  Abundant 
  every 
  where. 
  I 
  was 
  at 
  first 
  inclined 
  to 
  consider 
  Say's 
  species 
  as 
  merely 
  

   identical 
  with 
  the 
  preceding, 
  but 
  as 
  in 
  the 
  description 
  he 
  says 
  that 
  the 
  first 
  and 
  second 
  

   joints 
  of 
  the 
  antenna' 
  are 
  pale 
  rufous, 
  it 
  can 
  refer 
  to 
  no 
  other 
  than 
  the 
  present 
  species. 
  

   The 
  antennae 
  are 
  more 
  strongly 
  serrate 
  than 
  usual, 
  and 
  the 
  erect 
  hairs 
  along 
  the 
  margin 
  

   are 
  very 
  distinct: 
  the 
  second 
  and 
  third 
  joints 
  are 
  equal, 
  and 
  together 
  arc 
  shorter 
  than 
  the 
  

   fourth: 
  the 
  first 
  joint 
  is 
  usually 
  piceous; 
  sometimes 
  it 
  is 
  black: 
  sometimes 
  both 
  the 
  first 
  

   and 
  the 
  second 
  joints 
  are 
  yellow. 
  The 
  posterior 
  angles 
  of 
  the 
  thorax 
  arc 
  very 
  short, 
  and 
  

   almost 
  obtuse; 
  they 
  are 
  always 
  distinctly 
  yellow: 
  the 
  anterior 
  angles 
  of 
  the 
  indexed 
  por- 
  

   tion 
  of 
  the 
  thorax 
  and 
  the 
  anterior 
  lobe 
  of 
  the 
  prosternum 
  arc 
  rufous. 
  The 
  antenna; 
  of 
  

   the 
  male 
  are 
  longer 
  than 
  the 
  head 
  and 
  thorax; 
  those 
  of 
  the 
  female 
  are 
  shorter.

  Georgia, 
  not 
  common. 
  Except 
  that 
  the 
  sides 
  of 
  the 
  thorax 
  are 
  scarcely 
  rounded, 
  and 
  

   the

  very

  no

  One 
  specimen 
  from 
  Oregon, 
  Col. 
  M'Call. 
  The 
  pubescence 
  has 
  been 
  nearly 
  destroyed 
  

   by 
  alcohol, 
  but 
  enough 
  remains 
  at 
  the 
  base 
  of 
  the 
  thorax 
  to 
  show 
  that 
  it 
  was 
  ash-coloured, 
  

   and 
  tolerably 
  dense. 
  This 
  species 
  has 
  also 
  very 
  much 
  the 
  appearance 
  of 
  a 
  Corymbctes, 
  

   but 
  the 
  anterior 
  margin 
  of 
  the 
  clypeus, 
  though 
  very 
  slightly 
  prominent, 
  is 
  perfectly 
  well 
  

   defined.

  One 
  specimen 
  from 
  San

  California. 
  This 
  species 
  is 
  less 
  elongated 
  than 
  the
