  Oscinella 
  {Oscinis)frit, 
  L., 
  was 
  found 
  in 
  very 
  large 
  numbers 
  on 
  one 
  

   estate 
  ; 
  on 
  the 
  3rd 
  July 
  a 
  trap 
  crop 
  of 
  barley 
  was 
  sown, 
  and 
  in 
  August 
  

   it 
  was 
  found 
  that 
  90-100 
  per 
  cent, 
  of 
  the 
  plants 
  were 
  infested. 
  Pre- 
  

   ventive 
  measures 
  consisted 
  in 
  reploughing 
  the 
  trap 
  fields 
  and 
  ploughing 
  

   in 
  the 
  germinating 
  fallen 
  grain 
  ; 
  and 
  these 
  proved 
  very 
  effective, 
  

   an 
  infestation 
  of 
  only 
  6 
  per 
  cent, 
  being 
  found 
  in 
  the 
  winter-sown 
  crops. 
  

   About 
  14-15 
  per 
  cent, 
  of 
  the 
  pupae 
  were 
  infected 
  with 
  parasites. 
  On 
  

   another 
  estate 
  30 
  per 
  cent, 
  of 
  the 
  young 
  volunteer 
  wheat 
  was 
  attacked 
  

   and 
  15 
  per 
  cent, 
  of 
  the 
  winter 
  crop.

  The 
  report 
  gives 
  an 
  account 
  of 
  the 
  results 
  of 
  disseminating 
  the 
  

   parasites 
  of 
  the 
  gipsy 
  moth 
  and 
  the 
  brown-tail 
  moth 
  in 
  the 
  infested 
  

   areas 
  during 
  the 
  past 
  year. 
  Owing 
  to 
  the 
  fact 
  that 
  one 
  of 
  the 
  imported 
  

   egg-parasites 
  of 
  the 
  gipsy 
  moth, 
  Anastatus 
  bifasciatus, 
  breeds 
  very 
  

   slowly, 
  extensive 
  collections 
  were 
  made 
  during 
  last 
  winter 
  of 
  para- 
  

   sitised 
  gipsy 
  moth 
  egg-clusters 
  from 
  colonies 
  planted 
  in 
  previous 
  

   years. 
  From 
  this 
  material 
  it 
  was 
  possible 
  to 
  liberate 
  1,500,000 
  para- 
  

   sites 
  ; 
  these 
  were 
  placed 
  in 
  1,500 
  colonies 
  in 
  sections 
  where 
  the 
  insect 
  

   had 
  not 
  become 
  estabhshed. 
  Colonies 
  of 
  Anastatus 
  planted 
  a 
  year 
  

   ago 
  proved 
  to 
  be 
  successful, 
  although 
  the 
  spread 
  was 
  slow. 
  Another 
  

   egg-parasite 
  of 
  the 
  gipsy 
  moth, 
  Schedius 
  kuvanae, 
  has 
  become 
  per- 
  

   fectly 
  estabhshed 
  in 
  several 
  places 
  where 
  it 
  had 
  been 
  planted 
  ; 
  its 
  

   numbers 
  had 
  increased 
  and 
  in 
  some 
  cases 
  it 
  had 
  spread 
  nearly 
  a 
  mile 
  

   and 
  a 
  half 
  beyond 
  the 
  limits 
  of 
  last 
  year's 
  area. 
  The 
  Tachinid 
  Comp- 
  

   silura 
  concinnata 
  was 
  abundant 
  in 
  the 
  summer 
  of 
  1912. 
  Limnerium 
  

   disparidis 
  and 
  Apanteles 
  sp., 
  received 
  from 
  Europe, 
  survived 
  the 
  winter 
  

   and 
  are 
  established 
  ; 
  in 
  the 
  case 
  of 
  the 
  latter 
  species, 
  7 
  per 
  cent, 
  of 
  

   parasitism 
  of 
  gipsy 
  moth 
  larvae 
  was 
  found 
  ; 
  Limnerium 
  has 
  so 
  far 
  

   shown 
  no 
  marked 
  ability 
  to 
  increase. 
  Another 
  species 
  of 
  Apanteles, 
  

   namely 
  A. 
  lacteicolor, 
  an 
  important 
  parasite 
  of 
  the 
  brown- 
  tail 
  moth, 
  

   has 
  been 
  recovered 
  in 
  large 
  numbers 
  and 
  has 
  been 
  found 
  to 
  attack 
  

   gipsy 
  moth 
  caterpillars 
  in 
  widely 
  separated 
  regions. 
  The 
  Calosoma 
  

   beetle 
  (C. 
  sycophanta) 
  has 
  been 
  observed 
  in 
  large 
  numbers 
  where 
  bad 
  

   colonies 
  of 
  the 
  gipsy 
  moth 
  were 
  present 
  ; 
  the 
  good 
  done 
  by 
  the 
  beetle, 
  

   which 
  feeds 
  upon 
  the 
  pupae 
  as 
  well 
  as 
  upon 
  the 
  larvae, 
  is 
  considerable. 
  

   Monodontomerus 
  aereus 
  was 
  found 
  to 
  have 
  spread 
  over 
  practically 
  the 
  

   entire 
  territory 
  known 
  to 
  be 
  infested 
  by 
  the 
  brown-tail 
  moth 
  ;
