BRITISH BUTTERFLIES. 



Papilio machaon. SWALLOW-TAIL. 



1. This beautiful insect formerly inhabited many 

 counties of England, but the drainage of the fens has so 

 limited the borders of its haunts that it is now almost 

 exclusively confined to the fen districts of Cambridgeshire, 

 Huntingdonshire and Norfolk; and it is to be feared that 

 as the drainage continues it will in time become extinct* in 

 our islands. Unknown in Scotland and Ireland. 



2. Hog's Fennel (Pcnccdannm palustye), Cow -parsnip 

 '(Hcrachum sphondylium), and Wild angelica (Angelica sylvcstris) 

 in confinement, Rue and Carrot. 



3. May to August. 



4. Fens and marshy places. 



* Happily in the Norfolk Broads this is not likely to occur for many 

 vears to come. 



Aponia cnataegi. BLACK-VEINED WHITE. 



1. Formerly common in several localities in the South 

 of England, but at all times local ; now very rare, and 

 restricted to the county of Kent, but perhaps may still exist 

 in South Wales. Unknown in Scotland and Ireland.* 



* Possibly not really indigenous.
