﻿of 
  a 
  gynandromorphous 
  Eronia 
  Hippia. 
  .3 
  

  

  abnormal. 
  It 
  is 
  composed 
  partly 
  of 
  the 
  c? 
  valve 
  and 
  

   partly, 
  I 
  think, 
  of 
  the 
  ? 
  clasp. 
  It 
  will 
  be 
  seen 
  from 
  the 
  

   Hgure 
  lal 
  that 
  it 
  is 
  hollowed 
  like 
  a 
  boat, 
  open 
  at 
  one 
  

   end, 
  and 
  terminating 
  in 
  a 
  point 
  at 
  the 
  other, 
  whilst 
  from 
  

   about 
  its 
  centre 
  rises 
  a 
  structure 
  (fig. 
  Ih), 
  which, 
  is 
  

   probably 
  composed 
  of 
  the 
  pendant, 
  already 
  mentioned, 
  

   and 
  the 
  other 
  ? 
  clasp, 
  both 
  being 
  much 
  aborted. 
  The 
  

   two 
  sides 
  of 
  the 
  open 
  end 
  rise 
  into 
  two 
  points, 
  giving 
  the 
  

   organ 
  a 
  curious 
  appearance. 
  

  

  The 
  tegumen 
  and 
  uncus 
  (which 
  Mr. 
  Gosse 
  looked 
  

   upon 
  as 
  separate 
  organs, 
  but 
  which 
  are 
  not 
  so 
  in 
  reality, 
  

   the 
  latter 
  being 
  the 
  terminal 
  joint 
  of 
  the 
  former) 
  are 
  

   very 
  abnormal. 
  

  

  The 
  tegumen 
  (fig. 
  1 
  d), 
  instead 
  of 
  being 
  a 
  regular 
  hood- 
  

   like 
  structure 
  most 
  developed 
  posteriorly, 
  i. 
  e., 
  towards 
  

   the 
  head 
  of 
  the 
  insect, 
  has 
  only 
  quite 
  a 
  slight 
  hood- 
  

   formation 
  at 
  its 
  hinder 
  and 
  upper 
  portion, 
  but 
  is 
  de- 
  

   veloped 
  more 
  forwards, 
  becoming 
  a 
  fairly 
  broad 
  lobe 
  at 
  

   its 
  juncture 
  with 
  the 
  uncus 
  ; 
  furthermore, 
  instead 
  of 
  

   working 
  by 
  a 
  double 
  arm, 
  one 
  on 
  each 
  side 
  the 
  abdomen, 
  

   it 
  has 
  only 
  a 
  single 
  armed 
  attachment 
  on 
  the 
  right 
  side 
  

   (fig. 
  IfU). 
  

  

  The 
  uncus 
  (fig. 
  1 
  c) 
  is 
  simply 
  a 
  finger-like 
  extremity 
  of 
  

   the 
  tegumen, 
  and 
  is 
  abnormally 
  fixed 
  into 
  this 
  organ, 
  

   not 
  jointed 
  to 
  it 
  as 
  usual. 
  

  

  We 
  now 
  come 
  to 
  an 
  organ 
  that 
  has 
  not 
  been 
  mentioned 
  

   (so 
  far 
  as 
  I 
  can 
  find) 
  by 
  any 
  of 
  my 
  predecessors 
  in 
  these 
  

   investigations, 
  viz., 
  a 
  sort 
  of 
  bag 
  or 
  little 
  sack, 
  which 
  I 
  

   will 
  call 
  the 
  " 
  saccus," 
  from 
  the 
  Latin 
  " 
  saccus," 
  a 
  bag 
  

   (figs, 
  le 
  and 
  2e).. 
  It 
  is 
  an 
  organ 
  confined 
  to 
  the 
  male 
  

   sex, 
  wherein 
  the 
  working 
  joints 
  of 
  both 
  valves 
  and 
  tegu- 
  

   men 
  have 
  their 
  seat. 
  In 
  the 
  gynandromorphous 
  speci- 
  

   men 
  this 
  is 
  again 
  abnormal, 
  being 
  simply 
  a 
  longish 
  

   narrow 
  tube 
  affixed 
  on 
  to 
  the 
  posterior 
  extremity 
  of 
  the 
  

   valves, 
  and 
  into 
  which 
  the 
  arm 
  of 
  the 
  tegumen 
  (fig. 
  1 
  d 
  1) 
  

   is 
  also 
  fixed 
  a 
  little 
  further 
  along. 
  

  

  The 
  penis 
  (fig. 
  If) 
  is 
  wonderfully 
  developed, 
  as 
  it 
  is 
  

   in 
  all 
  the 
  species 
  of 
  this 
  genus 
  that 
  I 
  have 
  examined. 
  In 
  

   typical 
  V. 
  Gcea 
  it 
  is 
  a 
  good- 
  sized 
  tube 
  of 
  fairly 
  uniform 
  

   size, 
  but 
  in 
  this 
  specimen 
  it 
  is 
  rather 
  narrower 
  for 
  the 
  

   first 
  three-fifths, 
  when 
  it 
  suddenly 
  expands 
  out 
  into 
  a 
  

   large 
  and 
  broad 
  termination, 
  not 
  unlike 
  the 
  butt-end 
  of 
  

   a 
  rifle. 
  There 
  is 
  also 
  within 
  this 
  organ 
  a 
  sort 
  of 
  mem- 
  

   branous 
  short 
  tubular 
  sack. 
  This 
  member 
  is 
  also
