  Haplothrips 
  aculeatus, 
  F., 
  Aeoloihrips 
  fasciatus, 
  L., 
  and 
  Limothrips 
  

   denticornis, 
  Hal., 
  found 
  in 
  1912 
  on 
  tobacco 
  leaves 
  in 
  the 
  government 
  of 
  

   Tchernigov 
  by 
  Miss 
  A. 
  Bragin. 
  The 
  author 
  is 
  of 
  opinion 
  that 
  both 
  

   species 
  were 
  swept 
  by 
  the 
  wind 
  on 
  to 
  the 
  tobacco 
  and 
  perished 
  on 
  the 
  

   sticky 
  surface 
  of 
  the 
  latter 
  ; 
  he 
  does 
  not 
  consider 
  it 
  in 
  any 
  way 
  probable 
  

   that 
  they 
  feed 
  on 
  tobacco. 
  Scololhrips 
  sexmacidatus, 
  Pergande, 
  found 
  

   by 
  F. 
  Zaitzev 
  near 
  Tifiis 
  in 
  1912. 
  This 
  is 
  the 
  first 
  time 
  that 
  this 
  

   species 
  has 
  been 
  reported 
  in 
  Russia, 
  as 
  up 
  till 
  now 
  it 
  has 
  been 
  known 
  

   only 
  from 
  the 
  United 
  States, 
  according 
  to 
  Moulton 
  and 
  Qualey 
  ; 
  it 
  

   is 
  probable 
  that 
  it 
  has 
  been 
  imported 
  into 
  Russia 
  from 
  the 
  cotton 
  

   plantations 
  of 
  North 
  America. 
  Physothrips 
  atratiis, 
  Hal., 
  and 
  Frank- 
  

   liniella 
  tenuicornis, 
  Uz., 
  found 
  on 
  tobacco 
  in 
  the 
  government 
  of 
  

   Tchernigov 
  in 
  1912 
  by 
  Miss

  Drepanothrips 
  viticola, 
  Mokrz., 
  

   found 
  by 
  Mokrzecki 
  in 
  1901 
  near 
  Novorossiisk, 
  is 
  injurious 
  to 
  vines, 
  

   causing 
  red 
  spots 
  to 
  appear 
  on 
  them. 
  The 
  females 
  winter 
  underneath 
  

   the 
  bark 
  and 
  appear 
  on 
  the 
  leaves 
  in 
  April.

  This 
  Adoretus 
  has 
  been 
  known 
  for 
  some 
  time 
  past 
  in 
  Samoa 
  as 
  the 
  

   Rose 
  Beetle, 
  from 
  its 
  principal 
  food-plant. 
  Until 
  recently 
  it 
  has 
  not 
  

   been 
  regarded 
  as 
  a 
  pest, 
  but 
  now 
  it 
  has 
  taken 
  to 
  feeding 
  on 
  cacao, 
  and 
  

   its 
  depredations 
  may 
  probably 
  become 
  serious. 
  The 
  author 
  believes 
  

   it 
  to 
  be 
  also 
  the 
  cause 
  of 
  damage 
  observed 
  on 
  Liberian 
  coffee 
  ; 
  species 
  of 
  

   the 
  same 
  genus 
  are 
  recognised 
  pests 
  of 
  coffee 
  and 
  cacao 
  in 
  Java. 
  The 
  

   beetle 
  hides 
  during 
  the 
  day, 
  and 
  feeds 
  at 
  night, 
  being 
  attracted 
  by 
  

   light. 
  It 
  occurs 
  all 
  the 
  year 
  round. 
  Little 
  is 
  known 
  of 
  its 
  life-history, 
  

   but 
  it 
  is 
  surmised 
  that 
  breeding 
  takes 
  place 
  at 
  all 
  times 
  of 
  the 
  year, 
  

   since 
  larvae 
  are 
  always 
  to 
  be 
  found 
  among 
  the 
  roots 
  of 
  grasses 
  or 
  

   other 
  plants 
  ; 
  these 
  larvae 
  are 
  not 
  known 
  to 
  do 
  any 
  damage. 
  It 
  

   seems 
  that 
  the 
  cacao 
  trees 
  most 
  liable 
  to 
  be 
  attacked 
  are 
  those 
  which 
  

   are 
  unprotected 
  by 
  larger 
  trees, 
  and 
  which 
  stand 
  more 
  or 
  less 
  alone. 
  

   Combating 
  the 
  beetle 
  is 
  a 
  matter 
  of 
  some 
  difficulty, 
  mechanical 
  and 
  

   chemical 
  methods 
  which 
  have 
  been 
  tried 
  having 
  proved 
  of 
  little 
  use 
  ; 
  

   in 
  the 
  case 
  of 
  spraying 
  (nature 
  of 
  spray 
  not 
  stated), 
  the 
  beetle 
  was 
  

   destroyed, 
  but 
  the 
  leaves 
  of 
  the 
  plant 
  were 
  badly 
  damaged. 
  No 
  

   natural 
  enemies 
  which 
  would 
  keep 
  the 
  beetle 
  quite 
  under 
  control 
  are 
  

   known 
  in 
  the 
  vicinity 
  where 
  the 
  damage 
  is 
  done, 
  but 
  the 
  author 
  

   suggests 
  that, 
  were 
  they 
  introduced, 
  the 
  enemies 
  which 
  he 
  lias 
  advo- 
  

   cated 
  for 
  use 
  against 
  the 
  rhinoceros 
  beetle

  rhinoceros,
