180 Sail — Descriptions of JVeio Tree Hoppers. 



Dorsal hump sloping up from both front and rear, crest round inr, 

 highest just in front of the middle, hump occupying scarcely two-fifths 

 of the pronotum from the humeral angles back. Humeral angles short 

 and blunt, about two-thirds the length of the eye. , 



Color. — Face and pronotum pale yellow very slightly washed with brown 

 in the female, and with a definite brown shade in the male, median 

 carina alternately light and dark before the hump. Hump rich testa- 

 ceous with a few light spots on the sides, a definite light mark at the 

 base in front, which may extend up onto the carina, and the whole pos- 

 terior margin light. This latter light spot extends down on to the pro- 

 notum and connects with an irregular transverse light band about half 

 way to ap< x. Each side of this band is an irregular testaceous band, 

 the anterior one' connected with the testaceous hump. A pair of spots 

 above the eyes and the apex of elytra brownish fuscous. 



Described from six specimens from Ames, Iowa, collected by the 

 author, one from Onaga, Kansas (Crevecoeur), and a pair from Arkansas 

 (McEl fresh). The Iowa specimens were all taken from the smaller 

 branches of the red oak. 



Telamona compacta, sp. nov. Plate I, figs. 5, and 5a. 



A small, compact, testaceous and white species with a low almost quad- 

 rangular hump. Length 8-9 mm.; width 4.3 mm. 



Dorsal hump sloping up from above the humeral angles, highest just 

 back of the rounding anterior angles, crest straight or nearly so, sloping 

 posteriorly, the posterior margin very slightly sloping and subangulate 

 with the crest. Hump extending slightly more than half the distance 

 from the humeral angles to the very short and blunt apex. Humeral 

 angles short and blunt, about two-thirds the length of the eye. 



Color. — Rich testaceous marked with creamy white, as follows: a num- 

 ber of small spots just above the face, an angular or stellate spotinfioat 

 of the hump, the posterior margin of hump and a transverse band half 

 way between there and apex of pronotum. Usually a spot or two on 

 lateral face of hump and one on margin below hump. Elytra smoky 

 testaceous with a hyaline band across the base of the apical cells. 



Described from a pair from Ames, Iowa, collected by the author, and 

 two females from Arkansas collected by F. M. McElfresh. The pair 

 from Iowa were taken from a patch of mixed oaks. 



Telamona ehrhorni, sp. nov. Plate I, figs. 4, and 4a. 



Form of sinuata nearly but smaller. Dark fuscous brown prettily or- 

 namented with light. Length $ 8 mm.; width 4.5 mm. 



Dorsal hump long, rather high, rising on a line with the humeral angles, 

 anterior margin straight, inclined backwards, crest roundingly angled in 

 front, sloping posteriorly, slightly emarginate on the posterior half. Pos- 

 terior margin short, inclined, rounding to the pronotum. Hump occupy- 

 ing nearly three-fifths of the distance from the humeral angle to apex of 

 pronotum.
