Easily distinguished from all the preceding species of 

 the subgroup by the labrum having its upper and lower 

 planes meeting roundly instead of in a defined line or stria. 

 From all the following species it is easily distinguished by 

 the fringe of setiferous granules at the apex of its elytra. 

 It seems to be widely distributed in all the interior regions 

 of Australia. I have seen specimens from the eastern parts 

 of Western Australia, the northern (but not tropical) parts 

 of South Australia, and from Western Queensland. A form 

 from tropical Queensland closely resembling it presents some 

 differences of sculpture — especially on the head — and is 

 likely to be specifically distinct; but as I have only a single 

 specimen it is better to regard it provisionally as a possibly 

 abnormal example of this insect. It should be noted that 

 the sculpture of the dorsal surface is a trifle closer in the 

 female of this species than in the male. 



Central Australia; very widely distributed.
