  which 
  distinguish 
  it 
  from" 
  the 
  next 
  genus 
  which 
  has 
  but 
  two 
  or 
  three 
  rows, 
  

   and 
  from 
  the 
  European 
  species 
  which 
  has 
  six. 
  Besides 
  these 
  there 
  are 
  a 
  

   number 
  of 
  spinnerets 
  secreting 
  the 
  cottony 
  meal, 
  and 
  many 
  of 
  tliese 
  protrude 
  

   as 
  tubes 
  of 
  pecuhar 
  shape, 
  as 
  shown 
  in 
  fig. 
  18rf. 
  Tlie 
  antenna, 
  fig. 
  18^, 
  have 
  

   six 
  joints, 
  the 
  third 
  the 
  longest, 
  the 
  fourth 
  and 
  fifth 
  equal 
  to 
  each 
  other 
  and 
  

   nearly 
  round. 
  The 
  legs 
  have 
  the 
  tibia 
  somewhat 
  shorter 
  than 
  the 
  tarsus, 
  

   the 
  upper 
  digitules 
  are 
  pretty 
  long, 
  the 
  lower 
  only 
  short 
  hairs. 
  

  

  The 
  male 
  insect 
  is 
  orange 
  red, 
  with 
  long 
  wings, 
  undergoing 
  its 
  trans- 
  

   formations 
  in 
  a 
  sac 
  resembling 
  that 
  of 
  the 
  female. 
  The 
  antenucE 
  have 
  ten 
  

   joints, 
  of 
  which 
  the 
  fourth, 
  fifth, 
  sixth, 
  and 
  seventh 
  are 
  long 
  ; 
  the 
  second, 
  

   third, 
  eighth, 
  and 
  ninth 
  wider 
  and 
  globular 
  ; 
  the 
  tenth 
  globular 
  but 
  smaller. 
  

   The 
  hook 
  of 
  the 
  foot 
  is 
  long 
  ; 
  the 
  abdominal 
  spike, 
  fig. 
  18/, 
  is 
  short 
  and 
  

   thick, 
  with 
  a 
  curved 
  appendage. 
  

  

  II. 
  — 
  Eriococcus, 
  Targioni. 
  

  

  This 
  subdivision 
  also 
  has 
  a 
  sac, 
  but 
  it 
  is 
  usually 
  less 
  elongated 
  than 
  in 
  

   the 
  last, 
  and 
  white 
  in 
  colour. 
  My 
  species, 
  to 
  which 
  I 
  give 
  the 
  name 
  of 
  

  

  Eriococcus 
  araucaria, 
  sp. 
  nov. 
  (?) 
  

   is 
  found 
  on 
  the 
  Norfolk 
  Island 
  ^Dine 
  at 
  Governor's 
  Bay, 
  but 
  I 
  am 
  by 
  no 
  

   means 
  certain 
  that 
  it 
  is 
  indigenous. 
  The 
  female 
  insect 
  differs 
  from 
  the 
  last 
  

   described 
  only 
  in 
  the 
  number 
  of 
  the 
  conical 
  spines, 
  of 
  which 
  there 
  is 
  usually 
  

   only 
  one 
  row 
  round 
  the 
  edge, 
  though 
  in 
  some 
  specimens 
  a 
  few 
  scattered 
  

   spines 
  may 
  be 
  seen 
  elsewhere. 
  It 
  appears 
  to 
  resemble 
  greatly 
  E. 
  biixi, 
  

   Signoret, 
  and 
  I 
  doubt 
  whether 
  it 
  is 
  a 
  new 
  species 
  ; 
  at 
  the 
  same 
  time, 
  the 
  

   anal 
  hairs 
  are 
  only 
  six 
  in 
  number 
  as 
  against 
  eight 
  in 
  E. 
  buxi, 
  and 
  the 
  lower 
  

   digitules 
  appear 
  to 
  be 
  much 
  smaller. 
  I 
  therefore 
  provisionally 
  consider 
  it 
  

   a 
  distinct 
  species. 
  

  

  I 
  have 
  a 
  specimen 
  of 
  the 
  male, 
  not 
  in 
  its 
  perfect 
  state 
  but 
  as 
  a 
  pupa 
  

   upon 
  the 
  point 
  of 
  undergoing 
  transformation. 
  It 
  appears 
  to 
  differ 
  some- 
  

   what 
  from 
  that 
  of 
  Acanthococcus, 
  but 
  I 
  am 
  unable 
  to 
  say 
  how 
  far 
  it 
  differs 
  

  

  from 
  E. 
  buxi, 
  

  

  III. 
  — 
  Dactylopius, 
  Signoret. 
  

  

  The 
  females 
  of 
  this 
  subdivision 
  have 
  eight-jointed 
  antenna, 
  the 
  anal 
  

   tubercles 
  less 
  prominent 
  than 
  in 
  the 
  two 
  foregoing, 
  and 
  usually 
  a 
  series 
  of 
  

   cottony 
  appendages 
  running 
  all 
  round 
  the 
  edge 
  ef 
  the 
  body, 
  increasing 
  in 
  

   length 
  at 
  the 
  posterior 
  end. 
  

  

  The 
  differences 
  between 
  my 
  species 
  and 
  those 
  described 
  in 
  Europe 
  are 
  

   not, 
  in 
  some 
  cases, 
  great, 
  yet 
  they 
  are 
  such 
  as 
  induce 
  me 
  to 
  set 
  down 
  my 
  

   New 
  Zealand 
  specimens 
  as 
  distinct 
  species. 
  

  

  Dactylopius 
  calceolaria, 
  sp. 
  nov. 
  (?) 
  

  

  Plate 
  VIII., 
  fig. 
  19. 
  

  

  This 
  insect 
  is 
  effecting 
  great 
  destruction 
  in 
  the 
  public 
  gardens 
  in 
  Christ^ 
  

   eliurch 
  amongst 
  the 
  calceolarias, 
  and 
  upon 
  several 
  native 
  plants 
  such 
  as
