ledge of their earlier stages, Many that are rare in the perfect 

 state are comparatively easy to find as larvae. Most of them 

 feed on flowers or seeds, often quite exposed, and require very 

 little attention to bring them to maturity. It will be found 

 that some, very closely allied as imagines, are very distinct as 

 larvae ; while others, very similar as larvae, are widely different 

 as perfect insects.

This very pretty and distinct species has been seldom taken 

 in our district. It is, no doubt, an insect of very retiring 

 habits, but I see no cause for its apparent scarcity here, and 

 expect it will be found much commoner than appears at present. 

 Mr. D. Rosie took a single specimen at Stocksfield. Darlington 

 is a '' Manual" locality, but I do not know on what authority. 

 Mr. Gardner and I have taken single specimens at Hartlepool, 

 on the railway side behind the Eopery, and elsewhere, where 

 there was an abundance of Silene injiata^ but we never found 

 the larva, and I do not think the species is established about 

 Hartlepool. The last I took was in 1893. 



'{E. extensaria. A rumour reached me that this insect had 

 been reared from larvae found on the Durham coast. I have 

 fully investigated the matter, and find that the definite state- 

 ment made to me was not correct. When news of the discovery 

 of this species at Spurn Point, Yorkshire, was first published, 

 Mr. Gardner and I thought the extensive salt marshes at the 

 mouth of the River Tees was a place where the species was 

 likely to occur. A. search there did not produce it, but 

 in Entomology non-discovery is by no means proof of non- 

 existence, and I still think the locality so suitable (and there
