  on

  the 
  Circars

  the 
  

   cold 
  weather,

  on 
  red

  and 
  castor 
  

   during 
  the 
  cold 
  weather. 
  

  

  I 
  have 
  thus 
  tried 
  to 
  give 
  an 
  idea, 
  however 
  incomplete, 
  of 
  the 
  periodical 
  

   occurrences 
  of 
  the 
  most 
  important 
  insect 
  pests 
  of 
  South 
  India 
  by 
  dividing 
  

   them 
  into 
  three 
  more 
  or 
  less 
  convenient 
  groups, 
  and 
  I 
  have 
  attempted 
  

   to 
  convey 
  as 
  much 
  information 
  as 
  possible 
  in 
  the 
  diagrams 
  which 
  illus- 
  

   trate 
  this 
  paper. 
  I 
  believe, 
  as 
  our 
  knowledge 
  and 
  experience 
  increase, 
  

   it 
  might 
  be 
  possible 
  to 
  amend 
  this 
  calendar 
  in 
  the 
  light 
  of 
  new 
  observa- 
  

   tions, 
  and 
  make 
  it 
  far 
  more 
  accurate 
  and 
  complete 
  than 
  it 
  is 
  at 
  present. 
  

   Till 
  then 
  I 
  venture 
  to 
  believe 
  that 
  this 
  calendar 
  might 
  serve 
  some 
  useful 
  

   purpose. 
  

  

  In 
  conclusion, 
  I 
  am 
  of 
  opinion 
  that 
  if 
  such 
  calendars 
  are 
  prepared 
  for 
  

   the 
  different 
  provinces 
  they 
  will 
  be 
  found 
  not 
  only 
  useful 
  in 
  themselves, 
  

   but, 
  taken 
  as 
  a 
  whole, 
  will 
  give 
  one 
  a 
  fund 
  of 
  information 
  on 
  the 
  distribu- 
  

   tion, 
  seasonal 
  variation 
  aud 
  food 
  habits 
  of 
  some 
  of 
  the 
  important 
  crop- 
  

   pests 
  which 
  are 
  common 
  to 
  all 
  tracts 
  of 
  the 
  Indian 
  Empire.
