more so than in H. jnceus, Blanch.), their lateral fringe normal 

 their apical membrane obsolete. The hind coxae are quite as 

 long as the metasternum, the puncturation of both these being 

 decidedly close and fairly strong at the sides, while in the middle 

 of the latter and about the antero-internal part of the former it is 

 coarse and sparse. The ventral segments are almost Isevigate, the 

 ventral series being very conspicuous and consisting of stout bristle- 

 like hairs. The hind femora are very wide (quite double the inter- 

 mediate), their inner apical angle obtuse and little prominent. 

 The lower two external teeth of the front tibisB are very strong 

 and sharp — the uppermost is represented by a mere nick on the 

 outline. The apical piece of the hind claws is evidently less than 

 half as large as the basal piece and decidedly larger than the 

 produced apex (which is truncate at the end) of the latter. 



N.B. — The intermediate joints of the antennae are so crowded 

 together, small, and obscure, that they are very difficult to count 

 with certainty.

The head closely resembles that of H. nasutus, Blackb. The 

 prothorax is J again as wide as long, its base scarcely | again as 

 wide as its front which is moderately concave with angles but 

 little produced ; the sides are gently arched ; the hind angles 

 viewed from above appear fairly defined but obtuse ; the base is 

 lightly bisinuate, being moderately lobed in the middle. The 

 puncturation of the upper surface is not deep but rather coarse,
