376 L. dc Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 
the direct sunlight, especially where there is dead wood, so that they may 
frequently be found in the open verandahs of houses near the forest, or 
on wooden bridges over rivers, which in Sumatra are almost always 
furnished with an attap roof made of palm leaves to protect the wood¬ 
work from the rain. To these places do the Euploeas resort, for a short 
time emerging into the sunlight and exhibiting their lovely iridescent 
colours, then returning to the favourite spot on wood, where they rest 
with folded wings ; this evidently much-enjoyed sport of the butterflies 
continuing the whole day till three or four o’clock in the afternoon, 
when the lengthening shadows warn them that it is time to retire to 
their resting places in the adjoining forest, where they spend the night. 
It was on one of these wooden bridges that Dr. Martin obtained his first 
E. leucostictos. 
39. # Eupiaea ( Isamia ) CHLOE, Guerin. 
Distant. Butler. 
40. # Euplcea ( Isamia ) dejeani, Distant. 
Distant. Moore. Mr. Distant expresses the opinion that this species 
“May be but an extreme variety of E. chloe ,” Guerin, which latter by 
Mr. Moore is restricted to Province Wellesley in the Malay Peninsula. 
I am also of this opinion, but keep it distinct for the present, as I 
have seen no specimen agreeing exactly with Mr. Distant’s figure and 
description of E. dejeani. 
41. *Eupl<ea ( Isamia ) sophia, Moore. 
Originally described from Sumatra by Moore.

E. fegyptus, Snellen, Midden-Sumatra, Lepidoptera, p. 12, n. 2, pi. i, fio- s l _3 
male (1892). 
Grose Smith. Snellen. Hagen. Kirby. Moore. A rather rare 
species in the plains, and found on the lower slopes of the hills as hio'h 
as Bekantschan. The female is excessively rare. I have retained this 
name for the species of Isaruia (I have been able to recognise only one) 
occurring in Sumatra, as so many authors have identified the Sumatran 
form of E. chloe , Guerin (which is the oldest name for the species of 
this group) under it. But I am very strongly of opinion that instead 
of four species of Isamia as recorded above occurring in Sumatra there 
is only one, and moreover, that several other species kept separate by 
Mr. Moore should be added to the synonymy.
