  Orientalia. 
  

  

  ocellus, 
  where 
  it 
  bifurcates 
  ; 
  from 
  the 
  side 
  of 
  the 
  fore 
  ocellus 
  

   a 
  narrower 
  keel 
  runs 
  to 
  the 
  side, 
  uniting 
  with 
  the 
  larger 
  

   keel 
  before 
  the 
  eyes 
  ; 
  the 
  space 
  between 
  the 
  keel 
  and 
  the 
  

   eyes 
  is 
  stoutly 
  crenulated. 
  On 
  the 
  upper 
  half 
  of 
  the 
  eyes, 
  

   but 
  not 
  touching 
  them, 
  is 
  a 
  narrow 
  furrow 
  ; 
  behind, 
  on 
  the 
  

   upper 
  half 
  is 
  a 
  much 
  wider, 
  deeper, 
  crenulated 
  furrow 
  ; 
  

   the 
  lower 
  part 
  of 
  the 
  eyes 
  on 
  the 
  inner 
  and 
  apical 
  side 
  is 
  

   distinctly 
  margined 
  by 
  a 
  keel. 
  Antennae 
  black, 
  the 
  scape 
  

   slightly, 
  the 
  flagellum 
  broadly, 
  testaceous 
  beneath. 
  Thorax 
  

   black, 
  with 
  a 
  greenish 
  tinge 
  ; 
  the 
  mesonotum 
  shagreened 
  ; 
  

   a 
  fine 
  transverse 
  furrow 
  at 
  the 
  base 
  of 
  the 
  scutellum 
  ; 
  

   down 
  the 
  centre 
  of 
  the 
  mesonotum 
  are 
  two 
  wide 
  furrows 
  

   which 
  slightly 
  converge 
  towards 
  the 
  scutellum 
  and 
  are, 
  

   towards 
  the 
  apex, 
  slightly 
  crenulated 
  ; 
  in 
  the 
  centre 
  are 
  

   two 
  obscure 
  longitudinal 
  furrows; 
  and, 
  outside 
  the 
  central, 
  

   there 
  are 
  two 
  narrower, 
  complete 
  furrows, 
  which 
  are 
  dis- 
  

   tinctly 
  curved 
  towards 
  the 
  base 
  of 
  the 
  thorax. 
  At 
  the 
  

   base 
  of 
  the 
  scutellum 
  there 
  is 
  a 
  wide, 
  deep, 
  straight 
  furrow 
  

   behind 
  the 
  narrower 
  one. 
  Scutellum 
  large, 
  indistinctly 
  

   keeled 
  down 
  the 
  middle 
  ; 
  the 
  sides 
  straight, 
  distinctly 
  

   margined 
  ; 
  post-scutellum 
  distinct; 
  the 
  sides 
  obliquely 
  

   truncated 
  towards 
  the 
  apex. 
  Median 
  segment 
  with 
  a 
  

   decided 
  coppery-greenish 
  tint 
  ; 
  the 
  base 
  completely 
  areo- 
  

   lated 
  ; 
  all 
  the 
  areae 
  being 
  distinctly 
  defined 
  ; 
  the 
  middle 
  

   portion 
  is 
  entirely 
  occupied 
  by 
  a 
  deep 
  pentagonal 
  area, 
  

   wider 
  than 
  long 
  and, 
  of 
  which, 
  the 
  apex 
  is 
  rounded 
  

   inwardly; 
  down 
  its 
  centre 
  is 
  a 
  narrow 
  furrow, 
  and 
  near 
  its 
  

   apex 
  are 
  two 
  stout, 
  transverse, 
  somewhat 
  curved 
  keels 
  ; 
  

   the 
  apex 
  itself 
  is 
  perpendicular 
  and 
  transversely 
  roughened. 
  

   In 
  front 
  of 
  the 
  tegulae 
  are 
  two 
  or 
  three 
  stout 
  keels, 
  and 
  

   inside 
  of 
  these 
  a 
  few 
  large, 
  round 
  punctures. 
  Wings 
  clear 
  

   hyaline, 
  the 
  stigma 
  fuscous, 
  paler 
  above 
  ; 
  the 
  costa 
  in 
  front 
  of 
  

   it 
  fuscous, 
  the 
  rest 
  of 
  it 
  and 
  the 
  nervures 
  yellow 
  ; 
  the 
  second 
  

   cubital 
  nervure 
  narrowed 
  on 
  the 
  lower 
  side 
  ; 
  the 
  second 
  

   recurrent 
  nervure 
  almost 
  interstitial.
