"Vanessa polychloros. — Mr. Jenner says, 'Local and less 

 common than formerly/ I have scarcely seen this insect in 

 Sussex for thirty years ; it was at one time common near 

 Lewes, and my series was taken at Keymer. 



"Melanargia galatea. — Mr. Jenner says, ' Local, near 

 Lewes (formerly) ; Firle Beacon.' This is another singular 

 case of the disappearance of a Lepidopteron once common 

 near Lewes. At one time it appeared year after year at 

 Oxsettle, near Lewes ; I have not seen it there for over forty 

 years. Mr. Auckland notes that this species was taken by 

 him at Plashet Wood, Chailey, and Warningore Wood, in the 

 beginning of June. 



"Pararge egeria. — ' Woods and shady lanes ; not common, 

 but generally distributed ' (Jenner). This species is yearly 

 becoming rarer. Mr. Stanton Hillman, of Lewes, informs 

 me that he has not seen one for years. In my younger days 

 it was common. 



"Lyccena czgon. — ' Local ; Brighton, Hay ward's Heath, 

 Lewes, Chailey, Tilgate Forest ' (Jenner). This insect was 

 common at one time on Cliffe Hill, Lewes. I find in my notes 

 that on June 8th, 1844, I took 15. Mr. Auckland notes it as 

 found there during the months of July and August. It has 

 now quite disappeared from that locality ; I have not seen it 

 there for at least forty years. 



" With this I conclude my notes. As to the causes of the 

 progressive rarity of the seven latter species mentioned I 

 cannot hazard even a conjecture; but I feel tolerably certain 

 that it has not been brought about by the entomologists, 

 although in some instances man may be the cause, owing to 

 the cultivation of the soil and the eradication of the food- 

 plant of the species." 



Mr. South said that, as Mr. Weir pointed out, Aporia 

 cratcegi very probably migrated here, occurred for several 

 years, and then gradually disappeared. Mr. Tugwell said 

 that he first saw A. cratcegi alive some years since at Heme, 

 a village near Heme Bay. His attention was attracted by a 

 large white butterfly in an uncut grass field, and on entering
