  its 
  real 
  affinities 
  are 
  with 
  the 
  two 
  preceding 
  spe- 
  

   cies, 
  from 
  which 
  it 
  differs 
  by 
  its 
  more 
  convex 
  and 
  coarsely 
  punctured 
  thorax. 
  The 
  elytra 
  

   are 
  somewhat 
  obliquely 
  narrowed 
  posteriorly, 
  and 
  more 
  strongly 
  margined 
  than 
  in 
  the 
  

   two 
  preceding. 
  The 
  first 
  joint 
  of

  One 
  specimen, 
  Oregon. 
  Although 
  evidently 
  allied 
  to 
  the 
  others 
  in 
  this 
  division 
  the 
  

   third 
  joint 
  of 
  the 
  antennae 
  is 
  considerably 
  narrower 
  than 
  the 
  following 
  ones: 
  the 
  curious 
  

   reflexed 
  margin 
  of 
  the 
  anterior 
  thoracic 
  angles 
  will 
  easily 
  distinguish 
  this 
  species: 
  the 
  

   sides 
  of 
  the 
  thorax 
  are 
  almost 
  straight, 
  slightly 
  rounded 
  at 
  the 
  apex, 
  and 
  before 
  the 
  basal 
  

   angles: 
  the 
  first 
  joint 
  of 
  the 
  tarsi 
  is 
  slightly 
  longer 
  than 
  the 
  second. 
  

  

  Asaphes 
  Kirby. 
  

  

  Although 
  but 
  one 
  species 
  of 
  this 
  genus 
  is 
  described 
  by 
  Kirby 
  and 
  another 
  by 
  Germar 
  I 
  

   find 
  that 
  several 
  of 
  our 
  Elaters 
  possess 
  characters 
  which 
  require 
  them 
  to 
  be 
  associated 
  

   with 
  his 
  type. 
  They 
  seem 
  to 
  form 
  a 
  natural 
  group 
  approaching 
  most 
  nearly 
  to 
  Corym- 
  

   bites, 
  and 
  indeed 
  differing 
  from 
  that 
  genus 
  only 
  in 
  the 
  structure 
  of 
  the 
  tarsi. 
  The 
  second 
  

   and 
  third 
  joints 
  of 
  the 
  tarsi 
  are 
  dilated 
  beneath 
  into 
  a 
  short 
  spongy 
  lobe: 
  the 
  first 
  joint 
  is 
  as 
  

   long 
  as 
  the 
  second 
  and 
  third 
  together, 
  and 
  usually 
  spongy 
  at 
  the 
  tip: 
  the 
  fourth 
  joint 
  is 
  

   small 
  and 
  narrow, 
  received 
  upon 
  the 
  third, 
  and 
  is 
  sometimes 
  also 
  spongy 
  beneath: 
  the 
  fifth 
  

   joint 
  is 
  elongate 
  with 
  simple 
  claws. 
  

  

  Our 
  species 
  may 
  be 
  grouped 
  according 
  to 
  the 
  presence 
  or 
  absence 
  of 
  the 
  basal 
  fissures 
  

   and 
  carina? 
  of 
  the 
  thorax. 
  The 
  third 
  joint 
  of 
  the 
  antenna? 
  is 
  more 
  or 
  less 
  dilated 
  and 
  

   usually 
  but 
  little 
  smaller 
  than 
  the 
  fourth. 
  The 
  first 
  group 
  osculates 
  with 
  Corymbites: 
  

   the 
  second 
  with 
  Athous 
  and 
  Pedetes.

  One 
  specimen, 
  Maryland, 
  Prof. 
  Adams: 
  a 
  curious 
  robust 
  species 
  which 
  exhibits 
  a 
  won- 
  

   derful 
  resemblance 
  to 
  Corymbites 
  crassus 
  above 
  described. 
  The 
  transverse 
  wrinkles 
  of 
  

   the 
  thorax 
  are 
  not 
  mentioned 
  by 
  Say, 
  and 
  are 
  possibly 
  not 
  constant. 
  The 
  elytra 
  have 
  

   four 
  broad 
  faint 
  impressions, 
  producing 
  a 
  slight 
  elevation 
  about 
  the 
  middle, 
  nearer 
  to 
  the 
  

   side 
  than 
  to 
  the 
  suture: 
  the 
  third 
  joint 
  of 
  the 
  antennas 
  appears 
  to 
  be 
  about 
  the 
  same 
  size 
  

   as 
  the 
  fourth, 
  and 
  hardly 
  narrower.
