44 [July, 



Ilercm^ialis perennis (dog's mercury) drawing together tlie tips of the 

 leaves in April. It fed up on this plant, and spun up among rubbish, 

 the moth emerging early in July. 



This species is rare — or absent — in Pembrokeshire, but from know- 

 ledge of it in other districts, I have no doubt it is extremely poly- 

 phagous. I have known it to feed freely on yew. 



Garpocapsa Juliana, Curt. — Larva sluggish, cylindrical, rather 

 plump and wrinkled. Whitish in colour, and having a crossbar of 

 pale brown on the back of the 4th to the 12th segments. Spots 

 prominent, shining, dark red, with minute hairs. Head pale brown, 

 dorsal-plate whitish, with a necklace of black markings forming a large 

 crescent round its posterior edge. Anal-plate black in front, shaded 

 off behind. 



Found feeding in the fruit of the edible chestnut in Grreenwich 

 Park, by Mr. W. West, and reared by him. I failed to rear those he 

 sent to me. 



Stigmonota nlfidana,Ysih. (redimitana, Gn.). — Young larva cylin- 

 drical, not active, semi-transparent, dirty white, spots black, large and; 

 very distinct, dorsal vessel dark grey and very visible, and with thej 

 assistance of the black dots forming a zigzag, or chain-like, series oi; 

 markings along the dorsal region. Head, plates, and feet jet-black. 



When full-grown, active, slender, cylindrical, with rather wrinkled* 

 segments, semi-transparent, pale yellow with the dorsal vessel grey oii: 

 greenish. Hairs rather long. Head and plates bright yellow. Anal 

 legs rather extended. 



On oak, generally on low boughs, or oak bushes under the trees i 

 Living between two leaves, the surfaces of which it joins together jvitl 

 silk, and making a tubular habitation of silk between them with a good 

 deal of loose web. Gnawing the inner surfaces of both leaves, and 

 so blotching them extensively. Moving readily to a fresh pair ot 

 leaves which it joins in the same way. AVhen full fed, forming a small 

 tough egg-shaped cocoon covered with frass, between the leaves, but 

 not in the silken tube. Feeding from June to September ; passing the 

 winter in the cocoon attached to the leaves, where it turns to a paid 

 olive-brown pupa, which is forced partly out of the cocoon when the 

 moth emerges in the succeeding May or June. 



I found many larvse in Canaston wood, and Dr. Wood sent mc 

 others from Ledbury. , 



Stigmonota Weirana, Dougl. — Larva rather flattened, with deep^;
