8. malika, de Niceville, Journ. A. S. B., vol. lxiii, pt. 2, p. 43, n. 37, pi. v, 

 figs. 18, male; 6, female (1894). 



Snellen. Grrose Smith. Kirby. This species and 5. amba, Kirby, 

 occur in the mountains rarely at higher elevations south of Bekant- 

 schan. Of S. amba Dr. Martin possesses specimens taken in April and 

 May, and again in July and August, and S. malika in March and April, 

 June and July, and October and December, so of the former there may 

 be two, and of the latter three generations in the year. 



Family PAPILIONID^E. 

 Subfamily Pierin.e. 



520. Leptosia xiphia, Fabricius. 



Snellen as nina. Wallace as nina. Hagen as nina. Distant. 

 Very weak and slow on the wing, and behaves exactly as the European 

 Leptidia (= Leucophasia) sinapis, Linnseus, does, flying near the ground 

 and seldom settling. It has been well named " The Wandering Snow- 

 flake." Occurs in open places in forests or on their margins, from 

 Selesseh to Bekantschan, rather rare than common, occurs ail the year 

 round except possibly in June, from which month Dr. Martin does not 

 possess any specimens with dates. 



521. *Demas ninus, Wallace. 



Hagen as ninus and dione. Staudinger as dione. Originally des- 

 cribed from Mount Ophir, Malacca, Malay Peninsula. Dr. Hagen 

 records it from the Karo mountains. We have not met with it. Accord- 

 ing to von Mitis (Iris, vol. vi, p. 100, n. 5 (1893), D. aglaia, Linnaeus, is 

 an older name for D. dione, Drury, that species however being con6ned 

 to the Eastern Himalayas, Assam, Burma, and China. Von Mitis 

 restricts D. ninus to the Malay Peninsula. 



522. *Delias parthenope, Wallace. 



Hagen. Mitis. Originally described from Singapore and Borneo. 

 Not obtained by us. Dr. Hagen says it is found only on the alluvial 

 plain near the sea, is the only butterfly of the mangrove forest, and 

 is even sometimes observed at sea.
