If the imagination chooses so to please itself, it may look upon our 

 own country as a sort of epitome of the northern hemisphere of the 

 world, as to its natural productions, and thus we shall find that on 

 the south coast, from Torquay to Hastings are our tropics; in the 

 midland counties our temperate zone; in Scotland our Arctic regions; 

 and John o'Groat's House will answer to the North Pole. Corres- 

 pondingly hereto are our Butterflies localized. Excepting in the case 

 of some chance wanderer, driven by we know not what storm, or 

 tempest, or, " favouring gale," the races are, for the most part, distinct, 

 and those which flourish in the one district, woukl perish at once in 

 the other, through the difference of climate. 



This is a most beautifully-coloured butterfly, whether seen on the 

 wing, in its zigzag, impetuous, and hurried flight, or examined at 

 leisure in the cabinet. In the latter case you seem never to be able 

 to get it in a sufficiently good light, so full and bright are its colours, 

 to admire it as it ought to be admired, and when first emerged from 

 the chrysalis, and glittering before you in the sun, it is indeed a most 

 attractive object. 



In Yorkshire, and as far north as Newcastle in Northumberland, 

 and the lake district in Westmoreland, it occurs, but not by any 

 means so plentifully as in the more southern parts of the country. 

 It is very rare iu the neighbourhood of Falmouth: W. P. Cocks, Esq. 

 has, however, taken it there in 1845, and also in 1850. In Scotland 

 it appears to be unknown.
