  Fuscous

  upper

  with 
  the 
  clypeus, 
  the 
  sides 
  of 
  

   the 
  prothorax 
  and 
  the 
  elytra 
  lighter 
  brown, 
  under 
  side 
  and 
  legs 
  

   testaceous 
  red, 
  hind 
  legs 
  somewhat 
  infuscate 
  ; 
  clypeus 
  straight 
  

   laterally 
  at 
  the 
  base, 
  rounded 
  thence 
  but 
  distinctly 
  emarginate 
  

   in 
  the 
  centre 
  in 
  the 
  male, 
  but 
  not 
  in 
  the 
  female, 
  the 
  suture 
  with 
  

   the 
  head 
  is 
  slender 
  but 
  distinct, 
  and 
  both 
  the 
  head 
  and 
  clypeus 
  

   are 
  scabrose 
  and 
  covered 
  with 
  dense 
  greyish 
  hairs 
  ; 
  prothorax 
  also 
  

   clothed 
  with 
  dense 
  appressed 
  hairs, 
  it 
  is 
  very 
  closely 
  punctured, 
  and 
  

   has 
  a 
  metallic 
  sheen; 
  elytra 
  plainly 
  tri-costulate 
  on 
  each 
  side, 
  deeply 
  

   punctured 
  and 
  clothed 
  with 
  fine, 
  short, 
  very 
  closely 
  set 
  appressed 
  

   hairs, 
  the 
  three 
  costge 
  of 
  the 
  elytra 
  are 
  regularly 
  hairy 
  but 
  have 
  

   a 
  tesselate 
  appearance 
  owing 
  to 
  the 
  hairs 
  being 
  interrupted 
  at 
  

   regular 
  intervals 
  by 
  denuded, 
  transverse 
  patches 
  ; 
  the 
  sheath 
  of 
  

   the 
  genital 
  armature 
  of 
  the 
  male 
  is 
  entirely 
  open 
  on 
  the 
  upper 
  

   side, 
  slightly 
  sinuate 
  laterally 
  but 
  sub-parallel 
  for 
  the 
  greater 
  part 
  

   of 
  the 
  length 
  and 
  obliquely 
  truncate 
  on 
  each 
  side 
  towards 
  the 
  apex 
  

   which 
  is 
  not 
  deeply 
  emarginate 
  and 
  is 
  not 
  cleft. 
  

  

  This 
  species 
  is 
  very 
  closely 
  allied 
  to 
  A. 
  obscurus 
  from 
  Senegambia. 
  

   The 
  shape 
  of 
  the 
  head 
  and 
  vestiture 
  are 
  identical, 
  but 
  the 
  sheath 
  of 
  

   the 
  genital 
  armature 
  is 
  not 
  so 
  obliquely 
  truncate 
  laterally 
  and 
  is 
  

   broader 
  at 
  the 
  apex.

  Pale 
  testaceous, 
  with 
  the 
  head 
  and 
  the 
  hind 
  tibiae 
  fuscous 
  black, 
  

  

  clothed 
  with 
  greyish

  hairs 
  ; 
  closely 
  allied 
  

  

  to

  and

  A. 
  flaveolus,

  differs 
  from 
  the 
  former 
  in 
  

  

  having 
  the

  Adoretus

  Pale 
  testaceous, 
  slightly 
  metallic, 
  and 
  covered 
  on 
  the 
  upper 
  and 
  under 
  sides 
  and 
  

   also 
  on 
  the 
  legs 
  with 
  somewhat 
  long 
  and 
  very 
  dense 
  squamulose, 
  appressed, 
  

   fiavescent 
  hairs, 
  so 
  closely 
  set 
  on 
  the 
  scutellum 
  as 
  to 
  hide 
  the 
  whole 
  surface 
  ; 
  the 
  

   clypeus 
  is 
  rounded 
  laterally 
  and 
  truncate 
  in 
  the 
  anterior 
  part 
  in 
  the 
  male, 
  sub- 
  

   acuminate 
  there 
  in 
  the 
  female, 
  in 
  which 
  the 
  median 
  lateral 
  part 
  of 
  the 
  prothorax 
  is 
  

   also 
  slightly 
  more 
  ampliate 
  than 
  in 
  the 
  male 
  ; 
  the 
  elytra 
  are 
  plainly 
  costate 
  ; 
  the 
  

   joints 
  of 
  the 
  tarsi 
  are 
  very 
  short, 
  but 
  the 
  apical 
  one 
  is 
  long 
  and 
  very 
  robust 
  in 
  the 
  

   male, 
  and 
  in 
  both 
  sexes 
  the 
  apical 
  outer 
  tooth 
  of 
  the 
  anterior 
  tibiae 
  is 
  a 
  little 
  

   shorter 
  than 
  in 
  the 
  intermediate. 
  The 
  genital 
  armature 
  differs 
  much 
  from 
  that 
  

   of 
  the 
  other 
  South 
  African 
  species.
