  Aonidiella 
  pothi, 
  sp. 
  nov. 
  

  

  Female 
  scale 
  of 
  a 
  very 
  dark 
  brown 
  colour 
  and 
  shining. 
  The 
  first 
  exuvium 
  has 
  a 
  

   reddish 
  tinge. 
  The 
  whole 
  scale 
  is 
  slightly 
  elongated, 
  with 
  the 
  exuviae 
  towards 
  

   one 
  end. 
  When 
  removed 
  a 
  faint 
  white 
  ventral 
  scale 
  is 
  left. 
  A 
  pair 
  of 
  short 
  club-shaped 
  

   paraphyses 
  between 
  the 
  first 
  and 
  second 
  lobes, 
  and 
  similar 
  paraphyses 
  more 
  or 
  

   less 
  distinct 
  between 
  second 
  and 
  third, 
  and 
  third 
  and 
  fourth 
  lobes. 
  Between 
  

   these 
  and 
  cephalad 
  of 
  the 
  median 
  lobes 
  there 
  is 
  a 
  chitinous 
  knob. 
  The 
  antenna 
  

   consists 
  of 
  a 
  tubercle 
  bearing 
  a 
  long 
  seta. 
  The 
  median 
  lobes 
  are 
  somewhat 
  

   triangular 
  in 
  shape, 
  with 
  a 
  distinct 
  point 
  at 
  apex 
  mesally, 
  sometimes 
  an 
  apical 
  

   notch, 
  a 
  notch 
  on 
  the 
  lateral 
  margin 
  near 
  apex 
  and 
  on 
  the 
  mesal 
  margin 
  

   near 
  the 
  base. 
  The 
  second 
  lobes 
  are 
  narrower 
  than 
  the 
  median, 
  longer 
  than 
  broad, 
  

   convergent 
  caudally, 
  pointed 
  or 
  rounded 
  at 
  apex, 
  with 
  the 
  lateral 
  margin 
  distinctly 
  

   notched. 
  The 
  third 
  lobes 
  are 
  as 
  broad 
  ds 
  long, 
  divergent 
  caudally, 
  notched 
  on 
  

   both 
  sides, 
  rounded 
  at 
  apex 
  ; 
  the 
  mesal 
  notch 
  is 
  sometimes 
  indistinct. 
  The 
  fourth 
  

   and 
  fifth 
  lobes 
  are 
  more 
  or 
  less 
  distinct, 
  triangular, 
  serrated, 
  the 
  pygidium 
  in 
  the 
  

   interval 
  between 
  them 
  also 
  being 
  serrated. 
  There 
  are 
  two 
  pectinae 
  between 
  the 
  

   median 
  lobes, 
  two 
  between 
  first 
  and 
  second 
  lobes, 
  three 
  between 
  second 
  and 
  third 
  

   lobes, 
  three 
  between 
  third 
  and 
  fourth 
  lobes 
  ; 
  all 
  are 
  shortly 
  three- 
  or 
  four-pronged 
  

   at 
  apex. 
  There 
  is 
  a 
  seta 
  laterad 
  of 
  the 
  mesal 
  lobes 
  ; 
  two 
  laterad 
  of 
  second 
  lobes, 
  one 
  

   being 
  on 
  base 
  of 
  lobe 
  ; 
  two 
  laterad 
  of 
  third 
  lobes, 
  one 
  being 
  on 
  the 
  lobe 
  ; 
  two 
  

   laterad 
  of 
  fourth 
  lobe, 
  one 
  being 
  on 
  the 
  lobe 
  ; 
  and 
  three 
  on 
  the 
  margin 
  of 
  the 
  

   pygidium 
  cephalad 
  of 
  fourth 
  lobe. 
  The 
  anus 
  is 
  longer 
  than 
  broad. 
  There 
  are 
  no 
  

   circumgenital 
  pores. 
  Plates 
  of 
  chitin 
  serrated 
  on 
  the 
  caudal 
  edge 
  surround 
  the 
  

   anterior 
  margin 
  of 
  the 
  vagina, 
  giving 
  a 
  faint 
  tessellated 
  appearance. 
  

  

  The 
  insects 
  contain 
  larvae 
  with 
  antennae, 
  legs, 
  mouth-parts 
  and 
  pygidial 
  lobes 
  

   well 
  developed 
  ; 
  the 
  lobes 
  are 
  two 
  in 
  number, 
  conspicuous, 
  produced 
  into 
  the 
  

   pygidium, 
  converging 
  caudally, 
  rounded 
  at 
  apex, 
  with 
  one 
  notch 
  on 
  the 
  mesal 
  and 
  

   two 
  on 
  the 
  lateral 
  side. 
  

  

  The 
  antennae 
  distad 
  of 
  the 
  fourth 
  segment 
  are 
  ringed 
  and 
  end 
  somewhat 
  abruptly. 
  

  

  On 
  Pothos 
  scandens, 
  chiefly 
  at 
  the 
  nodes 
  under 
  the 
  bud 
  scales 
  ; 
  also 
  on 
  

   Loranthus 
  sp. 
  

  

  This 
  insect 
  falls 
  near 
  Aspidiotus 
  glomeratus, 
  Gr., 
  from 
  which, 
  however, 
  it 
  is 
  quite 
  

   distinct. 
  

  

  Hemichionaspis 
  alatae, 
  sp. 
  nov. 
  

  

  Female 
  scale 
  very 
  inconspicuous, 
  about 
  3 
  mm. 
  long, 
  of 
  a 
  dull, 
  pale 
  brown 
  

   colour. 
  The 
  exuviae 
  are 
  situated 
  at 
  one 
  end 
  and 
  are 
  of 
  much 
  the 
  same 
  colour 
  as 
  

   the 
  rest 
  of 
  the 
  scale. 
  The 
  secretion 
  is 
  comparatively 
  broad. 
  The 
  second 
  exuvium 
  

   has 
  a 
  slight 
  but 
  distinct 
  median 
  longitudinal 
  ridge. 
  

  

  Male 
  scale 
  white, 
  tricarinate, 
  in 
  dense 
  clusters 
  and 
  lying 
  flat 
  on 
  the 
  twigs. 
  

  

  The 
  median 
  lobes 
  of 
  the 
  adult 
  female 
  are 
  large, 
  extending 
  slightly 
  caudad 
  of 
  

   second 
  lobes, 
  the 
  lateral 
  edges 
  sloping 
  away 
  to 
  the 
  pygidium 
  and 
  with 
  three 
  or 
  four 
  

   distinct 
  notches. 
  The 
  second 
  lobes 
  are 
  duplex, 
  feebly 
  chitinised 
  but 
  distinct, 
  each 
  

   half 
  expanded 
  towards 
  the 
  apex. 
  Third 
  lobe 
  sometimes 
  developed, 
  duplex, 
  mesal 
  

   half 
  longer 
  than 
  broad, 
  lateral 
  broader 
  than 
  long, 
  both 
  serrated 
  on 
  margin.
