Habitat : Nias {Kheil) ; ]^,-E. Sumatra. 

 Expanse : <^, 1-0 to 1*2 ; $,1-1 to 1-2 inches. 

 Desceiption : Male. Uppeeside, both wings light metallic azure- 

 blue of the same shade as L. elpis, Godart ; the white markings of the 

 underside showing through by transparency. Foreiving with the costa 

 towards the base of the wing very narrowly black ; the apex widely 

 black ; the outer margin also widely but decreasingly black. Hind- 

 wing with a marginal series of increasing black spots ; an anteciliary 

 black thread divided from the marginal spots by a white thread ; from 

 the first median nervule to the abdominal margin anterior to the 

 marginal spots is first a fine black, then a fine white, line. Under- 

 side, both wings pale dull plumbeous ; three continuous marginal 

 nearly straight white lines. Foreiving with four discal parallel white 

 lines arranged at equal distances apart as in L. elpis^ the two internal 

 ones spring from near the subcostal nervure and reach the submedian 

 nervure, with two white dots anteriorly on the costa ; the third line 

 commences on the costa and ends on the second median nervule ; the 

 fourth line commences on the costa and ends on the third median 

 nervule. Hindioing with the usual basal and discal lines ; a large 

 rounded black spot in the first median interspace surrounded on three 

 sides by ferruginous, bearing at its posterior inner corner a few 

 metallic green scales ; there is also a small clump of similar scales on 

 the margin in the submedian interspace placed on a black spot, which 

 latter is crowned with ferruginous. Female. Upperside, both wings 

 of a paler shade of blue than in the male with no metallic lustre. 

 Forewing with the whole of the costa narrowly black ; the apes and 

 outer margin with the black border twice as wide as in the male. 

 Hindwing with an inner rather broad marginal lunulated black line, 

 then a prominent more or less rounded series of black spots defined on 

 both sides by a white line, then an anteciliary black thread. Undee- 

 SIDE, both ivings as in the male. 



Although this species bears a strong superficial resemblance to the 

 widely-distributed L. elpis, I believe it to be quite distinct. It is 

 much smaller ; the black border of the male on the upperside of the 

 forewing is actually wider than in any specimen of L. elpis in my
