  The 
  antenna 
  and 
  feet 
  do 
  not, 
  as 
  long 
  as 
  the 
  fringe 
  is 
  present, 
  differ 
  

   from 
  those 
  of 
  C. 
  perforatiis. 
  In 
  the 
  Liter 
  stage, 
  when 
  the 
  insect 
  has 
  

   attained 
  its 
  full 
  size, 
  they 
  hecome 
  very 
  small 
  proportionately, 
  indeed 
  

   almost 
  atrophied, 
  and 
  difficult 
  to 
  make 
  out. 
  Maceration 
  in 
  potash 
  shows 
  

   them 
  as 
  existing, 
  hut 
  they 
  can 
  be 
  of 
  no 
  use 
  to 
  the 
  insect. 
  I 
  cannot 
  detect 
  

   any 
  difference 
  between 
  them 
  and 
  the 
  antennae 
  and 
  feet 
  of 
  C. 
  perforatus, 
  

   except 
  their 
  comparative 
  smallness. 
  

  

  The 
  edge 
  of 
  the 
  female 
  in 
  the 
  earlier 
  stages 
  presents 
  the 
  usual 
  wavy 
  

   outline 
  which 
  I 
  referred 
  to 
  just 
  now. 
  

  

  In 
  its 
  last 
  stage 
  the 
  female 
  is 
  enclosed 
  in 
  a 
  thick 
  coat 
  of 
  whitish-cottony 
  

   felted 
  fibre. 
  The 
  feet 
  and 
  antenna 
  are 
  only 
  to 
  be 
  made 
  out 
  after 
  prolonged 
  

   maceration 
  in 
  potash. 
  The 
  whole 
  mass 
  inside 
  the 
  felted 
  matter 
  is 
  dirty- 
  

   brown 
  in 
  colour, 
  leathery 
  in 
  texture, 
  preserving 
  the 
  acuminate 
  pear-shape 
  

   of 
  the 
  last 
  stage. 
  

  

  When 
  arrived 
  at 
  this 
  condition 
  the 
  insect 
  appears 
  on 
  leaves 
  of 
  Panax, 
  

   Rubus, 
  Coprosma, 
  etc., 
  like 
  splashes 
  of 
  birds' 
  dung, 
  giving 
  the 
  leaf 
  a 
  

   peculiarly 
  nasty 
  look. 
  

  

  I 
  have 
  not 
  found 
  the 
  male 
  insect.

  I 
  obtained 
  this 
  species 
  in 
  Auckland, 
  on 
  Geniostoma 
  ligustrifolium. 
  I 
  have 
  

   only 
  the 
  female, 
  in 
  one 
  stage. 
  The 
  body 
  is 
  very 
  much 
  more 
  elongated 
  than 
  

   in 
  the 
  last 
  species, 
  the 
  width 
  being 
  not 
  more 
  than 
  a 
  quarter 
  of 
  the 
  length 
  ; 
  

   the 
  edge 
  of 
  the 
  body 
  is, 
  as 
  usual, 
  wavy 
  ; 
  the 
  stigmatic 
  spines 
  very 
  pro- 
  

   minent. 
  

  

  The 
  antenna 
  and 
  feet 
  resemble 
  those 
  of 
  C. 
  perforatus, 
  but 
  I 
  can 
  detect 
  

   no 
  lower 
  digitules. 
  

  

  The 
  fringe, 
  which 
  disappears 
  in 
  Canada 
  balsam, 
  differs 
  from 
  that 
  of 
  

   C. 
  perforatus 
  in 
  the 
  absence 
  of 
  the 
  perforations 
  and 
  in 
  the 
  shape 
  of 
  the 
  

   segments. 
  Instead 
  of 
  the 
  perforations 
  there 
  seem 
  to 
  be 
  transverse 
  wrinkles, 
  

   and 
  the 
  segments 
  are 
  not 
  roundly 
  triangular 
  but 
  quadrate 
  outwardly, 
  their 
  

   inner 
  apices 
  pointed; 
  see 
  plate 
  VII., 
  fig. 
  lid. 
  The 
  remainder 
  of 
  the 
  test 
  is 
  

   divided 
  into 
  quadrangular 
  scales. 
  The 
  whole 
  test 
  is 
  extremely 
  delicate 
  and 
  

   transparent.

  Plate

  fig.

   I 
  have 
  this 
  species 
  from 
  Atherosperma 
  novcd-zealandice 
  . 
  The 
  female 
  is 
  

   brown, 
  oval, 
  about 
  -^ 
  inch 
  long, 
  the 
  edge 
  slightly 
  wavy. 
  The 
  antenna 
  are 
  

   thick, 
  with 
  seven 
  joints, 
  all 
  nearly 
  equal 
  in 
  length 
  ; 
  the 
  third 
  joint 
  is 
  some- 
  

   what 
  the 
  longest; 
  the 
  seventh 
  has 
  a 
  few 
  hahs;
