  Head 
  entirely 
  yellow 
  and 
  opaque 
  ; 
  occiput 
  with 
  a 
  narrow 
  black 
  stripe 
  on 
  each 
  

   side, 
  extending 
  from 
  the 
  neck 
  to 
  the 
  lower 
  third 
  of 
  the 
  eyes 
  ; 
  frons 
  narrower 
  than 
  

   the 
  eye 
  and 
  longer 
  than 
  broad, 
  unicolorous, 
  with 
  a 
  very 
  small 
  black 
  ocellar 
  dot. 
  

   The 
  face 
  and 
  unspotted 
  jowls 
  are 
  yellowish, 
  while 
  the 
  occipital 
  lower 
  swellings 
  

   are 
  more 
  lightly 
  coloured 
  and 
  surrounded 
  above 
  with 
  the 
  black 
  stripe 
  ; 
  upper 
  

   mouth-border 
  prominent. 
  Antennae 
  entirely 
  pale 
  yellowish, 
  only 
  a 
  little 
  shorter 
  

   than 
  the 
  face, 
  with 
  the 
  third 
  joint 
  rather 
  broad, 
  and 
  with 
  a 
  shortly 
  pubescent 
  

   arista. 
  Palpi 
  and 
  proboscis 
  pale 
  yellowish. 
  All 
  the 
  cephalic 
  bristles 
  are 
  pale 
  

   yellowish, 
  only 
  the 
  short 
  outer 
  vt. 
  f 
  the 
  acute 
  and 
  numerous 
  ocp. 
  and 
  the 
  i. 
  or. 
  being 
  

   black 
  ; 
  there 
  are 
  no 
  distinct 
  ocellar 
  bristles 
  ; 
  there 
  are 
  only 
  two 
  pairs 
  of 
  longer 
  i. 
  or. 
  y 
  

   but 
  on 
  the 
  same 
  line 
  are 
  some 
  black, 
  much 
  shorter, 
  bristly 
  hairs. 
  The 
  lower 
  occipital 
  

   hairs 
  are 
  whitish 
  ; 
  the 
  bristly 
  hairs 
  near 
  the 
  borders 
  of 
  the 
  mouth 
  are 
  yellowish. 
  

   Thorax 
  entirely 
  yellowish, 
  less 
  shining, 
  with 
  pale 
  short 
  golden-yellowish 
  pubescence 
  ; 
  

   on 
  each 
  side 
  there 
  are 
  two 
  black 
  longitudinal 
  stripes, 
  one 
  extending 
  from 
  the 
  

   shoulders 
  along 
  the 
  notopleural 
  line 
  to 
  the 
  root 
  of 
  the 
  wing, 
  and 
  continuous 
  with 
  

   the 
  black 
  postalar 
  calli 
  and 
  the 
  very 
  glistening 
  black 
  mesophragma 
  ; 
  the 
  other 
  

   is 
  parallel 
  with 
  the 
  former 
  but 
  ends 
  at 
  the 
  suture, 
  being 
  continued 
  beyond 
  it 
  only 
  

   by 
  a 
  short 
  ill-defined 
  darkish 
  stripe 
  ; 
  the 
  occipital 
  black 
  stripe 
  is 
  continuous 
  with 
  

   the 
  notopleural 
  one. 
  The 
  pleurae 
  and 
  the 
  breast 
  are 
  entirely 
  whitish 
  yellow, 
  

   unspotted, 
  the 
  contrast 
  between 
  the 
  black 
  and 
  the 
  whitish 
  parts 
  being 
  very 
  striking, 
  

   when 
  the 
  thorax 
  is 
  viewed 
  from 
  the 
  side. 
  Hypopleural 
  spot 
  whitish. 
  Scutellum 
  

   of 
  a 
  light 
  yellowish 
  colour, 
  like 
  the 
  posterior 
  part 
  of 
  the 
  back 
  of 
  the 
  mesonotum, 
  

   but 
  a 
  little 
  more 
  shining. 
  Postscutellum 
  shining 
  black. 
  All 
  the 
  macrochaetae 
  

   are 
  yellowish, 
  those 
  of 
  the 
  pleurae 
  being 
  lighter 
  ; 
  one 
  mpl. 
  ; 
  pt. 
  much 
  weaker 
  

   than 
  the 
  st. 
  ; 
  even 
  the 
  scjp. 
  are 
  black. 
  Squamulae 
  blackish, 
  with 
  a 
  long 
  dark 
  fringe 
  ; 
  

   halteres 
  pale 
  yellowish. 
  Abdomen 
  shining 
  yellow 
  on 
  the 
  basal 
  half, 
  blackened 
  

   on 
  the 
  apical 
  half, 
  the 
  last 
  three 
  segments 
  having 
  black 
  lateral 
  borders 
  ; 
  venter 
  

   whitish 
  ; 
  hairs 
  and 
  bristles 
  yellowish. 
  Ovipositor 
  flattened, 
  broadly 
  obtuse 
  at 
  

   the 
  end, 
  shining 
  reddish 
  with 
  pale 
  pubescence. 
  Legs 
  entirely 
  whitish 
  yellow, 
  those 
  

   of 
  the 
  front 
  pair 
  wanting 
  in 
  the 
  type 
  ; 
  apical 
  spur 
  of 
  the 
  middle 
  tibiae 
  black 
  ; 
  

   hairs 
  of 
  the 
  posterior 
  row 
  of 
  the 
  hind 
  tibiae 
  brownish. 
  The 
  wings 
  are 
  almost 
  

   wholly 
  and 
  evenly 
  infuscated 
  ; 
  the 
  lower 
  border 
  of 
  the 
  fuscous 
  part 
  ends 
  about 
  

   on 
  a 
  line 
  extending 
  from 
  the 
  point 
  of 
  the 
  anal 
  cell 
  to 
  the 
  lower 
  anterior 
  corner 
  of 
  

   the 
  discoidal 
  and 
  the 
  upper 
  third 
  of 
  the 
  second 
  posterior 
  cell 
  ; 
  but 
  this 
  line 
  is 
  wavy, 
  

   having 
  some 
  rounded 
  projections, 
  three 
  of 
  which 
  are 
  in 
  the 
  second 
  and 
  three 
  in 
  the 
  

   third 
  posterior 
  cell. 
  There 
  is 
  besides 
  a 
  very 
  small 
  sub 
  hyaline 
  rounded 
  dot 
  in 
  the 
  

   basal 
  part 
  of 
  the 
  first 
  posterior 
  cell, 
  a 
  little 
  before 
  the 
  hind 
  cross-vein 
  and 
  closer 
  

   to 
  the 
  fourth 
  than 
  to' 
  the 
  third 
  longitudinal 
  vein. 
  The 
  stigma 
  is 
  as 
  long 
  as 
  the 
  

   second 
  costal 
  cell 
  and 
  is 
  black, 
  with 
  a 
  narrow 
  short 
  subhyaline 
  streak 
  near 
  the 
  

   base 
  at 
  costa, 
  being 
  as 
  broad 
  as 
  a 
  third 
  only 
  of 
  the 
  stigma 
  itself. 
  The 
  hyaline 
  streak 
  

   at 
  fore 
  border 
  beyond 
  the 
  stigma 
  is 
  shorter 
  than 
  the 
  stigma 
  itself, 
  and 
  does 
  not 
  

   extend 
  below 
  beyond 
  the 
  middle 
  of 
  the 
  marginal 
  cell. 
  The 
  small 
  alula 
  is 
  entirely 
  

   brown, 
  while 
  the 
  axillary 
  lobe 
  is 
  entirely 
  hyaline. 
  The 
  third 
  longitudinal 
  vein 
  

   has 
  2-3 
  bristles 
  beyond 
  the 
  small 
  cross-vein. 
  The 
  last 
  portions 
  of 
  the 
  third 
  and 
  

   fourth 
  longitudinal 
  veins 
  are 
  quite 
  straight 
  and 
  parallel, 
  or 
  only 
  a 
  little 
  divergent.
