212 Dr. Sharp's Revision of the 



AntennEe moderately slender^ scarcely thickened to- 

 wards the apex, pitchy or pitchy-black, the base some- 

 times indistinctly paler; joint three not quite so long as 

 two, four rather smaller than five, each of them about as 

 long as broad, six to ten each a little broader than long ; 

 eleventh joint about twice as long as the preceding one. 

 The head is slightly narrower than the thorax, black and 

 shining, very finely and indistinctly punctured. The 

 thorax is a little narrower than the elytra, about a third 

 broader than long, the sides a little rounded at the an- 

 terior angles, then neai-ly straight behind ; it is black and 

 shining, very finely and not closely punctured, its pubes- 

 cence is extremely fine. The elytra are about a third 

 longer than the thorax, brownish, often nearly black, 

 finely and closely punctured. The abdomen is black and 

 shining, segments two to four are finely and moderately 

 closely punctured, fifth very finely and sparingly punc- 

 tured, sixth almost impunctate. Legs rather dirty 

 yellow. 



In the male, the hind margin of the dorsal plate of the 

 seventh abdominal segment is distinctly emarginate ; the 

 ventral plate of the same segment is considerably pro- 

 duced, but little narrowed towards the hind margin, 

 which is nearly straight, with the angles rounded. 



Moderately common all over the country. 



Ohs. — This species is readily distinguished from H. 

 angusticoUis by its more shining head and thorax, the 

 latter of which is broader, and by its shorter elytra. Its 

 most marked character is the formation of the upper and 

 under plates of the seventh segment in the male.
