436 REVISION OF THE GENUS HETERONYX, 



and somewhat even but becoming slightly less coarse and sparse 

 continuously from the clypeus hindward ; on the pygidium, how- 

 ever, it is decidedly faint and sparse. The elytra have no distinct 

 trace of striation ; their transverse wrinkling is well defined, their 

 lateral fringe normal, their apical membrane very obscure. The 

 hind coxae are not shorter than the metasternum. The ventral 

 series consist of stout bristles but are not very conspicuous owing 

 to the presence of numerous fine long hairs on the ventral seg- 

 ments, and they appear to be very deciduous only one of several 

 specimens before me having them in full complement. The meta- 

 sternum and hind coxae are punctured rather coarsely and closely 

 but not deeply, the punctures becoming sparser and coarser 

 towards the middle of the former and the antero-internal space of 

 the latter being Isevigate. The hind body is punctured very 

 similarly to the metasternum. The hind femora are very much 

 wider than the intermediate, the apex of their inner margin being 

 strongly but not sharply dentate. The lower two teeth on the 

 external margin of the front tibise are very strong ; the uppermost 

 is sharp and well defined but less than half as large as the second j 

 the edge of the tibia from its base to the apex of the uppermost 

 tooth is almost a right line. The produced apex of the basal 

 piece of the hind claws is stout and just about half as large as the 

 entire apical piece.
