Form: Large and elongate. Length, 5.75 to 7 mm. Vertex short, 

 over twice as broad as long, margins nearly parallel, sloping, and broadly 

 rounding to front. Pronotum twice as long as vertex, lateral margins 

 convex, widening posteriorly, humeral margins straight, distinctly angled 

 with slightly emarginate posterior margin. Scutellum large. Elytra 

 very long and narrow, greatly exceeding the abdomen. 



Color: Rich reddish-brown; vertex yellowish, two large black apical 

 spots between red ocelli, a fulvous transverse band on basal portion. 

 Pronotum fulvous with a broad median band and sometimes a narrow 

 yellow band on posterior margin. Elytra fulvous with lighter nervures 

 and a distinct yellow stripe along costal suture. Yellow beneath. 



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

 as preceding, lateral margins rounding into rounded posterior margin, 

 sometimes with a broad median keel; pygofers rather narrow, slightly 

 exceeded by ovipositor, sparsely bristled. Male, last ventral segment as 

 long as preceding; valve small, triangular, apex obtuse; plates broad on 

 proximal half, then tapering to long attenuate tips; pygofers short, equal- 

 ling or slightly exceeding plates, sparsely bristled. 



Distribution: Taken in Cherokee and Pottawatomie coun- 

 ties. 



Hosts: Doctor Ball gives this as a Cratsegus species. De 

 Long records sweeping specimens from oak.

Form: Smaller and narrower than preceding species. Length, 5 to 6 

 mm. Vertex even less produced than in kennicotti; twice as broad as 

 long, sloping, broadly rounding with front. Pronotum, scutellum and 

 elytra as in kennicotti. 



Color: Lighter, otherwise as in kennicotti. 



External genitalia: Female, last ventral segment nearly as long as 

 broad, lateral margins broadly rounding with somewhat produced pos- 

 terior margin, keeled medially; pygofers rather narrow, slightly exceeded 

 by ovipositor, slightly bristled. Mfele, valve broad and short, obtuse 

 apically; plates broad basally, spiny margins concavely narrowing to 

 long attenuate tips which nearly equal the bristly pygofers.
