  This 
  is 
  a 
  very 
  distinct 
  species, 
  though 
  in 
  its 
  thoracic 
  markings 
  it 
  resembles 
  

   0. 
  pseudotaeniatus, 
  Giles, 
  and 
  Stegomyia 
  trilineata, 
  Leic. 
  The 
  abdominal 
  markings 
  

   are 
  peculiar, 
  but 
  are 
  paralleled 
  by 
  Orthopodomyia. 
  To 
  judge 
  from 
  the 
  description 
  

   Doleschall's 
  Culex 
  aureostriatus 
  must 
  resemble 
  this 
  species 
  rather 
  closely, 
  but 
  it 
  has 
  

   the 
  white 
  bands 
  on 
  the 
  abdomen 
  at 
  the 
  apex 
  of 
  the 
  respective 
  segments. 
  

  

  Culiciomyia 
  bahri, 
  sp. 
  nov. 
  

  

  Head 
  clothed 
  with 
  black 
  upright 
  forked 
  scales 
  and 
  yellowish 
  narrow 
  curved 
  scales 
  

   in 
  the 
  middle 
  ; 
  flat 
  scales 
  at 
  the 
  sides, 
  which 
  are 
  white 
  below 
  and 
  purplish 
  black 
  

   above, 
  the 
  white 
  ones 
  however 
  extending 
  upwards 
  along 
  the 
  eye-margins 
  towards 
  the 
  

   middle 
  line, 
  but 
  they 
  do 
  not 
  as 
  in 
  other 
  members 
  of 
  the 
  genus 
  quite 
  reach 
  the 
  middle. 
  

   Basal 
  joint 
  of 
  antennae 
  blackish, 
  without 
  scales. 
  Palpi 
  and 
  proboscis 
  black-scaled. 
  

   In 
  the 
  male 
  the 
  palpi 
  are 
  longer 
  than 
  the 
  proboscis 
  by 
  a 
  little 
  more 
  than 
  

   the 
  length 
  of 
  the 
  last 
  joint, 
  the 
  penultimate 
  joint 
  is 
  only 
  a 
  little 
  shorter 
  than 
  the 
  

   terminal, 
  and 
  about 
  three 
  times 
  as 
  long 
  as 
  the 
  labella 
  ; 
  the 
  projecting 
  scales 
  on 
  the 
  

   basal 
  joints 
  are 
  much 
  fewer, 
  shorter 
  and 
  more 
  difficult 
  to 
  see 
  than 
  in 
  any 
  other 
  member 
  

   of 
  the 
  genus. 
  Thorax 
  with 
  the 
  usual 
  dull 
  (matt) 
  greyish-brown 
  integument, 
  clothed 
  

   with 
  small 
  narrow 
  dark 
  brown 
  scales, 
  lighter 
  on 
  the 
  scutellum. 
  Pleurae 
  pale, 
  un- 
  

   sealed, 
  without 
  any 
  dark 
  markings. 
  Abdomen 
  clothed 
  with 
  blackish 
  brown 
  scales 
  

   above, 
  whitish 
  ones 
  below 
  ; 
  no 
  trace 
  of 
  white 
  lateral 
  spots 
  at 
  the 
  bases 
  of 
  the 
  segments, 
  

   but 
  a 
  few 
  paler 
  scales 
  at 
  the 
  apical 
  corners. 
  Male 
  genitalia 
  with 
  spiny 
  claspers 
  and 
  

   with 
  the 
  second 
  plate 
  of 
  the 
  harpagones 
  long, 
  pointed 
  and 
  serrate 
  below, 
  as 
  in 
  all 
  other 
  

   species 
  of 
  the 
  genus. 
  Legs 
  entirely 
  dark-scaled 
  except 
  for 
  the 
  under 
  sides 
  of 
  the 
  

   femora 
  and 
  the 
  lateral 
  aspect 
  of 
  the 
  hind 
  pair. 
  Wings 
  with 
  dark 
  brown 
  scales 
  ; 
  the 
  

   lateral 
  vein-scales 
  towards 
  the 
  apex 
  of 
  the 
  wing 
  are 
  linear. 
  Fork-cells 
  rather 
  long, 
  

   the 
  upper 
  one 
  about 
  twice 
  as 
  long 
  as 
  its 
  stem 
  and 
  with 
  its 
  base 
  a 
  little 
  nearer 
  the 
  base 
  of 
  

   the 
  wing 
  than 
  that 
  of 
  the 
  lower.

  the 
  British

  The 
  specimens 
  were 
  all 
  at 
  first 
  thought 
  to 
  be 
  C. 
  fragilis, 
  Ludlow,* 
  but 
  there 
  are 
  

   abundant 
  distinctions 
  between 
  the 
  two, 
  C. 
  bahri 
  having 
  narrower 
  lateral 
  vein-scales, 
  

   fewer 
  flat 
  white 
  scales 
  on 
  the 
  orbital 
  margins, 
  fewer 
  outstanding 
  scales 
  and 
  a 
  longer 
  

   penultimate 
  joint 
  to 
  the 
  male 
  palpi, 
  and 
  in 
  the 
  genitalia 
  more 
  rounded 
  side-pieces 
  and 
  

   a 
  shorter 
  basal 
  projection 
  on 
  the 
  harpagones. 
  In 
  scale 
  characters 
  C. 
  bahri 
  resembles 
  

   Culex 
  almost 
  as 
  much 
  as 
  Culiciomyia 
  and 
  might 
  be 
  considered 
  as 
  invalidating 
  the 
  

  

  *Culicomyia 
  fragilis,

  = 
  Culex 
  fragilis,

  The 
  writer's 
  previous 
  identification 
  of 
  

   C. 
  fragilis 
  with 
  the 
  African 
  Culiciomyia

  is 
  incorrect.
