It is difficult to believe that this common species is undes- 

 cribed and yet there seems to be no doubt that such is the case. 

 It is nearest, I think, to macleayanus, Westw., to which it bears 

 considerable resemblance ; but it differs from that species inter alia 

 in the wider form aad less coarse puncturation of its prothorax 

 and in the sculpture of its elytra ; these in macleaymius present 

 alternately more and less convex lines, the former more nitid and 

 rugulose than the latter ; in the present species the lines of 

 sculpture are equally inter se convex nitid and rugulose and are 

 narrower and separated from each other by more defined and 

 numerous striae. The tarsi of macleayanus, moreover are shorter 

 and more robust.

A very distinct species with the prothorax very like that of 



hopeanus, Westw., but more narrowed in front, and having the 



basal angles dentiform ; and differing from hopeanus inter alia by 



the presence of quill-like appendages at the base of the claws ; 



also like emarginatus, Waterh., but differing from it infer alia by 



there being no angle before the posterior emargination of the sides 



of the prothorax.
