Godman and Salvin are two females from the Amur of the 

 pale form, figured by Eversmann, Bull. Mosc. 1847, 

 t. 4, figs. 3 and 4, as G. cliloe. This form is evidently the 

 analogue of the var. lielice in C. edusa. 



Females appear to be rare, as there are none in the 

 Hewitson or British Museum collections. 



As regards G. chrysotheme, Esp., it seems to agree very 

 closely with some of the varieties of Eurytheme from 

 California and Texas, though, if we consider it as the 

 same species, the geographical distribution is remarkable, 

 Chrysotheme being confined to South-Eastern Europe, 

 some parts of Asia Minor, and Eastern Siberia. I cannot 

 distinguish between specimens of Ghrysotheme from Pesth, 

 and of Keewaydon from California.

G. Ghione Curt., 1. c. p. 66: 



This species or variety is only known from the speci- 

 mens collected in Captain Ross's second expedition to the 

 arctic regions, at Repulse Bay and in Boothia-felix, where it 

 is said to be abundant for about a month in July and 

 August on Oxytropis campest7is, and 0. arctica, which 

 are probably the food plant of the larva. 



They have been considered by all writers as a good 

 species, on account of the very narrow border of the wings, 

 which is entirely absent in the var. Chione. 



I am doubtful, however, whether this last, of which 

 three specimens from Repulse Bay are in the British 

 Museum collection, are not rather a form of C. Boothii, or 

 a hybrid between that and Nastes.

This species, which is found on the high fells of Lap- 

 land, in Greenland, and Arctic America, is, from my point 

 of view, only a dwarfed local race of G. Edusa. 



The variety of it described by McLachan from Hayes 

 Sound, lat. 79° N., and from Grinnell Land in lat. 81° 45' N., 

 are probably the most northern specimens known of this 

 germ, and are much paler in tint and duller in their mark- 

 ings than the Lapland variety.
