part of the day they may be found lurking at the 
sides of stones and among grass, and when an 
attempt is made to seize them, they do not take 
>ving, but attempt to escape by gliding rapidly 
among the herbage. The most abxmdant species 
is that named the Great Yellow Underwing (T. 
pronuba J, which occurs plentifully in all parts of 
Britain. That which we have figured is much less 
frequently met with, but it inhabits numerous and 
widely scattered localities, having been foimd in 
Northumberland, Yorkshire, Devonshire, Sufiblk, 
&c. It is nearly of the same size as the common 
species ; the head, thorax, and anterior wings grey- 
ish, dark liver-coloured, or some shade intermediate 
between these two, each mth four transverse pale 
lines, and tw'o pale rings on the disk ; the line next 
the base abbreviated, the second and third angulated, 
and enclosing a space darker than the rest of the 
wing in which the two annular marks are placed ; 
the hinder one undulated, having one or two black 
dots at its anterior extremity, surmounted by a few 
white ones. The underwings are light orange 
yellow, with a very broad posterior band of deep 
black, which, however, does not cover the hinder 
edge : the abdomen likewise yellow ; the antenn® 
brown, ivhitish at the base. 
The caterpillar is large, rough, and ochrey-yellow, 
with a pale line along the back, and white stigmata 
surrounded with a black ring. It feeds on the 
potato, violet, hound’s tongue, primrose, &c. The 
moth is found in June and July.
