our representatives, to such a degree indeed that these could not 

 be advantageously separated without inspecting the original type. 



As represented by nigritulum, the genus has the body rather de- 

 pressed above, feebly cuneiform, with the head short and almost en- 

 tirely enclosed within a subtubulate extension of the prothorax, the 

 eyes small, flat, coarsely faceted and in great part inferior, not visible 

 from above but widely separated beneath. Beak short but slender, 

 feebly arcuate, parallel, inserted at an angle with the surface of the 

 front, so that it is distinctly separated from and very much nar- 

 rower than the head. Antennae inserted quite distinctly behind the 

 middle, the scrobes nearly horizontal, not attaining but directed 

 upon the eye; scape short, clavate ; funicle slender, T -jointed, the 

 basal joint rather longer than the next two ; second to seventh 

 feebly increasing in thickness, equal in length, subquadrate ; club 

 as long as the preceding four joints, narrowly fusiform, polished, 

 sparsely setose, not annulate. Scutellum distinct. Prosternum 

 flat ; anterior coxae remote, separated by fully their own width ; 

 intermediate one-half more widely separated. Metasternum long. 

 Legs short, slender ; tibiae without internal spur, the uncus well 

 developed ; tarsi short, the third joint feebly dilated, the fourth 

 about as long as the preceding three combined. 



The three species, which it is necessary to include at present 

 within the genus, may be recognized as follows : — 



Prothorax truncate laterally at apex, remote from the eyes. 



Body parallel, ferruginous, densely but coarsely pubescent, the pronotum 

 coarsely, subconfluently punctate, the elytral series coarse and approxi- 

 mate er rans 



Body subcuneate, more convex, black, much less pubescent, the pronotal 

 punctures much smaller, distinctly defined ; elytral series not impressed, 



the intervals wide nigritulum 



Prothorax partially concealing the eyes at the sides : beak not distinctly sepa- 

 rated from the head by a transverse impression conic Hill 



H. conicnm must certainly constitute a genus distinct from that 

 including errans, if the characters given by LeConte are correct 

 (Trans. Am. Ent. Soc, VIII, p. 218), and the probabilities are 

 that each of these species will ultimately become the type of a dis- 

 tinct genus. 



H. nigritulum n. sp. — Black, the elytra somewhat shining, legs, an- 

 tennae and apical parts of the prothorax piceous-brown, vestiture very sparse, 

 consisting of erect setiform scales, especially visible on the beak and toward
