144 THOMAS SAY FOUXDATIOX 



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

 .29, 303) ; in most of the specimens the frontal stripe 

 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, 

 sometimes distinctly blackened, ending in an almost 

 square tip. 



Length 61/0-9 mm. 



Twenty-six males, fifteen females: eight males 

 and twelve females are from Wellington, Kan., bred 

 from grasshoppers by E. G. Kelly (Webster Xo. 

 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 Melanoplus 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 

 CM. Packard (Pasadena, No. 16163) ; two from 

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

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

 one Pullman, Wash. (Doane). 



Altliough 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 w^hich appear to be tlie 

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

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

 attacked flying grasshoppers { Schist occrea ameri- 

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

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

 10895.
