Imago. — Male. Upperside. Both wings fuscous-brown. Forewitig with the 

 basal half of the costal and the outer margin narrowly ferruginous brown, the rest of 

 the wing strongly glossed with rich deep blue, becoming obsolete basally ; two large 

 conjoined equal-sized oblong upper discal pale blue spots, and three similar but 

 smaller lower spots in the median interspaces, the lowest being sometimes obsolete. 

 Hindwing entirely unglossed with blue, the fuscous ground-colour becoming lighter 

 towards tbe outer margin, the extreme outer margin ferruginous-brown. Underside ; 

 both wings rich castaneous-brown, sprinkled with purplish and white strigce. Fore- 

 wing with the white mottlings concentrated into an oblique band, which commences 

 on the costa and ends rfit the first median veinlet, where the speckles are more 

 scattered and larger, and with the mottling extended one-fourth along the costa from 

 the apex ; inner margin dull fuscous, extending on to the disc beyond the oblique 

 discal mottled-band and ending in a point on the third median veinlet. Hindwing 

 divided into two equal well-defined areas, the basal area rich castaneous, sparsely 

 sprinkled with dull purplish striga3, the outer area so thickly sprinkled with purplish 

 confluent-striga3 that the castaneous ground-colour is almost obliterated; a large 

 oval pale ochreous spot in the middle of the upper subcostal interspace ; an outer 

 discal or submarginal series of five minute black dots inwardly marked with a 

 minute white dot, one in each interspace. 



Expanse, <S 2^^^ to 2^^o inches. 



Habitat. — Khasia Hills ; Upper Tenasserim. 



According to Mr. L. de Niceville this is " closely allied to Ehjm. penanga 

 [mehida, Hewitson] from the Malay Peninsula, from which it differs in the 

 apex of the forewing being more produced, the outer margin much less 

 sinuous, the apex of the hindwing also more produced, the outer margin con- 

 siderably truncated and entire ; in the costa of the forewing and of the outer 

 niaigin of both wings on the upperside being tinged with ferrugiuou.=?, instead
