nearly straight and feebly divergent thence to the base, and more strongly 

 convergent to the acute and very slightly prominent apical angles ; apex 

 broadly, feebly emarginate ; base transverse, broadly and very distinctly 

 sinuate laterally; disk transversely, very strongly convex, rather coarsely, 

 very deeply and extremely densely pvinctate. Scutellum moderate, punctate. 

 Elytra about three times as long as, and very slightly wider than, the protho- 

 rax ; sides parallel and slightly arcuate ; apex rather narrowly rounded ; disk 

 with rather fine, very feebly impressed striae which are finely, feebly and 

 approximately punctate ; intervals nearly flat, four or five times as wide as 

 the striae, finely granulose, rugulose and very minutely, rather densely punc- 

 tate. Abdomen shining, finely and not very densely punctate, uniformly clothed 

 throughout with rather short, fine, recumbent, pale but sparse and inconspicu- 

 ous pubescence. Legs and tarsi rather short and robust. 



Male. — Anterior tarsi feebly dilated and squamulose beneath, the interme- 

 diate not dilated but with a few squamules beneath ; abdomen toward base 

 narrowly and scarcely perceptibly flattened. 



Length 4.2-4.9 mm. ; width 1.8-2.1 mm. 



Kansas ; Colorado. 



One of the most aberrant species of the genus, easily recognizable 

 by its strongly convex elongate-oval form, feeble elytral stride and 

 coarse squamiform pale and conspicuous vestiture. 



36 B. llOSpes n. sp. — Oval, very convex, somewhat dull, grayish-black ; 

 pubescence rather long and abundant, rather coarse, pale cinereous and con- 

 spicuous, recumbent. Head feebly convex, very densely punctate ; upper lobe 

 of eyes moderate ; antennae rather robust, outer joints gradually and rather 

 strongly dilated, third short, scarcely two-thirds longer than the second, much 

 shorter than the next two together, seventh distinctly wider than long. Pro- 

 thorax about three-fourths wider than long, the apex a little narrower than 

 the base ; sides almost evenly and very feebly arcuate ; base transverse, the 

 sinuations broad and distinct ; basal angles right, rather prominent, not at all 

 rounded ; apex very feebly emarginate in circular arc ; disk somewhat coarsely 

 and very densely punctate, the punctures usually a little sjjarser toward the 

 middle, and more or less longitudinally coalescent toward the sides but never 

 forming long rugae. Scutellum small, not very densely punctate. Elytra 

 about two and one-half times as long as the prothorax and, behind the middle, 

 just visibly wider, somewhat acutely rounded behind ; disk with fine strias 

 which are excessively feebly impressed and extremely finely, feebly punctured, 

 the punctures generally separated by about twice their own diameters ; inter- 

 vals nearly flat, sparsely and very minutely punctate. Abdomen strongly 

 shining, very finely, rather sparsely punctate, the pubescence moderate in 

 length, sparse, cinereous but not very consi^icuous. Legs short. 



Male. — Anterior tarsi rather strongly dilated, the second and third joints 

 equal in length, the latter slightly the wider; intermediate more feebly but 

 distinctly dilated ; bo'/"^ pairs densely and rather coarsely s^^ongy-pubescent
