  CAMERON, 
  Hymenoptera 
  Orientalia. 
  

  

  the 
  two 
  uniting 
  into 
  one 
  above 
  the 
  antennae 
  and 
  forming 
  

   a 
  large, 
  somewhat 
  heart-shaped, 
  area 
  ; 
  a 
  stouter, 
  broader, 
  

   blunter 
  keel 
  runs 
  from 
  between 
  the 
  middle 
  of 
  the 
  ocelli 
  

   obliquely 
  to 
  the 
  eyes 
  ; 
  the 
  front 
  broadly 
  projects 
  between 
  

   the 
  antennae 
  ; 
  and 
  from 
  between 
  them 
  a 
  broad 
  furrow, 
  about 
  

   three 
  times 
  as 
  long 
  as 
  broad, 
  runs 
  down 
  the 
  face, 
  Thorax 
  

   black 
  ; 
  the 
  pro- 
  and 
  meso-thorax 
  shining, 
  impunctate. 
  

   The 
  depression 
  at 
  the 
  base 
  of 
  the 
  scutellum 
  is 
  wide 
  and 
  

   deep 
  ; 
  in 
  its 
  centre 
  is 
  a 
  stout 
  longitudinal 
  keel, 
  bordered 
  

   on 
  either 
  side 
  lower 
  down 
  by 
  a 
  thinner 
  one 
  ; 
  the 
  post- 
  

   scutellum 
  is 
  placed 
  much 
  lower 
  down 
  than 
  the 
  scutellum 
  ; 
  

   is 
  hollow, 
  wider 
  than 
  its 
  length 
  and 
  ends 
  in 
  the 
  middle 
  at 
  

   the 
  apex 
  in 
  a 
  stout 
  keel. 
  The 
  depression 
  at 
  the 
  base 
  of 
  

   the 
  median 
  segment 
  is 
  wide 
  and 
  deep 
  ; 
  the 
  segment, 
  

   except 
  at 
  the 
  base, 
  is 
  thickly 
  covered 
  with 
  longish, 
  dark 
  

   hair 
  ; 
  in 
  the 
  middle 
  is 
  one 
  continuous 
  area, 
  narrow 
  at 
  the 
  

   base, 
  becoming 
  gradually 
  wider 
  to 
  the 
  apex, 
  which 
  

   is 
  rounded 
  ; 
  in 
  it, 
  before 
  the 
  middle, 
  are 
  two 
  transverse, 
  

   not 
  very 
  stout 
  or 
  distinct, 
  keels 
  ; 
  the 
  upper 
  lateral 
  area 
  is 
  

   a 
  little 
  wider 
  than 
  long, 
  almost 
  square 
  ; 
  in 
  its 
  outer 
  side 
  

   is 
  a 
  depression 
  which 
  extends 
  from 
  top 
  to 
  bottom, 
  be- 
  

   coming 
  gradually 
  narrower 
  as 
  it 
  does 
  so. 
  Propleuroe 
  

   deeply 
  excavated, 
  especially 
  in 
  the 
  centre 
  beneath, 
  which 
  

   bears 
  in 
  the 
  middle 
  of 
  the 
  hollow, 
  some 
  stout, 
  transverse 
  

   keels 
  ; 
  the 
  mesopleurae 
  at 
  the 
  base 
  beneath 
  has 
  a 
  deep 
  

   depression, 
  wide 
  at 
  the 
  bottom, 
  narrow 
  at 
  the 
  top 
  ; 
  where 
  

   it 
  curves 
  round 
  to 
  near 
  the 
  middle 
  ; 
  in 
  the 
  narrow 
  top 
  part 
  

   arc 
  three 
  stout, 
  transverse 
  keels 
  ; 
  the 
  upper 
  two 
  of 
  which 
  

   are 
  nearer 
  to 
  each 
  than 
  the 
  lower 
  pair 
  are 
  to 
  each 
  other 
  ; 
  

   in 
  the 
  curved 
  lower 
  part 
  are 
  two 
  distinct 
  septa, 
  forming 
  two 
  

   large 
  distinct 
  foveae 
  ; 
  the 
  lower 
  being 
  the 
  larger 
  and 
  deeper. 
  

   The 
  metapleuroe 
  are 
  broadly 
  raised 
  in 
  the 
  middle, 
  the 
  raised 
  

   part 
  very 
  rough 
  ; 
  irregularly 
  reticulated 
  ; 
  its 
  apical 
  part 
  

   deeply 
  depressed, 
  the 
  depression 
  divided 
  in 
  the 
  middle 
  by
