Form : Length, 5 to 5.5 mm. Vertex as long as wide, quite angulate 

 anteriorly. Pronotum with anterior m.argin very convex, posterior mar- 

 gin slightly concave. Elji;ra much exceeding abdomen, nodal vein rising 

 from anteapical cell, postnodal cell scarcely widened distally. 



Color: Grayish-brown. Vertex light, marked with brown lines, 

 median spot near apex, preapical marginal lines and ocelli appearing 

 white, as does the portion between the brown lines on the basai portion. 

 Pronotum having mottled appearance. Scutellum frequently appearing 

 to have six light spots. Elytra with three very characteristic light spots 

 on claval suture, ner\'ures dark. 



External genitalia: Female, last ventral segment three times as long 

 as preceding, lateral angles broadly rounding to nearly truncate, slightly 

 excised posterior margin; pygofers long, widest near middle, spiny on 

 distal half, slightly exceeded by ovipositor Male, valve small, broadly 

 triangular; plates wide and short, slightly haired marginally, about half 

 as long as spiny pygofers and tipped with membranous tails reaching t^.) 

 tips of pygofers. 



Distribution : Taken in Douglas and Pottawatomie counties.
