the middle, its base about half again as wide as its front which is 

 lightly emarginate with very feebly produced angles ; the sides 

 diverge strongly from the apex to the middle where they are 

 ix)unded and whence they converge slightly to the base with which 

 their hind angles are almost rounded off; the base is scarcely 

 distinctly bisinuate or lobed, but is almost evenly rounded all 

 across. Elytra with no trace of striation except a fairly defined 

 sutural stria ; their transverse wrinkling scarcely perceptible ; 

 lateral fringe feeble and not continuous round apex which has a 

 scarcely noticeable membranous border. The puncturation of the 

 upper surface resembles that of H. testaceus, Blackb., (Sect. I.), but 

 is feebler except on the head. Hind cox^e about as long as meta 

 sternum, the puncturation of both being feeble and sparse (especially 

 in the middle). The ventral segments are scarcely distinctly 

 punctulate. The ventral series consist of long erect hairs and are 

 very conspicuous, but obsolete in the middle. The hind femora 

 are not very much wider than the intermediate and have their inner 

 apical angle very feeble. The lower two teeth of the anterior 

 tibiae are very strong and sharp, — the uppermost tooth is obtuse 

 and subobsolete.
