  Collection 
  of 
  Hymenoptera 
  made 
  by 
  Escalera 
  in 
  S.W. 
  Persia 
  

   is 
  of 
  much 
  interest, 
  since 
  it 
  adds 
  considerably 
  to 
  our 
  know- 
  

   ledge 
  of 
  the 
  distribution 
  of 
  the 
  genus. 
  

  

  The 
  measurements 
  of 
  length, 
  as 
  on 
  previous 
  occasions, 
  

   have 
  been 
  taken 
  from 
  the 
  front 
  of 
  the 
  head 
  to 
  the 
  apical 
  

   margin 
  of 
  the 
  second 
  abdominal 
  segment, 
  unless 
  special 
  

   mention 
  is 
  made 
  to 
  the 
  contrary. 
  All 
  the 
  types 
  are 
  in 
  the 
  

   National 
  Collection.

  A 
  comparison 
  between 
  the 
  types 
  of 
  these 
  two 
  species 
  

   proves 
  them 
  to 
  be 
  identical. 
  The 
  locality 
  of 
  capture 
  for 
  

   both 
  is 
  Biskra. 
  B. 
  korbi 
  has 
  priority 
  of 
  publication 
  by 
  a 
  

   few 
  months, 
  although 
  the 
  descriptions 
  of 
  both 
  were 
  published 
  

   in 
  the 
  same 
  year.
