  This 
  species 
  has 
  been 
  previously 
  recorded 
  only 
  from 
  New 
  Jersey 
  

   (Thomas, 
  Uhler), 
  where 
  Uhler 
  says 
  it 
  is 
  "not 
  uncommon 
  in 
  the 
  cran- 
  

   berry 
  tields 
  of 
  Atlantic 
  County;" 
  and 
  from 
  Wellesley, 
  Massachusetts, 
  

   by 
  jNIorse, 
  who 
  tells 
  me 
  that 
  his 
  specimens 
  were 
  taken 
  in 
  a 
  very 
  

   restricted 
  locality, 
  "a 
  steep 
  gravelly 
  hillside, 
  forming 
  the 
  terminal 
  por- 
  

   tion 
  of 
  a 
  part 
  of 
  the 
  gravel-plain 
  formation 
  of 
  Wellesley," 
  where 
  they 
  

   were 
  captured 
  " 
  by 
  sweeping 
  vigorously 
  the 
  short-tufted 
  growth 
  of 
  

   bunch 
  grass, 
  Andropogon 
  scoparius, 
  which 
  with 
  other 
  wild 
  grasses 
  and 
  

   running 
  blackberry 
  vines 
  sparsely 
  clothed 
  the 
  gravelly 
  soil." 
  All 
  his 
  

   specimens 
  were 
  taken 
  between 
  mid 
  July 
  and 
  mid 
  August. 
  Since 
  writ- 
  

   ing 
  me 
  this, 
  j\Ir. 
  Morse 
  has 
  found 
  another 
  locality 
  near 
  the 
  previous, 
  

   where 
  on 
  July 
  10 
  he 
  took 
  both 
  sexes 
  mature 
  and 
  nymphs; 
  the 
  surround- 
  

   ings 
  were 
  similar. 
  

  

  This 
  species 
  is 
  very 
  closely 
  allied 
  to 
  H. 
  pratcnsis, 
  but 
  differs 
  from 
  it 
  

   in 
  its 
  shorter 
  tegmina 
  and 
  wings, 
  the 
  more 
  regularly 
  conical 
  cerci 
  of 
  

   the 
  male, 
  the 
  slightly 
  different 
  form 
  of 
  the 
  supraanal 
  plate 
  and 
  the 
  

   markings; 
  it 
  is 
  also 
  of 
  a 
  smaller 
  size.
