BY THOS. L. CASEY. Read October 5, 1891. The most important contribution presented in the following paper, at least from a systematic standpoint, is a review of the CistelidjB of the United States, but I feel only too fully that the discussion of the species of a local fauna, however complete and well intended it may be, can count but scarcely more than as a letter in the alpha- bet of a general monograph. In the absence of representatives from other parts of the earth, we labor to a great extent blindly in the delimitation of the higher groups, and in selecting proper structural characters for the differentiation of the genera. For various reasons, however, the accumulation of the necessary material for a general revision of any family of Coleoptera, i^ now an exceedingly difficult matter, and this difficulty is, with the present system of museum management throughout the world, a constantly increasing one. Whether or not we are to have any more epoch- making inonographs, is becoming largely a question for the museums to decide, for it is here that material is principally accumulating. These reflections call to mind another feature of the case, in which this restrictive policy of the museums is to a great degree embar- rassing, and which concerns us on this side of the Atlantic more particularly — I refer to the American types of Mannerheim, Maklin, Eschscholtz, and Motschulsky. These are now reposing in extreme security within some almost inaccessible European museums, where- they are practically never disturbed, but if transferred to an Ameri- can museum where they could at least be occasionally examined by our working entomologists, it would be a vast aid to us and would be a loss scarcely at all appreciable to them. I go so far as to say that all satisfactory study on our part in certain directions is com- pletely checked, because of the absence of these types ; from an Annals N. Y. Acad. Sci., VI, Nov. 1891.— 2 10 Coleopterolocjical Notices, III. equitable and reasonably liberal point of view they should be placed in our keeping, for the descriptions to which they answer are in general quite insufficient, and are often worse than useless from inaccuracy of statement. After this short and I trust pardonable digression, it only remains to be said, that the present opportunity has been taken to publish the descriptions of some other more or less interesting species, mainly in the Longicornia and Heteromera. New York, August 18, 1891. Note. In a report of the proceedings of the Second Ornithological Congress (Nature, No. 1129, p. 153), it is stated that among other resolutions favorably passed lupon was the "adoption of names, even faulty in construction or misspelt, "with all the consequences." The phrase "ivith all the consequences^^ affords a convenient pretext for the further discussion of certain matters concerning nomenclature, which I have previously touclied upon to some extent. The designation of every species consists of two distinct parts : the generic symbol and the specific name. The former need not necessarily have any meaning whatever, the latter always must have a meaning ; we should there- fore ajiply to these two parts rules which are somewhat different. I apply the word " symbol" to the generic designation, because the latter is not a word in the ordinary sense of being a combination of letters possessing linguistic meaning, but is simply a coordination of letters, the sole conditions of which are that of being readily pronounceable, or consisting of consonants and vowels harmoniously arranged, and of having a Latin termination, in order to determine generic endings in the specific name. Even this last condition has not been strictly oomiilied with, as a great many generic symbols have Greek or barbarian terminations, often necessitating the arbitrary determina- tion of gender; nevertheless, words with endings which are neither Latin nor Greek, such as Marail Less, and Lemming Cuv., should not be admitted. The earliest printed symbol satisfying these conditions should be the one adopted. The specific designation is, however, a word taken from the Latin, or from any other language through the Latin by universal agreement, in order to avoid the undue favoring of any of the languages at present in use, and the inevitable discordances of opinion which would result therefrom. As one of the prime conditions of the specific name is that it shall have a meaning, and must therefore be linguistic in form and origin, there can be no objection to the alteration of the printed word to suit the proper rules of orthography or gender, when the intentions of the imposer of tlie name are evident. There are, in fact, on the ground of uniformity and simplicity, many reasons why this should be done, and why rules should be laid down and followed for writing specific names derived from various sources. Coleopterological Notices, III. 1 1 Now let us ask the question : Upon what foundation principle does the permanence and inflexibility of our nomenclature depend ? — for no scientific notation or symbol ization in any branch of human investigation can be of value, which is not put beyond the power of individual opinion to alter at pleasure. This question seems to be easily answerable if (1) we agree to adopt the earliest properly published combination of letters intended to represent any particular genus, and (2) if we formulate invariable rules for writing specific names, but is apparently unanswerable under any other conditions. If a writer be permitted to alter the original spelling of a generic symbol on the ground of incorrect orthography, we at once dispel any hope of permanence in nomenclature, and open the door to new argument and discussion which may result in a subsequent author giving a third designation, based upon his own conception of the hypothetical intentions of the original namer, and so on without end to the ultimate destruction of all semblance of stability : for there are differences of opinion as to the proper spelling of certain words in all languages. If it be asked why the generic symbol need have no meaning in any lan- guage which has ever existed, while the specific designation is required to have a meaning in or through the Latin, it may be answered that it simply results from the condition of nomenclature as we find it to-day. One need but glance over a small portion of the great Munich Catalogue, to see that the proportion of generic words of unknown or dubious etymology, is so great as to give character to the whole, and to necessitate the rule that generic words must simply be considered harmonious combinations. In regard to the specific names, however, we can perceive at once that the proportion of words among them which are devoid of meaning or withdrawn from the influence of linguistic rules, is not large enough to have any weight at all. In view of these facts, it is quite incomprehensible how the original generic symbols Breutus, Sitona, Monochamus, Leiopus, Leichenum and a host of others, could have been changed as they have been. Are not the words noted harmonious combinations, and, as such, are they not as much entitled to stand as Brenthus, Sitones, Monohammus, Liopus, and Lichenum ? We must go back to the original mode of spelling generic names before nomenclature can be placed upon an absolutely stable foundation. The next catalogue similar in scope to the Munich Catalogue, will be the first suitable opportunity for efl'ecting this change, and it is hoped that the liberties in spelling which have been proposed in the one alluded to, and which constitute its only serious blemish, will not be repeated. Other questions involving more or less difi'erence of opinion occasionally arise, as for instance whether generic names, diflfering only in termination by reason of gender or derivation, as for example Oplocephala and Oplocephalus, Platycerus and Platyceras, or Tylas and Tylos, should be maintained as dis- tinct. As the words become shorter such difi'erences of ending constitute a great part of the entire symbol. Ulus, for example, is quite a difi'erent word from Ula, Ixus from Ixa, Janus from Jana, and numeroiis such resemblances exist at present, but if we admit that Ulus and Ula are satisfactory as generic 12 Coleopterological Notices, III. symbols, and thei'e cau be but little doubt that they are, we must also admit Oplocephala and Oplocephahis ; we should have absolute and consistent law throughout. I believe the difficulty can be overcome if we hold tliat generic symbols are not words in any sense, but constants, analogous to the constants of a mathematical formula ; that they form part of no language, — although Latin by induction, and that they are completely indeclinable, except when used in the genitive as specific names or in the nominative plural as group names. Under these circumstances Ulus and Ula would be distinct and different combinations of letters, and could be maintained as genera with perfect propriety. The Ornithological Congress has passed favorably upon the trinomial nomen- clature. In j-egard to this it need only be said that the admission is a dan- gerous one, for it will result finally in names including four, five or even six words, and nomenclature will gradually become involved in a web of its own weaving. If the trinomial nomenclature is admitted, it should only be with the understanding that either the specific or siibspecific name be bracketed. Our system should remain essentially binomial. CUCUJID.E. LYCTIJS Fab. The characters given by me (Ann. N. Y. Acad. Sci., Y, p. 324), to distinguish the two genera Lyctus and Trogoxylon, I find to be of no value, for, while applicable to the latter as represented by paraUelopipedus, the distance separating the anterior coxip gradu- ally diminishes through calif ornic as and puncfatiis to the slight prosternal width characterizing cavicollis and others. So also in regard to the external prominence of the anterior tibiae at apex, not at all discernable in cxirtulus and a little more pronounced in paral- lelopipedus, it becomes normally prominent in punctatus, this char- acter not having the value here which it has in Eurymetopon. The elytral punctures are completely devoid of serial arrangement in parallelojnped us, have a slight tendency thereto in punctatus, and are distinctly seriate in californicus. There are the same grada- tions in regard to the prominence of the apical angles of the pro- thorax. I am forced therefore to regard Trogoxylon as a synonym of Lyctus, and, a few new forms having been recently received, the present opportunity is taken to give a complete statement of our species as far as known : — Coleopierological Notices, III. 13 Elyti-a with series of large rounded shallow punctures, the intervals each with a single series of small coarsely setigerous punctures striatlis Elytra without series of large shallow punctures, the punctuation however having a more or less distinct serial arrangement. Apical angles of the prothorax rounded. Prothorax longer than wide, not or extremely feebly and narrowly im- pressed ; body ferruginous opRCtllUS Prothorax quadrate. Ferruginous ; pronotum broadly, rather strongly impressed. cavicollis Black ; i^ronotum more shining, more sparsely jiunctate, less convex and less impressed along the middle planicollis Prothorax much wider than long, nearly as wide as the elytra ; l>ody black ltai*TlllllS Apical angles of the prothorax not rounded. Larger species; eyes large; elytral series well marked cai'Oliiiae Small species ; eyes small ; elytral series more feebly defined. californiciis Elytra with the punctures denser, confusedly arranged or without distinct serial arrangement; apical angles of the protliorax not rounded. Prothorax as long as wide or extremely nearly so ; anterior coxae widely separated. Anterior tibiae gradually much broader from base to apex, not everted externally ; basal angles of the prothorax narrowly rounded. ciirtiilits Anterior tibiae slender, gradually but slightly broader, and finely, exter- nally everted at apex ; basal angles of the j^rothorax not rounded. parallelopipediis Prothorax much wider than long pilllCtattls In the genus Lyctiis the slight serricorn affinity indicated perhaps through some extinct or undiscovered genus allied to Psoa, is par- allel to the melyride affinity of Berginus, as shown by its general habitus, and means nothing more, the two affinities being about equally pronounced. Li. caroliliaB n. sp. — Parallel, moderately slender, rather convex, ferru- ginous, the head and prothorax darker than the elytra ; integuments shining, the vestiture rather inconspicuous, yellowish. Head rather coarsely, moder- ately densely punctate ; antennae slender, one-half longer than the head, the club moderate, joints three to five subequal, nearly twice as long as wide. Prothorax about as long as wide, the apex distinctly wider than the base, evenly, strongly arcuate throughout ; base broadly but less strongly arcuate ; sides feebly convergent from the apical to the basal angles and just visibly sinuate throughout ; apical angles feebly, laterally prominent, right, very slightly blunt but not rounded; basal angles slightly obtuse but not at all 14 Coleopferological Notices, III. rounded ; disk feeblv convex, broadly, distinctly impressed along the middle, rather coarsely, deeply and densely punctate, the interspaces narrow but polished ; pubescence short and rather sparse. Elytra about three times as long as the prothorax and but just visibly wider than the latter, about two and one-third times as long as wide, parallel, the sides straight, very abruptly and obtusely rounded behind, the humeri right, narrowly rounded and rather broadly exposed ; disk cylindrically convex, the punctiires rather fine but deep, slightly oval, iinevenly aggregated in narrow distinct series, but con- fusedly arranged near the suture, more broadly so toward base, the intervals between the series minutely, confusedly and sparsely punctate, the setse rather short, fine and recumbent, the series apparently feebly impressed. Abdomen shining, minutely, rather densely and unevenly punctate. Anterior coxae separated by fully one-third their own width ; anterior tibiae strongly and externally produced at apex. Length 3.8 mm. ; width l.U mm. South Carolina. Mr. Morrison. A sino;]e specimen. This species is easil}' distinguishable from striatus, which it perhaps most closely resembles, by its entirely different elytral punctuation and thoracic structure. L,. californictlS n. sp. (Crotch MS.). — Rather slender, parallel, some- what strongly depressed, castaneous to piceous-black, strongly shining ; pubes- cence not conspicuous. Head transverse, somewhat coarsely and densely but shallowly punctured, the epistomal suture deep, transverse, the epistoma short, almost impunctate, polished ; eyes rather small, convex ; antennae slender, compact, almost glabrous, one-half longer than the head, the club small and slender. Prothorax as long as wide, feebly narrowed from apex to base, the apex broadly, strongly arcuate, the base subtruncate ; sides straight, minutely denticulate throughout ; apical angles right, not rounded, basal slightly obtuse, minutely denticuliform and prominent ; disk feebly convex, broadly, feebly impressed in the middle and finely canaliculate near the base, coarsely punctate, the punctures not very dense, shallow, becoming fine and sparse anteriorly especially toward the middle ; pubescence coarse but sparse. Elytra a little less than three times as long as the prothorax and but very little wider, a little more than twice as long as wide, parallel, the sides straight, feebly convergent and arcuate toward apex, the latter rather nar- rowly subtruncate ; humeri right, scarcely at all rounded, distinctly exposed ; disk moderately convex, polished, rather finely, sparsely punctate, the punc- tures deep but narrow and elongate, arranged in subeven single rows except toward the suture and base, where they are confused, the intervals not perceptibly punctate, the coarse sparse recumbent setae entirely filling the punctures and rather irregularly distributed. Abdomen polished, excessively minutely and sparsely punctate. Anterior coxae widely separated, the pro- sternum polished and almost completely impunctate. Anterior tibiae strongly broadening toward apex, the apical angle acute and distinctly prolonged out- wardly. Length 2.2-2.5 mm. ; width 0.65 mm. Coleopterological Notices, TIL 15 California (Fort Yuma). Mr. H. F. Wicldiam. One of the two specimens before me has the prothorax more strongly narrowed behind than the type above described, the differ- ence being probably sexual in nature. It will be observed that the characters of this species are quite composite, the outer apical angle of the anterior tibiae being prolonged and acute, the elytral punc- tures distinctly serial in arrangement, and the anterior coxa? widely separated. It is the smallest of the genus known to me from our territories. L.. Clirtlllus n. sp. — Parallel, rather depressed, pale brownish-testaceous throughout, moderately shining, tlie vestiture coarse, yellowish, moderately long and dense and somewhat conspicuous. Head rather coarsely, very densely punctate, the epistoma less densely so, the suture very deep, broadly arcuate ; eyes moderate in size and prominence ; antennse stout, nearly one-half longer than the head, the third and fourth joints subequal and each rather distinctly shorter than the fifth, club small but robust, oval and rather compact. Pro- tliora.r as long as wide, distinctly narrowed from apex to base, the apex broadly, strongly arcuate ; base very feebly arcuate ; sides straight ; apical angles very slightly obtuse, not rounded although slightly blunt, basal more broadly obtuse and decidedly blunt ; disk feebly convex, broadly feebly impressed in the middle except toward apex, with a fine deep canaliculation near the base, moderately coarsely, very densely punctate, a little more sparsely so near the apical margin. Elytra two and one-half times longer than the prothorax and scarcely at all wider than the latter, not distinctly more than twice as long as wide, the apex broadly, abruptly and obtusely rounded ; humeri right, not rounded but a little blunt ; sides straight ; disk rather closely, confusedly punctate, with two or three feebly defined, narrow, imjjunctate lines on each. Aluhmen polished, minutely and very sparsely punctate. Anterior cox?e rather widely separated, the prosternum polished and almost impunctate, the hypo- mera rather finely and very densely so throughout. Anterior tibiie gradually much broader from base to apex but with the exterior angle not at all pro- duced outwardly. Length 2.7 mm. ; width 0.8 mm. California. The two or three narrow, slightly oblique, impunctate lines on each elytron, is a character which is also sometimes observable in parallelopipedus and punctatus but much less distinctly. The present species differs from cah'forvicus in its broader form, denser punctuation especially of the hypomera and elytra, in its more nar- rowly separated anterior coxae, and in its uneverted exterior apical angles of the anterior tiljiiie, as well as in its stouter antennae with much larger club and in its slightly larger but less convex eyes. L. lounclatus Lee. from Cape San Lucas is a remarkably aberrant 16 Coleopterolocjical Notices, III. species, broader and more convex in form than any of the others, and with the elytra narrowed from apical third, more narrowly sub- truncate and broadly arcuate at apex. The head is transverse, with the eyes moderate in size and strongly convex, the antennte stout, nearly normal in size and structure but with the club parallel, the epistomal suture very fine and scarcely perceptibly impressed. The prothorax is much wider than long-, nearly as wide as the elytra, feebly narrowed from apex to base and with the sides feebly, evenly arcuate throughout, the disk being feebly impressed in the middle toward base. The elytra are not quite twice as long as wide, very coarsely deeply and confusedly punctate, the punctures toward base becoming dense and subcoalescent. The abdomen is polished, minutely and sparsely punctate, the prosternum polished, rather strongly but sparsely punctate, the process being rather broad between the coxte. The anterior tibiae have the exterior apical angle prolonged outwardly and acute. The head and pronotum are rather coarsely and densely and unusually deeply punctured, and each puncture of the entire upper surface bears a short robust erect seta, which is coarsely plumose or bushy in structure. The feebly marked epistomal suture, parallel antennal club and peculiar vestiture may perhaps Avarrant the generic isolation of this species, in w^iich event the name Trogoxylon Lee. could be appropriately adopted for it. ELATERID.E. CHALCOLEPIDllJS Esch. The following species belongs near webhi Lee, but is much larger : — • C apaclieaniis n. sp. — Moderately slender and convex, smooth, polished, intense black throughout, clothed rather densely with small robust recumbent and squamiform hairs, which are strongly convex and finely pointed, dark bluish in color, giving a deep violet-blue bloom to the surface, the lateral edges of the pronotum rather broadly, and of the elytra very narrowly, clothed with dense white recumbent pubescence, the white border abruptly limited. Head strongly impressed, rather coarsely, deeply, sparsely punctate, the interspaces very finely, densely piinctate ; antennse short, two- thirds as long as the prothorax, pruinose with violet-blue, the third joint but slightly shorter than the fourth. Prothorax one-fifth longer than wide, in form nearly as in ivebhi, veiy finely, moderately closely punctate throughout and with scattered coarser punctures anteriorly, especially toward the sides. Scutellum a little wider than long, polished. Eli/tra in form and relation to Coleopterological Notices, III. 17 the prothorax nearly as in vehhi, polished, very minutely feebly and rather sparsely punctured, with somewhat uneven, completely unimpressed series of fine, rather distant punctures. Under surface polished, pruinose with violet- blue toward the sides, minutely, feebly pnnctulate. Length 36.0-38.0 mm. ; width 12.0-12.5 mm. Arizona (Fort Apache). This species differs from webbi, in addition to its very much larger size, in the decidedly longer third antenna] joint in the male, more minutely punctulate surface with the pronotum coarsely punctate anteriorly, in the strong impression of the head, in the abruptly limited and much narrower marginal white vittte, and in the sparser and deep violet-blue vestiture, the latter being extremely dense, paler and olive-green in webbi. Together with webbi, it belongs to Section III of Candeze, and in the vicinity of circumducfus, from which it differs in its entirely flat and not alternately convex elytral intervals. SCARAB.EID^E. POLYPHYLLA Harris. The western species which are homologues of decimlineata in ornamentation, may be easily identified as follows: — Antennal club of the male very large, fully three times as long as the stem ; vestiture more or less strongly squamiform. Antennal club of the female nearly as long as the entire stem; pygidium in both sexes pilose and very sparsely squamose speciosa Antennal club of the female about one-half as long as the stem; pygidium in both sexes densely squamose, not at all pilose, with a narrow denuded median line decemliiieata Antennal club of the male much smaller, not more than twice as long as the stem ; vestiture less strongly squamiform. Pygidium of the male witli the edge strongly reflexed at and toward the apical angle ; elytral vittse always dense and distinctly limited ; color generally castaneous ; spurs of the hind tibije extremely unequal, the longer nearly twice as long as the shorter and generally bent...ci*inita Pygidium of the male with the edge not reflexed at apex ; elytral vittse more or less unevenly disintegrated ; color piceous-black ; spurs of the hind tibije much sjnaller, straight and subequal diffracta My series of decimlineata is very full, embracing specimens from Puget Sound, California, New Mexico, Texas and San Luis Potosi, and throughout this region there is but slight variability exhibited in cither sex. Speciosa is a remarkable species, distinct from dccim- 18 Coleo2:>terolo(jical Notices, II L lineata in its larger size, broader and more depressed form and sparser vestiture, in addition to the characters given in the table. Crinita seems to be comparatively limited in range, all the speci- mens which I have seen being from Southern California. The following is allied to crinita: — P. iliffracta n. sp. — Oval, strongly convex, piceous-black, polished, the vestiture consisting of very narrow, extremely sparsely scattered scales inter- mingled with longer erect hairs on the pronotum, the latter trivittate, each elytron with a very narrow sutural and three discal vittse of denser white scales, also a short humeral vitta which is more or less evanescent, but some- times prolonged, the elytral vittse more or less disintegrated and uneven. Head coarsely, densely punctate, the clypeus broadly reflexed, extremely broadly, feebly bisinuate at apex and very densely clothed with yellow squa- mose pubescence. Prothorax twice as wide as long, the apex broadly emargi- nate and much narrower than tlie base ; sides broadly subangulate ; lateral vitta interrupted anteriorly. Elytra about three times as long as the protho- rax, and, in the middle, one-third wider than the latter, rather finely, sparsely punctate and subrugulose. Pygidium slightly wider than long, very densely squamulo-pubescent except toward the sides, where it is very sparsely so, also with a subdenuded median line. Length 21.0-24.0 mm. ; width 10.3-11.3 mm. New Mexico (probably near Las Yegas). The two specimens before me are males; there is another in the cabinet of Mr. Jiilich in which the elytral vittse are still more dis- integrated. The antennal club of the male is still somewhat smaller than in crinita. Siibuittata and hammondi of LeConte are easily distinguishable from each other by the antennal character separating decimlineata and crinita. The male club in siihvittata is fully three times as long as the stem, and in hammondi but slightly more than twice as long as the latter; there are differences also in the general character of the elytral ornamentation, form of the clypeus, size and other characters, showing that the two species are without doubt dis- tinct. Mr. Dunn, who has taken both of them abundantly, states that they are never found together. THYCE Lee. With increased care in collecting, the species of this interesting genus are becoming somewhat numerous on the Pacific coast, where they replace Lachnosterna to some extent. The species appear to be more nocturnal than crepuscular in habit, and, although proba- Coleoj)lerological Notices, III. 19 bly constituting a moderately large genus, are unquestionably much less numerous than those of Lachnosterna. The two following species have been received since my last refer- ence to the genus: — T. 'blaiHdelli n. sp. — Robust, moderately convex, form nearly as in fossifjer, rather shining, pale rufo-castaneons in color, the humeri and under surface blackish ; vestiture pale ochreous in color. Male. — Head, excluding the eyes, subquadrate, but slightly wider than long, very densely clothed with short robust pubescence and long erect hairs ; clypeus moderately reflexed, very feebly sinuate, the angles broadly rounded; antennje moderate, the club slender, straight, a little shorter than the stem ; fourth joint of the maxillary palpi unusually robust, oval, twice as long as wide, about three-fourths as long as the antennal club, the groove wide, deep, extending from base to apex, two and one-half times as long as wide, the bottom broadly, evenly concave and alutaceous in lustre. Prothorax two-thirds wider than long, broadly lobed at base and subangulate at the sides, some- what coarsely and densely punctate, clothed rather densely with robust squamiform pubescence and fine, moderately long erect hairs. Scutellum densely punctate and squamose. Elytra about one-third longer than widti and nearly one-half wider than the prothorax, the apex broadly subtruncate ; sides feebly arcuate ; humeral callus rather prominent ; disk shining, moder- ately densely and unevenly punctate and subrugulose, the punctures some- what strong, the vestiture consisting of short recumbent moderately densely placed hairs, which are robust but not at all squamiform. Pygidium finely, densely punctate and clotlied like the elytra. Abdomen finely, densely punc- tate and very densely squamulo-pubescent, the vestiture whiter than that of the upper surface ; sterna with the usual long silken pile. Legs rather short, the posterior tarsi distinctly shorter than the tibiie ; ungual teeth of the corresponding tarsi vei'y unequal, the anterior twice as long as the posterior. Length 20.0-23.0 mm. ; width 9.4-11.0 mm. California (Coronado, San Diego Co.). Dr. F. E. Blaisdell. This species, which is represented by the male only, is somewhat allied to fossiger, but differs in its more robust and less densely placed elytral vestiture, shorter, much broader terminal joint of the maxillary palpi and in its shorter posterior tarsi. I have before me a female, pale brownish-rufous in color, strongly shining throughout, with the elytral pubescence excessively fine and sparse, much shorter and finer than in squamicollis, but about twice as dense as in that species. It was taken at Los Angeles and probably represents still another species which it would not be advisable to describe in the absence of the male. It may possibly be the female of the present species. 20 ColeopleroJogical Notices, III. T. squamosa n. sp. — Oblong-oval, strongly convex, piceous-black ; integuments shining. Male. — Head densely punctate, clothed with long erect hair and shorter recumbent squamiforni hairs, the vestiture of the clypeus a little sparser; vertex not tuberculate ; clypeus broadly, feebly sinuate, strongly reflexed, the angles obtuse and but slightly marked ; antenn* moderate, the club nearly three-fourths as long as the stem ; fourth joint of the maxillary palpi very long, fully one-third longer than the antennal club, with a narrow, very deep, parallel-sided groove throughout the length. Prothorax one-half wider than long, the apex broadly, evenly emarginate, fully one-half as wide as the base, the latter broadly subangulate ; sides broadly subangulate, the margins strongly reflexed toward base, feebly serrate ; apical angles narrowly rounded, basal rather obtuse and broadly rounded ; disk very strongly con- vex, narrowly impressed along the middle, coarsely, densely punctate, clothed with long erect hair and long robust recumbent and squamiform pubescence, which is dense along the median line except near the base. Scutellum densely punctate and squamose. Elytra one-third longer than wide, one-third wider than the prothorax, subparallel; sides feebly arcuate ; humeri rounded ; apex broadly subtruncate ; disk finely, somewhat densely punctate and clothed with distinct pointed scales. Pygidium slightly wider than long, convex, deusely clothed with long narrow scales and short hairs. Abdomen somewhat densely clothed with elongate scales and short hairs, the sterna densely pilose. Legs moderately slender ; hind tarsi fully as long as the tibise, with the tooth of the anterior claw nearly twice as long as that of the posterior. Female. — Larger and stouter than the male, the vertex tuberculate, the antennal club small and oval, the fourth joint of the maxillary palpi three- fourths as long as the latter, elongate-triangular, with a narrow deep elongate groove not quite attaining the base or apex ; pygidium much wider than long ; anterior tibiae robust ; hind tarsi two-thirds as long as the tibiae, the teeth of the claws small and moi'e nearly equal. Vestiture throughout consisting of minute recumbent hairs, sparsely j^laced, with erect hair as in the male. Length 20.0-23.0 mm. ; width 9.3-11.3 mm. California (Sau Luis 01)ispo Co.). A distinct species, somewhat related to harfoi'di, but easil}^ dis- tinguishable by many characters of both sexes. The tubercle of the vertex is, throughout the genus, partieularl}^ characteristic of the female. CERAMBYCID.E. ERGATES Serv. Subgen. Trichocnemis Lee. The principal character upon which reliance was placed in sepa- rating neoinexicanus from spiculatus, is rendered somewhat doubt- Coleopterological Notices, HI. 21 fill from the fact that similar differences, in the male sexual charac- ters at the apex of the abdomen, are observable in specimens appa- rently taken in the same locality. I have observed them in examples said to have been collected in Oregon, and forming part of the cabi- net of Mr. Ulke, and Dr. Horn states (Tr. Am. p]nt. Soc, XYIlf, p. 41) that they are equally visible in specimens in his own cabinet taken in Vancouver Island. Nevertheless tljcre are some circumstances which lead me to believe that this is not a case of ordinary fortuitous variation, the chief of which is the apparent want of any known male specimen in which the modification of the fifth segment is truly intermediate between the forms figured on Plate lY, Vol. V, of these Annals. Another singular fact is the remarkable disparity in general form and several important structural characters, as exhibited in the assumed male type of spiculatus — represented by a specimen in my cabinet taken near the shores of Coeur d'Alene Lake, Idaho — and the specimens taken by Mr. Meeske at Las Vegas, New Mexico. Not being able, therefore, to be fully satisfied that the species described by me as neomexicanus is actually the same as spiculatu.s, it seems only right that the question should be held in abeyance until more material can be collected in both of these, as well as in other, localities. When this is done, and if it be then proved tliat the two names are truly synonymous, I believe that it will be demonstrated at the same time that the male of spiculatus is dimorphous.' PRIO]VlJ§ Geoff. The following species is allied to imbricornis: — P. debilis n. sp. — Narrow, subparallel, rufo-testaceons, the elytra pale brownish flavate, thin and almost coriaceous ; lustre moderately shining. 1 Since this was written I have compared the females of the two forms in question, and find that the mandibles of spiculatus are bidentate internally, the teeth being situated before and behind the middle respectively, while in neomcxianius there is but one tooth, situated at the middle ; in the latter the basal joint of the antenn;e is much shorter than in the former in both sexes, but especially in the female. Having in mind the comparative constancy of female structural characters, these observations tend to materially strengthen my original position, in regarding the two specimens of spiculatus and four of neomexicanus which I have before me, as representative of two distinct but rather closely allied species. Spiculatus inhabits the Pacific districts, extend- ing inland toward the north and descending along the Rocky Mountains as far as Colorado ; to the southward of this limit it is replaced by neomexicanus. 22 Coleopferological Notices, III. Head coarsely, deeply punctate, sparsely so behind ; eyes separated above by three-fourths of their own width ; antennae (male) two-thirds as long as the body, nearly as in unhricornis, 18-19 jointed. Prothorax more than twice as wide as long, two-thirds wider than the head and three-fourths as wide as the elytra ; base and apex equal, transverse, each feebly sinuate laterally ; sides parallel, feebly dentate at base and apex and also just before the middle ; disk rather finely and sparsely punctate. Elytra twice as long as wide, parallel, the sides feebly arcuate, obtusely rounded behind, narrowly dehis- cent from basal thii'd or fourth ; inner apical angle obtuse, with scarcely an indication of tlie everted tooth of imhriconiis; disk coarsely, deeply, subrugu- losely punctate. Legs slender, posterior tarsi vary slender, the under surface densely pubescent only in two small spots at the apices of joints one to three. Length 20.0-24.0 mm. ; width 8.0-9.5 mm. Indiana ; Missouri ; Kansas. Represented by a very homogeneous series of seven male speci- mens from the Levette cabinet ; I have not seen the female. This species is allied to imbricornis, having nearly the same antennal structure, but differs in its much smaller size, narrower, more parallel and less convex form, less chitinized and paler elytra, in the more widely separated eyes and in the vestiture of the hind tarsi. In the normal forms of imbricornis — for there seems to be at least one undescribed variety of this species before me — the eyes are separated above by much less than one-half of their own width, and the posterior tarsi are densely pubescent throughout joints one to three, in a widely divided line except toward the base of the first joint. The upper surface of the antenna? is much more coarsely and sparsely punctate throughout in debilis than in imbricornis, this being one of the most striking and constant of the differential characters. TETROPIUM Kirby. The species before me may be recognized as follows — the char- acters throughout being taken from the female, except when other- wise mentioned : — Elytra wider than the prothorax ; third antennal joint in the male much longer than the second. Third antennal joint (female) pyriform, unusually short, scarcely twice as long as wide ; pronotura very sparsely punctate except laterally ; elytra generally pale cinnaniopteriliu Third antennal joint (female) much more elongate, always distinctly more than twice as long as wide ; pronotum very densely punctate. Coleopterological Notices, III. 23 Pronotnm with a narrow and abruptly limited median impunctate area toward base, which is subcarinate ; elytra generally pale. paralleliini Pronotnm without a median impunctate area except narrowly and vaguely toward base ; elytra usually concolorous. Sides of the prothorax broadly rounded ; pygidium evenly parabolic. sclt^^'arzian ii in Sides of the prothorax vaguely subangulate in the middle, the punc- tuation very fine, extremely dense ; pygidium triangular witli the apex narrowly subtruncate velu till Hill Elytra not wider than the prothorax ; second antennal joint of the male but slightly shorter than the third, the latter equal in length to the fourth. parviiliiiii The forms of Tetropium here mentioned seem certainly worthy of recognition, and as far as can be perceived are as distinct as is usually the case in the allied genera. The color of the elytra varies, it is true, as is usual in this part of the Cerambicidse, but the char- acteristics of sculpture and structure upon which the species have been separated, are of more permanent value. The genus will probably prove to be more fully developed in our fauna than in the European. T. parallelimi n. sp. — Elongate, moderately convex, parallel, piceous- black, the elytra paler and uniform red-brown, rather dull throughout, the pubescence short, very dense. Head densely punctate, the longitudinal fron- tal groove feeble ; antennae nearly one-half as long as the body, moderately incrassate toward base. Prothorax slightly wider than long, the apex and base truncate, the former much the wider ; sides broadly, obtusely angulate at the middle ; thence feebly convergent to the apex, more strongly so to the base and almost straiglit ; disk longitudinally, distinctly impressed in the middle, finely, very densely punctate, extremely densely so laterally and toward base except along a narrow tumid median line. Scutellum shining, finely, rather densely punctate. Elytra two and one-half times as long as wide, about one- fourth wider than the prothorax, the apex obtusely and abruptly rounded. Legs moderate in length, rather densely pubescent. Pygidium triangular, with the apex subtruncate. Length 12.0-14.0 mm. ; width 3.3-3.8 mm. J . Colorado; New Mexico. Represented by three females which agree perfectly among them- selves. Parallelum slightly resembles cinnamopterum, but differs in its larger size, more elongate el^'tra and in the characters given in thetaljle; it is more southern in habitat Xh?ii\ cinnamoj)terum, which is represented before me by both sexes from Canada and 24 Coleopierolocjical Notices, III. New Hampshire. In the male of cinnainopterinn the pronotal punctuation is still sparser than in the female. T. SCli^l'arzianiini n. sp. — Robust, the elytra somewhat depressed, piceous black and rather dull throughout, the pubescence short and dense. Head moderately densely and somewhat unevenly punctate ; antennje nearly one-half as long as the body, the second joint nearly two-thirds as long as the third, the latter feebly swollen toward apex. Prothorax but little wider than long, the apex wider than the base, both truncate ; sides broadly, strongly arcuate, becoming convergent and straighter toward base and aj)ex ; disk con- stricted just before the base, rather strongly, deeply punctured throughout, the jiunctures generally separated by about twice their widths but denser laterally and toward base, with a more or less narrow uneven impunctate area toward base, which is not at all tumid. Elytra not more than twice as long as wide, in the middle nearly one-half wider than the prothorax, slightly dehiscent near the apex and obtusely subtruncate ; sides parallel and broadly arcuate ; disk with indistinct traces of the usual two fine ridges. Legs mode- rate in length. Length 14.0 mm. ; width 4.5 mm. Michigan (Marquette). Mr. Schwarz. This species somewhat resembles velufinum, but differs in its shorter and more robust form, more broadly rounded sides of the prothorax and coarser, sparser pronotal punctuation. It is widely different from cinyiamopteriim in all these characters, as well as in its broader and more parabolic terminal dorsal segment, and much longer antennas. The description is drawn from the female, and all comparisons are made in the same sex. T. parTllluni n. sp. — Parallel, depressed above, black, the antennje, legs and elytra more or less pale ; pronotum liighly polished ; elytra dull ; pubescence short, dense on the elytra. Head finely, sparsely punctate, strongly tumid between the antennse and longitudinally, deeply sulcate ; antennae two-thirds as long as the body, stout, gradually, finely attenuate, the basal joint one-third longer than wide, second but very slightly shorter than the third, obconical. Prothorax slightly wider than long, the apex broadly sinuate in the middle, nearly one-half wider than the base, the latter truncate; sides subangulate just before the middle ; disk broadly impressed along the middle, constricted just before the base, smooth, highly polished, finely, extremely sparsely punctate, the punctures larger and moderately dense only on the flanks. Scutellum narrow, polished, with a few minute widely distant ijunctures. Elytra parallel, two and one-half times as long as wide, broadly rounded at apex near which they are dehiscent, each elyti'on rounded ; sides straight ; disk not wider than that of the prothorax, with vague traces of the usual fine ridges. Zer/s short, the- hind femora robust. Length 8.0 mm. ; width 2.2 mm. Coleopterological Notices, III. 25 Indiana. The description is taken from the male. The species resembles cinnamopterum, but differs in many characters, chief!}- mentioned in the table, but also in its shorter and more robust legs. The punctuation at the sides of the prothorax is coarser and sparser, and the terminal joint of the antenna; is quite different, being shorter and without a well-marked cylindrical process at apex ; the basal joint, also, is much shorter, although this latter character is less important. HYLOTRUPES Serv. The following species has been well known in our cabinets for many years, and has given rise to much discussion as to its proper value. It is generally conceded to be a well-marked variety of ligneus, but certain characters not heretofore dwelt upon lead me to believe that it is specifically distinct. H. litigiosus 11. sp. — Black, shining, the pubescence rather long, sparse ; elytra with two transverse fascise, one before basal third, the other just behind the middle, both broadly interrupted at the suture and not attaining the lateral margins. Head as in liliqtlU% n. sp. — Oblong, subparallel, rather depressed, black throughout, the coxje alone pale testaceous, moderately shining, each elytron with two narrow fasciss, oblique toward the suture, the anterior at basal third feebly and posteriorly -so, the posterior at apical fourth anteriorly and strongly. Head somewhat finely, eomt'usedly punctate ; antennae in the male slightly longer than the body, slender, but slightly stouter toward base, the second joint less than one-half as long as the third, the latter slightly longer than the fourth and a little shorter than the fifth, in the female more than three- fourths as long as the body. Pmthwax very slightly wider than long ; apex and base truncate, the former slightly the wider ; sides arcuate ; disk widest at about the middle, finely punctate, the punctures dense and scabrous later- ally, very sparse toward the middle. Jih/tra feebly narrowed from base to apex, and, at base, but little wider than the prothorax in the male, parallel and much wider than the latter in the female, finely, very densely punctate, much more sparsely so in basal third. Legs long, with the femora strongly pedunculate and clavate in the male, shorter and a little more slender in the female. Length 7.2-7.6 mm. ; width 2.3-2.5 mm. California (Santa Clara Co.). Mr. Harford. The three specimens represent a species allied to vaiHus, but differing in the much finer, sparser punctuation of the pronotum, denser punctures of the elytra, with shorter finer pubescence, longer antennae and much more oblique posterior fascisB. This species bears no resemblance to decussatus of which I have Coleopterological Notices, III. 27 a large series; the body is more robust, the femora more clavate, and the antennal joints much more elongate. CHROTOIHA 11. gen. Body elongate, densely pubescent, the elytra with small denuded spots. Head not quite vertical, the front feebly concave between the antennae, longi- tudinally and finely sulcate, divided from the epistoma by a rather fine but distinct sulcus ; eyes deeply emarginate, large, coarsely faceted ; palpi slightly unequal, elongate, slender, the last joint elongate, nearly parallel, the apex minutely, transversely ti'uncate ; antennal tubercles slightly and obtusely prominent ; antennae (female) two-thirds as long as the body, the third joint very long, slender, slightly enlarged near the apex, three-fourths longer than the fourth, the latter slightly shorter than the fifth, joints five to eleven sub- equal in length, compressed, the edges very acute, the flat sides feebly swollen along the middle, the apex acutely angulate and very prominent but not spiuose internally, tenth joint slightly shorter than the ninth or eleventh, the latter with a small conical apical process. Prothorax without lateral spine and with five dorsal callosities. Scutellum acutely triangular. Elytra witli a stout acute sutural spine. Front coxal cavities angulate externally, sepa- rated by a narrow but distinct prosternal lamina. Middle coxffi distinctly separated, the cavities open externally. Metathoracic episterna moderate in width, scarcely visibly narrowed from base to apex. Legs short, slender, the basal joint of the hind tarsi rather longer than the two following combined. This genus, together with Brothylus and Osmidus of LeConte and Perilasins Bathes, constitutes a group of species which is very difficult to treat; they are all allied to the European Ilesperophanes. Chrotoma differs from Brothylus and Osmidus in the peculiar elon- gate subparallel form of the last joint of both palpi, and from Peri- lasins, to which it is probably more closely allied, in the slender, almost parallel femora, absence of lateral thoracic spine in the female, and very different disposition of the dorsal callosities, appa- rently also in the form of the terminal palpal joints. C. dlinniana n. sp. — Parallel, moderately, evenly and cylindrically convex, piceous-black throughout, the antennae and legs concolorous, the elytra with a marginal and discal vitta of pale rufo-testaceous, feebly evident through the dense vestiture and which become more distinct toward base ; pubescence moderate in length, coarse, recumbent, very dense throughout the body and legs, pale grayish-white, the small elytral denudations bearing long erect flying hairs, the latter also present rather densely on the prothorax and sparsely on the legs and toward the base of the antennae. Head three-fourths as wide as the prothorax, the antennae (ilothed with fine recumbent ashy pubescence toward base, which becomes slightly darker and excessively minute 28 Coleopterological Notices, III. and dense toward apex. Prothorax very slightly wider than long, the base and apex equal, truncate, the sides evenly and rather strongly arcuate ; disk with four small denuded callous spots, which are granulato-rugose but not elevated and arranged in a transverse arc at about the middle of the length, the fifth sliglitly more elongate-oval on the median line at basal third; on each side of the latter there is also visible a minute callus, which is probably not constant, the median callus slightly impressed and polished. EJijtra about one-fifth wider than the prothorax, parallel, the sides straight, the apex abruptly, broadly rounded, subtruncate in the middle ; disk with fine, rather dense punctures, almost completely concealed by the vestiture, the denuded spots small, numerous, arranged without order, smooth, polished and flat. Length 16.5 mm. ; width 4.3 mm. Texas (El Piiso). Mr. G. W. Dunn. The vestiture is longer, coarser and denser than in Brothylus, and almost completely et)nceals the sculpture. The species is repre- sented l)v a single female. ELrAPHIDlOIV Serv. HypermaUus Lac. ; Anefhis Leo. The following species belong-s near irroratum and mucronatum, but has the outer joints of the antenn;v strongly and finely carinate along the middle of th(! flat sides, being thus a highly typical mem- ber of the grouj) of species generically separated by Dr. LeConte under the name Aueflus; it will be noticed that the outer joints of irroratum are also strongly carinate. In fact Aneflus not only cannot be regarded as a genus, but apparently does not form even a distinctly marked group, the tendency to carination being apparent in the majority of species and to a very variable degree, so that it is impossible to assign any limits to the group. E. ai'izoiieiise n. sp. — Form as in irroratum, castaneous throughout, scarcely more shining than mucronatum; pubescence very short and sparse, fiuelj' and rather sparsely marmorate on the pronotum and elytra with small irregular patches of denser pale yellowish pubescence, four of the spots of the pronotum forming a transverse row just before the middle. Head coarsely, densely punctate; antennje (male) about two-fifths longer than the body, stout, third and fifth joints equal in length, the fourth distinctly shorter, three to five strongly spinose internally, the remainder with a small inner and outer si)ine at apex, joints eight to eleven with a fine strong median carina along their compressed sides. Prothorax very nearly as long as wide ; apex and base subequal, truncate ; sides broadly, very obtusely subangulate at or just behind the nuddle ; disk with a small, elongate, almost impunctate median callus just behind the middle, and a subcallous line at lateral fourth Coleopterological Notices, III. 29 extending from apical two-fifths to the hase, which is luore coarsely punctate and more pubescent; otlier regions dull, coarsely punctate, the punctures densely crowded and themselves finely densely punctate, forming an intricate hut coarse sculpture. Scutellum densely pubescent. Elytra a little less than three times as long as wide, at base distinctly wider than the prothorax ; sides feebly convergent from base to apex, the latter truncate, the outer spine very short and broadly obtuse, the sutural short, narrower and more acute ; disk sparsely punctate, the ^lunctures very coarse toward base but fine in apical half. Under surface nearly as in mucroimtum, the legs longer and the femora much stouter in the male, not spinose ; posterior tibiie carinate as in irrorubescence fine, long and very dense on the prouotum, shorter but dense on the elytra. Head rather small ; antennae (male) nearly one-half longer than 32 Goleopterological Notices, III. the body, the third joint as long as the prothorax, (female) two-thirds to three-fourths as long as the body, slender, not distinctly compressed, the intermediate joints from three and one-half to four times as long as wide. Prothorax from one-half (male) to nearly once (female) wider than long, the lateral tubercle strong, the apex quite distinctly narrower than the base ; disk extremely densely punctate, a very short narrow line in the middle usually more or less impunctate. Elytra at base as wide as the prothorax, each elytron narrowly truncate at apex and obtusely but very distinctly angulate exter- nally ; disk of each with the usual three fine lines, rather finely, very densely punctate toward apex, the punctures still dense but coarser toward base. Length 15.0-19.0 mm. ; width 4.4-5.7 mm. New Mexico. Related to intermedins, but larger and with much finer, denser punctuation, and black legs and antennae. In intermedius the elytra are rounded behind and not truncate and angulate or even prominent externally as in longipennis ; this is an unusual char- acter in the present genus, but may be perceived also to a less degree in hirtipes Lee. Four specimens from the Levette cabinet. C. crassipes n. sp. — Robust, subparallel, black to piceous-black through- out, the elytra and entire abdomen pale brownisli-testaceous ; lustre of tlie elytra rather strongly shining as in punctatus; pubescence long, dense and pilose on the pronotum, rather long subrecumbent dense and conspicuous on the elytra, pale throughout. Head rather small, tlie antennse (male) very long and slender, much longer than the body, the third joint slightly shorter than the prothorax. Prothorax coarsely, extremely densely punctate, with a small indefinite median spot which is sparsely punctate ; lateral tubercles moderate ; disk (male) one-half wider than long, tlie apex distinctly narrower tlian the base. Elytra at base distinctly wider tlian any part of the protliorax, two and one-third times longer than wide, rounded behind, each elytron very narrowly feebly sinuate at the suture ; sides rather strongly convergent from base to apex ; disk very coarsely punctate, the punctures becoming smaller but extremely dense toward apex, the three fine lines distinctly traceable. Legs black, the anterior and intermediate very short, with the tarsi dilated, the posterior much longer, with the tarsi two-thirds as long as the tibise, robust, the second joint nearly one-half longer than wide. Length 14.0 mm. ; width 4.5 mm. Washington State. A single male example from the Levette cabinet. This species is intermediate between punctatus and iutermedius, possessing the black legs and antennaj and robust tarsi of the former, and the long slender antennte of the latter; it is however abundantly distinct from either. The male is much stouter than the corresponding sex Coleopterological Notices, III. 33 of intermedins, and, in the latter, the posterior tarsi arc very short but slender, with the second joint not longer than wide. C. iiitidicollis n. sp. — Slender, strongly convex, subcylindrical, strongly shining throughout, intense black, the median parts of tlie meta- sternum and the abdomen pale rufous ; elytra very pale flavate, with a slender fusiform sutural space black ; pubescence rather short and sparse, slightly longer and more erect on the pronotum. Head small ; antenna (male) fully one-third longer than the body, slender. Prothorax two-fifths wider than long, strongly convex and coarsely, not very densely punctate, the apex truncate, much narrower than the base, lateral tubercle small but distinct. Elytra two and three-fourths times longer than wide, at base equal in width to the widest part of the prothorax, the sides very feebly convergent thence to the apex, each elytron narrowly and almost evenly rounded behind ; disk very coarsely, deeply punctate, the punctures well separated toward base and becoming finer but not much closer toward apex. Le^s slender; hind tarsi three-fourths as long as the tibiae, with the second joint a little longer than wide. Length 10.5-12.5 mm. ; width 3.3-3.8 mm. Arizona (Tucson). Mr. Wickham. This species is allied somewhat to pulchellus, but differs con- spicuously in many characters as detailed in the synoptic table ; in addition it may be noted that the prothorax is larger and longer than in pulchdlus, with the extremely slender and acute lateral prolongation of the basal angles much more conspicuous. It is represented before me by four specimens all of which are males. The male appears to be more abundant than the female in all of the species of this genus. SPHiEXOTIIECUS Dup. Ischnocnemis Lee. nee Thorns. The Mexican species allied to this genus form a very perplexing- mixture, and I have several in my cabinet which cannot be satisfac- torily assigned to any of the described genera. The parts most useful in generic identification are the mesosternum, posterior tarsi and scutellum, but the last is probably much the least important of the three. The presence or absence of raised ivory vitt^ is, as remarked by Mr. Bates, a chauacter of subordinate import, and in Sphaenothecus we have species with simple elytral disk like saturalis, others having raised costse, and others again with simple narrow pubescent vittae. Sphfenothecus is allied to Mannophorus, but difi"ers in its protu- 34 ColeopteroJogical Notices, III. berarit and anteriorly vertical mesosternum and generally longer, more finely attenuate scutellura. The true Ischnocnemis has the mesosternum non-protuberant. Our three species may be separated b}^ the following table : — Elytra with raised ivory vittfe bivittatllS Dup. Elytra simple, without raised lines or pubescent discal vittaj, the suture alone narrowly and very evenly vittate, the vitta composed of extremely dense white pubescence. Piceous-black, the prothorax and femora rufous ; elytral punctuation coarse, very sparse, evenly distributed, the pronotal punctures and pubescence not denser laterally sutui'a.lis Leo. Pale rufous throughout, the tibise and tarsi nigrescent ; autennse black, in the male fully twice as long as the body, in the female about as long as the body. Prothorax more transverse and less strongly narrowed ante- riorly than in suturalis, the pubescence very dense toward the sides and apex as well as along the base. Elytra nearly as in suturalis, but more rajiidly harrowed from base to apex, the punctuation coarse, sparse toward the sutural vitta, but thence dense, rugulose and intermingled with smaller punctures in a wide uneven longitudinal area extending almost to the sides, the pubescence longer and denser than in suturalis. Length 11.0-12.5 mm. ; width 3.5-3.8 mm rubeilS n. sp. The male antennae are always much shorter in suturalis than in ruhens, and are generally not more than two-thirds longer than the body, the eyes also are more narrowly separated dorsally than in rubens. The three species agree in the form of the elytral apices which are strongly, very acutely dentiform but scarcely spinose externally. Ruhens was obtained in great abundance by Mr. Dunn in various parts of southern Arizona and California, and suturalis by Mr. Wickham at Tuc;son. STENOSPHEIVUS Hald. With the exception of notatus our species seem to be quite local in distribution ; the following belongs near lepidus Horn : — S. loilgicollis n. sp. — Slender, elongate, subparallel, polished, the elytra slightly less so than the prothorax and minutely evenly reticulate ; body piceous-black, the femora red, piscescent near the apex ; prothorax red, clouded with piceous toward the sides ; pro- and mesosterna red ; pubescence coarse, moderate in length, sparse. Head finely, longitudinally canaliculate ; antennae (male) very slender, fully three- fourths longer than the body, joints three to five spinose internally at apex. Prothorax distinctly longer than wide ; sides broadly, evenly arcuate, gradually convergent anteriorly and Goleopterologieal Notices, III. 35 abruptly so near the base which is much wider than the apex ; disk widest at basal third, with a few fine, widely dispersed punctures toward the sides only. Scutellum small, rounded, densely flavo-pubescent. Ehjtra three times as long as the prothorax, and, at the base, one-fourth wider; sides feebly con- vergent and nearly straight from the humeri to apical fourth or fifth, then gradually more strongly convergent to the apex, each elytron being narrowly truncate, the truncation bisinuate and limited internally and externally by a minute acute dentiform process, which is not sufficiently elongate to be termed spinose ; disk rather finely but deeply, sparsely, evenly punctate throughout, the punctures perforate and without trace of definite arrangement. Length 10.0 mm. ; width 2.5 mm. Texas. A single male, probably received from Mr. Dunn, and without any more definite locality. It differs from lepidus in having- the entire prosternum in "front of the coxie strongly depressed and coarsely densely punctato-rugulose, with the exception of a wide polished apical margin ; in lepidus this space is divided by a polished longitudinal elevation, thus forming two depressed areas. Longi- coUis does not appear to be referrable to any of the described Mexi- can species. XYLOTRECHIJS Chev. The species insignis of LeConte, is remarkable for its pronounced sexual disparity. A few years since I took a series of six speci- mens from some low alder-like trees near the banks of the Trinity River, in Humboldt Co., California, Avhich upon cursory examina- tion seemed to represent a distinct species near insigyns. Subse- quently I received a number of specimens from other parts of the State. The Humboldt specimens are uniformly pale in color, with the prothorax large and transversely subquadrate, and the markings indefinite and more or less confused with the ground color by dis- persion of the pale hairs ; upon close study all of these specimens prove to be males. The female, represented l)efore me by three perfectly homogeneous examples, is black, and has the prothorax narrower and the markings always distinctly and abruptly limited. Although such striking sexual differences are unusual or alto- gether unknown in our other species of this genus, it appears to be a more common condition in the allied Mexican genus Ochra^thes Chev., a seemingly undescribed species of which, represented in my cabinet by a good series, having the markings suffused in the male but distinct in the female. 36 Coleopterological Notices, III. TIIESAI.IA n. gen. This name is proposed for a small species, recently described by Mr. Len,<>- (Ent. Amer., VI, p. 108) under the w&me' Acmseops lisa. Briefly, its characters may be expressed as follows: — Front before the antennre nearly vertical. Antennae long and slender, rather api^roximate and dorsal in their insertion. Eyes moderate, convex, with a small distinct but moderately deep sinnation. Neck strongly con- stricted, the constriction extending entirely across the dorsal surface. Legs moderate, the posterior tarsi rather short, densely pubescent beneath, the basal joint subequal in length to the next two together. The genus Thesalia should be placed between Leptalia and Ency clops in our lists, and agrees with the former in most of its characters. The prothorax differs greatly from either Leptalia or Encyclops, being long and slender, much longer than wide and narrower than the head, rather coarsely and sparsely punctate and not at all im- pressed or canaliculate along the middle. In Encyclojjs coervlea both the head and pronotum are dull and densely covered with a reticulation formed by fine strongly elevated lines. I have before me a single representative of Th. lisa collected in Marin Co., California, by Mr. Dunn. It does not entirely agree with the description given by Mr. Leng, having the pronotum sparsely punctate toward the middle, without a well-defined impunc- tate area, the elytra black with the punctures throughout decidedly sparse as well as extremely coarse and deep, and with the sides feebly convergent from base to apex. The hind tarsi have the two basal joints densely pubescent beneath but not as densely so as the third, and are strongly fimbriate along the sides. The specimen here noted is probably the male of the original type, which is with- out doubt a female. CEXTRODERA Lee. There is before me a specimen which I took on the summit of Mt. Diablo, near San Francisco, which is pale castaneous in color throughout and uniformly and sparsely pubescent. The length is 1G.5 mm., and the prothorax is much longer than wide, strongly constricted at basal and apical fourth, with the apex much narrower than the base and the disk broadly, deeply impressed along the middle. The eyes are remarkably large and the antennai are ColeopteroJogical Notices, III. 37 slight]}' longer than the body, with the joints four to eleven pale testaceous toward base and black in apical third. I think that this is proba))ly the male of C. nevadica Lee, which was described from a unique female. TOXOTUS Serv. T. lateralis n. sp. — Rather short and stout, moderately shining, black throughout the body, legs and autennse, the abdomen rufo-testaceous and the elytra with a pale narrow marginal vitta which does not quite attain the apex ; pubescence short, cinereous, rather sparse, longer but not much denser on the prothorax. Head rather finely densely and conflueutly punctate, broadly tumid between the eyes, the latter rather large and convex ; antennae but just visibly shorter than the body, rather stout, compressed, the fourth joint nearly two-thirds as long as tlie third and about three-fourths as long as the fifth, the third joint three times as long as wide. Prothorax a little longer than wide, strongly constricted near apical third and basal fourth, the apex four- fifths as wide as the base, broadly arcuate ; sides angularly tuberculate at the middle ; disk finely, densely punctate, the punctures sparser in the apical constriction. Elytra at base nearly one-half wider than the prothorax, two and one-half times longer than wide, the sides very strongly convergent from base to apex and nearly straight ; each elytron narrowly and obliquely trun- cate, the truncature straight, the outer angle acute, not rounded, the inner dentiform ; humeri rather prominent, less than right, narrowly rounded ; disk nearly flat, abruptly perpendicular at the sides, very finely, densely punctate and also with slightly larger widely dispersed punctures. Under surface punc- tured like the elytra, the abdomen more sparsely. Legs slender, moderate in length. Length 13.0 mm. ; width 4.0 mm. California (near San Francisco). The single male specimen which I took at the summit of Mt. Diablo, represents a species somewhat allied to the eastern trimt- tatus Say {vittiger Rand.), but differing in its unusually long, and, at the same time, stout and compressed antennae. The elytral trun- cature is as in trivittatus, but with the sutural tooth much larger and more conspicuous. AWTHOPHH.AX Lee. A. Slltovittata n. sp. — Moderately robust, rather convex, piceou.s-black ; legs and antennae piceo-testaceous ; elytra pale luteo-testaceous, with a broad common sutural and narrow submarginal vitta of piceous-black, the vitta? generally feebly marked and sometimes evanescent ; pubescence extremely short and sparse, on the elytra consisting of very minute erect setoe borne from the punctures. Head finely, densely j^unctate, finely canaliculate be- tween the antennae, the latter three-fourths as long as the body, with the 88 Coleopterological Notices, HI. third joint distinctly longer than the fourth but much shorter than the fifth. Prothorax slightly wider than the head and a little wider than long, the apex very slightly narrower than the base, both feebly arcuate ; sides strongly, obtusely tuberculate at the middle ; disk finely, densely punctate, scarcely at all impressed along the middle where the punctures are sometimes but not always sparser. Elijtra at base not more than one-third wider than the prothorax, about two and one-third times longer than wide ; sides distinctly convergent from base to the apex, which, conjointly, is broadly and evenly rounded ; disk very coarsely and sparsely punctate toward base, the jjunc- tures becoming gradually fine toward apex and along the suture. Length 9.3-11.0 mm. ; width 3.2-4.0 mm. Colorado ? The five specimens before me are without definite indication of localit}", but as they are from the Levette cabinet they were in all probability taken in or near the region above stated. These speci- mens are apparently all males, and the si)ecies appears to be related to tenebrosa, which is described from a unique female. I do not think however that suhmttata can be the male of tenebrosa, for in that case the general direction of the sexual differences, as shown in mirifica by Dr. Horn, would be rather reversed, the elytra in the male of mirifica being almost impunctate, while in the female they are very coarsely so. ACHIJEOPS Lee. The series in my cabinet seem to show that A. subpilosa is a species entirel}^ distinct from lu])ina. The former is extremely sparsely punctate, the pubescence very easily removable, but denser and persistent Ih a very narrow line bordering the elytral suture, giving it a narrowly vittate appearance, while in lupina there is no indication of this sutural condensation, and the discal punctures are between two and three times as dense, the pubescence being much more persistent. The species longicornis and ligata are perfectly identical, and the latter should be regarded as a synonym of the former, not a variety. Gibbula is a synonym of proteus and not a variety, as it is printed in our lists. A. variipes n. sp. — Rather slender, strongly convex, shining, deep black ; antennae dark brown, with the basal joint darker and blackish ; ante- rior legs throughout and the intermediate and posterior femora feebly and suffusedly near the coxae only, pale rufo-testaceous ; pubescence very short and sparse, longer on the anterior portions. Head about equal in width to Coleopterohxjical Notices, III. oi) the prothorax, flattened above, rather coarsely, extremely densely punctate and dull ; sides behind the eyes parallel for a very short distance, then rounded to the neck ; temjtora shorter than the eye ; antennje very slender, subequal in length to the body, third joint much shorter than the fifth and but slightly longer than the fourth, the fifth thicker toward apex than the others. Prothorax slightly wider than long, the apex broadly arcuate, three- fourths> as wide as the base ; sides strongly but evenly arcuate, sinuate near base and apex ; disk narrowly impunctate but scarcely impressed along the middle, rather coarsely, very densely punctate, the punctures generally not in actual contact. Scutellum rather longer than wide, acutely rounded at apex. Elytra at base not quite one-half wider than the prothorax, two and one-half times as long as wide ; sides rather strongly convergent from base to apex, the latter narrowly rounded, not at all truncate ; disk very coarsely, deeply, not closely punctate, the punctures becoming slightly smaller but not denser toward apex, each bearing a very short coarse hair. Legs rather long and slender. Length 8.0-8.8 mm. ; width 2.5-3.0 mm. California (Sta. Cruz Co.). This species is somewhat allied to longicornis and bamlis, but differs in its shorter, more convex form, much coarser, sparser punctuation, shorter, sparser pubescence, and also in coloration ; from atra it differs greatly in the parallel sides of the head behind the eyes, in the distinct basal constriction and prominent basal angles of the prothorax, and in its much more crowded pronotal punctuation. A specimen from Nevada is nearly similar, but has the pubes- cence still more minute and the elytra parallel and scarcely more than twice as long as wide ; this is probably the female of the above-described male. STRAi\GALIA Serv. The sexual characters of this genus form an exceedingly inter- esting study, as they manifest themselves strongly and in several directions. The fifth segment of the male is sometimes very large, dilated and strongly excavated beneath as in virilis, and, to a less degree, strigosa; in addition it will be noticed that this segment is also invariably impressed or excavated beneath toward tip in the female as well as the male, and in sexnotata the impression is (piite as deep in the former as in the latter sex, and involves even more of the surface of the segment. The community of impressions and excavations of the fifth ven- tral segment to both male and female is noticeable in many parts 40 Coleopterologieal Notices, III. of the Heteromera, and I have alluded to it before under the genus Blapstiuus (Ann. N. Y. Acad., V, p. 418). It is probable that this fact has a more far-reaching import than may be apparent to us at present. The antennfe of the male have, on the side at the apex of each of the outer joints, a large elongate-oval depressed area which is glabrous, but over which there are generally scattered a very few coarse spinose setae. These sensory depressions are usually much less developed in the female than in the male, and are sometimes almost obsolete in that sex ; they vary slightly in form and depth in the various species. I take the present occasion to call attention to a species allied to sexnotata, Avhich may be described as follows from the female: — S. montana n. sp. — Moderately robust, rather dull and alutaceous in lustre, pale rnfo-testaceous throughout, the tarsi and three or four terminal joints of the antennae picescent ; elytra each with three black spots arranged as in sexnotata; pubescence rather short, coarse and sparse. //eoJ finely, very densely punctate, a posteriorly angulate area immediately behind the epistoma impunctate and highly polished ; epistoma and labrum finely, sparsely punc- tate and shining ; antennas (female) two-thirds as long as the body, stout, cylindrical, the joints compactly joined toward apex and without trace of sensitive apical areas, third joint one-half longer than the fourth. Prothorax fully as long as the basal width, finely, strongly constricted just behind the apex, the latter truncate and less than one-half as wide as the base, the latter broadly bisinuate ; basal angles laterally produced, acute and prominent ; sides broadly sinuate toward base ; disk immaculate, evenly convex, rather coarsely and sparsely punctate. Elytra at the humeri quite distinctly wider than the prothorax, nearly three times as long as wide, the sides strongly convergent from the rounded humeri to the apex ; each elytron truncate at apex, the truncation but slightly oblique ; disk rather coarsely, sparsely punctate. Under surface finely, sparsely punctate and pubescent. Length 12.5 mm. ; width 3.5 mm. New Mexico (Las Vegas). Mr. Meeske. Immediately distinguishable from the female of sexnotata by the truncate apices of the elytra, and stouter antennae ; the antenna and greater part of the legs are black in sexnotata, but two speci- mens before me from Texas seem to indicate that they may occa- sionally become pale throughout, this not being a character of great importance. The elytra toward apex are much less dehiscent in montana than in sexnotata, and the surface in the former is less shining and more linely punctate. Coleopterological Notices, III. 41 OPIIISTO»IIS Thorns. The species recently described by Bates (Biol. Cent.-Amer. Col., Y, p. 39) as leevicollis is represented before me by three specimens, perfectly homogeneous as regards color, and belonging to the variety designated " 6" (1. c, page 279). These specimens were formerly included in the Levette cabinet, and are labeled "Arizona." This is therefore one of those tropical species of exceptionally extended northern distribution, of which Xystropus caHfornicus Horn, is another notable example. The elytra in 0. laevicoUis are obliquely and rather widely trun- cate at apex, the line of truncation straight and the outer angle very acute but not appreciably produced. The elytral punctuation varies considerably in density, but is generally finer and confused toward apex and very coarse and sublineate in distribution toward base. The humeri in the specimens alluded to are clouded with reddish- testaceous. The intermediate tibiae are quite distinctly clavate.^ LEPTURA Serv. A specimen of nigi^ella Say, from Colorado, before me, has the elytra bright red throughout, with the exception of a narrow and even black marginal vitta in apical third. The three following species appear to be new: — Li. serpentina n. sp. — Rather slender and convex, feebly shining, black throughout, the legs and antenna generally pale ; pronotum with the apical and basal margins bright sulphureo-pubescent ; elytra each with four transverse bands of the same color, one at the base just behind the scutellum narrowly interrupted at the suture, the second just before the middle, third at posterior third, and the fourth near the apex ; under surface clothed with yellow pubescence, the abdominal segments more distinctly so near the apex 1 Some time after the above paragraphs were written, I sent one of these specimens to Mr. Bates, and take the liberty of quoting the following lines from the very courteous letter recently received in reply : — " I have examined your Ophistomis, supposed to be from Arizona, and find it cannot be specifically distinguished from 0. hevicoUis. The punctuation is a little more sparse, but a rather more important diflference is the relative greater length of the elytra, and the shorter outer acute angle of the trunca- ture. I do not consider these differences specific, but note them only as some evidence that the specimen comes from a different locality from those recorded in the Biologia, i. c, Oaxaca to Panama." Annals N. Y. Acad. Sci., VI, Nov. 1891. — 4 42 Coleopierological Notices, III. and sides. Head finely, densely punctate ; antenn;e (male) nearly as long as the body, slender, filiform, the third joint much longer than the fifth, the latter distinctly longer than the fourth, (female) nearly three-fourths as long as the body, with the joints proportioned nearly as in the male. Prothorax about as wide as long, campanulate, with the sides inflated and broadly sub- angulate before the middle, the basal angles acute and strongly produced out- wardly and posteriorly ; disk almost evenly convex, with a small impunctate vitta near the base, rather strongly and somewhat sparsely punctate in the male, densely so in the female. Elytra at base distinctly wider than the pro- thorax, a little more than twice as long as wide ; sides moderately convergent (male), or very feebly so (female) ; apex narrowly and evenly truncate, the truncation but slightly oblique ; disk strongly, rather densely punctate (male), or extremely densely and more finely so (female). Legs rather long and slender. Length 7.0-11.0 mm. ; width 2.0-3.3 mm. Idaho. Greatly resembles trihalteata Lee, and differs from that species in much the same way that nitens Forst. (zebra Oliv.) does from laefa Lee. The form in the male is more slender than in tribalteata, with the elytra less strongly narrowed from base to apex, and with the a})ical truncation much less oblique ; the antennae are much longer and more slender, and the third joint is distinctly shorter in comparison with the next two ; the dorsal punctuation is coarser, deeper and sparser in the male but rather denser in the female, and the transverse bands of the elytra are much narrower. The antennoe are always pale in sefyenfina and intense black in tribal- teata, and the head and eyes are smaller in the former than in the latter. L.. lialdemani n. ap. — Slender and rather convex, intense black throughout tlie body, legs and antennse, the elytral humeri obliquely red ; lustre moderately shining ; pubescence short, sparse and inconspicuous. Head wider than long, the tempora and base nearly as in sanguinea; surface fiat, very densely punctate ; antennje (male) nearly as long as the body, rather stout. Prothorax much longer than wide, as in sanguinea, but much less inflated or subangulate at the middle ; disk rather coarsely, deeply and extremely densely punctate, the punctures in close mutual contact, without distinct median impunctate line except very narrowly toward base, the line generally with a very fine impressed stria. Elytra between two and three times as long as wide, at base nearly one-half wider than the prothorax, the humeri rounded but rather prominent ; sides evenly and rather strongly con- vergent from base to apex and straight ; each elytron narrowly truncate at apex, the truncation slightly oblique and straight or extremely feebly sinuate, the angles obtuse ; disk not very coarsely or densely punctate, the punctures deep and perforate toward base, becoming finer and more or less asperate Coleopterological Notices, III. 43 toward apex, sometimes with traces of two narrow irapunctate lines toward base. Under surface very finely and densely punctate, more conspicuously pubescent. Length 9.0-10.5 ; width 2.5-3.0 mm. ISTew Mexico. The two specimens are males, and are from the Levette cabinet. The species is allied to sanguinea, but differs greatly in coloration and punctuation, and in the more narrowly and obliquely truncate elytral apices. The red humeral maculation is similar in form to that of Acmseops basalts. li, laciistris n. sp. — Body, legs and antennre entirely black, the elytra pale brownish-testaceous, sometimes feebly infuscate near the apex ; lustre moderately shining ; pubescence moderately long, very short on the elytra. Male. — Slender, very convex. Head wider than long, the sides behind the eyes parallel for a short distance ; hind angles right and narrowly rounded ; surface feebly convex, densely and rather coarsely jiunctate ; antennje three- fourths as long as the body, rather stout. Prothomx as in sanguinea, rather coarsely, deeply, very densely pujictate, with a narrow impunctate median line, the punctures nearly but not quite in mutual contact, the interspaces polished. Elytra two and one-half times as long as wide, at base one-third wider than the prothorax ; sides gradually and distinctly convergent from base to apex, the latter very narrowly and obliquely truncate, the truncation deeply sinuate ; disk rather densely and strongly punctate, the punctures be- coming slightly finer toward apex. Length 9.0-11.0 mm. ; width 2.8-3.6 mm. Female. — Moderately slender, smaller than the male, the upper surface much less convex. Head similar in form to that of the male, but with the surface very finely and excessively densely punctate and dull ; antennae scarcely more than one-half as long as the body, very slender. Prothorax similar in form to tliat of the male, but with the surface extremely densely punctate, and with- out trace of median impunctate line, the punctures scarcely smaller than in the male and very much larger than those of the head. Elytra scarcely more than twice as long as wide, at base rather more than one-third wider than the prothorax, the humeri distinctly rounded but much more prominent than in the male ; sides almost parallel, feebly convergent toward apex, the apical truncation as in the male ; disk very coarsely, deeply, densely punctate, the punctures becoming much finer toward apex, coarser toward base than those of the male. Length 7.8-9.0 mm. ; width 2.5-3.0 mm. Michigan (Marquette). Mr. Schwarz. This species is allied to satiguinea Lee, but differs in the much stouter male antennae and in the radically different truncation of the elytral apices ; the latter in sanguinea is rather broad, scarcely at all oblique, and is almost i)erfectly straight, the angles being blunt; in lacustris it is very much narrower, oblique, deeply sinuate and with the angles, especially the exterior, very acute and prominent,. 44 ColeopteroJogical Notices, III. nearly as in canadensis. The sexual differences throughout the body are extremely and unusually marked, and in the series before me, the females are decidedly smaller than the males. IPOCHUS Lee. The chief differences between this genus and Moneilema, apart from the tribal characters relating to the support of the labrum and size of the body, are the shorter and broader front, presence of long tactile flying hairs on the body legs and antennas, and the great divergence in form of the sexes. The last of these is one of the most remarkable of the generic peculiarities of Ipochus, the male being slender, strongly convex, with oval el\'tra, subglobular pro- thorax and constricted neck, and the female more robust, subparallel. the prothorax transversely subquadrate and the neck scarcely at all constricted, the head l)eing more deeply inserted. It will be observed therefore that the sexual differences are directly the reverse of those of Moneilema, in which, when these are at all pronounced, the male is more robust parallel and compact than the female, and with a larger prothorax. The following species are indicated b}^ the material at hand : — Elytra witli three transverse, irrregular and more or less narrow fasciae, the tirst near the base, the second at apical third (viewed vertically), and the third on the apical declivity, extending semi-circularly from the side margins, crossing the suture midway between the second band and the apex ; recumbent pubescence rather sj^arse ; pronotum very coarsely, deeply and not closely punctate, with two pairs of small discal pubescent spots. Elytra broadly, deeply sinuate at apex when viewed along the longitudinal axis of the body. Length 4.5 mm. ; width 2.0 mm. (San Diego.) ..fasciatUS Lee. Elytra with two more or less narrow transverse fascite, which are irregular and zigzag in form, the first at the base, the second at apical fourth (viewed vertically) ; in addition a small elongate-oval sutural spot near the apex on the declivity. Body sparsely pubescent, the pronotal punc- tures coarse, moderately close, distinct, the integuments shining. Head finely, sparsely punctate ; antennae about as long as the body, the outer joints feebly annulated at base. Prothorax one-fourth wider than long, the sides rounded, more convergent toward base, the latter much narrower than the aj^ex ; discal pubescent spots evanescent, the fine pubescence very sjjarse, short and inconspicuous. Elytra one-third longer than wide, in the middle one-third wider than the prothorax; sides rounded, tlie apical portion of the disk perpendicular and deep ; apex not appreciably emarginate when viewed longitudinally. Abdomen sparsely pubescent. Coleopterological Notices, III. 45 Length 7.0 mni. ; widtli 3.4 mm. (female) ; in the male the length is 5.0-7.0 mm. ; width 1.6-2.2 mm. (Los Angeles. )....subiiitidlis n. sp. Elytra each with two transverse fasciae, the first subbasal, the second very wide, with uneven margins, extending from the middle to the apex (viewed vertically) and with a prolongation posteriorly along the suture. Body robust, compact, the head and pronotum extremely densely pubes- cent, the vestiture comjiletely concealing the surface lustre and punctua- tion, the elytra slightly shining and less densely pubescent. Head rather strongly, somewhat closely punctate ; antennae nearly as long as the body, the outer joints scarcely annulate at base. Prothorax fully one-third wider than long, the base much narrower than the apex ; disk with two pairs of small discal pubescent spots, and another which is median and more posterior. Elytra two-flfths longer than wide, behind the middle but little wider than the prothorax ; apex broadly, feebly, subangularly emargi- nate (viewed longitudinally) ; sides Yury feebly arcuate ; disk finely, very sparsely punctate. Abdomen densely pubescent. Length 7.. 'J mm. ; width 3.2 mm. (San Diego.) pubescens n. sp. The species above identified as fasciatus agrees in every particu- lar with the type in the LeConte cabinet. All the characters of the above diag-noses are taken from the female, except when otherwise noted. Two males which I obtained from the blossoming branches of the Monterey pine, near the town of that name, seem to indicate another species, which the absence of the female prevents me from describing at present. Another specimen from San Diego, resembles suhnitidus, but is still more shining and sparsely pubescent, and has a large impunctate median area of the pronotum, which is finely and deeply canaliculate ; it is probable also that this is a distinct species, but more confirmatory material is necessary. MONEILEMA Say. The following species belongs to the subgenus Collapter^^x as defined by Dr. Horn : — M. spinicollis n. sp. — Moderately robust and convex, the elytra sub- carinate at the sides toward base, black, rather strongly polished, glabrous. Head with a few fine punctures beneath the eyes and antennae, impunctate toward the middle, the front separated from the epistoma by a deep transverse impression ; antennae three-fourths as long as the body, with the fourth joint alone annulate at basal two-fifths ; scape very long and thick, with a few fine widely disjiersed punctures. Prothorax strongly transverse, from one-third to nearly one-half wider than long, the base and apex equal in width, feebly arcuate ; sides parallel, feebly arcuate, the spine long, acute, directed upward and backward ; disk evenly convex, with a more or less incomplete and very 46 Coleopterologieal Notices, IH. fine stria along tlie miclrlle, the punctures very fine and widely dispersed, but coarse and deep along tlie basal margin and on the flanks beneath the spine. Elytra oval, from two-thirds to once longer than wide, the sides arcuate but sometimes almost straight and parallel, scarcely wider than the prothorax in the male but distinctly so in the female, very coarsely and sparsely punctate in scarcely more than basal half. Posterior tarsi as in armata in form, but with the second joint densely spongy-pubescent throughout, except along a median line which becomes broad at base, the basal joint sometimes with a small spot of dense yellow spongy-pubescence at each apical angle. Length 23.0-29.0 mm. ; width 9.0-11.5 mm. Arizona. Four specimens from the Levette cabinet. This species dififers from gigas in its much shorter and more transverse prothorax and smaller size, and from arviafa in the much longer and thicker antcnnal scape, longer thoracic spines and in the more spongy pubescent second joint of the hind tarsi. It should be placed im- mediately after gigas in the catalogue. The ashy pubescence of the fourth antennal joint forms a narrow band extending from basal sixth or seventh of the length to about the middle. PSEIVOCERUS Lee. The two species contained in my cabinet may be recognized as follows : — Elytra each strongly tumid on the disk near the base ; body ferruginous, the elytra each with an oblique subinterrupted fascia at the middle and a broader transverse spot near apical third white, the portion between the two fascise blackish superiiotatlis Elytra but very feebly tumid near the base ; body piceous-black throughout, the elytra with a transverse interrupted fascia of white pubescence at apical third tristis In both of these species the scutellum is clothed with dense white pubescence. P. tristis n. sp. — Form nearly as in supcruotattiii, feebly shining ; pubes- cence rather sparse and inconspicuous. Head finely but deeply and very densely punctate ; antennae scarcely three-fourths as long as the body, cylin- drical, the third and fourth joints elongate and subequal, joints five to eleven shorter and becoming still shorter near the apex, the joints compactly joined. Prothorax slightly wider than long, strongly constricted near the base ; upex much wider than the base ; sides nearly parallel in apical two-thirds ; disk evenly convex, rather coarsely, deeply, extremely densely punctate. Elytra Coleople7'ologicaI Notices, III. 4V parallel, distinctly wider than the head and prothorax, and a little more than twice as long as wide ; humeri right and rather prominent ; apex evenly rounded ; disk coarsely punctate, the punctures not quite in mutual contact, and, between the fascia and extreme apex, becoming very sparse. Under surface finely, densely punctate throughout and finely, inconspicuously pubes- cent. Ze^s moderate ; tarsi short and stout. Length 4.5 mm, ; width 1.2 mm. New Mexico ? A single representative, the habitat of which is somewhat doubt- ful. The species is easily distinguishable from supernolatus by the characters given in the table. The basal tubercles of the elytra, so distinct in superyiotatus, are barely perceptible in tristU as broad and feeble swellings of the surface. MOIVOCHAMUS Serv. M. obtlisiis n. sp. — Stout, subparallel, moderately convex, brown throughout and marmorate nearly as in titiUntor. Head deeply angularly impressed between the antenufe ; front shining, sparsely pubescent, finely, sparsely and unevenly punctate ; antennae (male) two-thirds longer than the body, slender, not at all annulate, (female) but slightly longer than the body, distinctly annulate. Prothorax slightly wider than long, the lateral spines well developed ; disk shining, coarsely, confluently punctate, transversely rugulose anteriorly, with an oblong impunctate median area ; pubescence moderately conspicuous, feebly and minutely marmorate laterally, with two distant, discal spots before the middle. Scutellum glabrous, pubescent at base especially toward the sides. Ehjtra scarcely more than twice as long as wide, parallel in basal half in the male and basal two-thirds in the female, at base distinctly wider than the prothorax, the apices individually rounded, broadly so in the female, a little less broadly in the male ; disk very coarsely punctato-rugulose toward base, sparsely and more finely punctate thence to the apex. Abdomen densely pubescent, the pubescence whitish and finely, unevenly marmorate or nucleated. Legs rather short and moderately slender. Length 13.0-19.0 mm. ; width 4.7-6.8 mm. California. This species is not at all closely related to any other hitherto described. In general it resembles titillator, but is smaller, shorter and broader, with the apical angles of the elytra l)roadly rounded even in the males. In the recent table given by Dr. Horn it may be placed between scutellatus and confusor. The scutellum, which is pubescent only toward the sides of the base, will readily serve to distinguish it from any other of our species, and from oregonensis it may be known by its rounded elytral apices, scutellum and colora- tion. It is represented before me by a good series of six specimens collected near the northern boundary of the State. 48 Coleopterological Notices, III. LEIOPUS Serv. I., setipes n. sp. — Moderately robust, convex, piceo-testaceous, densely clothed witli dark luteous pubescence, devoid of fasciculate tufts of coarser hairs, and witli an anteriorly angulate white fascia behind the middle, also a very feebly defined paler oblique line on each elytron near the apex. Head extremely minutely, densely punctate when denuded ; eyes separated above by a distance which is scarcely more than one-half as great as in wilti; antennae slender, two-fifths longer than the body, nearly as in wilti. Prothorax one-half wider than long, four-fifths as wide as the elytra, rather finely and closely punctate, the pubescence very indefinitely variegated ; lateral spine short but not at all blunt, just behind the middle, nearly as in ivilti, but slightly more anterior in position. Elytra three-fourths longer than wide; sides nearly parallel in basal two-thirds, then oblique to the apex, each elytron narrowly and obliquely truncate ; disk coarsely, deeply punctate when denuded, each elytron with a large lateral blackish semi-denuded spot, and three costiform lines along which the pubescence is more prominent, the recumbent pubes- cence unusually long ; erect hairs short and very sparse. Under surface dark plumbeus, densely pubescent. Legs rather short and stout, throughout nearly as in wilti, but with long flying hairs on the tibiae, especially pronounced on the posterior. Length 7.0 mm. ; width 2.8 mm. Texas (El Paso). Mr. Dunn. This species in general appearance is intermediate between alpha and loilH, but is not closely related to any other form, the long flying hairs of the tibiae being a very unusual character in Leiopus. In the present arrangement of the species it may be placed just after jyunntatus. L/. niillieticiIS n. sp. — Ratlier robust and convex ; integuments rather pale rufo-testaceous, the pubescence short, luteo-cinereous, scarcely at all variegated on the prothorax, the elytra with very minute sparsely placed black fasciculate tufts, which are usually arranged in four or five rows on each, and, in addition, with an elongate blackish semi-denuded spot at the side, and an oblique black fasciculate and usually interrupted line near posterior third. Head extremely minutely, moderately densely punctate; eyes separated above as in pitnciatus ; antennae one-half longer than the body, annulate with black at the apex of each joint as usual. Prothorax rather short, three-fourths wider than long and four-fifths as wide as the elytra, evenly convex and pubescent, not distinctly punctate, the lateral spine very short and broad but not in the least rounded, situated just before basal third. Elytra four-fifths longer than wide, the sides subparallel in basal two thirds, then oblique to the apex, each elytron narrowly and obliquely sinuato-trun- cate ; disk coarsely, deeply punctate when denuded. Under surface very finely, densely, uniformly pubescent. Legs short, maculate, the femora strongly clavate ; tibise without long flying hairs ; tarsi short and robust. Length 4.5-6.5 mm. ; width 1.8-2.6 mm. Goleopterologioal Notices, III. 49 Texas; District of Columbia. A small, robust and convex species, with unusually short, even and pale pubescence, and bearing a striking resemblance to Lepto- stylus biustus. It is rather closely related to Leiopus crassulu.-^, from Lower California, but is well distinguished by its more elon- gate and convex form, longer and denser pubescence, and especially by the form of the elytral apices, which are here obliquely and strongly truncate, but evenly rounded in crassuhis. This species has been described by Dr. Horn (Tr. Am. Ent. Soc, VIII, p. 125), and somewhat doubtfully referred to L. crassidus, but I think that the form of the elytral apices will conclusively distinguish them. It is scarcel}^ possible to divide our species of Leiopus generically upon the presence or absence of fasciculate tufts on the elytra, and, as there is but little difference in the degree of separation of the middle coxte, the mesosternum being rather broad throughout, it seems probable that all of our species will have to be assigned to Eleothinus as recently defined by Mr. Bates, or, perhaps more justly, the genus Sternidius Lee. should be revived for these species, in which case Eleothinus would become synonymous. VALEIVrS n. gen. Body oblong, depressed, minutely, sparsely pubescent and with long erect sparsely jjlaced flying hairs. Head vertical ; front subqnadrate, transverse, finely carinate along the coriaceous support of the labrum ; mandibles small ; palpi slender, unequal, the terminal joints slender and gradually acuminate, second joint of the labial robust, the third oblique and much narrower ; men- tum small, transverse, very deeply inserted and inwardly oblique ; eyes deeply emarginate, moderately finely granulate; antennfe inserted at the sides within the ocular emarginations, widely distant at base, slender, minutely, rather densely pubescent, the first three or four joints with a single series of short, spinose setfe beneath, scape long, slender, cylindrical, without trace of apical cicatrix. Prothorax obliquely spinose at the sides behind. Elytra not cari- nate at the sides. Anterior coxse not appreciably angulated externally, the middle cavities distinctly open, narrowly separated. Legs slender ; femora feebly clavate ; tarsi short, robust, the basal joint of the posterior slightly longer than the next two combined ; claws divaricate, small. This genus belongs near Lepturges and is apparently still more closely allied to the Central American Phrissolaus Bates, differing from the latter in its much shorter antennae, depressed form, rounded elytral apices and more normal abdominal structure, the fifth seg- ment of the male being only as long as the two preceding together and obtusely sinuate at apex. 50 Coleopterological Notices, III. There is an element of uncertainty as to the proper position of Yalenus, however, owing to the fact that the only known represen- tative is a male, but if the female proves to have an elongated fifth segment, it can only be compared with Astynomus, and from this it departs widely in its spinose and not tuberculate prothorax. v. ilioriiatus n. sp. — Moderately robust, feebly sliining, dark rnfo- testaceous above, mncb paler beneath, the color of the integuments not at all concealed by the extremely minute, rather sparse and inconspicuous vesti- ture, the long flying hairs of the elytra rigid and setiform. Head extremely minutely, densely but feebly punctate ; antennfe about one-third longer than the body, slender, the scape thicker but not at all clavate, as long as the next two combined, joints three to eleven gradually decreasing in length. Pro- thorax fully one-half wider than long, distinctly wider than the head and two- thirds as wide as the elytra ; base and apex transverse, the former distinctly the narrower ; sides broadly arcuate anteriorly, obliquely and acutely spinose at basal third, disk very unevenly and sparsely punctate, almost impunctate toward the sides. Scutellum rather large, broadly rounded behind. Elijira parallel, the sides straight, three-fourths longer than M'ide, broadly rounded behind, each elytron narrowly rounded at apex ; disk coarsely and rather closely punctate toward base, the punctures becoming sparser and finer toward apex ; punctures bearing the flying hairs small and inconspicuous ; surface even. Under surface pruinose with dense, extremely minute pubescence. Length 9.0 mm. ;. width 3.3 mm. Texas (El Paso). Mr. G. W. Dunn. Resembles an unusually large robust Lepturges, but with much less conspicuous pubescence than in the species of that genus, and without trace of any kind of maculation. HYPERPLATYS Hald. Our species of this genus are closely allied among themselves, but may possibly be recognized by the following table: — Body black throughout ; antennre black ; femora red, black toward apex. feiuoralis Hald. Body paler, clothed above with cinereous pubescence, maculate with small black spots ; antennje in great part pale. Prothorax but feebly transverse, one-half wider than long ; femora red, the ajiices black Iligrella Hald. Prothorax strongly transverse, at least three-fourths wider than long.

Coleopferological Notices, III. 51 Elytral spots small, more or less distinctly arranged along three even lines on each elytron, the lines more or less pale ; antennre of the male much more than twice as long as the body. Elytra coai-sely punctate, the punctures distinct aspei'Sa Say. Elytra finely punctate, the punctures almost completely concealed by the vestiture ; elytral lines very indistinct. Body moderately robust, pale rufo-testaceous throughout, the pubescence short, very deiise, pale cinereous-white, the elytral spots small, sometimes with a larger more irregular discal blotch at apical third, the pronotura with four spots in an arcuate line, the two median larger. Head and antenuEe nearly as in aspersa. Prothorax acutely, obliquely spiculate at the sides at basal fourth or fifth. Elytra twice as long as wide, in form throughout nearly as in maculata. Legs pale testaceous throughout, the tarsi alone darker. Length 4.7-G.5 mm. ; width 1.8-2.4 mm. (California, Sta. Cruz Co.) califorilica n. sp. The species above identified as nigrella seems to be abundantly distinct from maculata in its much longer male antennas, and from aspersa in its more elongate prothorax and more finely and sparsely punctate elytra, the sides of the latter being much more convergent from base to apex in the male, and with more prominent and less rounded humeri. In aspersa the three discal vittae of the elytra are nearly always very distinct and generally conspicuous, and by this characteristic it can be separated at once from the other species. Anisopodus White is possibly synonymous with Hyperplatys, at least the elongation of the posterior legs appears to be so gradual as to cause great confusion in attempting to limit the former genus. SPAI.ACOPSIS Newm. The species of this remarkal)le genus which have been discovered within our faunal limits, may be distinguished as follows : — Scutellum small, not longer than wide, rounded or feebly bilobed behind; elytra parallel stolata Scutellum triangular, not longer than wide. Elytra subparallel, with even rows of coarse and distinct punctures, with- out denuded spots ; scutellum wider than long ; size small Sllffusa Elytra infiated behind, with the punctuation close and almost confused, and with large uneven semi-denuded spots ; scutellum small, equilatero- triangular ; size larger texaiia S. texana n. sp. — Slender, cylindrical, distinctly inflated behind the middle of the elytra, densely clothed throughout with rather long recumbent luteo-cinereous pubescence, and with extremely short erect sparse setffi. Head 52 Coleopterological Notices, III. two-tliirds longer than wide, nearly as in siiffusa, the antennae a little shorter than the body, the scape one-half longer than the prothorax. Prothorax two- fiftlis longer than wide, equal in length to the head, cylindrical, the sides parallel ; surface densely and evenly pubescent, with a small narrow denuded median area. Elytra between four and five times as long as the prothorax, equal in width to the latter toward base but two-thirds wider behind the middle, then narrowed to the apex which is deeply, triangularly emarginate, the processes acute but blunt at apex and feebly everted ; disk coarsely, deeply, rather closely punctate, the punctures and pubescence having a vaguely lineate disposition, with large uneven semi-denuded blotches. Length 9.7 mm. ; width 1.3 mm. Texas. Differs greatly from the Mexican protensa and variegata in its small equilateral scutellum, and from suffvsa and phaMasma in its larger size and from the latter in addition in the absence of long curved rigid setiB. From the eastern stolafa and Cuban grandis it differs in its convex and not flattened elytral disk, and from the Cu))an filum in its non-sulcate elytra. The semi-denuded blotches of the elytra are sparsely scattered, but slightly darker in color, and are broad and very irregular and not linear as in stolata. TENEBRIONID.E. STIBIA Horn. The following species belongs near ovipennis, but differs greatly in the structure of the e\^cs : — S. inaritima n. sp. — Moderately robust, strongly convex, polished, brownish-testaceous in color, glabrous. Head finely, rather densely punctate and finely, longitudinally subrugulose ; antennre two-fifths as long as the body, very slender, feebly clavate at apex, third joint one-half longer than the fourth, the latter equal in length to the second ; eyes moderate, feebly and evenly convex. Prothorax two-thirds wider than long, the base and apex equal, the former feebly arcuate, the latter correspondingly emarginate ; sides parallel, evenly and distinctly arcuate ; apical angles acute but not produced ; disk evenly convex, deeply, moderately coarsely punctate, the punctures tend- ing to coalesce longitudinally toward the sides, sparser toward the middle.

Abdomen minutely, extremely sparsely punctate, the metasternum very coarsely, rather closely so, the \ivo- sternum rather coarsely and very densely. Legs slender. Length 3.3-3.7 mm.; width 1.6— 1.9 mm. Goleopterological Notices, III. 53 California (San Diego Co.). Dr. F. E. Blaisdell. A single pair taken on the sea-beach at Coronado. In ovijtennis the color is black, the size larger, the form nuich more robust, the third antenna! joint longer, the eyes smaller and very much more convex and prominent, especially behind, and the elytral punctures larger and stronger. EPITRAGUS Latr.

Prothorax two-fifths wider than long, the sides moderately narrowed from base to apex, feebly arcuate, the apex broadly emarginate, angles right, narrowly rounded and not at all prominent ; base broadly, strongly bisinuate ; disk evenly convex, feebly bi- impressed at base, rather coarsely, moderately densely iiunctured laterally, the punctures becoming finer and sparser toward the middle, with a narrow impunctate median line. Elijtra two-thirds longer than wide, in the middle one-third wider than the prothorax, at the broadly rounded humeri slightly wider than the thoracic base ; sides feebly arcuate, oblique behind, the apex narrowly rounded ; disk finely, sparsely punctate, with irregular longitudinal impunctate areas toward the suture, the punctures becoming dense laterally and especially coarse, dense and rugulose near the margins toward apex, the surface longitudinally swollen near the suture toward apex. Under surface finely, rather sparsely punctate and distinctly pubescent. Mesosternum deeply excavated. Length 12.0 mm. ; width .5.2 mm. Arizona. A single specimen from the Levette cabinet, which is probably a male. The type appears to be analogous in general form to the males of those species having the pronotum simple in both sexes, and for the present it may be placed near jn-uinoaus, being readily distinguishable b}'' its robust form, bright metallic subttneous lustre and long conspicuous white pubescence. The species of Epitragus within our boundaries may be identified as follows : — Sides of the front angialate and reflexed ; prothorax much narrower than the elytra, the humeri broadly exposed SUllllietallicilS Sides of the front not prominent or angulate ; median lobe large, rounded. Pronotum simple in the male, more or less bicarinate in the middle toward apex in the female. 54 Coleopferological Notices, III.

Elytra rugulose ; j^rothorax rather strongly transverse. plumbeus Elytra smooth, not at all rugulose, except occasionally toward the sides. Elytra very densely punctate throughout ; prothorax but very slightly wider than long OTalis Elytra sparsely punctate, at least toward the suture. Elytra nearly glabrous, each puncture with an extremely minute seta pi'lliliosus Elytra conspicuously pubescent, the pubescence white. vestitus Although by the characters given, ovalis is brought very near to plumbeus, it is really quite distinct in general appearance from this and all the other species, being unusually short, oval and convex. The material before me seems to indicate several closely allied species in the neighborhood of canaliculatus, one male, especially, has the punctuation very sparse throughout, with the apical angles of the prothorax not at all everted. EPITRAGODES Cas. This name was proposed (Ann. N. Y. Acad., Y, p. 365) for the species known as Epiti-agus tomenlosus Lee, the principal charac- ters distinguishing it from Epitragus being the unexcavated meso- sternum and the more or less seriate arrangement of the elytral punctures. I have recently received another species, the two being easily known by the following characters : — Body rather densely pubescent, the pubescence unevenly marmorate. tonieiitosus Body glabrous, each puncture bearing an infinitesimal seta entirely concealed within it jikliclli Coleopter'ological Notices, III. 55 E. jiiliclli n. sji. — Almost evenly elliptical, convex, black throngliout with slight greenisli-uietallic lustre. Head rather coarsely, densely punctate throughout, the punctures becoming but slightly sparser toward the middle of the vertex ; front trilobed, the median lobe longest, broadly rounded ; supra- orbital ridge obsolete but slightly evident in front of the upper margin; antennae about as long as the prothorax, joints six to nine serrate internally. Prothorax one-third wider than long, the apex subtruncate, scarcely more than three-fifths as wide as the base, the latter broadly, strongly lobed in the middle, feebly sinuate thence to the basal angles, which are right ; apical angles obtuse but not at all rounded ; sides broadly arcuate and subparallel in basal half, becoming more arcuate and convergent thence to the apex ; disk not at all impressed, rather coarsely, very densely punctate, the punctures nearly in contact but distinct throughout in contour, becoming slightly sparser toward the middle, without an irapunctate median line.

The hind wings are as long as the elytra. Two specimens, prob- ably from the neighborhood of Galveston, one of which I owe to the kindness of my friend Mr. Wilhelm Jiilich. ANEPSIUS Lee. The two species known to me may be separated as follows: — Antennae much longer than the head ; elytral punctures arranged in regular approximate series throughout delicatlllllS Antennae very short, not longer than the head ; elyti-al punctures arranged serially only towards the sides moiltanus A. niOIltailllS n. sp. — Robust, parallel, convex, polished, black through- out, the legs and antennae dark rufo-testaceous ; integuments glabrous, each puncture bearing an extremely minute seta. Head feebly convex, transverse, not very coarsely but strongly and rather densely punctate, the punctures rough or subgranulose ; eyes completely divided ; antennae moderately robust and compressed, compact, the last joint not as long as wide and slightly narrower than the tenth.

This species differs from delicatulus in its shorter, broader form, coarser punctures and radically different punctuation of the elytra. Several specimens. EUSATTIJS Lee. The following form is not at all closely allied to any other thus far described, but may be placed just after robustus in our lists: — E. 'WelJSteri n. sp. — Form and size nearly corresponding with the larger specimens of reticulatus, black tliroughout, rather strongly convex, glabrous, the pronotum dull and coarsely sericeous, the elytra somewhat shining. Head coarsely, densely punctate, the punctures strongly coalescent and rugulose behind ; antennte subequal in length to the prothorax, the third joint equal in length to the next two together. Prothorax nearly two and one-half times as wide as the median length, the apex deeply emarginate, two-fifths as wide as the base, the latter transverse, broadly sinuate toward the basal angles, which are acute and slightly prominent posteriorly ; sides strongly convergent anteriorly and very feebly arcuate from basal third, thence to the base nearly parallel and more arcuate ; apical angles anteriorly produced far beyond the eyes, but with the apex rounded ; disk strongly convex, very broadly expla- nate and reflexed at the sides, coarsely, deeply, extremely densely punctate throughout, the punctures longitudinally confluent, and, on the reflexed lateral parts, becoming coarsely rugulose and confusedly confluent.

I take pleasure in dedicating this species, perhaps the most inter- esting- of the novelties contained in the Levette cabinet, to Mr. F. M. Webster, in partial recognition of many favors rendered by him in connection with the transfer of the cabinet mentioned. ELEODES Escli. The following species, represented by a series of eleven specimens from the Levette cabinet, is not closely allied to any other, but may be placed for the present near humeralis : — E. rileyi n. sp. — Rather robust and convex, somewhat strongly shining, intense black throughout. Head coarsely, rather closely punctate ; antennae subequal in length to the head and prothorax, the third joint thi'ee times as long as wide and rather longer than the next two combined, the outer joints but moderately robust. Prothorax from one-fourth to three-fifths wider than long, the apex broadly, feebly emarginate, distinctly narrower than the base, the latter transverse, generally very broadly, feebly sinuate toward the middle ; apical angles obtuse but not at all rounded, basal slightly obtuse, not much rounded and rather prominent ; sides strongly arcuate at apical third, thence strongly convergent and nearly straight to the apex, distinctly sinuate before the base ; disk rather coarsely, deeply punctate, densely so toward the sides, sparsely and unevenly, with large impunctate patches toward the middle. Elytra two and one-half times longer than the prothorax, and, in the middle, from one-fifth to nearly one-half wider than the latter ; sides evenly arcuate ; humeri narrowly rounded, slightly prominent and usually distinctly exposed ; apex narrowly rounded ; disk almost vertical behind, rather coarsely, feebly and subasperately punctate, sometimes with very feebly impressed distant lines, the punctures rather sparse, not much denser laterally, confusedly disposed but often having a feeble lineal arrangement. Prosternum not at all produced. Anterior tibial spurs extremely unequal, the anterior robust, long, subparallel and truncate at apex, the posterior very small, acute, the larger spur still more pronounced, broader and more truncate in the female. Length 12.0-15.0 mm. ; width 5.2-7.2 mm, Arizona. The anterior femora are completely unarmed in both sexes, and the relative proportion in the length of the anterior tibial spurs is nearly independent of sex, but both spurs are longer, and the ante- rior much wider, more broadly truncate and more parallel in the female than in the male. From humeralis the present species differs in its smaller size, Annals N. Y. Acad.

Femora all slender and completely unarmed ; spurs of the anterior tibi?e very unequal, the anterior slender, acutely pointed and moderate in size ; posterior tarsi slightly com- pressed, nearly three-fourths as long as the tibia'. Prosternura slightly pro- longed but not at all rellexed, the apex vertical. Length 18.0 mm.; width 6.7 mm. Arizona. This species, which is reiiresented before me by a single speci- men, apparently a male, belongs near longiroUis, but differs in its flatter, rather shorter jirothorax, less rounded on the sides, in its shorter, broader elytra, broadly and rather strongly emarginate at base and having widely distant rows of punctures, and in its shorter, stouter and much more clavate antenna?. E. COllipOsitllS n. sp. — Moderately robust, convex, intense black throughout, the pronotum dull and strongly alutaceous ; elytra shining, very feebly alutaceous, glabrous. Head densely dull, finely, rather sparsely punc- tate ; antenniB rather long and stout, fully as long as the head and prothorax, third joint between three and four times as long as wide, outer joints slightly broader, the ninth and tenth somewhat transversely oval.

Elytra about two and two- thirds times as long as the prothorax, and, in tlie middltj, one-half wider than the latter, about twice as long as wide ; sides broadly arcuate ; humeri not at all exposed; apex acutely angnlate; disk strongly declivous behind, deeply sulcate, the ridges strongly convex and shining, each with a single rather uneven series of small, moderately distant punctures, the intervals as wide as the ridges, deep, opaque, each with a single series of rather small, close-set, asperate punctures. Legs slender, the femora shining, rather finely but strongly punctate, the ant(!rior alone with a strong acute tooth near tlie apex ; tibise strongly rugose except toward base, the spurs of the anterior small, acute and nearly equal. Presternum with the apex slightly retlexed, acute and tuberculiform. Length 16.0 mm, ; width 0.6 mm. Texas. A single specimen from the Levette cabinet. This species has but little affinity with any other thus far described, the prothorax being nearly similar to that of (jentilis and the elytra deeply sulcate, as in the typical hinpilabriH; for the present it may be placed just after the latter in our lists. £UJLABIS Esch. The species of this genus may be distinguished as follows: — Pronotum bicarinate ; body glabrous Ibicai'iiiata Pronotum not at all carinate.

The last of these was placed in a separate genus by LeConte, and possibly Epantius should be regarded as valid, or at least a good subgenus. E. laticornis n. sp. — Sloderately robust, subparallel, somewhat de- pressed, glabrous, black to piceous-black ; legs paler, rufo-i^iceous ; antennie black ; integuments dull. Head coarsely, densely punctate, the punctures finer, less crowded and more asperate anteriorly ; epistoma transversely trun- cate ; eyes short and transverse but only one-half divided ; antennae unusually long, almost attaining the base of the prothorax, extremely stout, the outer joints strongly transverse and compressed, Prothorax one-fifth to one-fourth wider than long, the apex transversely truncate, rather distinctly wider than the base, the latter extremely feebly arcuate ; apical angles very obtuse, dis- tinctly rounded, basal widely obtuse but not rounded and generally minutely prominent ; sides broadly, evenly arcuate, more convergent and straighter toward base ; disk widest before the middle, evenly, very feebly convex, coarsely, deeply, extremely densely punctate, the punctures having much less tendency to longitudinal coalescence than in crassicornis. Elytra one-half longer than wide, oblong-oval, about twice as long as the prothorax, and, in the middle, about one- fourth wider than the latter, abruptly, obtusely rounded at apex ; sides broadly arcuate ; humeri narrowly rounded, somewhat tuber- culiform and prominent and distinctly exposed ; base broadly, feebly emargi- nate, the basal margin unevenly tumid ; disk broadly flat above, the costse strongly marked ; intervals each with a single row of coarse deep circular punctures.

Legs very stout and moderately long, the hind femora much longer than the intermediate ; anterior tibiae slightly arcuate, stout. Length 9.2-10.0 mm. ; width 3.8-4.2 mm. California (San Diego). One of the two specimens before me formed part of the Levette cabinet, the other was kindly communicated by my friend Dr. F. E. Blaisdell, and was collected at Poway. This species is quite distinct from any other thus far known ; it is nearly as large as grossa, but has less inflated elytra. It may be readily distinguished from crassicornis by its more robust and especially much longer antennte, much larger size, more depressed form, coarser punctuation and scarcely at all longitudinally rugulose sculpture of the pronotum. CIBDELIS Mann. C. laevigata n. sp. — Moderately robust and convex, intense black throughout, glabrous. Head rather coarsely, densely punctate behind, much Coleopterological Notices, III. 61 more finely so on tlie epistoma ; sides broadly reflexed before the eyes ; antennae rather short and slender, about as long as the prothorax, rufescent at base, the third joint distinctly shorter than the next two together. Pro- thorax nearly twice as wide as the head, two-fifths wider than long, the apex and base subequal, the former truncate, feebly sinuate laterally, the latter broadly, feebly arcuate ; sides broadly, evenly arcuate, becoming oblique and straight near the basal angles, which are very obtuse but not rounded ; apical angles slightly obtuse and narrowly rounded ; disk feebly alutaceous in lustre, evenly convex, rather finely, sparsely punctate throughout, the punctures becoming almost obliterated near the thick marginal bead.

Legs short and slender. Length 13.0 mm. ; width 5.6 mm. California (Sta. Barbara). Mr. G. W. Dunn. This species differs from blaschkei in its shorter, broader form, smooth surface, finely, rather sparsely punctate prothorax with the sides behind oblique and straight and not at all sinuate before the broadly obtuse basal angles, and in the much smoother and less tuberculate elytra. In general appearance it is altogether distinct from either blaschkei or hachei. A single specimen. AL^PIIUS Horn. ^. macilentlis n. sp. — Elongate-oval, moderately convex, pale luteo- flavate throughout, strongly shining, the head and pronotum very slightly alutaceous ; body nearly glabrous, each puncture of the elytra bearing a short pale recumbent seta. Head rather coarsely punctate, the punctures shallow, strongly and polygonally crowded forming a reticulation of raised lines ; eyes large, angulate antero-internally ; front deeply impressed at each side in front of the eyes ; antennae slender, cylindrical, filiform, a little longer than the head and prothorax, the outer joints not thicker but gradually much shorter, third very long and slender, though scarcely as long as the next two together. Prothorax but very slightly wider than long, the apex transversely truncate, nearly three-fourths as wide as the base, the latter transverse, very broadly, feebly bisinuate ; basal angles right, not rounded, the apical very obtuse and rather blunt ; sides broadly, feebly, almost evenly arcuate ; disk scarcely as wide at base as just behind the middle, feebly convex, broadly, feebly impressed along the middle, feel)ly, rather widely reflexo-explanate laterally, especially toward base, very feebly, subcoalescently punctate and 62 Coleopterological Notices, III. minutely subrngulose.

Abdomen finely, sparsely punctate. Leg/i moderate in length, slender. Length 5.0-6.4 mm. ; width 1.7-2.2 mm. Arizona; New Mexico. Distinguishable from pallidus by its much smaller size and more slender form, more quadrate prothorax, still paler coloration and more shining surface lustre. Apparently not rare. IDIOBATES n. gen. This name is proposed for Tenehrio castaneus Knoch, an anoma- lous form hitherto associated with the normal members of Tenebrio, but manifestly distinct b}^ reason of its completely divided eyes and abdominal structure, only the penultimate segment of the latter being provided with a visible coriaceous hind margin. I would suggest that it be placed in the Blapstini near Mecysmus. The generic value of caManeus was long ago recognized by Bates, and later by LeConte, but I am not aware that it has ever been given a distinctive name. It certainly constitutes as good a connective bond, between the Blapstini by way of Mecysmus and the other Tenebrionini through Tenebrio, as could well be found, the undilated anterior tarsi being a matter of no material import- ance in this connection. In the table of the tribe Tenebrionini given on page .393, Vol. Y of these Annals, the genus Calcar, together with one or two other exotic genera, must constitute a group distinct from the Tenebriones by reason of the very exceptional abdominal structure, the coria- ceous hind margins of both the third and fourth segments being completely invisible. This well-known fact was inadvertently over- looked in compiling the table alluded to. BLAPSTIXUS Latr. I have recently, by way of experiment, dissected a series of eight specimens of a form very near 7'iijipes, probably a variety or race of that species, and have found a singular and altogether unexpected Goleopterological Notices, III. 63 constancy in the form and size of the I'udimentary hind wing, the extreme variation not amounting to more than one-fifth of the average length, the latter being a little more than one-half the total length of the elytra. This is not put forward as proof of any general rule, but simply as an isolated fact in a field very little explored and still less understood. It seems extremely difficult to account for this constancy by the theory of natural selection, and, as it is impossible to doubt the ever-acting reality of the principle in question, we can only infer that rudimentary organs are not necessarily inordinately variable, and, when comparatively constant, that the standard is maintained by the action of other laws less easily appreciated. Darwin, in his "Natural Selection," dwells but briefly upon this question, but gives as one instance of variability in rudimentary organs, the wings of a certain beetle which may be either fully developed or more or less rudimentary. Other authors have also cited examples of a corresponding nature. I think, however, that there is more or less doubt to be attached to this entire category of observations, due to a lack of knowledge of the physical conditions under which the various specimens may have existed. It would for example be manifestly repugnant to the fundamental idea of natural selection to imagine individuals of the same species, with fully developed and rudimentary wings living together on the same bush^— except in cases of sexual dimorphism, which constitute a wholly different branch of the subject, — for this very principle would tend to eliminate those individuals which were least able to maintain themselves, and we cannot assume that perfectl}^ and partially developed wings constitute conditions equally fitting the species to maintain itself against a great variety of external influ- ences. The only conceivable circumstances under which individuals of a wingless species may, under the same conditions, also be found with more or less developed wings, are due to occasional reversion to the conditions characterizing the primitive stock from which the species may have been derived. If the species has been differentiated for a comparatively jrreat length of time, which may perhaps be judged of approximately by its degree of departure from related winged species, this reversion will surely be quite exceptional. Wingless species occurring on oceanic islands are frequently said to be identical with continental fuUv winijed forms, but it seems as 64 Coleopterological Notices, III. though the mere fact that one form is winpfed and the other wing- less ought to be sufficient ground for specific isolation, especially as it is highly probable that the more or less extended time necessary to bring the winged continental form to the wingless insular condi- tion, will generally be sufficient to develop other specific difTereuces At all events the wingless island form must always be considered an incipient species or variety, for this kind of isolation has been one of the most potent factors in the differentiation of species as we now understand them.

The following species bears but little external resemblance to elongata, but as the prothorax is strongly fimbriate, the body appa- rently apterous, and the anterior tibisB slender, it must either be placed here or in a new genus : — C lacilliata n. sp. — Moderately slender, obloiig-suboval, densely punc- tate anteriorly but rather shining ; body black throughout, the legs rufous, the antennae dark piceo-rufous ; pubescence rather dense, moderately long, nearly as in Blapstinus, very coarse, rigid, semi-erect and black, not very conspicuous. Head short and broad, broadly, feebly sinuate at ajjex, rather coarsely, very densely and deeply punctate ; eyes moderately large, the upper lobe elliptical ; antennre long, about as long as the head and prothorax, stout, clothed throughout with long stiff black setse, the outer joints gradually, feebly incrassate and distinctly transverse, the eleventh narrower than the tenth, the third long, equalling the next two combined. Prothorax about one-third wider than long, the apex as wide as the base, transversely truncate, the base broadly arcuate, not appreciably sinuate toward the basal angles which are obtuse but not rounded ; apical slightly obtuse, not rounded ; sides broadly, almost evenly arcuate ; disk widest near the middle, evenly convex, rather coarsely, very deeply and extremely densely punctate throughout, the side margins with a dense fringe of long erect stiff setse. Scutellum triangular, entering the disk of the elytra, densely punctate. Elijtra about two and one- half times as long as the prothorax, and, in the middle, nearly oue-fourth wider than the latter, fully three-fourths longer than wide, obtusely para- bolic at apex ; sides parallel, very feebly arcuate ; humeri slightly exposed at base ; disk with rather coarse, feebly impressed series of somewhat coarse, deep, moderately close-set punctures, the intervals feebly convex, shining, extremely minutely, rather sparsely and confusedly punctate. Abdomen rather finely, but deeply and densely punctate, broadly, deeply impressed in the middle in the male. Legs rather slender, the hind tarsi with the basal joint subequal to the next two and very much shorter than the last. Length 4.G-5.0 mm.; width 1.8-2.1 mm. Coleopterological Notices, III. 65 Arizona (Tucson). Mr. H. F. Wickham. This exceedingly interesting- and aberrant species is easily recog- nizable by its rather long- antennie, conspicuous pronotal fringe and coarse black vestiture ; it will probably have to be ultimately sepa- rated from elongata as a distinct genus. PALEMBUS u. gen. I have applied this name to a small species, having very nearly the antennal structure of Oplocephala Lap. {= Evoplns Lee), and apparently allied to that genus, but differing in its narrower, more depressed form, non-tuberculate head, large coarsely faceted eyes, longer hind tarsi and entire epipleurse ; its general characters are as follows : — Body parallel, rather strongly convex. Head rather short and broad, the eyes large, more prominent than the sides before them ; antenn;« short, the last seven joints short and transverse, forming a long loose parallel club ; maxillary paljDi rather slender, the last joint elongate-oval, about as long as the preceding two together, the apex obliquely and narrowly truncate ; mentura obtrapezoidal ; ligula large, corneous, the connate paraglossfe large, broadly rounded. Prothorax transverse, the prosternum moderately wide between the coxae. Elytra striate ; epipleurse narrow, entire, flat. Legs ratlier slender, the anterior tibiae not dilated ; posterior tarsi long, but slightly shorter than the tibise, the basal joint equal to the last and as long as the second and third together, the third one-half longer than wide. In the type specimen the structure of the middle coxal cavities cannot be clearly discerned. P. ocularis n. sp. — Oblong-elongate, convex, pale rufo-testaceons throughout, shining, glabrous. Head evenly, feebly convex, finely, moder- ately densely punctate behind, the ei)istorna rather large, abruptly deplanate, feebly convex and very minutely punctate, the sides strongly convergent, the apex broadly truncate, the surface feebly impi'essed just before each eye ; eyes large, sej^arated above by scarcely their own width ; antennse one-third longer than the head, stout, compressed, the third joint a little longer than the fourth and one-half longer than the second. Prothorax four-fifths wider than long, the apex and base equal, the former broadly, feebly, evenly arcuate, almost truncate, the latter arcuate in the middle, oblique thence to the basal angles which are obtuse and blunt, apical rounded ; sides feebly arcuate behind, nearly straight anteriorly; disk slightly widest near basal third, evenly, transversely convex, distantly and feebly biimpressed at base, very finely, not densely punctate. Scutellum slightly wider than long, ogival. Elytra between three and four times as long as the prothorax, equal in width to the latter, fully twice as long as wide, parallel, obtusely rounded behind, 66 Coleopterological Notices, III. finely striate, the striae feebly but distinctly impressed, finely punctate, the intervals minutely, sparsely and confusedly punctured. Abdomen finely, not very densely punctate. Length 3.8 mm. ; width 1.3 mm. Florida. I owe the above-described specimen to the kindness of Mr. W. Jiilich, in whose cabinet there is a considerable series, di.spla^^ing scarcely any variation. RUES n. gen. This name is proposed for a distinct genus belonging near Hege- mona Cast., and represented by the species recently described by me under the name Helops ompennis (Ann. N. Y. Acad., Y, p. 48t). It resembles Hegemona in the unusually wide mesosternum, nearly flat between the coxaj, and in the exceedingly short meta- sternum, but differs in the wider elytra, extremely broad epipleurte and very short slender legs. HELOPS Fab. Both of the following species are related to bachei, and should immediately follow that species in our lists : — H. 'blaisdelli n. sp. — Oblong-oval, rather strongly convex, piceous- black, the elytra castaneous ; antennse and legs throughout rufo-testaceous ; integuments glabrous and strongly shining. Head feebly convex, rather coarsely, deej^ly, moderately densely punctate, the punctures longitudinally coalescent, forming long furrows and rugfe ; eyes prominent and convex ; antennse slender, filiform, nearly one-half as long as the body, joints four to ten elongate, evenly obconical, subequal, eleventh a little longer, third much longer. Prothorax transverse, one-half wider than long and four-fifths wider than the head ; base and apex subequal and both transversely truncate ; sides strongly and almost evenly arcuate ; apical angles broadly obtuse and nar- rowly rounded, basal very obtuse but scarcely rounded ; marginal bead very fine and feebly developed throughout the length ; disk very much wider at basal third than at base, evenly convex, somewhat coarsely, deeply, rather densely and unevenly punctate thi-oughout, the punctures but slightly sparser toward the middle, toward the sides more or less longitudinally coalescent in twos or threes. Scutellum broadly ogival. Elijtra two and one-half times as long as the prothorax and not in the least wider than the latter in any part, four-fifths longer than wide ; sides parallel and nearly straight ; apex obtusely ogival ; humeri rather broadly exposed at base, slightly obtuse, narrowly rounded ; disk rather finely striate, the strise entire, not impressed but abruptly grooved, the punctures elongate, moderate but uneven in size and mutual separation ; intervals flat, feebly and confusedly undulated, finely, not Coleopferological Notices, III. 67 very densely punctate, laterally toward the apex with small, distant, feebly elevated tubercles in single series on each. Abdomen finely, somewhat densely punctate ; metasternum but slightly shorter than the first ventral segment ; mesosternum long and depressed in front, rather narrowly separating the coxse, feebly declivous and slightly impressed before the coxre, the process be- coming horizontal behind ; prosternal process not at all prominent posteriorly. Legs moderately long, the tibiae rather strongly enlarged from base to apex, the anterior tarsi rather broadly dilated in the male, posterior short with the basal joint equal to the next two and much shorter than the last. Length 8.0-9.0 mm. ; width 3.2-3.3 mm. California (San Diego). Dr. F. E. Blaisddl. The two specimens before me are both males, and have the intro- mittent organ rather broad throughout, abruptly and sharply acumi- nate at apex, and with the upper surfiice deeply and longitudinally excavated, the excavation extending almost to the apex ; in bachei it is finely but less abruptly acuminate, and the upper surface is finely, longitudinally subcarinate near the apex, the excavation being very feeble and much less apical. The form of blaisdelli is considerably shorter and the prothorax is very much more trans- verse. H. discipilla n. sp. — Evenly elongate-oval, strongly convex, glabrous, moderately shining, the elytra alutaceous ; upper surface dark castaneous, beneath paler, rufcscent ; legs and antennae rufous. Head coarsely, not densely punctate, the punctures scarcely at all longitudinally confluent, slightly finer anteriorly ; eyes prominent ; antennse short, but slightly longer than the head and prothorax, joints four to eight increasing in length, rather slender, obconical, nine to eleven thence gradually shorter and more dilated, the last obliquely oval and not longer than the tenth, third one-half longer than the fourth. Prothorax nearly one-half wider than long, the apex rather distinctly narrower than the base, both subtruncate or extremely feebly arcu- ate ; sides strongly evenly arcuate ; apical angles broadly obtuse and slightly rounded, basal extremely obtuse and widely rounded ; marginal bead very fine but distinct throughout the length ; disk not very coarsely, rather densely punctate, the punctures sparser in the middle, with scarcely any tendency to coalesce longitudinally toward the sides. Scutellum broadly triangular, short, coarsely, rather densely punctate. Elytra oblong-oval, about three times as long as the prothorax, and, in the middle nearly one-third wider than the latter, twice as long as wide, gradually ogival behind ; sides parallel, broadly arcuate ; humeri obtuse, exposed at base ; disk with very fine, entire iinim- pressed series of fine unevenly spaced and generally more or less linear punc- tures, the intervals flat, minutely, sparsely, confusedly punctate, each with a single widely spaced series of very small tubercles, which are rather indistinct toward the suture. Abdomen finely, sparsely punctate ; sterna nearly as in blaisdelli. Legs rather long, very slender. Length 7.0 mm. ; width 2.9 mm. 68 Coleopterological Notices, III. California (probably near San Diego). Mr. W. Jiilich. The type is apparently a female, and the anterior tarsi are not dilated. It is easily distinguishable from both bachei and blaisdelli by the short antennte and broader elytra, and from the former, in addition, by its short transverse prothorax with fine marginal bead. H. cylilldriformis n. sp. — Narrow, strongly convex, subcylindrical, black throughout, shining and feebly alutaceous. Head scarcely as long as wide, broadly, evenly, feebly emarginate at apex, the surface rather finely and densely, very strongly punctate ; eyes rather more prominent than the feebly reflexed sides before them ; antennae slender about one-half as long as the body (male) or scarcely as long as the head and prothorax (female), third joint a little longer than the next two together, outer joints gradually and only slightly broader, the tenth about one-half longer than wide and a little shorter than the eleventh, the latter slightly longer in the male where it is twice as long as wide, obliquely acute at apex. Prothorax elongate, fully as long as wide, the apex broadly arcuate, a little narrower than the base, the latter subtruncate ; sides broadly arcuate at or just before the middle, feebly convergent and more feebly arcuate to the apex, broadly, distinctly sinuate before the basal angles which are right, not at all rounded and somewhat prominent ; disk evenly convex, finely, densely punctate, the punctures strong and always distinctly separated, but slightly less dense toward the middle where there is usually a narrow uneven impunctate line. Elytra twice as long as wide, not quite three times as long as the prothorax, and, in the middle, scarcely two-fifths wider than the latter ; sides parallel, broadly, feebly, evenly arcuate ; apex obtusely ogival ; humeri completly obsolete, the base exactly equal to the thoracic base ; disk with unimpressed series of small unevenly spaced but generally approximate and slightly elongate punctures, the intervals flat, very finely, irregularly, sparsely punctate. Abdomen very finely, rather sparsely punctate. Legs slender, the anterior tarsi very slightly dilated in the male. Length 9.0-14.0 mm. ; width 3.2-5.0 mm. New Mexico (Fort Wingate). Dr. Shufeldt. This species, which is represented by a series of eight specimens, is allied to difficilis, but differs in its more slender subcylindrical form, much more elongate prothorax with less blunt apical angles, narrower and more finely and sparsely punctate elytra and rather shorter antennae. H viridimicans Horn appears to be homologous with the Culjan rufipes, and to be more appropriately assignable to Nautes than to Helops, although it must be confessed that the difference between these genera has not been very satisfactorily expressed. H. montana Lee. is quite distinct from convexida in its broader, more oblong form, and in its longer and much stouter antennae and notably larger size. ColeopteroJogical Notices, III. 69 STRONGYLIUM Kirby. Two specimens of S. ati-um Champ., from the Levette cabinet and labeled "Arizona" are before me;. This species is quite aberrant in appearance and may be known at once by its large size, smooth but dull surface, rather coarse, very dense pronotal punctuation and fine unimpressed and feebly punctate elytral striie. CISTELID.E. There is probably no family, even of the Heteromera, where the differentiation of genera depends so little upon definite and constant modifications of special organs, and so greatly upon general habitus, as in the Cistelid*. There are, for exam])le, but few special char- acters relating to the palpi, tarsal lobes, eyes or antennce, which remain invarial)le throughout the limits of even those genera which, in the majority of species, are particularly distinguished by important developments or modifications of any one of the organs mentioned. We are therefore beset with numerous difficulties in our definition and limitation of the genera. In regard to the family considered in its entirety, however, the case is quite different, since there is no group of the Heteromera Avhich is so homogeneous within itself, or so clearly limited in extent. For, while closely related to the Tenebrionidse through Strongylium and other allied genera, it is always and invariably distinguishable by the pectination of the tar.sal claws; besides this there is, in the vast majority of genera, a marked and unmistakable peculiarity of facies which can seldom be mistaken. The porous system of the antennae is developed to an extent unknown in the Tenebrionida^, except in certain of the strongyliide genera, the entire surface of all but three or four of the basal joints being studded with large circular sparsely placed pits, which are filled with a white sensitive material of a spongy-pubescent nature. These pores are frequently so large as to be quite conspicuous under the lowest powers of amplification. The CistelidfE resemble the lower Tenebrionidae in the prolonga- tion backward at the sides of the third and fourth ventral segments, which is however more marked and general than in the latter family, and also in the well-developed coriaceous posterior margin of these "TO Coleopterological Notices, III. segments; also in the thinner integuments of the body, with soft and easily ruptured connective tissues. Perhaps some of the char- acters which the family in general possesses in common with the Strongyliini, indicate really a higher dev(!lopment than that of the Asidina; and Tentyriinte; tlie superior powers of perception indi- cated by the complex porous system of the antenna;, large eyes and more developed palpi, would, at any rate, seemingly point to this conclusion. As more important distinctive characters of the family, it may be said that the antennae and tarsi are usually long and slender, the basal joint of the posterior tarsi being more or less elongate. The anterior coxae are narrowly separated, the cavities always closed behind but never confluent, at least externally, although sometimes separated by a very thin lamina ; beneath this lamina they may possibly sometimes be confluent, but usually appear to be separated by a more or less thickened membrane. The eyes are generally large, sometimes extremel}^ so. The mandibles are small or moder- ate, arcuate and finely notched at apex, occasionally being nearly entire, but this character cannot be advantageously employed in classification, except in distinguishing closely allied genera. The genera with lobed tarsi appear, as a rule, to be more constant in generic as well as specific characters, than those with simple tarsi. The sexual characters of the male are generally strongly mani- fested in the eyes, antennae or genital api^aratus. The intromittent organ is more or less acutely pointed at apex, the under side being channeled, except very near the apex. Lying in this groove is a curious straight spike hinged at one end to a point of attachment within the channel, which can be placed in a position perpendi<;ular to the organ, and which probably locks the organ securely to the inner surface of the vagina. The strong hold thus obtained, is often abundantly evident by the great extrusion of the female viscera in specimens (;aptured in copula. It. is quite singular that this spike is not exhibited in any of the many elaborate and apparently care- ful drawings of Mr. Saunders published in the Biologia; it is often plainly visible, i)rojecting from the under surface of the penis in Ilymenorus. The abdomen consists of five segments in both sexes. The oedeagus proper is protected by a plate which is often extruded beyond but usually concealed beneath the fifth segment, the plate Coleoplerological Notices, Til. 71 being sometimes quite prominent behind in one or both sexes accord- ing to the genus-/ it is generally deeply bilobed in the male and more or less truncate in the female, but may occasionally be com- pletely non-lobcd in the male. Under the latter circumstances it has much the appearance of an additional segment, and is often designated the "sixth segnuMit." It is, however, not a segment in any such meaning as is attached to the other abdominal segments, but is a part of the genital apparatus, and should more properly be termed the "genital armature." It probably serves no other pur- pose than a guide or ])rotection to the oedeagus [)roper, the lobes of the male not constituting in any sense a clasping or locking organ. In view of the intricate affinities of the various genera and the complex, extremely prominent and greatly diversified sexual modi- fications of the antennoe, palpi, eyes, tarsi, fifth ventral segment and genital armature in the various species composing them, a general and exhaustive study of the Cistelidas would undoubtedly prove one of the most instructive but, at the same time, one of the most laborious works which could well be undertaken. In the absence of a sufficiently general knowledge of the family, I feel therefore, that the characters employed in the following table will, in many cases at least, be ultimately found to possess far less value than would, with the comparatively limited material at my service, appear to belong to them. However, as represented in our fauna the genera may for the present be distinguished by the following- characters :^ — 1 The group "Cteniopides" of Lacordaire will probably not prove to be entirely natural, and as there are extremely few genera — Andrimus (Cteniopus Lee), and possibly Androchirus — within our faunal limits which can be placed within it, I have disregarded it in the generic scheme which is here presented. A division into distinct groups, based upon the protrusion of the genital armature in both sexes, would give rise to difficulties analogous to those encountered in attempting to divide Mycetophila into distinct genera on certain j)rosternal characters, a statement of which will be given more fully under that genus. 2 I have been greatly aided in this investigation by material placed in my care by Prof. C. V. Riley and Mr. W. Jiilich, and also have to acknowledge vay indebtedness to Mr. Champion for tyjiical representatives of many of the Central American forms, which have been extremely useful in many cases besides tliat of proving the equality of Prostenus rafifornicus and Xystropus fulgidas. 72 Coleopterological Notices, III.

Prostenus Horn nee Latr. The head in Xystvopus is almost of the same form as in Helops and some other allied genera of Tenebrionidse ; in Stenoehidus it is of a more strictly eistelide type, but still the general form of body recalls the Tenebrionidre much more forcibly than any of the typi- cally eistelide genera which follow. In fact there seems to be some decided coordination between the form of the abdominal process and relationship with the Tenebrionida\ This is my reason there- fore for placing Xystropus and its allies first instead of last in the series. In Xystropus as represented by califorvicus, the eyes are small, short and strongly transverse, the antenna? moderate in length, stout, incrassate and compressed, the maxillary palpi moderate, with the apex of the fourth joint but moderately oblique and the angle at the base much less than right, resembling somewhat that of Helops californicus. The prosternal process is horizontal poste- riorly, then abruptly vertical to the level of the prosternal side- pieces, where it becomes strongly dilated, widely separating the latter at the posterior margin ; the hind coxae are distinctly sepa- rated by a rounded abdominal projection. The legs are short, the tarsi without lobes, clothed beneath with long coarse hair, and with the basal joint of the posterior unusually short. The ungues are Annals N. Y. Acad. Sci., VI, Nov. 1891.— 6 74 Coleopterological Notices, III. moderate in length, the outer contour almost evenly arcuate, the apex finely and acutely produced beyond the pectinate portion, the latter extending nearly to the base, the denticles fine, long and spini- form, gradually becoming very short toward base, eight or nine in number. The single tropical species which extends within our faunal limits may be described as follows •} — X. californicus Horn. — Trans. Am. Eut. Soc, 18G7, p. 138 (Prostenus) ; fulgidus Makl. : Act. Soc. Fenn., X, p. 680. — Oblong-oval, evenly, moderately convex, polished throughout, the upper surface metallic red, the under black with steel-blue reflection ; legs and antennae black throughout ; integuments devoid of fine pubescence, the upper surface bristling with long erect setae from the coarse punctures. Head coarsely, very sparsely punctured, the eyes small ; antennae one-half as long as the body, very stout, compressed, feebly attenuate through the last three joints, the ninth joint as wide as long, third distinctly longer than the fourth. Prothorax transversely oval, but little more than one-third wider than long, the sides feebly angulate at basal third ; disk without trace of impression or basal foveae, extremely coarsely, sparsely and unevenly punctate, the large circular punctures intermingled with smaller ones. Elytra between three and four times as long as the prothorax, and, in the middle, about two-fifths wider, acutely parabolic at apex, the sides feebly arcuate, the humeri rather narrowly rounded and broadly exposed, the disk with unimpressed series of rather coarse close-set punctures ; the intervals each with a single series of widely distant punctures, which are very much larger than those of the striae. Abdomen finely, sparsely punctured. Legs short, slender, the tarsi somewhat compressed, short, the basal joint of the posterior but slightly longer than the next two combined. Length 9.3 mm. ; width 3.5 mm. California; Mexico; Panama; Colombia. The representative from Panama, sent me by Mr. Champion, is precisely similar in every detail to the single specimen of Frostenus californicus in the LeConte cabinet at the Cambridge Museum. This indicates a distribution which certainly could not have been anticipated from analogy, at least in the present family. LYSTRONICHUS Latr.

Ceut.-Amer., Coleopt., IV, Pt. i, Nov. 1888, p. 4ti2. I have not seen any representative of this species. It is proba- ble, however, from the remarks made by Mr. Champion, that it will ultimately have to be separated from the more typical forms of the genus. It is " oblong-ovate, feebly convex, obscure reddish-brown, opaque, above usually of a pruinose bluish-violet, obscure purplish, or green- ish-bronzy tint, the surface somewhat thickly clothed with long erect hairs, and also sparsely pubescent." The antennte are "very long, slender and filiform," and the elytra have "rows of very minute punctures placed upon obsolete striae." Length 6.0-8.3 mm.; width 2.0-3.5 mm. STEIVOCHIDIJS Lee. In this genus the posterior coxa? are moderately separated by a short abdominal projection, which is evenly rounded at apex and quite similar to that of Xystropus, the anterior being separated by a rather wide, longitudinally convex prosternal process, which is strongly declivous and gradually attenuate behind. The legs are long and slender, the penultimate joint of all the tarsi strongly lobed beneath, the antepenultimate joint of the anterior and inter- mediate also lobed but less strongly, that of the posterior simple ; these modifications are independent of sex. The mandibles are distinctly notched at apex, the two lobes sub- equal. The fourth joint of the maxillary palpi is elongate, more or less recti-triangular, and differs sexually in form as described below under *S'. gracilis ; the last joint of the labial is short and robust, wider than long, with the inner side slightly shorter than the outer. The ungues are moderate in size, the external outline more arcuate near the apex, the latter being finely and acutely produced beyond the pectination, which is long and rather fine, the denticles six or seven in number. The general form of the body is elongate and convex, the pro- thorax subcylindrical, the integuments being more or less strongly granulato-reticulate and completely glabrous. The wings are well developed. 76 Coleopterological Notices, III. Stenochidus seems more closely related to Xarses Champ, than to any of the other Central American genera, but the general aspect of the species must be quite different. Our species are only two in number and may be thus distinguished : — Very dull, the legs black, with the basal three-fourths of the femora red. gracilis More shining, the eljtral punctuation more distinct; legs black throughout. cyanescens S. gracilis Lee. — Ann. Lye. N.

Head and pronotum somewhat coarsely, very densely punctate; eyes small; antennae long and slender, gradually incras- sate. Prothorax quadrate (male) or very slightly transverse (female), the apex transversely truncate, almost as wide as the base, the latter very feebly bi- sinuate ; basal angles slightly obtuse and quite distinctly blunt ; sides nearly parallel and feebly arcuate, slightly more convergent near the apex ; disk feebly, cylindrically convex, not impressed ; fovese obsolete. Elytra three and one-half times as long as the prothorax and nearly one-half wider, rather abruptly, obtusely ogival in apical third ; sides nearly straight, parallel ; humeri narrowly rounded and broadly exposed at base ; disk with fine, minutely punctate striae ; intervals not distinctly punctate. Abdomen more shining, finely, sparsely punctate. Legs very long and slender, the hind tarsi much shorter than the tibiae, with the basal joint distinctly longer than the remainder. Male. — Eyes separated by two-thirds more than their own width ; antennse two-thirds as long as the body, slender, feebly incrassate, the ninth joint fully twice as long as wide ; maxillary palpi with the fourth joint rather more than twice as long as wide, the angle at the support distinctly more than right, the apex a little longer than the outer side ; abdominal punctures strong, becom- ing closer toward apex, the fifth segment entire at apex, with the surface broadly feebly impressed along the middle. Female. — Eyes separated by fully twice their width ; antennte one-half as long as the body, gradually, rather strongly incrassate, the ninth joint obconical, one-half longer than wide ; fourth palpal joint recti-triangular, twice as long as wide, the apex not at all longer than the outer side ; abdomen very minutely, feebly, sparsely and evenly punctate throughout.

This species greatly resembles gracilis, but is more slender and rather less convex, M'ith the legs entirely black, and the punctures of the elytral striae much larger and more conspicuous. All the specimens before me are deep black, but, as the name indicates, the color may perhaps occasionally be of a bluish tinge. LOBOPODA Sol. Allecula Say, Lee. The species of Lobopoda are, as a rule, above the average of the family in point of size, and are sometimes surprisingly closely allied among themselves. The form is generally more or less oblong-oval and gradually pointed behind, and the punctures of the elytral series are almost invariably finer or more or less linear toward apex, often becoming completely obsolete. The tarsal lobes are especially highly developed, and generally differ sexually to a marked degree, the lobes of the penultimate joint being, however, usually free from sexual modification. Attempts have been made to subdivide the genus upon the basis of variation in the number and disposition of the lobed joints in the male and female, but, as in most characters of this nature, there are so many intergrading forms, that these efforts have only met with partial success. These tarsal modifications are useful, however, in tabulating the 78 Coleopte7'ological Notices, III. species, but as the number of representatives within the limits of the United States is comparatively small, and as the male of several of our species is still unknown to me, I have, in the following- pre- liminary table, simply employed general characters relating to superficial forai and sculpture, and based upon the limited material before me. Our species as far as known may be distinguished as follows: — Pronotal punctures very sparsely and unevenly distributed, generally more or less densely aggregated along the median line and in front of the scutellum. Pronotum rather polished, the punctures circular and perforate socia Pronotum exceedingly dull and alutaceous, the punctures larger, uneven in size, shallow, elongate and variolate SllllCUlieata Pronotal punctures more closely placed and evenly distributed, impressed. Eyes in the female separated by approximately one-half their width. Eyes in the male not quite contiguous, their inner margins broadly rounded punctulata Eyes in the male subcontiguous along a long fine straight double line. ociilatifrons Eyes in the female separated by distinctly less than one-half their width; legs usually red throughout eryflirociiemis Eyes in the female separated by fully their own width atra A number of additional species will almost undoubtedly be dis- covered when southern Texas is more thoroughly and systemati- cally explored.

It is very closely allied to mexicana Champ., but differs from the corresponding sex of that species in its slightly closer punctuation on the elytral inter- vals ; there are usually but two punctures in a transverse direction in mexicayia, while in socia there are about three, which are rather smaller than in the former. This is the only decided difference of any kind which it is possible to discover, but I think that the two species are distinct and that this would be clearly evident if the males were compared. The elytra are perfectly simple and nar- rowly rounded at apex in the female of socia. This species is not at all closely related to punctulata. I,.

The unique specimen, which is fortunately a male, represents a remarkably distinct species, not at all closely related to any other here described, and readily known by its cuneate elytra, dull lustre and peculiar pronotal punctuation. The anterior tibia? of the male are broadly, very obtusely toothed internally at basal two-fifths, this character being common to the males of a large number of species; in punctulata and oculatifrons it is more nearly in the form of a broad swelling.

The elytral intervals are slightly more sparsely punctured in the male than in the female. Punctulata may be distinguished at once from socia by the pronotal punctuation, the punctures being widely dispersed except toward base and narrowly along the middle in the latter, and the size of socia is much greater. In punctulata the eyes are not absolutely contiguous in the male, but are separated by a narrow setose isthmus; in oculatifrons they are contiguous along a fine straight double line which is however also setigerous. li. oculatifrons n. sp. — Elongate-oval, moderately convex, black throughout ; anterior tarsi ferruginous ; antennse piceous, gradually paler toward apex ; lustre polished throughout, the pubescence rather long, fine, moderately sparse, piceo-fulvous in color and not at all conspicuous.

This species, while allied to x)^'-nctidata, may be easily distin- guished by its larger size, more parallel and subquadrate prothorax, intense black color, the larger eyes of the male and the decidedly denser elytral punctuation especially of the female. The difference in the density of elytral punctuation of the male and female is extremely pronounced. 82 Coleopterological Notices, III. li. erytlirocneillis Germ. — Ins. Spec.

Louisiana, The male above noted has the legs piceous-black, and the same condition exists in one of the females. Two other females have the legs normally red throughout, the species is apparently variable therefore in this respect. It may be distinguished from punclulata by its smaller size and much sparser, feebler pronotal punctures, as well as the more approximate eyes of the female, although in the male they do not appear to be quite as approximate as in the cor- responding sex of punctulata. As remarked by Mr. Champion, erythrocnemis is allied to the Mexican Isevicollis, but the latter differs in its longer, more slender form and still sparser, more un- evenly dispersed pronotal punctuation. Erythrocnemis probably inhabits the Mississippi valley as far to the northward as southern Illinois. Li. atra Say. — Journ. Ac. Phil., V, 1827, p. 242; nigrans Melsh : Proc. Ac.

Connecticut; Pennsylvania. The present species is chiefly notable for its extreme northern habitat. The eyes are much smaller than in any of the others here enumerated, and it is also remarkable in having the punctures of the elytral strias unusually coarse and conspicuous toward base; but, as is often the case, they become completely obsolete toward apex. HYMENORUS Muls. The two genera Lobopoda and Ilymenorus are peculiarly Ameri- can, and together comprise probably more than one-half of the entire family in our continent, the former being essentially tropical but entering the southern parts of the United States in moderate number, and the latter northern in its distribution but overrun- ning Mexico with many species. Hymenorus is a nearctic, and, to some extent also, a palsearctic genus, while Lobopoda is entirely neotropical. Hymenorus is one of the best defined of our genera, although the species are comparatively diversified in facies. The species are as a rule much smaller than those of Lobopoda. The lobes of the tarsi in Hymenorus generally differ from those of Lobopoda in being small, and never more than two in number on the two anterior and one on the posterior pair. The last joint of the maxillary palpi is usually in the form of a right angled tri- angle, with the apex and the outer side subequal in length, but rarely it becomes more dilated and quite similar to the prevailing type in Lobopoda and Allecula. The anterior coxse are always separated by a narrow but distinct prosternal process, and the posterior by a narrow acutely angulate abdominal projection, the entire structure 84 Coleopterological Notices, III. of the under surface being surprisingly constant throughout the genus when compared, for example, with that of Mycetophila. The posterior tarsi are always slender, with the basal joint elon- gate and sometimes slightly less, but often much greater, in length than the remainder. The punctuation and pubescence are, as a rule, rather dense, the latter pale, somewhat short, coarse and con- spicuous. The eyes are generally moderate and subequal in size in the two sexes, but sometimes larger, approaching the form seen in Lobopoda ; they are then nearly always subject to the sexual modi- fications characterizing that genus. The antenna are usually slen- der and filiform, moderate in length, with the joints more or less obconical, sometimes stouter and distinctly attenuate toward apex, the third joint being nearly always equal to or slightly longer than the fourth and similar in the sexes, but in a moderate number of species becoming very short in the male, although still normal in the female. The general form of the body is oblong or oval, rather compact, with the prothorax subequal in width to the base of the elytra, the humeri never being in the least broadly exposed at base. The elytra are almost invariably distinctly punctate-striate, although in many cases the strial punctures become obsolete toward apex as in Lobopoda, and in one instance — inquilinus — the strife are com- pletely effaced throughout, being traceable with great difSculty only in the immediate neighborhood of the base. While the species are usually constant and easily separable among themselves by marked structural differences, sexual or otherwise, I have found the tabular classification of them a most difficult and unsatisfactory problem. None of the structural peculiarities so valuable in separating allied forms, continue constant throughout a sufficient number of species to enable us to define large groups with rigorous exactness, and I have been forced finally to adopt a method of subdivision depending largely upon general habitus and sculpture. There are probably but few species common to the United States and Mexico, at least below the latitude of Durango. Mr. Cham- pion has kindly sent me representatives of his emmenastoides, palli- dus, colonoides, guatemalensis and americanus, all of which are widely different from any species which we possess. The densely punctate species, so characteristic of the southwestern fauna, are for the most part more or less local in distribution, contrasting strongly Coleopterological Notices, III. 85 ill this respect with the more northern and eastern polished and sparsely punctate forms. It is hoped that the following table may aid somewhat in identi- fication, but as there are undoubtedly many species yet to be dis- covered, it will proliably prove more or less ambiguous unless used solely as a key to the descriptions : — Punctuation of the elytral intervals confused or forming more than a single series 2 Punctuation of the elytral intervals forming a single even series 23 2 — Entire upper surface polished, the pronotal punctuation sparse ; basal joint of the hind tarsi generally much longer than the remainder ; antennae variable in lengtli and structure, the third joint often sexually modified 3 Upper surface generally more or less dull, the pronotum densely punctured ; third joint of the antennae not noticeably modified sexually 8 3 — Third antennal joint of the male equal or subequal in length to the fourth 4 Third antennal joint of the male distinctly shorter than the fourth 7 4 — Elytral strise obsolete toward apex 5 Elytral stripe distinct throughout tlie length G 5 — Elytra with a large humeral red spot ; size very small....!

One of these, represented \)x twelve specimens, is rather more slendcn* than the ty})c, with bright flavate leys and piceous upper surface, tlic elytra being feebly and suffusedly rufescent toward base. Another, reitresented by a single si)ecimen from Florida, has the pronotum rather coarsely punctate, and the eyes larger. Still anotluir, represented by a single male from Fiidiana, is larger, witli the pronotum very fiiuily punctate, the eyes being large and sepa- rated by less than their own width. At a future tinm, with more material, it will be my endeavor to pro|)erly deline these allied forms. 3 II. iiifliscatlis n. sp. — Oblong-oval, moderately convex, polished tliroiij^lioiit, daiiv biownish-piceous, the under surface and legs slightly paler, rufescent ; pubescence rather long and coarse, somewhat sparse but conspicu- ous. Head feebly convex, rather coarsely but feebly, sjjarsely punctate ; eyes small, separated by two-fifths more than their own width; antennje slender, the third and fourth joints slender and equal. Proihorax transverse, about four-fifths wider than long, the apex broadly, feebly arcuate, three-fifths as wide as the base, the sides very strongly rounded and convergent anteriorly, becoming parallel and almost straight in basal half, the basal angles right and narrowly rounded ; base transverse and straight laterally, broadly, roundly lobed in the middle, the lobe more prominent post(n'iorly than the lateral por- tions ; disk obsoletely inii)r('ssed toward base in the middle and in the j^osition of the usual foveas, rather coarsely and sparsely punctate. Elijtra four times as long as the prothorax, and, behind the middle, just visibly wider than the latter, acutely ogival in apical third ; sides very feebly arcuate, especially behind, thence nearly straight to the base and continuous with those of the prothorax ; disk with feebly impressed rows of rather small but distinct, rounded punctures which become obsolete toward apex, the intervals feebly convex, finely, confusedly and rather sparsely punctate. Alxhmcn minutely, sparsely punctate throughout. Lega slender, the basal joint of the hind tarsi eijual in length to tlie remainder. Length ft. 7 mm. ; width 2.2 mm. California (Los Angeles). The single specimen before me is a male. The s))ecies does not greatly resemble any other, although perhaps most closely allied to niger. The pubescence is unusually long, and the prothorax short and coarsely punctate. 4 II. picipeilllis n. sp. — Oblong-oval, rather feebly convex, piceous- black above, the elytra sligtitly paler, jiiceous ; under surface piceous-black, the legs concolorous ; tarsi and antennie slightly paler, dark brown ; surface highly polished throughout, the pubescence moderate in length, coarse, pale, decidedly sparse. Hrmf very sparsely, coarsely punctate, the eyes rather large, separated by two-thirds to three-fourths their own width ; anteiuu'e Coleopte7'ological Notices, III. 91 long, somewhat robust, one-half as long as the body, the joints equal in length throughout, the intermediate strongly obconical and nearly twice as long as wide, the third very long, cylindrical and slightly longer than the fourth. Prolhorax two-thirds to three-fourths wider than long, somewhat parabolic and strongly rounded at apex, the sides becoming parallel and distinctly arcuate in basal half to two-thirds, the angles nearly right, not rounded ; base transverse, the sinuations rather narrow and distinct ; disk scarcely impressed, very finely and sparsely, somewhat feebly punctate. Elytra four times as long as the prothorax and subequal to the latter in width, gradually very acutely ogival toward apex, the sides parallel and scarcely visibly arcuate ; disk with feebly impressed series of punctures, which are rather coarse and distinct toward base, but almost completely obsolete toward apex, the intervals minutely very sparsely punctate, tliese punctures becoming rather coarser and more asperate toward apex. Abdomen minutely, sparsely punctate throughout. Z^(/s slender ; femora rather robust, sparsely punctate ; basal joint of the hind tarsi unusually long, fully one-half longer than the remainder. Length 7.0 mm. ; width 2.6-2.8. Michigan. The species above described is not likely to be confounded with any other, being distinguishable by its long antennae with strongly obconical joints, the third a little longer than the fourth — which is unusual in this section, — its larger eyes and incomplete elytral series. It also differs in its very fine, extremely sparse pronotal punctuation. The two specimens before me are apparently females. 5 H. punctulatus Lee— Proc. Ac. Phil., 1859, p. 78.— Oblong-oval, moderately convex, polished and pale rufo-testaceous throughout, the pubes- cence line, short, subrecumbent, pale but rather sparse and not conspicuous. Ilead rather large and strongly convex, somewhat coarsely, sparsely punctate, the eyes small, separated by two-fifths more than their own width ; antennae rather short and robust, distinctly attenuate toward apex, but little more than one-third as long as the body, the intermediate joints somewhat feebly obconical, the third and fourth subequal. Prothorax strongly transverse, about twice as wide as long, the apex broad and subtruncate, the base trans- verse, broadly, feebly arcuate in the middle ; sides broadly arcuate and con- vergent in apical two-fifths, thence nearly parallel to the basal angles which are obtuse and rather blunt; disk scarcely at all impressed, finely, rather densely punctate, the punctures separated by about twice their own diameters. Elytra nearly five times as long as the prothorax and rather distinctly wider, somewhat abruptly ogival in apical third ; sides parallel and just visibly arcuate ; humeri rounded and oblique externally, but not exposed at base ; disk with feebly impressed series of fine, rather approximate punctures, the intervals minutely, confusedly and* somewhat sparsely punctate. Abdomen minutely, rather feebly and sparsely punctate. Length 6.3 mm.; width 2.6 mm. 92 Coleopterological Notices, III. California. Cab. LeConte. Although bearing a general resemblance to the obscurus group of eastern species, punctulatus differs remarkably from all of them in its fine and much shorter pubescence. The type specimen is a male, and is in a poor state of preservation, the pronotura being- broken and crushed so that it is somewhat distorted in outline; the above measurements have made allowance for this as far as possible. The posterior legs are entirely wanting in the type. It is distin- guishable from infuscatus by its broader form, relatively shorter prothorax and longer elytra, shorter, stouter antennte and short pubescence. The antennae are quite robust, unusually compact and cylindrical, with the third joint just visibly longer than the fourth and both of these much longer than joints five to eleven, which are equal in length, the fifth about one-half longer than wide, the tenth nearly two and one-half times as long as wide. 6 H. melsheimeri n. sp. — Oblong-elongate, parallel, moderately con- vex, piceous-black above, the entire under surface, legs and antennae paler, rufo-ferruginous ; surface polished ; pubescence nearly as in obscurus. Head rather coarsely, deeply, sparsely punctate, the eyes moderate, separated by slightly more than their own width ; antenn?e short, stout, filiform, not more than one-third as long as the body, the last three joints rapidly shorter, joints three to nine equal in length, the intermediate almost parallel, twice as long as wide. Prothorax three-fourths wider than long, the apex broadly arcuate, continuous in curvature around the apical angles, the sides becoming parallel and feebly arcuate almost through basal two-thirds ; basal angles right, not rounded ; base transverse, with a short rounded median lobe ; disk obsoletely impressed only along the middle toward base, finely, sparsely punctate, the punctures round, perforate and separated by about three times their own diameters. Eli/tra nearly four times as long as the prothorax and equal to it in width, rather gradually, acutely pointed in apical third ; sides parallel and nearly straight ; disk with feebly impressed series of fine, not very close-set and inconspicuous punctures, the intervals minutely, sparsely punctate. Abdomen finely, sparsely punctate. Legs slender ; basal joint of the hind tarsi nearly one-half longer than the remainder, slightly arcuate. Length 7.3 mm. ; width 2.7 mm. Michigan. The unique specimen before me is immediately distinguishable from any other in this section by its narrower, more parallel form, and unusually short, rather stout, but filiform antennge, with nearly parallel-sided joints. The sex of the type cannot be definitely deter- mined without dissection. Coleopterological Notices, III. 93 7 H. obesilS n. sp. — Broadly oWong-oval, rather strongly convex, polished throughout, plceous-black, the abdomen black ; legs piceous, the tarsi paler; antennae rufo-fuscous ; pubescence moderate in length, rather sparse, coarse, pale in color. Head sparsely, somewhat coarsely punctate ; eyes moderate, separated by a little less (male), or a little more (female), than their own width ; antennae slender, filiform, two-fifths as long as the body, the joints nearly parallel, gradually slightly shorter toward apex, the third a little shorter than the fourth in the male, slender, the fourth three times as long as wide. Prothorax two-thirds to three-fourths wider than long, the apex two- thirds as wide as the base, broadly arcnate, the sides parallel and feebly arcuate in basal half, thence rather strongly convergent and arcuate to the apex ; basal angles distinctly obtuse and blunt ; base transverse, the sinua- tions rather broad and feeble ; disk scarcely at all impressed, moderately coarsely, strongly, sparsely punctate. Elytra from three and one-half to nearly four times as long as the prothorax, toward base barely perceptibly wider than the prothorax, a little more distinctly so posteriorly, rather broadly, obtusely ogival at aj)ex ; sides feebly arcuate ; disk with feebly impressed series of small, deep, close-set punctures, the intervals finely, rather sparsely punctate in the female, very sparsely so in the male. Abdomen finely, sparsely punctate throughout. Legs slender ; basal joint of the hind tarsi much longer than the remainder. Length 6.7-8.0 mm. ; width 3.2-3.5 mm. New York. The broadly oval form and more slender, filiform antennae of this species will serve to distinguish it from pilosus, to which it is rather closely allied. The third antennal joint of the male is slightly shorter, and the outer joints decrease more conspicuously in length, than in pilosus, and the eyes in the same sex are distinctl}^ larger. 8 H. pilosus Melsh.— Proc. Ac. Phil., Ill, 1846, p. 58.— Rather broad, oblong-oval, moderately convex, black or piceous black throughout, the abdo- men, legs and antennae concolorous, the tarsi paler, rufescent; surface polished throughout ; pubescence moderate in length, pale, coarse, rather sparse but conspicuous. Head coarsely, deeply, somewhat sparsely punctate, the eyes moderate, separated by from one-third to one-fourth more than their own width ; antennae slender, filiform, two-fifths as long as the body, the joints quite distinctly obconical, more than twice as long as wide, the third and fourth long, exactly equal in both sexes. Prothorax three-fourths wider than long, the apex broadly arcuate, three-fourths as wide as the base, not evenly continuous with the sides, the latter convergent and almost evenly arcuate from base to apex in both sexes ; basal angles right and distinctly blunt ; base transverse, the sinuations rather broad and feeble ; disk scarcely at all impressed, quite coarsely, deeply, strongly punctate, the punctures separated by two to three limes their diameters in the male, rather closer in the female. Elytra nearly four times as long as the prothorax, and, at the middle, slightly wider, rather obtusely rounded behind, the sides parallel and just visibly 94 Coleopterological Notices, III. arcuate, the linmeri broadly oblique to the base of the prothorax ; disk with distinctly impressed series of small deep punctures, the intervals sparsely, finely punctate in both sexes. Abdomen minutely, very sparsely punctate throughout, rather more closely so in the female, the metasternum coarsely, sparsely so externally. Legx slender, the basal joint of the hind tarsi one- third longer than the remainder. Length 7.0-8.0 mm. ; width 2.9-3.2 mm. Massachusetts; Michigan; Virginia. This species is more northern in distribution than ohscurus, and is easily distinguishable by its shorter prothorax, coarser punctua- tion, rather broader, more depressed form, black color and long third antennal joint of the male. The series before me is quite homogeneous. Two specimens from Florida are not included in the measure- ments given above, as they appear to represent a much smaller, though very closely allied species. It will require larger series to definitely solve this question. 9 H. difHcilis n. sp. — Elongate, sub-oval, rather strongly convex, pice- ous-black throughout, the tarsi paler ; surface highly polished, the pubescence rather long, coarse, pale, moderately dense. Head coarsely punctate, the punctures very sparse between the eyes, but dense along the base ; eyes moderate, separated by their own width ; antennae about one-half as long as the body, robust, strongly compressed, feebly attenuate, joints four to eleven equal in length, very strongly obconical, nearly twice as long as wide, the third joint short, about two-thirds as long as the fourth in the male. Prothorax long, about one-half wider than long, broadly, rather strongly arcuate at apex, the sides parallel or very feebly convergent and nearly straight in basal two- thirds, then rounded into the apex ; basal angles right, not at all roiinded ; base transverse, the sinuations very broad, distinct ; disk with obsolete median sub-basal impression, very coarsely, deeply punctate, the punctures round, separated by nearly twice their own widths. Elytra about three and one-half times as long as the prothorax, and, in the middle, slightly wider, rather obtusely ogival at apex; sides parallel and just visibly arcuate; disk with unusually broadly, deeply im^jressed series of punctures, which are coarse, deep and very conspicuous toward base, but finer, though still distinct, toward apex ; intervals rather strongly convex toward the suture, finely, sparsely punctate. Abdomen finely, very sparsely punctate throughout. Legs slender ; basal joint of the hind tarsi distinctly longer than the remainder, though rather shorter than usual in this section. Length 7.3 mm. ; width 3.0 mm. New York. The unique type is a male. The species is not very closely related to any other, and may be distinguished from pilosus by its more slender form, more elongate prothorax and short third antennal ColeojDlei'ological Notices, III. 95 joint of the male. From obscurus it may be known by its coarser pronotal punctuation, and more robust and compressed antennae with more strong-ly obeonical joints and with long-er third joint in the male, and finally from perforatus, by its longer, rather less coarse]}'- and more evenly punctate pronotum, much shorter antennae and relatively narrower elytra. 10 H. perforatus n. sp. — Oblong, moderately convex, polished through- out, dark piceous-brown, the legs and antennae slightly paler and more ferru- ginous ; pubescence rather long, coarse, semi-erect, pale, moderately dense and conspicuous. Head coarsely, deeply but rather sparsely punctate, the eyes rather large, separated by about their own width in the male ; antenna about one-half as long as the body, filiform, rather stout, the joints feebly obeonical and more than twice as long as wide. Prothorax fully three-fourths wider than long, the apex broadly, strongly arcuate and continuous in curva- ture with the sides, which become parallel and feebly arcuate in basal half, the angles right, not rounded ; base transverse, the sinuations broad and feeble ; disk obsoletely impressed along the middle, the basal foveas nearly obsolete, the surface very coarsely, deeply punctate, the punctures sparse, separated generally by nearly twice their own diameters. Eljtra a little more than four times as long as the prothorax and about one-fifth wider, obtusely ogival in less than apical third ; sides parallel and nearly straight, the humeri nar- rowly, abruptly rounded to the prothorax and exposed at base ; disk with rather strongly impressed series of somewhat coarse, deep punctures, the intervals feebly convex, finely, sparsely, confusedly and rather unevenly punctured. Abdomen sparsely, finely punctate. Legs slender, the basal joint of the hind tarsi a little longer than the remainder. Length 7.5 mm. ; width 2.8 mm. Pennsylvania ; Indiana ; North Carolina. The three specimens before me are males; in this sex the third antennal joint is fully two-thirds as long as the fourth. Although belonging to the same division of the genus as obscu- rus, the present species differs greatly in its extremely coarse pro- notal punctuation, and in having the elytra abruptly and distinctly wider than the prothorax. 11 H. Clirticollis n. sp. — Oblong-oval, rather depressed, black with a piceous tinge throughout, the tarsi, antennae near the base and palpi paler, rufescent ; surface highly polished, the pubescence coarse, pale, sparse and unusually long. Head coarsely, deeply, rather sparsely punctate, the eyes moderate, separated by scarcely their own width in the male and but slightly more in the female, the antennae slender, filiform, scarcely perceptibly com- pressed, rather more than one-half as long as the body, the joints strongly obeonical, twice as long as wide, the third very short in the male and scarcely one-half as long as the fourth. Prothorax short, fully four-fifths wider than 96 Goleopterological Notices, III. long, strongly but broadly arcuate at apex, thence broadly but more strongly arcuate laterally, the sieles becoming feebly divergent and feebly arcuate to the basal angles, which are right and distinctly blunt ; base transverse, the sinuations narrow and strong ; disk scarcely impressed, coarsely, deeply, sparsely punctate. Elijtra nearly four times as long as the prothorax, and, in the middle, just visibly wider in the male, quite distinctly wider behind the middle in the female, rather obtusely ogival at apex, the sides very feebly arcuate, becoming nearly straight toward base ; disk with rather distinctly impressed series of moderately coarse, deep, punctures, the intervals finely, sparsely punctate. Abdomen finely, sparsely punctate. Legs slender, the basal joint of the hind tarsi much longer than the remainder. Length 5.7-6.5 mm. ; width 2.4-2.8 mm. Iowa. A somewhat small, broadly depressed species for the present section of the genus, with rather short prothorax, the sides of which are unusually convergent from the base. It is easily recog- nizable by its longer, more shagg}' pubescence, as well as by the antennal structure of the male. The anterior tarsi of the male have the third joint very rudimen- tarily lobed, the fourth distinctly so ; the intermediate and posterior tarsi having simply the penultimate joint lobed beneath. 12 II. olisciirus Say.— Journ. Ac. Phil., V, 1827, p. 242.— Oblong-oval, strongly convex, blackish-piceous, the abdomen, legs and antennse slightly paler, rufo-piceous, polished throughout, the pubescence rather long, coarse, pale, moderately dense and conspicuous. Head somewhat coarsely, sparsely punctate, the eyes moderate, separated by about their own width in both sexes ; antenna slender, filiform, two-fifths as long as the body, joints four to eleven equal in length, barely perceptibly obconical, much more than twice as long as wide, the third very short and one-half as long as the fourth in the male, long and fully equal to the fourth in the female. Prothorax rather long, but slightly more than one-half wider than long, almost semi-circularly rounded in anterior half, the sides thence feebly divergent (male), or parallel (female) to the base and feebly but distinctly arcuate ; basal angles right and slightly blunt ; base transverse, the sinuations narrow and strong ; disk obsoletely impressed in the middle toward base, and also in the position of tlie basal fovese, not very coarsely, deeply, s^jarsely punctate. Elytra scarcely three and one-half times as long as the prothorax, and, toward base, equal in width to the latter, somewhat broader behind the middle in the male, almost parallel in the female, the apex rather abruptly ogival ; disk with rather strongly, broadly impressed series of small, rounded, distinct punctures, the intervals rather closely punctate in the female, more sparsely so in the male. Abdomen finely, sparsely punctate throughout in both sexes, the metasternum very coarsely, sparsely so externally, gradually finely and more densely so Coleopterological Notices, III. 9T toward the middle. Legs slender ; basal joint of tlie hind tarsi fully one-third longer than the remainder. Length 6.2-7.5 mm.; width 2.7—3.1 mm. Texas ; New York. The typical form above described is from Texas, the Long- Island specimen being- quite similar, except that the pronotum is rather more finely punctured and the elytral series not so strongly im- pressed, tending to disappear laterally toward apex. It is singular that in these species the elytral punctuation of the male is quite distinctly sparser than that of the female, but the antennae seem to be al)Out equal in length in the two sexes. Still more striking sexual differences in punctuation will be alluded to wvifieY discretus} This species is easily separated from the others of this section by the characters given in the table. 13 H. COmiUUllis Lee. — New Spec. Col., 186(5, p. 135. — Oblong-oval, rather pale rufo-castaneous throughont, polished, the pubescence moderate in length, coarse, pale, rather sparse. Head coarsely, sparsely punctate ; eyes moderate, separated by slightly more than their own width ; antennae (male) slender, filiform, two-fifths as long as the body, joints five to eleven equal in length, very slightly obconical, distinctly more than twice as long as wide and each a little shorter than the fourth, the latter about twice as long as the third. Protliorax two-thirds wider than long, broadly, strongly arcuate at apex, the sides feebly convergent from the base nearly to the apex and rather strongly evenly arcuate ; basal angles scarcely more than right, not distinctly blunt ; base transverse, the sinuations broad and rather feeble, disk scarcely impressed, rather coarsely, sparsely punctate, the punctures separated by two to three times their width. Elytra equal in width to the protliorax and nearly three and one-half times as long, rather abruptly, obtusely ogival at apex, the sides parallel and nearly straight ; disk with distinctly impressed series of rather coarse deep punctures, which extend distinctly to the apex ; inter- vals finely, very sparsely punctate. Abdomen finely but strongly, sparsely punctate. Legs slender, the basal joint of the hind tarsi much longer than the remainder. Length 5.3 mm. ; width 2.2 mm. North Carolina. The description is drawn from the male as I have not positively identified the female. In this male type the last joint of the maxil- lary palpi is rather large and elongate, but almost perfectly recti- triangular, with the outer side subequal to the apex, and the elytral series are distinct to the apex. This is the smallest species of the present group except humeralis, and does not appear to be at all common. 1 The sparser elytral punctuation of the male is also a common character iu Lobopoda. 98 Coleopterological Notices, III. 14 H. discrepans n. sp. — Elongate-elliptical, rather strongly convex ; protliorax rather dull, the elytra polished ; body dark piceous-brown in color, the legs scarcely jialer, the abdomen and antennae paler and more rufescent ; pubescence rather long, coarse, subrecumbent, pale, sparse and somewhat conspicuous. Head coarsely and rather sparsely punctate, polished ; eyes large, separated by two-fifths their width ; antennse somewhat slender, not attenuate, two-fifths as long as the body, the joints very feebly obconical, nearly twice as long as wide, the third subequal in length to the fourth but much more slender. Prothorax nearly two-thirds wider than long, the apex bi'oadly arcuate, but slightly more than one-half as wide as the base, the latter transverse, with the sinuations very small but distinct ; sides broadly rounded and strongly convergent anteriorly, nearly straight and parallel in basal two-fifths, the basal angles right and not at all rounded ; disk not noticeably impressed, not very coarsely and extremely densely punctate, the punctures closely crowded and the lustre dull. Elytra three and one-half times as long as the prothorax, and, at the middle, but very slightly wider, gradually and acutely ogival in more than apical third ; sides feebly arcuate and continuous with those of the prothorax ; disk with fine, feebly impressed striae of rather small but distinct punctures, the intervals finely and sparsely punctured. Ahdonicn finely, sparsely punctate. Legs slender, normal. Length 5.5 mm. ; width 2.1 mm. California. This is quite a distinct species, readily distinguishable by its extremely densely crowded punctuation of the pronotum and cor- respondingly sparse elytral punctures, also by its large eyes and rather long pubescence. The fifth ventral segment is broadly feebly impressed in the single specimen before me, which is probably a male. 15 H. grandicollis Champ. — Biol. Cent.-Amer., Coleopt., IV, Pt. i, p. 429. — Oblong-oval, strongly convex, rather pale piceous-brown throughout, the under surface, legs and antennae but slightly paler ; lustre rather dull and alutaceous ; pubescence short, rather fine, pale, moderately dense. Head somewhat densely punctured, the eyes in the male large and separated by one-fourth or one-fifth of their width ; antennse rather slender, two-fifths as long as the body, not at all attenuate, joints three to eleven equal in length, somewhat distinctly obconical and rather more than twice as long as wide. Prothorax nearly two-thirds wider tlian long, the apex broadly, rather strongly arcuate and almost continuous in curvature with the sides, the latter broadly, strongly arcuate, becoming slightly convergent and feebly arcuate toward base, the angles slightly obtuse but not rounded ; base transverse, the sinua- tion at each side of the middle rather narrow but strong ; disk not distinctly impressed, finely, very densely punctate and dull, the punctures rounded and deep near their anterior margins, shallow and evanescent posteriorly, the interspaces very minutely and strongly granulato-reticulate. Elytra three Coleopterological Notices, III. 99 times as long as the prothorax and exactly equal in width to the latter, gradually ogival in ajjical tliird ; sides parallel and nearly straight in hasal three-fifths ; disk finely, feebly striate, the striae rather feebly and finely punctate, the intervals dull and alutaceous, finely, feebly, somewhat densely punctate. Ahdomen finely, somewhat sparsely and evenly punctate through- out. Lega slender, the basal joint of the hind tarsi nearly one-tliird longer than the entire remainder. Length 7.0-7.3 mm. ; width 2.8-3.0 mm. Arizona. A rather larg-e, smooth and dull species, somewhat allied to poro- sicornis and resembling the latter almost perfectly in outline and size, but easily distinguishable by its dull lustre, finer and much denser i)unctuation and strikingly more elongate basal joint of the hind tarsi, the comparison being made from the males. In the present species the latter sex is the only one before me ; the colora- tion in these two specimens is probably abnormally pale from im- maturity. 16 H. apaclieaniis n. sp. — Oblong-oval, ratlier convex, dark blackish- castaneous above and beneath, the abdomen, legs and antennae slightly paler and rufescent ; lustre dull ; pubescence extremely short, dense, pale, subseri- ceons and moderately conspicuous, recumbent. Head dull, finely, very densely punctate anteriorly, more sparsely so between the eyes, which are large and separated by scarcely two-fifths their own width ; antennae stout, just percej)- tibly attenuate, 'not quite two-fiftlis as long as the body, joints strongly obconi- cal, the intermediate nearly twice as long as wide, the third just visibly longer than the fourth. Prothorax scarcely one-half wider than long, the apex broadly, strongly arcuate, not quite continuous in curvature with the sides, the latter broadly, strongly arcuate and convergent anteriorly, becoming gradually feebly arcuate and nearly parallel near the basal angles, which are right and very slightly blunt ; base transverse, the sinuations small and rather strong, the median lobe subtruncate ; disk scarcely at all impressed, rather finely, deeply, excessively densely punctate and dull, the punctures polygonally crowded throughout. Elytra a little more than three times as long as the prothorax and about one-fifth wider, rather gradually ogival in apical third ; sides thence parallel and almost straight to the humeri, which are oblique externally but not exposed at base ; disk with very feebly impressed series of small but rather deep punctures, the intervals finely but strongly, extremely densely punctate. Ahdomen finely punctate, rather sparsely so except along the middle where the punctures become extremely dense. Legs long and slender, the basal joint of the hind tarsi distinctly longer than the remainder. Length 8.0 mm. ; width 3.2 mm. Arizona. I am not quite sure of the sex of the single individual before me, but it appears to be a male. The species is exceedingly distinct in 100 Coleopterological Notices, III. its larg-e size, unusually short, dense pubescence and excessively dense punctuation, not only of the pronotum, but also the elytra ; on the latter the serial punctures are not distinct, being obscured by the crowded punctuation of the intervals. The fourth joint of the maxillary palpi is normal, moderate in size, recti-triangular, the apex being' subequal in length to the outer side. This can hardly be the female of grandicoUis, as the dense punc- tuation along' the middle of the abdomen is always a male char- acteristic when it occurs in the allied Tenebrionidse. 17 H. exigUllS n. sp. — Oblong-oval, subparallel, rather convex, dark brownish-castaneous ; under surface, legs and antennae paler, more rufous ; integuments above rather dull, the pubescence short, very dense, conspicuous. Head small, less than one-half as wide as the prothorax ; clypeus and inter- ocular surface finely but not densely punctate, polished ; eyes large, separated by rather less than one-half their width ; antennae somewhat slender, about two-fifths as long as the body, joints five to ten moderately obconical, fully one-half longer than wide, three and four subequal, nearly cylindrical. Prothorax nearly three-fourths wider than long, the apex rather broadly but strongly arcuate, and almost perfectly continuous with the sides, the latter very broadly rounded anteriorly, becoming parallel and nearly straight only in basal third ; basal angles scarcely more than right, not noticeably rounded ; base transverse, the sinuations narrow but rather strong ; disk evenly convex, not impressed, rather finely, extremely densely punctate, the punctures rather shallow, arcuate anteriorly, rapidly shallow and evanescent at their posterior extremities, in mutual contact in a transverse direction, which gives to the punctuation a vague appearance of transverse rugulation under low power. Elytra a little more than three times as long as the prothorax, and, throughout basal two-thirds, equal in width to the latter, gradually ogival at apex ; sides parallel and barely perceptibly arcuate ; disk finely, very densely punctate, with fine, extre'mely feebly impressed striae which are just perceptibly punc- tate. Under surface shining, the abdomen finely, sparsely punctate. Legs moderate, the basal joint of the hind tarsi equal in length to the remainder. Length 4.0 mm. ; width 1.7 mm. Texas (El Paso). Mr. Dunn. A small and inconspicuous species, which is however not closely related to any other here described. It may be known at once by its exceptionally small size and large eyes. In the unique type the prosternum has been broken awa}^ at the sides, exposing the intercoxal process. This, viewed vertically upon its exposed surface, is well known to be longitudinally convex, strongly inflexed behind, arriving at the level of the prosternal side- Coleoj:i(erological Notices, III. 101 pieces at the hind margin. The exposure caused by the removal of the coxa, shows that this process is really a thin hoop, and, that below its surface, the cavities are almost confluent, being separated only by what appears to be a thin hyaline membrane ; the inner edge of the hoop is ciliate. 18 H. lielTinus n. sp. — Oblong-oval, subparallel, rather convex at the sides. Hatter above, pale rufo-testaceous throughout, the head and prothorax very sliglitly darker and more brownish ; lustre moderately shining ; pubes- cence short, rather sparse, pale but inconspicuous. Head finely, rather densely punctate anteriorly, more sparsely so toward base, the eyes in the male very large and separated by one-fourth of their own width ; autennse long and rather stout, distinctly longer than one-half the body, joints strongly obconi- cal, a little more serrate internally than externally, and fully twice as long as wide, third and fourth subequal in length. Prothorax large, two-fifths ^vider than long, the apex strongly arcuate and continuous in curvature with the sides, the latter broadly, strongly, nearly evenly arcuate throughout, the basal angles slightly obtuse but not rounded ; base transverse, strongly sinuate at each side of the middle; disk perfectly even, without impressions, convex, distinctly wider behind the middle than at base, finely, densely punctate, the punctures all distinctly separated. Elytra three times as long as the protho- rax, and, at the middle, equal in width to the disk of the letter ; apex gradu- ally, acutely ogival ; sides parallel and very feebly arcuate, the two bases exactly equal ; disk with very fine strife which are generally very feebly impressed, but more distinctly so toward the suture, the punctures of the series fine, approximate and sublinear ; intervals nearly flat, finely, rather densely and confusedly punctured. Abdomen somewhat coarsely but sparsely punctate, the prosternum densely so. Legs moderate in length, the femora robust, the posterior distinctly wider toward apex ; tarsi slender, the basal joint of the posterior slightly longer than the remainder. Length 5.8-G.3 mm. ; width 2.5 mm. Texas. National Museum. The specimens before me are males, and in this sex the last ven- tral segment is unimpressed, much longer than the fourth and strongly evenly rounded at apex. This is a comparatively isolated species, readily knovvn by the peculiar form of the prothorax, long antennse, very large eyes and robust femora, as well as by its peculiar pale ochreous coloration. The prothorax is more than ordinarily deflexed, the longitudinal con- vexity of th6 body l)eing therefore apparently greater than usual. 19 H. porosicornis n. sp. — Oblong-oval, subparallel, rather strongly convex, piceous-black above and beneath, the legs and antennfe slightly paler, rufoscent ; surface rather strongly shining, the pronotum finely, feebly 102 Coleoiolerological Notices, III. alutaceous ; pubescence coarse, short, pale ochreous but sparse and not very conspicuous. Head rather large, polished, the epistoma flat, the vertex strongly, abruptly, longitudinally convex, and finely, sparsely punctate ; eyes large, separated by one-fifth tlieir width in the male and two-fifths in the female ; antennae rather long and slender, two-fifths as long as the body in both sexes, feebly but distinctly attenuate, joints six to ten strongly obconical, the former a little less, the latter a little more than twice as long as wide, third distinctly longer than the fourth. Prothorax two-thirds wider than long, the apex broadly, strongly arcuate and continuous in curvature with the sides, the latter broadly, strongly arcuate anteriorly, parallel or very feebly convergent and feebly arcuate from the middle to the basal angles, which are slightly obtuse and very narrowly rounded ; base transverse, the sinuation at each side of the middle narrow but strong ; disk convex, not distinctly impressed, finely, rather densely punctate, the punctures round and separated by about their own diameters. Elytra fully three times as long as the prothorax and equal to the disk of the latter in width, gradually ogival at apex from slightly behind the middle ; sides parallel and nearly straight in basal three-fifths ; disk with very fine, feebly impressed series of fine but rather deep, close- set punctures, the intervals finely, confusedly and sparsely punctate. Abdomen finely, sparsely punctate. Legs moderate in length, rather robust, the basal joint of the hind tarsi subequal in length to tlie remainder. Length 6.4-7.5 mm. ; width 2.3-2.8 mm. Texas (El Paso). Mr. Dunn. A distinct species, somewhat resembling rotimdicollis, but much larger, more sparselj' punctate and with larger, more approximate eyes which differ sexually. The remarkable porous system of the antenna is extremely devel- oped in the present species. The pores are large and uniformly, rather sparsely distributed over the entire surface of the joints four to eleven ; they are circular, rather deep, quite independent of the hairs or bristles, and are filled with a peculiar white stellated mate- rial, of a spongy-pubescent nature, somewhat similar to the sensi- tive structure filling the pronotal foves in many pselaphides. This species approaches the genus Menoeceus, but the thoracic angles are not in the least prolonged posteriorly. 20 H, intermedins n. sp. — Oblong-oval, moderately convex, blackish- castaneous, the under surface and antennse rufo-fuscous ; legs paler and more flavate ; lustre rather shining, feebly alutaceous ; pubescence moderate in length, pale, somewhat dense, very easily removable. Head very small, rather coarsely and densely punctate, the eyes large, separated by about one- half their width ; antennje fully two-fifths as long as the body, rather robust, feebly attenuate, the intermediate joints strongly obconical and scarcely more than one-half longer than wide, the third slightly longer than the fourth. CoJeojjferological Notices, III. 103 Prolhnrar nearly three-fifths wider than long, the apex strongly arcuate and continuous with the sides, the latter hecoming parallel and distinctly arcuate toward base, the basal angles right, not distinctly jjlunt ; base transverse, the sinuations moderate ; disk very obsoletely impressed in the middle toward base, finely, deeply punctate, the punctures separated by scarcely their own widths, the interspaces rather strongly alutaceous. Elijtra fully three times as long as the prothorax and equal in width to the latter, rather abruptly ogival in apical third ; disk with feebly impressed series of small but distinct, not very approximate punctures, the intervals minutely and moderately closely punctured. ^Women minutely, very sparsely punctate, i^^s moderate ; basal joint of the hind tarsi almost two-fifths longer than the entire remainder. Length 5.5 mm. ; width 2.2 mm. Texas. Mr. W. Jiilich. The general form of the body recalls rotimdicoJIis, but the latter differs in its larger size, much smaller eyes and broader terminal joint of the palpi. In intermedius this joint is almost normal, recti- triangular, with the very oblique apex scarcely longer than the outer side. The head seems to be even unusually small. There is but little variation of any kind in the three specimens before me. 21 H. prolixilS n. sp. — Elongate, subparallel, moderately convex, aluta- ceous in lustre and rather dull, jjiceous to castaneous, the legs, abdomen and antennje paler and more rufous ; pubescence short, rather sparse and incon- spicuous. Head finely punctate, nearly evenly and rather densely so through- out ; eyes large, separated by one-third their width in the male, one-half in the female ; antennae long and slender, nearly one-half as long as the body, the joints strongly obcouical and much more than twice as long as wide, the third and fourth equal. Prothorax one-half wider than long, the apex and sides nearly as in occidentalis ; basal angles right and narrowly but very dis- tinctly rounded ; base transverse, the sinuations broad and strong, the median lobe broadly arcuate, projecting posteriorly as far as the basal angles ; disk scarcely impressed, finely, deeply, densely punctate, usually slightly more sparsely so toward base, the punctures anteriorly generally distinctly, some- times rather widely separated. Elytra fully four times as long as the protho- rax and very slightly wider tlian the latter, rather gradually, obtusely ogival at apex ; sides parallel and nearly straight, the humeri somewhat abruptly rounded to the prothorax ; disk with very feebly impressed series of fine but deep, close-set, sublinear punctures, the intervals finely, confusedly and rather sparsely punctate. Abdomen, under surface and legs nearly as in occidentalis. Length 8.5-9.7 mm. ; width 2.9-3.2 mm. New Mexico ; Arizona. This species is somewhat related to occidentalis, but differs in several characters to a decisive degree. The punctuation of the 104 Coleopterological Notices, III. pronotnm in proUxus is much finer and less dense, and the eljtral punctures are decidedly sparser ; the antennae are more slender, with the joints more elongate, the comparisons being made from the male ; the base of the prothorax is scarcely at all oblique toward the angles, and finally, the two sexes are similar in size and form, while in occidentalis the male is notably more slender than the female and with a less transverse prothorax. The maxillary palpi are nearly as in occidentalis, but the fourth joint is rather narrower. I have seen six specimens. Mr. Champion Avrites me that this species is rather closely allied to dm-angoensis, but is distinct. 22 H. occidentalis Champ. — Biol. Cent.-Araer., Coleopt., IV, Pt. i, p. 425. — Rather elongate, parallel, moderately convex, dull and alutaceous, castaneous, the legs and under surface rather paler, rufescent ; pubescence short, rather fine, moderately dense, not at all conspicuous. Head finely, densely punctate anteriorly, more coarsely and slightly more sparsely so between the eyes, which are large, separated by one-third their width in the male and one-half in the female ; antennse about two-fifths as long as the body, subfiliform, moderately stout, the joints about twice as long as wide, third .slightly longer than the fourth. Prothorax one third (male) to one-half (female) wider than long, the apex broadly, rather feebly arcuate, three- fourths as wide as the base, not continuous in curvature with the sides, the latter parallel and nearly straight in basal half, thence moderately convergent and arcuate to the apex ; basal angles right, slightly blunt; base posteriorly oblique toward the basal angles, broadly, feebly arcuate in middle half; disk scarcely impressed, rather coarsely, very densely punctate, the punctures almost in contact but circular and not i)olygonally crowded. Elytra three and one-half times as long as the prothorax and very slightly wider, gradually, obtusely ogival toward apex ; sides thence parallel and nearly straight to the humeri, wliich are obliquely, broadly rounded externally to the prothorax ; disk with rather broadly, feebly impressed series of small, close-set punctures, the intervals finely, confusedly and moderately closely punctured. Abdomen polished, finely, sparsely punctured, a little more closely so along the middle in the male. Legs decidedly robust, the basal joint of the hind tarsi much longer than the remainder. Length 10.0-11.0 mm. ; width 3.3-3.8 mm. Texas. The fourth joint of the maxillary palpi is strongly dilated, with the apex much longer than either side, and, in outline, is nearly as in Lobopoda. The large size and elongate-parallel form will readily serve to differentiate this species from any other within our faunal limits, being approached in these respects only by proliccus. Coleojjterological Notices, III. 105 23 H. dorsalis Schz.— Proc. Am. Phil. Soc, XVII, p. 370.— Oblong-oval, rather strongly dt-pressed, dark rnfo-ferruginous, the elytra black in apical two-thirds; abdomen, legs and antennje paler; surface moderately shining, feebly aliitaceous ; pubescence short, rather fine and sparse, pale but not con- spicuous. Head ratlier sparsely, coarsely punctate, the eyes large, somewhat narrowly rounded within, separated in both sexes by one-third to one-fourth their own width ; antenuse long, slender, filiform, fully three-fifths as long as the body in the male, joints almost parallel, much more than twice as long as wide, third much shorter than the fourth in the male, subequal in tlie female. Prothorax three-fifths wider than long, the apex strongly arcuate and continuous with the sides, the latter broadly arcuate toward the base, which is transverse, with the sinuations small and feeble ; angles right in the male, somewhat obtuse in the female, not rounded ; disk widest at about basal tliird, coarsely and rather sparsely punctate, feebly deplanate toward the basal angles in the female, very obsoletely impressed in the middle toward base. E/i/tra a little more than three times as long as the prothorax and very slightly wider, gradually ogival at apex ; sides parallel and almost straight in basal three- fifths, the humeri slightly exposed : disk witli feebly impressed series of exceedingly fine, scarcely distinguishable, not very close-set punctures, the intervals finely, sparsely punctate, the punctures not distinctly finer than those of the striae. Abdomen finely but distinctly, rather sparsely punctate. Legs slender, the basal joint of the hind tarsi fully one-third longer than the remainder. Length 5.7 mm. ; width 2.2-2.3 mm. Florida (Tampa and Capron). Mr. Sehwarz. A widely isolated species, not only in coloration l)ut in its long filiforni male antenna, large eyes and peculiarly small inconspicuous serial punctures. The male antennsB, with" the third joint shorter than the fourth, differ from those of any other species belonging to the present group which I have seen. In the female the antenna? are shorter and stouter. The fifth segment in the male is much shorter and more obtusely rounded than in the female, and, in both sexes, the lateral subapical emarginations of this segment are unusually strong. The sexual difference in the eyes is not marked ; in fact in the single female before me they are, if anything, more narrowly separated than in the male. The fourth joint of the maxillary palpi is ver}' broad, the apex a little longer than either side, and the angle at the base slightly more than right. 24 H. discretus n. sp. — Oblong, subparallel, moderately convex, pice- ous-black ; under surface, legs and antennae slightly paler, dark rufo-ferrugi- nous, the abdomen distinctly paler toward apex; pronotum alutaceous, the elytra polished ; pubescence rather long, semi-erect, somewhat coarse, pale Annals N. Y, Acad. Sci., VI, Nov. 1891.— 8 106 Coleopterological Notices, III. and sparse. Head rather strongly, sparsely punctate, the eyes large, separated by two-fifths their width ; antennae stout, two-fifths as long as the body, feebly attenuate toward apex, joints four to eleven very slightly increasing in length, the sixth joint on the compressed side fully one-half longer than wide, obconi- cal, the tenth twice as long as wide, third and fourth equal in length. Pro- thorax three-fourths wider than long, the apex broadly arcuate and continuous with the sides, the latter broadly, feebly arcuate and convergent anteriorly, more strongly arcuate toward the basal angles, which are slightly obtuse but scarcely noticeably blunt ; base transverse, the median lobe small and short, rounded ; disk quite distinctly wider at basal third than at base, scarcely at all impressed, broadly explanate laterally toward the basal angles and narrowly, feebly reflexed along the sides in their vicinity, coarsely, strongly punctate throughout, the punctures circular and generally separated by nearly their own diameters. Eli/tra equal in width to the prothorax and about three and one-half times as long, gradually, rather acutely ogival at apex ; sides parallel and nearly straight in basal two-thirds ; disk with feebly impressed series of rather small but distinct punctures, the intervals finely, rather sj^arsely, confusedly punctured. Abdomen finely but rather strongly, sparsely punctured, almost totally impunctate toward apex ; metasternum ratlier coarsely, sparsely punctate externally, rapidly very finely, densely so toward the middle ; prosternum densely punctured. Legs rather long, the femora robust ; basal joint of the hind tarsi two-fifths longer than the remain- der. Length 6.2-7.4 mm. ; width 2.4-3.1 mm. Massachusetts; New York. The general form throughout recalls that of fusicornis, and, as in that species, the antenme are notably robust, at least in the female, and attenuated, but here the resemblance altogether ceases. In pronotal punctuation the two species stand almost at the extremes of the genus in regard to the magnitude of the punctures, and the basal joint of the hind tarsi is conspicuously longer in discretus. The description is taken from the female. The male is smaller, with entirely polished upper surface, the eyes separated by about one-fourth of their width, and the antenuiE more slender and much longer, being a little more than one-half as long as the body. The pubescence, also, seems to be a little longer, and the elytral punc- tuation is decidedly sparser ; the pronotum is not so decidedly ex- planate toward the basal angles. In both sexes the fourth joint of the maxillary palpi is rather strongly dilated, triangular, with the apex a little longer than the outer side. The fifth elytral stria is more strongly impressed toward base. 25 H. convexus n. sp. — Elliptical, strongly convex, black above, the under surface piceous-black ; legs and antennae throughout dark rufo-ferrugi- Coh'opterological Notices, IIL lOY nous ; pubescence slioi-t, rather coarse, pale but sparse and not very conspicu- ous. Head rather strongly but sparsely punctured between the eyes, the latter large and separated by about one-half their width in both sexes ; antennae long and fililorui, one-half as long as the body, the joints extremely feebly obconical, twice as long as wide, the third scarcely perceptibly longer than the fourth. Protliorax fully one-half wider than long, the apex distinctly, broadly arcuate, scarcely more than one-half as wide as the base, not con- tinuous in curvature with the sides, the apical angles being very obtuse and rounded ; base transverse, the narrow sinuation at each side of the middle rather strong ; sides more or less convergent from the basal angles, sometimes parallel in basal half, nearly straight, broadly rounded anteriorly ; basal angles right, not rounded ; disk very feebly impressed in the middle toward base, coarsely, deeply, moderately densely punctured, the punctures generally very narrowly separated, the interstices feebly alutaceous, the middle toward base and region of the basal fovese generally more or less impunctate. Eli/tra a little less than three times as long as the prothoi-ax, and, at the middle, scarcely one-fourth wider, the apex gradually acute ; sides arcuate and nearly continuous with those of the protliorax ; disk coarsely, deeply striate, the stri;e coarsely, deeply and approximately punctate, the intervals moderately convex, highly polished, rather finely, sparsely punctured. Under surface finely, sparsely punctate, the prosternum densely so, the propleurEe very sparsely throughout. Legs rather long, the basal joint of the hind tarsi slightly longer than the remainder. Length 6.8-7.5 mm. ; width 2.8-3.2 mm. Florida (Key West); Texas. Mr. Jiilich. A remarkably distinct species, apparently inhabiting- the same regions as denaus; in outline somewhat similar to that species but much larger, more shining, more coarsely, sparsely punctate and pubescent, and with very much longer antennae. The eyes in the ample series before me, do not vary measurably in the interval separating them, which is much less than in densus. 26 H. deilSllS Lee— N. Spec. Col., 1866, p. 138.— Elongate-elliptical, rather strongly convex, generally dark rufo-ferruginous, with the elytra, abdomen and antennae, except toward base, piceous-black ; anterior parts generally dull, the elytra more shining ; pubescence short, coarse, pale, dense and conspicuous. Head moderate, the interocular surface rather coarsely and somewhat sparsely punctured ; eyes large and convex, separated in both sexes by about two-thirds their width ; antennae stout, one-third as long as the body, joints four to ten very strongly obconical, slightly longer than wide, more serrate internally than externally, third slender, slightly longer than the fourth. Prothorax scarcely one-half wider than long, the apex rather strongly arcuate and continuous in curvature with the sides, the latter becoming less arcuate and very feebly divergent toward the basal angles, which are right and not at all rounded ; base transverse, narrowly and rather strongly sinuate on each side of the short truncate median lobe ; disk almost unimpressed 108 Coleojitei^oloriical Notices, III. throughout, rather coarsely, deeply punctate, the punctures round, perforate and generally very narrowly separated, the interstices dull, a narrow imper- fect median line sometimes impunctate toward base.

Under surface polished, finely, sparsely punctate, the prosternum more densely, coarsely so but not dull. Legs moderate, the posterior tarsi rather robust, with the basal joint a little shorter than the remainder. Length 5.0-6.0 mm. ; width 2.0-2.4 mm. Florida ; Texas ; Ohio. The color is frequently piceous-black throughout above, the legs always remaining pale. Tlie eyes in sixteen of the seventeen speci- mens before me are perfectly uniform, and sejiarated by two-thirds of their own width, but in the remaining specimen, which appa- rently does not differ in any other particular, they are smaller and separated by their full width; this specimen singularly enough is a male, and must be regarded as an accidental aberration. A few specimens in the cabinet of Mr. Jiilich are labeled Ohio, and are said to have been collected by Mr. Dury. 27 H. rulicollis Champ. — Biol. Cent.-Amer., Coleopt., IV, Pt. i, p. 438. — Elongate-oval, moderately convex, dull ; elytra and abdomen blackish, remainder dark rufo-ferruginous ; antennse and legs concolorous ; pubescence rather short and coarse, very dense, i^ale, and, on the elytra, rather conspicu- ous. Head moderate, rather strongly, very densely punctate and dull ; eyes small, separated by distinctly more than their width ; antennse moderately stout, nearly two-fifths as long as the body, intermediate joints nearly one- half longer than wide, third and fourth subequal. Prothorax one-half wider than long ; apex broadly, distinctly arcuate, about three-fourths as wide as the base, the latter transverse, the sinuations narrow and feeble ; sides broadly arcuate, usually more or less parallel from the basal angles and then more strongly rounded into the apex ; basal angles right, not rounded ; disk not at all impressed, rather strongly, excessively densely punctured and completely dull, the basal fovesB obsolete. Elytra three times as long as the prothorax, and, at the middle, nearly one-third wider, rather gradually and acutely ogival at apex ; sides feebly arcuate, generally continuous with those of the prothorax ; disk finely, rather feebly, very densely punctate, the interstices very minutely, strongly granulato-reticulate and alutaceous, the striae ex- tremely fine, feebly impressed and very finely, inconspicuously punctured. Under surface punctured nearly as in punctatissimus. Posterior tarsi very short, the basal joint much shorter than the remainder. Length 4.7—5.8 mm. ; width 2.0-2.2 mm. GoleoiAerological Notices, III. 109 Arizona. Mr. Morrison. A small, densely punctate and unusually dull form, rather closely allied to densus and perfectly similar to the latter in the ])eculiar coloration of the body, but difi'criufi- in its much liner, still denser punctuation, smaller eyes, and in its decidedly more depressed form. 28 H. dissensilS n. sp. — Oval, moderately robust, rather convex, casta- neons ; legs and antennae pale, flavo-testaceous ; lustre somevphat alutaceous, tli(f elytra more strongly shining, pubescence moderate in length and density, l).ib;. Head densely, rather finely punctate, the punctures generally in mutual contact ; eyes small, separated by nearly one-third more than their own width ; antenuje moderately stout, filiform, two-fifths as long as the body, the joints feebly obconical and about one-lialf longer than wide, third slightly longer than the fourth. Protliorax rather elongate, scarcely more than two-fifths wider than long, the apex broadly arcuate and almost continuous with the sides, the latter broadly rounded anteriorly, very feebly arcuate and ])arallel toward base, the basal angles slightly obtuse and very slightly rounded ; base transverse, the sinuations just perceptible ; disk evenly convex, rather coarsely, very deeply punctate, the punctures round, separated by rather less than their own widths, the bottom of each highly polished, the interspaces strongly alutaceous and granulato-reticulate. Ehjtra scarcely two and one- half times as long as the jjrothorax, and, at the middle, but slightly wider; apex souiewhat gradually acute ; sides broadly arcuate, nearly continuous with those of the prothorax ; disk with moderately impressed series of vei-y coarse, deep, perforate and approximate punctures, the intervals nearly flat, froui three to four times as wide as the strial punctures, minutely, feebly, confusedly and somewhat closely punctured. Abdomen rather sparsely but unusually strongly punctured ; anterior parts of the body coarsely so. Legs unusually short and robust. Length 4.4-4.8 mm. ; width 1.9-2.1 mm. Texas (Galveston). A distinct species, easily recognizable by its small size, oval, con- vex form, coarse punctuation especially of the elytral series, and rather long prothorax. It does not appear to be especially related to any of the Mexican species of the Biologia, but belongs near densus. 29 H. seriatllS n. sp. — Oblong-ovate, slightly wider behind, moderately convex, dark piceo-castaneous, the pronotum and elytral suture sometimes feebly rufescent ; under surface and legs paler, rufous ; pubescence moderate in length, rather coarse and sparse. Head moderately convex, rather finely but deeply punctate, the punctures between the eyes separated by about their own diameters, the eyes moderate, separated by very nearly tluur own width in both sexes ; antenme long, slender and filiform, three-fifths as long as the body, joints four to eleven subequal, feebly obconical, the intermediate rather more than twice as long as wide, the third three times as long as wide and distinctly longer than the fourth. Prutliorax rathei' small, two-thirds wider 110 CoJeopterological Notices, III. than long, the apex broadly, rather strongly arcuate, the apical angles broadly rounded, the sides gradually more feebly divergent toward base and becoming nearly parallel in basal third, the angles right, not rounded ; base transverse, the sinuations broad and very feeble ; disk hardly at all impressed, somewhat coarsely, deeply punctate, the punctures round and generally separated by nearly one-half their own diameters, the interspaces shining. Elytra dis- tinctly more than three times as long as the prothorax, and, behind the middle, one-third wider, rather abruptly and obtusely ogival at apex, the sides rather strongly arcuate behind, almost continuous with those of the prothorax, with distinctly impressed series of coarse close-set perforate punc- tures, the intervals polished, nearly Hat, finely and sparsely punctate. Abdo- men finely, very sparsely but rather strongly punctate, the prosternum densely so, the propleurse very sparsely. Legs slender, the basal joint of the hind tarsi equal in length to the remainder. Length 5.5 mm.; width 2.4-2.6 mm. Arizona. The peculiar form of tliis species — distinctly widest behind, — top-ether with the long antennas and coarsely perforate elytral striae, will readily serve to distinguish it. It belongs near densus, and has the coarse punctuation of the pronotum characterizing that and some allied species, but the form is here rather less convex ; it is also allied to the Mexican pallidus Champ., but is darker in color, and has the pronotal punctuation less dense and not rugulose. Five specimens, which are extremely uniform among themselves in size and outline ; some are entirely pale testaceous from imma- turity. 30 H, testacetIS u. sp. — Elliptical, rather strongly convex, pale rufo- testaceous throughout, strongly shining ; pubescence moderate in length, pale but sparse and not conspicuous. Head rather coarsely, deeply and sparsely punctate ; eyes large, separated by one-half their width in the male and two- thirds in the female ; antennse rather slender and filiform, two-fifths as long as the body, the joints moderately obconical, the intermediate about twice as long as wide, third and fourth equal. Prothorax nearly three-fourths wider than long, the apex narrowly, strongly arcuate and continuous with the sides, which are strongly oblique and feebly arcuate anteriorly, more strongly arcuate in basal two-fifths, becoming very feebly convergent toward the basal angles, the latter right and slightly blunt ; base transverse, the median lobe small, short, rounded ; disk scarcely at all impressed, coarsely, deeply, rather sparsely punctate, the punctures generally separated by nearly their own diameters, the interspaces highly polished. Elytra but slightly more than three times as long as the prothorax, and, at the middle, very slightly wider, gradually, rather acutely ogival in apical two-fifths, the sides parallel and feebly arcuate, the two bases exactly equal ; disk with fine but distinctly impressed series of fine but deep and distinct punctures, which are noticeably linear, the intervals feebly convex, polished, finely but distinctly, sparsely punctate. Abdomen CoJeoptei'ological Notices, III. Ill minutely, feebly, sparsely punctate. Ler/s rather slender, the femora moder- ately robust ; liasal joint of the hind tarsi slender, at least one-third longer than the remainder. Length 6.0 nnu. ; width 2.6-2,8 mm. Arizona. This distinct species is somewliat similar to helviiiKS in outline, and in its pale color and rather more tlian ordinarly deflexed pro- notum, which gives it a relatively strong longitudinal convexity. It differs conspicuously from helmnus in its very coarse, sparse pronotal punctuation, smaller eyes, much less robust femora and shorter, more slender antennae. It is represented by four specimens. 31 H. rotuildicollis n. sp. — Oblong-oval, rather strongly convex, piceous-black througliout, the legs and antennae but slightly paler, rufescent, rather strongly shining, the pubescence moderately long and dense, very easily denuded. Head feebly convex, finely and somewhat densely punctate, the punctures distinctly separated ; eyes moderate, separated by about their own M'idth ; antennse moderately stout, filiform, scarcely one-half as long as the body, the joints distinctly obconical, twice as long as wide, the third and fourth equal. Prothorax large, three-fifths wider than long, the apex very strongly, rather narrowly arcuate and continuous with the sides, the latter parallel and nearly straight in a little more than basal third ; base transverse, the median lobe short, broadly rounded, distinct; liasal angles right and slightly blunt ; disk feebly explanate near the sides toward base, more especially in the female, not distinctly impressed, rather finely but strongly, somewhat sparsely punctate, the punctures separated by scarcely their own widths, the interspaces strongly shining. Elijlra rather distinctly more than three times as long as the prothorax, gradually ogival in apical two-fifths ; sides parallel and straight in basal three-fifths ; disk scarcely equal in widtli to the prothorax, with feebly impressed series of small but deep, brevilinear, not very close-set punctures, the intervals minutely, confusedly and moder- ately closely punctured. Ahdomen finely, very feebly and sparsely punctate. Legs rather slender. Length 5.6-6.4 mm. ; widtli 2.1-2.6 nmi. Arizona. In the four specimens before me there is not one entire posterior tarsus, but the basal joint is slender and appears to be slightly longer than the remainder. The fourth joint of the maxillary palpi is strongly dilated, as much so as in Lobopoda, the angle at the point of support being distinctly obtuse, and the apex much longer than either side and rather widely open and spongiose throughout its extent. The strongly arcuate apex of the prothorax, rather sparse punc- tuation of the pronotum and palpal structure, will readily serve to identify this distinct species. The Central American emmenasto- 112 Coleopferological Notices, III. ides is somewhat allied, but differs in its much more oval form and smaller prothorax. 32 H, illC|llilillIlS n. sp. — Oljlong-oval, moderately convex, rufo-testa- ceous, the elytra still paler and more flavate ; upper surface polished, the pronotum feebly aliitaceous ; pubescence rather sparse, semi-erect, coarse, flavate in color. Head decidedly largje, strongly, longitudinally convex, minutely, excessively sparsely punctate, the epistoma abruptly flat and more closely hut still sparsely punctate ; eyes small, separated by distinctly more than their own width ; antennre stout, cylindrical, nearly one-half as long as the body, distinctly attenuate, the joints obconical, third and fourth equal. Prothorax short, twice as wide as long, the apex subtruncate, just visibly arcuate, three-fourths as wide as the base, the latter broadly arcuate in the middle, the lobe extending posteriorly fully as far as the angles; sinuations extremely feeble ; basal angles right ; sides broadly arcuate throughout, a little more convergent anteriorly ; disk slightly wider behind the middle than at base, feebly explanate near the sides toward base, not distinctly impressed or foveate, very finely, densely punctate, the punctures distinctly separated. Elytra fully three times as long as the prothorax, and, throughout, slightly narrower than the disk of the latter, distinctly dehiscent in apical third, the two bases exactly equal ; sides parallel and nearly straight, the apex some- "what obtusely ogival ; disk rather finely, moderately closely punctate, with- out trace of impressed lines except the sutural, which is very feeble, without trcice of punctured series except extremely indefinitely toward base. Ahdo- vien finely, moderately closely punctate, the fifth segment almost completely impunctate. Legs short and very robust, the tarsi short ; basal joint of the posterior as long as the remainder. Length 4.5 mm. ; width 1.8 mm. California. The single specimen before me is a male, and differs so greatly from the usual forms in general appearance, that for a long time I thought that it would have to be considered the type of a distinct genus; but, on close examination, no character of any kind can be discerned by which to distinguish it from Hymenorus. The maxillary palpi are of the usual form, and the lateral sub- apical emarginations of the fiftii ventral segment are deep and dis- tinct. The claws are rather short and stout and finely, closely pectinate nearly throughout the length. This species is said to be myrmecophilous. 33 H. fusicornis n. sp. — Oblong, parallel, rather robust and feebly convex, piueous above, the elytra black ; under surface and antenuie dark piceo-castaneous, the legs paler and more flavate ; lustre rather shining, the pubescence somewhat dark, fine and sparse, rather long, subrecumbent.

Prothorax tliree-fourths wider than long, the apex broadly, moderately arcuate, three-fourths as wide as the base, the latter broadly, strongly arcuate or feebly lobed in the middle, transverse toward the basal angles, which are slightly obtuse but not distinctly rounded ; sides broadly, evenly arcuate throughout ; disk slightly widest at basal third, very feebly impressed in the middle near the base, very finely and rather sparsely punctate. Elytra but little more than three times as long as the prothorax and equal in width to the disk of the latter, rather abruptly but acutely ogival in apical third ; sides parallel and straight ; disk with very feebly impressed series of unusually fine and feeble punctures, the intervals still more minutely and sparsely punctate.

Legs moderate, normal, the basal joint of the hind tarsi but slightly longer than the remainder. Length 6.8 mm. ; width 2.8 mm. California (southern). A remarkably isolated species, to be readily identified by its smooth, rather shining, minutely, sparsely punctate surface and robust, compressed and rapidly finely attenuate antennte; the pro- notum is unusually deplanate along- the base to the basal angles, but strongly declivous thence anteriorly along the sides. T have seen but a single specimen which is a female. The so- called sixth segment is about one-fifth as wide as the fifth, truncate at apex, with the angles rounded. This species appears to approach the genus Menceceus, but the posterior angles of the prothorax do not exhibit the slightest ten- dency to prolongation backward. 34 H. nitidipenilis n. sp. — Oblong-elongate, parallel, subdepressed, dark piceo-castaneous above, the under surface, legs and antennae pale rufo- testaeeous ; elytral suture narrowly rufescent ; prothorax rather dull, the elytra strongly shining ; pubescence very short, rather sparse, inconspicuous. Head rather coarsely punctate, sparsely so between the eyes, the latter moder- ate in size, separated by nearly three- fourths of their width ; antennae long, somewhat stout, fully one-half as long as the body, the joints gradually nar- rower and shorter toward apex, the intermediate extremely feebly obconical and distinctly more than twice as long as wide, the third and fourth equal. Prothorax a little more than one-half wider than long, the apex rather strongly arcuate and continuous with the sides, which are broadly arcuate anteriorly, becoming nearly parallel and straight only very near the base, the basal angles right, not rounded ; base transverse, the sinuations rather broad, moderately 114 Coleopterological Notices, III. distinct ; disk scarcely impressed, somewhat coarsely, very densely punctate, tlie punctures circular and almost absolutely in contact, but not polygonally crowded.

Abdomen finely, sparsely punctate. Legs slender, the basal joint of the hind tarsi distinctly longer than the remainder. Length 6.8 mm. ; width 2.3 mm. Arizona. This species is not at all closely related to any other, the strongly shining, deeply striate, minutely punctate elytra, coarsely, densely punctate pronotum, long antennte and oblong, subdepressed form, at once distinguishing it. 35 H. inaeqiialis n. sp. — Oblong, parallel, strongly convex, the elytra polished, dark piceo-castaneous, the under surface, legs and antennse paler, rufescent ; pubescence rather long, more than usually erect, not very dense.

Prothorax short, three-fourths wider than long, the apex two-thirds as wide as the base, almost transversely truncate, the base transveise, the median portion broadly, distinctly arcuate ; sides broadly arcuate and strongly convergent anteriorly, very slightly convergent and nearly straight in basal two-fifths, the angles rather distinctly obtuse but not at all rounded ; disk not impressed, convex, very coarsely, extremely densely and not very deeply punctate, the punctures in contact and somewhat poly- gonally crowded. Elytra nearly four times as long as the prothorax and just perceptibly wider, the apex gradually, evenly ogival, the humeri feebly, obliquely rounded externally to the prothoracic base, the sides parallel and nearly straight; disk with extremely feebly impressed series of small but deep, close-set and almost perforate punctures, which are slightly oblong; intervals highly polished, minutely, sparsely punctate. Abdomen minutely, sparsely punctate, the anterior portions of the body coarsely so, the prosternum and propleurse extremely densely so. Legs moderate in length, rather densely pubescent, the femora slightly robust ; basal joint of the hind tarsi subequal in length to the remainder. Length 7.0 mm. ; width 2.8 mm. Arizona. A distinct and comparatively isolated species, distinguishable by its oblong, unusually convex form, very coarse, dense prouotal and Coleopterological Notices, III. 115 minute, sparse el^'tral punctuation and rather long, unusually erect and fulvous pubescence, the latter being quite conspicuous although rather sparse on the elytra. The unique type is a female. 36 H. tenellllS n. sp. — Slender, subparallel, rather convex, dark rufo- testaceous throughout, the abdomen becoming slightly piceous toward the sides and apex; anterior parts rather dull, the elytra shining; pubescence short, coarse, pale fulvous, moderately dense and distinct. Head rather coarsely, very densely punctate and dull, the eyes rather large, separated by about three-fourths their width ; antennae somewhat slender, two-fifths as long as the body, the joints feebly obconical and about three-fourths longer than wide, third slightly longer than the fourth.

Elytra nearly three times as long as the prothorax, and, throughout, scarcely perceptibly wider, the sides parallel and straight to apical third, the apex ogival ; disk finely, rather sparsely punctured, with series of very fine incon- spicuous punctures, the series rather distinctly impressed near the suture but becoming almost completely unimpressed laterally. Under surface very finely, sparsely punctured, the presternum and propleuras finely, extremely densely so but not dull. Length 4.8-5.0 mm. ; width 1.8 mm. Florida (Crescent City). Mr. Schwarz. A small subparallel species, somewhat related to densus, but differing greatly in form, structure of the antennie, coloration and elytral punctuation. I have seen three specimens, which do not display any variation sexual or otherwise. 37 H. SObrinus n. sp. — Oblong-oval, convex, shining, black throughout above and beneath ; legs black, the femora slightly rufescent toward base ; antennce fuscous ; pubescence moderately long, not extremely dense and not very conspicuous. Head between the eyes rather coarsely, deeply punctate, the punctures slightly separated ; eyes moderate, separated by fully their own width ; antennae rather slender, two-fifths as long as the body, the intermediate joints very feebly obconical and nearly twice as long as wide, third and fourth mutually similar, slender, cylindrical, the former slightly the longer.

Under surface polished, minutely, sparsely punctate, the prosternum very densely so but not dull. Legs moderate. Length 4.8 mm. ; width 2.0 mm. Florida. This species belongs somewhat near teneUus, but differs greatly in coloration, in its broader form, and especially in its wider elytra and more transverse prothorax ; the eyes in the unique female are decidedly smaller, and the antennae still more slender. 38 H. floridaims n. sp. — Oblong-oval, rather strongly convex, dark piceous-brown throughout, tlie legs and antennse throughout pale rufo-ferru- ginous ; pubescence short, rather fine, sparse, pale but not very conspicuous.

In its oblong- form, with the elytra rather short, parallel and slightly wider than the prothorax, this species is an analogue of sobrinus and fioiHdanua, but it differs from both of the latter in its finer, much denser punctuation, more elongate prothorax and slightl}^ shorter, more robust antenna). 40 H. ftisctllllS n. sp. — Oblong, rather elongate and convex, dark brown- ish-piceous, the under surface and legs slightly paler, rufescent; integuments feebly shining, the pubescence very short, pale, dense and conspicuous. Head finely, densely j)unctate, the punctures rather distinctly separated between the eyes, the latter somewhat large, separated by fully three-fourths their width ; antenn;e rather more than one-third as long as the body, somewhat slender, the joints feebly obconical, nearly two-thirds longer than wide, the third slender, much longer than the fourth. Prothorax one-half wider than long ; apex feebly arcuate, two-thirds as wide as the base, not at all continu- ous with the sides, the apical angles being distinctly evident although very obtuse; base transverse, the sinuations small and very feeble ; basal angles a little more than right, not rounded ; sides broadly arcuate and convergent anteriorly, feebly arcuate toward base ; disk just visibly wider behind the middle than at base, scarcely at all impressed, rather finely, extremely densely punctate.

Abdomen 118 Coleopterological Notices, III. finely, sparsely punctate, otherwise nearly as in conferUis, the metasternum a little more sparsely punctate. Legs slender ; basal joint of the hind tai-si distinctly longer than the remainder. Length 5.8-6.6 nun. ; width 2.3—2.6 mm. California (Coronado Beach, San Diego Co.). Dr. Blaisdell. This species is allied to confertus, but differs in its larger size, more elongate form, more slender antennae and longer basal joint of the hind tarsi. The prothorax, especially, is longer and with the apex more transverse. I have not positively identified the sexes in the two individuals before me, but it is probable that the sexual difference in the eyes is not marked. 41 H. inacer n. sp. — Oblong-oval, somewhat convex, rather shining, pale rufo-testaceous, sometimes slightly brownish, the legs more flavate ; pubescence very short, dense, pale, moderately conspicuous. Head feebly convex, the interocular surface finely, rather sparsely punctate in the male, the eyes in that sex moderately large, separated by fully three-fourths of their width ; antennae stout, distinctly more than one-third as long as the body, very feebly attenuate, the intermediate joints short, scarcely one-fourth longer than wide, strongly obconical, the third more slender and scarcely perceptibly longer than the fourth. Prothorax about one-half wider than long, the apex two- thirds as wide as the base, feebly arcuate ; sides broadly arcuate and conver- gent anteriorly, nearly parallel and very feebly arcuate toward base, the angles slightly obtuse ; base transverse, the sinuations small and feeble ; disk broadly, just visibly impressed in the middle toward base, rather finely, extremely densely punctate, the punctures in contact and sometimes slightly rugulose, the lustre however rather shining. Elytra fully three times as long as the prothorax and just visibly wider, the apex gradually ogival, the humeri narrowly exposed, rounded ; sides parallel and almost straight in basal two- thirds ; disk with vei-y fine, feebly impressed striae of fine, inconspicuous punctures, the intervals rather strongly shining, nearly flat, finely, extremely densely, confusedly punctate. Under surface finely, sparsely punctate, the prosternum and its side-pieces very densely so. Legs rather slender, the basal joint of the hind tarsi nearly as long as the remainder. Length 5.0-5.8 mm. ; width 2.0-2.2 mm. California (Poway, San Diego Co.; Folsom). A rather inconspicuous, unusually pale species, somewhat dis- tantly related to deplanatus and distinguishable by its much more convex form and slightly longer prothorax. In deplanatus the punctures of the pronotum are small, circular and distinctly separated, while in the present species they are quite peculiar, giving under small magnifying power, the rugulose appear- ance mentioned in the description. The punctures in macer are much larger than in deplanatus, slightly elongate, closely crowded Coleopterological Notices, III. 119 and polygonal, much shallower and g-radually evanescent toward their posterior extremities, with the bottom polished, the hair borne from a minute tuberculiform puncture adjoining- the anterior margin of each. Five specimens, two of which were sent me by Dr. Blaisdell, of San Diego. 42 H. indlltus n. sp. — Oblong-elongate, parallel, rather strongly convex, dull, piceous in color, the legs and antenuje slightly paler and more ferrugi- nous ; pubescence short, extremely dense. Head feebly convex, the punctures between the eyes moderately fine and distinctly separated ; eyes moderate, separated by a little more than three-fourths of their width ; antennae rather stout, not perceptibly attenuate, somewhat long, about two-fifths as long as the body, the intermediate joints strongly obconical, about one-third longer than wide, the third cylindrical and just visibly longer than the fourth. Prothorax slightly more than one-third wider than long, the apex broadly arcuate, nearly three-fourths as wide as the base, the latter transverse, the sinuations narrow but distinct; sides broadly rounded anteriorly, becoming nearly straight and parallel in basal half, the angles right, not at all rounded ; disk convex, finely, deeply, very densely punctured, the punctures round and slightly separated toward the middle. Elytra three times as long as the pro- thorax and very slightly wider, rather obtusely ogival at apex, the humeri slightly rounded to the base of the prothorax ; sides parallel and nearly straight in basal two-thirds ; disk finely, extremely feebly striate, the striae finely and inconspicuously punctured ; intervals very finely and excessively densely punctate. Abdomen polished, minutely, rather sjjarsely punctured ; prosternum and pro2)leur?e rather coarsely, extremely densely so. Legs moderate, the basal joint of the hind tarsi slightly shorter than the re- mainder. Length 5.0— 7.0 mm. ; width 1.9-2.5 mm. Texas (El Paso) ; New Mexico ; Arizona. The large amount of material before me is rather heterogeneous and apparently involves two or three very closely allied species. Some of the smallest forms are females, and two are labeled "Florida," but this is probably an erroneous locality. The typical form is from El Paso, and has the punctuation of the pronotum as described above and the pubescence rather dark in color. Other specimens have the punctuation of this part slightly coarser, densely crowded, polygonal and more rugulose, the pubes- cence being a little longer, pale ochreous and much more conspicuous. All the specimens agree, however, in the extremely dense punctua- tion of the elytra, which noticeably exceeds that of deplanatus, and is even apparently denser than in macer. The species is allied to 120 Coleopierological Notices, III. macer, but differs in its more elongate form, especially longer pro- thorax, larger size and darker color. In some specimens, especially those with paler pubescence, there is scarcely a trace of the serial punctures. 43 fl. punctatissimus Lee— New Spec. Col., 1866, p. 138. — Oblong- oval, siibparallel, somewhat depressed, pale brown and dull above, paler ruf'o- testaceous and polished beneath ; legs and antennae still paler, more flavate ; pubescence extremely dense, short. Head feebly convex, rather finely, densely punctate, the punctures distinctly separated between the eyes, tlie latter moderately large, separated by three-fourths their width ; antennae stout, rather more than one-third as long as tlie body, the joints beyond the third just visibly longer than wide, strongly obconical, the third a little longer than the fourth. Prothorax one-half to two-thirds wider than long, llie apex about two-thirds as wide as the base, more or less distinctly arcuate ; base transverse, the sinuations almost obsolete ; basal angles very slightly obtuse, not at all rounded ; sides broadly rounded and convergent anteriorly, almost parallel and more nearly straight toward base; disk excessively finely, densely i^unc- tate and dull. Elytra about three times as long as the prothorax, and, at the middle, qiiite distinctly wider ; humeri not exposed at base ; apex rather acutely ogival ; sides nearly straight in basal two-thirds ; disk excessively densely, finely punctured, with fine, feebly impressed rows of sligbtly larger feeble and scarcely distinguishable punctures. Abdomen polislied, finely, rather sparsely punctured, the metasternum somewhat coarsely and densely so, the prosternum and propleurre extremely densely so and dull. Legs moderate in length, the basal joint of the hind tarsi as long as the remainder. Length 4.5-5.3 mm. ; width l.S-2.2 mm. Arizona. The fourth joint of the maxillary palpi is rather short and robust, the apex intermediate in length between the inner and outer sides. A small species easily known by its excessively dense punctuation and pubescence, the latter being also very short and coarse. 44 H, deplanatlis Champ. — Biol. Cent.-Amer., Coleopt., IV, Pt. i, p. 440. — Oblong, subparallel, rather strongly depressed, feebly shining, pice- ous-brown, the legs and antennae slightly paler ; pubescence coarse, very short, moderately dense. Head small, feebly convex, the punctures distinct, very sparse between the eyes, the latter somewhat large, separated by about two-thirds their width ; antennae stout, rather more than one-third as long as the body, the joints very strongly obconical, the intermediate nearly one-half longer than wide, third distinctly longer than the fourth. Prothm-ax fully one- half wider than long, the apex strongly arcuate and continuous in curvature with the sides, the latter becoming nearly straight and parallel in basal half; basal angles right, not rounded ; base transverse, the sinuations narrow, some- what distinct ; disk rather finely, densely punctate, alutaceous, the punctures Coleopterological Notices, III. 121 not polygonally crowded ; basal foveje almost obsolete. Elytra rather more than three times as long as the prothorax, and, behind the middle, about one- third wider, somewhat abruptly and obtusely rounded behind ; sides just visi- bly arcuate ; disk rather distinctly shining, not very finely, deeply, densely punctate and with distinctly impressed series of slightly coarser, very approxi- mate punctures. Abdomen very minutely, s^jarsely punctate, the prosternum rather densely so but strongly shining. Length 4.8-5.0 mm. ; widtli 1.9 mm. Arizona. Mr. Morrison. Tliis is a small species, somewhat allied to punctatissimus, but easily distinguishable by its sparser punctuation especially of the elytra, and the more distinctly punctate elytral strite, also by its still more depressed form. The two specimens before me appear to be females, as there is no trace of the peculiar sexual modification of the tibiae mentioned by Mr. Champi(tn. 45 H. gemellus n. sp. — Oblong-elongate, somewhat strongly depressed, parallel, dark brownish-piceous, the abdomen blackish, remainder of under surface, legs and antennae paler, rufescent ; integuments somewhat shining, the pubescence short, moderately dense. Head deeply punctured, the punc- tures rather small and well separated between the eyes, finer and denser anteriorly; eyes moderately large, separated by about two-thirds their width ; antennse moderately long and slightly stout, joints strongly obconical, nearly one-half longer than wide, third just visibly longer than the fourtli. Protlm-ax rather more than one-half wider tlian long, the apex broadly, feebly arcuate, three-fourths as wide as the base, not continuous in curvature with the sides, the latter broadly arcuate anteriorly, parallel and nearly straight in basal half, the angles right ; base transverse, the sinuations rather broad and dis- tinct ; disk not impressed, finely, extremely densely punctate throughout, the punctures round, not quite in contact, the very narrow interspaces shining. Elytra quite distinctly more than three times as long as the prothorax and just visibly wider, somewhat abruptly and obtusely ogival at apex, the humeri very narrowly exposed ; sides parallel and nearly straight ; disk somewhat finely and feebly striate, the striae finely but distinctly, closely punctate ; inter- vals finely, confusedly and moderately densely punctate, polished. Abdomen finely, very sparsely punctate. Legs normal, the basal joint of the hind tarsi equal in length to the remainder. Length 6.0-6.3 mm. ; width 2.2-2.3 mm. Arizona. A somewhat inconspicuous species, more or less allied to several others but especially deplanalus. From the latter it is readily separable by its finer and rather sparser elytral punctuation and much larger size. The three specimens before me were formerly a part of the Levettc cabinet. Aksals N. Y. Acad. Sci., VI, Nov. 1891.— 9 122 Coleopter^ological Notices, III. 46 H, uniseriatUH n. sp. — Oblong-oval, rather narrow, convex, highly polished and pale flavo-testaceous throughout ; pubescence somewhat long and semi-erect, coarse, pale and sparse. Head distinctly, evenly convex, coarsely, deeply, rather sparsely punctate ; eyes small, separated by one-half more than their own width ; antennje moderately stout, a little less than one- half as long as the body, the joints rather strongly obconical and scarcely one-half longer than wide, the third scarcely as long as the fourth in the female. Prothorax about one-half wider than long, the apex three-fourths as wide as the base, feebly arcuate ; sides parallel and almost straight in basal two-thirds, the apical angles broadly rounded ; base transverse, the sinua- tions broad and rather distinct ; basal angles right, distinctly, narrowly rounded ; disk broadly, feebly impressed in the middle toward base, coarsely, rather sparsely punctate, the basal foveas small but quite distinct. Elytra nearly four times as long as the prothorax and about one-half wider ; sides parallel, broadly arcuate behind, the apex ogival ; humeri rounded, rather broadly exposed ; disk with series of rather coarse, deep, moderately approxi- mate punctures, the series scarcely at all impressed except very feebly toward the suture ; intervals each with a single even series of very fine punctures. Abdomen finely, sparsely punctate, the prosternum very densely so. Legs moderate, slender; basal joint of the hind tarsi slightly longer than the remainder. Length 5.0 mm. ; width 1.9 mm. California. The unique specimen is a female and it is possible that in the male, the third antennal joint will prove to be quite distinctly shorter than the fourth. This species is decidedly aberrant in the form of the prothorax, which is more subquadrate, in the smaller eyes and especially in the arrangement of the elytral punctures. I am however unable to perceive any structural characters, which would warrant its removal from the present genus. The maxillary palpi are of a common form, the fourth joint being almost evenly recti-triangular, with the oblique apex about equal in length to the outer side. MEIVGECEUS Champ. Assuming M. crassicornis Champ, as the type of this genus, its characters may be briefly stated as follows : — Body oval, rather broad and moderately convex, the sides of the elytra con- tinuous in curvature with those of the prothorax, the basal angles of the latter acute and slightly produced posteriorly. Head small, short, deeply inserted, vertical in repose, the fourth joint of the maxillary palpi very broad, the apex nearly one-half longer than the outer side ; terminal joint of the labial short and robust. Antennae stout, the Intermediate joints dilated in Coleopterological Notices, III. 123 the male. Prosternal process horrizontal, tumid posteriorly, then abruptly vertical and excavated to the level of the prosternal side-pieces. Legs and tarsi throughout as in Hymenorus. The general form of the body approaches some of the species of Cistela or Isomira, but apart from the characters above mentioned the genus is very closely related to Hymenorus. Some of the species of the latter genus such as inquilinus, fusicornis and porosicornis are more or less allied to Menoeceus, but the form is narrower, the prothorax less transverse, and the basal angles not posteriorly produced. This last feature constitutes really the only important difference between Menoeceus and Hymenorus. One species, which however differs from the typical form in having the prosternal process and antennae as in Hymenorus, is described in the Biologia by Mr. Champion from southern Texas; I have seen no representative of it, but the original description is as follows : — m, texailUS. — "Ovate, rather broad, piceous-brown, dull, thickly pubes- cent. Head sparsely and rather coarsely punctured; eyes (%) very large, narrowly separated ; antennae (%) stout, rather short, ferruginous ; prothorax very broad, the disk obsoletely canaliculate behind, the surface closely (but not densely), finely, and shallowly punctured ; elytra finely punctate-striate, the interstices quite flat and finely and rather closely punctured ; legs ferru- ginous ; the lateral lobes of the last ventral segment broad and spoon-shaped and clothed with long hairs at the apex." Length 7j mm. ; width 3i mm. This species is stated to be much broader than M. crassicorms, with the pronotum more finely and sparsely punctured. TELESICJLES Champ. This genus is very closely related to Hymenorus, the characters throughout being similar, with the exception of the form of the prothorax, the apex being transversely truncate and the sides con- vergent toward base and feebly sinuate ; this form is however so radically different from anything known in Hymenorus, as to give quite a distinct and peculiar habitus to the species of Telesicles, and there can be but little doubt that the genus is a really valid one. It is simply a good illustration of the statement made in the introductory remarks to the present family, that generic differences often depend more upon general facies or appearance than upon any decided modification of special organs. J 24 Coleopterological Notices, III. Our single species is as follows: — T. COrdatllS Champ.— Biol. Ceiit.-Araer., Coleopt., IV, Pt. i, No\r. 1888, p. 4.'il. — Oblong, rather depressed, polished and pale ochreous-testaceous tliroughout ; pubescence rather short, semi-erect, coarse and sparse. Head feebly convex, rather strongly, not very densely punctate; eyes small, sepa- rated by nearly one-half more than their own width ; antenna; slender, fili- form, nearly one-half as long as the body, intermediate joints feebly obconical, about twice as long as wide, the third and fourth equal. Prothorax one-half wider than long, the apex transversely truncate, four-fifths as wide as the base, the latter transverse or just visibly, evenly arcuate throughout, the sinuations obsolete ; sides broadly arcuate, convergent in basal third and be- coming strongly sinuate just before the basal angles, the latter right, some- what prominent, not at all blunt ; disk evenly convex, not impressed, rather coarsely and sparsely punctate ; basal fovese broadly impressed and almost obsolete. Elytra about three times as long as the prothorax and one-fourth wider than the disk of the latter, abruptly, acutely ogival at apex ; sides parallel and nearly straight ; humeri narrowly rounded and quite broadly exposed at base ; disk with extremely feebly impressed series of rather coarse deep punctures, which become much less distinct near the apex ; intervals fiat, finely, confusedly and very sparsely punctate. Abdomen finely but dis- tinctly, sparsely punctate. Legs rather short, slender, the basal joint of the hind tarsi nearly as long as the remainder. Length 5.5-5.8 mm.; width 2.0-2.1 mm. Texas (El Paso). Mr. Dunn. There seems to be very little sexual difference, the eyes being- just visibly less distant in the male, and the fifth segment a little more acutely rounded behind in that sex. MYCETOCHARAi Berth. Several attempts have been made to subdivide this genus but all more or less unsuccessfully, for, although easily divisible into groups by certain comparatively constant prosternal characters, it is found that each group contains species which, in general habitus, are strongly suggestive of homologous species in some of the others. 1 The correct designation of this genus is involved in considei-able uncer- tainty, and for this reason I at first determined to make use of the name given in the Munich Catalogue, quite forgetting the familiar fact that Mycetophila had been used by Meigen in 1803 for a genus of Diptera. The word here adopted is that proposed by Seidlitz in the most recent edition of the " Fauna Baltica," and is considered by that author to be two years earlier than Myce- tochares Latr., the former having been printed in 1827, while the latter wa.s not published in a properly latinized form until 1829. Coleopterological Notices, III. 125 In other words each group is so heterogeneous, and the interos- culating lines of affinity between them so numerous, that it seems impossible to consider them as having full generic value. The form and extent of the anterior coxee and of the i)rosternal process which separates them, constitute the best characters for minor subdivisions, for these appear to be the most constant within the limits of the grou])s. The fourth joint of the maxillary palpi is usually in the form of a right-angled triangle, with the right angle at the point of attach- ment, but sometimes the two sides form an angle which is slightly less than right, the apex becoming shorter ; it is generally quite robust, but occasionally becomes decidedly slender. The eyes, tarsi and antennoe vary greatly in size and form in the various species, and appear to be but slightly affected by sex. The sexual differences are stated to be quite pronounced in many of the European species, but in the North American they are cer- tainh^ not remarkably so, and, as there is often much difficulty in determining the sex of individuals, but little attention has been given to this subject in the following descriptions. The punctuation generally varies to a considerable degree, and sometimes appears to be coarse or rather fine in the same individual according to the direction of the reflected light; the elytra often have to be held, therefore, in a very oblique position with reference to the light, in order to see that the impressed lines, which are nearly always distinct, are not accompanied by series of punctures in such species as fraterna and nigerrima. Our species may readily be separated into three groups as follows: Anterioi- coxse rather small, separated by a comparativ^-ly wide prosternal process, the latter longitudinally convex and attaining the level of their apices I Anterior coxse separated by a thin prosternal lamina. The coxae very large, conoidal and prominent, almost contiguous at apex, the prosternal lamina deeply placed between them, and generally more or less horizontal II The coxae rather small, the lamina longitudinally convex and attaining the level of tlieir apices Ill Groups I and II both contain species with and without the red humeral spots, and these groups are peculiar to the eastern parts of the continent. Group III contains no species as far as known with the humeral maculation, and is peculiar to the regions west of the 120 Col copter ological Notices, III. Rocky mountain divide. These p^roups are nearly, but probably not exactly, equivalent to those which have been indicated in the Euro- pean fauna. Gronp I.

This species is one of the smallest of the genus, and may readily be known by its extremely sparse minute punctuation, almost in- visible pubescence and absence of elytral series.

The description refers to the male which appears to be much smaller and more slender than the female. In the latter sex the antennae are relatively shorter and the prothorax is slightly more transverse. Fraterna is more northern in its distribution than haldemani. I think that the unique specimen described by LeConte as lati- collis is simply an extreme form of the female of this species. The punctuation, especially of the head, is very uneven and quite vari- able in fraterna, and there seemingly exists a most perplexing' plasticity in the form of the prothorax in some species — see remarks under tenuis. In fact I have before me a normally punctate speci- men oi fraterna, in which the prothorax is somewhat dilated and rather wider than the elytra, just as in the type of laticollis. Although Melsheimer states that his ruficornis is distinct from fraterna, I am inclined to think that it is nothing more than an Goleopterological Notices, III. 129 immature specimen of this species, or at most a slight variety. According to the description it is "brown, pubescent, densely punc- tulate ; antennae, labrum, palpi and feet testaceous; thorax at base each side of middle with a small and profound impression; dorsal impression obsolete; scutel brown; elytra densely rugulose ; toward the suture with faint traces of the interstices; base broadly and in- determinately testaceous ; beneath pale brown ; femora rather pale testaceous."
