more or less quadrate, but very close to its front margin is sud- 

 denly contracted into an extremely short parallel-sided prolonga- 

 tion ; in both, the sides and front of this terminal piece meet in 

 sharp angles, and in .S'. interruptus there is also a well-delined 

 angle at the point where the head is contracted, while in 

 S. i^roximiis this part is rounded off.

B. Victoriensis, sp. nov. Nitidus ; prothorace fortiter punctulato, 



disco late depresso, medio vix elevato ; niger ; antennis pedi- 



busque piceo-rulis, elytris fulvo-castaneis ; his striatis, inter- 



stitiis subconvexis obscure punctulatis inter se ccqualibus.

Very like the common B. vittatus, Newm. Compared with it, 



the head does not differ noticeably — the prothorax is a little more 



elongate (being quite as long as wide) with the discal impression 



less marked — the elytra have not the sutural dark stripe, and 



their interstices are very different (the second being as wide as 



the first and third, and all of them being sliglitly convex). I do 



not think this species can be identical with B. miisinis, Pasc, 



which, however, it, perhaps, somewhat approaches ; its colour 



seems to be very different, and also I cannot find any elytral 



sculpture agreeing with that attributed to B. mnsirus^ whicli is 



said to have "three lateral alternate interstices costa^form." 



Victoria ; Alpine district.
