GREEN SILVER-LIN Ed. 261 



pillars are usually naked, and much attenuated 

 behind, which gives them some resemblance to a 

 fish ; whence some of them are described by Reau- 

 mur as Chenilles en forme de Poisson. They have 

 sixteen legs, and run with great activity, seemingly 

 with equal ease either backwards or forwards. The 

 species above referred to expands from somewhat 

 more than an inch to an inch and a half, the colour 

 light-green ; each of the anterior wings with three 

 oblique stripes of silvery-white, the costa likewise 

 of that colour. The abdomen and hinder wings are 

 yellowish-white; antennaa reddish-brown; the an- 

 terior margin of the upper wings, the hinder margin 

 and the fringe, as well as the legs, tinged more or 

 less with bright red in the male. 



The caterpillar is light-green, with a yellow line 

 on each side, and two red streaks behind. (PL xxix. 

 Fig. 3.) It feeds on a variety of common trees, 

 and changes into a reddish-brown pupa, which it 

 encloses in a closely woven cocoon, nearly boat- 

 , shaped. The moth is not rare in England, and is 

 likewise found not unfrequently in the south of 

 Scotland.
