  This 
  species 
  differs 
  but 
  little 
  from 
  the 
  South 
  American 
  

   Copocercia 
  cramhinella, 
  Z., 
  except 
  in 
  the 
  arrangement 
  of 
  

   the 
  costal 
  streaks, 
  and 
  in 
  the 
  more 
  consj)icuous 
  third 
  

   line 
  of 
  white 
  crossing 
  the 
  fold. 
  Polyhymno 
  luteotactella, 
  

   Chamb., 
  is 
  very 
  similar, 
  but 
  distinct.

  a 
  slender 
  line 
  in 
  the

  of 
  the

   before 
  which 
  it 
  meets 
  the 
  scarcely 
  less 
  oblique

  much 
  shorter 
  

   costal 
  streak, 
  which 
  commences 
  at 
  about 
  one-third

  the 
  costal 
  streak
