  obtusely 
  and 
  bluntly 
  angulate; 
  lateral 
  lobes 
  vertical, 
  their 
  lower 
  border 
  

   very 
  obtusely 
  angulate 
  in 
  the 
  middle. 
  Prosterual 
  spine 
  prominent, 
  

   subcylindrical, 
  bluntly 
  pointed, 
  laterally 
  compressed 
  at 
  the 
  base, 
  at 
  

   least 
  in 
  the 
  male: 
  mesosternal 
  lobes 
  narrowly 
  separated 
  in 
  both 
  sexes; 
  

   metasternal 
  lobes 
  subattingent 
  (male) 
  or 
  as 
  distant 
  as 
  the 
  mesosternal 
  

   lobes 
  (female). 
  Tegmina 
  and 
  wings 
  variable, 
  but 
  at 
  least 
  as 
  long 
  as 
  

   the 
  i)ronotum. 
  Hind 
  femora 
  reaching 
  or 
  generally 
  surpassing 
  the 
  tip 
  of 
  

   the 
  abdomen, 
  moderately 
  stout 
  but 
  tapering 
  very 
  regularly, 
  unarmed 
  

   above, 
  the 
  inferior 
  genicular 
  lobes 
  produced 
  but 
  apically 
  rounded, 
  

   marked 
  at 
  base 
  with 
  a 
  transverse 
  dark 
  bar; 
  spiued 
  margins 
  of 
  hind 
  

   tibiae 
  smooth, 
  scarcely 
  dilated 
  toward 
  the 
  tip, 
  provided 
  on 
  outer 
  margin 
  

   with 
  nine 
  to 
  thirteen, 
  generally 
  eleven, 
  spines, 
  the 
  larger 
  number 
  being- 
  

   more 
  common 
  in 
  the 
  female. 
  Subgenital 
  plate 
  of 
  male 
  short, 
  transverse, 
  

   of 
  subequal 
  width 
  throughout, 
  more 
  or 
  less 
  tumid, 
  the 
  lateral 
  margins 
  

   ampliate 
  at 
  the 
  base; 
  anal 
  cerci 
  of 
  male 
  long, 
  laminate, 
  subclepsydral 
  

   ill 
  shape, 
  incurved; 
  edges 
  of 
  inferior 
  valve 
  of 
  ovipositor 
  smooth. 
  

  

  This 
  genus 
  bears 
  a 
  close 
  general 
  resemblance 
  to 
  the 
  gerontogeic 
  

   genus 
  Oxya, 
  but 
  differs 
  strikingly 
  from 
  it 
  in 
  the 
  separated 
  metasterual 
  

   lobes 
  of 
  the 
  female, 
  the 
  blunt 
  tips 
  of 
  the 
  inferior 
  genicular 
  lobes 
  of 
  the 
  

   hind 
  femora, 
  the 
  smooth 
  edges 
  of 
  the 
  hind 
  tibiae 
  and 
  the 
  absence 
  of 
  

   the 
  terminal 
  spine 
  of 
  the 
  outer 
  series 
  of 
  the 
  same. 
  It 
  is 
  very 
  narrowly 
  

   separable 
  from 
  Melanoplus, 
  and 
  I 
  do 
  not 
  see 
  how 
  it 
  could 
  be 
  distin- 
  

   guished 
  from 
  it 
  if 
  we 
  include 
  in 
  it, 
  as 
  Stitl 
  did, 
  his 
  Fezotetfix 
  plebejus 
  

   and 
  rusticns. 
  The 
  combination 
  of 
  such 
  peculiarities 
  as 
  the 
  long 
  

   antennae 
  and 
  strongly 
  transverse 
  subgenital 
  i)late 
  of 
  the 
  male 
  with 
  

   the 
  long 
  and 
  parallel-sided 
  pronotum 
  of 
  both 
  sexes 
  serves 
  to 
  distin- 
  

   guish 
  it 
  from 
  Melanoplus, 
  as 
  here 
  limited; 
  while 
  the 
  strongly 
  banded 
  

   sides 
  of 
  the 
  body 
  and 
  the 
  long 
  and 
  clepsydral 
  cerci 
  of 
  the 
  male 
  in 
  all 
  

   the 
  species 
  mark 
  it 
  as 
  a 
  peculiar 
  type 
  even 
  if 
  these 
  markings 
  and 
  form 
  

   of 
  genitalia 
  do 
  occur 
  in 
  certain 
  species 
  of 
  the 
  diversified 
  genus 
  

   Melanoplus. 
  

  

  Three 
  species 
  are 
  known 
  and 
  appear 
  to 
  be 
  confined 
  almost 
  entirely 
  to 
  

   our 
  Atlantic 
  and 
  Gulf 
  borders, 
  though 
  some 
  of 
  the 
  species 
  occur 
  as 
  far 
  

   inland 
  as 
  Indiana, 
  Ohio, 
  and 
  Michigan. 
  It 
  is 
  unknown 
  west 
  of 
  the 
  

   Mississippi, 
  except 
  in 
  Louisiana 
  and 
  Texas 
  (though 
  Professor 
  Bruner 
  

   suspects 
  its 
  presence 
  in 
  i^ebraska). 
  They 
  inhabit 
  moist 
  places. 
  

  

  The 
  type 
  is 
  P. 
  floridana.
