518. Sinthusa AMBA, Kirby. 
Originally described from Malacca, occurs also in Burma. 
519. Sinthusa malika, Horsfield. 
S. malika, de Niceville, Journ. A. S. B., vol. lxiii, pt. 2, p. 43, n. 37, pi. v, 
figs. 18, male; 6, female (1894). 
Snellen. Grose Smith. Kirby. This species and S. 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 Pjerinj&. 
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 (= Leueophasia) sinapis, Linnaeus, 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 all the year 
round except possibly in June, from which month Dr. Martin does not 
possess any specimens with dates. 
521. ^Delias 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 confined 
to the Eastern Himalayas, Assam, Burma, and China. Yon 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.
