  I 
  have 
  not 
  seen 
  this 
  species. 
  The 
  cornicles 
  seem 
  to 
  be 
  very 
  slender 
  

   for 
  an 
  Amphorophora 
  and 
  the 
  host 
  plant, 
  Austrian 
  pine, 
  is 
  very 
  

   unusual. 
  When 
  the 
  alate 
  is 
  known, 
  it 
  may 
  prove 
  to 
  belong 
  to 
  

   another 
  genus.
