126 THE UNIVERSITY SCIENCE BULLETIN. 



Form: Length, 4.5 to 5.75 mm. Vertex wider than long, not as 

 pointed apically as in sanctus. Pronotum about twice as wide as long, 

 quite convex anteriorly, slightly concave posteriorly, lateral margins 

 long, about the length of the humeral margins; elytra long, nodal vein 

 arising from the discal cell, postnodal cell scarcely widened distally. 



Color: Vertex yellowish -white with very characteristic broad orange 

 band across middle in front of which is a short black band, and also a 

 larger one parallel with the anterior margin. Pronotum with orange 

 band on anterior margin and a fainter one on the posterior half, parallel 

 to the posterior m.argin. Scutellum with the basal angles dull orange, 

 the disc darkened medially. Elytra brownish, nervures darker, three 

 spots on clavus along median suture, black. 



External genitalia: Female, last ventral segment nearly four times 

 as long as preceding one, cleft by broad excision, reaching nearly to the 

 base, into two large rounding lateral lobes; the spiny pygofers are long 

 and narrow, exceeded slightly by the ovipositor. Male, valve broad and 

 short, truncate posteriorly, or with very small median tooth; plates large 

 and broad, obtuse apically and with an impressed line parallel to the 

 lateral margin which is covered with long silky hairs; long, membranous 

 and hairy tail-like structures terminate the plates; spiny pygofers long 

 and narrow, much exceeding plates. 



Distribution: Taken in Douglas, Pottawatomie and Riley 

 counties. 



Hosts: Professor Osborn gives Geranium Robertianum as 

 a host. De Long reports taking it on canebrake.

Form: Larger than preceding species. Length, 5 to 6 mm. Vertex 

 wider than long, flat, with transverse impressed line, roundingly angled 

 anteriorly. Pronotum twice as broad as long, lateral margins long, an- 

 teriorly convex, posteriorly slightly concave. Elytra long and somewhat 

 flaring posteriorly, nodal vein arising from discal cell, postnodal cell 

 scarcely widened posteriorly. 



Color: Orange-yellow marked with white. Vertex with median line, 

 six spots near anterior margin of pronotum, two spots on sides, apex and 

 two lines on disc of scutellum and several spots on elytra, white. 



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

 as preceding one, posterior margin rounded and medially produced; 

 pygofers long and narrow, slightly exceeded by ovipositor, spiny on pos- 

 terior half. Male, valve triangular, narrow but long; plates long, some-
