  additions 
  to 
  the 
  

  

  bluish 
  or 
  brassy 
  black, 
  colour, 
  and 
  the 
  black 
  legs, 
  palpi, 
  

   and 
  antennse, 
  the 
  two 
  basal 
  joints 
  of 
  the 
  last-named 
  

   only 
  being 
  red. 
  It 
  is 
  a 
  little 
  smaller 
  and 
  rather 
  more 
  

   oblong 
  than 
  the 
  equally, 
  but 
  more 
  sooty, 
  black 
  C. 
  mcerens 
  

   (Zimm.), 
  which 
  is 
  distinguished 
  also 
  by 
  its 
  antennse 
  

   being 
  wholly 
  black, 
  with 
  the 
  basal 
  joint 
  only 
  (very 
  rarely 
  

   the 
  second 
  also) 
  dull 
  red. 
  

  

  The 
  following 
  appears 
  to 
  be 
  nothing 
  but 
  a 
  local 
  colour 
  

   variety

  A 
  good 
  series 
  of 
  examples, 
  in 
  all 
  of 
  which 
  the 
  two 
  

   basal 
  joints 
  of 
  the 
  antennse 
  are 
  red, 
  the 
  rest 
  and 
  the 
  

   palpi 
  black. 
  The 
  sculpture 
  of 
  the 
  upper 
  surface 
  offers 
  

   no 
  constant 
  difference 
  from 
  C. 
  Hoegei 
  or 
  from 
  C. 
  cali- 
  

   fornica 
  and 
  C. 
  mexicana, 
  but 
  the 
  exterior 
  strias 
  of 
  the 
  

   elytra 
  are 
  frequently 
  more 
  faintly 
  impressed.

  This 
  Ciudad 
  form 
  of 
  the 
  black 
  C. 
  tenehrioneUa 
  bears 
  

   the 
  same 
  relation 
  to 
  its 
  type 
  as 
  the 
  metallic 
  C. 
  civitaUs 
  

   in 
  the 
  same 
  localit}^ 
  bears 
  to 
  C. 
  Hoegei. 
  The 
  basal 
  joint 
  

   only 
  of 
  the 
  antennse 
  is 
  red, 
  the 
  rest 
  of 
  the 
  antenna, 
  the 
  

   palpi, 
  and 
  legs 
  being 
  black. 
  There 
  is. 
  very 
  little 
  differ- 
  

   ence 
  between 
  C. 
  tenehrioneUa 
  and 
  C. 
  Ha'gei, 
  except 
  in 
  

   size, 
  the 
  latter 
  being 
  8—9 
  millim., 
  but 
  I 
  have 
  seen 
  no 
  

   intermediate 
  examples.
