  NOTES 
  ON 
  CATOCALA 
  PRETIOSA 
  LINTO. 
  

  

  This 
  species 
  is 
  closely 
  allied 
  to 
  G. 
  polygama 
  Guen. 
  Its 
  

   distinctive 
  features 
  may 
  he 
  more 
  clearly 
  appreciated 
  by 
  a 
  

   differential 
  comparison 
  with 
  that 
  species. 
  The 
  basal 
  region 
  is 
  

   conspicuously 
  and 
  broadly 
  shaded 
  with 
  black, 
  deepening 
  

   toward 
  the 
  anterior 
  transverse 
  line 
  ; 
  in 
  polygama, 
  shaded 
  with 
  

   ferruginous. 
  The 
  anterior 
  transverse 
  line 
  is 
  geminate, 
  mod- 
  

   erately 
  oblique 
  in 
  Lfcs 
  general 
  direction, 
  tending 
  to 
  the 
  posterior 
  

   •third 
  of 
  the 
  internal 
  margin, 
  distinctly 
  separated 
  by 
  white 
  

   below 
  and 
  slightly 
  above 
  the 
  sub 
  median 
  : 
  in 
  polygama 
  the 
  

   line 
  is 
  quite 
  oblique, 
  tending 
  to, 
  or 
  very 
  near 
  to, 
  the 
  internal 
  

   angle, 
  and 
  is 
  preceded 
  below 
  the 
  submedian 
  by 
  gray 
  and 
  fer- 
  

   ruginous 
  scales. 
  

  

  The 
  posterior 
  transverse 
  line 
  has 
  the 
  extra- 
  cellular 
  teeth 
  

   moderate, 
  unequal, 
  the 
  lower 
  one 
  in 
  cell 
  4 
  being 
  improminent 
  ; 
  

   moderately 
  angulated 
  outwardly 
  (not 
  toothed) 
  on 
  the 
  sub- 
  

   median 
  fold 
  before 
  the 
  sinus; 
  the 
  sinus 
  short, 
  not 
  extending 
  

   to 
  the 
  middle 
  of 
  the 
  wing, 
  the 
  line 
  narrow 
  with 
  ferruginous 
  

   and 
  white 
  below 
  it; 
  from 
  the 
  sinus, 
  running 
  direct 
  and 
  slightly 
  

   oblique 
  outwardly 
  to 
  the 
  internal 
  margin, 
  followed 
  by 
  a 
  white 
  

   line. 
  In 
  polygama 
  the 
  two 
  teeth 
  are 
  conspicuous 
  and 
  nearly 
  

   equal 
  ; 
  sharply 
  toothed 
  outwardly 
  on 
  the 
  submedian 
  fold, 
  as 
  

   in 
  C. 
  cratcegi; 
  sinus 
  long, 
  reaching 
  the 
  middle 
  of 
  the 
  wing, 
  the 
  

   line 
  broad, 
  with 
  ferruginous 
  on 
  each 
  side 
  and 
  without 
  white 
  

   below 
  ; 
  below 
  the 
  sinus, 
  a 
  long 
  and 
  sharp 
  tooth 
  bordering 
  the 
  

   internal 
  margin. 
  

  

  The 
  two 
  transverse 
  lines 
  are 
  separated 
  on 
  the 
  submedian 
  

   nervure 
  by 
  a 
  space 
  equal 
  to 
  the 
  width 
  of 
  cell 
  2 
  on 
  the 
  ter- 
  

   minal 
  margin, 
  whence 
  they 
  run 
  parallel 
  to 
  the 
  internal 
  

   margin 
  ; 
  in 
  polygama, 
  they 
  are 
  nearly 
  or 
  entirely 
  united 
  on 
  

   the 
  submedian, 
  beyond 
  which 
  they 
  widely 
  diverge 
  and 
  again 
  

   wholly 
  or 
  nearly 
  unite 
  on 
  the 
  internal 
  margin. 
  

  

  The 
  reniform 
  is 
  broadly 
  surrounded 
  by 
  white 
  ; 
  in 
  polygama 
  

   narrowly. 
  The 
  subreniform 
  is 
  round, 
  its 
  outline 
  denned 
  by 
  

   black 
  scales 
  ; 
  it 
  touches 
  outwardly 
  the 
  median 
  shade-line 
  on 
  

   vein 
  2 
  ; 
  of 
  the 
  two 
  transverse 
  lines, 
  it 
  is 
  nearer 
  to 
  the 
  posterior,
