  Thirtieth 
  Report 
  on 
  the 
  State 
  Museum. 
  [66] 
  

  

  It 
  is 
  very 
  desirable 
  that 
  large 
  collections 
  of 
  these 
  forms 
  

   should 
  be 
  made 
  for 
  study, 
  and 
  that 
  broods 
  of 
  them 
  be 
  reared 
  

   from 
  captured 
  females 
  imprisoned 
  over 
  their 
  food- 
  plant, 
  upon 
  

   the 
  plan 
  practised 
  by 
  Mr. 
  Edwards 
  with 
  such 
  signal 
  success, 
  

   and 
  extremely 
  valuable 
  results.
