  by 
  Latreille 
  ^ 
  iii 
  1825 
  for 
  short- 
  winged 
  Acridians 
  with 
  a 
  prosternal 
  spine, 
  

   without 
  specification 
  of 
  species. 
  Its 
  next 
  use 
  was 
  by 
  tlie 
  same 
  author 
  

   in 
  1829'^ 
  in 
  its 
  proper 
  Latin 
  form, 
  and 
  the 
  European 
  species 
  now 
  known 
  

   as 
  Pezotettix 
  pedestris 
  and 
  FUdyphyma 
  (jiornae 
  referred 
  to 
  it. 
  Tlie 
  same 
  

   two 
  species, 
  and 
  tliese 
  only, 
  are 
  again 
  referred 
  to 
  !*o(lis)na 
  by 
  Serville* 
  

   in 
  1831, 
  and 
  to 
  the 
  same 
  as 
  a 
  subgenus 
  of 
  Acridium 
  by 
  the 
  same 
  writer 
  

   in 
  1839.^ 
  Burmeister,^ 
  however, 
  in 
  1840, 
  refers 
  these 
  same 
  species, 
  and 
  

   these 
  only 
  to 
  a 
  new 
  genus 
  Pezotettix, 
  to 
  wbich 
  he 
  gives 
  as 
  a 
  synonym 
  

   "Podisma 
  Latreille 
  ex 
  parte." 
  In 
  Lurmeister's 
  view 
  the 
  other 
  portion 
  

   of 
  Latreille's 
  genus 
  included 
  such 
  species 
  as 
  Stenohothrvs 
  par(dlelus 
  

   and 
  Chrysochrann 
  (lispar.^ 
  But 
  these 
  latter 
  species 
  are 
  excluded 
  by 
  

   Latreille's 
  definition, 
  and 
  in 
  his 
  writings 
  I 
  can 
  not 
  find 
  that 
  he 
  has 
  ever 
  

   mentioned 
  any 
  other 
  species 
  as 
  api)ertaining 
  to 
  the 
  genus 
  than 
  the 
  two 
  

   first 
  mentioned 
  above. 
  

  

  The 
  only 
  other 
  authors 
  who 
  had 
  at 
  this 
  time 
  employed 
  the 
  term 
  were 
  

   Brulh'' 
  ' 
  in 
  1832, 
  who 
  (as 
  quoted 
  by 
  Fischer) 
  referred 
  to 
  it 
  only 
  species 
  

   of 
  StctJiophyma 
  and 
  Stenobothrus 
  ; 
  Heyer,^ 
  who 
  in 
  1835 
  (?) 
  employed 
  it 
  

   for 
  Chrysochraon 
  dispar; 
  Stephens,^ 
  who 
  in 
  1835 
  had 
  veferTed 
  jiedestris 
  

   only 
  to 
  it; 
  and 
  Costa,^" 
  who 
  in 
  1836 
  had 
  referred 
  to 
  it 
  four 
  supposed 
  

   new 
  species 
  — 
  appulum, 
  campanuni, 
  calahrum, 
  and 
  communis, 
  the 
  first 
  

   two 
  of 
  which 
  are 
  now 
  regarded 
  as 
  synonyms 
  of 
  Acridium 
  aegyptium 
  L,, 
  

   the 
  third 
  as 
  i^robably 
  a 
  Pamphagus, 
  and 
  the 
  last 
  as 
  yiornae. 
  In 
  view 
  

   of 
  the 
  limitation 
  of 
  the 
  genus 
  by 
  Serville 
  (if 
  Latreille 
  ever 
  intended 
  

   its 
  greater 
  extension), 
  this 
  action 
  of 
  Brulle 
  and 
  of 
  Costa 
  has 
  no 
  force, 
  

   and 
  hence, 
  if 
  the 
  name 
  Pezotettix 
  can 
  be 
  retained 
  at 
  all, 
  it 
  must 
  be 
  by 
  

   regarding 
  one 
  of 
  the 
  two 
  original 
  species 
  as 
  the 
  type 
  of 
  Pezotettix, 
  the 
  

   other 
  of 
  Podisma. 
  

  

  As 
  far 
  as 
  I 
  can 
  discover, 
  the 
  first 
  author 
  to 
  refer 
  the 
  two 
  species 
  to 
  

   distinct 
  genera 
  was 
  Fieber,'' 
  who 
  in 
  June, 
  1853 
  referred 
  qiornae 
  to 
  his 
  

   new 
  genus 
  Pelecyclus, 
  and 
  pedestris 
  to 
  Podisma. 
  Also 
  in 
  1853, 
  but 
  

   later, 
  his 
  introduction 
  being 
  dated 
  November, 
  H. 
  Fischer'^ 
  referred 
  the 
  

   former 
  species 
  to 
  his 
  new 
  genus 
  Platyphyma 
  and 
  the 
  latter 
  to 
  Pezotettix. 
  

   Fischer 
  has 
  been 
  generally 
  followed, 
  but 
  it 
  is 
  plain 
  that 
  Platyphyma 
  

   must 
  give 
  way 
  to 
  Pelecyclus, 
  which 
  in 
  its 
  turn 
  must 
  yield 
  precedence 
  to 
  

   Pezotettix, 
  of 
  which 
  giornae 
  becomes 
  the 
  type, 
  while 
  pedestris 
  becomes 
  

   the 
  type 
  of 
  Podisma.
