388 LEPIDOPTERA. 



Wilts sometimes commonly, as also in the Reading district of 

 Berkshire ; rare in Devon and apparently not noticed in 

 Cornwall. In Essex abundant in 180 J-, and found also in 

 Suffolk and Norfolk ; generally distributed over the fen and 

 chalk districts of Cambridgeshire and the adjoining counties, 

 and there also plentiful in its favoured seasons, when indeed 

 it has been known to occur in the suburbs of London ; 

 taken occasionally on the Cotswolds, Gloucestershire, in 

 Leicestershire, Derbyshire, Herefordshire, and rarely in 

 Lancashire and Yorkshire ; more frequently in Lincolnshire 

 and Durham. In Scotland it is very rare. Mr. Cameron 

 has recorded it in Ayrshire, and Dr. White in the Clyde, 

 Solway, and Forth districts. The only record in Ireland 

 seems to have been doubtful and has not been confirmed. 



Abroad its range is exceedingly wide ; Central Europe 

 and all the temperate portions of the northern part of the 

 Continent, Northern Spain, Northern Italy, Southern Russia, 

 Siberia, Tartary, India, China. Japan, North Africa, Canada, 

 and even Greenland.
