and the front, and almost as near each other as the eyes, while 

 the fore wings are withont closed cells in the disk. The spe- 

 cies most injurious to the grape-vine is the Erythroneura vitis 

 Harris (Fig. 535). It is pale j^ellow, with two red lines on 

 the head, while the hinder edge of the thorax, including the 

 scutellum, the base of the fore wings, with a broad band across 

 their middle, are scarlet, and the wings are tipped with black. 

 In Jassus the species are larger than the foregoing, with 

 stouter bodies. The head is very broad and short, concave at 

 base, and the ocelli are placed between the eyes on the front, 

 which is broader than long, and the ovipositor is recurved. 

 Jassus irroratus Say is not uncommonly seen on herbage. 



The common JTelochara commioiis Fitch, a grass green sj)e- 

 cies, is found in great abundance in damj), grassy places, in 

 company with the yellow-legged, closely allied, Diedrocephala 

 .nolh'pes and Diedrocephala qiiadrhnttata Say, which lias the 

 vertex flattened :ind four scarlet stripes on the wings. In Tet- 

 tigonia the anteiuia^ are half as long as the body. T. bifida 



S a y is common in 

 gi-ass. In Cercopis the 

 prothorax is large and 

 hexagonal. 



The Clastoptera pro- 

 \teas of Fitch is a 

 common insect in blue- 

 berry fields and cran- 

 berry pastures. It is 

 sliort and thick, with a bright 3'ellow head, with a black band 

 on the front margin of the vertex, and a broader one on the 

 front, and a black dot near tlie apex of the elytra, while the 

 legs are yellowish white, and the tarsi are black. It varies 

 gi-eatly in its colors. In Aphrophora the head is of moderate 

 size, with two ocelli approximate on the crown of the head ; 

 tlie prothorax is trapezoidal and the posterior tibia? have two 

 teeth. A. quadrinotata Say is found on grape-vines.

 at once known by having only three distinct joints in the an- 

 tennie, and the two ocelli are placed beneath the eyes. The
