ments almost completely concealed by the extremely dense vestiture, which is 

 pale yellowish in color and rather long throughout. Head and beak extremely 

 densely clothed throughout, when denuded minutely and densely punctate, 

 the beak in the male a little shorter, in the female distinctly longer, than the 

 prothorax, in the latter sex often denuded in apical half, cylindrical, feebly 

 arcuate, not in the least carinate, the antennae inserted near apical third 

 (male), or just before the middle (female). Prothorax but slightly wider than 

 long, the apex feebly arcuate, scarcely more than one-half as wide as the base, 

 the latter almost transverse, very feebly lobed in the middle ; sides strongly 

 convergent from base to apex and rather strongly, evenly arcuate, sometimes 

 feebly constricted near the apex in the female ; disk with a rather large and 

 deep basal impression, minutely, extremely densely punctulate and with 

 rather coarse, widely and very unevenly dispersed punctures, the entire 

 sculpture including the punctures almost completely concealed by the vesti- 

 ture. Elytra distinctly more than twice as long as wide, about three times 

 as long as the prothorax and nearly one-fourth wider than the latter, the 

 humeri oblique ; sides parallel and straight ; apex broadly rounded, minutely 

 notched ; disk with unimpressed rows of not very coarse, rather distant punc- 

 tures. Abdomen very densely, evenly clothed with long hair, sparsely speckled 

 toward base with subdenuded punctures, each bearing a longer and coarser 

 seta. Legs moderately long and stout, very densely clothed throughout. 

 Length 9.0-11.8 mm. ; width 3.0-4.0 mm. 



Wyoming. 



This species is represented before me by a large series from sev- 

 eral localities in Wyoming, and is apparently plentiful but local; 

 it is commonly confused in cabinets with mixtus, a widely differ- 

 ent species with strongly carinate beak.

Colorado — LeConte. I have but little to add to the full and sat- 

 isfactory original description ; the prothorax, however, is stated to 

 be "scarcely longer than wide," whereas it is not quite as lone as 

 wide ; this overstatement of the relative length of the prothorax 

 seems to be a constant personal equation in most of Dr. LeConte's 

 descriptions, and due allowance must be made for it in identifications. 

 Mixtus is a remarkable species, represented as far as known to me 

 by the unique specimen in the LeConte cabinet; the pubescence 

 forms a broad and rather well-defined marginal vitta along the 

 prothorax and elytra. Length 10.0 mm. ; width 3.2 mm. 



19 L.. SObrimiS n. sp. — Rather slender and convex, somewhat shining, 

 black throughout, the antennae dark rufous, the club dusky ; vestiture sparse, 

 forming a dense lateral pronotal vitta and also somewhat broadly condensed 

 along the sides of the elytra, on the disk of the latter sparse, very short and
