Scudder afterwards received for examination a specimen from 

 Moose River by Mr. W. H. Edwards, who also notes C. interior 

 taken in Vancouver's Island by Mr. Crotch, Tr. Ent. Soc. Phil. 

 v, p. 15. 



Mr. Scudder's description, which I have most carefully com- 

 pared, is thoroughly exact in every detail. The only addition to 

 be made is the existence of a small pink spot on the base of the 

 underside of the secondaries in all males and the female. I feel 

 myself obliged to state that I owe to the study of Mr. Scudder's 

 excellent paper — it was his first scientific paper — and to the 

 sound philosophical views contained in them important informa- 

 tion. 



The males of C. interior agree in size, in color and pattern with 

 the specimens .of C. Edwardsii which have the discal spot of the 

 primaries more or less rudimentary and the secondaries below 

 yellow. I have similar specimens from Washington Territory 

 before me. One of the male type has the marginal band of the 

 primaries larger, and its inner edge varies between erose (see 

 Mr. Scudder's figure) and more regular. The discal spot of the 

 primaries is wanting in one male. Concerning the female, which 

 is much rubbed, I possess similar ones but with a more yellow 

 tinge from Colville Valley. The cut of the external margin 

 belongs to the form of C. Edwardsii with a more rounded costal 

 angle of the primaries, followed by a more convex margin ; but 

 two of the types have the margin less convex, nearly oblique. 



Mr. Scudder has objected to the identity of C. interior with 

 C. Pelidne Bd-.Lec. p. 66, pi. 21, f . 4, 5, and Bd. Icon. p. 41, pi. 8, 

 fig. 1-3. Plate 21 in Bd.-Lec. is apparently a rather inferior one, 

 in comparing the fig. 1-3 said to represent C. Philodice. The 

 figure of C. Pelidne, fig. 5, fails to agree in two characters with the 

 description — discal spot papille de rougeatre et un point rouge- 

 atre a la base ailes — and the statement " un peu plus grande que 

 la C. Paleno, a laquelle elle resemble beaucoup." The comparison 

 with C. Palaeno is misleading and the statement that the discal 

 spot of the primaries below is " rougeatre " and of the secondaries 

 " rouge au lieu d'etre d'un blanc argentin, surmonte dans le male 

 d'un autre point semblable, mais beaucoup plus petit," does not 

 agree with the types of C. interior. Boisduval gives as habitat
