  The 
  main 
  object 
  of 
  the 
  experiments 
  set 
  forth 
  in 
  this 
  paper 
  was 
  not 
  

   so 
  much 
  the 
  destruction 
  of 
  insect 
  or 
  fungus 
  pests, 
  as 
  an 
  attempt 
  to 
  

   feed 
  trees 
  and 
  shorten 
  their 
  dormant 
  period 
  by 
  spraying 
  with 
  nitrate 
  

   solution, 
  and 
  the 
  results, 
  from 
  this 
  point 
  of 
  view, 
  are 
  interesting. 
  

   The 
  solution 
  found 
  to 
  be 
  most 
  satisfactory 
  consisted 
  of 
  nitrate 
  of 
  soda 
  

   200 
  lb., 
  caustic 
  soda 
  25 
  lb., 
  water 
  200 
  gals. 
  The 
  result 
  was 
  to 
  force 
  

   the 
  dormant 
  buds 
  out 
  several 
  days 
  ahead 
  of 
  the 
  normal 
  opening 
  period, 
  

   and 
  the 
  apparent 
  strengthening 
  and 
  increase 
  of 
  vigour 
  of 
  the 
  trees 
  

   was 
  possibly 
  useful 
  in 
  enabling 
  them, 
  to 
  resist 
  the 
  attack 
  of 
  insect 
  and 
  

   fungus 
  pests.

  Oxyrhachys 
  tarandus 
  (Membracidae) 
  occurs 
  in 
  many 
  parts 
  of 
  India 
  

   and 
  is 
  w^idely 
  distributed 
  in 
  Africa. 
  Among 
  its 
  food-plants 
  are 
  Acacia 
  

   siamea, 
  A. 
  arabica, 
  and 
  Casuarina 
  sp., 
  reported 
  from 
  Madras 
  ; 
  Cassia 
  

   fistula 
  and 
  A. 
  arabica, 
  reported 
  from 
  Bihar 
  (Pusa) 
  ; 
  A. 
  catechu, 
  Albizzia 
  

   lebbeJc, 
  Albizzia 
  jprocera, 
  Phyllanthus 
  emblica, 
  Tamarindus 
  indica 
  and 
  

   Dalbergia 
  latifoUa, 
  from 
  Dehra 
  Dun 
  District. 
  Injury 
  is 
  caused 
  by 
  the 
  

   insertion 
  of 
  the 
  proboscis 
  into 
  the 
  young 
  stems 
  in 
  order 
  to 
  suck 
  sap, 
  

   and 
  to 
  a 
  greater 
  extent 
  by 
  the 
  incisions 
  made 
  by 
  the 
  saw-like 
  o\aposi- 
  

   tor 
  of 
  the 
  female 
  while 
  laying 
  her 
  eggs. 
  The 
  trees 
  attacked 
  become 
  

   stunted 
  and 
  more 
  exposed 
  to 
  the 
  attacks 
  of 
  other 
  insects. 
  The 
  eggs 
  

   are 
  laid 
  in 
  the 
  bark 
  of 
  the 
  young 
  shoot, 
  but 
  there 
  is 
  very 
  little 
  definite 
  

   information 
  as 
  to 
  the 
  length 
  of 
  the 
  life-cycle. 
  Descriptions 
  are 
  given 
  

   of 
  the 
  egg, 
  larva, 
  nymph 
  and 
  adult. 
  Until 
  the 
  life-history 
  of 
  this 
  

   insect 
  is 
  worked 
  out, 
  no 
  proper 
  remedies 
  can 
  be 
  laid 
  down. 
  In 
  small 
  

   nurseries 
  and 
  gardens 
  w^here 
  the 
  insect 
  is 
  abundant 
  the 
  following 
  meas- 
  

   ures 
  may 
  be 
  adopted 
  : 
  spraying 
  with 
  kerosene 
  and 
  soap 
  emulsion, 
  

   keeping 
  the 
  ground 
  between 
  the 
  trees 
  clean 
  and 
  constantly 
  ploughed, 
  

   and 
  handpicking. 
  The 
  eggs 
  of 
  0. 
  tarandus 
  have 
  been 
  found 
  para- 
  

   sitised 
  by 
  a 
  Chalcid.

  Pissodes 
  validirostris, 
  Gyl., 
  has 
  on 
  several 
  occasions 
  done 
  great 
  harm 
  

   to 
  fir-cones. 
  The 
  adult 
  makes 
  its 
  appearance 
  in 
  July 
  in 
  the 
  neigh- 
  

   bourhood 
  of 
  Stockholm 
  and 
  feeds 
  on 
  the 
  young 
  cones 
  ; 
  the 
  larva 
  

   hibernates 
  in 
  the 
  middle 
  of 
  the 
  cones 
  and 
  pupates 
  in 
  the 
  spring, 
  only 
  

   one 
  generation 
  occurring 
  a 
  year. 
  The 
  attacked 
  cones 
  are 
  easily 
  

   recognised 
  by 
  their 
  pale 
  brownish 
  yellow 
  colour,
