26 SYNOPSIS OF THE GENUS CHLOROTETTIX 



Color: Pale yellowish green, elytra greenish subhyaline. In 

 old specimens there is often a distinct yellow tint. 



Genitalia: Last ventral segment of female half longer than 

 preceding, lateral angles rounding, posterior border roundingly 

 emarginate, one-third the depth of the segment, sometimes 

 slightly notched in the middle, either side of which there is a 

 brown cloud. Male valve broad, slightly longer than the ultimate 

 segment, obtusely angulate; plates broad at base, roundingly 

 narrowing to a very obtuse, almost truncate, apex, together the 

 shape of a blunt pointed spoon, convex below with a marginal 

 fringe of coarse spines. 



Easily separated from any of the other species of the genus 

 by the male plates. The specimens from which the species was 

 described were collected in Kansas. Records show it has been 

 taken in Florida, Tennessee, Arkansas, Louisiana, North Carolina, 

 Texas and Missouri. The species is no doubt rather widely dis- 

 tributed throughout the south and middle west. Type in 

 collection of Dr. E. D. Ball.

Form and general appearance of lusorius slightly narrower and 

 without the mark on the vertex. Length, 7-8 mm.; width, 1.5 

 mm. Male slightly smaller. 



Vertex nearly flat on disc, rounding anteriorly, one-third 

 longer on middle than against eye, twice wider than long, front 

 convex, line between vertex and front distinct, ocelli prominent, 

 transparent, distant from eyes; elytra long and very narrow, 

 venation as in lusorius, indistinct. 



Color: Vertex pale yellow, sometimes with a greenish cast, 

 pronotum olive, the disc with a fulvous cast; elytra hyaline 

 green, with an iridescent fulvous tinge. 



Genitalia: Last ventral segment of the female very long, 

 truncate posteriorly or very slightly emarginate, the center with 

 a brown mark. Male valve as long as the last ventral segment, 

 the apex rounding, the margin notched at the middle, plates 

 rather narrow at base, rapidly roundingly narrowing to before the 

 middle, then extending as long attenuate finger-like points.
