  2. 
  Failure 
  of 
  the 
  character 
  of 
  relative 
  length 
  of 
  joints 
  of 
  front 
  leg 
  is 
  

  

  admitted 
  in 
  the 
  key. 
  

  

  3. 
  " 
  Usually 
  winged 
  " 
  is 
  an 
  expression 
  not 
  applicable 
  to 
  Cerascopus. 
  

  

  4. 
  Reference 
  to 
  color 
  markings 
  of 
  hemelytra 
  is 
  entirely 
  out 
  of 
  place 
  

  

  in 
  a 
  key 
  to 
  tribes 
  and 
  especially 
  when 
  both 
  sections 
  are 
  the 
  same 
  

   in 
  this 
  respect. 
  

  

  5. 
  Ploiaria 
  in 
  the 
  sense 
  of 
  Ploiariola 
  (=Empicoris) 
  is 
  the 
  inex- 
  

  

  plicable 
  but 
  frequent 
  error 
  of 
  using 
  the 
  name 
  of 
  this 
  monobasic 
  

   genus 
  for 
  a 
  species 
  not 
  the 
  genotype 
  nor 
  congeneric 
  with 
  it. 
  

  

  6. 
  There 
  are 
  no 
  one-segmented 
  tarsi 
  in 
  the 
  genera 
  named 
  by 
  Stal 
  

  

  in 
  his 
  Leistarcharia. 
  

  

  7. 
  Orthunga 
  and 
  Tinna 
  are 
  Saicinae 
  not 
  Ploiariinae. 
  

  

  8. 
  Cerascopus=Ploiaria 
  and 
  we 
  include 
  Luteva 
  as 
  congeneric. 
  

  

  9. 
  Head 
  with 
  eyes 
  scarcely 
  wider 
  than 
  apex 
  of 
  thorax 
  is 
  a 
  character 
  

  

  not 
  in 
  contrast 
  with 
  that 
  of 
  certain 
  forms 
  in 
  the 
  first 
  division 
  of 
  

   key, 
  species 
  of 
  Ploiaria 
  for 
  instance. 
  

  

  10. 
  The 
  attempt 
  to 
  define 
  the 
  tribes 
  Emesaria 
  and 
  Metapteraria 
  is 
  

  

  futile; 
  all 
  gradations 
  in 
  posterior 
  nan-owing 
  of 
  head 
  can 
  be 
  

   found 
  in 
  the 
  species 
  of 
  the 
  single 
  genus 
  Ghilianella. 
  Most 
  of 
  the 
  

   species 
  of 
  this 
  genus 
  have 
  a 
  spine 
  or 
  tubercle 
  between 
  antennae 
  

   which 
  would 
  put 
  the 
  genus 
  in 
  the 
  Metapteraria; 
  and 
  there 
  is 
  

   confessedly 
  nothing 
  to 
  depend 
  upon 
  in 
  length 
  of 
  hind 
  femur. 
  

  

  11. 
  Barce=Metapterus. 
  Stal's 
  character 
  for 
  separating 
  them 
  is 
  of 
  

  

  no 
  more 
  than 
  specific 
  importance.
