pointed, very acute; exterior margin oblique and very slightly sinuous, posterior 
angle convex; cell very broad and short ; discocellulars inwardly-oblique, lower 
deeply concave. Hindwing triangularly-ovate ; anterior margin long, apex obtusely

BRUASA CHELENSIS (Plate 141, figs. 3, 3a, ¢). 
Elymnias Chelensis, de Nicéville, Journal Bombay Nat. Hist. Soc. 1890, p. 200, pl. D, fig. 3, @. 
Imaco.—Male. Upperside. Both wings fuscous-brown. forewing 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 the outer margin, the extreme outer margin ferruginous-brown. Underside ; 
both wings rich castaneous-brown, sprinkled with purplish and white strige. ore- 
wing with the white mottlings concentrated into an oblique band, which commences 
on the costa and ends at 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 dise 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 strigz, the outer area so thickly sprinkled with purplish 
confluent-strige 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, d 2;% to 2% inches. 
Hasirat.—Khasia Hills; Upper Tenasserim. 
According to Mr. L. de Nicéville this is “closely allied to Hlym. 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 
margin of both wings on the upperside being tinged with ferruginous, instead
