392 MISCELLANEA ENTOMOLOGICA, 



This is the description given by Burrneister of this species, and 

 I cannot improve on it, as I have never been able to recognise it 

 with certainty. I have, however, seen at the Australian Museum 

 a specimen from Mt. Barker, near King George's Sound, which 

 resembles the description, and is, I think, very likely to be the 

 very species ; if so it undoubtedly belongs to my Sub-section A. 



SUB-SECTION B. 



Emargi nation of clypcus, more or less deep, the angles always 

 diverging.

 fovese rather large and the lateral margin reddish-pilose. Scutellum 

 triangular, smooth. Elytra coarsely and sub-transversely punctate.
