12 L. de Nic^ville — BiiUerflies from the Indo-Malayan region, [No. 1, 



defined as in the forewlng", pure wbite ; the broad whitish discal fascia 

 beyond bearing a series of prominent black lunnles. Undeeside, both 

 ivings as in the male. 



The male of E. eion may be known from the same sex of E. teuta, 

 Doubleday and Hewitson, which appears to be confined to Assam and 

 Northern Burma, by the subapical spot of the forewing on the upper- 

 side being smaller, and by the presence of the submarginal series of 

 seven decreasing white spots on the hindwing. The female is at once 

 distinguished by the broad whitish fascia across both wings on the up- 

 perside beyond the discal macular band, also by the spots of the latter 

 being smaller and well separated. E. teuta has been recorded by 

 Mr. Moore from Java and by Mr. Druce from Borneo. It is doubtful 

 if it occurs in either island, the Javan species being E. eion, and the 

 Bornean E. bellata, Druce. 



Described from two males and two females in my collection, received 

 from Mr. H. Fruhstorfer, and one male in the collection of Herr George 

 Semper, taken in February.

Description : Male. Upperside, loth ivings pale clear brown, all 

 the veins fuscous and prominent. Foreiving with a small dark round 

 spot in the middle of the discoidal cell touching the subcostal nervure ; 

 two fine black lines on either side of the disco-cellular nervules ; a 

 discal series of eight semi-transparent pale yellow spots, each spot 

 outwardly bounded by a fuscous line, which line is inwardly lengthen- 

 ed out into a point, the three anterior siDots lengthened, the fourth and 

 fifth in the median interspaces pyriform, the apex of each spot directed 

 towards the base of the wing, two small spots in the submedian inter- 

 space, a minute one in the sutural area ; beyond this series of spots is 

 a pale fascia, prominent at the inner margin, becoming lost anteriorly 

 at a small pale yellow spot in the subcostal interspace ; this pale band 

 is outwardly defined by a highly lunulated fuscous line, anteriorly 

 becoming obsolete. Hindwing bearing a discal series of eight spots, 

 the three anterior ones white, the others pale yellow, these five latter are 

 each outwardly defined by a fuscous line, the uppermost spot on the 

 costa narrow, elongated, the second spot the largest, rounded, the third 

 a little smaller, oval, the next four small, equal-sized, the eighth posterior 

 spot the smallest ; a submarginal series of seven sagittate fuscous mark-
