and cupping to very broad truncate tips, base enclosed by pygofers, 

 which, slightly exceeding tip of plates, form a median keel. 



Male internal genitalia: Styles of same type as in sanguinolenta but 

 without latero-caudal corner drawn out; connective much as in sanguin- 

 olenta and yet differing in several details; cedagus with rather long arm 

 for attachment to connective and two arms forming a very shallow V, the 

 whole forming an irregular V with the base formed by the part attached 

 to the connective. 



Distribution: This species seems to have a state-wide dis- 

 tribution, as shown by the following map : 



Hosts: Definite host plants seem to be unknown. It is gen- 

 erally taken sweeping the prairie grasses.

Form: Smaller than the other species of the Agallia group, broad 

 and flattened. Vertex broad and as long as in any member of this group, 

 distinctly longer at middle than next the eyes. Pronotum more than 

 twice as wide as long, coarsely punctured, anterior margin broadly con- 

 vex, posterior margin slightly concave, humeral margin long, reaching 

 the eyes. Elytra a little longer than the abdomen. 



Color: Generally uniformly light cinereous except for two small 

 black spots on vertex. Much lighter than uhleri, being the lightest 

 colored member of the Agallia group.
