  ant 
  points 
  out 
  that 
  the 
  specimens 
  agree 
  with 
  Dohrn's 
  Latin 
  descrip- 
  

   tion 
  of 
  1860 
  but 
  not 
  with 
  the 
  German 
  one 
  of 
  1863 
  (Nachtrage, 
  p. 
  49). 
  

  

  We 
  reproduce 
  Mr. 
  China's 
  sketches 
  showing 
  structural 
  details 
  of 
  

   the 
  species 
  (figs. 
  45, 
  48, 
  49). 
  The 
  color 
  of 
  the 
  forewing 
  is 
  brownish, 
  

   with 
  base, 
  a 
  band 
  across 
  basal 
  discal 
  cell, 
  and 
  the 
  apex, 
  much 
  darker. 
  

   The 
  brown 
  annulations 
  on 
  mid 
  and 
  hind 
  femora 
  and 
  tibiae 
  are 
  as 
  

   broad 
  as, 
  or 
  broader 
  than, 
  the 
  intervening 
  pale 
  spaces, 
  whereas 
  in 
  

   the 
  next 
  two 
  species 
  they 
  are 
  narrower 
  than 
  the 
  pale 
  spaces.

  We 
  have 
  not 
  seen 
  this 
  species 
  but 
  have 
  been 
  supplied 
  with 
  data 
  and 
  

   drawings 
  from 
  the 
  type 
  by 
  W. 
  E. 
  China. 
  We 
  have 
  thus 
  been 
  able 
  to 
  

   definitely 
  identify 
  the 
  species. 
  The 
  principal 
  structural 
  characters 
  

   are 
  represented 
  in 
  Figures 
  46, 
  50, 
  51, 
  52. 
  

  

  The 
  color 
  of 
  the 
  forewings 
  is 
  similar 
  to 
  that 
  of 
  marmoratus, 
  the 
  

   most 
  conspicuous 
  marking 
  being 
  the 
  rather 
  broad 
  white 
  veins 
  at 
  base 
  

   of 
  outer 
  discal 
  cell 
  which 
  form 
  an 
  angulated 
  mark 
  across 
  the 
  middle 
  

   of 
  the 
  wing; 
  the 
  base 
  of 
  costa 
  also 
  is 
  white. 
  Structurally 
  similar 
  

   to 
  marmoratus 
  except 
  as 
  stated 
  in 
  key. 
  

  

  Length, 
  20 
  mm. 
  

  

  The 
  type 
  is 
  from 
  Jamaica 
  ; 
  there 
  is 
  a 
  second 
  specimen, 
  also 
  in 
  the 
  

   British 
  Museum 
  from 
  Jamaica, 
  which, 
  according 
  to 
  Mr. 
  China, 
  

   agrees 
  with 
  the 
  type 
  in 
  all 
  characters.
