680 REVISION OF THE GENUS HETERONYX, 



ventral segment, their postero-external corner sharply rectangular, 

 they and the metasternum being punctured rather closely and not 

 very strongly on the sides, — much more sparingly and strongly 

 towards the middle, the former with a distinct smooth antero- 

 internal space. The ventral segments are punctured a little more 

 finely than, and about as closely as, the sides of the metasternum 

 but their sculpture is a little feebler and less close in the middle ; 

 the ventral series consist of fine hairs but are fairly conspicuous. 

 The hind femora are not much wider than the intermediate, their 

 inner apical angle feebly defined. The three external teeth of the 

 anterior tibise are wide and sharp but not very long, the upper- 

 most being less than half as large as the intermediate, the tibial 

 outline from its base to the apex of the uppermost tooth being 

 straight. The hind claws are exceptionally long, the basal piece 

 being quite twice as long as the apical and having its apex pro- 

 duced in a distinct process, which however is less than half as 

 large as the apical piece. The basal joint of the hind tarsi is not 

 much more than half as long as the 2nd joint.

The trilobed appearance of the outline of the head is very feebly 

 defined owing to the slight convexity of the upper edge of the 

 Jabrum which makes the latter appear (unless viewed from very 

 far back) as a wide truncate projection from the front ; viewed 

 from very far back {i.e. very obliquely, almost along the surface of
