  denuded 
  conspicuous

  the

  at

  Male 
  : 
  Chocolate-brown, 
  a 
  little 
  darker 
  on 
  the 
  prothorax 
  than 
  on 
  

   the 
  rest 
  of 
  the 
  body, 
  sparingly 
  sprinkled 
  above 
  and 
  beneath 
  with 
  

   slightly 
  elongated 
  white 
  scales 
  ; 
  head 
  and 
  prothorax 
  similar 
  in 
  shape 
  

   to 
  that 
  of 
  M. 
  formosus, 
  but 
  the 
  latter 
  is 
  not 
  so 
  deeply 
  or 
  closely 
  

   scabroso-punctate 
  ; 
  the 
  elytra 
  are 
  similar, 
  but 
  the 
  shape 
  of 
  the 
  hind 
  

   tibiae 
  is 
  very 
  different 
  ; 
  the 
  spine 
  of 
  the 
  trochanters 
  is 
  small, 
  and 
  the 
  

   apical 
  spine 
  of 
  the 
  femora 
  beneath, 
  under 
  the 
  knee, 
  is 
  conspicuous 
  ; 
  

   the 
  tibiae 
  are 
  deeply 
  grooved 
  beneath, 
  the 
  outer 
  edge 
  is 
  very 
  sharply 
  

   angular 
  near 
  the 
  knee 
  and 
  ends 
  in 
  a 
  sharp, 
  curved 
  mucro 
  at 
  apex, 
  

   and 
  the 
  inner 
  edge 
  is 
  simple, 
  while 
  the 
  upper 
  carina 
  is 
  conspicuously 
  

   keeled 
  ; 
  hind 
  claws 
  single, 
  simple.

  Hab. 
  Cape 
  Colony 
  (exact 
  locality 
  unknown). 
  

  

  I 
  have 
  seen 
  three 
  examples 
  only, 
  collected 
  by 
  Drege, 
  the 
  locality 
  

   of 
  which 
  is 
  not 
  recorded, 
  but 
  I 
  think 
  they 
  are 
  from 
  Namaqualand.

  with 
  the 
  two 
  denuded, 
  discoidal 
  bands 
  smooth, 
  

   anterior 
  and 
  lateral 
  margins 
  fringed 
  with 
  very 
  long, 
  dense 
  yellow 
  

   bristles 
  ; 
  scutellum 
  sub-ogival 
  ; 
  elytra 
  non-costulate, 
  very 
  vaguely 
  

   and 
  sparingly 
  punctate, 
  attenuate 
  laterally 
  towards 
  the 
  apex, 
  and 
  

   glabrous 
  ; 
  posterior 
  femora 
  very 
  robust, 
  armed 
  with 
  a 
  conspicuous 
  

   tooth 
  beneath, 
  under 
  the 
  knee, 
  and 
  having 
  the 
  trochanters 
  very 
  long
