3S LEPIDOPTERA. 



iu Cornwall. It was formerly not rare in the London suburbs, 

 and probably still occuj's. In the Midlands it is found fairly 

 commonly in Warwickshire, Leicestershire, Derbyshire, and 

 Staffordshire ; and in the west in Herefordshire, Cheshire, 

 and Lancashire ; northward it is common in Yorkshire, and 

 found in Cumberland. It surely cannot be absent from Wales, 

 yet I have no record, and feel satisfied that it does not occur 

 in the Pembroke district. Very widely distributed in 

 Scotland, occurring in Ayrshire and other parts of the Clyde 

 district, and in those of the Solway, Tweed, Forth, Tay, Dee, 

 Argyle, Moray, West Eoss, and the Orkneys. Found through- 

 out Ireland, and in many parts common. Abroad it inhabits 

 all the temperate portions of Northern Europe, Central 

 Europe, Northern Italy, and Western Siberia ; also North 

 America, occurring commonly in Canada, the Northern and 

 Eastern United States, Colorado, Utah, and Montana, where 

 the specimens are rather lai'ge, and are known as N. luiruspica.
