  REMARKS 
  ON 
  A 
  SMALL 
  COLLECTION 
  

  

  Aspidiotus 
  orienialis, 
  Newst. 
  

  

  " 
  On 
  banana 
  leaves 
  and 
  on 
  papaw 
  fruit 
  and 
  leaves 
  ; 
  Darwin, 
  N. 
  T., 
  1. 
  i. 
  1914." 
  

   The 
  examples 
  submitted 
  appear 
  to 
  be 
  on 
  the 
  dried 
  rind 
  of 
  the 
  papaw 
  {Papaya 
  

  

  carica), 
  where 
  they 
  occur 
  in 
  large 
  and 
  dense 
  clusters 
  containing 
  both 
  sexes. 
  

  

  This 
  species 
  has 
  not 
  previously 
  been 
  recorded 
  from 
  the 
  Australian 
  region. 
  It 
  

  

  occurs 
  commonly, 
  upon 
  various 
  plants, 
  in 
  India 
  and 
  Ceylon, 
  and 
  I 
  have 
  examples 
  

  

  collected 
  in 
  Arabia. 
  

  

  Aspidiotus 
  (Chrysomphalus) 
  ficus, 
  Ashm. 
  

  

  This 
  cosmopolitan 
  species 
  is 
  represented 
  by 
  heavily 
  infested 
  leaves 
  of 
  coconut 
  palm, 
  

   " 
  Darwin, 
  N. 
  T., 
  10. 
  xii. 
  1913." 
  Also, 
  in 
  association 
  with 
  Mytilaspis 
  citricola, 
  on 
  

   Citrus 
  acida, 
  " 
  Botanic 
  Gardens, 
  Darwin, 
  N. 
  T., 
  12. 
  xii. 
  1913." 
  

  

  Aspidiotus 
  destructor, 
  Sign. 
  

  

  " 
  On 
  leaves 
  of 
  the 
  coconut 
  palm 
  ; 
  Botanic 
  Gardens, 
  Darwin, 
  N. 
  T., 
  11. 
  vi. 
  1913." 
  

  

  Hemichionaspis 
  minor, 
  Mask. 
  

  

  (a) 
  " 
  On 
  Buchanania 
  sp. 
  ; 
  Darwin, 
  N. 
  T., 
  24. 
  i. 
  1914." 
  

  

  The 
  infestation 
  has 
  been 
  very 
  heavy, 
  but 
  has 
  been 
  most 
  effectively 
  checked 
  by 
  the 
  

   agency 
  of 
  natural 
  enemies. 
  Every 
  single 
  individual 
  (and 
  there 
  must 
  have 
  been 
  

   several 
  thousands 
  of 
  them 
  on 
  a 
  single 
  leaf) 
  has 
  been 
  destroyed 
  either 
  by 
  Coccinellid 
  

   beetles 
  or 
  Chalcid 
  parasites. 
  Had 
  it 
  not 
  been 
  for 
  the 
  empty 
  skins 
  of 
  such 
  specimens 
  

   as 
  had 
  fallen 
  victims 
  to 
  the 
  Chalcid, 
  I 
  should 
  have 
  been 
  unable 
  to 
  determine 
  the 
  

   species. 
  Where 
  the 
  Coccinellid 
  has 
  been 
  at 
  work, 
  nothing 
  remains 
  but 
  fragments 
  

   of 
  the 
  puparia.

  " 
  On 
  Kurrajong 
  tree 
  ; 
  Darwin, 
  N. 
  T., 
  24. 
  i. 
  1914." 
  

  

  This 
  sample 
  consists 
  principally 
  of 
  male 
  puparia, 
  massed 
  on 
  the 
  twigs 
  of 
  the 
  tree. 
  

   The 
  few 
  female 
  insects 
  have 
  been 
  exterminated 
  by 
  parasites.

  indigenous 
  vine, 
  Vitis 
  sp. 
  ; 
  Darwin, 
  N.

  1914." 
  

   The 
  same 
  remarks 
  apply 
  to 
  this 
  sample. 
  

  

  Hemichion. 
  minor 
  is 
  recognised, 
  in 
  the 
  United 
  States 
  of 
  America, 
  as 
  an 
  important 
  

   pest 
  of 
  the 
  cotton 
  plant. 
  The 
  Department 
  of 
  Entomology 
  of 
  that 
  country 
  has 
  been 
  

   seriously 
  studying 
  means 
  of 
  combating 
  the 
  pest 
  and 
  has 
  deputed 
  one 
  of 
  its 
  specialists 
  

   to 
  search 
  the 
  world 
  for 
  an 
  effective 
  natural 
  enemy 
  of 
  the 
  insect. 
  Consideration 
  of 
  

   the 
  above 
  samples 
  suggests 
  that 
  such 
  an 
  enemy 
  might 
  be 
  looked 
  for 
  in 
  Northern 
  

   Australia, 
  with 
  some 
  hope 
  of 
  success. 
  

  

  Chionaspis 
  dilatata, 
  Green. 
  

  

  " 
  On 
  Pandanus 
  odoratissimus 
  ; 
  Darwin, 
  N. 
  T., 
  24. 
  i. 
  1914." 
  

  

  This 
  species 
  appears 
  to 
  be 
  widely 
  distributed 
  throughout 
  the 
  Oriental 
  region, 
  but 
  

   has 
  not 
  hitherto 
  been 
  recorded 
  from 
  Australia. 
  Ch. 
  eugeniae, 
  Mask 
  ell, 
  to 
  which 
  it 
  is 
  

   closely 
  allied, 
  differs 
  from 
  dilatata 
  in 
  having 
  the 
  pygidium 
  broadly 
  rounded 
  and 
  the 
  

   median 
  lobes 
  more 
  widely 
  divergent. 
  The 
  species 
  appears 
  to 
  be 
  held 
  in 
  check 
  (in 
  

   Australia) 
  by 
  the 
  same 
  parasites 
  that 
  affect 
  Hemichion. 
  minor.
