  long 
  in 
  the 
  centre

  wide, 
  very 
  parabolic, 
  very 
  scabrose, 
  head 
  more 
  

   closely 
  scabroso-punctate 
  than 
  the 
  clypeus, 
  both 
  with 
  a 
  very 
  short 
  

   appressed 
  pubescence 
  partly 
  obliterated 
  in 
  my 
  example 
  ; 
  prothorax 
  

   not 
  much 
  attenuated 
  laterally 
  in 
  front, 
  covered 
  with 
  closely 
  set 
  

   punctures 
  separated 
  from 
  each 
  other 
  by 
  a 
  space 
  corresponding 
  to 
  

   half 
  their 
  diameter, 
  and 
  having 
  in 
  the 
  median 
  part 
  of 
  the 
  disk 
  a 
  

   transverse 
  lozenge-shaped 
  shallow 
  impression 
  ; 
  scutellum 
  punctu- 
  

   late 
  ; 
  elytra 
  not 
  quite 
  as 
  broad 
  at 
  the 
  base 
  as 
  the 
  base 
  of 
  the 
  

   prothorax, 
  but 
  much 
  more 
  so 
  towards 
  the 
  apical 
  part, 
  plainly 
  

   costulate, 
  the 
  costae 
  are 
  impunctate 
  but 
  the 
  intervals 
  are 
  filled 
  

   with 
  closely 
  set 
  but 
  not 
  contiguous, 
  moderately 
  regular 
  punc- 
  

   tures 
  ; 
  the 
  four 
  series 
  of 
  bristles 
  cannot 
  be 
  detected 
  in 
  my 
  example 
  

   which 
  is 
  a 
  female, 
  the 
  carina 
  of 
  the 
  epipleural 
  fold 
  is 
  deeply 
  punc- 
  

   tured 
  at 
  remote 
  intervals 
  ; 
  tho 
  larger 
  anterior 
  claw 
  is 
  deeply 
  cleft 
  at 
  

   the 
  apex, 
  and 
  the 
  inner 
  claw 
  of 
  the

  is 
  very 
  small,

   distinct.

  Adoretus 
  dissidens,

   Plate 
  XLL, 
  fig. 
  18. 
  

  

  Testaceous, 
  but 
  somewhat 
  infuscate 
  on 
  the 
  upper 
  side, 
  and 
  with 
  a 
  

   slight 
  metallic 
  sheen 
  more 
  noticeable 
  on 
  the 
  head 
  and 
  prothorax 
  ; 
  

   head 
  and 
  clypeus 
  granuloso-punctate, 
  the 
  former 
  is 
  nearly 
  straight 
  

   laterally 
  at 
  the 
  base 
  and 
  parabolic 
  in 
  front 
  ; 
  the 
  punctures 
  of 
  the 
  

   prothorax 
  are 
  small, 
  but 
  very 
  closely 
  set, 
  especially 
  on 
  the 
  sides, 
  and 
  

   there 
  is 
  a 
  slight 
  median 
  longitudinal 
  impression, 
  the 
  small, 
  white 
  

   appressed 
  hairs 
  clothing 
  the 
  head 
  and 
  prothorax 
  are 
  only 
  moderately 
  

   dense 
  ; 
  the 
  elytra 
  are 
  distinctly 
  costate, 
  the 
  costae 
  are 
  lighter 
  than 
  

   the 
  rest 
  of 
  the 
  background, 
  but 
  are 
  interrupted 
  at 
  regular 
  intervals 
  

   by 
  a 
  fuscous 
  patch 
  which 
  imparts 
  to 
  them 
  a 
  tesselated 
  appearance, 
  

   the 
  intervals 
  are 
  filled 
  with 
  somewhat 
  irregular, 
  closely 
  set, 
  mode- 
  

   rately 
  deep 
  punctures, 
  the 
  greyish 
  appressed 
  pubescence 
  is 
  some- 
  

   what 
  dense 
  ; 
  the 
  hind 
  legs 
  and 
  all 
  the 
  tarsi 
  are 
  ferruginous 
  ; 
  the 
  

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

   upper 
  side, 
  parallel, 
  straight 
  transversely 
  at 
  the 
  tip 
  but 
  slightly 
  

   attenuate 
  obliquely 
  laterally.

  Adoretus 
  sebakuensis, 
  n. 
  spec, 
  pi. 
  xliii., 
  fig. 
  29. 
  

   Pale 
  testaceous, 
  the 
  head 
  is 
  a 
  little 
  infuscate, 
  the 
  whole 
  body, 
  except 
  the 
  legs, 
  is 
  

   covered 
  with 
  a 
  coating 
  of 
  white 
  squamose 
  hairs 
  hiding 
  the 
  background 
  ; 
  the 
  hind 
  

   tarsi 
  are 
  fuscous 
  ; 
  the 
  clypeus 
  of 
  the 
  male 
  is 
  much 
  more 
  parallel 
  than 
  in 
  any 
  of 
  the 
  

   other 
  South 
  African 
  species 
  and 
  quite 
  transverse 
  in 
  front, 
  but 
  in 
  the 
  female 
  it 
  is 
  

   plainly 
  arcuate 
  ; 
  the 
  prothorax 
  and 
  elytra 
  are 
  very 
  closely 
  punctured, 
  but 
  the 
  

   punctures 
  are 
  hidden 
  by 
  the 
  vestiture, 
  the 
  elytra 
  are 
  very 
  obsoletely 
  tri-costate 
  on 
  

   each 
  side, 
  and 
  the 
  apical 
  part 
  of 
  the 
  pygidium 
  has 
  no 
  squamose 
  hairs. 
  In 
  general 
  

   appearance 
  it 
  is 
  not 
  unlike 
  A. 
  capicola, 
  but 
  is 
  easily 
  recognised 
  by 
  the 
  shape 
  of 
  the 
  

   head, 
  the 
  absence 
  of 
  spinose 
  trochanters 
  in 
  the 
  male, 
  the 
  less 
  distinctly 
  costulate 
  

   elytra, 
  and 
  the 
  denser 
  and 
  whiter 
  coating 
  of 
  squamose 
  hairs; 
  the 
  shape 
  of 
  the
