  Notes 
  : 
  This 
  species 
  is 
  near 
  Hem. 
  orlandi, 
  Leon., 
  from 
  which 
  it 
  can 
  readily 
  be 
  

   distinguished 
  by 
  the 
  following 
  characters. 
  It 
  has 
  glands 
  at 
  the 
  anterior 
  stigmata 
  

   and 
  the 
  glands 
  around 
  the 
  sexual 
  aperture 
  are 
  always 
  more 
  numerous 
  ; 
  there 
  are 
  

   present, 
  although 
  not 
  very 
  apparent, 
  a 
  second 
  pair 
  of 
  lobes, 
  and 
  further, 
  the 
  last 
  four 
  

   abdominal 
  segments 
  are 
  supplied 
  with 
  hairs, 
  not 
  only 
  the 
  last 
  two 
  as 
  is 
  the 
  case 
  in 
  

   Hem. 
  orlandi." 
  

  

  This 
  species 
  is 
  not 
  represented 
  in

  collection 
  and 
  although 
  a 
  thorough 
  search 
  

   has 
  been 
  made 
  around 
  Pretoria 
  it 
  has 
  not 
  been 
  found

  Scale 
  of 
  adult 
  5 
  elongate, 
  usually 
  narrowed 
  in 
  front 
  and 
  gradually 
  broadening 
  

   behind. 
  The 
  colour 
  is 
  very 
  variable, 
  but 
  often 
  orange-brown 
  to 
  dark 
  brown. 
  The 
  

   exuviae 
  are 
  terminal, 
  with 
  the 
  second 
  exuviae 
  covered. 
  The 
  female 
  scales 
  are 
  usually 
  

   ± 
  curved. 
  Ventral 
  scale 
  variable, 
  similar 
  to 
  those 
  of 
  Chionaspis 
  spp. 
  

  

  The 
  (J 
  puparium 
  is 
  similar 
  to 
  that 
  of 
  the 
  $, 
  but 
  smaller 
  and 
  narrower 
  ; 
  the 
  larval 
  

   exuviae 
  are 
  terminal. 
  The 
  posterior 
  part 
  of 
  the 
  puparium 
  is 
  often 
  separated 
  by 
  a 
  

   thin 
  transverse 
  band 
  of 
  secretion, 
  which 
  acts 
  as 
  a 
  hinge, 
  allowing 
  the 
  extremity 
  of 
  the 
  

   scale 
  to 
  be 
  raised 
  to 
  permit 
  the 
  adult 
  $ 
  to 
  emerge.
