DINGY SHELL. 219 



The moth flies in June and July, and in the daytime may be 

 readily disturbed from hedges in localities on the chalk in the 

 southern half of England and Wales, especially in the seaboard 

 counties from Kent to Cornwall. It has been recorded from 

 Derbyshire and Yorkshire, and once from the Isle of Arran

The Streamer {Antidea nigrofasciaria). 



The two examples of this species depicted on Plate 88 show 

 the ordinary form with the central area of the fore wings greyish 

 brown (Fig. 7, Essex), and a New Forest specimen in which the 

 central area is whitish (Fig. 8). 



The long caterpillar is green, inclining to yellowish between 

 the rings ; a purplish, or reddish-brown, stripe along the back 

 is broken up into spots on the middle rings. It feeds on the 

 flowers and leaves of wild rose, and can be found or beaten out 

 in May and June. (Plate 89, Figs. 2, larva, ia^ ova.) 



The moth is out in April and early May, and is often seen at 

 rest on pahngs, etc., but it occurs chiefly in hedgerows, along 

 which it flies at dusk. 



This species (also known as derivata^ Borkhausen) is pretty 

 well distributed over England, Wales, and Scotland up to 

 Sutherlandshire. In Ireland it seems to be local. 



Dingy Shell {EticJmca obliierata). 



This pale ochreous brown species (Plate 91) is in the male 

 (Fig. i) more or less sprinkled and shaded with darker brown, 

 and the three brown cross lines are consequently often obscure, 

 and rarely as distinct as in the female (Fig. 3). 



The green caterpillar has a yellow line running down the 

 middle of a black stripe along the back, and this stripe is
