c. Local form Celebensis.—Male: wings a little more pointed than in O. Helena; yellow patch of lower wings extending nearer to the posterior margin, and bounded towards the abdominal margin by the first branch of the median nervure. Beneath, having the nervures between the discoidal cell and the outer border ashy-margined.
Female not known.
Hab. Macassar (Celebes) (Wall.).
Remarks.—Of these three local modifications of O. Helena, the first is very distinct in the female, but not separable in the male sex. Of the second and third, only one sex is known; and they may very probably prove to be well-marked species when more materials are obtained.
8. Ornithoptera Leda, n. s.
Male: upper wings elongate, triangular, glossy black, quite uniform and immaculate; the outer margin delicately white-marked at the termination of the nervures. Lower wings yellow, as in the allied species, with a black border about the same width as in O. Pompeus on the outer and abdominal margins, narrower on the inner margin; the posterior scalloping of the yellow patch not so deep as in O. Pompeus, and having a spot at the anal angle connected more or less with the margin.
The under surface differs from that of O. Pompeus by the ashy margins of the veins of the upper wings being entirely absent, and in having much less white on the outer edge. There are no submarginal spots except the anal one, much red at the base of the wings, and no black spots on the abdomen.
Female: this sex varies very much, some having the upper wings immaculate, while others have the veins about the end of the discoidal cell broadly margined with whitish. The marginal series of spots on the lower wings vary as they do in O. Pompeus and O. Amphrisius. The best distinction from O. Pompeus (♀) seems to be the more elongated wings, the less crenellated margin, and the more produced outer angle of the lower wings. The yellow patch is also of a deeper colour both on the upper and under surfaces.
