the Genera Leptophobia and Pieris. 17 



Pieris, Boisduval. 



This genus separates into several natural groups, the first 

 being the P. demophile group, in which the females vaguely 

 remind one of [thorn iinse (such as Sais) ; the second is the 

 P. viardi group, the females of which are often more like 

 Tiihorea, the under surface of the secondaries often richly 

 coloured in both sexes ; the third is represented by P. phileta 

 (P. monuste auct. plur., nee Linn.) and its varieties, some- 

 what short-winged Belenois-Wke butterflies ; the fourth and 

 last is represented by the P. buniai group, and unites charac- 

 teristics of Catopsilia and Ganoris, all the males exhibiting 

 well-developed patches and streaks of thickened scaling on 

 the wings, but combined with the long slender antenna? and 

 style of neuration of the later types of the Pierinae.
