44 The Ohio Naturalist. [Vol. IV, No. 2, 



Described from numerous specimens of both sexes collected at 

 Columbus, Ohio, in 1903. 



This species resembles viridis Ball, but is larger, with more 

 pronounced coloring, especially the black spots of the front. The 

 vertex is less elongate and genitalia different. 



While the root inhabiting habit is unusual in this family there 

 are, of course, abundant instances in other homopterous families,^ 

 as Aphidse. Membracidae and Cercopidae.
