  A 
  specimen 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  from 
  Montana 
  

   l^erhaps 
  belongs 
  here. 
  

  

  It 
  has 
  also 
  been 
  reported 
  by 
  McNeill 
  from 
  McLean 
  County, 
  Illinois, 
  

   and 
  Monroe 
  County, 
  Indiana. 
  

  

  This 
  species 
  is 
  remarkable 
  for 
  the 
  length 
  of 
  the 
  antennae. 
  It 
  matures 
  

   very 
  early, 
  McNeill 
  having 
  taken 
  it 
  as 
  early 
  as 
  June 
  5 
  in 
  Illinois, 
  where 
  

   he 
  thinks 
  it 
  is 
  the 
  first 
  Orthopteron 
  to 
  mature 
  from 
  eggs 
  of 
  the 
  same 
  

   season. 
  Blatchley 
  records 
  it 
  in 
  Indiana 
  even 
  as 
  early 
  as 
  May 
  11. 
  

   McNeill 
  says 
  ''it 
  is 
  by 
  no 
  means 
  common, 
  . 
  . 
  . 
  being 
  restricted 
  to 
  

   a 
  few 
  localities 
  [about 
  Moline]. 
  It 
  shows 
  a 
  decided 
  preference 
  for 
  the 
  

   sides 
  of 
  open, 
  grassy 
  ravines.'' 
  One 
  specimen 
  before 
  me 
  is 
  marked 
  by 
  

   Blatchley 
  as 
  found 
  in 
  woods. 
  

  

  The 
  species 
  has 
  never 
  before 
  been 
  described, 
  but 
  has 
  been 
  mentioned 
  

   by 
  Walsh's 
  names 
  in 
  several 
  publications; 
  the 
  specific 
  name 
  '' 
  viridu- 
  

   lus'' 
  used 
  on 
  one 
  or 
  two 
  occasions 
  was 
  a 
  misreading 
  of 
  Walsh's 
  name 
  

   "viridicrus," 
  and 
  probably 
  originally 
  due 
  to 
  bad 
  chirography 
  on 
  my 
  

   part.
