  Between 
  the 
  descriptions 
  given 
  by 
  Say, 
  I 
  can 
  

   find 
  no 
  characters 
  for 
  considering 
  his 
  El. 
  lepturus 
  as 
  distinct: 
  the 
  name 
  itself 
  was 
  preoc- 
  

   cupied 
  by 
  Herbst. 
  The 
  antenna; 
  of 
  this 
  species 
  are 
  longer 
  than 
  in 
  the 
  next, 
  and 
  the 
  

   joints 
  are 
  hardly 
  transverse.

  The 
  date 
  of 
  Weber's 
  name 
  is 
  equal 
  to 
  that 
  of 
  

   Fabricius', 
  but 
  the 
  latter 
  is 
  generally 
  adopted.

  from 
  New 
  Hampshire 
  was 
  kindly 
  loaned 
  me 
  by 
  Dr. 
  Harris. 
  This 
  

   species 
  resembles, 
  in 
  form 
  and 
  general 
  characters, 
  the 
  next, 
  but 
  is 
  abundantly 
  distinct.

  Maine 
  and 
  Vermont. 
  Tbe 
  antennas 
  are 
  moderately 
  long, 
  the 
  second 
  joint 
  is 
  much 
  

   smaller 
  than 
  the 
  third, 
  and 
  the 
  following 
  are 
  transverse, 
  as 
  is 
  usual 
  in 
  this 
  genus. 
  The 
  

   pectoral 
  grooves 
  end 
  suddenly 
  near 
  the 
  anterior 
  coxse.
