the scales become slightly less slender and very deuse ; scales of the pronotum 

 linear and sparse, hecoming wider and denser toward the sides, broad and dense 

 on the under surface. Head fully 3^ as wide as the prothorax, the eyes sepa- 

 rated by slightly more than }'2 of their own width, the intermediate surface 

 not foveate ; beak slender, straight, becoming gradually feebly arcuate distally, 

 very nearly as long as the elytra and nearly ^ as long as the body, the an- 

 tennae inserted at basal third, the scape short, not as long as the first three 

 joints of the funicle, the latter decreasing rapidly in length. Proi/toraa; mod- 

 erately developed, scarcely % wider than long, the sides subparallel, evenly 

 and rather strongly arcuate, becoming more rapidly convergent and then sin- 

 uate anteriorly, the apex subtubulate and transversely rectilinear ; surface 

 rather coarsely, densely punctate. Elytra more elongate than usual in this sec- 

 tion of the genus, % longer than wide, % wider than the prothorax, evenly 

 elougate-ogival in form, acute behind, the subapical prominences almost obso- 

 lete ; suture slightly prominent toward tip ; humeri narrowly exposed and 

 rounded ; striae coarse, deep and punctate, 3^2 ^s wide as the intervals, the lat- 

 ter flat and rugose. Legs rather short, the femora only feebly inflated. Length 

 5.2 mm.; width 2.4 mm. 



New Mexico (Las "Vegas). 



This small species is allied structurally to uniformis hy the in- 

 sertion of the antennae, but is placed in the present subsection 

 because of the very short beak ; it is however quite isolated and 

 distinct. The fifth ventral of the female, which is the only sex 

 known to me, is broadly parabolic, and is scarcely visibly im- 

 pressed and not differentl.y clothed toward the middle. In the 

 female of unifor'niis the abdomen is clothed with narrower scales 

 toward tip and the fifth segment is deeply indented, the size, also, 

 being much larger; in addition to this the beak is as long as the 

 elytra, and the elytral intervals four or five times as wide as the 

 striae. 



B. brevirostris. — Stout, strongly convex and subrhomboidal, blackish 

 in color, the legs rufescent; beak and antennae rufous; vestiture consisting of 

 long slender scales, dense and concealing the integuments, pale luteous-brown 

 in color, with but feeble vestiges of variegation on the elytra. Head not quite 

 ^2, as wide as the prothorax, the eyes separated by fully % of their own width, 

 the interval flat, densely punctured but not medially foveate; beak very short, 

 scarcely more than }4, ^s long as the body, somewhat stout, straight, becoming 

 feebly arcuate toward tip, distinctly punctured toward base, the antennae in- 

 serted near basal %, the funicle rather slender, with the three basal joints de- 

 creasing rather rapidly in length, the club well developed. Prothorax relatively 

 rather large, % wider than long, the sides broadly and almost evenly arcuate 

 and feebly convergent from the base almost to the apex, where they become feebly 

 sinuate; apex feebly, subangularly emarginate; surface densely punctate, the 

 punctures largely coalescent sublongitudinally. Elytra slightly longer than
