  The 
  species 
  under 
  discussion, 
  which 
  was 
  described 
  from 
  specimens 
  collected 
  by 
  

   its 
  author 
  in 
  Asia 
  Minor, 
  is 
  widely 
  distributed, 
  its 
  range 
  including 
  Algeria, 
  Persia 
  

   and 
  Afghanistan, 
  while, 
  as 
  correctly 
  pointed 
  out 
  by 
  Szilady 
  (Ent. 
  Mitt., 
  iv, 
  Nr. 
  4/6, 
  

   p. 
  98, 
  1915), 
  Tabanus 
  cyprianus, 
  Ric, 
  the 
  type 
  of 
  which 
  was 
  obtained 
  at 
  Kelopside, 
  

   Cyprus, 
  is 
  a 
  synonym. 
  The 
  specimens 
  enumerated 
  above 
  vary 
  greatly 
  in 
  size, 
  i.e., 
  

   from 
  a 
  length 
  of 
  9 
  mm. 
  in 
  the 
  case 
  of 
  a 
  2 
  taken 
  by 
  Major 
  Fraser 
  at 
  Ramadi, 
  8. 
  viii. 
  1920, 
  

   to 
  a 
  length 
  of 
  13-6 
  mm. 
  in 
  that 
  of 
  one 
  of 
  Mr. 
  Buxton's 
  22 
  from 
  Amara 
  (28. 
  v. 
  1918). 
  

   The 
  2 
  caught 
  by 
  Major 
  Fraser 
  in 
  May 
  1921, 
  between 
  Ba'qubah 
  and 
  Kizil 
  Robat, 
  

   the 
  length 
  of 
  which 
  likewise 
  exceeds 
  13 
  mm., 
  is 
  somewhat 
  abnormal, 
  since 
  the 
  front 
  

   is 
  broader 
  than 
  usual, 
  and 
  the 
  transverse 
  veins 
  in 
  the 
  wings 
  are 
  not 
  distinctly 
  infus- 
  

   cated. 
  According 
  to 
  field-notes 
  by 
  Major 
  Fraser, 
  in 
  life 
  the 
  eyes 
  of 
  thecJ 
  of 
  T. 
  puichellus 
  

   are 
  " 
  very 
  pale 
  green, 
  and 
  unhanded," 
  while 
  those 
  of 
  the 
  2 
  are 
  " 
  pale 
  green," 
  and 
  either 
  

   " 
  unhanded 
  " 
  or 
  " 
  with 
  one 
  very 
  faint 
  purplish 
  band." 
  

  

  Major 
  Patton 
  notes 
  that 
  this 
  Tabanus 
  " 
  occurs 
  all 
  along 
  the 
  River 
  Euphrates 
  " 
  ; 
  

   several 
  of 
  both 
  Mr. 
  Buxton's 
  and 
  Major 
  Fraser's 
  specimens 
  were 
  taken 
  " 
  round 
  a 
  

   lamp 
  at 
  night 
  " 
  ; 
  the 
  2 
  caught 
  by 
  Major 
  Fraser 
  at 
  Ramadi, 
  6. 
  viii. 
  1920, 
  was 
  " 
  on 
  a 
  

   mule," 
  while 
  a 
  second 
  2, 
  taken 
  by 
  the 
  same 
  collector 
  in 
  the 
  same 
  place 
  on 
  the 
  following 
  

   day, 
  bears 
  the 
  label

  In 
  a 
  note 
  attached 
  to 
  the 
  22 
  taken 
  at 
  Ramadi, 
  Major 
  Fraser 
  writes 
  : 
  "

   bronze-green,

  fairly 
  broad, 
  rather

  So 
  far 
  as 
  can 
  be 
  judged 
  from 
  a 
  comparison 
  of 
  the 
  types, 
  Tabanus 
  persis, 
  Ric, 
  

   is 
  a 
  form 
  of 
  T. 
  pulverifer, 
  Walk., 
  with 
  black 
  or 
  blackish-brown 
  antennae 
  in

   and 
  a 
  somewhat 
  wider

  It 
  may 
  be 
  added 
  that

   which 
  are

  Museum
