  the

  abdomen 
  

   of

  This 
  species 
  is 
  found 
  on 
  the 
  roots 
  of 
  the 
  common 
  tussock 
  grass, 
  or 
  rather 
  

   on 
  the 
  stems 
  close 
  to 
  the 
  ground. 
  

  

  It 
  is 
  a 
  rather 
  large 
  insect, 
  bright 
  pink 
  in 
  colour, 
  covered 
  with 
  a 
  white 
  

   meal, 
  and 
  with 
  a 
  very 
  regular 
  oval 
  outline 
  ; 
  flat 
  on 
  the 
  underside, 
  convex 
  

   above. 
  The 
  mentum 
  has 
  a 
  few 
  hairs 
  at 
  the 
  tip 
  ; 
  the 
  setae 
  are 
  long. 
  

  

  The 
  antennae 
  are 
  very 
  short 
  ; 
  the 
  second 
  and 
  thii-d 
  joints 
  are 
  the 
  longest; 
  

   the 
  last 
  joint 
  has 
  a 
  few 
  hairs. 
  Fig. 
  l%e. 
  

  

  The 
  legs 
  are 
  short 
  ; 
  the 
  coxa 
  thick, 
  the 
  femur 
  somewhat 
  thinner, 
  the 
  

   tibiae 
  and 
  tarsus 
  still 
  less 
  and 
  about 
  equal 
  in 
  length. 
  The 
  upper 
  digitules, 
  

   fig. 
  19/, 
  are 
  not 
  long, 
  the 
  lower 
  inconspicuous, 
  if 
  not 
  wanting. 
  There 
  are 
  a 
  

   few 
  hairs 
  on 
  the 
  tarsus. 
  

  

  The 
  anal 
  tubercles 
  are 
  extremely 
  small, 
  scarcely 
  perceptible 
  ; 
  each 
  has 
  

   three 
  conical 
  spines 
  but 
  no 
  hairs, 
  and 
  a 
  few 
  other 
  spines 
  are 
  visible 
  on 
  the 
  

   abdomen. 
  The 
  anal 
  ring 
  has, 
  I 
  think, 
  six 
  hairs; 
  fig. 
  19^'. 
  AU 
  over 
  the 
  

   body 
  are 
  numbers 
  of 
  small 
  circular 
  spinnerets. 
  

  

  I 
  have 
  not 
  the 
  male 
  of 
  this 
  species, 
  which 
  is, 
  I 
  think, 
  certainly 
  new. 
  

  

  IV, 
  — 
  IcERYA, 
  Signoret, 
  

  

  My 
  specimens 
  of 
  this 
  subdivision 
  were 
  found 
  on 
  a 
  hedge 
  of 
  the 
  kangaroo 
  

   acacia, 
  in 
  Auckland, 
  in 
  March 
  last. 
  I 
  understood 
  from 
  Mr. 
  Cheeseman 
  

   and 
  Dr. 
  Purchas, 
  who 
  kindly 
  brought 
  the 
  insect 
  under 
  my 
  notice, 
  that 
  it 
  

   had 
  only 
  lately 
  appeared 
  in 
  Auckland, 
  and 
  that 
  it 
  was 
  only, 
  as 
  yet, 
  to 
  be 
  

   found 
  upon 
  that 
  one 
  hedge. 
  The 
  plants, 
  I 
  may 
  say, 
  were 
  nearly 
  destroyed 
  

   by 
  the 
  insects, 
  which 
  covered 
  them 
  in 
  great 
  numbers 
  ; 
  and 
  the 
  large 
  size 
  

   and 
  peculiar 
  appearance 
  of 
  the 
  pest 
  were 
  very 
  striking. 
  

  

  The 
  genus 
  Icerya 
  belongs 
  to 
  the 
  Monophlebidse, 
  a 
  family 
  of 
  Coccidse, 
  

   which 
  has 
  eleven 
  joints 
  in 
  the 
  antennae 
  of 
  the 
  female, 
  and 
  ten 
  in 
  the 
  

   antennas 
  of 
  the 
  male. 
  There 
  are 
  several 
  genera 
  of 
  these, 
  but 
  the 
  insect 
  

   before 
  me 
  seems 
  certainly 
  to 
  belong 
  .to 
  Icerya. 
  There 
  is 
  but 
  one 
  feature, 
  

   the 
  absence 
  of 
  which 
  in 
  my 
  species 
  may 
  perhaps 
  relegate 
  it 
  to 
  some 
  new 
  

   genus. 
  M. 
  Signoret 
  says 
  that, 
  after 
  treatment 
  with 
  potash, 
  a 
  tube 
  may 
  be 
  

   seen 
  above 
  the 
  anal 
  orifice 
  forming 
  a 
  sort 
  of 
  folded 
  ring 
  ; 
  this 
  tube 
  he 
  takes 
  

   to 
  be 
  the 
  o^^duct. 
  I 
  have 
  not 
  been 
  able 
  to 
  observe 
  this 
  tube 
  although 
  I 
  

   have 
  examined 
  several 
  specimens. 
  At 
  the 
  same 
  time 
  all 
  the 
  other 
  features 
  

   correspond 
  to 
  the 
  description 
  of 
  the 
  genus 
  Icerya 
  ; 
  and 
  I 
  am 
  not 
  inchned 
  

   to 
  attempt 
  the 
  formation 
  of 
  a 
  new 
  genus 
  simply 
  on 
  account 
  of 
  the 
  absence 
  

   of 
  a 
  feature 
  which 
  perhaps 
  I 
  ought 
  to 
  have 
  been 
  able 
  to 
  make 
  out.
