 part with knees, tibiae and tarsi more or less darkly brown. 



Head much broader than pronotum, fully as broad as elytra, with 

 aense and rather coarse, anteriorly rugous punctation, with two rather 

 deep forehead grooves, separated by a flatly convex interval; antennae 

 fine; pronotum before the middle much narrower than elytra, hardly as 

 broad as long, narrowing posteriorly, with coarse and very dense, some- 

 what rugous punctation, occasionally with a feeble or only suggested 

 groove in middle-line. Elytra are most often distinctly longer than 

 pronotum, with very coarse and dense punctation, the punctation is coars- 

 er, but hardly as dense, and less rugous than in the two preceding spe- 

 cies, inasmuch as the punctures are distinctly separated; abdomen at 

 sides with rather robust and dense, along the middle and posteriorly 

 finer and more isolated punctation, its first four free dorsal joints 

 with a fine carina anteriorly in middle-line; legs slender, hind tarsi 

 scarsely as long as tibiae. L. 5 mm. 



In the o the hind femora are hardly more robust than in the p , 

 but on inner side at base with long hair, the middle-tibiae at tip on 

 inner side armed with a small and short, yet distinct spine; metaster- 

 num flatly impressed, with sparse long hair; abdominal first four ven- 

 tral joints at middle feebly flatly depressed, the depression bounded 

 on each side with a row of long, dense, incurved, grayish-yellow hair; 

 the fifth ventral joint is more deeply impressed than the preceding, the 

 impression at bottom specular, with a short, somewhat obtuse carina in 

 middle-line, its side-margins at middle prominently dentiform, but pos-
