The front wings of the moth (c. Fig. 95) are of a glossy, 

 dark ash-gray color, the hind wings a little paler ; when its

 stages, and it is probable that both insects are slightly-modified

 the edges meet, so that the whole leaf forms a hollow case, 

 within which it lives and feeds on the softer tissues. The 

 larva is of a yellowish-green color, with a yellow head, and
