a silvery blue (Bois. says argento-aer niece); and in the female the color of 

 Scepio/iis is fuscous, with more or less blue at base. 



Boisduval describes Icaroides as subviolaceo-cceru/ece, the $ fuscce. 

 For Rufcsccns ^ he says shining blue, nitide cceridece. The former is of 

 a dull violet blue, the fringes not pure white, rather ashen-white. The 

 latter is metallic pruinose blue, as I see it, with white fringes, and these 

 contrast prettily with the blue. Placed side by side there is no mistaking 

 one of the males for another in those three species. 



NOTES ON COLIAS CHRISTINA, Edwards. 



BY H. H. LYMAN, iMGNTREAL. 



Dr. Hagen, in his paper on the genus Colias,^' recently published, dis- 

 cussing the species described by Mr. Wm. H. Edwards under the name 

 of C. Christina, comes to the conclusion that it is merely a variety of C. 

 Edwardsii, which, he regards as only a form of C. Interior, Scud., in- 

 cluding also under the latter name, Emilia., Astrcea, Scudderi ,Alexandra, 

 Occidentalis, Harfordii and Laurentiiia. 



I had the good fortune last year to receive from my friend. Dr. Robert 

 Bell, of the Geological Survey, a series of fifteen specimens of this 

 species, which, although not perfect, are very valuable for study ; collected 

 at eight locaUties in the North-west Territories, extending over 250 miles 

 of trail, the most south-easterly locahty being Qu'Appelle, 50° 40' N., 

 104° 14' W., and the most north-westerly, Duck Lake, 52° 47' N., 106° 

 15* W. The series consists of 6 males and 9 females. Mr. Edwards 

 described and figured one type of female which is apparently not the 

 most usual one, in fact none of mine answer to the description given by 

 him. The most usual form, as represented by six out of the nine, may 

 be described as follows : 



Expands 2-2]^ inches. A dwarfed specimen was only \\% inch. 



Upper side lemon yellow, slightly suffused with orange, especially on 

 primaries, which have a broad marginal band enclosing a row of yellow 

 spots, which are sometimes defined, but more frequently united into an 

 irregular band. Discal spot generally larger than in the male, black,
