  Somewhat 
  resembles 
  furtivus, 
  but 
  the 
  last 
  abscissa 
  of 
  radius 
  is 
  

   much 
  longer, 
  and 
  the 
  sculpture 
  of 
  the 
  abdomen 
  does 
  not 
  agree 
  with 
  

   any 
  specimens 
  of 
  furtivus 
  examined.

  The 
  following 
  notes 
  are 
  based 
  on 
  the 
  type, 
  which 
  is 
  a 
  male 
  speci- 
  

   men: 
  Somewhat 
  resembles 
  rhyssemati 
  in 
  habitus 
  and 
  sculpture 
  of 
  

   the 
  abdomen, 
  but 
  differs 
  in 
  the 
  color 
  of 
  the 
  head, 
  especially 
  the 
  face, 
  

   and 
  in 
  the 
  sculpture 
  of 
  the 
  propodeum. 
  Face 
  smooth 
  and 
  shining 
  

   medially; 
  frons 
  very 
  faintly 
  punctate; 
  antennae 
  broken, 
  20 
  seg- 
  

   ments 
  remaining, 
  the 
  first 
  and 
  second 
  flagellar 
  segments 
  of 
  about 
  

   equal 
  length, 
  twice 
  as 
  long 
  as 
  broad 
  ; 
  malar

  less 
  than 
  half 
  the 
  

   transverse 
  diameter 
  of 
  the 
  opening 
  between 
  clypeus 
  and 
  mandibles; 
  

   thorax 
  rather 
  long 
  and 
  slender, 
  smooth 
  and 
  polished; 
  propodeum 
  

   polished, 
  with 
  a 
  short 
  stub 
  of 
  a 
  median 
  ridge 
  at 
  apex, 
  and 
  from 
  this 
  

   stub 
  toward 
  the 
  base 
  medially 
  impressed, 
  almost 
  grooved, 
  the 
  impres- 
  

   sion 
  traversed 
  by 
  transverse 
  ridges; 
  first 
  abscissa 
  of 
  radius 
  a 
  little 
  

   longer 
  than 
  the 
  recurrent 
  vein
