  and 
  tegumen 
  are 
  affixed, 
  is 
  a 
  well-developed 
  bag, 
  rounded 
  

   at 
  the 
  bottom 
  and 
  open, 
  as 
  a 
  bag, 
  at 
  the 
  top. 
  

  

  The 
  penis 
  (fig. 
  2/) 
  is 
  rounded 
  at 
  its 
  hinder 
  extremity, 
  

   of 
  moderately 
  uniform 
  width, 
  slightly 
  expanding 
  near 
  its 
  

   tip, 
  where 
  it 
  is 
  wrapped 
  up 
  into 
  many 
  small 
  folds, 
  and 
  

   from 
  this 
  is, 
  I 
  suppose, 
  capable 
  of 
  grea 
  expansion 
  at 
  

   this 
  end 
  (see 
  also 
  fig. 
  2 
  a). 
  

  

  The 
  external 
  genitalia 
  of 
  the 
  ? 
  GcEa 
  are 
  shown 
  at 
  

   fig. 
  3, 
  and 
  consist 
  of 
  a 
  very 
  simple 
  pair 
  of 
  clasps, 
  if 
  I 
  

   may 
  so 
  term 
  them 
  : 
  they 
  usually 
  spring 
  from 
  the 
  upper 
  

   part 
  of 
  the 
  abdomen, 
  and 
  incline 
  downwards, 
  and 
  are 
  

   mostly 
  covered 
  wilh 
  a 
  mass 
  of 
  fine 
  bristles, 
  each 
  arising 
  

   from 
  a 
  small 
  warty 
  protuberance. 
  

  

  It 
  will 
  be 
  seen 
  from 
  these 
  descriptions 
  and 
  figures 
  that 
  

   the 
  gynandromorphous 
  specimen 
  is 
  more 
  of 
  a 
  <? 
  than 
  ? 
  

   in 
  its 
  generic 
  organs. 
  The 
  wings 
  similarly 
  coincide 
  with 
  

   the 
  genitalia, 
  the 
  right 
  wings 
  having 
  $• 
  coloration, 
  and 
  

   the 
  left 
  ? 
  ; 
  whilst 
  in 
  like 
  manner 
  the 
  right 
  organs 
  

   are 
  more 
  characteristic 
  of 
  the 
  <y 
  than 
  those 
  on 
  the 
  left 
  

   side. 
  

  

  I 
  will 
  now 
  draw 
  attention 
  to 
  a 
  very 
  curious 
  organ 
  

   found 
  occasionally 
  in 
  the 
  ovarian 
  sack 
  of 
  many 
  lepi- 
  

   dopterous 
  genera 
  (but 
  more 
  especially, 
  I 
  believe, 
  in 
  

   the 
  Pieridce), 
  which 
  is 
  present 
  both 
  in 
  the 
  abnormal 
  

   v. 
  GcEa, 
  and 
  also 
  in 
  the 
  normal 
  female 
  examined 
  by 
  me. 
  

   These 
  are 
  figured 
  at 
  1 
  d 
  and 
  4. 
  The 
  shapes 
  vary 
  much 
  

   in 
  different 
  genera, 
  but, 
  so 
  far 
  as 
  my 
  experience 
  goes, 
  

   each 
  genus 
  follows 
  one 
  form 
  in 
  a 
  more 
  or 
  less 
  modified 
  

   shape 
  ; 
  for 
  instance, 
  among 
  the 
  earlier 
  Pieridce 
  the 
  form 
  

   is 
  generally 
  somewhat 
  akin 
  to 
  fig. 
  4, 
  viz., 
  the 
  normal 
  v. 
  

   Gcea, 
  which 
  is 
  doubly 
  ovate, 
  joined 
  together 
  by 
  a 
  narrow 
  

   neck, 
  and 
  studded 
  all 
  over 
  with 
  formidable 
  teeth. 
  It 
  is 
  

   enclosed 
  in 
  a 
  tight-fitting 
  sack 
  (not 
  visible 
  in 
  my 
  figure, 
  

   as 
  I 
  only 
  discovered 
  it 
  when 
  closely 
  examining 
  the 
  organ 
  

   under 
  a 
  high 
  power). 
  From 
  this 
  form 
  it 
  becomes 
  much 
  

   modified 
  as 
  we 
  approach 
  the 
  genus 
  Colias, 
  where 
  its 
  

   shape 
  almost 
  entirely 
  loses 
  the 
  ovate 
  appearance. 
  It 
  will 
  

   be 
  seen 
  from 
  fig. 
  Id 
  that 
  in 
  the 
  gynandromorphous 
  

   specimen 
  its 
  form 
  is 
  simpler, 
  being 
  somewhat 
  that 
  of 
  a 
  

   thick 
  short 
  club, 
  which 
  is 
  destitute 
  of 
  the 
  close-fitting 
  

   sack, 
  but 
  lies 
  bare 
  within 
  the 
  ovarian 
  sack, 
  this 
  being 
  

   quite 
  distinct 
  from 
  the 
  former 
  one. 
  The 
  only 
  work 
  in 
  

   which 
  I 
  can 
  find 
  any 
  mention 
  of 
  this 
  organ 
  is 
  in 
  that 
  

   most 
  valuable 
  one 
  by 
  Salvin 
  and 
  Godman.
