Head nearly impunctate, palpi black ; antennae with the terminal joints distinctly widened, black, the basal joint flavous ; thorax scarcely more than twice as broad as long, the sides straight at the base, rather strongly obliquely narrowed anteriorly, the anterior angles pointed, the disc finely and rather closely punctured, the punctures of unequal size ; scutellum fulvous ; elytra regularly convex, finely punctured in irregular double rows near the suture, the sides irregularly punctate, fulvous, the extreme basal margin piceous, the interstices smooth ; below black, the anterior femora entirely, the others more or less fulvous below ; the mesosternal process short and broad. Hab. Colombia. (A single specimen.) The thorax in this species is less transverse in shape and more suddenly pointed anteriorly than in B. bahiaensis ; the elytra are differently sculptured and the mesosternal process is much shorter.

Oblong, below black, above and the legs dark fulvous ; thorax remotely and strongly punctured at the sides; elytra regularly punctate-striate, an interrupted ring-shaped band from the base to the middle and an entire similar ring near the apex, flavous ; antenna? and the last abdominal segments pale flavous. Length 9 millim. Head minutely punctured, pale fulvous, labrum testaceous; antenna? extending beyond the base of the thorax, pale fulvous, terminal joints subquadrately widened ; thorax nearly three times broader than long, the sides straight, rounded near the anterior angles only, the disc finely and remotely punctured, the sides more strongly so, but little flattened; scutellum pale ; elytra oblong and parallel, moderately convex, regularly and moderately strongly punctate-striate, fulvous, sometimes with a slight greenish tint, a ring-shaped band, interrupted at its inner and posterior margin, extending from the base to the middle and another nearly round and uninterrupted ring near the apex, obscure flavous; below black, with the exception of the fulvous legs and similarly coloured mesosternal process, the latter long and stout, slightly curved, last abdominal segment flavous. |
