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 EitpJoeas resort, for a short 

 time emerging into the sunlight and exhibiting their lovely iridescent 

 colours, then returning to the favourite spot on Ayood, 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 ft is time to retire to 

 their resting places in the adjoining forest, where they spend the ni»ht. 

 It was on one of these wooden bridges that Dr. Martin obtained his first 

 E. leucoslictos. 



39. *Eupl(ea (Isamia) chloe, Guerin. 

 Distant. Butler. 



40. *Euplcea (Isamia) dkjeani, Distant. 



Distant. Moore. Mr. Distant expresses the opinion that this species 

 " May be but an extreme variety of 13. 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 £ 

 have seen no specimen agreeing exactly with Mr. Distant's figure and 

 description of E. dejeaui. 



41. *Eupl<EA {Isamia) sorim, Moore. 

 Originally described from Sumatra by Moore.

Grose Smith. Snellen. Hagen. Kirhy. Moore. A rather rare 

 species in the plains, and found on the lower slopes of the hills as high 

 as Bekantschan. The female is excessively rare. I have retained this 

 name tor the species of Isamia (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 <>ne, and moreover, that several other species kept separate by 

 Mr. Moore should be added to the synonymy.
