OF THE MALAYAN REGION. 39 
costal nervure margined with whitish near their origin; markings of the lower wings of 
the same tint of orange-yellow as is O. Helena 3, but not so glossy. 
Male not known. 
Hab. New Guinea, Salwatty (Wall.). 
c. Local form Celebensis.— Male : wings a little more pointed than in O. Helena; yel- 
low 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 (9 ) seems to be the more elongated 
wings, theless 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.

Remark.—The form that occurs in India, in its more elongate wings and darker 
colouring, approaches very closely to O. Rhadamanthus.
