This species is easily recognizable by the characters cited 

 in the tabulation. The labrum (viewed as part of the out- 

 line of the head) is so decidedly concave that there can be 

 no hesitation about referring the insect to Group IV. rather 

 than to any of those groups having the outline of the head 

 trilobed. The female is a little more strongly punctured 

 than the male.

The claws of this species are somewhat intermediate be- 

 tween appendiculate and bifid ; a note regarding them will 

 be found under Group III. In Group IV. it is quite easily 

 recognizable by the characters cited in the tabulation. If its 

 claws were regarded as bifid it would stand in the tabulation 

 of Group III. beside H. granntn, Burm., from which, inter 

 alia mult a, its very different labrum separates it widely.
