A remarkably narrow elongate species, the pro thorax 

 unusually small in comparison with the elytra. Not much 

 like any other species known to me, though structurally near 

 collaris, Blackb., which, however, is very much smaller and 

 less elongate, with an unusually large prothorax, joint 3 of 

 antennae very short, basal joint of the hind tarsi as long as 

 the 2nd joint, etc. The prothorax of planiceps, measured at 

 the middle of the front margin, is very little narrower than 

 at the base, the sides converging somewhat in front of the 

 extremities of this line. The trilobed outline of the head is 

 fairly well developed, but scarcely divided, the middle lobe 

 about equal in size to a lateral lobe.

This species is not at all close to any other known to me 

 except the following species (H. ordinarius), from which, 

 however, it is quite easily distinguishable by, inter alia, the
