  Cameron, 
  Hymenoptera 
  Orientalia. 
  

  

  the 
  antennae 
  are 
  more 
  slender 
  and 
  longer 
  ; 
  the 
  fore 
  tarsi 
  

   longer 
  compared 
  with 
  the 
  tibiae, 
  with 
  the 
  base 
  of 
  the 
  tarsi 
  

   more 
  sharply 
  incised 
  ; 
  the 
  head 
  is 
  more 
  sharply 
  oblique 
  

   behind 
  the 
  eyes 
  ; 
  the 
  clypeus 
  roundly 
  convex, 
  with 
  the 
  

   apex 
  oblique 
  ; 
  the 
  labrum 
  shorter 
  than 
  the 
  clypeus, 
  its 
  

   apex 
  bluntly 
  rounded, 
  and 
  the 
  fore 
  tibiae 
  are 
  distinctly 
  

   narrowed 
  at 
  the 
  base. 
  

  

  This 
  genus 
  also 
  comes 
  near 
  to 
  Ceratocryptus 
  described 
  

   in 
  this 
  paper, 
  it 
  having 
  the 
  same 
  form 
  of 
  thorax 
  and 
  

   abdomen, 
  but 
  differs 
  in 
  the 
  much 
  larger 
  areolet, 
  in 
  the 
  

   smooth 
  median 
  segment, 
  which 
  has 
  the 
  spiracles 
  less 
  

   elongated, 
  in 
  the 
  shorter 
  petiole, 
  which 
  has 
  not 
  the 
  post- 
  

   petiole 
  so 
  distinctly 
  narrowed 
  from 
  the 
  rest 
  of 
  it 
  ; 
  the 
  

   antennae 
  are 
  more 
  slender, 
  with 
  the 
  third 
  joint 
  longer 
  

   compared 
  with 
  the 
  fourth 
  ; 
  the 
  metathorax 
  is 
  shorter 
  and 
  

   more 
  rounded 
  at 
  the 
  apex. 
  The 
  transverse 
  median 
  

   nervure 
  is 
  interstitial. 
  The 
  species 
  have 
  a 
  considerable 
  

   resemblance 
  to 
  Heterocryphts, 
  which 
  may 
  be 
  distinguished 
  

   by 
  the 
  smaller, 
  round 
  metathoracic 
  spiracles.
