  Cameron, 
  Hymenoptera 
  Orientalia. 
  

  

  This 
  genus 
  has 
  the 
  neuration 
  of 
  Siobla 
  or 
  Selandria, 
  

   except 
  that 
  in 
  the 
  latter 
  the 
  basal 
  nervure 
  is 
  united 
  to 
  

   the 
  cubital. 
  It 
  differs 
  markedly 
  from 
  both 
  in 
  the 
  long, 
  

   slender 
  antennae, 
  in 
  the 
  incised 
  apex 
  of 
  the 
  clypeus, 
  in 
  the 
  

   frontal 
  area 
  being 
  sharply 
  and 
  clearly 
  bounded 
  by 
  distinct 
  

   keels, 
  and 
  in 
  it 
  being 
  united 
  to 
  the 
  eyes 
  by 
  a 
  keel. 
  The 
  

   wings 
  are 
  rather 
  longer 
  than 
  usual, 
  the 
  costa 
  is 
  not 
  so 
  

   much 
  dilated 
  before 
  the 
  stigma 
  as 
  in 
  Selandria, 
  the 
  sutures 
  

   on 
  the 
  vertex 
  are 
  distinct, 
  narrow, 
  but 
  deep 
  ; 
  the 
  head 
  

   moderately 
  developed 
  behind 
  the 
  eyes, 
  but 
  not 
  quite 
  so 
  

   much 
  so 
  as 
  in 
  Siobla. 
  It 
  is 
  further 
  a 
  much 
  more 
  slen- 
  

   derly 
  built 
  insect 
  than 
  Siobla 
  or 
  Selandria, 
  more 
  like 
  

   Stromocerus.

  Nigra; 
  scapo 
  antennarum, 
  linea 
  pronoti,

  Long, 
  fere 
  6 
  mm. 
  

  

  Antennae 
  filiform, 
  longer 
  than 
  the 
  abdomen, 
  black 
  ; 
  the 
  

   basal 
  joint 
  white; 
  the 
  flagellum 
  covered 
  with 
  short, 
  stiff, 
  

   black 
  pubescence 
  ; 
  the 
  third 
  and 
  fourth 
  equal 
  in 
  length. 
  

   Head 
  black, 
  the 
  clypeus, 
  labrum, 
  the 
  base 
  of 
  the 
  mandibles 
  

   broadly, 
  and 
  the 
  palpi, 
  white 
  ; 
  shining, 
  impunctate 
  ; 
  the 
  

   frontal 
  area 
  with 
  some 
  obscure 
  striae. 
  Thorax 
  shining, 
  

   impunctate 
  ; 
  the 
  hinder 
  part 
  of 
  the 
  pronotum 
  broadly, 
  

   the 
  tegulae, 
  a 
  large 
  oblique 
  mark 
  on 
  the 
  hinder 
  part 
  of 
  the 
  

   mesopleurae 
  — 
  broad 
  at 
  the 
  base, 
  gradually 
  narrowed 
  

   towards 
  the 
  apex 
  — 
  clear 
  white. 
  Wings 
  large, 
  hyaline, 
  

   the 
  nervures 
  black, 
  the 
  lower 
  part 
  of 
  the 
  stigma 
  fuscous. 
  

   The 
  second- 
  cubital 
  cellule 
  is 
  distinctly 
  longer 
  than 
  the 
  

   *(/ 
  thir€l; 
  and 
  receives 
  the 
  recurrent 
  nervure 
  near 
  to 
  the 
  apex; 
  * 
  

   the 
  second 
  shortly 
  before 
  the 
  middle 
  of 
  the 
  cellule 
  ; 
  the 
  

   basal 
  nervure 
  shortly 
  before 
  the 
  middle 
  ; 
  the 
  radial 
  

   nervure 
  curved 
  above, 
  its 
  lower 
  part 
  almost 
  perpendicular.
