In the male, besides the impressions on the head and 

 thorax, the posterior margin of the dorsal plate of the

Ohs. — I have not thought it necessary to adopt the 

 name of H. Thomsoni which has been proposed for this

A dark- coloured, rather narrow and elongate species, 

 with the thorax distinctly narrower than the elytra, and 

 scarcely transverse; head, thorax and elytra rather dull. 

 The antennse are black, rather long, scarcely thickened 

 towards the apex ; joints two and three of about equal 

 length, four rather small, about as wide as three, and 

 about as long as broad, joints five and six each about as 

 long as broad, seven to ten, in the male nearly or quite 

 as long as broad, in the female transverse, but not strong-

 head is scarcely narrower than the thorax, rather long, 

 the sides straight behind the eyes, then rounded at the 

 posterior angles, finely and indistinctly punctured, but

 and sometimes indistinctly impressed in the male. The 

 thorax is considerably narrower than the elytra, a fourth 

 broader than long, slightly narrowed behind, finely and 

 not densely punctured, and not shining, with a short long-
