176 Journal of the F.M.S. Museums. [Vol. X, 



A female from Mt. Kinabalii, British North Borneo, 

 in the Raffles Museum, is very similar to one from the 

 island of Krakatau (between Java and Sumatra) in the 

 Buitenzorg Museum. The white spots in the hind-margin 

 of the hind wing are slightly more pronounced above and 

 below in the latter specimen and in two males from the 

 same locality.

A common form throughout the Malay Peninsula, 

 Sumatra, Borneo and the Natuna Islands, with other sub- 

 species ranging as far as India, Java and Celebes. In 

 Malaysia the following subspecies are recognized : — 



D. m. melanippus Cr. Java.

Suinatra and Xatur.a Is.

Of 60 specimens in the F.M.S. Museums, 43 are males, 

 17 females. In tlie Raffles Museum there are 11 males and 

 3 females. Apparently on the wing all the year round. 



Tliere is a melanistic tendency noticeable in the hind 

 wings of certain males which have the white post-ceUular 

 streaks, especially those immediately above the scent-patch, 

 much reduced. These are typical hegesippus, but there are 

 several examples in the above series which agree admirably 

 with Fruhstorfer's figure of D. m. indicus.' This form he 

 lestricts to Tenasserim, Burma, Bengal and Cochin-China. 

 (iodfrey - regards the Siamese form as hegesippus. The 

 three he sends me are typical hegesippus, differing particu- 

 larly from Fruhstorfer's figure of indicus in the reduced 

 sub-apical white markings of the fore wing. I doubt 

 whether the Indian form can be maintained as a separate 

 subspecies. 



24a. Danaida melanippus Cr. insulan's subsp. nov 



Differs from .lavan mehinippus in the hind wing, 

 which is noticeable for its white cell, contrasting with three 

 pale ferruginous streaks bordering the submedian and 

 internal neivurcs. The post-cellular streaks are white and 

 much reduced, but shaded posteriorly with ferruginous 

 scales ; the white spots of the hind-marginal border are 

 reduced. The whole of the discal region of the hind wing 

 below is pale ferruginous, not white as in hegesippus.
