what fine haired, truncate tips bearing membranous tails which are much 

 shorter than in auronitevs, lateral margins spined; pygofers long and 

 narrow, much exceeding plates, spiny on posterior half. 



Distribution: This species though not yet taken in the state, 

 should occur in the eastern portion. 

 Hosts: De Long reports it on oak.

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

 anteriorly. Pronotum with anterior margin very convex, posterior mar- 

 gin slightly concave. Elytra 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 basal portion. 

 Pronotum having mottled appearance. Scutellum frequently appearing 

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

 on claval suture, nervures 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 to 

 tips of pygofers. 



Distrihution : Taken in Douglas and Pottawatomie counties. 



Hosts: Osborn records a single specimen from Maine "on 

 blueberry." It of course has some other host in Kansas.

Form: Larger than preceding species. Length, 5.5 to 6 mm. Vertex 

 nearly as long as wide, disc flat, apex acutely pointed. Pronotum more
