DEMAS. 205 



American species are also included in this genus, which is of 

 somewhat doubtful position, having been referred by different 

 authors to the Notodontid(E^ Lasiocampidce, or Noctua^ as well 

 as to the Liparida. The name Colocasia is properly rejected 

 by Stephens on account of its having been previously used in 

 Botany.

The Nut-Tree Tussock is found throughout the greater part 

 of Europe. It expands from i*^ to ij^ inch. It is a reddish- 

 brown Moth, with the outer half of the fore-wings ashy-grey. 

 There are several black zig-zag transverse lines, an orbicular 

 stigma enclosed in a black ring, and a reniform stigma, which is 

 bounded with black towards the base. The hind-wings are 

 pale brown without any markings. 



The full-grown larva is light reddish-brown or pale flesh-
