  Male 
  hypopygium 
  : 
  claspers 
  much 
  expanded 
  apically 
  and 
  bearing 
  a 
  comb 
  which 
  

   consists 
  of 
  one 
  long 
  tooth 
  (at 
  the 
  apical 
  end) 
  and 
  about 
  thirteen 
  shorter 
  ones 
  ; 
  basal 
  

   lobes 
  of 
  side-pieces 
  with 
  three 
  long 
  teeth 
  .; 
  a 
  patch 
  of 
  scales 
  on 
  the 
  inner 
  dorsal 
  margin 
  

   of 
  each 
  side-piece 
  near 
  the 
  base. 
  

  

  Larva 
  of 
  the 
  Armigeres 
  type 
  ; 
  elongate, 
  whitish. 
  Antennae 
  short, 
  cylindrical, 
  

   the 
  tuft 
  represented 
  by 
  a 
  single 
  hair 
  situated 
  at 
  J. 
  Head 
  tufts 
  small 
  ; 
  of 
  the 
  two 
  

   median 
  pairs 
  one 
  consists 
  of 
  two 
  hairs, 
  the 
  other 
  of 
  three. 
  Comb 
  of 
  eighth 
  segment 
  

   with 
  about 
  10 
  scales. 
  Siphon 
  about 
  as 
  broad 
  as 
  long 
  ; 
  no 
  trace 
  of 
  a 
  pecten 
  ; 
  the 
  

   small 
  two-haired 
  tuft 
  situated 
  a 
  little 
  beyond 
  the 
  middle.

   bred 
  from 
  larvae 
  in 
  bamboo 
  stumps 
  (E.

  L. 
  omissa 
  much 
  resembles, 
  and 
  may 
  be 
  a 
  variety 
  of, 
  L. 
  dolicocephala, 
  Leic, 
  the 
  only 
  

   difference 
  being 
  the 
  absence 
  of 
  yellow 
  lateral 
  spots 
  on 
  segments 
  2-5 
  of 
  the 
  abodmen. 
  

   In 
  other 
  instances 
  similar 
  differences 
  have 
  been 
  proved 
  to 
  be 
  specific, 
  and 
  they 
  are 
  

   therefore 
  accepted 
  as 
  such 
  in 
  the 
  present 
  case. 
  Unfortunately 
  the 
  male 
  genitalia 
  of 
  

   L. 
  dolicocephala 
  have 
  not 
  been 
  described. 
  L. 
  omissa 
  approaches 
  the 
  genus 
  Armigeres 
  

   in 
  the 
  greater 
  number 
  of 
  teeth 
  in 
  the 
  claspers.

  1900 
  (Lt.-Col.

  The 
  specimen 
  was 
  Giles' 
  <J 
  type 
  of 
  Stegomyia 
  pipersalata, 
  but 
  since 
  that 
  name 
  has 
  

   been 
  restricted 
  to 
  the 
  female, 
  Giles' 
  type 
  (J, 
  which 
  belongs 
  to 
  quite 
  a 
  different 
  species, 
  

   requires 
  re-naming. 
  It 
  could 
  not 
  possibly 
  be 
  confused 
  with 
  any 
  other 
  Oriental 
  species.
