  The 
  shot-hole 
  borer 
  does 
  not 
  frequent 
  GreviUea 
  or 
  Alhizzia 
  stifulata, 
  

   though 
  it 
  may 
  attack 
  sickly 
  branches. 
  There 
  are 
  several 
  records 
  of 
  

   X. 
  fornicatus 
  occurring 
  in 
  Alhizzia 
  moluccana, 
  but 
  opinions 
  differ 
  as 
  

   to 
  the 
  condition 
  of 
  the 
  plants 
  attacked. 
  In 
  some 
  cases 
  the 
  insects 
  

   occurred 
  in 
  large 
  numbers 
  in 
  twigs 
  and 
  branches 
  already 
  killed 
  by 
  a 
  

   fungus, 
  and 
  the 
  presence 
  of 
  several 
  species 
  indicated 
  that 
  they 
  were 
  

   not 
  the 
  primary 
  cause 
  of 
  injury 
  ; 
  but 
  in 
  another 
  case 
  the 
  infested 
  

   branches 
  showed 
  no 
  original 
  fungus 
  disease. 
  Yearling 
  plants 
  of 
  

   Crotalaria 
  striata 
  are 
  reported 
  as 
  being 
  attacked 
  in 
  one 
  instance, 
  and 
  

   deserted 
  tunnels 
  were 
  once 
  found 
  in 
  loquat, 
  and 
  in 
  castor 
  oil 
  plants 
  

   all 
  stages 
  of 
  the 
  borer 
  were 
  present. 
  Green 
  found 
  what 
  was 
  

   apparently 
  this 
  species 
  tunnelhng 
  only 
  in 
  dead 
  wood 
  in 
  Para 
  rubber, 
  

   and 
  also 
  reports 
  a 
  single 
  case 
  of 
  specimens 
  alleged 
  to 
  have 
  been 
  taken 
  

   from 
  guava, 
  and 
  twigs 
  of 
  Bixa 
  orellana 
  were 
  apparently 
  attacked 
  

   by 
  this 
  borer, 
  which 
  also 
  attacks 
  isolated 
  cacao 
  trees 
  growing 
  amongst 
  

   tea. 
  The 
  quantity 
  of 
  gum 
  present 
  in 
  the 
  bark 
  of 
  healthy 
  cacao 
  trees 
  

   protects 
  them, 
  but 
  should 
  the 
  vitality 
  of 
  the 
  tree 
  be 
  lowered 
  by 
  canker 
  

   or 
  other 
  disease, 
  it 
  may 
  be 
  attacked 
  ; 
  such 
  trees, 
  in 
  a 
  favourable 
  

   condition 
  for 
  the 
  breeding 
  of 
  these 
  beetles, 
  are 
  therefore 
  a 
  great 
  menace 
  

   to 
  tea 
  plantations 
  ; 
  when 
  cultivating 
  cacao, 
  all 
  dying 
  branches 
  should 
  

   be 
  removed 
  and 
  the 
  cut 
  surface 
  tarred. 
  The 
  author 
  found 
  several 
  

   specimens 
  of 
  a 
  large 
  black 
  thrips 
  in 
  galleries 
  of 
  X. 
  fornicatus, 
  in 
  this 
  

   tree, 
  but 
  they 
  did 
  not 
  appear 
  to 
  be 
  predaceous.

  The 
  author 
  in 
  May 
  1913 
  found 
  numbers 
  of 
  mites, 
  Eriophyes 
  ribis, 
  

   on 
  black-currant 
  plants, 
  the 
  buds 
  of 
  which 
  had 
  not 
  unfolded. 
  He 
  

   recommends 
  the 
  following 
  method 
  of 
  discovering 
  and 
  examining 
  

   these 
  mites 
  : 
  attacked 
  buds 
  are 
  placed 
  in 
  a 
  dry 
  glass 
  tube 
  and 
  the 
  

   mites 
  will 
  soon 
  leave 
  them 
  and 
  settle 
  on 
  the 
  walls 
  of 
  the 
  glass 
  ; 
  they 
  

   can 
  then 
  be 
  preserved 
  by 
  filling 
  the 
  glass 
  with 
  60^ 
  alcohol. 
  Buds 
  

   attacked 
  by 
  these 
  mites 
  wither 
  and 
  drop 
  off 
  about 
  the 
  middle 
  of 
  June 
  ; 
  

   the 
  mites 
  emerge 
  from 
  the 
  buds, 
  oviposit 
  in 
  new 
  ones 
  and 
  then 
  die 
  ; 
  

   a 
  new 
  generation 
  appearing 
  the 
  following 
  year. 
  The 
  mites 
  are 
  spread 
  

   from 
  place 
  to 
  place 
  through 
  the 
  agency 
  of 
  winds, 
  birds 
  or 
  insects, 
  

   also 
  through 
  young 
  shoots 
  of 
  currants 
  used 
  as 
  cuttings.
