  the 
  upper 
  side 
  ; 
  shape 
  and 
  sculpture 
  of 
  the 
  head 
  and 
  clypeus 
  similar 
  

   to 
  that 
  of 
  C. 
  pilosulus 
  ; 
  the 
  prothorax 
  is 
  covered 
  with 
  nearly 
  con- 
  

   fluent 
  punctures 
  separated 
  by 
  irregular, 
  not 
  scabrose 
  walls, 
  the 
  

   punctures 
  do 
  not 
  bear 
  each 
  a 
  short, 
  appressed 
  hair, 
  and 
  are 
  equi- 
  

   distant 
  and 
  somewhat 
  remote 
  ; 
  the 
  elytra, 
  including 
  the 
  greatest 
  

   part 
  of 
  the 
  suture, 
  are 
  pluri-costulate 
  and 
  covered 
  with 
  nearly 
  

   contiguous 
  punctures 
  the 
  irregular 
  walls 
  of 
  which 
  make 
  the 
  

   surface 
  appear 
  shagreened, 
  and 
  each 
  puncture 
  bears 
  a 
  minute 
  

   appressed 
  sub-flavescent 
  hair 
  ; 
  the 
  pygidium 
  is 
  briefly 
  pubescent 
  all 
  

   round, 
  but 
  has 
  on 
  the 
  surface 
  hairs 
  similar 
  to 
  those 
  on 
  the 
  elytra, 
  

   and 
  those 
  on 
  the 
  under 
  side, 
  especially 
  on 
  the 
  abdomen, 
  are 
  alike 
  ; 
  the 
  

   claws 
  of 
  all 
  the 
  legs 
  are 
  double 
  and 
  unequal, 
  but 
  the 
  smaller 
  one 
  is 
  

   nearly 
  as 
  long 
  as 
  the 
  stronger, 
  and 
  all 
  are 
  slightly 
  bifid 
  at 
  the 
  tip.

  Male 
  : 
  Head 
  black 
  with 
  the 
  clypeus 
  slightly 
  brown, 
  prothorax 
  and 
  

   elytra 
  chestnut-brown, 
  but 
  with 
  the 
  median 
  anterior 
  part 
  of 
  the 
  

   former 
  a 
  little 
  infuscate 
  ; 
  both 
  the 
  head 
  and 
  clypeus 
  are 
  equally 
  

   shagreened, 
  the 
  clypeus 
  is 
  short 
  but 
  broad, 
  straight 
  at 
  the 
  apex 
  and 
  

   with 
  the 
  outer 
  angles 
  slightly 
  rounded, 
  and 
  is 
  divided 
  from 
  the 
  head 
  

   by 
  a 
  conspicuous 
  transverse 
  carinule 
  ; 
  prothorax 
  very 
  finely 
  punc- 
  

   tured, 
  the 
  punctures 
  are 
  very 
  dense, 
  and 
  among 
  them 
  are 
  some 
  large 
  

   ones 
  bearing 
  each 
  a 
  very 
  short, 
  appressed 
  greyish 
  hair 
  ; 
  prothorax 
  

   with 
  hardly 
  any 
  puncture 
  ; 
  elytra 
  elongate, 
  only 
  slightly 
  broader 
  

   than 
  the 
  prothorax 
  at 
  the 
  base 
  but 
  broader 
  at 
  the 
  apex, 
  plainly 
  

   bi-costate 
  on 
  each 
  side, 
  but 
  having 
  also 
  a 
  less 
  well-defined 
  third 
  

   discoidal 
  costule, 
  the 
  suture 
  is 
  raised, 
  and 
  it 
  is 
  covered 
  by 
  very 
  

   closely 
  set 
  punctures 
  bearing 
  each 
  a 
  minute 
  greyish 
  flavescent 
  

   appressed 
  hair 
  ; 
  pygidium, 
  abdomen, 
  and 
  hairs 
  with 
  similar 
  hairs 
  

   which 
  are 
  not, 
  however, 
  so 
  closely 
  set 
  ; 
  legs 
  testaceous. 
  

  

  Female 
  : 
  The 
  female 
  is 
  very 
  different 
  from 
  the 
  male 
  ; 
  it 
  is 
  reddish 
  

   brown 
  all 
  over, 
  the 
  prothorax 
  has 
  much 
  more 
  numerous 
  cicatricose 
  

   punctures 
  and 
  the 
  elytra 
  are 
  covered 
  with 
  broad 
  very 
  closely 
  set 
  

   punctures 
  having 
  a 
  smaller 
  one 
  in 
  the 
  centre, 
  these 
  punctures 
  

   are 
  more 
  cicatricose 
  in 
  the 
  anterior 
  than 
  in 
  the 
  posterior 
  part, 
  the 
  

   appressed 
  hairs 
  are 
  considerably 
  less 
  dense 
  and 
  are 
  finer.

  This

  in 
  general 
  appearance 
  some 
  species 
  

   of 
  Congella.
