  I 
  mention 
  in 
  the 
  description 
  of 
  this 
  genus, 
  p. 
  307, 
  line 
  10, 
  that 
  the 
  

   joints 
  of 
  the 
  intermediate 
  and 
  posterior 
  tarsi 
  are 
  fused 
  and 
  vary 
  in 
  

   number 
  from 
  two 
  to 
  five. 
  It 
  is 
  possible 
  that 
  in 
  one 
  of 
  the 
  species, 
  

   S. 
  optatus, 
  the 
  number 
  of 
  these 
  joints 
  as 
  given 
  by 
  me 
  is 
  correct, 
  for 
  

   they 
  agree 
  in 
  the 
  two 
  examples 
  that 
  I 
  examined 
  ; 
  but 
  in 
  the 
  other 
  

   species, 
  S. 
  singularis, 
  one 
  more 
  example 
  of 
  which 
  has 
  lately 
  reached 
  

   me, 
  both 
  the 
  intermediate 
  and 
  posterior 
  tarsi 
  are 
  five-jointed 
  ; 
  the 
  

   examples 
  previously 
  received 
  were 
  mutilated.

   I 
  referred, 
  with 
  some 
  doubt, 
  this 
  species 
  to 
  C. 
  melancholicus, 
  Boh. 
  

   Although 
  very 
  closely 
  allied, 
  it 
  may, 
  however, 
  be 
  differentiated 
  by 
  the 
  

   length 
  of 
  the 
  supra-marginal 
  carina 
  of 
  the 
  elytra, 
  which 
  reaches 
  in 
  

   G. 
  melancholicus 
  to 
  only 
  one- 
  third 
  of 
  the 
  whole 
  length 
  of 
  that 
  part 
  of 
  

   the 
  body, 
  whereas 
  in 
  C. 
  pandion 
  it 
  is 
  very 
  sharp 
  for 
  three-fourths 
  

   of 
  the 
  length. 
  The 
  habitat 
  seems, 
  however, 
  to 
  be 
  the 
  same 
  as 
  that 
  

   of 
  C. 
  melancholicus, 
  but 
  I 
  have 
  also 
  received 
  it 
  from 
  Lourenco-

  "Mentum 
  quadrate, 
  slightly 
  rounded 
  at 
  the 
  base, 
  the 
  anterior 
  angles 
  

   obliquely 
  truncate 
  ; 
  labium 
  only 
  slightly 
  visible 
  at 
  the 
  sides, 
  on 
  

   account 
  of 
  the 
  mentum 
  being 
  truncate. 
  Labial 
  palpi 
  very 
  stout

   the 
  penultimate 
  joint 
  small, 
  as

   ovate,

  Maxillary 
  palpi 
  with 
  the 
  

   apical 
  joint 
  four 
  times 
  as

  the

  eleven 
  joints 
  ; 
  the 
  first 
  

   joint

  stout; 
  the 
  second 
  nearly 
  globular; 
  the 
  third 
  nearly 
  as 
  

   long 
  as 
  the

  sub-cylindrical 
  ; 
  the

   short, 
  and

  confounded 
  with 
  the

  joint 
  of 
  the 
  club 
  ; 
  the 
  

   ninth, 
  tenth, 
  and 
  eleventh 
  joints 
  forming 
  a 
  short, 
  ovate 
  club;

   ninth, 
  the 
  largest, 
  shining, 
  and 
  slightly 
  embracing 
  the 
  tenth 
  and 
  

   eleventh, 
  which 
  are

  a 
  canthus. 
  

   Thorax
