1895.] L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. 461 



All the Lampides are very restless and quick on the wing, and never 

 settle for a long time, consequently from the denseness of the plant- 

 growth iu the forest are not easily captured. 



370. Catochrtsops strabo, Fabricius. 



Hagen as strabo, Fabricus [sic] and Jcanclarpa. Staudinger as 

 kandarpa. The G. kandarpa of Horsfield is a synonym of G. strabo. 



371. Catochrtsops lithargyria, Moore. 



First described from Ceylon, but found also in Assam, Burma, 

 the Andaman Isles, and the Philippine Isles. 



372. Catochrtsops 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 G. 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 G. strabo 

 in particular occur in large numbers, thirty to fifty specimens, on the 

 margins of puddles, and form beautif al violet patches of colour on the 

 sunny roads. C. 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 O. 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 Rhop. 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 mosfc 

 plentiful of all the Nicobarese butterflies, is strangely enough apparently 

 absent from Sumatra. 



373. Castaltus rosimon, Fabricius. 

 Grose Smith. Hagen. 



374. Castalius ananda, de Niceville. 



First described from Sikhim, occurs also in Assam, Upper Burma, 

 Orissa, and South India. 



375. Castalius ethion, Doubleday and Hewitson. 

 Grose Smith. Snellen. Hagen. Distant.
