Canadian records 



Ontario: Ottawa, 2 $ 9 (lO-VI-1909, A. Gibson) ; Merivale (2-VII-1935, T. N. 

 Freeman). 



Quebec: Meach Lake {13-VI-1906, July 1906, 30-VI-1937, C. H. Young) ; Wake- 

 field (13-VII-1925, F. P. Ide). 



Remarks. — I have not seen the specimens, nor do I know the sexes 

 of the specimens from Merivale, Meach Lake, and Wakefield, but the 

 identification is presumably correct.
