SASKATCHEWAN.— Prince Albert, June 18, 1905, i 9. Also 

 I 6 i 3 ? s from Saskatchewan without farther data (Wg). 



To Mr. Kenneth J. Morton is due the credit of first recognizing 

 the close relationship between this species and C. lufitilaium. 



Can this be the Agrio7i interrogatuin Selys, described from the 

 feriiale only, from Saskatchewan? (Bull. Acad. Belg. (2) 41, p. 

 1254, 1876).

I am unable to distinguish the females of this species from the 

 following, and therefore have not included them in the above list 

 Females probably of both species have been received from the fol- 

 lowing localities : Aweme, Man., July i, 1909, i 9 (C). Winni- 

 peg Beach, Man., June 19, 1909,5 9 s (Ws). Abernethy, Sask., 

 June 27, 1903, I 9 (Wg). Duck Lake, July 22, 1967, 18 9 s (Wg,

 i-;o8, 29s (S). Near Waterton Lake, Aug. 5, 1908, i 9 (Cowdry). 



This circumpolar species doubtless occurs also in Manitoba, as I 

 have taken :t in Northwestern Ontario (Nipigon).

The females, as stated above, are listed with the preceding 

 species, from which they are apparently inseparable.
