  Abdomen 
  shining 
  black, 
  with 
  black 
  pubescence 
  and 
  short 
  black 
  bristles 
  ; 
  venter 
  

  

  black, 
  but 
  less 
  shining 
  ; 
  ovipositor 
  glistening 
  black 
  and 
  with 
  black 
  pubescence. 
  

  

  Legs 
  black, 
  with 
  yellow 
  tibiae 
  and 
  tarsi 
  ; 
  the 
  femora 
  are 
  narrowly 
  yellowish 
  at 
  

  

  tip, 
  and 
  the 
  hind 
  tibiae 
  are 
  infuscated 
  at 
  base 
  ; 
  front 
  femora 
  with 
  four 
  long 
  bristles 
  

  

  beneath. 
  Wings 
  with 
  long 
  and 
  strong, 
  but 
  simple 
  costal 
  bristle 
  ; 
  the 
  veins 
  are 
  

  

  black, 
  but 
  they 
  are 
  yellowish 
  at 
  base 
  and 
  on 
  the 
  hyaline 
  indentations. 
  Small 
  

  

  -cross-vein 
  placed 
  on 
  the 
  apical 
  third 
  of 
  the 
  discoidal 
  cell, 
  which 
  is 
  much 
  broadened 
  

  

  outwardly 
  ; 
  hind 
  cross- 
  vein 
  convex 
  outwardly 
  ; 
  last 
  portions 
  of 
  the 
  third 
  and 
  fourth 
  

  

  veins 
  about 
  parallel, 
  the 
  former 
  being 
  only 
  a 
  little 
  curved 
  downwards 
  near 
  the 
  end 
  ; 
  

  

  lower 
  angle 
  of 
  the 
  anal 
  cell 
  acute, 
  but 
  not 
  produced. 
  The 
  base 
  of 
  the 
  wing 
  is 
  

  

  quite 
  hyaline, 
  the 
  dividing 
  line 
  being 
  straight 
  and 
  running 
  obliquely 
  from 
  the 
  

  

  distal 
  end 
  of 
  the 
  second 
  costal, 
  second 
  basal 
  and 
  anal 
  cells 
  to 
  the 
  hind 
  border 
  ; 
  the 
  

  

  stigma 
  is 
  entirely 
  black. 
  At 
  the 
  fore 
  border 
  there 
  are 
  two 
  triangular, 
  hyaline 
  

  

  indentations 
  of 
  equal 
  size, 
  just 
  beyond 
  the 
  stigma 
  and 
  reaching 
  with 
  their 
  obtuse 
  

  

  point 
  the 
  third 
  longitudinal 
  vein. 
  The 
  wholly 
  black 
  discoidal 
  cell 
  has 
  near 
  its 
  base 
  

  

  a 
  rounded 
  hyaline 
  spot, 
  which 
  is 
  above 
  in 
  contact 
  with 
  the 
  fourth 
  vein, 
  while 
  

  

  below 
  it 
  is 
  distant 
  from 
  the 
  fifth. 
  At 
  the 
  hind 
  border 
  there 
  are 
  four 
  hyaline 
  identa- 
  

  

  tions, 
  disposed 
  in 
  pairs 
  ; 
  two 
  shorter 
  and 
  broader 
  into 
  the 
  third 
  posterior 
  cell, 
  

  

  reaching 
  the 
  fifth 
  vein, 
  the 
  basal 
  being 
  twice 
  as 
  broad 
  as 
  the 
  apical 
  one 
  ; 
  the 
  other 
  

  

  two 
  into 
  the 
  second 
  posterior 
  cell, 
  the 
  basal 
  one 
  extending 
  along 
  the 
  hind 
  cross-vein 
  

  

  (but 
  without 
  being 
  in 
  contact 
  with 
  it) 
  to 
  the 
  fourth 
  longitudinal 
  vein 
  ; 
  the 
  apical 
  

  

  one 
  is 
  curved 
  inwardly 
  and 
  ends 
  broadly 
  obtuse 
  at 
  the 
  third 
  vein, 
  crossing 
  the 
  

  

  first 
  posterior 
  cell 
  in 
  its 
  last 
  third. 
  The 
  hyaline 
  parts 
  are 
  distinctly 
  whitish 
  ; 
  

  

  the 
  dark 
  parts 
  are 
  blackish, 
  only 
  the 
  basal 
  band 
  below 
  the 
  sixth 
  vein 
  in 
  the 
  axillary 
  

  

  cell 
  being 
  more 
  greyish.

  an 
  additional 
  female 
  specimen 
  from 
  the

  1913, 
  all 
  collected 
  

   by 
  S. 
  A. 
  Neave, 
  in 
  whose 
  honour 
  this 
  interesting 
  species 
  is 
  named.

  the

  U.S.A., 
  

   there 
  is 
  a 
  female 
  specimen 
  collected 
  by 
  F. 
  L. 
  Snow 
  at 
  Salisbury, 
  Rhodesia, 
  5050 
  ft., 
  

   v. 
  1901 
  ; 
  it 
  differs 
  in 
  having 
  the 
  basal 
  hyaline 
  spot 
  of 
  the 
  discoidal 
  cell 
  of 
  greater 
  

   size, 
  extending 
  from 
  the 
  fourth 
  to 
  the 
  fifth 
  longitudinal 
  vein.

  In 
  my 
  previous 
  paper 
  (Bull. 
  Ent. 
  Res. 
  ix, 
  p. 
  22) 
  I 
  overlooked 
  this 
  species, 
  which 
  

   is 
  nearly 
  allied 
  to 
  but 
  distinct 
  from 
  T. 
  rufiventris, 
  Bezzi 
  ; 
  it 
  is 
  recorded 
  from 
  British 
  

   East 
  Africa, 
  Nairobi 
  (de 
  Rothschild).

  This 
  genus, 
  as 
  defined 
  by 
  me 
  in 
  the 
  preceding 
  paper, 
  seems 
  to 
  have 
  a 
  near 
  ally 
  

  

  in 
  the 
  South 
  American 
  genus 
  Lamproxyna, 
  Hendel 
  (1914, 
  p. 
  64), 
  which 
  shows 
  also 
  

  

  a 
  shining 
  black, 
  not 
  dusted 
  abdomen, 
  but 
  seems 
  to 
  be 
  different 
  in 
  the 
  much 
  more 
  

  

  elongate 
  and 
  bicubitate 
  proboscis, 
  in 
  the 
  antennae 
  being 
  inserted 
  below 
  the 
  middle
