 Venanson ; Mt. Colmiane ; Mt. Balme de la Frema, 

 and many other places. Common. 



OVUM, Eggs in August. 



LARVA. On Viola canina and Polygonum bistorta,

P. bistorta is not mentioned in the books as a food- 

 plant of the species, though larvae were found in 

 abundance on this plant, on the Colmiane, on 

 July 1 st 1889. 



The butterflies emerged three weeks afterwards. I do 

 not possess any imagines from caterpillars found on 

 this occasion, but have seen several of them, which 

 appear smaller in size than those from a lower elevation. 



VARIETY. ab. Charlotta, ?. 



In this form, " the silver spots on the u.-s. are 

 larger than in the type, there being especially three 

 large basal silvery blotches ; occasionally the spots of 

 the central row coalesce to form bands." (Lg.)
