  SUDILA 
  FUSCIPENNIS, 
  Sp. 
  120V. 
  

  

  Long. 
  10 
  mm. 
  S 
  . 
  

  

  Hab. 
  Ceylon 
  (Rothney). 
  

  

  This 
  species 
  differs 
  markedly 
  from 
  the 
  preceding 
  

   in 
  the 
  form 
  of 
  the 
  head; 
  it 
  is 
  not 
  so 
  shining; 
  the 
  apex 
  of 
  

   the 
  clypeus, 
  instead 
  of 
  ending 
  in 
  the 
  middle 
  in 
  two 
  sharp 
  

   teeth, 
  has 
  only 
  a 
  semicircular 
  incision, 
  the 
  edges 
  of 
  which 
  

   do 
  not 
  project; 
  the 
  lower 
  part 
  of 
  the 
  head 
  at 
  the 
  sides 
  has 
  

   the 
  projecting 
  part 
  not 
  quite 
  so 
  lengthened, 
  and 
  is 
  sharper 
  

   pointed 
  at 
  the 
  apex 
  ; 
  the 
  apex 
  of 
  the 
  mandible 
  is 
  rounded 
  

   in 
  .S. 
  bidentata, 
  here 
  it 
  is 
  distinctly 
  transverse 
  and 
  not 
  so 
  

   much 
  narrowed; 
  another 
  marked 
  distinction 
  is 
  found 
  in 
  

   the 
  median 
  segment; 
  here 
  its 
  sides 
  are 
  bordered 
  by 
  a 
  

   furrow, 
  which 
  is 
  hardly 
  visible 
  in 
  the 
  other; 
  the 
  legs 
  are 
  

   distinctly 
  fuscous, 
  or 
  rather 
  piceous 
  ; 
  the 
  wings 
  are 
  dis- 
  

   tinctly 
  smoky, 
  being 
  much 
  darker 
  coloured 
  than 
  in 
  5. 
  

   bidentata; 
  the 
  second 
  cubital 
  cellule 
  is 
  perceptibly 
  shorter 
  

   above 
  and 
  beneath 
  than 
  the 
  third 
  ; 
  the 
  two 
  being 
  conse- 
  

   quently 
  together 
  shorter 
  than 
  the 
  first; 
  the 
  second 
  trans- 
  

   verse 
  cubital 
  nervure 
  is 
  straight, 
  more 
  oblique 
  and 
  more 
  

   narrowed 
  towards 
  the 
  first 
  at 
  the 
  top. 
  

  

  If 
  I 
  had 
  only 
  5. 
  bidentata 
  to 
  deal 
  with, 
  I 
  should 
  have 
  

   inferred 
  that 
  the 
  female 
  described 
  below 
  was 
  its 
  female 
  ; 
  

   but 
  having 
  two 
  undoubted 
  males 
  of 
  distinct 
  species, 
  I 
  am 
  

   unable 
  to 
  say 
  to 
  which 
  of 
  them 
  it 
  belongs, 
  if 
  indeed 
  it 
  

   may 
  not 
  pertain 
  to 
  a 
  third 
  unknown 
  male. 
  I 
  therefore 
  

   am 
  compelled 
  to 
  treat 
  it 
  as 
  a 
  separate 
  species.
