the Genera Leptophobia and Pieris. 1.7 



PlKiUS, Boisduval. 



This genus separates into several natural groups, the first 

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

 remind one of Ithomiinse (such as S-n's) the second is (he 

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

 Tithoreaj the under surface of the secondaries often riehly 

 coloured in both sexes; the third is represented by P. /t'ti/etd 

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

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

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

 teristics of Catopsilia and G-anorix, all the males exhibiting 

 well-developed patches and streaks of thiekiiiel soiling on 

 the wings, but combined with the long slen ler antennie and 

 style of neuration of the later types of the Pierirue.
