*  Mengelbir  notes  that  Pfaffenzeller  gives  **s^rtii**  as  occurring  in  the
Engadine,  but  adds  that  he  suspects  that  Pfaffenzeller  was  referriug  to  the  dark-
coloured  form  of  Z.  querctis,  the  var.  spartii  being  a  southern  form.  Pfaffenzeller
was  evidently  right ;  at  any  rate  Mengelbir  is  entirely  wrong  in  calling  spartii
a  southern  form.
