AGR0TERA NEMORALIS. 57 



The young larvae batch in about ten days, and at 

 first feed on the under-side of the leaves, beneath a 

 loosely-spun web. After the second moult they 

 gnaw little round holes in the leaf, just large enough 

 for them to crawl through on their feeding excursions, 

 and through which they re-enter their little silken 

 abodes for rest and shelter. If touched or irritated, 

 they crawl very quietly either backwards or forwards, 

 Tortrix-like. 



When full-grown they are about nine-tenths of an 

 inch long, of a pale yellowish-green colour, the head 

 being of a slightly warmer tint of ochreous, and shiny ; 

 a few colourless hairs are sparsely dispersed over the 

 body, mostly along the spiracles. 



The larva spins up on a leaf by neatly and com- 

 pactly folding up a portion of it, in shape something 

 like a " turnover tart ; " this it lines with silk, making 

 it doubtless a secure and water-tight abode to pass 

 the winter, when of course it is detached from the tree 

 — a sport to the winds. 



The imago appears about the 20th of May follow- 

 ing. (W. H. Tugwell, July, 1876; Entom., August, 

 1876, IX, 179.)

While engaged in studying Endotricha flammealis 

 from the egg to the perfect insect, it has been my 

 good fortune again to be associated in the deeply 

 interesting task with Mr. William K. Jeffrey, who not 

 only at the beginning supplied me with ova, but 

 subsequently with the most favoured and promising 

 of his larvaa, on occasions, and at a very critical period 

 when failure seemed almost inevitable, and for his 

 kind and invaluable assistance my grateful thanks are 

 here recorded. 



I received the eggs on the 28th of July, 1881, about
