faint tino'e of green is so evanescent that it is only visible on 

 specimens which, when captured, were freshly emerged, or 

 have been reared, and also completely protected from damp. 

 On the wing in the latter part of May and in June. 



Larva very long and slender, rigid, anal tia]) produced 

 prominently behind ; head large, deeply bifid, and flattened 

 in front, dark red ; face whitish ; body bright grass- green, 

 undersurface paler ; incisions of tlie segments rather paler ;. 

 at each, on the back, is a bright ferruginous spot shaded on 

 each side with yellow ; second segment furnished with two- 

 projecting ])oints. (C. Fenn.) 



August to October on oak, birch, hazel, sallow, dogwood, 

 hawthorn, Genista, and sometimes on herbaceous plants ;. 

 feeding at night; remaining upon its food-plant, rigidly 

 extended, during the day. 



Pupa very slender, with prominent eye-covers, and a 

 rather sharp cross-ridge in front of them ; antenna-cases 

 long and very prominent at the shoulders, showing the shaft 

 and pectinations ; wing-cases rather long, the nervures pro- 

 minently indicated ; abdomen long, gradually tapering, 

 curved back ; anal segment hollowed beneath ; cremaster 

 tapering, long and slender, bearing some hooked bristles 

 colour bright pea-green ; wing-covers more glaucous green ; 

 eye-covers and cremaster brown. In a very slight cocoon 

 formed of a few threads in the drawn-together corner of a. 

 dead leaf, but holding fast by the anal hooks. 



In this condition through the winter. 



The moth hides during the day among the leaves of its 

 food-plants, especially preferring the lower bushes, and may 

 readily be disturbed by the beating-stick ; but it shows no 

 alarm, being one of the weakest in flight of the Gcomdridcc, 

 and simply flutters into a neighbouring bush. Its natural 

 flight at dusk is equally weak, about the same bushes. A 

 constant inhabitant of the more open woods, and found in
