  similar, 
  but 
  the 
  colour 
  of 
  the 
  wing 
  is 
  of 
  a 
  different 
  

   character, 
  and 
  the 
  marginal 
  band 
  of 
  the 
  hind 
  wings 
  

   above 
  and 
  below 
  is 
  quite 
  different, 
  and 
  about 
  half 
  the 
  

   width 
  of 
  that 
  species.

  Fore

  marks

  the

  transverse 
  out- 
  

   wardly 
  curved 
  line 
  at 
  the

  Both 
  wings 
  with 
  a 
  discal 
  

   grey 
  line 
  nearly 
  corresponding 
  to 
  the 
  shape 
  of 
  the 
  outer 
  margins, 
  

   with 
  small 
  dentations 
  outwards 
  on 
  the 
  veins 
  ; 
  there 
  is 
  a 
  very 
  

   slight 
  ochreous 
  grey 
  tinge 
  on 
  the 
  fore 
  part 
  of 
  the 
  thorax

  the 
  exception 
  of 
  the 
  discal 
  line 
  being 
  slightly 
  visible 
  through 
  

   the

  a 
  slight 
  brown 
  suffusion

  The 
  discal 
  line 
  runs 
  up 
  to 
  the 
  costa 
  in 
  an 
  even 
  curve, 
  

   somewhat 
  as 
  in 
  P. 
  rufofasciata, 
  Moore, 
  but 
  is 
  nearer 
  to 
  

   the 
  outer 
  margin 
  ; 
  its 
  white 
  unmarked 
  surface, 
  however, 
  

   distinguishes 
  it 
  from 
  all 
  the 
  other 
  Indian 
  species 
  of 
  this 
  

   genus.
