  In 
  beginning 
  the 
  study 
  of 
  the 
  mouth-parts 
  of 
  any 
  group 
  of 
  

   insects, 
  one 
  naturally 
  commences 
  with 
  the 
  lowest 
  or 
  most 
  general- 
  

   ized 
  members, 
  expecting 
  of 
  course 
  to 
  find 
  the 
  mouth-parts 
  of 
  

   these 
  older 
  forms 
  to 
  present 
  the 
  most 
  generalized 
  condition 
  to 
  

   be 
  found 
  in 
  the 
  order. 
  Hence, 
  in 
  beginning 
  a 
  study 
  of 
  the 
  com- 
  

   parative 
  anatomy 
  of 
  the 
  adult 
  Hymenopterous 
  mouth 
  several 
  

   years 
  ago 
  in 
  the 
  entomological 
  laboratory 
  of 
  Stanford 
  University,

  Prof. 
  Vernon

  Kellogg, 
  the 
  writer 
  began 
  

   on 
  those 
  of 
  Teuthredinidae. 
  A 
  few 
  generalizations 
  on 
  the 
  draw- 
  

   mgs 
  made 
  in 
  connection 
  with 
  the 
  study 
  may 
  prove 
  interesting 
  to 
  

   the 
  members 
  of 
  this 
  Society. 
  

  

  Following 
  Cresson's 
  list 
  all 
  the 
  sub-families 
  were' 
  studied 
  with 
  

   the 
  exception 
  of 
  Hylotominae. 
  The 
  parts 
  present 
  difficulty 
  in

   section

  the 
  reason 
  that 
  they 
  are 
  intimately 
  joined 
  or 
  connected 
  

   by 
  a 
  verv 
  efficient 
  membrane 
  or 
  tissue. 
  The
