This beautiful butterfly is proverbial for the uncertainty of its 

 shewing itself. One year many will be taken in various parts of the 

 country: the next, scarce one will be seen. The proper time of its 

 first appearance is the last week in August, but sometimes it is later 

 than the preceding species. 



Clover fields, tre-foil, saint-foin, and lucerne fields, sunny grass 

 banks, and various other situations, are its resort. 



The southern districts are obviously the "locale" of this species. 



It is plentiful in Africa, in the northern parts of Asia, in Nepaul, 

 Cachemere, and other countries, and also in Europe. 



It has been captured or seen in Heslington fields near York, in 

 18 12; Winchester in Hampshire; near Dover, Birch Wood, Darenth 

 Wood, Margate, Charing, and Headley Lane, Kent: Lyme Regis, 

 Dorsetshire; Wolverton; the Isle of Wight; Lewes, both on the Downs 

 and the Ringmer Road, near Shoreham, Kemp-Town, and Brighton, 

 Arundel and Worthing, in Sussex; Matlock, Derbyshire; Eton, Buck- 

 inghamshire; Lincoln; near Cambridge, Wisbeach, but very rarely 

 indeed, and Triplow, Cambridgeshire; near Leicester; in Northamp- 

 tonshire; Broomfield, Dedham, Colchester, and Epping, in Essex; 

 Shelly, Stoke-by-Nayland, and Ipswich, Suffolk ; Belton, Norfolk ; 

 Exmouth, Devonshire; at Falmouth, in Cornwall, as W. P. Cocks, 

 Esq., has informed me; and several other localities. In Wales near 

 Llandudno. 



It is said to be double brooded, appearing in May, and in August 

 or September. — August 14th., 21st.
