LAWSON: KANSAS CICADELLID^. 213 



Color: Nearly uniformly yellowish-green. Ocelli brown or black, a 

 brown curved line from each to the apex. Elytra subhyaline, tips smoky, 

 nervures bright yellow to brown. Face yellow, with brown arcs and with 

 sutures of front black. 



External genitalia: Female, last ventral segment half longer than 

 preceding, broadly but not deeply emarginate medially, having distinct 

 lateral angles; pygofers long and narrow, exceeded by ovipositor, bristly 

 on posterior half. Male, valve broad, triangular, very obtuse apically; 

 plates large and broad, margins armed with very long, white spines, con- 

 vexly tapering to subacute apices; pygofers very characteristic, viewed 

 laterally they are long and triangular, tapering to long and slender apex 

 which terminates in a chitinous point, just exceeding plates, and bearing 

 a tuft of white bristles just before the middle. 



Distribution: This species has not yet been collected in Kan- 

 sas, but undoubtedly occurs in the eastern part of the state. 



Hosts: DeLong collected this species from Elymus virgini- 

 ciis and from other tall grasses,

Form: Smaller than the preceding species. Length, 3.5 to 4 mm. 

 Vertex about half wider than long, broadly rounding apically, disc sloping, 

 rounding obtusely with front. Pronotum twice as broad as long, anterior 

 margin strongly convex, lateral margins very short, humeral margins 

 distinct, posterior margin slightly emarginate. Elytra typical of the 

 genus though not as long as in the two preceding species. 



Color: Grayish or brownish; vertex whitish, tinged with orange, with 

 a wavy black line on each side from apex to ocelli, two brown median 

 lines bending at right angles just before the middle, and two brown 

 circles on the disc. Pronotum gray, with six white spots along the an- 

 terior margin, two small black spots back of each eye, and five faint 

 longitudinal lines. Elytra subhyaline, marked with brown and black 

 spots, nervures darkened apically. Front gray, with light median line 

 and arcs. 



External genitalia: Female, last ventral segment one-half longer 

 laterally than preceding, posterior margin strongly and angularly pro- 

 duced; pygofers long and narrow, exceeded by ovipositor, bristly medially 

 and apically. Male, last ventral segment as long as preceding; valve 

 broad and short; plates broad basally, the spiny margins concavely nar- 

 rowed to long attenuate tips which are slightly exceeded by the bristly 

 pygofers. 



Distribution: This species has not yet been reported from 

 the state, but probably occurs here. 

 Hosts: Various grasses.
