opportunity to outline their distinguishing characters as follows : — Anteniife lO-jointed, the third much elongated, tenth perfectly free, the ninth not emarginate; eyes not divided; prothorax broadly pednncnlate at base. Bolitotliei-us Antennae 11-jointed. Eleventh joint free, the tenth broadly arcuato-truncate at apex; eyes com- pletely divided. Pronotum tuberculose; elyti'a with coarse interrupted ridges. Bolitopliagiis Pronotum punctate; elytra Avith fine continuous ridges Eleates Eleventh joint set partially within the emarginate apex of the tenth and in close contact throughout the width ; eyes not divided. Mentum not carinate; elytra with series of tubercles Iflegeleates Mentum with a strong compressed keel; elytra with tine even ridges. Eledoua Eledona appears to be of doubtful occurrence in the United States, but is introduced for comparison. MEGEI.EATES n. gen. Body thick, subcylindric. Head deeply inserted, the apical margin not reflexed except feebly toward the sides, continuously and evenly arcuate, obtusely prominent laterally before the eyes, the latter moderately coarsely faceted and one-half divided. Max- illar}' palpi subcylindric in form, the joints in close mutual con- tact, polished and sparsely punctulate, the last cylindro-conical and nearly twice as long as the third. Antennal grooves beneath the eyes moderately deep. Antennte with the third joint only slightly' elongate. Prothorax not in the least pedunculate at base. Scutellum oval, truncate at base. Epipleurre horizontal, rather 624 Goleopterological Notices, VI. wide and of almost equal width from the base to within a short distance of the apical angles, where they become rapidly nar- rowed. Anterior coxje moderately separated, the intermediate more widely, the process of the mesosternum slightly tumid and anteriorly excavated to receive the prosternal process ; posterior separated by two-thirds of the coxal width, the abdominal process broadly rounded. Met-episterna narrow and parallel. Legs short and stout; tibite tricarinate externally; tarsi thick, the last joint of the posterior as long as the preceding three. ]fl. sequoiariiiii n. sp. — Oblong, stronglj^ convex, opaque throughout, black and glabrous. Head not coarsely but strongly scabro-punctate, Avith a tuberculiforni elevation above each eye; antennie as long as the width of the head, the three outer joints broader and minutely, denselj' pubescent, joints before the club triangular, ninth and tenth strongly transverse. Profhorax fully twice as wide as long, twice as wide as the head, the apex three-fourths as wide as the base; sides evenly arcuate throughout and strongly crenulate; apical angles advanced; base arcuate, becoming obliquely sinuate toward the sides; disk rather abrujitly and broadly reflexed toward the sides, covered with coarse separated tubercles, sulcate along the middle, the sides of the sul- cus becoming carinate anteriorly in the male but simply tumid in the female. Elytra parallel, subetjual in width to the prothorax, about two-fifths longer than wide, broadlj- but evenly rounded at ape.x; side margins slightly promi- nent, more so and cariniform toward apex, stronglj- crenulate, not at all re- flexed; disk vertical at the sides, having regular series of rather coarse, close- set, opacjue tubercles, the intervals each with a series of coarse and rounded punctures separated by small tubercles; third, fifth and seventh series of tubercles more i^rominent, the third especially so toward the summit of the apical declivity, which is almost vertical in profile. Abdomen strongly and closelj' punctate, the legs less coarsely, strongly and very densely punctate. Length 6.5-7.0 mm. ; width 3.4-3.() mm. California (Big Trees, Calaveras Co.). Dr. Blaisdell. The sexual differences are very feeble, the male having the sides of the pronotal sulcus more prominent and laminate toward apex, as stated, and the general form of the body sensibly shorter. Sev- eral specimens. ANTHICID.E. The following studies were undertaken largely for the purpose of identifying and naming a considerable number of nondescripts, which have been accumulating for many years, but, at the same time I have become much interested in the general grouping and classification of the genera, points which were left in a very un- Coleopterological Notices, VI. 625 satisfactory state by LeConte and Horn, the very important and obvious abdominal structure of the Xylophilin;i?, for example, being completel}' overlooked by these usually acute observers. The last revision of the American species, as a whole, was pub- lished by LeConte more than forty A'ears ago, and is at present of course very incomplete. The sexual characters of the abdomen are in some groups verv pronounced and in others feeble, differing greatly in general character in the various genera and usually varying distinctly in degree from species to species. In the Eur^-geniini the external modifications are conspicuous only in Retocomus, and in that tribe the intromittent organ is of a somewhat simple type throughout. In Pedilus (=Corpliyra) and Macratria, genera with distinct tarsal modifications, the external characters are feeble, while the intromittent apparatus becomes marvelously complex. These facts tend to prove still further that primary sexual char- acters, when differing distincth' in type, may in certain cases be quite as valuable in defining genera as any other structural modi- fication. The well known scarcity of individuals in many parts of the series, as for instance in the Eurygeniini and Xylophiliufe, results in all probability, chiefly from the fact that we do not know the habits of these insects, which are very diflferent from the epigeal Anthicini. It is possible that each species ma}^ appear in abun- dance only at certain very limited seasons or on certain individ- ual trees, as is known to be the case with a number of longicorn groups of suppossed excessive rarity. The Anthicidse may be divided into two important subfamilies as follows: — Abdomen composed of five free segments; tarsus with the penultimate joint lobed beneath; tibial spurs generally distinct; labial palpi minute. Anthicini Abdomen composed of four free segments, the first formed of two amalgamated somites with the suture sometimes indicated; tarsus witli the antepenulti- mate joint lobed beneath, the penuHimate small; tilnal spurs generally obsolete; labial palpi witli the last joint large and more or less dilated. XVLOPHILINiE Anthicini. This subfamily may be divided into five tribes by the following -characters : — G26 Goleo2oterological Notices, VI. Tarsal claws appendiculate ; eyes emarginate and finely faceted; neck wide; maxillary palpi slender Nkm atoplini Tarsiil claws not appendiculate. Neck wide; eyes large, finely faceted and generally emarginate; basal seg- ment of the abdomen not elongate. Prothorax constricted at apex and margined at base; tarsal claws simple or with a feeble dentiform dilatation at base EURYGENIIXI Prothorax not constricted at apex, margined at base; tarsal claws with a pointed lamelliform tooth internally at base, the apical part abruptly bent Pedilini Neck narrow; eyes not emarginate; prothorax constricted at apex. Eyes large, oval, rather finely faceted; basal segment of the abdomen elongate ; claws somewhat as in Pedilini M ACRATKIIXI Eyes small, rounded, not emarginate, generally coarsely faceted; basal segment of the abdomen not conspicuously elongate; claws simple. Anthicixi The first four of these tribes are arboreal in habit, the fifth epi- geal. The Xj'lophilinse are arboreal, and it might therefore be considered best to put them at the head of the familj^ instead of immediately succeeding the Anthicini ; but it will be observed that the Xylophilinse differ quite as much, if not more, from the Eurygeniini as from the Anthicini, and it is therefore immaterial where we place them. Again, the apical constriction of the pro- thorax, which is such a constant and peculiar feature of the An- thicini, is even more strongly developed in the Eurygeniini, and is altogether obsolete in Xylophilin;^ ; the eyes are finely faceted in all the larger forms constituting the first tribes, coarsely so in Anthicini and generally very coarsely so in Xylophilinse ; so, con- sidering the question from all points of view and having due re- gard to the small size and less highly developed structure, as shown by the amalgamated basal segments of the abdomen, it seems more fitting to place the subfamily at the end of the series. Concerning the erection of a distinct family for the Xylophi- linae, as proposed by Mr. Champion, I regret to have to disagree. The sclerites of the under surface, especially near and between the middle coxa^, are identical in Anthicus and Xylophilus, ex- cept that the mesosternal [process in the latter is not quite so long, and there is, besides, a certain indefinable habitus possessed by the two t^^Des in common, which seems to show that they should not be Avidely separated. Coleopterological Notices, VI. 627 Nematoplini. The exceedingly rare Neinafoplus coUaris Lee, is at present the onl_y species assignable to this tribe. The hind tarsi are fili- form throughout, with the third joint simple and cylindrical ; this very exceptional structure in the first genus of the subfamily be- ing similar to that of Mecynotarsus, which I have placed at the end. The tarsal claws are by no means cleft, as stated b}' Le- Conte and Horn (Class. Col. N. A., p. 410), but are simple and thickened or subdentate internally at base, where there is attached a long slender minutel}" pubescent appendage, which almost equals the claw in length; besides this remarkable appendage, there is a distinct bisetose onychium between the claws.* The last antennal joint is not unusually elongate, and the feeble apical constriction of the prothorax does not extend laterally upon the flanks. EURYGENIINI. The genera composing this tribe are somewhat numerous, and are confined entirely to the new world ; those known to me at present may be distinguished as follows : — Last joint of the antennae not noticeably elongate. Eyes narrowly and distinctly emarginate. Tenipora prominent; antennte filiform; maxillary palpi large, with the last joint triangular Retocomiis Tempora not prominent; antennas serrate and very long; maxillary palpi small, filiform, the last joint cylindrical and not much longer than the preceding Hastorenius Eyes truncate or broadly and feebly sinuate; antenna; filiform. Tempora well developed and prominent. Eyes large; spurs of the hind tibiae short; last joint of the maxillary palpi long and cultriform Stereopalpu!^ Eyes much smaller; spurs of the hind tibiie long; maxillary imlpi greatly developed, very broad, the joints triangular Pergetus Tempora not prominent; eyes very large; tibial spurs short. £iirygeiiiiis Last joint of the antennie much elongated Bactrocei'US These genera are all North American, except Eurygenius, which is confined as far as known to Brazil. The third joint of the hind tarsi is triangular, not dilated and not membranous or *The claws were described properly by LeConte in tlie original diagnosis of Nematoplus (Proc. Ac. Nat. Sci., Phila., 1855, p. 275). Annals N. Y. Acad. Scr., VIII, Sept., 1895.— 43 628 Goleopterological Notices, VI. noticeably produced beneath. Bactrocerus contains a single species from Lower California, which I do not have before me at present; the pronotum is covered with coarse sparse and crescen- tiform granulations, and has the vestiture coarse and sparse. RETOCOmUS n. gen. The North American species hitherto regarded as Eur3^genius, differ so greatly from the South American type as defined by La- Ferte, that it seems impossible to avoid defining a distinct genus to receive them, and for this the above name is suggested. In the type of Eur3genius the eyes are not emarginate and the tempora are not at all prominent, besides many other diflferences, notably in the organs of the mouth. LeConte and Horn state that in Eurygenius muriniis — which is the only species which I have not been able to examine, — the eyes are practically not emarginate; this species seems also, from the original description of LeConte, to depart markedly in vestiture from the others^ and future study may possibly prove it to be genericall}'^ distinct; it occurs in Georgia and Alabama. In all the other representa- tives the emargination of the e^'es is deep and distinct, not essen- tially differing in consftnetus. Our species may be defined as follows : — Elytra each with five narrow vittie of fulvous puhescence wildi Lee. Elytra with uniformly colored pubescence, Avhich is uneven in distribution. Species of the Atlantic region niiiriniis Hald. Species of the Pacific coast. Prothorax with a strongly developed arcuate apical lol)e and a deep broad constriction; elytra vaguely subvittate coiistrictlis Lee.

Abdomen clothed with much shorter, more recumbent pubescence; elytra distinctly more than twice as long as wide. decorelliis n. sp. The two sexes of ivildi seem to differ a good deal in general form, the male being smaller, more slender aiid with subcunei- form elytra ; in the female the elytra are broad and parallel. All the species which I have examined have the basal joint of the bind tarsi strongly contorted at base, a character which is J Coleopterological Notices, VI. 629 purel}' asexual, and scarce!}' at all developed in the genera of this tribe which have iinemarginate eyes. In Mastoremus, which also has emarginate eyes, it is very noticeable, and there raaj- possibly be some correlation between these characters. R. s;ratllS. — Eather narrow, black, the femora and tibiae toward base slijihtly rufescent, sparsely clothed with complex pubescence, consisting of al- most evenly distributed suberect short gray hairs, widely scattered long erect l)laek setoe, and decumbent coarse white hairs in uneven widely scattered spots on the elytra. Head as wide as the prothorax, about as long as wide, the eyes large and prominent, separated by but slightly more than their own width on the front, the latter coarsely, densely punctate and coarsely shaggy; antennae slender, moderate in length; palpi moderate. Prothorax as long as wide, rounded on the sides at apical third, thence feebly convergent and broadly, evenly sinuate to the base; apical constriction fine, extending across the dorsal surface; apical lobe short, three-fifths as wide as the base; disk not canalicu- late, not very coarsely, densely punctate and dull, the punctures longitudin- ally coalescent. Scutellum clothed with white hair. Elytra scarcely more than tmce as long as wide, fully three-fourths wider than the the prothorax and rather more than three times as long ; sides subparallel and nearly straight to apical fifth, then almost evenly rounded, finely dehiscent toward apex, the sutural angles right; disk polished, coarsely, deeply punctate, the punctures separated by about their own diameters. Under surface shining, moderately closely punctate and clothed with long hair, quite sparsely on the abdomen. Legs moderate, the femora gradually stout; tibia; roughly asperate externally; hind tarsi fully three-fourths as long as the tibiae, with the basal joint strongly contorted at base and much longer than the fourth. Length 8.4 mm. ; width 2.2 mm. California (Sta. Cruz Co.) The two specimens are perfectly similar males, having the fifth ventral deeply excavated in the middle throughout the length, the sides of the excavation prominent and lamellate posteriori}'. R. decorellllS. — Moderately slender and convex, black, the tibiae, ex- cept at base and apex, and the basal parts of the femora feebly suffused with rufous; elytra with a feeble violaceo-aeneous metallic lustre; vestiture nearly as in (jratun but still somewhat sparser, the elytral spots rather more numer- ous and more evenly scattered. Head densely punctate and dull, the eyes large and prominent, separated on the front by quite distinctly more than their own width; antennae slender, filiform, the basal joint stoutest, but little longer than the head and prothorax. Prothorax noticeably longer than wide, rounded on the sides anteriorly, subparallel and broadly, feebly sinuate thence to the base, the apical node short, nearly two-thirds as wide as the base; disk (lull, moderately coarsely, deeply, longitudinally punctato-rugose, the sculp- ture but little concealed by the vestiture. Scutellum clothed as usual with white pubescence. Elytra almost twice as wide as the prothorax and much 630 Goleopterological Notices^ VI. more than tlu-ee times as lonji, about two and one-half times as long as wide, polished, coarsely, deeply punctate nearly as \u grains. Under surface sparsely hairy, the legs moderately stout, the basal joint of the hind tarsi l)ut slightly longer than the last. Length 8.8 mm. ; width 2.4 mm. California (Marin Co.). The single male before me represents a species allied rather closely to gratus, but differing in a number of well marked struc- tural characters. The elytra are more elongate and more finely pubescent than in gratus, and, although the large deep excava- tion of the fifth segment is nearly similar, the copulatory spicule differs decidedly, being much stouter, with a broad dorsal im- pression extending only slightly be^'ond the middle of its length ; in gratus it is more attenuate, with the dorsal channel fine, ex- tending almost to the extreme tip and gradualh* disappearing.

It is possible that Eurijgenius muri- nus may be better placed in the present genus, but a renewed inspection of the palpi would be necessary- to decide.

I find, liowever, that the spotted vestiture is a constant asexual character in other species, or at least is not at all characteristic of the female, and, besides this, these two specimens differ structurall}- to a considerable degree, the entire form of the body being different; finally, the deep me- dian sulcus o{ impressicoUia exists only as a vestige in indutus.

The species composing this genus have heretofore been re- garded as a simple section of Anthicus, but the structure of the mesosternum and prothorax, as well as their peculiar general habi- tus, demands a separation of them from that unwieldy complex. They are ver}^ numerous in the United States, especially in the arid southwestern country, as shown by the results of recent skillful collecting in those regions. This genus differs from the others more closely allied, in the great development of the fourth joint of the maxillary palpi, and the long tactile setse, which are so conspicuous a feature in Mal- porus, are completely wanting; the punctuation is very fine and dense as a rule, also in striking contrast to that genus. In re- gard to the cedeagus, I have seen no specimen with the apparatus snfficientl}' protruded for examination, and I have not had enough time or duplicate material to make dissections, but it is doubtless somewhat complex in structure. It is scarcely possible that Lappus can be identical with the South American Ischyropalpus of LaFerte, for neither Lappus obscurus nor L. sturmi (elegans) seems to have suggested to the author an alliance with Ischyroj^a^iKS jjei'plexus (Mon., p. 142), but in case obscurus and perplexus should prove to be congeneric, there is no reason why the name Isch^-ropalpus should not be re- stricted to either sericans or trigonocephalus (1. c, pp. 143, 146), as the first is probablj^, and the second certainly', generically dif- ferent from perpilexus.

I took the single male tj'pe at El Paso some j^ears ago, and the Arizona specimens, collected b}' Mr. Wickham, do not seem to differ, the male from Peach Springs being simply' a little more sparsely punctate ; two specimens, marked " Kansas," are also attached, as the differences presented are purel}- varietal. The male has the fifth ventral broadly rounded behind, becoming feebly subtruncate in the middle and unmodified on the disk, the genital segment broadly, feebl}' sinuato-truncate throughout tiie width. The last joint of the maxillary palpi is very large and wide, with the outer side but little longer than the inner. 5. Li. alacei* n. sp. — Narrow, polished, pale rufo testaceous, the abdomen, elytra in posterior two-thirds and antenna; except toward base, blackish.

Abdomen polished, minutely, remotely punctate, sparsely, somewhat ■coarsely pubescent. Legi^ moderate in length, the femora rather stout. Length 2.7 mm. ; width 0.75 mm. Utah (southwestern). The sparse punctuation, narrower form and still longer, more slender antennse, will prove sufficient to distinguish this fine spe- cies from the preceding, which it resembles in general facies. The single male in m}^ cabinet has the fifth ventral rather broadly truncate at apex, but unmodified on the disk, the genital segment broadly, feebly sinuato-truncate throughout its width. 6. I,, nubilatiifti n. sp. — -Narrow, polished, pale ruf o-testaceous, the abdo- men, posterior parts of the elytra and antenme except toward base, piceous-black.

AMomcn polished, feebly pubescent. Legs long and slender. Length :2.(>5 mm.; width 0.7 mm. Arizona. This species, and the two preceding, are unusuall}- closely allied ximong themselves, but nubilalus may be distinguished from both 662 GoleojJterological Notices, VI. by the greater extension of the head behind the eyes and parallel elytra, which are abruptly and broadly rounded at apex and not gradually narrowed behind the middle. From cursor, in addi- tion, it may be known b}' its smaller size, much narrower form, narrower and less transverse anterior lobe of the prothorax and much sparser punctuation throughout, and, from alacer, by its narrower prothorax, with the punctures denser along the middle anteriorlj', narrow and strong post-scutellar impression and several other characters. The sexual characters of the single male before me are nearly similar to those of alacer. 7. Li. liTidllS n. sp. — Narrow, the elytra rather depressed, polished, pale rufo-testaceous, the abdomen except at base, the elytra behind the middle and the last five joints of the anteunsc blackish; elytra frequently entirely pale.

Aljilomcn shining, the legs rather long and slender. Length *2.7-2.9 mm. ; width 0.7-0.*^ mm. Texas (San Antonio). The male has the fifth segment unmodified, feebly truncate at apex, the genital segment broadly and deeply .sinuato-truncate throughout its width, the lateral angles rather prominent. This well marked species is represented by three specimens. 8. L,. Sturmi Laf. — Mon., p. 304; clcgans \\ Laf. : 1. c, p. 117; Lee: Proc. Ac. Nat. Sci., Phila., 1852, p. 96 (Anthicus). This ver}^ distinct species is amply described by LaFerte under the preoccupied name elegans. My two specimens were taken at Asheville, North Carolina. Length 2.7 mm.; width 0.75 mm. Coleopterological Notices, VI. 663 The male has a strong internal and subprominent dilatation of the posterior tibiae just beyond the middle, the fifth ventral feebly siibtruncate, with the surface slightly more finely reticulate and clothed with longer stiffer hairs toward the middle, and the geni- tal segment, as usual, broadly sinuato-truncate. Sturmi is prob- ably a somewhat local species and does not appear to be abundant. 9. Li. iiitidillus Lee. — Ann. Lye. Nat. Hist., N. Y., V., p. 153; Proc. Ae. Nat.

Length 2.75 mm.; width 0.85 mm. California. The male has feebly marked sexual characters, as in cursor and alacer. This description refers to the typical nitidulus, but among my large series from various parts of the State, it is eas}' to distinguish a number of more or less well marked varieties, some of them so marked that there can be but little doubt that there are several closel3' allied species included ; they all agree, however, in having the head comparatively small and strongly, asperately punctate, and the anterior lobe of the prothorax widest near its base. Most of them have the basal parts of the elytra paler, the completelA' black forms, which may be regarded as typical, being rather rare. One specimen is from southwestern Utah. 664 Coleopterological Notices, VI. 10. L.. asperulllS n. sp. — Moderately stout and shining, dark rufo-tes- taccous, the elytra posteriorly, abdomen and antenna?, except near the base, blackish; legs pale. Hcful small, moderately convex, very strongly, closely and asperately punctate, broadly rounded behind, the temporal angles quite distinct; eyes rather large; antenuiTe less than one-half as long as the body, rather stout, incrassiite, the tenth joint barely longer than wide. Prothorax only slightly narrower than the head, a little longer tlian wide, the anterior lobe transverse, strongly rounded and widest at about its basjil thii'd ; basal lobe wide and large, with its sides straight and evenly, moderately divergent from the sharply angulate constriction to the basal margin, which is distinct and flat; surface convex, finely, rather sparsely punctate; pubescence not con- spicuous. Elytra broad and rather short, scarcely more than two-tliirds longer than wide, fully twice as wide as the head, slightly wider behind the middle than at base, broadly rounded behind; humeri very widely exposed; scutellar impression feeble, the omoplates moderately prominent; transverse impression distinct; punctures moderately close, conspicuous and asperulate throughout the disk. Abdomen polished, sparsely pubescent, the legs moderate in length,^ with the femora rather stout. Length 2.6 mm. ; width 0.85 mm. Oregon (Portland). The type of this species is unfortunateh' a female, but its el^'tra are mucli shorter tlian in any of the forms of nitidulus which I have seen, and the antennal joints are also much shorter. As it is unique, it is impossible to pronounce any definite opinion con- cerning the normality of the el^'tral asperities, and the}' may possi- bly be due to accident in this individual. I have, however, a good series collected in the Hoopa Val., Humboldt Co., Cal., which agree fairl}^ well in form, color and structure with the Oregon type, but which have the elytra smooth; they may be regarded a& conspecific until more individuals of the form selected for descrip- tion can b(! obtained. 11. Lr. canon icilS n. sp. — Narrow, polished, rufo-piceous, the abdomen and elytra black, the latter pale testaceous in basal third or fourth; legs and antennai pale testaceous, the latter blackish toward apex.

Abdomen pol- islied, sparsely pubescent, the legs long and slender. Length, 2.4-2.9 mm.; width 0.7-0.85 mm. California (southern). Mr. H. C. Fall. In the male the fifth ventral is unmodified, very broadly rounded behind, the genital segment as usual broadly, feebly sinuato-trun- cate. This species is allied to the two preceding, but differs from both in its much narrower form of body and more elongate and slender antennje; from nitiduhis it diff"ers also in color, relatively much smaller and narrower prothorax, larger head and stronger subbasal impression of the elytra, and, from asjierulus, in its very much sparser elytral punctures, among other features. Three specimens. 12. L.. oriiatelllis n. sp. — Narrow, polished, black or blackish, the legs concolorous; antennie testaceous toward base; elytra with the basal margin pale; pubescence fine and very sparse, dark in color and entirely inconspicuous, ex- cept in basal third of the elytra, where it becomes cinereous and coarser but not denser.

Elytra not quite twice as long- as wide, two-thirds wider than the prothorax, slightly dilated behind the middle, the sides thence distinctly convergent to the narrowly subtruncate apex; scutellar impression broad, the omoplates large and distinct, the trans- verse impression subobsolete; punctures minute and sparse throughout, only slightly more distinct toward base. Abclomm polished, sparsely pubescent, the legs slender. Length 2.4 mm. ; width 0.7 mm. Arizona (near the Grand Canon). Dr. Prudden. The male has the fifth ventral broadly and just visibly sinuate at apex, the genital segment feebly sinuato-truncate. Three speci- mens. This is the only bicolored species which has the pale area of the elytra confined to the base, and not extending behind the omoplates. 666 Coleopterological Notices. VI. 13. Li. vivicllis n. sp. — Narrow, polished, pale flavo-testaceous, the ab- domen fuscous; elytra in posterior two-thirds piceous or blackish; antenna; black except toward base.

Ab- domen polished, sparsely .pubescent, the legs slender. Length '2.2 mm.; width 0.65 mm. Arizona (Tu9son and Pinal Mts.). The four specimens before me are females and represent a well defined, small and very delicate species, not closely allied to any other here described. 14. I^.bipartitll!>in. sp. — Subparallel, the elytra rather depressed, polished throughout, pale llavo-testaceous, the abdomen except at base and elytra, ab- ruptly in posterior three-fifths, blackish; antenna; gradually fuscous toward apex. Head but very slightly wider than long, convex, minutely and re- motely punctate, transversely rounded at base, the temporal angles well- marked though obtusely rounded; eyes rather large and prominent; antenna? moderately slender, fully one-half as long as the body, the outer joints just visibly thicker, the tenth distinctly elongate. Prothoia.v large and thick, con- vex, slightly narrower than the head and a little longer than wide, minutely, evenly and not very sparsely punctate; anterior lobe somewhat transverse, oval, large, Avidest neunctate, the eyes prominent ; antennae slender, scarcely as long as the head and protliorax, feeblv thickened toward apex, the pe- nultimate joint fully as long as wide, the last short, second and third equal and but slightly shorter than the first which is thicker. Prothorax not quite as wide as the head, a little longer than wide, acutely constricted somewhat behind basal third, the punctures fine and very sparse except toward base, where they become coarse and very dense, the two transverse tubercles more or less distinct, the surface before them apparently somewhat impressed. Elytra elongate, very nearlv twice as long as wide, twice as wide as the prothorax, quite distinctly wider at the middle, the punc- tures coarse and sparse ; pubescence spai'se, short, pale through- out. Length 2.5-2.8 mm.; width 0.8-0.9 mm. California seacoast from San Diego to San Francisco. The apex of the abdomen is generally pale, and, in the male, the fifth segment is distinctly longer than the fourth, rounded and not at all truncate at apex, with the surface A'ery obsoletel}' and broadly impressed along the middle, and gradually just visibly reflexed toward tip, the genital segment with a small feeble and circularly rounded apical sinuation, and a transverse discal impression, the apical edge fringed with stiff hairs. In this species the male intromittent organ is quite different from that of texanus and mimus ; it is not quite so long, and the dorsal corneous sheath has the sides nearly straight and feebly convergent from the base almost to the apex, where it be- comes abruptly narrowed and very feebly bent downward, the narrow ligula short, subparallel, obtuse but not distinctly en- larged at apex. The intromittent duct proper, lying beneath the sheath, is slender, simple, coriaceous and extends slightly beyond the apex of the sheath. 5. T. franciscaiius n. sp. — Moderately stout, convex, shining, pale rufo-testaceous, the entire under surface of the hind body, and a moderately large cloud near the middle of each elytron, black; antennae and legs pale throughout. Head rather longer than wide, convex, strongly and rather closely punctate; eyes moderately large, prominent, situated somewhat before the middle of the medial length; antennte somewhat stout, distinctly iucras- sate, scarcely as long as the liead and prothorax, the tenth joint about as long as wide. 1'rofhorn.r ample, not distinctly narrower than the head, a little longer than wide, rather feebly convex toward the middle, finely but strongly punctate, the punctures somewhat sparse anteriorly l)ut becoming dense to- ward base, the two Itasal tubercles distinct; pubescence inconspicuous; an- 674 Goleopterological Notices, VI. terior lobe larf^e, transverse, widest at its anterior third, the sides convergent and rounded to the acute constriction ; posterior lobe distinctly less than one- third the total lengtli, rapidly expanded to the basal margin.

Abdomen alutaceous, tinely pubescent. Legs moderate in length and rather stout. Length 3.1 mm. ; width 0.95 mm. California, (near San Francisco). The single male before me indicates a species which is appreci- ably larger than calif ornicus, and the sexual characters are quite dirterent. The fifth ventral is short and but slightl_y longer than the fourth, its apex broadly, just visibly sinuate, and its disk unmodified ; genital segment deeply, angularly emarginate in the middle at apex, the emargination but slightly' more than twice as wide as deep, the disk with a large deep and transversely oval impression, and the posterior edge fringed with stiff, inwardl}^ di- rected cilia. In this specimen the extreme tip only of the copu- latory sheath is exposed, but this is much broader and more ob- tuse than in californici(i<, and there is, in addition, a slender thin fillet at each side of the sheath-apex, of which I can find no homo- logue whatever in that species. VACrSlTS n. gen. The members of this genus are small, narrow and usually pol- ished, sparsely punctate and pubescent species, of peculiar facies, but not unremindful of some of the various forms of Anthicus. They also resemble Anthicus in autennal, oral and crural struc- ture, but difier completely in the entire conformation of the meso- sternum, as detailed in the table of genera. They present three tjqjes, quite distinct in appearance and environment, represented b}- lastas, 7ii(ji'ilt(lus and formicetorum, the first inhabiting the Southern States from Florida to southern California, the second peculiar to the true Pacific coast fauna, and the third to the desert regions of the Sonoran province. The latter is remarkable, in addition to its peculiarities of facies, in that its closely allied components are m^'nnecophilous in habit, the S3'mbiosis how- ever probably not being complete.

A series of seven specimens, all that 1 obtained in the Hoopa Val- ley, Humboldt Co., are pale ochreous-flavate throughout, other- wise agreeing in every particular with the ordinary black form which also seems to be very constant in coloration. In this section of the genus as represented by the present spe- cies, the genital segment of the male is less elaborately modified than in Icetus, the two lobes being flattened, gradually acuminate and bent downward, the tips abruptly and minutely inflexed ; the intromittent organ is very slender but shorter, feebl}^ swollen to- ward apex and then gradually, finely acuminate and scarcely per- ceptibly bent downward.

Narrow, feebly shining, pale brownish-testaceous throughout, the vestiture rather coarse and close, finer and short anteriorly, longer, coarser and much more conspicuous on the elytra. Head quadrate but strongly' trapezoidal before the eyes as usual, con- vex, closely and distinctly- i)unctate, the punctures intermingled with short feeble scratch-like rugulosities especially anteriorly ; eyes moderate, nearly as long as the tenipora, the latter parallel for only a very short distance, then broadly rounded to the truncate base ; antenna? short, not quite as long as the head and i)rothorax, slender and filiform except the last five joints, which are rather abruptly enlarged, the penultimate joints not quite as long as wide. Prothorax scarcely longer than wide, fully as wide as the head, prominent and angulate at the sides anteriorly, obli(iue and feebly sinuate thence to the fine basal margin, circularly rounded anteriorly; surface convex, finel}', densely punctate, the pubes- cence posteriorly inclined above but lying transversely on the flanks, more broadly behind, thus producing two feebly marked oblique lines of demarcation meeting at the middle of the base.

This very small species may be distin- guished at once from the two which precede, not only by the characters given in the table, but bj' the more abrupt and notice- ably enlarged five outer joints of the antennae. In formicetorum these joints form a true, though feeble, five-jointed club, while in desertorum the transition from the sixth to eighth joints is so gradual in width, that there is scarcely the suspicion of a club. 10. y. suspectiis n. sp. — Moderately stout and convex, feebly shining, pale brownish-testaceous, the suture and apex of the elytra clouded with blackish; pubescence close and conspicuous, much longer on the elytra. Head ((uadrate, convex, rather coarsely and somewhat closely punctate, the inter- spaces smooth and even; eyes small, much shorter than the tempora, the latter liarallel for a long distance behind them, thence rather nanowly rounded into the broadly arcuato-truncate base; antenuic missing in the type. Prothorux large, about as long as wide and very distinctly wider than the head, the out- line nearly as in the three preceding species; surface convex, finely and densely pimctate. Elytra large, two-thirds longer than wide, not quite twice as wide as the prothorax, perceptibly dilated behind the middle, broadly, obtusely rounded at apex, the humeri widely exposed at base; disk strongly and conspicuously impressed at the scutellum, closely strongly and rather coarsely punctate.

The unique t^pe is a female from the Levette cabinet, and is in nil probability from the locality stated above. It represents a much larger and stouter species than /brmiceforwm, with smaller eyes and more parallel tempora, besides the other characters here- tofore mentioned. HEMAiXTUS n. gen. The general habitus of Anthicus Jloralis is peculiar and aber- rant in its smooth subglabrous surface, in the occurrence of a .subapical modification of the pronotum — always a significant structure in this family, — in its stout antennae, robust legs with (luite distinctly clavate femora, and other features, so that its systematic position among the other species has always been uncertain. When we add to these disparities of structure the Coleopferological Notices, VI. 683 singular modification of the mesosternum, tliere can be but little doubt that the correct solution of its taxonomy is the erection for it of a distinct genus, and at the same time, the radical varia- tions in this mesosternal structure show beyond peradventure that several distinct species have been confounded, not only in this country but in Europe. The material in my cabinet can be resolved into the four fol- lowing well characterized specific forms : — Mesosternum greatly dilated at tlie sides, extending with rounded outline more than half way between the coxse and the elytral humeri, its outer margin beiiring a close fringe of long fine decumbent hairs ; pronotum con- stantly Avith a small feeble double tubercle in the middle near the apex. (Subgenus I) 1. floralis ilesosternum very much less developed laterally, intervening obli(iuely be- tween the cox;c and episternum but only slightly more so than in Anthi- cus, its outer margin not timVuiate ; pronotum constantly devoid of any trace of the subapical tubercle. (Subgenus II) Prothorax more finely and sparsely punctate, feebly and more obtusely con- stricted near the base. Prothorax very narrowly and strongly rounded at the sides near the apex. 'i. enodis Prothorax broadly rounded at the sides anteriorly, much more feebly ob- ]in. and more care should be devoted to them than is usuallv the case. Goleopffrolof/ical Notices, VL 685 wliicli produces the coDstriction as seen from above; collar short, hroad, con- stricted at base; punctures fine but strong, rather sparse, slightly larger toward base. Elytra scarcely two-thirds longer than wide, not quite twice as wide as the prothorax, widest and somewhat prominently rounded just behind the middle, broadly and obtusely rounded at apex; humeri rounded, broadly ex- posed at base; scutellar impression obsolete, each elytron transversely im- pressed at basal fifth and thence longitudinally within the humeri, the omo- plates large and distinct; punctures moderately small, strong and well separated, finer toward apex. Abdomen alutaceous, very minutely, rather closely punctate, finely and distinctly pubescent. Logs moderate in length, somewhat stout, the femora thick and clavate, the anterior more strongly so. Length 3.7-2.!) mm.; width 0.9 mm. California (San Francisco). The description is drawn from the male, the female, however, not differing perceptibly in form. In the male the pygidium is convex and snbvertical, the fifth ventral very feebly and jnst visi- bly sinuate at the middle of the apex, the genital segment well- developed, broadly, rather strongl}' sinuate throughout its apical width in circular arc, the vertical edge of the sinuation thickened and transversely foveate in the middle; the copulatory si)icule is slender, feebly impressed along its under surf^ice, gradually and very feebly dilated and thickened toward apex, the latter obtuse and circularly arcuate. A single pair. 3. H. sceiiicus n. sp.^ — Moderately stout and convex, thick, shining, pale rufo-testaceous, the head only slightly darker; elytra piceous-black, paler and more flavate in basal fourth; abdomen blackish; pubescence very short and sparse.

Elytra scarcely three-fourths longer than wide, distinctly less than twice as wide as the prothorax, the sides parallel and almost evenly, feebly arcuate, broadly obtuse at apex; humeri broadly and transversely exposed at base; sculpture and impressions nearly as in the preceding species, the surface shining. lA'gs moderate, the femora not very stout except the anterior. Length 2.9 mm. ; width 0.95 mm. Texas (Galveston); New Mexico (Albuquerque). The three specimens before me are females, and the species ma^^ be readily known from the others here described by the dull and rather densely punctate head, deep constriction of the prothorax and other characters ; the mesosternum, also, is apparently a trifle more dilated at the sides. The base of tlie i)rothorax is much broader and more dilated than in e)wdis. A^fTHICL'S Payk. Even in its restricted scope, this genus is still a large one and to some extent heterogeneous, including as it does species pf widely different facies, such as horridua^ haldemani and mari- tiTnuii. They all agree, however, in sternal, abdominal and crural structure and cannot very well be subdivided in a generic sense, although maritimus is certainly very aberrant in its oval, sub- connate elytra, with probable absence of hind wings. Coleopterological Notices, VI. 68T The genus Antliicus, as here limited, ma}- be said to comprise those species of the tribe Anthicini which have the mesosternum normal and undilated, the last joint of the antennae entire, the pronotum unmodified in structure, and the vestiture simple, — that is, consisting of a single set of hairs, disregarding in this connec- tion the erect setfe which are especially tactile in function. The last joint of the maxillary palpi is moderate in size and securi- form, and the antenntB are comparativel}' short and gradually enlarged toward apex, — never capitate as in Sapintus. It is very abundant in species throughout the United States, but, in com- 7non with all other heteromeride groups, is particularly well rep- resented in the southwestern parts of the country and in the regions bordering the Pacific Ocean.

It is not, however, for the systematist at the present time to pronounce any definite opinion concerning the status of these more closely allied species; he can only record them in order that they may be referred to by future investigators, provided with more ample data. Only those forms are here described under separate names which differ structural!}^ to a definite and obvious degree, and their true relationships will be a problem to be solved mainly by a study of life habits and interbreeding, if such subtle matters can ever be looked into.

AwuL, 1852, p. 100. This is also a very distinct species, represented at present by the unique type in the LeConte cabinet at Cambridge, Mass. It also has the body clothed sparsely with long erect hairs, which are one-third as long as the width of the prothorax, but the head is truncate, quadrate, closely and not very coarsely punctate, with a narrow impunctate line ; eyes large ; antenna^ thick, a little longer than the head and prothorax. Prothorax convex, the sides oblique, not sinuate, a little narrower than the head and as long as wide, the punctures fine but deep, even, rather close but distinctly separated. Elytra twice as long as wide, not quite twice as wide as the prothorax, the punctures strong but not re- markably coarse, separated b}'^ nearly twice their own diameters, liength 2.5 mm.; width 0.8 mm. California (San Diego). I have not had an opportunitj- to ex- amine this species for generic characters of the raesosternum, but infer that it is properly placed here, in spite of its resemblance in form to vicinus. as related by LeConte. 3. A. cribratiis Lee. — Proc. Acad. Nat. Sci., I'liila., 1852, p. 9H. Polished, pale testaceous, the elytra each with a large subcircu- lar spot at apical fourth of paler flavate, which is usually rendered tstill more obvious bj' blackish anterior and posterior margins ; p\ibescence rather long, coarse, sparse, equal and posteriorl}'^ re- curved, cinereous in color. Head coarsely punctate, with a Coleopterological Notices, VI. 693 narrow impuuctnte median line ; eyes rather large, prominent, somewhat before the middle ; antennae slender, incrassate, barely as long as the head and prothorax, the joints strongly obconical, tlie tenth snbqnadrate. Prothorax small and narrow, distinctly narrower than the head and longer than wide, coarselj^, moder- ately closely punctate. El3'tra four-fifths longer than wide, two and one-half times wider than the prothorax, gradually narrowed behind the middle and not ver^- broadly rounded at apex ; disk ver}' coarsely, deeply punctate, the punctures separated by rather more than their own diameters, much finer toward apex. Length 3.0-3.3 mm.; width 0.85-1.0 mm. California, from Sonoma to the southern parts of the State. The male sexual characters are feeble, the fifth segment being en- tirelj' unmodified on the disk and rounded at apex, the genital segment feebly sinuato-truncate throughout its width. The cor- neous sheath of the copulatory apparatus is quite simple, reduced to a flattened fillet, feebly excavated along its under surface, gradually and evenly- narrowed from base to apex, the latter ob- tusely rounded and blunt, not at all enlarged or modified ; viewed in profile, however, this corneous organ is seen to depart some- what from the usual form in curvature, for, instead of being bent downward, it is feebly bent upward toward apex, the entire organ being protruded vertically downward in normal fashion from the abdominal apex ; it is only about one-fourth as long as the abdo- men. 4. A. hecate n. sp. — Moderately stout and convex, polished, black throughout, the legs and antennte pale flavo- testaceous; elytra each with a large ill-defined spot near the base and another, rounded, at apical fourth, of testaceous, the suture also sometimes feebly suffused with a reddish tinge; pubescence long, coarse, cinereous, rather sparse but conspicuous. Head as long as wide, convex, strongly, somewhat closely punctate, with a broad smooth median line which almost attains the base; eyes large, prominent, rather before the middle; antenntc not quite as long as the head and prothorax, feebly incrassiite, the second joint short, third elongate and distinctly longer than the fourth, tenth as long as wide. Prothorax small, much narrower than the hend, exclusive of the collar not longer than wide, convex, rather coarsely and closely punctate, broadly rounded at the sides anteriorly, feebly narrowed thence to a short distance before the base where the sides become parallel; collar long and strongly developed, finely, densely punctate, finely constricted at base; basal margin subobsolete toward the middle. Elytra nearly twice as long as wide, about two and one-third times as wide as the prothorax, scarcely visibly wider behind the middle than at base, thence gradually narrowed to 694 Coleoplerological Notices, VI. the apex which is not broadly rounded ; base broadly truncate; punctures coarse and rather sparse; post-scutcllar impression broad and distinct, the omoplatoK very feeble. Ahdnmcu polished, liuely, somewhat closely punctate, the pubes- cence short and abundant. L('g>< long, very slender. Length :5.0 mm. ; wadth 1.0 mm. California (San Mateo, near San Francisco). This species is closel}' allied to crihratus, differing in its less sparse, shorter, less erect and bristling pubescence, more narrowly rounded and prominent humeri which are more transverse at base^ and in coloration. The latter is evidentl}" a development of the pattern seen in cribratus, but is ver^^ constant in the four speci- mens before me, and is equally constant in my four specimens of cribratus. 5.

The general description of LaFertc', more especially the phrase "tetedistinctement ponctuee," and the dimensions — 3.0 by 1.0 mm. — leave scarcely a doul)t that the true ephippium of that author is the species named difficilis hy LeConte; and the form described subsequentl}- under the name confasus is identical in every way. the two large series in the LeConte cabinet agreeing completely, even to the specimens which bear the type-labels. This species occurs throughout North America east of the Rocky Mountains, from New York to Texas (El Paso). Some specimens from Wyoming are feebly marked like the Californiau pinguescens, but they may be readily distinguished from that species by the sparser punctuation and rounded temporal angles. The corneous copulatory sheath is elongate, ])arallel-sided, transversely and strongly convex toward base, flattened toward apex, where it is rather abruptly narrowed in the form of a perfect ogive, the apex of the ogive produced slightly in a small promi- nent point; the lateral edges of the flattened portion toward apex are broadly reflexed. In profile the organ is straight ; the mem- branous eflferent duct beneath is large and subcylindrical. 6. A. siiuiolllS n. sp. — Polished, dark rufo-testaceous, the under sur- face of the hind body, and a large median cloud on each elytron which is a little more longitudinally developed at the sides, black; anteunai and legs ochreous-yellow ; pubescence rather long, coarse, semi-erect, sparse but cine- reous and conspicuous. Head subquadrate, a little wider than long, broadly Coleopferological Notices, VT. 695 rounded and ininiitely impressed in the middle at base, feebly convex, strongly but sparsely punctate, with a wide impunctate line; eyes moderately large and prominent, subeqnal in length to the tempora; basal angles mod- erately distinct; antennse slender, feelily incrassate, as long as the head and prothorax, the tenth joint as long as wide. Prothorax slightly narrower than the head and a little wider than long, the sides strongly roiinded anteriorly, thence oblique and feebly arcuate to basal fourth, then snbparallel to the base; disk strongly and rather closely ]>unctate; collar wide and Avell devel- oped. Elytra two-thirds longer than wide, twice as wide as the prothorax, distinctly wider at the middle than at base, the apex not broadly, evenly rounded; humeri widely rounded; omoplates very feeble; punctures coarse and sparse. Le^.s moderate in length, not very slender. Length 2.8-3.3 mm. ; Avidth 0.85-1.15 mm. Vancouver Island (Victoria). Mr. Wickham. Closely allied in general characters and coloration to ephip- pium, but distinguishable very readily b^- the much smaller eyes. The copulatory sheath is similar in form to that of r.phippium but is more gradually and acutely ogival, the apex of the ogive produced in a finer point ; on the upper surface at apex the sides are very much more narrowly :nid feebly reflexed than in ephij:)- pium. 7. A. lllteolUS Lee— Ann. Lye. Nat. Hist., X. Y., Y, p. 154; Proc. Acad., Phila., 1852, p. 99. Rather narrow, moderately convex, polished, pale ochreous- flavate throughout, the elytra sometimes very feebly clouded to- ward the middle but never distinctly fasciate; pubescence coarse, sparse, pale in color, subdecumbent and only moderately long. Head quadrate, broadly rounded at base, coarsely, rather sparsely punctate, with an impunctate line; basal angles rounded; eyes large. Prothorax slightly narrower than the head, fully as wide as long, similar in form to that of ephippiuiii but more coarsely and sparsely punctate. Elytra about four-fifths longer tlian wide, scarcely twice as wide as the prothorax, gradually narrowed be- hind the middle, the apex somewhat narrowly rounded; punc- tures coarse, rather sparse, only slightly smaller toAvard apex. Abdomen finel}^ and very sparsely punctate. Length 2.7 mm.; width 0.8 mm. California (Yuma) and Arizona (East Bridge). This form is smaller, narrower and paler than any of the others of the ephip- piuni group, and the elytral punctures are more uniform in size throughout the disk; the pubescence, also, is decidedly shorter 696 Coleopterological Notices, VI. and more decumbent. The des('rii)tion of LeConte is mis)eadin<^ in regard especially to the form of the prothorax, which does not differ from his difiicili.^ to any noticeal)le degree. 8. A. piiisiiescens n. sp. — Rather stout, convex, shining, dark piceous, the under side black; elytra pale brownish-llavate, very feebly and indefinitely clouded with piceous in an oblique spot at the middle of each ; legs and an- tennai pale; pubescence coarse, semi-erect, cinereous, not dense but consi)ic- uous. Head quadrate, as long as wide, feebly convex, coarsely, deeply, moderately closely punctate, with an almost entire median impunctate line; eyes large, prominent, the tempora straight and parallel, with the flanks flat- tened behind the eyes, about two-thirds as long as the latter; base broa mm. California (8an Francisco to Los Angeles). The male has the posterior tibiae broadly, feebly swollen witliin in basal two-thirds, the fifth ventral unmodified, rounded behind, the genital segment arcuate at tip in the middle and thence sinuate for a short distance to each lateral angle. The copulatory sheath is parallel-sided, as in the preceding species, but the tip is much more abruptly and briefly ogival, the apex of the ogive pro- duced in a broader, obtusely rounded process, the flattened superior surface at apex only ver^^ slightly and narrowly im- pressed along the obliquely rounding sides of the ogive. Six specimens. The four preceding species are mutually closely allied, and evi- dently descended from a common stock in comparatively recent times. Whether they should be termed species or geographical varieties is, at the present time, a matter of opinion ; they all differ by well marked peculiarities of structural detail, and, in the opinion of the writer, can be considered geographical varieties only in the sense that all the species of a genus are geograpliical Coleopterological Notices, VI. 697 or environmental varieties of a common parent species. Tliese four species, and probably a few others yet to be described, con- stitute a subgenus or a small and pure genus within a large and complex so-called genus, as shown by the common type of sex- ual organization. Primary sexual characters are, as far as known, exceedingly constant and permanent features, and decided ditter- ences in them should apparently indicate divergence at compara- tively' remote epochs. In fact, as before indicated, these sexual characters when ditTering decidedly in type are extremeh^ impor- tant taxonomic elements, and are often indices of generic iden- tity. This is not to say that all such genera should necessarih' receive distinct appellations at present, nor does it mean that these are the only criteria for the estimation of genera, as wo fre- quently meet with entire families, which must be split up into genera because of certain more or less apparently important mor- phological inconsistencies, in which the sexual structure is quite uniform; but it means that those groups in which the sexual structure is varied are, as a rule, the oldest and most permanently established aggregates, in spite of any accidental similarities in outward form or habitus. 9.

A much smaller species than ephippiam Laf., and distinguishable from scabriceps, to which it is closely allied, by its shorter, more oval elytra, longer and more erect elytral vestiture, sparser cephalic sculpture and several other characters. It seems to be rare and rather local. FiA'e specimens. The copulatory sheath is as simple as possible, consisting of a straight paralled-sided fillet, transversely convex above through- out and not at all impressed at the sides toward apex, the latter arcuately narrowed in a perfect ogive, with well defined angulate but unmodified tip; the under surface of the organ is deepl^^ ex- cavated throughout its entire length for the efferent duct. 12.

Head and prothorax finely, extremely densely punctate and opaque, the punctures subconfluent ; eyes rather small, at a little more than their own length from the base ; antennai somewhat thick, a little longer than the head and pro- thorax, the intermediate joints but slightly longer than wide, the tenth a little wider than long. Prothorax very slightly narrower than the head, not quite as long as wide, evenly convex. Elytra throughout as in bigutfulus, but entirely black. Length 3.2 mm.; width L25 mm. Alaska (Kenai). The above outline notes were taken from the single specimen in the LeConte cabinet. 13. A. OTicollis n. sp. — Stout, convex, somewhat shining, brownish- testaceous throughout above and beneath, the head piceous-black ; pubescence abundant, moderate and iiniform in length, semi-erect, dusky-cinereous in color. Head subcjuadrate, as wide as long, transverse, feebly arcuate and un- impressed at base, the angles broadly rounded, the tempora large, becoming gradually parallel near the eyes, the latter moderately large and prominent; surface finely, rather closely punctate, the impunctate line only visible toward base; antenna; about as long as the head and prothorax, somewhat stout, dis- tinctly incrassate, the tenth joint distinctly longer than wide. Prothorax rather distinctly narrower than the head, a little longer than wide, strongly, evenly convex, broadly rounded at the sides, the latter gradually convergent and arcuate anteriorly to the somewhat narrow collar, feebly convergent in ba sal third to the moderately wide and distinct basal margin, which is feebly 700 Goleopterological Notices, VI. expanded laterally; punctures rather coarse, deep and very close though dis- tinctly sei>arated.

Abdomen finely, somewhat closely punctate, the pubescence short and very tine. Legs moderate in length, rather stout. Length 3.;> mm.; width 1.25 mm, California (Los Angeles). Represented by a single female, having a large nubilate paler spot on each elytron at about ai)ieal third. The species is distin- guishable from higuttulus by the peculiar form of the prothorax. A male, taken in southern California by Mr. Dunn, is placed with this species for the present, although it (lifters in having a relatively larger, more elongate and less medialh' rounded pro- thorax and nari'ower bodily form ; it is similar, however, in color- ation, being pale, with the head black. This specimen is the only one befoi'e me of the biguttulus gi'oup which has the male organs in auy way protruded, and even here they are only partially visi- ble; the copulatory sheath has the sides straight and gradually convergent at apex, the immediate tip of the latter prolonged in a narrow acute point ; the excavation of the under surface con- tinues to the extreme acute apex, becoming canaliculate along the produced spiculiform portion ; the portion visible is perfectly straight in profile. 14.

Readily distinguish- able from ovicollis by the larger, more anteriorly rounded pro- thorax, denser punctuation of the head and some other characters. The male has the fifth ventral but slightly longer than the fourtl;. unmodified and very broadly rounded behind, the genital segment coriaceous, large and wide, broadly arcuate throughout at apex and with a small rounded indentation at the middle of the disk. Two of the specimens depart noticeably from the usual form and represent, either aberrations, or structural varieties. The first — taken in the valley of Redwood Creek, Humboldt Co., where the normal form also occurred — has the punctures throughout much coarser and sparser and the prothorax smaller, shorter, more broadly rounded at the sides, and widest only a little before the middle ; the second, a unique taken in Sonoma Co., has the punc- tuation normal, but the prothorax is smaller, more broadly and posteriorly rounded, and the head has a narrow but distinct and entire impunctate line; they are both females. 15.

The posterior trochanters are fiiiel}' spieulate posteriorly in the male, and this very distinct species is, for this reason alone, as- sociated with higuttulus ; that it realh' has but little affinity, is however shown by the male sexual characters, wiiich are wholly different. The fifth ventral is broadly rounded, but slighth^ longer than the fourth, and unmodified, the genital segment corneous, feebl}^ and rather broadly arcuato-truncate at apex, with its surface transversely impressed posteriorly. Only the apical part of the copulatory sheath is visible, but this is modified so as to no longer serve as a protective sheath, but simpl}^ as an anchor ; it consists of a slender parallel-sided shaft, having at the apex a perfect and strongly developed double barbed cordiform enlargement, the lateral lobes of which are obliquely prominent posteriorly ; viewed in profile the barbed point is arcuate downward, with its ex- treme tip acute. 16. A. protectllS n. sp. — Elongate, convex, polished, variable in color from pale brownish-testaceous, with or without the head black — generally male, — to black throughout the body and legs, with the antennse paler toward base — generally female ; elytra each with a small pale spot behind the middle, which is frequently obsolete; pubescence moderate in length, coarse and .abundant.

The single female represents a species allied rather closely to biguttulus, but departing structurally in its stouter thicker body, and much coarser and sparser punctuation of the head and pro- notum. There is before me another female, taken b}' Mr. Dunn at El Paso, Texas, which I refer for the present to this species, although it differs to a great degree in color; it is black through- out, the legs paler, the pronotum paler in basal half, the elytra testaceous, with the basal margin, a large uneven median and smaller subapical fascia, black, the last two enclosing the usual pale spot, which is not at all suggested in the type of solidus; the prothorax, also, is noticeably shorter, being not longer than wide. 18.

It is possible that the elytra ma^- haA'e been accidentally denuded in this speci- men, but it is difficult to imagine how this could have been ef- fected so uniformly, not a single'long hair remaining, except the usual series af erect tactile setie along the flanks toward base. 19.

California, from the southern parts of the State to Siskiyou ;. also at Lake Tahoe. The pronotum is generalh' broadly and feebly impressed along the median line, especially' anteriorly. I obtained a large series at Gilroy Springs. The coi)ulatory sheath is of peculiar form ; it is rather stout,, and, when viewed dorsally, has the sides straight and gradually Coleopterological Notices, VI. 707 convergent from base to apex, the latter narrowly truncate, with a small and very short truncate median projection, the surface strongly and transversely convex throughout ; on the under sur- face it is broadly and deeply excavated throughout its length, the side walls projecting inward and prominent at basal fourth ; in profile the entire organ is strongly and evenly arcuate down- ward from base to apex. The fifth ventral is unmodified, broadly rounded at apex, the genital segment rather small, flat, short and trapezoidal. 23. A. decrepitus n. sp. — Moderately stout, the elytra somewhat de- pressed, polished, black, the entire under surface, legs and antennae rufo-testa- ceous; pubescence moderate in length, somewhat dense, cinereous and con- spicuous.

Abdomtn polished, coarsely reticulate in fine lines, the punctures very feeble. Legs moderate in length, slender. Length 2.4 mm. ; width 0.75 mm. Oregon (The Dalles). Mr. Wickham. This species is remarkable, among its associates of the present group, in the form and small size of the prothorax, the constric- tion being at a greater distance from the base than usual ; it re- sembles cephalotes, but differs greatly in its smaller head and pro- thorax ; in decrepitus the basal width of the latter is almost equal to its maximum width. The sex of the single specimen in my cabinet has not been determined. 24. A. Iliercurialis n. sp. — Somewhat slender, the elytra slightly flat- tened, shining, dark piceous-brown or paler, the paler forms frequently with a large nubilate and slightly paler spot on each elytron at ajfical foui'th, and also paler near the base; antennaj throughout and legs rufo-testaceous, tlie femora darker; pubescence stiff but short, rather abundant, pale yellowish- cinereous and distinct.

Elytra somewhat more than three-fourths longer than wide, twice as wide as the prothorax, the sides parallel, evenly and feeblj' arcuate, the apex not very broadly rounded; scutellar impression broad and distinct, the omoplates almost obsolete; punctures strong and close, nioderatelj' coarse, very much finer toward apex. Abdomen alutaeeous, minutely, extremely densely punctate and finely reticulate, more shining and distinctly punctate toward base. Le(/!< moderately short, slender, the femora minutely and densely punc- tate. Length 2.9 mm.; width 0.8-0.9 mm. California (Mendocino, Humboldt, Lake and Sonoma Cos.). It is possible that there nia^- be some closely allied species in- termingled in the large series before me, but they cannot be ad- vantageously separated at present. This species is closely allied io punctidatui< and is similar in the male sexual characters, but it is somewhat more slender, with less elongate elytra, more finely and much more densely punctate head and prothorax, the latter relatively' narrower, and is never black, while of the numerous specimens of punctulatus which I have taken, none are pale and the two forms are never found in the same locality. The el3'tra are impressed along the sutural margin toward apex, esiDecially in the male. A single female from Tahichipi Pass is associated with mer- curialis for the present, but it almost certainly represents a dis- tinct and decidedly stouter species. 25.

Length 2.2-2.7 mm. ; width 0.7-0. i)5 mm. Entire I'nited States east of the Rocky Mountains, from Idaho (Ca'ur d'Alcnej to New York, Texas and Mississippi. This species is so common and well known that further description would be superfluous in this imperfect revision. Coleopterological Notices, VI. *r09 The copnlatory sheath is long, moderately stout, only feebly arcuate from base to apex, parallel-sided and transversel}^ convex from a dorsal point of view, gradually narrowed in a long simple ogival and not very acute point in apical third, the under surface deeply excavated throughout, the walls projecting strongly in- ward at basal fifth or sixth. It is thus of the same type as in punctulatus, but is parallel, more pointed and much less arcuate. 26. A. ^ileiisis n. sp. — Moderately stout, convex, rather dull, rufo-ferru- ginous, the abdomen blackish; elytra with a feeble and nubilate blackish fascia at the middle and a paler subapical spot as in cervinus, both frequently obsolete.

Abdomen rather dull, the legs very pale; femora somewhat stout. Length 2.2-2.7 mm.; width 0.7-0.9 mm. Arizona (Tucson). This species is closel}^ allied to cert'^nMS, differing in its stouter and more incrassate antennae, broader head which is broadly im- pressed in the middle at base, and in its still larger eyes. The copulatory sheath is nearly similar to that of cervinus, but is more gradually narrowed to an obtuse ogival point in more than apical half; the efferent duct is stout, but becomes rapidly and obliquely pointed toward apex. 27. A. praeceps n. sp. — Moderately stout and convex, shining, black tlu'oughout beneath, the head and pronotum picescent; elytra dark rufo-tes- tiiceous, becoming flavate toward base, along the apical margin and in a rounded spot near apical fourth, the surface blackish before and behind the spot; antenna; and legs throughout pale flavate; pubescence cinereous, rather coarse and abundant, somewhat long on the elytra. Head fully as long as wide, parallel, broadly arcuato-truncate and unimpressed at base, the angles rounded; tempora becoming parallel for some distance behind the eyes, the latter moderately large, prominent; punctures fine but strong, rather close, the impunctate line feebly defined ; antennie distinctly shorter than the head and prothorax, somewhat stout, feebly incrassate, the tenth joint scarcely as long, as wide.

Tins con8i)icuous species bears a striking superficial resem- blance to ci'ibi^atus Lee, but belongs to the curvinus group, hav- ing the head truncate at base. The single male before me has very feeble sexual characters, and the spicule is not at all pro- truded. 28. A. seniiiiotatlis n. sp. — Kather narrow, moderately depressed, shin- ing, pale rufo-ferruginous, the under surface of the hind body blackish ex- cept toward the abdominal apex; elytra each with a rounded and feebly de- fined flavescent spot at apical fourth, the adjacent surface just visibly pices- cent; pubescence short, moderately dense. Head well developed, quadrate, as long as wide, feebly convex, finely, rather closely perforato-punctate, Avith an ill-defined imijunctate line; base truncate and unimpressed toward the middle, the angles rounded; tempora long, parallel, the eyes somewhat small but prominent; antennae short, rather slender, feebly incrassate, the tenth joint not quite as long as wide. Prothorax quite distinctly naiTOwer than the head, as long as wide, formed nearly as in cerchius ; punctures fine and close.

New Mexico (Coolidge). Mr. Wiekhara. The peculiar form of the prothorax, which in this and the two succeeding species reminds us somewhat of Yacusus, w'ill render the identification of them comparatively eas}'. The present form differs from ancilla in its much larger size, and in other cliaracters which will be noted below\ 30. A. ancilla n. sp. — Somewhat convex, moderately stout, feebly shining, black throughout, the legs rufo-piceous distally; antennfe dark rufo- testaceous throughout; pubesence somewhat short, jdumbeo-cinereous, moder- ately dense.

The sex of the t^'pe is not determined. Ancilla is an ally of parallelns, but differs in its smaller size, more convex surface, shorter antenna?, smaller and less prominent eyes and black color. 712 Coleopterological Notices, VI. 31. A. sodalis ii. sp. — Broad and stronjilv dejuesspd, rather shininji, black throufihoiit, the femora piceous; tibise and tiirsi pale testaceous; antenna' pale throughout, sometimes piceous distally; pubescence tine, short, even, plum- beous and somewhat sparse.

Length 3. 1-3.2 mm. ;^ width 10-1. 2 mm. Indiana. A very distinct species, to be readily known b}- its broad de- pressed form, peculiar outline of the prothorax, coarse cephalic sculpture and other characters. It seems to lead quite naturally to the peculiar group of spotted species which follows. The sex of the two specimens before me is not determinable. 32. A.

Abdomen dull, minutely, strongly and extremely densely punc- tate. Legs rather long, stout. Length 4.0 mm.; width 1.3 mm. Iiuliaiia. This is a fine species, one of the largest of the genus, and is not closel}' related to an\^ other. The male has the fifth ventral feebly truncate at apex and slightly flattened on the disk toward the middle, the genital segment rather small, trapezoidal, with the somewhat narrow apex emarginate in circular arc throughout, the copulatory sheath stout, gradually narrowed to a blunt point, straight in profile, and, in general structure, ver}' simple, re- sembling somewhat that of ce?'i5m»6'. Two specimens. These quadrimaculate species form quite a distinct and natural group by themselves, and have the four elytral spots remarkably constant in form and size through long series. These spots are evidently due to protective mimicry, possibly of some species of Bembidion, and have therefore been gradually evolved by natural selection ; their constancy is easil}^ accounted for in this wa}'. 33.

There is only a single specimen before me, but I have faileil to observe any variation in color, in allied species which are represented h\ good series, similar to that reported of this by LeConte, and think there must have been some confusion of species. 714 CoJeopterological Notices, VI. 34.

This is a very small and rather remarkable species, which is probably more nearly related to cei'vinus than to those with which it is here associated. The fifth ventral of the male is unmodified ; the genital segment is large, coriaceous, very broadly arcuate throughout its width, not impressed ; the copulatory sheath seems to terminate in a slender parallel-sided shaft which is abruptly and transversely enlarged at tip but scarcely barbed.

With the typical forms of this species, I have placed numerous aberrant or varietal forms from New Mexico, Iowa and Montana; some of them are larger and stouter with longer pubescence ; others have a large piceous cloud on the eh tra. There certainly seem to be some closely allied but distinct species involved, which can only be successfully studied with larger series from numerous localities, 53.

California Tliis small and inconspicuous species is sufficiently differen- tiated from the preceding by its short elytra, small and more rounded prothorax, and other characters as heretofore stated.

The species in this particular part of the series are so closely allied and apparently so indefinite, that I can only select at pres- ent a few of the more obviously distinct ones for description as landmarks ; much more extensive material will be required to enable the future reviewer to fully differentiate them. 55. A. iiilliidlis n. sp. — Moderately narrow and convex, shining, rufo- testaceous, the entire under surface of the hind body black; elytra black, with two large humeral areas meeting near the scutellum, and two oblique oval apical spots meeting on the suture at apex, of palerufo-testaceous; pubescence rather long, coarse, cinereous and conspicuous.

Length 1.75-1.85 mm. ; width 0.6 mm. This species, which has been carefull}^ described by LaFerte, is widespread in distribution, the series in my cabinet being from Kansas, Lake Superior, North Carolina and Pennsylvania ; it is recorded b}^ LeConte also from Boston, Mass.

The male sexual characters are somewhat feeble; the copulatory sheath is very broadly' and circularl3' rounded at apex, longitudinally impressed along the middle dorsally, and broadly excavated beneath. LaFerte's measurements appear to be care- Coleoijterological Notices, VI. 729 fully made, and are a decided aid in identification ; otherwise his description of this species is very superficial. There is another Florida example before me, agreeing nearly with ictericus, but having the eyes larger and less convex, the prothorax relatively larger and the elytra more elongate. 58.

One of the most aberrant species of Anthicus, because of the perfectly oval elytra without trace of humeral angles ; it is quite local in habitat. This is possibl}- the species erroneousl}- identified b}' Dr. Horn in his recent catalogue of the Coleoptera of Lower California (Proc. Cal. Acad. Sci., 2, lY, p. 355), as ictericus Laf., the mari- timus Lee. of Horn probably being any one. of the larger species with triangular head, here referred to the genus Ambl^'derus of LaFerte. These last bear onlj- a feeble superficial resemblance to the true maritimus, and cannot be associated with it systemati- calh'. It is almost needless to add that there is no resemblance whatever between maritimus and ictericus, which latter does not occur near the Pacific coast, and the same remark applies to A. sturmi Laf. (elegans), which, as far as known, inhabits the austral regions of the Alleghany Mountains only. The Notoxus monodon, of Dr. Horn's list, is constrictus Csy.* Notes. Anthicus lecontei Chmp., from the Pacific coast of Guatemala, is said by the author to occur also in Arizona, but I have not been able to recognize it. From the description and figure it would seem to be most nearlj' allied to stellatus and saucius, from the northern parts of the United States. A. squamosus Laf., is said by Mr. Champion to be a Mexican species, and, as the type of A. luguln'is came from the same source and cannot be identified among our species, it seems best to re- *It may be stated further that the Trichoharix trhwtata Say, of this list (1. c, p. 358), is either compacta or mucorcu — species wliich are Avidely different from trinotttta. Coleopterological Notices, VI. 731 gard it also as Mexican ; these two species might therefore be appropriately stricken from our lists. A. impressijyennis Laf., is evidently not an Anthicus, but will constitute a genus perhaps allied to that including the Mexican dr-omedarius, but the comparatively simple prothorax, impressed inflated elytra and glabrous integuments form a singular combina- tion, which prevents us from assigning it an}' deiinite position. A. exilis Laf., is another very peculiar species, which cannot be retained in Anthicus, and Avhich is likewise undeterminable in its aflSnities. A. jMllidus Say, remains unknown. A. jjolitus Say, is more probabl}' a xylophilide than an Anthi- cus, but is completely indeterminate and may be a Tachys or some chrysomelide. A. csesiosignatas Boh., is said to be from " Puna "Island, Cal., and difters completel,y in type from an^^thing known in the United States. Puna Island is off the coast of Ecuador, and it would be perfectly safe to omit this species from our catalogues in the future. A. troglodytes Boh., likewise differs altogether in tj'pe from any known North American species and should be omitted ; it is said to occur at San Francisco and in " Taiti." A. amplicollis Boh., said to occur at San Francisco, differs com- pletel}^ in type, as in the two preceding cases, and is evidently not North American ; it should also be omitted. A. nitidas Boh., seems to be allied to nitididus Lee, but can- not l)e identified with any of our species, than which it is much smaller (1. 'i^ mm.; w. f mm.); San Francisco. A. atomarius Boh., does not appear to differ from nifidus ( 1. 2.0 mm.; w. f mm.); San Francisco. As these two species have a North American habitus, they might be retained in the lists until their identity can be determined. Mr. Champion very kindly sent me, some 3'ears ago, a number of typical representatives of species described or quoted by him in the Biologia Centrali-Americana, and upon these it seems de- sirable to remark as follows : — A. aspJi(iHini(><, 2ii>>icfip''>t»i>< find occidcntaliH Chmp., iire members of the genus Lappus, but constitute one or two distinct groups, because of marked peculiarities in occipital structure.

A. exiguus Chmp., seems to lie bet^veen the nanus and ictcrieus gi'oups of true Anthicus, but is altogether distinct from any of our numerous small species. A. dromcdnr'ms Laf., -will form the type of a distinct and still unnamed genus, allied to Malporus, but with a far greater extension of the mesosternura and complete absence of long erect tactile setaj. A. spinicMis Laf., is also the type of a distinct genus, named Acanthinus by LaFerti!' (Mon., p. 136), and characterized by a great lateral extension of the mesosternum and subseriate elytral punctures; the genus extends into southern Texas. SAPIXTUS n. gen. While it is true that the species separated from Anthicus un- der this name appear to possess no very radical structural modi- fication, there are so many minor points of divergence, and the species are so evidently homogeneous among themselves, that I have no doubt of the necessity for the division, especially as these differences are accompanied by a marked peculiarity of general habitus. The body is stouter than in Anthicus, with relatively much longer el3'tra and smaller prothorax ; the elytral epipleurre are wider, the first joint of the hind tarsi is longer, and the corre- sponding tibial spurs are shorter and much more slender, some- times apparently almost obsolete. The vestiture is quite differ- ent, consisting of two distinct sets of hairs, besides the erect tactile setic, the longer and more erect hairs arising from the coarse punctures, the shorter and generally more decumbent pubescence from minute punctules scattered over the interspaces. Finally, the antenniB terminate invariabl}- in an abrupt, though feeble, three-jointed club. In fact Sapintus appears to constitute a true genus, and can in no wise be regarded as a subgenus of Anthicus ; it is confined geographically to the United States east of the Rocky Mountains, extending well into Mexico, and is rep- resented in the arid Sonoran province by one peculiar species ; it does not occur at all in the true Pacific coast fauna. The species can be distinguished among themselves as follows: Eyes large and rather strongly convex, the body usually stouter. Body T)lack or l)rownish-black. Legs blackish.

Elytra very large, three-fourths longer than wide, fully two and one-half times as wide as the prothorax, par- allel and feeblj' arcuate at the sides, the apex circularly rounded; humeri very widely exposed at base; post-scutellar impression distinct, the omoplates feeble ; punctures very coarse and deep, well separated, becoming finer toward apex.

Rhode Island, New York and Iowa (Iowa City and Independ- ence). The paler coloration assigned by LaFerte is probabl}^ due to immaturit}', as this is without ranch doubt the species de- scribed by that author, and is one of the largest of the genus. The male sexual characters are pronounced, the anterior coxoe being posteriorly spinose, the anterior tibise slightly bent inward toward apex and densely clothed with short stiff hairs, the fifth ventral with a short, broadly rounded and abrujjtly porrect lobe at apex which is finely and transversely impressed at its base, the genital segment coriaceous and broadly sinuate, and the cop- iilator\^ spicule short, slender, with an elongate and feebly dilated, evenly and acuteh' lanceolate tip. 2.

The single specimen in my cabinet seems to be a male, judging by the ex- posed pygidium ; it has the anterior coxre angulate behind and the corresponding tibiffi not bent but densely clothed with short stitf setse within toward apex, the intermediate trochanters and tibiae not modified, the fifth ventral long, evenly and almost semi- circularly rounded, unmodified on the disk and about three-fourths longer than the fourth. This form of the fifth segment is very different from that of hisjndulus, and in fact throughout the present genus the species, which generally resemble each other very strongly or adhere to a common type of structure, differ strikingly among themselves in the secondary sexual modifica- tions of the male. There are several points in the original description of pusiUus, which give rise to grave doubts concerning the identity of the present species. For example, the phrase " les yeux tres-peu saillants," will not accord with this form, nor with any other of the genus known to me; also "corselet retre'ci faibleraent et progressivement depuis les pommettes, qui sont pen saillantes, jusque'a la base, qui ne parait nullement marginee ; " finally " el3' tres presque trois fois aussi larges que le corselet et plus de deux fois aussi longues que larges en oval tres-allonge posterieurement." The length and width are given as 2.0 and O.fi mm., respectively; that is, if these measures are correct, the in- sect is proportionally much more slender than any other of this pai-t of the genus, and yet the elytra are nearly three times as wide as the prothorax.

The four specimens before me vary greatly in size as is usual in this genus, and the description is drawn from the male, this sex having the anterior tibiae very strongl}' arcuate aijd pubescent within, the intermediate more apically and less strongly arcuate, the anterior trochanters feebly and obtusely prominent behind , the intermediate unmodified, the fifth ventral moderate in length and evenly rounded behind, unmodified or only slightl}' flattened on the disk. The female has the prothorax smaller, and the elytra shorter and relatively broader, and, in one specimen, completeh^ infuscate except toward the humeri and sides before the middle. 9.

This species, which is represented b}- a single male, is closel}^ a,llied to festinans, but ditters in its smaller prothorax which is much more broadly margined at base, in its feebler and closer elytral punctures and in the sexual characters. The anterior and intermediate femora are distinctly arcuate toward apex, but the trochanters are unmodified, the fifth ventral moderate in length, rounded or feebly subtruncate at apex and unmodified on the disk. The elytra completely lack the strong and conspicuous subapical impressions near the suture which characterize the male of festinans. 10. S. tiiiiidil!^ n. sp. — Slightly stout, convex, shining and rufo-testa- ceous throughout; pubescence of the head and pronotum very short, stiff, strongly arcuate and not dense, intermingled on the latter with some long tactile setae, on the elytra short, stiff and strongly arcuate, longer, straight and finer near the suture, the short hairs extremely minute but very coarse, the vestiture not dense and pale throughout. Head transverse, convex, not dis- tinctly punctate, rectilinearly truncate and unimpressed at base, the angles broadly rounded, the tempora becoming parallel just behind the eyes which are rather small, convex and prominent, situated at much more than their own length from the base; antennce somewhat longer than the head and pro- thorax, slender, the three outer joints broader but not in the least darker in color. Prothorax rather large, convex, only slightly narrower than the head, not quite as long as wide, broadlj^ rounded and widest just before the middle, the sides becoming strongly convergent and feebly sinuate toward base, the latter strongly margined and not more than three-fourths as wide as the disk; punctures fine and well separated, dense in the middle toward base. Elytra scarcely more than two-thirds longer than wide, not distinctly more than twice as wide as the prothorax, the sides parallel and very feebly arcuate, rather narrowly rounded behind in apical third; humeri rounded, widely ex- posed at base; scutellar impression and omoplates obsolete; punctures rather small but deep, only moderately sparse. Abdomen somewhat shining, obso- letely punctulate. Zeiy.s moderate in length, somewhat slender. Length 2.1 mm.; width 0.7 mm. Florida. The single male represents a species widely diflferent from any other here described in its peculiar vestitui-e and subglobular pro- thorax. The legs and trochanters are not perceptibly modified, but the fifth ventral has a peculiar discal excavation ; the pos- terior edge of the segment is quite evenly rounded, but thick and deep vertically, and the large rounded impunctate pit at the middle of the disk thins out the vertical posterior edge into a flat 742 Goleopterological Notices, VI. translucent plate. The genital segment is moderate in size, smooth, polished, even and pale in color, with the apex trans- versely truncate. The other organs are not visible in the type. AMBLYDERIS Laf. The American species referred to this genus apparently ditter in no essential particular from the North African types of La- Ferte, the tubercles along the crest of the subapical declivity of the pronotum being however always inconspicuous. Amblyderus is without doubt a perfectly valid genus, and will prove to be a tolerably large one in the colder parts of the eastern United States and in the true Pacific coast faunal region, where its mem- bers constitute one of the most characteristic elements of the sea- beach population. The eight species here deemed worthy of description may be recognized as follows : — Species of the Pacific Coast; elougate-oval, very convex, densely clothed Avith short coarse decumbent pubescence; tubercles and punctures of the prono- tum indiscriminately intermingled and apparently mutuallj' indepen- dent. Larger species, not under 3 mm. in length.

Head triangular, slightly wider than long, rather de- pressed, the base transversely truncate or even very feebly sinuato-truncate but not distinctly impressed; tempora narrowly rounded, very prominent; eyes large, convex, at about three-fourths of their ovvn length from the base; disk finely and closely tuberculose, with a wide smooth median line toward apex; antennaj scarcely one-half longer than the head, somewhat slender, moderately incrassate, the tenth joint sliglitly wider than long, eleventh only slightly longer than the tenth, rounded, obtusely jwinted. Proihorax trans- versely trapezoidal, distinctly wider than the head, widest and more strongly rounded near the apex, the sides thence convergent and broadly, evenly arcu- ate to the basal margin which is distinct and cylindrical for a short distance to the base; apex transversely and very feebly arcuate, nearly one-half wider than the base; disk finely, closely tuberculose, also minutely punctate, abruptly declivous and very feebly concave toward the middle anteriorly, the summit of the declivity not more strongly tuberculose; median line slightly impressed. Elytra sulioval, very convex, scarcely more than one-half longer than wide, a little more than one-third wider than the prothorax, the sides subparallel, evenly and strongly arcuate; apex somewhat narrowly subtruncate; sides toward base evenly rounded almost to the ijrothorax, the base broadly sinuate, the basal parts of the humeri very narrow and strongly rounded; disk finely, closely punctate, without impressions or omoplates. Ahdomen dull, strongly reticulate, finely but strongly, densely punctate. Legs as i,n Anthicus, mod- erately long, thick. Length 3.1-3.8 mm.; width 1.25-1.4 mm. California (San Francisco). The male has the anterior tibiiv thick and strongly, inwardly arcuate toward apex, the fifth ventral rounded behind and un- modified, the genital segment large, corneous, black, truncate at apex and transversely, unequalh' impressed throughout the width ; the copulatory spicule is broad and stout, but rather abruptly narrowed near the apex and prolonged in a slender straight pro- cess which is very strongly compressed and vertically laminiform, the apex slightl}' swollen vertically' and obtuse in profile. This is one of the largest, and, with the exception of Tanar- thrus .Halinus, probably the bulkiest s])ecies of the tribe in North America. I have taken it in large numbers on the sandy sea- beaches near the city. 744 Goleopterological Notices, VI. 2.

Prothonix transversely trapezoidal, widest and more narrowly rounded near the apex, dis- tinctly wider than the head and throughout nearly as in ohcsiis, except that the punctures are fine and strong and the intermingled tubercles generally smaller and si)arser. Elytra not quite one-half longer than wide, nearly one-half Avider than the prothorax, oval, slightly attenuate behind, the apex not very broadly subtruncate ; sides strongly arcuate, more rounded at the humeri, the latter very narrowly exposed at base ; punctures rather fine but strong and close-set. Ahdomcri finely but strongly punctate, the punctures distinctly separated; pubescence coarse, the legs stout. Length 3.0-3.2 mm.; width 1.25 mm. California ( sea-beaches of Los Angeles Co.), Mr. Wickham. The male has sexual characters of the same type as in obesus, except that the genital segment is pale in color and more coria- ceous ; the copulatory sheath is not protruded in any of the types. This species is allied to obesus, but differs in its more feeble sculpture of the head and pronotum, in its shorter and more rounded elytra, smaller size, and very pale coloration, the integu- ments being diaphanous. In both this and the preceding species the elytra have each a short canaliculation along the suture near posterior third, -which is common to both sexes. Four specimens. A female before me seems to represent a distinct species allied to the above ; it is entirely pale, with the sutural bead blackish and the elytra longer, with the punctures larger, stronger and more impressed. This specimen has a deep fovea-like impression behind the left hind coxa, of which there is no trace on the right side, but is not deformed in anj'^ other wa^'. 3. A. parviceps n. sp. — Moderately stout, very convex, feebly shining, dark rufo-tcstaceous, the under parts of the hind body and the elytra in great part suffused with blackish; pubescence moderate in length, coarse, somewhat dense, recumbent, cinereous and distinct, without trace of erect seta-. Head very small, triangular, al)out as long as wide, feebly convex, closely covered with fine punctures and small tubercles, the smooth median line wide ante- riorly, becoming narrow toward base but entire; eyes moderataly large and Coleopterological Notices, VI. 745 convex, at scarcely' more than their own length from the base; tenipora very prominent, rounded; base transverse, the subvertical basal wall feebly im- pressed toward the middle; antennae nearly as long as the head and prothorax, moderately incrassate. Frothorax transversely trapezoidal, at least one-third wider tlian the head ; sides convergent and arcuate from near the apex to the basal margin; apex transverse, feebly arcuate, nearly one-half wider than the base; surface closely covered with small punctures and tubercles, the median line impressed toward apex. Elytra elongate-oval, two-thirds longer than wide, two-lifths wider than the prothorax ; sides evenly arcuate; base broadly sinuate, the apex equally broadly subtruncate; humeri narrowly exposed at base; disk evenly convex, finely, not very closely punctate, without further modification, except the subsutural impressions at apical third W'hich are fee- ble. Abdomen dull, densely reticulate, finely punctate, rather sparsely and coarsely pubescent. Legs somewhat long and not noticeably stout. Length 2.6-2.8 mm. ; width 1.0 mm. Californifi ( southern ). Mr. H. C. Fall. The apical declivous surface of the pronotum is distinctly and transversely concave, but its upper crest is not more strongly tuberculose. The male has the anterior tibi;c bent, the fifth ven- tral feebly sinuato-truncate at apex but otherwise unmodified, the genital segment moderate in size, pale, truncate, and transversely and unequally impressed, the copulatory spicule with the tip ab- ruptly'' narrowed and produced in a shoi't slender acute point, which is subcylindrical and not noticeably compressed. With the two males which I received from Mr. Fall, I have as- sociated a single male from Alameda Co., which does not seem to differ specifically. 4. A. gracileiitll!>i n. sp. — Rather narrow but strongly convex, some- what shining, pale rnfo-testaceous, except the abdomen and elytra, Avhicli are slaty -black ; pubescence recumbent, coarse and dense as usual.

Abdomen alutaceous, minutely punctate, finely pubescent. Lega moderate in length, somewhat stout. Length 2.4 mm. ; width O.i^ mm. California (near San Francisco). The narrower form, still smaller size and relatively- larger head will readily distinguish this species from the preceding. In the male the anterior tibiit are bent toward apex, the fifth ventral feebly sinuato-truncate at apex but not otherwise modified, the genital segment thin, broad, truncate at apex, strongly and trans- versely impressed, the surface bent downward toward apex throughout ; the copulatory spicule is abruptly narrowed near the apex and produced in a short slender process, which is gradually bent upward and not compressed ; the efferent duct beneath the spicule is broad, flat, transversely truncate at tip, bent first down- wai'd then upward and projects in the t3-pe specimen far beyond the corneous spicule. 5.

This species is distinguishable by its very short truncate e\y- tra, and differs from every other in having the elytral pubescence streaming out perpendicularl}' from the suture in basal third and inner half. The exposed part of the tergum consists of a very large convex, finely and sparsely punctate segment, para- bolically rounded behind and having, near the base, two trans- verse and densely pubescent patches nearly trisecting the width, analogous perhaps to those of the Omalini or at least similar in origin and purpose.

Elytra short, one-half longer than wide, one-half wider than the prothorax, connate throughout, semi-circularly rounded behind in fourth or fifth, the sides parallel, not wider behind the middle than at base; humeri widely exposed at base; disk not at all modified at base, very feebly convex, minutelj^, densely punctate, the suture somewhat elevated behind. Abdomen coarsely, sparsely pubescent, the legs moderately long and slender. Length 3.0 mm. ; width 0.75 mm. Utah (Great Salt Lake). A distinct species also represented before me by the female only, this sex having the exposed part of the tergnra feebly con- vex, parabolic at apex, and with a minutely pubescent and nar- row line near the base, extending almost entirely across the disk and narrowly interrupted in the middle. 4.

Closely allied to salicola, but distinguishable by the elytral sculpture, smaller eyes and more swollen and more prominent tempora; the tip onl}' of the tergum is exposed in the female, and 754 Coleopterological Notices, VI. this is rather closely punctured .ind pubescent. The epistoma is short, the suture distinct and broadly angulate, the basal three- fifths corneous and sculptured like the adjoining front, the apical two-fifths abruptly thin, transparent and devoid of sculpture. 5.

The male has the fifth ventral not quite as long as the fourth, broadly truncate at apex, the truncature broadly and feeby sinuate in the middle. The under surface of the hind body in tricolor is very pale throughout, the abdomen being rather more closely punctate than in salicola, and, as usual in this section, there are two longitudinal series of long tactile setffi, two setae to each segment. The dusky tip of tlie el^'tra, re- ferred to in the original description, is due to the black apex of the abdomen by diaphaneity; in the following species, however, the ti}) is really l)lack. 6.

The description is drawn from the male, this sex having the fifth ventral rather shorter than the fourth, broadly truncate at apex, with a very feeble sinuation and with a slightly thickened bead-like edge toward the middle ; only the p^'gidium is ex- posed at apex. Besides the denser, more opaque and differently ornamented elytra, this species differs from salicola in its relativel}' smaller head and coarser sculpture of the pronotum. 7. T. alutaceiis Lee— Ann.

This genus contains luimerons species in North America, but is more abundant in the temperate than in the troi)ical regions of the continent. The thirty-two species included in the table be- low, appear to be rigorously definable and without suspicion of intergradation, as far as can be observed Avith the abundant ma- terial before me. The species in fact seem to be unusually con- stant through long series, in the majority of cases even in colora- tion, and types of coloration have proved so stable that it is found convenient to divide the genus into groups based primarih^ upon these characters. It seems evident, moreover, that this may be as natural a grouping as ^ny which can be provisionally assumed. The thoracic hoiii is another character heretofore regarded as especially prone to variation, which I have found to be quite con- stant in general form and structure within the same sex of the various species, and this is what might be anticipated from analog^'. It is true that the horn is an unusual and greatly developed struc- ture of scarcely' obvious utility in the economy of the animal, if we consider the genus in relation to the other genera of An- thicini; but, on the other hand, we must remember that within the large genus Notoxus, the horn, wiiatever its use, whether a \)vo- tection for the head or something more obscure, is a remarkably characteristic generic feature, and consequentl3^ a long established and permanent structure, and ought not to possess much specific variabilit}' at the present time. The species may be readily recognized as follows : — Elytra entirely black, sometimes feebly and indefinitely paler toward the apex 2 Elytra black, cacb witli two lai-jjce obli(|ue spots of pale tint 3 Elytra black, crossed by two pale fascia; 4 Elytra more or less i)alc, with a sinj^le dark fascia behind the middle, Avbich is generally produced anteriorly along the suture to a greater or less de- gree, fre< Laf., subtilis Lee.) talpa Laf.

Crest completely obsolete, the posterior fascia large and enveloping the apices; median fascia greatly prolonged along the suture, becoming bifurcate; elytra without erect setae planicoriiis Laf. The characters of planicornis, which is the only species not before me, are taken from the figure given by LaFerte; this figure does not, however, at all agree with the description, which states that there is a small scutellar spot, a median sinuous fascia and another ante-apical, which is composed of two lunules ; this would make the markings agree nearly with those of delicatus, but as the description states that there are no " polls raides " in planicornis, and as these ai'e very evident in delicatus, I prefer to regard the two species as distinct for the present. As I have before explained (Bull. Cal. Acad. Sci., I, p. 333), delicatus is in no way closely related to monodon or jnlatei. I have considered pilatei and decoloratus of LaFerte as varities of monodon for the present, as I have not been able to identify them, but it is more than possible that they represent valid species. The genus having been so recently reviewed by Dr. Horn (Tr. Am. Ent. Soc.,XI, 1884, p. 165), it is only necessary at the present time to describe the species announced as new in the above table. X. Ibalteatiis. — Moderately stout and shining, rufo-piceous, the elytra black with a broad and even transverse fascia at basal third, and another, equally straight and transverse but narrower, at apical third ; basal margin and apex also paler; vestiture very fine, short, even and only moderately close anteriorly, coarser and denser on the elytra, where it is pale cinereous on the pale bands, elsewhere brownish, without erect setae. Head distinctly smaller than the prothorax, the eyes rather large, slightly longer than the tempora; antennas distinctly longer than the head and prothorax, stout toward apex, the tenth joint but slightly longer than wide. Prothorax slightly transverse, subglobular, finely, closely punctate, the horn well developed, two-thirds longer than wide, very feebly narrowed at base, not dentellate, the crest strongly developed and surrounded by a fine elevated and non-dentellate border. Elytra three-fourtlis wider than the prothorax, evidently less than twice as long as wide, feebly dilated behind; disk very minutely, evenly, moderately closely punctate; humeral Impression feeble; post-scutellar depres- sion distinct.

I¥. moil tail lis. — Stout, rather sliininf^, testaceous, the ahdomen darker; eh'tra dark piceous-hrown, ^vith a broad oven and parallel-sided transverse fas- cia of paler tint at basal third, and another, narrower, at apical third, the latter bent forward toward the suture; base and apex also paler; vestiture short, not very dense, somewhat coarse on the prothorax, intermingled with sparse erect sette on the elytra. Head much smaller tban the prothorax, pol- ished; eyes small, barely as lonu; as the tempora; antennaj two-fifths as long as the body, moderately incrassate, the tenth joint one-half longer than wide. Prothorax slightly wider than long, the sides oblique to the bjise behind the middle; surface finely, densely and rather rugosely punctate; horn well de- veloped, about one-third longer than wide, distinctly constricted at base, the sinuation broad, the border entire, the crest well developed, with its border strongly reflexed and entire.

Under surface densely pubescent, nnnutely, densely punctate, the legs slender. Length 2.9 mm.; width 1.0 mm. Colorado. This species, while allied in general appearance to some others of this group, ma^^ be distinguished by its stout form, and, from balteatus, by its smaller eyes, coarser punctuation and erect set;u of the el^^tra, these being completely wanting in that species. From bifasciatus it differs in its much longer and more distinct erect setfe, non-interrupted elytral fasci;v, dehiscent tips of the el3'tra, less incrassate antennfe and many other features. It is represented before me by the female only. IV. iilici'occi'llfii. — luither narrow, polished, dark rufo-piceous, the abdo- men black; elytra black, with a straight transverse and entire fascia just be- hind basiil fourth, and, on each, a transverse spot at apical fourth which is flexed obliciuely forward, liecoming feeble, to the suture; base slightly, the apex not appreciably, pale. Head but slightly smaller than the prothorax, polished, the eyes well developed; antennie long, slender, scarcely at all in- crassate, more than one-half as long as the body, dark rufo-testaceous through- out, the tenth joint about one-half longer than wide on the comjiressed side and nearlj' twice as long as wide alf rufo-testacoous throughout, the abdomen infuscate; elytra witli two small scutellar si)ots, a transverse fascia at apical two-lifths jirolonged along the suture Iieyond the middle, and a dark post-humeral marginal line, i)rolonged to the fascia or nearly to the apex, of black. Head as wide as the prothorax, minutely, densely punctate and dull, densely clothed with short appressed silvery pubescence; eyes large, longer than the tenipora; anteniuc moderate, feebly incrassate. Prothorax globular, Goleopterological Notices, VI. 76 Y the polished surface minutely, not densely punctate and not entirely con- cealed by the vestiture; Itasal tomentose line wide laterally but subobsolete in the middle; horn very broad and strongly developed, one-half as wide as the pronotal disk in the female, slightly narrower in the male, not constricted at base, rounded, finely dentellate, densely asperate, the crest moderately ele- vated and defined by a somewhat broken elevated margin laterally, not de- fined at the apex. Elytra about twice as long as wide in the male, rather shorter in the female, slightly wider at apical third and nearly twice as wide as the prothorax, rounded at aj)ex in both sexes; humeral impression very feeble, the scntellar obsolete; disk finely and closely punctate but not very dull, the pubescence dense, even, whitish and somewhat coarse; erect setaj abundant, moderate in length. Length :2.7 mm. ; width 0.8 mm. Texas (Galveston). This species is also allied to monodon, differing in its smaller size, narrower form, larger thoracic process, whiter pubescence, larger eyes and still more minute and much denser elytral punc- tures; the sides of the prothorax are more oblique anteriorly, the horn being much more gradually formed than in monodon. It is represented b^^ three specimens, in which the sexual characters are very feeble. jV. deserfllS. — Rather stout, slightly shining, iwle yellowish-testaceous throughout, the elytra with a small spot at each side of the suture near the base, and a transverse zig-zag fascia behind the middle, strongly produced an- teriorly along the suture beyond the middle, frequently subuniting by a feeble ray with each of the subbasal sjiots; sides behind the humeri faintly darkened. Head subequal in width to the prothorax, densely pubescent, minutely punc- tate, reticulate, somewhat dull, the eyes rather large, equal in length to the tempora; antennaj slender, slightly incrassate, fully two-fifths as long as the body. Prothorax rather small, globular, finely and sparsely ijunctate, shining through the somewhat dense vestitiire, the basal line dilated at the sides; horn well developed, differing somewhatuoticeably in the sexes; in the male smaller and narrower, more acuminate, not at all constricted at base and coarsely, deepljr dentellate, in the female larger and broader, feebly and finely dentel- late, broadly rounded and almost entire toward apex, feebly narrowed at base; crest abrujit, strong, limited throughout by a strongly elevated, acute and en- tire ridge. Elytra distinctly less than twice as long as wide, twice as wide as the prothorax, broadly rounded behind in both sexes, the sides parallel and almost evenly arcuate throughout; humeral impression very feeble, the seutellar wanting; disk densely, deeply and rather coarsely punctate, the de- cumbent pubescence coarse, whitish, moderately dense, the erect setai long, very abundant, coarse and conspicuous. Under surface densely pubescetit as usual. Length 2.7-3.5 mm.; width 1.0-1.15 mm. Arizona (Tu9son).

Head equal in width to the prothorax, narrower in the female, mi- nutely punctiite, reticulate, densely pubescent and dull; eyes large, longer than the tempora; antennie somewhat slender, moderate in length. Prothorax subglohular, slightly wider than long, the sides oblique and sinuate behind; disk rather coarsely, closely punctate, densely and coarsely pubescent; horn well developed, similar in the sexes, somewhat coarsely and deeply crenulate, broadly rounded and entire for a short distance at apex, Avidely dilated, strongly constricted at base, the crest broad, abruptly elevated, broadly rounded at apex and strongly delined throughout the sides and apex by an elevated black and entire ridge. Elytra a little less than twice as long as wide, dis- tinctly dilated at apical third and three-fourths wider than the prothorax, evenly rounded at apex, a little more broadly so in the male, the humeral im- pression very feeble; disk densely and rather coarselj^ punctate, densely clothed with coarse yellowish pubescence, the erect seta' somewh;it long, coarse, numerous and conspicuovis. Under surface densely and rather coarsely ])ubes- cent. Length 2.5-11") mm. ; width 0.95-1.2 mm. California (coast regions). The sexual differences at the posterior extremity' of the bod}^ are almost completely undeveloped, and exist only in the slightly more truncate elytra of the male. This species, which is repre- sented by a large series, has been heretofore almost universally confounded with the eastern monodoi), which it strikingly resem- bles in facies. It is however widely and constantl}"^ distinct in the form of the thoracic process, as ma}' be seen at a glance if the separated series be even casual!}' examined. The elytral mac. Illation is nearly as in vionodon, except that the subapical black cloud on each elytron, which is almost constantly present in that species, is here quite as constantly absent. In the vicinit}' of San Diego there is, however, a variety of consfrictus which has the lateral and subapical dark patches frequentl}' visible, and the thoracic punctures a little finer and sparser, agreeing rigorously with the northern forms in the structure of the thoracic process, except possibly that it is a little more pointed as a rule.

Length 5.0 mm. ; Avidth l.fJ mm. California (Lake and Los Angeles Cos.). This is the largest and stoutest species of the genus within our boundaries, and is somewhat similar in facies to some of the rel- atives of monodon, but is very distinct by reason of the truncate tips of the elytra in the male. The male type described above is from Lake Co., but the female before me from Los Angeles is similar throughout, except that the thoracic process is broadly dilated, rounded, and strongly constricted at base, and the elytra have, at each side just behind the humeri, an inwardly and pos- teriorly oblique dash of black. The male has the fifth ventral truncate at tip, with its surface broadly flattened near the trunca- ture. From serratus, to which it is allied more closely than any other described species, i^obusfus may be distinguished at a glance by its larger size and stouter form, more strongly constricted thoracic process of the female, longer and narrower crest, and in peculiarities of el^'tral ornamentation. In serratus the thoracic crest is very short. N. alainedae. — Stout, convex, rather shining, testaceous, the head darker, the elytra with a subsutural spot on each at basal fifth, and a trans- verse, very uneven and widely interrupted fascia at apical third, which is obliquely, more or less incompletely and indistinctly prolonged to the suture just before the middle, of black. Head scarcely in the male, very distinctly in the female, narrower than the prothorax, finely pubescent, the eyes moder- ate, prominent, not quite as long as the tempora; antenn;e long, slender, gradually and distinctly incrassate, fully two-fifths as long as the body.

Elytra twice as long as wide, rather less in the female, somewhat oval and convex, the sides parallel and feebly, equally arcuate, obtusely rounded behind, narrowly and obliquely truncate in the male; humeral impression feeble; punctures not coarse but strong, moderately distant; decumbent pubescence rather short, but somewhat coarse and close; erect settc long but line, sparse and inconspicuous. Length 2.9-3.4 mm.; width 1.0-1.4 mm. California (Alameda Co.). The peculiar oval convex form of the elytra, and departure from the usual t^'pe of ornamentation w'ill readil}' distinguish this species from serratus and robustus, to which it is somewhat re- lated. It is smaller than serratus^ with a much longer, narrower and more ill-defined thoracic crest and shorter, more oval and convex elytra. The female is much stouter than the male. It is represented by three si)eciraens. IV. pictiijii. — Narrow, elongate and parallel, rather dull, piceo-tcstaceous. black beneath, the legs and antennsc pale; elytra with the markings piceous the large scutellar spot frequently obsolete, the anterior fascia occasionally disintegrated into two large sublateral spots and an elongate and more pos- terior sutural area, the latter always joining the transverse post-median fascia; apices always i)ale.

The description refers to the male, and this sex has, in addi- tion, the fifth ventral sinuato-truncate in the middle at apex, the Goleopterological Notices, VI. TTl adjoining surface scarcely fit all raodified. The female difters somewhat, having the thoracic process slightly wider and just noticeabl3' narrowed at base, the elytra barely twice as long as wide and very broadly and obtusely rounded behind, and the elytral maculation paler and more suffused. In some of its characters pictus recalls sem'atus, the anterior fascia being a coalescent variation of the short dashes of that species, but the elongate, parallel elytra and non-dentellate thoracic process will always readily- distinguish it. It is difficult to understand how such a conspicuous form as this could so long have been over- looked ; it is represented in my cabinet by five individuals. MECYNOTARSUS Laf. The differences between this genus and Notoxus are very radi- cal, in spite of the general similarity of facies and possession of the pronotal process, which is so eminently characteristic of the latter ; in Mecynotarsus it is even more elaborately developed than in Notoxus. But in Mecynotarsus the tarsi are extremely long and filiform, with the penultimate joint cylindrical and un- modified. The body is always small and of elegant form, and the upper surface is devoid of the erect tactile setje so evident in Notoxus. Our species may be known by the following charac- ters, elegans differing almost subgenericallj^ from the fii'st three : — Upper surface clotlied with fine sericeous pubescence; eyes large; antennae very slender; thoracic horn finely and closely crenulate. Elytra devoid of median darker area. Atlantic Coast. Prothorax broadly rounded throughout at the sides, widest scarcely behind the middle; elytra very nearly twice as long as wide.

The fifth ventral of the male has a rounded and rather deep impression, which is larger and stronger than the homologous im- pression of candidus. Flavicans is a larger and evidently stouter species than candidus, and ma^^ be readily distinguished b}' the prominent sides of the prothorax. Xylophilin.e. The heterogeneous components of this subfamily, while bound to the Anthicinse by certain characteristics of facies, differ very radically in tarsal and abdominal structure, and also in the form of the labial palpi as indicated in the table previously given. The species are all small and generall}- quite minute, but the profound structural differences of the genera lends great interest to them from a morphological standpoint. The species of the various genera adhere closely in general appearance to the t^'pe form, and will prove to be rather numerous. They are, however, quite rare in cabinets at present, chiefly because no systematic methods have been pursued in collecting them, the onl}' exception to this known to me being the cabinet of Messrs. Hubbard and Schwarz, which contains good series of many species, carefully collected Coleopterological Notices^ VI. 7*73 in Florida, in Avhich region they seem to particularly abound. There are, however, also a large number of northern Atlantic species, but only a single one is known at present from the Pacific coast. A considerable number of Mexican species have been re- cently described by Mr. Champion. I have no hesitation whatever in separating our species into numerous genera, the generic characters being as pronounced as in almost any other group of Coleoptera, but as the types of Xylophilus, Euglenes and other of the older genera are unknown to me at present, I am forced to give them all distinct names, the probability being that none of them will prove entirely identical with any hitherto described.* These genera are the following : — Muzzle not prolonged before the point of antennalinsertlon 2 Muzzle prolonged; body very minute 11 2 — Head constricted at base; epistonial suture deep and distinct 3 Head not constricted at base 10 3 — Basal joint of the hind tarsi very long 4 Basal joint of the hind tarsi short, much shorter than the remainder 9 4 — Eyes deeply emarginate 5 Eyes feebly or moderately emarginate, the notch sometimes almost obsolete.. .6 5 — Head deeply sinuate at base; antennie thick and subcylindrical, the second joint obliquely truncate; vestiture short, matted and duplex. ..Eloiilis Head truncate at base; vestiture long, stift' and simple. Antennae inserted within the eye on the emarginating canthus, strongly flabellate in the male, not observed in the female Eiueliniis Antennse simple in both sexes, inserted just without the eyes, -which are generally not quite .so large Zoiiaiites 6 — Prothorax not prominent at the sides; eyes more or less coarsely faceted as usual 7 Prothorax angulate and prominent at the sides anteriorly 8 7 — Second and third antennal joints small PlloiiialllS Tliird antennal joint elongate. Prothorax as wide as the head; last antennal joint abruptly enlarged. Ariotiis * In general neatness of appearance, diversity of structure and individual rarity the Xylophilinse may be fancied to bear much the same general rela- tion to the other Anthicidaj that the Eucneminaj bear to the rest of the Elater- idse, and the Aveights of the two subfamilies, with regard to the remainder of their respective families, are about equal. The ratio of species to genera among our representatives of Xylophilinae is at present nearly 3, while among the Eucneminaj it is only about 2.5, and even in the Cerambycidaj it is not quite 3.5. The absolute value of the generic differences I hold to be about equal in the three cases. 774 Coleopterological Notices, VI. Prothorax narro^ver than the head.

In this genus the body is oblong, moderately convex, opaque, coarsely, densely sculptured and clothed with short confused pubescence intermixed with longer and more erect hairs. The head is deeply constricted and strongly sinuate at base, the fourth joint of the maxillary palpi moderately large and in the form of a right-angled triangle, and the last joint of the labial very large, slightl}' transverse, suboval, truncate at apex and deeply concave, with the surface minutel}^ granulose and sensi- tive beneath. The e3'es are large, deeply emarginate, coarsel}' faceted, conspicuously- pilose and distant from the base; antenuiie long, more or less thick, cylindrical and roughl}' sculptured, with the second joint transverse, short, as wide as the first but wider than the third and obliquely truncate at base, the last joint obliquely pointed or bent. The middle coxa; are well separated, the posterior subcontigu- ous, the basal process of the abdomen rather acute, the basal seg- ment of the latter having the dividing suture visible in the mid- dle very near the base and almost tangent to the acetabula. The posterior tibist are devoid of terminal spurs, but have instead a terminal tuft of yellow seta? externally ; the basal joint of the hind tarsi is extremely long, bent toward base and finel}' subcari- nate beneath. Goleopterological Notices, VI. Y75 The male sexual characters are extraordinaril}' developed, and affect principall}^ the entire surface of the abdomen and the pos- terior legs. The basal segment of the abdomen is impressed and more densely pubescent near each side of the body, apparently in both sexes. The pronotum is evenly convex, not at all im- pressed at any point, and is narrowed in front. The epistomal suture is very coarse and deep. The three species known to me ma}' be recognized as follows : — .Short pubescence of the eh'tra not forming a median fascia bnt more or less condensed along the suture. Front very densely punctate and granulose; epistoma densely pubescent; eyes separated by their own width; body large and stout. ..1. princeps Front sparsely punctate and with scattered minute, acutely elevated gran- ules; epistoma smooth, vdt\\ a few remote and feeble granules; eyes much more approximate on the vertex, separated by scarcely three-fourths of their own width; body smaller and naiTOwer 2. 1)asalis Short and pale pubescence forming a faint zigzag median fascia and an apical spot; last autennal joint elongate and bent, at least in the male; eyes still more narrowly separated 3. iiebulosus The elytral punctures in this genus are not only coarse but very deep, and their floors are flat and highly polished. 1. E. priiicep^ n. sp. — Oblong, convex, dull, brownish-black throughout, the tarsi, palpi and base of the elytra, more broadly at the sides, pale testa- ceous; pubescence short, moderatelj^ dense, the short hairs strongly condensed along the elytral suture. Head wider than long, thick, convex, very densely punctate and granulose, the antenna; thick, fully two-fifths as long as the body, gradually incrassate from the third joint, the joints feebly obconical, separated and perfoliate, transverse toward apex, the eleventh oblique and not quite as long as the preceding two together. Prothorax distinctly narrower than the head, a little wider than long; sides parallel and nearly straight in basal half, then strongly convergent to the arcuate apex, which is scarcely more than two-thirds as wide as the base, the latter very feebly arcuate; disk evenly, moderately convex, densely sculptured like the head, each puncture with an attached setiferous tubercle. Scutellum large, triangular, narrowly truncate at apex. Elytra two-thirds longer than wide, not quite twice as wide as the prothorax, parallel and nearly straight throughout at the sides, broadly but evenly rounded at apex, the humeri narrowly rounded, well exposed at base; disk feebly impressed at each side of the suture throughout the length, also feebly so within the humeri, the punctures very coarse, deep and dense. Ahflomen finely, moderately closely punctate, finely pubescent, the legs com- paratively short, not very stout. Length 3.0 mm.; width 1.25 mm. Canada (Ottawa). The type is a female, taken at the indicated locality by " W. 776 Goleopterological Notices, VI. H. H.", and very kindl_y given to me by Mr. Wiekham. It is one of the largest known species of the subfamily. 2. E. basalts Lee— Proc. Acad. Nat. Sci., Phila., 1855, p. 276 (Xjio- philiLS?). Color and sculpture as in the preceding, the basal pale space of the elytra large at the humeri, but only faintly extending across the scutellum, the latter more broadly truncate ; pubes- cence more narrowly and indistinctly- condensed along the el3'tral suture. Head transverse, the eyes at fully three-fourths of their own length from the base, and about as prominent as the tem- pora, the latter rounded ; antenntie nearly one-half as long as the body, the tenth joint transverse, the eleventh short, conoidal, much shorter than the two preceding. Prothorax much narrower than the head, fully as long as wide, otherwise as in princeps. Elytra nearly three-fourths longer than wide, fully twice as wide as the prothorax, feebly impressed along the suture, very coarsely, deeply and densely cribrate. Length 2.8 mm.; width 1.0 mm. Virginia and Illinois, — LeConte. This species is also represented in my cabinet by a single female, and is rather closely allied to jyrinceps, differing in its narrower form, more elongate and less robust antennjB, which are more rapidly and apicalh' incrassate, in its much less widely separated eyes, and other characters. In the male of both species the apical joint of the antennae is prob- ably much more elongate. 3. E. nebulosus Lee— Trans. Am. Ent. Soc., 1875, p. 175 (Xylophilus). Moderately stout, convex, opaque, black, the abdomen and elytra brown, the latter slightl}' paler at base ; tarsi and palpi pale ; pubescence moderatel}' dense, the longer hairs of the elytra moderate in length. Head transverse, the e^'es very large, more prominent than the tempora, distant from the base and separated by scared}- one-third of their own width ; antenna? three-fifths as long as the body, moderately stout, feebly incrassate toward apex, the eleventh joint long, cjdindrical, obtusely' and obliquely pointed, bent and distinctly longer than the two preceding, the tenth fully as long as wide. Prothorax aliout as long as wide, onl}- ver^' slightly narrower than the head, narrowed in apical half, the arcuate apex scarcely more than three-fifths as wide as the base. Elytra two-thirds longer tlian wide, twice as wide as the prothorax, parallel, obtusely rounded at apex, broadly, feebly Goleopterological Notices, VI. 77 T impressed along the suture toward base, rather strongly find more narrowl}' impressed within the humeri, the impression extending somewhat obliquely to near the middle of each elytron ; punc- tures verj' coarse, deep and close-set but not so dense as in iwin- ceps. Length 2.0-2.3 mm.; Avidth 0.8-1.0 mm. Pennsylvania. The two specimens before me are males, and I have not seen the female. The abdomen in the male is thrown up in a broad flat central region, involving the first three segments,, the elevation gradually becoming free, porrect and laminate- toward the apex, which is truncate, extending slightly over the- fourth segment, the latter being deeply and transversely exca- A^ated. The hind thighs are greatly dilated, clothed on the inner face with short and extremely dense brown pubescence, with a subbasal excavation which is more finely pubescent, the hind tibiae, and the intermediate to a less degree, arcuate, becom- ing slightly thicker toward tip. The corneous sheath of the in- tromittant organ is long, slender and veiy finely pointed. It is probable that the female has the e3'es less approximate and the terminal joint of the antenna shorter. There are few species of Coleoptera having more radical and remarkable sexual characters than this. The surface of the head and pronotum is densely opaque, the punctures being extremely deep and closel}^, polygonally crowded, not intermixed with tubercles, as they are in princeps and basalis. EMELI^US n. gen. The two species separated under this name have the eyes large, subbasal, emarginate through about two-thirds of their length, coarsely faceted, coarsely and sparsely pilose, with the antennm inserted on the canthus, the third joint of the latter much elon- gated and the succeeding joints flabellate in the male. The base of the head exhibits no sign of the deep median sinus of Elonus, and the sculpture and vestiture of the body are quite different. The epistomal suture is much less coarse, the terminal joint of the maxillary palpi nearly similar but the last joint of the labial is auriculate, transverse, pointed within, with the edges of the deep- ly concave lower surface pilose. The middle cox?e are more narrowly separated than in Elonus, and the dividing suture of the first abdominal segment is very strong throughout the width at some distance behind the coxtxi. The posterior tibiic are obliquely 778 Coleopterological Notices, VI. truncate at tip, with a few stiff terminal setx externally which scarcely have the nature of spurs ; the basal joint of the tarsi is ver}' long and slightly bent toward base. In the male the hind legs are much longer and proportionall}' a little stouter than the others, but there are apparentl}' no striking abdominal or crural sexual characters. The species may be known as follows : — Eyes separated by fully one-third of their own width 1. inelslieiiiieri Eyes extremely large, subcontiguous ; surface of the liead and pronotuni more opaque 2. a^liiueadi These species are each represented in my cabinet by a single male only. 1.

E. asliiiieadi n. sp. — Moderately slender and convex, dull, blackish beneath, the legs and abdomen paler; upper surface dark rufo-ferruginous, the elytra paler; pronotmn feebly nubilate with blackish, the elytra with three narrow blackish and uneven fasciie, the flanks also black except toward apex; Goleopterological Notices, VI. 779 autennse pale throughout, except the basal joint which is piceous-black ; vesti- ture moderate and subeven in length, subdecumbent, rather dense, very coarse and silvery in the pale elytral areas, finer and brownish in the darker spots and fascia?. Head transverse, the eyes occupying virtually the entire surface as seen vertically, except a triangular median area at base, which is very densely punctate and opaque; antennas three-fifths as long as the body. Pro- thorax much narrower than the head, scarcely as long as wide, the sides par- allel and straight in basal two-thirds, then strongly obli(iue to the rounded apex, which is scarcely three-fifths as wide as the base; disk not impressed, very densely, subtubercularly punctate and opaque, the pubescence very coarse and silvery in a large median area toward base and also at the sides. Elytra nearly as in melsheimeri, but much more densely punctate and duller, the blackish spots and zigzag fascia? much better defined; omoplates evident. Abdomen rather finely but strongly and somewhat densely punctate, the legs rather long. Length 2.1 mm. ; width 0.8 mm. Florida (St. Nicholas). Differs greatly from melsheimeri in its much larger ej^es, denser sculpture and more variegated pubescence. The antennae in both of these species become discontinuous in direction from the apex of the third joint, each joint after the third to the tenth bearing a very long slender pilose internal ramus, and gradually becoming longer and thinner in form, the eleventh very much longer, constituting by itself the outermost ramus of the flabel- lum. and having a remarkable knob-like enlargement near its apex which is much larger and more noticeable in ashmeadi. I have dedicated this interesting species to Mr. W. H. Ashmead of Washington, the well known student of parasitic Hymenoptera, to whom I am indebted for the unique t3'pe. ZOIVAIVTES n.'gen. This genus is rather closely allied to Emelinus, but differs in having the suture dividing the basal segment of the abdomen completely obsolete toward the middle and onl}^ feebly indicated at the sides, in the smaller and normal punctures, in the trans- versely parallelogramic prothorax which is subequal in width to the head, in the generally shorter, more oval and convex form of the bod}-^, and in the simple antennae of both sexes. The eyes are large, coarsely faceted, coarsely and sparsely pilose, deeply, sub- angularly emarginate and generally at a slight distance from the base, the tempora being much less prominent and rectangular. The epistomal suture is rather fine, the fourth joint of the maxil- 780 Coleopterological Notices, VI. laiy palpi somewhat more than right-angled, the terminal joint of the labial nearly as in Emelinus. The antennae are moderate in length, somewhat slender, with the third joint moderate in length, the eleventh swollen at the middle and very obliquel}^ pointed. Tibiae trnncate, with a slender setiforra internal spnr at apex. The eight species known thus far may be distinguished as fol- lows : — Elytra each with a submedian spot of black and another between basal third and fourth, the two generally united at the sides 1. iiullifer Elytra with a narrow dark median fascia widely interrupted at the suture, generally without trace of a scutellar spot; small species.

The elytral punctures, though generally rather coarse, are always simple and impressed, and do not have the flat polished floors ob- served in Emelinus. 1. Z. niibifer Lee— Proc. Am. Phil.

I am not at all sure of the generic position of this species, the above hastj^ notes having been taken from the unique type, which is now inaccessible. From an outline sketch made at the same time, the eyes appear to be much smaller than usual in this genus, and are at some distance from the base, and the prothorax is gradually narrowed behind from near the apex, which is also a character foreign to the other species, PHOMALUS n. gen. The small subequal second and third joints of the antenn.ne will readily distinguish the two members of this genus, and the fol- 786 Goleopterological Notices^ VI. lowing joints are somewhat stout, gradually and feebly incrassate, the eleventh rather small and obliquely obtuse.

Yestiture of the bod}' very short, decumbent, dense, consisting of very minute, and longer and sparser hairs, intermingled. This genus is quite distinct, and is the onl}- one which occurs in both the Atlantic and Pacific coast faunal regions. The species may be known thus : — Smaller and narrower, more opaque, the punctuation much denser; sides of the pvothorax not at all prominent behind the apex...l. brunnipennis Larger and n\ore obese, more shining, much less densely and less evenly punc- tate, the sides of the prothorax moreangulate anteriorly 2. saginattis The sexual characters are extremely feeble throughout. 1.

The fourth ventral of the male is dis- tinctly shorter than the third, broadly, evenl}^ rounded and un- modified, the genital segment small, coriaceous and rounded ; the fourth ventral of the female is fully as long as the third and is evenly rounded behind, without noticeable modification of struc- ture. 2. P. sagiiiatiis u. sp. — Stout, convex, feebly shining, pale brownish- testaceous, the abdomen piceous-black ; pronotum rufo-piceous; bead and hind femora blackish; pubescence ver}' short, moderately dense, decumbent. Head transverse, convex, somewhat closely punctate and conspicuously pubescent, the eyes separated by slightly less than their own width; antennnc stout, cylindriciil, scarcely at all incrassate, rather more than two-fifths as long as the body, the basal joint as long as the next two, jjenultimate joints as long as wide, the eleventh almost as long as the two preceding, obliiiuely pointed. Prothorax transverse, subeqiial in width to the head, the sides very feebly con- vergent from the subapical angles to the base; apex broadly arcuate, the base less arcuate; disk convex, finely, moderately closely punctate, broadly and extremely obsoletely impressed transversely near the base.

Length 1.8-2.1 mm. ; width 0.9 mm. California (near Montere}^). A specimen from Arizona is much smaller, witli narrower and more oblong el)'tra, which are more coarsely punctate and still more polished, the punctures more impressed ; it probably repre- sents a very closely allied species and is not included in the above measurements. This species differs conspicuously from brunnipennis in its more robust form, more shining surface, longer antennae and numerous other characters. Annals N. Y. Acad.

The body iu tliis genus is nariow, elongate and subparallel, the head not wider than the prothorax, with the epistoinal suture dis- tinct, the base transversely truncate and broadly arched, the eyes moderately large, rounded, subglobular, very coarsely faceted, scarcely at all setose and with only the slightest evidence of a minute emargination, the tempora very short, rounded and much less prominent. Last joint of the maxillary palpi short, very broad, the basal angle being very obtuse, of the labial moderately- large, transverse!}' subsecuriform, with the apex obliquely- beveled and sensitive, differing completely from the form seen in the pre- ceding genera. The antennje are rather short, slender, incrassate toward apex. The prothorax is transversel}^ and feebly obtrape- zoidal, not impressed, the scutellum small, narrowly trapezoidal, and the elytra parallel and devoid of distinct impressions. The middle coxae are narrowly separated, the posterior only slightly more widely so, the hind femora not dilated, the corresponding tibiae devoid of terminal spurs but with a porrect terminal plate internally, apparently composed of agglutinated setaj ; tarsi slightly shorter than the tibiae. The basal segment of the abdomen is not quite as long as the remainder, without trace of dividing suture, the second and third equal, and the fourth much longer than the third. Our two species differ decidedly and may be mutually dis- tinguished as follows : — Hc diflfers in having the e3'es slightly less finely faceted, the hind femur provided beneath with a dense comb of erect fulvous bristles almost throughout its entire extent, the humeri much less exposed, the antennrc filiform, and the pronotum C'oIeo2:>ferological Notices ^ VI. 801 devoid of the apical beaded edge ; the two species may, however, be considered congeneric for the present and can be distin- guished as follows : — Large, the elytra broad, linely and sparsely punctate toward base; color black, the prothorax dark red-brown 1. priliiio»>(ll$« Small and narro\\-, pale testaceous throughout, the elytra strongly and densely punctate toward base 2. liiteolus These species represent one of the most distinct generic types of the subfamily, because of the finely faceted eyes. 1.

Scutellum trapezoidal, wider than long, the angles somewhat prominent. Elytra broad, two-thirds longer than Avide, twice as wide ds the prothorax, parallel and feebly arcuate at the sides, broadly rounded at apex; humeri rounded, rather widely exposed at base; disk somewhat flat, the omoplates feeble ; punctures fine and sparse toward base, becoming gradually subobsolete behind the middle. Abdomen alutaceous, finely, densely pubescent, with a few small and scattered jiunctures in the middle near the base. Legs mode- rately long, slender. Length 2.8 mm. ; width 1.0 mm.

The sex of the unique individual is not determinable. 2. S. luteolus n. sp. — Narrow and somewhat convex, pale rufo-testa- ceous throughout, the elytra more flavate and the hind femora slightly brownish; integuments alutaceous, the minute punctules bearing the extremely fine decirmbeut pubescence not visible, being entirely occupied by the bases of the hairs; larger punctures rather dense and distinct.

The single type is a male, the intromittent organ being very slender, C3dindro-acurainate and three-fourths as long as the entire abdomen. The third ventral is obliquely truncate at the sides and is distinctly longer than the second, the fourth shorter than the third, broadly- bisinuate and feebly biimpressed along its anterior edge, the posterior edge broadly and very obtusely angu- late ; the genital segment is narrow and eniarginate. In both of these species the posterior margin of the pronotum has a small and feeble median sinus. CXOPl'S Champ.

GAlVASCrS n. gen. The complete lack of a basal cephalic constriction, which ren- ders this and the following two genera so aberrant, is somewhat suggested in Cnopus, where the constriction is carried forward, leaving the basal part of the head on a level with the pronotura.

Although this genus is one of the most distinct of the sub- family, the species which compose it are closely allied and will prove a difficult study ; the three which seem to be indicated by the material in my cabinet may be recognized as follows : — Elytral puncturas distinct and well separated, not concealed or obscured by the vestiture; elytra shorter and oval, the fuscous markings very much confused and scarcely at all definable.

The oval and convex form of body, indefin- able mottling of brown markings, and distinctly defined el3"tral punctures, will serve to identify this species, which is more north- ern in its range than the others. 2.

Readily distingnishaljle from the preceding by its smaller size, more shining surface, smaller head and prothorax, the latter more transA'^erse, sparser punctuation and, especially, by the an- tennal structure, the eleventh joint in venbncosiis not being abruptly wider than the preceding. The single specimen serving as the type is a male, and has a rather singular, abruptly pointed form of intromittent organ, which, as in other species of the sub- family, seems to be slightly asymmetric. 3.

This genus, while related to Ganascus, differs greatly in anten- ual structure, in its deeply emarginate eyes — the emargination, however, not being so deep as in the first three genera of the subfamily, — in its narrow and subcylindrical prothorax, and in general habitus. There is but one species, as follows : — 1. S. ptinoides Schz.— Proc. Am. Phil. Soc, XVII, 1S78, p. 371 (Xylo- philiis). Polished, black, the antenntB, palpi and legs pale flavo-tes- taceous, the intermediate femora slightly, the posterior deeply, blackish ; interspaces between the punctures not at all reticulate ; pubescence rather sparse and inconspicuous, except the coarser short white hairs, which are distinct on the head, in two narrow uneven pronotal vittse and at the sides toward base, and in a transverse uneven spot at basal fifth of each elytron, and another smaller and subsutural at apical two-fifths, these pubescent areas apparently rufescent. Head densely, coarsely and deeply punc- tate, the eyes separated by scarcel}' two-fifths of their own width ; antennae more than three-fourths as long as the body. Prothorax rather distinctly narrower than the head, slightly wider than long, parallel and feebly bisinuate at the sides, the apex and base equal ; disk strongly and densely punctate, feebly tumid along the middle toward base.

Body oval, convex, sparsel3' clothed with moderately short stiff and inclined hairs in a single uniform system. Head much narrower than the prothorax, against the anterior margin of which it is in close and even contact throughout, the surface forming also a low short laminate hood, which does not extend over the basal margin and which is continued narrowly behind the e^'es, expanded again beneath and before the latter, where its glossy concave surface is separated longitudinally from the extended front by a tumid and sparsely hairy piece, extending from the mandibles to the point of antennal insertion ; front broadly ex- tended before the antennte and as long as the entire basal part of the head. Epistomal suture coarse and very deep, the epistoma small, subquadrate, two-fifths as wide as the extended front. La- brum transverse, feebly convex, translucent, broadly' bilobed at apex.

It is almost impossible to describe the remarkable double snr- foce at the posterior margin of the head in an intelligible manner, and, in view of this very aberrant structure, as well as the abnor- mal anterior parts of the head and the broad base of the pro- thorax, we must regard Axylophilus as the most specialized and extraordinary type of the entire subfamily ; it is also the most minute representative Avithin our faunal limits. The antemiie are very similar in form to those of Trichopteryx. 1.

This exceedingly interesting species was taken al)undantly by Messrs. Hubbard and Schwarz, on plants of the genus Yucca. OTIORHYNCHID.E. The known forms allied to Dyslobus have become very nume- rous by reason of recent collecting on the west coast, where they constitute the most conspicuous and abundant otiorhynchide ele- ment of the true Pacific coast fauna; they are especially nume- rous and diversified in northern California and in Oregon. The larger and more striking of these species, which I have set apart for investigation at the present time may be assigned to four o;enera as follows : — 810 Goleopterological Notices, VI. First ventral sutiue very deep ami widely inijuessed, generallj' straight or only sliglitly arcuate in the middle; second segment not longer than the next two com])ined; met-ejiisternal suture distinct; scutellum very sliort and ))road, not entering the elytral disk. Elytral intervals not alternating in convexity Dyslobus Elytral intervals distinctly alternating in convexity throughout the length. Aiuiiesia First suture fine, not broadly impressed and broadly arcuate. Body squamose and pubescent; scutellum distinct; second ventral segment mudi longer than the next two combined; met-episternal suture distinct. Adaleres Body scjuamose, the elytra without erect hairs, the intervals alternating strongly in convexity and vestiture; scutellum extremely small, acute; second ventral segment not longer than the next two combined; niet- episternal suture completely obliterated IVomidus In this sclierne Amnesia is limited to tliose speeiee having the elytral intervals strongly- alternating in prominence, and it is probable that other genera will ultimately have to be formed for the smaller and more obscure species, such as rauca and decorata, at present associated with them ; it is more than probable that these forms can be included in Lepesoma of Motschulsky, although L. californica can never be identified without the type. I can find no essential difference in the form of the first ventral suture and relative extent of the second segment, which were advanced by Dr. Horn to distinguish Dyslobus from Amnesia (jranicoJIis, the type of Amnesia, and the dilferential character which that author attempts to draw from the internal terminal spur of the hind tibije is wholl}' illusory and devoid of value in tliis particular connection. These four genera are in fact intimately allied among them- selves, having the beak rather elongate, separated from the head by a transverse depression and with the scrobes short, Hexed gradually downward, broadening and becoming evanescent far before the e^^es, and the ocular lobes at least moderately distinct throughout. In the table given by Dr. Horn (Proc. Am. Phil. Soc, XA'', p. 38), Dyslobus and Amnesia are widely separated b^'^ a number of genera which are not particularly closely related to them, and in some cases widely dissimilar in important details of structure.

The species of this genus are rather large and elongate, some- what less so in the female than in the male, and have the ocular Goleopterolorjical Notices^ VI. 811 lobes much broader and shorter than in Amnesia, the eyes being invariably far distant from the prothorax. The three species ma}' be distinguished as follows : — Elytra! siiture prominent and keeled near the summit of the posterior declivity ; serial punctures each with a rather large scale hut otherwise nude. Serial punctui'es small; hind tibiiic ver^^ strongly bent near the apex in the male segiiis Serial punctures much coarser ; scales brilliantly metallic in color ; hind tibite of the male only very feebly arcuate toward apex lecoiitei Elytral suture not keeled near the apex but with a small and abruptly ele- vated double tubercle; serial punctures not squamigerous but each with a short hair attached anteriorly; scales in great part opalescent. .verriicifer D. segnis of LeConte (Pac.

AJttSfESIA Horn. This genus is very closely allied to Dyslobus, but may be dis- tinguished not only by the alternately convex elytral intervals, but by the greater prominence of the ocular lobes ; there is con- siderable variation in the latter character, however, as is gener- ally the case within generic limits, and the lobe is very much shorter and less distinct in scnlptilis than in tumida. The species known to me may be thus outlined : — Elytra siiarsely but strongly tuberculose throughout, the sutural prominence . at the summit of the apical declivity very pronounced tlliuida Elytra not tuberculose, the sutural prominence moderate or feel)le.

Coleopterological Notices, VI. 821 As the supports of the deciduous pieces of the mandibles are very prominent, I am disposed to place this genus near Diamimus. It however differs greatl>' in having no vestige of a transverse depression separating the head from the beak. M. scapalis n. sp. — Narrowlj' ovoidal, black, the antennaj and tarsi not paler; bodj' densely clothed above and beneath with rather small, oval, slightly overlapping and strongly strigose scales, which are pale brownish in color but becoming indefinitely whitish along the flanks and beneath, and very feebly variegated with a slightly paler tint at the base and near the apical declivity of the elytra, the scales intermingled throughout with numeroiis short, stout, erect and brownish hairs which are unevenly arranged on the elytra. Head scarcely one-half as wide as the prothorax, the eyes prominent and separated by two and one-half times their own width; beak short and broad, one-fourth longer than wide, two-thirds as long as the protliorax and distinctly longer than the head, broadly impressed along the middle toward apex but not cari- nate or otherwise modified; antennal scape densely clothed with narrow whitish scales and bristling with sparse erect setae, the funicle equally bristling and also clothed denselj^ with short stout appressed whitish hairs, the club equally densely clothed with stout brown hairs and with a few short erect setae.

The sex of tlie single type specimen is not determinable at present. The posterior declivity of the elytra is rather deep and nearly straight and vertical in profile, but the summit is not prominent and joins the general outline of the upper surface by a broadly rounded arc.

Length 10.0-11.3 nnn. ; width 4.4-4.8 mm. New Hampshire. Distinguishnble from canadensis by its move elongate form^ much more gradually and feebly declivous apical parts of the elytra, more obtuse rostral carina and more fineh' and less rugosely sculptured elytra. The two specimens before me are almost completely denuded throughout, so that it is impossible to describe the vestiture. Li. canadensis n. sp. — Stout, suboval, stnmgly convex, black, the ru- gosities polished; vestiture consisting of moderately dense slender scales, pale brownish in color, variegated with nubilate patches of white toward the sides of the elytra, with a white spot before the middle of each, the narrower inter- vals principally clothed with brown scales; oblique vitta; of the prothorax narrow and white.

Length 11.0 mm. ; width 5.0 mm. Canada (northwest). Quite distinct from geminatus by the sculpture of the elj^tra, and from alternans by the equal rugosity of the elytral inter- vals. The el^'tra are rapidly declivous behind in profile. Li. piiigilis n. sp. — Obese, black and polished when denuded, densely clothed with narrow pale brown scales intermixed with still narrower white scales, and variegated on the elytra with small condensed spots of the brown scales situated between the serial punctures; oblique sublatei-al vittiE of the pronotum broad, yellow and uneven; elytra each with a more conspicuous ochreous spot before the middle; abdomen with the sublateral yellowish spots small.

Length 9.0-10.2 mm.; width 3.9-4.5 mm. Wisconsin (Bayfield, — Mr. Wickham) and Missouri. This spe- cies has heretofore been confounded with the European palusb'is Scop., which it somewhat resembles. It differs however from pa- lustris, as represented by the numerous European examples be- fore rae, in its more elongate form, much larger and more trans- verse prothorax carinate along the middle, in its carinate beak and much sparser vestiture. In the European species the beak is still more slender, more cylindrical and is generally wholly devoid of carina, though having occasionally a feeble trace, and the pronotum is not carinate as it is in geminatuH.

Head about one-half as wide as the pro- thorax, densely squamulose, the scales of the beak longer, whiter and hair-like; interocular fovea deep, narrow and fusiform ; eyes rather convex, separated by somewhat less than twice their own width ; beak long and somewhat stout, longer than the prothorax, straight but bent downward from the point of an- tennal insertion, the surface roughly punctato-rugose, the carina feeble and subobsolete near the base; antennis long, the second funicular joint much longer than the first, the seventh transverse. Prothorax only slightly wider than long, the sides subparallel, sometimes slightly convergent toward base, rough and uneven, constricted behind the apex, the latter broad, truncate and tubulate; disk rugose, the median carina narrow and strong, disappearing in the median impression at the base. Elytra more than one-half longer than wide, generally not quite twice as wide as the prothorax, the sides parallel and broadly rounded, the apex triangular with feebly arcuate sides which are discontinuous with the sides from the umbones to the base, the sutural angles individually augulate and separated by a pronounced notch; disk gradually rounded and decli\ ous behind in profile, the tips explanate, the surface uni- formly and finely rugose, the series alternately perceptibly more approximate; serial punctures differing greatly in size and generally widely spaced, the larger very elongate, deep, coarse and perforate.

It may be placed near rotu7iclicoUis in the arrangement recentl}^ proposed by LeConte (Proc. Am. Phil. Soc, XY, p. 128.) PLECTROMODES n. gen. (Phytonomini). Body oval, very convex and sparsely pubescent, the elytra acutely prominent at the sides behind the humeri. Head sub- globular, moderately inserted, the eyes scarcely convex, trans- verse, distant from the base, somewhat coarsely faceted, mode- rately separated above, remotely so beneath, truncate anteriorly, graduall}^ obtusely pointed beneath. Beak short, thick, cylindri- cal, feebly dilated toward apex, the scrobes extending almost to the tip, becoming partially visible from above, obliquely descend- ing toward base and terminating at the lower angle of the eye.

Mentum trapezoidal, rather longer than wide, not concealing the maxillary cardo ; gular peduncle long, narrowed at base. Prothorax without ocular lobes. Anterior coxae large, prominent, contiguous, the prosternum before them short, sinuate and unimpressed ; middle coxre narrowl}' sep- arated, the posterior also api)arently rather approximate. Abdo- men flat, the two basal segments each as long as the third and fourth together, the dividing suture moderately coarse and broadl}' angulate ; fifth rounded and nearl3' as long as the two preceding together,; posterior sutures coarse and straight.

This singular genus is assigned to the Phytonomini onl}- pro- visionally and for convenience, for it probably represents a distinct though closely allied tribe. The peculiar dentiform prominence at the sides of the elytra behind the base is suggested in a species of Listronotus, described above in order to bring out this chai'acter, and the beak with its scrobes and the formation of the prosternum are all strongl^^ suggestive of that genus. The two species before me may be distinguished as follows : — Body stout, the elytra with two apical areas of dense pubescence, the promi- nences at the summit of the declivity also densely pubescent. paliidatiis Body uiuch smaller and less robust, the elytra without the a])ioal pubescent areas, the prominences at the summit of the declivity not pronounced and scarcely more densely pubescent a riiiatus The genus Plectromodes is probably confined to the United States east of the Kocky Mountains, extending into the northern parts of the Sonoran province, but not forming an element of the tropical Mexican fauna. P. paliidatiis n. sp. — Broadly oval, strongly convex, black and polished throughout; pubescence consisting of sparse suberect white hairs, moderate in GoIeo2)terological Noticef<, VT. 831 length, distinct and abundant on the pronotum, very sparse on the elytra but denser in a transverse region near basal third, much longer near the sides, in two sjwts near apical third and in two apical areas.

Ryssematus in sp. Elytra unicolorims throughout and generally black, subglahrous or with the minute hairs only moderately conspicuous and evenly distributed. Elytral carinas more strongly developed; species larger. Prothorax slightly inflated behind, the sides becoming parallel toward base. Elj'tra dull, the serial punctures narrow, elongate and widely spaced, becoming linear and verj^ feeble toward apex, tlieoarin;e only mod- erately elevated gl'iiiiclicollis n. sp. Elytra rather shining, the serial i)iinctures coarse and somewhat close- set, distinct to the apex, the carin;e very strongly elevated. liiieaticollis Say Prothorax not inflated, the sides divergent to the base and never parallel; pronotal rugne coarse and converging jiosteriorlj' toward the middle; body much smaller and narrower, the prothorax relatively smaller and more conical aiiiiecleiis n. sp. Elytral carinie very feeble, the Hat intervals rugose; pronotal riigix; coarse and strongly obliiiue; miiuite hairs of the elytra (juite numerous and dis- tinct; small species aeqiialis Horn Elytra pale or mottled, always distinctly pubescent. Coleopterological Notices, VI. 833 Elytra in great part blackish, Avitli small feeble riifescent markings to ■which the unevenly distributed pubescence is principally confined. Intermediate intervals of the elytra not at all carinate; pronotal rugae long and oblique palinacollis Say Intermediate intervals feebly and incomj)letely carinate; pronotal rugae less oblique luedialis n. sp. Elytra in great part pale, the pubescence longer, more evenly distributed and very conspicuous; pronotal rugic oblique pubescent Horn Alternate intervals not at all carinate. Sermysatus n. sg. Eyes rather narrowlj^ separated on the front prtliiioiiilis Boh. Eyes widely separated, the beak less elongate and less slender. Body rather broadly oval, the abdomen distinctly punctate ovalis Csy. Body narrowly oval and much smaller, paler in color, the abdomen only slightly punctate pai'Viiliis n. sp. In the United States the genus Ryssematus is confined to the eastern faunal regions, extending into the Sonoran province. No species is known to occur within the true Pacific coast region. R. graiidicollis. — Broadly oval and very convex, deep black through- oirt, the antennte and tarsi only slightly piceous; setaj along the elytral ridges very minute and Inconspicuous. Head scarcely one-third as wide as the pro- thorax, deeply, densely punctate and with short fulvous hairs, the eyes large, broadly sinuato-truncate anteriorly and margined with a deep groove behind, rather narrowly separated on the front; beak thick, as long as the head and prothorax, feebly arcuate, slightly thinner and somewhat bent near the apex, strongly carinate abovefrom the interocular fovea to the anteuute, finely, rather sparsely punctate toward apex, longitudinally riigose, dull and more densely punctate thence to the base especially at the sides; an tenuic inserted just be- yond the middle, the basal joint of the funicle about as long as the next two. Prothorax large, about twice as wide as long, strongly rounded at the sides, the latter becoming parallel and arcuate in about basal third, strongly convergent anteriorly ; apex arcuate and distinctly less than one-half as wide as the base, the latter transverse; disk closely, longitudinally rugose, the rugae much'disintegrated at the sides and on the flanks beneath, becoming much confused, more feeble and somewhat dull, the feeble "apical constriction more coarsely and deeply sculptured as usual. Elt/tra distinctly longer than wide, only very slightly wider tlian the prothorax, the sides slightly convergent and feebly arcuate from the large and moderately prominent humeral protuberances to the apex, the latter somewhat narrowly rounded; disk very dull, the obtuse crests of the feebly elevated carinaj alone polished ; punctures rather shallow, elongate and distant, connected by fine, scarcely impressed but more shining lines and becoming very small toward apex. Abdomen coarsely punctate at base, thence finely, rather densely so to the fifth segment, which is very 834 Goleopterological Notices, VI. densely and somewhat finely punctate, the legs stout witli the femoral tooth large. Length G.7 mm.; width 3.7 mm. Iowa (Keokuk). Readily distinguishable from lineaticollis by its stouter form, still larger and more inflated protborax -which is much more feebly and indefinitely rugose at the sides beneath, and by the peculiar feeble elytral sculpture. The single type before me is apparently a male, but the fifth ventral is scarcely perceptibly modified on the disk. R. a nnectens.— Narrowly oval, somewhat shining, black, the tarsi antl antennic rufous, the clul) of the latter infuscate; minute elytral setic entirely inconspicuous. Ilmd rather more than one-third as wide as the prothorax, somewhat finely and densely punctate, f\ilvo-pubescent; eyes narrowly sepa- rated on the front, broadly sinuato-truncate anteriorly; beak almost as long as the head and prothorax, nearly straight, feebly and obliquely flattened distally, finely and sparsely punctate toward apex, thence more obviously sculptured and punctate in longitudinal eroded ruga; to the base; dorsal carina mode- rately developed, the interocular fovea small; antennae inserted quite distinct!}' beyond the middle. Prothorax small, nearly twice as wide as long, feebly constricted at the apex, tiie latter one-half as wide as the base; sides strongly, evenly convergent and feebly arcuate from base to apex; disk coarsely plicato- rugose, the rug;e sinuous and quite uneven, inwardly and posteriorly oblique toward the middle, moderately disintegrated and with the lustre duller on the flanks beneath. Elytra distinctlj' longer than wide, nearly cme-third wider than the prothorax and about three times as long; outline oval, the humeral convexities feeble; carinie moderately strong, the intervals alutaceous and nearly smooth, the serial punctures deep, somewhat elongato-subquadrate and separated by about their own lengths, distinct to the apex. Abdomen very densely punctate throughout, more coarsely so at base. Length 4.8-5.0 mm.; width 2.6 mm. Indiana ? Two specimens from the Levette cabinet without labels, but probably taken in or near the above region. This species cannot be confounded with any otlier, for, with a general facies sugges- tive of lineaticollis, it has the oblique pronotal rugic of pahna- collis and some other pubescent species. The prothorax is very much smaller than in any other species of the lineaticollis group of the genus. The types are probably- males. R. medial is. — Subrhomboid-oval, strongly convex, rather shining, dark rufo-piceous, the legs and upper surface somewhat darker, the elytra with small indefinite paler areas especially toward apex; pubescence sparse, evenly distributed and consisting of short erect yellowish setai on the prothorax, on Goleopterological Notices, VI. 835 the elytra iineven and denser on the small pale areas. Head more than one- third as wide as the prothorax, coarsely, densely sculptured, not very densely f ulvo-pubescent ; eyes large, very coarsely faceted and almost contiguous on the front; beak rather long and slender, feebly arcuate, nearly one-half as long as the body, cylindrical, shining and finely, distinctly punctate toward apex, dull, longitudinally and feebly rugose and not distinctly punctate to- ward base, the dorsal carina almost obsolete except toward base; antennse in- serted distinctly behind tlie middle, the basal joint of the funicle as long as the next two. Prothorax small, rapidly conical, nearly' twice as wide as long, the sides strongly convergent from the base and only just visibly arcuate; disk with fine, strongly elevated and anastomosing rugse, which are rather widely distant and inwardly oblique posteriorly, the median carina fine and distinct, the rugfe feebler, closer and less defined on the flanks beneath. Elytra from above one-fourth longer than wide, one-fourth wider than the prothorax and not quite three times as long, the carinaj rather broad and moderately elevated, the intermediate intervals also obsoletely carinate, the serial punctures mod- erately coarse and close-set, slightly elongate and distinct to the apex. Ahdo- men shining, feebly and not very closely punctate, rather densely so however on the fifth segment; metasternum coarsely but somewhat sparsely iiunctured; legs moderate, the femoral tooth well developed. Length 4.2 mm.; width 2.3 mm. Arizona rTu9son). Mr. Wickham. This is a distinct species, readil}' distinguishable from any other by the subcarinate intermediate intervals of the elytra ; the eyes are even more approximate than in the lineaticoUis group. There are before me two specimens which I refer to pubescens Horn ; one of them is from an unknown part of Arizona, and the other from San Augustine, New Mexico, collected by Mr. Cock- erell ; there are some slight differences between them but both satisfy the description sufficiently well ; the alternate elytral in- tervals are flat, and the eyes are less approximate than in nie- dialis. R. parvulus. — Narrowly oval, very convex, strongly shining, pale rufo- testaceous throughout, glabrous. Head nearly two-fifths as wide as the pro- thorax, rather sparsely punctured; eyes in considerable part covered by the ocular lobes in repose, widely separated on the front, the interocular fovea dis- tinct; beak rather slender, cylindrical, evenly and feebly arcuate, longer than the head and prothorax, shining, finely but distinctly, sparsely punctate, not at all carinate above toward base; antennae slender, inserted at about the mid- dle, the basal joint of the funicle elongate as usual, club long and narrow, pointed. Prothorax fully three-fourths wider than long, feebly constricted near the apex, the latter nearly one-half as wide as the base; sides strongly convergent and broadly, evenly arcuate from the base;
