The continental specimens of P. 'Pammon have all considerably developed tails in both 

 sexes ; the iasular specimens on the other hand, (which I treat as a separate species), 

 have only a prominent tooth or very short tail in the males. The females also differ 

 considerably, presenting an analogous but distinct series of forms. In the true P. Fam- 

 mon the males are very constant ; but the females exist under three distinct forms, each 

 of them presenting more or less numerous varieties, viz. : — 



\stform of female. Tab. II. fig. 3. 



This exactly resembles the male, except in the possession of a distinct ocellus at the 

 anal angle on the upper surface. Rarely a variety occurs having in addition a submar- 

 ginal row of red lunules, indicating a slight approximation towards some varieties of the 

 second form. 



2nd form of female (P. Pohjtes). Tab. II. fig. 5. 



This is by far the most common form of female. A variety of this rarely occurs, which
