  The 
  transverse 
  median 
  nervure 
  is 
  received 
  distinctly 
  in 
  

   front 
  of 
  the 
  basal 
  ; 
  the 
  first 
  recurrent 
  nervure 
  is 
  received 
  

   shortly 
  behind 
  the 
  middle 
  of 
  the 
  cellule 
  ; 
  the 
  areolet 
  may 
  

   be 
  absent. 
  

  

  Comes 
  near 
  Metopius 
  and 
  Bassus 
  in 
  some 
  respects 
  — 
  in 
  

   the 
  thickened 
  legs 
  for 
  instance 
  — 
  but 
  differs 
  from 
  them 
  in 
  the 
  

   abdomen 
  not 
  being 
  so 
  broad 
  at 
  the 
  base. 
  Its 
  characteristics 
  

   are 
  the 
  thickened 
  legs, 
  the 
  mesothorax 
  dilated 
  in 
  the 
  

   middle, 
  the 
  large 
  fiat 
  scutellum, 
  and 
  the 
  distinctly 
  petio- 
  

   lated 
  areolet. 
  

  

  The 
  genus 
  contains 
  two 
  sections. 
  One 
  represented 
  by 
  

   6". 
  trilineata, 
  having 
  a 
  distinct 
  appendiculated 
  areolet, 
  and 
  

   a 
  keel 
  outside 
  the 
  metapleural 
  spiracles 
  ; 
  the 
  other 
  repre- 
  

   sented 
  by 
  vS. 
  crasszpes, 
  having 
  no 
  areolet 
  and 
  a 
  keel 
  on 
  

   the 
  outer 
  and 
  inner 
  side 
  of 
  the 
  spiracles. 
  Unfortunately 
  

   I 
  have 
  no 
  females, 
  both 
  the 
  species 
  being 
  represented 
  by 
  

   males.
