  Male. 
  Upperside. 
  Both 
  wings 
  dull 
  purple. 
  Underside 
  closely 
  resembles 
  

   D. 
  Pulchra, 
  Giier, 
  but 
  differs 
  as 
  follows 
  : 
  — 
  On 
  the 
  anterior 
  wings 
  the 
  pale 
  

   submarginal 
  band 
  which 
  crosses 
  the 
  wings 
  is 
  interrupted 
  on 
  its 
  upper 
  half, 
  

   and 
  forms 
  a 
  sagittate 
  band, 
  the 
  middle 
  part 
  of 
  which 
  extends 
  inwardly 
  towards 
  

   the 
  end 
  of 
  the 
  cell 
  ; 
  the 
  pale 
  spot 
  near 
  the 
  end 
  of 
  the 
  cell 
  is 
  broader 
  and 
  less 
  

   elongate, 
  the 
  white 
  basal 
  streak 
  along 
  the 
  upper 
  part 
  of 
  the 
  cell 
  is 
  shorter, 
  and 
  

   the 
  white 
  streak 
  below 
  the 
  median 
  nervure 
  of 
  D. 
  I'ukhra 
  is 
  absent 
  ; 
  the 
  ground- 
  

   colour 
  is 
  not 
  shaded 
  with 
  paler 
  brown 
  towards 
  the 
  base 
  and 
  inner 
  margin. 
  

   On 
  the 
  posterior 
  wings 
  the 
  ground-colour 
  is 
  brighter 
  chestnut-brown, 
  and 
  the 
  

   markings 
  are 
  more 
  tawny 
  ; 
  the 
  pale 
  tawny 
  band 
  beyond 
  the 
  cell 
  is 
  broken 
  on 
  

   the 
  subcostal 
  nervule. 
  

  

  Female. 
  The 
  upperside 
  scarcely 
  differs 
  from 
  the 
  same 
  sex 
  of 
  D. 
  Pulchra, 
  

   and 
  on 
  the 
  underside 
  it 
  is 
  identical.

  The 
  male 
  is

  of 
  Mr. 
  Grose-Smith

  Walter

   and 
  the 
  female 
  in 
  the 
  Collection 
  of 
  the 
  latter. 
  

  

  The 
  principal 
  difference 
  between 
  this 
  species 
  and 
  D. 
  Pulchra 
  is 
  the 
  absence 
  in 
  the 
  male 
  of 
  

   D. 
  Diantha 
  of 
  the 
  oblique 
  blue 
  band 
  on 
  the 
  upperside 
  of 
  the 
  anterior 
  wings 
  of 
  the 
  same 
  sex
