ON NEW AND LITTLE-KNOWN BUTTERFLIES. 261 



A reference to Hewitson's, Westwood's, and Distant's figures of 

 Melanocyma faunula, Westwood, all taken from female specimens, 

 will at once reveal the many important characters in which that species 

 differs from the present one, which characters are also borne out by 

 the numerous specimens of M. faunula I possess from several localities 

 in the Malay Peninsula and from Ohentaboon in Siam. The ground- 

 colour in M. fammla is almost white on the upperside of the hind- 

 wing, instead of being concolorous with the forewing ; the yellow 

 colour is more extensive also, reaching to the second median nervule, 

 in M. faunuloides it ends midway between the first and second median 

 nervules ; on the underside of the forewing the black discal bands are 

 highly lunulated, and the points of the lunules almost meet in 

 M. faunula^ while in M. faunuloides the bands are nearly straight, and 

 the inner one is only slightly lunulated ; this character is even more 

 strongly pronounced on the hindwing, as in M. faunula anterior to 

 the third median nervule these bands entirely join, enclosing two large 

 oval spots of the ground-colour ; lastly, the yellow colour is much 

 duller and does not extend half as far on to the disc in 

 M. faunuloides. 



Described from two specimens kindly given to me by Oapt. E. Y. 

 Watson, which were captured in June, 1893, at Number Three Stockade, 

 in the North Chin Hills, at 3,500 feet elevation above the sea.

Habitat : Battak Mountains, N.-E. Sumatra. 



Expanse : $, 1*6 ; $ , 1*8 inches. 



Description : Male. Upperside, both wings deep velvety- black. 

 Forewing with three subapical white dots placed one above the other, the 

 middle one rather nearer to the base of the wing than the other two ; 

 a short oblique shining ferruginous fascia is placed outwardly against 

 the three dots. Hindwing with the abdominal margin broadly pale. 

 Underside, both wings pale dull brown ; a common discal narrow 

 macular violet-whitish fascia, in the forewing commencing at the sub- 

 costal nervure, where it is narrowest, ending on the submedian nervure, 

 where it is broadest, the fascia outwardly bowed, its inner edge
