  Lake 
  Superior. 
  Though 
  the 
  thorax 
  is 
  narrowed 
  almost 
  from 
  the 
  base, 
  and 
  is 
  less 
  

   rounded 
  on 
  the 
  sides 
  than 
  in 
  the 
  preceding, 
  the 
  chief 
  character 
  for 
  distinguishing 
  them 
  is 
  

   found 
  in 
  the 
  punctuation 
  of 
  the 
  thorax, 
  which 
  is 
  here 
  much 
  finer 
  and 
  more 
  distant; 
  the 
  

   pubescence 
  instead 
  of 
  being 
  brown 
  is 
  dark 
  gray, 
  appearing 
  almost 
  black 
  in 
  certain 
  li<dits. 
  

   The 
  form 
  and 
  sculpture 
  of 
  the 
  elytra 
  are 
  as 
  in 
  E. 
  fusculus. 
  

  

  One 
  specimen 
  from 
  Eagle 
  Harbour, 
  Lake 
  Superior, 
  is 
  absolutely 
  the 
  same 
  in 
  form 
  as 
  

   those 
  above 
  described; 
  but 
  the 
  strife 
  of 
  the 
  elytra 
  are 
  deep 
  and 
  strongly 
  punctured, 
  and 
  

   the 
  antennae 
  and 
  feet 
  are 
  yellowish 
  testaceous. 
  In 
  the 
  absence 
  of 
  other 
  specimens, 
  I 
  can- 
  

   not 
  decide 
  if 
  it 
  should 
  rank 
  as 
  a 
  distinct 
  species.

  One 
  specimen, 
  Lake 
  Superior. 
  The 
  antennae 
  are 
  moderately 
  long: 
  the 
  third 
  joint, 
  al- 
  

   though 
  not 
  much 
  more 
  than 
  half 
  the 
  size 
  of 
  the 
  fourth, 
  is 
  larger 
  than 
  the 
  second 
  joint 
  : 
  

   the 
  thorax 
  is 
  not 
  longer 
  than 
  wide, 
  is 
  obliquely 
  narrowed 
  anteriorly, 
  and 
  but 
  slightly 
  

   rounded: 
  the 
  elytra 
  are 
  parallel 
  anteriorly, 
  and 
  obtusely 
  rounded 
  posteriorly: 
  the 
  tarsi 
  

   are 
  testaceous.

  Georgia,

  Lake

  In 
  appearance 
  resembles 
  E. 
  sanguinipen- 
  

   nis, 
  but 
  is 
  essentially 
  different 
  by 
  the 
  parallel 
  obtuse 
  elytra, 
  and 
  the 
  light-coloured 
  feet. 
  

   The 
  colour 
  of 
  the

  is 
  hardly 
  as 
  brilliant 
  as 
  in 
  the 
  next 
  species.

  One 
  specimen, 
  Georgia. 
  Care 
  must 
  be 
  taken 
  that 
  this 
  species 
  is 
  not 
  confounded 
  with 
  

   the 
  next, 
  to 
  which 
  it 
  bears 
  an 
  astonishing 
  resemblance. 
  On 
  comparison, 
  the 
  thorax 
  is 
  

   different 
  in 
  form, 
  being 
  but 
  little 
  rounded 
  on 
  the 
  sides: 
  the 
  punctuation 
  is 
  less 
  dense, 
  and
