Diese Fonn sti'lit dem PI. argus in der Farbenzeichuung ziemlich nahe, unterscheidet 

 sich aber durch die Farl^e der Fusssohle, sowie durch die viel weniger zahlreichen (nur 8) 

 und grösseren Tropfenflecke der liückenflügel. Vielleicht gehören beide Formen doch zu einer 

 Art. Gould scheint lun- ein einziges Individuum gesehen zu haben; seitdem ist über diese 

 Form Nichts liekanut geworden.

Auch diese Form, von der sonst Nichts bekannt ist, wird sich vielleicht als mit dem 

 PI. argus identisch zeigen.
