apice nigro ; capite prothoraceque fortiter rugulose punctulatis ; 

 hoc vix ineequali ; elytris crasse profunde seriatim punctulatis, 

 interstitiis vix conspiciiis. Long. 2 lines (vix), lat. ^ line. 



The clypeus is nearly black, shining and not very closely, 

 strongly or roughly punctured, the clypeal suture fairly defined 

 and a little angulous behind, the hinder part of the head obscurely 

 and very roughly punctured. The prothorax is punctured as the 

 hinder part of the head ; it is slightly wider than long, nearly 

 twice as wide in front as behinrl, its sides are gently rounded in 

 the front two-thirds, nearly straight behind, and owing to the 

 coarseness of the sculpture they appear to be strongly crenulate ; 

 the surface bears a vague elongate impression on either side near 

 the posterior angles with an obscure rounded imjDression close in 

 front of its anterior end. The elytra are at their widest behind 

 the middle ; their shoulders are quite rounded off; their sculpture 

 consists of ten rows of round deep foveoe, the fovese near the base, 

 apex and lateral margins smaller than the rest ; the rows are not 

 very regular and the intervals between them are not longitudinally 

 continuous, being in width and prominence similar to those 

 separating fovea from fovea in the rows ; the sutural line is very 

 elevated. 



I know no other species closely resembling this, but in order to 

 make a comparison I may say that, placed beside the European B.. 

 angustatus, Germ., independently of color, the prothorax is wider 

 in front and shorter, and the elytra are much wider behind with 

 very much less regular and coarser puncturation. 



I have a single specimen taken in the River Torrens near 

 Adelaide.
