  and 
  third 
  lobes 
  are 
  smaller 
  and 
  very 
  similar 
  to 
  each 
  other 
  in 
  shape, 
  the 
  second 
  being 
  

   the 
  larger 
  ; 
  each 
  is 
  rounded 
  at 
  apex, 
  bears 
  a 
  prominent 
  notch 
  on 
  the 
  lateral 
  side, 
  

   and 
  is 
  slightly 
  inclined 
  towards 
  the 
  apex 
  of 
  the 
  pygidium. 
  Laterad 
  of 
  the 
  third 
  

   lobes 
  there 
  are 
  several 
  sharp-pointed 
  processes 
  on 
  the 
  pygidial 
  margin. 
  There 
  are 
  

   six 
  club-shaped 
  paraphyses 
  resembling 
  those 
  in 
  Aspidiotus 
  maleollus, 
  Gr., 
  to 
  which 
  

   this 
  insect 
  bears 
  some 
  resemblance 
  ; 
  the 
  body, 
  however, 
  is 
  not 
  hammer-shaped, 
  

   nor 
  are 
  there 
  any 
  circumgenital 
  pores 
  ; 
  the 
  body 
  contains 
  larvae. 
  The 
  pairs 
  of 
  para- 
  

   physes 
  laterad 
  of 
  the 
  third 
  lobes 
  is 
  inconspicuous. 
  Between 
  the 
  median 
  lobes 
  there 
  

   is 
  a 
  distinct 
  chitinised 
  area 
  of 
  the 
  pygidium. 
  The 
  plates 
  are 
  inconspicuous 
  ; 
  there 
  

   is 
  a 
  short 
  plate 
  laterad 
  of 
  the 
  median 
  lobes 
  and 
  one 
  or 
  two 
  laterad 
  of 
  the 
  second 
  

   lobe. 
  Bands 
  of 
  minute 
  pores 
  run 
  cephalad 
  from 
  the 
  margin 
  of 
  the 
  pygidium. 
  Long 
  

   setae 
  are 
  arranged 
  as 
  follows 
  : 
  — 
  0, 
  2, 
  2, 
  2, 
  2, 
  increasing 
  in 
  length 
  cephalad. 
  

  

  On 
  stem 
  of 
  Cabbage 
  Palm 
  (Oreodoxa 
  oleracea) 
  ; 
  also 
  on 
  Royal 
  Palm 
  (Acalypha 
  sp.) 
  

   and 
  Broussonetia 
  papyrifera, 
  Vent. 
  

  

  On 
  Broussonetia 
  the 
  scales 
  have 
  the 
  exuviae 
  yellowish-brown 
  or 
  yellowish-green 
  

   in 
  colour.* 
  

  

  This 
  insect 
  falls 
  near 
  to 
  Pseudaonidia 
  lesser 
  ata, 
  de 
  Ch., 
  but 
  the 
  lobes 
  are 
  very 
  different 
  

   from 
  those 
  figured 
  by 
  Newstead 
  in 
  this 
  Bulletin 
  (iv, 
  p. 
  309). 
  It 
  is 
  without 
  the 
  

   plate-like 
  process 
  which 
  Newstead 
  figures 
  laterad 
  of 
  the 
  third 
  lobes, 
  having 
  two 
  setae 
  

   in 
  this 
  position.

  Scale 
  completely 
  concealed 
  underneath 
  bark 
  of 
  plant. 
  Adult 
  $ 
  slightly 
  longer 
  

   than 
  broad, 
  cephalic 
  extremity 
  flattened, 
  caudal 
  pointed. 
  Metathorax 
  and 
  first 
  

   and 
  second 
  abdominal 
  segments 
  distinctly 
  produced 
  laterally. 
  

  

  Female 
  on 
  slide 
  about 
  2 
  mm. 
  long. 
  Median 
  lobes 
  large, 
  rounded 
  at 
  apex, 
  with 
  

   a 
  distinct 
  notch 
  on 
  the 
  lateral 
  side. 
  The 
  second 
  and 
  third 
  lobes 
  are 
  much 
  smaller, 
  

   but 
  distinct, 
  rounded 
  on 
  mesal 
  side 
  and 
  at 
  apex, 
  prominently 
  notched 
  on 
  lateral 
  

   side 
  ; 
  the 
  notch 
  may 
  be 
  absent 
  in 
  the 
  case 
  of 
  the 
  second 
  lobe. 
  Pygidial 
  margin 
  

   laterad 
  of 
  the 
  third 
  lobes 
  with 
  numerous 
  prominent 
  tooth-like 
  processes. 
  Two 
  

   pairs 
  of 
  paraphyses, 
  a 
  long 
  pair 
  between 
  first 
  and 
  second 
  lobes, 
  and 
  a 
  pair 
  of 
  about 
  

   half 
  the 
  length 
  between 
  the 
  second 
  and 
  third 
  lobes. 
  The 
  apex 
  of 
  each 
  paraphysis 
  

   is 
  a 
  round 
  knob 
  which 
  stands 
  out 
  the 
  more 
  prominently 
  because 
  the 
  region 
  imme- 
  

   diately 
  caudad 
  of 
  it 
  is 
  more 
  feebly 
  chitinised. 
  A 
  long 
  seta 
  and 
  two 
  short 
  plates 
  

   between 
  the 
  second 
  and 
  third 
  lobes, 
  and 
  between 
  the 
  third 
  lobe 
  and 
  the 
  first 
  tooth- 
  

   like 
  process 
  ; 
  a 
  seta 
  between 
  first 
  and 
  second, 
  and 
  another 
  between 
  second 
  and 
  

   third 
  teeth. 
  Anterior 
  spiracles 
  with 
  about 
  11 
  parastigmatic 
  pores 
  ; 
  posterior 
  spiracles 
  

   without 
  such 
  pores. 
  Anus 
  narrow. 
  Circumgenital 
  pores 
  in 
  an 
  arch 
  round 
  the 
  

   vagina. 
  

  

  On 
  branches 
  of 
  an 
  undetermined 
  plant 
  (possibly 
  Acalypha 
  sp.). 
  

  

  The 
  insect 
  is 
  attacked 
  by 
  Hymenopterous 
  parasites, 
  whose 
  exit 
  holes 
  are 
  often 
  

   the 
  only 
  indication 
  of 
  the 
  presence 
  of 
  the 
  scale-insect. 
  This 
  species 
  falls 
  near 
  P. 
  clavi- 
  

   gera, 
  Ckll., 
  but 
  the 
  latter 
  has 
  three 
  pairs 
  of 
  paraphyses. 
  

  

  * 
  I 
  have 
  specimens 
  of 
  this 
  insect 
  also 
  from 
  Cuba, 
  and 
  in 
  these 
  the 
  parastigmatic 
  

   glands 
  number 
  from 
  ten 
  to 
  eleven. 
  The 
  unborn 
  young 
  have 
  a 
  prominent 
  pair 
  of 
  lobes, 
  

   each 
  with 
  two 
  notches 
  on 
  the 
  mesal 
  and 
  three 
  on 
  the 
  lateral 
  obliquity 
  near 
  the 
  apex 
  

   of 
  the 
  lobe.
