  Tlymenoptera. 
  

  

  convex 
  at 
  the 
  base, 
  flattened 
  towards 
  the 
  apex. 
  Eyes 
  sepa- 
  

   rated 
  on 
  the 
  vertex 
  by 
  a 
  very 
  narrow 
  line; 
  the 
  anterior 
  

   ocellus 
  much 
  larger 
  than 
  the 
  others, 
  which 
  are 
  oval 
  and 
  

   separated 
  by 
  a 
  longitudinal 
  carina. 
  Antennas 
  shorter 
  than 
  

   the 
  mesonotum 
  and 
  scutellum 
  combined, 
  thickened 
  towards 
  

   the 
  apex, 
  the 
  second 
  joint 
  of 
  the 
  flagellum 
  longer 
  than 
  the 
  

   first 
  and 
  third 
  combined, 
  the 
  fifth 
  joint 
  as 
  broad 
  as 
  long. 
  

   Mesonotum 
  finely 
  and 
  rather 
  closely 
  punctured, 
  scutellum

  pleurse 
  

   very 
  finely 
  punctured, 
  the 
  median 
  segment 
  with 
  a 
  concave 
  

   depression 
  rounded 
  posteriorly, 
  a 
  narrow, 
  smooth, 
  triangular 
  

   area 
  on 
  the 
  posterior 
  truncation, 
  the 
  margins 
  of 
  the 
  area 
  

   raised 
  into 
  carinas 
  which 
  converge 
  before 
  the 
  apex 
  of 
  the 
  

   truncation. 
  Abdomen 
  shining, 
  minutely 
  punctured 
  ; 
  the 
  

   first 
  segment 
  concave-truncate 
  at 
  the

  densely 
  clothed 
  

   with 
  long 
  greyish-white 
  pubescence 
  on 
  each 
  side 
  of 
  the 
  trun- 
  

   cation 
  ; 
  the 
  apical 
  half 
  of 
  the 
  second 
  ventral 
  segment 
  very 
  

   stronoly 
  transversely 
  elevated, 
  the 
  basal 
  and 
  apical 
  margins 
  

   of 
  the 
  elevated 
  portion 
  raised 
  and 
  forming 
  strong 
  carinas 
  ; 
  

   sixth 
  segment 
  with 
  a 
  small 
  tubercle 
  on 
  each 
  side 
  near 
  the 
  

   apical 
  angles 
  ; 
  seventh 
  dorsal 
  segment 
  rugosely 
  punctured, 
  

   much 
  lonoer 
  than 
  broad, 
  subcarinate 
  longitudinally 
  in 
  the 
  

   middle, 
  slightly 
  depressed 
  and 
  almost 
  truncate 
  at 
  the 
  apex. 
  

   Radial 
  cell 
  narrowly 
  truncate 
  at 
  the 
  apex,

  cubital 
  cell 
  small, 
  with 
  a 
  

   short 
  petiole, 
  triangular, 
  receiving 
  the 
  second 
  recurrent 
  

   nervure 
  just 
  before 
  the 
  apex; 
  the 
  first 
  recurrent 
  nervure 
  

   received 
  by 
  the 
  first 
  cubital 
  cell, 
  separated 
  from 
  the 
  second 
  

   cubital 
  cell 
  by 
  more 
  than 
  half 
  the 
  length 
  of 
  that 
  cell 
  on 
  the 
  

   cubital 
  nervure 
  ; 
  third 
  transverse 
  cubital 
  nervure 
  not 
  oblique, 
  

   slightly 
  curved 
  outwards, 
  not 
  nearly 
  reaching 
  the 
  apex 
  of 
  the 
  

   radial 
  cell.
