NORTH americ;an coleoptera. 21 



not impressed, the form smaller and more slender, it has been noticed 

 that the lateral pieces of the S genitalia are simjile and acute at tip, 

 not barbed as usual. 



The type of fulvlpes Lee. is a 9 , feebly purple bronzed ; legs en- 

 tirely yellow. One specimen in the LeConte collection has the tho- 

 rax densely punctured and opaque, but otherwise seems to be like 

 the type. Some very robust females from Oregon might be con- 

 founded with latiuscnlus, but the thorax is finely punctulate, and the 

 males are of the usual form. 



23. C COiive.'Klilus Lee— Robust, black, shining, clothed with subcinereous 

 pubescence and very fine suherect bristles, tarsi rufous. Antenna^ black, serrate, 

 as long as the head and thorax in the % , with joints broader at middle, shorter 

 in the J. Head and thorax punctulate, with sparser coarser punctures inter- 

 mixed, thorax very convex, tumid above, sides rounded and narrowed in front, 

 less narrowed and feebly sinuate or oblique behind, feebly impressed at middle 

 in front of the base and as usual on each side of the basal lobe, which is triden- 

 tate, the middle tooth a little less prominent, basal plicfe moderate. Elytra a 

 little wider than the thorax, punctate striate, intervals feebly convex and punc- 

 tulate, sides suliparallel, narrowed and rounded at tip Body beneath punctulate. 

 the larger punctures not very evident on the prosternum or flanks, distinct be- 

 hind, submarginal lines of prothorax feeble, rarely reaching the middle and also 

 rarely, quite obsolete, hind coxal plates transverse behind, angles rather strongly 

 rounded. Legs black, tarsi rufous, first joint of middle and hind tarsi about 

 equal to the last. Length .30-.40 inch ; 7.2-10 mm. 



Canada (Horn), White Mountains, N. H., Mass., Me., Ohio. 



Known from the previous species by the greater convexity of the 

 tborax, best compared in a lateral view ; the coarser punctures are 

 rather less evident above and the bristles, distinct in well preserved 

 specimens of the last, are here very fine or scarcely noticeable. The 

 9 is sometimes very stout, with the altei-nate intervals of the elyti'a, 

 especially the sixth and eighth, more elevated. 



24. C criiiitus n. sp. — Slender, feebly bronzed or black, shining, clothed 

 with more or less distinct white and brownish mixed pubescence and brown 

 bristles. Antennje black, or with the basal two joints rufescent, slender, not 

 very strongly .serrate. Head, more strongly, and thorax moderately closely 

 punctulate, the latter moderately cunvex, not or scarcely longer than wide, with 

 the sides more or less strongly rounded and narrowed in front and sinuate be- 

 hind, the angles divergent, impressed in front of the basal lobe and transversely 

 each side, lobe feebly tridentate. plicae short or moderate. Elytra wider than 

 the thorax, subparallel, moderately convex, punctate striate, the strise feebly im- 

 pressed on the disc, more strongly at ba.se and sides, intervals feebly convex or 

 flat, punctulate. Body beneath distinctly, rather closely punctulate, less closely 

 on the prosternum, on which aiul on the propleuriE the coarser punctures are 

 not evident, iiunctuation double behind, submarginal lines of ])rothorax im-
