This genus has numerous representatives in Europe; fifteen 
species are enumerated in Staudinger’s Catalogue, the nomen- 
clature of which I implicitly follow. Bainbur has separated them 
into many more species; indeed the genus remains in an uncertain 
condition as regards its division into species, and is perhaps in 
this respect the most difficult of all the genera of European 
butterflies. Only one species, S. Malvce, occurs in Britain.
