114 LEPIDOPTERA. 



suming one surface of the leaf, as well as the substance, 

 leaving the transparent skin of the other surface ; or, in the 

 case of very young leaves, eating them through. 



Pupa stout, blunt behind, rather pointed in front, having 

 long, well defined wing-cases, and the leg-cases so long as to 

 extend rather beyond the hinder extremity ; colour brown. 

 In a thin, white, tough but filmy cocoon, attached to stems 

 of plants, close to the ground. 



An exceedingly local species, frequenting meadows, and 

 often to be found in hundreds in one corner of a pasture 

 while hardly a specimen can be found in other parts of the 

 field or in those adjoining. Generally sluggish, though the 

 males fly freely enough, a few yards at a time, in the bright 

 sunshine ; but usually found sitting on flowers and grass- 

 blades. 



Common in suitable places in the southern and south-mid- 

 land counties to Gloucestershire, Cambridgeshire, and North- 

 amptonshire ; scarce in Norfolk and Sufl^olk, though found 

 in some years commonly in one spot near King's Lynn ; un- 

 common in Devon and Somerset ; also to be found in Here- 

 fordshire, Staffordshire, Derbyshire, Cheshire, and Lancashire ; 

 and in East Yorkshire rather commonly. Probably there are 

 few English counties in which it has not a secluded home, but 

 there is a singular absence of records in Wales. It is found in 

 Dumfries-shire and some other parts of the south of Scotland ; 

 in the neighbourhood of Oban, and in several other localities 

 in Moray and Argyleshire, the latter district producing 

 specimens of large size and singularly blue-green colour. 

 In Ireland it was found in abundance some years ago in the 

 county Wicklow by the Kev.» J. Bristowe, and has also been 

 met with in Clare and Westmeath. 



Abroad it is common in the South of France, Northern 

 Italy, generally in Central and Northern Europe, Spain, South 

 Russia, and Armenia.
