shaped, spiracle long ovate. First abscissae of radius and basal vein 

 about equal; third abscissa of cubitus much shorter than fourth; 

 recurrent vein and second abscissa of cubitus about equal; nervulus 

 postf ureal by about 0.67 its own length; first and second abscissae 

 of submedius about equal ; interanal vein represented by a light pig- 

 mented line. Fifth segment of fore tarsus thicker and longer than 

 second, hind tibia flattened and broadened toward apex, but not ex- 

 panded on outer apical margin; inner spur of middle tibia slightly 

 shorter than basitarsus, second tarsal segment shorter than fifth; 

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

 flattened and broadened, and longer than the last four tarsal seg- 

 ments combined; hind tarsal claws pectinate basally. First ab- 

 dominal suture extending obliquely forward to the margin; second 

 tergite about half as long as third ; liypopygium in profile pointed, 

 about as long as the first two tergites combined, its median ventral 

 line folded ; ovipositjor sheath about as long as hind basitarsus, pubes- 

 cent, broadened to near apex, its greatest width about equal to length 

 of second segment of hind tarsus, the tip bent ventrally (pi. 5, fig. 19). 



Male. — Essentially similar to the female. 



Type. — Lost. 



The material studied includes specimens from Pennsylvania, Mary- 

 land, Virginia, District of Columbia, Kentucky, Georgia, and Kansas.
