TBTHBA RETUSA. 81 



beneath ; the head small, rounded, and rather flat ; 

 shin very delicate and thin, so that the lines on it 

 show almost as if ribbed or raised, and the internal 

 organs partially show through it. The colour is a pale 

 dull green, with a yellow tinge towards the head and 

 tail ; a broad dorsal stripe, a fine subdorsal, and an 

 undulating spiracular line, all whitish in colour; the 

 spiracles not visible ; the head generally yellowish- 

 green, but sometimes very dark blackish-brown; occa- 

 sionally also there is a dark collar on the second seg- 

 ment ; young larvse sometimes have the usual dots, 

 very visible and black, but lose all trace of them as 

 they grow bigger. 



The characters printed above in italics distin- 

 guish this larva from that of Epunda viminalis, which 

 has a much firmer texture of skin, a thicker and more 

 corneous head (which is pale grey with the lobes out- 

 lined in black) ; the lines more sharply defined, and 

 two pairs of whitish dots on the back of each segment.

ElJPERIA FULVAGO. 



Plate LXXXVI, fig. 1. 



For many years Sherwood Forest in Nottingham- 

 shire was considered the only British locality where 

 this pretty species could be taken in numbers. There 

 it used to be, and I suppose still is, a most abundant 

 moth. Odd specimens were very occasionally taken in 

 other and very widely separated localities in England 

 and Scotland, but it was not until 1888, when Mr. J. 

 N. Young, ofRotherham, and his friends, took twenty- 

 six specimens in Wad worth Wood, near Doncaster, 

 that another locality was found where it could be relied 

 on to occur in some plenty, as the two seasons which 

 have elapsed since then have sufficiently proved.
