 Resembles 12-pnnctatus in form and sculpture. Differs by having the 



hind femora wholly piceous or dark brown, the hind coxal plates broadly 

 rounded, and the el,ytra suhtruncate at apex. The sutnral black line is 

 narrowed on basal half and the median subsutural spot is confluent with it 

 to form a rather large irregnhu' blotch. Length 3.5-4 mm.

 as well as the other species probably passes the wiiiter as imago.
