Female. Front .29 of the head (three gave .29,

 is pollinose above, blending with the paraf rontais ; 

 orbitals and outer verticals present; paraf acials 

 quite wide, with a double row of hairs below; genital 

 segment red, the last sternite moderately elongated,

Twenty-six males, fifteen females: eight males 

 and twelve females are from Wellington, Kan., bred 

 from grasshopi^ers by E. G. Kelly (Webster No. 

 7398) ; three additional males differ only in having 

 other Webster numbers (7399, 8281); two males 

 Sacramento Co., Cal., Sept., "bred from C spretus" 

 (C. V. Riley collection in National Museum) ; three 

 pairs bred from Mdanoplus atlanis at Brawley, 

 Cal., by T. D. Urbahns (his No. 1654) ; three males 

 Natrona, Cal., July 15 and 18, 1885, bred material 

 but unaccompanied with data (same collection) ; a 

 pair from Alpine, Cal., reared from a grasshopper by 

 C. M. Packard (Pasadena, No. 16163) ; two from 

 London, Ont. (Hough coll.) ; two from Lewis- 

 ton, and one from Moscow, Idaho (author's coll.) ; 

 one Pullman, Wash. (Doane). 



Although none of the females were taken in 

 copula, there is no reason to question the identity of 

 these from Wellington; I have a large number of fe- 

 males from the other localities wliich appear to be the 

 same, among them five collected at Trenton, Ky., 

 Sept. 2, 1915, by Geo. G. Ainslie, wlio noted that they 

 attacked flying grasshoppers {Schistoccrea ameri- 

 cana) in the manner recorded by E. G. Kelly for S. 

 Kelly i (Jour. Agr. Research ii, 435), Webster No. 

 10895.
