  Eyes 
  distinctly 
  incised 
  on 
  the

  narrowed 
  behind 
  them. 
  Occiput 
  margined. 
  Antennae 
  

   with 
  over 
  50 
  joints. 
  Wings 
  with 
  three 
  cubital 
  cellules 
  ; 
  

   the 
  probrachial 
  nervure 
  received 
  shortly 
  behind 
  the 
  

   middle 
  of 
  the 
  cellule 
  ; 
  the 
  anal 
  nervure 
  interstitial. 
  

   Stigma 
  large 
  ; 
  the 
  second 
  cubital 
  cellule 
  longer 
  than 
  

   broad. 
  Parapsidal 
  furrows 
  distinct. 
  Median 
  segment 
  

   keeled 
  down 
  the

  Abdomen 
  subsessile; 
  keeled 
  

   down 
  the 
  middle 
  at

  the 
  basal 
  three 
  segments 
  

   opaque, 
  alutaceous, 
  longer 
  than 
  the 
  apical 
  four, 
  and 
  

   becoming 
  gradually 
  shorter 
  ; 
  the 
  apical 
  segments 
  are 
  

   smooth

  The

  reach 
  near 
  to 
  the 
  base 
  

   of

  ; 
  the 
  occiput

  there 
  is 
  a

   depression

  abdominal 
  segments 
  

   behind 
  the 
  stigmas, 
  and 
  they 
  are 
  sharply 
  margined 
  at 
  the 
  

   sides 
  ; 
  the 
  third

   apices 
  laterally 
  ; 
  the

  cubital 
  nervure
