not been favourable to its permanent establishment, and that 

 it has gradually become extinct, 



" Aporia crat(Zgi has disappeared almost entirely from the 

 New Forest, where I have taken it myself, and where it was 

 at one time very abundant. It first became rare in the eastern 

 parts of the Forest ; it probably still lingers in the western 

 parts, where I have taken it of late years ; but in 1886 I 

 could not hear that one had been seen. 



" Leucophasia sinapis. — Mr. Jenner's note of this species is, 



* Very scarce, and apparently extinct in many localities where 

 formerly found.' This is quite in accordance with my own 

 experience ; it used to be taken by my uncle near Lewes in 

 1834, where it is now extinct ; and although I often visit 

 Abbot's Wood, and have done so for years past, I never 

 found it there. This appears to me to be a case of an in- 

 digenous insect becoming extinct in certain parts of Sussex, 

 which, from the weakness of its flight, was not likely to have 

 flown over from the Continent, as might have been the case 

 with A. cratcBgi, a gregarious insect, which L. sinapis is not. 



"Melitcsa aurinia. — Of this species Mr. Jenner's note is, 



* Local and rare, Chailey and Ringmer.' I have sought in 

 vain for this insect in Sussex; it was at one time very abun- 

 dant at Chailey, the home of my ancestors. I recollect that 

 some school-children brought over to Mr, Auckland from 

 Chailey a clothes-basket covered with pinned specimens of 

 M. aurinia; there were about 400. Mr, Auckland's note is 

 as follows : ' Abounded at Chailey from 8th May to June, 

 1834 ; I had sent me many hundreds,' 



^'Vanessa c-album. — Mr, Jenner notes it as 'Very rare; 

 once at Southover, Lewes ; Guestling, rare ; Tilgate,' I have 

 never taken this species in Sussex ; but in the hop-gardens it 

 was once common — so much so, that the peasants had a local 

 name for it, viz., the * silver bug.' An aged relation of mine 

 has often described the species to me as being very well 

 known ; but, although he made every endeavour between 

 thirty or forty years ago to obtain the larva for me, he found 

 it was extinct. He himself, a grower of hops, was very 

 observant, and his testimony is therefore of value.
