together either earth or leaves with a few threads, and is 

 slender in form, the tip of the tail ending very bluntly with 

 three little horny warts ; the colour reddish-brown, the edges 

 of the wing-cases brighter. 



The food supplied was Pohjgojimn avicularej and seemed 

 to suit very well. 



It appears that the larvae of J.«V/rtZ/(^, if they can meet 

 w^ith sufficient heat, and a supply of fresh tender food at the 

 same time, will feed up so rapidly as to produce a second brood 

 of moths in August or September ; thus, this season I know 

 A. ornata, mancuniata^ and the species I have just described, 

 have been partially double-brooded ; but I am inclined to 

 think that with most of the species the greater number of 

 the larvse hvbernate. 



Since the foregoing pages were written we have thought 

 it desirable to add the following brief notes on 



TWO NEW BRITISH TORTRICES : — 



Sericoris rupestrana, Duponchel. 



This species, which is, I am informed, common on the 

 moors in the north of England, has hitherto been considered 

 in this country as a variety of Sericoris lacunana. It is, 

 however, considerably smaller than that species, and may be 

 distinguished from it by the absence of metallic dots on the 

 anterior wings, and also by the central fascia being paler. 

 The head and palpi as well as the thorax and abdomen are 

 blackish. When seen in series, it has an appearance very 

 distinct from that of S. lacunana^ though an odd specimen 

 might easily pass for a small variety of it. 



The insect has recently been added to our lists in the sup- 

 plement to Mr. Doubleday's Catalogue, and will henceforth 

 occupy a separate space in our cabinets.
