  Pennsylvania, 
  Maryland, 
  and 
  Ohio. 
  The 
  sides 
  of 
  the 
  thorax 
  in 
  the 
  female 
  are 
  broadly 
  

   rounded 
  in 
  front, 
  while 
  in 
  the 
  male, 
  they 
  are 
  entirely 
  straight. 
  

  

  Say's 
  original 
  description 
  does 
  not 
  appear 
  to 
  be 
  sufficient 
  entirely 
  to 
  identify 
  the 
  species, 
  

   but 
  his 
  subsequent 
  remarks 
  refer 
  to 
  a 
  species 
  having 
  carinated 
  thoracic 
  angles; 
  the 
  type 
  

   in 
  Dr. 
  Harris' 
  collection 
  is 
  a 
  male 
  of 
  this 
  species. 
  The 
  antenna; 
  in 
  both 
  sexes 
  are 
  longer 
  

   than 
  the 
  thorax. 
  

  

  Melsheimer's 
  Athous 
  strigatus 
  is 
  merely 
  a 
  very 
  large 
  female 
  (-69 
  unc.) 
  of 
  this 
  species, 
  

   showing 
  no 
  specific 
  difference.

  'Easily 
  distinguished 
  by 
  the 
  rounded 
  sides 
  and 
  

   the 
  coarser 
  punctuation 
  of 
  the 
  thorax, 
  as 
  well 
  as 
  by 
  the 
  two 
  deep 
  impressions 
  half 
  way 
  

   between 
  the 
  middle 
  and 
  the 
  base. 
  The 
  specimen 
  is 
  apparently 
  a 
  female, 
  as 
  the 
  antennas 
  

   do 
  not 
  extend 
  beyond 
  the 
  base 
  of 
  the 
  thorax, 
  The 
  form 
  is 
  more 
  robust 
  than 
  the 
  pre- 
  

   ceding 
  or 
  next 
  species.

  The

  the

  red, 
  but 
  the

  The

  strongly

  Pennsylvania. 
  I 
  have 
  seen 
  only 
  the 
  typical 
  specimen 
  in 
  Dr. 
  Melsheimer's 
  collection. 
  

   The 
  antennas 
  arc 
  a 
  little 
  longer 
  than 
  the 
  thorax, 
  tolerably 
  strongly 
  serrate, 
  fuscous 
  black, 
  

   with 
  the 
  first 
  joint 
  testaceous.

  very

  form 
  and 
  general 
  appearance

  Cam-

  productus; 
  the 
  lobes 
  of 
  the 
  tarsi 
  are 
  very 
  short.
