vertex yellowish mottled with brown and with two black spots at 

 apex. Vertex rounded in front. Elytra very dark brown. 

 Length 5-5.75 mm. 



A shrub-feeding form originally described from specimens col- 

 lected by Dr. W. E. Britton in Connecticut. At present the known 

 distribution is much greater.

A common dark brown species with an oval yellow "saddle" 

 area on middle of elytra and a broad transverse yellow band on 

 posterior portion of pronotum. Vertex rounded, yellow, apex 

 with a pair of large black spots. Length 5-5.5 mm. 



A common form in pastures and often taken from shrubs. It 

 may be a cosmopolitan feeder, and breeding records will perhaps 

 show that to be the case. This is one of our very common forms, 

 and is of economic importance throughout the summer.
