  PROCEEDINGS 
  OF 
  THE 
  FOURTH 
  ENTOMOLOGICAL 
  MEETING 
  

  

  Nagpur, 
  Baroda 
  and 
  Ceylon. 
  I 
  am 
  nob 
  sare 
  of 
  the 
  sp83i83 
  of 
  Oj)yjaren^is 
  

   occnrring 
  on 
  cotton 
  in 
  Ceylon 
  but 
  the 
  Indian 
  speoies 
  seejis 
  to 
  be 
  Ojcjsa- 
  

   renus 
  Icetus. 
  

  

  The 
  adults 
  as 
  well 
  as 
  the 
  nymphs 
  freely 
  move 
  about 
  the 
  cotton 
  plant, 
  

   more 
  so 
  in 
  the 
  bolls. 
  They 
  attack 
  the 
  cotton 
  seed 
  for 
  the 
  sake 
  of 
  the 
  

   mucilaginous 
  matter 
  within 
  them. 
  If, 
  however, 
  an 
  aSected 
  seed 
  is 
  cut 
  

   open 
  and 
  examined, 
  it 
  will 
  be 
  found 
  discoloured 
  within. 
  If 
  the 
  lint 
  

   be 
  digested, 
  and 
  the 
  coating 
  of 
  the 
  shell 
  examined 
  under 
  high 
  power, 
  

   it 
  will 
  be 
  found 
  to 
  contain 
  a 
  number 
  of 
  very 
  fine 
  holes, 
  probably 
  the 
  

   pricks 
  made 
  by 
  the 
  rostrum 
  of 
  the 
  bug. 
  It 
  moves 
  about 
  freely 
  in 
  the 
  

   bolls 
  and 
  the 
  seeds 
  in 
  bolls 
  are 
  pricked 
  by 
  a 
  number 
  of 
  adults 
  passing 
  

   the 
  half-opened 
  bolls. 
  It 
  has 
  wings 
  but 
  they 
  do 
  not 
  seem 
  to 
  be 
  functional. 
  

   It 
  runs 
  fast 
  and 
  seldom 
  uses 
  them 
  for 
  flight. 
  

  

  The 
  eggs 
  are 
  laid 
  in 
  the 
  lint 
  of 
  the 
  half-opened 
  bolls, 
  between 
  the 
  

   calyx 
  and 
  the 
  boll, 
  but 
  when 
  the 
  egg 
  laying 
  is 
  at 
  its 
  maximum, 
  eggs 
  may 
  

   also 
  be 
  seen 
  laid 
  at 
  random 
  on 
  the 
  bolls, 
  the 
  flowers 
  and 
  flower 
  and 
  leaf 
  

   buds. 
  The 
  eggs 
  are 
  laid 
  either 
  singly 
  or 
  in 
  small 
  clusters 
  varying 
  from 
  

   two 
  or 
  three 
  to 
  eighteen, 
  the 
  largest 
  number 
  of 
  eggs 
  as 
  yet 
  found 
  in 
  a 
  

   cluster. 
  An 
  occasional 
  count 
  of 
  the 
  eggs 
  in 
  various 
  clusters 
  found 
  on 
  the 
  

   lint 
  and 
  the 
  parts 
  of 
  the 
  boll 
  was 
  —
