length of 1, 2 and 4 subequal, each one-third shorter than 3. Front 

 lobe of pronotum granulate, its disk with a deep groove on basal half. 

 Length, 12—16 mm. 



Frequent throughout Indiana, July 14 — Oct. 27. In summer 

 occurs on foliage of various shrubs and herbs along roadsides 

 and pathways of open woods, both nymphs and adults being 

 especially common on that of Cratagus and wild rye in August ; 

 in autumn on boles of trees or crawling along the bare ground 

 in open places. Ranges from Ontario and New England west 

 to Wisconsin and Colorado and south and southwest to Kansas 

 and Arizona. Not recorded from the southern states. Van 

 Duzee records it as occurring in numbers on oak near Buffalo, 

 N. Y., and Hussey on hickory in Michigan.

Differs from Acholla mainly by the characters given in key, 

 the front femora being armed above with a single long spine 

 and both they and the tibiae beneath with two rows of shorter 

 ones (fig. 145, a) . The head is armed as there and the humeral 

 angles of pronotum are usually more acute. About a dozen 

 species are known, all from America, four of which occur in 

 the eastern states. The genus has been monographed by 

 Caudell (1901).
