The continental specimens of P. Pammon have all considerably developed tails in both 
Sexes; the insular 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. Pam- 
mon the males are very constant; but the females exist under three distinct forms, each 
‚of them presenting more or less numerous varieties, viz. :— 
lst form 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. Polytes). . Tab. II. fig. 5. 
This is by far the most common form of female. A variety of this rarely occurs, which
