  Genus 
  BaccaCQGCUS, 
  nov. 
  

  

  Allied 
  to 
  the 
  Lecaniinae. 
  Body 
  of 
  adult 
  9, 
  at 
  maturity, 
  naked, 
  without 
  test 
  or 
  

   waxy 
  covering, 
  almost 
  globular, 
  appearing 
  like 
  a 
  berry 
  on 
  the 
  twigs 
  of 
  the 
  host- 
  

   plant. 
  In 
  the 
  type 
  species 
  the 
  colour 
  is 
  yellow 
  to 
  orange, 
  often 
  with 
  a 
  faint 
  

   metallic 
  bronzy 
  sheen, 
  the 
  whole 
  insect 
  simulating 
  a 
  Margarodes 
  cyst.

   well-develoved, 
  7-jointed. 
  Legs 
  well-developed, 
  long,

  Adult 
  female 
  almost 
  globular, 
  to 
  3 
  mm. 
  in 
  diameter, 
  yellow 
  to 
  brownish, 
  glossy, 
  

   like 
  a 
  Margarodes 
  cyst, 
  with 
  the 
  small 
  brown 
  anal 
  plates 
  occupying 
  the 
  position 
  of 
  

   the 
  caudal 
  pore 
  of 
  an 
  Asterolecanium 
  test. 
  In 
  the 
  middle 
  of 
  the 
  dorsum 
  there 
  is 
  a 
  

   prominence, 
  like 
  a 
  minute 
  keel, 
  occasionally 
  with 
  two 
  rounded 
  prominences 
  in 
  close 
  

   proximity 
  but 
  a 
  little 
  posterior 
  to 
  it. 
  There 
  is 
  no 
  fringe 
  in 
  the 
  material 
  at 
  hand, 
  

   but 
  four 
  short 
  white 
  bands, 
  two 
  on 
  either 
  side 
  from 
  the 
  stigmatic 
  clefts 
  at 
  the 
  point 
  

   where 
  the 
  insect 
  is 
  attached 
  to 
  the 
  thin 
  twig 
  or 
  leaf 
  of 
  the 
  host-plant. 
  

  

  When 
  cleared 
  and 
  mounted 
  the 
  derm 
  is 
  almost 
  hyaline, 
  appearing 
  yellowish, 
  

   with 
  the 
  antennae 
  and 
  legs 
  of 
  about 
  the 
  same 
  density. 
  The 
  integument 
  is 
  without 
  

   gland-pores 
  and 
  hairs 
  except 
  immediately 
  around 
  the 
  anal 
  plates
