  interspace 
  between 
  mesosternal 
  lobes 
  much 
  (male) 
  or 
  a 
  little 
  (female) 
  

   longer 
  than 
  broad, 
  the 
  metasternal 
  lobes 
  attingeut 
  (male) 
  or 
  approxi- 
  

   mate 
  (female); 
  portion 
  of 
  metasternum 
  behind 
  the 
  lobes 
  about 
  twice 
  

   as 
  broad 
  as 
  long 
  and 
  about 
  half 
  as 
  broad 
  as 
  the 
  greatest 
  breadth 
  of 
  

   the 
  metasternum. 
  Tegmina 
  either 
  abbreviate, 
  broad 
  lanceolate, 
  acumi- 
  

   nate, 
  attiugent, 
  slightly 
  longer 
  than 
  the 
  pronotum, 
  or 
  fully 
  developed, 
  

   surpassing 
  the 
  hind 
  femora, 
  rather 
  broad 
  and 
  equal, 
  well 
  rounded 
  at 
  

   tip, 
  hardly 
  tapering 
  in 
  the 
  distal 
  half, 
  at 
  a 
  distance 
  from 
  the 
  ajDex 
  

   equal 
  to 
  the 
  breadth 
  of 
  the 
  tegmina 
  as 
  broad 
  as 
  the 
  metazona, 
  the 
  

   intercalaries 
  and 
  cross 
  veins 
  of 
  the 
  discoidal 
  area 
  everywhere 
  few, 
  the 
  

   venation 
  in 
  general 
  loose, 
  irregular, 
  and 
  ill-defined, 
  the 
  humeral 
  vein 
  

   broadly 
  sinuous, 
  terminating 
  on 
  the 
  costal 
  margin 
  at 
  least 
  as 
  far 
  before 
  

   the 
  apex 
  as 
  the 
  breadth 
  of 
  the 
  tegmina, 
  nowhere 
  running 
  closely 
  par- 
  

   allel 
  to 
  the 
  costal 
  margin 
  nor 
  gradually 
  merging 
  into 
  it, 
  the 
  area 
  inter- 
  

   calata 
  not 
  reaching 
  the 
  middle 
  of 
  the 
  tegmina. 
  Hind 
  femora 
  long 
  and 
  

   slender, 
  the 
  genicular 
  lobes 
  pallid 
  with 
  a 
  transverse 
  basal 
  fuscous 
  

   stripe, 
  the 
  hind 
  tibiae 
  glaucous, 
  sometimes 
  yellowish, 
  with 
  eleven 
  to 
  

   thirteen 
  spines 
  in 
  the 
  outer 
  series. 
  Abdomen 
  compressed, 
  mesially 
  

   carinate, 
  apically 
  clavate 
  and 
  recurved 
  in 
  the 
  male, 
  the 
  subgenital 
  

   plate 
  narrow 
  and 
  long, 
  with 
  lateral 
  margins 
  ampliate 
  at 
  base, 
  the 
  

   apical 
  margin 
  mesially 
  pinched 
  but 
  not 
  elevated, 
  the 
  apical 
  face 
  with 
  

   no 
  subapical 
  tubercle; 
  furcula 
  delicately 
  developed; 
  cerci 
  compressed 
  

   styliform, 
  rather 
  small; 
  ovipositor 
  of 
  female 
  normally 
  exserted. 
  

  

  This 
  genus 
  is 
  very 
  closely 
  related 
  to 
  Melanoplus, 
  from 
  which 
  it 
  is 
  to 
  

   be 
  distinguished 
  by 
  its 
  large 
  tumid 
  head 
  and 
  subsellate 
  equal 
  prono- 
  

   tum, 
  as 
  well 
  as 
  by 
  its 
  substyliform 
  cerci, 
  though 
  the 
  last 
  characteristic 
  

   is 
  found 
  in 
  some 
  degree 
  in 
  a 
  couple 
  of 
  species 
  of 
  MeJanoplus. 
  The 
  

   neuration 
  of 
  the 
  tegmina, 
  when 
  the 
  latter 
  are 
  developed, 
  also 
  differs 
  to 
  

   a 
  certain 
  degree, 
  pointed 
  out 
  in 
  the 
  descriptions. 
  Bruuer 
  ' 
  has 
  already 
  

   expressed 
  the 
  opinion 
  that 
  this 
  type 
  should 
  be 
  geuerically 
  dissociated 
  

   from 
  other 
  Melanopli. 
  

  

  A 
  single 
  species 
  is 
  known, 
  found 
  in 
  the 
  western 
  Mississippi 
  basin 
  

   and 
  beyond 
  its 
  latitudinal 
  limits 
  from 
  Alberta 
  to 
  Mexico.
