The Purple-Barred Yellow Moth. 



This pretty species is common in most parts of Europe and 

 Asia Minor, but is rare in Britain. It expands about an inch. 



The fore-wings are olive-green in the male, but are generally 

 more golden yellow in the female, with two deep rose-coloured 

 bands. The first, which is near the base, is curved inwards, 

 and usually ends about the middle, but it may be continued 

 across the wings, especially in the female. The second band 

 is sub-marginal, and runs entirely across the wing. There is 

 frequently a rose-coloured lunule in the central area, which is 

 connected with the outer band. The hind-wings are golden 

 yellow, somewhat suffused with olive-green on the inner 

 margin, and have a narrow rose-coloured marginal line.
