  The 
  Hymenoptera 
  belonging 
  to 
  the 
  superfamilies 
  Vespoidea 
  and 
  

   Sphecoidea 
  obtamed 
  by 
  the 
  Yale 
  Peruvian 
  Expedition 
  were 
  col- 
  

   lected 
  in 
  the 
  following 
  localities: 
  Panama 
  Canal 
  Zone, 
  Panama; 
  

   San 
  Miguel, 
  Peru; 
  Santa 
  Ana, 
  Peru; 
  OUantaytambo, 
  Peru; 
  Arequipa, 
  

   Peru; 
  Desert 
  of 
  Salavery, 
  Peru; 
  Cuzco, 
  Peru. 
  The 
  following 
  five 
  

   southeastern 
  Peruvian 
  localities, 
  Paltaybamba, 
  Tortontoy, 
  Huadquina, 
  

   Tincochaca, 
  and 
  Pampaconas 
  River 
  can 
  only 
  be 
  found 
  in 
  some 
  of 
  

   the 
  most 
  recent 
  atlases, 
  but 
  the 
  Pampaconas 
  River 
  is 
  a 
  stream 
  lying 
  

   between 
  the 
  Urubamba 
  and 
  Apurimac 
  Rivers. 
  

  

  Of 
  this 
  lot 
  of 
  Hymenoptera 
  referred 
  to, 
  consisting 
  of 
  26 
  species, 
  14 
  

   are 
  described 
  as 
  new, 
  11 
  are 
  determined 
  as 
  heretofore 
  described 
  

   species, 
  and 
  1 
  which 
  belongs 
  to 
  the 
  genus 
  Pepsis 
  has 
  not 
  been 
  deter- 
  

   mined. 
  Nearly 
  all 
  of 
  those 
  species 
  which 
  were 
  determined 
  as 
  having 
  

   been 
  heretofore 
  described 
  belong 
  to 
  the 
  family 
  Vespidae, 
  and 
  most 
  of 
  

   these 
  have 
  a 
  wide 
  distribution 
  throughout 
  the 
  entire 
  Neotropical 
  

   region. 
  The 
  insects 
  belonging 
  to 
  the 
  family 
  Eumenidae 
  are 
  all 
  

   related 
  to 
  insects 
  found 
  m 
  the 
  high 
  mountains 
  of 
  the 
  Andes, 
  and 
  

   more 
  especially 
  with 
  the 
  insects 
  belonging 
  to 
  the 
  Chilean 
  fauna. 
  

   Insects 
  of 
  the 
  superfamily 
  Sphecoidea 
  show 
  no 
  special 
  affinities 
  with 
  

   any 
  region, 
  in 
  fact 
  this 
  may 
  be 
  said 
  for 
  many 
  of 
  them 
  although 
  a 
  few 
  

   of 
  the 
  species 
  have 
  their 
  allies 
  either 
  in 
  insects 
  belonging 
  to 
  the 
  

   Chilean 
  fauna 
  or 
  insects 
  which 
  belong 
  to 
  the 
  high 
  mountain 
  fauna 
  of 
  

   Guatemala, 
  etc. 
  But 
  few 
  Hymenoptera 
  have 
  ever 
  been 
  described 
  

   from 
  Peru 
  and 
  it 
  is 
  not 
  surprising 
  that 
  more 
  than 
  half 
  of 
  those 
  sub- 
  

   mitted 
  should 
  turn 
  out 
  to 
  be 
  new 
  species. 
  

  

  In 
  the 
  case 
  of 
  the 
  two 
  species 
  of 
  Mutillids 
  described 
  it 
  may 
  be 
  

   possible 
  that 
  they 
  have 
  been 
  described 
  by 
  some 
  of 
  the 
  older 
  authors, 
  

   but 
  no 
  description 
  could 
  be 
  found 
  to 
  apply 
  well 
  enough 
  to 
  make 
  their 
  

   determination 
  certain. 
  The 
  two 
  Mutillids 
  are 
  referred 
  to 
  the 
  genus 
  

   SphsRrophthalma 
  Blake 
  where 
  they 
  run 
  in 
  Andre's 
  synopsis 
  of
