appeared to be quite fresh. Mr. Sanson's records for Banff are 

 May 29th and June 18th. 



20. M. Whitneyii, Behr. ? A single $ , in fine condition, taken by Mr. 



Hudson in the spruce near Billings's lumber mill, on July 5th, 

 1896, is probably either this species or palla, Bd., which is 

 recorded from the Crow's Nest Pass by Geddes. 



21. Phyciodes ismeria, Bd.-Lec. Common at Lacombe ; June (Gregson). 



22. P. tharos, Dru. Common everywhere. June to September. 



23 P. pratetisis, Behr. Common on the hill-prairie near Calgary, June 



to August ; Banff (Sanson). 

 23a. [Phyeiodes sp ? A single $ near Lineham's lower log camp, 



July 13th, 1896, which I have been unable to identify. It may 



bean aberrant pratensis.] 



24. Grapta satyrus, Fdw. Fairly common ; Cal- 



gary and Banff. 



25. G. /annus, FAw. Not common; Calgary and 



Banff. 



26. G. zephyrus, Edw., vel. progne, Cram. Com- 



mon, apparently everywhere. 

 Here I must confess myself somewhat at sea in the matter of 

 species, though I have made a careful study of all the scanty 

 material I could obtain, including specimens kindly lent me for 

 the purpose by Mr. Gregson and Mr. Sanson. A specimen sent 

 me from Banff as satyrus, on the authority of Dr. Fletcher, 

 resembles a Calgary specimen labeled " Like satyrus in Elwes's 

 collection"; and zephyrus, named for me by Dr. Holland, agrees 

 with zephyrus named by Dr. Fletcher from Banff, and with a 

 Calgary specimen labeled " Like zephyrus in Elwes's collection." 

 Progne is the name given to a Calgary specimen of the same form 

 by Mr. W. H. Edwards, and to a similar Lacombe specimen by 

 Dr. Skinner. Mr. Bean used to take a species at Laggan which 

 he called zephyrus, and I have placed the form under that name. 

 Satyrus differs from this form in having larger black spots, darker 

 basal area above, and usually, though not constantly, larger 

 submarginal yellowish blotches. Beneath, both forms are very 

 variable, both in colour and shape of band and strigations, and 

 in the shape of the white discal spot. The colour in zephyrus is
