1234 REVISION OP THE GENUS HETERONYX, 



The elytra are punctured considerably more strongly than the 

 prothorax ; their transverse wrinkling is fairly defined, their 

 apical membrane obsolete ; the set?e are placed more or less in 

 rows on their surface and spring from minute pustules. The hind 

 coxse are very fully as long as the metasternum. On the under- 

 surface the metasternum is punctured fairly strongly and not very 

 closely, the hind coxse more feebly and. more closely (with a 

 distinct Isevigate antero-internal space) the hind body very finely. 

 The ventral series spring from conspicuous pustules and consist of 

 stoutish hairs. The hind femora are much wider than the inter- 

 mediate and have their inner apical angle scarcely defined. The 

 basal joint of the hind tarsi is much longer than the 2nd joint (a 

 very unusual character). The 3 external teeth of the front tibiae 

 are moderately strong but not very sharp. 



Extremely like H. granulifer^ Blackb., but differing from it 

 widely in respect of structural characters.

This is another species that seems a little to hover been Sections 

 II. and III., the labrum and clypeus being very similar to those of 

 H. setifer except that the latter is scarcely at all emarginate in 

 front. Like H. setifer it shows no indication (from any point 

 of view) of the outline of the head being trilobed. The clypeus 

 is very distinct from the rest of the head, from which it is 

 separated by an almost straight suture, its front being distinctly 

 reflexed and scarcely ODiarginate, the labrum projecting forward 

 considerable in front of it, but not quite rising to its level. The
