  Legs 
  entirely 
  and 
  evenly 
  reddish 
  from 
  the 
  coxae 
  to 
  the 
  end 
  of 
  the 
  tarsi 
  ; 
  their 
  

   short 
  pubescence 
  is 
  pale, 
  but 
  it 
  is 
  black 
  on 
  the 
  outer 
  side 
  of 
  the 
  femora 
  ; 
  front 
  

   femora 
  with 
  long 
  black 
  hairs 
  above, 
  and 
  with 
  3-5 
  black 
  bristles 
  below 
  at 
  the 
  end 
  ; 
  

   middle 
  tibiae 
  with 
  two 
  apical 
  black 
  spurs, 
  and 
  with 
  a 
  short 
  row 
  of 
  2-4 
  short 
  and 
  

   stout 
  black 
  bristles 
  at 
  the 
  base 
  on 
  the 
  hind 
  sides 
  ; 
  hind 
  tibiae 
  with 
  a 
  complete 
  row. 
  

  

  Wings 
  (fig. 
  1, 
  B) 
  long 
  and 
  broad, 
  with 
  a 
  well 
  developed 
  costal 
  bristle; 
  the 
  stigma 
  

   is 
  of 
  usual 
  length 
  ; 
  the 
  second 
  longitudinal 
  vein 
  is 
  straight 
  ; 
  the 
  third 
  is 
  bristly 
  

   throughout, 
  moderately 
  bent 
  backwards 
  beyond 
  the 
  middle 
  of 
  its 
  last 
  portion, 
  and 
  

   parallel 
  with 
  the 
  last 
  portion 
  of 
  the 
  fourth 
  ; 
  small 
  cross-vein 
  below 
  the 
  end 
  of 
  the 
  

   first 
  longitudinal 
  vein 
  and 
  beyond 
  the 
  middle 
  of 
  the 
  discoidal 
  cell 
  ; 
  hind 
  cross- 
  vein 
  

   long, 
  as 
  long 
  as 
  or 
  even 
  a 
  little 
  longer 
  than 
  its 
  distance 
  from 
  the 
  small 
  one, 
  reaching 
  

   below 
  the 
  fifth 
  vein 
  at 
  an 
  obtuse 
  angle 
  ; 
  point 
  of 
  the 
  anal 
  cell 
  acute 
  and 
  longer 
  than 
  

   the 
  second 
  basal 
  cell. 
  The 
  base 
  of 
  the 
  wing 
  is 
  hyaline 
  to 
  a 
  little 
  before 
  the 
  end 
  of 
  

   the 
  second 
  basal 
  cell 
  and 
  to 
  the 
  base 
  of 
  the 
  stigma 
  ; 
  but 
  in 
  fully 
  coloured 
  specimens 
  

   the 
  second 
  costal 
  cell, 
  the 
  basal 
  half 
  of 
  the 
  first 
  basal 
  cell, 
  the 
  base 
  of 
  the 
  second 
  

   basal 
  and 
  more 
  narrowly 
  that 
  of 
  the 
  anal 
  cell, 
  are 
  pale 
  yellowish. 
  The 
  stigma 
  is 
  

   entirely 
  dark 
  brown, 
  without 
  any 
  hyaline 
  part. 
  The 
  brown 
  patch 
  extending 
  across 
  

   the 
  greater 
  part 
  of 
  the 
  wing 
  is 
  darker 
  on 
  the 
  upper 
  half, 
  fighter 
  on 
  the 
  lower, 
  and 
  

   distinctly 
  yellowish 
  in 
  some 
  parts 
  towards 
  the 
  middle. 
  At 
  the 
  fore 
  border 
  there 
  is 
  

   a 
  single 
  hyaline 
  indentation 
  of 
  triangular 
  shape 
  just 
  beyond 
  the 
  stigma, 
  reaching 
  

   with 
  its 
  point 
  the 
  third 
  longitudinal 
  vein, 
  a 
  little 
  beyond 
  the 
  small 
  cross-vein. 
  The 
  

   three 
  rounded 
  hyaline 
  spots 
  in 
  the 
  middle 
  are 
  as 
  follows 
  : 
  one 
  at 
  the 
  end 
  of 
  the 
  first 
  

   basal 
  cell, 
  before 
  the 
  small 
  cross-vein 
  ; 
  one 
  a 
  little 
  before 
  the 
  middle 
  of 
  the 
  first 
  

   posterior 
  cell, 
  above 
  the 
  upper 
  end 
  of 
  the 
  hind 
  cross-vein 
  ; 
  and 
  one 
  of 
  greater 
  size 
  

   before 
  the 
  end 
  of 
  the 
  discoidal 
  cell, 
  in 
  contact 
  above 
  with 
  the 
  fourth 
  vein, 
  and 
  

   distant 
  beneath 
  from 
  the 
  fifth 
  vein. 
  At 
  the 
  hind 
  border 
  there 
  are 
  two 
  hyaline 
  

   indentations 
  ; 
  a 
  smaller 
  one 
  of 
  more 
  triangular 
  shape 
  in 
  the 
  second 
  posterior 
  cell, 
  

   pointing 
  with 
  its 
  inner 
  corner 
  to 
  the 
  upper 
  basal 
  angle 
  of 
  the 
  same 
  cell, 
  without 
  

   reaching 
  it 
  ; 
  a 
  larger 
  and 
  broader 
  one 
  towards 
  the 
  middle 
  of 
  the 
  third 
  posterior 
  cell, 
  

   with 
  its 
  inner, 
  broad 
  end 
  in 
  contact 
  with 
  the 
  fifth 
  vein, 
  but 
  without 
  entering 
  the 
  

   discoidal 
  cell. 
  The 
  axillary 
  lobe 
  is 
  mainly 
  hyaline, 
  with 
  a 
  brown 
  spot 
  at 
  the 
  end 
  of 
  

   the 
  anal 
  cell, 
  not 
  extending 
  beyond 
  the 
  axillary 
  vein 
  ; 
  the 
  alula 
  is 
  hyaline. 
  The 
  

   narrow 
  extreme 
  base 
  of 
  the 
  marginal 
  cell 
  is 
  hyaline, 
  like 
  a 
  small 
  elongate 
  spot 
  into 
  

   the 
  first 
  basal 
  cell, 
  just 
  before 
  and 
  above 
  the 
  end 
  of 
  the 
  second 
  basal 
  cell; 
  the 
  

   whitish 
  oblique 
  stripe 
  into 
  the 
  brown 
  base 
  of 
  the 
  third 
  posterior 
  cell 
  is 
  very 
  striking. 
  

   The 
  indentation 
  of 
  the 
  fore 
  border 
  and 
  the 
  three 
  hyaline 
  spots 
  in 
  the 
  middle 
  are 
  

   distinctly 
  whitish, 
  like 
  the 
  inner 
  or 
  superior 
  part 
  of 
  the 
  broad 
  indentation 
  of 
  the 
  

   third 
  posterior 
  cell.

  in

  trunks

  the 
  specimens 
  of 
  this 
  couple 
  are 
  not 
  fully

   as 
  is 
  frequently 
  the 
  case 
  with 
  bred 
  flies.
