This species is described after 4 £ 1 9 taken at the Portage of 

 the Slave River. That the female belongs to the male seems to 

 be assumed merely from the fact that both arrived in the same lot. 

 I have two females from Umatilla, Or., and Yakima, W, T., June 

 25 and July 5, entirely like the figured one. They were collected 

 among numerous C. Edwardsii, and are entirely pale yellow 

 without a border. As similar ones with a faint beginning of a 

 border were taken in copula with C. Edwardsii, there can be no 

 doubt that the females without border belong also to C. Edwardsii. 

 A male from Dease Lake at the same latitude with the Portage 

 of Slave River only a few miles farther west, proves that the 

 sj^ecies goes so far north ; until a sufficient proof is given to the 

 contrary, this female of C. Christina cannot be separated from 

 C. Edwardsii. 



The orange male of C. Christina has the primaries entirely, and 

 the secondaries nearly, covered with orange, which is at variance 

 with the description, " that about one half of the sj>ace inside the 

 border is occupied by orange." Only one of the males has below 

 a submarginal series of brown dots — as sometimes apj^ears in C. 

 Edwardsii. I have not seen C. Edwardsii with such an orange 

 patch, but as similar varieties are recorded for Palaeno from 

 Greenland by Scoresby, for Pelidne from Labrador by Moeschler, 

 for Philodice by Mr. W. H. Edwards, there is no improbability 

 that some may exist of Edwardsii. It would certainly need a 

 stronger proof to consider those males of Christina as a separate 

 species, the more so since they are associated with an undoubted 

 female of C. Edwardsii.
