  Very 
  closely 
  allied 
  to 
  A. 
  exasperans 
  and 
  A. 
  fraudator, 
  especially 
  

   to 
  the 
  latter, 
  the 
  colour 
  is 
  the 
  same, 
  but 
  the 
  clypeus 
  is 
  nearly 
  straight 
  

   at 
  the 
  apex 
  in 
  the 
  $ 
  with 
  the 
  angles 
  rounded, 
  the 
  punctures 
  on 
  the 
  

   prothorax 
  are 
  more 
  shallow, 
  the 
  costules 
  on 
  the 
  elytra 
  are 
  a 
  little 
  less 
  

   noticeable 
  ; 
  the 
  colour 
  of 
  the 
  body 
  is 
  pale 
  testaceous, 
  with 
  the 
  head 
  

   somewhat 
  infuscate 
  in 
  the 
  posterior 
  part, 
  the 
  suture 
  is 
  hardly 
  darker 
  

   than 
  the 
  background 
  of 
  the 
  elytra, 
  and 
  the 
  tarsi 
  are 
  brownish 
  ; 
  in 
  shape 
  

   the 
  clypeus 
  resembles 
  that 
  of 
  A. 
  exasperans 
  and 
  A. 
  impurus, 
  but 
  it 
  

   is 
  transversely 
  straighter 
  at 
  the 
  apex, 
  and 
  the 
  shape 
  of 
  the 
  genital 
  

   armature 
  of 
  the 
  male 
  differs 
  from 
  both, 
  being 
  broader, 
  shorter, 
  more 
  

   ovately 
  open 
  on 
  the 
  upper 
  side, 
  abruptly 
  acuminate 
  near 
  the 
  apex, 
  

   .and 
  narrowly 
  cleft 
  there.

  Testaceous 
  brown, 
  very 
  faintly 
  metallic, 
  head 
  fuscous, 
  median 
  

   part 
  of 
  prothorax 
  sometimes 
  slightly 
  infuscate 
  in 
  the 
  discoidal 
  

   part 
  ; 
  clypeus 
  semicircular, 
  scabroso-punctate, 
  separated 
  from 
  the 
  

   head 
  by 
  a 
  very 
  distinct 
  carina, 
  head 
  moderately 
  closely 
  punctate, 
  

   and 
  with 
  a 
  somewhat 
  more 
  distinct 
  metallic 
  sheen, 
  each 
  puncture 
  

   bears 
  a 
  small 
  whitish 
  appressed 
  hair 
  ; 
  prothorax 
  covered 
  with 
  closely 
  

   •set 
  but 
  not 
  contiguous, 
  and 
  somewhat 
  irregular, 
  small, 
  deep 
  punctures 
  

   emitting 
  each 
  a 
  very 
  fine 
  whitish 
  appressed 
  hair 
  ; 
  scutellum 
  closely 
  

   punctured 
  ; 
  elytra 
  very 
  plainly 
  costate, 
  the 
  costse 
  smooth 
  and 
  im- 
  

   punctate 
  and 
  having 
  each 
  a 
  series 
  of 
  very 
  distant, 
  short 
  white 
  

   bristles, 
  the 
  intervals 
  are 
  filled 
  with 
  irregular, 
  deep, 
  nearly 
  con- 
  

   tiguous 
  punctures 
  separated 
  by 
  raised, 
  sinuose 
  walls, 
  the 
  suture 
  

   is 
  raised, 
  they 
  are 
  not 
  strongly 
  callose 
  at 
  the 
  apex, 
  and 
  each 
  

   puncture 
  bears 
  a 
  very 
  minute 
  greyish-white 
  hair 
  ; 
  the 
  pygidium, 
  

   under 
  side, 
  and 
  legs 
  are 
  somewhat 
  thinly 
  clothed 
  with 
  greyish 
  

   appressed 
  hairs 
  ; 
  all 
  the 
  tarsi 
  are 
  reddish 
  brown 
  ; 
  the 
  sheath 
  of 
  the 
  

   genital 
  armature 
  is 
  entirely 
  open 
  on 
  the 
  upper 
  side, 
  not 
  very 
  

   declivous, 
  sinuate, 
  deeply 
  emarginate 
  laterally, 
  at 
  a 
  short 
  distance 
  

   from 
  the 
  apex, 
  very 
  slightly 
  incised 
  at 
  the 
  middle, 
  the 
  inner 
  angle 
  

  

  genital 
  armature 
  is 
  different 
  from 
  that 
  of 
  both 
  A. 
  capicola 
  and 
  A. 
  punctipennis.

  Shape, 
  size, 
  and 
  sculpture 
  of 
  A. 
  impurus, 
  but 
  the 
  colour 
  is 
  a 
  little 
  darker, 
  and 
  

   the 
  coating 
  of 
  squamulose 
  hairs 
  is 
  a 
  little 
  denser, 
  the 
  clypeus 
  of 
  the 
  male 
  is 
  

   plainly 
  truncate 
  instead 
  of 
  being 
  arcuate, 
  as 
  in 
  A. 
  impurus, 
  and 
  is 
  therefore 
  more 
  

   like 
  that 
  of 
  A. 
  exasperans, 
  but 
  it 
  is 
  even 
  straighter 
  than 
  in 
  this 
  last-named 
  species, 
  

   ;and 
  the 
  genital 
  armature 
  is 
  very 
  different 
  in 
  shape 
  from 
  that 
  of 
  any 
  of 
  the 
  other 
  

   .South 
  African 
  species.
