distinct." In his letter to Mr. Gregson, Dr. Fletcher adds: "If 

 about forty of our American species are valid, this also, I think, 

 is a valid species. I have specimens of it from the Rocky 

 Mountains right across the plains to the borders of Ontario." I 

 have reason to believe that he refers to the species which he 

 named cypris for me a few years ago. 



5. A. /ais, Edw. Very common. June to August. Also at Banff in 



Aug. (Sanson). Lacombe "uplands, July, common" (Gregson). 



6. A. electa, Edw. Not common. July and Aug.; also at Banff (Sanson). 



Lacombe " uplands, not common " (Gregson). One $ and one 

 2 out of five o* 6 an d tvvo 9 $ in my series have been labeled 

 electa by Mr. W. H. Edwards. Here I suffer sadly from lack of 

 material, as, though the form is far less common than /ais, I 

 could long ago have obtained a good series, had it not been for 

 pressure of other business during its season. I have atlantis 3 

 from Prince Edward Island, which I cannot distinguish on the 

 upper side from Calgary electa, though on under side of 

 secondaries the spots are slightly larger, the buff submarginal 

 band distinctly narrower, and ferruginous area more rusty reddish 

 than in most of my short series. A <$ , sent me from Banff by 

 Mr. Sanson, and named electa for him by Dr. Fletcher, is almost 

 an exact counterpart of my P. E. I. at/antis, though smaller than 

 it or any of my electa ; whilst atlantis $ , also named by Dr. 

 Fletcher, from Mr. Gregson, of Lacombe, differs from a Calgary 

 $ , labeled electa by Mr. Edwards, only in being slightly larger. 

 A worn $ which I look at Laggan last August, seems to come 

 nearer the P. E. I. specimen than does anything I have taken 

 near Calgary. The species, whatever it is, is slightly darker than 

 /ais, the markings altogether heavier, and dusky brown basal area 

 above darker and wider in extent. The veins above on primaries 

 are also much more broadly clothed with black scales than in 

 /ais. On the under side the differences are less pronounced, 

 though the ferruginous area on secondaries is usually, though not 

 always, paler in /ais than in the other form. The above remarks 

 apply to the <$ £ . I have only seven o. ? belonging to either 

 form, and must confess my difficulty in deciding where to place 

 them. Atlantis, which is recorded by Geddes from the Rocky
