  With 
  the 
  exceptiou 
  of 
  the 
  ahdominal 
  lobes 
  aud 
  the 
  numhers 
  of 
  spinnerets 
  

   in 
  the 
  groups, 
  the 
  adult 
  female 
  resembles 
  Aspidiotus 
  atherospermee.

  This 
  is 
  not 
  an 
  indigenous 
  species, 
  being 
  found 
  in 
  immense 
  numbers 
  

   upon 
  the 
  oranges 
  and 
  lemons 
  in 
  our 
  shops, 
  imported 
  from 
  Sydney. 
  As, 
  

   however, 
  it 
  occurs 
  ou 
  orange 
  trees 
  growing 
  at 
  Governor's 
  Bay, 
  I 
  introduce 
  

   it 
  here. 
  

  

  M. 
  Signoret 
  describes, 
  under 
  the 
  name 
  of 
  Parlatoria 
  zizyphi, 
  or 
  aurantii, 
  

   an 
  insect 
  infesting 
  orange 
  trees 
  in 
  Europe. 
  Its 
  form, 
  as 
  given 
  in 
  his 
  plate 
  

   v., 
  fig. 
  9, 
  bears 
  certainly 
  great 
  general 
  resemblance 
  to 
  the 
  insect 
  I 
  am 
  

   describing, 
  but 
  it 
  differs 
  altogether 
  in 
  the 
  shape 
  and 
  colour 
  of 
  the 
  puparium, 
  

   and 
  the 
  abdominal 
  lobes 
  are 
  also 
  different. 
  

  

  The 
  puparium 
  of 
  Aspidiotus 
  aurantii 
  is 
  round, 
  yellowish, 
  flat. 
  The 
  

   insect, 
  in 
  the 
  centre, 
  is 
  curiously 
  shaped. 
  It 
  has 
  a 
  generally 
  spherical 
  out- 
  

   line, 
  but 
  looks 
  as 
  if, 
  from 
  rich 
  feeding, 
  rolls 
  of 
  fat 
  were 
  produced, 
  making 
  

   the 
  corrugations 
  of 
  the 
  body 
  very 
  largely 
  overlap 
  the 
  abdomen. 
  It 
  is 
  

   yellow, 
  the 
  abdomen 
  being 
  the 
  deepest 
  coloured. 
  The 
  ciu've 
  of 
  the 
  body 
  

   and 
  head 
  is 
  regular 
  aud 
  smooth; 
  the 
  rudimentary 
  antennae 
  are 
  absent 
  ; 
  the 
  

   abdominal 
  region, 
  very 
  small 
  in 
  comparison 
  with 
  the 
  rest, 
  ends 
  in 
  six 
  lobes 
  

   of 
  which 
  the 
  two 
  middle 
  ones 
  are 
  the 
  largest. 
  There 
  are 
  no 
  groups 
  of 
  

   spinnerets. 
  

  

  The 
  young 
  insect 
  (second 
  stage) 
  is 
  somewhat 
  different, 
  being 
  of 
  a 
  nearly 
  

   regular 
  oval 
  shape, 
  without 
  the 
  rolls 
  of 
  fat. 
  

  

  The 
  male 
  is 
  very 
  smaU, 
  brown 
  in 
  colour 
  ; 
  the 
  antennae 
  have 
  ten 
  joints. 
  

   The 
  two 
  first 
  joints 
  are 
  very 
  small, 
  round 
  and 
  smooth 
  ; 
  the 
  third, 
  fourth, 
  

   fifth 
  and 
  sixth 
  equal 
  in 
  length, 
  the 
  seventh, 
  eighth 
  and 
  ninth 
  half 
  as 
  long, 
  

   the 
  tenth 
  somewhat 
  shorter 
  still 
  and 
  pointed. 
  All 
  the 
  last 
  eight 
  joints 
  show 
  

   numerous 
  hairs. 
  The 
  thorax 
  is 
  short 
  and 
  thick, 
  the 
  thoracic 
  band 
  occupy- 
  

   ing 
  more 
  than 
  one-half 
  the 
  width 
  ; 
  the 
  abdomen 
  short, 
  the 
  double 
  spike 
  of 
  

   some 
  length. 
  The 
  wings 
  are 
  oval, 
  about 
  as 
  long 
  as 
  the 
  body. 
  The 
  legs 
  

   are 
  hau-y, 
  femora 
  thick, 
  tibi^ 
  longer, 
  thicker 
  at 
  the 
  end 
  next 
  the 
  tarsus 
  than 
  

   at 
  the 
  other 
  end 
  ; 
  tarsi 
  broad 
  at 
  the 
  top, 
  tapering 
  gradually 
  down 
  to 
  the 
  

   usual 
  single 
  claw. 
  The 
  hairs 
  on 
  the 
  femora 
  are 
  much 
  fewer 
  than 
  those 
  on 
  

   the 
  tibias 
  and 
  tarsi. 
  

  

  This 
  insect 
  does 
  not 
  correspond 
  in 
  any 
  particular 
  with 
  the 
  species 
  

   described 
  by 
  M. 
  Signoret, 
  except 
  in 
  the 
  general 
  outhne 
  of 
  the 
  adult 
  female, 
  

   resembling 
  Parlatoria. 
  Nevertheless, 
  as 
  it 
  is 
  manifestly 
  not 
  a 
  species 
  

   indigenous 
  to 
  New 
  Zealand 
  and 
  must 
  be 
  known 
  to 
  entomologists, 
  I 
  give 
  it 
  

   the 
  name 
  of 
  Aspidiotus 
  aurantii 
  only 
  in 
  default 
  of 
  better 
  information 
  than 
  I 
  

   have 
  at 
  present.

  Schrader,
