Rare. The only station for the species known in the basin "is one small 

 clump of young sycamores in the bed of upper Six Mile Creek. Nymphs 

 and adults have been collected here, but the data obtained have not been 

 sufficient to determine the life history. Both nymphs and adults feed 

 on the petioles of the smaller leaves. The species is very active and 

 flies well and for considerable distances, but eventually returns to the 

 same host from which it was disturbed. 



The species may be recognized by the uniform ferruginous color and 

 by the ver}'- well-developed humeral angles. 



Technical description. — Of the same general form as T. ampelopsidis, but smaller and 

 differing in color; ferruginous brown with yellowish fascia over metopidium; posterior process 

 exceeding tips of tegniina; tegniina brownish hyaline, tips slightly clouded. 



Head uniform yellow-green, irregularly punctate, pubescent, sculptured; eyes prominent, 

 light brown; ocelli prominent, protruding, brown with white margins, i^earer to each other 

 than to the eyes; clypeus flat, tip extended. 



Pronotum coarsely punctate; metopidium convex, lower anterior margin yellow, smooth 

 area above eyes, median dorsal carina prominent; humeral angles much produced, triangular, 

 sharp; dorsal crest much higher before than behind, anterior margin vertical, dorsal margin 

 sloping backward, posterior margin .short; posterior process long, slender, acuminate, extend- 

 ing beyond tips of tegmina. 



Tegmina brownish hyaline, bases and costal areas sparingly punctate, tips faintly clouded 

 with brown. Undersurface of body and legs yellowish; tarsi yellow-ferruginous; claws 

 fuscous. 



Length 10 mm.; width 6.5 mm.

Common thruout the basin on red oak and linden and found during the 

 entire summer. The species is very close to T. reclivata, from which it 

 can be separated by the brown oblique marking extending from the tip 

 of the crest to th(^ lateral margin of the pronotum. 



The adults are most commonly found on the smaller branches and the 

 twigs, a habit noted by Dr. Ball in his originalr description. The nymphs 

 have not been distinguished from those of T. reclivata, with which they 

 are often associated. 



Technical description. — Grayish yellow with sides of crest and line from crest to margin 

 of pronotum brown; apex of posterior process broadly brown; tegmina smoky hyaline, bases 

 sharply punctate with black, apices brown. 



Head wider than long, nearly vertical, lemon yellow thickly punctured with brown, punctures 

 larger and darker near eyes than in center; entire face sculptured; clypeal suture deep; eyes 

 brown margined with paler; ocelli large, pearly, nearer to each other than to the eyes; clypeus 

 extending well below inferior margin of cheeks, tip hirsute.
