S 2 • Closely resembles P. lisarda, but on the upperside the 

 ground-colour is darker, the streaks and 

 spots very much narrower and smaller, 

 and those on the fore wing conspicuously 

 suffused with blue. Fore wing : the streak 

 at base of cell broken, forming two elon- 

 gate narrow spots, the spot in interspace 4 

 of the postdiscal series conspicuously out 

 of line with the rest. Hind wing : the 

 white in the discoidal cell reduced to two 

 short streaks. On both fore and hind 

 wings the spots of the subterminal series 

 more or less hastate in shape with 

 the points directed inwards. Underside : 

 ground-colour as in P. lisarda, the streaks 

 and spots of white as on the upperside 

 hut broader and somewhat larger; those 

 on the fore wing more decidedly suffused 

 with blue. Antennae, head, thorax and 



abdomen as in P. lisarda but darker ; beneath, the abdomen white 



along the sides.
