152 HESPERIA. 



subcostal streak, another shorter one below this in the cell, two sub- 

 apical small spots separated from one another by the penultimate subcostal 

 branch, and an indistinct spot on the disc between the second and third 

 median nervules, opaque ochreous-brown. Underside, forewing greenish- 

 black, increasingly bordered in front from the base to the apical angle, 

 and thence decreasingly to the inner angle with ochreous-brown, varied 

 by light streaks on the folds and by the two subapical spots of the upper- 

 side. Hindwing throughout ochreous-brown similarly varied with lighter 

 streaks. Cilia smoky-brown in the forewing, paler on the hindwing. 



Expanse: 1^5 inches. 



One male, Irangmara [Cachar] , 8th July, another very old specimen, 

 also from Cachar, in the collection of the Indian Museum, Calcutta, and a 

 third taken in the Sikkim Tarai by Mr. Otto M oiler on I4th September, 

 1881. 



B. scptentriomtm is nearly allied to B. subditns, Moore, but it differs 

 therefrom in its considerably larger size, in the spots on the upperside of 

 the forewing being of a brighter ochreous, in the shade of the ochreous of 

 the underside generally, and in lacking the conspicuously-broad very 

 pale yellow discal streak which extends from the base to near the outer 

 margin of the hindwing and forms so marked a feature both in B. subditus 

 from the Nilgiri and Pulni Hills and in B. vittatns (Felder) from Ceylon." 

 (Wood-Mason and de Nicevillf, I. c.). 



Also recorded from the Nilgiris (H amp son). 



I have a single specimen of this species from Beeling, Upper Tenas- 

 serim. 



In collections Indian Museum and de Niceville.
