very similar to the figure of the cerci of the next species (fig. 43). 

 The cerci of the female are simple, pointed, about three times as long 

 as the basal width. Ovipositor short and heavy, usually but little 

 more than one-half as long as the posterior femora, but sometimes 

 three-fourths as long and curved upward. 



General color brownish, sometimes yellowish brown; tip of the 

 ovipositor, knees of the posterior femora and edge of the postei'ior 

 margin of the pronotum blackish and the lower and posteiior margins 

 of the pronotum usually, but not always, yellowish, much lighter than 

 the general color. 



Measurements. — Length, pronotum, male, 7-8 mm., female, 7.5-8; 

 posterior femora, male, 21-24, female, 24-25; cerci, male, about 1.5; 

 ovipositor, 13-18. 



Type—Q2X. No. 10169, U. S. National Museum. 



Material examined. — Five males, five females, Texas, Types, U. S. 

 National Museum, and specimens from the same State in the collections 

 of Scudder and Morse, 



Described from two males and five females from Texas (Belfrage). 



The Scudder collection contains one pair from the same collection, 

 and Professor Morse took a female at Quanah, Texas, on August 21. 

 This specimen has the ovipositor, 18 mm. long, 4 mm. more than the 

 othei- females studied. Otherwise it is normal. 



The longer posterior femora with the more distinct ventral spines 

 and the usually shorter ovipositor will serve to separate this species 

 with considerable certainty from its nearer allies.
