I have seen four specimens of this iasect and do not observe 

 any sexual distinctions among them except that one of them (no 

 doubt a male) has front tibse more slender than the others. The 

 species is not near any other Australian OnthojjJiagus known to 

 me except geelongensis, Blackb., from which it differs inter alia 

 by its colour, by its clypeal suture obsolete except in the middle 

 where it becomes a short conical horn ; and by its pronotum very 

 evidently more coarsely and less closely punctulate, and edged 

 along its base by a fine raised line which is quite well defined in 

 the middle.
