  ENTOMOLOGICAL 
  MEETING 
  

  

  days 
  it 
  had 
  penetrated 
  a 
  length 
  of 
  20 
  mm. 
  when 
  it 
  began 
  to 
  pupate. 
  

   It 
  had 
  thus 
  killed 
  ofi 
  seven 
  healthy 
  lac 
  females. 
  The 
  caterpillar, 
  when 
  

   full-fed, 
  spins 
  a 
  thin, 
  whitish 
  cocoon. 
  Prior 
  to 
  pupation 
  it 
  makes 
  a 
  

   circular 
  hole 
  on 
  the 
  resinous 
  incrustation 
  which 
  it 
  lines 
  with 
  a 
  thin, 
  

   silken 
  webbing. 
  Such 
  holes 
  of 
  exit 
  for 
  the 
  adult 
  moth 
  could 
  be 
  easily 
  

   seen 
  under 
  the 
  binocular 
  with 
  a 
  little 
  practice. 
  If 
  disturbed, 
  it 
  moves 
  

   about 
  and 
  spins 
  a 
  fresh 
  cocoon 
  either 
  within 
  or 
  between 
  crevices 
  of 
  

   coalescing 
  resinous 
  cells. 
  In 
  the 
  majority 
  of 
  cases 
  examined, 
  the 
  pupa 
  

   lies 
  within 
  the 
  resinous 
  incrustations, 
  in 
  a 
  thin 
  silken 
  cocoon. 
  The 
  

   pupa, 
  when 
  taken 
  out 
  of 
  the 
  cocoon, 
  is 
  brick 
  brown 
  in 
  colour 
  with 
  

   a 
  slight 
  bloom. 
  It 
  is 
  3 
  mm. 
  long 
  and 
  a 
  little 
  over 
  1 
  mm. 
  broad, 
  the 
  

   two 
  black 
  spots 
  on 
  the 
  head 
  representing 
  the 
  eyes. 
  The 
  three 
  pairs 
  

   of 
  legs 
  are 
  folded 
  on 
  the 
  sternum, 
  the 
  apices 
  of 
  the 
  antennae 
  reach 
  the 
  . 
  

   apices 
  of 
  the 
  anterior 
  wings 
  which 
  lie 
  closely 
  adpressed 
  laterally. 
  

   Dorsally 
  the 
  head 
  is 
  pointed 
  anteriorly 
  and 
  broad 
  posteriorly. 
  The 
  

   mesothoracic 
  segment 
  is 
  the 
  most 
  prominent, 
  nearly 
  twice 
  as 
  long 
  as 
  

   pro- 
  and 
  metathoraces 
  together. 
  Eleven 
  abdominal 
  segments 
  are 
  

   distinct. 
  There 
  are 
  a 
  few 
  short 
  white 
  hairs 
  at 
  the 
  anal 
  end. 
  (Plate 
  

   XLIV, 
  fig. 
  6). 
  

  

  The 
  adult 
  moth 
  is 
  pale 
  brown. 
  When 
  resting 
  on 
  lac-covered 
  sticks 
  

   it 
  rests 
  at 
  an 
  angle, 
  the 
  anterior 
  part 
  of 
  the 
  body 
  being 
  slightly 
  raised. 
  

   The 
  moths 
  are 
  not 
  very 
  brisk 
  fliers. 
  They 
  have 
  hitherto 
  been 
  observed 
  

   to 
  be 
  quiet 
  during 
  the 
  greater 
  part 
  of 
  the 
  day. 
  (Plate 
  XLIV, 
  fig. 
  c). 
  

  

  The 
  addition 
  of 
  this 
  moth 
  to 
  the 
  list 
  of 
  predators 
  on 
  the 
  lac 
  insect 
  

   increases 
  the 
  difficulties 
  of 
  cultivation. 
  The 
  lac 
  insects 
  have 
  already 
  

   a 
  host 
  of 
  predators 
  and 
  parasites 
  to 
  contend 
  with. 
  It 
  is 
  just 
  possible 
  

   that 
  this 
  moth, 
  in 
  course 
  of 
  time, 
  may 
  divert 
  its 
  attention 
  from 
  cotton 
  

   to 
  lac 
  and 
  it 
  will 
  then 
  be 
  time 
  to 
  adopt 
  rigorous 
  measures 
  to 
  combat 
  

   it 
  ; 
  when 
  the 
  question 
  of 
  the 
  establishment 
  of 
  nurseries 
  for 
  the 
  distribu- 
  

   tion 
  of 
  broodlac 
  is 
  mooted 
  it 
  will 
  be 
  advisable 
  to 
  keep 
  an 
  eye 
  on 
  this, 
  

   as 
  well 
  as 
  other, 
  predators.
