170 BRITISH BUTTERFLIES. 



EEPUTED BEITISH SPECIES. 



ON Plate XYI. are grouped together figures of six 

 species of butterflies which are not admitted into our 

 regular British lists, on account of the extreme rarity of 

 their capture, or the fact of their not having been 

 observed at all for several years past. They are all 

 common species in various parts of the Continent, and 

 some of them will probably occur again in this country. 



PAPILIO PODALIRIUS. The SCAECE SWALLOW- 

 TAILED Butterfly (fig. 1). There is no reasonable 

 doubt that several individuals of this elegant butterfly 

 were formerly taken in various parts of the country, but 

 no captures have occurred for many years past. The 

 caterpillar, also, was more than once found in the New 

 Forest District, Hampshire. Generally a common insect 

 on the Continent.
