1220 REVISION OF THE GENUS HETERONYX, 



H. BoviLLi, sp.nov. 



Minus elongatus ; postice sat dilatatus ; ferrugineus ; pilis 

 brevibus adpressis sparsira vestitus ; crasse fortiter sat sparsim 

 (clypeo minus sparsim) punctulatus ; laVjro cljpeuni haud super- 

 anti ; antennis 8-articulatis ; coxis posticis metasterno pauUo 

 brevioribus; unguiculis bifidis. [Long. 3-4, lat. If -2 lines. 



The labrum is a little more prominent and upturned than in 

 typical species of this section. The clypeus forms an almost 

 perfectly even and continuous surface with the rest of the head, 

 the clypeal suture being scarcely visible ; its free margins are 

 moderately refiexed and its front is feebly concave in the middle. 

 The prothorax is about J again as wide as long, its base being 

 slightly more than ^ again as wide as its front, which is moderately 

 concave with moderately prominent and sharp angles ; the sidfis 

 are feebly arched (almost parallel behind the middle), the hind 

 angles well defined, the base is gently bisinuate and consequently 

 but little lobed hindward in the middle. The elytra are scarcely 

 wrinkled transversely, their lateral fringe being normal, their 

 apical membrane very well-defined. The whole upper surface is 

 strongly and coarsely, but not closely, punctured (the clypeus 

 more closely, the pygidium more feebly, than the rest) ; the punc- 

 tures so spaced that about 10 or 12 of average distance would 

 occupy the middle line down the prothorax. The hind coxae are 

 a little shorter than the metasternura and decidedly longer than 

 the 2nd ventral segment. The puncturation of the under surface 

 is strong and somewhat even, but in all parts becoming less close 

 towards the middle. The ventral series consist of fine hairs and 

 are but little conspicuous. The laevigate antero-internal space on 

 the hind coxsb is but feebly defined. The hind femora are 

 moderately wider than the intermediate, their inner apical angle 

 rstrongly defined. The three external teeth of the front tibia? are 

 very strong and sharp, the uppermost being about half the size of 

 the 2nd. The hind claws are minutely bifid, the produced piece 

 of the basal portion being much thicker than, and about as long 

 as, the apical piece.
