wide, subtriangular with feebly arcuate sides, the subapical swellings distinct ; 

 humeri rounded, very moderately exposed and scarcely prominent; striae mod- 

 erately fine, punctured. Legs rather short, the femoral enlargement moder- 

 ately strong, the teeth rather well developed but with the distal slope oblique. 

 Length 6.3-6.5 mm.; width 3.2 mm. 



New Mexico (Las Yegas). 



The type described above is a female, in order to better com- 

 pare the species with those closely related. The male is a little 

 shorter, with the prothorax relatively smaller, and the humeri 

 more exposed and prominent ; the beak is scarcely shorter than 

 in the female, ^ as long as the body, more strongly and evenly 

 arcuate, more punctured and carinate above toward base and 

 with the antennae inserted at apical |- ; the abdomen is broadly 

 impressed at base toward the middle, and the fifth segment is 

 sinuato-truncate at tip. 



This species is evidently allied to obtusus, but differs in its 

 smaller size, less obese form, relativelj^ larger prothorax of the 

 female, narrower and less broadly oval dense scutellar cluster of 

 squamules, less variegated vestiture and in numerous other 

 characters. 



B. moiiticola. — Elongate-suboval, strongly convex, black, the legs feebly 

 rufescent ; beak and antennse ruf o-piceous ; vestiture dense, consisting of rather 

 broad whitish scales, variegated with browner patches on the elytra, a 

 transverse band of whitish near apical third more conspicuous, the scales nar- 

 rower and brownish on the pronotum, where they are arranged transversely as 

 usual, broader and paler beneath. Head }-{ as wide as the prothorax, the eyes 

 separated by % of their own width, without distinct intermediate puncture, 

 the beak scarcely more than }4 as long as the elytra, moderately stout, arcuate 

 distally, the antennae inserted slightly behind the middle, the scape nearly as 

 long as the first four joints of the funicle, the latter decreasing in length ; club 

 moderate in size, rather stout. Prothorax well developed, scarcely ^5 wider 

 than long, the sides subparallel and broadly arcuate to near apical third, then 

 more rapidly rounded and convergent, becoming sinuate near the apex, the 

 latter subtubulate, truncate, feebly sinuate at the middle ; surface densely 

 punctate. Elytra not ^4 longer than wide, rather more than ^.^ wider than the 

 prothorax, subogival in form, the subapical prominences moderate; humeri 

 moderately exposed and rounded. Legs and femoral dilatation moderate. 

 Length 6.5 mm. ; width 3.2 mm. 



Colorado (Colorado Springs). Mr. Wickham. 



The onl}'^ specimen known to me is a female, the fifth ventral 

 being triangular in form and with a pronounced medial indenta- 

 tion toward tip. This species is allied somewhat to oUusus and
