  The 
  spots 
  " 
  beyond 
  the 
  median 
  nerve 
  ' 
  ' 
  vary 
  in 
  size 
  and 
  in 
  

   number 
  in 
  the 
  same 
  species, 
  as 
  will 
  readily 
  be 
  seen 
  by 
  an 
  

   inspection 
  of 
  a 
  number 
  of 
  individuals. 
  In 
  two 
  of 
  the 
  above 
  

   examples 
  of 
  JV. 
  tristis, 
  there 
  is 
  a 
  white 
  spot 
  in 
  each 
  of 
  the 
  

   cells 
  2 
  and 
  3 
  ; 
  in 
  the 
  third,, 
  in 
  cell 
  3 
  only. 
  When 
  but 
  one 
  spot 
  

   is 
  present, 
  it 
  is 
  always 
  that 
  in 
  cell 
  3, 
  — 
  the 
  smaller 
  of 
  the 
  

   two 
  having 
  disappeared. 
  Nor 
  does 
  the 
  number 
  of 
  anteapical 
  

   white 
  spots 
  afford 
  a 
  specific 
  character, 
  for 
  while 
  the 
  normal 
  

   number 
  is 
  four, 
  some 
  examples 
  of 
  iV. 
  Martialis 
  in 
  my 
  collec- 
  

   tion 
  show 
  but 
  three, 
  and 
  others 
  (more 
  rarely) 
  five.

  Thorax 
  and 
  abdomen 
  above, 
  black 
  ; 
  beneath, 
  with 
  brown 
  

   hairs. 
  Palpi 
  clothed 
  with 
  long 
  brown 
  hairs. 
  Legs 
  fuscous. 
  

  

  Primaries 
  with 
  the 
  costal 
  margin 
  nearly 
  as 
  straight 
  as 
  in 
  

   i\T. 
  Persius, 
  but 
  rounded 
  toward 
  the 
  apex 
  ; 
  moderately 
  bent 
  

   basally. 
  Outer 
  margin 
  more 
  rounded 
  than 
  in 
  any 
  <$ 
  Nisoni- 
  

   ades 
  known 
  to 
  me 
  (the 
  ? 
  's, 
  as 
  a 
  rule, 
  having 
  more 
  rounded 
  

   wings), 
  as 
  much 
  so 
  as 
  in 
  JV. 
  Brizo 
  $ 
  . 
  Inner 
  angle 
  rounded, 
  

   with 
  internal 
  margin 
  short. 
  

  

  The 
  usual 
  black 
  markings 
  in 
  the 
  basal 
  region 
  of 
  the 
  wing 
  ; 
  

   the 
  remainder 
  clouded 
  with 
  brown, 
  distinctly 
  relieving 
  the 
  

   transverse 
  line 
  of 
  elongated 
  black 
  spots, 
  and 
  the 
  row 
  of 
  

   rounded 
  submarginal 
  black 
  spots 
  ; 
  a 
  few 
  gray 
  scales 
  are 
  

   sprinkled 
  over 
  the 
  brown 
  ground. 
  The 
  black 
  spots 
  of 
  the 
  

   transverse 
  band 
  above 
  vein 
  2 
  are 
  more 
  elongated 
  in 
  proportion 
  

   to 
  their 
  width, 
  more 
  acute 
  toward 
  the 
  outer 
  margin, 
  and 
  more 
  

   sharply 
  defined 
  than 
  in 
  any 
  other 
  known 
  species 
  — 
  even 
  than 
  

   in 
  N. 
  Ausonius. 
  The 
  line 
  of 
  four 
  small, 
  anteapical, 
  white, 
  

   hyaline 
  spots 
  is 
  sensibly 
  drawn 
  inward 
  toward 
  the 
  base, 
  so* 
  

   that 
  an 
  imaginary 
  line 
  traversing 
  these 
  spots 
  will 
  cut 
  the 
  outer 
  

   margin 
  within 
  its 
  apical 
  half. 
  A 
  white 
  hyaline 
  spot 
  rests 
  on 
  

   the 
  black 
  spot 
  in 
  cell 
  3, 
  and 
  the 
  three 
  black 
  spots 
  in 
  cells 
  2 
  

   and 
  1 
  b, 
  have 
  some 
  gray 
  scales 
  centrally. 
  There 
  is 
  a 
  trace 
  of 
  

   a 
  small, 
  whitish, 
  hyaline, 
  discal 
  spot. 
  The 
  terminal 
  margin 
  

   is 
  without 
  the 
  black 
  line 
  seen 
  in 
  N. 
  Martialis. 
  

  

  Secondaries, 
  dark 
  umber-brown, 
  with 
  the 
  two 
  rows 
  of 
  pale 
  

   brown 
  spots, 
  similar 
  to 
  those 
  of 
  N. 
  Persius 
  $ 
  . 
  

  

  Wings 
  beneath, 
  a 
  rich 
  umber-brown, 
  showing 
  on 
  the 
  prim- 
  

   aries 
  the 
  discal 
  and 
  anteapical 
  spots 
  more 
  plainly 
  than 
  above, 
  

   and 
  a 
  white 
  spot 
  each 
  in 
  cells 
  3 
  and 
  2. 
  The 
  two 
  rows 
  of 
  pale 
  

   brown 
  spots 
  on 
  the 
  secondaries 
  are 
  strongly 
  relieved 
  by 
  the
