  The 
  Vine 
  Sphinx, 
  Pergesa 
  elpenor, 
  is 
  especially 
  prone 
  to 
  attack 
  

   vines 
  trained 
  " 
  en 
  espalier." 
  Collection 
  of 
  the 
  eggs 
  and 
  larvae 
  appears 
  

   to 
  be 
  the 
  best 
  means 
  of 
  checking 
  the 
  damage. 
  In 
  1904, 
  in 
  Algeria, 
  

   another 
  Sphinx 
  {Deilephila 
  lineata) 
  did 
  a 
  large 
  amount 
  of 
  damage, 
  but 
  

   the 
  larvae 
  were 
  ultimately 
  got 
  rid 
  of 
  by 
  spraying 
  with 
  arsenite 
  of 
  

   copper. 
  Arctia 
  (Chelonia) 
  caja 
  is 
  occasionally 
  very 
  harmful 
  and 
  

   appears 
  to 
  have 
  a 
  preference 
  for 
  clay 
  soils. 
  

  

  Of 
  the 
  beetle 
  pests, 
  Haltica 
  ampelophaga 
  is 
  very 
  widely 
  distributed 
  

   in 
  Spain, 
  whence, 
  the 
  author 
  thinks, 
  it 
  has 
  invaded 
  the 
  South 
  of 
  France 
  

   and 
  Algeria. 
  In 
  the 
  latter 
  country 
  before 
  the 
  introduction 
  of 
  arsenical 
  

   insecticides 
  it 
  was 
  a 
  veritable 
  plague. 
  The 
  fight 
  against 
  the 
  pest 
  is 
  diffi- 
  

   cult 
  on 
  account 
  of 
  the 
  extremely 
  rapid 
  rate 
  of 
  reproduction. 
  Every 
  

   year 
  in 
  Algeria 
  and 
  in 
  the 
  South 
  of 
  France, 
  the 
  insects 
  are 
  practically 
  

   annihilated, 
  but 
  nevertheless 
  every 
  spring 
  they 
  reappear 
  in 
  large 
  num- 
  

   bers. 
  Its 
  natural 
  enemies 
  are 
  of 
  small 
  consequence 
  and 
  it 
  is 
  very 
  

   difficult 
  to 
  find 
  a 
  practical 
  method 
  of 
  attacking 
  the 
  hibernating 
  insects, 
  

   though 
  something 
  may 
  be 
  done 
  by 
  burning 
  brushwood, 
  shrubs 
  and 
  dry 
  

   leaves. 
  In 
  1887, 
  the 
  Government 
  of 
  Algeria 
  made 
  this 
  destruction 
  

   compulsory 
  within 
  a 
  radius 
  of 
  50 
  yards 
  round 
  the 
  vineyards, 
  but 
  in 
  

   spite 
  of 
  these 
  drastic 
  measures 
  sufficient 
  escaped 
  to 
  assure 
  the 
  repro- 
  

   duction 
  of 
  the 
  pest. 
  The 
  use 
  of 
  the 
  Haltica 
  funnel 
  and 
  of 
  arsenical 
  

   insecticides 
  are 
  the 
  most 
  satisfactory 
  methods 
  of 
  control. 
  

  

  Adoxus 
  obscurus 
  var. 
  vitis 
  at 
  times 
  does 
  serious 
  damage. 
  The 
  perfect 
  

   insect 
  makes 
  its 
  first 
  appearance 
  about 
  the 
  end 
  of 
  May, 
  but 
  the 
  attack 
  

   is 
  especially 
  visible 
  at 
  the 
  end 
  of 
  June 
  and 
  July. 
  The 
  damage 
  done 
  

   to 
  the 
  leaves 
  is 
  not 
  very 
  important, 
  but 
  the 
  grapes 
  are 
  sometimes 
  

   gnawed 
  to 
  such 
  an 
  extent 
  that 
  the 
  whole 
  vintage 
  is 
  destroyed. 
  This 
  

   beetle 
  occasionally 
  abandons 
  entirely 
  an 
  area 
  in 
  which 
  it 
  is 
  swarming 
  

   and 
  it 
  has 
  been 
  suggested 
  that 
  after 
  a 
  certain 
  number 
  of 
  generations 
  

   parthenogenesis 
  occurs 
  and 
  the 
  females 
  migrate 
  en 
  masse 
  to 
  other 
  

   localities. 
  The 
  only 
  practical 
  remedy 
  against 
  the 
  pest 
  is 
  collection 
  

   in 
  funnels 
  as 
  used 
  for 
  Haltica. 
  Details 
  are 
  given 
  of 
  the 
  life-histories 
  

   of 
  three 
  weevils, 
  Rhynchites 
  hetuleti, 
  Otiorrhynchus 
  ligustici 
  and 
  0. 
  sul- 
  

   catus. 
  One 
  hundred 
  species 
  of 
  the 
  genus 
  Otiorrhynchus 
  are 
  known 
  

   in 
  France 
  and 
  of 
  these 
  25 
  attack 
  the 
  vine. 
  The 
  addition 
  of 
  2 
  per 
  cent, 
  

   of 
  bitter 
  aloes 
  to 
  copper 
  sprays 
  against 
  mildew 
  is 
  said 
  to 
  be 
  useful 
  

   against 
  them. 
  

  

  The 
  Longicorn, 
  Vesperus 
  xatarti, 
  is 
  not 
  usually 
  a 
  very 
  serious 
  pest. 
  

   Scraping 
  the 
  bark 
  in 
  February 
  and 
  searching 
  for 
  eggs 
  in 
  all 
  likely 
  

   places 
  is 
  an 
  effective 
  measure, 
  and 
  the 
  injection 
  of 
  bisulphide 
  of 
  carbon 
  

   into 
  the 
  soil 
  is 
  also 
  useful 
  against 
  it 
  [see 
  this 
  Review, 
  Ser. 
  A, 
  i, 
  

   pp. 
  190-191]. 
  

  

  Opatrum 
  sabulosum 
  appears 
  in 
  the 
  beginning 
  of 
  May 
  and 
  attacks 
  

   only 
  French-American 
  grapes, 
  having 
  only 
  become 
  a 
  pest 
  of 
  vines 
  

   since 
  the 
  arrival 
  of 
  Phylloxera. 
  The 
  larvae 
  of 
  Pentodon 
  punctatus 
  also 
  

   attack 
  grafted 
  vines, 
  eating 
  the 
  new 
  tissue 
  around 
  the 
  graft 
  and 
  the 
  

   young 
  buds 
  at 
  their 
  base. 
  The 
  only 
  means 
  of 
  fighting 
  it 
  are 
  the 
  capture 
  

   of 
  the 
  adults 
  at 
  sundown 
  and 
  the 
  injection 
  of 
  bisulphide 
  of 
  carbon 
  

   into 
  the 
  soil 
  to 
  kill 
  the 
  larvae. 
  

  

  Against 
  Lethrus 
  cephalotes 
  the 
  same 
  remedies 
  are 
  applicable 
  as 
  

   against 
  P. 
  punctatus. 
  Anomala 
  vitis 
  is 
  common 
  in 
  the 
  sandy 
  soils 
  

   on 
  the 
  shores 
  of 
  the 
  Mediterranean 
  and 
  has 
  the 
  same 
  habits 
  as 
  Melo- 
  

   lontha. 
  The 
  adults 
  should 
  be 
  collected 
  and 
  the 
  injection 
  of 
  carbon
