  though 
  in 
  regard 
  to 
  abdominal 
  markings 
  they 
  agree 
  with 
  moderately 
  dark 
  specimens 
  

   of 
  the 
  species. 
  Nothing 
  approaching 
  this 
  variation 
  has 
  been 
  seen 
  from 
  elsewhere, 
  

   and 
  it 
  therefore 
  seems 
  justifiable 
  to 
  distinguish 
  them 
  under 
  a 
  separate 
  name. 
  It 
  

   will 
  be 
  interesting 
  to 
  find 
  whether 
  any 
  difference 
  exists 
  in 
  the 
  male.

  A 
  small 
  series 
  recently 
  received 
  from 
  Wareham 
  Heath, 
  Dorset 
  (H. 
  Scott), 
  proves 
  

   on 
  close 
  examination 
  to 
  represent 
  a 
  species 
  distinct 
  from 
  the 
  one 
  we 
  have 
  usually 
  

   known 
  as 
  dorsalis, 
  though 
  this 
  latter 
  was 
  taken 
  in 
  company 
  with 
  it 
  and 
  0. 
  salinus, 
  

   Fie. 
  The 
  two 
  forms 
  differ 
  as 
  follows 
  : 
  — 
  

  

  0. 
  caspius, 
  Pallas 
  (dorsalis, 
  auct.). 
  Scales 
  of 
  mesonotum 
  ochreous 
  brown 
  or 
  

   fawn-coloured, 
  with 
  two 
  narrow 
  white 
  lines 
  running 
  the 
  whole 
  length. 
  Scales 
  of 
  

   proboscis 
  mostly 
  pale 
  except 
  towards 
  base 
  and 
  tip. 
  Abdominal 
  scales 
  usually 
  of 
  

   three 
  colours, 
  black, 
  white 
  and 
  ochreous. 
  Wing 
  scales 
  mostly 
  rather 
  broad, 
  dark 
  

   ones 
  being 
  evenly 
  spread 
  over 
  all 
  the 
  veins, 
  though 
  in 
  varying 
  proportions 
  with 
  

   the 
  light 
  ones. 
  Dark 
  scales 
  more 
  numerous 
  on 
  the 
  femora. 
  Apical 
  part 
  of 
  basal 
  

   lobe 
  of 
  side-piece 
  of 
  male 
  genitalia 
  not 
  prominent. 
  

  

  O. 
  curriei, 
  Coq. 
  Scales 
  of 
  mesonotum 
  mostly 
  greyish 
  ochreous 
  ; 
  a 
  dark 
  brown 
  

   band 
  of 
  varying 
  width 
  in 
  the 
  middle, 
  extending 
  only 
  about 
  half 
  way 
  from 
  the 
  front 
  ; 
  

   patches 
  of 
  the 
  same 
  colour 
  on 
  each 
  side 
  in 
  front. 
  Scales 
  of 
  proboscis 
  mostly 
  black. 
  

   Abdominal 
  scales 
  of 
  two 
  colours 
  only, 
  black 
  and 
  greyish 
  white. 
  Wing 
  scales 
  mostly 
  

   quite 
  narrow 
  ; 
  at 
  the 
  base 
  of 
  the 
  wing 
  they 
  are 
  all 
  pale 
  ; 
  dark 
  ones 
  predominate 
  on 
  

   the 
  apical 
  half 
  of 
  the 
  costa, 
  on 
  the 
  first 
  longitudinal 
  vein, 
  and 
  on 
  the 
  forks 
  of 
  the 
  

   fourth, 
  while 
  on 
  the 
  third 
  and 
  fifth 
  longitudinal 
  veins 
  the 
  scales 
  are 
  almost 
  all 
  dark 
  ; 
  

   elsewhere 
  they 
  are 
  mostly 
  pale. 
  Femora, 
  except 
  towards 
  tips, 
  almost 
  all 
  pale. 
  

   Apical 
  part 
  of 
  basal 
  lobe 
  of 
  male 
  genitalia 
  prominent. 
  

  

  Meigen's 
  descriptions 
  of 
  C. 
  punctatus 
  and 
  C. 
  dorsalis 
  do 
  not 
  apply 
  very 
  well 
  either 
  

   to 
  O. 
  caspius 
  or 
  to 
  0. 
  curriei, 
  though 
  they 
  almost 
  certainly 
  must 
  refer 
  to 
  one 
  or 
  the 
  

   other, 
  and 
  perhaps 
  with 
  more 
  probability 
  to 
  the 
  latter. 
  An 
  examination 
  of 
  the 
  

   types 
  would 
  be 
  essential 
  to 
  settle 
  the 
  point. 
  

  

  The 
  British 
  examples 
  of 
  O, 
  curriei 
  only 
  differ 
  from 
  North 
  American 
  specimens 
  

   in 
  having 
  the 
  dark 
  scales 
  of 
  the 
  wings 
  rather 
  more 
  numerous, 
  especially 
  on 
  the 
  

   costa. 
  The 
  male 
  genitalia 
  are 
  identical.
