'but the subterniinal line sharply white. AVith these are occa- 

 sionally specimens of a deep black-&ro/CTi colour. On the 

 hills of South Staffordshire, on the other hand, I have found 

 in June specimens having the ground-colour of the typical 

 form, but so dappled and dusted with brown as to form an 

 almost perfectly intermediate stage between it and the early 

 brown variety. In Perthshire the brown variety of the 

 South of England seems to re-appear, but of deeper colour, 

 ■and having the markings deep brown or umbreous ; and in 

 vSuffolk it has been found having the ground-colour umbreous, 

 and the markings darker umbreous and black. 



Between all the forms enumerated there exist all possible 

 intermediates ; and besides there are the second broods of 

 both races, usually smaller, and most unsatisfactory in their 

 poverty of colour and faintness of markings. 



In the collection of Mr. Sydney Webb are specimens of 

 an exquisitely pure creamy- white without brown dusting, but 

 the markings quite distinct ; also one which, having the fore 

 wings normal, is shaded with purplish-brown upon the hind ; 

 and another, having the fore wings somewhat falcate, and a 

 large round brown spot in the outer band, while the rest of 

 its markings are obscure. In that of Mr. R. C. Bradley is a 

 very white female in which the second line and its attendant 

 stripe form abroad, strongly marked band, while the other 

 markings, including the squared blotches, are quite indistinct 

 — a striking and unusual aberration. One taken at Clevedon, 

 Somerset, has the first line placed close to the base, and the 

 second near the hind margin, and strongly marked, the 

 middle portion of the wings forming a most remarkably broad 

 white band. In Mr. S. J. Capper's collection two specimens, 

 grey in colour, but not very dark, and showing the markings 

 fairly well, have each of them a portion of one hind wing of 

 the normal creamy-white colour, the division between the 

 two colours being sharp, and running longitudinally down 

 the wing, so as nearly to divide it in halves. Finally, the
