objection to my determination. I possess a large white female of 

 C. eurytheme from Texas which has the secondaries yellow above, 

 and both wings with a yellowish tinge on the underside. Unfor- 

 tunately the figures of C. occidentalis in "N. A. Butt., Vol. i, Colias 

 vn, do not agree with the description (here also the silver discal 

 pots are black blots) in some characters. 



In comparing the detailed description of the white female by 

 Mr. Scudder, with which his types agree perfectly, with Mr. 

 Edwards' figures and descriptions of C. occidentalis, it is evident 

 that the latter's specimens do not belong to Mr. Scudder's species, 

 or else that his figures and descriptions are insufficient. There is 

 nothing in the figure or description of the yellow female different 

 from C. interior (Eclwardsii). I possess a male of this species 

 from Dease Lake, only a few miles distant from Fort Simpson, 

 and as no warrant has been given that the yellow female belongs 

 to the male except that they arrived in the same lot, this female 

 has to be considered as C. interior. The white female is C. 

 eurytheme, which flies at Fort Townsend also together with C. 

 occidentalis male, which last is synonymous with C. Scudderi. I 

 have to remark that one of the three males from Lake Labache 

 shows (like Mr. Edwards' specimens) the obsolete submarginal 

 series of f errugineous patches and the larger patch on the end of 

 the costa. 



According to Mr. W. H. Edwards, Canad. Ent. xiv, p. 56, he 

 saw a couple of C. occidentalis from Hudson's Bay.

In the eastern part of Washington Territory were collected in 

 Colville Valley, together with some C. Edwardsii, four males and 

 five females, July 23 to 25, half of them old rubbed specimens. 

 Mr. H. Edwards recognized instantly that they belong to his C.
