  The 
  antennae 
  of 
  the 
  male 
  are 
  scarcely 
  so 
  long 
  in 
  this 
  species 
  as 
  in 
  

   the 
  others; 
  it 
  differs 
  decidedly 
  from 
  i?. 
  concinmts 
  in 
  the 
  bent 
  and 
  narrow 
  

   cerci 
  as 
  well 
  as 
  in 
  the 
  more 
  nearly 
  quadrate 
  interspace 
  between 
  the 
  

   mesosternal 
  lobes 
  of 
  the 
  male; 
  from 
  B. 
  pilosufi, 
  to 
  wliich 
  it 
  seems 
  more 
  

   nearly 
  allied 
  and 
  for 
  which 
  I 
  at 
  first 
  mistook 
  it, 
  it 
  differs 
  in 
  the 
  cerci 
  of 
  

   the 
  male, 
  which 
  do 
  not 
  narrow 
  before 
  the 
  middle, 
  in 
  being 
  a 
  smaller 
  

   insect, 
  besides 
  having 
  a 
  duller 
  coloring 
  with 
  more 
  contrasted 
  markings, 
  

   to 
  judge 
  from 
  Stal's 
  description.

  I 
  have 
  not 
  seen 
  this 
  species, 
  and 
  accordingly 
  give 
  St&l's 
  description, 
  

   englislied. 
  The 
  description 
  is 
  mainly 
  a 
  comparative 
  one, 
  the 
  basis 
  of 
  

   comparison 
  being 
  Aidemona 
  azteca,

  which 
  Stal 
  i)laced 
  it, 
  in 
  the 
  

   same

  of 
  Pezotettix.
