  Tlie 
  puparium 
  is 
  yellowish-brown 
  or 
  dirty 
  white, 
  flat, 
  roughly 
  pear- 
  

   shaped, 
  thin 
  in 
  texture. 
  The 
  discarded 
  pellicle 
  of 
  the 
  first 
  stage 
  occupies 
  

   the 
  broad 
  end 
  of 
  the 
  pear 
  ; 
  that 
  of 
  the 
  second 
  nearly 
  fills 
  the 
  puparium. 
  

   This 
  second 
  pellicle 
  is 
  different 
  in 
  shape 
  from 
  those 
  of 
  other 
  species. 
  

   Instead 
  of 
  being 
  oval 
  in 
  shape 
  with 
  a 
  regularly 
  curved 
  outline, 
  it 
  is 
  nearly 
  

   identical 
  with 
  the 
  form 
  of 
  the 
  adult 
  female. 
  Its 
  cephalic 
  and 
  thoracic 
  

   portions 
  are 
  very 
  large, 
  oval, 
  and 
  smooth 
  ; 
  at 
  the 
  point 
  corresponding 
  to 
  

   the 
  metathorax 
  are 
  two 
  prominent 
  lobes, 
  triangular, 
  with 
  rounded 
  angles, 
  

   the 
  apex 
  of 
  each 
  turned 
  slightly 
  outwards. 
  The 
  outhne 
  then 
  descends 
  with 
  

   three 
  or 
  four 
  other 
  smaller 
  lobes 
  to 
  the 
  extremity 
  of 
  the 
  abdomen. 
  Plate 
  

   VI., 
  fig. 
  lOi, 
  shows 
  the 
  appearance 
  of 
  this 
  pellicle. 
  

  

  The 
  adult 
  female 
  would 
  appear 
  to 
  be, 
  in 
  its 
  earlier 
  state, 
  as 
  large 
  as 
  the 
  

   second 
  pellicle, 
  that 
  is, 
  filling 
  the 
  puparium 
  or 
  nearly 
  so. 
  In 
  the 
  specimens 
  

   which 
  I 
  obtained 
  the 
  female 
  had 
  begun 
  in 
  every 
  instance 
  to 
  lay 
  her 
  eggs, 
  

   and 
  was 
  gradually 
  shrivelhng 
  up. 
  Her 
  appearance 
  is 
  shown 
  in 
  plate 
  VI., 
  

   fig. 
  10a. 
  It 
  will 
  be 
  seen 
  that 
  the 
  lobes 
  visible 
  in 
  the 
  pellicle 
  are 
  here 
  absent, 
  

   but 
  I 
  am 
  not 
  sure 
  whether 
  this 
  is 
  not 
  the 
  effect 
  of 
  the 
  shrivelling 
  of 
  the 
  

   body. 
  

  

  The 
  cephalic 
  region 
  is 
  still 
  proportionately 
  very 
  large. 
  The 
  abdomen 
  is 
  

   conical, 
  the 
  sides 
  broken 
  to 
  within 
  a 
  short 
  distance 
  of 
  the 
  extremity 
  by 
  

   sharp 
  serrations, 
  between 
  which 
  are 
  triangular 
  scaly 
  hairs. 
  There 
  are 
  no 
  

   groups 
  of 
  spinnerets, 
  and 
  only 
  a 
  few 
  scattered 
  single 
  ones. 
  

  

  The 
  puparium 
  of 
  the 
  male 
  is 
  long, 
  narrow, 
  whitish, 
  and 
  with 
  the 
  

   appearance 
  of 
  a 
  semi-cylinder 
  lying 
  upon 
  a 
  plane 
  base. 
  The 
  perfect 
  insect, 
  

   in 
  general 
  appearance, 
  resembles 
  the 
  male 
  of 
  Diasjns 
  hoisduvalii 
  ; 
  but 
  the 
  

   abdomen 
  is 
  not 
  nearly 
  so 
  long, 
  and 
  the 
  tubular 
  sheath 
  of 
  the 
  abdominal 
  

   spike 
  is 
  much 
  smaller, 
  being 
  nearly 
  globular. 
  The 
  antennae 
  are 
  much 
  the 
  

   same 
  as 
  in 
  D. 
  hoisduvalii. 
  The 
  thoracic 
  band 
  occupies 
  about 
  half 
  the 
  width. 
  

  

  This 
  species 
  appears 
  to 
  be 
  very 
  subject 
  to 
  fungoid 
  growth. 
  In 
  dealing 
  

   with 
  the 
  succeeding 
  families 
  of 
  Lecanidse 
  and 
  Coccidse, 
  we 
  shall 
  find 
  that 
  

   very 
  many 
  of 
  their 
  species 
  are 
  subject 
  to 
  fungus 
  ; 
  but 
  in 
  the 
  Diaspid^, 
  so 
  

   far 
  as 
  I 
  have 
  been 
  able 
  to 
  observe, 
  this 
  is 
  not 
  the 
  case. 
  Diaspis 
  gigas, 
  how- 
  

   ever, 
  on 
  the 
  branch 
  of 
  Atlierospernia, 
  which 
  I 
  received, 
  was 
  in 
  several 
  

   instances 
  entirely 
  overgrown 
  by 
  a 
  fungus 
  which 
  appeared 
  to 
  me 
  to 
  belong 
  

   to 
  the 
  Physomycetous 
  Order 
  and 
  family 
  Antennariei. 
  In 
  one 
  instance 
  this 
  

   growth, 
  which 
  was 
  clearly 
  attached 
  to 
  the 
  puparium, 
  extended 
  nearly 
  an 
  

   inch 
  in 
  every 
  direction 
  round 
  it.

  On 
  the 
  same 
  tree, 
  Atherosperma, 
  I 
  found 
  a 
  Diasjns 
  which 
  may 
  perhaps 
  

  

  hQ 
  an 
  abnormal 
  form 
  of 
  the 
  last 
  species, 
  perhaps 
  distinct.
