  with 
  a 
  smoky 
  cloud 
  ; 
  at 
  the 
  base 
  of 
  the 
  stigma 
  is 
  an 
  

   oblique, 
  deep 
  black 
  cloud, 
  which 
  extends 
  from 
  the 
  costa 
  

   to 
  the 
  recurrent 
  nervure, 
  it 
  having 
  near 
  the 
  apex 
  a 
  round, 
  

   paler 
  space 
  ; 
  and 
  it

  continued 
  to 
  the

   as 
  a 
  narrow 
  cloud, 
  originating 
  from

  base. 
  The 
  hinder 
  

   wings

  a 
  sharp 
  keel,

  few 
  smaller 
  irregular 
  striations,

   elongated 
  reticulations.

  the 
  

   second 
  segment 
  large, 
  somewhat 
  triangular 
  and 
  deep 
  ;

  segment 
  is 
  stoutly 
  striated, 
  except 
  at 
  the 
  apex, 
  where 
  

   it 
  is 
  smooth 
  ; 
  at 
  the 
  base 
  are 
  three 
  smooth 
  spaces 
  ; 
  the 
  

   central 
  is 
  the 
  largest, 
  and 
  is 
  narrowed 
  at 
  the 
  top; 
  the
