  The 
  species 
  which 
  I 
  include 
  in 
  this 
  genus 
  only 
  differ 
  from 
  those 
  of 
  the 
  preceding 
  genus 
  

   in 
  not 
  having 
  the 
  second 
  and 
  third 
  joints 
  of 
  the 
  tarsi 
  obviously 
  lobed 
  ; 
  the 
  fourth 
  joint, 
  

   therefore, 
  though 
  only 
  half 
  the 
  size 
  of 
  the 
  preceding, 
  is 
  not 
  received 
  upon 
  it 
  : 
  the 
  first 
  joint 
  

   is 
  as 
  Ions 
  as 
  the 
  two 
  following 
  united. 
  

  

  This 
  genus 
  will 
  eventually 
  be 
  merged 
  with 
  the 
  preceding, 
  in 
  which 
  case 
  the 
  two 
  species 
  

   here 
  described, 
  forming 
  the 
  first 
  group, 
  having 
  the 
  posterior 
  angles 
  of 
  the 
  thorax 
  not 
  ca- 
  

   rinated,and 
  the 
  third 
  joint 
  of 
  the 
  antennae 
  equal 
  to 
  the 
  fourth, 
  will 
  enter 
  the 
  division 
  (A**,) 
  

   before 
  Pedetes 
  Brightwelli; 
  those 
  of 
  the 
  second 
  group 
  will 
  enter 
  (B**.)

  specimen 
  from 
  Oregon. 
  The 
  tarsi, 
  so 
  far 
  as 
  can 
  be 
  distinguished, 
  belong 
  

   to 
  the 
  present 
  genus, 
  and 
  the 
  characters 
  are 
  those 
  of 
  the 
  preceding 
  species: 
  the 
  sides 
  of 
  

   the 
  thorax 
  are 
  less 
  rcflexed 
  posteriorly, 
  and 
  the 
  antennas 
  are 
  somewhat 
  less 
  serrate.
