 D. pictus Osborn. (Fig. 11, 5.) 



Proc. Dav. Acad. Sci., x, 165, 1907. 



Allied to D. reft exits, vertex produced, acutely angled, a little 

 longer on middle than width between eyes. Pronotum with four 

 broad longitudinal dark stripes. Basal half of face black. Elytra 

 whitish, veins pale, broadly dark margined. Female segment 

 slightly concave, a rounded short median tooth with a black line 

 either side. Male plates rather long and narrowed to rounded 

 tips. Length 3.5 mm.

 type in New York and Pennsylvania. It is perhaps more widely 

 distributed.

Vertex broader between eyes than median length, bluntly angled, 

 a distinct white cross on the disc in well-marked specimens. Pro-

Homop. N. Y. St. Cab., 61, 1851. 



Rather short, vertex rather strongly angled, tip, two concentric

 and another across apex of elytra. Female segment broadly con- 

 cavely rounded. Male plates rather long and tapered to blunt tips. 

 Length 3.5 mm. 



A very abundant meadow species of economic importance 

 throughout the northern states from May to October. It often 

 feeds on the tall grasses and is able to live under a variety of 

 conditions.
