1895.] L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. 461 
All the Lanipides are very restless and quick on the wing, and never 
settle for a long time, consequently from the denseness of the plant- 
growth in the forest are not easily captured. 
370. Catochrysops strabo, Fabricius. 
Hagen as strabo , Fabricus [sic] and handarpa. Staudinger as 
handarpa. The C. handarpa of Horsfield is a synonym of C. strabo. 
371. Catochrysops lithargyria, Moore. 
First described from Ceylon, but found also in Assam, Burma, 
the Andaman Isles, and the Philippine Isles. 
372. Catochrysops cnejus, Fabricius. 
Snellen. The three species of Catochrysops in Sumatra occur at 
the lower elevations, and are not found higher than Bekantschan. The 
males of C. strabo , Fabricius, and C. lithargyria , Moore, are very com¬ 
mon on roads, where they act as miniature scavengers, but the females 
must be sought for in gardens or small jungle. The males of 0. strabo 
in particular occur in large numbers, thirty to fifty specimens, on the 
margins of puddles, and form beautiful violet patches of colour on the 
sunny roads. G. lithargyria is a little rarer than G. strabo , and may 
be considered to be a good species, Dr. Martin noting that he possesses 
females probably of this species which differ slightly in the shade of 
blue on the upperside of both wings from undoubted females of G. strabo. 
C. cnejus is quite as common as G. strabo , but is seldom found on roads 
as it prefers gardens in which the common Chinese bean ( Vigna sinensis , 
Savi.) is cultivated, on the flowers of which the larva feeds. The 
figures of G. strabo and G. cnejus in Distant’s Rkop. Malay, are not good, 
being far too reddish in shade on the upperside. The widely distributed 
G. pandava , Horsfield, which is common at Singapore, and is the most 
plentiful of all the Nicobarese butterflies, is strangely enough apparently 
absent from Sumatra. 
373. Castalius rosimon, Fabricius. 
Grose Smith. Hagen. 
374. Castalius ananda, de Niceville. 
First described from Sikliim, occurs also in Assam, Upper Burma, 
Orissa, and South India. 
375. Castalius ethion, Doubleday and Hewitson. 
Grose Smith. Snellen. Hagen. Distant.
