" Ilahitat. Europe and Siberia, inhabiting peaty or boggy places and mountain sides. Its range in 

 Europe is limited to Germany, Scandinavia, Russia, and the Alps of Switzei'land. It does not 

 occur in "Western or North-western Europe. 



" Larva. According to Freyer, pale green, with short reddish hairs, the spiracles marked with 

 white, and the head dark browji or blackish. Its food-plant is Vaccinium oxyococcus, on 

 which it feeds in September and October, and again in the spring after hybernation." 

 {Lang, I. c.) 



There was a female specimen of this species in Fryer's collection which is 

 not referred to in his work. This example differs from the type in being 

 smaller and darker on the under surface ; it was probably taken in the 

 mountains of Central Japan or in Yesso. 



L. optilete has been recorded from various parts of Amurland, also from 

 Trans-Baikal.

" Expands 1-12 inch. Fringes of all the wings white. The male has the wings deep rich violet- 

 blue, with a narrow black border ; discoidal spots absent. The female has all the wings 

 uniformly brown in colour, without any markings. The underside is grey, slightly tinged 

 with greenish blue at the base in both sexes. The fore wings have a central row of black 

 spots, and an elongated discoidal surrounded with white. The hind wings have two rows of 

 large white spots without ocelli." {Lang, I. c.) 



The Western Chinese form of L. pheretes differs from the European type 

 in its larger size (34 millim.) and deeper blue colour in the male ; the black 

 margins are broader, and there is usually a series of black spots on the outer 

 margin of secondaries. Under surface paler, and the spots are generally less 

 distinct ; the white-ringed black spots forming a transverse series on primaries 

 are sometimes very distinct, but often only faintly indicated, and sometimes 

 entirely absent. 



The female differs only from European examples of the same sex in being 

 larger. 



In India L. 'pheretes is represented by var. lehanay Moore, which is smaller 

 and darker than the type, with broader margins to all the wdngs. The
