These 2 Marcellus were pale coloured, the light parts a dirty white; the submarginal lunules on hind wings were only two in number and small; at the anal angle was one large and one small red spot; the frontal hairs were very short. The first, or intermediate female, was also pale black, but the light parts were more green and less sordid; there were 3 large lunules; the anal red spot was double and connected, as in Telamonides; the frontal hairs short, as in Marcellus. These are the most salient points for comparing the several forms of Ajax. In nature, there is much difference in shape between Marcellus and Telamonides, still more between Marcellus and Walshii; and the latter may be distinguished from the other winter forms by the white tips of the tails. It is also smaller, and the anal spot is larger, with a broad white edging.
From lot No. 2, twenty days, came:—
1 female Marcellus, with single red spot.
1 female between Marcellus and Telamonides; general coloration pale; the lunules all obsolescent; 2 large red anal spots not connected; frontal hairs medium length, as in Telamonides.
1 female between Marcellus and Telamonides; colour bright and clear; 3 lunules; 2 large red spots; frontal hairs short.
1 female Telamonides; colours black and green; 4 lunules; a large double and connected red spot; frontal hairs medium.
2 female Telamonides; colours like last; 3 and 4 lunules; 2 large red spots; frontal hairs medium.
From lot No. 3, twenty-five days, came:—
1 male Telamonides; clear colours; 4 large lunules; 1 large, 1 small red spot; frontal hairs long.
1 female Telamonides; medium colours; 4 lunules; large double connected red spot; frontal hairs long.
In general shape all were Marcellus, the wings produced, the tails long.
From this it appeared that those exposed twenty-five days were fully changed; of those exposed twenty days, 3 were fully, 2 partly, 1 not at all; and of those exposed fourteen days, 1 partly, 2 not at all.
The butterflies from this lot of 104 chrysalides, but which had not been iced, were put in papers. Taking 6 males and 6 females from the papers just as they came to hand, Mr. Edwards set them, and compared them with the iced examples.
Of the 6 males, 4 had 1 red anal spot only, 2 had 1 large 1 small; 4 had 2 green lunules on the hind wings, 2 had 3, and in these last there was a 4th obsolescent, at outer angle; all had short frontal hairs.
Of the 6 females, 5 had but 1 red spot, 1 had 1 large 1 small spot; 5 had 2 lunules only, 1 had 3; all had short frontal hairs.
