Vertex twice wider than long, slightly longer on middle than at eye, 

 margin roiJnding, tip slightly produced, front tvyice wider at ocelli than 

 on clypeus, base of suture rounding; clypeus broadest at the tip; pronotum 

 oae-half longer than vertex, slightly concave behind lateral margins, short, 

 rounding; elytra as in lusoria, central anteapical cell constricted. 



Color: Fulvous maculate with dark chestnut, vertex light fulvous, ocelli 

 white, connected by a light lioe which runs forward on the tip; a round 

 spot on either side at the base of vertex and a median line, extending for-

 the anterior margin maculate with chestnut and bright yellow; scutellum 

 fulvous with a quadrate light-yellow area on disk containing two round 

 chestnut spots; elytral nervures light, chestnut-margined. 



Genitalia: Ultimate ventral segment of female twice wider than long, 

 posterior margin slightly notched, much depressed in the middle, giving it 

 the appearance of being angularly excavated; pygofers very narrow, long, 

 strongly spined; male valve broad, about equaling the ultimate segment in 

 length; plates broad at base, convexly rounding, with stout spines to the 

 nearly parallel margined attenuate, unarmed tips. 



Described from, two males and three females. Collected at 

 Ames, Iowa. One specimen received from Douglass county, 

 Kan. (Kellogg). 



[Note — Since writing this as the description of a new species, an 

 examination of the Gillette and Baker type has enabled us to refer our 

 specimens to their species. As their description was from male alone, we 

 have thought best to allow our description, which covers both sexes, to 

 siand as sent to printer.]
