PIIYLLOCIIARIS, ICJI 



from that genus in various ^trjctural characters, as well as 

 in the want of any " orange t p " to the fore-wings ; con- 

 sequently both sexes resemble females of Euchloe. They 

 are while above, with similar markings, and on the under 

 surface they are green, sometimes varied with yellow, and 

 with silvery-white markings. The sub-costal nervure of 

 the fore-wings is five-branched, only the first branch being 

 thrown off before the end of the cell, and the second 

 at or beyond the end of the latter. The first radial nervule 

 only separates from the sub-costal at about one-third of its 

 length, and the middle disco-cellular nervule is either very short 

 or wanting, whereas it is well marked in Euchloe. On the hind- 

 wings the lower radial is almost straight. The type is Phyl- 

 locharis tagis (Hiibner), a small species, not measuring more 

 than about an inch and a quarter across the wings. It is white 

 above, with the tip of the fore-wings black, spotted with white, 

 and a black streak at the end of the cell, narrower than in the 

 allied species, in which it more resembles Pontia daplidice. 

 The under side is green, or greeaish-yellow, with white, rarely 

 silvery, spots. 



The larva is green, pubescent, with a white lateral band, bor- 

 dered above with a red one. The pupa is pale flesh-colour, 

 darker at the hinder end. The ends are pointed, but it is 

 more blender than the pupa of Euchloe. 



The Butterfly is found in Southern France, Spain, and 

 Portugal, Corsica, and Sardinia, and in each country it ex- 

 hibits slight local variations. 



There is a small genus, Zegris, Rambur, confined to the ex- 

 treme South of Europe, and Western Asia, in which the orange 

 in the apical area is reduced to a long oval patch, surrounded 

 with black, and with the tip of the wing pale greenish. The
