3»o LEPIDOPTERA. 



recent discovery, or rather there ia reason to think that the 

 creature has within the last few years extended its range 

 m that direction ; but Sherwood Forest has long been re- 

 nowned as its home, and in very favourable years, such as 

 1872, upwards of one thousand specimens have been captured 

 without apparently affecting its abundance. In ordinary 

 seasons the vast majority of its larvae are destroyed by an 

 IcJmcumon parasite, and it is only when, from some un- 

 explained cause, this parasite fails that the moth attains its 

 natural increase. It has been taken rarely in Norfolk, 

 Lincolnshire, Worcestershire, and in Cannock Chase, 

 Staffordshire, and more freely in Cumberland. In Scotland 

 it is not rare in Morayshire, and casual specimens are 

 recorded from Perthshire and Inverness. The record in 

 Ireland has not been confirmed, and was most probably an 

 error. Abroad it has a wide range through Central Europe, 

 the temperate portions of Northern Europe, Northern Italy, 

 Southern Russia, and the mountainous regions of Central 

 Asia.
