covers closely com])acted and vmWv smooth; wino-covers 

 silky, not visibly sculptured, but showing the wing-ner- 

 vures distinctly in raised ridges ; dorsal region roughened ; 

 abdomen regularly tapering, curiously roughened and dull. 

 except the smooth' hinder edge of each segment ; cremaster 

 thick, elongated, and very blunt, semi-divided by a deep 

 dorsal longitudinal suture, tipped with minute curled bristles. 

 Colour pale brown, rather darker on the l»ack. but with a 

 white stripe along the back of each wing-case. Occasionally 

 it also is foiuid of a bright green colour with white mark- 

 ings. 



On, or under, a leaf of beech, placed upon a silken carpet 

 to which the cremaster is attached, and held in its place by a 

 silken thread across the back. 



The winter is passed in this condition. 



The moth sits during the day, occasionally upon the trunks 

 of beech-trees, very much more frequently among the leaves 

 in the low thick branches, from which it is easily disturbed, 

 but not necessarily so easily captured, since it often Hits away 

 into some higher portion of the tree. At dusk it tiies about 

 the trees, and it does not often come under the notice of the 

 eager collector at that time. Formerly it was to be found, 

 occasionally, in the London suburbs, but apparently has quite 

 forsaken them. Almost contined to beech woods, and in them 

 often abundant, in Kent, Sussex, Surrey, Hants. Wilts. Berks, 

 Oxfordshire, Bucks, and Essex ; scarce in Dorset and Devon, 

 and also in Norfolk, Suffolk, and Cambridgeshire ; found 

 locall}- in Gloucestershire, Herefordshire, Worcestershire, 

 Cheshire, Lancashire, and Yorkshire ; and it has been taken 

 once in Durham, and once in Northumberland. I am not 

 aware of its occurrence elsewhere in the United Kingdom. 

 Abroad it is found throughout Central Europe. Northern 

 Italy, Corsica, Livonia, and Southern Russia.
