  Between 
  the 
  first 
  and 
  second 
  lobes 
  there 
  is 
  a 
  very 
  prominent 
  gland-pore 
  projection, 
  

   distinctly 
  longer 
  than 
  broad, 
  and 
  sometimes 
  projecting 
  further 
  caudad 
  than 
  the 
  

   second 
  lobe. 
  The 
  gland-pore 
  projections 
  laterad 
  of 
  the 
  second 
  lobes 
  are 
  also 
  con- 
  

   spicuous.

  There 
  is 
  a 
  small 
  seta 
  at 
  the 
  base 
  of 
  the 
  

   median 
  lobes, 
  and 
  a 
  larger 
  seta 
  laterad 
  of 
  them 
  ; 
  two 
  setae 
  connected 
  with 
  the 
  

   second 
  lobe, 
  and 
  two, 
  one 
  of 
  which 
  is 
  small, 
  connected 
  with 
  the 
  third 
  lobe 
  ; 
  one 
  

   laterad 
  of 
  the 
  two 
  gland-pore 
  projections 
  beyond 
  the 
  third 
  plate. 
  Dorsal 
  pores 
  

   few 
  but 
  large 
  and 
  oval. 
  Circumgenital 
  pores 
  (8-10) 
  (20-23) 
  (17-23). 
  

  

  Adult 
  (J 
  orange-red, 
  with 
  whitish 
  wings 
  ; 
  tarsus 
  shorter 
  than 
  tibia 
  and 
  with 
  

   two 
  digitules 
  ; 
  a 
  single 
  hair 
  at 
  the 
  apex 
  of 
  the 
  antenna. 
  

  

  On 
  branches 
  of 
  Carsia 
  alata. 
  

  

  It 
  is 
  subject 
  to 
  the 
  attack 
  of 
  Hymenopterous 
  parasites 
  and 
  is 
  preyed 
  on 
  by 
  

   Coccinellid 
  larvae. 
  

  

  This 
  insect 
  is 
  near 
  H. 
  minor, 
  Mask., 
  and 
  may 
  be 
  a 
  variety 
  of 
  that 
  insect. 
  

   H. 
  minor, 
  however, 
  has 
  " 
  female 
  puparium 
  white 
  " 
  (Maskell 
  ; 
  Cooley), 
  " 
  opaque 
  

   snowy 
  white, 
  often 
  specked 
  with 
  brown 
  " 
  (Green 
  — 
  Ch. 
  albizziae, 
  Gr.). 
  Further, 
  the 
  

   lateral 
  lobes 
  of 
  H. 
  minor 
  are 
  ordinarily 
  less 
  well 
  developed. 
  It 
  may 
  be 
  merely 
  a 
  

   variety 
  of 
  H. 
  aspidistrae, 
  Sign., 
  which 
  seems 
  to 
  be 
  a 
  very 
  variable 
  insect. 
  

  

  Chionaspis 
  malloti,

  Female 
  scale 
  more 
  or 
  less 
  circular, 
  convex, 
  covered 
  with 
  hairs 
  from 
  the 
  food- 
  

   plant. 
  Exuviae 
  eccentric, 
  covered 
  with 
  secretion 
  ; 
  when 
  rubbed 
  are 
  seen 
  to 
  be 
  

   of 
  a 
  light 
  orange-yellow 
  colour. 
  When 
  the 
  scale 
  is 
  removed 
  a 
  white 
  mark 
  is 
  left 
  on 
  

   the 
  twig. 
  No 
  exuviae 
  are 
  to 
  be 
  seen 
  from 
  the 
  ventral 
  surface, 
  being 
  hidden 
  under 
  

   a 
  covering 
  of 
  white 
  wax. 
  

  

  Male 
  scale 
  not 
  observed. 
  

  

  The 
  insect 
  when 
  treated 
  with 
  KOH 
  and 
  mounted 
  on 
  a 
  slide 
  is 
  slightly 
  longer 
  

   than 
  broad, 
  rounded 
  anteriorly 
  and 
  bluntly 
  pointed 
  posteriorly. 
  There 
  is 
  but 
  one 
  

   lobe, 
  evidently 
  formed 
  by 
  the 
  fusion 
  of 
  two. 
  This 
  lobe 
  is 
  very 
  prominent, 
  broader 
  

   than 
  long, 
  with 
  the 
  sides 
  parallel 
  at 
  base, 
  afterwards 
  converging, 
  giving 
  a 
  somewhat 
  

   triangular 
  shape 
  to 
  the 
  lobe 
  ; 
  rounded 
  at 
  apex, 
  with 
  a 
  short 
  median 
  basal 
  prolonga- 
  

   tion 
  into 
  the 
  pygidium 
  ; 
  with 
  two 
  large 
  setae 
  on 
  the 
  lobe 
  and 
  a 
  small 
  seta 
  

   immediately 
  laterad 
  of 
  the 
  lobe 
  on 
  each 
  side. 
  Laterad 
  of 
  median 
  lobe 
  is 
  a 
  short, 
  

   heavily 
  chitinised 
  incision, 
  the 
  two 
  sides 
  of 
  the 
  incision 
  being 
  fused. 
  Laterad 
  of 
  

   this 
  are 
  two 
  large 
  setae 
  and 
  a 
  cluster 
  of 
  some 
  eleven 
  long 
  plates. 
  Laterad 
  of 
  this 
  

   a 
  second 
  incision 
  with 
  a 
  minute 
  pointed 
  hyaline 
  lobe 
  and 
  a 
  group 
  of 
  two 
  long 
  setae 
  

   and 
  some 
  twelve 
  long 
  plates. 
  Laterad 
  of 
  this 
  a 
  third 
  incision 
  and 
  a 
  group 
  of 
  two 
  

   setae 
  and 
  some 
  eleven 
  plates. 
  Cephalad 
  of 
  this 
  are 
  four 
  groups 
  of 
  similar 
  plates 
  

   decreasing 
  in 
  size 
  towards 
  the 
  anterior 
  end. 
  Circumgenital 
  pores 
  in 
  five 
  groups 
  and 
  

   very 
  numerous, 
  at 
  least 
  100 
  in 
  the 
  median 
  group 
  ; 
  they 
  are 
  situated 
  in 
  groups 
  as 
  in 
  

   the 
  genus 
  Aulacaspis. 
  Cephalad, 
  mesad 
  and 
  caudad 
  of 
  the 
  circumgenital 
  pores 
  

   the 
  pygidium 
  is 
  more 
  heavily 
  chitinised. 
  Numerous 
  dorsal 
  pores 
  immediately 
  

   cephalad 
  of 
  third 
  and 
  fourth 
  groups 
  of 
  plates. 
  Antennae 
  widely 
  separated, 
  con- 
  

   sisting 
  of 
  two 
  long 
  spines 
  on 
  a 
  low 
  spinous 
  tubercle. 
  Anterior 
  and 
  posterior 
  spiracles 
  

   with 
  numerous 
  glands.
