LA RE\TID.'K~E I 'PIS TERIA. 207 



The moth sits during the day upon the trunks of wych- 

 elm, fir, and beecli trees in woods, and is there very con- 

 spicuous, of whicli circumstance it seems to be well aware, 

 since it is restless. Hying ofE immediately when approached. 

 But ilr. J. E. Robson tells me that in the north of England 

 it prefers to sit upon the upper sides of herbaceous plants, 

 such as Enchanter's Nightshade, in the daytime, resorting to 

 the trees only in rough weather. It seems to be rpiite 

 absent from the eastern half of the South of England, but 

 about woods where wych-elm is found it is cpiite common iu 

 Somersetshire, and in the Cotswold district and the Forest of 

 Dean in Gloucestershire, is found rarely in Devon, locally iu 

 Wilts, Bucks. Oxfordshire, Herefordshire, Worcestershire, 

 and Salop ; also in the Midlands in Staffordshire ; and Dove- 

 dale, Derbyshire ; farther north in Yorkshire, Lancashire, 

 Cumberland, and Durham, sometimes occurring quite com- 

 monly iu Castle Eden Dene and Hasleden Dene iu the last- 

 named county. In Wales Mr. A'ivian has found it in 

 Glamorganshire, and it is recorded in Merionethshire ; but ] 

 have no knowledge of its presence iu eithei' Scotland oi- 

 Ireland. 



Abroad it is also very local, but is found in Germany ami 

 Livonia, in the Ural JMountain region, in Tartary, Japan, and 

 the hill countries of India.
