I am doubtful of the sex of my unique example of this species, 



which belongs to a group in which there is usually very little 



external difference between the sexes, — but the front tibiae being 



decidedly broad I suspect it is a female. It is near O. henleyensis^ 



Blackb.; but that species has elytra non coriaceous and very 



much more rugulose, and considerably narrower eyes. 



Victoria ; I am uncertain of the exact habitat.

 Allied to O. muticus, Mad, and inermis, Macl. This species 

 differs from the insect which I believe to be the former infer alia 

 by its sparsely and strongly punctulate metasternum ; from that 

 which I take to be inermis by, inter alia^ its still more polished 

 surface and its elytral interstices very conspicuously punctulate. 

 The sides of the prothorax are much more strongly rounded than 

 in any specimen that I have seen of either of the species just
