1108 THE BUTTERFLIES OF XEW ENGLAND. 



It is a littlo larger tlian E. pliilodice, the black points are a tritle larger tlian there, 

 and Mr. Fletcher thiiik.s the ground color more yellowish than in E. philodice, but of 

 this I am not so confident; the wine-glass shaped appendages below the uppermost 

 series have the cup longer than broad, while in philodice it is of equal length and 

 breadth. 



Geographical distribution (25: 6). This butterfly is a member of 

 the Hudsonian fauna and apparently is most at home along the porthern 

 shores of Lake Superior, from whence it was first brought thirty years ago 

 by Professor Agassiz. It has rarely been found south of tlie Dominion of 

 Canada, but extends along a tolerably wide belt of country from the Rocky 

 Mountains to the Atlantic. If Hagen is right in assigning to this species 

 several forms which have been described under other names, then its range 

 is much wider than here indicated. But as it is not in my power to make 

 the necessary comparisons at the present time, I prefer to follow here 

 the guide of Edwards, who has proved to be nearer correct in his judg- 

 ment of affinities among the species of Eurymus than has Hagen, in several 

 instances where breeding experiments have settled matters previously in 

 doubt. This butterfly, then, has been found at least as far as the Rocky 

 Mountains, and in the extreme west has been taken by Geddes at Stephen, 

 the highest point of the Rocky ^Mountains traversed by the Canadian and 

 Pacific Railroad, by Tyrrell at Miry Creek, lat. 54° 4', long. 112° 10', at 

 the mouth of the Saskatchewan (Scudder), and at Moose* on James's Bay 

 (Edwards) ; along the northern shore of Lake Superior it swarms to a 

 point at least as far south as Sudbury, north of Georgian Bay, where 

 it is abundant (Fletcher, Scudder) ; east of this it has never been taken 

 in any great numbers, but is recorded along the north coast of Labrador 

 from Sawbill River to Natashquaun (Couper), the Mingan Islands, 

 Anticosti (Couper), Godbout River "rare" (Corneau), Cape Breton 

 (Thaxter) and Newfoundland (Edwards), the latter point being brought 

 to my notice after the preparation of tlie map. It is reported from 

 Buckingham near Ottawa (Whyte) ; Mr. Caulfield has also found it on 

 Montreal Mountain, it lias been taken at Quebec, and Mr. Mann procured 

 one specimen at Owl's Head, Lake Memphremagog, just north of our 

 border. 



In New England it has only been taken on two occasions, once by 

 Professor Hamlin at Water ville. Me., and once by myself at Franconia 

 Notch, N. H. ; but it seems highly probable that in the northern part of 

 New England it will be found not very uncommonly if sought for at the 

 proper time. It has probably been heretofore confounded with the rominon 

 philodice. 



Haunts. Mr. Couper, speaking of this butterfly as it occurs on tiie 

 Labrador coast, says : "It is not frequently seen near the sea ; but generally 



• Ferhaps this was one of the forni.s from Moose identified by Wier under other names.
