  CAMERON, 
  Hymenoptera 
  Orientalia. 
  

  

  transverse 
  band, 
  incised 
  in 
  the 
  middle 
  at 
  the 
  apex 
  ; 
  the 
  

   oblique 
  furrows 
  on 
  the 
  last 
  segment, 
  narrow, 
  deep 
  and 
  

   distinct. 
  

  

  The 
  following 
  species 
  is 
  probably 
  related 
  to 
  the 
  fore- 
  

   going 
  group. 
  The 
  colour 
  of 
  the 
  abdomen 
  and 
  legs 
  is 
  

   doubtful, 
  as 
  the 
  ferruginous 
  tint 
  of 
  the 
  abdomen 
  and 
  legs 
  

   may 
  be 
  caused 
  by 
  chemical 
  discoloration 
  ; 
  but 
  structurally 
  

   it 
  is 
  distinct 
  from 
  any 
  of 
  the 
  yellow 
  species. 
  The 
  scutellum 
  

   is 
  more 
  distinctly 
  keeled 
  at 
  the 
  apex 
  than 
  in 
  the 
  yellow 
  

   species, 
  the 
  apical 
  and 
  the 
  lateral 
  keels 
  being 
  continuous.

   former 
  with 
  three 
  large, 
  almost 
  united, 
  marks 
  between 
  the 
  

   tegulae,

  down 
  the

  and 
  round 
  the

  ; 
  

   the 
  scutellum, 
  rounded 
  from 
  the

  but 
  its 
  apex 
  con- 
  

   siderably

  broader 
  than 
  they 
  are 
  long, 
  and 
  triangularly 
  

   narrowed 
  at 
  the 
  apex 
  ;

  centre 
  a 
  curved 
  keel 
  runs
