  underneath 
  with 
  a 
  brownish 
  pubescence 
  ; 
  abdomen 
  with 
  a 
  

   russet-brown 
  pubescence 
  at 
  the 
  sides, 
  with 
  a 
  band 
  along 
  the 
  

   middle 
  of 
  each 
  of 
  the 
  last 
  four 
  segments 
  black 
  and 
  somewhat 
  

   velvety, 
  and 
  with 
  a 
  large 
  and 
  distinct 
  velvety 
  black 
  spot 
  on 
  

   each 
  side 
  of 
  the 
  basal 
  segment. 
  Anterior 
  tarsus 
  (male) 
  

   dilated 
  and 
  rather 
  sparsely 
  fringed 
  with 
  brownish 
  hairs, 
  with 
  

   the 
  first 
  joint 
  not 
  much 
  longer 
  than 
  the 
  second. 
  Antennas 
  

   with 
  a 
  greyish-brown 
  close 
  pubescence, 
  and 
  with 
  the 
  four 
  

   basal 
  joints 
  sparsely 
  setose 
  underneath, 
  with 
  the 
  setae 
  more 
  

   thickly 
  aggregated 
  towards 
  the 
  apex 
  of 
  the 
  scape. 
  

  

  This 
  species 
  so 
  closely 
  resembles 
  C. 
  signatipennis, 
  Lameere, 
  

   that 
  it 
  might 
  at 
  first 
  sight 
  be 
  mistaken 
  for 
  it. 
  The 
  chief 
  

   differences 
  are 
  pointed 
  out 
  above. 
  If 
  M. 
  Lameere's 
  species 
  

   is 
  the 
  true 
  signatipennis 
  of 
  Dejean, 
  as 
  I 
  have 
  no 
  doubt 
  it 
  is, 
  

   his 
  description, 
  so 
  far 
  as 
  it 
  applies 
  to 
  the 
  abdomen, 
  must 
  be 
  

   slightly 
  amended. 
  The 
  middle 
  of 
  the 
  abdomen 
  is 
  more 
  or 
  

   less 
  velvety 
  (not 
  denuded), 
  there 
  is 
  a 
  large 
  and 
  distinct 
  

   velvety 
  black 
  spot 
  on 
  each 
  side 
  of 
  the 
  basal 
  segment, 
  and 
  

   there 
  is 
  a 
  much 
  smaller, 
  somewhat 
  elongated, 
  velvety 
  black 
  

   spot 
  at 
  each 
  side 
  of 
  the 
  apical 
  segment, 
  and 
  sometimes 
  also 
  a 
  

   very 
  small 
  spot 
  at 
  each 
  of 
  the 
  antero-lateral 
  angles 
  of 
  the 
  

   intermediate 
  segments. 
  In 
  C. 
  signativentris, 
  excepting 
  the 
  

   large 
  basal 
  spots, 
  there 
  are 
  no 
  spots 
  on 
  the 
  sides 
  of 
  the 
  

   abdomen 
  ; 
  but 
  in 
  this 
  respect 
  it 
  may 
  be 
  liable 
  to 
  variation.
