obscurely ferruginous, of a duller shade than in the forewing; three outer 

 discal pure white spots, the one in the submedian interspace square, the 

 one in the first median interspace lunular, the one in the second median 

 interspace elongated and the smallest of all ; these three spots have 

 beyond them close to the margin three other elongated white spots, with 

 a fourth anteriorly on the excavation above the anal angle ; the anal 

 lobe black, bearing a few turquoise-blue metallic scales ; the tails black 

 broadly ciliated with white. Cilia oi the forewing cinereous, of the 

 hindwing broad and pure white. Underside, both tvings as in the 

 male, except that the ground-colour is somewhat paler. 



The coloration of the specimen above described reminds one of the 

 female of '^ Myrina " orpheus^ Felder, the male of which is figured by 

 Hewitson as ^^ Myrina'^ massiva* a species from the Philippines, but 

 the female of R. aurea differs from the same sex of that species on the 

 upperside of the hindwing in having seven white spots in all instead 

 of four only. , 



I possess two males of this interesting species from Sumatra, one 

 taken at Selesseh on 14th April, 1894. The female here described 

 from Sumatra is unique in the collection of Hofrath Dr. L. Martin.

I have already (1. c.) figured and described a very remarkable aber- 

 ration or " sport " of P. sarpedon from the Battak mountains of N.-E. 

 Sumatra, in which the normal discal blue-green band of both wings 

 has entirely disappeared, except the anterior spot of the forewing which 

 •alone remains, and ^wo of the normal number of six submarginal blue- 

 green lunules (one from either end of the series) of the hindwing are 

 also wanting. Mr. J. H, Leech (1. c.) has figured and described another 

 remarkable form, which he says is the common one there, from 

 Kiukiang in Central China, in which the normal discal blue-green band 

 is wanting in the hindwing (the whitish spot in continuation thereof
