was found now and then, probably every year. Somewhere 

 in the hilly districts of Staffordshire there was a form having 

 the central markings very grossly scaled, and therefore it 

 somewhat approached the Scotch form referred to. 



Mr. J. Jenner Weir, referring to the disappearance of this 

 species from many well-known localities where it once 

 occurred freely, doubted whether it c^uld be attributed to 

 over-collecting. Mr. Tugwell said that an old locality near 

 Sandwich was occasionally entirely inundated with water ; 

 and this, together with the over-collecting that had taken 

 place, would easily account for its disappearance. Mr. Tutt 

 said it could not be over-collecting which had caused the 

 disappearance of M, athalia from Chattenden ; and, as 

 regards the effect of floods and tides, he instanced the case of 

 Agdistis beniietii. Curt., which came up as fresh as ever on 

 the tide going down. 



Mr. Tugwell stated that during the week he had a run 

 down to Tilgate Forest, and was surprised to find Argynnis 

 euphrosyne^ L., flying in some numbers, and he obtained a 

 very pretty variety. He had also taken some nice forms of 

 Syrichthus malvcs, L., and Nisoniades tages, L. He had only 

 taken some six or seven larvae of Sesia sphegifonnis, Fb., as 

 the ground appeared to have been already thoroughly worked. 

 The spring flowers were not so forward as the lepidoptera 

 by a fortnight or three weeks. Mr. Tugwell also referred to 

 the disappearance of the nightingale from Tilgate during the 

 last two or three years. 



Mr. J. A. Cooper referring to Mr. Bouttell having, on one 

 occasion, captured several specimens of TcBniocampa opima, 

 Hb., on Wanstead Flats, Essex, now reported that he had 

 taken nests of larvae, and seen many others, which were un- 

 doubtedly referable to this species.

Mr. Jenner Weir exhibited a specimen of Anosia plexippus, 

 L., var. erippus, Cramer, which had been obtained by one of 

 the employes of Captain Parke in the Falkland Islands : until 

 this insect was captured the only butterfly known in those 

 islands was Brenthis cytheris, Drury. During Captain 

 Parke's residence in these islands for about twenty years 

 he had never seen a specimen of the Anosia in ques-
