  22. 
  CRYPTANURA 
  EXCALIBUR, 
  new 
  species 
  

  

  This 
  and 
  the 
  next 
  following 
  two 
  species 
  and 
  probably 
  Mesostenus 
  

   platyurus 
  Brulle 
  form 
  a 
  group 
  distinct 
  from 
  the 
  rest 
  of 
  the 
  genus 
  in 
  

   the 
  long, 
  stout 
  ovipositor 
  which 
  in 
  side 
  view 
  is 
  almost 
  clavate, 
  becoming 
  

   gradually 
  much 
  deeper 
  toward 
  the 
  apex. 
  Brulle's 
  species 
  is 
  not 
  known 
  

   to 
  me, 
  but 
  it 
  may 
  be 
  distinguished 
  from 
  the 
  present 
  species 
  by 
  its 
  red 
  

   propodeum. 
  

  

  Female.
