As there is such a slight description of the larva of 

 this species in Newman's British Moths, I think a 

 more complete one will not be considered out of place 

 in the pages of the Entomologist. I may say here, 

 that although I have reared a large number of these 

 larvae, I have never seen any of the "green-tinted" 

 forms mentioned by Mr. Newman. This year I fed 

 up two broods from eggs obtained from moths cap- 

 tured last season, and from them the following notes 

 were taken. 



The eggs were deposited about July, 1874, and 

 began to hatch on the 3rd of April of the present 

 year. 



The newly emerged larvae were dark greenish- 

 brown, the sides yellowish-green, and the head dark 

 wainscot-brown. 



They fed up well on bilberry, and on the 3rd of 

 June, being full-grown, their description was taken 

 as follows : 



Length about an inch and a quarter, and of average 

 bulk in proportion. The head has the lobes rounded, 

 but is rather flat in front, and is slightly broader than 

 the second segment. Body tolerably, but rather un- 

 evenly, cylindrical, tapering a little towards the head ; 

 there is a slight lateral ridge, which on the third seg- 

 ment takes the form of a distinct swelling. The skin 

 has a tough appearance and is rather rough ; there 

 are a few exceedingly minute hairs upon it ; the 

 segments slightly overlap each other, rendering the 

 divisions distinct. The ground colour varies in dif- 

 ferent specimens from a median shade of brown to 

 almost black, the great majority, however, being of
