  The 
  type 
  of 
  Wiedeman's 
  

   description. 
  One 
  of 
  the 
  largest 
  species, 
  and 
  on 
  that 
  account 
  less 
  like 
  

   the 
  series 
  of 
  the 
  preceding 
  species 
  (pachyglutus, 
  hybridus, 
  auran- 
  

   tiacus, 
  sobrinus, 
  bimaculatus 
  , 
  &c). 
  Black, 
  antennae, 
  palpi, 
  legs, 
  and 
  

   elytra 
  reddish 
  brown 
  ; 
  head 
  and 
  anterior 
  part 
  of 
  prothorax 
  thickly 
  

   punctulate 
  ; 
  apical 
  margin 
  of 
  clypeus 
  quadri-dentate, 
  the 
  two 
  median 
  

   teeth 
  smaller 
  than 
  the 
  lateral 
  ones, 
  the 
  punctures 
  bear 
  each 
  a 
  short 
  

   greyish-yellow 
  hair 
  recurved 
  at 
  tip, 
  these 
  hairs 
  are 
  not 
  so 
  dense 
  in 
  the 
  

   posterior 
  part, 
  and 
  turn 
  to 
  scales 
  ; 
  scutellum, 
  elytra 
  and 
  pygidial 
  part 
  

   thickly 
  clothed 
  with 
  scales 
  of 
  the 
  same 
  colour 
  ; 
  the 
  pygidial 
  part 
  is 
  

   also 
  hairy 
  as 
  well 
  as 
  the 
  pectus 
  and 
  the 
  legs 
  are 
  sparingly 
  scaly 
  ; 
  the 
  

   latter 
  are 
  strong 
  and 
  robust, 
  the 
  hind 
  thighs 
  of 
  the 
  male 
  have 
  the 
  

   trochanter

  tooth 
  

   close 
  to 
  the

  the 
  hind 
  femora 
  have 
  an 
  inner 
  tooth 
  near 
  the 
  knee 
  

   but 
  more 
  developed 
  than 
  the 
  one 
  on

  it,

  another 
  

   and

  one 
  above

  mucronate 
  end,
