Belonging to the clitellarius group but with "saddle" spot of 

 yellow on the dark brown elytra more linear and elongated, 

 extending from apex of scutellum to tip of clavus. Costal margin 

 broadly pale to near apex. Vertex obtusely angled, yellow, apex 

 with two black spots. A yellow transverse band across posterior 

 half of pronotum. Length 5.5-6 mm. 



Rather abundant in cool moist woods on Impatiens in the coarse 

 grass-fern association during August, but occurring only in thick 

 woods.

Rather large robust species with vertex angled, brownish with a 

 greenish tint seldom with definite markings. Elytra dark, veins 

 paler. Female segment shallowly emarginate posteriorly. Length 

 6 mm. 



A typical northern form apparently feeding on shrubs from 

 which it is usually taken. Reported as occurring on birch and

A very common grass-feeding species throughout the summer in 

 low wet pastures, and meadows. Abundant to such extent that 

 it is of economic importance.
