straight, projecting almost dircctlj' outward; dorsal crest regularly arcuate; 

 lateral semicircular inii)ression nearly obsolete; posterior process curving 

 slightly downward, not extending beyond tip of abdomen and reaching only 

 for a short distance beyond internal angles of tegmina. 



Tegmina entirely hyaline, somewhat wrinkled, bases lightly punctate. Legs 

 and undersurfaces of bodj' concolorous greenish. 



Length, S mm.; width, 4 mm. 



Internal male genitalia. Style very large when compared with 

 the otiier members of the genus, anterior process short, a small but 

 distinct knob to the connective, posterior portion extending straight 

 until considerably past the connective, then bending rather abruptl}^ 

 laterad and ending in a tip that on its mesal margin bears a number 

 of small but distinct teeth; connective very long and rather slender, 

 notched at base; cedagus, viewed laterally, small, with dorsal proc- 

 ess strongly humped, the ventral process with basal knob, then ta-

Distribution. Van Duzee records this species from Ontario, New 

 York, New Jersey, Pennsylvania, North Carolina, Ohio, Kansas, 

 Colorado, and Utah. In Kansas specimens have been taken in the 

 following counties: Cowley, Sumner, Bourbon, Cherokee, Chau- 

 tauqua, Douglas, Riley, Shawnee, Crawford, Miami, Linn, Neosho, 

 Rawlins, and Ottawa. It is thus seen to extend well over the state. 



Hosts. Funkhouser gives the following host list for this species: 

 Wild grape, locust, elder, willow, oak, hickory, pignut, raspberry, 

 sycamore, apple, and pear.

The following is the original description: 



This is so similar to the common Buffalo tree hopper that it will scarcely 

 be distinguished from it except by a practiced ej'e, although it is undoubtedly 

 a distinct species. It differs from that in having the horns much more short, 

 and the sides' of the thorax when viewed in front are not gradually curved out- 

 wards, but are straight or rectilinear, with the horns abruptly projecting from 

 the comer at the upper end of this line. The acute spine at the tip of the 

 thorax is also more long and slender. The thorax between the horns is slightly 

 convex. The dried specimen is of a pale dull j-ellow color freckled with faint 

 pale green dots and with a paler straw-colored stripe, quite distinct, upon the 

 angular sides of the thorax from each eye upward to the horn and from thence 

 to the summit of the thorax. 



Length of the female, 0.36. 



It was met with upon hickory bushes in New Jersey.
