Female: Length 4 mm., width 1.05 mm.; very similar to the 

 male in form and coloration. 



Some of the Minnesota specimens have the membrane shortened 

 to little longer than the cuneus. 



This form differs from the description of vestitus Uhler in hav- 

 ing antennal segment ii pale, and black only at apex and base, in 

 the paler scutellum with only median line dark, and if the original 

 description is correct, in the much longer antennal segment ii 

 which in discrepans greatly exceeds length of pronotum. 



Food plant: Aster sp. 



Minnesota, New Hampshire, New York. 



Holotype: Male, 7 July, 1917, Cranberry Lake, N. Y. (C. J. Drake);
