  orientalis, 
  Smith, 
  (PI. 
  X.,

  14, 
  a,

  The 
  largest 
  of 
  the 
  oriental 
  species. 
  In 
  the 
  only 
  example 
  

   I 
  have 
  seen 
  the 
  ocelli 
  are 
  in 
  a 
  black 
  patch 
  ; 
  and 
  the 
  sternum 
  

   is 
  also 
  black. 
  The 
  posterior 
  ocelli 
  are 
  separated 
  from 
  the 
  

   eyes 
  by 
  fully 
  the 
  length 
  of 
  the 
  second 
  and 
  third 
  joints 
  

   united 
  ; 
  and 
  from 
  each 
  other 
  by 
  the 
  length 
  of 
  the 
  fourth. 
  

   Trigonal 
  area 
  broad, 
  coarsely 
  aciculate. 
  Petiole 
  broader 
  

   than 
  long. 
  Pygidial 
  area 
  narrowed 
  a 
  little 
  at 
  base 
  and 
  apex 
  ; 
  

   the 
  apex 
  rounded 
  ; 
  the 
  hair-fringe 
  dense 
  pale 
  fulvous 
  ; 
  

   incision 
  in 
  hypopygium 
  reaching 
  near 
  to 
  the 
  middle 
  ; 
  there 
  

   is 
  a 
  tuft 
  of 
  hairs 
  on 
  the 
  apex 
  of 
  the 
  segment 
  at 
  the 
  sides. 
  

   The 
  second 
  cubital 
  cellule 
  forms 
  almost 
  a 
  semi-circle 
  ; 
  and 
  

   receives 
  the 
  recurrent 
  nervure 
  near 
  the 
  middle.

  Eyes 
  slightly 
  diverging 
  beneath. 
  Ocelli 
  hardly 
  forming 
  

   a 
  triangle 
  ; 
  the 
  posterior 
  separated 
  from 
  the 
  eyes 
  by 
  fully 
  

   the 
  length 
  of 
  the 
  third 
  antennal 
  joint, 
  and 
  by 
  the 
  length 
  of 
  

   the 
  fourth 
  from 
  each 
  other. 
  Clypeus 
  flat, 
  the 
  middle 
  at 
  the 
  

   apex 
  turned 
  outwardly, 
  widely 
  semi-circularly 
  incised 
  and 
  

   separated 
  from 
  the 
  lateral 
  pieces 
  by 
  projecting 
  beyond 
  

   them. 
  Head 
  closely 
  rugosely 
  punctured 
  ; 
  the 
  cheeks 
  and 
  

   lateral 
  margin 
  of 
  clypeus 
  densely 
  covered 
  with 
  silvery 
  white 
  

   hair. 
  Mesonotum 
  closely 
  and 
  finely 
  longitudinally 
  rugosely 
  

   punctured 
  ; 
  the 
  pleurae 
  coarsely 
  rugose 
  ; 
  trigonal 
  area 
  

   finely 
  rugose. 
  Abdomen 
  twice 
  the 
  length 
  of 
  the 
  thorax, 
  and 
  

   narrower 
  than 
  it 
  ; 
  the 
  petiole 
  not 
  much 
  broader 
  than 
  long 
  ; 
  

   the 
  punctuation 
  of 
  the 
  segments 
  not 
  very 
  strong 
  ; 
  the 
  

   pygidial 
  area 
  closely 
  rugose, 
  hardly 
  narrowed 
  at 
  the 
  base 
  ; 
  

   the 
  apex 
  transverse 
  : 
  the 
  incision 
  on 
  hypopygium 
  longer 
  

   than 
  broad 
  ; 
  rounded 
  at 
  the 
  base, 
  dilated 
  at 
  the 
  apex. 
  The 
  

   third 
  joint 
  of 
  antennae 
  longer 
  and 
  thinner 
  than 
  the 
  fourth. 
  

   The 
  cheeks, 
  clypeus, 
  orbits 
  broadly 
  above 
  the 
  base 
  of 
  the 
  

   antennae 
  ; 
  a 
  spot 
  behind 
  the 
  eyes 
  near 
  the 
  top, 
  a 
  band 
  on
