This species forms with //. infuscatus, Macl., rotundi- 

 frons, Blackb., and ftctus, Blackb., an aggregate of closely- 

 allied species. From both the former two it differs, inter 

 alia, very conspicuously by the nearly straight sides of its pro- 

 thorax, which is at its widest across the base. From H. fictus, 

 which resembles it in the shape of the prothorax, it differs 

 by the character mentioned in the tabulation and also by the 

 much less coarse puncturation of its dorsal surface. The tri- 

 lobed outline of the head, though distinct, is very feebly 

 developed and not divided, the middle lobe a little more than 

 half a lateral lobe in size. My specimens of this insect are 

 from New South Wales, but I am not sure of their exact 

 habitat : I believe they were sent to me from Mulwala by 

 Mr. Sloane.

Closely associated with II: lucidus in respect of its more im- 

 portant structural characters, but differing from that species 

 in the form of its front tibiae and in the much coarser punc- 

 turation of its dorsal surface. The three specimens before me 

 are all of smaller size and lighter colour than any specimen
