  This 
  species 
  is 
  readily 
  distinguished 
  by 
  the 
  characters 
  cited 
  in 
  the 
  

   key. 
  In 
  some 
  cases 
  the 
  anterior 
  rudiment 
  of 
  the 
  lateral 
  carina 
  is 
  

   dark 
  in 
  color 
  and 
  therefore 
  inconspicuous. 
  The 
  fore 
  femur 
  is 
  about 
  

   as 
  long 
  as 
  the 
  pronotum 
  and 
  the 
  apical 
  antennal 
  segment 
  is 
  not 
  

   over 
  one-third 
  as 
  long 
  as 
  the 
  third 
  segment. 
  This 
  species 
  has 
  no 
  

   round 
  bare 
  spots 
  at 
  bases 
  of 
  the 
  longer 
  hairs 
  on 
  venter 
  as 
  in 
  erra- 
  

   bundus 
  and 
  some 
  others.

  We 
  have 
  examined 
  several 
  European 
  specimens 
  of 
  this 
  species 
  

   which 
  agree 
  in 
  all 
  particulars 
  with 
  those 
  from 
  North 
  America. 
  

   The 
  armature

  fore

  the 
  lack 
  of 
  pronotal 
  tubercle, 
  and 
  

   the 
  shape 
  and 
  color 
  of 
  the 
  stigma 
  are 
  characteristic; 
  the 
  apical 
  

   antennal 
  segment 
  is 
  not 
  more 
  than 
  one-third 
  as 
  long

  preapical.
