205. Ecthalia (Lexias) dirtea, Fabricius. 



Hagen. Grose Smith. Butler. Distant. Was a very common 

 species in Deli before the extension of the tobacco cultivation destroyed 

 nearly the whole of the forests ; it occurred round nearly every house, 

 and both sexes were easily captured on the kitchen-midden, especially 

 on discarded fragments of fruit thrown out by the Chinese cook. 

 Still very common behind the house of the manager of tbe Tandjong 

 Djatti Estate, where there is still left a small forest of teak (" djatti" in 

 Malay) trees. Occurs from November to March, never in high virgin 

 forest, not at a greater elevation than Bekantschan. The female is 

 called " The golden-spot butterfly" by Europeans in the Straits Settle- 

 ments. It settles with wide open-spread wings, at least when feeding. 

 Dr. Dohrn has bred it at Soekaranda. Males of this species from the 

 mountains are on the underside of both wings far darker than specimens 

 from the plains, and a little bluish in hue. 



206. Euthalia {Lexias) pardalina, Staudinger. 



Symphxdra pardalina, Staudinger, Ex. Schmetfc., p. 154, pi. liv, male [as par- 

 tialis, Standinger] (1886). 



A remarkable species, the male and female being alike, and very 

 similar on the upperside to the female of E. dirtea, Fabricius, while the 

 male of E. dirtea is entirely different from its female, and is therefore 

 quite dissimilar from that sex of E. pardalina. It is very i-are, and 

 occurs only at higher elevations, at Soengei Batoe and on the Central 

 Plateau, where E. dirtea is never found. 



207. *Ecthalia {Lexias) CYANIPARDCTs, Butler. 



Dr. Hagen informs us that he has himself captured a male of this 

 species (which has already been recorded from Borneo) near the Saentis 

 Estate in Deli, and has obtained females by his collectors from Western 

 Sumatra. 



208. Euthalia (Felderia) cocytus, Fabricius. 



Yollenhoven as ludekingii, described from Sumatra, and blumei. 

 Felder, as mitra described from Sumatra and Banca. Snellen as blumei. 

 Hagen as blumei, ludekingii, and cocytina. Grose Smith as cocytina and 

 diardi. Butler as ludelcingii. Staudinger as bhimei. Semper as ludekingii. 

 Kirby as cocytina and ludekingii. Distant as cocytina. Five species 

 of the subgenus Felderia have been l-ecorded from Sumatra by different 

 writers as enumerated above. To these names might be added 

 E. stoliczkana, Distant, E. maclayi, Distant, and E. puseda, Moore, given 

 by Mr. Distant in " Rhopalocera Malayana " from the Malay Peninsula.
