  the

   cording 
  to 
  a 
  specimen 
  communicated 
  to 
  me 
  by 
  Dr. 
  Harris. 
  Dr. 
  Melsheimer 
  describes 
  his 
  

   specimen 
  as 
  having 
  black 
  tarsi, 
  but 
  on 
  examination 
  I 
  find 
  that 
  they 
  are 
  only 
  fuscous: 
  in 
  

   most 
  specimens 
  they 
  are 
  no 
  darker 
  than 
  the 
  tibiae. 
  In 
  his 
  specimen, 
  as 
  in 
  Dr. 
  Harris', 
  

   there 
  is 
  an 
  oblong 
  fovea 
  at 
  the 
  apex 
  of 
  the 
  clypeus, 
  which, 
  however, 
  is 
  wanting 
  in 
  my 
  

   specimens. 
  There 
  can 
  be 
  no 
  doubt 
  about 
  the 
  generic 
  position 
  of 
  this 
  species; 
  it 
  only 
  

   differs 
  from 
  the 
  neighbouring 
  species 
  in 
  having 
  the 
  carina 
  of 
  (he 
  posterior 
  thoracic 
  angles 
  

   less 
  distinct. 
  

  

  A 
  variety 
  in 
  Dr. 
  Harris' 
  collection, 
  from 
  New 
  Hampshire, 
  is 
  a 
  little 
  more 
  lustrous, 
  and 
  

   lias 
  the 
  interstices 
  of 
  the 
  elytra 
  less 
  densely 
  punctulate.

  One 
  specimen, 
  Oregon. 
  Although 
  having 
  the 
  same 
  structure 
  of 
  antennae, 
  and 
  the 
  same 
  

   sculpture 
  of 
  thorax, 
  as 
  the 
  preceding, 
  this 
  species, 
  by 
  its 
  form, 
  approaches 
  very 
  closely 
  to 
  

   the 
  species 
  of 
  a 
  subsequent 
  division, 
  containing 
  C. 
  pyrrhos: 
  the 
  triangular 
  joints 
  of 
  the 
  

   antennas, 
  and 
  the 
  slightly 
  convex 
  front, 
  require 
  it 
  to 
  be 
  placed 
  in 
  this 
  division.
