98 NOTES ON AUSTRALIAN COLEOPTERA, 



as wide as, and more prominent than, the lateral lobes ; its pro- 

 thorax is of very dissimilar form, being only feebly rounded on 

 the sides and having much better defined hind angles (especially 

 when viewed from above) ; the hind coxse are considerably longer 

 and have their external hind angles much more defined ; and the 

 produced apex of the basal piece of the hiud claws is much larger, 

 nearly equalling the apical piece in size. In the tabulation of 

 this group (see preceding species) this species falls beside R. 

 Darwini, Blackb., but diflPers from it inter alia by very much 

 less coarse protlioracic puncturation.
