A species with rather long antennae, somewhat spar- 

 ingly furnished with exserted hairs, its head and thorax 

 with a dull almost brassy appearance, the elytra of a dull 

 brownish colour. The antennee are longer than the head 

 and thorax, scarcely thickened toward the apex, of a 

 blackish colour, obscurely pitchy at the base ; joints two 

 and three rather long, three a little the longer, four to 

 nine as long as or rather longer than broad, ten scarcely 

 shorter than broad; eleventh joint rather long, about as 

 long as the two preceding together. Head narrower 

 than the thorax, rather broad in proportion to its length, 

 rounded behind the eyes, rather convex above, dull, 

 finely and pretty closely but distinctly, even rather 

 roughly, punctured. The thorax is a little narrower than 

 the elytra, its breadth about half as great again as its 

 length, the sides a little narrower at the anterior than at 

 the posterior angles, the sides gently rounded in front, 

 then nearly straight behind, distinctly, moderately closely, 

 rather roughly punctured, the sides with two or three 

 exserted hairs, with a fine longitudinal channel in the 

 middle in front of the scutellum, sometimes extending 

 the whole length of the thorax, sometimes only half-way. 

 The elytra are of an obscure brownish colour, about one- 

 third longer than the thorax, rather finely but distinctly, 

 closely and somewhat rugulosely punctured. The abdo- 

 men is black and shining, distinctly narrowed towards 

 the apex, segments two to four finely and rather closely 

 punctured, fifth segment rather more sparingly punc- 

 tured, sixth very finely and sparingly punctured, the 

 sides and apex furnished with distinct rather long out- 

 standing set«. The legs are yellow ; the middle and 

 posterior tibiae furnished each with two fine exserted 

 setge, one short, just below the knee, the other longer, a 

 little more than half-way down. 



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

 seventh abdominal segment has the external angles more 

 acute than in the female.
