PHYCiriDM—SALEBRIA. 429 



Pupa nearly half an inch long, having a rather iDointed 

 appearance, caused by the abdomen tapering rapidly to the 

 last segment, which ends in a rather sharp point ; all the 

 parts prominently defined ; the surface highly polished ; 

 black. (G. T. Porritt.) 



In a chamber formed of spun-together leaves. In this 

 state a fortnight or three weeks. 



The moth sits in the day in birch bushes, and may occa- 

 sionally be beaten out and captured, but in all probability it 

 usually drops to the ground without opening its wings ; and 

 its black colour renders it practically invisible at dusk, but 

 it will come to a strong light at night. Still the vast majority 

 of specimens in collections are obtained by rearing the pretty 

 larvtB, which are so easily collected. It is a local species, 

 preferring the birch bushes which gi-ow scattered about sandy 

 heaths ; and in such places is sometimes common. Found 

 in Kent, Sussex, Sui-rey, Hants, Wilts, Somerset, Herts, 

 Essex, Sufiblk, Norfolk, Warwickshire, Staffordshire, 

 Gloucestershire, Herefordshire, Worcestershire, Cheshire, 

 Lancashire, South Yorkshire, and once in Durham. This 

 appears to be the extent of its range in these Islands. Abroad 

 it is found throughout Central and Northern Europe.
