Very distinct from all other species known to me except 

 H. siccus, Blackb., whicb it resembles rather closely. Joint 

 3 of its antennae much more elongate readily distinguishes it, 

 however, from siccus, as also its puncturation notably coarser, 

 pro thorax with sides and hind angles more rounded, longer 

 basal joint of hind tarsi, etc. The hind coxae leave more than 

 usual of the 1st ventral segment exposed, but are very little 

 shorter than the metasternum. The trilobed outline of the 

 head is feebly developed and not divided, the middle lobe 

 about three-quarters of a lateral lobe in size. The pronotum 

 is fringed with erect hairs in front.
