  portion 
  behind 
  the 
  metasternal 
  lobes 
  is 
  not 
  (or 
  is 
  hardly) 
  more 
  than 
  

   half 
  the 
  greatest 
  width 
  of 
  the 
  metastethium 
  and 
  is 
  twice 
  as 
  broad 
  as 
  

   long; 
  interspace 
  between 
  mesosternal 
  lobes 
  of 
  male 
  distinctly 
  trans- 
  

   verse/ 
  as 
  broad 
  or 
  almost 
  as 
  broad 
  as 
  the 
  lobes 
  themselves; 
  of 
  the 
  

   female 
  distinctly 
  or 
  strongly 
  transverse, 
  often 
  fully 
  twice 
  as 
  broad 
  as 
  

   long, 
  generally 
  as 
  broad 
  as 
  and 
  sometimes 
  broader 
  than 
  the 
  lobes 
  them- 
  

   selves; 
  metasternal 
  lobes 
  of 
  male 
  generally 
  distinctly 
  distant, 
  occa- 
  

   sionally 
  approximate, 
  never 
  attingent; 
  of 
  the 
  female 
  generally 
  more 
  dis- 
  

   tant, 
  the 
  interspace 
  in 
  the 
  latter 
  sex 
  generally 
  as 
  broad 
  as 
  or 
  broader 
  

   than 
  the 
  frontal 
  costa. 
  Tegmina 
  never 
  fully 
  developed, 
  often 
  wholly 
  

   wanting, 
  and 
  when 
  present 
  either 
  lateral, 
  and 
  then 
  generally 
  shorter 
  

   than 
  the 
  short 
  pronotum, 
  or 
  else 
  attingent 
  or 
  overlapping, 
  and 
  then 
  at 
  

   most 
  reaching 
  the 
  middle 
  of 
  the 
  hind 
  femora, 
  and 
  usually 
  subacnminate. 
  

   Hind 
  femora 
  moderately 
  long 
  and 
  slender, 
  the 
  inferior 
  genicular 
  lobe 
  

   as 
  in 
  Melanoplus 
  and 
  the 
  spines 
  of 
  the 
  hind 
  tibiae 
  generally 
  rather 
  fewer 
  

   than 
  in 
  that 
  genus, 
  nine 
  to 
  eleven, 
  by 
  exception 
  eight 
  or 
  twelve, 
  in 
  

   number 
  in 
  the 
  outer 
  series. 
  Abdomen 
  more 
  or 
  less 
  compressed, 
  the 
  

   sides 
  of 
  the 
  Urst 
  segment 
  with 
  or 
  (in 
  some 
  apterous 
  Old 
  World 
  forms) 
  

   without 
  a 
  distinct 
  tymf)anum, 
  the 
  extremity 
  in 
  the 
  male 
  more 
  or 
  less 
  

   clavate 
  and 
  recurved; 
  subgenital 
  plate 
  of 
  very 
  variable 
  form, 
  often 
  

   prolonged 
  to 
  a 
  distinct 
  apical 
  conical 
  tubercle 
  involving 
  the 
  apical 
  

   margin, 
  the 
  lateral 
  margins 
  basally 
  anipliate; 
  cerci 
  very 
  variable, 
  but 
  

   to 
  a 
  less 
  degree 
  than 
  in 
  Melanoplus, 
  not 
  infrequently 
  stylifoim, 
  of 
  vari- 
  

   able 
  length; 
  furcula 
  usually 
  developed, 
  but 
  only 
  at 
  most 
  to 
  a 
  small 
  

   degree; 
  ovipositor 
  of 
  female 
  variable, 
  typically 
  exserted, 
  but 
  sometimes 
  

   exceptionally 
  extended 
  and 
  at 
  others 
  partially 
  withdrawn 
  in 
  the 
  then 
  

   obtusely 
  terminating 
  abdomen. 
  

  

  The 
  limits 
  between 
  this 
  genus 
  and 
  Melanoplus 
  are 
  difficult 
  to 
  formu- 
  

   late; 
  while 
  there 
  is 
  no 
  difficulty 
  in 
  separating 
  the 
  bulk 
  of 
  the 
  species 
  

   in 
  either 
  group, 
  there 
  are 
  a 
  number 
  which 
  find 
  their 
  place 
  almost 
  

   equally 
  well 
  in 
  either. 
  I 
  have 
  here 
  attempted 
  to 
  state 
  anew 
  the 
  char- 
  

   acters 
  first 
  expressed 
  by 
  Stal, 
  though 
  with 
  such 
  necessary 
  modifica- 
  

   tions 
  and 
  expansions 
  as 
  a 
  far 
  larger 
  series 
  of 
  forms 
  entails. 
  I 
  can 
  

   hardly 
  hope 
  that 
  the 
  conclusions 
  I 
  have 
  reached 
  will 
  be 
  sustained 
  at 
  

   every 
  point, 
  but 
  I 
  am 
  confident 
  that 
  they 
  must 
  hold 
  in 
  the 
  main. 
  In 
  

   doubtful 
  cases 
  I 
  have 
  endeavored 
  to 
  determine 
  the 
  affinities 
  from 
  the 
  

   concurrent 
  study 
  of 
  both 
  sexes 
  and 
  not 
  from 
  either 
  alone, 
  which 
  would 
  

   have 
  brought 
  about 
  other 
  and 
  sometimes 
  discordant 
  results; 
  and 
  I 
  

   have 
  assigned 
  the 
  greatest 
  weight 
  to 
  the 
  intervals 
  between 
  the 
  sternal 
  

   lobes. 
  

  

  As 
  I 
  have 
  here 
  employed 
  a 
  different 
  generic 
  term 
  from 
  that 
  in 
  cur- 
  

   rent 
  use 
  in 
  literature, 
  I 
  submit 
  the 
  following 
  cogent 
  reasons 
  for 
  the 
  

   necessity 
  of 
  the 
  change: 
  

  

  The 
  generic 
  name 
  Fodisma 
  was 
  proposed 
  in 
  a 
  Gallic 
  form 
  (Podisme) 
  

  

  ' 
  A 
  single 
  exception 
  is 
  known 
  to 
  me 
  in 
  the 
  siibapterous 
  Japanese 
  Podisma 
  (lairixaiua, 
  

   where 
  it 
  is 
  slightly 
  longitudinal.
