﻿BEFISIOX 
  OF 
  THE 
  MELAXOPLI—SCUDDER. 
  

  

  tlie 
  mesosternal 
  lobes. 
  The 
  tegmina 
  are 
  frequently 
  abbreviate 
  or 
  even 
  

   wanting; 
  when 
  fully 
  developed, 
  tliey 
  taper 
  gently 
  almost 
  throughout 
  

   and 
  are 
  rather 
  remotely 
  reticulate 
  at 
  least 
  in 
  their 
  apical 
  half, 
  the 
  cells 
  

   of 
  the 
  postradial 
  area 
  wholly 
  or 
  partially 
  biseriate 
  in 
  arrangement 
  on 
  

   either 
  side 
  of 
  an 
  intercalary 
  vein; 
  the 
  wings 
  are 
  almost 
  always 
  clear 
  

   and 
  uniform, 
  never 
  definitely 
  pictured, 
  the 
  veins 
  never 
  scalariform, 
  the 
  

   areolae 
  quadrate 
  or 
  longer 
  than 
  broad. 
  All 
  the 
  tarsi 
  are 
  furnished 
  with 
  

   an 
  arolium, 
  the 
  front 
  legs 
  are 
  less 
  distantly 
  separated 
  than 
  the 
  hind 
  

   pair, 
  the 
  fore 
  tarsi 
  are 
  of 
  moderate 
  length, 
  the 
  first 
  joint 
  short 
  or 
  rather 
  

   short: 
  the 
  hind 
  femora 
  are 
  distinctly 
  incrassate 
  basally, 
  generally 
  sur- 
  

   pass 
  the 
  abdomen, 
  the 
  upper 
  face 
  generally 
  smooth, 
  the 
  dorsal 
  carina 
  

   entire, 
  unarmed, 
  not 
  profoundly 
  excised 
  before 
  the 
  geniculation; 
  the 
  

   hind 
  tibiae 
  have 
  smooth 
  lateral 
  margins, 
  the 
  spines 
  of 
  the 
  outer 
  and 
  

   inner 
  J^^ries 
  are 
  equal 
  or 
  subequal 
  in 
  length, 
  those 
  of 
  the 
  outer 
  series 
  

   typically 
  nine' 
  or 
  more 
  in 
  number, 
  rarely 
  exceeding 
  fourteen, 
  placed 
  at 
  

   subequal 
  distances 
  apart 
  and 
  lacking 
  an 
  apical 
  spine 
  next 
  the 
  calcaria; 
  

   the 
  hind 
  tibiae 
  have 
  the 
  first 
  joint 
  not 
  compressed, 
  equal 
  to 
  or 
  slightly 
  

   longer 
  than 
  the 
  third, 
  the 
  second 
  much 
  shorter, 
  generally 
  a 
  half 
  shorter, 
  

   than 
  the 
  first 
  as 
  seen 
  from 
  above. 
  The 
  second 
  dorsal 
  segment 
  of 
  the 
  

   abdomen 
  is 
  neither 
  granulate 
  nor 
  dentate 
  at 
  the 
  anterior 
  angles, 
  the 
  

   extremity 
  of 
  the 
  abdomen 
  in 
  the 
  male 
  generally 
  more 
  or 
  less 
  clavate 
  

   and 
  recurved, 
  the 
  suj^raanal 
  plate 
  not 
  tuberculate, 
  with 
  a 
  basal 
  median 
  

   sulcus, 
  a 
  furcula 
  usually 
  present, 
  the 
  cerci 
  very 
  variable, 
  rarely 
  longer 
  

   than 
  the 
  supraanal 
  plate, 
  straight 
  or 
  gently 
  curved, 
  never 
  abruptly 
  

   recurved 
  basally, 
  generally 
  compressed 
  at 
  least 
  in 
  part, 
  often 
  laminate, 
  

   but 
  with 
  no 
  indirected 
  median 
  spine. 
  

  

  The 
  foundation 
  for 
  our 
  present 
  knowledge 
  of 
  the 
  structural 
  features 
  

   of 
  the 
  Melanopli 
  was 
  laid 
  by 
  StaP 
  and 
  enlarged 
  in 
  his 
  Systema 
  

   Acrideodeorum 
  (1878) 
  and 
  his 
  Observations 
  Orthopterologiques, 
  II 
  [ 
  

   (1878). 
  In 
  its 
  present 
  form 
  the 
  group 
  was 
  first 
  defined 
  and 
  named 
  by 
  

   Brunner 
  von 
  Wattenwyl,^ 
  who 
  applied 
  to 
  it 
  the 
  term 
  Pezotettiges. 
  

   I 
  have 
  here 
  limited 
  it 
  strictly 
  in 
  the 
  same 
  manner, 
  but 
  it 
  will 
  appear 
  

   that 
  it 
  contains 
  a 
  very 
  much 
  larger 
  number 
  ot 
  generic 
  types 
  than 
  were 
  

   credited 
  to 
  it 
  hy 
  Brunner 
  and 
  a 
  vast 
  multitude 
  of 
  species. 
  I 
  shall 
  

   moreover 
  show 
  below, 
  when 
  treating 
  the 
  genus 
  Podisma,^ 
  that 
  the 
  gen- 
  

   eric 
  teim 
  Pezotettix, 
  from 
  which 
  Brunner 
  derived 
  the 
  name 
  of 
  the 
  

   group, 
  has 
  been 
  misapplied 
  of 
  recent 
  years, 
  and 
  should 
  be 
  referred 
  to 
  

   the 
  group 
  called 
  Platyphymata 
  in 
  Brunner's 
  Revision. 
  I 
  have 
  accord- 
  

   ingly 
  here 
  named 
  the 
  present 
  group 
  Melanopli 
  after 
  its 
  predominant 
  

   genus 
  Melanoplus^ 
  the 
  species 
  of 
  which 
  far 
  outnumber 
  all 
  the 
  otliers 
  com- 
  

   bined. 
  Giglio-Tos 
  in 
  recent 
  papers 
  has 
  described 
  several 
  new 
  genera 
  and 
  

  

  ' 
  By 
  exception, 
  in 
  one 
  sex 
  or 
  on 
  one 
  side 
  of 
  the 
  body, 
  there 
  may 
  be 
  only 
  eight.
