   placed 
  by

  under 
  

   the

  Sufficiently 
  distinct 
  from 
  any 
  other 
  species 
  herein 
  described, 
  and 
  

   apparently 
  more 
  nearly 
  related 
  to 
  C. 
  asthiops; 
  the 
  third 
  joint 
  of 
  the 
  antennas 
  is 
  triangular, 
  

   as 
  long, 
  but 
  only 
  half 
  as 
  wide 
  as 
  the 
  following, 
  which 
  are 
  acutely 
  triangular, 
  but 
  not 
  pro- 
  

   duced 
  at 
  the 
  angle; 
  the 
  eleventh 
  joint 
  is 
  not 
  longer 
  than 
  the 
  tenth, 
  not 
  acuminate, 
  but 
  

   still 
  distinctly 
  constricted.

  One 
  specimen, 
  found 
  on 
  the 
  north 
  shore 
  of 
  Lake 
  Superior. 
  Mr. 
  Randall 
  found 
  it 
  in 
  Maine: 
  

   Kirby's 
  specimen 
  was 
  found 
  in 
  lat. 
  65°. 
  The 
  thorax 
  is 
  so 
  deeply 
  and 
  broadly 
  channelled 
  

   that 
  the 
  disc 
  appears 
  longitudinally 
  elevated 
  each 
  side: 
  the 
  antennas 
  of 
  the 
  male 
  are 
  pec- 
  

   tinate.

  Very 
  similar 
  to 
  the 
  next,

  is 
  more

  the
