  on 
  the 
  

  

  sides, 
  without 
  trace 
  of 
  sinuation 
  before 
  hind 
  angles, 
  which, 
  like 
  the 
  

   front 
  angles, 
  are 
  rounded; 
  sides 
  finely 
  bordered, 
  with 
  a 
  seta 
  near 
  

   base; 
  surface 
  moderately 
  convex, 
  declivous 
  towards 
  front 
  angles, 
  

   fairly 
  strongly 
  but 
  not 
  closely 
  punctate 
  on 
  disk, 
  more 
  closely 
  at 
  sides 
  

   of 
  base, 
  an 
  irregular 
  row 
  of 
  punctures 
  on 
  each 
  side 
  of 
  median 
  line, 
  

   which 
  is 
  very 
  fine 
  and 
  does 
  not 
  reach 
  the 
  margins, 
  faintly 
  pubescent 
  

   near 
  hind 
  angles 
  ; 
  transverse 
  impressions 
  very 
  slight, 
  a 
  short 
  longi- 
  

   tudinal 
  furrow 
  on 
  each 
  side 
  of 
  base, 
  and 
  rather 
  distant 
  from 
  basal 
  

   margin. 
  

  

  Elytra 
  not 
  very 
  convex, 
  width 
  compared 
  with 
  prothorax 
  as 
  5 
  to 
  3, 
  

   margin 
  rounded 
  at 
  shoulder, 
  slightly 
  sinuate 
  before 
  apex, 
  striae 
  fairly 
  

   deep, 
  punctured, 
  intervals 
  rather 
  flat, 
  very 
  closely 
  and 
  finely 
  

   pimctate, 
  the 
  whole 
  surface 
  covered 
  with 
  a 
  dense 
  short 
  greyish 
  

   pubescence 
  ; 
  apical 
  spot 
  covering 
  apex 
  and 
  loinning 
  back 
  narrowly 
  

   to 
  the 
  marginal 
  sinuation, 
  whence 
  (leaving 
  the 
  margin) 
  it 
  extends 
  

   backwards 
  on 
  intervals 
  6, 
  7, 
  and 
  8, 
  and 
  in 
  front 
  sends 
  an 
  arm 
  inwards 
  

   to 
  stria 
  3. 
  

  

  Underside 
  smooth, 
  shining, 
  prostemal 
  process 
  faintly 
  bordered 
  

   at 
  apex, 
  a 
  few 
  punctures 
  on 
  middle 
  of 
  prosternum, 
  metastemum 
  with 
  

   a 
  few 
  coarse 
  punctures 
  at 
  sides, 
  metepistema 
  nearly 
  smooth, 
  half 
  as 
  

   long 
  again 
  as 
  wide, 
  with 
  a 
  furrow 
  along 
  outer 
  margin. 
  Front 
  

   femora 
  ((J) 
  without 
  tooth. 
  

  

  The 
  species 
  is 
  evidently 
  extremely 
  close 
  to 
  C. 
  bihamatus 
  

   Chaud., 
  but 
  is 
  a 
  little 
  smaller 
  than 
  specimens 
  in 
  my 
  collec- 
  

   tion 
  which 
  I 
  identify 
  with 
  Chaudoir's 
  species 
  ; 
  the 
  hind 
  

   angles 
  of 
  prothorax 
  more 
  evident, 
  surface 
  rather 
  more 
  

   closely 
  pmictured, 
  elytra 
  darker, 
  apical 
  spot 
  smaller. 
  

  

  In 
  addition 
  to 
  the 
  type 
  there 
  are 
  specimens 
  in 
  the 
  British 
  

   Musuem 
  Collection 
  from 
  Borneo, 
  labelled 
  " 
  Sarawak," 
  

   " 
  Sanga-Sanga," 
  and 
  " 
  Kuching." 
  In 
  these, 
  the 
  pro- 
  

   thorax 
  is 
  more 
  contracted 
  behind 
  than 
  in 
  the 
  type, 
  and 
  

   the 
  elytral 
  spot 
  is 
  rather 
  smaller 
  — 
  indeed, 
  in 
  one 
  example 
  

   it 
  is 
  reduced 
  to 
  only 
  half 
  the 
  normal 
  length, 
  and 
  does 
  not 
  

   nearly 
  reach 
  the 
  apex. 
  As 
  the 
  species 
  is 
  apparently 
  a 
  

   variable 
  one,, 
  it 
  may 
  prove 
  that 
  it 
  is 
  really 
  identical 
  with 
  

   C. 
  bihamatus, 
  but 
  this 
  can 
  only 
  be 
  settled 
  when 
  the 
  type 
  of 
  

   the 
  latter 
  is 
  available 
  for 
  comparison. 
  As 
  Chaudoir's 
  de- 
  

   scription 
  is 
  a 
  short 
  one, 
  I 
  shall 
  in 
  any 
  case 
  have 
  done 
  no 
  

   harm 
  in 
  giving 
  a 
  fuller 
  one. 
  

  

  It 
  may 
  be 
  worth 
  while 
  pointing 
  out 
  here 
  that 
  when 
  

   C. 
  bihamatus 
  was 
  described 
  (Bull. 
  Mosc. 
  1856, 
  iii, 
  210) 
  

   Chaudoir 
  said 
  he 
  had 
  received 
  two 
  examples 
  taken 
  by 
  Capt. 
  

   Boys 
  in 
  N. 
  India, 
  and 
  another 
  from 
  Tranquebar 
  ;
