Upperside dark vinous-brown. Male : forewing with a semi-transparent oblique 

 transverse irregular-shaped medial band, with either one or two very small oblique 

 subapical spots, and a lower spot between the upper median and radial. Female : 

 forewing with broader medial band, three subapical spots, the spot between upper 

 median and radial, and sometimes another between the upper and middle medians 

 Palpi and thorax beneath olive-brown. Antennae with a white streak near apex. 

 Underside paler : forewing with medial band and subapical spots as above, and 

 with a white costal streak above the band : hindwing fasciated transversely with 

 grey scales.

Allied to P. Alysos : forewing with similar semi-transparent medial band, 

 subapical spots, and also with a small linear spot between upper and middle median
