While Biitierjiies of Britain, 



7. The middle green- 

 veined white butterfly 

 (Pontiff sabellicae Peti- 

 mr) {Jig, 60.) is larger 

 than P. ;2api, but smaller 

 than the preceding. The 

 wings also are shorter 

 and more rounded than 

 in P. wapi, and the veins 

 are dark above, and un- 

 derneath are not green- 

 ish, but dusky and very 

 broad. This insect agrees, 

 according to Mr. Stephens, with P. iryonias of Wallner. It is 

 not easy to distinguish it from the preceding. 



II. — Fore wings with the tip rounded; under wings variegated 



beneath. 



8. The Bath white butterfly 

 (Pontiff daplidice) {fig,Ql,) is 

 one of our rarest British in- 

 sects; not above five or six 

 having been hitherto caught in 

 ithis country. It is about the 

 ^^C^Qsize of P. Napae^as ; the ground 

 colour of the wings white, with 

 the tips of the fore wings black 

 spotted with white, and the 

 under surface of the hinder 

 wings yellowish green, with 



white spots and an angular transverse line. 

 9. The orange-tip 



butterfly (Pontiff carda- 



mines) ( fig, 62.), or 



Wood-lady of the Lon- 

 don fly-fanciers, is one 



of our prettiest British 



insects, and is common 



all over the country. 



The beautiful shade of 



orange on the angle of 



the fore wing [a a a a) 



will readily distinguish 



the male from every 



other butterfly ; but as the female has no orange mark, it may 



be necessary to look at the under side of the hinder wings, 



the fine marbling of which cannot be mistaken.
