surface rather sparsely and shallowly punctate, each puncture 

 carrying a scale. Femora very stout, scarcely twice as long as 

 wide, compressed, feebly punctate; tibiae rather strongly punc- 

 tate, beneath seriate-punctate, the series separated by narrow 

 ridges. Length 7^, rostrum 1^; width 3^ mm.

 Wales. 



In the Transactions {supra) Mr. Waterhouse says that he was 

 not sure whether his specimens were from Australia or New 

 Zealand; but, in the Proceedings, the habitat is given as Rich- 

 mond River. Mr. Pascoe says that the species is " without 

 doubt" from Queensland. There are specimens from the 

 Clarence River in the Macleay Museum.

Rostrum comparatively short and stout, slightly curved at 

 base. AntemKB stout; scape short and stout, inserted nearer 

 base than apex of rostrum, much shorter than funicle; club 

 short, ovate, free. Prothorax slightly transverse. Elytra very 

 slightly wider than prothorax, sides subparallel to near apex, 

 apex rounded. Intercoxal process of abdomen moderately wide. 

 Tibice compressed, curved, in addition to the (rather strong) 

 terminal hook with a small subapical tooth, and above with a 

 small acute one, which is sometimes obscured by scales. 



M. Lacordaire places both Chcetectetorus and Sympiezoscelus in 

 his fourtli " groupe," the former in the CryiJtorhynchides vrais, 

 the latter in the Sympiezoscelides, the two being distinguished by 

 the shape of the femora. Both, however, agree in having the 

 metathoracic episterna very large, in which respect they differ 

 from the Tylodides. Without seeing Mitrastethus (unknown to 

 Lacordaire), I would probably have considered the two divisions 

 necessary, but this genus leaves no doubt in my mind but that 

 it, together with Sympiezoscelus and Bepharus, belong to the 

 Chwtectetoi'us-grou^j the three genera being so closely allied that 

 it would be ridiculous to separate them. Of Mitraststhus I know
