42 LEPIDOrTERA. 



seen on July 13th. In 1868, a forward season, plenty of 

 freshly emerged specimens were on the wing on Jmie 30th, 

 and it is very probable that in that year also the old ones 

 may still have been out at the same date. 



Plentiful in the southern half of England, though not 

 noticed in the extreme south-west of Wales (probably from 

 absence of its food plants), but becoming scarcer towards the 

 north ; once seen in Durham, recorded also once — fifty years 

 ago — in Northumberland, and apparently once only in 

 Scotland. In Ireland it occurs in the south-west districts. 



Abroad, its range is wide in temperate regions of Europe, 

 Asia, and the north of Africa.
