LAWSON: KANSAS CICADELLID^. 197 



Elytra whitish, heavily inscribed with brown nervures and ramose mark- 

 ings, lighter on costa, and suture with distinct ivory trilobate markings. 

 Face yellow, marked with brown irrorations and arcs. 



External genitalia: Female, last ventral segment broad and short, 

 roundingly narrowed posteriorly, posterior margin broadly excavated to 

 nearly one-half the distance to the base and with a median notch extend- 

 ing nearly to the base; pygofers broad, slightly exceeded by ovipositor, 

 apical half bristly. Male, last ventral segment longer than preceding; 

 valve narrow, triangular, about one-half wider than long, apex acute; 

 plates broad and short, submarginally spined, margins convexly rounding 

 to obtuse apices which extend beyond the valve less than the length of the 

 latter and nearly or quite equalling the short bristly pygofers. 



Distribution: Taken in Pottawatomie and Morton counties. 

 Hosts: The only host plant record is that given by De Long 

 who swept a single female from pasture gi'asses.

Form : Medium sized, semi-robust species. Length, 6 to 6.5 mm. Head 

 as wide as the pronotum ; vertex one-third longer on middle than next 

 the eye, two and one-half to three times as wide as long, broadly rounded 

 apically. Pronotum twice as wide as long, humeral and lateral margins 

 about equal in length, rounding into each other, posterior margins some- 

 what emarginate. Elytra broad and moderately long, flaring behind, 

 claval nervures parallel, not united by a transverse nervure. 



Color: Faintly light brown. Vertex, pronotum and scutellum yellow- 

 ish, irrorate with brown ; elytra whiter. Vertex with irregular black 

 markings on either side of the white apex, back of this a lighter area and 

 then irrorate with fulvous brown to the base. Scutellum with two light 

 spots on margin and at apex, and a dark spot on each margin. Elytra 

 finely and evenly inscribed with fuscous dots which fuse into lines costally 

 and apically. Face heavily irrorate with fuscous, black above. 



External genitalia : Female, last ventral segment vei-y long, slightly 

 narrowed posteriorly, posterior margin truncate, with a small median 

 notch between which and the lateral angles the margin is slightly con- 

 cave; pygofers not as broad as in preceding species, slightly exceeded by 

 ovipositor and sparsely spined. Male, valve very broad, triangular, with 

 obtuse or subacute apex; plates large, broad at base, narrowing rapidly 

 on basal third and then produced as parallel-margined, bluntly pointed, 

 divergent lobes which completely hide and exceed the pygofers. 



Distribution: Taken in Gove county only. 

 Hosts: Unknown.
