  The 
  specific 
  name 
  has 
  been 
  chosen 
  to 
  indicate 
  the 
  deceptive 
  resemblance 
  to 
  C. 
  

   invidiosus 
  and 
  C. 
  perfuscus.

  Culex 
  pruina, 
  Theo. 
  

  

  The 
  hypopygium 
  of 
  this 
  species 
  (which 
  is 
  not 
  illustrated) 
  is 
  very 
  characteristic, 
  

   on 
  account 
  of 
  the 
  short 
  thick 
  harpes, 
  the 
  basal 
  projection 
  of 
  which 
  is 
  very 
  broad 
  and 
  

   short, 
  much 
  broader 
  than 
  it 
  is 
  long. 
  The 
  harpagones 
  are 
  fairly 
  simple 
  in 
  structure, 
  

   and 
  appear 
  not 
  to 
  be 
  split 
  into 
  two 
  distinct 
  divisions 
  as 
  in 
  most 
  of 
  the 
  species 
  illus- 
  

   trated 
  in 
  this 
  paper.

  An 
  examination 
  of 
  the 
  hypopygium 
  of 
  the 
  single 
  male 
  specimen 
  in 
  the 
  British 
  

   Museum 
  collection 
  revealed 
  the 
  fact 
  that 
  in 
  the 
  structure 
  of 
  the 
  side-pieces 
  and 
  harpes 
  

   it 
  closely 
  resembles 
  a 
  typical 
  Culex. 
  This 
  is 
  most 
  surprising 
  as 
  the 
  thoracic 
  orna- 
  

   mentation 
  is 
  so 
  very 
  different 
  from 
  that 
  of 
  all 
  other 
  known 
  species 
  of 
  the 
  genus. 
  

   Unfortunately 
  the 
  specific 
  name 
  Uneatus 
  has 
  already 
  been 
  used 
  in 
  Culex, 
  so 
  that 
  now 
  

   this 
  species 
  is 
  transferred 
  to 
  its 
  proper 
  genus 
  it 
  requires 
  renaming. 
  

  

  In 
  addition 
  to 
  the 
  five 
  species 
  of 
  Culex 
  just 
  described 
  as 
  new, 
  the 
  following 
  

   apparently 
  new 
  species 
  (three 
  and 
  two 
  varieties 
  from 
  the 
  Ethiopian, 
  eight 
  from 
  the 
  

   Oriental 
  Region) 
  have 
  at 
  various 
  times 
  come 
  to 
  the 
  writer's 
  notice. 
  The 
  types 
  of 
  

   all 
  are 
  in 
  the 
  British 
  Museum, 
  and 
  unless 
  otherwise 
  stated 
  have 
  been 
  presented 
  

   by 
  the 
  collectors.

  nov. 
  

  

  Head 
  with 
  narrow 
  curved 
  scales 
  in 
  the

  bright 
  yellow, 
  with 
  a 
  small 
  patch 
  

   of 
  dark 
  brown 
  ones 
  in 
  front 
  ; 
  flat 
  scales 
  at 
  the 
  sides, 
  mostly 
  dark 
  brown, 
  but 
  a 
  small 
  

   stripe 
  of 
  yellow 
  ones 
  in 
  the 
  middle 
  of 
  the 
  dark 
  patch. 
  Basal 
  joint 
  of 
  antennae

  of 
  palpi 
  and 
  proboscis 
  all 
  dark 
  brown 
  ; 
  male 
  palpi 
  

   longer 
  than 
  the 
  proboscis 
  by 
  nearly 
  the 
  length 
  of 
  the 
  second 
  (last) 
  joint, 
  which 
  is 
  quite 
  

   five 
  times 
  as 
  long 
  as 
  the 
  labella. 
  Thorax 
  dark 
  brown, 
  with

  dark 
  brown 
  and 
  

   yellow 
  scales,

  not 
  forming 
  a 
  definite 
  

   yellow 
  stripe 
  as 
  in 
  B. 
  luteolateralis. 
  Abdomen 
  dark 
  brown

  each 
  segment 
  with 
  

   lateral 
  basal 
  yellowish 
  spots, 
  those 
  on 
  segments 
  5-7 
  slightly 
  expanded 
  towards 
  the 
  

   middle 
  of 
  the 
  segments 
  and 
  thus 
  visible 
  from 
  above. 
  Venter 
  yellowish, 
  with 
  apical 
  

   dark

  but 
  the

  much 
  sw 
  T 
  ollen 
  in 
  the 
  middle. 
  Legs 
  entirely 
  clothed 
  with 
  dark

  of 
  the 
  femora.
