One male, two females, Wauseon, Ohio, collected 

 by Professor Jas. S. Hine; the male is dated Aug. 

 25, 1902, the females Sept. 4 of the same year; one fe- 

 male, Aberdeen, S. D., Aug. 12, 1916 ( W. E. Dove) . 

 It seems practically certain that these males and fe- 

 males belong together; nevertheless I have taken the 

 precaution to place the type label on one of the fe- 

 males, as the specific name refers to the larvipositor.
