The material now available for systematic work almost invariably proves to be inadequately representative, owing to more or less insufficient collecting. I find, in fact, that in certain genera every lot sent in for identification is made up in considerable proportion of hitherto unknown species or subspecies and, so far as my own systematic efforts are concerned, the present opportunity is there- fore utilized to make known these nondescripts, in order that knowledge of the various groups may be brought nearer to a status approximating completeness. There is scarcely any need of further explanation of an intro- ductory character, other than to state that in certain parts of widely distributed groups a mere description, however carefully drawn up, often fails to afford certainty of identification, it being necessary to make direct comparison with types in order to place the matter beyond doubt. This is to be regretted, but prolonged and involved evolution has brought living forms into a condition of toxonomic complexity which renders such a course necessary, ex- cepting in comparatively few cases. CICINDELID&. Amblycheila Say The deep black subalutaceous species of this genus form a rather natural group, probably having a subgeneric status. To the three species already described, a fourth must now be added as follows: Amblycheila ventricosa n. sp.—Body much more ventricose than in any other species, similar in the deep black color and subalutaceous lustre; head similar, but with the middle of the labrum even more prominently though similarly approximately bilobed; antennz as in enodis, shorter than in longipes; prothorax as in the former, the sides less oblique and more rounded than in longipes; elytra differing very much, short, barely more than one-half longer than wide, widest at about basal third, the humeri broadly rounded; punctures small and sparse, the surface without trace of subcariniform lines; legs and tarsi somewhat as in enodis, shorter than in longipes. Length (2) 20.5 mm.; width 7.6 mm. A single female from the Huachuca Mts., Arizona. The four species of this subdivision of Amblycheila may be distinguished readily among themselves as follows: 2 MEMOIRS ON THE COLEOPTERA Elytra with moderately coarse impressed punctures, sparse as in the other species, more conspicuous laterally, where there are feeble traces of comminuted raised threads at base [Rivers]. Prothorax scarcely an eighth wider than long, with strongly, subevenly arcuate apex and very moderately oblique, broadly arcuate sides; elytra only three-fifths longer than wide, widest rather before the middle, with rapidly but obtusely rounded humeri, a little more than a third wider than the prothorax and two and a fourth times as long; legs slender, defective in the type. Length (c") 22 mm. Arizona. baroni Rivers Elytra with small, inconspicuous and very sparse punctures, each bearing a minute anteror aSpenity—. - 2. < oe cio eine eves a teks sale eeoteh spk 2 2—Elytra with two fine cariniform discal lines at each side; oblique sides of the prothorax feebly arcuate in both sexes. Body notably elongate, the antennee (@) fully two-thirds as long as the body; prothorax about a fifth wider than long, broadly, subevenly arcuate at apex; elytra more than three-fourths longer than wide, between a fourth and third wider than the prothorax and nearly two and one-half times as long, widest at the middle; ground sculpture consisting of small shallow and indefinite indentations. Length (co?) 21.7-23.0 mm.; width 7.0-7.6 mm. Arizona (Baboquivari Mts.) f ; longipes Csy. Elytra with a single very fine cariniform sublatera! line in about basal half; anterior margin of the prothorax feebly, subangularly prominent at the middle, the oblique sides of the latter evenly but much more strongly arcuate than in Jongipes; antenne and legs not so long as in the latter species... ..3 3—Body notably narrow and elongate, though feebly ventricose; elytra fully three-fourths longer than wide, widest at the middle, two-fifths wider than the prothorax and two and one-half times as long; alutaceous ground smooth, not at all punctulate.

Body relatively shorter and much more strongly ventricose; elytra about one- half longer than wide, widest well before the middle, relatively much more acuminate behind than in enodis, about one-half wider than the prothorax and two and one-half times as long, the alutaceous ground with minute but distinct punctures, which are linearly arranged. Length (9) 20.5 mm.; width 7.6 mm. Arizona (Huachuca Mts.)...............- ventricosa Csy. These descriptions are all drawn from the original types, that of baroni being in the form of a greatly enlarged photograph published in Zoe (IV, plate XXIX, 1893). They all represent distinct species and should not be considered varietal forms. The type of baroni is said to have been taken near the Gila River, in Southern Arizona, so that the type localities, as may be noted, are all rather widely separated, with the attending environmental conditions quite different. The disjointed raised threads at the sides of the elytral base are not indicated in the photograph of baront. Omus Esch. This genus is comparatively recent geologically and, in conformity with the general rule in such cases, exhibits very marked plasticity, so that nearly every mountain valley of the Pacific coastal regions AppiITIons TO NORTH AMERICAN COLEOPTERA 3 has one or more peculiar type-forms or formas, as termed by Dr. Blaisdell in treating the genus Eleodes, which has very similar peculiarities in these respects. In the case of Omus—very abundant in California and de- creasingly so northward to Puget Sound—there are probably over 200 of these derivative forms, the exact interrelationships of which, in the customary nomenclatorial terminology, it is quite impossible to determine definitely at present. So I have merely assigned names to the recently discovered forms, without attempting to fix their exact taxonomic status. It can only be said that when these forms are placed in juxtaposition, nearly all could see that there is a very appreciable difference, always in several respects, although it is well-nigh impracticable to so describe them in words as to render them unmistakably identifiable—that is,in most cases. The only way that this can be done satisfactorily is to give carefut outline descriptions and measurements, especially indicating the exact geographic localities; this last being one of the most important of the descriptive elements in the fuller revisions to be given in future years, but unfortunately not always definitely known at present. It is a good deal as in identifying fossil mollusks, for where the exact horizon is given it is generally possible to identify the species, but if the horizon be unknown this would be almost im- possible, except in the case of strikingly distinct species. The following forms, which are very often truly specific in value, are simply compared with those already published, among the latter of which I am unable to discover any actual synonyms, even lucidicollis, which I reduced to synonymy in my last work on the genus, proving to be distinct and of a varietal nature, as shown by the male and female at hand, and not by any means a.true synonym. The habit of inscribing all subordinate names as un- differentiated synonyms—the method adopted in several modern catalogues—is untruthful and misleading and therefore not con- ducive to scientific progress. The two following belong to the audouini group of the genus: Omus audens nov.— Moderately stout and convex, deep black and of moderate lustre; head well developed, with notably convex eyes, the front with shallow sparse rugula and deep oblique impressions, between which the punctures are deep, isolated and conspicuous, the epistoma smooth, with two large punctures toward each side; labrum with a prominent, medially truncate lobe; antenne very moderate and filiform; prothorax but little wider than long, the feebly arcuate sides moderately oblique from apex to base, the side margins not attaining the base; surface smooth, with very feeble ruguliform lines; anterior transverse impression shallow, the surface thence to apex with more distinct transverse 4 MEMOIRS ON THE COLEOPTERA rugulosity; elytra very evenly oval, nearly two-fifths wider than the prothorax, with somewhat coarse separated punctures, the fovee rather small, not conspic- uous; legs slender, moderate. Length (2) 17.5 mm.; width6.2mm. Washing- ton State (Seattle). Allied to cephalicus, but with narrower and less transverse prothorax, more distinct isolated medio-frontal punctures, rather less coarse elytral punctures and more convex eyes, when compared with the female of the latter. From ambiguus and soctus it differs very much in the shorter and more filiform antenne. Cephalicus should be regarded as a species, with rugipennis, tacome and audens as subspecies; the last is from a more northern locality than any other known to me, excepting facome and distans, the former being much the smallest of the four. Omus socius nov.—Form rather short and stout for this section, deep black, with moderate lustre, the anterior parts alutaceous as in ambiguus; head slightly narrower than the prothorax, with sparse feeble rugulosity, scarcely becoming punctiform between the deep oblique impressions, the epistoma smooth, rugulose along its base, having a single puncture at each side, the labrum unevenly, prominently lobed in the middle; eyes moderate but unusually convex; antennz long, notably thick, distally attenuate; prothorax slightly transverse, the oblique sides moderately arcuate, the margin not quite attaining the base; surface smooth, the lines very feeble, the anterior impression rather sharp and deep; elytra evenly oval, a third wider than the prothorax; punctures coarsely impressed, separated moderately, the fovez inconspicuous; anterior male tarsi with joints one and three but little narrower than the second; hind tarsi much longer than the tibiae. Length () 16.3 mm.; width 6.0 mm. California (Shasta Co.). One specimen. This form is the only one closely associable with ambiguus, but it is evidently shorter and relatively broader, with much more convex eyes, coarser elytral punctures and less evenly medio- truncate lobe of the labrum. It is the form which I originally identified as ambiguus, because of the very thick, distally attenuate antenne, but closer observation shows that it differs in its broader and more abbreviated outline, much more convex eyes, stronger elytral punctuation and some other characters. It may be regarded as a subspecies of ambiguus. The species described by Blaisdell and Reynolds under the name cupreonitens seems to come in certain features between the audouini and californicus groups of the genus. The antenne are rather short—a frequent character.in the former group—and the pronotal ruge are shallow and widely separated. The small and notably sparse elytral punctures, with deep conspicuous scattered foveze, constitute a prominent feature and, although the lustre of the body is very shining throughout and not quite deep black, it scarcely AppITIONS TO NoRTH AMERICAN COLEOPTERA 5 merits its name, as the lustre is never decidedly cupreous. The following may be regarded as a subspecies: Omus reynoldsi nov.—Notably slender, black, very shining, the elytra not metallic; head rather long, barely narrower than the prothorax and with sparse and feeble rugulosity, the frontal impressions deep, oblique; labrum virtually transverse at apex; antenne rather long, notably slender; prothorax about as long as wide, the sides broadly arcuate, straighter and more oblique posteriad, becoming almost parallel anteriad; base transverse, barely visibly bisinuate; surface with large but feeble rugulosity, the anterior transverse sulcus very deep throughout; elytra narrow, nearly twice as long as wide, the sides gradually converging and in part almost straight from near the middle to the very narrowly rounded humeri; punctures coarse and deep, separated by between once and twice their diameters, the sparse fovee very large and conspicuous. Length (<7) 12.0 mm.; width 4.4 mm. California (Humboldt Co., Arcata—beach). One specimen. The single type at hand was included in a large series of cupreo- nitens sent to me by Mr. Reynolds; it stands apart quite distinctly by its narrow form and basally subcuneate elytra. The elytra in the male of cupreonitens are evenly oblong-oval, with broadly and gradually rounded humeri. Besides calzfornicus, latipennis, opacipennis, vermiculatus, sculptilis, mimus, oregonensis, semilucens and diminuens, constituting the californicus group, I have now to add the following sixteen forms, all similarly from the coast mountains, this region having been lately much more thoroughly explored than formerly. MJimus is still represented by two very slender male specimens from San Francisco, and sculptilis by a single male, having very peculiar fine deep and dense pronotal rugulosity. The two following forms are allied to sculptilis: Omus densicollis nov.—Moderately narrow, deep black, with dullish lustre on the elytra, moderately ventricose; head well developed, densely and strongly vermiculate, the ruge longitudinal between the moderate anterior impressions and along the base of the epistoma; labrum broadly, circularly lobed; eyes moderately convex, the antenne scarcely half as long as the body; prothorax nearly a fifth wider than long, the sides arcuate, gradually more oblique posteriad, the base nearly truncate; surface with fine, dense and deep vermiculate ruge, the anterior impression feeble, the ruge sparser and more longitudinal thence to the apex; elytra oblong-oval, more attenuate posteriad, subtruncate, with evident humeri at base, loosely and not coarsely punctate, with the fovee in- distinct, two-fifths wider than the prothorax and not quite three times as long; legs rather short. Length (9) 15.0 mm.; width 5.7 mm. California (Men- docino Co.) ,—Leach. Differs from sculptilis (@) in the more prominent arcuation of the labrum, partially rugose and not wholly smooth median parts of the epistoma, slightly thicker antenna, sparser anterior ruge of the prothorax and smaller and much sparser elytral punctures. 6 MEMOIRS ON THE COLEOPTERA The sides of the prothorax become oblique only nearer the base in sculptilis. Omus argutus nov.—Larger than densicollis and less ventricose, with much broader prothorax, deep black, rather dullish in lustre; head more distinctly narrower than the prothorax, but otherwise nearly similar throughout; antenne thicker than in sculptilis, much less than half as long as the body, the fifth joint two and one-half times as long as wide; prothorax nearly a fourth wider than long, widest near anterior third, the sides arcuate, gradually oblique behind the widest section; sculpture vermiculate and dense but much more superficial than in densicollis or sculptilis; anterior impressed line feeble; median line somewhat as in the latter, much finer and shallower than in denstcollis; elytra formed nearly as in densicollis, scarcely a third wider than the prothorax and nearly three times as long; punctures rather coarse and well separated, with very inconspicuous fovee; legs longer than in sculptilis or densicollis. Length (9) 17.0mm.; width 6.2mm. California (Alameda Co.),—Leach. It is quite evident that scu/ptilis should be regarded as a species, with the two above described attached as subspecies. The following is a subspecies of mimus; the latter should be accorded specific rank: Omus debiliceps nov.—Notably small in size and very slender, shining, not metallic, the elytra alutaceous; head unusually small, narrower than the pro- thorax, with eyes rather small, strongly rugulose, the medio-frontal area between the large impressions nearly smooth; labrum almost transversely truncate, the lateral sinuses small and feeble; antennz slender and filiform, not quite half as long as the body; prothorax not much though sensibly wider than long, the sides parallel and rounded, becoming oblique and nearly straight in about basal half; surface with the deep vermiculate rugulosity rather fine and dense; anterior impression deep; elytra nearly twice as long as wide, scarcely a third wider than the prothorax, oblong-oval, the punctures rather small, notably sparse, well separated even at the sides; anterior male tarsi not very widely dilated. Length (@) 13.5 mm.; width 4.7 mm. California (San Francisco). Differs from mimus in its still smaller size and narrower outline, decidedly smaller head, smaller eyes and sparser elytral punctures, with similar feebly marked fovee. The following four forms may also be regarded as subspecies of mimus: Omus insulsus nov.—Narrow, only moderately convex, shining, deeply and vermiculately sculptured anteriorly, the elytra opaculate, with small, rather sparse punctures and very moderately developed foveee; head very nearly as wide as the prothorax, with well-developed and very convex eyes, the epistoma sparsely rugose throughout, the labral lobe broadly rounded and distinctly prominent; antenne slender and filiform, the fifth joint almost three times as long as wide; prothorax but little wider than long, the broadly, evenly rounded sides gradually converging to a broad sinus toward base, the edges fine and attaining the base, which is transversely truncate; anterior line fine, almost obliterated medially; elytra evenly elongate-oval, about two-fifths wider than the prothorax, scarcely two and one-half times as long; legs moderate; anterior male tarsi somewhat strongly dilated. Length (co 2) 13.0-16.0 mm.; width 4.7-5.3 mm. California (Sta Cruz Co.),—Leach. AppITIONs TO NORTH AMERICAN COLEOPTERA 7 Recognizable by the deep ruge covering the entire head, the prominent eyes and other characters, especially the broadly sinuate sides of the prothorax toward base. Omus modicus nov.—Rather more elongate, similarly deep black, the anterior parts nearly similar in sculpture, which is deeply vermiculate, with the dullish elytra very moderately but rather less loosely punctate; head and labrum nearly similar but smaller, the eyes not quite so prominent; antenne almost, similar; prothorax virtually similar in size but quite different in outline, being strongly rounded at the sides more apically, the sides thence oblique and straight to the base, without trace of sinuation viewed vertically; the strong vermiculation similar, the anterior line fine but rather deeper; elytra almost similar though slightly more elongate; anterior male tarsi moderately dilated. Length (<) 14.0-14.5 mm.; width 5.0-5.1 mm. California (Mendocino Co.),—Leach. Two male specimens. Differs much from insulsus in having the sides of the prothorax oblique and straight posteriorly, without the sinuation of the preceding form, although this sinus is usually evident from an oblique lateral viewpoint. Omus stolidus nov.—Shining, black, the elytra a little less shining; outline ' broader than in either of the preceding; anterior parts deeply and coarsely, but not very densely vermiculate; oblique frontal impressions distinct and nearly similar, the eyes similar; antenne longer, filiform, the fifth joint three times as long as wide; prothorax slightly wider than the head, the sides arcuate, gradually oblique and straight posteriad; side margins not attaining the base; anterior transverse line deep and acute throughout, the surface thence to the apex with very coarse, well-separated longitudinal rug; elytra very evenly oval, broader than in modicus, fully two-fifths wider than the prothorax, the punctures rather stronger but not closer, the fovee more evident; anterior male tarsi with the second joint much wider than the first or third. Female larger and broader than the male, the anterior rugulosity rather denser and less coarse, the prothorax slightly more transverse; elytra more rugosely punctate. Length (@ 2) 14.5- 16.0 mm.; width 5.6-6.2 mm. California (Mendocino Co.),—Leach. Easily distinguishable from modicus by its broader outline, larger size and rather more elongate antenna, as well as several other minor characters, such as the deeper anterior thoracic line and more evident elytral fovee. Omus subparallelus nov.—More parallel than any of the preceding three or mimus, and with relatively much more developed and broader prothorax, as well as more remote elytral punctures; anterior parts closely and deeply vermiculate; head with moderate convex eyes and rather deep anterior oblique frontal im- pressions; labral lobe moderately prominent, with its apex narrowly truncate; antenne slender and filiform, the fifth joint two and one-half times as long as wide; prothorax large, slightly though distinctly wider than long, the sides evenly and distinctly arcuate, moderately converging posteriad, the fine side margins attaining the base; anterior incised line deep, but obsolescent medially; elytra narrow, twice as long as wide, oblong-oval, only a fourth or fifth wider than the prothorax, two and one-half times as long; punctures fine and very 8 MEMOIRS ON THE COLEOPTERA sparse, the fovee moderately distinct; anterior male tarsi well dilated. Length (%) 14.3 mm.; width 5.1 mm. California (Sta. Cruz Co.),—Leach. One specimen. This form is almost undoubtedly of specific value; it is very distinct in appearance from the preceding three and others of the mimus group. The-following may be placed near the preceding mimus group, but has the fine dense pronotal sculpture somewhat as in the sculptilis group: Omus ventricosus nov.—Anterior parts unusually narrow when compared with the hind body, deep dullish black throughout; pronotum rather finely, closely vermiculate, becoming almost smooth along the fine median line; head a little more coarsely rugose, more finely antero-medially, the oblique impressions deep; epistoma in great part smooth, the labral lobe broadly, evenly arcuate and but slightly prominent; eyes moderate but very convex; antennz unusually long, more than half as long as the body, the medial joints three times as long as wide; prothorax distinctly wider than the head, almost as long as wide, the sides moderately arcuate, a little less so and converging behind the middle; side margins attaining the truncate base, the anterior line feeble; elytra three-sevenths wider than the prothorax, two and one-half times as long, evenly oblong-oval; punctures coarse, slightly separated, the surface somewhat rugulose, the fovee well developed though not conspicuous; anterior male tarsi well dilated. Length (@) 14.0 mm.; width 5.4 mm. California (Mendocino Co.),—Leach. This seems to be a true species; it is of rather small size and peculiar sculpture, long antenne, ventricose outline and rather dull surface lustre. The following may stand near ventricosus, presumably as a subspecies, but it differs strikingly in the very much coarser and stronger ruge and the relatively broader anterior parts: Omus leachi nov.—More shining throughout and broader, the ruge of the anterior parts coarse, deep and conspicuous throughout, becoming obsolete and finely, sparsely punctulate between the very shallow short frontal impressions; head but slightly narrower than the prothorax, with moderate though very convex eyes, the labral lobe very short, broadly arcuate, separated from the equally prominent sides by feeble sinuses; antennz not quite half as long as the body, the medial joints about three times as long as wide; prothorax fully a fifth wider than long, the sides very moderately arcuate, slightly more converging in basal half; anterior incised line fine and moderate; elytra oblong-oval, about a third wider than the prothorax, the surface somewhat rugose; punctures coarse and rather close, the fovee deep but somewhat indistinct; anterior male tarsi dilated as usual. Length (@ 2) 13.5-16.7 mm.; width 5.1-6.2 mm. California (Trinity Co.),—E. R. Leach. Four specimens. There is a good deal of variation in size in this form, the type being much larger and definitely more slender, but in general characters and sculpture they are practically similar throughout. ADDITIONS TO NORTH AMERICAN COLEOPTERA 9 The following seems to be specifically distinct, having no near analogues to my knowledge: Omus pullatus nov.—Only feebly ventricose, deep black and moderately shining, the anterior parts rather strongly but not very densely vermiculate throughout; head distinctly narrower than the prothorax, with rather large, strongly convex eyes, the oblique impressions very shallow; labral lobe moderate, medially truncate; antenne barely half as long as the body, rather thicker than usual, the medial joints slightly less than three times as long as wide; prothorax peculiar, rather large, unusually convex and with the sides evenly and strongly arcuate throughout, more converging basally, the edges attaining the truncate base; median line fine, the anterior incised line distinct; elytra very evenly oblong-oval, rather obtusely angulate at apex, a third wider than the prothorax, the punctures strong but loose, separated by fully twice their diameters discally; anterior male tarsi more broadly dilated than usual. Length (o) 15.5 mm.; width 5.6mm. California (Sonoma Co.). This form stands apart and by itself, so that it cannot be assigned very satisfactorily, but it may be placed with opacipennis. The forms named vermiculatus and latipennis, which constitute a species under the first name, are distinguished by the sides of the prothorax being oblique from apex to base and very feebly arcuate to nearly straight, giving a peculiar appearance, somewhat as in edwardsi. The following is another subspecies of this species: Omus pollens nov.—Body much larger than in vermiculatus and latipennis, rather dullish in lustre and deep black as usual, very moderately ventricose, the anterior parts somewhat loosely vermiculato-rugose, the head more strongly than the prothorax; head well developed, slightly narrower than the prothorax, with rather large and prominent eyes, the impressions short and moderate; epistoma obliquely impressed laterally; labral lobe moderate in prominence, very obtusely rounded; antenne less than half as long as the body, rather thick but with the medial joints about three times as long as wide; prothorax large, a fourth wider than long, the sides evenly, moderately rounded and equally convergent from apex to base, the latter broadly bisinuate, attained by the side margins; median line fine, the anterior incised line fine and feeble, the surface thence to apex with longitudinal ruge—very fine apically, coarser basally; elytra oblong-oval, more attenuate behind the middle, a third wider than the prothorax, the punctures strong, separated by about twice their diameters discally. Length (2) 20.0 mm.; width 6.6mm. California (Marin Co.). This subspecies is much larger than the two above mentioned, the elytra somewhat similar in shape to those of vermiculatus, but much longer and less truncate at base than in latipennis. In the type the suture is dehiscent in apical fourth, but this is probably acci- dental. Finally the three following forms should be compared with the smaller and more slender semtlucens, all having the elytral punctures remarkably sparse; they may be placed as subspecies of the true californicus: 10 MEMOIRS ON THE COLEOPTERA Omus turbulentus nov.—Rather stout, polished throughout but not metallic, the vermiculate ruge of the anterior parts coarse, deep and very conspicuous, irregular; head slightly narrower than the prothorax, with somewhat small but convex eyes; anterior impressions moderate but oblique, separated by a strongly rugose surface; epistoma smooth except at base, the labral lobe broad, very slightly prominent medially; antenne slender but shorter than usual, the medial joints barely two and one-half times longer than wide; prothorax large but abbreviated, nearly a third wider than long, widest near apical third, the sides thence oblique and very feebly arcuate to the base, which is subrectilinear; ruge transverse along the fine median line, densely confused between the fine feeble anterior line and the apex; elytra oval, ogivally attenuate behind the middle, two-fifths wider than the prothorax and about three times as long; punctures not very coarse but deep, separated by from two to three times their diameters on the disk, the fovew rather small but distinct. Length (2) 17.0 mm.; width 6.6 mm. California (Sonoma Co.). Readily recognizable by the short and very strongly, loosely vermiculate prothorax, shining, oval, posteriorly attenuate and sparsely punctured elytra and rather short antenne. Omus ethiops nov.—Form, shining lustre and sculpture almost as in the preceding, but with the elytral punctures not quite so large; head coarsely, deeply rugose throughout, the impressions small and shallow; epistoma broadly, angularly sinuate, the labral lobe very broad, feebly arcuate; eyes very moderate in size and convexity; antenne rather slender, about as long as the head and prothorax, the fifth joint three times as long as wide, longer than the fourth or sixth; prothorax in outline nearly as in the preceding but still more coarsely and deeply rugose, differing completely, however, in the surface between the less apical and somewhat deeper anterior line and the apex, which is here loosely covered with very deeply incised and longitudinal ruge; elytra more elongate, less rapidly attenuate behind the middle, similarly evenly oval basally, a third wider than the prothorax and rather more than three times as long, the punctures not quite so coarse and less sparse, the fovee similar. Length (2) 16.5 mm.; width 6.3 mm. California (Shasta Co.). Another very distinct shining species, with loose deep elytral punctures, resembling turbulentus, but easily distinguishable by the longer antennal joints and very different sculpture of the apical part of the pronotum; the prothorax is relatively larger. Omus sparsus nov.—Anterior parts relatively narrower than in the two preceding, more ventricose, shining but with the elytra less so; vermiculate rugz throughout the head and prothorax uniform and strong but less coarse than in @thiops; head narrower than the prothorax, with rather small but strongly convex eyes, the impressions short, feeble and oblique, separated by a closely rugose surface; labral lobe broadly, evenly arcuate and somewhat prominent; antennz slender, less than half as long as the body, the medial joints not quite three times as long as wide; prothorax a fifth wider than long, with arcuate posteriorly more converging sides, the fine reflexed margin becoming sinuate near the base; anterior incised line distinct laterally but obsolete at the middle; base very feebly bisinuate; elytra oblong-oval and with more distinct humeri than in the two preceding, only three-sevenths wider than the prothorax, convex; punctures small, separated by about three times their diameters on the disk, ADDITIONS TO NORTH AMERICAN COLEOPTERA II still finer and remotely separated at the sides and apex; fovee small but deep and distinct. Length (9) 16.5 mm.; width 6.2 mm. California (Sta. Cruz),— E. R. Leach. Very readily separable from the two preceding by the narrower anterior parts and relatively more inflated and finely, sparsely punctate elytra, also by antennal structure and peculiarities of sculpture. In regard to blaisdelli and cribripennis—among the largest of the genus in size—the antero-median surface of the front, between the shallow impressions, is finely and closely rugose, without trace of a puncture in any of my specimens, and the elytra are evenly oval and widest at the middle. In intermedius Leng, the median part of the front between the impressions ‘“‘is smooth and sparsely punctate”’ and the elytra are described as widest in front of the middle. So intermedius is evidently not the same species as blaisdelli or the others of this Sierran group. There are two sections of the group, represented by blazsdelli, with notably prominent and strongly rounded labral lobe, and cribripennis, which has the lobe very broad and feebly rounded, scarcely at all prominent; they may be regarded therefore as specifically different; the following are two subspecies: Omus torvus nov.—Elongate, very moderately ventricose, dullish in lustre throughout; head distinctly narrower than the prothorax, rugose throughout, as coarsely and deeply between the impressions as elsewhere; labral lobe rather narrow, rounded and very prominent; antenne rather thick, as in Ddlaisdelli, but somewhat less elongate; prothorax as in that species but shorter, fully a fourth wider than long, strongly narrowed basally; surface rather deeply rugose longitudinally between the feeble anterior line and the apex; elytra three-sevenths wider than the prothorax, evenly oval, with moderate and somewhat sparse punctures, the fovee rather indistinct. Length (9) 20.0 mm.; width 6.8 mm. California (Lampson’s Flat—1800 feet),—Blaisdell—Letcher. Closely allied to dlaisdelli but stouter and with shorter prothorax; the antenne are also thicker. Ome maurus nov.—Somewhat as in cribripennis but smaller and notably more slender, the head almost similar, the medio-frontal surface finely, closely and unevenly rugose; labrum similarly almost truncate, the lobe very short and broad; antenne notably long, not very slender; prothorax narrower in both sexes, only a fifth or sixth wider than long, finely but rather strongly rugulose, the ruge denser and more confused than in cribripennis, where they are more subtransverse; anterior part similarly finely, longitudinally rugulose, the incised line subobsolete except at the sides; elytra evenly oval, nearly twice as long as wide, two-fifths wider than the prothorax, widest exactly at the middle; punctures strong and close-set but less coarse than in cribripennis. Length (@@) 17.0- 18.5 mm.; width 6.0-6.4 mm. California (El Dorado Co.). Three specimens. 12 MEMOIRS ON THE COLEOPTERA Much smaller and especially narrower than cribripennis, the strong elytral punctures not so coarse. The sides of the elytra become more rapidly rounded at base in that species, but here are very gradually rounded basally. Cribripennis is from Placerville, but the locality of maurus is not given, except as stated. Inter- medius Leng is from Coulterville, Mariposa Co. The following is one of the numerous subspecies of horni, over- looked till now: Omus callosus nov.—Short and rather broad, moderately shining, the anterior parts opaculate; head narrower than the prothorax, with well-separated but rather deep ruge, extending over the entire front, the impressions very shallow; labral lobe somewhat prominent and narrowly rounded; antenne thick, the joints rapidly narrowed at base, the fifth distinctly less than three times as long as wide; prothorax almost a third wider than long, the sides rather strongly, evenly arcuate from apex to base, which is feebly bisinuate; lateral margins not quite attaining the base; surface with fine but deep ruge, becoming virtually smooth except toward the sides, apex and base, the anterior line obsolete, feeble at the sides, the median line very fine; elytra short, evenly oval, scarcely over a fourth wider than the prothorax, coarsely and deeply punctate and subrugulose, the punctures separated by their own widths; anterior male tarsi well dilated. Length (o) 13.8 mm.; width 6.1mm. California (Tuolumne Co.). This form may be said to be closest to hornt and farctus, but it is much smaller in size. Cicindela Linn. A number of interesting additions have come to light in recent years, mostly varietal as judged by the prevailing concepts, but in most cases not positively determinable as to taxonomic status; all that can be said is that they possess very definite and consistent differences. Those which it seems desirable to characterize at the present time are as follows: Cicindela montana ssp. uteana nov.—Obscure subcupreous-brown, only slightly shining, the sculpture as in montana, the coloration not black, as in that species, and the lustre rather duller, the sculpture similar; median pronotal line more deeply impressed; antenne more metallic. Length (o@) 12.5 mm.; width 5.3 mm. Utah (Provo). Mr. Tom Spalding. One specimen. The outline is shorter and broader than in montana, the elytra barely more than one-half longer than wide, with merely a very fine remnant of the oblique median band. The abdomen is not very feebly metallic as in montana but bright blue-green. Cicindela oslari ssp. densissima nov.—Narrower than oslari and more convex, subopaque, obscure rufous in color; under surface polished, more or less green; head as in longilabris; prothorax obtrapezoidal, nearly one-half wider than long; elytra almost twice as long as wide, with a small humeral and larger post-humeral white spot, the usual well-developed elbowed median band and a posterior mar- AppITIONS TO NORTH AMERICAN COLEOPTERA 13 ginal spot, which is prolonged posteriorly along the edge for a short distance; punctures throughout very dense and subconfluent; line of fovee very feebly developed, almost obsolete. Length (2) 14.0 mm.; width 5.4 mm. Locality unrecorded—probably Colorado. Differs from oslari in its very much denser elytral punctures, narrower outline and more convex surface. Cicindela oslari ssp. estesiana nov.—Shorter and broader than the preceding, convex, more shining, obscure bronzed in color, dark green beneath, the abdomen black posteriad; head as in all the Jongilabris group; prothorax one-half wider than long, nearly as in the preceding, but with more rounded sides; elytra (9 ) scarcely two-thirds longer than wide, narrower (<), with a fully developed humeral lunule, sometimes resolved into two spots, a well-developed elbowed middle band and a fully developed apical lunule, all white, the apical lunule frequently wanting, except its dilated anterior end; punctures less asperate than in the preceding and well separated—usually by their own diameters; the fovee of the entire discal line are deep and conspicuous. Length (7) 13.5, (2) 14.0 mm.; width (7) 4.9, (2) 5.5 mm. Colorado. Three specimens. Smaller than os/ar1, not at all cupreous but obscure bronze and with much more developed elytral maculation. Cicindela oslari ssp. terracensis nov.—Much narrower and more elongate than oslari, rather convex, subopaque and deep black in color; polished under surface blackish, the first two ventrals dark green; head as usual, finely strigilate, the large labrum white, with its median tooth sinuato-truncate; prothorax obtrapezoidal, about one-half wider than long, finely, extremely densely sculptured and opaculate; elytra twice as long as wide (o), with a large white humeral spot, a small post-humeral spot, a well-defined elbowed median band, somewhat smaller than in the two preceding and os/ari, and a posterior spot distant from the margin; punctures deep, asperulate and densely crowded or coalescent. Length (co) 14.0 mm.; width 5.25 mm. British Columbia (Terrace),—Mrs. W. W. Hippisley. It is highly probable that this should be considered as a distinct species of the longilabris group; laurenti Schpp. and ostenta are also distinct species, so far as I can determine. Cicindela ostenta ssp. columbiana nov.—Form, coloration and coarse sculpture as in ostenta, bright green, the outline slightly narrower; head and prothorax nearly similar; elytra with similar markings, except that the middle band is not strongly oblique, its general course being transverse, very feebly oblique internally. Length (@) 13.0 mm.; width 4.7 mm. British Columbia. One specimen. The third anterior male tarsal joint is parallel, not obconic as it is in ostenta, and the slender hind tarsi are notably more elongate. The forms ostenta and columbiana are not to be confounded in any way with the purely Sierran perviridis Schpp., as the much coarser sculpture and more shining surface give them a very different appearance. Placerensis Csy. seems to be merely a variety of perviridis, with shorter prothorax. T. L. Casey, Mem. Col. XI, Mar. 1924.—2 14 MEMOIRS ON THE COLEOPTERA Cicindela scutellaris ssp. billingsi nov.—Form, coloration and sculpture nearly as in scutellaris, but narrower and with longer prothorax; labrum shorter, the three very acute teeth nearly similar but larger, the front edge laterally virtually transverse and not oblique; front even more coarsely strigose but having only few sparse short hairs in the male; antenne with the fourth joint shorter. Length (@) 11.0 mm.; width 4.5 mm. Montana (Billings). One example. To be distinguished readily from scutellaris by the nearly bald head in the male and the shorter labrum, with more transverse anterior margin. The antenne are wholly glabrous in the type, but probably in large part due to accidental causes, as the type has evidently been subjected to rough treatment. Cicindela shantzi n. sp.—Body nearly as in scutellaris, but with the elytra more abbreviated, of a duller coppery hue, similarly alutaceous, feebly punctate and with a rounded white spot near the middle between outer third and fourth, also each with a white apical lunule, which is gradually attenuated externally; labrum with the three teeth smaller and more approximate, together occupying scarcely more than a fourth of the width; strigose front in the male with only very few short hairs, the antenne nearly glabrous; prothorax with the sides much more nearly parallel from apex to base. Length (o) 11.7 mm.; width 4.8 mm. Colorado. One specimen. I do not think that this form can justly be considered otherwise than as a true species of the scutellaris series. The true species in this section are represented first by wnicolor, carolina and nigrior, second by scutellaris and billingsi, third by shantzi, fourth by mod- esta, rugifrons and lecontei and fifth by criddlet. Cicindela spaldingi n. sp.—Rather narrow, moderately convex, bright green above and beneath, with many long white hairs beneath and also at the sides of the prothorax, moderately shining; head finely and closely strigilate, bald in the male; labrum white, short and transverse, with a broad truncate median lobe; antenne rather long, the first joint with a few long white hairs; prothorax a third wider than long, narrowed but little at base; surface deeply impressed, finely and closely sculptured medially, less finely toward the sides; elytra three- fourths longer than wide, the entire sides and apex broadly white, with two small subequal sinuses toward base, broadly dilated at the middle, the dilated part with a short posterior internal lobe, which is very narrowly separated from the broad white margin; punctures strong and close; anterior male tarsi extremely narrowly dilated, narrowly and briefly, very closely clothed beneath. Length (@) 12.0 mm.; width 4.7mm. Utah (Callao),—Mr. Tom Spalding. Allied somewhat to willistont, but with much broader and entire white elytral margins, coarser elytral punctures and apparently very different male sexual characters at the abdominal apex, the sixth segment not being very deeply, angularly incised, as it is in willistoni, but convex and with a very minute apical emargination. Cicindela parowana ssp. remittens nov.—Larger than parowana, rather less shining and differing in coloration; head green, the entire vertex cupreous; ADDITIONS TO NORTH AMERICAN COLEOPTERA I un labrum white, strongly, arcuately lobed, the median tooth narrow, long and aciculate; front closely covered with long whitish hairs, except near the sides; prothorax wholly cupreous, the deep impressions blue, obtrapezoidal, with arcuate sides, two-fifths wider than long; surface closely, subtransversely rugulose, rather shining; elytra parallel, two-thirds longer than wide, the maculation almost exactly as in parowana, the punctures not quite so small, sparse, the fovee of the line subsimilar; posterior tarsi but little longer than the tibiz. Length (2) 12.5 mm.; width 4.75 mm.. Utah (Callao),—Spalding. Evidently closely allied to parowana, but larger and with cupreous anterior parts and longer, more aciculate median labral tooth. I have only a single specimen, compared with three of parowana, where the upper surface throughout is bright shining bluish-green, excepting the maculation. Cicindela kirbyi ssp. uintana nov.—Stouter than kirbyi and more blackish, similar in sculpture, blackish throughout above, entirely green to blue-green beneath; labrum and anterior frontal cluster of sete as in kirbyi; prothorax subsimilar, but blackish and more opaque; elytra three-fifths longer than wide, the white markings as in kirbyi but very much broader and more conspicuous. Length (2) 14.0 mm.; width 5.8mm. Utah (Zion Cafion). One specimen. Easily separable from kirbyi by the stouter form, blacker surface and very broad white markings. The last dorsal plate, exposed beyond the elytra, has a transverse series of four long slender spicules. Cicindela provensis n. sp.—Form and markings as in oregona, the entire surface above and beneath deep blue, sometimes with faint sericeous reflection on a part of the elytra; head very moderate, the labrum white (<7), the base and tip blackish (9); surface finely, densely strigose, nude, except a small anterior cluster of sete at each side; prothorax very moderate, transversely obtrapezoidal, finely, densely rugulose, greenish, the deep sulci dark blue; elytra slightly inflated posteriorly, the markings as in oregona, the punctures very dense, rather fine and only moderately or feebly asperulate. Length (co @) 11.0-12.5 mm.; width 4,3-5.2 mm. Utah (Parowan and Provo Cafions). Five specimens from Mr. Spalding. Quite distinct in coloration from oregona and varying a good deal in size. Cicindela provensis ssp. mormonella nov.—Relatively narrower and more parallel than in provensis and of an intense uniform green color, metallic bluish, or in part green, beneath; markings similar and as in oregona, the upper surface subopaque; labrum wholly white, or with a median apical piceous spot in the female, densely strigilate; front bright green, sometimes cupreous medially and near the eyes; prothorax only feebly obtrapezoidal, sculptured and sulcate as in oregona; elytra closely, strongly and asperately punctate throughout. Length (o@ 2) 10.0-11.5 mm.; width 4.2-4.8 mm. Utah (Eureka, Provo Cafion, Parowan and Vineyard). Six specimens. Mr. Spalding. Distinguishable from oregona by its vivid green color and from provensis in color and in its more rectilinearly parallel and more coarsely, asperately punctate elytra. 16 MEMOIRS ON THE COLEOPTERA Cicindela provensis ssp. nephiana nov.—Parallel, form nearly as in provensis but still narrower, coppery green above and bright blue beneath, rather flatter; head green, bright cupreous along the middle and near each eye, strigilate as in provensis and with similarly few setz at each side; prothorax as in oregona but bright cupreous-green, the deep sulci blue; elytra with white markings as in oregona, the punctures coarse and asperate but becoming fine and sparse internally toward base. Length (co) 11.8 mm.; width 4.5 mm. Utah (Parowan). Spalding. To be distinguished from either of the two preceding by the fine sparse punctures toward the scutellum, and by two regular rows of very coarse punctures lying within the longitudinal impression near the humeri. This form is very closely related to scapularis. Cicindela oregona ssp. oregonella nov.—Body much smaller and narrower than in oregona and of the same uniform coloration but more black than brownish above, blue beneath, with parts of the sterna and the entire prosternal side-pieces bright coppery; labrum bilobed medially; front minutely and densely rugulose, with a few short hairs laterally; prothorax as in oregona, the markings of the elytra similar but much reduced, the outer subapical spot minute, the median elbowed band very fine. Length (oc) 10.7 mm.; width 4.4 mm. Utah (Deer Creek, Provo Cafion). One specimen. This is smaller than any other species of the repanda group, excepting wntjuncta, which is very small and narrow, not closely related to repanda and of fully specific value. A considerable series from various parts of Utah seems to repre- sent a very feebly differentiated race of maricopa, and, of sterope I have a large series from Utah and Washington State. The form recently described by Mr. Carr under the name edmontonensis proves, from a cotype communicated by the author, to be completely identical with bucolica. Two specimens from Utah have almost exactly the size and peculiar outline of ovalipennis, but one of them is entirely of a bright green color. The name semipicta seems to be preoccupied and I would there- fore substitute lineoscripta (n. n.) for it, as itis decidedly different from dorsalis in many ways. Cicindela pacifica var. nevadiana nov.—In the notably peculiar subobliter- ated ornamentation of the elytra, this form almost exactly resembles pacifica, the exact status of which is not definitely known, but it is of much smaller size and narrower build, the coloration similar, the abdomen bright yellowish-testa- ceous; the anterior male tarsi have the three basal joints scarcely thickened, excepting the third, which is a little more than twice as long as wide. Length (@) 10.3-10.5 mm.; width 3.7-3.8 mm. Nevada (Las Vegas). Mr. Spalding. Two specimens. The elytra are more parallel and rectilinear at the sides and not so inflated posteriorly as in pacifica. Brightly marked specimens, corresponding to hemorrhagica, are also found at Las Vegas. AppITIOns TO NORTH AMERICAN COLEOPTERA 17 CARABIDE Elaphrus Latr. The following species is allied to cicatricosus Lec.: Elaphrus rhodeanus n. sp.—Moderate in width, convex, polished, bright geneous above, feebly cupreous beneath, the abdomen black; legs obscure, the femora bright metallic blue; head with rather small but deep sparse punctures, the middle of the front tumid and bearing a distinct foveiform impression; eyes very large; on a line through their middle separated by much less than twice their width viewed dorsally; antenne slender, black, feebly cupreous: prothorax short, a fourth or fifth wider than long, the strongly arcuate sides deeply con- stricted before the base; median line acutely impressed in median third of the length, with deep divaricate impressions from its anterior limit and a large transverse impression at its posterior limit; disk with a deep circular fovea on the median transverse line near outer fourth and two much smaller near the median line; elytra two-fifths longer than wide, the very large fovee—in the usual positions—very deep, each with two strong arcuate tumid bluish lines, open before and behind, enclosing strong dense punctures, the intervals between the fovee strongly convex, smooth and polished, with only very few moderate scattered punctures; prothorax beneath with coarse and widely separated punctures. Length (2) 8.0mm.; width 3.0 mm. Rhode Island (Boston Neck). ‘Differs from cicatricosus in its more abbreviated form, much shorter prothorax, clearly incised median pronotal line, large lateral pits and more elevated and smoother interstitial spaces of the elytra. Elaphrus bituberosus n. sp.—Rather narrow, convex, shining and obscure cupreous, except in the fovee; head green, finely, densely punctate, with a feeble transverse ridge between the eyes; antenne rather short and thick, blackish; prothorax equal in width to the head, the sides not prominently though distinctly arcuate, moderately and obtusely constricted near the base, nearly as long as wide, almost evenly convex, finely, very closely punctate, bronzed, with a green streak near each side basally; median line feebly impressed, having apically a large elongate tumidity and, near the base, a small strong shining tubercle; elytra nearly one-half longer than wide, feebly inflated except basally, the usual foveee deep and finely, very densely punctate, red-brown, each with a minute shining central tubercle, the interspaces rather convex, more minutely but not so densely punctulate, a subsutural and more posterior discal spot polished and less punctured; prosternal parapleura finely, densely punctate; femora bright steel-blue, pallid basally, the tibiae subpallid, dark at tip and the tarsi blackish, the anterior with the first three joints dilated in the male. Length (o) 6.5 mm.; width 2.75 mm. British Columbia (Terrace). Received from Mr. Frost. This species is not closely allied to any of the forms near r7parius and ruscarius. Elaphrus texanus n. sp.—Somewhat closely allied to ruscarius, but much broader in the hind body, similar in color and sculpture above, but with the more shining green under surface much more coarsely and sparsely punctured; legs slender, pale testaceous, the femora in apical four-fifths on the anterior, or third on the posterior, metallic green; tarsi metallic green; head almost even, finely, densely punctate; antenne moderately long, green basally; prothorax almost as 18 MEMOIRS ON THE COLEOPTERA long as wide, about as wide as the head, the rounded sides obtusely constricted near the base; surface rather finely, closely punctate, with fine acute median line centrally, very feeble divaricate anterior impressions and, on each side, a small deep fovea, also near the base a deep oblique impression; elytra barely more than a third longer than wide, much more than twice as wide as the pro- thorax, inflated, the sides rather sharply sinuate near basal third; sculpture as in ruscarius, but with less shallow fovee and somewhat stronger elevations. Length (2) 6.3 mm.; width 3.0 mm. Texas (Galveston). Easily distinguishable from ruscarius Say by its more broadly inflated hind body and very different sculpture of the entire under surface. Elaphrus spissicornis n. sp.—Moderately ventricose, dull above, convex, bright cupreous in color of the body throughout, the femora, tibiz and tarsi more obscure; upper surface very finely and densely punctate throughout, except the raised polished elytral spaces, which are black, the under surface finely and closely but not so densely punctate, the abdomen nearly smooth; head as wide as the prothorax, the eyes large, the front nearly even in surface; antenne not as long as the head and prothorax, black, not metallic, except feebly at base; very thick; prothorax a third wider than long, prominently rounded at the sides, the latter parallel and straight in basal sixth or seventh; surface feebly impressed medially, carinulate apically, with a very feeble impression at each side of the middle; elytra two-fifths longer than wide, slightly inflated posteriorly, broadly rounded behind, four-fifths wider than the prothorax and not quite three times as long, with three series of raised shining black areas, separated longitudinally by large and feebly impressed, rather well-defined fovee, with large and rather more obscure central areola, having a minute asperity at the centre; polished spaces of the middle series narrow, the others broad. Length 8.0 mm.; width 3.7mm. Utah (Parowan—6o0o0 ft. elev.),—Spalding. Comparable only with Jecontez, but differing in its pale cupreous coloration and stouter antenne; these are thicker than in any other species known to me, the penultimate joints being very little longer than wide. Blethisa Bon. The following species belongs to the multipunctata section: Blethisa hudsonica n. sp.—A little larger and more elongate than multipunctata, shining black, the elytral margins green and the feebly impressed striz rufous, with the fine punctures green; under surface and legs shining black, the upper surface somewhat metallic; head as in multipunctata, the two lateral lines deeper; antenne similar but evidently longer; prothorax nearly similar throughout but less abbreviated, scarcely over a fourth wider than long; elytra similar in general form and unevenly impressed moderate striation, but with the fine strial punctures much more evident and more close-set; legs (&) longer than in the male of multipunctata, the hind tarsi relatively much shorter than the tibiae. Length 10.5-12.0 mm.; width 4.2-4.8 mm. Canada (Edmonton, Alberta). A single pair received from Mr. Carr. Readily distinguishable from multipunctata by its larger size, darker coloration, much less abbreviated prothorax and relatively Appitions TO NORTH AMERICAN COLEOPTERA 19 shorter hind tarsi. From columbica it differs in its slightly longer prothorax, finer strial punctures and much larger elytral fovez, these being as in multipunctata. Nebria Latr. This genus is very abundantly represented in the colder parts of North America and undescribed forms are continually coming to light; the seven following can be easily recognized: Nebria pallidissima n. sp.—Moderately ventricose and convex, shining, pale brownish-testaceous, the legs and antenne still paler; head fully three-fourths as wide as the prothorax, with well-developed and rather prominent eyes; antenne long and very slender, the third joint two-fifths longer than the fourth; prothorax not quite one-half wider than the median length, the inflated but evenly rounded sides becoming parallel at the very sharp basal angles; base four-fifths as wide as the distinctly sinuate apex, having rather blunt projecting angles; transverse im- pressions distinct and with feeble loose punctuation, the latero-basal impressions narrow, elongate and sinuate; elytra three-fifths longer than wide, just visibly posteriorly inflated, with moderately arcuate sides, one-half wider than the prothorax; stri# rather fine but impressed, with moderate and well-separated but distinct punctures, the scutellar rather long, free and distinctly punctate, the third with four impressed punctures; intervals not quite flat; anterior male tarsi with the first three joints moderately dilated, closely, briefly and coarsely pubescent beneath. Length (co 9) 9.0-9.7 mm.; width 3.7-4.0 mm. Washing- ton State (Wawawai). To be placed near diversa Lec., but much smaller and relatively narrower, with the strial punctures less coarse and more widely separated and with acutely rectangular hind thoracic angles. Nebria pugetana n. sp.—Larger, more elongate and subparallel, similar in lustre, coloration and general structure, the head a little larger, with rather more prominent eyes, somewhat more than three-fourths as wide as the prothorax; legs and antenne very pallid, the latter long and notably slender, the third joint a third longer than the fourth; prothorax nearly similar, the hind angles acute, right; elytra longer and wider, more parallel, almost three-fourths wider than the prothorax, differing in the coarser striz, which are barely visibly or obsoletely punctulate. Length (2) 10.0 mm.; width 4.3 mm. Washington State (Wa- wawai). Differs from the preceding in its larger, longer and more oblong elytra, having the punctures of the coarser strie very nearly obsolete; the fourth antennal joint is relatively longer than in the preceding. Nebria townsendi n. sp.—Much larger and broader, shining and pale brown; legs pale, the antenne very pale gradually toward base; surface only moderately convex; head large, fully three-fourths as wide as the prothorax, the eyes some- what smaller but very prominent; antenne long though slightly less slender, the third joint two-fifths longer than the fourth; prothorax larger and broader, nearly three-fifths wider than its median length, formed and sculptured nearly as in pallidissima, but with the lateral margins less broadly reflexed apically; 20 MEMOIRS ON THE COLEOPTERA hind angles sharply rectangular; elytra shorter and much broader, oval and without humeral angle, only two-fifths longer than wide, nearly one-half wider than the prothorax; strie rather coarse, deeply impressed, very feebly and indistinctly punctate, the third with four or five punctures in apical half, the fifth with two or three punctures; intervals broadly convex; scutellar stria long, free. Length (9) 11.0 mm.; width 4.8 mm. Washington State (Port Townsend). This species differs very much from either of the preceding in its larger size, broader form, slightly less slender antenne and different foveation of the deeper elytral strie; from dzversa it differs in the deeply sinuate sides of the prothorax at base, with sharply rectangular angles. : Nebria corvallis n. sp.—Form and structure nearly as in oregona, but narrower, shining black, the anterior parts feebly picescent, the legs piceous; head about three-fourths as wide as the prothorax, with moderate but remarkably convex eyes, the anterior impressions feeble and diffuse; antennz piceous, slender, the third joint nearly one-half longer than the fourth; prothorax a little over one-half wider than long, moderately inflated, with evenly rounded sides, these oblique and straight in basal half to the very sharp basal angles, which are notably more than right; surface smooth, the lateral impressions in basal two-fifths and transverse ante-basal impression all deep and very feebly rugulose; anterior impression distinct, the median line broadly, deeply impressed; elytra nearly two-thirds longer than wide, very slightly wider posteriad; striz deeply impressed, rather coarsely but feebly punctate, the third feebly tripunctate, the two posterior punctures more approximate; anterior male tarsi with the first three joints very moderately dilated, clothed beneath as usual. Length (o) 10.0 mm.; width 4.0 mm. Oregon (Corvallis). Distinguishable from oregona by its slightly smaller size, notably narrower form, smaller and very much more convex eyes and several other features. Nebria curtulata n. sp.—Oblong, only feebly convex, shining black, the elytra feebly picescent, the pronotal sides nubilously and feebly pallescent; legs and antenne piceous; head barely two-thirds as wide as the prothorax, with well- developed convex eyes, the anterior impressions deep and rounded; antennz slender, the third joint a third longer than the fourth; prothorax short, rather more than three-fourths wider than long, the rounded dilated sides convergent and gradually distinctly sinuate posteriad, the angles right and sharp; transverse ante-basal impression deep, with the bottom punctate, the lateral impressions very short, the subapical deep, obtuse and angulate, with the apical surface feebly punctulate; im#ressed median line fine; elytra parallel, three-fifths longer than wide, about a third wider than the prothorax; striz shallow, unevenly and rather indefinitely punctate, the third with one fine and three strong punctures; anterior male tarsi with three rather well-dilated joints. Length (792) 85 mm.; width 3.3-3.5 mm. Labrador (W. St. Modest),—Sherman. The three specimens of this species were mixed in my series with labradorica, but it is a smaller, shorter and flatter form, with shorter and much more transverse prothorax, and could not fail to be recognized when properly segregated. ADDITIONS TO NORTH AMERICAN COLEOPTERA Zi Nebria hippisleyi n. sp.—Moderately broad and slightly convex, shining, the body and legs piceous; head three-fourths as wide as the prothorax, with moder- ate but very convex eyes, the anterior impressions large, very shallow and indefi- nite; antenne long, slender, testaceous, the third joint two-fifths longer than the fourth; prothorax not quite one-half wider than long, the rounded sides gradually oblique posteriad, nearly straight, becoming only just visibly sinuate and only very near the sharp angles, which are scarcely more than right; im- pressions broad and shallow, only feebly punctulate, the latero-basal narrow, oblique and deeper; median line fine; elytra very feebly inflated posteriorly, three-fourths longer than wide, nearly one-half wider than the prothorax; striae rather fine, shallow, finely, very indefinitely punctulate, the third with five or six small impressed punctures; first three joints of the anterior male tarsi very moderately dilated, the first as long as the next two. Length (co) 11.0 mm.; width 4.5 mm. British Columbia (Terrace). The single specimen was sent to me by Mrs. W. W. Hippisley; it represents a species allied to transversa, but with rather smaller and more prominent eyes, smooth or much less punctate apex and base of the pronotum and especially in having the oblique thoracic side margins very much less sinuate, also in the piceous legs. Nebria fragilis n. sp.—Shining, black, the tibia and tarsi blackish-piceous; head two-thirds as wide as the prothorax, smooth, shorter than wide, the eyes prominent; antenne very slender, obscure rufous, evidently more than half as long as the body, the fourth joint three, the fifth four, times as long as wide; prothorax very nearly one-half wider than long, the sides broadly arcuate, con- verging moderately posteriad, becoming parallel in basal sixth or seventh, the basal angles right and sharp; sides somewhat widely reflexed and punctulate, the base loosely punctate; lateral basal impressions oblique and distinct; trans- verse impressions almost obsolete, the median incised line distinct, biabbreviated; elytra three-fourths longer than wide, widest posteriorly, obtusely rounded at apex, a third wider than the prothorax, smooth, the striae rather fine, impunctate, the third with three small punctures; intervals nearly flat; legs very slender, the hind tarsi longer than the tibie; first three joints of the anterior male tarsi very moderately dilated. Length (o) 8.5-8.8 mm.; width 3.4-3.6 mm. Utah (North Fork, Provo Cafion),—Spalding. Two male specimens. This small delicate species may be placed near arkansana, but is obviously broader in outline, with smooth and not punctulate striz and somewhat less narrowly reflexed sides of the prothorax. Mr. Spalding collected a large series of a Nebria, which may be called trifaria Lec., but if this is true the description of Leconte is rather inaccurate. Tvifaria, which was taken in American Fork Canon, Utah, is said to have the head, with eyes, scarcely narrower than the prothorax, while in the Utah specimens taken by Spalding at North Fork, Provo Canon, the head, with the eyes, is often only three-fourths as wide as the prothorax. Of virescens Horn., I have a single example from Philomath, Oregon; it is larger and less abbreviated than brevis Csy., but of the same coloration; the prothorax is much less transverse as inferrable indeed from the original description. to i) MEMOIRS ON THE COLEOPTERA Irichroa Newm. The form described below seems to be allied closely to andrewst: Irichroa andrewsi ssp. refiexa nov.—Strongly ventricose and convex, shining and very deep violaceous-blue, the legs and under surface black; head nearly similar in structure but distinctly more than half as wide as the prothorax, the latter fully as long as wide, the sides angulate at anterior two-fifths, thence rounded to apex and oblique and straight to base, which is minutely emarginate at the middle, the basal angles broadly rounded; side margins broadly and strongly reflexed, the setigerous tubercle at the angulation conspicuous; surface sculptured much as in andrewsi; elytra oblong-oval, coarsely, deeply and closely striato- punctate, the intervals subeven throughout, a few posteriorly bearing coarse punctures. Length (2) 21.0 mm.; width 8.8 mm. North Carolina (Black Mts.). Beutenmiiller. Larger, stouter and more blackish than any of the series which I have referred to andrewsi, and especially with broader head and longer prothorax; the sides of the prothorax are conspicuously reflexed when compared with most of the forms in Irichroa. Of amplicollis I now have two examples; the female has the prothorax relatively a trifle smaller than in the male type, but of almost identical outline throughout. Bembidion Latr. A considerable number of new species and subspecies belonging to this unwieldy genus have appeared from time to time as follows —many of them taken by Mr. Nunenmacher: Bembidion (Odontium) tacom@ n. sp.—Bodvy elongate-oval, rather convex, shining, bright cupreous, the pronotum gradually duller toward the sides, the sides of the elytra and two large quadrate impressed inner spots on each dull greenish and granulose; head feebly shining, narrower than an elytron, the lateral grooves deep; antenne slender, black, non-metallic; prothorax but little shorter than wide, the parallel sides broadly arcuate, constricted near base, the angles everted and sharp though right, not carinate; lateral basal foveze moder- ate but deep; stria coarse, deep and almost entire; elytra three-fifths longer than wide, nearly three-fourths wider than the prothorax, the parallel sides nearly straight, rounding basally; strie distinctly and closely punctate, the third and fourth most widely separated, the latter but feebly sinuose; under surface with feeble greenish-metallic lustre, the slender black legs feebly metallic, the femora not paler at base. Length (co) 5.8 mm.; width 2.25 mm. Washington State (Wawawai). Allied to hesperium Fall, but larger and more elongate and differing greatly in the coloration of the legs, the femora in that species being pale, gradually black distally. Bembidion (Odontium) zephyrum ssp. tristiculum novy.—Form, outline and general characters nearly as in zephyrum, but dull black and without any form AppITIONS TO NORTH AMERICAN COLEOPTERA 23 of metallic lustre throughout; head large, very nearly as wide as an elytron; prothorax very short, fully four-sevenths wider than long, deeply constricted near the base, the sides thence diverging to the sharp angles, which are however right; surface polished, deep black, gradually opaque toward the sides and at base; elytra three-sevenths longer than wide, the lustrous and opaque parts as described in zephyrum, without any differences in coloration, the fourth stria not distinctly sinuous. Length (co) 5.7-5.85 mm.; width 2.45 mm. Southern Oregon,—J. F. Kemp. The types of this form served as the basis of my conception of sephyrum Fall, described from Humboldt Co., Calif., but it seems to differ not so much in coloration—as the types may have the unnatural black condition occasionally met with in this subgenus and Ochthedromus—as in the shorter and laterally more deeply constricted prothorax. It differs from carinula Chd. in the less abrupt constriction before the basal thoracic angles and in the longer antenne. Bembidion (Odontium) marginosum n. sp.—Body broad and oblong, broadly convex, blackish, the densely granulose areas as in zephyrum, but dark green, _each surrounded by a fine cupreous border, the non-granose parts of the elytra ‘distinctly embossed, smooth, but not highly polished and nearly black in color; head short, distinctly narrower than an elytron, the antenne slender, black and non-metallic; mentum tooth truncate, convex, long and rectilinearly parallel (7), or shorter, broader and less parallel (2); prothorax not quite so short as in the preceding though evidently somewhat more than one-half wider than long, the sides only feebly and broadly constricted near base, becoming feebly divergent; surface with loose transverse rugulation, a small part of the basal margin at the middle more closely, longitudinally strigose; elytra oblong, three-sevenths ( 2 ) or nearly one-half (co) longer than wide, the fourth stria but feebly sinuose; discal spots very large; under surface shining, with feeble greenish lustre, the legs black, the femora pale at base. Length (@@) 5.85-6.25 mm.; width 2.45-2.75 mm. California (Del Norte Co.). Nunenmacher. This species is rather closely allied to zephyrum, but is somewhat larger and with the impressed granulose elytral areas all surrounded by a narrow bright cupreous border. I cannot perceive that the reflexed side margins of the pronotum are wider anteriorly or with the surface there subexplanate; just within the basal thoracic angles there is a very short fine carinule, the basal impressions small. Bembidion (Odontium) carrianum n. sp.—Rather broadly oblong, the minutely granulato-reticulate regions of the elytra as in zephyrum, opaque and green, not at all margined, the smooth shining areas slightly embossed and du!] cupreous; under surface dark polished green, the legs metallic black, the femora rather abruptly pale in nearly basal half; head opaculate, almost as wide as an elytron, the dark antenne very slender; prothorax one-half wider than long, the arcuate sides finely and equally reflexed, moderately sinuate at base; surface with loose transverse rugule, shining, subcupreous, gradually opaculate laterally but not at base; elytra not quite one-half longer than wide, somewhat over one-half wider than the prothorax, oblong; strie finely, closely punctate, the fourth strongly 24 MEMOIRS ON THE COLEOPTERA sinuate at basal fourth, the fifth interval just behind the middle, scarcely more than one-half as wide as at the sinus. Length (@ @) 5.0-5.8 mm.; width 2.15- 2.45 mm. Canada (Edmonton, Alberta),—F.S. Carr. Three specimens. A very interesting and distinct species of the zephyrum type, but with a sharply marked sinus in the fourth elytral stria opposite a marked dilatation of the fifth interval. The mentum tooth in the female type is narrow, with feebly oblique sides and truncate apex. Bembidion (Ochthedromus) ferreum n. sp.—Body short, moderately convex, slightly shining, strongly micro-reticulate, greenish-black, more or less cupreous in the pronotal impressions, smooth beneath, the legs greenish-metallic, the coxe pale; head not quite as large as in bifossulatum, as wide as an elytron, three-fourths as wide as the prothorax, opaculate, with moderate grooves, the eyes notably large; antenne long, wholly black, the medial joints two and one- half times as long as wide; prothorax as in bifossulatum but not so shining; elytra broader, barely one-half longer than wide, parallel, the sides rounding at base, broadly rounded behind, the strie broadly and strongly impressed, strongly and closely punctate, entire, the fovee very large—just before the middle and near apical fourth. Length (2) 7.0 mm.; width 3.0 mm. Utah (Iron Co.). On comparing the female type with the female of bzfossulatum, it is to be noted that ferrewm is much broader in form, with less slender but somewhat longer antennz and coarser and more im- pressed elytral stria. The mentum tooth is oblique at the sides, evenly convex and with the truncate apex somewhat binodulose, while in bifossulatum, though similar in outline, it is convex axially but not apically and has the apex more evenly truncate. In Hydrium levigatum Say, there seem to be two slight modifi- cations, perhaps depending to some degree on the habitat—whether to the east or west of the Appalachians. All of my material is from various sections to the west of the mountains, but my only Pennsylvania specimen—a male—is apparently rather below the average of the western examples and has a different prothorax; I therefore venture to call attention to these differences as follows: Bembidion (Hydrium) levigatum ssp. delawarense nov.—Similar to /evigatum in every way, except that the body is slightly narrower and the prothorax barely one-half wider than long; in /evigatum it is always distinctly more than one-half wider than long. Length (co) 5.7 mm.; width 2.2 mm. It never occurred to me before to notice that virtually all my material in /evigatum was taken west of the Appalachians. The slight differences that appear are observable, however, in many other species of wide distribution, the mountains evidently having a noticeable effect as a barrier affecting specific evolution. Bembidion (Eudromus) edolatum n. sp.—Oval, convex, highly polished, black, strongly «neous, bluish along the sides, black beneath, the legs black; AppiTions TO NORTH AMERICAN COLEOPTERA 25 head moderate, rather narrower than an elytron, with large but only moderately convex eyes, the two frontal channels narrow; antennz black, the first joint testaceous beneath, the medial joints slightly over twice as long as wide; prothorax very nearly one-half wider than long, the parallel sides broadly, very moderately arcuate, becoming gradually straight and parallel for a considerable distance before the right basal angles; apex very feebly sinuate; impressions obsolete, the stria extremely fine, not entire; basal foveee smooth, rather long, linearly impressed, the carina somewhat long and strong; elytra oval, three-sevenths longer than wide, barely a third wider than the prothorax; strie very fine, unimpressed, not entire, only the first four and base of the fifth evident as series of very fine separated punctures; foveze small and very feeble, on the third interval near the third stria. Length (7 9Q) 4.6-4.8 mm.; width 1.7-1.85 mm. Minnesota (Duluth). Three specimens. This is the species that in my revision I assumed to represent nitidum Kirby. At that time I had not seen the original description of Kirby, but lately have acquired the descriptions of the Insecta of the Fauna Boreali-Americana, edited by the Entomological Society of Ontario, and there I find under nitidum, the length of 3.2 lines (6.4 mm.) given for that species, which of course makes the identity of edolatum with nitidum impossible. This length of body coincides with that of obliqulum Lec., which, as formerly maintained, therefore becomes a synonym or variety Of nztidum. I have a large series of this species from Washington State to northern California, one specimen of which—from Josephine Co., Oregon—is much broader than any other, with somewhat larger head and longer antenne, the medial joints of which are three times as long as wide to rather more; this variation may be called B. josephineum (n. var.); it is 6.65 by 2.5 mm. in dimensions. Bembidion (Lionepha) perbrevicolle n. sp.—Oblong, moderately convex, highly polished, black, with very feeble metallic lustre, the legs nearly black, the reflexed elytral margins pallid posteriorly; head smooth, as wide as an elytron, the lateral grooves distinct; antenne blackish, about half as long as the body, the medial joints fully twice as long as wide; prothorax short, fully one-half wider than long, the rounded sides oblique from about the middle, not sinuate basally, the hind angles sharp and about right; surface very smooth, the transverse impressions very feeble, the fine stria extending between them; lateral basal impressions large and deep, the carina fine but distinct; elytra oblong, parallel, about one-half longer than wide, not quite one-half wider than the prothorax; strie fine and feebly impressed, with fine but distinct and well-separated punc- tures, obsolete near the apex, the fovee near basal and apical third. Length ( 2 ) 3.4 mm.; width 1.25 mm. California (Placer Co.). Allied to seclusum but smaller, with much shorter prothorax, less metallic lustre, pale posterior elytral side margins and numerous other differential characters. Bembidion (Lionepha) improvidens n. sp.—Body notably small, not very convex, slightly flattened on the elytra inwardly, polished black, with scarcely 26 MEMOIRS ON THE COLEOPTERA metallic lustre, the legs black; head fully as wide as an elytron, smooth, with deep grooves; antenne piceous, slender, the fifth joint two and one-half times as long as wide; prothorax not quite one-half wider than long, the arcuate sides oblique posteriad, becoming gradually and feebly sinuate toward the sharp right angles; surface very smooth, the anterior impression fine but evident, the posterior feeble, the stria deeply impressed, ending at the base and anterior impression; basal impressions large, shallow and opaque, the carina fine but distinct; elytra oblong, parallel, obtusely ogival in about apical third, a little more than one-half wider than the prothorax, without pallid reflexed edges, the striz very fine but sharply distinct, equal and perfectly entire, impunctate, the fovee small, near two-fifths and four-fifths. Length (o) 3.5 mm.; width 1.23 mm. California (Placer Co.). Not at all closely allied to any other species, but it may be placed near the preceding, differing in many ways, such as the narrower prothorax and finer entire and impunctate strize; these striz are much finer than in any species of Wicromelomalus. Bembidion (Trechonepha) expansipenne n. sp.—Form ventricose, moderately convex, shining black, with blackish-piceous elytra, the legs blackish, very slender; head smooth, with broadly impressed grooves, much narrower than an elytron; antenne slender, blackish, distinctly more than half as long as the body, the medial joints nearly three times as long as wide; prothorax relatively narrow, only a fourth or fifth wider than long, the arcuate parallel sides gradually sinuate behind, straight and parallel for some distance before the sharp right angles; transverse impressions very feeble, the stria subentire but deep only between the impressions; basal fovee large, concave and subopaque, the carina distinct and rather long; elytra broadly oval, less than one-half longer than wide, three- fourths wider than the prothorax; striz fine but sharp and entire, impunctate, the fovez strong, just before the middle and near apical fourth. Length (2) 4.8 mm.; width 2.2 mm. California (Siskiyou Co.),—Blaisdell. May be placed near trechiforme, but with relatively narrower anterior parts and broadly oval elytra. It was identified as méklini by Dr. Blaisdell, but does not answer the description of that Alaskan species at all well. Bembidion (Trechonepha) essexense n. sp.—Oblong-suboval, only moderately convex, shining, black, the elytra piceous-black, the legs obscure testaceous, with blackish femora, which are more pallid at apex; head smooth, with rather broadly excavated furrows, much narrower than an elytron; antenne slender, blackish, more than half as long as the body, the medial joints between three and four times as long as wide; prothorax very much wider than the head, nearly one-half wider than long, the strongly rounded sides more oblique in about basal half, becoming only very feebly sinuate nearly at the angles, which are right and sharp; surface smooth, with almost obsolete transverse impressions, the stria fine but deep, only extending between the impressions; basal impressions only moderate, slightly rugulose and sublinear, the carina rather long, distinct; elytra oblong-oval, one-half longer than wide, more than one-half wider than the pro- thorax; strie rather fine but well impressed, entire and very finely and sub- obsoletely punctulate, the fifth more coarsely impressed for a short distance at base; fovez strong, with long distinct seta, at three-sevenths and three-fourths. Length () 3.9 mm.; width 1.5 mm. New York (Keene Heights, Essex Co.). AppiT1ions TO NoRTH AMERICAN COLEOPTERA 27 A single example was sent to me by Mr. Notman under the name simplex Hayw., but there is a recognizable though short and shallow basal sinus at the sides of the prothorax and the base is if anything wider, not narrower, than the apex; the antenne are longer and the transverse pronotal impressions are nearly obsolete, not at all ‘“‘distinct,’’ and the hind angles are right, not ‘‘obtuse.”’ The elytra appear to be more inflated. In typical form simplex occurs in Labrador. This species does not belong near planiusculum. Bembidion (Trechonepha) notmani n. sp.—Oblong-oval, moderately convex, shining, greenish-black, the elytra piceo-testaceous, the legs dark rufous; head wider than long, much narrower than an elytron, the grooves deep and abrupt; antenne long, slender, piceous, with paler basal joint, the medial joints more than three times as long as wide; prothorax nearly one-half wider than long, the parallel sides broadly arcuate, gradually sinuate posteriad, becoming straight for a fifth the length, the angles right and not rounded; surface smooth, with very obsolete transverse rugulosity, the transverse impressions almost obsolete, the impressed stria extending from the anterior to the base, the basal impressions large, slightly rugose, linearly deeper at the bottom, the carina long and distinct; elytra oblong-oval, scarcely more than one-half wider than the prothorax; strie entire, feebly impressed, minutely, closely and indistinctly punctulate, the fifth - broadly impressed at base; fovezw distinct, near three-sevenths and four-fifths. Length 4.3 mm.; width 1.85 mm. New York (Keene Heights, Essex Co.). The single type sent by Mr. Notman is of undetermined sex; it represents a species allied somewhat to the preceding but larger, with broader head and very much less arcuate sides of the prothorax. It was sent to me under the name planiusculum, but it evidently cannot be that species. Bembidion (Micromelomalus) carolinense n. sp.—Depressed, shining, greenish- black, the elytra piceo-rufous; legs blackish, the femora pallid basally; head much narrower than an elytron, the longitudinal impressions opaque and very broadly excavated, the two separated by a narrow shining ridge; antenne blackish, not very slender, more than half as long as the body, the basal joint but slightly paler, the medial three times as long as wide; prothorax nearly one-half wider than long, the parallel sides rather strongly arcuate, gradually oblique behind the middle, becoming feebly sinuate, then straight and parallel in nearly basal fifth, the angles right and sharp; surface finely, transversely rugulose, the transverse impressions almost completely obsolete, the strongly impressed stria extending from base very nearly to the apex; basal impressions large, rugoseand very shallow, the carina long and conspicuous; elytra barely two-fifths longer than wide, fully two-thirds wider than the prothorax, very obtusely rounded behind, the striz impunctate and entire, strongly and broadly impressed, becoming fine and shallow externally; surface flattened internally, the strong fovee near three-sevenths and four-fifths. Length () 3.6 mm.; width 1.6 mm. North Carolina (Black Mts.). One example. This, basicorne Notm., and the following, are the only three species of the present subgenus that are known by me to have been taken near the Atlantic coast; they are peculiarly characteristic 28 MEMOIRS ON THE COLEOPTERA of the Pacific coast fauna. Carolinense differs from basicorne in its smaller size, less slender antennz, less arcuate sides of the prothorax and stronger elytral striz, these becoming obsolete in outer half in basicorne. Bembidion (Micromelomalus) keeneanum n. sp.—Subparallel, depressed, shining black, the elytra with scarcely visible piceous tinge; legs piceous-black, rather short; head about as wide as an elytron, the impressed grooves deep and separated by a broad polished surface; antenne blackish, not paler at base, nearly half as long as the body, the medial joints a little less than three times as long as wide; prothorax slightly less than one-half wider than long, the rather strongly arcuate sides becoming straight and parallel for a short distance at base; surface with a few transverse rugule medially only, the anterior transverse impression fine but rather sharp, the posterior almost obsolete, broadly impressed stria extending only between the two; basal impressions rather smooth, deep and rounded, the carina long and distinct; elytra somewhat more than one-half longer than wide, slightly less than one-half wider than the prothorax, gradually evenly rounded behind; strie deep, broadly impressed, impunctate, fine but dis- tinct externally; anterior fovea strong, near two-fifths, the posterior smaller and at apical fifth or sixth. Length (9) 3.25 mm.; width 1.3 mm. New York (Keene Heights, Essex Co.),—Notman. Distinguishable easily from carolinense by the structure of the upper surface of the head, shorter antenne and other features and, from basicorne, by the distinct outer striation of the elytra, smaller size, shorter and differently colored antenna, smaller size and other characters. Bembidion (Micromelomalus) placeranum n. sp.—Oblong, depressed, polished, deep black throughout, the legs black, rather short; head moderate, scarcely as wide as an elytron, the grooves moderate, widely separated; antenne black throughout, short, distinctly less than half as long as the body, the medial joints scarcely twice as long as wide; prothorax short, four-sevenths wider than long, the moderately arcuate sides oblique and straight posteriorly to the angles, which are minutely prominent; surface feebly, transversely rugulose only very near the impressed stria, which extends only between the subobsolete impressions; basal impressions large, shallow, sublinearly deeper near the base, the carina distinct, moderately long; elytra not quite one-half longer than wide, ogival in about apical third, scarcely one-half wider than the prothorax, the strie rather fine, feebly impressed internally, fine but distinct externally, entire, not distinctly and somewhat unevenly subpunctulate; fovew small, near two-fifths and three- fourths. Length (2) 3.2 mm.; width 1.2 mm. California (Placer Co.). The type represents a species somewhat resembling timefactum, but with broader and relatively shorter prothorax and _ shorter elytra, the latter having the striz less impressed. Bembidion (Trachelonepha) sierricola n. sp.—Notably elongate but with oblong-oval elytra, deep black throughout and shining, the legs black; head distinctly narrower than an elytron, with rather prominent eyes, the grooves deep, separated by a rather wide convex surface; antenne long, four-sevenths as long as the body, entirely black, the medial joints three times as long as wide; ADDITIONS TO NORTH AMERICAN COLEOPTERA 29 prothorax scarcely over a fourth wider than long, the base somewhat narrower than the apex, the distinctly arcuate sides becoming parallel for some distance at base, the angles right and sharp; surface with feeble loose rugulosity, the anterior impression rather sharp and distinct, the posterior subobsolete, the stria subentire but very fine toward apex and base; basal impressions large, rugulose, moderately concave, the carina long, moderate; elytra four-sevenths longer than wide, gradually rounding behind, three-fourths wider than the prothorax, the strie entire, somewhat deeply impressed and subpunctulate, the outer evident though very fine and smooth; fovee moderate, at about two-fifths and four- fifths. Length (2) 4.7 mm.; width 1.6mm. California (Nevada Co.). Much smaller than any one of the other four species of this subgenus and with a smaller head and more oval elytra. Some years ago Dr. Blaisdell sent me a representative each of vandykei and falsum; they were both taken at the same time and place in Humboldt Co., and whether rigorously correct identifica- tions I have no way of proving. At any rate, they are both distinct from electum and extensum respectively, electum differing from vandykei in its broader elytra and larger head, and extensum differing from falsum in its longer testaceous elytra and pallid legs; there are of course many other differences. The group, with discovery of more species, proves to be clearly separated as a subgenus. Bembidion (Peryphus) marinianum n. sp.—Strongly convex, polished, greenish- black, the legs dark rufous; head as wide as an elytron, the grooves rather narrow, the front broadly convex, polished; antenne four-sevenths as long as the body, slender, blackish, the first joint paler, the last unusually long, the medial joints obconic, nearly two and one-half times as long as wide; prothorax fully a fourth wider than long, the base narrower than the feebly sinuate apex; sides strongly arcuate, subparallel for some distance before the basal angles, which are very sharp though slightly more than right; surface very smooth and convex, the stria entire, the impressions feeble; basal impressions linear or oval and very deep, the carina fine, moderate in length; elytra suboblong-oval, not quite one-half longer than wide, scarcely one-half wider than the prothorax, without impressed striae but with series of strong punctures, well spaced and becoming extinct in about apical third; foveee moderate, near basal and apical third. Length (9) 3.7 mm.; width 1.35 mm. California (Marin Co.). Allied to californicum Hayw., of which I have a specimen from Sta. Anna Cafion, one of its typical localities; it is confined to the far southern part of the state and differs from californicum in its much less slender outline, blacker antenne, which are pale only in the first joint and not gradually paler basally, in its broader pro- thorax and in having the elytral series more extended posteriorly. Bembidion (Peryphus) modocianum n. sp.—Convex, polished and deep black throughout, the legs black; head scarcely as wide as an elytron, polished, with moderate grooves; antenne black throughout, slender, half as long as the body, the medial joints between two and three times as long as wide; prothorax very nearly one-half wider than long, the base and apex equal, the sides arcuate, T. L. Casey, Mem. Col. XI, Mar. 1924.—3 30 MEMOIRS ON THE COLEOPTERA becoming very gradually and feebly sinuate basally, the angles somewhat more than right; surface with very feeble rugule medially, the impressions feeble, the stria biabbreviated; basal impressions oval and deep, the carina fine; elytra oblong, parallel, gradually rounding in about apical third, four-sevenths longer than wide, one-half wider than the prothorax; strie@ scarcely at all impressed, becoming fine and subobsolete at apex but entire, the punctures rather strong, moderately separated, the fovee feeble, near basal and apical third. Length 4.0-4.4 mm.; width 1.35-1.55 mm. California (Modoc Co.),—Nunenmacher. Three specimens. This species may be placed near denveranum, but it is larger and broader, with less sinuate sides of the prothorax at base and with larger strial punctures. Bembidion (Peryphus) alpineanum n. sp.—Shining but not so highly polished, black and feebly neous, the legs black, rather short; head fully as long as wide, not quite as wide as an elytron, the front as in the preceding; antenne black throughout, slender but much less than half as long as the body, the medial joints two and one-half times as long as wide; prothorax two-fifths wider than long, the sides only moderately arcuate, gradually and very feebly sinuate toward the basal angles, which are sharp though rather more than right; surface smooth, the impressions almost obsolete, the stria not coarse but subentire; basal im- pressions shallow, opaculate, with a small, deeper sublinear part, the carina fine, feeble and oblique; elytra nearly three-fifths longer than wide, scarcely one-half wider than the prothorax, parallel, gradually rounding behind, the striz equal, entire, moderately impressed and with small and rather close-set punctures, the moderate fovee near two-fifths and three-fourths. Length (9) 4.5 mm.; width 1.6mm. California (Nevada Co.). One specimen. Not closely allied to any other species; it may be placed near the preceding. I have at hand two specimens labeled ‘“‘ Alaska,’’ that seem to be almost complete replicas of my series of nitens, from northern New York; this would be an exceptional breadth of distribution if true. The following belongs to the same group as erosum, acomanum and sarpedon: Bembidion (Peryphus) tuolumne n. sp.—Only moderately convex, shining, blackish-piceous, the anterior parts with feeble metallic lustre, the elytra abruptly pale at apex, the bounding line oblique on each elytron; disk nubilously but very indefinably reddish in about basal half; legs and most of the abdomen very pale; head moderate, with large eyes and rather deep grooves; antenne three-fifths as long as the body, slender, blackish, feebly testaceous basally, the medial joints fully three times as long as wide; prothorax not quite a third wider than long, the base more than three-fourths the maximum width, the sides arcuate, becoming parallel only about at the sharp basal angles; basal impressions coarsely linear, at outer fifth or sixth, the surface thence inwardly very indefinitely im- pressed and punctulate; carina short and fine; anterior impressions shallow, not punctate; elytra fully two-thirds longer than wide, one-half wider than the prothorax, the parallel sides nearly straight; strie coarse, closely punctate; fovez small, near basal and apical third. Length (7) 6.8 mm.; width 2.5 mm. California (Tuolumne Co.). ADDITIONS TO NORTH AMERICAN COLEOPTERA 31 Allied perhaps most closely to acomanum, but narrower and with more impressed thoracic base and more fuscous antenne; it is much more elongate and with less sharply maculate elytra than erosum. + ; The three following species may be placed near @grotus: Bembidion (Peryphus) viridinigrum n. sp.—Highly polished and deep black, with faint greenish-wneous lustre, the legs black; head subtriangular, three- fourths as wide as the prothorax, polished and smooth, the parallel channels deep, widely separated; antenne black throughout, slender, gradually very slightly thicker distally; prothorax rather short, three-fifths wider than long, widest just beyond the middle, the sides rather strongly rounded, gradually very moderately sinuate and oblique toward the basal angles, which are evidently more than right; surface smooth, the transverse impressions feeble; median line deeply impressed, biabbreviated; two latero-basal impressions deep, oblique, the outer carina between a third and fourth the total length; base equal in width to the moderately sinuate apex; elytra oblong, with evenly rounded apex, scarcely one-half longer than wide, three-sevenths wider than the prothorax, having unimpressed series of coarse punctures, obsolete near apical fourth and thence finer, simple impressed stria to the apex; discal punctures strong, on the third stria at two- and four-fifths; side margins throughout narrowly reflexed. Length (co) 4.0 mm.; width 1.4 mm. Washington State (Govan). Near @grotus but broader, with shorter and more transverse prothorax and unimpressed but only slightly less coarsely punctate elytral striation, the discal fovee less widely separated; the head is slightly larger. Bembidion (Peryphus) govanicum n. sp.—Still somewhat broader in form, highly polished and deep black, the legs black; head shorter, wider than long, a little more than three-fourths as wide as the prothorax, the eyes rather more prominent; frontal channels widely separated, somewhat less accurately parallel; antenne nearly similar, black throughout, the medial joints between two and three times as long as wide; prothorax still shorter and more transverse, the inflated sides more strongly rounded, becoming gradually though evidently sinuate toward the basal angles, which are more nearly right; surface and im- pressions nearly similar, except that the outer carina at base is a little shorter; base not quite as wide as the apex, which is much less sinuate than in the preceding and with blunter angles; elytra one-half longer than wide to less, two-fifths wider than the prothorax, oblong, evenly rounded at apex; striae just visibly impressed, narrow and very finely punctulate, the punctules well separated; dorsal fovez very small, at three-sevenths and near four-fifths; tibize and tarsi very slender, somewhat piceous. Length (co 2) 3.9-4.1 mm.; width 1.4-1.55 mm. Washing- ton State (Govan). Two specimens. This species differs greatly from wiridinigrum in its shorter, broader and laterally more strongly swollen prothorax, with less sinuate apex, but especially in the feeble elytral striation, with very minute and loose punctulation. Bembidion (Peryphus) subzrarium n. sp.—Oblong-suboval, rather convex, polished, black, with evident zneous lustre above, the legs dark piceous, very 32 MeEMoIRS ON THE COLEOPTERA slender; head as long as wide, three-fourths as wide as the prothorax, with well- developed and moderately prominent eyes, the narrow deep lateral grooves not quite parallel; antenne only moderately slender, black throughout, the medial joints about two-thirds longer than wide; prothorax short, fully three-fifths wider than long, the subparallel sides almost evenly and moderately arcuate to the basal angles, which are minutely subprominent, scarcely perceptibly and broadly sinuate before the latter; transverse impressions fine and feeble, the slightly biabbreviated median line fine; latero-basal part of the surface rugose though shining, the impression small; carina short, oblique, only a fifth the total length; base just visibly wider than the broadly and moderately sinuate apex, this having slightly blunt angles; elytra rather more than one-half longer than wide, three-sevenths wider than the prothorax, suboval, very gradually rounding behind; striae very fine, not impressed, gradually extinct posteriorly, very mi- nutely, feebly, loosely and almost imperceptibly punctulate; discal fovee very small and feeble, near two- and five-sevenths. Length (2) 3.8-3.85 mm.; width 1.3-1.38 mm. California (Blue Lakes, Alpine Co.). Two specimens. A very distinct species, not closely allied to any other but coming next to the preceding, because of its very feeble sculpture, though having the sides of the prothorax not inflated and strongly rounded as in that species. In the male the elytra are a little narrower and more parallel than in the female, and the elytral striz are somewhat more coarsely impressed and with the very small punctures more distinct—perhaps an accidental character. The species californicum, marinianum and innocens constitute a well-defined group of these small and very polished black species, all of which probably inhabit damp moss, and they are rather difficult to discriminate among themselves. The first differs in having the punctured elytral senes shorter, especially toward the sides, where the series are much less than half as long as the elytra; in the other two the series are not quite so abbreviated and at the sides are fully half as long as the elytra; znnocens differs from marinianum by having the head not so large, the prothorax a little shorter and the serial punctures of the elytra well separated as in the other two, though not quite so coarse. The following species, a new form of the californicum group, has recently been received: Bembidion (Peryphus) speculinum n. sp—Rather narrow, convex, very smooth and highly polished, black with pronounced bright bronze reflection; the legs piceous, with blacker femora; head well developed, somewhat more than three-fourths as wide as the prothorax, the grooves narrow and very moder- ate; antenne three-sevenths as long as the body, black, the medial joints obconic and about one-half longer than wide; prothorax two-fifths wider than long, the arcuate sides becoming parallel in basal fifth or sixth; elytra oblong, not quite a third wider than the prothorax, the strie fine, unimpressed, finely and remotely punctate to slightly behind the middle; fovee very fine and feeble, not distinct. Length 3.2 mm.; width 1.2 mm. British Columbia (Terrace),—Mrs. W. W. Hippisley. One example. ADDITIONS TO NORTH AMERICAN COLEOPTERA 33 Allied to californicum but differing in its bright subzeneous lustre, black antenne, more transverse prothorax and very much finer serial punctures of the elytra. It may be placed near sube@rarium, but is smaller, more parallel and with very different basal parts of the thoracic sides. After the californicum group of these small polished species comes a small group consisting of govanicum and suberarium, having a very short prothorax, with the sides not distinctly sinuate at base and the elytral punctures very minute and barely visible. Another group with similar oblique but barely at all sinuate sides of the prothorax toward base consists of callidum, tritum, egrotum, viridinigrum and modocianum; these have the serial punctures of the elytra distinct to rather coarse. Then finally there is a group also having the striz but slightly abbreviated, but the sides of the prothorax basally are rather deeply sinuate, becoming parallel before the angles; those that seem to pertain to this group, which has nitens as its oldest species, are nitens, scrutatum, actuosum, denveranum, seductum and tractabile, as well as quadratulum Notm. The species of this nitens group are only moderately well differ- entiated among themselves and generally have the strial punctures very small, though somewhat larger in quadratulum; those of the callidum section are similarly rather closely allied among themselves, often having a greenish lustre, but they usually have the strial punctures strong and deep. The two following may be placed near striola Lec., but are much smaller and more slender: Bembidion (Peryphus) angustior n. sp.—Narrowly suboval, shining, black, the elytra dark rufo-piceous, slightly more pallid subapically, the legs testaceous; head fully as wide as an elytron and four-fifths as wide as the prothorax, polished, with prominent eyes and deep grooves; antennz slender, blackish, with the first joint testaceous; prothorax about a fourth wider than long, the arcuate sides becoming rapidly straight and parallel in basal fifth; surface smooth, the anterior impression deep, the posterior feeble, the distinct stria biabbreviated; basal impressions large, oval and deep, subpunctate, the carina fine, distinct, near the margin; elytra oblong-oval, fully one-half longer than wide, one-half wider than the prothorax; strie rather coarse though very feebly impressed, fine, obsolescent apically, elsewhere with well-developed punctures; first fovea distinct, near two-fifths, the second minute, very feeble and near four-fifths. Length (o@) 4.4-5.1 mm.; width 1.65-1.85 mm. California (Del Norte Co.). Differs from striola in its smaller size, much narrower form, still deeper thoracic basal impressions and other characters, and from shastanicum in its coloration and more prominent eyes, among other features. 34 MeEmorrs ON THE COLEOPTERA Bembidion (Peryphus) debilicolle n. sp.—Still smaller and narrower, shining, black, the elytra barely at all picescent but with the pallid sublateral spot near the apex small though conspicuous; legs testaceous; head smaller than in the preceding and with less prominent eyes, not quite as wide as an elytron, the longitudinal impressions broader; antenne black, with testaceous first joint, as slender as in angustior but not so long; prothorax smaller and shorter, more than a fourth wider than long, with less arcuate sides, gradually oblique behind but very gradually so, and just visibly sinuate near the angles; transverse impressions very feeble, the greatly biabbreviated stria deep; basal impressions large, concave, opaculate, deeper at the middle, the carina moderate; elytra oblong-oval, three- fifths longer than wide, nearly three-fifths wider than the prothorax, the strie fine, very moderately punctate, obsolescent apically and but very slightly im- pressed, the foveze near two-fifths and three-fourths, both distinct. Length (fQ) 4.2-4.5 mm.; width 1.4-1.55 mm. Oregon (Lake Co.). Differs very much from the striola type in the shape of the prothorax and obsolescent sinuation of the sides basally, also in the fine striation, finer punctures-of the elytra and much more unequal fovee of the latter. Bembidion (Peryphus) modulatum n. sp.—Form rather narrow, only very feebly ventricose, polished, piceous, with unevenly testaceous elytra, transversely more pallid subapically; under surface rufous, the legs very pale yellowish; head fully as wide as an elytron, thesgrooves broad, deep, the eyes moderate; antenne very slender, blackish, the first joint very pale; prothorax as in striola but relatively larger, the strongly arcuate sides parallel and straight in basal fifth; transverse impressions very feeble, the stria fine, attaining base but not apex; basal fovee large, very deeply concave, deepest at the middle, the carina well developed; elytra oblong-oval, three-fifths longer than wide, rather less than one-half wider than the prothorax, the striz# moderate, almost unimpressed, rather strongly punctate, fine, very feeble and impunctate apically, the distinct equal fovee at two-fifths and three-fourths. Length 4.8 mm.; width 1.85 mm. Oregon (Josephine Co.). One specimen, apparently male. This species is comparable only with shastanicum, but is narrower and has a relatively larger prothorax and more rectilinear sides of the elytra; in coloration throughout it is very nearly similar. Bembidion (Peryphus) exiguiceps n. sp.—Rather ventricose, polished through- out, black, with dark greenish lustre, the elytra more piceous-black, each with a large humeral and subapical nubilous rufous area, the legs rufous: head small, less than three-fourths as wide as the prothorax, with moderate eyes and large deep frontal grooves; antenne missing in the type; prothorax relatively rather small, a third wider than long, the strongly arcuate sides becoming gradually parallel in about basal seventh, the lateral impressions at base rather large and deep, transversely united by the subangulate basal impression, the subapical fine but distinct, the carina rather short and fine; elytra oblong, with parallel arcuate sides, nearly two-thirds wider than the prothorax and three-fifths longer than wide; striz rather fine but somewhat impressed, finely punctate, the fovee just before the middle and before apical third. Length (9) 4.8 mm.; width 1.85 mm. British Columbia (Terrace),—Mrs. W. W. Hippisley. This is a distinct species, comparable with tetracolum Say, but smaller and narrower and with relatively smaller anterior parts, also finer and much less impressed elytral striz. ApDITIONS TO NORTH AMERICAN COLEOPTERA 35 Bembidion (Peryphus) aversans n. sp.—Form oblong-suboval, rather convex, polished; color throughout almost exactly as in /ucidus Lec.; head rather large, fully as wide as an elytron and three-fourths as wide as the prothorax, the eyes moderate in size and prominence; antenne pale, rather long, slender; prothorax a fourth wider than long, the somewhat strongly arcuate sides gradually oblique behind, becoming very gradually shallowly sinuate for some distance basally; surface smooth, convex, the transverse impressions feeble, the moderate stria impressed, biabbreviated; basal impressions broadly lunate, very deep, punctate, the carina long and strong; elytra oblong, oval behind, rather more than one- half longer than wide, one-half wider than the prothorax, convex, the rather coarse and feebly impressed strie obsolete apically, distinctly punctured in about two-thirds, the foveee very moderate, near one- and two-thirds. Length (2) 5.0 mm.; width 1.65 mm. Mexico. Levette collection. Allied to lucidus but narrower, with relatively larger head and smaller prothorax, with the sides not becoming so parallel near the angles. As shown by the large series in my collection, /ucidus occupies the region having northern Illinois, New Mexico, Humphreys Peak, Arizona, Reno, Nevada, and Edmonton, Alberta, as approximate limits; it does not seem to cross the Sierras; it is very abundant in Colorado. Bembidion (Peryphus) urgens n. sp.—Very moderately convex, polished, greenish-black, the elytra black, with a faint pale external cloud near apical fourth, the reflexed margin diaphanously pale apically; legs testaceous; head moderate, scarcely as wide as an elytron, with prominent eyes and deep sulci; antenne slender, piceous, the first joint paler, the medial joints not quite three times as long as wide; prothorax moderate, three-sevenths wider than long, the arcuate sides feebly sinuate behind, becoming parallel gradually toward the angles; impressions feeble, the anterior finely and sharply lineate, the stria impressed, biabbreviated; basal fovee dull, deeply lineate at the bottom, the carina sharp and distinct; elytra rather broadly oblong, gradually circularly rounded behind, fully one-half longer than wide and a little more than one-half wider than the prothorax; stri# moderate, scarcely at all impressed, fine behind and not quite entire, finely, not closely punctate, as usual impunctate behind; fovez near two-fifths and three-fourths. Length (2) 4.5 mm.; width 1.6 mm. California (Modoc Co.). This is a small and distinctly isolated species, which may be placed near consanguineum, but it is smaller, with relatively smaller prothorax and much finer punctures of the elytral strie. Bembidion (Notaphus) concitatum n. sp.—Bembidion ( Notaphus) nigripes Csy., nec Kirby. (Mem. Col. VIII, 1918, p. 92.) The description given under the above reference for nigripes, supposed to be of Kirby, will serve without further amplification. Since this description was written, I have received a specimen of the true nigripes of Kirby from Mr. F. S. Carr, and taken at Edmonton, Alberta, apparently in the region from which the 36 MEMOIRS ON THE COLEOPTERA Kirbyan species was described. It is larger than concitatum from Marquette, Lake Superior, with a larger head and prothorax, and longer, less slender antenna, but is almost identical in coloration and ornamentation throughout. Concitatwm occurs also in Alberta, Washington State and British Columbia. Bembidion (Notaphus) oblectans n. sp.—Rather ventricose and convex, shining, black, the legs yellowish-testaceous, the lustre slightly greenish; elytra broadly piceous basally and at apical third on each, with an even transversely lunate yellow fascia, which is gradually attenuate within and not interrupted by the strie; head very moderate, distinctly narrower than an elytron, slightly alutaceous and with not very deep sinuous grooves; eyes moderate, the antenne slender, blackish, with the first joint pale, the medial joints fully three times as long as wide; prothorax only about a fourth wider than long, the arcuate sides gradually shallowly sinuate posteriorly to the angles; transverse impressions feeble, the stria fine, subentire; basal impressions concave and punctulate, linearly deep at the middle, the carina rather long and strong; elytra oblong-oval, with arcuate sides, more than one-half longer than wide and rather more than one-half wider than the prothorax; strie broadly impressed, distinct but finer apically, the punctures strong and well separated, obsolete apically; fovez just behind one-fourth and at two-thirds. Length (9) 5.2 mm.; width 1.9 mm. Canada (Edmonton, Alberta),—F. S. Carr. The single specimen represents a species somewhat near approxi- matum Lec., as I have identified it, but with more shining surface and narrower, much less transverse prothorax. Bembidion (Notaphus) fortunatum n. sp.—General coloration and shining lustre nearly as in the preceding, but larger and much broader and with nearly black, basally paler metallic femora; the elytra are nubilously piceous basally and each has a fascia of yellowish at apical third, but here the fascia is broken by the short separate lines on the strial intervals; head nearly similar, not as wide as an elytron but larger than in oblectans, the antenne nearly similar, long and slender; prothorax larger, a third wider than long, otherwise somewhat similar, except that the large shallow basal fovea have a deep rounded cavity notably distant from the basal margin; elytra nearly as in the preceding but broader, barely one-half longer than wide and not quite one-half wider than the prothorax, the fovez similar. Length (co @) 5.4-5.7 mm.; width 2.15-2.25 mm. Canada (Edmonton, Alberta),—F. S. Carr. Allied only to the last but differing in its much stouter form, more transverse prothorax, with different basal impressions and more irregular and comminuted posterior pale elytral fasciz. The two following species can be placed just before contristans Gsyas Bembidion (Notaphus) amplipenne n. sp.—Oblong, unusually short and broad, shining, the head and the pronotum more feebly, alutaceous, black, the anterior parts somewhat greenish, the legs black, the elytra each with a well-defined rounded pale spot near the margin at apical fourth; head well developed, three- fourths as wide as the prothorax; eyes large, the frontal grooves deep and broad; antenne slender, black throughout, about half as long as the body, the median ApbiITIONs TO NortTH AMERICAN COLEOPTERA 37 re joints two and one-half times as long as wide; prothorax one-half wider than long, the moderately arcuate sides becoming gradually slightly sinuate toward base; lateral basal impressions large, rounded, near lateral fourth, the carina strong and conspicuous, in basal fourth; transverse impressions obsolete, the median line fine and biabbreviated; elytra oblong, two-fifths longer than wide, rather more than one-half wider than the prothorax, obtusely rounded behind, the sides parallel and arcuate; strie but feebly impressed, rather finely but closely and deeply punctured; foveze near basal and apical third. Length (9 ) 5.0 mm.; width 2.0mm. Utah (Trout Creek, Juab Co.),—Spalding. Easily identifiable by the short broad outline, notably long slender antenne and many other characters; it is not closely allied to any other species. Bembidion (Notaphus) edmontonense n. sp.—Oblong, rather convex, shining, deep black throughout, except an outer transverse spot of yellow on each elytron near apical third; under surface black, the legs piceous; head moderate, shorter than wide, scarcely over two-thirds as wide as the prothorax, the eyes well devel- oped, moderately prominent; frontal grooves narrow, parallel; antenne piceous- black, with pale basal joint, filiform, the medial joints scarcely twice as long as wide; prothorax one-half wider than long, the sides parallel and distinctly, evenly rounded to the basal sinus, thence parallel in basal fifth or sixth, the angles right; base very slightly wider than the apex, which is barely visibly sinuate; anterior transverse impression subobsolete, the median line fine, not passing the subbasal impression; latero-basal impressions rather large and rugulose, the carina about a fifth the total length; elytra oblong, two-fifths longer than wide, two-fifths wider than the prothorax; strie scarcely impressed, with distinct and well-separated punctures, obsolete toward apex; discal foveze behind third and at three-fifths. Length (o") 3.3 mm.; width 1.3 mm. Canada (Edmonton, Alberta),—Carr. Should be placed near amplipenne, but very much smaller and with more rounded thoracic sides. Bembidion (Notaphus) subexiguum n. sp.—Smaller and much narrower than amplipenne, shining, subeneous, black, the legs black; elytra with feeble nubilous pale maculation near apical third; head and prothorax very feebly alutaceous, the former moderate, not quite three-fourths as wide as the prothorax, with well- developed eyes and parallel frontal grooves; antenne a little longer than the head and prothorax, rather slender, black throughout, the median joints about twice as long as wide; prothorax scarcely one-half wider than long, the rather well-rounded parallel sides becoming gradually moderately sinuate posteriad; lateral basal impressions near outer fourth deep and somewhat narrow, the carina strong, in rather more than basal fourth; surface nearly as in the preceding; elytra oblong-oval, not quite one-half longer than wide, nearly one-half wider than the prothorax; strie rather fine, feebly impressed, somewhat finely but closely punctate, the fovee before basal and at posterior third. Length (<) 3.25 mm.; width 1.15 mm._ British Columbia (Terrace),—Mrs. W. W. Hippisley. This species is widely distinct from any other known to me; it is rather insignificant in point of size. Bembidion (Notaphus) contristans n. sp.—Not stout, rather convex, black, with feeble subzneous lustre, alutaceous, the elytra more shining, with a large 38 MEMOIRS ON THE COLEOPTERA marginal pale spot at apical third and another at the apex on each; legs pale; head rather large, wider than an elytron, with well-developed eyes, narrow grooves and a fovea at the upper margin of each eye; antenne slender, as long as the elytra, piceous, gradually testaceous basally, the medial joints more than twice as long as wide; prothorax three-sevenths wider than long, the arcuate sides gradually feebly sinuate very near the basal angles; transverse impressions subobsolete, the stria fine, slightly biabbreviated, the basal fovee deep, sublinear at the bottom, the carina moderate; elytra short, oblong, parallel, with nearly straight sides medially and broadly rounded basal angles, obtusely rounded at apex, less than one-half longer than wide and slightly less than one-half wider than the prothorax; strie feebly impressed, distinctly punctured, fine and impunctate apically but almost entire; fovee very small, near one- and two-thirds. Length (¢@ 2) 3.7-3.8 mm.; width 1.3-1.4 mm. Rhode Island. The type of this species was associated very unsatisfactorily with marcidum in my revision, since it is much smaller and less dilated; a second specimen of marcidum, just received from Long Island, is exactly similar to the type, which is represented by the larger dimensions under the original description and is from the Hudson Valley. The present species may be associated with posticum, but is smaller and with much more abbreviated elytra. Bembidion (Notaphus) haustum n. sp.—Stout, black, only feebly alutaceous and submetallic, the elytra still more shining and piceous-black, pale toward the humeri and toward the sides near basal and apical third, also with small nubilous spots near basal third of the third interval; legs dark rufous; head moderate, scarcely as wide as an elytron, the grooves rather shallow, the superciliary fovee small and rounded; antennz piceous, paler at base, the medial joints long, three times as long as wide; prothorax broad, about one-half wider than long, the arcuate sides gradually becoming but just visibly sinuate very near the angles; impressions broad and shallow, the stria sharp but greatly biabbreviated; basal fovee duller, feebly concave, very deep linearly for a short distance from the base, the carina long and strong; elytra oblong, parallel, with feebly arcuate sides and obtuse apex, not quite one-half longer than wide and rather less than one-half wider than the prothorax; striz# moderate, fully entire, finely punctate, impunctate apically; foveze sharp and asperulate, near third and three-fourths. Length (9) 4.7 mm.; width 1.8mm. California (Alameda Co.). The single type cannot be associated closely with any of the species hitherto described, being broader, with more transverse prothorax and much more elongate antennal joints. It may be placed next to formale in the list. Bembidion (Notaphus) auxiliator n. sp.—Rather stout, black, feebly zenescent, rather shining, the elytra strongly so, not metallic and with a small pale spot at the middle of the base of each, also three small ones along the third interval and others forming lateral fascia at one and two-thirds, the latter much broken; legs pale piceous; head well developed, a little wider than an elytron, the grooves rather deep, the superciliary fovea rounded and deep; antenne long, black, with barely paler basal joint, not very slender, the medial joints obconic and somewhat more than twice as long as wide; prothorax transverse, inflated, the strongly arcuate sides rapidly oblique behind, becoming straight and parallel in basal AppITIONsS TO NORTH AMERICAN COLEOPTERA 39 sixth; impressions subobsolete, the stria entire; basal fovee broadly rugulose, linearly and deeply impressed at the bottom, the carina strong, moderately long; elytra oblong, with feebly arcuate sides and gradually rounded apex, not quite one-half longer than wide and somewhat less than one-half wider than the pro- thorax; strie feebly impressed, rather coarse, entire, distinctly and closely punctured except apically; fovez subasperate, before third and behind two- thirds. Length (@@) 3.4-4.0 mm.; width 1.45-1.6 mm. California (San Joaquin Co.). Differs greatly from conspersum, near which it should be placed, in its broader form, wider prothorax, with much more inflated and strongly arcuate sides and longer and thicker antenna; conspersum is abundant in the coast regions as far as Sta. Cruz and also occurs in San Joaquin Co. Bembidion (Notaphus) accuratum n. sp.—Oblong, short, moderately convex, rather shining, the head subalutaceous, black, the legs piceous, the elytra with yellow vittz in basal third from the third interval outward, shortest on the third, interrupted on the fifth and sixth, also with a subentire arcuate fascia on each at apical third and some feeble marking at the apex; head rather small, scarcely two-thirds as wide as the prothorax, with very moderate eyes and broadly im- pressed parallel frontal grooves; antenna moderate, slender, filiform, blackish, paler basally; prothorax barely one-half wider than long, the parallel sides evenly rounded, straight and divergent in slightly over basal sixth, the angles subacute and sharp; base distinctly wider than the feebly sinuate apex; elytra two-fifths longer than wide, two-fifths wider than the prothorax, the strie entire, moderate, somewhat impressed, moderately and closely punctate; discal fovee small, near basal and apical third. Length (o) 3.4 mm.; width 1.35 mm. Canada (Ed- monton, Alberta),—Carr. Allied to auxiliator but smaller and with relatively much smaller head, also with sharper and deeper lateral thoracic sinuses near the more acute basal angles. Bembidion (Notaphus) semiopacum n. sp.—Narrower than auvxilzator and more ventricose, or with smaller anterior parts, black, the head and prothorax opaque, the elytra shining, maculate almost as in that species, the apex paler; legs piceo-rufous; antenne rather long, black, the first joint pale, the medial joints twice as long as wide; prothorax small, short, nearly four-sevenths wider than long, only slightly inflated, the more moderately arcuate sides gradually and only feebly sinuate toward base; impressions subobsolete, the fine stria subentire; basal fovee large, shallow and rugulose, with narrow deep linear part at base, the carina rather long and strong; elytra with parallel and somewhat strongly arcuate sides, with gradua!ly rounded apex, about one-half longer than wide and slightly more than one-half wider than the prothorax; strie rather coarse, impressed, entire, moderately punctate, impunctate apically, the fovee distinct, near basal third and just behind two-thirds. Length (2) 3.7 mm.; width 1.35 mm. California (San Joaquin Co.). The single type represents a species rather near conspersum but with more prominent eyes and smaller, shorter and much more opaque prothorax than in any other allied species. 40 MEMorRs ON THE COLEOPTERA Bembidion (Notaphus) spissicorne n. sp.—Notably elongate, convex, shining, the anterior parts polished, black, with feeble metallic lustre, which is wanting on the elytra; the latter have on each a small pale cloud externally at third and a narrow irregular fascia behind two-thirds; legs piceous, the femora black; head slightly wider than an elytron, with moderate but prominent eyes, deep and coarse grooves and rounded superciliary fovee; antenne unusually thick, blackish-piceous, the basal joint deep black, the second obscure testaceous, the median joints twice as long as wide; prothorax three-sevenths wider than long, the strongly arcuate sides oblique and straight behind, becoming sinuate for only a very short distance before the sharp right angles; impressions almost obsolete, the stria very fine and subentire; basal fovee very moderate, rugulose, sublinearly deeper centrally, the carina only moderate in length and prominence; elytra elongate-oval, four-sevenths longer than wide, gradually rounding behind, three-sevenths wider than the prothorax; strie# impressed, strong and entire, finely, deeply and closely punctate except apically; fovea moderate, three in number, near third, four-fifths and just behind the middle. Length (9) 5.5 mm.; width 2.0mm. Utah (Belleyue—3400 ft..),—Spalding. This specius is allied to scudderi Lec., and is the only one known to me of the trifoveate section of Notaphus. According to Hayward, the prothorax in scuddert is about one-half wider than long and nearly as wide as the elytra. The obtuse hind thoracic angles of consimile and hagent Hayw. would prohibit comparison with those species, and in henshawi the coloration is entirely different. Ac- cording to Leconte the median thoracic line in scudderi is deep; in spissicorne it is very fine. Bembidion (Notaphus) albertanum n. sp.—Oblong, moderately convex, rather shining, black, faintly greenish; elytra with short pale lines before and behind basal third on the third interval, and a feeble lateral oblique fascia near basal third, also with an external fascia just behind apical third and not extending to the third interval; legs black throughout; head well developed, with the usual frontal sulci and moderately prominent eyes; antenne rather slender, not quite half as long as the body, deep black, the first joint not paler, the medial joints nearly two and one-half times as long as wide; prothorax broad, fully one-half wider than long, the arcuate sides gradually shallowly sinuate toward the sharp right angles; impressions subobsolete, the stria fine, entire; basal fovee dull, deeply and linearly impressed, the carina long and strong; elytra fully four- sevenths longer than wide, parallel, with slightly arcuate sides and rapidly, obtusely rounded apex, scarcely three-sevenths wider than the prothorax; striae fine and scarcely impressed, entire, finely, rather closely punctate except apically; foveze impressed, asperate, rather before basal and behind apical third. Length (72) 4.7-5.3 mm.; width 1.85-2.2 mm. Canada (Edmonton, Alberta),— B.S; Carrs t The four specimens at hand represent a species wholly different from any other known to me; it is allied to migripes in some respects but is much larger. A specimen of Bembidion (Notaphus) suspectum Blais., trans- mitted by the author, shows that it is identical with indistinctum Dej., a common mid-Californian coastal species of larger size than the related forms. AppITIONS TO NORTH AMERICAN COLEOPTERA AI Bembidion (Notaphus) assensum n. sp.—Convex, slightly alutaceous, black, feebly zneous, the elytra each with a small feeble basal cloud, one external near third and another also very indistinct near apical fourth; legs rufous; head moderate, barely as wide as an elytron, with deep sulci and well-developed, moderately prominent eyes; antenne fully half as long as the body, moderately slender, piceous, the basal joint paler, the medial joints fully twice as long as wide; prothorax only a little over a fourth wider than long, widest near the middle, where the sides are most strongly arcuate, gradually feebly sinuate near the basal angles; surface convex, the impressions almost completely obsolete, the stria very fine, entire; basal fovez very small, deep and linear, the carina short and very fine; elytra oblong, with slightly arcuate sides and subcircularly rounded apex, a little over one-half longer than wide and about three-sevenths wider than the prothorax; strie rather coarse, not impressed, obsolete at apex, the punctures strong and widely separated; foveze between fourth and third and at three-fifths. Length (9) 4.25 mm.; width 1.45 mm. New York (near Brooklyn, L. I.). Belongs near argutum, but slightly larger, with more elongate hind body and stronger and more separated strial punctures; it is much more abbreviated than contractum. The remaining species described below under Notaphus belong to the group of very small species, represented by flavopictum, versicolor and egens; they are very numerous and in general seem to be well characterized; vilescans however belongs to the vile group. Bembidion (Notaphus) terracense n. sp.—Shining, black, the elytra mottled with yellow and black, the former predominating, the latter more solid medially and posteriorly toward the suture; head fully three-fourths as wide as the pro- thorax, the eyes large, the impressions long and obtusely deep; antenne black, scarcely as long as the head and prothorax, the medial joints short, scarcely one-half longer than wide; prothorax transverse, three-sevenths wider than long, strongly rounded at the sides, the latter strongly convergent basally, parallel in about basal sixth; basal impressions rather long, the carina short, very near the sides; surface nearly smooth, the transverse impressions very feeble; elytra long, more than one-half longer than wide, not quite one-half wider than the prothorax; striz coarse and impressed, strongly punctate; fovee near one-third and three- fifths. Length (co) 3.25 mm.; width 1.15 mm. British Columbia (Terrace),— Mrs. W. W. Hippisley. Allied to decipiens and of about the same size, but somewhat narrower, with shorter antennal joints, shorter and slightly more transverse prothorax and very much coarser and more impressed elytral strie; the elytral maculation is nearly similar. Bembidion (Notaphus) wisconsinium n. sp.—Form, size and elytral maculation very nearly as in the British Columbian folerans, but more abbreviated, rather shining, greenish-black, the legs dark testaceous; head fully three-fourths as wide as the prothorax, with well-developed eyes and distinct longitudinal im- pressions; antenne distinctly longer than the head and prothorax, black, grad- ually testaceous basally, the medial joints rather more than one-half longer than wide; prothorax short, a little more than one-half wider than long, the base unusually broad for this section, being more than three-fourths the maximum width; sides inflated and rounded, parallel and straight in fully basal sixth; 42 MeEmorrs ON THE COLEOPTERA basal impressions rather short but deep, the carina at some distance from the sides; median line distinct, the transverse impressions very feeble; elytra oblong-oval, scarcely one-half longer than wide, .three-sevenths wider than the prothorax; striz not impressed but with deep and close-set punctures, the fovee near basal and apical third. Length (9) 3.3 mm.; width 1.2 mm. Wisconsin (Bayfield) —Wickham. This species was overlooked in my previous revision of the genus and confounded with decipiens, than which it has an altogether different, more transverse and basally wider prothorax and some- what larger eyes; it is more closely related to the British Columbian tolerans, but differs in its very much shorter prothorax and elytra among other characters. Bembidion (Notaphus) oregonum n. sp.—Smaller than the two preceding, of nearly similar organization, black, shining, non-metallic, the legs black; elytra black, with feeble paler nubilositv near apical third, except toward the suture; head well developed, four-fifths as wide as the prothorax, the eyes rather large; frontal grooves sharply deep, almost parallel; antenne black throughout, long, rather more than half as long as the body, the medial joints obconic and fully one-half longer than wide; prothorax rather short, very nearly one-half wider than long, only moderately inflated, the arcuate sides becoming parallel in basal sixth or seventh; base rather more than three-fourths the maximum width; basal impressions and carina distinct; transverse impressions very feeble; surface smooth and polished; elytra oblong-oval, about one-half longer than wide, two-fifths wider than the prothorax; stri# not coarse, feebly impressed, rather finely and closely punctate; fovea at two- and four-sevenths. Length (92) 2.6-2.8 mm.; width 1.0-1.1 mm. Oregon (Josephine Co.). Comparable only with flavopictum, but smaller and more ab- breviated, with shorter basally somewhat broader prothorax and almost entirely black elytra. A specimen at hand from Nogales, Ariz., seems to harmonize very well with the California examples of flavopictum, thus indicating a more extended range. Bembidion (Notaphus) nogalesium n. sp.—Thoracic base much more con- stricted than in any one of the preceding small species, polished black, the elytra in great part with obscure flavid marking, wanting toward the suture in posterior half; legs blackish; head large, nearly four-fifths as wide as the prothorax, the eyes large and prominent; frontal grooves sensibly convergent, sharply deep; prothorax one-half wider than long or less, the well-inflated sides strongly arcuate, strongly converging behind, becoming subparallel very near the base, which is three-fifths the maximum width; lateral impressions at base elongate-oval, very deep, the carina not distinct; surface smooth, impressed medially near base; elytra oblong-oval, less than one-half longer than wide, two-fifths wider than the prothorax; striae somewhat coarse, evidently impressed, the punctures rather strong; fovez small, near two-sevenths and two-thirds. Length (oc 2) 2.4-2.6 mm.; width 0.8-0.9 mm. Arizona (Nogales, Sta. Cruz Co.). Two specimens. This very distinct species belongs to the Central Mexican group, represented by such forms as zndigens, and also the Arizona demis- sum, but the thoracic base is much narrower than in the latter. ADDITIONS TO NORTH AMERICAN COLEOPTERA 43 Bembidion (Notaphus) vilescans n. sp.—Convex, polished and deep black throughout the body and legs; head well developed, nearly four-fifths as wide as the prothorax, with rather large and prominent eyes; frontal grooves obtusely deep, parallel; antenne slender, longer than the head and prothorax, the median joints two-thirds longer than wide; prothorax two-fifths wider than long, inflated, the sides rather strongly arcuate, parallel and straight in basal sixth or seventh; latero-basal impressions moderate but deep, at an unusual distance from the angles; surface very smooth, convex, the impressions obsolescent, excepting that one very near the base; elytra oval, not quite one-half longer than wide, very nearly one-half wider than the prothorax; stri# unusually fine, scarcely at all impressed, very finely punctate; fovee small, at two-sevenths and three-fifths. Length (9) 2.7 mm.; width 0.9 mm. Utah (Bellevue—3400 ft.). The single specimen of this distinct species is allied evidently to vile Lec., but differs in its larger and more transverse prothorax, rather longer antenne, more inflated and more finely striate elytra and other features. Bembidion (Diplocampa) canadianum n. sp.—Deep polished black throughout, the elytra without paler areas, the legs piceous; form elongate-suboval, convex; head well developed, rather more than three-fourths as wide as the prothorax, with moderately prominent eyes; frontal grooves not broadly impressed, oblique, uniting at apex; antenne not very slender, black, with paler basal joint, the medial joints about one-half longer than wide; prothorax three-sevenths wider than long, the sides strongly arcuate, becoming oblique behind the middle, rapidly parallel in basal sixth, the angles right; base distinctly narrower than the apex, which is transverse, with rather blunt angles; surface with a few ruguliform lines, the median line fine, slightly biabbreviated; latero-basal impression slightly elongate, smooth and close to the short fine carina; elytra oval, one-half longer than wide to less, a third wider than the prothorax, with arcuate sides very gradually rounded at apex; strie# moderate, scarcely impressed, with distinct and slightly separated punctures, subobliterated in about apical third; discal fovee at one-fifth and four-sevenths. Length (@@) 3.0-3.4 mm.; width I.I5-I.25 mm. Canada (Edmonton, Alberta),—Carr. This distinct species may be placed near tersuwm, from Lake Tahoe, but is more elongate, with larger prothorax, having more strongly arcuate sides, the antenne thicker. Theneck(<) isslightly more elongate and the elytral apices less obtuse than in the female. Phrypeus n. gen. At the time of my revision of Bembidion and allied genera, the species described by Hayward under the name Bembidion rickseckeri was unknown to me in nature, but, through the kindness of friends in California, I have since received a series not only of that but of a related more northern species, and careful observation shows that these singular forms constitute a genus, quite distinct from Bem- bidion and named as above. The body in this genus is small, slender, rather depressed, the 44 MeEmorrs ON THE COLEOPTERA head somewhat as in Bembidion but with much smaller eyes and longer tempora as in Lymne@ops. It is difficult to see the mouth structure very well zm situ, but it would appear that the mentum has an even sinuation, without trace of tooth, and that the ligula is flat, corneous, narrow, with straight oblique sides and angularly emarginate apex. No decided sexual peculiarities can be observed in the anterior tarsi, but the fourth maxillary palpal joint seems to be conical in the male and subulate in the female, normally short however in both. The antennae are slender, filiform and coarsely pubescent throughout, nearly as in Bembidion. The prothorax is strongly constricted at base, with the sides straight and slightly diverging from the constriction to the sharp basal angles in fully basal fourth of the thoracic length, the anterior impression nearly obsolete and the posterior deep and coarsely punctate, the basal foveze moderate and deep and the carina obsolete, being fused with the margin, this toward base being thus narrowly double. The impressed and strongly punctate elytral striz are rather abruptly obsolete at apex, excepting the first. On the third stria there are three very minute setigerous punctures, different in nature from the two or three fovee occurring in Bembidion. In Phrypeus rickseckeri, of which I have four specimens sent by Dr. Blaisdell and taken at Fairfax, in Marin Co., the head and prothorax are very deep brown to black in color, but in the following the color is uniform pale testaceous throughout: Phrypeus rutilinus n. sp.—Form slightly more elongate than in rickseckeri and differing in color, as stated above, the elytra piceous at apex and with a wide and vague, feebly picescent median fascia; legs pale; head rounded, somewhat larger than in rickseckeri, though distinctly narrower than the prothorax, the antenne a little longer, nearly three-fifths as long as the body; frontal sulci parallel, coarse and deep, half the entire length from base to frontal margin; prothorax a fifth to fourth wider than long, inflated anteriorly, the stria entire, impressed, generally somewhat dilated through the posterior transverse impres- sion; elytra four-sevenths longer than wide, depressed above, the sides gradually rounding posteriad; strial punctures coarse and impressed, rapidly fine posteriorly, the three fovez so minute that they are observable only under rather high ampli- fication. Length 2.7-3.0 mm.; width 0.9-1.1 mm. Oregon (Josephine Co.). Four specimens. There seems to be considerable sexual difference in the prothorax, this being only very little wider than long in the male and distinctly wider in the female. Lymnzops Csy. The species described by LeConte under the name J/aticeps has a head so nearly equal in width to the prothorax, as testified by the AppiITIons TO NoRTH AMERICAN COLEOPTERA 45 author, as well as Mr. Hayward, that it inspired the name Jaticeps as the most fitting for it. In angusticeps the head is subelongate and only about three-fourths as wide as the prothorax, so that on the merest glance there is great and very striking inequality. Under the circumstances I am compelled, therefore, to reject the conclusions of Mr. Fall (Ent. News, XX XIII, p. 83) as incorrect. Curtonotus Steph. This is a genus peculiarly northern in habitat; the following undescribed species have been received recently: Curtonotus subtilis n. sp.—Oblong-suboval, notably convex and strongly shining, black, the elytra dark brown; legs piceo-rufous, the tarsi deep black; head four-sevenths as wide as the prothorax, with moderate but rather prominent eyes and short linear apico-frontal impressions; antennz longer than the head and prothorax, piceous, gradually testaceous basally; prothorax a little less than one-half wider than long, the sides parallel and evenly, rather strongly arcuate from apex to base, the basal angles obtuse but not rounded; surface smooth, rather strongly, sparsely, punctured basally, the stria deep, subentire, the subbasal impressions very feeble, remote from the base, the obtuse ridge outwardly limiting the scarcely impressed punctured area distinct; elytra three-fifths longer than wide, with feebly arcuate sides, feeble subapical sinus and gradually rounded apex, only slightly wider than the prothorax; strie fine, not impressed, with very moderate punctures, slightly coarser intero-basally, the scutellar stria rather long; male with the anterior tarsi having the three dilated joints gradually narrower. Length (o) 8.5 mm.; width 3.35 mm. This very distinct species may be placed near brunnipennis, but, apart from coloration of the body, it is not at all closely similar, the fine, unimpressed striz and narrower bodily form imparting a very different facies. The single type may possibly be from Labrador, its only label being ‘‘Stupart Bay.’’ The elytra are feebly inflated posteriorly. Curtonotus albertanus n. sp.—Parallel, convex and polished throughout, deep black, the legs black, with piceous-black tarsi, the anterior flavate, especially in the male; head four-sevenths as wide as the prothorax, with notably prominent eyes and narrow frontal lines; antenne barely longer than the head and pro- thorax, testaceous throughout; prothorax two-fifths wider than long, the moder- ately arcuate parallel sides becoming broadly and feebly sinuate toward the sharp right basal angles; stria fine, dilated at base; basal impressions large, closely and strongly punctate, the punctures extending narrowly across the middle; inner part of the impression linear, the outer bounding ridge strong; elytra parallel, nearly two-thirds longer than wide, about as wide as the prothorax, rapidly obtusely rounded behind, the sinuses distinct; striz rather coarse, im- pressed, with more or less convex intervals, the punctures moderate, deep; male with the anterior tarsi well dilated, the first two joints of equal width. Length (#2) 9.7-10.0 mm.; width 3.65-4.0 mm. Canada (Edmonton, Alberta),— F. S. Carr. T. L. Casey, Mem. Col. XI, Mar. 1924.—4 46 MEMOIRS ON THE COLEOPTERA The series at hand is ample and includes also one specimen from Manitoba. Curtonotus gilvipes n. sp.—Elongate, of very moderate width, polished, deep black, the legs pale yellow-testaceous; head nearly three-fifths as wide as the prothorax, the eyes large but much less prominent, very moderately convex; antennz testaceous, a little longer than the head and prothorax, the latter not quite one-half wider than long, the parallel and rather strongly arcuate sides sinuate basally, becoming gradually parallel for a very short distance at the sharply marked basal angles; surface with the anterior impression not obsolete and punctureless as in the two preceding, but evident though feeble and with some fine sparse punctures, the stria strong, obsolete at apex; basal impressions deep, strongly and closely punctate, only feebly binary, the punctures fine and sparse across the basal surface, the outer bounding ridge long, strong and unusually acute; elytra parallel, three-fifths longer than wide, with evenly and feebly arcuate sides and gradually rounded apex, the sinuses short and feeble, a fifth wider than the prothorax; striz coarse and rather deep, coarsely, deeply and closely punctate, with very moderately convex intervals; male with the anterior tarsi only moder- ately dilated, the basal joint with long parallel peduncle. Length (9) 9.6- 10.0 mm.; width 3.65-4.0 mm. Canada (Manitoba). Easily recognizable by the very moderately convex eyes, coarse and strongly punctate elytral striae and other characters as noted. Curtonotus brevipennis n. sp.—Oblong, more abbreviated than in any of the preceding, subparallel, feebly inflated behind, shining, piceous in color, the under surface and legs rufous; head four-sevenths as wide as the prothorax, with moderate but prominent eyes and rather broad deep antero-frontal lines; antenne slender, pale testaceous, not quite as long as the head and prothorax, the latter large, one-half wider than long, the parallel and rather strongly arcuate sides broadly, feebly sinuate toward the very sharp right basal angles; anterior im- pression nearly obsolete but with a few fine punctures, the stria fine, subentire; basal impressions rather large, feebly concave, distinctly binary and with some- what strong but not dense punctures, very few and small medially, the outer bounding ridge strong, acute basally; elytra about one-half longer than wide, slightly though obviously wider than the prothorax, the sides feebly arcuate, gradually rounded behind, with short shallow sinuses; striz not coarse but well impressed and with small separated punctures, the intervals broadly convex and feebly micro-reticulate; scutellar stria long. Length (2) 9.9 mm.; width 3.9 mm. Western Hudson Bay region. One example. A rather broad oblong species, easily to be recognized by the short antennz, sculpture and rather unusually abbreviated elytra. Curtonotus manitobensis n. sp.—Subparallel and rather convex, with unusually elongate elytra, black, rather shining, the under surface black, the legs rufo- piceous; head notably large, nearly three-fifths as wide as the prothorax, with well-developed and prominent eyes, the apical strioles of the front fine; antennz testaceous, scarcely as long as the head and prothorax, the latter rather short, four-sevenths wider than long, the parallel and strongly arcuate sides rapidly sinuate behind and rectilinearly parallel for a considerable distance before the sharp right angles; anterior impression obsolete and virtually impunctate; stria moderate, stronger basally and not attaining the apex; basal impressions subobsolete, strongly but not very densely punctate, binary, the inner impression ADDITIONS TO NORTH AMERICAN COLEOPTERA 47 sharp and rectilinear, almost attaining the base, the outer narrow and deep along the prominent ridge; median part narrowly subimpunctate; elytra long compared with the prothorax, and between a fourth and fifth wider than the latter, nearly two-thirds longer than wide, the parallel sides feebly and evenly arcuate, gradually rounding behind, with broad feeble sinuses; stri# sharp but rather fine, only shallowly impressed, with moderate and well-separated punctures; intervals feebly convex; scutellar stria long. Length (@) 11.5-11.7 mm.; width 4.2-4.6 mm. Canada (Manitoba). The two-specimens agree fairly well but the second is materially narrower than the type, with slightly deeper strie and with the inner linear thoracic impression less prolonged toward the, basal margin, also with the prothorax more nearly as wide as the elytra. Of the above species albertanus and gilvipes may be placed near catenulatus, the former differing in its virtually impunctate elytral striae and the latter in its much less prominent eyes; brevipennts can very well follow gilvipes, being more abbreviated and with more prominent eyes, but manitobensis is not related closely and might follow bowditchi, though having relatively more elongate elytra and sharply linear long inner impression of the pronotum. The following are two additional species of this genus recently received : Curtonotus durus n. sp.—Parallel, convex, moderately shining, black, the legs piceo-rufous; head somewhat elongate, two-thirds as wide as the prothorax, with well-developed prominent eyes and parallel apical strioles; antenne rather long, testaceous, the medial joints three times as long as wide on the narrower side, the third moderately long; prothorax only two-fifths wider than long, the sides broadly, evenly arcuate, feebly sinuate near the basal angles, which are right; base but little wider than the deeply sinuate apex, the latter having very broadly rounded angles; surface with a few transverse ruguliform lines medially, the latero-basal impressions deep, strongly and closely punctate anteriorly, longitudinally substriate, bounded outwardly by a strong carina, excavated along its inner side; elytra two-thirds longer than wide, parallel, with feebly arcuate sides, barely visibly wider than the prothorax; striw rather coarse, less so posteriad, strongly and closely punctate; intervals flat, micro-reticulate but shining. Length (2) 9.7 mm.; width 3.75 mm. Canada (Edmonton, Alberta), —Carr. May be placed near manitobensis but much narrower, with less transverse prothorax and much less sinuate sides of the prothorax basally. Curtonotus biarcuatus n. sp.—Parallel, convex, shining, black, the legs piceous, with paler tarsi, the head nearly as in the preceding, the antenne not quite so long; prothorax also nearly similar, except that it is scarcely over a third wider than long, with more strongly arcuate sides, which are still more shallowly sinuate toward the angles; apex distinctly narrower than the base, with similarly broadly rounded angles but not so evenly sinuate, the middle of the sinus becoming arcuate; surface and impressions throughout nearly as in durus; elytra almost 48 MEMOIRS ON THE COLEOPTERA similar in form and proportions, but somewhat more swollen submedially; striz rather coarse, sharply deep, impunctate except very feebly near the base; intervals feebly convex, similar in sculpture. Length (9) 10.0 mm.; width 4.0 mm. Canada (Edmonton, Alberta),—Carr. Although so similar to durus in most of its characters, this species differs very greatly in the elytral striae, as well as certain other characters mentioned above. Bradytus Zimm.- The following species comes rather close to @qualis, but has a very much smaller head: Bradytus neomexicanus n. sp.—Oblong and strongly convex, deep black and highly polished, the legs black; head small, scarcely over half as wide as the prothorax, the apico-frontal impressions very small, fine and oblique; eyes prominent; antenne slender, testaceous, about as long as the head and prothorax, the latter not quite one-half wider than long, the sides broadly arcuate, straighter and more parallel in more than basal half, the angles slightly obtuse but scarcely blunt; surface very smooth, without transverse impressions, the stria fine; two basal impressions at each side very small and feeble, the inner linear and slightly oblique; surface scarcely at all punctulate; elytra three-sevenths longer than wide, the sides gradually rounding behind about the middle; striz fine but dis- tinct, scarcely impressed and wholly impunctate, the scutellar very fine and fragmentary. Length (oc) 7.2 mm.; width 3.2 mm. New Mexico (Maxwell). One specimen. The anterior tarsi in the male are moderately dilated, piceous, with the first three joints regularly diminishing in width. The first species described below belongs near obsolescens and specularis, but especially the latter; the antenne distally are much thinner than in obsolescens; the second is‘near relictus but with more inflated hind body: Bradytus spaldingi n. sp.—Oblong, convex, polished in the male, black, the prothorax, tibiz and tarsi dark piceous; head just visibly more than half as wide as the prothorax, with notably prominent eyes; anterior frontal grooves linear and oblique; antennz piceous, slightly paler basally, moderately slender, not extending quite to the thoracic base, the medial joints about twice as long as wide; prothorax not quite one-half wider than long, widest slightly behind the middle, the sides evenly and rather strongly arcuate, the hind angles more than right but somewhat sharp; surface smooth, with two deep subequal impressions toward each side basally, inclosing very few fine feeble punctures; median line rather deep, extending from base not quite to apex; elytra only a third longer than wide, very little wider than the prothorax, with slightly arcuate parallel sides and obtusely rounded apex; stria fine but distinct, smooth; anterior male tarsi only slightly dilated, the others slender. Length (co) 7.0 mm.; width 3.3 mm. Utah (Callao),—Mr. Tom Spalding. Differs from specularis, from near Tugson, Ariz., in its more abbreviated form and rather smaller head, with more prominent AppITIONS TO NORTH AMERICAN COLEOPTERA 49 eyes, smoother thoracic base, with deeper and more equal lateral impressions and in the less compressed antenna, among other structures. The antenne of obsolescens are nearly as in specularis, but the body is much more abbreviated, nearly as in spaldingi, though the basal impressions are very much feebler and the punc- tures somewhat more numerous. Bradytus maxwelli n. sp.—Oblong-suboval, strongly convex, with rather inflated hind body, polished black, the elytra (9) faintly alutaceous; legs rufo- piceous; head subtriangular, as long as wide, four-sevenths as wide as the pro- thorax, the eyes moderate and only slightly prominent; anterior strioles deep, long, arcuate and oblique; antenne testaceous, not extending to the thoracic base, the medial joints slightly more than twice as long as wide, the third almost one-half longer than the fourth; prothorax one-half wider than long, the sub- parallel sides distinctly and subevenly arcuate, straighter toward the hind angles, which are sharp though somewhat more than right; base fully a fifth wider than the apex, which is rather deeply sinuate, with slightly rounded angles; surface smooth, without transverse impressions and with fine entire median stria; sub- basal impression just within lateral fourth very deep, oval and with very few punctures, which are wholly limited thereto, the outer fovea small, very deep and postero-outwardly oblique; elytra three-sevenths longer than wide, at the middle of the rather strongly arcuate sides a fourth or fifth wider than the pro- thorax; strie fine, abrupt, finely, loosely and not very distinctly punctulate, the scutellar moderate, free; intervals flat or very nearly. Length (2) 9.0 mm.; width 3.85 mm. New Mexico (Maxwell),—Wade. May be placed near relictus but larger, stouter, more inflated in the hind body, less punctate at the thoracic base and with less prominent eyes, the types of both being the female. Celia Zimm. As shown by the abruptly deplanate sides of the pronotum, the following species may be placed just after Jaxicollis, but it is much smaller and narrower, as well as darker in color: Celia piperi n. sp.—Parallel, only moderately convex, polished throughout and piceous-black above, the entire under surface and legs pale-testaceous; head well developed, nearly four-sevenths as wide as the prothorax, the eyes rather large but only moderately convex; anterior strioles parallel; antenne slender, testaceous, extending somewhat behind the thoracic base, the medial joints between two and three times as long as wide; prothorax nearly one-half wider than long, the sides very finely reflexed, broadly arcuate anteriad, becoming gradually straighter and parallel behind; reflexed margins pallid; surface punctu- late basally, with two feeble lateral impressions, the outer more oblique, the sides abruptly deplanate, except beyond the middle; elytra nearly two-fifths longer than wide, at the middle of the somewhat arcuate sides a little wider than the prothorax; stri# very fine, simple, the intervals flat. Length (2) 6.6 mm.; width 2.9 mm. Michigan (Grayling—near Bay City),—Prof. C. V. Piper. 50 MEMOIRS ON THE COLEOPTERA Easily recognizable by the rather narrow outline, abruptly de- planate sides of the pronotum, very fine elytral striae and by the general coloration of the body. The following four species may be placed immediately after shastanica in the list: Celia vancouveri n. sp.—Oblong, moderately convex, shining, bright neous, greenish-black beneath, the legs black; head very slightly more than half as wide as the prothorax, the frontal strioles very short, oblique; eyes well developed but only of very moderate convexity; antenne barely shorter than the head and prothorax, black, with the first joint testaceous: prothorax about four-fifths wider than long, the sides slightly converging and very feebly arcuate from the base, gradually more arcuate anteriorly to the rounded angles, the basal angles nearly right, not blunt, the puncture in the angle equidistant from base and side and distinct; surface smooth, the stria not deep, biabbreviated; inner basal impressions minute, remote from the margin, longitudinally linear, the outer small, rounded and feeble; elytra three-sevenths longer than wide, parallel, barely at all wider than the prothorax and obtusely rounded behind, with short distinct sinuses; striz very fine but sharp, impunctate, the scutellar long, fine and entire. Length () 7.9-8.7 mm.; width 3.65-3.85 mm. British Columbia and Washington State (Govan and Pullman). Four specimens, the female not at hand. The anterior male tarsi are rather strongly dilated, gradually more so basally as usual and are deep black. Celia olympia n. sp.—Stout, oblong-oval, convex, very shining and bright zneous above, black beneath, the legs black; head slightly more than half as wide as the prothorax, the apical strioles very fine and oblique; eyes well developed but only moderately prominent; antenne somewhat longer than the head and prothorax, black, the first joint rufo-piceous; prothorax fully three-fourths wider than long, the sides nearly as in vancouvert, but parallel basally and with the apical angles not distinctly rounded, the basal angular puncture smaller; surface smooth, nearly as in that species; elytra shorter, slightly wider than the prothorax and but little over a third longer than wide, the parallel sides more gradually rounded in more than posterior half, the apex less obtuse; surface and strie nearly similar, the former more shining and with the median line of the intervals just visibly tumescent. Length (co) 8.3 mm.; width 3.8mm. Wash- ington State (Wilbur). One specimen. Easily separable from the preceding by its more polished surface, more abbreviated contour and more posteriorly narrowed elytra, with the median line of the intervals feebly prominent, in a way never so evident in vancouvert. Celia subsimilis n. sp——Much smaller, oblong-suboval, convex and bronzed above, black beneath, the legs black; head slightly though evidently more than half as wide as the prothorax, the strioles short, more parallel and much broader; eyes moderate, not very prominent; antenne nearly as in the preceding; prothorax shorter, almost twice as wide as long, the sides broadly, subequally arcuate, a little more so apically and not quite parallel basally, the basal angles rather sharp, with distinct included puncture; short inner impression feeble and oblique, AppiTions TO NORTH AMERICAN COLEOPTERA 51 the outer small and scarcely more than a very shallow dent; elytra about a third longer than wide, with parallel and rather arcuate sides and gradually rounded obtuse apex, at the middle slightly wider than the prothorax; strize very fine, the intervals not quite flat. Length (9) 7.2-7.4 mm.; width 3.3 mm. Washington State (Wawawai and Govan). Two specimens. Distinguishable from both of the preceding by the much smaller size, distinctly narrower form and relatively shorter prothorax; the anterior tarsi in the male are deep black and moderately dilated. Celia marginatella n. sp.—Broadly oblong, rather convex, bronzed above, the ninth elytral interval greenish, black beneath, the legs black, moderately shining; head nearly four-sevenths as wide as the prothorax, the eyes rather prominent; anterior strioles short, dilated and subpunctiform; antenne notably short, not as long as the head and prothorax, black, with pale first joint, the medial joints only one-half longer than wide; prothorax four-fifths wider than long, the sides parallel and barely arcuate, gradually so from rather behind the middle to the narrowly rounded apical angles, the basal angles right and sharp, the inclosed puncture small; surface not punctate at any part, the stria fine, more evident basally, not attaining apex, the basal impressions extremely small, feeble and barely traceable; elytra barely a third longer than wide, at the middle very slightly wider than the prothorax, the parallel sides feebly arcuate; apex gradually rounded, with rather deep sinuses; strie very fine, the scutellar not very long; intervals nearly but not quite flat, strongly micro-reticulate. Length (2) 7.5 mm.; width 3.45 mm. Canada (Manitoba). One specimen. Readily identifiable by the rather small size in this special section, and by the notably short and somewhat thick antenne. Celia parallela n.*sp.—Parallel, moderately convex, black and shining, but with scarcely any metallic lustre, the under surface, legs and all the tarsi deep black; head three-sevenths as wide as the prothorax, the eyes moderately prominent; apical strioles small, linear and oblique; antenne slender, as long as the head and prothorax, black, the basal joint testaceous, blackish above; medial joints twice as long as wide; prothorax almost four-fifths wider than long, the sides broadly arcuate, becoming gradually parallel near the base, the angles right and well defined, the inclosed puncture equidistant from base and side; apical angles narrowly rounded; surface nearly smooth; both transverse impressions evident medially, the basal impressions small and subobsolete; elytra almost one-half longer than wide, barely visibly wider than the prothorax, the parallel sides very feebly arcuate, the apex obtusely rounded; striz fine, not at all punctulate, the intervals nearly flat, feebly micro-reticulate; male with the anterior tarsi very moderately dilated.

Length (@) 5.35 mm.; width 2.2 mm. Canada (Manitoba). The elytra in the type are each transversely and deeply indented along the base; presumably this is wholly an accidental deformity, although symmetrical. This species belongs near fragilis, but it is much more abbreviated in outline.

Length (co) 6.5 mm.; width 2.8 mm. Utah (Summit of Parowan Mts.),—Knaus.

Length (2) 6.5 mm.; width 2.8mm. North Carolina (Southern Pines),—Manee. This species should be placed near volatilis, but is slightly larger, with less transverse prothorax, having more feebly arcuate sides and similarly few but finer latero-basal punctures, also larger head and especially longer and more slender hind tarsi. From Hagerstown, Maryland, I have a specimen almost similar to the type of lubrica, except that the elytral striae are coarser and deeper and very much less evidently punctured. Amara Bon. The name acuminata, given by me to a species of this genus in my revision of a few years ago, is preoccupied by acuminata Payk. and I therefore substitute the name acuticauda (n. n.) for the former; it is an isolated species, not at all closely allied to any other and I assume that Paykull’s species is a true Amara. The following species have been received during the past few years, as contributions of several correspondents. ° Of the species here de- scribed only oodiformis, convergens, pullmanit, microcephala, recti- collis, wadei and obliqua have the scutellar stria proceeding from a definite puncture.

Length (9) 7.5 mm.; -width 3.25 mm. New Mexico (Maxwell). One specimen. Easily distinguishable from the last by the smaller head, much shorter antenne and more convex strial intervals, notwithstanding the sex, they generally being more convex in the male. Amara microcephala n. sp.—Oblong-suboval, convex and strongly shining, feebly bronzed above, the under surface and femora greenish-black, the tibie and tarsi rufo-piceous;. head notably small, distinctly less than half as wide as the prothorax, with well-developed and moderately prominent eyes and very short oblique strioles; antenne slender, not quite as long as the head and pro- thorax, piceous, the first three joints and basal half of the fourth testaceous, the medial joints about twice as long as wide; prothorax not quite one-half wider than long, the sides subparallel in basal, rapidly oblique and moderately arcuate in apical, half; basal angles right, with finely blunt tips, the included puncture well developed, more distant from side than base; the apical angles only very narrowly blunt at tip; surface smooth and impunctate, with vestiges of transverse impressions and fine biabbreviated stria; basal impressions feeble but traceable, especially the inner; elytra two-fifths longer than wide, as wide as the prothorax, the sides parallel and faintly arcuate, the apex obtusely ogival; striz rather fine but strong, impunctate, the scutellar with puncture, moderately free; intervals not quite flat; anterior male tarsi rather strongly dilated, the joints not very rapidly diminishing in width. Length (o) 6.4-6.9 mm.; width 3.15-3.25 mm. North Carolina (Southern Pines),—Manee. Three specimens, all males. This species is rather isolated and may be identified readily by the very small head and subimpressed elytral strize, as well as the puncture of the scutellar stria. Amara recticollis n. sp —Oblong-suboval, strongly convex, polished, somewhat greenish-bronzed; under surface and femora deep black, the tibiz and tarsi rufo- piceous; head very nearly though not quite half as wide as the prothorax, with rather prominent eyes; antenne slender, but not as long as the head and pro- thorax, piceous, the first three or four joints testaceous, the medial joints about twice aS long as wide; prothorax long, not quite one-half wider than long and with the long feebly converging sides unusually straight, gradually moderately arcuate beyond about the middle; basal angles right, very slightly blunt, the large puncture twice as far from side as base; apex deeply sinuate, the angles only narrowly blunt at tip; surface smooth and impunctate, the short rectilinear inner basal impression alone visible, the median stria extremely fine, subentire: ADDITIONS TO NoRTH AMERICAN COLEOPTERA ~ 63 elytra two-fifths longer than wide, parallel, at the middle of the very feebly arcuate sides just visibly wider than the prothorax; apex rather obtuse; striz rather fine but sharply incised, impunctate, the scutellar long, free, with anterior puncture; intervals virtually flat; anterior male tarsi distinctly dilated. Length (@) 7.8 mm.; width 3.75 mm. North Carolina (Southern Pines),—Manee. One specimen. This very distinct species may be placed next to microcephala, because of coloration of the body, legs and antenna and presence of a scutellar strial puncture. Amara wadei n. sp.—Smaller, elongate-subelliptic, convex, polished, greenish- black, the under surface and femora black, the coxe, tibia and tarsi piceo-testa- ceous; head small, scarcely half as wide as the prothorax, with moderately prominent eyes and short subparallel strioles; antenne slender, almost as long as the head and prothorax, piceous, the three basal joints pale testaceous, the medial joints between two and three times as long as wide; prothorax long, only three-sevenths wider than long, the sides evenly converging from base to apex and feebly, subevenly arcuate; basal angles right, slightly blunt at tip, the puncture discal, further from side than base; surface very smooth, impunctate, the stria very fine, not entire; basal impressions very shallow and vague, the inner slightly the more visible, though diffuse; elytra fully three-sevenths longer than wide, barely wider than the prothorax, gradually rounding behind from about the middle; stria moderate, deep, impressed, subexarate at apex, impunc- tate, the scutellar free; intervals just visibly convex. Length (2) 6.5-6.7 mm.; width 3.0-3.2 mm. Maryland (Hagerstown),—J. S. Wade. Two specimens. The evenly converging and subevenly, feebly arcuate sides of the prothorax and very shining surface, even in the female, will serve to identify this species whenever found. The following species somewhat resembles wadei in the oblique thoracic sides but it is much narrower and with larger head: Amara obliqua n. sp.—Narrow, elongate-oval, convex, shining, deep black above and beneath, the legs wholly black; head rather well developed, distinctly more than half as wide as the prothorax, with rather large and prominent eyes, the strioles deep, oblique: antenne not quite as long as the head and prothorax, black, the first three joints and base of the fourth pale testaceous, the medial joints distinctly over twice as long as wide; prothorax shorter, slightly more than one-half wider than long, the sides subevenly and very moderately arcuate, not becoming quite parallel basally, the basal angles right, finely blunt at tip, the puncture subequidistant from side and base; surface smooth, impunctate, the stria extremely fine; basal impressions very feeble but evident, small, the inner short, linear, the outer somewhat rounded; apex more shallowly sinuate and with more broadly rounded tips of the angles; elytra as wide as the prothorax, gradually rounding behind, three-sevenths longer than wide, the strie very fine, impunctate, the scutellar widely free; intervals almost but not quite flat, polished. Length (o) 7.3 mm.; width 3.0 mm. British Columbia. One specimen. The anterior tarsi in the male are moderately though very distinctly dilated, and the species is not closely related to any other. Amara inflaticollis n. sp. —Oblong-suboval, convex, polished, bronzed above, the under surface black, the legs obscure rufous throughout; head not quite 64 : MEMOIRS ON THE COLEOPTERA half as wide as the prothorax, with moderately prominent eyes and subobsolete and very oblique strioles; antenne nearly as long as the head and prothorax, piceous, the first three joints and base of the fourth dark testaceous, the medial joints about twice as long as wide—more on the narrow side; prothorax large, not quite one-half wider than long, the sides feebly converging and very moder- ately, evenly arcuate from base to apex, the basal angles nearly right but broadly blunt, the deep puncture slightly further from side than base; apex deeply sinuate; surface smooth, not evidently impressed, the stria fine, impressed; latero-basal regions unevenly and very shallowly impressed, impunctate; elytra parallel, with straight sides and obtusely rounded apex, scarcely two-fifths longer than wide, not quite as wide as the prothorax; strie fine but sharp and rather deep, impunctate, the scutellar moderate, free, somewhat disrupted; intervals flat, polished; anterior male tarsi very moderately dilated, black. Length (<) 6.5 mm.; width 2.7 mm. Canada (Manitoba). The large prothorax, evidently wider than the elytra, absence of definable pronotal impressions and other characters, as stated, will render this species easy to identify. Amara subarctica n. sp.—Oblong, convex, moderately shining, deep black, without metallic lustre; under surface and legs black; head well developed, very slightly more than half as wide as the prothorax, the eyes only very moderately convex, the strioles short, oblique; antennz slender, piceous, the first two joints testaceous; prothorax four-sevenths wider than long, the distinctly arcuate sides gradually becoming straighter and almost parallel basally; basal angles obtuse and blunt, the puncture adjacent to base but remote from side; apex deeply sinuate, with but slightly blunt angular tips; surface smooth, impunctate, with extremely fine stria, the latero-basal impressions moderate, the inner short, deep and finely linear, remote from base, the outer large, rounded and very shallow; elytra three-sevenths longer than wide, barely visibly wider than the prothorax, parallel, gradually obtusely rounded behind; striae very fine, impunc- tate, the scutellar long, free; intervals flat; anterior male tarsi well dilated, the - joints moderately decreasing, the first rather longer than wide. Length (o) 7.9 mm.; width 3.5 mm. Canada (Saskatchewan). This species may be placed near ebenina, but it has the puncture at the thoracic hind angles in very different position. Amara cockerelli n. sp.—Oblong, convex and shining, deep black, with the feeblest possible bronzy lustre; under surface and femora black, the epipleura dark testaceous, the tibiz and tarsi rufo-piceous; head only slightly over half as wide as the prothorax, with prominent eyes and distinctly incised short oblique strioles; antenne evidently shorter than the head and prothorax, slender, piceous, the first three joints and base of the fourth testaceous, the medial joints not quite twice as long as wide; palpi black; prothorax four-sevenths wider than long, the arcuate sides gradually becoming parallel near the base, the angles right and but finely blunt, the distinct puncture very close-set in the angle; apex moderately sinuate, with broadly rounded angular tips; surface smooth, impunctate, with extremely fine imperfect stria, the latero-basal impressions distinct, the inner a short incised line remote from the base, the outer a deep oblique concavity; elytra barely at all wider than the prothorax, only a third longer than wide, parallel, rapidly and obtusely rounded behind; strie very fine, impunctate, the scutellar short, free at both ends in the type; intervals nearly but not quite flat. Length (2) 7.0mm.; width 3.15mm. Colorado (Jimtown),—T. D. A. Cockerell. AppDITIONS TO NORTH AMERICAN COLEOPTERA 65 Allied to convexa Lec., but differing in the entire absence of the characteristic metallic lustre of that species and in its much larger head, among other features. Polita Lec., has an apparently far greater range than convexa, which is a much broader species; polita occurs, according to the material at hand, from Boulder, Colo., to Quebec. It may be added here that /acustrina Csy., also has a wide geographic range— from Lake Superior to British Columbia. Amara breviformis n. sp.—Short, oblong, very convex and highly polished, bright zneo-cupreous, the elytra more. greenish; under surface and legs deep piceo-rufous; head fully four-sevenths as wide as the prothorax, with very prominent eyes and short, not very oblique strioles; antenne not quite as long as the head and prothorax, piceous, with the first three joints testaceous, the medial joints obconic and slightly less than twice as long as wide; prothorax one-half wider than long, the parallel sides almost evenly and moderately arcuate, the greatest width rather behind the middle; basal angles more than right, scarcely at all blunt, the puncture rather close-set to side and base; apex very moderately sinuate, with broadly rounded angular tips; surface nearly smooth, impunctate, with fine stria, the latero-basal impressions moderate, the inner linear and more distinct; elytra barely more than a fourth longer than wide, shorter than in any other species, parallel, with arcuate sides and rapidly very obtuse apex, about a sixth wider than the prothorax; strie fine but deeply incised, impunctate, the scutellar free behind; intervals flat, somewhat concave subapically; anterior male tarsi well dilated. Length (co) 5.7 mm.; width 2.65 mm. Colorado (Boulder),—T. D. A. Cockerell. One specimen. This species is not closely allied to any other, but may be placed among the convexa and polita series. Amara carriana n. sp.—Oblong, convex, polished, obscurely bronzed; under surface and legs deep black, the tibie piceo-rufous; head about half as wide as the prothorax, with only very moderately convex eyes; antenne very nearly as long as the head and prothorax, black, the first two joints and base of the third testaceous, the medial joints fully twice as long as wide; prothorax barely more than one-half wider than long, the sides broadly arcuate, less so and gradually subparallel basally, the angles more than right, obtuse, the puncture strong, remote from side, adjacent to base; width at base somewhat greater than that of the elytral base; apical angles with only narrowly blunt tips; surface feebly impressed and obsoletely subpunctate near apex and along the base, with fine abbreviated stria ending anteriorly in a small punctiform dilatation; latero- basal impressions feeble and linear, the outer oblique; elytra three-sevenths longer than wide, parallel, as wide as the prothorax, rapidly obtusely rounding behind; striz not very fine, broadly and distinctly impressed and distinctly punctured; intervals broadly convex, more distinctly toward the sides; anterior male tarsi well dilated, the joints decreasing but slightly. Length () 7.3 mm.; width 3.1 mm. Canada (Edmonton, Alberta),—F. S. Carr. There is no described species with which this can be in any way closely compared, but it may be placed near subpunctata in the list. 66 MEMOIRS ON THE COLEOPTERA Triena Lec. The species of this genus are of a rather narrow elongate form as a rule, very much as in the aurata group of Celia, but the special modification of the anterior tibial spur seems to distinguish them constantly, and the genus is therefore valid. The three following undescribed species have recently come to light: Trizna lawrenceana n. sp.—Narrowly oblong-suboval, convex, shining, bright bronze in lustre, the under surface and femora black, the tibie and tarsi dark red-brown; head fully four-sevenths as wide as the prothorax, with well-developed and rather prominent eyes and deep oblique strioles; antenne long, somewhat longer than the head and prothorax, black, the first three joints and base of the fourth pale testaceous; medial joints between two and three times as long as wide; prothorax only two-fifths wider than long, the subparallel sides distinctly and evenly arcuate, a little more converging apically, wider near the middle than at base, the angles right and sharp, the puncture not distinct; apex only feebly sinuate, with blunt angles; surface finely, feebly punctulate latero-basally, the stria strong, biabbreviated; basal fovez distinct, broadly and shallowly impressed, the inner with a short incised median line, distant from base; elytra not quite one-half longer than wide, rather obtusely rounded at apex, just visibly wider than the prothorax, the parallel sides broadly and feebly arcuate; strie fine, rather impressed, not punctate though minutely and feebly irregular, the scutellar proceeding from a distinct discal puncture; intervals broadly, feebly convex; anterior male tarsi black, distinctly dilated, the third joint oval, longer than wide. Length (co) 6.4 mm.; width 2.6 mm. New York (Ogdensburg). One specimen. May be placed near angustata, but with narrower prothorax, of very different shape, being widest near the middle. The middle tibiz in the male have a few minute inner tubercles toward tip, and the posterior are densely pubescent within, except basally, indicating that the genus is much more closely allied to Amara than to Celia. Triena irregularis n. sp.—Form and size somewhat as in the preceding, convex, shining, metallic-greenish, the elytra more bronzed; under surface and legs as in the preceding; head fully four-sevenths as wide as the prothorax, somewhat larger than in the preceding, with the eyes even larger but less convex and but slightly prominent; antennae somewhat longer than the head and prothorax, similar in coloration, but with the joints not quite so long, about twice as long as wide; prothorax broader but of similar outline and sculpture, nearly one-half wider than long, the apex however much broader, feebly sinuate, with very blunt angles; elytra scarcely three-sevenths longer than wide, obtuse at apex, slightly wider than the prothorax, with parallel.and evidently arcuate sides; striz im- pressed, minutely punctulate or unevenly broken, the scutellar similar; intervals distinctly convex; anterior male tarsi strongly dilated, the joints moderately decreasing, the third somewhat wider than long. Length (o7) 6.25 mm.; width 2.8mm. Washington State. One specimen. i ; Closely allied only to the preceding but a little broader, with the antenne slightly less elongate and the eyes much less convex, AppDITIONS TO NoRTH AMERICAN COLEOPTERA 67 the elytral striae more broken and the structure of the anterior male tarsi different, as seen especially in the third joint. Triena parallela n. sp.—Body smaller and much narrower, parallel and nearly straight at the sides, moderately convex, polished, greenish-metallic, the elytra obscurely bronzed; under surface black, the entire legs and epipleura dark rufous; head moderate, a little more than half as wide as the prothorax, the eyes notably prominent, the strioles long and rather broadly impressed; antenne longer than the head and prothorax, colored nearly as in the two preceding, the medial joints between two and three times as long as wide; prothorax three- sevenths wider than long, just visibly wider near the middle than at base, the sides very feebly arcuate, distinctly converging toward apex; basal angles feebly prominent, not blunt, the included puncture close-set, minute and feeble; apex very moderately sinuate, the angles scarcely at all blunt; surface smooth, finely, sparsely punctate latero-basally; median stria strong, greatly biabbreviated; basal impressions deep and distinct, the inner broadly impressed, narrower and feebly incised anteriorly; elytra parallel, with nearly straight sides and obtusely rounded apex, about as wide as the prothorax and nearly one-half longer than wide; striz deep, almost even, or at least not so irregular as in the two preceding, the scutellar proceeding from the usual puncture; intervals almost but not quite flat; anterior male tarsi not darker in color, distinctly dilated, the third joint tri- angular, with arcuate sides, as wide as long. Length (7) 6.0 mm.; width 2.3 mm. New York (Lake Champlain). This is by far the narrowest and most rectilinearly parallel species hitherto discovered, and is not closely allied to any other. It may follow the two preceding in the lists. Patrbbus De}. The following species is allied to fritus Csy., but is very much longer and with relatively larger head and prothorax: Patrobus canadensis n. sp.—Less ventricose than either minuens or tritus, highly polished and deep black, the under surface piceous, the legs bright rufous; head elongate, about two-thirds as wide as the prothorax, with well-developed and very prominent eyes and large deep anterior impressions; antenne blackish, slightly paler at base, a little more than half as long as the body, the third joint fully two-fifths longer than the fourth, the medial joints between two and three times as long as wide; prothorax large, three-sevenths wider than long, widest near apical third, the sides subevenly rounded, slightly oblique and less so basally, feebly sinuate before the basal angles, which are sharp and right; anterior trans- verse impression moderate, smooth and impunctate, the posterior vestigial; median line fine, rapidly coarse in basal third; latero-basal impressions large and very deep, rather loosely, not very coarsely punctate, limited outwardly by a moderate and rather short carina; base feebly sinuate medially, slightly oblique laterally, somewhat wider than the feebly sinuate apex, which has broadly rounded angles; elytra two-thirds longer than wide, only about a fourth wider than the prothorax, with parallel, arcuate sides; striae rather coarse, impressed, closely and rather strongly punctate, the fovee adjoining the third near basal and apical fourth and just behind the middle; scutellar stria free, punctured; intervals distinctly convex. Length (oc @) 9.5-10.8 mm.; width 3.35-3.8 mm. Canada (Edmonton, Alberta),—Carr. 68 . MEMOIRS ON THE COLEOPTERA The first anterior tarsal joint of the male is rather strongly dilated, the second less so and the third and fourth small and undilated. Holciophorus Lec. In this genus the form which I described under the name cephalus must be regarded as a synonym of pollens; other published names of my previous revision, such as ater Dej., and vancouveri, domitor and pollens Csy., are however evidently valid species and not subspecies, for they differ strongly among themselves in form, sculpture and other characters. Hypherpes Chd. There is a group of small species in this genus, distinguished principally by the unusually small head, such as jejunus, metlakatle, elumbis and restrictus Csy., as well as castaneus Dej. and scutellaris Lec. The two following also belong to this group: Hypherpes terracensis n. sp.—Oblong, subparallel, only very moderately convex, shining, deep black, the anterior legs rufescent distaily, especially in the male; head scarcely four-sevenths as wide as the prothorax, elongate, triangular, with rather long neck and moderate, somewhat prominent eyes; parallel apical channels coarse; antenne longer than the head and prothorax, obscure testaceous, moderately compressed, the third joint with gradual apical swelling; prothorax very nearly as long as wide, the sides broadly arcuate, gradually slightly con- verging behind and barely visibly sinuate, the hind angles a little more than right, the long seta arising from a dilated puncture; apex evenly and distinctly sinuate, with rounded angles and only a little wider than the base, which is finely, feebly margined, sinuate between the longitudinal basal impressions, which extend through basal third, the outer basal impressions short and feeble; trans- verse impressions subobsolete, the median line fine but sharply impressed, sub- entire; elytra only two-fifths longer than wide, nearly a third wider than the prothorax, very obtuse at apex, parallel, with broadly arcuate sides; striae deeply impressed and with convex intervals, especially toward the sides; scutellar stria extremely short, having the form of an elongate puncture; anterior male tarsi distinctly dilated, the other tarsi slender. Length (co) 10.5 mm.; width 4.0 mm. British Columbia (Terrace),—Mrs. W. W. Hippisley. Related to metlakatle but larger in size, with more elongate head and longer antenne, also with less arcuate thoracic sides and with deep black, broader, not violaceous and very differently striate elytra. Hypherpes stoicus n. sp.—Subparallel, moderately convex, deep black, the elytra rather less polished and feebly amethystine in lustre; legs black, the anterior male tarsi barely at all less than black; head slightly over four-sevenths as wide as the prothorax, moderately elongate, the anterior impressions widely separated, oblique and obtusely impressed; eyes very moderate, scarcely at all prominent, the antenne piceous, more testaceous distally, thick, the feebly, apically inflated third joint two and one-half times as long as wide; prothorax large, about as long AppDITIONS TO NORTH AMERICAN COLEOPTERA 69 as wide, the sides very moderately arcuate, becoming slightly oblique and broadly, just visibly sinuate posteriad, the angles right and sharp; apex distinctly sinuate, equal in width to the base or barely visibly narrower, the angles rounded; trans- verse impressions subobsolete; basal impressions deep in basal fourth, the surface feebly impressed near the angles; median line strongly impressed; elytra parallel, with feebly arcuate sides, fully two-thirds longer than wide, about a fifth wider than the prothorax; striae deeply impressed and with convex intervals, especially laterad; scutellar stria short, oblique and coarsely impressed; anterior male tarsi rather strongly dilated. Length (@) 12.3 mm.; width 4.65 mm. British Columbia (Inverness). This species is related to amethystinus Mann., especially in general structure and feeble amethystine elytral lustre, but it is larger and broader and with more broadly dilated anterior tarsi in the male than the British Columbia form, which I have assumed to be amethystinus, but rather more than possibly misidentified, as the species was described from Sitka Island. Obsidianus is also related, but has deep black and much more abbreviated elytra. The type of eluwmbis is a female and its locality was unrecorded. Recently I have found a male which corresponds very well, though slightly more elongate; it is from Montana. Hypherpes provensis n. sp.—Oblong, only feebly convex, deep black, shining, the elytra distinctly alutaceous, especially in the female; legs deep black, the anterior male tarsi distinctly dilated, nearly black; head two-thirds as wide as the prothorax, slightly more (<”), moderately elongate; eyes somewhat prominent, the apical impressions decidedly deep, coarse and slightly diverging posteriorly; antenne black, barely at all paler distally, compressed, the third joint nearly two and one-half times as long as wide; prothorax a fifth wider than long, the sides rather strongly arcuate, oblique basally, becoming feebly sinuate toward the angles, which are slightly more than right and somewhat blunt; apex broadly sinuate; surface with numerous transverse rugule, the anterior impression feeble, the posterior obsolete; basal impressions rather long and narrow, feeble toward the margin, the outer impression small, feeble, the puncture at the angles rather coarse; elytra two-thirds longer than wide, a fourth wider than the prothorax, parallel, with broadly arcuate sides, obtuse apex and very minutely denticulate humeri; apical sinus subobsolete; strie sharp, shallow (9), deep (<), the intervals nearly flat and convex alternately; scutellar stria short, fine and oblique. Length (o@Q) 13.5-14.6 mm.; width 4.9-5.2 mm. Utah (Provo Cafion and Miner’s Peak),—Spalding. This species is related to placerensis but differs in its narrower outline, straight and not distinctly sinuate middle of the thoracic base, shorter antenne and other features. Hypherpes utensis n. sp.—Still narrower (2), feebly convex, piceous through- out, the elytra alutaceous, the legs blackish; head elongate, nearly three-fourths as wide as the prothorax, narrower and with rather less developed eyes than in the preceding, the impressions slightly shorter, more arcuate, the antennz similar; prothorax much narrower, nearly as long as wide, the sides much less arcuate, distinctly but more gradually sinuate basally, the apical sinus rather deeper; 70 MEMOIRS ON THE COLEOPTERA surface and impressions nearly similar, except that the basal impressions are deeper but more disconnected from the basal margin, the latter rectilinear; elytra similar in general outline but narrower, a fifth wider than the prothorax, the strie even finer and more superficial, the intervals flat; scutellar stria a briefly attenuated puncture; apical sinuses more evident. Length (2) 14.0 mm.; width 4.5mm. Utah (Provo Cafion),—Spalding. Allied only to the preceding, but differing in its much narrower form, narrower and less inflated prothorax and finer and more superficial elytral striation. Jmntectus, from Boulder, Colo., is also related to the above two species, but the prothorax is relatively smaller and the scutellar stria very different, being fine and rather long though oblique; vivax, from Yellowstone Park, is also related rather closely, but the form is decidedly narrower than in provensis, with much less inflated prothorax, and, from utensts, to which it is allied more closely than any other species, it differs in its less basally narrowed or less anteriorly inflated prothorax, with less sinuate sides, in its somewhat more prominent eyes and more elongate attenuate puncture forming the scutellar stria. Hypherpes protensiformis n. sp.—Very elongate and subparallel, rather convex, black, moderately shining, the legs piceous; head elongate, nearly two- thirds as wide as the prothorax, with not very prominent eves and coarse. not sharply defined. postero-outwardly arcuate anterior fosse; antenne fusco- testaceous, extending slightly behind the thoracic base, the third joint a third longer than the fourth, slightly inflated at apex; prothorax about as long as wide, the broadly arcuate sides gradually becoming distinctly sinuate basally, parallel at the angles, which are right and rather sharp; base just visibly narrower than the apical sinus, which is feeble, with projecting obtusely rounded angles; surface even, the median line subentire, impressed; basal impressions near outer fifth, linear but not abrupt, rather more than a fourth the total length, smooth; surface thence to the sides feebly convex, even and smooth; elytra four-fifths longer than wide, parallel, with feebly arcuate sides, a fourth or fifth wider than the prothorax; striae strong and deep, impunctate, the scutellar a simple puncture; intervals only feebly convex. Length (#@Q) 14.5-16.4 mm.; width 4.9-5.2 mm. Cali- fornia (Berkeley). Allied to californicus, but distinctly more elongate, less accurately parallel and with more pronounced sinuosity of the thoracic sides toward the hind angles; the latter species varies much in length, my large series indicating 11.4-15.8 mm.; it is confined to the middle coast regions of California. Hypherpes baldwini n. sp.—Very slender, convex, deep black and alutaceous, the moderately broad anterior male tarsi very nearly black; head but little longer than wide, somewhat more than two-thirds as wide as the prothorax; eyes moderate, the apical impressions broad and feeble; antenne long, rufo- testaceous, much longer than the head and prothorax, the third joint very gradually broader apically and almost four times as long as wide; prothorax very AppITIONs TO NORTH AMERICAN COLEOPTERA 71 nearly as long as wide, the inflated sides rather strongly arcuate, rapidly sinuate near base, straight and parallel in basal seventh, the angles sharp and right; apex distinctly sinuate, with narrowly rounded angles; base four-fifths as wide as the apex, feebly sinuate medially; transverse impressions vestigial, the median line fine and deep, biabbreviated; fine basal impression near outer fifth, long and shallow, the surface thence to the sides nearly flat; elytra nearly twice as long as wide, a fourth wider than the prothorax, elongate-suboval; strize rather fine, with suspicion of feeble punctulation laterally; intervals almost flat; scutellar stria rather long, very fine, oblique. Length (co) 12.2 mm.; width 4.3 mm. California (Baldwin Lake—8600 ft. elev.). This peculiar species is somewhat allied to pergracilis, but the anterior cephalic lines are feebler and more diffuse, the sides of the prothorax basally more rapidly sinuate and the punctuation of the elytral striae, especially toward the sides, less visible, the intervals flatter than in the female type of that species, in which the scutellar stria is represented only by a short feeble detached vestige. The head is relatively somewhat larger. Euferonia Csy. The species in this genus are rather numerous, but they require careful and discriminative study. The following seems to be undescribed : Euferonia lacustris n. sp.—Moderately broad, strongly convex, deep black and highly polished as usual; legs black, the tarsi piceo-rufous, the anterior strongly dilated in the male; head slightly elongate, two-thirds as wide as the prothorax, with well-developed and rather prominent eyes, the anterior im- pressions coarse, deeply impressed and oblique; antenne blackish, at least basally, the third joint inflated apically, two and one-half times as long as wide; prothorax large, a fifth wider than long, the sides subparallel and evenly, moder- ately arcuate from apex to base and well reflexed, the equal gutter feebly, irreg- ularly punctulate; basal angles very broadly rounded; apex feebly sinuate, with less broadly rounded angles; transverse impressions broad and shallow, evident medially, the median line subentire; basal impressions deep and cav- ernous, rounded, sparsely punctate, somewhat uneven in outline internally; elytra three-fifths longer than wide, a fifth or sixth wider than the prothorax, parallel, with broadly arcuate sides and not very obtuse apex, the sinuses oblique but only just visibly incurvate; striz very coarse and deeply impressed, smooth, the intervals strongly convex, less so on the flanks; scutellar stria long, coarse and free. Length (o) 15.5 mm.; width 5.0 mm. Northern Illinois (near Chicago),—A. B. Wolcott. Allied to erebeus, from Lake Superior, but, as represented by the -male, larger, much broader, with more elongate head and similar broadly rounded thoracic basal angles, but broader and more punctate basal cavities and some other less evident structural differences. 72 MEMOIRS ON THE COLEOPTERA Euferonia strigosula n. sp.—Unusually narrow, moderately convex, deep black and shining; legs black, the anterior and middle tarsi rufous; head elongate, two-thirds as wide as the prothorax, with well-developed and rather prominent eyes; anterior furrows coarse, deep and parallel; antenne piceous-black, ex- tending well behind the thoracic base, the third joint swollen in about apical half; prothorax very nearly as long as wide, the arcuate sides oblique and straight in about basal half, the basal angles obtuse and rounded; base arcuate laterally, slightly narrower than the feebly sinuate apex, with broadly rounded angles; surface smooth, the transverse impressions wide and very shallow; median stria coarse, impressed; latero-basal impression large, almost rounded, but with slightly irregular outline, very deeply concave and loosely rugulose, narrowly separated from the sides; elytra fully two-thirds longer than wide, swollen and with more arcuate sides behind the middle, not quite a fourth wider than the prothorax; striz strong, smooth, very deeply impressed; intervals very convex, the third with three punctures near the second stria; anterior male tarsi strongly dilated, the second much stouter than the posterior though’not dilated. Length (@) 14.0 mm.; width 5.25 mm. Maryland (Hagerstown),—Wade. This is a distinct species, which may be placed near wmbonata, but the prothorax is larger, with more oblique and straighter sides behind the middle and without trace of the umbo within the basal impressions; it also has the diverging elytral sides from the humeri straighter. The scutellar stria is short, oblique and free. The penis is abruptly and angularly dilated at apex. Omaseus Zieg. This genus consists at present of a moderate number of species, so far as concerns the fauna of North America; the prothorax has the basal impressions double and not single, as they are in Dysidius Chd. The five following forms are sufficiently distinct as species, so far as I can discover: Omaseus equalis n. sp.—Stout, convex, deep black and polished throughout; head slightly elongate, with long and only feebly arcuate mandibles, almost three-fourths as wide as the prothorax, the eyes notably prominent and well developed; anterior furrows long, broad, deep and somewhat irregular; antenne thick, piceous-black, the third joint dilated apically and barely over twice as long as wide; prothorax fully a third wider than long, the sides rounded, a little more converging basally, becoming moderately sinuate very near the basal angles, which are slightly more than right and somewhat blunt, their setigerous puncture elongate; anterior impression feeble, the strong median line continuing thence to the base; two basal impressions at each side coalescing, forming a large, deep and densely punctate pit; elytra scarcely four-sevenths longer than wide, nearly a third wider than the prothorax, parallel, with arcuate sides and broadly but gradually rounded apex, the sinuses short ‘and very feeble; strize coarse and deeply impressed, less so and feebly punctured on the flanks; intervals distinctly though moderately convex; scutellar stria rather long, coarse, deep and free; three strial fovee rather strong. Length (9) 14.0 mm.; width 5.0 mm. New Jersey. ADDITIONS TO NORTH AMERICAN COLEOPTERA 73 This species is allied rather closely to corvinus Dej., but is much broader than the female of that species, which differs only slightly from the male, but in @qualis the eyes are much larger, still more prominent and decidedly different and the elytra are much shorter. In this genus the reflexed thoracic sides are much narrower than in Euferonia. Omaseus brevibasis n. sp.—Small in size, convex, deep black and polished, the legs black, ferruginous distally; head small, slightly elongate, three-fifths as wide as the prothorax and with notably prominent eyes, the anterior furrows narrow and arcuate; antenne slender, piceous; prothorax scarcely a fifth wider than long, the rounded sides becoming feebly sinuate but only very near the right and sharp basal angles; base truncate, four-fifths as wide as the feebly sinuate apex; transverse impressions very feeble, the anterior medial only; median line rather deep, not quite entire, narrow; basal impressions distinct, the inner with strong sparse punctures; finely reflexed margins with a fine setig- erous puncture at apical third and another, as usual, at the basal angles; elytra three-fifths longer than wide, a fourth or fifth wider than the prothorax, gradually arcuately rounded behind the middle; striae coarse, deeply impressed, feebly punctate and with convex intervals, the scutellar stria rather long. Length (92) g.8 mm.; width 3.2 mm. New York (near the city). Related to caudicalis, but smaller, with much smaller head and relatively somewhat larger prothorax, the sides at the basal angles much more briefly subparallel. Omaseus tenuis n. sp.—Narrow and parallel, convex, deep black and polished, the legs rufous, with blackish femora; head with notably prominent eyes, nearly three-fourths as wide as the prothorax, the anterior impressions narrow, deep and arcuate; antenne piceo-rufous, longer than the head and moderately com- pressed; prothorax very nearly as long as wide, the broadly arcuate sides very briefly and feebly sinuate at the sharp basal angles; base narrower than the apex, which is only just visibly sinuate; impressions obsolescent, the median line almost entire, fine, coarse basally; basal impressions long, narrow, well separated and deep, the inner with numerous moderate punctures; elytra nearly two-thirds longer than wide, parallel and almost straight at the sides, rounding in apical third or fourth, more than a fourth wider than the prothorax; strie nearly as in the preceding but less distinctly punctate, the fovee as usual, two on the second and one on the third stria. Length (@) 8.5 mm.; width 2.7 mm. New Jersey. This species may be placed near /uctuosus Dej., but it is much narrower and more parallel. Omaseus confluens n. sp.—Much broader in form and more parallel than in luctuosus, deep black and highly polished, the legs black, with rufo-piceous tarsi; head two-thirds as wide as the prothorax, with very prominent eyes, the anterior strie rather slender, arcuate; antennz much longer than the head and prothorax, piceous, gradually ferruginous distally; prothorax large, convex, only a seventh wider than long, the sides subevenly arcuate and nearly parallel throughout, the basal angles minute and sharp; base but little narrower than the very feebly sinuate apex, the latter with rather broadly rounded angles; transverse im- pressions obsolete, the stria as in the preceding; basal impressions different, 74 MEMOIRS ON THE COLEOPTERA forming a rounded, strongly and closely punctured concavity, deeply incised at its anterior margin; elytra oblong-oval, three-fifths longer than wide, only about a fifth wider than the prothorax, the feebly arcuate sides gradually rounding be- hind about the middle; strie throughout nearly as in /uctuosus; anterior male tarsi very pale testaceous, distinctly dilated. Length (@) 9.2 mm.; width 3.2 mm. Rhode Island (Boston Neck). This distinct species differs from /Juctuosus in its much more parallel outline, larger prothorax, with the sides not distinctly sinuate even at base, also in its broadly confluent basal impressions. A female, unlabeled in the Levette collection, also belongs to this species, although the basal thoracic impressions are not quite so broadly confluent and having sparser and coarser punctures. Omaseus testaceus n. sp.—Feebly ventricose, convex, pale testaceous, highly polished and with dense integuments; head fully two-thirds as wide as the pro- thorax, with very prominent eves, the anterior strioles long, slender and arcuate; antenne rather long, slender and but feebly compressed, the third joint barely over twice as long as wide; prothorax between a fourth and fifth wider than long, the sides subevenly arcuate, becoming gradually very shallowly sinuate toward the right and sharp basal angles; base evidently but not greatly narrower than the subtruncate apex; impressions obsolete, the median line as in the pre- ceding species; basal impressions rather long and narrow, sharply impressed, arcuately uniting at base, the inner with very few punctures; elytra oblong-oval, scarcely three-fifths longer than wide, almost a third wider than the prothorax, the subparallel arcuate sides gradually rounding behind the middle; striz and intervals nearly as in /uctuosus; tarsi slender. Length (2) 9.0 mm.; width 3.2 mm. Rhode Island (Boston Neck). This is a peculiar species in other ways than the pale coloration, even if the latter should prove to be due in any way to immaturity in the single type. The thoracic apex is margined by a fine incised line, interrupted at the middle and wholly unobservable in any other species of this group, and the convex polished surface has at outer fifth, from the middle to apical fourth, a very feeble line of well-spaced extremely shallow punctures. Dysidius Chd. The few species of this genus are of small or moderate size, black and shining, and they are distinguishable from Omaseus by ’ the single elongate basal thoracic impression at each side, instead of the two always seen in that genus, the latter differing from Euferonia, which also has two more or less coalescent impressions, by the smaller size and more evident basal thoracic angles. The following I believe to be hitherto undescribed: Dysidius egens n. sp.—Nearly similar to mutus but much smaller; coloration and lustre similar; head narrower, though not when compared with the prothorax, AppITIONs TO NORTH AMERICAN COLEOPTERA 75 the eyes even less prominent; antennz shorter and with the outer joints very much more abbreviated, the third joint shorter and apica!ly less inflated; pro- thorax smaller and shorter, a sixth wider than long, the surface and impressions nearly similar, the inner slope of the deep basal impressions strongly and densely punctate; hind angles similarly obtuse, though slightly prominent; elytra similar but narrower, the three strial fovee smaller. Length (2) 9.5 mm.; width 3.25 mm. New Jersey. Differs from mutus in its much smaller size, narrower form, shorter antenna, especially in the distal joints, less prominent eyes, shorter prothorax, shorter thoracic basal impressions and some other characters. Micromaseus Csy. So far as known, the small species of this genus, with patruelis Dej., as the type, are few in number and are most abundant in the Atlantic regions of the continent, but the following Pacific species is notably different: Micromaseus longicollis n. sp.—Subparallel, rather convex, black, the epipleura and legs piceous; head longer than wide, nearly three-fourths as wide as the prothorax, the eyes well developed and rather prominent; antennz piceo-rufous, as long as the head and prothorax, notably thick, compressed, the third joint more obconic, just visibly longer than the fourth; prothorax slightly elongate, the sides broadly and moderately arcuate, becoming shallowly sinuate toward the basal angles, which are sharp and right; base broadly and feebly sinuate, a little narrower than the very feebly sinuate apex, which has rather blunt angles; surface smooth, the transverse impressions obvious but shallow medially, the stria subentire and deep; sublateral impressions at base linear, rather deep and a fourth the total length; scutellum minute, short and obtuse; elytra oblong-oval, nearly three-fifths longer than wide and between a fourth and fifth wider than the prothorax; striz# impressed, moderately deep, smooth, the scutellar wanting and represented by a basal fovea; legs moderate, the anterior male tarsi but slightly dilated. Length (@) 6.8 mm.; width 2.25 mm. Washington State (Seattle),—C. V. Piper. One specimen. This distinct species is distinguishable at once from patruelis by its larger size, more elongate prothorax, thicker antenne and absence of the scutellar stria. Pecilus Bon. The forms clustering about /ucublandus Say, are numerous but as yet unstudied; this is a very common species, represented by a large series from eastern temperate North America and the lake regions. The legs are normally black or piceous black, but in certain examples, which cannot readily be separated otherwise, they are pale testaceous; in a few cases, however, the testaceous legs seem to form a specific character. There are three forms allied to lucublandus, which may be regarded as subspecific; they are the following: 76 MEMOIRS ON THE COLEOPTERA Pecilus lucublandus ssp. manhattanis Csy.—Agrees with Jucublandus though larger and broader, but distinguished essentially by having five or six strong punctures on the third strial interval, instead of the usual three or four. The legs are black throughout, the tarsi not paler. Length (@) 13.4 mm.; width 4.8mm. Long Island. One specimen. 5 It is to be regretted that only one specimen has been found, for should duplicates occur, there could be no doubt of specific dis- tinction, in view of the large size and broader outline. Peecilus lucublandus ssp. louisinus nov.—Large, still broader than mankattanis, with the general structure of /ucublandus, but having very pale testaceous legs throughout; third strial interval with four punctures, the first two and last ad- joining the third stria, the third near the second. Length (co) 13.0 mm.; width 4.9mm. Missouri (St. Louis). One specimen. This is even broader than manhattanis and quite unlike the mass of representatives of lucublandus. Peecilus lucublandus ssp. acomanus nov.—Much smaller and narrower than either of the preceding, more parallel, the elytra less inflated, black and non- metallic throughout, rather shining, the elytra duller in the female; legs pale testaceous, the tarsi slightly darker; parts proportioned nearly as in /ucublandus. Length (@ @) 9.5-10.5 mm.; width 3.7-4.25 mm. New Mexico (Jemez Springs), —Woodgate.: Two specimens. It is highly probable that this will prove to be specifically distinct from lucublandus. The male is much larger than the female, and also somewhat stouter, in the pair at hand. The two following are to all appearance specifically distinct from lucublandus: Peecilus elucens n. sp.—Rather narrowly oblong-suboval, polished, black, with more or less feeble greenish lustre; parts nearly as in /ucublandus, except that the antenne are more slender, similarly dark, with the first three joints pale testaceous; prothorax narrower, the sides less inflated, the apex narrower, relatively more deeply sinuate and with sharper angles; elytra similar, only a little wider than the prothorax, subsimilarly striate but with flatter intervals, the third with three to five punctures; legs piceo-rufous, with black femora. Length (@) 9.5-11.0 mm.; width 3.6-4.2 mm. Canada (Edmonton, Alberta), —Carr. Three specimens. Distinguishable from Jucublandus by the smaller size, rather narrower form, narrower prothorax and some other characters. Peecilus planifer n. sp—Form and general structure of the parts nearly as in lucublandus, but somewhat narrower; coloration and metallic lustre similar; legs piceous, polished, the elytra (QQ) alutaceous; head suboval, the eyes even less prominent than in the latter; prothorax similar but with sharper apical angles; elytra also nearly similar, but relatively wider than the prothorax; strie finer and feebly subpunctate, exarate at apex; intervals flat; discal punctures finer, about four in number. Length (9) 9.4-10.5 mm.; width 3.6-4.25 mm. British Columbia (Agassiz). Three specimens. ADDITIONS TO NORTH AMERICAN COLEOPTERA 77 This form is distinct from lucublandus in the finer striz, with more perfectly flat intervals even than in the female of the latter species, also in the narrower prothorax. Bothriopterus Chd. The moderate number of species at present composing this genus are closely allied among themselves, but the following is an addition, which it seems worth while to propose: Bothriopterus angusticollis n. sp —Oblong, rather convex, deep polished black throughout, the somewhat strongly dilated anterior male tarsi piceous-black; head about as wide as long, two-thirds as wide as the prothorax, with well-devel- oped prominent eyes, the strongly compressed antenne moderate, piceous; pro- thorax scarcely a fifth wider than long, the arcuate reflexed sides somewhat oblique and nearly straight posteriad; base slightly narrower than the distinctly sinuate apex; basal angles slightly obtuse but distinct; transverse impressions evident; basal impressions acutely formed and deep, finely punctate externally; elytra three-sevenths longer than wide, but little over a fourth wider than the prothorax, slightly widest behind the middle, the sides arcuate; apex obtuse, with distinct sinuses; strie rather fine, closely and feebly punctulate, the scutellar rather long; intervals not quite flat, the five foveiform punctures coarse and deep. Length {@) 10.0 mm.; width 3.8 mm. Utah (Provo Cafion),—Spalding. May be compared with Jatescans Csy., but differs in the rather smaller head and eyes and somewhat narrower prothorax, less punctured latero-basal part of the pronotum, shorter scutellar stria and generally smaller size of the body. Cyclotrachelus Chd. The species of this genus appear to be rather numerous, but they are individually rare as a rule, so that I am unable to affirm that all of those now included under the name are truly Cyclotrachelus. The following is an additional species: Cyclotrachelus fallaciosus n. sp.—Barely at all ventricose, convex and deep black throughout, moderately shining; head four-sevenths as wide as the pro- thorax, with rather prominent eyes and narrow, parallel and slightly arcuate anterior furrows; antenne rather slender, extending well behind the prothorax, black, gradually becoming ferruginous distally, the third joint subevenly obconical and fully a fifth longer than the fourth; prothorax almost as long as wide, sub- circular, the sides feebly sinuate near the obtuse basal angles; base barely over two-thirds as wide as the feebly sinuate apex, which has broadly rounded angles; transverse impressions obsolete, the stria deeply impressed, biabbreviated; surface smooth, the outer subbasal impressions very deep, moderate in size, oval, smooth and much nearer the sides than the middle; margins finely reflexed; elytra oval, more attenuated posteriorly than basally, three-fifths longer than wide, a fourth or fifth wider than the prothorax; striae strong, broadly impressed and coarsely, loosely, seriately punctate, becoming gradually much finer, feeble and impunctate posteriad; intervals moderately convex, flatter behind; discal T. L. Casey, Mem. Col. XI, Mar. 1924.—6 78 MEMOIRS ON THE COLEOPTERA puncture at the second stria near three-fifths minute and feeble. Length (co) 11.5 mm.; width 4.2 mm. Southern Florida (Dunedin),—Batchley. This species differs from roticollis Csy., from the same regions, in its more parallel form, the elytra being less inflated and with much more coarsely and distantly punctured striz, obsolescent behind. The anterior male tarsi alone are dark rufo-piceous in color. Monoferonia Csy. The following species is smaller and much narrower than osculans Csy., the type of the genus. In some respects MJonoferonia re- sembles Gastrosticta, but it differs very much in the sculpture of the abdomen, as well as in other ways. Monoferonia idahoanus n. sp.—Narrowly ventricose, strongly convex, deep black and shining, the legs black, the dilated anterior male tarsi alone rufo- piceous; head elongate, the eyes moderately prominent, the anterior furrows moderate, parallel; antenne extending scarcely beyond the thoracic base, the moderate third joint slightly inflated at apex; prothorax as long as wide, the sides broadly arcuate, gradually feebly converging behind to the rounded obtuse angles, which are margined internally by a narrow curving groove; base un- margined, three-fourths as wide as the apex, which is feebiy sinuate, with obtusely rounded projecting angles; side margins very finely reflexed throughout; trans- verse impressions narrow and evident, the stria fine and biabbreviated; subbasal impressions smooth, narrow, longitudinal, a seventh the total length and at nearly their own length from the base, nearer the outer side than the middle; elytra very evenly oval, widest at the middle, four-sevenths longer than wide and scarcely a fifth wider than the prothorax; stria smooth, rather distinct, impressed and equal throughout the length, the scutellar very short, oblique; intervals moderately convex; discal puncture apparently wanting; abdomen piceo-rufous, smooth and only with the double median line of punctures. Length (o%) 9.4 mm.; width 3.2 mm. Idaho (Moscow Mt.). One example. Differs from osculans in its smaller size and narrower form, also in its more slender antenne, very much smaller subbasal thoracic im- pressions and in the more abbreviated and less deeply striate elytra; ’ the antenne are dark ferruginous, gradually becoming darker piceous basally. I have recently received a large series of osculans, taken by Prof. C. V. Piper at Priest Lake, Idaho. Evarthrinus Csy. The following species is related to sodalis Lec., which is the same as the fatuus of that author, the former name applying to the male, the latter to the female: Evarthrinus inflatipennis n. sp—Convex, rather ventricose, castaneous, the under surface and legs rufous, convex, rather shining (@), the elytra alutaceous AppiTIONs TO NortTH AMERICAN COLEOPTERA 79 but not opaque; head three-fifths as wide as the prothorax, rather elongate, with well-developed moderately prominent eyes and very deep anterior furrows; antenne moderate, testaceous; prothorax relatively small, between a third and fourth wider than long, the sides strongly arcuate, gradually strongly converging posteriad to the rather abrupt sinus and parallel for about a ninth or tenth the length before the angles, which are slightly obtuse and blunt; base fully three- fourths as wide as the deeply and broadly sinuate apex; impressions obsolete; stria deep at basal third, slightly biabbreviated; latero-basal impressions narrow, rather short and approximate, nearly smooth; elytra almost three-fifths longer than wide, nearly three-sevenths wider than the prothorax, parallel, with arcuate sides and gradually rounded apex; stria moderate, impressed and with moderate and well-separated punctures, the scutellar very short, coarse and oblique; inter- vals not quite flat; single puncture of the second stria rather small, just behind the middle. Length (9) 13.0 mm.; width 5.2 mm. Northern Illinois (near Chicago),—A. B. Wolcott. Differs from the female of either sodalis or impolitus in its rela- tively very much smaller prothorax; the unusually small latero- basal impressions resemble those of tm politus, but are smoother and still shorter, but they are very different from the deeply cavernous united impressions of sodalis. Loxandrus Lec. It is reasonably certain that my representative of Feronia recta Say, is a true identification of that species, for it agrees with the original description in its broad prothorax, with rapidly rounded basal angles and other characters, though differing somewhat in its smaller size, being only about 12 mm. long. Rectus is a large species, when compared with the Feronia (Argutor) velox of Dejean —3 |., or 6 mm. in length, according to Dejean, and the two species cannot therefore be closely allied, although the latter is made a synonym of rectus by Mr. Leng. It would seem to me that velox Dej., must be very close to agilis, if not a synonym of that species. There is reason to believe that Jucitdulus Dej.,is the same species as that which I identified as Jucens Chd.; lucidulus should therefore be recorded as a valid species, with Jucens as a synonym, according to present lights. MJandibularis is an entirely different species from rectus, though of nearly similar size; it has a relatively much narrower prothorax, with less arcuate sides and differs very much also in the coloration of the mandibles. The species which I have identified as Jaticollis Chd., is shorter and relatively broader than rectus and it is valid. The species described by Blatchley under the name brunneus is seen, by a cotype given me by the author, to be exactly the same as mundus Csy. It should be said also that scitus Csy., is taken in some numbers by Léding at Mobile, agreeing 80 Memoirs ON THE COLEOPTERA throughout with the Florida types; the antenne are obviously thicker than in contumax. Loxandrus is one of those genera in which it is almost impossible to identify, in any certain way, many species by the published descriptions, and it is most regrettable that the types of Chaudoir cannot be compared directly with our own. The two following are distinctly characterized species, hitherto undescribed : Loxandrus cincinnati n. sp.—Suboval and elongate, polished, black, the legs obscure testaceous, the femora black; head smooth, slightly elongate, rather more than half as wide as the prothorax, the antenne slender, testaceous, evidently more than half as long as the body (co); prothorax barely a fifth wider than long, the parallel sides very evenly arcuate throughout, the basal angles evidently more than right but sharp and not at all rounded; surface with the longitudinal impressions short, not attaining the base, with very few attendant small punctures, almost extending transversely throughout between them, the reflexed lateral margins fine and translucently testaceous; elytra two-thirds (co), or three-fifths (@ ), longer than wide, with parallel, broadly arcuate sides and very faint subapical sinus, at the middle distinctly wider than the prothorax; strie strong and deeply impressed, with fine and close-set punctures, subexarate apically; anterior femora much swollen in the male. Length 10.0-10.5 mm.; width 3.7 mm. Ohio (Cincinnati). A male and female of this species were very kindly communicated by Mr. Dury. It belongs near inquietus Csy., but is larger in size and broader in outline, with more evenly arcuate sides of the prothorax and longer antenne. Loxandrus breviusculus n. sp.—Body more abbreviated than usual, convex, polished, black, the elytra with the feeblest possible iridescence, the femora black; tibiz nearly black, the tarsi testaceous; head longer than wide, well developed, fully four-sevenths as wide as the prothorax; apical impressions small but evident; antenne slightly longer than the head and prothorax, moderately slender, dusky, the first three joints more testaceous; prothorax nearly a third wider than long; apex slightly narrower than the base, which is evenly and moderately arcuate, the basal angles distinctly rounded; side margins finely reflexed, not paler; basal lineate impressions extending almost to the base, with very few minute intermediate punctures; elytra slightly less than one-half longer than wide, more than a fourth wider than the prothorax, with broadly arcuate sides and feeble subapical sinus; stria moderate, rather impressed, not coarsely but strongly, closely punctate, the seventh fine and subobsolete broadly toward base; intervals perfectly flat apically. Length 8.2 mm.; width 3.3 mm. Florida (Dunedin),—Blatchley. The single female, when compared with the unique female type of comptus, is shorter and broader in form, the prothorax of the latter being only a fifth or sixth wider than long, with the basal impressions far from the basal margin, the seventh stria somewhat as in breviusculus and the antenne distinctly longer. Species of this genus seem to be numerous in southern Florida. AppiTions TO NORTH AMERICAN COLEOPTERA 8I Anchomenus Bon. But few additions to this large genus have become known recently, as follows: Anchomenus missourianus n. sp.—Body notably broad, with unusually flat surface of the elytra, polished and deep black throughout; head elongate-rhombic, fully two-thirds as wide as the prothorax, with only moderately prominent eyes, the apical impressions very oblique, irregular and shallow; antennz black, three-fourths as long as the elytra, rather slender, the third joint slightly longer than fourth; prothorax only a fifth or sixth wider than long; sides parallel and broadly arcuate, widely reflexed, becoming shallowly sinuate toward the rather sharp and feebly prominent angles; base wider than the distinctly sinuate apex; transverse impressions distinct medially; basal impressions large, rather deeply concave and loosely but distinctly punctate; elytra not quite one-half longer than wide, parallel, with arcuate sides, obtusely rounded apex and distinct sinuses, four-sevenths wider than the prothorax, with rather coarse, subpunctate and deeply impressed striz and notably convex intervals, the three coarse punctures evident; scutellar stria moderately long, deep and iree.

Anchomenus uteanus n. sp.—Very moderately ventricose and frail in structure, black, moderately shining, the elytra sometimes feebly wneous; under surface and legs blackish-piceous, the latter often testaceous; head but slightly elongate, with well-developed and rather prominent eyes; antenne slender, the third joint evidently shorter than the fourth and more slender; prothorax as long as wide to somewhat wider, the sides moderately arcuate, slightly oblique and nearly 82 MEMOIRS ON THE COLEOPTERA straight basally, the basal angles very obtuse between the sides and rounded sides of the base though finely sharp at apex; base subequal to the evidently sinuate apex; transverse impressions feeble, the median line fine, not quite entire; basal impressions at outer fifth, narrow but broadly and deeply impressed, the inclined sides thence outwardly feebly punctulate; elytra one-half ( Q) to three- fifths (co) longer than wide, with feebly arcuate sides and gradually obtuse apex, nearly four-fifths wider than the prothorax; striz fine, smooth, the scutellar rather long, free; intervals almost flat, the third with five or six punctures at the third or second stria; anterior male tarsi very feebly dilated. Length (@ 2) 7.5-8.0 mm.; width 2.7-3.3 mm. Utah (Callao),—Spalding. Six specimens. This species is one of the extensicollis section, but is much smaller than the latter and with shorter and blackish antenne, having only the first joint pale, also with much finer elytral striz. Anchomenus amplicollis n. sp.—Shining, black, the legs black, with rufescent trochanters, the epipleura rather pale; elytral surface depressed, with #neo- subcupreous lustre; head slightly elongate, scarcely two-thirds as wide as the prothorax, with well-developed, moderately prominent eyes, the anterior impres- sions greenish, broad and irregular; antenne very slender, blackish, nearly half as long as the body, the third joint not quite as long as the fourth; prothorax large, about a fifth wider than long, slightly widest a little beyond the middle; sides parallel, broadly arcuate, becoming barely perceptibly sinuate gradually toward the rather sharp and feebly prominent angles, which are more than right; base slightly oblique at each side, rather wider than the apex, which is distinctly sinuate, with slightly blunt angular apices; surface like the head, very feebly subeneo-metallic, the transverse impressions vestigial; median stria fine, im- pressed, apically abbreviated; latero-basal impressions large, rather deep and smooth; elytra three-sevenths longer than wide, three-sevenths wider than the prothorax, parallel, with slightly arcuate sides, rounded at apex; surface nearly flat, rapidly declivous and somewhat greenish at the sides; striz@ fine, smooth; intervals flat, the third with six punctures; scutellar stria rather long, free; anterior male tarsi very moderately dilated, not paler. Length (co) 10.0 mm., width 3.8 mm. California (Berkeley). This is a notably distinct species, differing from fexanus, near which it should be placed, in its larger size, broader and flatter form, more prominent basal thoracic angles, broader head and larger prothorax; it is altogether different from calzfornicus in its much larger size, broader form throughout, flatter elytra and more prominent basal thoracic angles. Platynus sulcipennis of Horn, of which I now have a number of specimens taken by Mr. Léding, is a perfectly normal species of Anchus, and albicrus Dej., also given me by Mr. Léding, is a typical member of the genus Tetraleucus, although the contrast in color between the last four whitish antennal joints and the seventh, is not quite so abrupt and conspicuous as in picticornis. The extremely slender legs are blackish, with peculiarly whitish tibiz, the latter gradually blackish apically. ADDITIONS TO NORTH AMERICAN COLEOPTERA 83 Agonum Bon. The species identified as Agonum seminitidum of Kirby, which I have in abundance from Lake Superior and one from Winnipeg, is not the same as seminitidum, from Lat. 54°, for, instead of being greenish-bronzed, with the elytra black-bronze, it is bright cupreous throughout above and I would therefore change its name to cupreo- lucens (nom. nov.). Agonum uintanum n. sp.—Rather narrowly parallel, convex, shining, the upper surface bright cupreous, the lower greenish-black, the legs deep black throughout; head barely longer than wide, fully two-thirds as wide as the pro- thorax, the eyes well developed but not obviously prominent; antenne not very long or slender, deep black throughout, the third joint longer than fourth; prothorax rather short, between a third and fourth wider than long, widest near apical two-fifths, but with the sides subevenly rounded, less arcuate basally, the basal angles very obtuse and rounded; transverse impressions distinct, the stria between the two deep and broadly impressed; impressions near the base at outer fourth linear, broadly impressed and deep, with some transverse rugulosity; base fully as wide as the apex, which is very shallowly sinuate; moderately reflexed margins continued around the basal angles to outer fourth, becoming rather stronger and bearing a shallow elongate puncture; elytra not quite one- half longer than wide, only a third wider than the prothorax, obtusely rounded at apex, with almost obsolete sinuses, the parallel sides very moderately arcuate; striz fine, abrupt and smooth, the scutellar very short and fine; intervals nearly flat, the third with five punctures. Length (co) 7.2 mm.; width 2.8mm. Utah (Parowan Mts., Mammoth—1oo00 ft. elev.). This species is brilliantly cupreous as in cupreolucens, but is much smaller and more abbreviated, with somewhat larger head and shorter and more transverse prothorax. The anterior male tarsi are black and rather well dilated, much shorter than in the male of cupreolucens, the second joint being not quite as long as wide; in the latter species it is much longer than wide. I have recently received a specimen of /ongulum, more elongate and less purely cupreous than cupreolucens and found at Douglas, Utah; this specimen, which matches the type of longulum very well, was taken by Spalding in Provo Canon, Utah. Agonum amens n. sp.—Oblong, convex, shining, deep black, the legs piceous; size small; head elongate, two-thirds as wide as the prothorax, with well-developed and rather prominent eyes; antenne black, extending well upon the elytra, more slender basally, the third and fourth joints equal; prothorax a third (<7) to two-fifths (9°) wider than long, the sides parallel, evenly rounded, narrowly reflexed, the gutter lost in the basal flattening, which is feebly sculptured, rather less shining and with a feeble basal impression near outer fifth; basal angles broadly rounded; apex slightly narrower than the base, deeply sinuate and with distinct and feebly blunt angles; anterior transverse impression fine and feeble but evident, the median stria rather fine, deep and subentire; elytra broad, oblong, with slightly arcuate picescent sides and rapidly rounded apex, two-fifths longer than wide, less than one-half wider than the prothorax; strie fine and 84 MEMOIRS ON THE COLEOPTERA shallow, simple, the scutellar moderate; intervals nearly flat, the third with three discal punctures; anterior male tarsi very narrowly dilated. Length (o@ 9) 6.4-6.6 mm.; width 2.4-2.65 mm. Canada (Edmonton, Alberta),—Carr. Three specimens. A distinct species, which may be placed near zmswetum, but shorter and stouter and with shorter tarsi; the hind tarsi of zmswetum are more slender, with the joints much more elongate. Agonum invalidum n. sp.—Small and notably narrow, black and shining throughout, the legs black; upper surface with the feeblest subzneous glimmer; head but slightly elongate, with large and somewhat prominent eyes, fully three- fourths as wide as the prothorax; apical impressions deep and punctiform; antenne black, slender, half as long as the body, the third joint just visibly longer than the fourth; prothorax small, barely perceptibly shorter than wide, the sides parallel, evenly arcuate; base arcuate, with obtuse but not very widely rounded angles, evidently wider than the apex, which is shallowly sinuate, with not much produced and narrowly blunt angles; surface smooth, with some transverse ruguliform lines, subobsolete transverse impressions and shallow elongate basal impressions near outer fifth, the surface thence broadly, shallowly reflexed to the sides and less shining but not punctate; elytra long, parallel, with slightly arcuate sides and rapidly circularly rounded apex, three-fourths longer than wide and four-sevenths wider than the prothorax; strie very fine, not impressed; intervals flat, the third with five small punctures near the third and second stri#; scutellar stria fine, not free, proceeding from a basal puncture; anterior male tarsi very narrowly dilated, black. Length (o) 6.0 mm.; width 2.0mm. Canada (Edmonton, Alberta),—Carr. One specimen. This species, though notably small and frail, may be placed in the placidum section, near rhodeanum, but it is smaller and very much more slender. Agonum rhodeanum n. sp.—Form somewhat as in placidum Say, but much smaller, more pallid and with even thinner integument, shining, castaneous, the head black; under surface blackish-piceous, the legs dark testaceous; head barely longer than wide, nearly three-fourths as wide as the prothorax, with large and rather prominent eyes; antenne slender, blackish, with testaceous first joint, the third barely visibly longer than the fourth; prothorax a fourth wider than long, the sides parallel and subevenly arcuate; basal angles very obtuse, narrowly rounded at tip; base arcuate, somewhat wider than the feebly sinuate apex; sides moderately reflexed, gradually broadly concavo-explanate basally and finely punctato-rugulose; transverse impressions obsolete, the stria fine, entire; elytra scarcely one-half longer than wide, parallel, with arcuate sides and broadly rounded apex, three-fourths wider than the prothorax; striz very fine, the scutellar moderate, free; intervals flat, minutely, sparsely and obsoletely punctulate, the five small punctures of the third in great part near the third stria. Length (@) 6.8 mm.; width 2.7 mm. Rhode Island. This form was previously mentioned by me as constituting one of the extremes of placidum in point of size, but subsequent study convinces me that it really represents a distinct species, the smallest of a large series of the true placidum being 7.2 by 2.8 mm. in di- ADDITIONS TO NORTH AMERICAN COLEOPTERA 85 x mensions. The still more narrowly dilated anterior male tarsi are decidedly longer than in placidum. Agonum terracense n. sp.—Oblong, moderately convex, rather abbreviated, polished and deep black, the elytra feebly greenish-metallic; under surface and legs throughout deep black; head two-thirds as wide as the prothorax, short, with large and somewhat prominent eyes and widely separated parallel apical grooves; antenne wholly deep black, slender, the third joint equal in length to the fourth; prothorax transverse, three-sevenths wider than long, the parallel sides evenly and distinctly arcuate; basal angles broadly obtuse, the apices distinctly rounded, with a small puncture in the thickened reflexed edge; base much wider than the deeply sinuate apex, which has very distinct angles; broadly arcuate transverse impressions fine and fecble, the stria fine, biabbreviated; surface latero-basally concavo-explanate, nearly smooth; impression at outer fourth narrow and linear; elytra oblong, with feebly arcuate sides, broadly rounded apex and very feeble sinuses, two-thirds wider than the prothorax; strie moderate, deep, stronger suturally, where the intervals are broadly convex, flat externally, the third with three punctures, at the third stria, central and at the second, in succession; scutellar stria free; anterior male tarsi deep black, very moderately dilated, rather short. Length (co) 7.5 mm.; width 3.0 mm. British Columbia (Terrace),—Mrs. W. W. Hippisley. This notably distinct species may be placed near @thiops, but is shorter and relatively broader, with larger and more prominent eyes, less elongate antennze and with many other differences, including coloration, @thiops being deep shining black throughout. From Edmonton, Alberta, I have three specimens that are evidently hyslopi, although the latter was described from Washing- ton State. Europhilus Chd. In my previous work on this genus two subspecific forms are attached to /utulentus Lec., but it is found on further study that elegantulus Csy., is purely a synonym of that species, while adustus must be elevated to specific rank, as it is a much narrower form, the prothorax especially being notably narrower and often sub- elongate; atriceps has a much shorter hind body, with relatively stronger striation. The three following species are recent dis- coveries to be added: Europhilus carri n. sp.—Elongate, rather convex, feebly ventricose, black, with piceous elytra; under surface black, the legs piceous to testaceous; head longer than wide, three-fifths as wide as the prothorax, the eyes well developed but scarcely at all prominent; apical furrows coarse, deep and parallel; antenne bicolored, slender, the third joint longer than fourth, joints one to four black, thence testaceous; prothorax about as long as wide, widest slightly beyond the middle, but with broadly and subevenly rounded sides and broadly rounded basal angles; sides narrowly reflexed, a little more so basally; base a little wider than the very feebly sinuate apex, having rather broadly rounded angles; trans- verse impressions vestigial; latero-basal impressions wide, deep, moderately 86 MEMOIRS ON THE COLEOPTERA elongate, almost smooth; elytra less than one-half longer than wide, oblong-oval, three-fifths wider than the prothorax, with rather fine smooth strie and flat intervals, feebly convex at the suture; anterior male tarsi narrowly dilated. Length (co 9) 6.3-6.4 mm.; width 2.35-2.4 mm. Canada (Edmonton),—F. S. Carr. The legs in the female type are virtually black, with piceo- testaceous coxe and trochanters, but in the male they are pale testaceous throughout; there are no other differences at all obvious. This species is very much smaller, shorter and relatively broader than picetpennis Kirby, also broader and heavier than serenus and with broader head. Europhilus sordens Kirby—Smaller and narrower, moderately convex, shining, black, with feeble greenish lustre, the elytra obscure testaceous; under surface black, the epipleura and legs throughout pale brownish-yellow; head rhombic, three-fourths as wide as the prothorax, with well-developed and moderately prominent eyes; antenne black, extremely slender; basal joint, and also the hypo- mera, piceo-testaceous; prothorax rather small, very little wider than long, widest slightly beyond the middle, the sides subevenly arcuate, a little more converging basally, the basal angles very obtuse, with narrowly rounded apices; base dis- tinctly narrower than the shallowly sinuate apex, having rather distinct though blunt angles; transverse impressions subobsolete, the median line unusually coarse and deeply impressed, the latero-basal impressions large, concave and moderately elongate; elytra not quite one-half longer than wide, oblong-oval, with gradually broadly rounded apex, four-fifths wider than the prothorax; strie fine, the inter- vals nearly flat, the about five punctures of the third fine. Length (2) 5.4 mm.; width 2.0 mm. Massachusetts (Framingham),—C. A. Frost. This species is not closely allied to any other, one of the smallest known to me thus far, although the next is also about as small. The antenne are notably slender, even for the present genus. As the locality is somewhat remote from that of the original type— lat. 54° in western Canada—I cannot be completely sure: of the identification, but my representative satisfies all the characters of Kirby’s description, though perhaps a little smaller, the length given by the latter author being 3 lines, or 6 mm. Europhilus frosti n. sp.—Small, moderately ventricose and evidently convex, shining, black, the elytra piceous; under surface black, the epipleura yellow, the legs slightly darker rufous, with blackish tarsi; head narrow, elongate, two- thirds as wide as the prothorax, with broad shallow oblique apical impressions, each inclosing a puncture near the apical margin; eyes moderate, scarcely at all prominent; antenne slender, black, the first joint barely at all paler; prothorax a fifth wider than long, the parallel sides evenly and moderately arcuate, more reflexed at the obtuse rounded basal angles; base oblique laterally, about as wide as the moderately sinuate apex, the latter having narrowly rounded angles; surface as in sordens; elytra scarcely one-half longer than wide, with broadly arcuate sides, obtuse apex and very shallow sinuses, three-fourths wider than the prothorax; striz fine, feebly impressed, gradually more deeply toward the suture, the scutellar moderate, free; anterior male tarsi blackish, very feebly ApDITIONS TO NORTH AMERICAN COLEOPTERA 87 dilated. Length (@) 5.3 mm.; width 2.18 mm. Maine (Eastbrook),—J. H. Emerton. Resembles sordens somewhat in its small size, but differs in its narrower head, with still less prominent eyes, slightly broader pro- thorax, with less basally oblique sides, broader and less convex elytra, with more deeply impressed striz, and in the slightly less slender antenne, with nearly black basal joint. The third strial interval bears the usual four or five punctures of the genus. This species is named in honor of Mr. C. A. Frost. At Eastbrook, Mr. Emerton also took a considerable series of the Adirondack species, which I identified as retractus Lec. Facilis Csy., has also been taken by Mr. Frost at Sherborn, Mass. Pristodactyla De}. The following is one of the semiopaque species allied to arizonica, binaria and scolopax: Pristodactyla juabitica n. sp—Moderately ventricose, rather depressed, piceo- rufous, the under surface and legs dark rufous, feebly shining, the elytra opaque; head slightly longer than wide, two-thirds as wide as the prothorax, the anterior impressions large, wide and irregular; eyes well developed but not very prominent; antenne rather long, obscure rufous, the third joint fully a third longer than the fourth; prothorax a fifth wider than long, widest well beyond the middle, the broadly arcuate sides slightly oblique behind, distinctly and evenly reflexed throughout, the angles broadly rounded; base distinctly narrower than the apex, which is only just visibly sinuate and with widely rounded angles; surface smooth, with a few rugule basally; median line fine; latero-basal impression shallow, elongate; elytra three-fifths longer than wide, gradually rounded at apex, with parallel sides, more rounding basally, three-sevenths wider than the prothorax; strie fine; intervals virtually flat, the third with two punctures near the second stria; scutellar stria long, somewhat disintegrated, free. Length (9) 10.5 mm.; width 3.8 mm. Utah (Trout Creek, Juab Co.),—Spalding. This species differs from the male type of arizonica in its more abbreviated outline and especially much shorter prothorax, which has a fine and sharply marked anterior transverse impression, wholly traceless in avizonica, and two more widely separated, and not three, punctures of the third strial interspace. The antennal joints are much less elongate and, in the latter species, the third and fourth joints are equal. Cymindis Latr. This is a large genus in the temperate regions of North America. In my previous revision of the species I have certainly misidentified unicolor Kirby, the prothorax having no ‘‘longitudinal channel” and the “lateral margin of the thorax not dilated,” the length is 88 MEMOIRS ON THE COLEOPTERA 7 mm.; it is said to be thickly punctured and ferruginous, these remarks covering the entire description. LeConte thought that it might be the same as neglecta Hald., but this has a distinct median thoracic line and the surface is not at all closely punctured. This species which I formerly described under the name marginata Kirby (Mem. Col., IV., p. 183) is quite certainly not correctly identified; it is found in a different geographic region, is smaller in size and there is no transverse rugulosity between the eyes; I therefore describe this specimen as the representative of a new species as follows: Cymindis kirbyi n. sp.—Moderately depressed, shining, pale piceous, the broadly reflexed thoracic margins and most of the elytra, median parts of the under surface of the hind body and the legs pale testaceous; head rather more . than three-fourths as wide as the prothorax, very coarsely, closely punctured, more finely and remotely medio-anteriad; eyes moderately prominent; antenne very long, two-thirds as long as the body, testaceous, the third joint longer than the fourth; prothorax a third wider than long, widest near apical third, but with evenly arcuate sides, very briefly sinuate near the rather blunt but prominent hind angles; base wider than the distinctly sinuate apex, the latter having broadly rounded angles; surface coarsely and closely punctate, with fine and imperfect median line; elytra a third longer than wide, two-thirds wider than the prothorax, distinctly widest behind the middle; strie strong but shallow, closely, rather coarsely punctate; intervals feebly convex, moderately, somewhat loosely and confusedly punctate; pubescence very short, sparse and erect; anterior male tarsi feebly dilated and convex. Length (<7) 8.35 mm.; width 3.2mm. _ British Columbia (Caribou District). A peculiar species of the cribricollis section but much smaller, paler and with relatively longer antenne. Reflexa Lec., is allied closely to cribricollis, but the sides of the prothorax toward base are more strongly sinuate and for a decidedly greater distance. Cymindis parowana n. sp.—Rather small and slender, shining, blackish-piceous, the legs very obscure rufous; head slightly elongate, fully five-sixths as wide as the prothorax, with moderate but very prominent eyes and strong close punctures, nearly wanting medio-apically; antenne not quite half as long as the body, piceo-rufous, the third joint evidently longer than the fourth; prothorax slightly wider than long, convex, widest between apical third and fourth, the moderately reflexed sides anteriorly prominently rounded, thence oblique to the evident basal sinuation, becoming straight and parallel to the angles, which are a little more than right, very sharp and strongly reflexed; base oblique at the sides, scarcely over three-fourths as wide as the apex, which is scarcely perceptibly sinuate and with obtuse angles; surface coarsely and closely punctate, with fine and imperfect median line; elytra somewhat less than one-half longer than wide, slightly widest behind the middle, not quite twice as wide as the prothorax; striz rather coarse, not deep, punctate; intervals flat, with coarse separated punctures, somewhat less coarse externally; scutellar stria very short; anterior male tarsi very feebly thickened. Length (72) 8.0 mm.; width 2.8 mm. Utah (Parowan Mts., 10000 ft. elev.). ADDITIONS TO NORTH AMERICAN COLEOPTERA 89 May be placed near wniseriata, but with closer and finer inter- stitial punctures, not at all serial in arrangement. Cymindis planifera n. sp.—Broader, more feebly ventricose, shining, the elytra somewhat less so, blackish-piceous, the elytra feebly rufescent at base, more broadly at the humeri; under surface black, the legs rufous; head three-fourths as wide as the prothorax, with well-developed and prominent eyes, the surface strongly, loosely punctate; antennz slender, piceo-rufous, the third joint longer than the fourth; prothorax nearly two-fifths wider than long, inflated and with evenly rounded sides anteriorly, the sides broadly and strongly reflexed through- out, only minutely sinuate at the basal angles, which are more than right; base as wide as the apex, which is distinctly sinuate, with broadly rounded angles; surface strongly, loosely punctate throughout, with fine imperfect median line; elytra not quite one-half longer than wide, slightly widest behind, three-sevenths wider than the prothorax, with moderate and shallow, closely punctate strie; intervals flat, equal, with rather strong and well-separated punctures, generally confused but sometimes forming two lines; scutellar stria rather short, fine as usual; anterior male tarsi feebly thickened. Length () 8.8 mm.; width 3.18 mm. A single specimen, unlabeled in the Levette collection but probably from Colorado. This species was formerly held to be the wnzcolor of Kirby, but it is quite evidently different, as may be judged by remarks quoted above. Cymindis govanica n. sp.—Only feebly ventricose and convex, strongly shining, piceous-black, the elytra nubilously rufous toward the humeri; under surface and legs rufous; head fully three-fourths as wide as the prothorax, rather strongly but very loosely punctate, with moderate and but slightly prominent eyes; an- tenne slender, rufo-piceous, the third joint barely longer than the fourth; pro- thorax piceo-rufous, the broadly and strongly reflexed sides paler rufous, shorter, about one-half wider than long, the sides parallel and arcuate in about apical half, thence converging posteriad, becoming gradually and moderately sinuate toward the angles, which are somewhat blunt and but slightly prominent; base wide though evidently narrower than the apex, which is broadly and distinctly sinuate, with rounded angles; surface moderately convex, with coarse and widely separated punctures, even throughout, the median line strongly impressed, abbreviated; elytra short, a third longer than wide, less than one-half wider than the prothorax, barely discernibly widest posteriad; striz strong but shallow, closely, moderately punctate, the intervals virtually flat, with widely separated and rather strong punctures, generally confused but sometimes in single uneven series. Length (2) 9.2 mm.; width 3.3 mm. Washington State (Govan). Belongs to the cribricollis section, but with shorter prothorax, having the sides much less sinuate basally and with stronger and sparser elytral punctures, among other noticeable differences. Cymindis obliqua n. sp.—Shining, moderately convex, black, the elytra very faintly rufescent toward the humeri, the wide reflexed thoracic and narrower elytral margins testaceous; under Surface blackish, the hind body broadly rufous medially, the legs rufous; head fully three-fourths as wide as the prothorax, with well-developed and prominent eyes, coarsely, rather loosely punctate, subpunctureless antero-medially; antenne slender, rufescent, the third joint but very little longer than the fourth; prothorax less transverse, a third wider than 90 MEMOIRS ON THE COLEOPTERA long, widest near apical third, the sides subevenly arcuate, converging posteriad, just visibly sinuate near the angles, which are obtuse and evidently rounded, though somewhat prominent; base broad, arcuate, nearly as wide as the distinctly sinuate apex, the latter having broadly rounded angles; punctures strong, moderately separated, sparse antero-medially, the median line extremely fine, imperfect; elytra longer, fully one-half longer than wide, gradually and evenly wider, with nearly straight sides, widest behind the middle, nearly one-half wider than the prothorax, the humeri rapidly circularly rounded; strie strong but superficial, closely punctate, more coarsely basally than apically, the scutellar rather short; intervals flat, with somewhat fine, evenly confused and very moderately separated punctures. Length (2) 9.3 mm.; width 3.35 mm. Canada (Edmonton, Alberta),—Carr. May be placed near the last, though differing in its more elongate form and finer elytral punctuation, as well as several other features. Cymindis sinuata n. sp.—Piceous, the elytra obscure rufous; widely reflexed sides of the prothorax, most of the under surface and the legs pale testaceous; surface shining, the elytra subalutaceous; head more than three-fourths as wide as the prothorax, convex, strongly and closely punctate, sparsely so medially and with prominent eyes; antenne testaceous, the third joint nearly a third longer than the fourth; prothorax a third wider than long, widest near apical third, the sides evenly rounded, becoming broadly sinuate for a long distance before the angles, which are rather obtuse though prominent; base arcuate at the sides, as wide as the sinuate apex, the latter having broadly rounded angles; surface rapidly convex toward the middle, subevenly and strongly, rather loosely punctate, with feeble median line; elytra two-fifths longer than wide, two-fifths wider than the prothorax, slightly widest just behind the middle; striz coarse and deep, densely but indistinctly punctate; intervals not quite flat, strongly but loosely punctate and with very short sparse pubescence, the third with three distinct punctures. Length (2) 9.0 mm.; width 3.4 mm. New Mexico. Resembles reflexa in the comparatively long basal sinuation of the thoracic sides, but differing in the less transverse prothorax and coarse and much deeper elytral stria, the punctures of which are not distinct and isolated, as they are in the very shallow strie of reflexa. Cymindis alternans n. sp.—Very moderately convex and shining, piceous, the thoracic and elytral margins, under surface and legs rufous; short erect hairs rather abundant; head nearly four-fifths as wide as the prothorax, strongly, loosely punctate, subimpunctate antero-medially; eyes well developed, rather prominent; antennz testaceous, of the usual structure, missing in the type beyond the third joint; prothorax fully two-fifths wider than long, widest at anterior two-fifths, with evenly rounded sides becoming gradually and shallowly sinuate for a long distance before the very obtuse and almost blunt angles; base arcuate, narrower than the distinctly sinuate apex, which has the angles rather narrowly rounded; sides broadly reflexed, with a series of long conspicuous bristles; surface evenly convex, the punctures moderately coarse and well sepa- rated, sparse antero-medially, the impressed stria distinct, not entire; elytra three-sevenths longer than wide, two-fifths wider than the prothorax, with the sides subevenly arcuate, slightly widest behind the middle; striae moderately coarse and shallowly impressed, with rather strong distinct punctures; intervals ADDITIONS TO NoRTH AMERICAN COLEOPTERA OI broadly convex, 2 and 4 much narrower than 3 and 5. Length (@) 9.2 mm.; width 3.2 mm. A single specimen, unlabeled in the Levette collection, but probably from Colorado. This is a distinctly isolated species of the cribricollis section, in its alternating strial intervals among other characters. , Philophuga Mots. This genus bids fair to prove a rather large one in temperate North America, and the three following species are hitherto un- described : Philophuga obscura n. sp.—Moderately convex, shining, with subalutaceous elytra, deep bluish-black in color, greenish beneath, with deep black legs; surface glabrous as usual; head elongate, four-fifths as wide as the prothorax, convex, feebly and sparsely rugose, sparsely punctured basally and densely so in the shallow apical impressions; eyes moderately prominent, the antenne black throughout, moderately long, the third joint much longer than the fourth; pro- thorax a fifth or sixth wider than long, widest well beyond the middle, the sides evenly, rounded, becoming oblique and nearly straight posteriad to the widely obtuse and rather blunt though distinct angles; base arcuate, slightly narrower than the very feebly sinuate apex, the latter having obtuse but narrowly rounded angles; surface convex, transversely rugulose, punctate at apex and at the sides basally, with a deep circular impression near the basal angles, the surface declivous and subexplanate thence to about the middle of the length, finely reflexed thence anteriad; elytra not quite a third longer than wide, widest behind the middle and nearly twice as wide as the prothorax, the sides broadly arcuate; apex transversely arcuato-truncate; striz fine, superficial, with small and separated punctures; intervals virtually flat, with very fine sparse punctures, usually in very uneven single series, the third with two remote discal punctures; scutellar stria well developed. Length (2) 8.0 mm.; width 3.25 mm. New York (Lake George),—Prof. J. F. Kemp. The locality of this species is nearer to the Atlantic coast than any other known to me, all the other species being distributed from Texas and Colorado to California; it is a remarkably isolated species. Philophuga cobaltina n. sp.—Much narrower, ventricose as usual, moderately convex, shining, deep violet-blue, greenish beneath, the legs deep black; head slightly elongate, very nearly equal in width to the prothorax, more greenish, almost smooth, sparsely and moderately punctured toward the sides and base, the anterior impressions coarse; eyes well developed, moderately prominent; antenne slender, black, the first three joints testaceous, the third much longer than the fourth; prothorax slightly wider than long, widest anteriorly as usual, with feebly arcuate sides, oblique and shallowly sinuate basally, the angles obtuse but sharp; base oblique at the sides, nearly as wide as the very shallowly sinuate apex, the latter having distinct though blunt angles; surface nearly smooth, the ruguliform lines fine and faint, declivous, rugulose and punctulate at the sides, the latero-basal impression very small and feeble; elytra two-fifths longer than wide, a little less than twice as wide as the prothorax, widest behind the middle and arcuately truncate at apex as usual; stria moderate, not impressed, rather 92 MEeEMoIRS ON THE COLEOPTERA finely and closely punctate; intervals flat, somewhat strongly, sparsely and unevenly punctate, the two discal punctures of the third barely larger than the other punctures; anterior male tarsi narrowly dilated, parallel. Length (@) 7.2mm.; width 2.5mm. Utah (Trout Creek, Juab Co.),—Spalding. This also is a very distinct species, but resembles pzella in its bicolored antenne; the basal sinus at the sides of the prothorax is much longer than in that species and the elytral striae are not at all impressed as they are rather deeply, as well as more finely and very obscurely punctate, in puella. Philophuga uteana n. sp.—Bright bluish-green in color throughout, the legs black, the femora with feeble greenish glint, shining; head not quite as wide as the prothorax, but little longer than wide, rather finely, sparsely punctured, the apical impressions moderate; eyes moderate, barely at all prominent; antenne black, the first three joints testaceous, the third distinctly longer than the fourth; prothorax slightly though distinctly wider than long, the arcuate sides oblique and nearly straight to the strongly reflexed basal angles, which are obtuse and blunt; base arcuate at the sides, very slightly narrower than the scarcely per- ceptibly sinuate apex; surface strongly and conspicuously, somewhat closely and transversely rugose, punctate at apex and basally, transversely impressed at apex, declivous latero-basally, with large and deep, elongate-oval impression near each angle; elytra less than a third longer than wide, four-fifths wider than the prothorax, more parallel than in the two preceding and only just visibly widest behind the middle; striz not at all impressed, with close-set and distinct punctures; intervals flat, more finely, irregularly and very remotely punctulate; anterior male tarsi a little longer, not quite so thick and more tapering than in cobaltina. Length (@@) 7.5-8.0 mm.; width 2.9-3.15 mm. Utah (Stockton and Eureka),—Spalding. Distinguishable easily from cobaltina by the broader form, coarse and close transverse rugule of the pronotum, larger head and prothorax, finer and more irregular interstitial punctures of the elytra and several other characters. - Lebia Latr. The following is a pallid species of the furcata section, but of a highly distinctive style of elytral marking: Lebia tempeana n. sp.—Broadly ventricose, rather depressed, pale testaceous, the elytra more yellowish; legs pale testaceous, the ends of the femora and tibiz, and also the entire tarsi, black, moderately shining, the elytra rather less so; head large, nearly five-sixths as wide as the prothorax, the eyes large and very prominent, the front even, very finely and loosely subrugulose; antennz moderate, black, the first three joints and small base of the fourth testaceous; prothorax fully four-fifths wider than long, the sides rounded to the apex, which is only two-thirds as wide as the base, just visibly sinuate and without lateral angles, feebly oblique basally to the minutely subprominent but not very sharp basal angles, rather broadly reflexo-deplanate, more widely toward base; surface with fine, loose ruguliform lines, the median stria fine, distinct, not quite entire; elytra slightly widest near apical third, with broadly arcuate sides, scarcely more AppDITIONS TO NoRTH AMERICAN COLEOPTERA 93 than a fourth longer than wide, four-fifths wider than the prothorax, the truncate apex slightly sinuate laterally; humeri broadly rounded; each elytron has a black line, about one-half wider than an interval, from the margin at the humeri to the middle at a slight distance from the apex, also a short, rapidly attenuated line from near the base at inner third, parallel to the suture and ending a little beyond basal fourth; striz very fine, feebly and closely punctulate, the intervals flat. Length (9) 6.0 mm.; width 2.8mm. Arizona (Tempe),—Wade. This is not closely allied to any of the rather numerous species of the furcata group known to me, as may be seen from the nature of the ornamentation. The eyes are larger than in furcata, depicta and others. Chlenius Bon. The species described below belongs to a peculiar group, having the punctures of the elytral striz segregated into short, widely isolated lines and represented thus far more especially by the Californian interruptus of Horn: Chlenius albertanus n. sp.—Short and relatively very broad, moderately convex, black, with rather obscure cupreous lustre, the under surface and legs deep black and shining throughout; head barely over half as wide as the pro- thorax, slightly elongate, with moderate but very prominent eyes and strong mandibles, the anterior impressions small and subpunctiform; front smooth and impunctate, with a few irregular and very feeble rugule; antenne as long as the head and prothorax, wholly black; prothorax short, four-fifths wider than long, the sides feebly arcuate, becoming straight and parallel in basal half; base a third wider than the distinctly sinuate apex, the latter having broadly rounding angles, the basal angles right, slightly blunt; surface with coarse and irregularly sparse punctures, not quite so coarse and dense basally, except toward the sides, where the impression near outer fourth is large and deep; sides broadly reflexed throughout the length; median line strong, not quite entire, paralleled at each side by a regular series of coarse punctures in the type; elytra three-sevenths longer than wide, parallel, with arcuate sides, obtusely rounded at apex, about a fourth or fifth wider than the prothorax; general surface not very coarsely but evenly and subgranularly punctate, each puncture bearing a short grayish hair, the striae very deep, disrupted into short sections; intervals perfectly even throughout and moderately convex; under surface rather finely, sparsely punc- tured. Length (9) 12.5 mm.; width 5.6 mm. Canada (Edmonton, Alberta), —Carr. This is a very distinct species, much larger and broader than interruptus, which I have from Siskiyou Co., California, and it is more coarsely sculptured. From alternatus Horn, the above de- scription will distinguish it at once. Opadius Csy. The following is larger than cordifer Notm., less shining and inhab- its a very different zoological province: Opadius piperi n. sp.—Parallel, convex, alutaceous in lustre, black above and beneath, the legs pale yellowish-rufous; head large, three-fourths as wide as the T. L. Casey, Mem. Col. XI, Mar. 1924.—7 94 MEMOIRS ON THE COLEOPTERA prothorax, with moderate and feebly convex eyes, the apical impressions minute and punctiform; antenne testaceous, scarcely compressed, the medial joints between two and three times as long as wide; prothorax two-fifths wider than long, parallel, inflated but with feebly rounded sides in about anterior half, thence broadly sinuate basally, the angles rather prominent but with somewhat blunt apices; lateral edges finely reflexed and pallescent; surface smooth, scarcely at all punctured basally, the basal impression at outer fourth narrow and moder- ate; median line feebly impressed and fine, not extending to the finely rufescent apex; elytra one-half longer than wide, parallel, at the middle of the evidently arcuate sides only just visibly wider than the prothorax, the apical sinus short and feeble; strie deeply impressed, rather coarse, smooth, only a little deeper apically; intervals broadly convex, alternating slightly in width, impunctate, the third with a small deep median fovea near apical two-fifths; tarsi rather short and thick. Length (2) 9.0 mm.; width 3.6 mm. Michigan (Grayling— near Bay City),—C. V. Piper. This singular species is much larger than either cordatus Lec., or cordifer Notm., not shining and with larger head and notably less prominent eyes; cordatus and cordifer have the pronotum punctulate basally; they are mutually closely allied, but in cordatis the head is a little smaller than in cordifer, and the antenne are more slender and evidently longer; the body is slightly broader; it is from Arizona, cordifer being an inhabitant of the British Columbia regions; it has been taken recently by Prof. Piper at Seattle in Washington State. The anterior male tarsi in this genus are only very feebly swollen. Harpalus Latr. During the past few years the material sent in from many sources has materially increased the number of species, so that now it seems desirable to incorporate these new species with those de- scribed in my revision (Mem. Col., V, 1914, p. 69). The species described by Mr. Notman under the name Harpalus cordifer is, as readily seen from a cotype now at hand, a member of the genus Opadius; it is narrower and more parallel than cordatus Lec. Harpalus convictor Csy., placed in synonymy with viridieneus, proves by recent material from Pennsylvania to be at least sub- specifically different; it has a less transverse prothorax than viridieneus, with the sublateral basal impression, which is there very constant, almost wholly obliterated. A subspecific form of FT. caliginosus Fabr., may also be announced as follows: Harpalus (Megapangus) caliginosus ssp. dux nov.—This subsidiary form is larger than caliginosus, with still much larger head, less transverse prothorax and very much flatter strial intervals of the elytra, also with the general lustre of the body more subopaque. Length (2) 25.5 mm.; width 9.8 mm. Southern Illinois. AppiTions TO NorRTH AMERICAN COLEOPTERA 95 The original type of this form was alluded to in my revision (l. c., p. 71). The largest specimen of the typical caliginosus at hand is a female, 24 by 9.3 mm. in dimensions; it is one of the very few species occurring throughout the country, from the Atlantic to the Pacific, and displays comparatively little variation through- out this vast range. The range of Harpalus (Harpalomerus) amputatus Say. according to ample material in my collection, is from Kansas and New Mexico to Colorado, Utah and Arizona. Of transversus, my series of four specimens is from Utah; it may be distinguished at a glance by its larger size and much more transverse prothorax. Of papagonalis I now have another example, also a female and wholly testaceous- yellow, from Utah. The five following seem also to be true species in this subgenus, and in two cases occupy widely different geographic stations: Harpalus (Harpalomerus) bracatus n. sp.—Subparallel, rather convex, shining and deep black, the elytra (2) opaculate, the fine reflexed margins testaceous; legs black, with piceo-rufous tibie and tarsi, those of the anterior more rufous; head convex, fully three-fifths as wide as the prothorax, with some sparse rugula- tion, the clypeus with sparse longitudinal folds, the eyes prominent; antennze testaceous, almost as long as the head and prothorax, the medial joints on the flatter side fully three-fourths longer than wide; prothorax barely one-half wider than long, widest slightly beyond the middle, the sides subevenly arcuate, all the angles broadly rounded; surface with many widely separated ruguliform furrows, those at apex and medio-basally longitudinal; basal punctures numerous, the inner impression rather deep and longitudinal; elytra three-sevenths longer than wide, a fourth or fifth wider than the prothorax, obtusely rounded at apex, the latter subtransversely, rectilinearly truncate (2), the outer angle broadly rounded; stri# impunctate, sharp and deep, impressed apically, the puncture adhering to the second near apical fifth; intervals nearly flat. Length (2) 10.5 mm.; width 4.2 mm. Utah (Miner’s Peak),—Spalding. Differs from amputatus in its slightly larger size and broader form, absence of metallic coloration and more opaque elytra of the female, also in its much less abbreviated and more strongly rugulose prothorax; consequently it differs in habitus to a marked degree. Harpalus (Harpalomerus) ancillaris n. sp.—Parallel, moderately convex, black and shining, the elytra feebly picescent but without trace of metallic lustre; legs rufo-piceous, the tarsi paler; head and antenne nearly as in amputatus, the latter piceous, the medial joints (co) on the flat side twice as long as wide; pro- thorax nearly as in that species, but not quite so abbreviated and with the surface at the sides basally not at all subexplanate; elytra also as in amputatus, but not so evidently wider than the prothorax and not at all metallic in lustre; anterior and middle tarsi (<7) a little more strongly dilated, similarly pale. Length (o) 10.0-10.3 mm.; width 3.9 mm. Oregon (Columbia River),—Shantz. Two specimens. 96 MEMOIRS ON THE COLEOPTERA Allied to amputatus but more parallel, with less abbreviated prothorax and piceous but not in the least metallic elytra. Harpalus (Harpalomerus) rotundicollis Kirby—Form rather short and broad, ventricose, black, with feeble greenish lustre, not very shining, the elytra opaque (Q); legs as in cuculus; head nearly two-thirds as wide as the prothorax, with very prominent eyes and smooth surface, the anterior impressions small but deep; antennz piceous, nearly as long as the head and prothorax, four-sevenths wider than long, widest slightly beyond the middle; all four angles broadly rounded; surface very smooth, the stria biabbreviated; sides toward base narrowly but abruptly explanate; basal impressions and punctures nearly as in amputatus; elytra much shorter, not two-fifths longer than wide, a fifth wider than the pro- thorax; apex (9) somewhat as in cuculus; strie fine, only a little stronger, but not impressed, distally, the discal puncture deep, near to the second stria at apical fourth; intervals wide and flat. Length (9) 10.0 mm.; width 4.0mm. Canada (Edmonton, Alberta),—Carr. One specimen. Distinguishable at once from amputatus by its shorter, broader form, duller integuments and perfectly flat strial intervals. Harpalus (Harpalomerus) cupreolatus n. sp.—Piceo-rufous, the upper surface darker but with very bright polished subcupreous lustre, the narrow lateral reflexed edges testaceous; head barely four-sevenths as wide as the prothorax, with prominent eyes, the anterior impressions short, deep and subpunctiform; antenne obscure testaceous, slender, as long as the head and prothorax, only slightly compressed, the joints moderately swollen at apex on their narrower sides; prothorax four-sevenths wider than long, parallel, with evenly arcuate sides and broadly rounded angles; base wider than the sinuate apex having rounded angles; surface smooth, with some feeble transverse rugule, the anterior impression distinct medially, the median line very fine, widely biabbreviated; latero-basal surface with rather strong close punctures, the impression at outer fourth deep, oblong; elytra less than one-half longer than wide and a fifth or sixth wider than the prothorax, the sides nearly straight medially; apex obtuse, the male truncature oblique; striz fine, smooth and abrupt, the scutellar moderately long, not free; intervals perfectly flat; anterior male tarsi distinctly dilated through the usual first four joints. Length (@) 10.4 mm.; width 3.9 mm. Washington State (Pullman). Distinguishable from any of the other species of the subgenus in the brilliant cupreous lustre and perfectly flat strial interval; on the third, adjoining the second stria, there is a small puncture at two-thirds. Harpalus (Harpalomerus) cuculus n. sp.—Narrow, subparallel, polished throughout (<), black, with feebly rufescent thoracic margins and elytral suture, wholly devoid of metallic lustre; legs rufous, also the trochanters, the femora black; head relatively large, two-thirds as wide as the prothorax, the eyes prom- inent; antenne testaceous, compressed, about one-half longer than the prothorax, the latter only two-fifths wider than long, subparallel, the sides almost evenly and distinctly arcuate, the basal angles broadly rounded; sides feebly, sparsely punctulate and well reflexed; surface smooth, the basal impressions large, rounded, shallowly concave and strongly, rather closely punctate; elytra one-half longer than wide, barely visibly wider than the prothorax, the apices with straight and ApDDITIONS TO NORTH AMERICAN COLEOPTERA 97 feebly oblique, clearly defined truncature; strie strong, the intervals convex; first and second male tarsi well dilated. Length (o) 9.5 mm.; width 3.4 mm. New Mexico (Las Vegas). One specimen. Remarkably different from amputatus in its much narrower and more parallel form, larger prothorax and absence of metallic lustre. In the pennsylvanicus group, some additional material gives me very good series of several species other than the common erythropus, compar and pennsylvanicus, notably texanus, the twelve specimens demonstrating very well the isolation of this species, as do also the eight examples of dolosus. I am very glad to find also a second specimen of thoracinus—the type being an immature female, sent to me from northern Illinois; the strial intervals are decidedly flatter than in the type. The species is quite different from any other in facies, though allied in some respects to protractus and longicollis. The following are some additional species of this group: Harpalus latescans n. sp.—Oblong, moderately convex, deep black, shining, the elytra less so even in the male; under surface deep black, the legs pale rufous throughout; head smooth, with prominent eyes, scarcely three-fifths as wide as the prothorax, the parallel anterior impressions deep, coarse and linear; antennae ferruginous, long and slender, the medial joints three times as long as wide, only slightly compressed; prothorax large, rather less than a fourth wider than long, the parallel sides very evenly and distinctly arcuate; anterior impression distinct medially, the coarse deep stria extending thence to the basal margin; lateral margins not narrowly impressed, more broadly posteriad, punctate; basal punctures extended, moderate and rather dense, the inner impression linear but shallow and broadly concave; angles obtuse and moderately widely rounded; elytra rather short, three-fifths longer than wide, with parallel and broadly arcuate sides, at the middle a fifth or sixth wider than the prothorax; strie rather coarse and deeply impressed, the scutellar long, free; dorsal puncture wanting as usual in this group; intervals broadly convex, with small separated punctures, sparse or almost wanting on 1, 2 and 4, except basally on the last; anterior male tarsi well dilated, the second joint triangular, fully as long as wide. Length (co) 12.0 mm.; width 4.5 mm. Pennsylvania. This species is allied to vagans Lec., but is relatively shorter and broader in outline, with larger prothorax and much shorter elytra, the frontal impressions linear and not small and punctiform, and the elytral punctures more numerous, being almost wanting on inner half in vagans. The most pronounced difference, however, is in the hind tarsi, which, in the present species, are more slender and much more pubescent throughout, being virtually glabrous above in vagans. Harpalus immixtus n. sp.—Narrow, moderately convex, deep black and moderately shining, the under surface black, the metasternum medially, the coxa and entire legs pale testaceous; head almost two-thirds as wide as the prothorax, with rather large and prominent eyes and small linear anterior frontal strioles; 98 Memoirs ON THE COLEOPTERA antenne slender, testaceous, the medial joints two and one-half times as long as wide; prothorax three-sevenths wider than long, the moderately, subevenly arcuate sides a little more converging anteriorly, somewhat widely reflexed, gradually more broadly so and flatter behind, finely, closely punctate, joining the large, feebly concave latero-basal areas, which are closely punctured, the base abruptly impunctate medially; anterior impression deep, joined to the base by the coarse impressed stria; sublateral basal impressions large, parallel and moderately concave; elytra fully two-thirds longer than wide, nearly a fifth wider than the prothorax, with parallel and slightly arcuate sides; stria rather fine but deeply impressed, the intervals strongly convex, with a few fine punctures arranged near the strie, the eighth almost throughout basally; posterior tarsi subglabrous above, the two anterior (<’) well dilated and sparsely pubescent. Length (@) 10.5 mm.; width 4.6 mm. New York (Adirondack Mts.—Keene Valley),— Kemp. Not closely allied to any other species, but to be placed near vagans in the list; it is smaller and very much narrower, with shorter antenne, more transverse prothorax and has many other incongruities. The following is a very small species of the pennsylvanicus section, which may be placed just after zmmixtus: Harpalus cupiens n. sp.—Rather narrow, moderately convex, alutaceous in lustre (@), piceous in color above and beneath, the legs pale brownish-yellow; head large, fully three-fourths as wide as the prothorax, with notably convex, moderate eyes and very small deep apical impressions; antennz testaceous, compressed, the medial joints twice as long as wide on the flattened sides; pro- thorax two-fifths wider than long, the parallel sides evenly, very moderately arcuate from apex to base, the angles slightly blunt and a little more than right; surface smooth, with rather broadly and feebly impressed median line, closely punctulate toward base, scarcely so medially; basal impression at outer fourth large, shallowly concave and rounded; elytra parallel, four-sevenths longer than wide, at the middle nearly a third wider than the prothorax; striz rather coarse, deep, smooth, the intervals feebly convex, impunctate, the ninth with strong, sparse and narrowly spaced punctures throughout; posterior sinus short, near the apex and shallow. Length (9) 10.2 mm.; width 3.85 mm. Northern Illinois. One specimen. Not closely comparable with any other species and by far the smallest of this group. Harpalus feroculus n. sp.—Rather narrowly elongate-suboval, convex, deep black, polished, the elytra (9) opaculate; under surface black, the median line —also sides of the abdomen—more or less rufescent, the femora and coxe pale testaceous, the tibia and tarsi piceous; head relatively large, three-fourths as wide as the prothorax, with moderate eyes and small punctiform frontal impres- sions; antenne slender, testaceous, much shorter than the head and prothorax, the medial joints about three times as long as wide; prothorax barely a fourth wider than long, parallel, with apex almost as wide as base, the sides very evenly, moderately arcuate, the marginal gutter moderate, punctate as usual; anterior impression feeble but visible, the sulcus uniting it with the base moderate; latero-basal region densely, not very coarsely punctate and broadly, feebly con- cave, except at the sides; punctures finely and sparsely crossing the middle; ApDITIONS TO NORTH AMERICAN COLEOPTERA 99 elytra four-sevenths longer than wide, a fifth wider than the prothorax, the parallel sides broadly arcuate; strie sharp and deep, the intervals not quite flat, with very few minute punctures basally toward the sides, the eighth minutely, sparsely punctate throughout; hind tarsi glabrous, the others finely, sparsely pubescent above. Length (2) 13.5 mm.; width 4.5 mm. Rhode Island (Boston Neck). This species, while associable with erythropus, differs in its more elongate and relatively narrower form, much larger head, longer prothorax and in the punctuation of the elytra of the female. It is represented at present by a single specimen. Harpalus admissus n. sp.—Oblong, subparallel, moderately convex, deep black, moderately shining, the elytra (2) opaculate; under surface piceous, the legs rufous; head large, about three-fourths as wide as the prothorax, with well- developed and moderately prominent eyes; antenne testaceous, almost as long as the head and prothorax, only feebly compressed, thé medial joints about three times as long as wide; prothorax a fourth (<) or a third (@) wider than long, parallel, the sides very evenly, moderately arcuate; marginal gutter deep, punc- tate, dilated but little behind; latero-basal area finely, rather closely punctate, nearly flat, the inner impression longitudinal and distinct; apical impression obsolete, the stria fine, ending at the position of the transverse impression as usual in this group; elytra two-thirds (om), one-half (9), longer than wide, evidently wider than the prothorax, the parallel sides feebly arcuate; strie sharply incised, coarser at apex; intervals feebly convex, nearly flat (@), sub- impunctate throughout, the female with a few small scattered punctures; two anterior tarsi (o) strongly dilated but almost glabrous above. Length (7 @) 12.5-14.0 mm.; width 4.6-4.8 mm. Minnesota (Duluth), New York (Lake Champlain) and Hudson Valley (West Point). Four specimens. In the typical pair from Duluth, the male is more elongate than the female, with longer prothorax and elytra—to a degree not noticeable in any other species; admissus may be placed between the preceding and erythropus; it is larger than the latter and with much larger head. The following species may be placed next to admissus in the list: Harpalus excubans n. sp.—Parallel, rather convex, highly polished throughout (@), piceous-black above, in great part testaceous beneath, the legs pale brownish- flavate; head well developed, rather more than two-thirds as wide as the pro- thorax, with moderate but strongly convex eyes and minute apical impressions; labrum piceous, the mandibles rufous; antenne testaceous, rather long, feebly compressed, on the flattened sides, almost three times as long as wide; prothorax a third wider than long, the subparallel sides broadly, subevenly arcuate, a little more so and feebly converging apically, the basal angles obtuse, with rounded apices; sides with rather deep and finely punctured gutter; surface finely, closely punctured toward base, obsoletely at the middle, with a large, rounded, feebly concave impression at outer fourth; median line distinct, not quite attaining the apex; elytra three-fifths longer than wide, at the middle barely visibly wider than the prothorax, the parallel sides feebly arcuate, the apical sinus rather long, very shallow; striae deeply impressed, exarate apically, smooth, the intervals moderately convex, impunctate; anterior male tarsi strongly dilated, the middle a little less so. Length (@) 13.5 mm.; width 4.7 mm. Rhode Island (Watch Hill),—Wirt Robinson. 100 MEMOIRS ON THE COLEOPTERA More abbreviated than in admissus and piceous-black in color, with more transverse prothorax; the shorter elytra conform more closely with those of the Sonoran nactus and pimalicus. Harpalus paratus n. sp.—Oblong, subparallel, only moderately convex, rather shining, the elytra alutaceous (2), black to more or less piceous, in great part piceo-rufous beneath, the legs rufous; head large, three-fifths to two-thirds as wide as the prothorax, with well-developed prominent eyes; antenna testaceous, not very slender, feebly compressed, the medial joints on the flattened side about twice as long as wide; prothorax short, nearly one-half wider than long, otherwise almost as in compar; elytra one-half to three-fifths longer than wide, a fifth or sixth wider than the prothorax, the parallel sides feebly arcuate; strie distinct, sharply incised, coarse and deeper at apex, the intervals almost flat in both sexes; two anterior tarsi (c*) only moderately dilated and with but very few stiff hairs above; sides of the metasternum sparsely but evidently, the entire metepisterna extremely minutely and sparsely, punctulate. Length (co 2) 12.5-14.7 mm.; width 4.75-5.6 mm. Colorado (Akron and Larimer Co.). Six specimens. A distinctly characterized species of the pennsylvanicus group that may be placed near compar in the list; it has a very much more abbreviated prothorax, among other differences. The characters used to discriminate the viduwus and fraternus groups are apparently not usefully effective, and I have therefore assigned the numerous new forms, here brought to notice, to positions merely with reference to described species, disregarding groups. It will be very difficult to define clearly delimited sections in this neighborhood, except by general habitus; for instance, a large head or a small or moderate head might form a convenient basis for two major sections, more easily observable than those derived from accessory abdominal sete and quite as effective taxonomically. Under this system species from patronus to recisus, inciuding lewtsz, fraternus and lecontet, would form one section and the remaining host of smaller species another. Of the described species in the widuus and fraternus groups, as defined by the author, many specimens of /Jewzsi, lecontei and fraternus have been received. One male of fraternus is so much larger than any of the others, less shining and with such different habitus, that it may form a subspecies as follows: Harpalus fraternus ssp. nimius noy.—Larger than fraternus, with rather less polished integuments in the male, the antenne compressed, longer; prothorax larger; elytra nearly similar, but with the apical sinuses deeper; hind tarsi notably longer; coloration similar. Length (co) 14.5 mm.; width 5.8 mm. Oregon (Columbia River). The dimensions of the eleven males of fraternus in my collection are 12.0-13.7 by 5.0-5.5 mm. Of oregonensis I have an additional ADDITIONS TO NORTH AMERICAN COLEOPTERA 101 specimen from Corvallis, of pumilio another exactly similar female from Edmonton, Alberta, of placidus other specimens from Frost, numerous examples of somnulentus, from various parts of Washing- ton State and British Columbia, specimens of lacustris from Mar- quette, many specimens of oblongus from various parts of Utah and also Wawawai, Washington State—the color is deep black, the type being immature—and one additional example of curticornis, from Colorado. ¢ A large series of Jewist received from Mr. Sherman, shows that @sopus, described by me from Lake Champlain, is truly a synonym. At the time of the revision my only representative of lewisi was a female specimen in immature condition. It has also been sent to me from Maine by Mr. Frost. Of lividulus, described from Wisconsin, I now have specimens from New Mexico, from Maryland (Hagerstown) and Virginia (Norfolk); it is allied to herbivagus Say, but is smaller and black, with piceous elytra; the male is more abundant than the female, the contrary being the case in herbivagus. The two following species may be placed near providens Csy.: Harpalus prestans n. sp.—Oblong, convex, very deep black, shining, the elytra (2) opaque; under surface and legs throughout black; head over two- thirds as wide as the prothorax, with small punctiform apical frontal impressions and moderate but prominent eyes; antenne piceous, the first three joints black, only a third longer than the prothorax, the medial joints more or less than twice as long as wide; prothorax scarcely one-half wider than long, parallel, with feebly arcuate sides, straight basally, the angles but little more than right and distinct, only very narrowly blunt; transverse impressions almost obsolete, the stria very fine; latero-basal parts flattened, impunctate, except the broad inner impression, which is moderately punctate; lateral gutter gradually obsolete toward base; elytra scarcely over one-half longer than wide, a fourth or fifth wider than the prothorax, with parallel and broadly arcuate sides; striz fine but sharply incised, coarse and impressed on the declivity, the scutellar long; intervals wide, nearly flat, impunctate. Length (9) 13.0 mm.; width 5.5mm. Utah (Provo Cafion), —Spalding. Easily separable from providens (2) by the shorter prothorax and longer, apically more obtuse, elytra, much more prominent eyes and many other structures. Harpalus animosus n. sp.—Much narrower, convex, similar in color and lustre; head three-fourths as wide as the prothorax, with small but deep punctiform frontal impressions, the eyes rather small and feebly convex; antenne scarcely one-half longer than the prothorax, nearly as in prestans; prothorax shorter, rather more than one-half wider than the median length, the sides parallel, moder- ately but very equally arcuate, not straighter toward base, the angles more obtuse, with broadly and roundly blunt tips; surface nearly as in the preceding, the transverse rugule toward the middle more distinct, the inner basal impression deeper and more narrowly linear, the surface thence to the sides not so flat and 102 MEMOIRS ON THE COLEOPTERA more distinctly though not strongly rugulose; elytra three-fifths longer than wide, scarcely a fifth wider than the prothorax, the sides parallel; striae almost similar but not so coarse or impressed apically, the scutellar much shorter; ‘intervals virtually flat, the opacity (9) brokenly sericeous and not equal throughout, as it isin prestans. Length (2) 14.0 mm.; width 4.85 mm. Utah (Miner's Peak), —Spalding. Differs from pre@stans in its much narrower outline, similarly large head but with smaller and far less prominent eyes, shorter prothorax, with much more narrowly rounded apical angles, the basal differing as stated, and in the different character of elytral opacity in the female. Harpalus fanaticus n. sp.—Size very moderate, subparallel, convex, deep black, shining, the elytra (9) subsericeous, alutaceous; under surface and legs piceo-rufous; head notably large, almost four-fifths as wide as the prothorax, the eyes very moderate but prominent; frontal impressions small, short, deep and sublinear; antenne testaceous, one-half longer than the prothorax, distinctly compressed; prothorax almost one-half wider than long, widest slightly beyond the middle, the sides distinctly arcuate, gradually less so basally, the angles obtuse and bluntly rounded; apex broadly sinuate, with rounded angles; surface with subobsolete transverse impressions and fine abbreviated stria; latero-basal region virtually impunctate, the inner impression rather deep, linear, with a few minute punctules; elytra only two-fifths longer than wide, nearly a fourth wider than the prothorax, with parallel and broadly arcuate sides; stria moderate, not very deep, coarser and impressed distally, the scutellar long; intervals broadly, feebly convex, impunctate. Length (@) 10.0 mm.; width 3.8 mm. Utah (The Mammoth—Summit of Parowan Mts.—elev. 1oo0o ft.),—Knaus. Much smaller than either of the two preceding and not closely allied to any known species. ; Harpalus amiculus n. sp.—Still much smaller, parallel, convex, deep black and polished throughout (o”); under surface shining, black, the epipleura narrow and paler; legs pale rufous throughout; head fully two-thirds as wide as the prothorax, the eyes moderate and notably prominent; apical impressions minute and punctiform; antenne testaceous, slender, about as long as the head and prothorax, the latter only two-fifths wider than long, parallel, with moderately and evenly arcuate sides and broadly rounded basal angles; surface with shallow transverse impressions and fine subentire stria; reflexed sides and the basal margin diaphanously rufous, the former very fine apically, gradually wider, turning inward and moderately punctate posteriad; inner impression rounded, shallow and punctate, the surface along the rounded angles tumid; elytra two- fifths longer than wide, as wide as the prothorax, the parallel sides broadly arcuate; striae strong, deep and impressed, the intervals convex and impunctate; two anterior tarsi (c”) moderately dilated. Length (co) 8.0mm.; width 3.0 mm. New York (Lake George),—Kemp. There is no other species with which this can be compared in any way closely, except recisus. It is much smaller. than recisus— of which I have recently received another blacker female specimen from I]linois—and narrower in outline, with more deeply sinuate AppITIONS TO NORTH AMERICAN COLEOPTERA 103 thoracic apex and more uneven latero-basal parts of the surface, also shorter and more slender hind tarsi. The following is a remarkably parallel and rectilinear species that may be placed near fenisex: Harpalus spaldingi n. sp.—Parallel, moderately convex, shining, blackish- piceous, very shining and black beneath, the legs bright rufous; head large, between two-thirds and three-fourths as wide as the prothorax, with rather large and, subprominent eyes and minute punctiform strioles; surface very smooth; antenne rather slender, rufous; prothorax long, only three-sevenths wider than long, the parallel sides evenly and very moderately arcuate throughout; sides punctulate and narrowly reflexed, more broadly and deplanately toward base; angles all rounded; surface very smooth, with moderate and apically abbreviated stria, the transverse impressions obsolescent; basal impression at outer fourth broad, shallow and moderately punctate, feebly but finely linear along the bottom, the surface thence to the sides very minutely, loosely punctulate; base but slightly wider than the apex; elytra two-thirds longer than wide, not evidently wider than the prothorax, the sides nearly straight; apex gradually rounded, the sinus long and very feeble; striae abrupt, deep, smooth, the scutellar rather long, free; intervals almost flat, impunctate; first male tarsi rather broadly dilated, the second a little less so. Length (@) 12.6 mm.; width 4.2mm. Utah (Vineyard),—Mr. Tom Spalding. One specimen. ’ This species seems to be very distinct and may be recognized by the rectilinearly parallel form and rather long, subquadrate pro- thorax, among other characters. Harpalus conspectus n. sp.—Oblong-suboval, convex, smooth, shining, the elytra not appreciably duller in the female, black, with fine testaceous edges, the elytra with greenish-metallic lustre; under surface black, the legs pale yellowish- testaceous; head longer than wide, nearly two-thirds as wide as the prothorax, the eyes well developed but only feebly convex; antenne scarcely one-half longer than the head, testaceous, somewhat compressed; prothorax three-sevenths wider than long, the sides parallel, subevenly and feebly arcuate; transverse impressions subobsolete, the stria very fine and evanescent; side margins un- usually finely reflexed; latero-basal region convex, impunctate, the inner im- pression rather deep but finely linear; elytra oblong-oval, three-sevenths longer than wide, parallel, with rather strongly arcuate sides and fully a fourth wider than the prothorax; stri# impunctate, strong but shallow, deep and impressed on the declivity, the scutellar proceeding from a post-basal puncture adjoining the second stria; intervals nearly flat, narrow and convex on the declivity. Length (2) 8.2 mm.; width 3.3mm. Canada (Mt. Royal, Quebec). I am at a loss to place this species, especially in the absence of the male. It might come near Jacustris and species of that section, because of the subscutellar fovea, but the relatively longer head and the metallic coloration, isolate it there; perhaps it may as well come after vecisus and amiculus. Harpalus reversus n. sp.—Oblong, subparallel, rather convex, deep black and highly polished throughout (2); under surface and legs black; head fully three- fifths as wide as the prothorax, with well-developed, prominent eyes, the apical 104 MEMOIRS ON THE COLEOPTERA frontal impressions very small, punctiform; antenne piceo-rufous, one-half longer than the prothorax, the latter one-half wider than long, the parallel sides feebly arcuate, straight to faintly sinuate behind the middle; basal angles only slightly blunt, the apical broadly rounded; surface with sparse feeble rugule in part, the anterior impression very feeble; latero-basal surface closely punctate and subrugose, the inner impression but feebly differentiated; lateral relexed margins translucently testaceous; elytra one-half longer than wide, a sixth wider than the prothorax, with parallel and feebly arcuate sides; stria rather strong, sharply incised; intervals nearly flat, feebly convex distally. Length (2) 10.4-12.3 mm.; width 4.4~-4.8 mm. Michigan (Marquette),—Sherman. Seven specimens. This is a very remarkable species of moderately large size, because of its extreme resemblance in outward appearance to lecontet (oblitus || Lec.). In the latter species the elytra in the female are always subopaque, while here they are shining, with varnish-like lustre; the male is not at hand at present. In rufi- ‘manus Lec., the size is much smaller and narrower and the elytra are opaculate in the female; /econtez is represented by a large series from various regions in western Texas, New Mexico, Arizona, Colorado and Utah; the sides of the prothorax are feebly arcuate basally and not straight or broadly sinuate, as they are in reversus. The following belongs near /ividulus but is narrower, with smaller head and with more metallic coloration: Harpalus agitabilis n. sp.—Small, rather convex, oblong-suboval, polished black, the elytra with greenish-metallic lustre, the margins of the prothorax diaphanously testaceous; under surface black, the legs rufo-testaceous; head rather longer than wide, barely three-fifths as wide as the prothorax, with minute and feeble distal impressions, the eyes only moderately convex; antenne testa- ceous, scarcely as long as the head and prothorax, the latter not quite one-half wider than long, widest at a little beyond the middle, the sides broadly arcuate, less so posteriad, the angles blunt; surface wholly impunctate, the transverse impressions very faint; inner basal impression very feeble and broadly linear; elytra parallel, with distinctly arcuate sides, two-fifths longer than wide, almost a third wider than the prothorax; striz rather fine but incised, barely at all coarser on the declivity, the scutellar fine, extending from a strong puncture; intervals flat, narrower but not convex distally; first two male tarsi rather narrowly dilated. Length (o) 7.6 mm.; width 2.8mm. District of Columbia. One specimen. The type is easily distinguishable from the male of lividulus by its much narrower head and prothorax, shorter and more finely striated elytra, with metallic lustre, and many other characters. Harpalus columbianus n. sp.—Oblong, parallel, notably convex, polished (<7) and deep black; under surface black, the femora black, the two anterior coxe and all the tibiz and tarsi dark rufous; head four-sevenths as wide as the pro- thorax, fully as long as wide, with moderate but notably prominent eyes, the apical impressions minute but incised and linear; antennz almost as long as the head and prothorax, testaceous; prothorax barely one-half wider than long, the - subparallel sides feebly arcuate, the basal and apical angles subequally and widely rounded; surface smooth, convex, impunctate, the transverse impressions ADDITIONS TO NORTH AMERICAN COLEOPTERA 105 vague and very faint, the inner basal linear, impressed and minutely, feebly punctulate; elytra nearly one-half longer than wide, about equal in width to the prothorax, with parallel and feebly arcuate sides and obtuse apex; striz fine, the scutellar with anterior puncture; intervals flat, still wide and barely at all convex distally. Length (co) 9.75 mm.; width 3.8 mm. British Columbia (Goldstream). The male type is separable very easily from pellax, to which it is most closely allied, by the narrower head and prothorax, much finer elytral striation and especially by the more narrowly dilated anterior and middle tarsi; in both, the side margins of the prothorax are very finely reflexed and not obviously diaphanously paler, and the discal elytral puncture is near apical fourth to fifth. Harpalus obnixus n. sp.—Subparallel, rather convex, deep black, the under _ surface and legs black, with piceous coxe, tibie and tarsi; elytra (2) opaculate; head (co) four-sevenths as wide as the prothorax, nearly three-fifths (2), with moderate but rather prominent eyes, the antenne slender, testaceous and as long as the head and prothorax, the latter only a third wider than long (<7), or two-fifths (@), smooth, impunctate, the basal parts very feebly subrugulose, with some short longitudinal folds medio-basally; transverse impressions virtually obsolete, the stria fine and feeble, much abbreviated as usual; sides parallel, very moderately and subevenly arcuate, with subequally and widely rounded apical and basal angles and finely reflexed side margins; elytra one-half (<7), or two- fifths (9), longer than wide, very slightly wider than the prothorax, the parallel sides feebly but evidently arcuate; strie fine but incised, not evidently coarser distally; intervals almost flat, opaque in the female; two anterior male tarsi rather strongly dilated. Length (9) 9.0-10.4 mm.; width 3.65-4.0 mm. Utah (Provo Cafion),—Spalding. Three specimens. This distinct species may be assigned a place near peritus, from Reno, Nevada, the male differing from the same sex of peritus in its narrower head, with smaller eyes, much longer prothorax, with the basal punctuation of that species wanting, in its longer antenne and in many other structural features. Harpalus parowanus n. sp.—Subparallel, moderately convex, deep black and highly polished throughout (); under surface black, the legs ferruginous, with black femora; head nearly three-fourths as wide as the prothorax, the eyes moder- ate and only very moderately convex; apical impressions very small, the antenne testaceous, almost as long as the head and prothorcax, the latter rather short, somewhat over one-half wider than long, the sides parallel, evenly and moderately arcuate, the obtuse basal angles broadly rounded, the apical about similar; side margins very narrowly reflexed, feebly rufescent; anterior impression evident toward the middle; basal fovee broadly, feebly impressed, with some fine obsolescent ruguliform punctulation; elytra two-fifths longer than wide, a fifth wider than the prothorax, with parallel and broadly arcuate sides and obtusely rounded apex; strie rather coarsely incised, deeper and impressed distally, the scutellar long, with anterior puncture, the discal puncture near three-fourths; intervals broadly, feebly convex, narrower and more strongly ° so on the declivity; two anterior male tarsi well dilated. Length (@) 9.0 mm.; width 3.4 mm. Utah (The Mammoth, Parowan Mts.—10000 feet). 106 MEMOIRS ON THE COLEOPTERA A distinctly characterized species, which for the present may follow the last, but the relatively large head may necessitate its removal to the vicinity of Jeconte: and other much larger species. Harpalus contactus n. sp.—Narrower, moderately convex, rather shining, black, the side margins of the prothorax diaphanously rufous; under surface black, the legs rufo-piceous, the femora blacker; head two-thirds as wide as the prothorax, with rather long neck, prominent eyes and small anterior foveoles; antenne testaceous, not quite so long as the head and prothorax, the latter somewhat more than one-half wider than long, the sides broadly arcuate, nearly straight posteriad; transverse impressions feeble but evident; inner basal fovea large, broadly impressed and rather closely punctulate; basal angles moderately rounded, the apical more broadly; elytra nearly one-half longer than wide, very slightly wider than the prothorax, the parallel sides broadly arcuate, incised strie relatively rather strong, coarse and impressed on the declivity, the scutellar short, with puncture; intervals feebly convex, more so on the declivity; anterior male tarsi well dilated but short, the third and fourth joints unusually short and transverse. Length (co) 8.4 mm.; width 3.3 mm. Utah (Cedar City),— Spalding. May be placed next to the preceding species; it does not seem to be closely allied to any other; the anterior male tarsal joints are unusually transverse. Harpalus uintanus n. sp.—Larger and broader, the habitus more nearly as in columbianus, deep black and polished (co); under surface black, the legs fusco- rufous, the femora black; head rather large, two-thirds as wide as the prothorax, with long neck, prominent eyes and small but deep impressions; antenne testa- ceous, distinctly shorter than the head and prothorax, the latter large, not three- sevenths wider than long, widest near apical two-fifths, the moderately arcuate sides becoming nearly straight in basal half; all four angles rather broadly rounded; margins only very finely reflexed; impressions subobsolete, the abbreviated stria fine, entire; base, except medially, punctulate, the punctures of the broadly impressed inner foveze close and distinct, thence minute, sparse and indistinct to the sides; elytra three-sevenths longer than wide, not distinctly wider than the prothorax, the parallel sides feebly arcuate, the apex obtuse; striz moderate but deeply incised, the scutellar long, with anterior puncture; intervals feebly convex, more so on the declivity; anterior male tarsi well dilated, the joints gradually diminishing in width and length. Length (o) 9.4 mm.; width 3.7 mm. Utah (Cedar City),—Spalding. Differs very much from contactus in its larger size, less transverse prothorax, much longer scutellar stria and other characters; al- though well developed, the head is relatively not so large as in parowanus. Harpalus antiphon n. sp.—Much smaller, rather convex, deep black, shining, the elytra slightly alutaceous (2); under surface black, the legs piceo-rufous, the femora somewhat darker; head four-sevenths as wide as the prothorax, with rather long neck and notably prominent, moderate eyes; antenne slender, testa- ceous, four-fifths as long as the head and prothorax, the latter three-sevenths wider than long, the subparallel sides feebly arcuate, gradually more so and a little more converging anteriad; four angles well rounded; margins very finely Appitions TO NortH AMERICAN COLEOPTERA 107 reflexed, feebly rufescent; surface smooth and wholly impunctate, with the impressions at best vestigial; inner basal impressions narrow, linear and feeble, with a few minute punctules at the bottom; elytra nearly three-sevenths longer than wide, subequal in width to the prothorax, the parallel sides only feebly arcuate; strie finely incised, the scutellar short, with the usual puncture of this section; intervals flat. Length (9) 7.8 mm.; width 2.85 mm. New Mexico (Jemez Springs). This species and the following may come next to ellipsis Lec., but they are smaller and much narrower. Harpalus fractus n. sp.—Similar in size to the preceding, subparallel and convex, deep black, wholly polished (co), with alutaceous elytra (92); under surface black, the entire legs and tarsi piceous-black; head moderate, four- sevenths as wide as the prothorax, the eyes and antenne nearly as in the pre- ceding; prothorax subsimilar but longer, only a third wider than long to somewhat less, the surface, sides and fovee almost similar, but with the basal angles less broadly rounded; elytra nearly similar but rather more evidently wider than the prothorax, the parallel sides slightly more arcuate; anterior male tarsi moderately dilated, dark brown in color. Length (%@) 7.7 mm.; width 3.0-3.1 mm. Colorado (Akron),—Shantz. Closely allied to antiphon, but recognizable by the less narrow or parallel outline, more arcuate sides of the elytra and much less transverse prothorax. The two following species may be placed near mobilis, but have a relatively larger head: Harpalus instructus n. sp.—Subparallel, moderately convex, deep black and strongly shining, the elytra alutaceous in the female; under surface and legs black, the tarsi piceous; head rather large, fully three-fifths as wide as the pro- thorax, subequal in the sexes, the eyes well developed and moderately prominent, the apical impressions small, deep and punctiform; antenne testaceous, one-half longer than the prothorax, the latter a third to three-sevenths wider than long, the parallel sides feebly and subevenly arcuate, the basal angles much less broadly rounded than the apical; side margins very finely reflexed, gradually subdeplan- ately broader behind; surface nearly smooth, the inner basal impression broad, shallowly concave and finely, rather closely punctulate; elytra one-half longer than wide—three-sevenths (<)—slightly wider than the prothorax, with the parallel sides evidently arcuate; strie distinct, evenly incised, more impressed distad; intervals nearly flat in both sexes; anterior male tarsi broadly, the second distinctly less, dilated. Length (@@) 10.0-10.4 mm.; width 4.0-4.1 mm. Canada (Edmonton, Alberta). Three specimens. The prothorax, as well as the elytra, is distinctly shorter in the male than in the female. The head is very much larger than in mobilis, and the basal thoracic impressions are of an entirely different kind; in mobilis they are subobsolete and narrowly linear. Harpalus assensus n. sp.—Parallel, rather convex, shining, with faintly alu- taceous elytra (<7), the lateral and basal thoracic edges diaphanously rufous; under surface black, the epipleura, middle of the metasternum and entire legs 108 MEMOIRS ON THE COLEOPTERA testaceous; head relatively large, two-thirds as wide as the prothorax, with well- developed and prominent eyes, the apical impressions minute; antenne pale testaceous, one-half longer than the prothorax, the latter three-sevenths wider than long, the parallel sides distinctly and subevenly arcuate; basal angles very broadly rounded, much more so than the apical; surface smooth, impunctate, the inner basal impression large, broadly and feebly concave and finely, closely punctulate or rugulose; elytra rather more than one-half longer than wide, not evideritly wider than the prothorax, gradually rounding behind, the parallel sides feebly arcuate; striae very moderate, incised, the intervals virtually flat; anterior and middle male tarsi distinctly but moderately dilated. Length (co) 9.8 mm.; width 3.3 mm. Colorado (Boulder Co.),—Cockerell. One specimen. A very distinct species, notable among other features in the very broadly rounded basal thoracic angles. Harpalus maxwelli n. sp.—Small, parallel, convex, pale testaceous throughout and polished; head nearly two-thirds as wide as the prothorax, the eyes moderate but very prominent; anterior strioles minute and feeble, linear; antenne not quite attaining the thoracic base, pale testaceous, only moderately slender, compressed; palpi and mandibles testaceous, the latter black distally; prothorax four-sevenths wider than long, the parallel sides evenly and not strongly arcuate, the angles slightly obtuse, rather widely rounded; apex slightly narrower than the base, feeblyv sinuate, the angles rounded, not much produced; surface smooth, with some feeble sparse rugule, the median stria extremely fine and imperfect; anterior impression very feeble; basal region rugulose throughout, the impression near outer fourth very shallow, loosely punctate; side margins rather narrowly reflexed, lost in a feebly convex surface at base; elytra three-sevenths longer than wide, parallel, at the middle of the feebly arcuate sides barely visibly wider than the prothorax, rapidly obtusely rounded at apex; strie strong, impressed, smooth, the scutellar rather long, free; intervals convex, the third with a small puncture near the second stria at three-fourths; anterior male tarsi moderately dilated. Length (%) 7.8 mm.; width 2.75 mm. New Mexico (Maxwell),— Wade. A single specimen. The integuments in the type, though very pallid, exhibit no distortion on drying and therefore are probably almost normal, though the color differs so greatly from the prevailing dark tints cf most of the allied species; it may be placed near desertus Lec. Of electus Csy., 1 have received recently two males from Mr. Carr; they differ from the female type only in the slightly more polished elytra; the outline of this species is peculiar. Harpalus blanditus n. sp.—Body small, moderately convex, black to piceous, shining (), with rufescent thoracic margins, the elytra (9) alutaceous; under surface black, the margins piceous, the legs pale rufous; head well developed, with prominent eyes, two-thirds as wide as the prothorax, relatively a little larger in the female, the anterior impressions small, deep, circular and punctiform; antenne testaceous, extending nearly to the thoracic base, somewhat thicker in the female; prothorax nearly one-half wider than the median length, the apex deeply sinuate; sides distinctly and subevenly arcuate; edges finely reflexed; basal and apical angles subequally and not widely rounded; surface nearly smooth, impunctate, the stria biabbreviated; inner basal fovea broadly impressed, closely punctate, thence feebly and sparsely so to the sides; elytra not three-sevenths AppITIONS TO NORTH AMERICAN COLEOPTERA 109 longer than wide, fully a fifth wider than the prothorax, with parallel, slightly arcuate sides; stria rather coarse and moderately impressed, with slightly convex intervals; first two male tarsi rather widely dilated. Length (7 @ ) 7.8-8.0 mm.; width 3.0-3.1 mm. British Columbia (Terrace),—Mrs. Hippisley. May be placed near Jividulus, but narrower and more ventricose. I am rather doubtful as to whether the female specimen associated with the male type really belongs there; it is stouter and the latero-basal punctures of the pronotum are stronger, more widely diffused and much more conspicuous; the basal thoracic angles, also, are more broadly rounded. Harpalus nivalis n. sp.—Oblong, subparallel, black and shining; under surface black, the side margins and legs testaceous; head well developed, two-thirds as wide as the prothorax, with prominent eyes and moderate testaceous antenne; prothorax fully two-fifths wider than long, widest somewhat beyond the middle, with moderately arcuate sides, becoming straighter behind the middle, the angles obtuse and rounded; surface nearly as in the preceding, except that the basal impressions are much more broadly concave and densely and clearly punc- tate, the convex surface thence to the sides with minute, sparse and feeble punctu- lation; elytra almost one-half longer than wide, only very slightly wider than the prothorax, the parallel sides very feebly arcuate; stria rather coarse, especially on the declivity, where they are also impressed; intervals nearly flat; first and second anterior male tarsi equally and rather strongly dilated. Length () 8.4 mm.; width 3.2 mm. Canada (Saskatchewan). One example. Narrower than Jascivus Csy., and larger than blanditus, near both of which it may be placed. A species in my collection seems to satisfy Kirby’s description of basilaris very well; the antenne are blackish, the two basal joints abruptly testaceous. My five specimens were taken at Ottawa and Marquette, Michigan; it was described from Ontario by Kirby. The following three species can come immediately after lustrans Csy. (lucidus || Lec.): Harpalus dulciculus n. sp.—Small in size, subparallel, rather strongly convex, polished in both sexes, the elytra faintly alutaceous in the female, black or faintly piceous, the thoracic margins rufescent, the elytral suture frequently very slightly piceo-rufous; legs rufous; head three-fifths as wide as the prothorax, with prominent eyes; antenne slender, testaceous, one-half longer than the prothorax, the latter very nearly one-half wider than long, widest somewhat beyond the middle, the sides moderately arcuate, straighter posteriad, the angles rather widely rounded; margins well reflexed and punctulate as usual, gradually more broadly behind; surface nearly smooth, the stria very fine, the inner basal impression linear but shallow and broadly impressed, punctulate, the punctures very fine and sparse thence to the sides; apex shallowly sinuate, with rounded angles; elytra nearly one-half longer than wide, shorter (9), only very slightly wider than the prothorax, with parallel and slightly arcuate sides; striae moderate, incised; intervals nearly flat; first two male tarsi only very moderately dilated. Length (o@ 2) 7.3-7.8 mm.; width 2.75-3.1 mm. Colorado (Akron),—Shantz. Four specimens. T. L. Casey, Mem. Col. XI, Mar. 1924.—8 IIo MEMOIRS ON THE COLEOPTERA The single female is rather narrower than any one of the three males. In the following female type the form is shorter and broader, with more impressed striae and convex intervals: Harpalus captiosus n. sp.—Similar in coloration, except that the femora are blackish-piceous; lustre polished, the elytra scarcely less so in the female; head larger, with prominent eyes, almost two-thirds as wide as the prothorax, the pale testaceous antenne a little longer; prothorax somewhat larger and more convex, otherwise similar, except that the sides are parallel and almost evenly, moderately arcuate, the surface near the rounded basal angles with some coarser punctures; elytra much shorter and broader, barely two-fifths longer than wide, a fifth or sixth wider than the prothorax, the sides feebly arcuate; striz coarser, incised, the intervals much more convex. Length (2) 7.5 mm.; width 3.35 mm. Colorado (Akron),—Shantz. One specimen. The female type represents a species somewhat allied to dulciculus but much broader, with larger head and coarser stria, having much more convex intervals. Harpalus metuens n. sp.—Oblong, parallel, deep black, highly polished through- out in the female; legs rufo-piceous; head well developed, nearly two-thirds as wide as the prothorax, with moderate but rather prominent eyes, the apical foveoles minute but linear; antenne testaceous, less than one-half longer than the prothorax, which is only two-fifths wider than long, widest somewhat beyond the middle, the very feebly arcuate sides straight posteriad, the angles moderately rounded; margins narrowly reflexed, somewhat diaphanous; surface nearly smooth, the stria fine; latero-basal region sparsely, irregularly punctate, the fovea sublinear but broad, shallow and very unevenly punctate; elytra only two-fifths longer than wide, a fifth or sixth wider than the prothorax, with feebly arcuate sides and very obtusely rounded apex; striz strong; intervals feebly though evidently convex. Length (9) 7.7-8.0 mm.; width 3.15-3.25 mm. Arizona. Also two specimens from Dodge City and Fort Scott, Kansas, which seem to be conspecific. In comparing the female type of this species with the female of lustrans, it is seen to be decidedly larger in size and of broader form; it is, however, closely allied. In my former work several species were confounded; Justrans is specifically Arizonian. A typical female is 7.2 by 2.75 mm. in dimensions. The following seven species, having the head notably small, are allied more or less closely to oblongus and may follow that species in the list; the first four are allied also to basilaris: Harpalus furviculus n. sp.—Oblong, convex, polished, black, the elytra alu- taceous in the female; under surface, legs and tarsi throughout—even the anterior (o)—deep black; head slightly more than half as wide as the prothorax, four- sevenths (@), with moderately prominent eyes and small punctiform apical impressions; antenne slender, as long as the head and prothorax, blackish, the two basal joints pale testaceous; prothorax one-half wider than long, the sides rounding and converging anteriorly, straight and just visibly oblique in basal half, the angles right, only very narrowly rounded or blunt at tip; surface smooth, ADDITIONS TO NORTH AMERICAN COLEOPTERA III the stria very fine; latero-basal surface rugose, not definitely punctate, shining, the fovea narrow and longitudinal; elytra one-half longer than wide, three- sevenths (2), evidently wider than the prothorax, more notably (92), with feebly arcuate sides and rather gradually rounded apex; strie# strong, coarser and impressed distad; intervals feebly convex, flat (92); first two tarsi (<7) very moderately dilated. Length (2) 7.6-9.2 mm.; width 3.0-3.6 mm. Washington State (Wawawai and Govan), also British Columbia. Six specimens. It will be noted that the antenne are colored as in basilaris and several others of this section, but this species is narrower and less ventricose than the one I have selected to represent basilaris. Harpalus stocktonensis n. sp.—Shorter and stouter than the preceding, convex, slightly ventricose, the color and lustre similar throughout; head ( 9 ) relatively not quite so large, but very little over half as wide as the prothorax, the eyes moderate and still somewhat less prominent; antenn# similar; prothorax similar in form, smooth, with fine stria, but with the latero-basal surface more finely and feebly rugulose, the fovea larger, not so linear and broadly, feebly impressed; elytra nearly as in the female of furviculus, but broader, about a fourth wider than the prothorax; strie distinctly finer, the intervals flat. Length (2) 87 mm.; width 3.85 mm. Utah (Stockton). One specimen. Evidently closely allied to furviculus, but notably broader and differing also in the character of the basal thoracic impressions, as well as in the much finer striation. Harpalus ventricosus n. sp.—Stout, ventricose, shining, black, the elytra opaculate in the female; legs obscure rufous throughout; head nearly four- sevenths as wide as the prothorax, rather short, the eyes very moderately prom- inent, the apical impressions small, deep and punctiform; antenne as in the two preceding, black, the first two joints pale testaceous, the third piceous; prothorax four-sevenths wider than long, with outline as in the two preceding, and with similar right angles only narrowly rounded at tip; surface nearly smooth, the transverse impressions visible medially; latero-basal region finely, sparsely rugulose, not punctate, the inner impression linear, broadly, rather deeply im- pressed and distinct; elytra oblong-oval, with rather strongly arcuate sides, only two-fifths longer than wide and fully a third wider than the prothorax; strie fine, incised, coarse and impressed distad; intervals flat. Length (2) 8.7 mm.; width 3.8 mm. British Columbia (Spencer). One specimen. This very distinct species belongs to the basilaris section and may be allied to obesulus Lec., from Oregon, but in obesulus the prothorax is more transverse, only obsoletely impressed at base, and the elytra are but little wider than the prothorax in the female type; no such unusual difference in thoracic and elytral width, as is here apparent, could give rise to the language of LeConte, “elytra a little wider than the prothorax.”’ Harpalus durescans n. sp.—Oblong, only feebly ventricose, convex, polished, deep black, the elytra (9) only very faintly alutaceous; entire legs and coxe deep black; head ( @) slightly larger than in the same sex of basilaris, fully four- sevenths as wide as the prothorax, rather longer than wide, the eyes prominent; II2 MEMOIRS ON THE COLEOPTERA antenne nearly as in basilaris, but not as long as the head and prothorax, the latter only three-sevenths wider than long, the sides parallel and straight, strongly rounding beyond the middle; hind angles right, scarcely at all blunt at tip, the surface as in baszlaris, the inner impression coarsely linear and deeper; elytra nearly one-half longer than wide, only a sixth wider than the prothorax, the sides feebly arcuate; striz moderate, only moderately coarse distad; intervals nearly flat. Length (2) 8.0mm.; width 3.4mm. Quebec (Ft. Coulonge). Allied to basilaris but more elongate, with much less abbreviated prothorax, larger head and entirely black legs and coxe; the latter in basilaris are always yellow. Harpalus intactus n. sp.—Oblong, slightly ventricose, moderately convex, deep black and shining; legs pale rufous, the femora black, pallescent basally; head four-sevenths as wide as the prothorax, with well-developed prominent eyes and perforate apical impressions; antennz slender, testaceous, as long as the head and prothorax, the latter only about a third wider than long, the sides distinctly arcuate, becoming rather rapidly straight and oblique in basal half, the angles more than right, but with their tips only very narrowly rounded; surface sparsely, finely punctulate and rugulose at base, the inner fovea linear, rather narrow and deep; elytra nearly one-half longer than wide, between a fourth and fifth wider than the prothorax, the strie# moderate, incised, coarser and impressed on the declivity; intervals very feebly convex; first male tarsi rather strongly dilated, the second evidently less so. Length (@) 8.5 mm.; width 3.35 mm. Michigan (Marquette),—Sherman. One specimen. In some respects this species recalls the basi/aris section, as in the distinct basal thoracic angles, but the straight sides of the latter—which is more elongate—are much more oblique, and the coloration of the legs and antenne is very different. Harpalus modulatus n. sp.—Oblong-suboval, rather convex, very moderately shining, the elytra sericeously opaque (@); under surface black, the legs pale rufous; head larger, three-fifths as wide as the prothorax; eyes prominent, the apical foveoles minute; antenne slender, testaceous, less than one-half longer than the prothorax, which is rather less than one-half wider than long, the sides subparallel and feebly arcuate, gradually rounding anteriorly, all four angles rather broadly rounded; impressions diffuse, faintly visible medially; basal region smooth and wholly impunctate, the inner fovea linear but feebly and shal- lowly impressed; elytra only two-fifths longer than wide, between a fifth and sixth wider than the prothorax, obtusely rounded behind, the sides arcuate; strie fine, not much coarser distally; intervals perfectly flat. Length (2) 7.25 mm.; width 3.1mm. Quebec (Ft. Coulonge). One specimen. This species is rather isolated, being allied only to the next, which is larger, more elongate and more parallel. Harpalus leviceps n. sp.—Subparallel, convex, black, rather shining, the elytra opaculate (2); under surface black, the sides and the legs dusky rufous; head fully four-sevenths as wide as the prothorax, with moderate but prominent eyes; antenne slender, testaceous, scarcely one-half longer than the prothorax, the latter parallel, with evenly and distinctly arcuate sides, only about two-fifths wider than long, all the angles well rounded; apex distinctly sinuate as in the AppITIONS TO NoRTH AMERICAN COLEOPTERA Li preceding; surface smooth, with the usual few faint rugule, but not at all im- pressed; inner fovea linear, feebly impressed, with vestiges of feeble punctures; elytra three-sevenths longer than wide, with broadly arcuate sides, barely per- ceptibly wider than the prothorax, more gradually and less obtusely rounded behind than in modulatus; striez not so fine and with less flattened intervals. Length (9) 7.6-8.0 mm.; width 3.0-3.15 mm. Michigan (Marquette),— Sherman. Five specimens, all females, the male not at hand. Differs from modulatus in its more elongate form, less transverse prothorax, more gradually rounding elytral apex, the elytra not distinctly wider than the prothorax. Neither of these species has accessory abdominal sete. Of appositus, described from Siskiyou Co., Calif., I now have an identically similar specimen from Wawawai, Washington State. The following species may be placed just after renoicus: Harpalus subenormis n. sp.—Elongate-suboval, unusually convex, polished, deep black throughout, the legs black; head moderately small, three-fifths as wide as the prothorax, the moderate eyes rather strongly convex; anterior strioles short and punctiform, deep; mandibles and palpi black; antennz a little longer than the thoracic width, piceous-black, obscure testaceous basally, compressed, the medial joints fully one-half longer than wide on the flattened sides; prothorax barely more than a third wider than long, the sides broadly arcuate and converging apically, nearly straight and parallel basally, the angle right, with narrowly rounded apex and no puncture; surface convex, smooth, very finely subrugulose basally, but not punctate, the narrow linear impression at outer fifth almost obsolete; median line very fine and feeble, not extending beyond two-thirds; elytra nearly one-half longer than wide, at the middle of the arcuate parallel sides about a fifth wider than the prothorax; posterior sinus short and feeble; striae moderate, rather conspicuous, smooth, coarser at apex; intervals just visibly convex, the third with a small puncture at four-fifths. Length (2?) 8.2 mm.; width 3.35 mm. Utah (Callao),—Spalding. A distinct species, somewhat allied to renoicus, but with the prothorax more narrowed apically and less transverse, the body narrower and still more convex and the head evidently though but slightly larger. The following species has been received recently and is sufficiently distinct as a species to be described: Harpalus provensis n. sp.—Oblong, rather broad, black, the tibia and tarsi rufo-piceous; head only four-sevenths as wide as the prothorax, rather wider than long, the anterior impressions small and punctiform; eyes but moderately prominent; antennz obscure rufous, thick, slightly attenuate basally and apically, the third joint distinctly shorter than the fourth; prothorax but little over a third wider than long, the parallel sides rather feebly arcuate, more rounding apically; base transverse, much wider than the moderately sinuate apex; all angles well rounded; fine incised basal margin subobsolete medially; side margins very narrowly reflexed and feebly pallescent; surface nearly smooth, only very faintly impressed at any part, the incised median line fine, abbreviated apically and more briefly at base; scutellum triangular, much wider than long; elytra 114 MEMOIRS ON THE COLEOPTERA barely two-fifths longer than wide, oblong, with somewhat arcuate sides, slightly wider than the prothorax; striz fine, smooth, feebly impressed, the scutellar fine, proceeding from a distinct puncture; tarsi slender. Length (9) 10.4 mm.; width 4.1mm. Utah (North Fork, Provo Cafion),—Spalding. Allied somewhat to uteanus but, comparing the females, having an evidently smaller head, less prominent eyes and more elongate prothorax, with more broadly rounded angles; the upper surface is feebly shining, with opaque elytra. A specimen of blanditus Csy., was taken by Prof. Piper at Priest Lake, Idaho. The three following species are allied more or less closely to spadiceus De}.: Harpalus beatulus n. sp.—Parallel, convex, black, polished; under surface black, with paler margins, the legs yellowish-red; head large, nearly three-fourths as wide as the prothorax, the eyes well developed, moderately prominent; an- tenne testaceous, compressed, scarcely one-half longer than the prothorax, the latter long, only between a fourth and third wider than long, the sides distinctly but broadly arcuate, becoming straight—then feebly sinuate—behind, the angles right and rather sharply defined; surface smooth, the stria deeply impressed, entire; latero-basal region with fine sparse punctures, stronger and denser in the inner fovea, the latter linear but broadly, deeply impressed; side margins very finely reflexed throughout, feebly rufescent; elytra two-fifths longer than wide, subequal in width to the prothorax and not quite twice as long, rapidly rounding at apex, with feebly arcuate sides; strie# notably coarse and deep, not stronger distad; intervals broadly but distinctly convex; first male tarsi very moderately dilated, the second feebly so. Length (co) 8.6 mm.; width 3.2 mm. Michigan (Marquette),—Sherman. One example. Differs from spadiceus in its shorter antenne and much less oblique posterior sides of the prothorax. Harpalus indigens n. sp.—Much smaller, parallel, convex and shining, the under surface similar, the legs pale testaceous; head nearly as in the preceding; antenne slender, testaceous, not quite as long as the head and prothorax, the latter shorter, about two-fifths wider than long, widest well beyond the middle, the sides distinctly rounded, feebly oblique and perfectly straight in basal half, the margins finely reflexed and slightly diaphanous, the basal angles right and well defined, not more than very narrowly blunt at tip; surface with vestiges of broad and diffuse transverse impressions medially, the latero-basal region with minute feeble sparse punctures, the fovea long, linear, narrow and rather deep; elytra about as wide as the prothorax, parallel, with feebly arcuate sides and obtuse apex, nearly one-half longer than wide; strie strong and deep; intervals feebly convex; first male tarsi rather feebly dilated, the second a little less so. Length (@) 7.2 mm.; width 2.6 mm. Maine (Monmouth),—Frost. One specimen. Allied to the preceding and differing from spadiceus in its much less oblique sides of the prothorax posteriorly; it is very much smaller than either. ADDITIONS TO NORTH AMERICAN COLEOPTERA 115 Harpalus electus n. sp.—Broader, parallel, rather strongly convex, shining, _ black, the under surface black, with the margins dark rufous, the legs rufous; head relatively much smaller than in the preceding two or spadiceus, only four- sevenths as wide as the prothorax, with rather prominent eyes; entire apical parts and mandibles rufescent; antenne slender, testaceous, barely one-half longer than the prothorax, the latter large, only between a fourth and third wider than long, widest well beyond the middle, the sides distinctly arcuate, becoming straight to very feebly sinuate in basal half; angles more than right and somewhat bluntly rounded; surface scarcely at all impressed, but with fine longitudinal rugule at apex and base, the latero-basal region impunctate, smooth, the fovea linear, but feebly impressed and shallow; stria extremely fine; elytra oblong, only two-fifths longer than wide, barely more than twice as long as the prothorax, equal in width to the latter, with feebly arcuate sides and rapidly obtusely rounded apex; strie moderately strong, gradually a little coarser posteriad; intervals broadly and feebly convex, barely at all alutaceous in the female. Length (2) g.0 mm.; width 3.6mm. Canada (Edmonton, Alberta). One specimen. A remarkable species, of broad oblong form and wholly unlike any other; it may be placed in the spadiceus section, however. There are apparently no accessory sete in any of the spadiceus section. The small species in the neighborhood of herbivagus Say, are not very well understood; herbivagus is the largest of the section, and my large series shows that it is distributed from Maine and North Carolina westward to Colorado. Pluriticus Kirby, is smaller and shorter, black or blackish, with pale reflexed margins, pale brown elytra and yellowish legs; it extends from Maine to Edmon- ton, Alberta. Lividulus Csy., has been referred to above, it is slightly larger and more elongate than pluriticus, with rather smaller head and is black, with pale legs, the elytra sometimes feebly picescent; it occurs from Virginia to Lake Superior and New Mexico. Blanditus (ante), from the Pacific coast of British Columbia, is smaller and more ventricose, and nivalis (ante) more elongate, with somewhat larger head; it occurs in Saskatchewan. Finally, of this more immediate section, we have foveicollis Lec., which seems to by confined to the extreme eastern provinces and is still represented in my collection by a single example from New Brunswick; it is relatively still narrower than nivalis and has a less transverse prothorax; it differs from the others also in having the sides of the prothorax in basal half more oblique and in having the deep foveiform impression near each side of the thoracic base demarcated externally by a narrow smooth longitudinal ridge at some distance from the side margin; it is a remarkably distinct species and apparently rare. 116 MEMOIRS ON THE COLEOPTERA Euharpalops n. gen. This genus is related rather closely to Harpalus, but is more ventricose in outline and differs in the anterior male tarsi, which have beneath on each joint an acutely, anteriorly angulate chevron, which has none of the transverse strigilation seen in normal Har- palus, but is perfectly flat, uniform in texture and only very briefly pubescent; the type is as follows: Euharpalops wadei n. sp.—Oblong, moderately convex, polished, the female elytra dull; color obscure rufous, the elytra black, less so in the female; legs piceous; head rather large, nearly two-thirds as wide as the prothorax, the eyes moderate, not very strongly convex; anterior strioles short, coarse, lying within feeble concavities; mandibles strong; antenne obscure testaceous, not extending quite to the thoracic base, only feebly compressed, the third joint slightly longer than the fourth, the second more than twice as long as wide; prothorax about four-sevenths wider than long, the sides feebly arcuate, rather straighter in about basal half, slightly widest a little beyond the middle; base rectilinearly transverse, with slightly obtuse but scarcely blunt angles, a fourth wider than the distinctly sinuate apex, the latter having short and moderately rounded angles; surface smooth, with very feeble ruguliform lines, closely and rather finely punctato- rugose latero-basally, the basal impression, near outer fourth, very shallow; median line very fine, abbreviated; anterior transverse impression obsolete; elytra oblong, with parallel and broadly arcuate sides and gradually broadly rounded apex, the latter having just visible sinuosity, three-sevenths ( @ ) to four- sevenths (o”) longer than wide, two-fifths (<) to nearly one-half (2) wider than the prothorax; striz smooth, strong (<7), finerand feebler ( 2); intervals perfectly flat in both sexes, the third having a puncture near the second stria, at a little beyond two-thirds; scutellar stria long, free or not; first four anterior male tarsal joints well dilated. Length (o@ 9) 14.5 mm.; width 6.0-6.2 mm. Oregon (Moro),—J. S. Wade. This species is obviously very close to Harpalus, and may be regarded as only subgeneric, but the under surface of the anterior male tarsi is notably different. The abdomen, just behind each coxa, is finely and closely punctured in a limited area having short fine inconspicuous pubescence. Pteropalus Csy. In vulpeculus Say, the head and prothorax are distinctly smaller, when compared with the width of the elytra, than in the other three described species. The following is a subparallel species, allied to dichrous Dej., but smaller and notably narrower: — Pteropalus versutulus n. sp.—Polished, testaceous, the elytra black, with strong iridescence; head about three-fourths as wide as the prothorax, the eyes well developed but only moderately prominent; apical strioles extremely small and shallow; antennz slender, testaceous, slightly compressed, the medial joints nearly three times as long as wide on the flattened sides; mandibles strongly arcuate distally; prothorax two-fifths wider than long, slightly more (@), the AppITIONS TO NortH AMERICAN COLEOPTERA 117 parallel sides subevenly and distinctly arcuate; basal angles obtuse, evidently rounded; surface smooth, shallowly bi-impressed basally at each side, the anterior transverse impression distinct and angulate; median line fine; sides basally feebly subdeplanate; elytra two-thirds (<”) to one-half (9) longer than wide, at the middle of the feebly arcuate sides only a sixth or seventh wider than the prothorax; apex gradually and unevenly rounded, the sinus extremely feeble; striz strong, deep, smooth, the second with a distinct puncture at three-fifths; intervals rather strongly (co) or feebly (2) convex, not differing sexually in the polished lustre; anterior male tarsi moderately dilated, the intermediate undilated, slender. Length (7 @) 9.0-9.8 mm.; width 3.25-3.6 mm. North Carolina (Southern Pines),—Manee. Differs from dichrous in its smaller size, narrower outline, more acute elytral apices and more nearly obsolete sinus. The female seems to be a little smaller and more abbreviated than the male. Hemisopalus Csy. This and the preceding group are now considered as subgenera, but for the present purposes, at least, they and Celiamorphus may be regarded as genera. Hemisopalus trepidus n. sp.—Elongate-suboval, notably convex, polished, black, the under surface piceous, the legs paler, rufous; upper surface greenish- metallic; head rather large, fully three-fourths as wide as the prothorax; eyes well developed but not very prominent; apical strioles subobsolete; antenne somewhat slender, testaceous, the medial joints between two and three times as long as wide; prothorax nearly one-half wider than long, the parallel sides evenly and distinctly arcuate, the finely reflexed edges piceous; basal angles obtuse and rounded; surface smooth, the anterior and posterior impressions evident but feeble; base with a large shallow smooth impression at each side; elytra three- fifths longer than wide, gradually rounding behind, barely at all wider than the prothorax, the parallel sides not quite straight; striae very moderate; serial punctures of 2-5-7 very small; scutellar stria very short, nearly obsolete; inter- vals flat. Length (9) 8.15 mm.; width 2.9 mm. Florida (Cape Sable),— W.S. Blatchley. A single specimen. At first I regarded this as an extreme form of gagatinus Dej., but it seems different on more careful study, being larger, with flatter strial intervals, finer and feebler strial series and more nearly obsolete scutellar stria. Celiamorphus Csy. The following species is broader and more opaque than either fossulatus or ellipticus: Celiamorphus municeps n. sp.—Oblong-suboval, rather notably convex, black and opaculate, especially the elytra; under surface and legs piceo-rufous; head half as wide as the prothorax, the eyes moderate, not notably prominent, the apical strioles obsolete; antenne slender, piceous, the medial joints more than twice as long as wide; prothorax slightly less than one-half wider than long, 118 MEMOIRS ON THE COLEOPTERA the sides feebly converging and broadly arcuate anteriad, straighter and parallel basally; basal angles nearly right and well defined; surface somewhat shining, broadly opaculate at base toward the sides and feebly, longitudinally impressed near outer fourth; surface smooth, the impressions obsolete, the median line fine; scutellum much more shining than the elytra, which are three-sevenths longer than wide, with parallel and almost straight sides and broadly obtuse apex, equal in width to the prothorax; stri@ rather fine; punctures of 2-5-7 very small and feeble, sometimes more distinct 6n 2; scutellar stria very short and fine, proceeding from a rather large post-basal puncture. Length 5.4 mm.; width 2.3mm. North Carolina (Southern Pines)—Manee. Two specimens. Differs very much from fossulatus in its opaque surface and fine tri-serial punctures, and, from ellipticus, in its stouter form, but less abbreviated prothorax and less shining surface; it is smaller and much shorter than opaculus and with smaller head. Celiamorphus subtropicus n. sp.—Elongate, parallel, piceous, feebly shining, the elytra opaque, at least in the female, the legs rufous; head well developed, three-fifths as wide as the prothorax, the eyes large, moderately prominent; antenne very slender, fuscous, a little paler basally; prothorax not quite one- half wider than long, the sides broadly, feebly arcuate, a little more so and evi- dently converging beyond the middle, the angles slightly more than right, rather distinct; surface almost smooth, slightly uneven, not explanate at the sides; elytra three-sevenths longer than wide, as wide as the prothorax, the sides parallel and nearly straight, the apex obtusely rounded; apical sinuses short, evident; strie fine, the three series of punctures distinct, the scutellar stria moderate, oblique; intervals flat. Length (@ 9) 5.2-5.9 mm.; width 2.2-2.4mm. Texas and northern Mexico. Five specimens. Differs from ellipticus in its more elongate-parallel outline and piceous coloration; the entire upper surface is shining but not highly polished in the male. Celiamorphus nanulus n. sp.—Small, rather narrow, convex, deep black and polished throughout in the male, the legs dark piceous; head very moderate, the eyes not very prominent; antenne very slender, fuscous, gradually testaceous basally; prothorax two-fifths wider than long, the sides broadly arcuate, con- verging anteriorly, less arcuate and parallel basally, the basal angles right and only slightly blunt; surface nearly smooth, steep and abruptly horizontally deplanate at the sides, more broadly behind, but not attaining the base; median line only evident centrally; elytra three-sevenths longer than wide, as wide as the prothorax, parallel and nearly straight at the sides, broadly subcircularly rounded at apex, the sinuses extremely shallow; stria# smooth, not very fine, distinctly impressed, coarser and exarate on the apical declivity; punctures of the three series rather small but impressed and distinct; scutellar stria very short and extremely fine, oblique, the puncture coarse and deep. Length (@) 4.4-4.6 mm.; width 1.8 mm. North Carolina (Southern Pines),—Manee. Two specimens. Easily distinguishable from the male of ellipticus by its smaller size, much narrower outline, smaller head and especially by the stronger, impressed and much more conspicuous elytral striae. ADDITIONS TO NORTH AMERICAN COLEOPTERA 119 This species is the fifth described from the regions about Southern Pines, a rather singular fact, although a thorough search of other parts of the southern States might reveal many species still un- described. There is reason to believe that the species described from Southern Pines are all truly valid. I regret being unable to examine the original types of ellipticus, pulicarius and granarius Dej., for it is more than possible that they are valid species. Discoderus Lec. This relative of Selenophorus is evidently very widely distributed and is represented by numerous species, all of which can be recog- nized at once by a peculiar habitus; they are elongate, parallel- suboval and of very marked convexity. The following is allied closely to zmpotens Lec., but is not so large, narrower in form and with much shorter scutellar stria: Discoderus papagonis n. sp.—Polished black, with feeble subzneo-metallic lustre, the under surface blackish-piceous, the legs piceous; head well developed, with prominent eyes, fully two-thirds as wide as the prothorax, the punctiform anterior strioles rather coarse and deep; antennz piceous, slender and only feebly subcompressed, the medial joints almost three times as long as wide; prothorax rather short, almost one-half wider than long, the parallel sides evenly and distinctly arcuate, the basal angles broadly rounded; surface smooth, feebly impressed at outer fourth near basal fifth, the sides narrowly subdeplanate basally; anterior transverse impression evident; elytra a little more than one-half longer than wide, parallel, with feebly arcuate sides, only very slightly wider than the prothorax; strie smooth, very moderate, coarser distally, 2-5-7 with moderate punctures, the intervals very feebly convex. Length (@ @) 7.1-7.3 mm.; width 2.7-2.8 mm. Arizona (locality unrecorded) and New Mexico (Alamogordo). The prothorax is less transverse than in tmpotens and with less strongly arcuate sides, and the hind tarsi are shorter and more slender—among other differences. The Alamogordo specimen is a female, but does not differ materially from the male, except in its nearly straight middle tibiz. The following may be placed in the same section as impotens, but has a larger and less abbreviated prothorax: Discoderus texanus n. sp.—Oblong, convex, polished, the coloration nearly as in the preceding, the legs more nearly black, the thoracic marginal bead similarly obscurely testaceous but thicker; head nearly similar and rather well developed, about three-fifths as wide as the prothorax; antenne dark testaceous, extending to the thoracic base, slightly compressed, the medial joints two and one-half times as long as wide on the flattened side; prothorax large, about a third wider than long, the parallel sides evenly and moderately arcuate, the basal angles broadly rounded; surface smooth, the transverse impressions nearly obsolete, rather abruptly and broadly deplanate in less than basal third and thence very narrowly concave along the sides; basal impression at outer fourth narrow, 120 : MEMOIRS ON THE .COLEOPTERA linear and very feeble; elytra barely one-half longer than wide, parallel, barely perceptibly wider than the prothorax, the sides at apex oblique but with the sinus scarcely traceable; striae smooth, moderate, somewhat coarse apically, 2-5-7 with small but very distinct punctures, the scutellar stria long; intervals feebly convex; anterior male tarsi as usual, undilated and nude beneath. Length (7 2) 8.5-8.7 mm.; width 3.25-3.4 mm. Texas (Dallas). Two examples. Notably larger than zmpotens and with larger and much less abbreviated prothorax, the surface lustre less eaneous. The de- planate thoracic surface near the hind angles is remotely and very obsoletely punctulate. Discoderus dallasensis n. sp.—Oblong, convex, polished, black, with subeneous lustre above, blackish beneath, with piceo-rufous legs; head well developed, fully three-fifths as wide as the prothorax, with rather prominent eyes and two coarse deep apical punctures; antenne slender, testaceous, only very feebly compressed, the medial joints not quite three times as long as wide; prothorax a little less than one-half wider than long, the parallel sides evenly and moderately arcuate, with obscure testaceous bead, the hind angles broadly rounded; surface smooth, with shallow but obvious transverse impressions, subdeplanate along the broad basal angles, the impression at outer fourth diffuse and subobsolete; a few punctures are usually visible along the sides basally; elytra one-half longer than wide to less, parallel, but very slightly wider than the prothorax, the smooth striae rather strong, impressed, coarsely exarate apically, the punctures of the three series feeble or inconspicuous; scutellar stria moderate; intervals slightly convex. Length (o@ 2) 7.4-8.7 mm.; width 2.8-3.35 mm. Texas (Dallas and Amarillo). Eight specimens. The species in this part of the genus are rather closely allied among themselves. In fexanus the prothorax is notably large; in @qualis and symbolicus the elytra are more evidently elongate, and, in the former, the head is notably large; in dallasensis the elytra and prothorax are both more abbreviated, with the head not quite so developed as in @gualis, but more so than in fexanus. The following species is somewhat closely allied to the smaller and narrower congruens, but differs in its larger head and longer mandibles: Discoderus peregrinus n. sp.—Rather narrow, parallel and strongly convex, polished, not metallic, piceous-black, the under surface and legs obscure testa- ceous; head nearly two-thirds as wide as the prothorax, somewhat longer than wide, the mandibles longer than the space from the anterior margin of the eyes to the base, the eyes rather prominent; two apical punctures deep; antenne and labrum testaceous, the former slender, barely at all compressed; prothorax two-fifths wider than long, the parallel sides evenly and distinctly arcuate, the basal angles broadly rounded; surface smooth, very convex, rapidly declivous at the sides, narrowly deplanate, with a few punctures along the basal angles, having some transverse ruge medially, the impression at lateral fourth of the base feeble, the transverse impressions subobsolete; elytra fully one-half longer than wide, barely visibly wider than the prothorax; striae smooth, very deeply impressed, subcontiguous, coarser and exarate on the declivity, the scutellar stria ApDITIONS TO NORTH AMERICAN COLEOPTERA 121 rather short, disintegrated; punctures of the three series small and feeble; inter- vals notably convex; hind tarsi more slender than usual. Length (7) 8.0 mm.; width 2.9 mm. Texas (El Paso). This is a rather distinct species, differing from congruens in its more prominent eyes and longer mandibles, among other characters. The two following small species are members of the farallelus and hesperius section: Discoderus parvuliceps n. sp.—Parallel, black or faintly piceous, shining, black beneath, the legs obscure rufous, with black femora; head small, scarcely more than half as wide as the prothorax, with prominent eyes and short narrow apical strioles; antenne testaceous, slender; prothorax long, between a fourth and third wider than long, the sides broadly arcuate, more so and strongly con- verging apically, more parallel basally; apex but slightly over two-thirds as wide as the base, with narrowly rounded apical angles; basal angles well rounded; side margins very finely reflexed; base broadly sinuate medially; surface smooth, the transverse impressions and fine median line almost obsolete, feebly sub- deplanate along the angles, the impression near outer fourth at base distinct and somewhat oblique; elytra one-half longer than wide, parallel, circularly rounded behind, barely at all wider than the prothorax, the subapical sinus virtually obsolete; strie rather fine, impressed, coarser on the declivity, the scutellar well developed; punctures of the three series small and widely separated; intervals only feebly convex. Length (co) 6.8 mm.; width 2.8 mm. Colorado (Wray), —Shantz. Differs from parallelus in the slightly longer and still more apically narrowed prothorax, with more distinct basal impressions and in the more elongate elytra. Discoderus gener n. sp.—Narrower and more elongate, convex, polished and rather deeper black, the legs almost similar; head not quite so small, very slightly more than half as wide as the prothorax, the eyes evidently less prominent, the apical strioles feeble and very minute; antenne somewhat fusco-testaceous, slender; prothorax a fourth (o*) or a third (9) wider than long, nearly as in the preceding but not quite so narrowed at apex, the transverse impressions more evident, the impression at lateral fourth deep, more separated from the base; elytra rather more than one-half longer than wide, a very little shorter in the female, subequal in width to the prothorax, the apices, striation and intervals nearly similar. Length (@ @) 7.1-7.25 mm.; width 2.7-2.8 mm. Washington State (Wawawai). Two specimens. Narrower and more elongate than parallelus and even a little more so than parvuliceps; they both, as well as parallelus, have the prothorax much more elongate than in hesperius and the size of the body not quite so small. The specimens of the ample series of parallelus in my collection were taken from the Atlantic coast to Iowa and Missouri, and the still larger series of hesperius at various localities in Texas, Kansas and Colorado. 122 MEMOIRS ON THE COLEOPTERA Stenomorphus De}. This is one of the more isolated Harpalid genera, not only in general habitus but in some of its special structural characters. The two following species seem to be undescribed: Stenomorphus parallelus n. sp.—Shining, piceo-castaneous, the under surface and legs dark rufous; head moderate, longer than wide, two-thirds as wide as the prothorax, the neck long and the eyes prominent; anterior impressions large and deep; antenne ferruginous, compressed, the medial joints two and one-half times as long as wide on the flattened side; prothorax not quite a third longer than wide, the sides subparallel, arcuate, more convergent and faintly subsinuate in about basal third, all the angles broadly rounded; surface smooth, with distinct transverse ruge medially, without transverse impressions but with a large deep elongate-oval impression at each side near the base, the bottom of the impression more deeply lineate; median line fine and entire; base feebly sinuate, two-thirds the maximum width; elytra parallel, two-thirds longer than wide and three-fourths longer than the prothorax, only just visibly wider than the latter, the striz rather coarse, deeply impressed, very coarse on the apical slope, the sinuses long and shallow; scutellar stria well developed. Length (2) 10.7 mm.; width 3.0mm. Kansas (McPherson),—Knaus. Differs from the female of scolopax in its rather broader and more abbreviated outline, relatively somewhat smaller and shorter head, broader and less elongate prothorax, with more arcuate sides and relatively shorter elytra, which are barely wider than the prothorax and not much wider than that part as they are in scolopax. Stenomorphus arcuatus n. sp.—More slender in form, shining, piceous; head rather small, though two-thirds as wide as the narrower prothorax, with prominent eyes and two moderate apical fovee; antenne long, testaceous, only feebly compressed, the medial joints almost three times as long as wide on the broader face; prothorax narrow, nearly one-half longer than wide, the sides subparallel, broadly arcuate, more converging and faintly sinuate basally, all the angles moderately rounded; surface only faintly, transversely rugulose, the anterior transverse impression evident, the lateral fovee long, narrow, deep, almost extending to the base and near lateral fifth; base truncate, four-sevenths the maximum width; elytra parallel, fully three-fourths longer than wide, three-fifths longer than the prothorax and almost a third wider; strie rather deep but with almost flat intervals, rapidly exarate on the apical slope. Length (2) 10.7 mm.; width 2.85 mm. Texas (Dallas). One example. Differs from the other two species here mentioned in its more slender form and especially in the outline of the prothorax, which is here narrower and more elongate and with the sides arcuate in such a way that the widest section is just beyond the middle and not near the apex; the head also is evidently smaller. Anisodactylus Dej. A considerable number of undescribed species have come to light in this genus, of which the following may be made known at the present time: ApbpDITIONS TO NORTH AMERICAN COLEOPTERA 123 Anisodactylus tioganus n. sp.—Oblong, rather narrow, convex and shining, deep black throughout the body and legs, the antenne pale at base; head as in nigerrimus, but relatively a little larger, the eyes even less prominent; prothorax as in that species but with the basal impressions shallower and not quite so lateral, being somewhat within lateral fourth and with the lateral parts of the basal region finely, densely and conspicuously punctate; narrow lateral deplan- ature punctulate, becoming obsolete only very near the apex; elytra distinctly more than one-half longer than wide, only very slightly wider than the prothorax; strie moderate, not deeply impressed, the second with an adherent puncture just behind apical third; intervals nearly flat even in the male; scutellar stria well developed; apical sinuses very shallow; anterior male tarsi distinctly dilated, obscurely rufescent. Length (@) 10.0 mm.; width 3.65 mm. Pennsylvania (Tioga Co.). Evidently allied to nigerrimus Dej., but a little smaller and much narrower, with much more conspicuous latero-basal thoracic sculp- ture and more elongate and less highly polished elytra, having the strial intervals decidedly less convex; the prothorax is shorter. It is possible that such species as furvus, harrist, the two here mentioned and the following, all having rather broadly rounded thoracic angles, could be transferred to Xestonotus, although there would be considerable diversity of habitus. Anisodactylus lacertosus n. sp.—Oblong, rather convex, deep black, polished, the elytra feebly alutaceous in the female; legs black, the anterior tarsi piceo- rufous; head moderate, scarcely three-fifths as wide as the prothorax, the middle of the front with a feeble transverse red spot; apical strioles short and narrow, deep; eyes rather convex; antenne fusco-testaceous, the first joint paler, rufous, the medial joints feebly compressed, a little more than twice as long as wide; prothorax only two-fifths wider than long, the parallel sides broadly and evenly arcuate, with moderate black reflexed edges, the basal angles broadly rounded; surface smooth, with a few feeble transverse rugule, broadly densely punctate basally, except at the middle and thence anteriorly along the abruptly explanate sides, extending to the apex, the longitudinal basal impression at outer fourth shallow; transverse impressions broad, shallow and obtuse; elytra three-fifths longer than wide, at the middle of the parallel and feebly arcuate sides barely visibly wider than the prothorax: stria sharp, smooth, distinctly impressed, not much coarser apically, the puncture adhering to the second at three-fifths, the scutellar stria unusually long and deep; intervals distinctly convex, flatter apically. Length (2) 13.0 mm.; width 4.9 mm. A single specimen, probably taken by Levette in Indiana. This species is very distinct and is allied somewhat to harrisi, but is larger, more elongate and with flatter strial intervals apically; ' the prothorax is even less transverse than in that species. In interpunctatus Kirby, of which I now have an authentic example from Lake Superior—those which I previously identified under this name being merely nigritus Dej—the body is a little shorter and more ventricose and the head smaller and with less prominent eyes than in nigritus. The confused punctulation of the 124 MeEmorrRs ON THE COLEOPTERA strial intervals is generally discoverable; it is very feeble in nigritus but, in znterpunctatus becomes closer and more conspicuous. Anisodactylus aleneanus n. sp.—Elongate, moderately convex, black through- out, shining, the elytra rather less so; head nearly two-thirds as wide as the prothorax, the eyes moderately prominent, the apical strioles narrow, slightly oblique; front with a feeble nubilous central transverse spot; antennz fusco- testaceous, rather long, only very moderately compressed; prothorax only a little over a third wider than long, the sides feebly inflated and rounded, becoming slightly convergent and feebly sinuate behind about the middle, the basal angles scarcely more than right and well defined; surface nearly smooth, closely, strongly punctate and feebly impressed sublaterally at base, convex and less punctate thence to the rather narrowly, subequally reflexed and punctulate sides; trans- verse impressions distinct, the median line deeply impressed; elytra parallel, with feebly arcuate sides, three-fifths longer than wide, barely a fifth wider than the prothorax; striz sharply defined but not distinctly impressed, the intervals nearly flat; puncture of the second stria near three-fifths; scutellar stria deep and well developed, widely free; anterior male tarsi rather widely dilated but virtually black. Length (co) 11.0mm.; width 4.2mm. Idaho (Cceur d'Alene), —Wickham. Allied only to oregonus, but differs in its larger size and more elongate outline, also in the slightly more elongate antenne; the apical sinuses of the elytra are deeper. The following is also allied to oregonus, but differs in its more abbreviated form and in its relatively larger and more transverse prothorax: Anisodactylus comes n. sp.—Oblong, subparallel, deep black and moderately shining, not so polished as in oregonus; head as in that species and with only moderately prominent eyes, also with the large, deep and irregular apical impres- sions of that species; antenne shorter, fuscous, rather strongly compressed, the medial joints not quite twice as long as wide on the flattened side; prothorax relatively larger, nearly one-half wider than long, the surface similarly moderately reflexed along the sides, the basal impressions strongly, closely punctate; basal angles nearly right, rathersharp, the sides before them oblique and almost straight; transverse impressions feebler, the median line finer and less impressed; elytra oblong, but just visibly wider than the prothorax, the strie sharp but moderate, only feebly impressed, the puncture at three-fifths feeble, the scutellar stria less impressed and not so free; intervals (Q) only feebly convex. Length (92) g.5-10.5 mm.; width 3.8-4.0mm. California (Humboldt Co., Valley of Redwood Creek). Two specimens. Besides its larger and broader prothorax, this species differs from oregonus in having the anterior tarsi of the female darker, shorter and relatively broader than in the same sex of that species, where they are rather bright rufous. Anisodactylus mestus n. sp.—Oblong, moderately convex, not very shining, the elytra opaque ( 2), deep black, the legs wholly black; head rather more than two-thirds as wide as the prothorax, but with not very convex eyes, the apical strioles slightly oblique, each ending posteriorly in an irregular transverse im- ADDITIONS TO NORTH AMERICAN COLEOPTERA 125 pression; central nubilous red spot very faint; antenne piceous-black, with obscurely rufous basal joint, thick and but feebly compressed; prothorax two- fifths wider than long, subinflated and with arcuate sides, which become oblique and straight posteriad, the angles slightly more than right but sharply defined; surface rugulosely and feebly punctate in the shallow transverse anterior, and large shallow posterior, impressions, the latter separated from the sides by less punctate elevation; feebly reflexed margins not extending to the base; median line distinct; elytra one-half longer than wide, with parallel and broadly arcuate sides and about a third wider than the prothorax; strie# distinctly impressed basally, thence throughout and externally fine and rather feeble, with perfectly flat intervals, the third with a small puncture at four-sevenths, remote from the second stria; scutellar stria long and deep, free; third and fourth striz unevenly interrupted just before the middle in the type. Length (9) 10.8 mm.; width 4.0mm. California (Sta. Cruz). Allied in some respects to obsolescens, but with the eyes somewhat less prominent, the anterior thoracic impression distinct and strongly punctured, the basal part of the elytral striae more impressed and the apical sinuses deeper; the elytral humeri are much more exposed basally, as in humeralis, from Reno, Nevada, but in the latter species the pronotum is differently and very much less punctured. Anisodactylus (Aplocentrus) viridans n. sp.—Oblong-suboval, rather convex, moderately shining, black, with pronounced greenish lustre above, deep black beneath, the legs obscure rufous, with black femora; head barely more than half as wide as the prothorax, with rather prominent eyes, the anterior strioles narrow, oblique, rather long and uneven; antenne slender, blackish, with the first three joints testaceous; medial joints fully three times as long as wide; prothorax barely more than a third wider than long, the sides broadly arcuate and converging anteriad, parallel and nearly straight behind about the middle, the marginal bead testaceous; basal angles right, with the apices minutely blunt; surface smooth, finely punctured latero-basally, deplanate laterally and with a feeble impression at about lateral third and basal fourth; transverse impressions very feeble; elytra four-sevenths longer than wide, parallel, with feebly arcuate sides, very slightly wider than the prothorax; strie sharp and rather strong, the second with a puncture adhering externally at four-sevenths; scutellar stria long and free; intervals flat. Length (%) 8.0 mm.; width 3.35 mm. Kansas (Mc- Pherson),—Knaus. When compared with the male of cwnus this species can be seen to be notably narrower in outline, with relatively less transverse prothorax and with the pronotum in general nearly smooth and not loosely subrugose as it is in that species; the coloration also differs, although this is less important. Triplectrus Lec. The species of this genus in some parts of the series become closely allied and rather difficult to separate, unless there be a considerable number of specimens. The genus itself is undeniably T. L. Casey, Mem. Col. XI, Mar. 1924.—9 126 MEMOIRS ON THE COLEOPTERA closely allied to Anisodactylus, and in some of the latter the anterior tibial spur is angularly dilated at each side near base. The following species is widely isolated in general appearance, due to the abruptly broad pale deplanate pronotal margins: Triplectrus marginatus n. sp.—Rather broad, oblong, moderately convex and unusually shining throughout; piceous-black, the broad deplanate thoracic margins diaphanously pale testaceous; under surface deep black, the legs dark rufo-piceous; head well developed, though scarcely over half as wide as the broad prothorax, the eyes rather prominent; apical strioles short but deep; antenne black, the first two joints and part of the third testaceous, the medial joints between two and three times as long as wide; prothorax large, transverse, fully one-half wider than long, evenly and moderately narrowed from the narrowly rounded basal angles to the apex and evenly, very moderately arcuate; pallid lateral deplanature almost smooth, gradually narrowing but attaining the apex; surface nowhere evidently punctate, finely, longitudinally rugulose medially at apex and base; transverse impressions barely traceable; base margined in medial half only; elytra very little more than one-half longer than wide, parallel. with feebly arcuate sides, gradually ogival apically, barely as wide as the prothorax; strie smooth, abrupt, deep; intervals 3-5-7 strongly, the others feebly or scarcely convex, 3, 5, 7 with a medial series of distinct punctures from near the middle to near the apex successively, the third with a coarser deep puncture at four-sevenths, near the second stria; scutellar stria long, free; male with the first two tarsi rather strongly dilated. Length (co) 11.0 mm.; width 4.6 mm. Michigan (Grayling—near Bay City),—C. V. Piper. This is one of the more distinct species of the genus and it might take its place at the head of the series of Triplectrus proper; with such species as anthracinus to follow; it does not resemble Gynandro- tarsus. : The species carbonarius of Say, rather common from Long Island to Kansas, as well as the two following species, are distinguished primarily also by rather abruptly deplanate side margins of the pronotum, though in these the flattened margin is not so broad as in marginatus, which species is shorter and broader and with alternating elevation of the strial intervals which is not noticeable here; carbonarius is notably elongate, with densely opaque elytra in the female, more feebly so in the male. , The following species is much shorter and relatively broader than carbonarius: Triplectrus brevior n. sp.—Female oblong, moderately convex, deep black throughout, feebly shining, the elytra densely opaque; head very moderate, a little more than half as wide as the prothorax, the eyes rather prominent, the apical strioles short and subpunctiform; antenne blackish, the first joint obscure testaceous, the medial joints nearly three times as long as wide; prothorax short, fully four-sevenths wider than long, only very little narrowed apically, the sides evenly and rather strongly arcuate; surface broadly impressed and densely punctate latero-basally and thence along the abruptly deplanate sides, which become narrow and concave anteriorly; basal angles blunt and very slightly more than right; transverse impressions obsolete, the median line fine but ADDITIONS TO NORTH AMERICAN COLEOPTERA 127 distinct; elytra one-half longer than wide, slightly though obviously wider than the prothorax, parallel, with feebly arcuate sides, smooth; striae fine, not notably coarser apically: intervals very feebly convex, the third with a small and feeble puncture adjoining the second stria at four-sevenths and another more discal near three-fourths; apical serial punctures extremely few and scarcely obvious; scutellar stria rather long but not coarse. Length (@) 11.2 mm.; width 4.5 mm. Pennsylvania (locality not otherwise recorded). This species is allied to carbonarius, but, besides being much shorter, differs in its notably abbreviated prothorax, somewhat larger head and longer tarsi. The following differs in its notably larger head, more convex surface and very much less abrupt and almost impunctate lateral deplanature of the pronotum; also in coloration: Triplectrus semirubidus n. sp.—Oblong, rather broad, the female somewhat feebly shining, with densely dull elytra, black throughout, excepting the pronotal sides and the entire elytra, which are pale rufo-ferruginous; head large, nearly three-fifths as wide as the prothorax, the eyes very moderate and scarcely at all prominent, the apical strioles short and feeble; antenna missing in the type; prothorax large, about one-half wider than long, narrowed slightly near the apex, the sides subparallel, feebly arcuate, a little more so apically; basal angles nearly right but broadly rounded, a little more broadly than in carbonarius; surface smooth, with large rounded shallow impression near outer fourth of the base, then convex and at the sides rapidly declivous, wholly impunctate latero- basally, except sparsely and very shallowly on the non-abrupt lateral deplanature; margination of the base wanting medially; median line fine, connected with some fine transverse incised lines; elytra only three-sevenths longer than wide, scarcely visibly wider than the prothorax, the parallel sides feebly arcuate; stri# rather strong, only a little coarser apically, the scutellar moderate, oblique; intervals wide, virtually flat; posterior punctures almost as in carbonarius, but very faint. Length (2) 11.3 mm.; width 4.8mm. Illinois (Highland Park, north of Chicago). This distinct species cannot be the same as that named rufipennis by LeConte, as the sides and base of the pronotum are there punc- tate, presumably as in carbonarius, with which it was united as a probable accident of coloration; the head, also, is apparently smaller in rufipennis and the scutellar stria longer and parallel “recta’’; rufipennis was described from the vicinity of New York City. The following may be placed just after haplomus Chd., but is broader and with the thoracic sides much more abruptly and horizontally deplanate: Triplectrus wolcotti n. sp.—Oblong-oval, grayish-black, the thoracic sides feebly and nubilously rufescent; surface dull, the anterior parts more shining; head somewhat wider than long, about three-fifths as wide as the prothorax, with well-developed and moderately prominent eyes and short coarse apical strioles; front without trace of puncture; antennz slender, fuscous, paler at base, not extending to the thoracic base; prothorax three-sevenths wider than 128 MEMOIRS ON THE COLEOPTERA the median length, the sides converging, evenly, moderately arcuate from base to apex; surface smooth, the sides not very broadly but abruptly deplanate and sparsely, feebly punctulate externally, the convexity extending to the angles posteriad, inside of which and just beyond lateral third there is a large smooth oblong impression; angles rather narrowly rounded, somewhat less than right; median line impressed, biabbreviated; transverse impressions wholly wanting; apex rather deeply, evenly sinuate; elytra short, only a third longer than wide, as wide as the prothorax, gradually broadly ogival at apex; striz rather fine but deep and sharp; intervals feebly convex to virtually flat, the alternate ones with a loose series of punctures apically. Length (@) 11.2-11.5 mm.; width 4.8 mm. Northern Illinois (near Chicago),—A. B. Wolcott. Two examples. The basal thoracic angles are much less rounded and more distinct than in haplomus, and the basal impressions much deeper and more conspicuous, besides the differences above noted. The dimensions of my single specimen of haplomus—from St. Louis, Mo.—are 10.6 by 4.45 mm. The following species is small and allied to rusticus Say: Triplectrus oblongus n. sp.—Oblong, parallel, moderately convex, dull in lustre, the elytra more opaque, subsericeous, grayish-black, the under surface and legs deeper black, the pronotum faintly and nubilously rufescent toward the rather narrowly rounded hind angles; head moderate, barely more than half as wide as the prothorax, nearly as in rusticus, the eyes not quite so prominent; antenne piceous, the first two joints testaceous, the median joints about twice as long as wide on the moderately flattened sides; prothorax rather short, three-fifths wider than long, otherwise nearly as in rusticus, except that the median line is more widely biabbreviated; elytra narrower than in that species but otherwise nearly similar, equal in width to the prothorax, the intervals flat; oblique apical sinus a little shorter. Length (2) 9.6 mm.; width 3.8 mm. Pennsylvania (Nisbet). One specimen. When contrasted with a series of about thirty specimens of rusticus in my coliection, extending in range from New England to Colorado and Arizona, the present species is seen to differ in its more abbreviated form and much shorter prothorax, also in its slightly shorter antenne. The hind tarsi in both are long and very slender. The type of @thiops Csy., is represented solely by the single female from Austin, Tex. (Mem. Col., V, p. 175); the two females from Waco, Tex., there placed with the type, constituting as I now find quite a different species, much broader in outline and with notably convex strial intervals, which in @thiops are but slightly convex. The Waco specimens may be described as follows: Triplectrus sulcipennis n. sp—Broadly oblong-suboval, moderately convex, gravish-black, the sides of the pronotum and of the elytra, especially behind, very faintly rufescent; legs dark and obscure rufous throughout; surface rather shining, except laterally, the elytra densely opaque, at least in the female; head four-sevenths as wide as the prothorax, with moderate and rather prominent ApbpITIONS TO NorRTtTH AMERICAN COLEOPTERA 129 eyes, the short apical strioles not linear as in e@thiops but deep, perforate and punctiform, also at an unusually long distance from the apical edge; antenna obscure testaceous, slender, paler at base, a little longer than in @thiops; prothorax large, three-sevenths wider than long, the feebly converging sides evenly and more strongly arcuate, the angles similar; surface similar but with the side margins less strongly reflexed; elytra four-sevenths longer than wide, in outline and relationships nearly similar but broader, the strie similar, not coarse but sharply deep, the intervals much more convex and prominently so along the middle; tarsi long and slender. Length (9) 11.4-12.4 mm.; width 5.0-5.2 mm. Texas (Waco). Two specimens. To be easily known by the broad, oblong-oval form and strongly elevated strial intervals of the elytra; the deep scutellar stria is notably long, parallel and free, as in @thiops; in the latter species the legs are more nearly black. The width of the type of ethiops is scarcely 4.75 mm. The two following species are allied to peropacus, having an opaque surface and strongly convex strial intervals: Triplectrus breviceps n. sp.—Elongate-suboval, moderately convex, deep black throughout, opaque, the anterior parts a little less so; head large, wider than long, four-sevenths as wide as the prothorax, the eyes unusually large but scarcely at all prominent, the anterior strioles short, deep and coarse; antenne slender, blackish, the first two joints testaceous, the medial joints fully three times as long as wide; prothorax large, a little less than one-half wider than long, the sides moderately converging, evenly and moderately arcuate from the narrowly rounded basal angles to the apex; surface smooth, evenly declivous toward the sides, with a narrow feeble linear subbasal impression at each side between fourth and third, wholly impunctate, but throughout with fine remote transverse ruguli- form lines; median line fine, feeble; elytra not quite one-half longer than wide, as wide as the prothorax, gradually ogival at apex, the striz rather fine but deeply impressed; intervals convex, becoming nearly flat posteriad; scutellar stria long, free; tarsi long, slender. Length (2) 19.0mm.; width 5.4mm. Alabama (Mobile),—Léding. Larger than peropacus and more elongate, with larger and more abbreviated head and rather less prominent eyes, the sides of the pronotum not narrowly deplanate as in peropacus, but evenly and convexly sloping throughout to the side margins. Triplectrus longicollis n. sp—Much smaller than in either the preceding or peropacus, oblong, rather convex, parallel, deep black, the anterior male tarsi also deep black, distinctly dilated, the intermediate a little less so; surface opaque; head moderate, barely more than half as wide as the prothorax, as long as wide, the eyes rather prominent; anterior strioles coarse, punctiform, not quite attaining the apical margin; antenne nearly as in the preceding; prothorax large, only two-fifths wider than long, the sides subevenly arcuate and moderately converging from the right and only narrowly blunt basal angles to the apex; surface smooth, as in peropacus throughout, the narrowly deplanate sides similarly being gradually lost basally; reflexed side margins much finer than in peropacus; apical angles similarly well rounded; elytra as wide as the prothorax and not quite twice as long, similarly striate and with the intervals () also distinctly convex through- 130 MEMOIRS ON THE COLEOPTERA out; in breviceps the intervals in the female are much flatter throughout than in the same sex of peropacus; scutellar stria long, strong, tending to unite with the first stria; posterior punctures few in number and as in peropacus. Length (o) 10.3 mm.; width 4.2mm. _ District of Columbia. One specimen. This species is quite distinct from peropacus, though considered with the types of that species in my revision of the genus; it is narrower and very much smaller, and the anterior male tarsi are evidently less strongly dilated. The following species is to be placed near convexus: Triplectrus kempi n. sp.—Oblong, rather strongly convex, slightly shining, the elytra ( 2 ) much more so than in the same sex of convexus, deep black through- out, the hind angles of the prothorax feebly and nubilously rufescent; head rather short, four-sevenths as wide as the prothorax, with the eyes distinctly prominent, the anterior strioles fine and short, much smaller than the concavities of convexus; antenne slender, black, the first two joints piceous; prothorax large, more than one-half wider than the median length, the sides only just visibly converging, broadly and subevenly arcuate from the right and narrowly rounded basal angles to the apex; surface smooth, nowhere punctate, having a few irregular indentations basally, the sides steeply anteriad, gradually more gently posteriad sloping to the fine and but very feebly elevated lateral edges; transverse impres- sions obsolete as usual; median line fine, broadly biabbreviated; elytra evidently less than one-half longer than wide, equal in width to the prothorax, gradually obtusely rounding at the sides behind the middle; striz rather fine, sharply deep, the intervals rather shining, very feebly convex; three punctures of the third small, near, to well behind, the middle and more or less near the second stria; scutellar stria rather short, parallel and widely free. Length (2) 11.8 mm.; width 4.8mm. New York (Lake George),—J. F. Kemp. It is singular that the nearest relative of this species should occur only in the arid regions of Arizona; in convexus the body is stouter, more opaque and the sides of the pronotum slope very steeply to the side margins without trace of the declivous and gradual deplanature of this species. Triplectrus paulus n. sp.—Narrow, parallel-suboval, moderately convex, deep black, feebly shining, the elytra a little more opaque in the female; legs black, the anterior and middle male tarsi piceous-black, moderately dilated; head four-sevenths as wide as the prothorax, barely visibly wider in the female, the eyes rather prominent (<7), less so (9), the apical strioles short, deep and sub- punctiform; antenne slender, fusco-testaceous, clearer at base, the medial joints three times as long as wide, very little less in the female; prothorax a little less (co) or more ( 9 ) than one-half wider than long, the sides nearly parallel and moderately arcuate throughout, the right basal angles rather narrowly rounded; surface smooth, without transverse impressions, rapidly declivous at the sides, somewhat more gradually basally, slightly within outer fourth having a very feeble linear impression at base; elytra nearly one-half (co) or about a third (2) longer than wide, barely visibly wider than the prothorax, distinctly ogival at apex; striae not very coarse but deep, coarser on the declivity, the scutellar rather long, free; intervals very slightly convex, equally so in both sexes, the third with a series of about five small punctures in apical two-fifths. Length (@ 2) 8.7-9.0 mm.; width 3.3-3.7 mm. Texas (Austin). Two specimens. ADDITIONS TO NORTH AMERICAN COLEOPTERA 131 I found the two types of this species mixed with a good series of opaculus Lec., in my collection, but it is very much smaller, with shorter prothorax and deeper elytral striz, more distinctly coarse on the declivity and with more convex intervals, these being virtually flat in the female of opaculus; the head also is evidently smaller. Triplectrus (Gynandrotarsus) beryllus n. sp.—Oblong-oval, strongly convex and polished throughout, black, with feeble greenish-metallic lustre, especially on the elytra, the under surface rufo-piceous, the legs rufous; head four-sevenths (o) to nearly three-fifths (9) as wide as the prothorax, the eyes prominent; apical strioles coarse, deep and irregular excavations; antennz slender, fusco- testaceous, clearer toward base; prothorax a third (c”) to two-fifths (2) wider than long, nearly parallel, with moderately arcuate sides, a little more so apically than basally, all the angles broadly rounded; surface smooth, the transverse impressions vestigial, the elongate shallow basa! impression at outer fourth with a number of distinct punctures; sides very steep, more gradual toward base, the fine beaded margins all testaceous; elytra one-half longer than wide, rather less (2), just visibly wider than the prothorax, with feebly arcuate sides and obtusely ogival apex; striz deeply impressed; intervals convex, less so ( 9 ), flatter apically in both sexes; second stria with a small puncture near apical third, not evident in the male; scutellar stria rather long and deep, free; anterior male tarsi moder- ately, the intermediate feebly, dilated. Length (o@) 9.0-9.3 mm.; width 3.35-3-45 mm. Kansas (McPherson),—Knaus. Three specimens. Differs from harpaloides Laf., in its smaller size, narrower form, less transverse prothorax, with more broadly rounded basal angles, longer antenne and shorter scutellar stria; also some other minor characters. The first joint of the anterior female tarsi is only just perceptibly swollen. I think Gynandrotarsus might just as well be considered a distinct genus. Amphasia Newm. The following is rather closely allied to interstitialis Say, but is apparently different; it is more parallel and less ventricose, with less abbreviated prothorax and more prominent and conspicuous mandibles: Amphasia mollis n. sp.—Parallel, moderately convex, very pale testaceous throughout, except that the elytra are gradually very faintly clouded apically; head four-sevenths as wide as the prothorax, with rather prominent eyes and large, diffusely impressed apical impressions; mandibles large, longer than the distance from their base to the base of the head, pale testaceous, abruptly black at apex; antenne long, slender, testaceous, the medial joints fully three times as long as wide; prothorax a little less than one-half wider than its medial length, parallel, the sides very evenly and rather strongly arcuate; basal angles very broadly rounded; surface feebly impressed and strongly, closely punctured in nearly basal half, sparsely at the middle, also with strong sparse scattered punc- tures apically; impressions obsolete; median line fine, biabbreviated; elytra nearly one-half longer than wide, barely visibly wider than the prothorax; strie coarse, feebly impressed; intervals feebly convex, coarsely and densely punctate, 132 MEMOIRS ON THE COLEOPTERA the scutellar stria coarse, deep and long. Length (2) 10.0mm.; width 3.65 mm. Illinois (Highland Park, north of Chicago). One specimen. Differs considerably from interstitialis, being larger, parallel, less ventricose, with longer elytra having the strial intervals more densely punctate and the apex less obtuse, also in the much less . abbreviated prothorax, with the apical sinus somewhat shallower and in its pale and not blackish elytra; finally in the larger and more conspicuous mandibles, as before stated. Dicheirus Mann. It has proved to be impracticable to clear up the difficulties encountered in my revision of this genus, and the species then unknown to me apparently continue so, but there are nevertheless a considerable number of species received from time to time, which cannot be placed with the known species in my collection, and I therefore venture to describe them. The following three belong to the first section of the genus, having the prothorax more or less inflated anteriorly and strongly narrowed thence to the base: Dicheirus firmus n. sp.—Form somewhat as in dilatatus, but rather more abbreviated and not pale brown but deep black, with the anterior parts rufo- piceous, black or partially rufo-piceous beneath, the legs obscure rufous; head as in dilatatus, the similarly stout antenne dark and very slightly shorter; pro- thorax a little broader, about a third wider than long, coarsely, sparsely and unevenly punctate; base broadly arcuate, the angles very obtuse, moderately rounded; elytra not more than three-sevenths longer than wide, parallel, very obtuse at apex and subequal in width to the prothorax, striate and punctured nearly as in dilatatus, except that the strie are coarser, deeply and abruptly grooved. Length (2) 8.4-8.8 mm.; width 3.35-3.5 mm. California (Alameda and San Francisco). The sparse erect setae throughout are very much as in dilatatus but, besides coloration, firmus differs in having the prothorax obviously less narrowed basally. . Dicheirus multiplex n. sp—Much narrower and more elongate than either dilatatus or firmus, rather bright rufous throughout, except the elytra, which are piceous-black, the sutural interval rufous; surface shining; head rather longer than wide, three-fifths as wide as the prothorax and with moderate but prominent eyes, strongly and sparsely punctate throughout; antenne dark rufous, com- pressed, the medial joints two and one-half times as long as wide on the flattened side; prothorax barely a third wider than long, the inflated sides becoming very oblique and nearly straight basally to the broadly obtuse but sharply defined and unrounded angles; surface strongly and very sparsely punctate, it and the elytra setulose as in the others of this section; elytra long, four-sevenths longer than wide, with parallel and nearly straight sides and rather obtusely rounded apex, very slightly wider than the prothorax, the striz finer than in firmus, abrupt and deep, the intervals perfectly flat, the two series of punctures nearly as in dilatatus but somewhat smaller and less distant. Length (2) 10.0 mm.; width 3.4mm. California (Port Harford, S. Luis Obispo Co.). ADDITIONS TO NORTH AMERICAN COLEOPTERA 133 Recognizable very readily by the notably elongate parallel form, coloration and unrounded though very obtuse basal thoracic angles. Dicheirus beniciensis n. sp.—Elongate, parallel, moderately convex and shining, the elytra duller, rufo-piceous, the legs concolorous, the elytra very slightly darker; pubescence long, erect and rather sparse; head four-sevenths as wide as the prothorax, coarsely and loosely punctate, the eyes prominent; antenne extending well behind the thoracic base, piceous, the third joint much longer than the fourth; prothorax nearly a third wider than long, widest near apical two-fifths, the sides evenly arcuate, becoming strongly oblique and straighter in about basal half, finely reflexed throughout; base distinctly narrower than the moderately sinuate apex, the angles obtuse and rounded; surface coarsely, loosely punctate, more sparsely so transversely at the middle; all impressions obsolete; median stria fine and incomplete; elytra four-sevenths longer than wide, parallel, with nearly straight sides and obtusely rounded apex, without apical sinuses, elytra about as wide as the prothorax to very slightly wider; stria moderate, abrupt, impunc- tate; intervals nearly flat, the two juxta-strial series on each composed of moder- ate, widely and unevenly separated punctures, the scutellar stria free, straight and proceeding from a puncture; anterior male tarsi rather widely, subovally dilated. Length (o 9) 9.8-10.0 mm.; width 3.7-3.8 mm. California (Benicia). Three specimens. Differs from multiplex, to which it is probably most closely related, in its larger size, less slender form, longer antennae, much more prominent eyes and many other features, including coarser serial punctures of the elytra. There are several other varieties in this vicinity that seem to represent distinct taxonomic forms of the genus, hut either so closely allied or represented by so few specimens, that it seems inadvisable to define them. One, represented by a male and female, slightly smaller and somewhat narrower, from an unrecorded locality in California, is nearly like multiplex, but not quite so elongate, with barely perceptibly paler sutural interval and not only very obtuse but broadly, evenly rounded basal thoracic angles and long and heavy antenne—to be recorded as validicornis (n. subsp.)—and another, also like this and multiplex in coloration, but much shorter and broader in outline and with well-rounded basal thoracic angles, the sutural interval not evidently paler; it is labeled Port Harford, but is from a different collector than the type of multiplex and is probably none other than firmus. Dicheirus exiguus n. sp.—Small, narrow, rather convex, shining, sparsely setose, black, the under surface piceous, the legs rufous; head rather small though three-fourths as wide as the prothorax, with moderate and notably prom- inent eyes; punctures deep, rather close laterally, sparse medially; antenne rather thick but long, piceous, the basal joint black, distinctly compressed, the medial joints on the flattened side not quite twice as long as wide; prothorax two-fifths wider than long, the sides strongly arcuate, less so and oblique posteriad to the angles, which are right and sharp, with the sides before them parallel and 134 MEMOIRS ON THE COLEOPTERA straight for a very short distance; surface convex, strongly, rather sparsely and somewhat unevenly punctate; median line partial, very fine; elytra long, two- thirds longer than wide, evidently wider than the prothorax, parallel, with nearly straight sides and obtusely rounded apex; strie fine; two rows of the intervals with the punctures moderate, deep, separated by fully their own lengths; surface between the rows rather convex, being rather prominent when viewed under transverse illumination; scutellar stria very fine, rather short; anterior male tarsi moderately dilated. Length (@@) 5.7-6.8 mm.; width 2.15-2.35 mm. California (Del Norte Co.),—Nunenmacher. A very distinct slender species, the smallest known to me at present; it cannot be the brunneus of Dejean, as this has the pro- thorax only a little wider than long and but feebly rounded at the sides and having much denser coarse punctuation; brunneus prob- ably forms part of the piceus group, though only 6 mm. long. Dicheirus gracilis n. sp.—Narrow, parallel, black throughout, the legs dark rufous; erect sete sparse, only moderate in length; head rather small, though two-thirds as wide as the prothorax, the eyes notably prominent; surface coarsely and closely punctured, a little more loosely so medially; antennz rather thick, piceous, the medial joints on the compressed side two-thirds longer than wide; prothorax barely a third wider than long, widest at apical third, the arcuate sides becoming gradually less rounded and oblique posteriad, the angles obtuse but not rounded and slightly prominent; surface nearly even, strongly and sparsely punctate; lateral edges very fine; elytra three-fifths longer than wide, parallel, with scarcely at all arcuate sides and broadly, subcircularly rounded apex, a little wider than the prothorax; punctures of the two interstrial series strong and rather close-set, the surface between the series narrowly convex by lateral illumination; striz fine, the scutellar short and very fine; flanks with a series of coarse punctures in basal fourth and apical third. Length ( 2) 6.7 mm.; width 2.65 mm. Washington State (Govan). One example. Allied only to exiguus, but differing in its slightly larger size, more parallel form, much less abbreviated prothorax and longer antenne; the coarse serial punctures along the elytral flanks are similar. All of the following species pertain to the piceus group of the genus, which is distinguished not only by the more subcylindric form of the body and less basally narrowed prothorax, but by very sparse and inconspicuous erect sete. Dicheirus incidens n. sp.—Parallel, rather convex, polished, extremely pale rufo-testaceous throughout, the elytra, but not the scutellum, rather dark piceous, the reflexed lateral margins testaceous; head two-thirds (co), nearly three-fourths (9), as wide as the prothorax, with not very prominent eyes, coarsely, sparsely punctate, impunctate centrally; antenne rather dark testaceous, the flattened sides of the medial joints not quite twice as long as wide; prothorax a fourth () to not quite a third (@) wider than long, the sides broadly arcuate, slightly converging and straight basally, the angles moderately rounded; surface as usual evenly convex, very feebly impressed basally near outer fourth; punctures moderately coarse, sparse throughout; median line distinct from the basal margin ADDITIONS TO NORTH AMERICAN COLEOPTERA 135 not quite to the apex; elytra nearly two-thirds longer than wide, evidently wider than the prothorax, parallel, with feebly arcuate sides; oblique sides of the apex with rather long distinct sinus; surface feebly alutaceous distally in the female; striz moderate; intervals very convex (<7), nearly flat (9); two series unusually widely separated, the punctures fine, unevenly but often remotely separated; anterior male tarsi rather narrowly dilated. Length (o@ @) 7.3-8.3 mm.; width 2.85-3.0 mm. Oregon (Columbia River),—Shantz. Three specimens. One of the more isolated species of the genus, by reason of its peculiar pale coloration, fine and widely separated series of the strial intervals, the latter in the male differing greatly from those of the female and very much more strongly convex than those of piceus (co), also with more narrowly dilated anterior tarsal joints in that sex. Dicheirus facilis n. sp.—Obscure rufous throughout, the legs slightly clearer, the elytra and scutellum deep black, parallel, convex and shining, the elytra slightly alutaceous apically but not thence to the base; head three-fifths as wide as the prothorax, strongly punctate, subimpunctate centrally; eyes well devel- oped, but only moderately prominent; antenne obscure rufous, long, the medial joints about twice as long as wide on the flattened side; prothorax large, two- fifths to three-sevenths wider than long; base as usual arcuate laterally, only a little narrower than the maximum width; surface feebly impressed at base near lateral fifth; punctures coarse, deep, sparse and somewhat uneven; elytra parallel, gradually obtusely ogival at apex, three-fourths longer than wide, slightly though evidently wider than the prothorax; strie fine; intervals very feebly convex, the punctures of the double series strong and very widely though unevenly separated; scutellar stria rather long but fine, free; subapical sinuses long and very distinct. Length (9) 9.2-9.5 mm.; width 3.35-3.45 mm. Oregon (Columbia River),—Shantz. Two specimens. Resembles piceus, but is materially larger and differs also in coloration; the prothorax is unusually transverse. Dicheirus sodalis n. sp.—Elongate, subparallel, strongly convex, shining, deep black throughout, the legs very dark, blackish-piceous; head coarsely and loosely punctate, well developed, nearly three-fourths as wide as the prothorax, the eyes moderate in size and prominence; antenne piceous, as usual rather stout; prothorax unusually long, only a fourth wider than long, parallel, the sides feebly arcuate, a little more oblique and straight basally, the angles very obtuse but with scarcely rounded apex; surface not very coarsely, somewhat unevenly and very sparsely punctate; elytra parallel, rectilinear, three-fifths longer than wide, a little wider than the prothorax, obtusely ogival at apex, with distinct shallow sinuses; striz moderate, abrupt, the intervals feebly convex; punctures of the double lines rather strong, very unequally well spaced. Length (9) 8.8 mm.; width 3.25 mm. Washington State (Wawawai). One example. Also allied to piceus but larger; it differs from the preceding in coloration and more especially in its larger and very much less transverse prothorax. ; Dicheirus piceus Ménet., extends in moderate numbers from San Francisco to Washington State. The sutural interval in this, 136 MEMOIRS ON THE COLEOPTERA as well as most other species of the picews group, all of which are more or less closely interallied, bears only a single series of minute and very remote punctures, placed externally and easily overlooked. Anadaptus Csy. But few new forms in this genus have been discovered in recent years. There are two distinctly demarcated divisions of the genus, one with uniform elytral surface, the other with the alternate strial intervals smooth and coarsely punctate. The following is allied to baltimorensis: Anadaptus uteanus n. sp.—Shining, black above and beneath, the elytra uniform pale red-brown, the epipleura similarly pale and also the entire legs; head rather large, with broad and uneven anterior impressions, the eyes somewhat prominent and well developed; antenne fuscous, with paler basal joint, the compressed medial joints three-fifths longer than wide; prothorax fully a third wider than long, the rounded sides becoming convergent and broadly sinuate basally, the angles right and sharp; surface densely punctate basally and finely, sparsely and feebly so apically, the transverse impression feeble, that at lateral fourth at base rounded and deeper; elytra four-sevenths longer than wide, nearly a fifth wider than the prothorax, parallel, with feebly arcuate sides; strie rather coarse, sharply and deeply grooved, the scutellar long; intervals (9 ) very feebly convex; puncture of the third, adjoining the second stria, strong, deep and at three-fifths. Length (2) 10.3 mm.; width 4.2mm. Utah (Stockton),—Mr. Tom Spalding. Differs from baltimorensis in its larger size, stouter form, larger head and especially the larger eyes, also by the more deeply sinuate sides of the prothorax toward the basal angles. From nivalis Horn, it differs in its larger head and eyes and absence of the characteristic discal piceous area of the elytra. In all these species the scutellar stria is well developed, rather arcuate and tends to join the first stria; it is longer as a rule in wfeanus than in the common balti- morensis. Anisotarsus Chd. The species of this genus are numerous; the body is much more loosely articulated and with thinner integuments than in either Antsodactylus, Triplectrus or Anadaptus. The following are nu- merous undescribed species, more or less recently discovered: Anisotarsus hebes n. sp.—Suboblong-oval, moderately convex, black, the elytra with greenish lustre, the legs rufous, also with narrow testaceous pronotal border; surface polished, the elytra only faintly alutaceous in the female; head small, only slightly more than half as wide as the prothorax, subtriangular, the eyes moderate in size and prominence; antenne slender, testaceous; prothorax three-sevenths wider than long, the sides feebly and subevenly arcuate, nearly parallel basally, slightly converging apically, the basal angles slightly more than AppITIONS TO NORTH AMERICAN COLEOPTERA 137 right and narrowly blunt; surface smooth, nowhere punctate, the sides narrowly subexplanate, a little more broadly behind, having at the middle a large puncture; briefly linear impression at outer fourth of the base obvious but feeble; transverse impressions very feeble, the fine median line visible only centrally; elytra parallel, with arcuate sides and rather obtuse apex, three-fifths longer than wide and three- sevenths wider than the prothorax; strie very fine, gradually less so and more impressed inwardly, the scutellar moderate; intervals feebly convex, more so suturally, nearly flat in the female, the puncture of the third adjoining the second stria near apical fourth; anterior male tarsi moderately dilated. Length (#9) 9.0 mm.; width 3.9-4.0 mm. Texas (Dallas). Three specimens. Allied to terminatus Say, but decidedly shorter and broader and with relatively shorter and more inflated hind body. Anisotarsus angusticollis n. sp.—Outline much narrower than in ferminatus, similar to the preceding in coloration and lustre, the sides of the pronotum more abruptly though but little more broadly deplanate and rather less narrowly testaceous; legs very pale; head similar, though relatively larger, being two-thirds as wide as the smaller and much narrower prothorax; eyesa little larger; anterior impressions rather large, shallow and indefinite, somewhat rounded; antenne testaceous, long and slender; prothorax barely a third wider than long, the sides feebly arcuate, subparallel, a little more rounded anteriad, the basal angles barely more than right, not very broadly but distinctly rounded; surface smooth, the basal impressions—within lateral fourth—small and feeble; transverse impres- sions not quite obsolete; apex a little less sinuate than in the preceding; elytra narrow, elongate, polished and greenish, suboval and nearly twice as long as wide, between a fourth and third wider than the prothorax, less obtuse at apex; strie nearly similar, the discal puncture near apical fifth; anterior male tarsi evidently though rather narrowly dilated. Length (co) 8.0 mm.; width 3.2 mm. Missouri (St. Louis). Two specimens. This is the narrowest and one of the smaliest species allied to lerminatus, and is very distinct in all its characters. The two following species may come between calathoides and testaceus, but are obviously distinct from either: Anisotarsus fuscipennis n. sp.—Oblong-suboval, moderately convex, polished throughout (<7), the elytra strongly alutaceous (@), pale flavo-testaceous in color throughout, the elytra piceous; head moderately small, scarcely four- sevenths as wide as the prothorax, with rather large but only moderately convex eyes, the anterior strioles small and slender, within large indefinite impressions; front with an impressed puncture midway between the eyes; antenne long, slender, only feebly compressed and testaceous; prothorax two-fifths (o”) or nearly one-half (2) wider than long, the sides feebly arcuate, more so and evi- dently converging anteriad, the basal angles a little more than right and narrowly rounded; surface nearly smooth, abruptly deplanate at the sides, more broadly and gradually toward base; subbasal impression at outer fourth large, rounded and shallow; apex almost truncate, only very feebly sinuate; elytra four-sevenths longer than wide, with parallel arcuate sides, nearly a third wider than the pro- thorax; strie moderate, only a little coarser distally, the scutellar well developed; adherent puncture of the second near apical fourth; anterior male tarsi moder- ately dilated. Length (79) 8.0-8.4 mm.; width 3.3-3.6 mm. Wisconsin (Bayfield) and Michigan (Marquette). Four specimens. 138 MEMOIRS ON THE COLEOPTERA This distinct species may be placed near ftestaceus, but it is much more abbreviated and the elytra are piceous-brown; the female is obviously broader than the male. Anisotarsus parallelus n. sp.—Subparallel but with broadly arcuate sides, rather strongly convex and with unusually dense integuments, black throughout, with slightly picescent prothorax, the legs testaceous; head four-sevenths as wide as the prothorax, with well-developed and rather prominent eyes, the strioles and impressions almost as in the preceding; antennz slender, fuscous, almost entirely wanting in the type; prothorax rather large, two-fifths wider than long, the sides subparallel and feebly arcuate, gradually more arcuate and strongly converging anteriad, the basal angles somewhat broadly rounded; surface with some transverse striolate rug, nearly smooth, abruptly concavo-explanate laterally, becoming broadly flat posteriorly; basal impressions at outer fourth slender and feeble; median line very fine and feeble, visible only centrally; apex feebly sinuate; elytra notably long, about three-fourths longer than wide, parallel, with broadly arcuate sides and gradually obtusely ogival apex, barely a fifth wider than the prothorax; striz fine and superficial, more distinct and feebly impressed suturad, the scutellar rather long; intervals flat; small puncture of the third near the second stria and at three-fourths. Length (9) 8.6 mm.; width 3.4 mm. Missouri (St. Louis). ; The integuments are denser and firmer in this species than in any of the allies of sayz and terminatus, and it is also rather isolated in its relationship; the elytral strie become a little coarser at apex. Anisotarsus subovalis n. sp.—Elongate-suboval, convex, shining, blackish- piceous above and beneath, the head, pronotum and epipleura slightly paler, rufescent; lateral reflexed margins more testaceous; legs pale rufo-testaceous; head barely as long as wide, four-sevenths as wide as the prothorax, with well- developed prominent eyes and obsolete apical strioles; antennz fusco-testaceous, the first two joints slightly paler; prothorax fully three-sevenths wider than long, the sides broadly arcuate, less so and feebly oblique posteriorly and more so anteriad; base transverse, a third wider than the very moderately sinuate apex having rather obtusely rounded angles, the basal slightly more than right and blunt; surface smooth throughout, the narrow impression within lateral fourth very feeble, the median line very fine, much abbreviated anteriad; elytra subparallel, with distinctly arcuate sides, obtusely ogival apex and distinct sinuses, convex, three-sevenths longer than wide and nearly a fourth wider than the prothorax; strie notably fine, smooth, subexarate on the declivity; intervals flat, with a feeble puncture on the third, adjoining the second stria a little beyond three-fourths; scutellar stria very fine, proceeding from a distinct impressed puncture; anterior male tarsi moderately dilated, subparallel. Length (co) 7.0 mm.; width 2:85 mm. Missouri (Charleston),—Wade. Although comparable with terminatus, this species is smaller, with much shorter and more oval elytra, the sides not more rounded basally as they are in that species. Anisotarsus inerrans n. sp.—Short, oblong, moderately convex, highly polished throughout (<7), deep black, without metallic lustre, the lateral edges of the pronotum and elytra toward apex at the sides obscure testaceous; legs pale, flavate, the cox more obscure; head nearly three-fifths as wide as the prothorax, ADDITIONS TO NORTH AMERICAN COLEOPTERA 139 somewhat wider than long, the eyes moderate, the anterior strioles almost obsolete; antenne slender, testaceous; prothorax four-sevenths wider than long, parallel, the sides evenly and rather strongly arcuate; basal angles distinctly rounded; apex narrower than the base, very slightly sinuate; surface smooth, rapidly declivous to the very finely reflexed edges in about apical half, the sides thence more gradually declivous; impression at outer fourth small, very feeble and scarcely visible; elytra less than one-half longer than wide, slightly wider than the prothorax, parallel, with feebly arcuate sides and obtusely ogival apex, the sinuses distinct; stri@ very fine, much deeper on the declivity, slightly impressed toward the suture, the intervals flat—almost so suturally; the puncture small, between two-thirds and three-fourths, the scutellar stria long, tending to unite with the first; anterior male tarsi very moderately dilated. Length (7) 7.3 mm.; width 3.0mm. Missouri (St. Louis). This species is allied in some respects to the small and rather broadly oblong Texan species, which I identified as agzlis Dej., and was considered under that head in my revision of the genus, but it is evidently different, having the male prothorax broader than in the female of agzlis, and with the sides very much more strongly arcuate. The species described by LeConte as nitidipennis is at least very closely related to tenuitarsis, as shown by the “accurately flat”’ strial intervals, as well as the notably large head, and it may be identical although it inhabits a more tropical environment, but the less flat intervals of cephalus, as well as the deeper suturally im- pressed striz, show that this is not a varietal form of either nztidi- pennis or tenuitarsis, but a distinct species. The following two species belong to the floridanus group: Anisotarsus connivens n. sp.—Oblong-oval, rather convex, highly polished throughout in the male, the female unknown; blackish-piceous in color, the pronotum and under surface dark rufous, the legs pale flavate; head four-sevenths as wide as the prothorax, with notably prominent eyes, the anterior strioles very minute, punctiform, at the bottom of shallow impressions, the interocular puncture small and feeble; antennz slender, fuscous, testaceous basally; pro- thorax slightly more than one-half wider than long, the sides rather strongly, subevenly arcuate, a little more converging anteriorly, the basal angles obtuse and narrowly rounded; surface smooth, steeply declivous at the sides to a narrow and rather abrupt deplanature, becoming a broad convex feebly declivous surface basally; basal impression at outer fourth elongate and obtusely though deeply impressed; anterior transverse impression fine, sharp, angulate and distinct; apex broadly, rather shallowly sinuate as in floridanus; elytra rather less than one-half longer than wide, oval, with arcuate sides, about a fifth wider than the prothorax; striz# moderate, sharp, not much coarser distally; gradually stronger but only slightly impressed suturally; intervals very feebly convex; posterior puncture as in floridanus but smaller; anterior male tarsi moderately dilated. Length (@) 7.75 mm.; width 2.9mm. Florida (Marion Co.). Easily distinguishable from floridanus—though rather closely related—by the relatively broader hind body or less parallel outline, piceous and not so metallic elytra and by the dark rufous prothorax. 140 MEMOIRS ON THE COLEOPTERA Anisotarsus vernicatus n. sp.—Obtusely oval, convex, broader and much less parallel than floridanus, highly polished (), black, with greenish lustre, the head and prothorax very dark rufo-piceous; under surface and legs nearly as in connivens; head in size and structure almost as in that species, the central puncture still more nearly obsolete, barely traceable; slender antenne differing in being entirely very pale testaceous; prothorax less transverse, scarcely one-half wider than long and with the apex almost rectilinearly truncate; sides as in connivens, the smooth surface nearly similar, except that the steeply sloping sides extend to the finely reflexed margin, and the anterior transverse impression is almost obsolete; basal impressions long, obtuse and deep; median stria very fine, partially obsolete; elytra oblong-oval, with parallel and somewhat arcuate sides, a little over one-half longer than wide and fully a fourth wider than the prothorax; striation still finer than in connivens or floridanus and scarcely at all coarser on the declivity, much more impressed suturally than in the former, but about the same as in floridanus; puncture more posterior than in either and about at apical fifth; anterior male tarsi very moderately dilated. Length () 8.0 mm.; width 3.25 mm. Florida (Everglade Co.). Differs from floridanus in its broader and more ventricose outline and very much less parallel sides and, from both floridanus and connivens, in its more nearly truncate thoracic apex, non-explanate pronotal margins and other important features. Glycerius Csy. Mr. Fall was good enough to exchange a specimen of his politus, intermedius and obtusus, so that I am now able to make known a few nondescripts in my collection. Politus is, I think, the most abundant species in California, and is widely distributed, but the other two.seem to be much more restricted in habitat; the following three species are quite distinct: Glycerius curticollis n. sp.—Of a somewhat piceous black, polished and bright zeneo-metallic lustre, the legs pale flavate, slender; head two-thirds as wide as the prothorax or slightly more, with moderate but very prominent eyes, the anterior strioles strong and very oblique; antenne slender, blackish, with pale basal joint, only feebly compressed; prothorax short and transverse, about four-sevenths wider than long, the’ sides moderately inflated and rounded just beyond the middle, oblique, becoming very feebly sinuate thence to the base, the angles rather distinct, slightly more than right; surface smooth, the sides steeply declivous to the margin, the transverse impressions vestigial; basal impression just outside of lateral fourth shallow and finely, sparsely punctate; elytra one-half longer than wide, a fifth wider than the prothorax, parallel, with feebly arcuate sides and evenly rounded apex; discal striae wholly obsolete, the sutural and external distinct. Length 4.15-4.4 mm.; width 1.65-1.7 mm. California (Monterey). Two specimens. C Differs from politus in its much shorter and broader prothorax, longer antenne and decidedly longer tarsi. Glycerius tahoensis n. sp.—Smaller, polished, piceous-black, the elytral suture slightly paler; legs testaceous; head as in the preceding but smaller, the antenne ADDITIONS TO NORTH AMERICAN COLEOPTERA 141 similar in color but shorter and relatively thicker; prothorax not quite one-half wider than long, very moderately rounded at the sides, the latter feebly converging and just visibly sinuate behind, the angles distinct, barely more than right; apex subtruncate; surface smooth, the basal impressions feeble and with some fine sparse punctures; elytra nearly one-half longer than wide, parallel, with feebly arcuate sides and gradually rounded apex, not quite a third wider than the prothorax; sutural stria deeper and less abbreviated at base than in the preceding, the general surface with feeble vestiges of strie; tarsi shorter. Length 3.8 mm.; width 1.4-1.45 mm. California (Lake Tahoe). Two specimens. Excepting obtusus, this is the smallest species known to me; it differs greatly from cwurticollis in the total absence of the bright geneous lustre of the latter, more truncate thoracic apex, more visible elytral striation, in the sutural stria as mentioned above and in the shorter antenne and tarsi. It is larger than obtusus and differs in its non-zneous lustre, longer antenne and more parallel form, with much more parallel and less oval hind body. Glycerius laticollis n. sp.—Elongate, parallel, convex, polished and with non- metallic lustre, piceous-black, the pronotum sometimes feebly, nubilously paler at apex and base, the elytral suture slightly pallescent; legs flavate as usual; head nearly as in the two preceding but smaller and with less prominent eyes; antenne similar but somewhat longer; prothorax larger and less transverse, barely three-sevenths wider than long, the sides parallel, distinctly arcuate, slightly oblique and nearly straight behind; surface almost similar, but with rather more evident transverse impressions and more numerous and stronger punctures in and near the basal impressions; apex barely perceptibly sinuate; elytra longer, almost three-fifths longer than wide, parallel, with as usual nearly straight, basally arcuate sides and rapidly obtusely rounded apex, only about a fourth wider than the prothorax; sutural stria more acute and less impressed than in tahoensis, the surface rarely with faint vestiges of striation. Length 4.0-4.15 mm.; width 1.6-1.65 mm. Nevada (Reno). The male is more abbreviated than the female and with just visibly broader anterior tarsi. This species is smaller, narrower and more parallel than politus, and differs from tahoensis in its much larger prothorax, less impressed sutural stria and other characters. The head and prothorax in intermedius are smaller than in any other species, giving to this very smooth form a dis- tinctive appearance. Stenocellus Csy. This will prove to be a large genus of widely extended distribution in North America. It is very close in general facies to the usual form of Acupalpus, but, besides the mentum tooth, given as a distinguishing feature in my arrangement in Mem. Col., V, it will be observed that the hind tarsi are usually more elongate in Steno- cellus. Besides this, the scutellar stria is wanting in Stenocellus, T. L. Casey, Mem. Col. XI, Mar. 1924.—10 142 MEMOIRS ON THE COLEOPTERA but distinct and parallel though short in Acupalpus. The two fol- lowing species seem to be undescribed as yet: Stenocellus carolinensis n. sp.—Rather narrow, moderately convex, polished, pale testaceous, the anterior parts of the head and most of the elytra, excepting the suture, shaded darker; under surface and legs pale; head unusually large, four-fifths as wide as the prothorax, with notably prominent eyes and large deep apical fovew, which are obliquely prolonged toward the eyes by a short fine groove; antenne moderately long, obscure, the first two joints pale; prothorax a fourth wider than long, the sides moderately oblique and arcuate from near apex to the obtuse but sharp basal angles; transverse impressions evident medially but obtuse, the basal impression near outer fifth deep, feebly and narrowly punctate; elytra about one-half longer than wide, with subparallel and feebly arcuate sides and rapidly rounded humeri, about a fifth wider than the prothorax, the stria moderate but evidently impressed, especially suturad; hind tarsi slender, rather shorter than usual. Length 2.5 mm.; widtho.8mm. North Carolina (Southern Pines), —Manee. The neck is rather long and parallel behind the notably prominent eyes. This species may be placed next to Jarvatus in my original table, which species also has a large head and prominent eyes, but here the antenne are heavier, the prothorax less transverse and the general coloration not so pallid; /arvatus inhabits the arid regions about El Paso, Texas. Stenocellus veronianus n. sp.—Very small, slender, convex, polished; anterior parts testaceous, the pronotum paler; elytra black; under surface piceous, the very slender legs pale yellow; head nearly three-fourths as wide as the prothorax, the eyes prominent; surface notably convex, smooth, the anterior fovee very widely impressed; antennz fuscous, the first two joints pale testaceous, slender, gradually incrassate distally, extending about to the middle of the body; pro- thorax smooth and convex, a fifth wider than long, widest beyond the middle, with the sides subevenly arcuate, more converging basally; base fully three- fourths as wide as the subtruncate apex, which has obtuse and slightly blunt angles, the basal angles obtuse but minutely, bluntly subprominent; transverse impressions very feeble, the median stria very fine, subentire; sublateral impres- sions at base rounded, very shallow and finely, sparsely punctulate; elytra parallel, barely at all arcuate at the sides, circularly rounded at apex, two-thirds longer than wide and about a third wider than the prothorax, feebly and nubilously rufescent at base; striz deeply impressed, smooth, the scutellar wanting as usual; intervals moderately convex; discal puncture of the third at three-fifths; anterior male tarsi with the basal joint feebly dilated. Length () 2.35 mm.; width 0.78 mm. Florida (Vero),—Wade. This species, one of the smallest of the genus, may be placed near carolinensis, but it is narrower and has longer antenna, among other differences. Stenocellus humboldtianus n. sp.—Oblong, moderately convex polished, pale testaceous, the elytra obscure near the suture, the under surface of the hind body rufo-piceous; legs pale flavate; head three-fourths as wide as the prothorax, with rather large, moderately prominent eyes; central puncture of the front AppiTions TO NORTH AMERICAN COLEOPTERA 143 distinct, the apical fovee large and deep; antenne moderate, fusco-testaceous, paler basally; prothorax a fourth wider than long, the broadly and subevenly arcuate sides but slightly oblique posteriad, the angles broadly obtuse and somewhat blunt; apex barely visibly sinuate, somewhat narrower than the base; latero-basal impressions moderate, finely and closely punctate; elytra but little more than one-half longer than wide, obtusely rounded at apex, the parallel sides feebly arcuate, scarcely a third wider than the prothorax; striae strong, deeply impréssed, more shallowly outwardly. Length 4.2 mm.; width 1.4 mm. Cali- fornia (Hoopa Valley, Humboldt Co.). Somewhat resembles /ineatus, but larger, with larger and more prominent eyes, rather more transverse prothorax and more obtuse and less sharply marked basal thoracic angles. From nubicollis it differs in its much less abbreviated prothorax, rather less promi- nent eyes and less elongate antenne. Of neglectus Lec., of which I had no representative in my revision of the genus—being forced to quote the description of LeConte, I have recently obtained a number of specimens from Marquette, Lake Superior, and Edmonton, Alberta; festinans, from an un- recorded locality in Texas and from Sedgwick Co., Kansas, is more elongate and also with longer antenne, more prominent eves and more convex strial intervals; szavis, from Austin, Texas, is narrower, with less transverse prothorax and much larger and more prominent eyes, as well as more convex strial intervals. The broadly rounded basal thoracic angles will readily identify all three of these species. Acupalpus De}. The American species of this genus are smaller and more abbre- viated than most of the European, so far as I can judge, and it is possible that they may some day be separated as a subgenus. To the five species hitherto known, the following three should be added: Acupalpus subrectus n. sp.—Rather broadly oblong, moderately convex, polished, testaceous, the elytra and head blackish, the under surface of the hind body, excepting the pale epipleura, obscure; head notably large, with moderate though prominent eyes, four-fifths as wide as the prothorax; antennz slender, obscure, very moderate in length; anterior fovee narrow, oblique, the central puncture evident; prothorax transverse, nearly one-half wider than long, the sides broadly arcuate, moderately oblique behind, the large latero-basal impres- sions rounded, smooth and deep, not distinctly punctate; apex broadly, almost rectilinearly truncate, much wider than the base; elytra very nearly one-half longer than wide, parallel and feebly arcuate at the sides, rapidly and obtusely rounded at apex, almost two-fifths wider than the prothorax; striae somewhat deeply impressed; tarsi short but rather slender. Length 2.6-2.8 mm.; width 0.9-1.0 mm. Northern Illinois (Beverly Hills)—A. B. Wolcott. Three speci- mens. 144 MEMOIRS ON THE COLEOPTERA The notably large head, with prominent eyes, is nearly as in hydropicus and expertus, but in the former the size is smaller, the outline more abbreviated, with more inflated elytra and the thoracic sides more strongly oblique; in expertus the body is narrower and the prothorax less transverse, among other differences. Acupalpus curtipennis n. sp.—Oblong, moderately convex, shining, piceous, the prothorax slightly paler; under surface blackish, the epipleura, hypomera and legs flavate; head large, not quite as wide as the prothorax, the eyes moderate, not very prominent; anterior impressions lineiform and, as usual, strongly and outwardly oblique; central puncture distinct; antenne long, fuscous, the first joint pale, the second piceous; prothorax unusually narrow, only very slightly wider than long, widest near apical two-fifths, the sides moderately arcuate, slightly oblique and nearly straight posteriad, the angles very obtuse and some- what blunt; outer basal impressions rather narrow, scarcely punctate, the median line deeply impressed but only extending to apical third; elytra parallel and broad, scarcely over two-fifths longer than wide, very obtusely rounded at apex, fully two-fifths wider than the prothorax; strie# smooth, distinctly impressed, the scutellar stria distinct and parallel, moderately long; legs short, the tarsi some- what longer than usual, slender. Length 2.7 mm.; width 1.1 mm. Northern Illinois. Mr. A. B. Wolcott. One specimen. The broad elytra, unusually narrow prothorax and large head give this species a very peculiar appearance, unlike any other known to me. Acupalpus canadensis n. sp—Suboblong, rather narrow and strongly convex, polished and deep black, the prothorax barely visibly picescent; legs more or less piceous; head three-fourths as wide as the prothorax, strongly convex, with the usual very oblique apical lines, the central puncture feeble or almost obsolete; eyes large but only moderately prominent; antenne moderately long, gradually _ a little thicker from base to apex, blackish, paler at base; prothorax fully a third wider than long, widest at anterior two-fifths, the sides distinctly rounded, oblique and straight in about basal half, the angles very obtuse and slightly blunt; latero-basal region sparsely punctate, the impression rounded and at outer fifth; median line moderate but almost attaining the apex, the latter only just visibly sinuate; elytra nearly one-half longer than wide, parallel, with distinctly arcuate sides and rather obtusely rounded apex, barely a third wider than the prothorax; striz fine, moderately impressed, the scutellar fine and feeble, parallel; intervals feebly convex; hind tarsi very slender and filiform, but much shorter than the tibia. Length 2.6 mm.; width 0.85 mm. Canada (Mt. Royal, Quebec). One specimen. This species is quite distinct from any other known at present in its deep black and unusually convex, polished surface and piceo- testaceous legs. Stenolophus Dej. The numerous species of this genus are much larger than those of Stenocellus and Acupalpus, except in extreme cases, and the body is broader than in either of those genera. The basal angles of ADDITIONS TO NORTH AMERICAN COLEOPTERA 145 the prothorax are rather widely rounded, and the antenne and legs are long. The following five species appear to be hitherto unre- corded: Stenolophus testaceicollis n. sp—Rather narrower than usual, moderately convex, polished, the head black, the elytra very nearly black, nubilously paler along the sides, the suture also pale, the surface somewhat iridescent; entire under surface and legs and also the entire prothorax pale flavo-testaceous; head well developed, fully three-fourths as wide as the prothorax, notably convex, the anterior oblique sulci coarse, the central puncture distinct but shallow; eyes rather large, moderately prominent, the antenne long, slender, blackish, the first two joints pale; prothorax only a fourth or fifth wider than long, parallel, the sides broadly arcuate, slightly widest a little beyond the middle, the angles broadly rounded; surface nearly smooth, the latero-basal impressions large, shallow and finely punctate, somewhat punctiform at basal fifth; median line obsolete; transverse impressions feeble; apex subtruncate; elytra three-fourths longer than wide, barely a fourth wider than the prothorax, the parallel sides very feebly arcuate; apex gradually rounding, not obtuse; striae deep, acute, the scutellar strong, approaching the first; intervals nearly flat, the puncture of the third near the second stria at two-thirds; legs slender. Length 5.5 mm.; width 1.85 mm. Rhode Island (Boston Neck). A single female. This species is allied only to ochropezus, but differs in its narrower outline, quite radically in coloration and in its less obtuse elytral apex. Stenolophts floridanus n. sp.—Oblong-suboval, moderately convex, in color and lustre throughout as in ochropezus; head not quite three-fourths as wide as the prothorax, with rather large and prominent eyes, coarse oblique apical strioles and distinct central puncture, the antennz long, slender and piceous, the first two joints testaceous; prothorax as in ochropezus but more abbreviated, nearly a third wider than long; elytra more oval, the sides gradually rounding behind; strie coarse and deep, the intervals moderately convex, Length 4.6 mm.; width 1.7mm. Florida. Differs from ochropezus in its smaller size, slightly more slender antennez, shorter prothorax, with deeper anterior transverse im- pression, and in the more rounding sides of the elytra posteriorly, the apex much less obtuse—in fact suturally rather prominent, also in the coarser striae and narrower intervals. Stenolophus extensicollis n. sp.—Notably elongate, moderately convex, pol- ished, the elytra with strong iridescent lustre; color rufo-testaceous, the elytra indefinitely blackish discally; under surface blackish, the epipleura and legs rufous; head nearly three-fourths as wide as the prothorax, with large and prominent eyes, the apical fovee parallel, impressed, not very deep; antenne slender, fuscous, gradually paler basally, extending to basal fourth of the elytra, the medial joints rather more than three times as long as wide; prothorax scarcely a fifth wider than long, the sides subevenly arcuate, a little more converging basally, the angles broadly rounded; base slightly narrower than the apex, which is very feebly sinuate, with rounded angles; side margins extremely finely reflexed; disk smooth, with some fine feeble ruguliform transverse lines, the 146 MEMOIRS ON THE COLEOPTERA median parts slightly darker than the periphery; impressions subobsolete through- out, the latero-basal parts just visibly and indefinitely impressed; median line fine; elytra parallel, with feebly arcuate sides and obtusely rounded apex, with feeble sinuses, four-sevenths longer than wide and nearly a third wider than the prothorax; striae smooth, deeply impressed, the scutellar rather long, fine and free; intervals moderately convex, the small discal puncture of the third near three-fourths, adjoining the second stria as usual; male anterior tarsi narrowly dilatéd. Length (co) 6.4 mm.; width 2.4 mm. Arizona (Tempe),—Wade. One specimen. Allied to anceps, peregrinus and some others, but larger and with much less abbreviated prothorax. From Tempe, Arizona, I have a large series from Mr. Wade exactly similar to ochropezus in every way. It is altogether dis- similar from extensicollis and I do not think it could be gracilis Csy. Stenolophus rivularis n. sp.—Oblong-oval, rather convex, polished black, the fine reflexed thoracic sides, also the epipleura and hypomera, testaceous, the legs flavate; head scarcely two-thirds as wide as the prothorax, the moderate eyes only slightly prominent; apical oblique strioles very short, remote from the eyes, the central puncture small, almost obsolete; antenna long, slender, fuscous, the first two joints testaceous; prothorax nearly a third wider than long, slightly widest beyond the middle, the sides subevenly arcuate, the angles broadly rounded; transverse impressions obsolete, the latero-subbasal impressions large, very shallow and rugose basally; median line shallowly im- pressed, slightly biabbreviated; apex evidently sinuate; elytra broad, oblong, with rather strongly arcuate parallel sides and rapidly broadly obtuse apex, three-sevenths longer than wide and three-sevenths wider than the prothorax; striae smooth, moderate, gradually more coarsely, deeply impressed and with convex intervals suturad; puncture fine and feeble, adjoining the second stria slightly beyond two-thirds; scutellar stria short. Length 5.3 mm.; width 2.0 mm. Missouri (St. Louis). The single male specimen at hand represents a species allied evidently to humidus Ham., of which I have a male from West Point, N. Y., but is much more ventricose, with somewhat longer antenne, distinctly less prominent eyes and more impressed elytral stria; it is noticeably larger in size. Stenolophus curticollis n. sp—Oblong, moderately convex, polished, black, the elytra rufo-piceous; under surface black, the legs obscure testaceous; head only three-fifths as wide as the prothorax, the eyes moderate, not very prominent; antenne shorter than in plebejus and much thicker, the medial joints barely twice as long as wide; prothorax three-sevenths wider than long, the sides sub- evenly arcuate; basal angles broadly rounded; base just visibly wider than the moderately sinuate apex; surface smooth, the median line fine but rather strong, slightly abbreviated; basal impressions near outer fourth shallow and sparsely punctate; elytra three-sevenths longer than wide, only about a fourth wider than the prothorax, parallel, with feebly arcuate sides and rapidly obtusely rounded apex; strie fine, barely impressed, the scutellar short and fine but distinct; intervals barely at all convex, similar at apex, the fine discal puncture only very little behind the middle. Length (9) 5.0 mm.; width 1.7 mm. Maryland (Somerset ),—Wade. ADDITIONS TO NORTH AMERICAN COLEOPTERA 147 This distinct species may be placed near plebejus but differs in many ways. The head is a little smaller, the antennae much thicker, the prothorax shorter and more transverse, with the middle of the apical margin feebly testaceous, and the strial intervals are nearly flat throughout, not narrower and more convex as they are on the subexarate apex of plebejus. Tachistodes Csy. These former associates of Acupalpus and Agonoderus are moder- ately numerous; they are all among the smallest of the Harpaline. The three following species I believe to be undescribed: Tachistodes lyratus n. sp.—Oblong, subparallel, convex and polished, piceous in color, the legs flavate, slender, with short slender hind tarsi; head moderate, but little over two-thirds as wide as the prothorax, with rather small and not notably prominent eyes, coarse oblique apical impressions, finely prolonged to the eyes, and a distinct central puncture; antenne rather short, fuscous, paler basally; prothorax only a fifth wider than long, gradually slightly narrowed from apex to base, with evenly and moderately arcuate sides; apical angles narrowly, the basal broadly, rounded, the apex barely perceptibly sinuate; surface notably convex, distinctly punctured apically and latero-basally, the basal impressions small, near outer fifth, impressed; median line coarse, not quite attaining the apex; elytra parallel, with feebly arcuate sides and obtusely rounded apex, three- sevenths longer than wide, about a third wider than the prothorax; striz smooth, coarse and deep, the scutellar extremely short; intervals convex. Length 3.0 mm.; width 1.0mm. _ Kansas. Somewhat allied to pauperculus and humilis, but with less narrowed thoracic base than in either; pauperculus is bicolored and the prothorax in both is more transverse. Tachistodes obscurus n. sp.—Parallel, polished, piceous-black, the prosternum, epipleura and legs pale; periphery of the pronotum faintly and nubilously paler; head large, four-fifths as wide as the prothorax, with large and conspicuous eyes, the apical impressions as in the preceding, the central puncture subobsolete; antenne rather short and thick, obscure, the two basal joints pale; prothorax large, a fourth wider than long, widest beyond the middle, the sides rounded, oblique and straight in basal half, the angles very obtuse, rounded; surface punctulate apically and broadly so at base, the basal impressions external and shallow; transverse impressions completely obsolete; apex very slightly sinuate, the median line fine but deep, not attaining the apex; elytra oblong, parallel, with feebly arcuate sides and rapidly very obtuse apex, not one-half longer than wide and only about a fourth wider than the prothorax; strie rather deeply impressed, but not notably coarse, the intervals evidently convex; puncture between apical third and fourth, adhering to the second stria as usual. Length 3.35 mm.; width 1.4 mm. New York (near the city). Differs from indistinctus Dej.,in its broader form, larger pro- thorax, with more arcuate anteriorly inflated sides, and in the somewhat thicker antennae, among other differential characters. 148 MeEmoIRs ON THE COLEOPTERA Tachistodes convergens n. sp.—Parallel, rather convex, polished and evenly rufo-testaceous, the head slightly more obscure, very moderate in size and scarcely two-thirds as wide as the prothorax, the eyes rather small, only slightly prominent; apical impressions as usual, the central puncture virtually obsolete; antenna rather long, unusually slender, obscure, paler basally; prothorax between a third and fourth wider than long, inflated beyond the middle and with rather strongly arcuate sides, the latter straight and unusually convergent thence to the base, the angles very obtuse, rather broadly rounded; transverse impressions wanting; surface very sparsely and feebly punctate apically, finely but more strongly basally, the latero-basal impressions rather small, feeble; median line deep, almost entire; apex unusually sinuate, with well-marked angles; elytra one-half longer than wide, only about a fourth wider than the prothorax, parallel, with moderately arcuate sides and circularly rounded apex; striae deeply impressed, with convex intervals. Length 3.65 mm.; width 1.35 mm. New York (Rock- away Beach, Long Island). This is a very distinct species in general habitus, inflated and strongly, basally narrowed prothorax, with sinuate apex and less obtuse elytral apex; it may be placed at the end of the series. PSEUDOMORFHIDAE Pseudomorpha Kirby Of castanea Csy., I have recently received four specimens from Utah, a little narrower than the original female type and slightly paler in color; they are all males, having a short and densely ciliate central line on the third and fourth ventral segments; the species is parallel but not so narrow as angustata Horn, from Arizona, and has a much larger head, with relatively smaller eyes. The following species is closely allied to excrucians Kby., but is larger and parallel: Pseudomorpha ruficollis n. sp—Broad, oblong, with parallel sides, convex and highly polished throughout, bright rufous, the elytra black, with the narrowly reflexed margins testaceous; head large, though only four-sevenths as wide as the prothorax, the eyes moderate, only slightly convex; surface with remote but rather strong punctures; antennez short, compressed and slender, only a fourth longer than the prothorax, testaceous; prothorax short and broad, about twice as wide as long, the sides converging throughout and evenly, moderately arcuate, widely reflexed and, like the elytral margins, with long distinct erect sete, deplanate about the basal angles, which are very broadly rounded; base a third wider than the broadly sinuate apex, the latter having narrowly rounded angles; surface nearly even, with fine and sparse but distinct punctures bearing erect hairs; scutellum very obtusely angulate behind; elytra four-sevenths longer than wide, scarcely as wide as the thoracic base, the sides parallel and nearly straight; apex abruptly, arcuately subtruncate, without trace of apical sinuses or scutellar stria; surface even, with sparse and rather coarse, subasperulate punctures, forming nine moderately definite series, but finer and confused medio- basally; tarsi not very long but simple, the anterior and middle with a few short coarse hairs beneath; abdomen finely, closely punctate subbasally, more sparsely and subserially toward the sides, the fourth and fifth segments each with a very AppitTions TO NortH AMERICAN COLEOPTERA 149 short, densely ciliated line centrally in the male. Length (@) 7.5 mm.; width 3-4mm. Louisiana (Covington),—Soltau. This species is undoubtedly closely allied to excrucians, but is much larger and parallel in form, not distinctly narrower posteriorly as notable in that species; the elytral punctures, although rather conspicuous, do not seem to be quite so coarse and, instead of two submarginal punctures at each side of the apex of the last ventral, there is here a series of four or five close-set punctures in that position; there is also no trace of a transverse line of setigerous punctures on the two penultimate segments, as related by Horn of excrucians, these transversely disposed punctures being fine, con- fused and not especially setigerous. In this genus there are six abdominal segments, the third and fourth of Horn being really the fourth and fifth. The length of excrucians, from Georgia, as given by Horn is 6.5 mm. STAFPHYLINIDE Staphylinus Linn. The broadly and asexually dilated anterior tarsi constitute one of the most remarkable characters of this genus, which includes the largest species of the family. The two following species are apparently undescribed as yet: Staphylinus quadraticeps n. sp.—Slender, moderately convex and shining and smoky-black throughout, the legs and abdominal apex not paler; head distinctly longer than wide, perfectly parallel, with straight sides and not very broadly rounded basal angles; surface coarsely and very densely punctate, the punctures separated by fine shining septa; antenne black, not very thick, the outer joints barely at all wider than long, even on the more compressed side; prothorax as long as wide, scarcely at all wider than the head, the sides parallel and straight; base broadly, circularly rounded, just visibly less than black, the apex truncate, with rather distinct blunt angles; punctures coarse and dense, just visibly sepa- rated, with a rather wide entire smooth median line; elytra but slightly shorter than wide, a little wider than the prothorax, the sides feebly flaring; punctures moderate and very dense, the surface subopaque; abdomen very nearly as wide as the elytra, finely, densely punctate and subopaque. Length (?) 13.0 mm.; width 2.75 mm. Florida (locality unrecorded). The upper surface has short, rather close and somewhat coarse pubescence, more erect and bristling along the sides and evenly dense and immaculate on the abdomen. This species may be placed near cinnamopterus, but differs in its entirely blackish color, still denser and stronger sculpture and entire absence of the trans- verse apical row of cilia observable in the latter. Staphylinus triplicans n. sp—Rather stout and somewhat fusiform, black, the legs pale, the femora black at base; pubescence in general very short and in- 150 MEMOIRS ON THE COLEOPTERA conspicuous; head about as long as wide, subtriangular, with rounded angles, the eyes large, feebly convex, at their own length from the base; surface even, with coarse and deep, separated punctures and a very short central smooth line; antenne black, about as long as the head, moderately thick; prothorax much wider than the head, barely wider than long, the sides parallel, broadly arcuate, broadly rounded into the rounded base, the apical angles right and evidently rounded; surface shining, coarsely, deeply and closely but discretely punctate, with a short median smooth line near the base; scutellum flat, acutely ogival, with a large, oval and densely velvetly-black spot; elytra distinctly wider than the prothorax, about as long as wide, parallel, with broadly arcuate sides, the surface evenly subeneo-blackish, moderately and densely punctate and finely subscabrous; abdomen at base nearly as wide as the elytra, feebly tapering, finely, closely punctulate and feebly subscabrous above, shining and more strongly, loosely punctate beneath, each segment with a feeble loose silvery pubescent spot near each side; above, each segment has an ogival silvery pubescent spot at the middle of the base and another, wider, basal spot of the same kind near each side, the three series separated by velvety-black basal areas. Length 15.0 mm.; width 3.8 mm. Maine (Eastbrook),—J. H. Emerton. This apparently very distinct species may be placed near mysticus Er., but is easily separated by the general sculpture and by the abdominal sculpture and vestiture. Euesthetus Grav. There are numerous species of this genus, many still undescribed ; the following is unusually distinct in coloration and general appear- ance: Euesthetus bicoloratus n. sp—Narrow, moderately convex, shining, rufo- piceous, the prothorax nearly black; head, abdomen above and beneath and about posterior half of the elytra, rufous; pubescence minute, sparse and incon- spicuous; head a little wider than the prothorax, deeply but not densely punctate, the eyes moderately large, convex and prominent; antennz barely longer than the head, slender, the club moderate; prothorax slightly wider than long, the sides subparallel in apical, oblique in basal, half; punctures moderate, rather deep and somewhat close-set; elytra distinctly transverse, with oblique sides, a fourth wider, the suture evidently shorter, than the prothorax; punctures moder- ate and loose antero-laterally, elsewhere obsolete; abdomen sparsely punctulate, the basal segments feebly, transversely impressed; legs slender. Length 1.2 mm.; width o.3 mm. Florida (near Indian River). This is a distinctly characterized species by its coloration and general structure. CLAVIGERID.E Adranes Lec. The following species is the smallest and especially the narrowest as yet known to me: Adranes angustus n. sp.—Narrow, convex, moderately ventricose, testaceous, shining, the pubescence short, coarse and rather sparse; head elongate, the part before the very small subbasal prominences parallel and quadrate, the sides behind AppITIONS TO NORTH AMERICAN COLEOPTERA 151 them oblique in basal third, the eyes wanting as in ce@cus; antennz short, a little longer than the head, the last joint parallel, gradually narrowing basally and about four times as long as wide; prothorax narrow, nearly two-fifths longer than wide, the sides rounded but subangulate near apical two-fifths, thence feebly converging and slightly arcuate to the base, more oblique and straight to apex; surface sparsely, shallowly punctate, convex, with a deep, post-central and slightly elongate fovea; elytra a third wider than long, with nearly straight oblique sides, about twice as wide as the prothorax, finely, sparsely punctulate; medio-apical tuft of very few hairs evident; abdomen a little longer than wide, oval, the large basal cavity somewhat prolonged medially, with rounded outline. Length 1.6 mm.; width 0.55 mm. Missouri (St. Louis). Differs from c@cus in its narrower form, shorter antenne, narrow and not regularly pentagonal prothorax, with the discal fovea less posterior, and in the finer and feebler punctuation. PTILIUDA Dilinium n. gen. Some suboval, convex, very pallid species, with the prothorax parallel and evenly arcuate at the sides, the surface with two fine subparallel incised longitudinal lines, the elytra long and narrowing behind, seem to necessitate a new genus, which may be allied somewhat to Millidium. The eyes are very small and the last palpal joint is enlarged and with an oblique appendage. The anterior and middle coxe are contiguous, the posterior rather widely separated and the abdomen has six segments, the first and last larger, subequal, the others very short, the fifth still shorter, extremely abbreviated. The following is the type: Dilinium rhodeanum.—Rather narrowly oblong-oval, convex, shining, pale flavo-testaceous, minutely, not very densely punctate and with very minute pubescence; head large, fully three-fourths as wide as the prothorax, the eyes small, prominent, basal and with a few convex facets; last palpal joint broad, oblong, with an oblique slender apical appendage; prothorax nearly one-half wider than long, the sides subparallel, rather strongly arcuate; surface at each side with a fine incised line at outer third, from just before the middle nearly to the base; scutellum large, rectilinearly triangular; elytra nearly one-half longer than wide, oval, with arcuate sides and rather rapidly obtuse apex, about a third wider than the prothorax. Length 0.55 mm.; width 0.25 mm. Rhode Island (Boston Neck). Numerous examples, very uniform throughout. Readily distinguishable by the ovoidal form, minute size, pale color, thoracic lines and many other characters. A very closely allied form, probably subspecific, occurs not rarely at St. Louis, Mo. Ptenidium Er. The species of this genus are moderately numerous and to be recognized at once by their rather broadly oval form and convex polished surface. The following is the smallest species known to me: 152 MEMOIRS ON THE COLEOPTERA Ptenidium parvulum n. sp.—Rather broadly oval, convex, smooth and polished, black, the antenne and legs pale, the elytra slightly piceous; punctures minute and very remote, each bearing a minute stiff erect hair; head large, three-fourths as wide as the prothorax, the eyes basal, moderate in size and with numerous facets; prothorax about one-half wider than long, parallel, with regularly arcuate sides, the surface convex, even and with two small rounded perforate punctures, near the base separated by about a fourth the total width; scutellum well de- veloped, equilatero-triangular; elytra about a fifth wider than the prothorax, oval, three-sevenths longer than wide, with arcuate sides, oblique posteriad, the apex narrow, not truncate. Length 0.65 mm.; width 0.33 mm. Mississippi (Vicksburg). Several specimens. The only species that I can find allied at all closely to this is one from Louisiana, bearing the name fovezcolle by Mr. Matthews, but this is much broader than parvulum, with the prothorax broader, subequal in width to the elytra and with the two fovee more widely separated. Nephanes Thoms. There are several American species of this genus, but the following seem to differ from others in a rather more broadly oblong outline: Nephanes puritanus n. sp.—Oblong, parallel, moderately convex, shining, but with rather strong but minute, subasperate punctures; color black above and beneath, the legs and antennz piceous; head large, convex, four-fifths as wide as the prothorax, the eyes basal, moderate and with numerous rather small facets; antenne about as long as the thoracic width; prothorax two-thirds wider than long, parallel, with evenly and strongly arcuate sides, the punctures close; scutellum equilatero-triangular; elytra only a fourth or fifth longer than wide, equal in width to the prothorax and three-fourths longer, the parallel sides only just visibly arcuate; apex rectilinearly truncate, punctures numerous, the vesti- ture very short. Length 0.4 mm.; width 0.18 mm. Rhode Island (Boston Neck). One specimen. A little shorter than a species named for me by Mr. Matthews as Nephanes titan, but similar in size, the elytra not quite so ab- breviated. Nephanes vicksburgensis n. sp.—Oblong, parallel, moderately convex, slightly shining, black, closely, asperulately punctate, subgranularly on the even pronotal surface; pubescence short, coarse, pale, subdecumbent and rather close; head nearly three-fourths as wide as the prothorax, the eyes moderate, with numerous rather small facets; antenne notably elongate, more than half as long as the body, very slender, the first two joints thickest, cylindric, the first somewhat the larger; prothorax three-fourths wider than long, the sides subparallel, dis- tinctly arcuate; apex but little narrower than the base; scutellum large, closely punctulate; elytra about a third longer than wide, rectilinearly parallel, slightly narrower than the prothorax, arcuately truncate at apex; punctures asperulate and close-set. Length 0.65 mm.; width 0.28 mm. Mississippi (Vicksburg). Much larger than the preceding, with longer antenne, broader prothorax and shorter elytra. AppITIons TO NORTH AMERICAN COLEOPTERA 153 Ptilium truncatum Csy., should also enter this genus; it is decidedly broader than either of the above species, black, with short truncate rufescent elytra. Ptiliodina n. gen. Body pale in color, convex and shining, the surface coarsely micro-reticulate and sparsely punctate, very finely and feebly, more coarsely on the elytra. Eyes very small, basal; antenna moderate, the first two subcylindric joints notably thick. Prothorax bitrun- cate, parallel, the base and apex subequal, the hind angles not produced. Scutellum moderate, subequilatero-triangular; elytra oblong-suboval, with arcuate sides and truncate apex. Anterior and middle coxze subcontiguous, the posterior widely separated, not laminate. Sterna extending to the sides of the body. Abdomen with six segments, the first the largest. The type is the following: Ptiliodina ochracea n. sp.—Oblong, convex, shining and pale ochraceo-testa- ceous throughout; head rather more than two-thirds as wide as the prothorax, the latter about two-thirds wider than long; elytra but little longer than wide, the sides parallel and arcuate, at the middle distinctly wider than the prothorax, the apex truncate; pygidium exposed and steeply declivous. Length 0.65 mm.; width 0.23 mm. Rhode Island (Boston Neck). This is a very distinctly characterized species, moderately abundant and rather constant. The genus may be placed near Ptinellodes, but differs in having no vestige of the Acratrichis facies seen in the latter. Ptiliopycna n. gen. This genus seems to be allied to the last, but the body is very much stouter, parallel and with very minute sparse punctures, the integuments with a system of extremely minute feeble transverse strigilation. The eyes are moderate and coarsely faceted, the antenne II-jointed, with a 2-jointed club. The prothorax is noticeably inflated toward base but with simple basal angles, the scutellum large and rectilinearly triangular and the elytra are rectilinearly truncate at tip, covering and overhanging the basal part of the rapidly declivous pygidium. The pubescence is fine, subdecumbent, short and sparse. Anterior coxee contiguous, the posterior rather well separated and laminate. The metasternum is large but does not extend quite to the sides of the body. The abdomen has six segments, the first large, as long as the next four, which are very short, the sixth longer. The type is the following: 154 MEMOIRS ON THE COLEOPTERA Ptiliopycna quadrata n. sp.—Parallel, convex, shining and black, the under surface more piceous, the abdomen rufescent, the legs pale flavate; head large, rather more than three-fourths as wide as the prothorax, the slender antenne with the usual two large cylindric basal joints, extending well behind the thoracic base; prothorax two-thirds wider than long, the sides arcuate, less so and more oblique anteriorly; apex distinctly narrower than the base, the surface evenly convex; elytra fully as long as wide, equal in width to the prothorax, the sides parallel and feebly arcuate. Length 0.55 mm.; width 0.32 mm. Michigan (Detroit) ,—Schwarz. This species will be recognized readily by the broad and sub- quadrate convex form, very minute and feeble sparse punctulation, 2-jointed antennal club and laminate hind coxe. Ptilium Er. Pt. fungicola Csy., seems to be a true Ptilium, but the very minute szlcatwm, the type of which was unfortunately shaken from the paper point and irretrievably lost, should quite probably form the type of a distinct genus; the original description and figure will probably serve for identification, if ever recovered. The following are a few species as yet undescribed: Ptilium austinianum n. sp.—Rather narrow, parallel, convex, feebly shining, blackish-piceous, the punctures fine, asperulate and rather close, the elytra, micro-reticulate, the pubescence short, subdecumbent; head large, more than three-fourths as wide as the prothorax, the eyes moderate, slightly convex and with numerous moderate facets; antenne extending but little beyond the pro- thorax, black, the two basal joints pale; prothorax not quite twice as wide as long, the sides subparallel, moderately arcuate; scutellum moderate, equilateral; elytra not quite one-half longer than wide, parallel, with barely arcuate sides, equal in width to the prothorax, the apex of each rather evenly rounded. Length 0.45 mm.; width 0.18 mm. Texas (Austin). Two specimens. Easily recognizable by the general form, coloration of the antenne, sculpture and other features. Ptilium curticolle n. sp.—Elongate-suboval, convex, shining, brownish-testa- ceous in color, the punctures fine and subasperate, the pubescence as in the two preceding; head large, fully three-fourths as wide as the prothorax, the eyes small; antenna piceous, with paler two basal joints, extending far beyond the thoracic base, the club normal; prothorax about twice as wide as long, the strongly arcuate sides converging and arcuate anteriad; scutellum moderate, exactly equilateral; elytra rather long, one-half longer than wide, parallel, with somewhat arcuate sides and broadly rounded apex, about as wide as the prothorax. Length 0.42 mm.; width 0.18 mm. Rhode Island (Boston Neck). Separable from the preceding by slightly smaller size, pale color, longer elytra and slightly longer antenne. The two following species seem to belong to this genus but may possibly have to be generically separated at some future time: ADDITIONS TO NORTH AMERICAN COLEOPTERA 155 Ptilium shastanum n. sp.—Oblong, parallel, convex and polished, flavo- testaceous; head short, somewhat more than three-fourths as wide as the pro- thorax, rather smooth; antenne but little longer than the head and prothorax, slender, very pale flavate, with a moderate loose 3-jointed club; prothorax fully four-fifths wider than long, widest slightly behind the middle, the sides broadly arcuate; surface very smooth and shining, minutely, rather sparsely punctulate; elytra not quite as wide as the prothorax, nearly one-half longer than wide, parallel, with feebly arcuate sides and truncate apex, shining, sparsely, pallidly pubescent and with rather strong and sparse, asperulate punctures; abdominal apex exposed and rapidly declivous. Length 0.65 mm.; width 0.35 mm. Cali- fornia (Siskiyou Co.). One specimen. Identifiable by the pale color, shining surface and sparse punc- tures. Ptilium franciscanum n. sp.—Parallel though not rectilinearly so, convex, piceous in color, rather shining; head short, three-fourths as wide as the pro- thorax, the antenne extending well behind the thoracic base, flavate, very slender, with a loose, thicker and piceous club, the erect sete long and bristling; prothorax three-fourths wider than long, the parallel sides evenly and distinctly arcuate; punctures minute and sparse, the pubescence pale and sparse, relatively rather long; elytra oblong-oval, equal in width to the prothorax, scarcely over a third longer than wide, the sides parallel and evenly arcuate, the apex truncate; surface with distinct pallid pubescence and fine and loose, subasperate punctures; abdominal apex behind the elytra rapidly declivous; under surface pale flavate throughout. Length 0.7 mm.; width 0.4 mm. California (Sta. Cruz Mts.). One specimen, probably taken by Mr. Koebele many years ago. This distinct species may be recognized easily by the oblong and convex form, rather smooth surface and arcuate sides of the pro- thorax and elytra. It probably does not pertain strictly to Ptilium. The species which I described as Acratrichis (Trichopteryx) longipennis,seems to be quite distinct and valid; it is still repre- sented by three examples, but the type of Trichopteryx fungina is lost, so that I have replaced it by a species occurring in Rhode Island, which seems to fulfill the terms of the description reasonably well. Acratrichis radicicola—not radicola as originally published— is represented by the type, now having the entire head and prothorax broken off and lost, but some specimens at hand from Beatty, Penn., seem to be virtually typical. COcCINELLIDA Hippodamia De}. The form named caseyi by Mr. Johnson, alluded to in Mem. Col., II, is nothing more than a subspecies of mulsanti Lec.; it occurs abundantly in Washington State, Oregon and Utah. That form mentioned by the author as being a modification of convergens Guér., so abundant in Washington State, and having the post- 156 MEMOIRS ON THE COLEOPTERA scutellar spots united with the scutellar dash to form a 3-pointed star, may be defined as follows: Hippodamia convergens ssp. pugetana nov.—Almost exactly resembling convergens in form, size and color, but differing in the extent and disposition of the black marking, which is a little heavier as a rule than in convergens, the two post-medial points frequently being transversely united and the two post-scutellar spots joined with the scutellar spot. Length 4.6-6.0 mm.; width 2.7-4.0 mm. Washington State (Fairfield). Nineteen specimens. In convergens there are three small rounded spots before and three behind the middle of each elytron, forming a triangle in each case; the spots are always widely isolated among themselves, that is, at least in every case of a very large series from all parts of the country. Obliqua and politissima of the Pacific coast are simply varieties, the former without anterior or subapical spots on the elytra, but with the two post-medial spots sometimes loosely united transversally; the latter is wholly spotless. Utfeana is, I think, a distinct though closely allied species, rather than a subspecies; the markings are as in pugetana but heavier, the pronotum never with median white oblique spots and having very narrow white margins. The following may be regarded as a subspecies of wteana: Hippodamia uteana ssp. quadraria nov.—Form, color and fine close punctures nearly as in wfeana, but rather more briefly oval; pronotum solidly black, with very fine white side-margins throughout; elytra without trace of the small black scutellar spot, each elytron with two circular and clearly defined subbasal spots of black, and one minute and inconstant externally near basal fourth, also a heavy transverse oblique spot behind the middle and one oval and subapical. Length 5.0 mm.; width 3.4mm. Canada (Edmonton, Alberta),—Carr. One specimen. The entire absence of a black spot at the scutellum, with the other maculation as mentioned, decidedly heavy, forms a rather notable character. Hippodamia americana ssp. fontinalis nov.—Form and markings nearly as in americana, except that the long sutural vitta of that species is replaced by a very short, subapically dilated dash, not extending quite to basal third; pronotum polished, very minutely, loosely punctulate, with two heavy oblique central pale lines and an apical and lateral margin, the latter dilated but little basally, of yellow; elytra opaculate, largely rufous, the broad black median vitta on each ending in slight dilatation at two-thirds, and also with a heavy oblique black spot near the apex. Length 5.0 mm.; width 2.85 mm. New Mexico (Jemez Springs), —Woodgate. Quite readily distinguishable from americana by the very short, rather wide sutural vitta; it is closely allied to crotchi Csy., from California, and it seems probable that the two, together with complex Csy., may form a true species, distinct from spuria and americana. ADDITIONS TO NORTH AMERICAN COLEOPTERA 157 Hippodamia sinuata ssp. albertana nov.—Form, coloration and maculation throughout almost as in simuata, but differing in the solid black area of the pronotum, which in sinuata is minutely, angularly incised at apex, with heavy diverging white central lines and no trace of medial basal pale marking; in albertana the black pronotal area is broadly and feebly sinuate medially at apex, wholly devoid of white marking at the middle and witha small white ante-scutellar marginal spot at base; the oblique apical part of the medial vitta of each elytron is less prolonged and is not so abruptly demarcated.as in sinuata, the black sutural vitta even longer, gradually evanescent close to the hind angles. Length 5.25 mm.; width 3.0mm. Canada (Edmonton, Alberta),—Carr. The true simuata is represented in my collection from Durango, Mexico. The California form, which I named frivittata, is much smaller, has subbasally dilated sutural vitta and differs in several other ways, though doubtless not more than a subspecies of sinuata. Neoharmonia Csy. The name notulata of Mulsant, is really a synonym of venusta Mels.; but there is a form entirely black, the apical thoracic angles obliquely pale, as also a slightly post-median fascia from inner third of each elytron to the side margin, having two angulate anterior projections; this varietal form was unnamed and I have preserved the name notzlata in this related form; the following is another: Neoharmonia centralis subsp. nov.—Much larger than notulata, broadly and evenlv oval, the head black; pronotum black, the sides yellow, dilated anteriorly and the apex also pale, also a minute pale point on the median line near basal third; elytra deep black, each with a central 3-pointed star, its sides all sinuate; legs black; epipleura pale, with black outer margins. Length 6.0-6.2 mm.; width 4.4 mm. Illinois (about 30 miles south of St. Louis). Three specimens, exhibiting no variability. This form is recorded as a subspecies, as in the case of the forms of Olla and Anisocalvia given below, but I have no very clear idea of the true relationship and it can only be said that each form is extremely constant throughout numerous individuals. The proper term to be used is probably not subspecies or variety, but ne of the elemen‘s of a polymorphic species, although the cause or nature of this polymorphism is entirely unknown to me. Olla Csy. The form which I described as minuta is given by Mr. Leng as a synonym of abdominalis, but it has no such status at all, being a true subspecies to say the least; in fact applying the criteria derived from other Coleoptera, it could be nothing less than a distinct species. The following is another: T. L. Casey, Mem. Col. XI, Mar. 1924.—11 158 MEMOIRS ON THE COLEOPTERA Olla abdominalis ssp. arizone nov.—Form and general coloration nearly as in abdominalis; pale straw-yellow; pronotum with seven black spots, the two outer small, widely isolated and circular; elytra with the three subbasal spots of ‘abdominalis and, from just before the middle of each to apical third or fourth, a large solid black spot, broadly oval in outline behind and transversely sinuate in front, also in line with its anterior margin a transverse isolated spot near but not quite attaining the lateral margin, also with a very minute imperfect spot at apical fourth and outer fifth, sometimes wholly wanting. Length 5.2-5.3 mm.; width 4.3-4.4 mm. Arizona (near Tugson),—Tucker. Two specimens. The constancy in marking of abdominalis through very extended series, from Missouri to Central Mexico and the Pacific coast, is indeed remarkable, showing that these various forms attached now to a few type species of this and neighboring genera, have not originated from variation in the ordinary sense. Cleis Muls. The following form is closely related to picta but differs in some details: Cleis picta ssp. nubilata nov.—Almost similar in form, size and general colora- tion to picta, the two black vitte of the head disintegrated; pronotum similar in form and in its polished lustre, having four medial spots forming a V-shaped pattern and, just beyond this, a smaller and oblique detached V; besides these markings of deep black, there are only three or four minute points in the nubilous lateral field; the general maculation of the elytra is nearly as in picta, but the darker regions are so pallid as to be barely traceable. Length 4.5 mm.; width 3.0mm. Mexico (Colonia Garcia, Chihuahua),—Townsend. I have seen only a single specimen of this variation; it is very much larger than minor, from the Pacific coastal regions, but all these have very nearly the same form of maculation seen in picta. Anisocalvia Cr. The following six forms can be attached to quatuordecimguttata in some indefinite subordinate relationship, probably of a poly- morphic nature. Anisocalvia lacustris nov.—Oval, strongly and deeply punctate, the pronotum more finely; color deep black, the front pale at each side; pronotum narrowly margined at the sides and apex with straw-yellow, the black median part divided longitudinally by a fine, basally interrupted pale line; elytra uniform deep black, the fine reflexed margins pale, also a small transversely suboval discal spot on each at three-fifths and inner third; under surface black, the abdomen broadly pale peripherally, the legs very pale. Length 4.5-5.2 mm.; width 3.3-3.9 mm. Michigan (Marquette),—Sherman. Differs very much from cardisce in the two very sharply defined subsutural spots behind the middle of the elytra. AppITIONS TO NORTH AMERICAN COLEOPTERA 159 Anisocalvia bicordifera nov.—Broadly oval, deep black, shining, the sculpture not so strong or dense as in the preceding; head uniformly black; pronotum deeply impressed along the sides of the disk and also feebly toward base near outer fifth; deep black, witha very fine testaceous margin near the anterior angles only, without other pale marking; elytra very broadly rounded, deep black, without pale edges, each with a large and sharply defined cordate discal yellow spot from before the middle to apical third, subtangent to the suture and extending four-sevenths to the sides; under surface and legs deep black, the inner margin of the epipleura pale, the tarsi also rather pallid. Length:5.35 mm.; width 4.0 mm. New York (Lake George),—Prof. J. F. Kemp. This is a very obviously distinct form, apparently not at all closely related to the preceding and possibly of specific value. Anisocalvia vancouveri nov.—Form and coloration nearly as in Jacustris, but a little larger and with the head black, very finely margined with pale tint; prothorax rather more rounded at the sides than in /acustris, and without the even transverse pale apex angularly prolonged posteriorly as in that form, but with the apex black, pale toward the sides, the median line narrowly pale from behind the middle to the apical margin; elytra black, with the two pale eye-like spots as in /acustris, though a little larger, but with the fine reflexed margin pale only toward apex, and not throughout the length as it is in lacustris; under surface and legs nearly as in /acustris. Length 5.25 mm.; width 4.2mm. British Columbia. This form can be considered as a variety of /acustris, and evidently not of the same taxonomic value as that form, bicordifera, post- plagiata, and perhaps one or two others. The following is related closely to lacustris and is of nearly the same taxonomic value as the latter: Anisocalvia quadrisignata nov.—Broadly oval, shining, the punctures rather finer than usual but of the same character; head very pale, the basal margin of the front black; pronotum black, margined throughout, except at base, with yellow, which is prolonged on the median line to the base, sometimes interrupted subbasally, the yellow margin dilated in a rounded area at base; elytra deep black, the fine reflexed margin pale, less so medially, each with a clearly defined small rounded spot tangent to the base at about inner third, and a slightly larger evenly circular spot at two-thirds near the suture; under surface black, pale peripherally, the legs wholly pale. Length 4.7-5.0 mm.; width 3.3-3.7 mm. Lake Superior (Marquette). Five very uniform specimens. Differs from lacustris and vancouvert primarily in the basal rounded spot of each elytron, of which there is no trace in those forms. Anisocalvia postplagiata nov.—Form rather less broadly oval, shining, with rather stronger punctuation; head as in the preceding; pronotum also as in quadrisignata almost throughout; elytra notably different, with pale whitish spots, one at base as in the preceding, three arranged transversely near basal third, of which the innermost is more minute and sometimes almost obsolete; from just behind the middle very nearly to the apex and from near the suture to near the outer margin, there is a large subtriangular pale area, sinuate medially 160 MEMOIRS ON THE COLEOPTERA at its anterior margin and inclosing a narrow black triangle just outside of its centre; reflexed margin pale, sometimes black medially; under surface and legs as in the preceding. Length 4.7-5.4 mm.; width 3.65-3.85 mm. Lake Superior (Marquette). Three specimens. The three cotypes of this form are virtually constant in every way and very strikingly different in ornamentation from any other development known to me. Anisocalvia uniformis nov.—Broadly oval, shining, the elytral punctures well separated but unusually strong; head black throughout; prothorax with the sides unusually arcuate, deep black, with pale testaceous margins except at base, angularly prolonged medially to behind the middle and with a small spot at the middle of the base, the pale side margins not at all dilated at base; elytra uniform black, without any form of maculation, the reflexed side margins unusually widely pale throughout the length; under surface and legs deep black, the epipleura pale. Length5.35mm.; width 4.0mm. New York (Adirondack Mts.),—Kemp. This is rather an isolated form that has been labeled cardisce Rand., in my collection for many years, but, on studying the description of that form more carefully, I find that the lateral pale margin of the pronotum is dilated at base and that each elytron has a pale spot at base and three along the lateral margin, and that there are also three spots disposed in triangle on the disk. In obliqua Rand., the elytra are black, each with an oblique testaceous spot. I have a specimen, also taken by Prof. Kemp and labeled ‘‘ Lake George, Adirondacks,’ which seems to represent this form. There is on each elytron a slightly oblique reniform vellowish spot, nearer the suture than the sides, rather before than behind the middle of the length and with its outline somewhat more nubilous than usual. The forms similis Rand., of which I have a good series from Marquette, taken by Sherman, and victoriana Csy., are both closely homologous with the true guatuordecimguttata, and they should all be considered as merely varietally different stages of the same | modification, whatever this may prove to be taxonomically. Neomysia Csy. The following species is related to randalli, described from Lake Superior. It is larger, much more broadly rounded and still more convex: Neomysia oregona n. sp.—Broadly rounded, very strongly convex, polished and very minutely, loosely punctulate; head and oral organs piceous to blackish, the eyes well developed, transverse, with a small feeble sinus at the middle of the apical margin; antenne gradually enlarged distally; prothorax with rounded ADDITIONS TO NORTH AMERICAN COLEOPTERA 161 and broadly, shallowly reflexed sides, brownish-testaceous, with a large trapezoidal area solidly black and about half the total width, the pale parts immaculate; elytra widest a little before the middle, two-thirds wider than the prothorax, pale brownish-testaceous, with nubilous darker markings—a narrow vitta from base to behind the middle near the sides, another similarly narrow vitta from near basal to apical third near outer fourth, another narrow somewhat sigmoid vitta along the median line from the middle to near apical seventh, and a nubilous, broadly vittiform area at about inner fourth, from base almost to middle, with a small terminal macula; sides feebly explanato-reflexed these, as also the suture not maculate; under surface black, with broad pale epipleura, the legs wholly dark brown. Length 7.5 mm.; width 5.8 mm. Oregon (Bull Run, Clackamas Co.),—Mrs. R. R. Kermack. This is a species which I think could not be confounded with any other; it differs from randalli in its paler and less sharply defined dark markings, pale and not black sutural and external edges, absence of the tripartite series of dark areas along the middle of the elytra, entire lack of sublateral discal dark pronota! spot, and still finer and feebler punctuation. Exochomus Redt. Many of the described forms in this genus have a mutual taxo- nomic status analogous to those of Anzsocalvia in all probability, but they are similarly very constant individually in their various patterns of ornamentation, and it is therefore desirable that separate names should be assigned them. There are some type forms, however, which should be given the full specific status in the present genus; californicus, with desertorum, ovoideus. parvicollis and histrio, is one of these species, marginipennis, with childrenz, latiusculus and several others, another, and the Cuban venustulus still another. The following is one of these strange allotropes: Exochomus ixtlensis nov.—Very broadly rounded, almost circular, polished, very convex and almost sculptureless, black, the anterior thoracic angles finely margined with pallid tint; elytra clear and pale reddish-yellow, with a wide transverse black fascia, its hind margin at the middle rather widely separated from the sides and with its anterior margin angularly extended but not quite to base on the suture, and, on each elytron at the middle of its width, also with a transversely oval large black discal spot, rather distant from apex and sub- equidistant from suture and margin; legs and under surface black, the almost vertically descending deep epipleura very pale. Length 2.55-2.75 mm.; width 2.0-2.2 mm. Mexico (Ixtla, Morilos),—Wickham. This form may be placed next to fasciatus, but it is much more broadly oval and differs in several other respects. 162 MEMOIRS ON THE COLEOPTERA Hyperaspis Chev. The two following species cannot be identified with any others in my collection and, so far as I am able to judge, are as yet un- described : Hyperaspis tuckeri n. sp.—Oblong-suboval, convex and polished, the punctures not close, very small and inconspicuous; head well developed, wholly pale yellow in the type; pronotum deep black, evenly and rather widely margined with yellow at apex, broadly yellow at the sides, the inner margin of the pale area parallel; elytra deep black, each with a large rufous spot from basal fourth to apical third and from inner two-fifths to outer seventh, without further maculation; under surface black, the anterior and middle legs pale, the posterior nearly black. Length 2.8 mm.; width 2.0mm. Arizona (near Tugson),—J. F. Tucker. This species is of an oblong, subparallel form, and may be placed near Jengi Schf.; it however has much less arcuate sides and quite different elytral maculation. Hyperaspis uniformis n. sp.—Oval, convex, polished, minutely, sparsely and inconspicuously punctulate; head testaceous in both sexes, moderately developed; prothorax between two and three times as wide as long, the sides converging and broadly arcuate; surface black, with very narrow lateral marginal pale area (2), or broadly testaceous in about lateral fourth, with narrow apical pale margin (<7); elytra completely black, without trace of paler spots in either sex; in the male type the under surface of the hind body is black, the abdomen broadly margined with testaceous, all the legs rather pale; in the female the abdomen is wholly black and the hind legs are also black. Length 2.6-3.1 mm.; width 1.7-2.1 mm. North Carolina (Southern Pines),—Manee. At present it would seem best to place this species near postica and elliptica. The three following species have a single discal spot on each elytron and may be placed near bznotata: Hyperaspis pinorum n. sp.—Oval, convex, polished, black and with unusually strong but loose punctuation; head fully half as wide as the thoracic base, eyes well developed and generally greenish in reflection, the punctures finer and closer; front entirely flavate; prothorax between two and three times as wide as long, with strongly converging and nearly straight sides from above, black, the sides in lateral sixth or seventh and the entire apex flavate, the lateral area parallel; elytra barely (co) or considerably (9) longer than wide, very broadly rounded at apex, at the middle evidently wider than the prothorax, each with a very moderate rounded rufous spot from barely before to a little behind the middle ~ and from scarcely within to sensibly without the median line; under surface black, the legs and abdominal margin throughout pale. Length 2.3-2.6 mm.; width 1.7-1.85 mm. North Carolina (Southern Pines),—Manee. The four specimens at hand are all alike in coloration throughout, and in all probability are males; it however differs from the male of binotata in the much more extended pale areas at sides and apex of the pronotum, also in its less broadly rounded outline. ADDITIONS TO NORTH AMERICAN COLEOPTERA 163 Hyperaspis conviva n. sp.—Larger than the preceding, oval, convex, black and shining, the punctures of the upper surface a little finer, somewhat less distinct and not quite so conspicuous; entire upper surface in the type deep black, except a rufous discal spot on each elytron, transverse in form and differing in position from that of pinorum, lying between basal third and the middle and inner two-fifths and outer fifth of the width; head and prothorax formed nearly as in the preceding, the elytra slightly longer and more evenly elliptic; under surface and legs black, the abdomen with a moderate flavate border, obsolete at the middle of the apex. Length 3.1 mm.; width 2.15 mm. North Carolina (Southern Pines),—Manee. The single type of this species differs from bznotata in the more elongate-oval outline and especially in the transverse red elytral spots, situated more anteriad. Hyperaspis maneei n. sp.—Elongate, suboblong-oval, convex, polished, deep black throughout and finely, loosely and inconspicuously punctate, the elytra each with a single large rufous submedial area, from basal fifth to little behind the middle and from inner two-sevenths to the lateral margin; head more than half as wide as the prothorax, the latter of unusual outline, two and a third times as wide as long, the sides moderately converging and slightly arcuate, not quite in continuous curvature with the elytral sides, the apical angles produced, slightly blunt; elytra nearly a fourth longer than wide, evenly oval, obtuse at apex; entire under surface and legs black. Length 3.25 mm.; width 2.2 mm. North Carolina (Southern Pines),—Manee. The single type of this species is more elongate-oval than in the preceding and with the sides of the prothorax less converging, the apical angles more prominent apically; it differs also very much in the form and extent of the spot on each elytron. Hyperaspis triplicans n. sp.—Broadly oval, very strongly convex, polished and deep black, the upper surface with fine and sparse but rather deep punctures; head distinctly less than half as wide as the thoracic base, black, with a nubilous yellow spot at the middle of the front in the type; prothorax between two and three times as wide as long, of the usual form, with strongly converging and very feebly arcuate sides, black, the sides in about lateral ninth or tenth testaceous, with the inner margin of this pale area bisinuate, the apex not pale; elytra obtusely rounded, distinctly wider than the prothorax, barely visibly longer than wide, each with three very moderate rounded testaceous spots, one slightly the smallest and at the margin at basal third, another very slightly before basal third, just visibly within the median line and the third at four-fifths and outer third; under surface and legs black or blackish, the tibia and tarsi pale. Length 2.7 mm.; width 1.85 mm. North Carolina (Southern Pines),—Manee. The single type is different from anything hitherto known to me, but the species may follow notulata in the list, the arrangement of the three elytral spots being almost similar, but, in that species, there is a small humeral spot, traceless here. The following is closely allied: : Hyperaspis triplicans ssp. microsticta nov.—Smaller and more narrowly oval, deep polished black, sparsely and even more minutely and inconspicuously punc- 164 MEMOIRS ON THE COLEOPTERA tate than the preceding; head more piceous-black, narrower; prothorax not so wide, similar in form and coloration, except that the marginal pale area is still narrower, and distinctly narrower at base than apex, with its inner margin more nearly even; elytra obtusely oval, the three spots on each at the same position but smaller, the two anterior minute and difficult to distinguish; under surface black, the legs picescent. Length 1.85 mm.; width 1.2 mm. Locality and collector as before. I cannot at present determine the true relationship between triplicans and microsticta and so give them the suggested status; ' from certain sexual chardcters observed elsewhere, it would seem that, if not specifically different, microsticta should be the female, but it is smaller and narrower than the type of triplicans; its elytral spots are extremely small and not distinct as they are in ¢riplicans. Hyperaspis carolina n. sp.—Shorter and relatively broader, very convex, obtusely oval and loosely punctulate; head only moderately wide, testaceous in the type, with greenish eyes; prothorax between two and three times as wide as long, with very converging sides, entirely black, except the narrow side-margins, which are pale and gradually narrowing, obsolete in basal fourth; elytra barely visibly longer than wide, very obtuse, with moderately arcuate sides, each with a very small posterior discal spot as in the two preceding and one, more anterior, at the margin and irregular in form and but little before the middle, also with a very minute, feeble and nubilous spot near the basal margin at inner fourth; discal spot of the two preceding wholly wanting; under surface piceous-black, the tibiz and tarsi pale. Length 2.3 mm.; width 1.65 mm. North Carolina (Southern Pines),—Manee. The type is probably a male and represents a species coming near the two preceding, but differing in the incomplete pale thoracic margins, absence of medio-discal elytral spot and presence of one very near the scutellum, untraceable in the others. It seems probable that this is a separate species. Hyperaspis insolens n. sp.—Very evenly and obtusely oval, shining, deep black, finely but strongly, closely punctate, the elytra rather more feebly and much less closely, the scutellum very finely but unusually closely; head in the type not quite half as wide as the prothorax, the front piceous, with a yellow vitta at each side; prothorax nearly three times as wide as long, the sides very oblique and feebly arcuate; surface wholly black (co), except a very fine lateral vitta near, but not quite at, the margin and not quite extending to apex or base; elytra evenly and obtusely oval, nearly a fifth longer than wide, each with a small circular rufous spot, the centre of which is very slightly before the middle and about on the median line; under surface, legs, and epipleura deep black. Length 3.2 mm.; width 2.3 mm. Michigan (Grayling, near Bay City),—C. V. Piper. One male specimen. This is a distinctly isolated species, narrower than binotata and with different sculpture and maculation of the anterior parts in the male. The following is an isolated species among those here described, but it may be placed near the Utah szgnzficans: AppDITIONS TO NORTH AMERICAN COLEOPTERA 165 Hyperaspis binaria n. sp.—Oval, polished, black, finely, sparsely and sub- obsoletely punctulate; head and prothorax moderate, wholly deep black in the type, the thoracic sides strongly oblique and very feebly arcuate; elytra but just visibly longer than wide, at the middle of the strongly arcuate sides about a fourth wider than the prothorax, each with a somewhat nubilously defined small reddish spot, at about the middle and adjoining the side margin, the spot feebly subdivided longitudinally by a feeble line; under surface and legs black, the tibie and tarsi paler, piceous, the epipleura pale below the marginal spot. Length 2.4 mm.; width 1.75 mm. North Carolina (Southern Pines),—Manee. The single type is probably a female. The following species may be placed near proba, but differs very much in having a marginal spot of peculiar form. Hyperaspis invertens n. sp.—Broadly, obtusely oval, polished, black, very minutely and sparsely punctulate, more closely on the anterior parts; head well developed, distinctly more than half as wide as the prothorax, wholly black in the type; prothorax between two and three times as wide as long, the oblique sides nearly straight, black, abruptly yellow in lateral fifth, the inner margin of the pale area arcuate; elytra barely longer than wide, each with a marginal yellow spot from the humerus to slightly behind the middle, like an inverted comma in form, dilated behind, gradually finely attenuate anteriad, also with three other rounded yellow spots, the centres of which are at a third and inner third, four-fifths and inner third and four-fifths near the margin, this spot attaining the lateral edge and narrower and more oval than the others; under surface black, the legs in great part black. Length 2.8 mm.; width 1.85 mm. Mexico (Gonzales Junc., Guanajuato),—Wickham. This is a distinct species, but might be placed near proba for the present; the sex of the type is probably female. The five following species belong to the undulata section of the genus, but in the first the sides of the elytra have three separate spots: Hyperaspis separata n. sp.—Oval, strongly convex, black, rather shining, with moderately distant and rather evident punctures, extremely minute on the anterior parts, larger on the elytra; head entirely black in the type, more than half as wide as the prothorax, the latter between two and three times as wide as long, the feebly arcuate oblique sides much shorter than the median line, having a yellow area at each side, parallel in form and less than a tenth the total width; elytra oval, distinctly longer than wide, not very obtuse and evenly rounded behind, each with two small yellowish spots on the side-margin, one a narrow streak from the base for nearly one-third, the other an internally rounded, mar- ginally truncated spot at about the middle; there are also two moderate rounded discal spots, very nearly on the median line, one near basal third, the other near the apex; under surface black, the legs piceous. Length 2.25 mm.; width 1.6 mm. Massachusetts (Natick),—Frost. One specimen. May be placed next to Jugubris, but differs in‘its polished and not alutaceous pronotum, rounded and not elongate-oval discal elytral spots and two widely separated marginal spots, these being united and forming a slender yellow margin in nearly basal three- 166 MEMOIRS ON THE COLEOPTERA fourths in lugubris, of which I have a male specimen taken at Tyngsboro, Mass., by Blanchard. The type of separata is doubtless the female, but this could not account for such marked divergence in elytral maculation; it is much smaller than my single lugubris. In octavia Csy., which occurs from Vicksburg, Miss., to Framing- ham, Mass., there is the same arrangement of the small elytral spots as in separata, but there the basal spot at the sides is short and broad, the punctures stronger and the legs black, with very pale tibiz and tarsi. Hyperaspis balsasia n. sp.—Small, suboblong-oval, moderately vaulted, pol- ished, black, finely, sparsely punctate; head nearly three-fourths as wide as the prothorax, which is but little more than twice as wide as long, with the sides but slightly converging, broadly arcuate and nearly four-fifths as long as the median line, both deep black, without paler marking; elytra subquadrate, the sides feebly arcuate, rapidly and obtusely rounded at apex; discal rounded whitish spot just before the middle and conspicuous, the outer whitish margin rather wide, entire, turned rapidly inward apically, increasing but little in width very nearly to the sutural margin, finely separated from the apex, its inner edge bisinuate, the posterior sinus the more strongly though obtusely angulate; under surface blackish, the epipleura yellow; legs piceous. Length 1.65 mm.; width 1.1mm. Mexico (Rio Balsas, Guerrero)—Wickham. The single specimen, because of its lack of anterior maculation, would seem to be the female; it is one of the smallest in my collec- tion at present, excepting sexualis. Of bensonica Csy., I have recently received a specimen, apparently female, but materially smaller than the male type, taken by Tucker, near Tug¢son. The following seems to belong to this section, but has subnubilous lateral pale areas and less oval outline: Hyperaspis nubilatus n. sp.—Parallel and subquadrate, with rapidly trans- versely rounded and extremely obtuse apex, shining, piceous-black and very minutely, sparsely and indistinctly punctulate, the head two-thirds as wide as the prothorax, black in the type, with the eyes subprominent from above; pro- thorax two and one-half times as wide as long, with very moderately oblique and slightly arcuate sides, three-fourths as long as the median line, the side-margins narrowly and subequally pale, the apex not paler; elytra as wide as long, quadrate, with feebly arcuate parallel sides, the flanks nubilously and faintly pallid in parallel area in about basal two-thirds; under surface piceous, the epipleura and legs brown. Length 2.0 mm.; width 1.4 mm. North Carolina (Southern Pines),—Manee. This is a notably isolated species, of which the following seems to be a rather close analogue, however. Hyperaspis asphaltina n. sp.—Male oblong, parallel, very rapidly and obtusely, transversely arcuate at apex, shining, deep black, finely, sparsely and incon- spicuously punctulate; head nearly three-fourths as wide as the prothorax, with ADDITIONS TO NORTH AMERICAN COLEOPTERA 167 notably prominent eyes viewed dorsally, dull rufous, gradually black basally; prothorax between two and three times as wide as_long, the moderately oblique and broadly arcuate sides distinctly shorter than the median line; surface with narrow and parallel, yellow side-margins in the type, the apex not paler; elytra a fifth or sixth longer than wide, the parallel sides nearly straight; surface deep black, without trace of paler maculation at any part. Female distinctly oval, with arcuate sides and broadly rounded apex; head scarcely two-thirds as wide as the prothorax, wholly black, the eyes not so prominent as in the male; prothorax nearly similar but wholly black; elytra broadly oval, evidently longer than wide, deep black and wholly immaculate; inflexed margin finely ridged; hind wings apparently vestigial; under surface and legs piceous to black. Length (7°) 1.6-2.1 mm.; width 1.18-1.35 mm. North Carolina (Southern Pines),—Manee. Eight specimens. The pale side-margins of the pronotum in the type of nubilatus, by comparison with asphaltina, where there is no trace of pallid coloration, shows that nubilatus, as described above, is represented by the male. On comparing this with the male of asphaltina, there are several radical differences, nubilatus being broader, with more arcuate sides, rather smaller head, with less prominent eves and nubilously pallid elytral flanks, of which there is no trace in asphaltina. These two species in fact represent a distinct section of the genus, characterized probably among other ways by less arboreal habits. The following is one of the most isolated species of the genus, but for the present may be placed in the preceding section: Hyperaspis sexualis n. sp.—Very small, oblong-suboval, convex, shining, finely, loosely punctate, deep black. Male with the head two-thirds as wide as the prothorax, pale flavate, abruptly deep black in nearly basal third, the anterior line of the black area minutely sinuate at the middle; prothorax more than twice as wide as long, almost parallel, the sides feebly arcuate; surface wholly black; elytra parallel, with moderately arcuate sides and rapidly broadly rounded apex, barely at all longer than wide and a third wider than the prothorax, wholly black. Female larger and more oval, wholly black above, the head four-sevenths as wide as the prothorax, the latter scarcely more than twice as wide as long, the sides very little more converging than in the male, feebly arcuate; elytra longer, oblong, with arcuate sides and broadly rounded apex, slightly longer than wide; under surface black, the legs blackish; tips of the femora, and the tibie at tip or throughout, pale. Length 1.3-1.65 mm.; width 0.8-0.95 mm. Utah (St. George),—Wickham. Four specimens. The head in the male is slightly wider than an elytron; in the female it is correspondingly narrower than an elytron. This is the smallest species of the genus known thus far. The two following species are somewhat as in Hyperaspidius in the type of coloration: Hyperaspis durangoensis n. sp.—Broadly and obtusely oval, shining, deep black, the elytra rather strongly but loosely punctate, the anterior parts very 168 MEMOIRS ON THE COLEOPTERA finely and more closely; head about half as wide as the prothorax, flavate (@), wholly black (2); prothorax two and a third times as wide as long, the oblique sides very feebly arcuate in both sexes, black, with a rather narrow entire flavate side-margin; elytra similar in the sexes, subquadrate, broadly rounded at apex, the parallel sides moderately arcuate, the sides rather narrowly and shallowly, bisinuately flavate, this line flexed inwardly along the base, ending in a rounded dilatation near the scutellum, also flexed inwardly at apex very close to the margin, gradually broadening and obliquely truncate near the suture; from the anterior part of this oblique apex extends a flavate straight line, parallel to the suture, from inner fourth to the median line and ending between basal third and fourth; under surface black, the abdominal tip pallescent, the epipleura pale yellow, the legs brown. Length 2.3-2.5 mm.; width 1.6-1.7 mm. Mexico (Durango City), —Wickham. Two specimens. This is a remarkably well-characterized species, apparently not allied to any other now known from Mexico, except the following: Hyperaspis disjunctus n. sp.—More narrowly oval than the preceding, shining, rather distinctly though finely punctured; head black in the type, a little more than half as wide as the prothorax, the latter almost as in durangoensis and with similar narrow flavate line at the sides; elytra distinctly elongate, oval, moderately obtuse, each with a triangular pale spot near the baseand scutellum and another triangular and widely isolated spot at each humeral angle, also with a larger, transversely triangular spot slightly within the apical margin, its inner limit oblique, this spot continued anteriorly by two narrow lines to barely before the middle, the outer line marginal, the inner near inner third, gradually receding still further from the suture than at its point of origin; under surface and legs black or nearly so, the epipleura pale. Length 2.0mm.; width 1.3mm. Mexico (Durango City),—Wickham. While this species is rather closely allied to the preceding and occurs at the same place, I have no doubt, from what I have learned of the laws of variation in this genus, that it is distinct. It is represented by a single female specimen. Hyperaspidius Cr. This genus is composed of a moderate number of species, in general smaller in size than those of Hyperaspis and distinguished by narrower epipleura, not impressed for the tips of the femora, as they are in /Typeraspis. The following three species seem to be worthy of description at the present time: Hyperaspidius brevilinea n. sp.—Very short, oblong, moderately convex, shining, finely and inconspicuously punctulate; head fully two-thirds as wide as the prothorax, pale piceous, gradually a little darker basally; prothorax distinctly more than twice as wide as long, the sides only very moderately oblique and feebly arcuate; surface piceous-brown, the sides not broadly yellow, this pale area gradually narrowing and not quite attaining the base; elytra parallel, as wide as long, the sides very moderately arcuate, the apex rapidly transverse and very obtuse; surface black, each with a narrow yellow margin from the scutellum to apical fifth or sixth, there rapidly flexed inward and distinctly dilated, extending not quite to the suture and at a slight distance from the apical edge; at about ADDITIONS TO NORTH AMERICAN COLEOPTERA 169 inner third there is a narrow yellow dash from basal third to nearly three-fourths; under surface and legs rather dark testaceous. Length 1.7 mm.; width 1.3 mm. Mexico (Saltillo, Coahuila),—Wickham. The single specimen at hand represents a species not closely allied to any other in my collection. The sex of the type is not definitely known, but it is probably female. Hyperaspidius mimus n. sp.—Very small, narrow and parallel, polished, minutely, loosely punctulate and only moderately vaulted; head black, with rather prominent eyes, fully three-fourths as wide as the prothorax, ,which is distinctly more than twice as wide as long, with feebly oblique and very slightly arcuate sides; surface black, with narrow antero-posteriorly narrowed yellow margins; elytra nearly a third longer than wide, only slightly wider than the prothorax, with parallel and feebly arcuate sides and broadly rounded apex; surface with a rather broad and even, whitish line from near the suture at apex, along the apex—very narrowly separated therefrom—along the sides, base and suture continuously to apical fifth, without pale marking other than this; under surface piceous, with pale and rather slender legs. Length (2) 1.4 mm.; width 0.75 mm. Colorado (Boulder Co.),—Mrs. T. L. Casey. I have deferred the description of this species for some time, awaiting material additional to the single type specimen, but I now consider it distinct, though allied rather closely to vittigera Lec. and comparata Csy., from Texas and the middle California coast respectively; it is very much narrower than either of these, although almost similarly marked; the body is narrower and the eyes more prominent. Hyperaspidius pallidus n. sp.—Oblong, parallel, convex, polished and pale yellowish-testaceous throughout above and beneath; punctures of the head very fine but rather close and deep, of the pronotum very minute and rather sparse, of the elytra small but deeper, larger and much more conspicuous, although sparse; head about three-fourths as wide as the prothorax, the eyes deep black and unusually prominent; prothorax more than twice as wide as long, nearly parallel, the sides distinctly arcuate; elytra almost a third longer than wide, only a little wider than the prothorax, parallel, with feebly arcuate sides, a little more rounded basally, broadly rounded at apex; under surface finely, sparsely punctate. Length 1.75 mm.; width 0.85 mm. North Carolina (Southern Pines),—Manee. A single specimen of undetermined sex. This distinct species may be placed next to transfuga, from Mt. Tom, Mass., but it is a little larger, with pale and not infuscate head, having slightly larger and more prominent eyes, the prothorax much more transverse, being only twice as wide as long in transfuga, and with longer and more strongly punctured elytra. Delphastus Csy. This is a genus of small and broadly oval or rounded glabrous species, of which pusillus Lec., is common and widely diffused in 170 MEMOIRS ON THE COLEOPTERA eastern North America. The following is allied to pusillus but is still broader: Delphastus subtropicus n. sp.—Very broadly rounded and almost hemispherical, deep black and polished, the anterior parts with very faint steel-bluish lustre; punctures minute and sparse; head scarcely half as wide as the prothorax, the latter between two and three times as wide as long, with oblique and feebly arcuate sides; elytra barely as long as wide, subcircularly rounded, at the middle but little wider than at base and slightly wider than the prothorax; under surface piceous, the legs testaceous. Length 1.25 mm.; width 0.85 mm. Florida (Key West),—Schwarz. Almost similar in size to pusillus but more circularly rounded and with feeble steel-blue lustre anteriorly, this being unobservable in pusillus: in the latter, also, the under surface and legs are black or very nearly so, and the elytral punctures more minute, sparser and barely evident; the outline of the body is feebly suboblong and a little narrower than in subtropicus. Delphastus violaceus n. sp.—Subevenly rounded and very convex, somewhat smaller and a little less broad than in subtropicus, bright steel-blue, the elytra violaceous, highly polished, the punctures minute, sparse and very inconspicuous; head rather more than half as wide as the prothorax, the latter but little more than twice as wide as long, the sides moderately oblique and rather feebly arcuate; elytra very little longer than wide, the sides rounding from near the base to the sutural angles, the humeri slightly and obtusely subtumid; under surface black, the legs slender, flavo-testaceous, the hind femora somewhat infuscate. Length . 1.18 mm.; width 0.7 mm. Cuba (Cayamas),—Schwarz. This very interesting species is evidently allied to subtropicus and pusillus, but is slightly narrower and with narrowly basally exposed humeri, not evident in the others; it also differs conspic- uously in its metallic coloration. The western sonoricus Csy., the fourth known species of the genus, is a little smaller than puszllus and notably narrower. Delphastopsis n. gen. Body rounded, strongly convex and glabrous, feebly sculptured; general characters nearly as in Delphastus, but the eyes are much larger, separated by but little more than their own widths and with flatter and relatively smaller facets. Scutellum triangular, similarly well developed. Legs and tarsi nearly similar, the an- terior coxe near the apical margin of the prosternum. Epipleura similarly narrow, deeply but not quite so sharply foveate and not so flat, the external margin descending somewhat. The type is the following: Delphastopsis amazonica n. sp.—Very broadly rounded, almost hemispherical, polished and deep black; head rather small, much less than half as wide as the ApDITIONS TO NORTH AMERICAN COLEOPTERA 171 prothorax, the latter about three times as wide as long, the sides strongly oblique and feebly arcuate; - punctures fine but rather deep, well separated; elytra scarcely as wide as long, very broadly rounded, the humeri slightly tumid, fully a fourth wider than the prothorax, the punctures so minute, feeble and sparse as to be observed with difficulty; under surface and legs rufo-testaceous. Length 1.45 mm.; width 1.25 mm. _ Brazil (Obidos),—H. Rolle. Larger and still broader than Delphastus pusillus and the few other species known so far. The following genus also belongs near the preceding and Delphastus. Delphastobia n. gen. Body broadly oval, strongly convex and glabrous. Eyes narrow, more strongly faceted, separated by between two and three times their widths. Scutellum invisible, except under high magnification, triangular. Anterior coxe large, extending to the anterior margin of the prosternum, well separated; epipleura narrow, with a large deep excavation at base, the outer margin descending somewhat. Legs short and rather thick, the tarsi short, broad and parallel. Lines of the first ventral extending along the posterior edge of the first segment. The type is as follows: Delphastobia mexicana n. sp.—Oval, feebly attenuated from the large and slightly tumid humeri to the well-rounded apex, deep black and shining, the anterior parts with very feeble micro-reticulation and with very fine, shallow and sparse punctures; head two-fifths as wide as the prothorax, the latter slightly more than twice as wide as long, with very oblique and feebly arcuate sides; elytra slightly longer than wide, at the tumid humeri distinctly wider than the prothorax, the punctures very minute, remote and in part subserial; under surface and legs deep black. Length 1.7-1.85 mm.; width 1.15-1.25 mm. Mexico (Rio Balsas, Guerrero),—Wickham. The head has a feeble greenish-metallic lustre. The exceedingly minute scutellum is a remarkable character. Scymnus Kug. The species of this genus are all very small, generally oval and more or less pubescent; they are exceedingly numerous in nearly all parts of the world. The following are only the notably distinct species now unnamed in my collection, and there are besides a number of nondescripts, which are so closely allied to others that more time should be taken in their description than I can spare at present: Scymnus frosti n. sp.—Oval, rather elongate and convex, moderately shining, finely, rather sparsely punctate and with short and not dense ashy hairs; head black, fully half as wide as the prothorax, the latter wholly black, with somewhat 172 MEMOIRS ON THE COLEOPTERA feebly converging and slightly arcuate sides; elytra between a fourth and third longer than wide, oval, somewhat obtusely but evenly rounded at apex, the sides almost continuous with those of the prothorax, black, each with two rufo- flavate discal spots, one parallel in form from inner third to outer fourth, oblique from basal fifth to a little before the middle, the other transversely oval and larger, from inner to outer fifth or sixth and at two-thirds to four-fifths of the length; under surface in great part black, the legs piceous. Length 1.85-2.0 mm.; width 1.18-1.22 mm. Massachusetts (Framingham and Sherborn),—C. A. Frost. Allied to ornatus Lec., from the north shore of Lake Superior, but notably shining, ornatus being described as without lustre; there are probably other differences relating to the relative sizes and form of the maculations. The two following species may be placed near flavifrons, bioculatus and bivulnerus: Scymnus ludovicianus n. sp.—Regularly oval, convex, shining and black throughout above, except a large rounded testaceous spot on each elytron, from the middle to apical fifth or sixth and from inner to outer sixth or seventh; punc- tures fine, well separated, the pubescence very short, ashy, loose and inconspic- uous; head less than half as wide as the prothorax, the latter between two and three times as wide as long, with oblique and very moderate sides; elytra evenly oval, a fourth longer than wide, at the middle about a fourth wider than the prothorax; supra-humeral umbo small and feeble; under surface black, the abdomen dark rufous, the legs piceo-rufous. Length 1.65 mm.; width 1.1 mm. Louisiana (Alexandria). The type is a female; it differs from the female of flavifrons in the much larger and somewhat more apical elytral spots. Scymnus aztecanus—Smaller, shorter and relatively broader, black, rather shining and finely, loosely punctate, the ashy vestiture very short, not very close but distinct; head (<@) flavate, slightly more than half as wide as the prothorax, which is but little over twice as wide as long, the moderately oblique sides broadly arcuate; surface (o’) black, with a narrow, basally obsolete testaceous border; elytra not very evidently longer than wide, broadly oval, a fifth wider than the prothorax, with arcuate sides and very obtusely ogival apex, black, each with a moderately transverse flavate discal spot from two-thirds to three-fourths and from inner to outer third or fourth; under surface black, the legs short, flavate. Length 1.2-1.25 mm.; width 0.8-0.85 mm. Mexico (Rio Balsas, Guerrero). This very small species belongs to the bioculatus section, but is still smaller, and the posterior discal spots of the elytra are not circular but transversely subquadrate in form; the head and pronotum in the female are entirely black. Scymnus emertoni n. sp.—Much smaller and more abbreviated than the preceding, moderately convex, suboblong-oval, shining; head pale flavate in the presumably male type, a little less than half as wide as the prothorax, the latter much more than twice as wide as long, black, with rather wide subeven flavate lateral margins, finely but rather deeply, not densely punctate, the sides feebly oblique, more rounding apically; elytra barely visibly longer than wide, parallel, AppITIONS TO NORTH AMERICAN COLEOPTERA 7G with feebly arcuate sides, more rounded at base, the apex broadly and obtusely rounded, about a fourth wider than the prothorax, with small but deep and strong, moderately separated punctures and very short inconspicuous ashy pubescence, each with two conspicuous yellow discal bars, each constricted slightly in its middle, the anterior oblique from inner to outer sixth and from near the humeral callus to four-sevenths, the posterior transverse, more medially con- stricted and extending from inner sixth virtually to the side margin and from about two-thirds to three-fourths; under surface black, the legs, entire abdomen and epipleura pale flavate.
