side near the apex. The fades of the body is quite different from 

 that of an}' other species, owing to the short rhomboidal form, 

 prominent humeri and distinctly tubulate apex of the prothorax. 

 A single specimen, probablj^ from the extreme southern part of 

 the State. 



B. nanillus. — Eather short and stout, subrliomboidal, piceous-black, the 

 legs rufescent; beak and antennae pale rufous; integument densely clothed 

 ■with an almost uniform mixture of white and brown scales, the latter longer 

 and more slender; white scales of the strial punctures generally shorter and 

 broader. Head nearly }4 ^s wide as the prothorax, the eyes separated by but 

 little more than 14 their own width, the interval feebly sulcatulate; beak slen- 

 der, almost evenly arcuate, about as long as the elytra; antennse slender, in- 

 serted at about the middle, the first four joints of the funicle uniformly and 

 rather rapidly decreasing in length, the club elongate, fusiform and very 

 densely pubescent. Prothorax relatively small, fully 3^ wider than long, the. 

 sides parallel and nearly straight in basal %, then moderately convergent and 

 subrectilinear to the truncate apex; disk densely punctured, the slender scales 

 close-set and arranged transversely, meeting along a fine and rather prominent 

 median line. Elytra but slightly longer than wide, more than twice as long 

 as the prothorax and fully % wider, the humeri moderately exposed and sub- 

 prominent; sides feebly convergent to near apical third, then much more 

 rapidly and more arcuate to the tip ; striae moderately coarse and deep, rather 

 coarsely punctate, the intervals nearly flat and subrugose. Legs rather short, 

 the femora quite feebly inflated. Length 4.8 mm. ; width 2.3 mm. 



New Mexico (Las Yegas). 



The single representative is a male, having the abdomen dis- 

 tinctly impressed in the middle toward base, the fifth only 

 slightly flattened, with the vestiture becoming finer, more hair- 

 like and suberect toward the middle and tip, and with the apex 

 transversely truncate, the pj-gidium clothed densely with long 

 erect brown and white hairs, the former the longer. This species 

 seems to be quite isolated and not closely related to any other. 



B. occidentis. — Elongate-suboval, strongly convex, dark in color, with 

 dark rufous beak and antennae and very densely clothed throughout with 

 ochreous-yellow scales, only very slightly and unevenly variegated with some- 

 what darker brownish, the scales all long and very narrow, arranged trans- 

 versely and hair-like on the pronotum, where they generally become whitish 

 sublaterally toward base, paler, veiy broad, extremely dense and more closely 

 decumbent beneath. Head }4 f*s wide as the prothorax, the eyes separated by 

 but little more than }{ of their own width, the intervening surface scarcely 

 impressed; beak moderately slender, shorter than the elytra, nearly straight, 

 becoming arcuate distally, the antennse inserted slightly beyond the middle, 

 the funicle unusually stout and setose, with the first four joints decreas-
