treated the form here figured as a variety, owing to the transverse black streak above the 

 anal angle on the under surface of the posterior wings containing some ochraceous markings 

 not observed in typical Javan siJocimens.

I have not received this species myself* from the Malay Peninsula, but have figured a 

 Malaccan specimen contained in the British Museum, and have copied the original description 

 of Dr. Ilorstield. 



" Surface ahove dark browa, with a very slight ferruginous lustre, being paler ou the disk and more 

 saturated at the borders ; in the hiuder pair the aual regiou is covered by a broad white patch, confined 

 posteriorly by a delicate black marginal thread, and bearing two irregularly round black spots, the 

 exterior one beiug dotted with white ; the anal appendage bears a black dash, attenuated interiorly and 

 marked laterally with a greenish silvery line; the extreme fringe of the hinder pair and the tails 

 throughout being white ; underneath the anterior win;is are fulvous, the hinder silvery white, with a broad 

 fulvous posterior border, attenuated towards the anal region, and continued by a narrow striga passing 

 irre'nilarly flexuose to the inner margin; the anterior wings are paler at the base, have an obscure 

 yellowish litura on the disk, behind this a cmwed brown striga, increasing in breadth and intensity of tint 

 towards the interior margin, and tiually a black marginal thread ; the hinder pair have a very delicate 

 linear yellowish transverse streak ou the disk, a medial band of brown dots, more saturated near the costa, 

 and continued at the inner boundary of the anal areola by a very deep black broad regularly transverse 

 streak, tending to the inner margin, and accompanied, a little above its termination, by a solitary black 

 dot ; the anal region is interiorly bounded by a series of diversified marks of an intense black colour, 

 disposed in a simple curve ; it commences, near the outer apical angle, with an oblong black streak 

 touching a wedge-shaped streak with a minute dash of green silvery irrorations at its inner extremity ; 

 this is followed by two large irregularly defined black spots, which also appear on the upper surface, 

 the exterior one being bordered at its inner margin by a crescent of silvery irrorations, the next divided 

 into two portions by the passage of the fulvous striga, bearing near the middle two silvery lunules opposed 

 to each other ; the series is terminated by a black streak, extending in contact with the fulvous band along 

 the oblique portion of the inner margin, being nearly concealed by a corresponding streak of silvery 

 irrorations ; the anal appendage is black, and surrounded by a lax ciliated white fringe which is broader 

 internally ; the tltora.v and abdomen are brown above and white underneath, the latter being banded at the 

 sides ; the feet are white, annulated with black ; the antcnnce are also delicately annulated, and the club 

 has a broad white ring at its base and a ferruginous tip."

Dr. Horsfield's description evidently applies to a female specimen, and of the male sex 

 I can find no account. It probably has a bluish gloss above, and is evidently ahied to the 

 preceding species. What is the female of S. nahjmond! and what is the male of S. chitra'^ 

 There is certainly no great reason why the two species (?), as at present known, should not be 



* Since this was WTitteu I have rucei\ed a female specimen from tjuugei Ujong, which has enabled me to certify 

 its generic position.
