OF THE MALAYAN REGION. 39 



costal nervtire margined with, whitish near their origin ; markings of the lower wings of 

 the same tint of orange-yellow as is 0. Selena 6 , but not so glossy. 



Male not known. 



Hah. 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 

 nervTires 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. Ornithopteua 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 

 0. Pompeiis on the outer and abdominal margins, narrower on the inner margin; the 

 posterior scalloping of the yeUow patch not so deep as in 0. Fompeus, and having a 

 spot at the anal angle connected more or less with the margin. 



Tlie under surface differs from that of O. Fonipeus 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 0. Pomjjeus and 0. 

 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 yeUoAV 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. Rhadamanlhm.
