  outer 
  margin 
  is 
  a 
  series 
  of 
  setigerous 
  punctures 
  often 
  asymmetrical 
  

   and 
  varying 
  from 
  7 
  to 
  8 
  ; 
  scutellum 
  ogival, 
  slightly 
  transversely 
  

   impressed 
  at 
  the 
  base 
  and 
  a 
  little 
  broader 
  than 
  long 
  ; 
  elytra 
  very 
  

   little 
  wider 
  at 
  the 
  base 
  than 
  the 
  basal 
  part 
  of 
  the 
  prothorax, 
  slightly 
  

   bi- 
  sinuate 
  below 
  the 
  humeral 
  angle, 
  and 
  gradually 
  ampliated 
  laterally 
  

   from 
  one-third 
  to 
  about 
  three-fourths 
  of 
  the 
  length, 
  and 
  not 
  much 
  

   attenuate 
  thence 
  towards 
  the 
  rounded 
  posterior 
  part, 
  the 
  outer 
  and 
  

   posterior 
  margins 
  are 
  sharp, 
  they 
  are 
  moderately 
  convex, 
  but 
  more 
  

   so 
  in 
  the 
  posterior 
  part 
  where 
  there 
  is 
  a 
  median 
  supra-apical 
  callus, 
  

   near 
  the 
  humeral 
  angle 
  there 
  is 
  also 
  a 
  conspicuous 
  one 
  which 
  is 
  

   sometimes 
  prolonged 
  for 
  one-sixth 
  of 
  the 
  length 
  as 
  an 
  elongate 
  

   raised 
  surface, 
  they 
  have 
  more 
  or 
  less 
  deeply 
  punctured 
  striae, 
  

   geminate 
  in 
  the 
  dorsal 
  part 
  and 
  separated 
  by 
  smooth 
  or 
  punctured, 
  

   round 
  or 
  sharp 
  costae, 
  the 
  striae 
  of 
  the 
  median 
  dorsal 
  part 
  do 
  not 
  

   reach 
  quite 
  the 
  apex, 
  and 
  the 
  supra-lateral 
  ones 
  are 
  interrupted 
  on 
  

   the 
  humeral 
  callus, 
  between 
  the 
  second 
  and 
  third 
  dorsal 
  costae 
  the 
  

   space 
  is 
  somewhat 
  broadening 
  near 
  the 
  base 
  and 
  filled 
  with 
  numerous 
  

   punctures 
  resolving 
  themselves 
  into 
  one 
  or 
  two 
  regular 
  series 
  at 
  

   some 
  distance 
  from 
  the 
  base 
  ; 
  the 
  propygidium 
  is 
  partly 
  covered 
  by 
  

   the 
  elytra, 
  the 
  latter 
  is 
  declivous 
  or 
  abruptly 
  sloping 
  and 
  more 
  or 
  

   less 
  convex, 
  and 
  has 
  a 
  fringe 
  of 
  hairs 
  along 
  the 
  inferior 
  margin 
  ; 
  

   the 
  segment 
  of 
  the 
  abdomen, 
  except 
  the 
  sixth 
  and 
  seventh 
  in 
  the 
  

   male 
  and 
  the 
  sixth 
  in 
  the 
  female, 
  has 
  a 
  transverse 
  series 
  of 
  deep 
  

   setigerous 
  punctures 
  ; 
  metasternum 
  somewhat 
  broad, 
  usually 
  with 
  a 
  

   shallow 
  median 
  impressed 
  line 
  or 
  depression 
  ; 
  mesosternum 
  not 
  

   acuminate 
  between 
  the 
  intermediate 
  coxae 
  the 
  anterior 
  edges 
  of 
  

   which 
  as 
  well 
  as 
  of 
  the 
  posterior 
  ones 
  are 
  sharply 
  carinate 
  ; 
  hind 
  

   trochanters 
  with 
  a 
  lobate 
  process 
  ; 
  anterior 
  tibiae 
  bi- 
  or 
  tri-dentate 
  

   and 
  having 
  a 
  very 
  distinct 
  inner 
  spur 
  situated 
  at 
  some 
  distance 
  from 
  

   the 
  point 
  of 
  insertion 
  of 
  the 
  tarsi 
  the 
  joints 
  of 
  which 
  are 
  robust, 
  sub- 
  

   triangular, 
  spinose 
  beneath 
  and 
  provided 
  with 
  two 
  hinged 
  parallel 
  

   claws 
  the 
  outer 
  of 
  which 
  is 
  a 
  little 
  shorter 
  than 
  the 
  inner 
  ; 
  this 
  latter 
  

   is 
  either 
  simple 
  in 
  the 
  anterior 
  and 
  intermediate 
  tarsi, 
  simple 
  in 
  the 
  

   anterior 
  only, 
  or 
  cleft 
  transversely 
  in 
  the 
  male, 
  but 
  in 
  all 
  the 
  South 
  

   African 
  species 
  known 
  to 
  me, 
  except 
  one 
  (A. 
  nigrovestita), 
  the 
  female 
  

   has 
  the 
  claw 
  of 
  both 
  the 
  anterior 
  and 
  intermediate 
  tarsi 
  cleft 
  ; 
  the 
  in- 
  

   termediate 
  and 
  hind 
  tibiae 
  are 
  compressed 
  inwardly, 
  slightly 
  attenuate 
  

   at 
  apex 
  and 
  have 
  two 
  slight, 
  transverse 
  bristly 
  ridges 
  on 
  the 
  outer 
  

   part. 
  The 
  livery 
  of 
  the 
  South 
  African 
  species 
  is 
  of 
  two 
  sorts. 
  They 
  

   are 
  either 
  completely 
  more 
  or 
  less 
  pale 
  testaceous 
  : 
  the 
  elytra 
  are 
  

   either 
  entirely 
  or 
  partly 
  black 
  and 
  shiny, 
  but 
  without 
  a 
  metallic 
  

   sheen 
  : 
  or 
  the 
  upper 
  side, 
  and 
  sometimes 
  the 
  whole 
  body, 
  is 
  metallic 
  

   and 
  either 
  variegated 
  with 
  bronze-red, 
  brown 
  or 
  black, 
  or 
  also
