I go LEPIDOPTERA. 



blackish, mouth brown ; body bright green, pale green, or 

 yellowish-green irrorated with pale yellow ; dorsal line 

 distinct, white on the second to fourth segments, thence 

 yellow ; subdorsal lines whitish or yellowish, less distinct ; 

 spiracular stripe broad, whitish, yellowish, or greenish-white, 

 very prominently edged and shaded above with black, 

 spiracles white, edged with black ; legs pale green, dotted 

 with brown ; prolegs tipped with pink ; incisions of the 

 segments yellowish, (C. Fenn.) 



April to June on oak, sallow, hawthorn, blackthorn, willow, 

 lime, and other trees and shrubs — even laurel — and also on 

 various low-growing plants. Feeding mainly at night, but 

 remaining upon the food-plant during the day. 



Pupa stout, rounded, shining ; two diverging bristles 

 behind ; dull mahogany-red ; wing-cases paler. Subter- 

 ranean, in a hard brittle earthen cocoon. (0. Fenn.) It is 

 a curious circumstance in this and several of the allied species 

 that the motli is developed in the pupa in the late summer or 

 autumn, and remains in this condition, within the pupa-skin, 

 until its proper time of emergence in the spring. This does 

 not seem to be a beneficial habit, since a very considerable 

 proportion are found to die without emerging. 



The moth hides during the day among herbage or fallen 

 leaves, except under some influence with which we are 

 unacquainted, when it will fly vigorously in the sunshine and 

 feast upon its favourite food. This occurs but seldom, and 

 I have never seen such a circumstance, but the late Mr. H. 

 Doubleday observed it on several occasions in Epping Forest. 

 Its ordinary time of flight is early dusk, when it gathers 

 in multitudes to feed on the sweet fresh blooming catkins 

 of the sallow, especially Salix ccqwca, in the open glades 

 of woods and in open wooded districts. Later, as the 

 sallows fade, it frequents the blossoms of plum and black- 

 thorn, but is scarcely ever to be taken at sugar. But when 

 the sallow-bloom is in its full freshness, in the first nights of
