A specimen from "Great Slav^e Lake" in the "Cambridge Museum" 

 (Museum of Comparative Zoology) is mentioned by Scudder." Strockor 

 records a specimen from the "Athabaska region," obtained from 

 Geffcken.* Francis A. Heron informs me tliat there is a specimen 

 in the British Museum, collected at Great Slave Lake in July, 1894, 

 by W. G. Cumming-. 



Although apparently of general distribution in the North, J*, (/ra- 

 cilis is nowhere common. 



POLYGONIA PROGNE (Cramer). 



This species was not taken by us in 1903-4. White records speci- 

 mens taken by Richardson at Fort Simpson, and also on the "Arctic 

 Coast between 67^"^ and 68'^," in 1848/' Scudder^' expresses doubt as 

 to the Arctic coast specimens being progne^ but makes no comment 

 on the Fort Simpson record. 



In more recent years Doctor Fletcher has recorded j'^^'oj/we? from 

 Fort Simpson, where Frederick Bell collected two examples, July 12, 

 1888.'' It has also been taken at FortMcLeod, British Columbia, and 

 on Belly Riv^er, Alberta (Capt. Gamble Geddes). 



EUGONIA J-ALBUM (Boisduval). 



Two of these butterflies were seen on the Athabaska River, some 60 

 miles above the delta, August 6, 1903. A pile of freshly-cut spruce 

 wood lying on the steamer apparently attracted the insects, as they flew 

 about the deck as long as the boat was moored to the river bank. Both 

 butterflies were in good condition, but eluded capture. 



Scudder has the following note in regard to E. j-album : "Specimens 

 labeled 'Arctic America, Ross,' may be seen in the British Museum, 

 probably collected in the vicinity of Great Slave Lake."-^ I can And 

 no further records for the Athaliaska-Mackenzie region, but the species 

 has been taken at various localities in the southern provinces. Appar- 

 ently its range is restricted to the Canadian fauna. 



EUVANESSA ANTIOPA (Linnaeus). 



The Mourning Cloak butterfly occurs commonly throughout the 

 region as far north as Fort McPherson (latitude 67° 20'). I first 

 observed it on Jul}^ 4, 1903, at Fort Providence, where numbers were 

 flying about the 3'oung growth of aspen {Populus tremnloides). On my
