median in both sexes has its inner edge always incurved, the two lower portions 

 being also much narrower and dentated outward on both sides, whereas in true 

 Ismene the inner edge of the median discal portion is always more or less excurved ; 

 the portion between the lower median and submedian, in the female, is dentated 

 outward exteriorly and inward on its opposite side ; the outer transverse markings 

 more prominently defined on both wings. Underside with the discal white band 

 as on the upperside.

 the discal transverse white band similar to that in the wet-season brood, its 

 contiguous outer sinuous line slender ; the basal marks and the submarginal sinuous 

 line less apparent ; the outer border of forewiug very densely powdered with grey 

 scales, and on the hind wing the inner discal blackish dentated marks are slender 

 and obscure, the outer discal row being obsolescent. Underside much paler than in

Habitat. — Khasias ; Burma ; Tenasserim ; Siam. 



Distribution. — The Fabrician type of Martha — a small female of the wet-season 

 brood — is recorded from Siam ; a male of the wet-season brood in the British Museum 

 Collection was recently taken by Mr. H. N. Ridley on Lankawi Island, Coast of Siam, in 

 January. The type specimens of attenuata were taken by Mr. Otto Limborg at Hatseiga 

 and on the road from Naththoung to Paboga, in Upper Tenasserim, during the cold 

 season. Specimens of both sexes of the wet-season brood from the Khasias, which we 

 have identified as this species, are in Col. C. Swinhoe's collection. Capt. E. Y. Watson 

 found it " common at Beeling, Upper Tenasserim" (J. Bombay N. H. Soc. 1888, 5). 

 There are specimens in the British Museum, taken by Capt. Watson at Tiling Yaw 

 in January, April and October, during the Chin Lushai Expedition, and in the 

 Karen Hills in December. Mr. Moti Ram took it at " Ponsekai in Upper Tenasserim " 

 (J. A. S. Beng. 1887, 424-). Capt. C. T. Bingham obtained the male of wet-season form 

 at Moulmeiu in October, and at Houndraw in November ; also in the Donat Range 

 and Upper Thoungyeen forests in Upper Tenasserim in October. A female from 

 Tavoy Valley, taken in April, and a male wet-season form from Karen Hills, is in 

 Mr. P. Crowley's collection. Lieut.-Col. C. H. E. Adamson (List, 1897, p. 22) records 

 specimens agreeing with attenuata from Rangoon and Moulmein. We possess a 

 female of the dry-season form from Mahatauug, taken in February, and also a male
