SERICORW.-E—SPILONOTA. 15 



The moth sits in rose-bushes during the day and is then 

 easily induced to fly ; but moves about of its own accord in 

 the evening and night, and comes readily to a strong light. 

 Common everywhere in the south of England to Leicester- 

 shire even sometimes most abundant along the beds of Rosa 

 spinosissima on the coast ; also frequent in the eastern and 

 western counties ; apparently rare or absent in some parts of 

 the Midlands, though found in Staffordshire, Cheshire, 

 Lancashire, Yorkshire, Durham, and Northumberland. In 

 Wales in Glamorganshire and Pembrokeshire ; in Scotland 

 in the Edinburgh district, Renfrew, Ayrshire, and Argjde ; 

 and in Ireland on the Dublin coast and in Derry. Abroad 

 all over Europe, and the trans-Caspian regions.
