feet pale yellowish. 
Length one- tenth of an inch. 
At first view it resembles prommus, Say^ both asl^espects

the dorsal line distinct, terminating on the basal margin in 
an impressed puncture, on each side of which is another 
rather smaller puncture ; basal lines much dilated, deeply 
undulating the posterior edge of the thorax : elytra w\i\\ a*

The dilated basal thoracic lines deeply indenting the pos-

will readily distinguish this species. At first view it resem-
