Near C. cylindricus in many respects, but very differently 

 coloured, with the eyes less remote, the prothorax and elytral 

 interstices much more closely [though not much less faintly 

 (prothorax) or finely (interstices)] punctured, the punctures in 

 the discal series scarcely so large (at least seven in the length of 

 a line), and distinctly smaller in the series near the suture and 

 lateral margins. The shape also is distinctly less cylindric ; this 

 is especially notable if the insects be looked at from the side, when 

 the upper outline of cylindricus appears as a nearly straight line 

 from the base of the elytra to considerably beyond the middle, the 

 corresponding outline in mimus being a curve ; in niimus, more- 

 over, the prothorax viewed from above is at its widest more 

 exactly at the base, while in cylindricus it seems almost to dilate 

 (or at any rate not to narrow) immediately in front of the base. 

 C. mimus also resembles C. tyrrhenus, Pasc, but that species is 

 more cylindric (almost as much so as cylindricus), with the 

 prothorax wider in front, the elytra striate, the eyes a little more 

 remote, &c.

 This species is perplexingly like C. longipennis, Hope. I have 

 before me two examples (both from the neighbourhood of King 

 George's Sound) which are probably male and female, since they 

 differ from each other by characters similar to those which dis- 

 tinguish the sexes of longipennis, and which also differ from each 

 other in the underside of one being quite black while the corre- 

 sponding surface of the other is faintly tinged with coppery colour. 

 They both differ from longipennis in their tarsi being shorter and
