DD. Hind angles of prothorax quite 



obtuse or rounded off jejunus, Blackb. 



CC. " Trilobed outline " of head well- 

 developed; middle lobe 

 scarcely half as wide as 

 lateral ones lateritius, Blaokb. 



Heteronyx normalis, sp.nov. 



Minus elongatus ; sat convexus ; pone medium leviter dila- 

 tatus ; minus nitidus ; piceus vel ferruginous; pilis pallidis brevi- 

 bus adpressis (nonnullis longioribus erectis intermixtis) vestitus ; 

 subsequaliter crebre subtilius punctulatus ; labro clypeum late sat 

 fortiter superanti ; antennis 8-articulatis ; unguiculis appendi- 

 culatis. [Long. 4-5 J, lat. 2-3 lines. 



Labrum decidedly overtopping level of clypeus which is widely 

 and roundly emarginate in front; ''trilobed outline" of head 

 having the lobes feebly convex, the middle one not very much 

 narrower than the others ; clypeal suture well defined, straight 

 and impressed ; head (especially the clypeus) a little more strongly 

 sculptured than the rest of the body. Prothorax nearly twice as 

 wide as long, and nearly twice as wide at base as at front 

 which is strongly concave, with sharp well-produced angles ; the 

 sides are gently arched converging slightly from base to middle, 

 thence more strongly ; the hind angles viewed from above appear 

 fairly well defined but not sharp nor directed hindward ; the base 

 is bisinuate and widely lobed in the middle. The elytra have 

 more or less appearance of striation (in one example before me it 

 is quite well marked) ; their transverse wrinkling is fine but distinct 

 (especially in front) ; the lateral fringes are not carried round the 

 apex, which is truncate with a narrow but distinct membranous 

 border. The puncturation of the whole upper surface is fine, 

 close, and even, with a tendency to become fainter and less close 

 from the clypeus hindward, till on the pygidium (which is sub- 

 granulate) it is feeble and hardly close ; it resembles that of H. 

 insignis, Blackb. The metasternum and hind coxae are of equal
