  a 
  small

  shallow 
  antennal 
  grooves, 
  

   and

  Palpi 
  and 
  proboscis 
  dirty 
  yellowish, 
  

   the 
  former 
  dilated 
  at 
  the 
  end, 
  the 
  latter 
  short 
  and 
  thick. 
  Cephalic 
  bristles 
  missing 
  

   in 
  the 
  type, 
  but 
  judging 
  by 
  the 
  insertion 
  points 
  there 
  are 
  two 
  s. 
  or. 
  and 
  three 
  equally 
  

   distant 
  i. 
  or. 
  Thorax 
  entirely 
  shining 
  black, 
  not 
  dusted 
  on 
  the 
  back 
  ; 
  scutellum 
  

   similar, 
  triangular, 
  flat 
  above 
  ; 
  pubescence 
  and 
  bristles 
  abraded 
  in 
  the 
  type, 
  but 
  the 
  

   mpl. 
  and 
  st. 
  are 
  present 
  on 
  one 
  side 
  and 
  are 
  black 
  ; 
  the 
  scutellum 
  has 
  certainly 
  

   four 
  bristles 
  ; 
  the 
  dc. 
  are 
  placed 
  very 
  near 
  the 
  suture. 
  Squamulae 
  brownish 
  ; 
  

   halteres 
  black. 
  Abdomen 
  entirely 
  shining 
  black, 
  with 
  short 
  black 
  pubescence 
  

   and 
  black 
  bristles 
  at 
  the 
  end 
  ; 
  ovipositor 
  shining 
  black, 
  triangular, 
  flat, 
  pro- 
  

   portionally 
  short 
  ; 
  apical 
  segment 
  reddish 
  ; 
  venter 
  black. 
  Legs 
  with 
  shining 
  

   black 
  femora 
  ; 
  front 
  tibiae 
  entirely, 
  four 
  posterior 
  ones 
  on 
  the 
  apical 
  half, 
  whitish, 
  

   like 
  the 
  whole 
  of 
  the 
  tarsi. 
  Wings 
  rather 
  broad, 
  with 
  the 
  membrane 
  shining 
  and 
  

   iridescent, 
  chiefly 
  on 
  the 
  hyaline 
  parts 
  ; 
  costa 
  and 
  veins 
  black, 
  but 
  whitish 
  on 
  the 
  

   hyaline 
  parts. 
  First 
  longitudinal 
  vein 
  short, 
  the 
  stigma 
  being 
  about 
  as 
  long 
  as 
  broad 
  

   at 
  base 
  ; 
  second 
  vein 
  straight 
  ; 
  third 
  vein 
  bristly 
  to 
  the 
  small 
  cross-vein, 
  bent 
  

   downwards 
  beyond 
  middle 
  of 
  its 
  last 
  portion 
  ; 
  last 
  portion 
  of 
  the 
  fourth 
  vein 
  curved 
  

   and 
  slightly 
  diverging 
  from 
  the 
  third 
  ; 
  small 
  cross- 
  vein 
  beyond 
  the 
  middle 
  of 
  the 
  

   discoidal 
  cell 
  ; 
  hind 
  cross- 
  vein 
  straight 
  and 
  perpendicular, 
  a 
  little 
  longer 
  than 
  

   its 
  distance 
  from 
  the 
  small 
  one 
  ; 
  lower 
  angle 
  of 
  the 
  anal 
  cell 
  narrow 
  and 
  shortly 
  

   produced. 
  The 
  blackish 
  pattern 
  is 
  very 
  like 
  that 
  of 
  A. 
  caesio, 
  or 
  of 
  the 
  Formosan

  (Zool. 
  Jahrb. 
  xxxi, 
  1911, 
  p. 
  428, 
  fig. 
  J) 
  ; 
  but 
  it 
  differs 
  in 
  

   having 
  more 
  than 
  the 
  basal 
  half 
  of 
  the 
  wing 
  entirely 
  blackish, 
  without 
  any 
  hyaline 
  

   indentation 
  of 
  the 
  fore 
  border 
  before 
  the 
  stigma, 
  and 
  without 
  any 
  hyaline 
  spot 
  or 
  

   streak 
  in 
  the 
  discoidal 
  or 
  third 
  posterior 
  cells 
  ; 
  only 
  the 
  axillary 
  lobe 
  is 
  hyaline. 
  

   The 
  stigma 
  is 
  deeper 
  black 
  than 
  the 
  surrounding 
  parts. 
  The 
  first 
  ny 
  aline 
  indenta- 
  

   tion 
  of 
  the 
  fore 
  border 
  beyond 
  the 
  stigma 
  is 
  as 
  in 
  caesio 
  ; 
  the 
  second 
  likewise, 
  but 
  

   ending 
  with 
  a 
  narrow 
  point 
  on 
  the 
  fourth 
  longitudinal 
  vein, 
  without 
  entering 
  the 
  

   discoidal 
  cell. 
  The 
  two 
  hyaline 
  apical 
  indentations 
  of 
  the 
  hind 
  border 
  are 
  as 
  in 
  

   caesio, 
  the 
  black 
  streak 
  between 
  them 
  being 
  complete 
  and 
  not 
  interrupted 
  at 
  

   base 
  (differing 
  thus 
  from 
  that 
  of 
  fossata 
  and 
  fossataeformis, 
  in 
  which 
  it 
  is 
  

   isolated).
