piceous brown with a broad median vitta extending onto the two basal 

 segments of the tergum ; lower surface and legs pale dull testateous ; meso- 

 notum with a large brown spot; tarsal spines tipped with black; abdomen 

 blackish brown, the sides of the venter varied with testaceous. Elytra 

 hyaline, with a conspicuous brown vitta from the base to the extreme apex 

 following the line of the second sector; first sector and the two first apical 

 nervures white, the others brown or mostly so; apical nervures four, the 

 interior forked. 



This species may be distinguished from its european congenors by its 

 glassy elytra marked with a conspicuous longitudinal vitta, by the uni- 

 formly testaceous inferior surface, and the absence of the black spots on the 

 cheeks. Described from two examples representing both sexes, taken at 

 Lancaster, N. Y. in August iS86. 



KELISIA CROCEA, n. sp. 

 Stenocranus sp. Osborn, Proc. Iowa Acad. vSci , 1, pt. 2, p. 127, iS^i. 



General appearance of Stenocranus dorsalis but smaller witii a wider 

 front. Length 4^ m. m. 



F"emale: Pale yellowish; a dorsal whitish vitta on the vertex pronotum 

 and scutellum, and a similar one on the face, broadest on the apex of the 

 front. Legs, pleural pieces and the margins of the abdomen paler. Elytra 

 whitish hyaline, with distinct white setigerous nervures. Eyes brown. 



Male: Color fulvous, at least in fully matured examples, with a paler 

 dorsal vitta covering the middle of the vertex, pronotum and scutellum, in 

 which is a white longitudinal line. Median carina on the front and a lon- 

 gitudinal vitta in each fova, whitish; pronotum paler; tergum usually black 

 with the margins and an irregular spot on the disc fulvous; venter covered 

 more or less by a blackish cloud; apex of the elytra with a fuscous cloud 

 which is intensified toward the inner angle, and extended somewhat along 

 the sutural margin. Eyes, claws and tip of the rostrum black. 



Iowa. Described from 5j and 3 j examples received from Prof. Her- 

 bert Osborn labeled "Ames, Iowa." In this species the front is broader 

 than in Stenocranus dorsalis; the elytra want the distinct brown line along 

 the second inner apical nervure ; the lateral compartments of the front are 

 whitish instead of black and the insect is somewhat smaller.
