   on 
  each 
  side,

  apical 
  one 
  occupying 
  the 
  

   whole 
  space 
  between 
  the 
  two 
  apical 
  bristles, 
  and 
  the

  and 
  white 
  dust 
  ; 
  first 
  segment 
  shining 
  black 
  

   on 
  the 
  basal 
  half, 
  white-dusted 
  on 
  the 
  apical 
  half, 
  thus 
  forming 
  a 
  complete 
  and 
  

   broad

  ;

  third 
  and 
  fourth 
  

   entirely

  with 
  a 
  narrow 
  blackish 
  basal 
  band. 
  The 
  abdominal 
  hairs 
  are 
  white 
  

   on 
  the 
  white, 
  black 
  on 
  the 
  dark 
  parts 
  ; 
  all 
  the 
  bristles 
  are 
  black. 
  Venter

   brown. 
  Ovipositor 
  entirely 
  reddish, 
  darker 
  at 
  base, 
  with 
  short 
  black

  dark 
  

   brownish 
  hairs. 
  Legs 
  with 
  dark 
  reddish 
  coxae 
  and 
  with 
  blackish 
  femora, 
  which 
  

   are 
  dark 
  reddish 
  at

  ;

  and 
  tarsi 
  pale 
  yellowish, 
  but 
  the 
  latter 
  darkened 
  

   at 
  end 
  ; 
  bristles 
  black 
  ; 
  hairs 
  dark 
  on 
  femora 
  and 
  whitish 
  on 
  tibiae. 
  Wings 
  whitish 
  

   hyaline, 
  with 
  black 
  veins, 
  but 
  the 
  costa 
  and 
  the 
  first 
  longitudinal 
  are 
  whitish 
  on 
  

   the 
  hyaline 
  parts, 
  like 
  the 
  fourth 
  and 
  fifth 
  veins. 
  At 
  the 
  extreme 
  base 
  there 
  is 
  

   a 
  short 
  fuscous 
  band, 
  extending 
  from 
  the 
  humeral 
  cross-vein 
  to 
  the 
  base 
  of 
  the 
  

   second 
  basal 
  cell 
  ; 
  after 
  this 
  band 
  there 
  are 
  the 
  blackish 
  streaks, 
  which 
  are 
  broad 
  

   and 
  placed 
  one 
  in 
  each 
  cell, 
  except 
  the 
  anal 
  cell, 
  and 
  are 
  present 
  even 
  in 
  the 
  base 
  

   of 
  the 
  submarginal 
  cell 
  and 
  in 
  the 
  upper 
  corner 
  of 
  the 
  base 
  of 
  the 
  discoidal 
  cell. 
  

   The 
  second 
  costal 
  cell 
  is 
  infuscated 
  at 
  the 
  two 
  ends 
  ; 
  the 
  stigma 
  is 
  hyaline, 
  with 
  

   a 
  blackish 
  base. 
  The 
  bands 
  are 
  deep 
  fuscous, 
  the 
  darker 
  spots 
  of 
  the 
  marginal 
  band 
  

   along 
  the 
  costa 
  being 
  thus 
  less 
  distinct. 
  Basal 
  band 
  oblique, 
  beginning 
  at 
  fore 
  

   border 
  beyond 
  the 
  stigma, 
  passing 
  across 
  the 
  small 
  cross- 
  vein 
  and 
  ending 
  narrowly 
  

   at 
  the 
  tip 
  of 
  the 
  sixth 
  vein 
  ; 
  it 
  is 
  almost 
  straight 
  on 
  its 
  outer 
  border, 
  with 
  fuscous 
  

   teeth 
  on 
  the 
  inner 
  edge, 
  two 
  of 
  which 
  extend 
  into 
  the 
  third 
  posterior 
  cell 
  ; 
  at 
  base 
  

   of 
  the 
  discoidal 
  cell 
  it 
  is 
  united 
  with 
  the 
  fuscous 
  basal 
  streak 
  of 
  the 
  same 
  cell. 
  The 
  

   marginal 
  band 
  extends 
  below 
  to 
  the 
  third 
  vein, 
  passing 
  even 
  below 
  it 
  near 
  the 
  apex 
  

   and 
  ending 
  at 
  wing 
  border 
  near 
  the 
  middle 
  of 
  the 
  first 
  posterior 
  cell. 
  The 
  oblique 
  

   middle 
  band 
  is 
  rather 
  broad 
  ; 
  it 
  begins 
  at 
  middle 
  of 
  the 
  last 
  portion 
  of 
  the 
  third 
  

   vein 
  and 
  ends 
  at 
  wing 
  border 
  just 
  below 
  the 
  end 
  of 
  the 
  fourth 
  vein 
  ; 
  the 
  hyaline 
  

   indentation 
  between 
  the 
  marginal 
  and 
  the 
  middle 
  band 
  is 
  narrower 
  than 
  the 
  terminal 
  

   part 
  of 
  the 
  marginal 
  band 
  itself. 
  Cubital 
  band 
  less 
  oblique, 
  beginning 
  at 
  hind 
  wing 
  

   border, 
  passing 
  across 
  the 
  hind 
  cross- 
  vein 
  and 
  ending 
  rather 
  narrowly 
  above 
  it 
  in 
  

   the 
  first 
  posterior 
  cell, 
  quite 
  separated 
  from 
  the 
  basal 
  band 
  ; 
  its 
  external 
  border 
  

   is 
  convex, 
  while 
  the 
  internal 
  one 
  is 
  concave, 
  the 
  band 
  being 
  thus 
  distinctly 
  arcuate. 
  

   Axillary 
  lobe 
  entirely 
  hyaline, 
  like 
  the 
  alula.
