  Orientalia. 
  

  

  centre 
  of 
  the 
  petiole 
  raised 
  ; 
  the 
  sides 
  carinate. 
  The 
  

   tranverse 
  cubital 
  nervures 
  converge, 
  but 
  do 
  not 
  touch 
  

   above 
  ; 
  the 
  first 
  is 
  oblique, 
  straight 
  ; 
  the 
  second 
  is 
  oblique 
  

   above 
  and 
  thicker 
  than 
  below. 
  

  

  It 
  is 
  doubtful 
  if 
  this 
  can 
  be 
  regarded 
  as 
  a 
  Disophrys 
  

   inasmuch 
  as 
  the 
  branch 
  on 
  the 
  transverse 
  cubital 
  nervure 
  

   can 
  hardly 
  be 
  said 
  to 
  exist 
  ; 
  in 
  other 
  respects 
  it 
  agrees 
  

   fairly 
  well 
  with 
  the 
  genus.

   areolet 
  not 
  separated 
  from 
  the 
  praediscoidal 
  ; 
  the

   transverse 
  cubital 
  nervure

  with 
  a 
  wide 
  

   striolated 
  furrow. 
  Metanotum 
  irregularly 
  reticulated

  its 
  

   sides 
  at 
  the

  triangularly 
  produced.

  narrower 
  than 
  the 
  thorax 
  ; 
  eyes 
  prominent, 
  

   parallel, 
  not 
  reaching 
  to 
  the 
  clypeal 
  foveae 
  ; 
  face 
  broadly 
  

   carinate, 
  not 
  separated 
  from 
  the 
  clypeus 
  by 
  a 
  suture; 
  the 
  

   hollowed 
  part 
  of 
  the 
  front 
  is 
  bordered 
  by 
  a 
  distinct 
  stout 
  

   keel

  the 
  ocellar 
  region 
  is 
  raised; 
  theocciput 
  is 
  not 
  margined. 
  

   The 
  thorax 
  is 
  largely 
  developed 
  in 
  front 
  of 
  the 
  tegulae 
  ; 
  

   the 
  propleurae 
  are 
  deeply 
  excavated 
  on 
  the 
  lower 
  part 
  ; 
  

   the 
  mesosternum 
  broadly 
  excavated. 
  There 
  is 
  a 
  large, 
  

   clearly 
  defined 
  area 
  in 
  the

  the 
  median 
  segment, 
  

   which 
  is 
  triangular 
  at 
  the 
  base.
