  One 
  male 
  specimen, 
  Oregon. 
  This 
  species 
  exactly 
  resembles 
  C. 
  appressifrons 
  in 
  ap- 
  

   pearance; 
  the 
  third 
  joint 
  of 
  the 
  antenna-, 
  however, 
  is 
  not 
  dilated, 
  and 
  the 
  elytra 
  are 
  

   slightly 
  obliquely 
  attenuated 
  behind 
  the 
  middle; 
  the 
  front 
  is 
  almost 
  flat, 
  and 
  the 
  declivity 
  

   commences 
  along 
  a 
  straight 
  line, 
  which 
  gives 
  a 
  quadrate 
  appearance 
  to 
  the 
  front, 
  and 
  in- 
  

   dicates 
  an 
  osculation 
  with 
  Limonius.

  I 
  have 
  only 
  seen 
  the 
  typical 
  female 
  specimen 
  in 
  Dr. 
  Melsheimer's 
  collection; 
  it 
  was 
  

   found 
  in 
  Pennsylvania. 
  The 
  antennae 
  are 
  hardly 
  as 
  long 
  as 
  the 
  thorax, 
  and 
  tin; 
  third 
  joint 
  

   is 
  not 
  at 
  all 
  dilated. 
  The 
  front 
  is 
  as 
  in 
  the 
  preceding 
  species.

  We 
  are 
  indebted 
  to 
  Dr. 
  Harris 
  for 
  the 
  discovery 
  of 
  the 
  in- 
  

   teresting 
  difference 
  in 
  form, 
  in 
  the 
  sexes 
  of 
  this 
  species. 
  

  

  For 
  the 
  reasons 
  upon 
  which 
  I 
  refuse 
  to 
  adopt 
  Germar's 
  opinion, 
  that 
  this 
  is 
  the 
  Elater 
  

   cylindriformis 
  Herbst, 
  see 
  the 
  remarks 
  under 
  Limonius 
  cylindriformis.
