Form : Small and stout. Length, 5.5 mm. Head slightly wider than 

 pronotum; vertex one-third longer on middle than next the eye, three 

 times as wide as long", obtusely angled apically. Pronotum twice as wide 

 as long, basal half transversely wrinkled, lateral margins short, humeral 

 margins longer, posterior margin slightly emarginate. Elytra short, 

 flaring, claval veins slightly approaching each other near the middle. 



Color: Dark fulvous; vertex, pronotum and scutellum soiled yellowish- 

 white, usually nearly uniformly irrorate with dark brown, posterior 

 two-thirds of pronotum often darker. Elytra whitish, heavily inscribed 

 with dark brown, leaving spots here and there. Face yellowish-white, 

 nearly uniformly irrorate with dark brown. 



External genitalia: Female, last ventral segment over twice longer 

 than preceding, narrowed posteriorly, posterior margin broadly emargi- 

 nate nearly one-third of distance to the base, emargination with a deep 

 median slit, lateral angles lobular and appressed to the pygofers; py- 

 gofers semirobust, exceeded by the ovipositor, very sparsely spined. Male, 

 last ventral segment as long as preceding; valve broad, triangular, 

 slightly longer than ultimate segment, margins indented just before the 

 acutely pointed apex; plates broad, ventrally convex, submarginally 

 spined margins narrowing to obtuse tips which exceed the pygofers. 



Distribution: Taken in Pottawatomie, Riley, Gray and
