  Asterolecanium 
  borboniae, 
  sp. 
  n. 
  (Plate

  fig. 
  198). 
  

  

  Test 
  of 
  adult 
  $ 
  small, 
  about 
  1 
  mm. 
  long 
  and 
  0'75 
  mm. 
  broad, 
  rounded 
  in 
  front 
  and 
  

   rather 
  pointed 
  behind, 
  slightly 
  convex, 
  with 
  the 
  margin 
  rather 
  thickened 
  and 
  slightly 
  

   crenulate. 
  The 
  extreme 
  posterior 
  extremity 
  appears 
  tubular 
  and 
  is 
  upturned 
  or 
  

   recurved 
  over 
  the 
  back. 
  There 
  is 
  apparently 
  no 
  marginal 
  or 
  dorsal 
  fringe. 
  The 
  

   colour 
  is 
  pale 
  greenish 
  yellow 
  and 
  the 
  test 
  is 
  almost 
  transparent, 
  showing 
  the 
  dark 
  

   body 
  of 
  the 
  female 
  at 
  the 
  anterior 
  end. 
  

  

  When 
  mounted 
  the 
  body 
  is 
  broad 
  pear-shaped, 
  about 
  0'9 
  mm. 
  long 
  and 
  0*6 
  mm. 
  at 
  

   greatest 
  width, 
  with 
  the 
  posterior 
  extremity 
  slightly 
  produced 
  and 
  broadly 
  rounded. 
  

   The 
  characters 
  are 
  very 
  indistinct. 
  The 
  anal 
  ring 
  is 
  small 
  ; 
  the 
  caudal 
  setae 
  stout, 
  

   about 
  65 
  to 
  70w 
  long, 
  and 
  the 
  margin 
  has 
  but 
  a 
  single 
  row 
  of 
  figure-8 
  glands, 
  which 
  

   are 
  small, 
  measuring 
  approximately 
  8/i 
  across 
  the 
  pair. 
  They 
  are 
  rather 
  wide 
  apart 
  

   (about 
  30/j) 
  and 
  are 
  not 
  associated 
  with 
  simple 
  glands 
  (fig. 
  189). 
  The 
  mouth-parts, 
  

   with 
  the 
  rostral 
  loop, 
  average 
  about 
  185,a 
  long. 
  

  

  A 
  (J 
  mounted 
  on 
  the 
  type 
  slide 
  from 
  the 
  Cape 
  collection, 
  measures 
  0*77 
  mm. 
  long 
  

   without 
  the 
  antennae 
  and 
  genital 
  spike. 
  The 
  latter 
  is 
  broad 
  and 
  strong 
  and 
  measures 
  

   150w. 
  The 
  antennae 
  are 
  10-jointed, 
  measuring 
  approximately

  Test 
  of 
  adult 
  $ 
  about 
  2 
  mm. 
  long 
  and 
  almost 
  as 
  broad, 
  nearly 
  circular, 
  with 
  the 
  

   posterior 
  extremity 
  slightly 
  produced. 
  Dorsum 
  convex, 
  with 
  a 
  rather 
  conspicuous 
  

   rounded 
  median 
  ridge, 
  but 
  without 
  transverse 
  ridges. 
  When 
  young 
  the 
  test 
  is 
  flat 
  

   and 
  entirely 
  covered 
  with 
  pinkish 
  filaments, 
  which 
  appear 
  to 
  be 
  divided 
  on 
  the 
  

   marginal 
  area. 
  When 
  a 
  little 
  older 
  the 
  dorsal 
  filaments 
  are 
  missing, 
  but 
  there 
  is 
  a 
  

   distinct 
  marginal 
  fringe 
  of 
  rather 
  long 
  pink 
  processes. 
  When 
  full-grown 
  the 
  

   marginal 
  fringe 
  also 
  is 
  usually 
  lacking. 
  The 
  colour 
  of 
  the 
  test 
  is 
  greenish 
  yellow, 
  

   except 
  when 
  it 
  contains 
  the 
  shrivelled 
  female 
  or 
  eggs, 
  which 
  show 
  through 
  the 
  semi- 
  

   transparent 
  test. 
  On 
  apple 
  the 
  insects 
  do 
  not 
  make 
  pits 
  in 
  the 
  bark, 
  nor 
  is 
  there 
  a 
  

   ridge 
  around 
  them. 
  Marginal 
  row 
  of 
  figure-8 
  glands 
  single, 
  with 
  the 
  addition 
  of 
  a 
  

   single 
  row 
  of 
  simple 
  glands. 
  

  

  The 
  figure-8 
  glands 
  are 
  of 
  two 
  sizes 
  and 
  are 
  scattered 
  over 
  the 
  body 
  surface 
  ; 
  the 
  

   smaller 
  are 
  about 
  equal 
  to 
  the 
  marginal 
  series 
  in 
  size, 
  the 
  others 
  almost 
  twice 
  as 
  large 
  

   (fig. 
  200 
  a). 
  Antennal 
  tubercles 
  prominent, 
  with 
  two 
  curved 
  spines 
  and 
  a 
  minute 
  spur 
  

   (fig. 
  200 
  6). 
  Caudal 
  lobes 
  moderately 
  prominent. 
  Caudal 
  setae 
  75,a. 
  Anal 
  setae 
  40/i.
