between the eyes, which fades out only at hind border of the 

 head. 



9 , last ventral segment produced, angles retreating, pygo- 

 fers long and slender, not reaching the tip of the ovipositor. 

 & , valve broad, short ; plates large, tapering to a sharp point 

 and reaching about three-fourths the length of the pygofers. 



Described from Anglesea, N. J. (Smith), and New York 

 City (Southwick). 



Specimens also referred to this species from Ames, Iowa, 

 (Iowa State College collection), and from Urbana, 111. (Mc- 

 Elfresh). While the types which have been in hand for 

 examination and some of the other specimens seem quite 

 distinct, there are others evidently belonging here, which 

 vary toward immistus. The male plates, however, seem to 

 furnish a good character. One specimen (Baker collection) 

 is labeled " Willow, September 8."
