  undertaken 
  work 
  of 
  destruction 
  by 
  means 
  of 
  parasites. 
  Thousands 
  

   of 
  these 
  beneficial 
  parasites 
  have 
  been 
  brought 
  into 
  this 
  country, 
  

   taken 
  to 
  the 
  laboratory 
  at 
  Saugus, 
  reared 
  to 
  maturity, 
  the 
  dangerous 
  

   hyperparasites 
  destroyed 
  and 
  the 
  beneficial 
  forms 
  liberated 
  under 
  

   conditions 
  favorable 
  to 
  their 
  multiplication. 
  Our 
  investigations 
  

   showed 
  that 
  certain 
  of 
  these 
  European 
  enemies 
  had 
  survived 
  the 
  

   winter 
  and 
  that 
  there 
  is 
  at 
  least 
  a 
  fair 
  prospect 
  of 
  considerable 
  

   benefit 
  resulting 
  from 
  this 
  systematic 
  importation 
  of 
  natural 
  enemies. 
  

   The 
  general 
  situation 
  is 
  distinctly 
  more 
  encouraging 
  than 
  was 
  the 
  

   case 
  last 
  year. 
  A 
  general 
  campaign 
  of 
  repression 
  has 
  been 
  con- 
  

   ducted 
  most 
  vigorously 
  and 
  the 
  beneficial 
  result 
  therefrom 
  is 
  easily 
  

   seen 
  in 
  Boston 
  and 
  vicinity. 
  Furthermore, 
  the 
  Federal 
  Department 
  

   of 
  Agriculture 
  is 
  cooperating 
  with 
  the 
  Massachusetts 
  authorities 
  in 
  

   an 
  effort 
  to 
  prevent 
  the 
  further 
  spread 
  of 
  the 
  gipsy 
  moth 
  in 
  partic- 
  

   ular. 
  This 
  latter 
  phase 
  of 
  the 
  work 
  consists 
  largely 
  in 
  keeping 
  all 
  

   highways 
  free 
  from 
  caterpillars, 
  so 
  as 
  to 
  make 
  it 
  impossible 
  for 
  

   automobiles 
  to 
  carry 
  these 
  leaf 
  feeders 
  into 
  uninfested 
  regions. 
  The 
  

   gipsy 
  moth 
  is 
  being 
  combated 
  strenuously 
  in 
  Rhode 
  Island 
  and 
  

   Connecticut 
  and 
  there 
  is 
  a 
  very 
  strong 
  probability 
  that 
  the 
  few 
  

   insects 
  in 
  the 
  last 
  named 
  state 
  will 
  be 
  speedily 
  exterminated. 
  

  

  Forest 
  insects. 
  There 
  were 
  two 
  outbreaks 
  the 
  past 
  season 
  of 
  

   exceptional 
  interest. 
  The 
  striped 
  maple 
  worm, 
  Anisota 
  rubi- 
  

   cund 
  a 
  Fabr. 
  was 
  very 
  abundant 
  on 
  sugar 
  maples 
  in 
  Berlin 
  and 
  

   Stephentown, 
  Rensselaer 
  co., 
  stripping 
  the 
  leaves 
  from 
  large 
  blocks 
  

   of 
  forest 
  and 
  proving 
  injurious 
  over 
  hundreds 
  of 
  acres. 
  The 
  

   snow-white 
  linden 
  moth, 
  Ennomos 
  subsignarius 
  Hiibn. 
  

   was 
  extraordinarily 
  abundant 
  on 
  beech 
  trees 
  in 
  the 
  Catskills, 
  de- 
  

   foliating 
  large 
  areas 
  in 
  and 
  about 
  the 
  township 
  of 
  Hardenburgh. 
  

   Both 
  of 
  these 
  outbreaks 
  are 
  unusual, 
  as 
  neither 
  of 
  these 
  species 
  has 
  

   been 
  injurious 
  in 
  New 
  York 
  State 
  for 
  some 
  years. 
  Detailed 
  

   accounts 
  of 
  these 
  insects 
  have 
  been 
  prepared 
  and 
  will 
  be 
  published 
  

   in 
  the 
  Entomologist's 
  report. 
  

  

  Aquatic 
  insects. 
  The 
  studies 
  of 
  our 
  fresh-water 
  insects 
  have 
  

   been 
  continued. 
  Dr 
  James 
  G. 
  Needham 
  has 
  completed 
  his 
  report 
  

   on 
  the 
  work 
  done 
  at 
  Old 
  Forge, 
  N. 
  Y. 
  in 
  1905, 
  and 
  it 
  will 
  be 
  pub- 
  

   lished 
  as 
  an 
  appendix 
  to 
  the 
  Entomologist's 
  report.

  the 
  Stone 
  flies 
  (Plecoptera) 
  begun 
  by 
  Dr 
  Needham 
  several 
  

   years 
  ago, 
  is 
  nearly 
  completed 
  and 
  will 
  prove 
  an 
  addition 
  to 
  our 
  

   knowledge 
  of 
  this 
  group.

   ing 
  the 
  Caddis 
  flies 
  (Trichoptera) 
  for 
  the 
  past 
  six 
  years, 
  has 
  nearly 
  

   completed 
  his 
  report 
  upon 
  these 
  forms.
