  18.vii.1918 
  (P.

   Buxton 
  : 
  presented 
  by 
  the 
  Imperial 
  Bureau 
  of 
  Entomology) 
  ; 
  paratype, 
  Ramadi, 
  

   R.

  August 
  1920 
  (Major

  Owing 
  to 
  the 
  presence 
  of 
  a 
  clear 
  " 
  window-pane 
  " 
  in 
  the 
  discal 
  cell, 
  the 
  species 
  

   described 
  above 
  belongs 
  to 
  Krober's 
  Group 
  Heterochrysops* 
  of 
  which 
  C. 
  punctifera, 
  

   Lw., 
  is 
  also 
  a 
  member. 
  From 
  a 
  second 
  representative 
  of 
  the 
  same 
  group, 
  C. 
  beckeri, 
  

   Krober 
  (loc. 
  cit., 
  p. 
  135, 
  pi. 
  ii, 
  fig. 
  60), 
  the 
  type 
  of 
  which 
  was 
  obtained 
  in 
  Turkestan, 
  

   the 
  new 
  species 
  is 
  distinguishable, 
  inter 
  alia, 
  by 
  the 
  dark 
  stripes 
  on 
  the 
  dorsum 
  of 
  

   the 
  thorax 
  being 
  somewhat 
  dull, 
  instead 
  of 
  shining 
  black 
  ; 
  by 
  the 
  narrowness 
  of 
  the 
  

   dark 
  brown 
  costal 
  border 
  on 
  the 
  wings, 
  this 
  border 
  being 
  distinctly 
  narrower 
  than 
  the 
  

   apical 
  fleck 
  instead 
  of 
  being 
  of 
  equal 
  breadth 
  ; 
  by 
  the 
  first 
  basal 
  cell 
  being 
  infuscated 
  

   (with 
  a 
  faint 
  brownish 
  smear) 
  at 
  the 
  extreme 
  base, 
  as 
  well 
  as 
  conspicuously 
  at 
  the 
  

   tip, 
  instead 
  of 
  having 
  the 
  latter 
  alone 
  brown 
  ; 
  and 
  by 
  the 
  front 
  femora 
  being 
  clothed 
  

   with 
  black 
  hairs 
  only 
  at 
  the 
  tips, 
  instead 
  of 
  on 
  the 
  lower 
  surface 
  generally. 
  

  

  Finally, 
  it 
  may 
  be 
  noted 
  that 
  a 
  solitary 
  $ 
  in 
  the 
  National 
  Collection, 
  8 
  mm. 
  in 
  

   length, 
  which 
  is 
  in 
  all 
  probability 
  to 
  be 
  assigned 
  to 
  Chrysops 
  simillima, 
  while 
  

   practically 
  identical 
  in 
  outward 
  appearance 
  with 
  the 
  $ 
  of 
  C. 
  punctifera, 
  Lw., 
  even 
  

   when 
  subjected 
  to 
  an 
  extremely 
  close 
  scrutiny, 
  is 
  nevertheless 
  distinguishable 
  owing 
  

   to 
  the 
  shape 
  of 
  the 
  shining 
  black 
  facial 
  tubercles. 
  In 
  the 
  specimen 
  referred 
  to, 
  the 
  

   areas 
  in 
  question, 
  which 
  are 
  larger 
  than 
  the 
  corresponding 
  areas 
  in 
  the 
  case 
  of 
  

   C. 
  punctifera 
  -J, 
  have 
  their 
  lower 
  margins 
  horizontal 
  (instead 
  of 
  running 
  obliquely 
  

   upwards 
  and 
  outwards), 
  so 
  that 
  the 
  angle 
  formed 
  with 
  the 
  outer 
  margin 
  in 
  each 
  case 
  

   is 
  to 
  all 
  intents 
  and 
  purposes 
  a 
  right 
  angle. 
  Besides 
  the 
  differences 
  mentioned, 
  the 
  

   lateral 
  spots 
  on 
  the 
  second 
  (visible) 
  abdominal 
  tergite, 
  in 
  addition 
  to 
  being 
  Naples 
  

   yellow 
  or 
  cream-coloured, 
  and 
  therefore 
  paler 
  than 
  is 
  usually 
  the 
  case 
  in 
  C. 
  punctifera 
  <$, 
  

   have 
  their 
  inward 
  extensions 
  narrower, 
  though 
  whether 
  these 
  features 
  are 
  constant 
  it 
  

   is 
  at 
  present, 
  of 
  course, 
  impossible 
  to 
  say. 
  The 
  $ 
  under 
  discussion 
  was 
  taken 
  at 
  Tonooma 
  

   (on 
  left 
  bank 
  of 
  Shatt

  It 
  only 
  remains 
  to 
  add 
  that 
  the 
  species 
  described 
  above 
  is 
  doubtless 
  that 
  which 
  

   is 
  referred 
  to
