vertex smooth and polished; frons smooth, polished, with a small, 

 shallow pit below anterior ocellus, and with a low median longitudinal 

 elevation; face about 2.50 times as wide as long, smooth, and with a 

 median tubercle above ; clypeus with longer pubescence than the face, 

 median basal part convex, apical margin not notched ; temple slightly 

 wider than eye ; galea short. Middle portion of lateral face of prono- 

 tum weakly ruguloso-punctate ; median lobe of mesoscutum with a 

 depression each side of the median line; notaulices finely foveolate; 

 upper groove of mesopleuron wide, shallow, distinctly partitioned, 

 lower groove weakly, finely foveolate ; and posterior groove coarsely 

 foveate; metapleuron ruguloso-punctate, triangular anterior portion 

 plain, a deep pit on the margin between the anterior and posterior 

 portions, and a deep, coarsely foveate groove along upper margin of 

 posterior face; j^ropodeum finely rugose, carinae delimiting areola 

 low, costulae not defined, spiracle short ovate. First abscissae of 

 radius and basal vein about equal; third abscissa of cubitus longer 

 than fourth ; first intercubitus sharply angulate and with a short stump 

 of a vein from the angle; second abscissa of cubitus 1.50 times as long 

 as recurrent vein ; nervulus postf ureal by 0.67 its length ; interanal vein 

 absent. Second and fifth segments of fore tarsus about equal ; hind 

 tibia slightly curved, widened at apex, but not expanded into a strongly 

 flaring process ; the inner spur of middle tibia slightly more than half 

 as long as basitarsus, second and fifth tarsal segments about equal; 

 inner spur of hind tibia about half as long as basitarsus, basitarsus 

 about as long as the last four tarsal segments combined, second tarsal 

 segment longer than fifth ; hind tarsal claws pectinate, each with four 

 visible teeth basally. First abdominal suture slightly curved to the 

 margin ; second and third tergites of equal length medially ; hypopyg- 

 ium about as long as third and fourth abdominal tergites combined, 

 its median ventral line without a longitudinal fold ; ovipositor sheath 

 short, the exposed part about 0.25 as long as the hypopygium, smooth 

 and polished (pi. 5, fig. 21). 



Type.—U.S.'NM. No. 58295. 



Type locality. — Clarksville, Tenn. 



Described from a single female reared August 1909 "from bud- 

 worm." Presumably the host was the tobacco budworm, Heliothis 

 virescens (Fabricius). 



Very similar to nigriceps Viereck, the common parasite of Helio- 

 this virescens^ but it may be distinguished from that species by the 

 much less strongly sculptured metapleura and propodeum and by the 

 relatively long second tergite.
