154 THE CANADIAN ENTOMOLOGIST. 



Stigma; its first abscissa not quite perpendicular and slightly 

 shorter than the cubital crossvein, second abscissa curving very 

 slightly into the radial cell toward the apex and attaining the wing 

 margin far above the extreme wing apex; recurrent nervure in- 

 terstitial with the cubital crossve n; submedial cell longer than the 

 median; second discoidal cell open beneath. 



Posterior legs longer than the whole body, their tibiae scarcely 

 as long as the femora and two joints of the trochanter combined; 

 coxae equal to the first abdominal segment, first tarsal joint twice 

 the length of the second. 



First abdominal segment convex, rugose, wider at apex than 

 at base; bicarinate at base, the carinae orig nating at the lateral 

 angles and converging posteriorly, but fading out before meeting; 

 spiracles not prominent and placed slightly before the middle of 

 the segment; sides of the segment paral el beyond the spiracles; 

 the posterior lateral angles somewhat flattened; whole abdomen 

 slightly longer than the thorax; the segments beyond the first 

 smooth and but little wider than the first segment at apex, their 

 sides parallel. Ovipositor sheath less than one-fourth the length 

 of the abdomen. 



Colour as in the preceding species, except that the legs are 

 reddish testaceous and the abdomen, including the first segment, 

 is brownish testaceous. 



The male is like the female. 



Type locality. — Lafayette, Indiana. 



Host. — Agromyza angidata. 



Type No. 15597, United States National Museum. 



Four specimens received from Prof. F. M. Webster, reared by 

 P. Luginbill, and bearing Webster's number, 9700. 



This species would apparently fall in Foerster's genus Mesora, 

 which genus is believed to be untenable.

Prosopis jnesiUcE Cockerell. 

 This is a valid species, and not a form of P. cressoni as it is 

 given by Metz. Externally the two are easily separable. P.
