  Petiole 
  

   as 
  long 
  as 
  the 
  second 
  and 
  third 
  segments 
  united

  from 
  

   the 
  middle 
  it 
  becomes 
  gradually 
  dilated;

   part 
  keeled 
  to 
  the 
  end 
  ; 
  the 
  gastrocceli

  joints 
  of 
  the

  broadly 
  depressed 
  behind 
  ; 
  its 
  base 
  has 
  an 
  oblique 
  

   slope, 
  and 
  is 
  keeled 
  on 
  the 
  top. 
  The 
  antennae 
  are 
  placed 
  

   high 
  up 
  on 
  the 
  face, 
  opposite 
  the 
  eye 
  incision 
  ; 
  above 
  them, 
  

   on 
  the 
  lower 
  part 
  of 
  the 
  front, 
  is 
  a 
  distinct 
  projection 
  

   which 
  is 
  widened 
  above 
  ; 
  the 
  top 
  deeply 
  depressed 
  in 
  the 
  

   middle 
  ; 
  the 
  labrum 
  is 
  not 
  exserted.

  the 
  second 
  to 
  fourth 
  segments 
  equal 
  

   in 
  length. 
  The 
  basal 
  joint 
  of 
  the 
  anterior 
  tarsi 
  is 
  incised 
  

   at 
  the 
  base 
  ; 
  the 
  apical 
  joint 
  is 
  as 
  long 
  as 
  the 
  basal 
  ; 
  the 
  

   middle 
  ones 
  short 
  and 
  thick 
  ;

  Belongs 
  to 
  the

  and 
  comes 
  near

  distinct 
  from 
  anything
