 Somewhat close to //. jnceonfger, Macl., but differing in 

 colour, in its smaller head, in the sides of its prothorax con- 

 siderably more arched, and in the less close and more seriate 

 puncturation of its elytra. Also near nierus, Blackb., but 

 differing from that species by, inter alia, the better defined 

 and considerably more expanded hind angles of its pronotum. 



Central Australia ; Oodnadatta. 

 H. declaratus, sp. nov. Minus elongatus ; minus nitidus ; 

 obscure brunneus ; supra pilis brevibus adpressis sparsim 

 vestitus ; subtus sparsim pilosus ; clypeo crebre ruguloso, 

 antice late leviter sinuato ; labro summo clypei planum 

 haud attingenti ; fronte sat grosse ruguloso-punctulata ; 

 fronte clypeoque ut plana disparia visis (sutura clypeali 

 cariniformi) ; antennis 9-articulatis ; prothorace quam 

 longiori ut 7 ad 4 latiori, antice sat angustato, supra

 iori, unguiculis bifidis. Long., 3 1.; lat., If 1. 

 A very isolated species, which seems out of place among 

 the species with which its structural characters associate it. 

 Its hind femora considerably dilated, with their front out-
