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 Ithomiinas (such as Sais) ] the second is the 

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

 Tithorea, the under surface of the secondaries often richly 

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

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

 what short- winged Behnois-\\kQ, butterflies ; the fourth and 

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

 teristics of Catopsilia and Ganoria^ all the males exhibiting 

 well-developed patches and streaks of thickened selling o;i 

 the wings, but combined with the long slender antenucS and 

 style of neuration of the later types of the Pierina3.
