that I have seen of lucidus. The trilobed outline of the head 

 is like that of lucidus, but the middle lobe is narrower— 

 scarcely more than half a lateral lobe.

 longitudine), lateribus (superne visis) prope medium for-

 This species is near H . borealis and sordidus. From the 

 former it is very easily distinguishable by the very much more 

 strongly rounded sides of its prothorax. It is much closer to 

 H. sordidus, from which it differs, however, by its evidently 

 wider form ; its prothorax less narrowed in front, with sides 

 even more strongly rounded, greatest width nearer the middle, 

 hind angles quite rounded off, and puncturation evidently a 

 little stronger and less close : its elytra! punctures a little less 

 close, less strongly impressed, and not asperate ; its hind 

 coxae very evidently shorter, etc. It bears much resemblance 

 to several species near the end of Group VIII. , from which its 

 claws (all of them bind) readily distinguish it. 



North Queensland (Mr. Perkins). 

 H sordidus, sp. nov. Modice elongatus, postice leviter dila- 

 tatus ; minus nitidus ; ferrugineus ; supra pilis brevibus 

 adpressis minus crebre vestitus : clypeo crebre ruguloso, 

 antice leviter emarginato ; labro clypei planum vix super- 

 anti : capite antice (a tergo oblique viso) tripliciter con- 

 vexo (parte mediana quam laterales sat angustiori) ; 

 fronte rugulose sat grosse punctulata ; hac clypeoque ut 

 plana sat disparia visis ; antennis 9-articulatis, brevibus ;
