series are well defined, consisting of stout fulvous hairs. The hind 

 femora are a good deal wider than the intermediate, their inner 

 apical angle being scarcely distinct. The three external teeth of 

 the front tibise are strong but rather blunt, the uppermost small, 

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

 is straight. The apical piece of the hind claws is not very much 

 shorter than the basal which is distinctly produced at the apex, 

 but its produced apex is much smaller than half the apical piece. 



Apart from colour this species bears much resemblance to H. 

 sjKtrsus (from the same locality) but it is a more robust, larger 

 insect, with the puncturation (especially on the prothorax) larger, 

 shallower, and less sparing, and the produced apex of the basal 

 piece of the hind claws much smaller.

The structure and sculpture of the head do not differ in any- 

 noticeable manner from those of the preceding two species. The 

 detailed description of the prothorax of H. vacuus will apply to 

 this species, but the puncturation is very evidently coarser. The 

 elytra are punctured slightly more coarsely and closely than the 

 prothorax, with a somewhat squamose appearance and a good deal 

 of transverse wrinkling, — especially towards the sides ; they have 

 no defined striation ; their lateral fringe is normal and their apical 

 membrane narrow but distinct. The hind coxae and metasternum
