  Body 
  robust, 
  of 
  comparatively 
  large 
  size,

  the 
  frons, 
  concave 
  in 
  the

  ; 
  3rd 
  joint 
  about 
  as 
  long

  the 
  first 
  two 
  joints 
  together, 
  of 
  a 
  rectangular 
  

  

  shape, 
  with 
  the 
  upper 
  terminal 
  angle 
  acute 
  but 
  not 
  very 
  prominent 
  ; 
  arista 
  longer 
  

  

  than 
  the

  long 
  pubescence. 
  Mouth-opening 
  broadened 
  

  

  .anteriorly 
  ; 
  palpi

  the 
  

  

  subfamily 
  ; 
  proboscis 
  short, 
  with 
  short 
  and 
  broad 
  terminal 
  flaps. 
  Occipital 
  row 
  

  

  formed 
  by 
  stout 
  obtuse 
  whitish 
  bristles 
  ; 
  inner 
  vt. 
  very 
  long 
  ; 
  oc. 
  long 
  and 
  strong, 
  

  

  widely 
  distant 
  from 
  each 
  other 
  at 
  the 
  base 
  ; 
  two 
  s. 
  or., 
  not 
  in 
  the 
  same 
  line 
  with 
  

  

  the 
  three 
  i. 
  or., 
  but 
  converging 
  in 
  front 
  and 
  thus 
  the 
  anterior 
  pair 
  about 
  in 
  front 
  

  

  of 
  the 
  oc. 
  ; 
  middle 
  frontal 
  band 
  bare 
  ;

  stout 
  hairs. 
  Thorax 
  about 
  as 
  long 
  as 
  broad, 
  moderately 
  

  

  convex 
  above, 
  with 
  sparse 
  scattered 
  pubescence, 
  even 
  on 
  the 
  pleurae. 
  Chaetotaxy 
  

  

  complete, 
  but 
  with 
  no 
  distinct 
  scp. 
  ; 
  dc. 
  placed 
  near 
  the 
  suture 
  and 
  a 
  little 
  before 
  

  

  the 
  line 
  of 
  the 
  a. 
  sa. 
  ; 
  one 
  mpl. 
  ; 
  pt. 
  a 
  little 
  weaker 
  than 
  the 
  st. 
  Scutellum 
  broadly 
  

  

  triangular, 
  gently 
  convex 
  above, 
  clothed 
  with 
  sparse 
  hairs 
  ; 
  b. 
  set. 
  long 
  and 
  diverging 
  ; 
  

  

  <i. 
  set. 
  well 
  developed, 
  but 
  broken 
  in 
  the 
  type. 
  Abdomen 
  elongate, 
  narrower 
  

  

  than 
  the 
  thorax, 
  nearly 
  bare 
  above 
  and 
  on 
  the 
  sides, 
  with 
  some 
  rather 
  stout 
  bristles 
  

  

  -at 
  the 
  end 
  ; 
  male 
  genitalia 
  globose 
  and 
  rather 
  prominent 
  downwards. 
  Legs 
  rather 
  

  

  slender, 
  the 
  femora 
  not 
  incrassated 
  ; 
  front 
  femora 
  with 
  a 
  complete 
  row 
  of 
  strong 
  

  

  bristles 
  below 
  ; 
  middle 
  tibiae 
  with 
  a 
  single 
  spur 
  ; 
  hind 
  tibiae 
  with 
  no 
  distinct 
  row 
  

  

  on 
  the 
  outer 
  side. 
  Wings 
  rounded 
  and 
  very 
  broad 
  ; 
  costal 
  bristle 
  well 
  developed, 
  

  

  with 
  a 
  second 
  much 
  smaller 
  one 
  before 
  it 
  ; 
  there 
  is 
  also 
  a 
  group 
  of 
  4-5 
  short 
  

  

  bristly 
  hairs 
  at 
  the 
  costa 
  near 
  the 
  humeral 
  cross- 
  vein 
  and 
  its 
  incision. 
  The 
  incision 
  

  

  at 
  the 
  end 
  of 
  the 
  auxiliary 
  vein 
  is 
  present, 
  but 
  much 
  shorter 
  and 
  less 
  prominent 
  

  

  than 
  typically. 
  Auxiliary 
  vein 
  well 
  developed, 
  but 
  ending 
  at 
  a 
  straight 
  angle 
  

  

  and 
  there 
  evanescent 
  ; 
  first 
  vein 
  ending 
  about 
  at 
  middle 
  of 
  the 
  fore 
  border 
  and 
  

  

  distant 
  from 
  the 
  costa 
  (the 
  costal 
  and 
  subcostal 
  cells 
  being 
  thus 
  very 
  broad), 
  and 
  

  

  suddenly 
  bent 
  forwards 
  at 
  tip 
  ; 
  it 
  is 
  clothed 
  with 
  bristles, 
  which 
  on 
  its 
  terminal 
  

  

  part 
  are 
  very 
  long. 
  Stigma 
  distinct, 
  about 
  as 
  broad 
  as 
  long. 
  Second 
  vein 
  long, 
  

  

  straight, 
  a 
  little 
  bent 
  forwards 
  at 
  the 
  apex, 
  ending 
  nearer 
  to 
  the 
  end 
  of 
  the 
  3rd 
  

  

  than 
  to 
  that 
  of 
  the 
  first 
  vein. 
  Third 
  vein 
  quite 
  straight, 
  clothed 
  with 
  short 
  bristles 
  

  

  to 
  the 
  middle 
  of 
  its 
  last 
  portion 
  ; 
  the 
  submarginal 
  cell 
  is 
  greatly 
  widened 
  at 
  the 
  

  

  end, 
  because 
  the 
  2nd 
  vein 
  is 
  strongly 
  divergent 
  from 
  the 
  3rd, 
  which 
  is 
  parallel 
  with 
  

  

  the 
  longitudinal 
  axis 
  of 
  the 
  wing. 
  Fourth 
  vein 
  likewise 
  straight 
  and 
  in 
  its 
  last 
  

  

  portion 
  quite 
  parallel 
  with 
  the 
  last 
  portion 
  of 
  the 
  third. 
  Small 
  cross- 
  vein 
  normally 
  

  

  developed, 
  straight, 
  perpendicular, 
  about 
  as 
  long 
  as 
  its 
  distance 
  from 
  the 
  upper 
  

  

  end 
  of 
  the 
  hind 
  cross- 
  vein 
  ; 
  it 
  is 
  placed 
  near 
  the 
  terminal 
  third 
  of 
  the 
  upper 
  border
