This is a widely distributed, but local species, inhabiting 

 many parts of Europe and Northern and Western Asia, and 

 frequenting rocky places in May and June. It is dark brown 

 above, with the fringes spotted with white, and the base of the 

 wings purplish-blue in the male, most broadly on the fore- 

 wings. There is a large black discoidal lunule on the fore- 

 wings. The hind-margins of the fore-wings are marked with 

 rows of more or less distinct bluish-white spots, and the hind- 

 wings are marked with indistinct black spots in bluish-white 

 rings. The under side is bluish-white, with large and con- 

 spicuous black spots, consisting of basal spots on both fore- and 

 hind-wings, discoidal lunules, a row of spots bayond, and a 

 double row of sub-marginal spots, separated on the hind-wings 

 by a broad orange band. 



The larva is sea-green, with a violet dorsal line, and feeds 

 on Telephium.

 and African Butterflies of a white colour, slightly tinted with 

 blue, and with blackish borders, and black spots and bands 

 on the under side. The hind-wings are provided with a short 

 and slender tail. The type is
