versely wrinkled. Elytra rather long and broad, usually vertical apically, 

 appearing to narrow the insect posteriorly. 



Color: Somewhat darker than cinereus. "Vertex yellowish-white, not 

 inscribed along most of anterior margin, but brown back of this. Pro- 

 notum and scutellum also yellowish-white, quite evenly inscribed with 

 fulvous brown, disc of pronotum often darker, tip of scutellum white. 

 Elytra milky-white, dotted with fine brown points, apically darker. Face 

 yellowish-white, marked with light brown. 



External genitalia: Female, last ventral segment twice as long as the 

 preceding, lateral margins strongly narrowed near apex to the obtuse 

 lateral lobes between which the posterior margin is slightly emarginate, 

 with the median portion produced and broadly and shallowly notched; 

 pygofers broad, widest at the middle, slightly exceeded by the ovipositor, 

 sparsely bristled on the distal half. Male, valve about half as long as 

 wide, obtusely angled apically; plates broad basally, nearly four times 

 the length of the valve, the submarginally spined margins narrowing to 

 the long acute tips which greatly exceed the short pygofers. 



Distribution: This species has been taken in Riley, Potta- 

 watomie, and Gove counties. 

 Hosts: Unknown.

Form: Medium-sized, fairly robust, posteriorly narrowed. Length, 

 5 to 6.5 mm. Head as wide as pronotum; vertex distinctly produced 

 medially, nearly one-half longer on middle than next the eye, disc de- 

 pressed posteriorly, apex distinctly obtusely angular, margin subacute. 

 Pronotum twice as long as vertex, anterior margin strongly convex, pos- 

 terior margin slightly emarginate, humeral margins slightly longer than 

 the lateral, disc distinctly wrinkled. Elytra moderately long, strongly 

 overlapping and flaring apically. 



Color: Vertex, pronotum, and scutellum dirty-yellowish, elytra milky- 

 white. Vertex irrorate with light brown, apex light with a black spot 

 either side, and usually two dark spots on posterior margin. Pronotum 

 irrorate with light brown, disc darker. Scutellum irrorate with light 

 brown, two dark spots on each margin, between which and apically there 

 is a light spot. Elytra with an indistinct oblique light band before the 

 middle where the dark brown irrorations are not as heavy as on the other 

 portions which are tinged with fulvous. Face yellowish, irrorate with 

 brown, darker above. 



External genitalia: Female, last ventral segment twice as long as pre- 

 ceding, lateral angles rounded, with a broad median incision, widening 

 basally, nearly or quite reaching the base, leaving two large lateral lobes,
