  Aspidiotus 
  (Pseudaonidia) 
  trilobitijormis, 
  Green. 
  Occasionally 
  met 
  with 
  ; 
  this 
  

   Coccid 
  has 
  a 
  variety 
  of 
  hosts. 
  

  

  Cerataphis 
  lataniae, 
  Licht. 
  This 
  is 
  another 
  of 
  the 
  commonest 
  citrus 
  pests 
  ; 
  the 
  

   leaves 
  of 
  many 
  trees 
  both 
  old 
  and 
  young 
  were 
  found 
  to 
  be 
  heavily 
  infested. 
  This 
  

   Aphid 
  is 
  also 
  abundant 
  on 
  many 
  varieties 
  of 
  ornamental 
  palms. 
  

  

  Aphis 
  tavaresi, 
  del 
  G. 
  The 
  black 
  cotton 
  aphis 
  is 
  extremely 
  seasonal 
  in 
  its 
  

   occurrence 
  and 
  is 
  generally 
  found 
  on 
  the 
  leaves 
  and 
  young 
  tender 
  shoots. 
  

  

  Lepidoptera. 
  

  

  Argyroploce 
  leucotrsta, 
  Meyr. 
  (Citrus 
  Codling 
  Moth). 
  Larvae 
  have 
  been 
  found 
  

   on 
  several 
  occasions 
  in 
  mandarins, 
  but 
  not 
  in 
  oranges. 
  

  

  Papilio 
  demodocus, 
  Esp. 
  A 
  very 
  common 
  pest 
  on 
  all 
  young 
  citrus 
  trees. 
  Many 
  

   young 
  plants 
  are 
  completely 
  defoliated, 
  and 
  the 
  larvae 
  are 
  occasionally 
  found 
  feeding 
  

   on 
  tender 
  shoots 
  of 
  mature 
  trees. 
  

  

  Coleoptera. 
  

  

  Tragocephala 
  variegata, 
  Bert. 
  The 
  habits 
  of 
  this 
  Longicorn 
  have 
  been 
  described 
  

   under 
  pests 
  of 
  the 
  pigeon 
  pea. 
  It 
  attacks 
  all 
  varieties 
  of 
  Citrus. 
  

  

  Porphyronota 
  maculatissima, 
  Boh. 
  A 
  few 
  adults 
  of 
  this 
  unimportant 
  Cetoniid 
  

   beetle 
  have 
  been 
  taken 
  from 
  time 
  to

  feeding 
  on 
  the 
  leaves. 
  

  

  Gypmychus 
  cervinus, 
  Gerst. 
  A 
  number 
  of 
  adults 
  of 
  this 
  weevil 
  have 
  been 
  

   obtained, 
  they 
  attacked 
  the 
  leaves 
  of 
  young 
  orange 
  trees 
  ;

  Ceratitis 
  capitata, 
  Wd. 
  This 
  serious 
  pest 
  does 
  not 
  seem 
  to 
  be 
  very 
  widespread. 
  

   Oranges 
  and 
  mandarins 
  of 
  imported 
  varieties 
  were 
  found 
  to 
  be 
  infested, 
  but 
  

   indigenous 
  trees 
  (oranges, 
  mandarins 
  and 
  lemons) 
  are 
  far 
  less 
  susceptible 
  to 
  the 
  

   attacks 
  of 
  this 
  fruit-fly.

  Of 
  these 
  the 
  only

  of 
  importance 
  is
