  Recent 
  publications 
  on 
  Oriental 
  Coccidse 
  have 
  shown 
  how 
  our 
  

   knowledge 
  of 
  this 
  group 
  of 
  insects 
  has 
  increased 
  considerably 
  within 
  

   the 
  last 
  decade, 
  in 
  spite 
  of 
  the 
  fact 
  that 
  only 
  very 
  few 
  people 
  have 
  done 
  

   any 
  work 
  in 
  that 
  direction. 
  Apart 
  from 
  the 
  value 
  of 
  the 
  systematic 
  

   study 
  of 
  this 
  group 
  of 
  insects 
  to 
  Science, 
  both 
  Agricultural 
  Entomologists 
  

   and 
  enlightened 
  farmers 
  have 
  begun 
  to 
  realise 
  the 
  importance 
  of 
  scale 
  

   insects 
  from 
  an 
  economic 
  aspect 
  ; 
  this 
  will 
  be 
  realised 
  all 
  the 
  more 
  

   as 
  the 
  fruit 
  industry 
  develops 
  in 
  India, 
  since 
  many 
  Coccidse 
  are 
  pests 
  

   of 
  fruit 
  trees. 
  It 
  is 
  therefore 
  quite 
  likely 
  that 
  greater 
  attention 
  may 
  

   be 
  paid 
  to 
  these 
  insects 
  in 
  the 
  future. 
  In 
  the 
  course 
  of 
  my 
  studies 
  of 
  

   the 
  South 
  Indian 
  species 
  of 
  this 
  family 
  during 
  the 
  last 
  three 
  years 
  it 
  

   often 
  occurred 
  to 
  me 
  that 
  a 
  check 
  list 
  of 
  the 
  Indo-Ceylonese 
  forms 
  might 
  

   be 
  useful 
  in 
  various 
  ways 
  especially 
  to 
  workers 
  in 
  this 
  group 
  all 
  ovei 
  

   India 
  and 
  this 
  paper 
  is 
  an 
  attempt 
  in 
  that 
  direction. 
  No 
  pains 
  have 
  

   been 
  spared 
  to 
  make 
  the 
  list 
  as 
  up-to-date 
  as 
  possible 
  by 
  including 
  all 
  

   forms 
  recorded 
  or 
  noted 
  from 
  this 
  region 
  till 
  now 
  ; 
  but 
  all 
  the 
  same 
  it 
  

   is 
  inevitable 
  that 
  some 
  mistakes 
  or 
  defects 
  must 
  have 
  crept 
  in. 
  I 
  shall 
  

   be 
  very 
  glad 
  to 
  have 
  my 
  attention 
  called 
  to 
  any 
  omissions 
  that 
  may 
  be 
  

   found 
  out 
  by 
  other 
  workers 
  in 
  this 
  line. 
  

  

  The 
  geographical 
  area 
  which 
  this 
  list 
  is 
  intended 
  to 
  include 
  com- 
  

   prises 
  the 
  whole 
  of 
  British 
  India, 
  Burma 
  and 
  Ceylon. 
  

  

  In 
  this 
  connection 
  it 
  must 
  be 
  stated 
  that 
  no 
  one 
  has 
  contributed 
  

   to 
  our 
  knowledge 
  of 
  Oriental 
  Coccidse 
  as 
  much 
  as 
  Mr. 
  E. 
  E. 
  Green, 
  one 
  

   of 
  the 
  foremost 
  authorities 
  on 
  this 
  family 
  of 
  insects 
  ; 
  and 
  amateurs 
  like 
  

   me 
  working 
  on 
  this 
  group 
  in 
  India 
  owe 
  him 
  a 
  debt 
  of 
  gratitude 
  for 
  the 
  

   valuable 
  help 
  he 
  has 
  been 
  rendering 
  in 
  this 
  direction. 
  

  

  The 
  information 
  attempted 
  to 
  be 
  given 
  under 
  each 
  species 
  includes 
  

   one 
  or 
  two 
  important 
  references, 
  one 
  or 
  two 
  of 
  the 
  host 
  plants, 
  and 
  

   the 
  chief 
  localities 
  in 
  the 
  region 
  where 
  the 
  insect 
  was 
  noted 
  ; 
  under 
  

   none 
  of 
  these 
  heads 
  is 
  any 
  attempt 
  made 
  to 
  give 
  complete 
  information.
