Foi-m: Females long and oval, males smaller, resembling a long- 

 headed Deltocephalus. Length, females, 7 mm.; males, 5 mm. Female, 

 head not quite as long as width across the eyes, margin foliaceous. Pro- 

 notum over twice as broad as long, lateral margins long, posterior angles 

 slightly produced, posterior margin slightly emarginate medially. Elytra 

 short, covering first abdominal segment. Male, vertex roundingly tri- 

 angular, one-third broader than long, margin not at all foliaceous. 

 Elytra narrow and long, much exceeding abdomen. 



Color: Females, straw colored, abdomen with narrow median fuscous 

 line and four, broader, lateral lines which are bordered with fuscous 

 lines. Male, milky white, often with five fuscous stripes on vertex and 

 pronotum. Broad, whitish nervures of elytra thickly margined with 

 fuscous dots. 



External genitalia : Female, last ventral segment slightly longer than 

 preceding, posterior segment broadly emarginate, with very small median 

 lobe ; pygof ers widest at about one-third the distance from their base, then 

 tapering to acute apex which equals the ovipositor. Male, valve large, 

 triangular; plates broad at base; together forming a triangle about as 

 long as broad, margins straight, armed with a row of stout spines; 

 pygofers small, much exceeded by the plates. 



Distribiition: Should occur in western Kansas. 



Hosts: A grass feeder, but definite host unknown.

Form: Intermediate between Dorycephalns and Spangbergiella. 

 Rather large, flat forms, with smaller males. Length, female, 10.5 to 13 

 mm.; male, 7 to 8 mm. Female, vertex about as long as width across 

 eyes, slightly narrowed in front of eyes, then widening to spoon-shaped 

 tip which is quite foliaceous and slightly reflexed. Pronotum over twice 

 as broad as long, lateral margins long and parallel, posterior margin con- 

 cave in front of scutellum. Scutellum broad and short. The elytra may 

 be short, leaving last three segments of abdomen exposed, or long, expos- 

 ing only the pygofers. In the smaller long-winged forms, the vertex does 

 not widen in front of the eyes and is shorter. Ovipositor is long and 

 exserted. Male, vertex not as long as width across eyes, more acute 

 anteriorly and not as foliaceous as in the females.
