1 64 LEPIDOPTERA. 



stalking. On heaths, which it sometimes frequents, its habits 

 are similar. At night it flies again and pays another visit to 

 the flowers. 



A very local species, sometimes to be found in plenty in 

 one or two fields, and hardly to be seen elsewhere for miles ; 

 also rather irregular in its appearances — perhaps from the 

 habit of the pupa of often lying quiescent till a favourable 

 season. Formerly said to be abundant on heaths near 

 Farnham, Surrey ; still in that county, but less common ; 

 also to be met with, in the uncertain manner already stated, 

 in Kent, Sussex, Hants, Dorset, Cornwall, Somerset, Glou- 

 cestershire, Essex, and particularly in the district of the 

 "Breck" sands of Cambridgeshire, Suffolk and Norfolk; in 

 the latter county it has also been found on the coast sandhills 

 near Yarmouth. Beyond this range it is very rare, but has 

 been recorded from Sherwood Forest, Nottinghamshire, and 

 in single examples from Yorkshire and Derbyshire. Appa- 

 rently quite absent from Wales, Scotland, and Ireland. 

 Abroad, however, it seems to extend over the whole of the 

 Continent of Europe except the extreme north, Northern 

 Africa, and a large portion of Asia, including India.
