LAMPIDINM 87 



interspace 2, the largest and capped with orange, this series is followed by a blackish 

 angular band (touching it) capped with indistinct whitish lunules, both wings with 

 black terminal line. Underside as in the male, the outer markings large and very- 

 prominent. 



Expanse of wings, $ % Iro to l-^ inches. 



Habitat. — Burma, Nicobars, Borneo, Amboina, Alu. 



Distribution. — Felder's type, which we have examined, came from Amboina, 

 Druce's type from Borneo, H. H. Druce's types from Alu Island, Rubiana Island, 

 Malaita Island, and Uluana Island ; Elwes records it from Eastern Pegu, and Bingham 

 from Burma, Tenasserim and the Nicobars ; we have several examples from Alu Island 

 and Tenom, British N. Borneo ; they vary much in size from the different localities, 

 but cannot be specifically separated,

Imago. — Male. Forewing triangular, costa long, quite a fifth longer than the

 Hindwing with the apex well defined, outer margin nearly straight to vein 3, the anal

 slight pinkish tinge, bands not darker than the ground colour, indicated by their white 

 edgings. Foreiving with a bar across the middle of the cell, extends hindwards to 

 vein 1, a bar across the end of the cell, a discal band of four conjoined bars from near 

 the costa to vein 8, extended hindwards from its inner side to vein 1 ; the bar above 

 vein 3 a little disjointed inwards. Hindwing with a sub-basal band, a bar across the 

 end of the cell, and a discal outwardly curved band of bars, the fifth from the costa a 

 little inwards, touching the lower end of the discoidal bar ; both wings with terminal 

 brown line, and a double series of sub-terminal white lunules filled in with pale brown,
