Form: Larger than following species, broad. Length, female, 7.25 to 

 8 mm.; male, 5.5 mm. Vertex of female about as long as width across the 

 eyes, broadly rounded apically and foliaceous. Vertex of male about two- 

 thirds as long as basal width between eyes, rounded apically, not at all 

 foliaceous. Pronotum twice as wide as long, posterior margin emarginate 

 in front of scutellum, with distinct humeral margins. Elytra long, leav- 

 ing only tip of ovipositor exposed and exceeding the abdomen in the male. 



Color: Greenish or yellowish-green. Vertex with two converging red 

 lines which start from near the eyes. Pronotum with median red line on 

 posterior half and a pair of converging lines which start from the inner 

 angle of the humeral margin and extend across to the anterior margin to 

 points that divide the distance between the bases of the lines on the 

 vertex into equal thirds. Scutellum either unicolorous or with three faint 

 yellow stripes. Elytra either unicolorous or with nervures slightly 

 orange-yellow. 



External genitalia: Female, last ventral segment longer than preced- 

 ing, truncate posteriorly; pygofers acutely tapering posteriorly, exceeded 

 by ovipositor. Male, valve small, rounded, plates broad at base, tapering 

 to long acute tips, margins with few spines near the base ; pygofers acute 

 apically, slightly longer than plates, covered with coarse spines. 



Distrihntion: Collected in Labette county. 



Hosts: Probably a grass feeder.

Form: Smaller than vulnerata. Length, 5 to 6.5 mm. Vertex about 

 as long as basal width, shorter in the male, acutely pointed, not at all 

 foliaceous. Pronotum about twice as broad as long, narrowed ante- 

 riorly, humeral margins distinct, posterior margin slightly concave. 

 Elytra long, reaching ovipositor in female, exceeding abdomen in male.
