 and a half times as broad as long, the 11th stout, the apex rounded. 

 Thorax more than half as broad again as long, the sides evenly

 punctured, finely pubescent. Abdomen parallel, pitchy, lighter 

 at the base, very finely and closely punctured and pubescent 

 throughout.

Head black, thorax and abdomen pitchy, moderately shining, 

 the elytra fusco-testaceous, the first two joints of the antennae 

 obscure testaceous ; legs testaceous. Length 1 mm. 



A small parallel species, with pitchy thorax wliicli is not so broad 

 as in the preceding and Avith finer puncturation. Head black,

 the apex itself with a small cmargination, the lateral teeth shorter,
