  Easily 
  separated 
  from 
  the 
  other 
  Nearctic 
  genera 
  by 
  the 
  greatly 
  

   inflated 
  sacs 
  on 
  the 
  pronotum. 
  Closely 
  related 
  to 
  the 
  Neotropical 
  

   genera 
  Antonae 
  St^l 
  and 
  Poppea 
  Stal 
  from 
  which 
  it 
  differs 
  by 
  the 
  

   enlarged 
  transversely 
  globose 
  sac 
  located 
  posteriorly 
  on 
  the 
  pronotum 
  

   followed 
  by 
  a 
  single 
  slender 
  process. 
  

  

  Type 
  of 
  the 
  genus, 
  Parantonae 
  dipteroides 
  Fowler 
  (1895, 
  p. 
  102), 
  a 
  

   species 
  from 
  Guatemala. 
  In 
  this 
  work 
  only 
  the 
  male 
  of 
  hispida 
  Van 
  

   Duzee, 
  a 
  species 
  found 
  in 
  Arizona 
  and 
  California, 
  has 
  been 
  available 
  

   for 
  study, 
  and 
  so 
  it 
  is 
  impossible 
  to 
  formulate 
  an 
  accurate 
  picture 
  of 
  

   the 
  type 
  of 
  male 
  genitalia 
  characteristic 
  for 
  Parantonae. 
  In 
  general, 
  

   however, 
  the 
  apices 
  of 
  the 
  styles 
  are 
  acute, 
  recurved, 
  and 
  strongly 
  

   divergent. 
  The 
  posterior 
  arm 
  of 
  the 
  aedeagus 
  is 
  short 
  and 
  thick 
  and 
  

   bears 
  rather 
  stout 
  spines 
  on 
  the 
  anterior 
  margin 
  near 
  the 
  apex. 
  Each 
  

   lateral 
  valve 
  bears 
  a 
  prominent 
  globose 
  bump 
  and 
  this 
  character, 
  if 
  

   not 
  specific 
  in 
  nature, 
  will 
  serve 
  to 
  separate 
  this 
  genus 
  from 
  its 
  closest 
  

   relatives. 
  All 
  the 
  known 
  forms 
  that 
  have 
  been 
  described 
  in 
  this 
  

   genus 
  are 
  listed:

  As 
  far 
  as 
  known 
  this 
  genus 
  is 
  not 
  represented 
  in 
  the 
  Nearctic 
  fauna, 
  

   although 
  it 
  comes 
  as 
  far 
  north 
  as 
  Central 
  America 
  and 
  southern 
  

   Mexico. 
  Because 
  this 
  genus 
  has 
  been 
  differentiated 
  from 
  related 
  

   genera, 
  notably 
  Stictocephala 
  StM, 
  by 
  the 
  single 
  criterion 
  of 
  the 
  

   presence 
  of 
  suprahumeral 
  horns 
  it 
  has 
  been 
  erroneously 
  assumed 
  

   that 
  our 
  common 
  North 
  American 
  species 
  of 
  Stictocephala 
  belong 
  in 
  

   this 
  genus. 
  The 
  genus 
  as 
  here 
  redefined, 
  with 
  greater 
  weight 
  placed 
  

   upon 
  the 
  value 
  of 
  genital 
  characters, 
  is 
  not 
  represented 
  in 
  the 
  Nearctic 
  

   and 
  the 
  great 
  majority 
  of 
  our 
  North 
  American 
  Ceresa 
  belong 
  in 
  

   Stictocephala 
  while 
  most 
  of 
  the 
  South 
  American 
  forms 
  will 
  remain 
  

   in 
  Ceresa. 
  

  

  The 
  type 
  species, 
  Membracis 
  vitulus 
  Fabricius 
  (1775, 
  p. 
  677), 
  

   originally 
  described 
  from 
  South 
  American 
  material 
  in 
  the 
  Drury 
  col- 
  

   lection, 
  has 
  not 
  been 
  examined 
  and 
  the 
  interpretation 
  of 
  this 
  species 
  

   has 
  been 
  based 
  on 
  Brazilian 
  material 
  answering 
  in 
  so 
  far 
  as 
  possible 
  

   to 
  the 
  descriptions 
  given 
  by 
  Fabricius, 
  Fairmaire, 
  St^l, 
  and 
  Fowler.
