  I 
  have 
  not 
  seen 
  the 
  female 
  of 
  this 
  interesting

  Mentum 
  long, 
  ampliated 
  laterally 
  from 
  the 
  base 
  which 
  is 
  not 
  broad, 
  

   suddenly 
  narrowed 
  at 
  some 
  distance 
  from 
  the 
  apex, 
  and 
  straight 
  

   from 
  there, 
  lobes 
  of 
  ligula 
  broad, 
  very 
  divaricating, 
  and 
  fringed 
  

   inwardly 
  with 
  hairs, 
  labial 
  palpi 
  somewhat 
  short, 
  apical 
  joint 
  quite 
  

   cylindrical 
  and 
  longer

  the 
  preceding 
  one 
  which 
  is 
  swollen 
  ; 
  

   maxillae 
  wholly 
  or 
  partly 
  horny,

  case 
  the 
  upper 
  lobe 
  is 
  short, 
  with 
  only 
  one 
  basal 
  

   tooth 
  when 
  the 
  lobe 
  is 
  longer, 
  and 
  fasciculate 
  with 
  long 
  hairs, 
  even 
  

   in 
  one 
  species 
  (E.

  there 
  is 
  no 
  tooth 
  at 
  all,
