  behind 
  by 
  a 
  similar 
  row. 
  Thorax 
  with 
  elevated 
  purple-black 
  

   and 
  orange 
  scales, 
  which 
  are 
  probably, 
  when 
  in 
  perfect, 
  condi- 
  

   tion, 
  arranged 
  in 
  transverse 
  rows. 
  Abdomen 
  above 
  black, 
  with 
  

   white 
  borders 
  to 
  the 
  segments, 
  which 
  increase 
  in 
  width 
  as 
  they 
  

   recede 
  from 
  the 
  thorax 
  ; 
  a 
  lateral 
  row 
  of 
  black 
  spots 
  ; 
  beneath 
  

   white. 
  

  

  Wings 
  white 
  as 
  in 
  borealis. 
  Primaries 
  with 
  a 
  black 
  basilar 
  

   spot 
  on 
  the 
  subcostal 
  ; 
  beyond, 
  four 
  black 
  spots 
  in 
  a 
  straight 
  

   line, 
  of 
  which 
  the 
  superior 
  one, 
  under 
  a 
  magnifier, 
  is 
  shown 
  

   to 
  be 
  triple 
  and 
  the 
  remaining 
  three, 
  in 
  perfect 
  examples, 
  

   double. 
  Median 
  band 
  consisting 
  of 
  black, 
  orange 
  and 
  pale 
  

   ash 
  scales 
  and 
  prominently 
  bordered 
  with 
  shining 
  purplish- 
  

   black 
  scales. 
  The 
  band, 
  in 
  the 
  female, 
  is 
  twice 
  as 
  broad 
  on 
  the 
  

   costa 
  as 
  on 
  the 
  internal 
  margin, 
  and 
  in 
  the 
  male 
  but 
  one-fourth 
  

   broader 
  costally 
  ; 
  twice 
  equally 
  constricted 
  between 
  the 
  median 
  

   and 
  submedian 
  ; 
  its 
  inner 
  border 
  projected 
  on 
  the 
  subcostal? 
  

   median 
  and 
  submedian 
  nervures, 
  and 
  slightly 
  on 
  the 
  median 
  

   fold, 
  on 
  either 
  side 
  of 
  which 
  the 
  excavations 
  are 
  deeper 
  than 
  

   elsewhere, 
  making 
  the 
  general 
  course 
  of 
  the 
  line 
  a 
  little 
  indi- 
  

   rect 
  ; 
  the 
  outer 
  border 
  projected 
  on 
  the 
  median, 
  median 
  fold 
  

   and 
  submedian. 
  Subterminal 
  band 
  less 
  sharply 
  excavated 
  

   on 
  vein 
  7 
  than 
  in 
  C. 
  occidental-is 
  ; 
  inner 
  border 
  less 
  enlarged 
  

   at 
  internal 
  angle 
  than 
  in 
  C. 
  borealis 
  ; 
  outwardly 
  with 
  a 
  black 
  

   dash 
  before 
  the 
  apex 
  on 
  veins 
  6, 
  7, 
  8 
  and 
  9 
  (the 
  last, 
  costal). 
  

   Of 
  the 
  usual 
  three 
  lines 
  crossing 
  the 
  wing 
  between 
  the 
  median 
  

   and 
  subterminal 
  bands, 
  the 
  anterior 
  one 
  is 
  broken 
  and 
  the 
  

   other 
  two 
  faintly 
  continuous. 
  The 
  terminal 
  intranervular 
  spots 
  

   are 
  smaller 
  than 
  in 
  cinerea, 
  occidentalism 
  borealis 
  or 
  multi- 
  

   scripta. 
  

  

  Secondaries, 
  without 
  a 
  border, 
  but 
  with 
  traces 
  of 
  an 
  obsolete 
  

   outer 
  margin 
  near 
  the 
  apex 
  and 
  more 
  distinctly 
  at 
  the 
  inner 
  

   angle 
  ; 
  a 
  few 
  black 
  scales 
  on 
  the 
  discal 
  cross- 
  vein. 
  

  

  Beneath, 
  the 
  primaries 
  have 
  a 
  distinct 
  discal 
  spot 
  and 
  are 
  

   marked 
  on 
  the 
  costa 
  with 
  black 
  spots 
  at 
  the 
  points 
  where 
  the 
  

   lines 
  of 
  the 
  opposite 
  side 
  commence, 
  which 
  lines 
  are 
  seen 
  in 
  

   transparency.

  From 
  two 
  examples 
  in 
  the 
  Collections 
  of 
  Mr. 
  C. 
  W. 
  Pearson 
  

   and 
  Mr. 
  F. 
  B. 
  Caulfield, 
  of 
  Montreal, 
  captured 
  in 
  that 
  city. 
  

   It 
  is 
  probably 
  quite 
  a 
  rare 
  species.

  This 
  species, 
  which 
  bears 
  a 
  general 
  resemblance 
  to 
  C. 
  borealis,
