SYNOPSIS OF THE GENUS CHLOROTETTIX 11 



Vertex a little longer on middle than next the eye, bluntly 

 angulate. Face gradually, somewhat convexly narrowed to 

 clypeus which is broadest at apex. Pronotum with anterior 

 margin strongly curved to half its length, side margins very short, 

 posterior border emarginate. Elytra long, exceeding tip of 

 abdomen. 



Color: Pale green, vertex with a median brown line on posterior 

 portion, ocelli margined with bright green, margin as seen from 

 above with a darker blotch either side of apex, formed by the 

 darker color of the front extending on to the vertex. Pronotum 

 with disc and posterior portion darker, basal angles of scutellum 

 dark brown. Elytra washed with fuscous, a dark fuscous stripe 

 composed of three rather distinct lobes, extending along the 

 suture. In fresh specimens the color is bright with a red tint, 

 becoming dull in preserved material. Clypeus and tarsal seg- 

 ments marked with fuscous. 



Genitalia: Last ventral segment of female twice as long as 

 preceding, lateral angles rounded, posterior margin broadly, 

 deeply notched, more than half way to base, the sides of which 

 are dark brown. Male valve broad, almost transverse and trun- 

 cated posteriorly, plates broad and long, convexly narrowed to 

 rounded tips, exceeded by pygofers; a groove parallel to outer 

 margin, extending from base two- thirds the length of each plate. 

 Outer margins clothed with spines. 



The type specimens (author's collection) of this species were 

 collected in Tennessee from Canebrake (Arundinaria tecta) where 

 they occur in great numbers, but the species was not collected 

 from any other plant. Although having been reported only from 

 this state, its distribution no doubt corresponds with the distri- 

 bution of the food plant mentioned. Paratypes in Osborn 

 collection. 



Chlorotettix occidentalis n. sp. 



(Figs. 8: a, b.) 



Resembling stolatus, rather long and narrow, but with the 

 vertex shorter and genitalia distinct. Length, 7 mm. 



Vertex subangulate, almost one- third longer at middle than 

 next the eyes, more than twice as wide as long; ocelli one-third 

 the distance from the eyes to apex. Face longer than broad, 

 clypeus broad, apex truncate, antennal pits unusually deep.
