When I first met with these species, I took B. euphrosyne in 

 a clearing in a wood in Sussex ; and on revisiting the spot a few 

 days later, took B. selene. I afterwards took the latter species 

 by the side of a wood close to Brighton, where I never saw 



Under side of a variety of B. selene. 



B. euphrosyne ; and I have always found B, selene far more 

 abundant than B. euphrosyne near Diisseldorf, in Germany, 

 especially in autumn, when it is one of the commonest Butter- 

 flies in the woods.

The present species derives its English name from Richard 

 Weaver, a celebrated collector and dealer in English insects, 

 who flourished fifty or sixty years ago. He had a specimen 

 which he believed to have been taken by himself in Sutton
