 the rounding inner angles; pygofers about as long as the plates, narrow, 

 and covered with numerous very large hairs.

 Elytra with black spot on humerus, on some of the cross veins and also in 

 some cells. 



External ge nit alia: Female, last ventral segment broad and long, 

 posterior margin sinuate, lobe on median third with a median notch;

Form: This species varies very greatly in size. Length of females 6 

 to 11 mm., males 5 to 9 mm. Vertex produced more than in other mem- 

 bers of the genus, about three times as long medially as next the eyes 

 and almost as long as the pronotum. Pronotum twice as bread as long. 

 There are long- and short-winged forms in both sexes. In the long- 

 winged females the elytra just exceed the abdomen; in the short-winged 

 forms they are exceeded by the abdomen. The elytra of the long-winged
