  In 
  its 
  perfect 
  state 
  the 
  male 
  has 
  a 
  roundish 
  head 
  with 
  two 
  globular 
  eyes 
  

   on 
  its 
  anterior 
  portion, 
  and 
  further 
  back, 
  in 
  the 
  place 
  where 
  the 
  rostrum 
  

   should 
  be, 
  two 
  other 
  eyes 
  (?) 
  filled 
  with 
  a 
  mass 
  of 
  pigment. 
  The 
  antennae 
  

   are 
  long, 
  hairy, 
  ten-jointed. 
  The 
  wings 
  are 
  a 
  little 
  longer 
  than 
  the 
  body. 
  

   The 
  thorax 
  is 
  somewhat 
  broad, 
  with 
  a 
  band 
  crossing 
  it 
  near 
  the 
  middle 
  ; 
  

   this 
  band 
  (seen 
  I 
  believe 
  in 
  all 
  species 
  of 
  Diaspidse) 
  does 
  not 
  in 
  this 
  species 
  

   reach 
  across 
  the 
  whole 
  thorax. 
  The 
  abdomen, 
  smaller 
  than 
  the 
  thorax, 
  is 
  

   oval, 
  and 
  ends 
  in 
  a 
  tubular 
  sheath 
  from 
  which 
  start 
  the 
  two 
  long 
  spikes 
  

   characteristic 
  of 
  the 
  Diaspidse. 
  The 
  legs 
  exhibit 
  a 
  few 
  hairs 
  ; 
  the 
  femora 
  

   are 
  thick; 
  the 
  tibige 
  not 
  very 
  long, 
  narrow 
  ; 
  the 
  tarsi 
  end 
  in 
  the 
  usual 
  single 
  

   claw. 
  

  

  2, 
  Asjndiotus 
  budlcei, 
  Signoret, 
  

  

  On 
  the 
  silver 
  wattle, 
  in 
  Nelson, 
  last 
  year, 
  I 
  found 
  specimens 
  which 
  I 
  

   believe 
  to 
  belong 
  to 
  this 
  species. 
  I 
  have 
  had 
  one 
  or 
  two 
  from 
  a 
  tree 
  of 
  the 
  

   same 
  kind 
  in 
  Christchurch. 
  My 
  specimens 
  are 
  all 
  females. 
  

  

  The 
  difference 
  between 
  this 
  and 
  the 
  last 
  species 
  is, 
  for 
  the 
  female, 
  in 
  

   the 
  number 
  of 
  the 
  spinnerets. 
  These 
  are 
  in 
  four 
  groups, 
  the 
  two 
  upper 
  

   ones 
  having 
  only 
  five 
  or 
  six 
  openings, 
  the 
  two 
  lower 
  only 
  three 
  or 
  four. 
  

  

  It 
  is 
  possible 
  that 
  these 
  specimens 
  may 
  be 
  Aspidiotus 
  aloes. 
  It 
  requires 
  

   an 
  examination 
  of 
  the 
  male 
  to 
  distinguish 
  clearly. 
  

  

  8. 
  Aspidiotus 
  atherospermcB, 
  sp. 
  nov. 
  

  

  I 
  take 
  this 
  to 
  be 
  a 
  new 
  species 
  ; 
  I 
  have 
  it 
  from 
  an 
  indigenous 
  tree, 
  

   Atherosperma 
  novce-zealandice. 
  The 
  puparium 
  resembles 
  that 
  of 
  Aspidiotus 
  

   epidendri, 
  but 
  is 
  somewhat 
  darker 
  in 
  colour. 
  The 
  adult 
  female 
  is 
  much 
  

   more 
  corrugated, 
  and 
  the 
  corrugations 
  overlap 
  the 
  abdominal 
  region. 
  The 
  

   pygidium 
  has 
  four 
  groups 
  of 
  spinnerets 
  ; 
  the 
  upper 
  pair 
  have 
  15 
  openings, 
  

   the 
  lower 
  9 
  or 
  10. 
  The 
  abdomen 
  ends 
  in 
  several 
  lobes, 
  of 
  which 
  the 
  four 
  

   middle 
  ones 
  are 
  the 
  largest. 
  The 
  rest 
  of 
  the 
  lobes 
  are 
  sharply 
  pointed. 
  

   Between 
  the 
  lobes 
  are 
  scaly 
  serrated 
  hairs. 
  

  

  Plate

  the 
  adult 
  female 
  and 
  the 
  abdomen.

  Plate 
  VI., 
  fig. 
  7. 
  

  

  The 
  puparium 
  is 
  brown, 
  somewhat 
  convex, 
  the 
  underside 
  white. 
  The 
  

   female 
  in 
  the 
  middle 
  is 
  bright 
  yellow, 
  corrugated, 
  the 
  corrugations 
  over- 
  

   lapping 
  the 
  abdominal 
  region 
  which 
  is 
  comparatively 
  small. 
  There 
  are 
  

   four 
  groups 
  of 
  spinnerets 
  — 
  the 
  upper 
  pair 
  with 
  ten 
  openings, 
  the 
  lower 
  with 
  

   nine, 
  many 
  scattered 
  oval 
  and 
  oblong 
  spinnerets. 
  The 
  abdomen 
  ends 
  in 
  

   six 
  lobes, 
  of 
  which 
  only 
  the 
  two 
  median 
  are 
  conspicuous 
  ; 
  between 
  the 
  lobes 
  

   fine, 
  serrated 
  hah-s. 
  The 
  abdomen 
  is 
  very 
  velvety. 
  

  

  In 
  the 
  second 
  stage, 
  shown 
  in 
  plate 
  VI., 
  fig. 
  7c, 
  the 
  body 
  is 
  more 
  oval 
  

   and 
  less 
  corrugated, 
  and 
  the 
  rostral 
  set^ 
  are 
  exceedingly 
  long.
