205. Edthalia ( 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 discai’ded fragments of fruit thrown out by the Chinese cook. 
Still very common behind the house of the manager of the 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. 
Symphtedra pardalina , Staudinger, Ex. Schmetfc., p. 154, pi. liv, male [as par- 
dalis, Staudinger] (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 rare, and 
occurs only at higher elevations, at Soengei Batoe and on the Central 
Plateau, where E . dirtea is never found. 
207. ^Euthalia ( Lexias) cyanipardus, 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. 
Vollenhoven as ludehingii , described from Sumatra, and blumei. 
Felder, as mitra described from Sumatra and Banca. Snellen as blumei. 
Hagen as blumei , ludehingii , and cocytina. Grose Smith as cocytina and 
diardi. Butler as ludehingii. Staudinger as blumei. Semper as ludehingii. 
Kirby as cocytina and ludehingii. Distant as cocytina. Five species 
of the subgenus Felderia have been recorded 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.
