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. Pammon the males are very constant; but the females exist under three distinct forms, each of them presenting more or less numerous varieties, viz.:—
1st 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 submarginal 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 wants the red patch at the anal angle, and has the white patch formed of a row of spots all situated a little below the discoidal cell. This is the nearest approach to the first form.
