  was 
  associated, 
  as 
  was 
  the 
  case 
  last 
  year, 
  with 
  the 
  antlered 
  maple 
  

   caterpillar. 
  The 
  depredations 
  by 
  the 
  snow-white 
  linden 
  moth, 
  

   noticed 
  in 
  our 
  preceding 
  report, 
  were 
  continued 
  in 
  the 
  Catskills 
  and 
  

   extensive 
  injuries 
  in 
  the 
  Adirondacks 
  were 
  also 
  brought 
  to 
  our 
  

   attention. 
  The 
  only 
  hope 
  of 
  preventing 
  damage 
  of 
  this 
  character 
  

   is 
  by 
  the 
  encouragement 
  of 
  natural 
  agents, 
  prominent 
  among 
  

   Vvdiich 
  may 
  be 
  mentioned 
  native 
  birds. 
  The 
  efficiency 
  of 
  in- 
  

   sectivorous 
  birds 
  has 
  been 
  repeatedly 
  emphasized 
  by 
  the 
  Entomolo- 
  

   gist. 
  

  

  The 
  bark 
  borers 
  or 
  Scolytidae 
  comprise 
  a 
  large 
  number 
  of 
  very 
  

   destructive 
  species. 
  The 
  literature 
  relating 
  to 
  this 
  group 
  is 
  greatly 
  

   scattered 
  and 
  comparatively 
  inaccessible, 
  hence 
  a 
  bibliographic 
  

   catalogue 
  is 
  ,a 
  necessary 
  preliminary 
  to 
  further 
  work 
  upon 
  these 
  

   insects. 
  We 
  submit 
  for 
  publication, 
  as 
  an 
  appendix 
  of 
  this 
  report, 
  

   a 
  catalogue 
  of 
  the 
  described 
  Scolytidae 
  of 
  xA.merica 
  north 
  of 
  

   Mexico 
  by 
  Mr 
  J. 
  M. 
  Swaine. 
  

  

  Gall 
  midges. 
  The 
  studies 
  upon 
  this 
  important 
  group 
  have 
  pro- 
  

   gressed 
  very 
  successfully. 
  We 
  have 
  already 
  prepared 
  preliminary 
  

   keys 
  for 
  the 
  separation 
  of 
  most 
  forms 
  into 
  subfamilies, 
  tribes, 
  

   genera 
  and 
  species, 
  together 
  with 
  tables 
  giving 
  the 
  food 
  habits 
  of 
  

   those 
  w^hich 
  have 
  been 
  reared. 
  Some 
  idea 
  of 
  the 
  magnitude 
  of 
  

   this 
  work 
  may 
  be 
  gained 
  when 
  it 
  is 
  remembered 
  that 
  we 
  have 
  

   studied 
  over 
  300 
  bred 
  species 
  and 
  now 
  recognize 
  700 
  species, 
  

   representing 
  about 
  50 
  genera. 
  The 
  systematic 
  arrangement 
  alone 
  

   of 
  this 
  large 
  number 
  of 
  microscopic 
  insects 
  is 
  an 
  immense 
  task. 
  

   And 
  in 
  addition 
  to 
  the 
  above, 
  many 
  descriptions 
  have 
  been 
  drafted 
  

   and 
  numerous 
  biological 
  notes 
  transcribed. 
  

  

  The 
  later 
  work 
  upon 
  these 
  insects 
  has 
  of 
  necessity 
  been 
  con- 
  

   fined 
  mostly 
  to 
  systematic 
  study, 
  owing 
  to 
  the 
  fact 
  that 
  material 
  

   was 
  coming 
  in 
  faster 
  than 
  it 
  could 
  be 
  worked 
  up 
  in 
  a 
  satisfactory 
  

   manner. 
  We 
  have 
  succeeded, 
  in 
  spite 
  of 
  the 
  pressure 
  of 
  other 
  

   matters, 
  in 
  rearing 
  during 
  the 
  past 
  season 
  about 
  75 
  species, 
  the 
  

   biology 
  of 
  most 
  of 
  which 
  was 
  previously 
  unknown. 
  There 
  is 
  on 
  

   hand 
  a 
  large 
  series 
  of 
  galls 
  from 
  which 
  some 
  extremely 
  desirable 
  

   material 
  may 
  be 
  expected 
  another 
  season. 
  The 
  work 
  upon 
  this 
  

   group 
  is 
  so 
  well 
  in 
  hand 
  that 
  there 
  should 
  be 
  no 
  difficulty 
  in 
  bring- 
  

   ing 
  it 
  to 
  a 
  successful 
  conclusion 
  in 
  the 
  near 
  future. 
  

  

  The 
  rearing 
  and 
  care 
  of 
  breeding 
  jars 
  containing 
  gall 
  midges 
  

   require 
  much 
  time.
