jMass. (H. H. Newcomb) ; Durham. N. H.* ; Norway, Me.*; Orono, ^vle. 

 (M. E. Fernald, in coll. Cornell University) ; and Digby, Nova Scoiia 

 (John Russell). From its occurrence at Medford and Milton, the 

 Massachusetts localities (Needham and Walpole), given by Scudder in the 

 Butterflies of the Eastern U. S. and Canada, for the varietal form of inis 

 having " the outer margin of the primaries .... narrowly hoary," 

 may be safely included as referring to this species. 



In the Butterflies of Maine, C. H. Fernald says : " This is a common 

 species in Maine," and Fiske speaks of it as abundant in certain parts of 

 New Hampshire. 



Fo/ios was taken in 1907 by Mr. Charles A. Hill, of Chicago, at 

 Pine, Ind., in the sand-dune region along the southern shore of Lake 

 Michigan, where Synchloe olympia was recently unearthed. Mr. Hill took 

 fourteen specimens, and reports the species fairly abundant in that locality. 



In the west polios has been taken at the " head of Pine Creek, 

 Calgary, Alberta (F. H. W'olley Dod)" ; forty nnles south of Athabasca 

 Landing, Athabasca^ (McCary) ; Waghorn, Alberta (P. \\. Gregson, in the 

 collections of John C!omstock, Evanstoii, 111., and Alexander Kwiat, 

 Chicago, 111.). Dr. Henry Skinner^ gi\es ae; another Canadian locality, 

 Olds, Alberta. Also in Colorado (Morrison, in collection of O. Meske, 

 and David Bruce, in collection of Cornell University) ; Graham's Park on 

 Rio de los Pinos, Colo.*''; .South Park, Colo.*; and Chimney Gulch, near 

 Golden, Colo. (Dyar and Caudell). 



Without much hesitation I include Puget Sound (Wright), the locality 

 given for the specimen figured in Butterflies of the West Coast (I.e.). 



Time 0/ F/ig/it. — Species single-brooded, the butterflies appearing (in 

 New Jersey) with augiistiis about the middle of April, ordinarily becoming 

 abundant before the last of the month, and rarely enduring through May 

 (Watson). In New Hampshire "earlier in its emergence ' than any of the 

 allied species ; . . . . taken on willow blossoms in Durham as early 

 as April iQlh" (Fiske). ^" In Maine it " is on the wing during the middle

7. So reads the label, though the only Athabasca Landing which I have found 

 on the map is in Alberta.

9. Misprinted " Cal." in the original description oi polios. 



10. Probably careful field work will show that augustiis is on the wing almost 

 or quite as early.
