234 Mr. H. T. Stainton's Notes on the 



from 1,500 to 2,000 feet above the level of the sea. In Scotland 

 it occurs on Ben Lomond and on some of the Perthshire moun- 

 tains. In Ireland it occurs in Galvvay and Donegal. 



It is remarkable that neither of the last two species have yet 

 been observed in Wales. 



We now come to consider the range of our seven local species, 

 Papilio Machaon, Melitcea Cinxia, Thecla Pruni, Pohjommalus 

 Arion, P. Acis, Steropes Paniscus, Pamphila Actceon, thus, — 



Papilio Machaon occurs in the fens near Cambridge and near 

 Norwich, but we know of no other defined localities for 

 this noble insect, though a few specimens have occurred at 

 Pulborough, in Sussex, and at Heme Bay, in Kent. 

 Melitcea Cinxia is abundant at Sandown, in the Isle of Wight, 

 and is not scarce at Folkestone ; a few specimens have 

 occurred near Stowmarket and Peterborough. 

 Thecla Pruni — for this we only know one locality, Monk's 



Wood, in Huntingdonshire. 



Polyommatus y^rion. .Barnwell Wold, Northamptonshire; 



Chatteris, Cambridgeshire; Rington, 



in Rutlandshire ; Cheltenham, and in 



South Devon. 



Polyommatus Acis ..Lewes, Lower Guiting, formerly at 



Leominster. 

 Steropes Paniscus. . . . Bourne, Lincolnshire ; Monk's Wood, 



Hunts, and near Oxford. 

 Pamphila Actceon. .. .IjuUvoYth, Dorsetshire; said to occur 

 also at Sidmouih, in Devon. 



The circumstances which cause the restriction of a few species 

 to such very confined localities is at present unknown to us. They 

 are not so restricted on the Continent. P. Machaon and P. Acis 

 are universally distributed in Germany, and, with the single ex- 

 ception of Pamphila Actceon, all the others are very generally dis- 

 tributed in Germany, though not occurring in every district. 



Of the three stragglers in this country — Pieris DapUdice, Ar- 

 gynnis Lathonia and Vanessa Antiopa — the two former seem 

 confined to the southern counties of England, not ranging north 

 of Peterborough, but F. Antiopa is most plentiful between the 

 Humber and the Tyne, and has more than once been noticed on 

 the north side of the border. 



Of the two species which may be considered extinct with us, 

 one (Chrysophanus Dispar) used to be abundant at Whittlesea 

 Mere, but since that was drained, causing cornfields to wave where 

 reeds had formerly held undisputed sway, the insect has dis-
