fissures ; they are nearly flat anteriorly but strongly impressed 

 near the lateral edge posteriorly, the sutures distinct, the fissures 

 moderate in length and not entirely closed, the posterior edge below 

 the anterior appearing closed when viewed vertically, but widely 

 open near the coxae. The mentum is moderate, shining, coarsely 

 reticulate and nearly flat. 



This very distinct and beautiful species belongs, because of its 

 distinct sutures and half-closed coxal fissures, in the semiferrugi- 

 neus group of LeConte, but differs from every described species in 

 its prominent basal angles of the prothorax. 



B. foraininosus n. sp. — Rather robust and convex, black ; elytra 

 rufous, clouded with piceous-black toward base ; legs and antennae dark 

 testaceous, the latter blackish toward apex ; head finely reticulato-granulose, 

 moderately shining ; pronotum polished, not reticulate ; abdomen polished, 

 finely feebly reticulate. Head slightly narrower than the prothorax, slightly 

 convex ; eyes rather small ; surface distinctly and rather densely punctate ; 

 median fovea deep, distinct and slightly elongate, the surface immediately 

 about it polished and impunctate ; suture fine, feebly arcuate, distinct but not 

 impressed ; antennal prominences rather large but short and not very strongly 

 elevated ; antennse rather robust and compact, moderate in length, very evenly 

 and distinctly incrassate ; second joint but slightly longer than the third, sixth 

 distinctly wider than long, six to eight subequal in length, increasing in width, 

 nine and ten abruptly much longer but not wider, the latter rather longer tlian 

 wide, eleventh long, gradually pointed. Prothorax slightly narrower than the 

 base of the elytra, one-fourth wider than long ; sides in apical three-fifths 

 parallel and straight, then convergent and just visibly arcuate, and then 

 broadly rounded into the base, the basal angles being very obtuse, broadly 

 rounded and not distinct ; lateral angles very obtuse but rather narrowly 

 rounded and quite distinct, apical right and distinctly rounded ; apex broadly, 

 very feebly arcuate, the base very distinctly arcuate ; disk rather coarsely, 

 very deeply and densely punctate, the punctures almost contiguous laterally 

 but a little more dispersed toward the median groove, which is very coarse, 

 deep and conspicuous. Elytra scarcely as long as wide, one-fifth wider and 

 one-third longer than the prothorax, not very coarsely but very deeply and 

 rather densely punctate, the punctures sejmrated by slightly more than their 

 own widths ; pubescence moderate in length, not very dense. Abdomen par- 

 allel, almost as wide as the elytra, feebly, finely and not very densely punctate, 

 beneath polished and more densely punctate. Length 5.5 mm. 



California (Lake Co.). Mr. Fuchs. 



This species is allied to fumatus Lee, but differs greatly in its 

 smaller eyes, straight and not broadly rounded sides of the pro- 

 thorax, deeper and more distinct punctuation of the head, and, 

 especially, in the structure of the antennae which in fumatus are
