divided bj the veins ; hindiving with from four to six placed one each 

 between the veins in a curve beyond the end of the cell. It is doubtful 

 if Mr. Distant recognised the species, as he makes no mention* of the 

 " gems," and his figure of the species does not shew them, nor does it 

 agree with my specimens of K. gemonifer, the orange band on the un- 

 derside of the forewing in true K. gemmifer being almost of equal 

 width throughout, while in Mr. Distant's figure the costal portion is 

 much narrowed and constricted. Lieut. Watson, indeed, sayst that 

 Mr. Distant's K. gemmifer equals Koruthaialos xanites, Butler, which is 

 probable enough, that species being infinitely more common than 

 K. gemmifer, the latter occurring very sparingly. 



A single example of K. fulgur, now in Dr. Martin's collection, was 

 taken Jay myself in the splendid virgin forest at Selesseh, in the Langkat 

 district of N.-E. Sumati^a, on 3]st October, 1893. Since this specimen 

 was drawn and the plates illustrating this paper made up. Dr. Martin 

 sent me in a letter a male of K. fulgur. I hope to figure and describe 

 it fully hereafter. It greatly differs from the female on the upperside 

 in the orange fascia of the forewing being much paler, more chrome- 

 yellow in shade, larger, and posteriorly continued almost to the base of 

 the wing ; and the base of the hindwing and base of the abdomen are 

 clothed with long chrome-yellow seta^

 the following opaque chrome-yellow markings : — A narrow subcostal 

 streak extending from the base of the wing to about its middle, a

 and small ones placed obliquely towards the end of the discoidal cell, 

 the upper the larger, furthest from the base of the wing, the lower 

 minute ; a dot in the lower discoidal interspace ; a spot four times as 

 large in the second median interspace ; a very large spot in the first 

 median interspace. Cilia black. Hinchtnng with a basal streak of long
