  the 
  mandibles 
  broadly 
  at 
  the 
  base, 
  rufo-testaceous 
  ; 
  the 
  

   palpi 
  yellow; 
  the 
  face 
  strongly 
  punctured 
  ; 
  the 
  punctures 
  

   large, 
  deep, 
  and 
  clearly 
  separated 
  ; 
  the 
  front 
  and 
  vertex 
  

   smooth 
  and 
  shining, 
  sparsely 
  and

  ; 
  the 
  mesopleurae 
  finely 
  punctured; 
  

   the

  excavated. 
  

   Mesosternum 
  thickly 
  covered 
  with 
  long 
  fuscous 
  hair 
  ; 
  its 
  

   middle 
  depressed. 
  On 
  the 
  metapleurae, 
  enclosing 
  the 
  

   spiracles, 
  are 
  two 
  curved 
  longitudinal 
  keels, 
  which 
  con- 
  

   verge 
  towards 
  the 
  apex 
  ; 
  the 
  distance 
  between 
  them 
  at 
  

   the 
  base 
  being 
  greater 
  than

  knees, 
  basal 
  half 
  of 
  

   tibiae 
  and

  TlLGIDA,

  Fore 
  wings 
  without 
  an 
  areolet, 
  the 
  only 
  transverse 
  

   cubital 
  nervure 
  very 
  short, 
  so 
  that 
  the 
  cubital 
  and 
  the 
  

   radial 
  nervures 
  approach 
  each 
  other 
  very 
  closely 
  ; 
  the 
  

   recurrent 
  nervure 
  is 
  received 
  about 
  four 
  times 
  its 
  length 
  

   from 
  it 
  ; 
  the 
  transverse 
  median 
  is 
  received 
  shortly 
  behind 
  

   the 
  transverse 
  basal. 
  Eyes 
  very 
  large, 
  their 
  inner 
  orbits 
  

   straight 
  and 
  converging 
  slightly, 
  but 
  distinctly, 
  on 
  the 
  

   lower 
  side 
  ; 
  the 
  orbits 
  are 
  very 
  little 
  developed 
  behind, 
  

   and 
  are 
  roughly 
  striated 
  above. 
  Clypeus 
  small, 
  its 
  apex 
  

   transverse 
  ; 
  the 
  labrum 
  is 
  longer 
  than 
  it.
