  from 
  the 
  face 
  by 
  a 
  suture. 
  Eyes 
  

   large, 
  reaching 
  near 
  to 
  the 
  base 
  of 
  the 
  mandibles 
  ; 
  the 
  

   upper 
  orbits 
  margined. 
  Mesonotum 
  trilobate, 
  reticu- 
  

   lated 
  in 
  the 
  middle 
  at 
  the 
  apex. 
  Metathorax 
  elongate, 
  

   with 
  a 
  gradually 
  rounded 
  slope 
  to 
  the 
  apex 
  ; 
  the 
  spiracles 
  

   placed 
  near 
  the 
  middle, 
  oval. 
  Legs 
  elongate, 
  slender, 
  

   the 
  hinder 
  tarsi 
  large, 
  elongate, 
  smooth, 
  or 
  striated 
  on 
  

   the 
  outer 
  side 
  ; 
  the 
  hinder 
  tarsi 
  nearly 
  equal 
  in 
  length 
  

   to 
  the 
  tibiae 
  ; 
  the 
  claws 
  with 
  a 
  stout 
  basal 
  tooth, 
  shorter 
  

   than 
  the 
  other, 
  which 
  is 
  curved 
  and 
  thinner; 
  coxae 
  large, 
  

   elongate. 
  Abdominal 
  segments 
  smooth 
  ; 
  the 
  petiole 
  

   longer 
  than 
  the 
  second 
  segment, 
  gradually 
  widened 
  towards 
  

   the 
  apex; 
  the 
  other 
  segments 
  not 
  much 
  broader 
  than 
  

   their 
  length, 
  smooth 
  ; 
  the 
  gastrocceli 
  distinct; 
  the 
  ovipositor 
  

   long, 
  issuing 
  from 
  a 
  ventral 
  cleft. 
  The 
  spiracles 
  are 
  small, 
  

   oval, 
  almost 
  round, 
  and 
  are 
  placed 
  near 
  the 
  middle 
  of 
  the 
  

   segment. 
  

  

  This 
  genus 
  is 
  nearly 
  allied 
  to 
  RJiyssa 
  and 
  Epirhyssa, 
  

   which 
  differ 
  from 
  it 
  in 
  the 
  transversely 
  striated 
  mesonotum, 
  

   in 
  the 
  shorter 
  metathorax, 
  in 
  the 
  mandibles 
  being 
  biden- 
  

   tate, 
  in 
  the 
  shorter 
  petiole, 
  which 
  has 
  the 
  spiracles 
  placed 
  

   much 
  nearer 
  the 
  base, 
  and 
  in 
  the 
  longer 
  hinder 
  tarsi, 
  which 
  

   are 
  distinctly 
  longer 
  than 
  the 
  tibiae.
