   Buccal 
  organs 
  of 
  Lepitrix, 
  the 
  lobes 
  of 
  the 
  ligula 
  are 
  also 
  long, 
  

   but 
  broader 
  and 
  spatulate, 
  the 
  anterior 
  tibiae 
  have 
  no 
  trace 
  of 
  a 
  third 
  

   basal 
  tooth, 
  but 
  the 
  shape 
  of 
  the> 
  clypeus 
  is 
  very 
  different 
  being 
  

   declivous, 
  rounded 
  in 
  front, 
  and 
  with 
  the 
  margins 
  highly 
  raised 
  all 
  

   round 
  ; 
  the 
  hind 
  tarsi 
  are 
  long, 
  and 
  the 
  joints 
  are 
  clothed 
  with 
  very 
  

   long 
  feathery 
  hairs 
  in 
  one 
  species, 
  but 
  not 
  in 
  the 
  other, 
  the 
  whole 
  

   propygidium 
  is 
  left 
  uncovered 
  by 
  the 
  elytra 
  ; 
  the 
  anterior 
  tibiae 
  are 
  

   bi-dentate, 
  and 
  have 
  an 
  inner 
  spur.
