c? . Rostrum with the apical portion sparsely punctate to near the tip, at most feebly subangulate towards 



the apex beneath (as seen in profile) ; ventral excavation broad, shallow, long.

front.

Found in abundance at Capetillo and also in some of the Mexican localities. A 



very variable insect and extremely difficult 



It may 



broad form ; the more or less rounded sides of the prothorax ; the 



somewhat closely placed, rather larg 



on the upper surface (which 



are always more crowded along the elytral suture); the bidentate peduncle of 



submentum of the femal 



of the male. The elyt 











often have a darker triangular patch near the suture before the middle and they are 

 sometimes wholly or in part ferruginous, the prothorax, too, in light-coloured examples 

 is broadly rufo-bivittate on the disc. The under surface (except down the middle) in 

 many of the fresh specimens before me is covered with a uniform brownish-white 

 incrustation. B. alboscutellatus, Chevr., is based upon a clean example (fig. 3 

 with a pruinose white scutellum, and the var. j3 (=puncticollis i Chevr.) (the types of all 

 of which I have seen) upon worn individuals of the same species.
