REPUTED BRITISH SPECIES. 171 



PARNASSIUS APOLLO. The APOLLO Butterfly (fig. 

 2). I have good reason for believing that a specimen 

 of this splendid Alpine butterfly was captured in this 

 country very lately, and it is not at all impossible that 

 it may be some day found on our north country moun- 

 tains, or those of the Lake District. It is a most 

 beautiful insect, with its singular semi-transparent and 

 partially glazed wings ; the lower of which bear large 

 eye-spots of crimson-scarlet. 



EREBIA LIGEA. The AEEAN BEOWN Butterfly 

 (fig. 3). Of this species, greatly resembling our E. 

 Blandina, several specimens were formerly taken by 

 some entomologists in the Isle of Arran, where, as also 

 in other mountain districts, it may probably still exist ; 

 but its haunts have to be re-discovered by some enter- 

 prising butterfly-hunter.

 the upper surface, it may be distinguished by the mark-

 irregular, broken band of pure white, and between this 

 and the margin a row of three distinct black eye-spots.

 the upper surface, that it readily might be, and perhaps
