  Habitat. 
  — 
  From 
  New 
  York, 
  Pennsylvania, 
  Wisconsin 
  and 
  

   Canada 
  (Montreal). 
  It 
  will 
  probably 
  be 
  found 
  to 
  extend 
  

   throughout 
  most 
  of 
  the 
  eastern 
  portion 
  of 
  the 
  United 
  States. 
  

   It 
  has 
  not, 
  to 
  my 
  knowledge, 
  been 
  observed 
  west 
  of 
  the 
  Miss- 
  

   issippi. 
  

  

  The 
  above 
  insect 
  may 
  be 
  found 
  in 
  nearly 
  all 
  the 
  principal 
  

   collections 
  of 
  the 
  country, 
  under 
  the 
  name 
  of 
  Cerura 
  borealis, 
  

   it 
  being 
  the 
  one 
  which 
  was 
  described 
  by 
  Dr. 
  Harris 
  in 
  his 
  

   Report 
  on 
  the 
  Insects 
  of 
  Massachusetts, 
  1841, 
  p. 
  306, 
  and 
  

   referred 
  by 
  him 
  to 
  the 
  borealis 
  of 
  Dr. 
  Boisduval. 
  The 
  de- 
  

   scription 
  is 
  as 
  follows 
  : 
  

  

  " 
  The 
  ground-color 
  of 
  our 
  moth 
  is 
  dirty 
  white 
  ; 
  the 
  fore-wings 
  

   are 
  crossed 
  by 
  two 
  broad, 
  blackish 
  bands, 
  the 
  outer 
  one 
  of 
  

   which 
  is 
  traversed 
  and 
  interrupted 
  by 
  an 
  irregular, 
  wavy, 
  

   whitish 
  line 
  ; 
  the 
  hinder 
  margins 
  of 
  all 
  the 
  wings 
  are 
  dotted 
  

   with 
  black, 
  and 
  there 
  are 
  several 
  black 
  dots 
  at 
  the 
  base 
  and 
  

   one 
  near 
  the 
  middle 
  of 
  the 
  fore-wings 
  ; 
  the 
  top 
  of 
  the 
  thorax 
  

   is 
  blackish, 
  and 
  the 
  collar 
  is 
  edged 
  with 
  black. 
  In 
  some 
  indi- 
  

   viduals 
  the 
  dusky 
  bands 
  of 
  the 
  fore- 
  wings 
  are 
  edged 
  or 
  dotted 
  

   with 
  tawny 
  yellow 
  ; 
  in 
  others 
  [Cerura 
  cinerea] 
  these 
  wings 
  

   are 
  dusky, 
  and 
  the 
  bands 
  are 
  indistinct. 
  They 
  expand 
  from 
  

   one 
  inch 
  and 
  three-eighths 
  to 
  one 
  inch 
  and 
  three-quarters." 
  

  

  The 
  extrabasilar 
  straight 
  row 
  of 
  five 
  spots 
  readily 
  distin- 
  

   guishes 
  this 
  species 
  from 
  borealis 
  and 
  cinerea 
  (but 
  not 
  from 
  

   aquilonaris) 
  and 
  ally 
  it 
  with 
  furcula 
  and 
  bifida 
  of 
  Europe. 
  

   It 
  is 
  usually 
  of 
  a 
  smaller 
  size 
  than 
  our 
  other 
  species.
