  longer 
  than 
  broad 
  ; 
  chitinised 
  area 
  saddle-shaped, 
  bearing 
  at 
  its 
  posterior 
  margin 
  

   a 
  few 
  spicules 
  and 
  a 
  tuft 
  of 
  delicate 
  hairs. 
  Beard

   hairs 
  at 
  the

  Diagnosis. 
  — 
  This 
  larva 
  according 
  to 
  Edwards's 
  key 
  (Bull. 
  Ent. 
  Res. 
  iii, 
  p. 
  376) 
  

   has 
  to 
  be 
  distinguished 
  from 
  those 
  of 
  Aedes 
  {0.) 
  nigeriensis 
  and 
  Aides 
  (S.) 
  vittata, 
  

   which 
  also 
  have 
  the 
  median 
  hairs 
  on 
  the 
  head 
  single. 
  From 
  both 
  these 
  it 
  may 
  be 
  

   separated, 
  to 
  mention 
  only 
  one 
  of 
  many 
  characters, 
  by 
  the 
  number 
  of 
  scales 
  in 
  the 
  

   comb.
