  Peradeniya 
  on 
  the 
  10th 
  October. 
  By 
  the 
  6th 
  November 
  the 
  trees 
  were 
  

   heavily 
  infested 
  and 
  had 
  a 
  withered 
  appearance 
  due 
  to 
  the 
  dead 
  leaves. 
  

   A 
  month 
  later 
  only 
  a 
  few 
  withered 
  leaves 
  remained 
  on 
  the 
  tree, 
  and 
  

   neighbouring 
  trees 
  of 
  Funtumia, 
  that 
  had 
  up 
  till 
  then 
  remained 
  almost 
  

   free 
  from 
  attack, 
  were 
  beginning 
  to 
  show 
  here 
  and 
  there 
  a 
  withered 
  

   leaf. 
  This 
  afforded 
  an 
  object 
  lesson 
  of 
  the 
  consequence 
  of 
  neglecting 
  

   the 
  first 
  stages 
  of 
  an 
  attack. 
  Had 
  a 
  thorough 
  spraying 
  with 
  lead 
  

   arsenate, 
  at 
  a 
  strength 
  of 
  5 
  lb. 
  to 
  100 
  gals, 
  water, 
  been 
  undertaken 
  

   the 
  outbreak 
  would 
  probably 
  have 
  been 
  arrested. 
  Hampson 
  gives 
  

   the 
  distribution 
  as 
  Sikkim, 
  Assam, 
  Bombay, 
  Nilgiris, 
  Ceylon 
  and 
  

   Burma. 
  Green 
  records 
  the 
  larva 
  as 
  feeding 
  on 
  Portlandia 
  grandiflora 
  

   and 
  Holarrhena 
  mitis. 
  Neighbouring 
  trees 
  of 
  Funtumia 
  were 
  infested 
  

   with 
  Coccus 
  viridis, 
  and 
  the 
  leaves 
  were 
  covered 
  with 
  sooty 
  mould. 
  

   An 
  undetermined 
  Pyralid 
  larva 
  was 
  feeding 
  on 
  the 
  scales, 
  and 
  they 
  

   were 
  also 
  attacked 
  by 
  a 
  greyish 
  black 
  fungus. 
  Pulvinaria 
  sp. 
  was 
  

   also 
  present 
  on 
  the 
  leaves, 
  and 
  also 
  not 
  a 
  few 
  specimens 
  of 
  Lecanium 
  

   caudatum, 
  Gr. 
  

  

  Manihot 
  glaziovii 
  (Ceara 
  Rubber). 
  Beetles 
  were 
  found 
  boring 
  in 
  

   several 
  trees 
  that 
  had 
  had 
  their 
  bark 
  skinned 
  during 
  the 
  wet 
  weather 
  

   in 
  preparation 
  for 
  tapping. 
  One 
  is 
  probably 
  a 
  species 
  of 
  Xyleborus, 
  

   while 
  the 
  other 
  is 
  a 
  long-snouted, 
  slender, 
  dark-brown 
  weevil 
  about 
  

   4 
  '5 
  millimetres 
  long. 
  Saissetia 
  nigra 
  has 
  been 
  observed 
  on 
  the 
  leaves 
  

   of 
  M. 
  glaziovii. 
  

  

  Landolphia

  (African 
  Rubber). 
  A 
  plant 
  of 
  this 
  species 
  in 
  the 
  

   Botanic 
  Gardens 
  was 
  found 
  infested 
  with 
  Coccus 
  viridis, 
  Gr., 
  the 
  leaves 
  

   being 
  black 
  with 
  sooty 
  mould, 
  and 
  also 
  heavily 
  infested 
  on 
  their 
  under 
  

   surface 
  with 
  Ichnaspis 
  longirostris.

  At 
  the 
  end 
  of 
  this 
  paper 
  on 
  cacao 
  culture, 
  the 
  author 
  notes 
  that 
  a 
  

   severe 
  pest 
  of 
  this 
  plant 
  in 
  probably 
  all 
  provinces 
  of 
  the 
  PhiUppines, 
  

   is 
  the 
  branch-boring 
  beetle 
  [species 
  not 
  stated.] 
  The 
  grub 
  of 
  this 
  

   insect 
  bores 
  up 
  or 
  down 
  through 
  the 
  centre 
  of 
  the 
  branch 
  causing 
  very 
  

   severe 
  weakening 
  and 
  final 
  death 
  of 
  the 
  affected 
  portion. 
  Branches 
  

   suspected 
  of 
  containing 
  these 
  grubs, 
  i.e., 
  those 
  having 
  one 
  or 
  more 
  

   holes 
  in 
  the 
  bark 
  and 
  showing 
  a 
  weakened 
  condition 
  of 
  the 
  foliage, 
  

   should 
  be 
  removed 
  and 
  burned. 
  On 
  young 
  plants, 
  scale-insects, 
  

   aphis, 
  and 
  leaf-eating 
  beetles 
  sometimes 
  do 
  a 
  slight 
  amount 
  of 
  damage 
  

   but 
  can 
  be 
  easily 
  controlled.

  This 
  weevil 
  has 
  recently 
  been 
  reported 
  from 
  the 
  North 
  of 
  Scotland, 
  

   where 
  it 
  appears 
  to 
  be 
  more 
  widely 
  distributed 
  than 
  has 
  hitherto 
  

   been 
  supposed. 
  It 
  is 
  chiefly 
  an 
  enemy 
  of 
  the 
  willow, 
  although 
  it 
  also 
  

   attacks 
  alder, 
  birch 
  and 
  poplar. 
  Both 
  adult 
  and 
  larva 
  are 
  injurious 
  ; 
  

   the 
  adult 
  gnaws 
  the 
  tender 
  bark 
  of 
  the 
  young 
  shoots, 
  causing 
  them 
  

   to 
  wilt 
  and 
  die 
  off 
  ; 
  the 
  larva 
  eats 
  into 
  the 
  bark 
  of 
  the 
  stem 
  and 
  main 
  

   branches, 
  almost 
  girdling 
  them, 
  and 
  then 
  bores 
  into 
  the 
  wood 
  itself,
