  extent 
  in 
  each 
  sex. 
  They 
  also 
  show 
  variation 
  in 
  the 
  shape 
  of 
  

   the 
  subreniform, 
  — 
  that 
  of 
  the 
  female 
  being 
  more 
  oval 
  than 
  in 
  

   the 
  type, 
  and 
  of 
  the 
  male, 
  subquadrangular. 
  

  

  It 
  is 
  believed 
  that 
  the 
  tawny 
  band 
  of 
  the 
  primaries 
  beneath, 
  

   separating 
  the 
  marginal 
  and 
  median 
  black 
  bands, 
  may 
  afford 
  

   valuable 
  differential 
  features 
  in 
  closely 
  allied 
  species 
  of 
  Cato- 
  

   cala. 
  Thus, 
  in 
  the 
  four 
  examples 
  above 
  referred 
  to, 
  the 
  band 
  

   is 
  sharply 
  and 
  almost 
  rectangularly 
  reflected 
  on 
  vein 
  4, 
  thence 
  

   running 
  direct 
  with 
  regular 
  contraction 
  to 
  the 
  internal 
  margin. 
  

  

  In 
  C. 
  eratcegi, 
  the 
  form 
  and 
  course 
  of 
  this 
  band 
  are 
  similar 
  

   to 
  that 
  of 
  C. 
  pretiosa, 
  but 
  its 
  breadth 
  is 
  less. 
  

  

  In 
  one 
  example 
  of 
  C 
  prceclara, 
  the 
  band 
  is 
  less 
  acutely 
  bent 
  

   between 
  veins 
  3 
  and 
  4, 
  and 
  again 
  sharply 
  between 
  veins 
  1 
  and 
  

   2, 
  from 
  which 
  point 
  the 
  lower 
  portion 
  of 
  the 
  median 
  black 
  

   band 
  is 
  continued 
  very 
  narrowly 
  to 
  the 
  inner 
  margin. 
  

  

  In 
  one 
  C.fratercula. 
  female, 
  the 
  tawny 
  band 
  is 
  regularly 
  

   curved, 
  with 
  the 
  exception 
  of 
  a 
  moderate 
  outward 
  bending 
  on 
  

  

  the 
  submedian 
  fold. 
  

  

  • 
  

  

  Mr. 
  Peck 
  informs 
  me 
  that 
  he 
  captured 
  a 
  number 
  of 
  ex- 
  

   amples 
  (12) 
  of 
  pretiosa 
  last 
  year 
  (1876) 
  at 
  Morristown, 
  N. 
  J. 
  

   For 
  several 
  years 
  the 
  species 
  had 
  been 
  in 
  his 
  collection 
  under 
  

   the 
  name 
  of 
  poly 
  gam 
  a. 
  This 
  latter 
  species 
  had 
  never, 
  to 
  his 
  

   knowledge, 
  been 
  taken 
  in 
  the 
  vicinity 
  of 
  Xew 
  York, 
  but 
  he 
  

   had 
  received 
  it 
  (not 
  identified 
  at 
  the 
  time) 
  from 
  Canada. 
  Two 
  

   examples 
  of 
  C. 
  pretiosa 
  were 
  also 
  taken 
  by 
  Mr. 
  F. 
  Tepper, 
  at 
  

   Flatbush, 
  L. 
  I., 
  during 
  the 
  season 
  of 
  1876. 
  

  

  C. 
  polygama, 
  thus 
  far, 
  has 
  proved 
  to 
  be 
  comparatively 
  

   rare.* 
  Its 
  name 
  is 
  probably 
  misapplied 
  in 
  many 
  collections. 
  

   The 
  reference 
  of 
  pretiosa 
  as 
  a 
  variety 
  of 
  that 
  species 
  may 
  be 
  

   presumed 
  to 
  arise 
  from 
  erroneous 
  identification 
  of 
  one 
  or 
  both 
  

   species. 
  

  

  * 
  Both 
  C. 
  pretiosa 
  and 
  C. 
  polygama 
  were 
  collected, 
  at 
  sugar, 
  at 
  Center, 
  in 
  quite 
  a 
  num- 
  

   ber 
  of 
  examples, 
  during 
  July 
  and 
  August 
  of 
  1877. 
  The 
  former 
  species 
  was 
  not 
  at 
  all 
  rare 
  

   throughout 
  the 
  month 
  of 
  July. 
  C. 
  ixAygama 
  was 
  less 
  common, 
  but 
  of 
  longer 
  continuance, 
  

   extending 
  into 
  August.
