  Middle 
  and 
  Eastern 
  Stales, 
  rare. 
  Germar 
  says 
  that 
  this 
  species 
  differs 
  from 
  others 
  by 
  

   its 
  longer 
  and 
  more 
  strongly 
  serrate 
  antennas. 
  It 
  is 
  true 
  that 
  the 
  antennae 
  are 
  strongly 
  

   serrate, 
  but 
  I 
  find 
  them 
  of 
  the 
  same 
  form 
  in 
  nearly 
  all 
  the 
  species 
  of 
  the 
  present 
  division 
  

   of 
  the 
  genus; 
  while 
  in 
  E. 
  linteus, 
  the 
  antenna? 
  are 
  still 
  more 
  strongly 
  serrate. 
  In 
  my 
  spe- 
  

   cimens, 
  which 
  are 
  females, 
  the 
  antenna? 
  are 
  but 
  little 
  longer 
  than 
  the 
  thorax; 
  the 
  specimen 
  

   described 
  by 
  Germar 
  is 
  said 
  to 
  have 
  antenna? 
  half 
  as 
  long 
  as 
  the 
  body, 
  and 
  is 
  certainly 
  a 
  

   male. 
  Dr. 
  Harris 
  thinks 
  that 
  this 
  is 
  E.

  m 
  a 
  Herbst; 
  a 
  species 
  placed 
  in 
  Limonius 
  by 
  

   Dejean, 
  and 
  which 
  for 
  the 
  present 
  it 
  is 
  safer 
  to 
  consider 
  as 
  indeterminate, 
  or 
  unknown.

  Middle

  The 
  only 
  differences 
  between 
  this 
  and 
  the 
  preceding 
  

   species 
  are 
  those 
  of 
  colour. 
  I 
  am 
  very 
  much 
  disposed 
  to 
  regard 
  them 
  as 
  varieties; 
  if 
  this 
  

   view 
  should 
  finally 
  prevail, 
  the 
  name 
  areolatus 
  has 
  of 
  course 
  precedence. 
  

  

  Erichson 
  has 
  committed 
  a 
  very 
  singular 
  error 
  in 
  quoting 
  Say's 
  species 
  under 
  the 
  genus 
  

   Cardiophorus, 
  (Germ.

  The 
  species 
  there 
  described

  no

  to

  This 
  is 
  the 
  smallest 
  species 
  of 
  the 
  

   genus 
  known 
  to 
  me; 
  in 
  form 
  and 
  structure 
  it 
  altogether 
  resembles 
  E. 
  obliquus, 
  except 
  

   that 
  the 
  thorax 
  is 
  more 
  regularly 
  narrowed 
  and 
  rounded 
  anteriorly, 
  and 
  that 
  the 
  second 
  

   joint 
  of 
  the 
  antenna? 
  is 
  very 
  little 
  shorter 
  than 
  the 
  third; 
  the 
  specimen 
  is 
  a 
  male, 
  and 
  has 
  

   antenna? 
  fully 
  half 
  as 
  long 
  as 
  the

  Pennsylvania. 
  I 
  have 
  only 
  seen 
  the 
  type 
  in 
  Dr. 
  Melsheimer's 
  collection. 
  The 
  third 
  

   joint 
  of 
  the 
  antenna?, 
  although 
  dilated, 
  is 
  hardly 
  one-half 
  the 
  size 
  of 
  the 
  fourth. 
  Germar's 
  

   Ampedus 
  xanthomus 
  (Zeitschr. 
  5, 
  168) 
  seems 
  to 
  agree 
  nearly 
  with 
  this, 
  but 
  the 
  size 
  

   (•25 
  unc.) 
  is 
  so 
  different, 
  that 
  I 
  cannot 
  consider 
  them 
  as 
  identical.
