  The 
  follo\ving 
  table 
  will 
  separate 
  the 
  five 
  species 
  of 
  Farigia 
  known 
  

   to 
  occur 
  in 
  Mexico: 
  

  

  Sexes 
  dimorphic; 
  antennae 
  of 
  female 
  bipectinate; 
  male 
  with 
  raised 
  whitish 
  discal 
  

  

  mark 
  montana 
  Druce. 
  

  

  Sexes 
  monomorphic; 
  antennae 
  of 
  female 
  simple; 
  male 
  with 
  discal 
  mark, 
  if 
  present, 
  

   dark. 
  

   A 
  black 
  shade 
  from 
  base 
  of 
  fore 
  wing 
  below 
  cell 
  bordering 
  the 
  eubterminal 
  line, 
  

  

  hydriana 
  Schaus. 
  

   Black 
  shade 
  over 
  median 
  space 
  in 
  lower 
  half 
  of 
  cell 
  to 
  inner 
  margin, 
  not 
  crossing 
  

  

  outer 
  line 
  magniplaga 
  Schaus. 
  

  

  No 
  broad 
  black 
  shades. 
  

  

  Outer 
  line, 
  inner 
  half 
  of 
  median 
  space 
  and 
  submedian 
  streak 
  narrowly 
  black 
  

  

  shaded 
  malomen 
  Dyar. 
  

  

  No 
  black 
  linings 
  except 
  the 
  ordinary 
  markings 
  vecina 
  Schaus. 
  

  

  It 
  seems 
  possible 
  that 
  the 
  four 
  forms 
  hydriana, 
  magniplaga, 
  malomen, 
  

   and 
  vecina 
  may 
  prove 
  to 
  belong 
  to 
  one 
  variable 
  species 
  since 
  they 
  

   differ 
  only 
  in 
  the 
  black 
  shadings 
  and 
  not 
  in 
  pattern.
