  PROCEEDINGS 
  OF 
  THE 
  FOURTH 
  ENTOMOLOGICAL 
  MEETING 
  

  

  The 
  cocoon 
  is 
  spherical 
  and 
  kept 
  in 
  place 
  between 
  the 
  leaflets 
  by 
  a 
  

   tangle 
  of 
  silk 
  threads. 
  

  

  The 
  pupa 
  is 
  6 
  mm. 
  in 
  length, 
  stout 
  and 
  roughly 
  oval. 
  Eyes 
  are 
  

   prominent, 
  wing 
  rudiments 
  plainly 
  seen 
  and 
  extending 
  to 
  eighth 
  

   abdominal 
  segment. 
  They 
  are 
  separated 
  medianally 
  by 
  leg 
  rudiments. 
  

   Between 
  eyes 
  is 
  a 
  broadenad 
  cross 
  ridge 
  of 
  chitin. 
  Posterior 
  end 
  

   is 
  blunt 
  and 
  

  

  The 
  moth 
  has 
  already 
  been 
  described. 
  It 
  possesses 
  the 
  rather 
  quaint 
  

   habit 
  of 
  sitting 
  up 
  like 
  a 
  " 
  begging 
  dog." 
  

  

  One 
  unfertilized 
  moth 
  lived 
  in 
  laboratory, 
  21st-25th 
  January 
  1914 
  ; 
  

   fertilized 
  moths 
  lived 
  from 
  4 
  to 
  9 
  days. 
  The 
  average 
  life 
  appeared 
  to 
  be 
  

   5 
  days 
  but 
  this 
  was 
  under 
  Insectary 
  conditions 
  and 
  not 
  the 
  actual 
  life 
  

   in 
  nature.
