  — 
  On 
  some 
  Coccidte 
  in 
  New 
  Zealand, 
  195 
  

  

  The 
  adnlt 
  female 
  is 
  deeply 
  corrugated 
  except 
  (as 
  in 
  every 
  Mytilanpis) 
  on 
  

   the 
  cephalic 
  portion. 
  The 
  corrugations 
  bear 
  a 
  few 
  strong 
  spiny 
  hairs. 
  

   The 
  abdominal 
  pygidium 
  shows 
  an 
  almost 
  continuous 
  arch 
  of 
  spinnerets 
  

   over 
  the 
  anal 
  orifice. 
  In 
  Mytilaspis 
  huxi 
  the 
  groups 
  are 
  distinct. 
  The 
  

   spinnerets 
  of 
  Mytilasjns 
  jyyriformis 
  run 
  in 
  a 
  double 
  ring 
  round 
  the 
  anus, 
  

   with 
  here 
  and 
  there 
  an 
  outlying 
  opening. 
  Altogether 
  there 
  may 
  be 
  from 
  

   60 
  to 
  70 
  openings 
  in 
  the 
  arch. 
  There 
  are 
  many 
  single 
  spinnerets 
  scat- 
  

   tered 
  about, 
  a 
  large 
  number 
  of 
  them 
  more 
  or 
  less 
  oblong 
  ; 
  and 
  they 
  may 
  

   be 
  traced 
  up 
  the 
  sides 
  of 
  the 
  body 
  as 
  far 
  as 
  the 
  corrugations 
  extend. 
  

   Plate 
  v., 
  figs. 
  Sb 
  and 
  c, 
  show 
  the 
  appearance 
  of 
  the 
  female 
  and 
  the 
  arrange- 
  

   ment 
  of 
  the 
  spinnerets. 
  

  

  The 
  abdomen, 
  including 
  all 
  that 
  is 
  tinted 
  yellow, 
  does 
  not 
  show 
  a 
  con- 
  

   tinuously 
  curved 
  outline. 
  On 
  each 
  side, 
  next 
  to 
  the 
  last 
  corrugation 
  of 
  the 
  

   body, 
  is 
  a 
  large 
  triangular 
  lobe, 
  the 
  apex 
  furnished 
  with 
  scaly, 
  triangular, 
  

   serrated 
  hairs. 
  The 
  rest 
  of 
  the 
  abdomen 
  shows 
  a 
  curve 
  broken 
  by 
  small 
  

   lobes, 
  of 
  which 
  the 
  two 
  middle 
  ones 
  are 
  the 
  largest, 
  the 
  next 
  two 
  on 
  each 
  

   side 
  smaller, 
  and 
  the 
  rest 
  inconspicuous. 
  Between 
  the 
  lobes 
  are 
  scaly 
  hairs, 
  

   and 
  near 
  the 
  edge 
  runs 
  a 
  row 
  of 
  large 
  oblong 
  openings. 
  

  

  I 
  have 
  a 
  specimen 
  of 
  a 
  scale 
  from 
  Dysoxylum 
  spectabile, 
  which 
  seems 
  to 
  

   resemble 
  much 
  more 
  nearly 
  Mytilaspis 
  huxi; 
  and 
  this 
  is 
  not 
  unlikely, 
  as 
  the 
  

   specimen 
  came 
  from 
  a 
  greenhouse.

  This 
  scale, 
  which 
  appears 
  to 
  be 
  also 
  new, 
  I 
  have 
  found 
  on 
  a 
  great 
  

   number 
  of 
  New 
  Zealand 
  plants, 
  such 
  as 
  Cordyline, 
  Asjjleniuvi, 
  Phormium, 
  

   Gahnia, 
  Drimys, 
  Astelia, 
  and 
  many 
  others. 
  I 
  have 
  also 
  seen 
  it 
  on 
  Eucalyptus 
  

   globulus, 
  but 
  only 
  in 
  the 
  vicinity 
  of 
  New 
  Zealand 
  trees. 
  It 
  is 
  perhaps 
  more 
  

   abundant 
  on 
  the 
  cabbage 
  tree 
  than 
  on 
  others 
  ; 
  hence 
  I 
  have 
  named 
  it 
  as 
  

   above. 
  

  

  The 
  puparium 
  is 
  very 
  long 
  and 
  narrow, 
  generally 
  straight, 
  sometimes 
  

   curved, 
  semi- 
  cylindrical. 
  Length 
  about 
  -I 
  inch 
  ; 
  breadth 
  -^ 
  inch. 
  Colour 
  

   pure 
  white, 
  except 
  at 
  the 
  end 
  where 
  the 
  discarded 
  tests 
  are 
  ; 
  these 
  are 
  

   bright 
  yellow. 
  The 
  tests 
  are 
  oval 
  ; 
  the 
  second 
  more 
  elongated 
  than 
  the 
  

   first, 
  and 
  the 
  two 
  together 
  generally 
  occupy 
  rather 
  more 
  than 
  a 
  quarter 
  of 
  

   the 
  length 
  of 
  the 
  puparium. 
  The 
  eggs 
  are 
  small, 
  oval, 
  and 
  of 
  a 
  bright 
  

   yellow 
  colour. 
  

  

  The 
  adult 
  female 
  is 
  pale 
  golden, 
  about 
  three 
  times 
  as 
  long 
  as 
  broad 
  ; 
  the 
  

   cephalic 
  end 
  a 
  little 
  flattened 
  anteriorly, 
  and 
  above 
  the 
  rostrum 
  are 
  often 
  

   seen 
  the 
  two 
  minute 
  hairy 
  protuberances 
  called 
  rudimentary 
  antennae. 
  The 
  

   body 
  is 
  somewhat 
  corrugated, 
  but 
  less 
  so 
  than 
  in 
  M. 
  j)07norum 
  ; 
  the 
  corruga- 
  

   tions 
  show 
  a 
  very 
  few 
  fine 
  hah's.
