LAWSON: KANSAS CICADELLID^E. 159 



outer membrane whose posterior margin is then lobed, the middle one 

 being smaller than the lateral lobes; pygofers rather narrow, broadest 

 at the middle, slightly exceeded by the ovipositor, and spined on distal 

 half. Male, last ventral segment as long as preceding, posterior margin 

 concave; valve very small, rounded posteriorly; plates broadly triangular, 

 acute at tips, few spines on margins, exceeded by the basally broad, 

 acutely-tipped, long bristled pygofers. 



Distribution: Collected in Douglas and Pottawatomie coun- 

 ties. 



Hosts: Van Duzee took this species from "grass and weeds 

 near the borders of a low, swampy wood."

Deltocei'lahis punctatus Van D., Cat. Hemip. N. A., p. 650, 1917. 



Form: Short and rather robust. Length, 2.5 to 3.5 mm. Vertex 

 slightly wider than long, disc sloping, apex obtuse. Pronotum longer than 

 vertex, not twice as broad as long, lateral margins very short, humeral 

 margins long, rounding with slightly emarginate posterior margin. 

 Elytra long and narrow, exceeding abdomen and overlapping apically, or 

 short and broad, reaching sixth abdominal segment, venation indistinct. 



Color: Practically uniformly brown; vertex with two large black 

 spots, dark median longitudinal line and ocelli and two apical spots red- 

 dish. Black abdomen showing through elytra. 



External genitalia: Female, last ventral segment very long, sides 

 broadly rounded to truncate posterior margin which has a slightly ex- 

 cavated median portion; pygofers broad apically, spiny, equalling or 

 slightly exceeded by the ovipositor. Male, last ventral segment shorter 

 than preceding, slightly concave posteriorly; valve very broad, broadly 

 rounded posteriorly, three times as broad as long; plates broad basally, 

 spiny margins concavely narrowing to acute tips, two and one-half times 

 the length of the valve; pygofers broad at base, acute and long-bristled 

 apically, equalling the plates. 



Distribution: This species has not yet been taken in the 

 state but should occur here, at least in the northeastern portion. 



Hosts: Osborn and Ball took the type specimen on Sporo- 

 bolus.
