and it vz especially common in the fens. It occurs in most of 

 the southern and eastern counties of England, but does not 

 seem to be recorded from other parts of the British Isles. 



Green Silver Lines {Hylophila prasimmd). 



The bright green fore wings are crossed by two shaded 

 silvery lines, and a narrow silvery band, the latter running from 

 the tip of the wing to the inner margin, and usually there is a 

 whitish shade between the two lines ; the fringes are reddish, 

 or pinkish, and the front and inner margins are tinged with the 

 same colour, sometimes strongly so on the inner margin. The 

 hind wings of the male are whitish, tinged with yellowish green ; 

 fringes white, more or less tinted with reddish ; in the female 

 the hind wings are entirely silky white. Antennte reddish 

 (Plate iz). 



Caterpillar, green, with yellowish dots, lines on the back, and 

 edging to first ring of the body ; the anal claspers are marked 

 above with red. It feeds in August and September on the 

 leaves of oak, birch, beech and nut (Plate 72). 



The chrysalis is purplish above merging into pale brown 

 beneath ; wing-cases ochreous brown ; the dorsal surface, 

 especially the ring divisions, are dusted with whitish dots. 

 It is enclosed in a papery cocoon of a pale pinky brown colour ; 

 frequently spun up on the back of a leaf, but also in a curled 

 leaf, bark chink, or among herbage and litter on the ground. 



The moth flies in June and July, and is not uncommon in 

 woods throughout the greater part of England, it may be beaten 

 from trees, and is often to be seen sitting on bracken and other 

 undergrowth. It is also found in Scotland up to Moray, and 

 seems to be pretty generally distributed in Ireland. The range 

 of this species abroad extends through Northern and Central 

 Europe, South Russia, Siberia, to Japan.
