  Head 
  entirely 
  reddish 
  yellow, 
  only 
  the 
  small 
  ocellar 
  dot 
  being 
  black 
  ; 
  irons 
  opaque 
  

   and 
  with 
  scattered 
  hairs 
  in 
  the 
  middle, 
  shining 
  at 
  vertex 
  and 
  on 
  vertical 
  plates 
  ; 
  

   antennae 
  entirely 
  yellowish, 
  with 
  the 
  third 
  joint 
  three 
  times 
  as 
  long 
  as 
  broad 
  ; 
  palpi 
  

   and 
  proboscis 
  yellowish. 
  All 
  the 
  cephalic 
  bristles 
  are 
  black. 
  The 
  rather 
  opaque 
  

   thorax 
  has 
  in 
  the 
  middle 
  of 
  the 
  dorsum 
  two 
  broad 
  longitudinal 
  stripes 
  of 
  whitish 
  

   dust, 
  which 
  are 
  visible 
  only 
  in 
  certain 
  lights 
  ; 
  on 
  their 
  outer 
  border 
  there 
  is 
  on 
  

   each 
  side 
  a 
  small 
  black 
  stripe, 
  which 
  is 
  sometimes 
  wanting 
  ; 
  the 
  middle 
  brown 
  stripe, 
  

   as 
  described 
  by 
  Karsch, 
  is 
  formed 
  only 
  by 
  the 
  space 
  between 
  the 
  two 
  whitish 
  

   stripes. 
  Very 
  characteristic 
  is 
  the 
  white, 
  black-margined 
  stripe 
  on 
  the 
  notopleural 
  

   line. 
  All 
  the 
  bristles 
  are 
  black, 
  and 
  the 
  short 
  pubescence 
  of 
  the 
  dorsum 
  is 
  likewise 
  

   black. 
  Scutellum 
  like 
  the 
  mesonotum. 
  with 
  short 
  and 
  sparse

   sides.

  soft 
  thin 
  pubescence. 
  Squamulae 
  and 
  halteres 
  

   whitish.

  Abdomen 
  above 
  either 
  entirely 
  shining 
  black, 
  or 
  with 
  the 
  first 
  two 
  

   segments 
  more 
  or 
  less 
  broadly 
  yellowish 
  ; 
  the 
  pubescence 
  is 
  blackish, 
  the 
  bristles 
  

   black. 
  Male 
  genitalia 
  shining 
  black, 
  ovipositor 
  shining 
  black, 
  sometimes 
  reddish 
  

   brown 
  towards 
  the 
  middle. 
  Legs 
  entirely 
  yellow, 
  with 
  black 
  bristles, 
  spines 
  and 
  

   spurs 
  ; 
  front 
  femora 
  with 
  two 
  rows 
  of 
  5-6 
  spines 
  each 
  near 
  the 
  end, 
  middle 
  femora 
  

   with 
  7-8, 
  hind 
  femora 
  with 
  4-5 
  much 
  smaller 
  ones. 
  Wing 
  pattern 
  as 
  figured 
  and 
  

   described 
  by 
  Karsch, 
  the 
  apical 
  hyaline 
  spot 
  being 
  whitish, 
  as 
  stated 
  by 
  Hendel. 
  

   The 
  stigma 
  is 
  entirely 
  black. 
  Sometimes 
  there 
  is 
  a 
  small 
  subhyaline 
  dot 
  in 
  the 
  

   dark 
  base 
  of 
  the 
  first 
  posterior 
  cell, 
  near 
  the 
  fourth 
  vein. 
  The 
  veins 
  are 
  yellowish 
  

   on 
  the 
  hyaline 
  parts, 
  and 
  blackish 
  on 
  the 
  dark 
  parts. 
  

  

  Originally 
  described 
  from 
  Pungo 
  Andongo, 
  and 
  recorded 
  subsequently 
  from 
  

   S. 
  Nigeria, 
  the 
  species 
  seems 
  to 
  be 
  widely 
  distributed 
  in 
  Central 
  Africa, 
  from 
  East 
  

   to 
  West. 
  There 
  are 
  some 
  specimens 
  of 
  both 
  sexes 
  from 
  S. 
  Nigeria, 
  Ibadan, 
  

   29.xi.1913 
  (Dr. 
  W. 
  A. 
  Lamborn); 
  from 
  Nyasaland, 
  Mt. 
  Mlanje, 
  15.iii.13-viii.1913 
  

   (S. 
  A. 
  Neave) 
  ; 
  from 
  Chintechi, 
  Lake 
  Nyasa, 
  ii. 
  1913 
  (J. 
  G. 
  Morgan). 
  

  

  The 
  other 
  species, 
  G. 
  coloniarum, 
  Speiser, 
  has 
  likewise 
  a 
  wide 
  range, 
  extending 
  

   from 
  the 
  East 
  to 
  the 
  West 
  Coast.

  As 
  important 
  additions 
  have 
  to 
  be
