  the 
  cell, 
  with 
  an 
  outward 
  inflection 
  from 
  the 
  costa 
  to 
  the 
  sub- 
  

   costal 
  nervure, 
  an 
  inward 
  inflection 
  in 
  the 
  cell 
  to 
  the 
  first 
  

   median 
  nervule 
  which 
  it 
  follows 
  for 
  a 
  short 
  distance, 
  and 
  

   thence 
  proceeds 
  in 
  a 
  double 
  curve 
  to 
  the 
  internal 
  margin. 
  

   Another 
  black 
  line, 
  less 
  heavily 
  marked, 
  runs 
  irregularly 
  

   from 
  the 
  costa 
  to 
  the 
  internal 
  margin, 
  passing 
  over 
  the 
  middle 
  

   of 
  the 
  cell. 
  Between 
  the 
  stronger 
  transverse 
  lines 
  are 
  fainter 
  

   ones, 
  which 
  sometimes 
  reticulate 
  with 
  the 
  former. 
  The 
  thorax, 
  

   abdomen, 
  basal 
  and 
  internal 
  portion 
  of 
  the 
  hind 
  wings, 
  are 
  

   thickly 
  clothed 
  with 
  pale 
  gray 
  hairs 
  or 
  elongated 
  scales 
  : 
  

   the 
  remaining 
  portion 
  of 
  the 
  hind 
  wings 
  (the 
  portion 
  preserved 
  

   in 
  the 
  example) 
  is 
  as 
  thickly 
  scaled 
  as 
  the 
  primaries, 
  and 
  nearly 
  

   as 
  distinctly 
  lined 
  ; 
  beneath 
  they 
  are 
  stronger 
  lined 
  than 
  above. 
  

   Palpi 
  barely 
  extending 
  beyond 
  the 
  eyes, 
  clothed 
  with 
  white 
  

   scales 
  interspersed 
  with 
  narrow 
  black 
  ones. 
  Thorax 
  beneath, 
  

   with 
  long 
  gray 
  hairs. 
  Legs 
  similarly 
  clothed, 
  with 
  their 
  tibise 
  

   and 
  tarsi 
  banded 
  with 
  black. 
  

  

  Length 
  of 
  body, 
  with 
  extruded 
  ovipositor, 
  1.50 
  inch. 
  Ex- 
  

   panse 
  of 
  wings, 
  entire, 
  unknown 
  ; 
  from 
  one 
  discal 
  cross- 
  vein 
  

   to 
  the 
  opposite, 
  1.85 
  inch. 
  

  

  The 
  pupa-case 
  projecting 
  from 
  the 
  tree, 
  was 
  that 
  of 
  a 
  moth 
  

   differing 
  in 
  sex 
  from 
  the 
  captured 
  example, 
  but 
  presumably 
  of 
  

   the 
  same 
  species. 
  It 
  measures 
  1.40 
  in. 
  in 
  length 
  and 
  0.3 
  in. 
  

   in 
  its 
  broadest 
  diameter. 
  Its 
  color 
  is 
  about 
  that 
  of 
  the 
  ? 
  of 
  

   0. 
  roMnicB, 
  but 
  of 
  a 
  paler 
  brown 
  than 
  the 
  $ 
  of 
  that 
  species. 
  

   Its 
  terminal 
  segment 
  and 
  rows 
  of 
  teeth 
  on 
  the 
  segments 
  are 
  

   darker 
  brown, 
  approaching 
  fuscous, 
  but 
  presenting 
  quite 
  a 
  

   contrast 
  with 
  the 
  black 
  terminal 
  segment 
  and 
  wing-cases 
  of 
  

   O. 
  Oenterensis. 
  Its 
  armature 
  (transverse 
  rows 
  of 
  teeth) 
  is 
  

   much 
  stronger 
  than 
  in 
  the 
  ? 
  C. 
  rohinice, 
  and 
  a 
  little 
  more 
  so 
  

   than 
  in 
  the 
  $ 
  . 
  It 
  is 
  stronger 
  than 
  in 
  O. 
  Oenterensis 
  (in 
  which 
  

   the 
  armature 
  is 
  nearly 
  equal 
  in 
  the 
  sexes), 
  having 
  the 
  teeth 
  

   longer, 
  although 
  not 
  so 
  broad 
  at 
  their 
  base 
  : 
  on 
  the 
  8th, 
  9th 
  and 
  

   10th 
  segments, 
  the 
  teeth 
  continue 
  quite 
  prominent 
  in 
  their 
  ex- 
  

   tension 
  below 
  the 
  stigmata, 
  where 
  in 
  O. 
  Oenterensis 
  they 
  are 
  

   weak. 
  

  

  The 
  armature 
  of 
  the 
  pupa-cases 
  of 
  Cossus, 
  unquestionably 
  

   presents 
  excellent 
  specific 
  characters. 
  From 
  its 
  study, 
  I 
  am 
  

   able 
  to 
  announce 
  the 
  existence, 
  in 
  the 
  State 
  of 
  New 
  York, 
  of 
  

   another 
  species 
  of 
  Cossus, 
  boring 
  in 
  the 
  white 
  birch 
  (Betula 
  

   populifoMa), 
  the 
  imago 
  of 
  which 
  has 
  not 
  yet 
  been 
  detected.
