  INTRODUCTION. 
  

  

  Begun 
  in 
  an 
  effort 
  to 
  get 
  additional 
  light 
  on 
  certain 
  problems 
  not 
  

   solved 
  by 
  then-existing 
  literature, 
  this 
  study 
  has 
  gradually 
  grown 
  to 
  

   the 
  proportions 
  indicated 
  by 
  the 
  title. 
  That 
  we 
  have 
  been 
  able 
  to 
  

   go 
  so 
  far 
  is 
  due 
  in 
  large 
  part 
  to 
  generous 
  loans 
  of 
  material 
  for 
  which 
  

   we 
  record 
  our 
  great 
  appreciation. 
  The 
  initial 
  basis 
  of 
  the 
  work 
  was 
  

   the 
  very 
  good 
  collection 
  of 
  Ploiariinae 
  in 
  the 
  United 
  States 
  Na- 
  

   tional 
  Museum, 
  but 
  we 
  have 
  been 
  favored 
  with 
  loans 
  of 
  large 
  num- 
  

   bers 
  of 
  specimens 
  by 
  the 
  Academy 
  of 
  Natural 
  Sciences 
  of 
  Phila- 
  

   delphia,
