  The 
  Neotropical 
  genus 
  P/irlcfy^<i 
  (Homoptcra: 
  Fulgoridae^) 
  was 
  

   established 
  by 
  Spinola 
  in 
  1839- 
  for 
  the 
  unique 
  species 
  Fulgora 
  dia- 
  

   dema 
  Linnaeus. 
  Since 
  that 
  time 
  various 
  species 
  have 
  been 
  described 
  

   by 
  Signoret, 
  Distant, 
  Schmidt, 
  Lallomand, 
  and 
  Metcalf; 
  in 
  1905 
  

   Schmidt 
  presented 
  a 
  key 
  to 
  the 
  known 
  species, 
  which 
  was 
  modified 
  

   by 
  Metcalf 
  in 
  1938. 
  

  

  For 
  such 
  large 
  and 
  truly 
  spectacular 
  insects 
  the 
  species 
  are 
  relatively 
  

   little 
  known 
  and 
  their 
  classification 
  is 
  in 
  a 
  confused 
  state, 
  probably 
  

   because 
  their 
  descriptions 
  have 
  Ix^en 
  extremely 
  inadequate 
  and 
  very 
  

   few 
  have 
  been 
  illustrated. 
  Specific 
  identification 
  has 
  been 
  based 
  large- 
  

   1\' 
  on 
  color 
  and 
  marking, 
  characters 
  that 
  are 
  often 
  variable 
  in 
  intensity 
  

   and 
  exactness 
  of 
  pattern, 
  wliile 
  the 
  structural 
  characters 
  generally 
  

   emphasized 
  concern 
  the 
  fmni 
  of 
  ihc 
  giDtesque 
  cephalic 
  process, 
  which 
  

   in 
  most 
  cases 
  cannot 
  he 
  adequately 
  described. 
  The 
  length 
  of 
  this 
  

   structure 
  relative 
  to 
  the 
  length 
  of 
  the 
  pronotum 
  has, 
  in 
  the 
  past, 
  

   served 
  to 
  segregate 
  llu' 
  species 
  into 
  gr(»Mi)s, 
  which 
  in 
  tiiiii 
  have 
  been 
  

   broken 
  down 
  into 
  the 
  respective 
  species 
  on 
  the 
  basis 
  of 
  color. 
  This 
  

   methofl 
  (»f 
  identification

  almost 
  a
