  hind 
  tibiae 
  short, 
  compressed,

  having 
  near 
  

   the 
  knee 
  a

  the 
  apical 
  spur 
  is 
  situated

  the 
  base 
  

   of 
  the 
  hooked 
  inner 
  process

  the

  Male 
  : 
  Allied 
  to 
  the 
  preceding 
  species, 
  and 
  having 
  likewise 
  the 
  

   clypeus 
  sharply 
  tri-dentate 
  at 
  tip 
  ; 
  the 
  shape, 
  sculpture, 
  and 
  colour 
  

   of 
  the 
  prothorax 
  are 
  similar, 
  but 
  the 
  basal 
  transverse 
  impressions 
  

   are 
  a 
  little 
  deeper 
  ; 
  the 
  scutellum 
  is 
  non-scaly 
  ; 
  the 
  elytra 
  are 
  more 
  

   attenuate 
  laterally 
  towards 
  the 
  apex, 
  and 
  they 
  have 
  a 
  broad 
  juxta- 
  

   sutural 
  band 
  of 
  yellow 
  scales 
  reaching 
  from 
  the 
  base 
  to 
  the 
  apex 
  

   where 
  it 
  unites 
  with 
  a 
  marginal 
  one 
  of 
  nearly 
  the 
  same 
  width 
  ; 
  the 
  

   propygidium 
  and 
  pygidium 
  are 
  glabrous 
  ; 
  the 
  hind 
  femora 
  are 
  

   very 
  large, 
  sprinkled 
  with 
  numerous 
  scar-like 
  punctures, 
  and 
  are 
  

   shaped 
  as 
  in 
  H. 
  podagricus, 
  but 
  the 
  hind 
  tibiae 
  are 
  a 
  little 
  longer, 
  less 
  

   curved, 
  less 
  dilated 
  inwardly 
  at 
  apex, 
  with 
  the 
  apical 
  process 
  longer
