  J, 
  luteipes, 
  Lep., 
  

   seriously 
  damages 
  osiers 
  in 
  the 
  Tharandt 
  district. 
  The 
  attack 
  begins 
  

   to 
  be 
  visible 
  in 
  September, 
  and 
  its 
  effects 
  are 
  complete 
  by 
  the 
  end 
  of 
  

   October. 
  Osiers 
  about 
  a 
  yard 
  long 
  and 
  from 
  one-fifth 
  to 
  two-fifths 
  

   of 
  an 
  inch 
  in 
  diameter 
  near 
  the 
  base, 
  wither 
  from 
  12 
  to 
  20 
  inches 
  and 
  

   the 
  bark 
  turns 
  brown 
  or 
  blackish. 
  The 
  tip 
  is 
  held 
  together 
  by 
  the 
  

   bark 
  alone, 
  the 
  tissues 
  beneath 
  being 
  reduced 
  to 
  powder. 
  As 
  the 
  

   injury 
  extends 
  to 
  the 
  thicker 
  portion, 
  it 
  is 
  confined 
  to 
  the 
  medullary 
  

   tube, 
  generally 
  ending 
  in 
  a 
  spiral 
  of 
  one 
  or 
  two 
  turns, 
  indicated 
  by 
  

   a 
  raised 
  mark 
  in 
  the 
  bark. 
  The 
  osier 
  rods 
  often 
  snap 
  or 
  bend 
  at 
  these 
  

   points. 
  The 
  damage 
  resembles 
  that 
  done 
  by 
  the 
  larvae 
  of 
  Oberea 
  

   linearis, 
  L., 
  and 
  also 
  by 
  Coraebus 
  fasciatus, 
  Vill, 
  and 
  Sinoxylon 
  

   jperforans, 
  Schrk. 
  When 
  full 
  grown, 
  the 
  larva 
  returns 
  an 
  inch 
  or 
  so 
  up 
  

   its 
  gallery 
  and 
  hibernates 
  there, 
  pupating 
  in 
  a 
  cocoon 
  in 
  a 
  chamber 
  

   at 
  the 
  side.

  Among 
  the 
  pests 
  of 
  tea 
  included 
  in 
  this 
  report 
  are 
  Xyleborus 
  forni- 
  

   catus,

  The 
  bark-eating 
  borer* 
  has 
  been 
  more 
  prominent 
  than 
  

   usual, 
  living 
  in 
  a 
  short 
  gallery 
  in 
  the 
  stem, 
  which 
  forms 
  a 
  centre 
  of 
  

   decay 
  and 
  permits 
  the 
  access 
  of 
  termites 
  to 
  the 
  tissues 
  ; 
  the 
  cater- 
  

   pillar 
  itself 
  does 
  Httle 
  harm 
  directly, 
  and 
  may 
  be 
  dealt 
  with 
  

   as 
  recommended 
  for 
  red-borer, 
  Zeuzera 
  coffeae 
  [see 
  this 
  Review, 
  

   Ser. 
  A,

  pp. 
  150-151]. 
  Heterusia 
  cingala, 
  Moore, 
  the 
  red 
  

   slug, 
  and 
  nettle-grubs 
  have 
  all 
  been 
  reported 
  on 
  tea 
  [see 
  this 
  

   Review, 
  Ser. 
  A, 
  ii, 
  p. 
  654] 
  and 
  mites, 
  especially 
  Tarsonemus 
  

   translucens, 
  the 
  yellow 
  mite, 
  have 
  been 
  common 
  [see

  pp. 
  151-152 
  and

  Nothing 
  can 
  be 
  done 
  against 
  

   termite 
  injury 
  to 
  tea 
  except 
  to 
  destroy 
  the 
  nests 
  [see

  Other 
  insects 
  reported 
  from

   course 
  of

  are 
  bagworms, 
  Helopeltis

  Capua 
  coffearia 
  was 
  said 
  to 
  be 
  confined 
  to 
  

   acacia-planted 
  fields, 
  while 
  the 
  caterpillars 
  of 
  Taragama

  rubber 
  [see

  included 
  

   the 
  larvae 
  of 
  a 
  Phorid 
  fly 
  which 
  were 
  feeding 
  on 
  the 
  products

  dadap, 
  

   and 
  the 
  Capsid, 
  Helopeltis 
  antonii.

  were 
  both 
  reported 
  on 
  cacao, 
  

   spraying 
  the

  when 
  the
