is long and slender and strongly curved and when viewed caudally is 

 widest at the base, then narrowed till near the broadened and distinctly 

 bifid apex. The ventral piece is strongly U-shaped, the arms stout, 

 slightly notched apically, and connected with membranous tissue till 

 near their apices. The last ventral segment of the male is over one-half 

 longer than wide, lateral margins nearly straight, the posterior margin 

 distinctly but not deeply emarginate. The pygofers of the female have 

 a strong median process. The last ventral segment is broadly notched 

 posteriorly nearly one-third the distance to the base. Each of the lateral 

 pieces of the ovipositor bears about fourteen teeth or ridges, at least in 

 the specimen examined, of which the basal ones are small and far apart, 

 the median four or five being quite large, and the terminal four small and 

 crowded. 



Distribution: The specimens at hand were taken in the west- 

 ern part of the state in Morton, Hamilton, Logan and Finney 

 counties. In the collection of the Kansas State Agricultural 

 College are specimens from Logan and Riley counties. Outside 

 of Kansas this species is reported to occur in Colorado, Utah 

 and Arizona. The following map shows its distribution in 

 Kansas as far as is now known : 



Remarks: Of the large number of specimens at hand four 

 are paratypes.
