  Cerura 
  occidentalis 
  n. 
  sp. 
  

  

  Head 
  white. 
  Palpi 
  white, 
  blackish 
  laterally. 
  Antennae 
  

   white 
  with 
  black 
  pectinations. 
  

  

  Collar 
  pale 
  cinereous, 
  traversed 
  by 
  a 
  darker 
  band 
  and 
  edged 
  

   behind 
  by 
  a 
  black

  Tegulse 
  pale 
  cinereous, 
  darker 
  pos- 
  

   teriorly 
  ; 
  the 
  narrow 
  black 
  band 
  crossing 
  their 
  front, 
  followed 
  

   by 
  a 
  patch 
  of 
  orange 
  scales, 
  and 
  a 
  few 
  black 
  scales 
  on 
  their 
  

   inner 
  side. 
  Thorax 
  marked 
  with 
  black 
  and 
  orange 
  bands 
  of 
  

   raised 
  scales 
  (apparently 
  three 
  orange 
  bands).* 
  

  

  Abdomen 
  above 
  cinereous, 
  the 
  segments 
  bordered 
  behind 
  

   with 
  pale 
  cinereous 
  ; 
  beneath 
  whitish 
  ; 
  sides 
  tufted 
  with 
  a 
  

   lateral 
  row 
  of 
  small 
  black 
  spots. 
  

  

  Primaries 
  whitish 
  basally, 
  sprinkled 
  with 
  some 
  black 
  hairs 
  ; 
  

   medially 
  and 
  terminally 
  pale 
  cinereous 
  with 
  more 
  numerous 
  

   black 
  hairs. 
  A 
  black 
  basal 
  dot 
  on 
  the 
  subcostal 
  ; 
  an 
  extra- 
  

   basilar 
  row 
  of 
  five 
  black 
  spots 
  on 
  the 
  nervures, 
  usually, 
  in 
  

   the 
  males, 
  in 
  a 
  straight 
  line 
  (5 
  examples), 
  but 
  sometimes 
  the 
  

   two 
  superior 
  are 
  nearer 
  the 
  base 
  (2 
  examples)f; 
  in 
  the 
  ? 
  's 
  (5 
  ex- 
  

   amples) 
  the 
  two 
  superior 
  spots 
  are 
  considerably 
  drawn 
  in 
  

   toward 
  the 
  base, 
  the 
  line 
  presenting 
  quite 
  a 
  curve 
  costally. 
  

   The 
  median 
  band 
  of 
  black 
  and 
  a 
  few 
  orange 
  scales, 
  paler 
  than 
  

   in 
  borealis 
  and 
  aquilonaris, 
  broadest 
  on 
  the 
  costa, 
  elsewhere 
  

   of 
  nearly 
  uniform 
  width 
  ; 
  its 
  black 
  borders 
  subparallel 
  ; 
  the 
  

   inner 
  border 
  more 
  distinctly 
  marked 
  ; 
  its 
  general 
  course 
  in 
  the 
  

   male, 
  direct 
  or 
  slightly 
  excavating 
  the 
  band 
  below 
  the 
  median, 
  

   while 
  in 
  the 
  female 
  it 
  is 
  conspicuously 
  bent, 
  on 
  or 
  below 
  the 
  

   same 
  nervure 
  ; 
  the 
  outer 
  border 
  usually 
  not 
  well 
  defined 
  below 
  

   the 
  submedian 
  fold, 
  Behind 
  the 
  median 
  band, 
  a 
  black 
  trans- 
  

   verse 
  line, 
  interrupted 
  on 
  the 
  cell 
  and 
  indistinct 
  over 
  the 
  sub- 
  

   median 
  fold. 
  On 
  the 
  discal 
  cross-vein, 
  an 
  elongated 
  black 
  

   spot. 
  Beyond 
  this, 
  two 
  or 
  three 
  subparallel 
  crescentiform 
  

  

  *A 
  cabinet 
  specimen 
  of 
  this 
  species 
  is 
  rarely 
  seen, 
  in 
  which 
  the 
  thoracic 
  scales 
  

   have 
  not 
  been 
  so 
  affected 
  by 
  greasing, 
  that 
  the 
  bands 
  can 
  with 
  difficulty 
  be 
  traced. 
  

  

  fin 
  five 
  examples 
  of 
  the 
  European 
  bifida, 
  this 
  line 
  curves 
  outwardly 
  at 
  the 
  

   costal 
  or 
  on 
  the 
  inner 
  margin 
  ; 
  in 
  one 
  example 
  (female) 
  it 
  is 
  straight.
