verse lines in front. The fore-wings are yellowish-grey, 

 clouded with ashy-green, brown, and whitish, and marked 

 with sinuous black lines, most of them running obliquely 

 across the wings. These represent the half-line, two trans- 

 verse lines, and the sub-marginal line. The central area is 

 pale, and contains a grey reniform stigma, centred with brown. 

 There is a double row of dark spots on the hind-margin. 

 The hind-wings are deep ochre-yellow, with two black bands, 

 neither of which extends as far as the inner margin. The 

 outer is the broader, and the inner is constricted in the 

 middle of its length. Beyond the outer band the wings are 

 yellow, with yellow fringes. Both the fore- and hind-wings 

 are distinctly dentated. The abdomen is yellow, like the 

 hind- wings. 



The female is more clouded than the male, with a trace of 

 reddish. 



The larva feeds on the Black American Walnut (Juglans 

 nigra), and, like its European allies, when it has done feeding, 

 it descends from the leaves to the trunk of the tree, and 

 stretches itself along the bark, to which it bears so much 

 resemblance in colour and texture that it is scarcely distin- 

 guishable from it. It is greyish-brown, or reddish-brown, with 

 a black dorsal line, marked with a white spot on each segment, 

 and a sinuous black line above the spiracles. The head and 

 legs are concolorous.
