Ri-r, and between the latter and M, are not at all, or only slightly, in- 

 fuscated. The basal areoles of the fore wings are green; the flaps of 

 both wings are greenish-yellow. Beneath, the entire surface is brownish 

 or testaceous and fresh specimens are pruinose, with the exception of 

 the median portion of the abdomen in rubbed specimens. Legs of the same 

 color as the under side, slightly darkening apically, and showing dis- 

 tinct ridges on the femora. 



For))} : The following are the measurements in millimeters of the speci- 

 mens at hand : 



Length of body 36 to 39 



Width of head 17 to 17.25 



Expanse of fore wings 107 to 112 



Greatest width of foi-e wing 17 to 18 



Greatest width of operculum 7.5 to 8 



Greatest length of operculum 8.5 to 9 



The costal margin of the fore wings is distinctly bent near its middle. 

 The opercula are only slightly longer than broad, overlap slightly for 

 a short distance medially, and the posterior margins are bi'cadly and 

 evenly rounded. 



Ge)iitaUa: The supra-anal plate of the male is roundingly and deeply 

 concave between the lateral angles, and there are no signs of a median 

 tooth. The uncus, viewed laterally, is stout and curving, and tapers to 

 a rather obtuse apex. Viewed caudally it is triangulal-, the apex dis- 

 tinctly pointed but obtuse, and with the usual triangular depression on 

 the upper portion of its dorsal aspect. The ventral piece is strongly 

 V-shaped, the arms being quite stout. The last ventral segment of the 

 male is nearly twice as broad as long, the sides slightly sinuate and 

 the apex very broadly rounded or nearly truncate. The pygofers of the 

 female have distinct but rounded lateral angles and a rather long, slender 

 and acute median tooth. The last ventral segment of the female has 

 the margins straight and the posterior margin is broadly and roundingly 

 emarginate almost one-half the distance to the base. Each lateral piece 

 of the ovipositor has about twelve teeth or ridges of which the median 

 six teeth are quite distinct. 



Distribution: This species has been taken in six counties in 

 the state as shown by the following map. The localities here 

 given would indicate its distribution at least over the eastern 

 two-thirds of the state. The records from Riley, Russell, and 

 Ellis counties are those of the Kansas State Agricultural Col- 

 lege. Van Duzee records its occurrence in Florida, Ohio, Ken- 

 tucky and Texas, as well as in Kansas. Davis says it is a cen- 

 tral United States species.
