forward and rather blunt; the outer forceps a little shorter and 

 wider, the front edge slightly concave and the tip a little more acute. 

 Legs black; tibiae brown, middle tibia with two or three bristles 

 on the outer front side; hind tibia with a row of cilia mixed with 

 several larger bristles. Claws and pulvilli large, the latter grayish. 

 Wing subhyaline with slight brownish tinge along the veins, bend 

 of fourth vein almost rectangular but a little rounded, last section 

 slightly concave; third vein wnth only two or three hairs at base. 



Female. — Vertex 0.29 of the head width, the pollen gray to the 

 second reclinate bristle, changing as in the male to a very deep golden 

 color, almost orange; the two orbital bristles are rather far apart 

 and the parafrontals have fewer and smaller hairs than usual. There 

 is a changeable dark spot in the pollen at the level of the lowest 

 frontals. Abdomen rather more uniformly pollinose than in the 

 male, still with slight tessellation. Middle tibia with one large, and 

 above it one small bristle on outer front side. Wing hyaline. 



Length, male, 9.3 mm. ; female, 8.8 mm. 



Described from one male and two females ; the former was collected 

 at Tucuman, Argentina, by E. W. Rust, on March 16, 1917, while he 

 was connected with the agricultural experiment station; it bears the 

 label " Est. Exp. A. C. No. 233." The females, one of which is the 

 allotype, were reared at the same place in February, 1929, by Harold 

 E. Box, from cutworms, Reviigia repanda; both of these have the 

 puparia with them, and one is returned to Mr. Box. 



Type and allotype. — Male and female, Cat. No. 41896, U.S.N.M. 



The species agree with the characters of the subgenus Neopales 

 Coquillett.
