Mr. H. Edwards has kindly labelled several of my specimens 

 from Washington Territory, male, female and a white female, as 

 C. Eriphyle ; therefore there cannot be any question of the 

 identity of the specimens considered here. When the characters 

 given for C. Eriphyle are compared with the range of variations 

 observed by C. Philodice no difference is left, except canary 

 color (primrose H. Edwards) instead of sulphur yellow. 



I have before me ten males and five females from Umatilla, 

 Or., and Washington Territory along the Yakima river, Spokane 

 and Colville Valley collected from June 25 to July 25, together 

 with C. Edwardsii. The males have the black marginal band cut 

 to the edge (just as one Philodice from Coalburgh, W. Va., pre- 

 sented by Mr. W. H. Edwards) or not. On the underside they 

 represent all shades of variation of the series of submarginal 

 brown dots, complete or incomplete, or only indicated; the 

 brown clash on the outer angle is present or wanting. The discal 

 spot of the secondaries is as in Philodice. Mr. W. H. Edwards 

 states that this spot is only occasionally bright orange in C. Philo- 

 dice, but among the large number before me from the Eastern 

 States, more than half of them possess a bright orange spot. 



The yellow females are similar to C. Philodice. The black 

 marginal band is more dusted with yellow scales, but not much 

 more than in a female from Osage, Kansas ; the only white female 

 from Umatilla was fresh colored and has the secondaries below 

 grayish, but as the wings are still crumpled, the color may be not 

 well developed. 



Concerning the interesting question of the spreading westward 

 of C. Philodice, I may only state, that the collection of the 

 Museum possesses a number of typical C. Philodice collected at 

 Osage, Kansas, by Mr. Stolley before 1861.
