  Antennae 
  11- 
  jointed,

  just 
  below 
  the 
  middle 
  of 
  the 
  face 
  ; 
  the 
  scape 
  

   long 
  and 
  slender 
  ; 
  pedicel 
  short, 
  followed 
  by 
  two 
  ring 
  joints 
  ; 
  first 
  funicular 
  joint 
  

   much 
  expanded, 
  joints 
  6-8 
  cylindrical, 
  the 
  last 
  expanded 
  distally 
  ; 
  club 
  of 
  three 
  

   segments. 
  Head 
  as 
  a 
  whole 
  very 
  long, 
  mandibles 
  powerful 
  ; 
  labial 
  and 
  maxillary 
  

   palpi 
  present,

  depressed, 
  with 
  very 
  

   long 
  pronotum.

  with 
  all 
  the 
  veins 
  developed, 
  the 
  radius 
  long. 
  Fore 
  legs 
  with 
  

   robust 
  femora 
  and 
  shortened, 
  heavily-armed 
  tibiae 
  ; 
  mid

  $. 
  Head 
  greatly 
  flattened, 
  much 
  longer 
  than 
  broad 
  (5:3); 
  from 
  the 
  insertion 
  

   of 
  the 
  antennae 
  to 
  the 
  vertex 
  runs 
  a 
  broad 
  depression, 
  at 
  the 
  bottom 
  of 
  which 
  are 
  

   two 
  narrow 
  diverging 
  furrows 
  for 
  the 
  reception 
  of 
  the 
  scapes 
  ; 
  scrobes 
  broadly 
  

   oval, 
  flattened 
  on

  different 
  planes 
  — 
  viz. 
  : 
  a 
  pair 
  on 
  the 
  

   vertex 
  (which 
  owing 
  to 
  the 
  shape 
  and 
  position 
  of 
  the 
  head 
  is 
  hardly 
  separable 
  from 
  

   the 
  occiput) 
  and 
  a 
  single 
  median 
  one 
  on 
  the 
  frons 
  above 
  the 
  scapes. 
  Vertex 
  

   exceedingly 
  narrow, 
  raised 
  in 
  a 
  median 
  rounded 
  prominence, 
  bearing 
  on 
  each 
  side 
  

   a 
  short, 
  stiff 
  bristle 
  ; 
  3 
  bristles 
  (of 
  which 
  the 
  median 
  is 
  the 
  longest) 
  at 
  each 
  corner
