582. Colias pelidne, Bd., var. Skinneii, Barnes. — This form should 

 not be associated with interior, which I Hsted in error as pelidne, Mrs. 

 Nicholl says that this is a very common butterfly over the wliole of the 

 higher Rockies in August, from about 5,000 to 6,500 feet. It may be 

 taken right up to the timber Hne. She found it far north of Laggan in 

 1907. 1 took a specimen on Fairview on July 19th, 1904. I have a male 

 from Yellowstone Park, one of the type localities. This sex resembles 

 that of Scudderi, and it is compared with that species in the description. 

 But in females of Skiimeri the outer border somewhat resembles those of 

 interior^ whereas the female of Scicdderi is nearer to that of Alexandra, 



583. Pyrgiis cefitaurece, Ramb. — I took two worn specimens on Mt. 

 Piran on July 20th, 1904, one at Agnes Lake, the other about 1,000 feet 

 above it and above the timber, = 7,500 feet. One of these has been 

 labelled " centatcrece undoubtedly " by Dr. Skinner. Mrs. Nicholl, during 

 the whole of her 1904 trip, only took one specimen, " very high up, above 

 Lake Louise." Li 1907 she took one on Brobokton Pass in August, 

 which was possibly a second brood. She says : " I have two that 

 Simpson got me early in May." Mr. Jim Simpson was her guide and 

 packer. I took a splendid specimen below timber line on a mountain 

 about eight miles south-east of Windermere, B. C, on July 13th last, 

 flying with worn ccespitalis. It is not on the B. C. list, though recorded 

 from that Province in Holland's book.

PENNSYLVANIA. 



BY AUGUST BUSCK, U. S. NATIONAL MUSEUM, WASHINGTON, D. C. 



Gnorimoschenia alaricella, n. sp. — Labial palpi whitish, sprinkled 

 with blackish scales, especially externally; terminal joint with a black spot 

 at the base and a broad black annulation just before the tip. Face, head 

 and thorax white, heavily sprinkled with fuscous. Fore wings with the 

 bluish-white ground colour nearly obscured by darker scaling of black, 

 dark fuscous and brown, which suffuses the wing without definite pattern, 

 though with the effect of diffused longitudinal streaks. On the middle of 

 the wing is a very indistinct brown ocellate spot, with black centre, and on 

 the fold below it is another similar but still less distinct spot; both of these 

 are easily effaced and lost in the general dark scaling. Cilia gray. Hind
