second; interanal vein absent or represented by a pigmented line. 

 Second and fifth segments of fore tarsus about equal, apex of hind 

 tibia not thickened or expanded into a flaring process ; inner spur of 

 middle tibia about as long as basitarsus, second and fifth tarsal seg- 

 ments about equal; inner spur of hind tibia about half as long as basi- 

 tarsus, basitarsus shorter than remaining tarsal segments combined, 

 second tarsal segment longer than fifth. First abdominal suture ex- 

 tending obliquely forward to the margin ; second tergite shorter than 

 third ; hypopygium pointed in profile, and about as long as first two 

 abdominal tergites combined ; its median ventral line without a longi- 

 tudinal fold ; ovipositor sheath pubescent, its exposed part slightly less 

 than the first three tergites combined (pi. 5, fig. 27) . 



Described from the type. 



Male. — Essentially similar to the female. 



Type. — In the Academy of Natural Sciences of Philadelphia. 



In addition to the type, which is from Illinois, about 25 specimens 

 have been examined. These are from localities in Virginia, Iowa, 

 Tennessee, and Ontario, Canada. 



CARDIOCHILES NEBRASCENSIS, new species
