  are 
  as 
  numerous 
  on 
  the 
  prothorax 
  as 
  on 
  the 
  elytra 
  or 
  the 
  pygidial 
  

   part 
  ; 
  the 
  clypeus 
  is 
  quite 
  straight, 
  and 
  on 
  the 
  clypeus 
  and 
  the 
  

   frontal 
  part 
  there 
  are 
  three 
  transverse 
  rows 
  of 
  stiff, 
  short 
  bristles 
  ; 
  the 
  

   prothorax 
  has 
  no 
  median 
  impression, 
  and 
  the 
  elytra 
  are 
  normally 
  

   attenuate 
  laterally 
  and 
  not 
  costate 
  ; 
  the 
  pygidium 
  is 
  strongly 
  directed 
  

   forward 
  and 
  covered 
  with 
  concolorous 
  hair-like 
  scales, 
  the 
  hind 
  

   femora 
  are 
  robust 
  and 
  simple, 
  the 
  hind 
  tibiae 
  are 
  also 
  simple, 
  

   somewhat 
  gradually 
  dilated 
  towards 
  the 
  apex, 
  compressed 
  inwardly 
  

   and 
  not 
  mucronate, 
  the 
  apical 
  spur 
  is 
  distinct 
  and 
  the 
  single 
  hind 
  

   claw 
  is 
  simple. 
  

  

  Female 
  : 
  Like 
  the 
  male, 
  but 
  the 
  prothorax 
  is 
  more 
  pubescent, 
  and 
  

   the. 
  scales 
  on 
  the 
  elytra 
  and 
  pygidial 
  part 
  are 
  more 
  like 
  sub-squamose 
  

   hairs 
  and 
  are 
  not 
  so 
  dense.

  This 
  species 
  can 
  easily 
  be 
  recognised 
  by 
  the 
  straight 
  apical 
  part 
  of 
  

   the 
  clypeus 
  as 
  well 
  as 
  by 
  the 
  thick 
  and 
  very 
  elongate 
  scales 
  covering 
  

   the 
  body.
