  scale-bugs. 
  His 
  experience 
  was 
  that 
  ladybirds 
  suffered 
  little 
  

   from 
  cyaniding 
  because 
  they 
  were 
  generally 
  shaken 
  to 
  the 
  ground 
  

   in 
  the 
  course 
  of 
  mounting 
  the 
  tent, 
  and 
  as 
  the 
  gas 
  rose, 
  the 
  lady- 
  

   birds 
  usually 
  revived, 
  flying 
  away 
  soon 
  after 
  the 
  removal 
  of 
  the 
  

   tent. 
  In 
  the 
  apple 
  orchards 
  which 
  are 
  infested 
  much 
  by 
  the 
  

   codlin 
  moth, 
  spraying 
  with 
  lead 
  arsenate 
  is 
  the 
  common 
  practice. 
  

   Perhaps 
  the 
  most 
  serious 
  pest 
  of 
  the 
  whole 
  country 
  is 
  the 
  com- 
  

   paratively 
  recently 
  introduced 
  Mediterranean 
  fruit-fly 
  (Ceratitis 
  

   capitata), 
  and 
  the 
  Queensland 
  fruit 
  fly 
  ( 
  Daais 
  tryoni) 
  . 
  It 
  has 
  

   been 
  recently 
  discovered 
  that 
  kerosene 
  oil 
  is 
  an 
  irresistible 
  attrac- 
  

   tion 
  to 
  the 
  Mediterranean 
  fly 
  and 
  the 
  hope 
  is 
  now 
  entertained 
  that 
  

   by 
  trapping 
  the 
  flies 
  with 
  this 
  oil, 
  their 
  ravages 
  will 
  be 
  consider- 
  

   ably 
  checked. 
  The 
  oil, 
  however, 
  seems 
  to 
  have 
  no 
  attraction 
  for 
  

   the 
  Queensland 
  fruit-fly 
  ( 
  Daais 
  tryoyii) 
  . 
  In 
  the 
  fight 
  against 
  

   Phylloxera, 
  the 
  use 
  of 
  resistant 
  stocks 
  offers 
  relief. 
  The 
  San 
  Jose 
  

   scale, 
  at 
  first 
  very 
  numerous 
  and 
  injurious 
  to 
  fruit-trees, 
  is 
  now 
  

   kept 
  well 
  in 
  check 
  by 
  a 
  number 
  of 
  enemies, 
  the 
  most 
  effective, 
  per- 
  

   haps, 
  being 
  a 
  lepidopterous 
  larva* 
  described 
  by 
  Mr. 
  Froggatt 
  not 
  

   long 
  ago. 
  The 
  Chinese 
  wax-scale 
  ( 
  Ceroplastcs 
  ceriierus) 
  frequently 
  

   inhabits 
  fruit-trees 
  in 
  large 
  numbers, 
  but 
  it 
  does 
  not 
  seem 
  to 
  have 
  

   the 
  poisoning 
  effect 
  upon 
  plant 
  tissues 
  that 
  the 
  San 
  Jose 
  and 
  other 
  

   scales 
  have. 
  A 
  wash 
  composed 
  of 
  a 
  couple 
  of 
  pounds 
  of 
  washing 
  

   soda 
  to 
  a 
  bucket 
  of 
  water 
  is 
  the 
  most 
  effective 
  remedy 
  so 
  far 
  

   used. 
  

  

  Mr. 
  Froggatt 
  then 
  referred 
  to 
  the 
  Linnean 
  Society 
  of 
  New 
  

   South 
  Wales 
  as 
  an 
  old 
  and 
  well 
  established, 
  and 
  one 
  of 
  wealthiest 
  

   organizations 
  of 
  the 
  kind 
  in 
  the 
  world. 
  Our 
  fellow 
  members. 
  

   Dr. 
  Perkins 
  and 
  Messrs. 
  Kirkaldy 
  and 
  Terry, 
  are 
  members 
  of 
  the 
  

   Society. 
  While 
  it 
  is 
  not 
  a 
  strictly 
  entomological 
  society, 
  the 
  

   volumes 
  published 
  (now 
  amounting 
  to 
  32) 
  contain 
  a 
  great 
  amount 
  

   of 
  entomological 
  matter. 
  Though 
  the 
  Field 
  Naturalist's 
  Societies 
  

   of 
  Australia 
  have 
  a 
  large 
  membership, 
  they 
  are 
  not 
  confined 
  to 
  

   entomological 
  work, 
  and 
  in 
  entomology 
  they 
  limit 
  themselves 
  

   practically 
  to 
  life 
  histories. 
  

  

  Speaking 
  of 
  his 
  own 
  mission 
  around 
  the 
  world, 
  which 
  brought 
  

   him 
  to 
  the 
  Hawaiian 
  Islands, 
  Mr. 
  Froggatt 
  was 
  proud 
  to 
  have 
  

   been 
  chosen 
  by 
  l)oth 
  the 
  State 
  Officials 
  and 
  Entomologists 
  of
