BROAD -BORDERED YELLOW UNDERWING. 223 



part of the day they may be found lurking at the 

 ides of stones and among grass, and when an 

 rttempt is made to seize them, they do not take 

 wing, but attempt to escape by gliding rapidly 

 among the herbage. The most abundant species 

 is that named the Great Yellow Underwing (T. 

 pronuba)) 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 found in 

 Northumberland, Yorkshire, Devonshire, Suffolk, 

 &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 with four transverse pale 

 lines, and two 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 antennas 

 brown, whitish 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.
