  tiations 
  between 
  the 
  forms 
  so 
  living 
  and 
  those 
  which 
  are 
  parasitic. 
  The 
  most 
  

   important 
  indication 
  of 
  the 
  probable 
  recent 
  development 
  of 
  the 
  phyto- 
  

   phagic 
  habit, 
  however, 
  is 
  found 
  in 
  the 
  assertion 
  by 
  three 
  different 
  authors 
  

   that 
  certain 
  species 
  of 
  Eurytomidae 
  are 
  parasitic 
  in 
  their 
  earlier 
  stages 
  but 
  

   finish 
  their 
  development 
  as 
  plant 
  feeders. 
  Such 
  a 
  mode 
  of 
  development 
  would 
  

   seem 
  to 
  leave 
  little 
  room 
  for 
  doubt 
  that 
  phytophagy 
  as 
  found 
  at 
  present 
  is 
  

   a 
  recent 
  specialization. 
  

  

  Notes 
  and 
  exhibition 
  of 
  specimens 
  

  

  Mr. 
  L. 
  H. 
  Weld 
  told 
  in 
  some 
  detail 
  of 
  the 
  collection 
  of 
  Cynipidae 
  in 
  the 
  

   National 
  Museum, 
  its 
  content 
  and 
  present 
  arrangement. 
  He 
  stated 
  that 
  

   there 
  are 
  probably 
  more 
  Cynipidae 
  in 
  this 
  museum 
  than 
  in 
  any 
  other 
  insti- 
  

   tution. 
  

  

  Mr. 
  S. 
  A. 
  RoHWER 
  discussed 
  the 
  collection 
  for 
  the 
  other 
  groups 
  of 
  the 
  

   Hymenoptera. 
  He 
  announced 
  that 
  the 
  collection 
  of 
  bees 
  had 
  recently 
  been 
  

   completely 
  rearranged, 
  that 
  the 
  Serphoids 
  were 
  now 
  being 
  assembled 
  and 
  

   arranged; 
  that 
  the 
  rearrangement 
  of 
  the 
  sawflies 
  -was 
  completed 
  in 
  1911 
  but* 
  

   that 
  since 
  then 
  much 
  new 
  material 
  had 
  been 
  received 
  ; 
  that 
  the 
  Chalcidoids 
  

   were 
  gradually 
  being 
  put 
  in 
  good 
  order; 
  and 
  that 
  in 
  general 
  the 
  arrangement 
  

   of 
  the 
  collection 
  had 
  been 
  greatly 
  improved 
  in 
  the 
  last 
  few 
  years. 
  He 
  added 
  

   there 
  is 
  still 
  a 
  very 
  great 
  deal 
  to 
  be 
  done 
  but 
  that 
  he 
  believed 
  the 
  National 
  

   Collection 
  of 
  Hymenoptera 
  was 
  probably 
  more 
  extensive 
  than 
  that 
  of 
  any 
  

   other 
  institution 
  in 
  the 
  groups 
  usually 
  considered 
  to 
  be 
  of 
  economic 
  impor- 
  

   tance. 
  He 
  pointed 
  out 
  that 
  the 
  material 
  in 
  the 
  collection 
  was 
  in 
  a 
  large 
  

   measure 
  secured 
  by 
  the 
  cooperation 
  of 
  the 
  economic 
  entomologists 
  of 
  the 
  world 
  

   and 
  that 
  because 
  of 
  this 
  it 
  represented 
  much 
  biological 
  material 
  and 
  notes 
  

   and 
  that 
  in 
  this 
  feature 
  it 
  was 
  probably 
  more 
  complete 
  than 
  any 
  of 
  the 
  large 
  

   collections 
  of 
  other 
  countries. 
  

  

  Mr. 
  E. 
  A. 
  ScHWARZ 
  spoke 
  of 
  four 
  European 
  species 
  of 
  Carabus 
  that 
  had 
  

   been 
  introduced 
  into 
  New 
  England 
  along 
  with 
  the 
  Calosoma 
  beetles. 
  One 
  

   of 
  these, 
  nemoralis, 
  has 
  now 
  spread 
  as 
  far 
  as 
  New 
  Jersey, 
  while 
  auratus 
  has 
  

   bred 
  and 
  spread 
  more 
  sparingly. 
  The 
  other 
  two 
  have 
  apparently 
  failed 
  to 
  

   establish 
  themselves. 
  

  

  Dr. 
  A. 
  G. 
  BoviNG 
  stated 
  that 
  the 
  National 
  Museum 
  collection 
  of 
  Coleop- 
  

   terous 
  larvae 
  is 
  by 
  far 
  the 
  largest 
  in 
  the 
  world.

  For 
  the 
  purpose 
  of 
  encouraging 
  research 
  work 
  on 
  glass 
  the 
  Research 
  Com- 
  

   mittee 
  of 
  the 
  Glass 
  Division 
  of 
  the 
  American 
  Ceramic 
  Society 
  has 
  made 
  

   arrangements 
  for 
  providing 
  glass 
  of 
  desired 
  composition 
  and 
  desired 
  form 
  for 
  

   investigators 
  in 
  this 
  field. 
  The 
  material 
  will 
  be 
  supplied

  be 
  imposed. 
  The 
  recipients 
  

   of 
  the

  given 
  preference 
  

   in 
  reporting 
  the
