NO. 1488. BUTTERFLIES OF BRITISH AMERICA— CARY. 443 



Doctor Fletcher informs me that the Canadian government collection 

 also contains specimens from the vicinity of Dunvegan, Peace River, 

 Athabaska, collected by J. M. Macouii in the summer of 1903. 



POLYGONIA COMMA (Harris). 



In the Fort Simpson collection which Edwards received from Mrs. 

 Ross were several butterflies which he formerly referred to comma.,'^ 

 but later to the winter form h.<irrl><)i (=syn. comm.a)J' As there were 

 no specimens representing the summer form dryas^ Edwards concluded 

 that the species is single-brooded in that latitude. 



1 can tind no other records of occurrence. 



POLYGONIA ZEPHYRUS (Edwards). 



This western Poli/gonia is included in the present list solely on the 

 strength of Edwards' Fort Simpson reference." No further data are 

 given, but the specimen is supposed to have been received by Edwards 

 from Mrs. Ross. Fort Simpson is far north of the normal range of 

 P. zephyr ux^ and recent collections from Mackenzie River localities 

 have not contained it. 



POLYGONIA FAUNUS (Edwards). 



This butterfly seems to have a general distribution in Athabaska and 

 southern Mackenzie. I noted it in 1903, as follows: Pierre au Calu- 

 met/^ May 29, one; Smith Landing, June 12, two; Fort Resolution, 

 June 23, two; delta of the Athabaska River, August 5, two; Pelican 

 Rapid, Athabaska River, August 25, one. A single specimen was 

 collected at Smith Landing, June 12. Mr. Preble collected another 

 example at Fort Simpson, May 24, 1904. 



Edwards records this species from Fort Simpson;' while Scudder 

 mentions specimens from "Great Slave Lake,'' which are in the 

 Museum of Comparative Zoology in Caml^ridge.-^ 



POLYGONIA GRACILIS (Grote and Robinson). 



I collected a specimen of this species at Fort Providence, Jul}^ 3, 

 1903. It was taken at the flowers of the silvei'berry {EIxagnu>< argen- 

 ted). Mr. Preble secured three specimens in 1904, one at each of the 

 following localities: Fort Simpson, April 24; Fort Good Hope, June 

 22; Fort McPherson, July 8.
