BOA RMIDJ-:— TEFHROSIA . 177 



Pupa elongate, pointed, anal extremity provided with a 

 projecting bristle ; colour red-brown ; wing-cases greenish. 

 Subterranean, enclosed in a delicate, thin, irregularly-shaped 

 cocoon of silk and sand. (C. Fenn.) 



In this condition through the winter. 



The Rev. Joseph Greene says that this is one of the few 

 species of which the pupa may often be found under moss- 

 along the spreading root>^ of trees. 



The moth sits during the day upon the upper portions of 

 trunks of trees, or even on branches, and seems to prefer a 

 height of from fifteen to twenty feet. Curiously enough it 

 seems greatly to prefer the trunks of Scotch firs, on which it 

 is sufficiently conspicuous ; but will also sit on those of birch, 

 beech, and oak. If disturbed by means of a long switch, 

 it will often flutter lazily down, or go further with the wind 

 to be lost upon the ground, whence it gets up again after a 

 time to return to the trees ; but if the weather is hot it will 

 dash rapidly away to settle out of reach elsewhere. The 

 female is almost as lively as the male at this time. The 

 natural flight takes place at dusk, but is seldom observed ; 

 doubtless the moths fly rather high and in woods are difficult 

 of observation. It is a very local species, found only in 

 woods, and by no means in all — even large — woods. So far 

 as I am able to judge, it prefers beech-woods on chalk, or 

 woods of birch, oak, and Scotch fir in sand districts. With 

 these limitations it inhabits Kent, Sussex, Surrey, Hants,^ 

 Dorset, Devon, Cornwall, Gloucestershire, Oxfordshire, Bed- 

 fordshire, Buckinghamshire, and Essex, and is rare in Suffolk. 

 There are a very few records for northern counties, which 

 are believed, or known, to be erroneous. In Wales it 

 is found in Glamorganshire ; and in Ireland in Cork, 

 Kerry, and King's County. Abroad it has a considerable 

 range through France, Belgium, Germany, Switzerland, 

 Austria, Hungary, Northern Italy, Southern Russia, and 

 Tartary.
