the himhuing, and continued less prominently on to the disc of the /ore~oino ; in some specimens 

 they are obsolete. It most nearly resembles E. Uticocyma, but differs in having the wings 

 shorter and broader ; on the upperside the discal series of purple spots on the foreiving far 

 more elongate, the inner series absent; and on the hindidng in the presence of the white 

 submarginal spots : and on the underside it has white submarginal spots and the outer mar- 

 gin only variegated, whereas E. Uucocyma has no white spots, and almost the entire under- 

 surface variegated with pale strire. 



It is not a common species, and we have as yet only seen it from Sikkim, Cachar and Syl- 

 het. Mr. de Niceville took it in the valley of the Great Runjit, Sikkim, in October ; and 

 Mr. Wood-Mason took a single specimen on Nemotha, Cachar, in vSeptember. It most pro- 

 bably mimics Euplxa (Stictopl<xa) kopei, which Mr. de Niceville has taken in Sikkim at the 

 same time and in the same locality.

Habitat : Sikkim, Upper Tenasserim. 



Expanse : 275 to 3*20 inches. 



Description : " Male : Upperside, fomobig black, glossed with .slaty-blue ; costal 

 margin with small bluish-white dots ; longitudinal spots in the middle of the wing, and spots 

 from near the apex to the posterior angle bluish-white. Himkoing, from the abdominal margin 

 to the middle of the wing, white ; anterior and posterior border black, the latter with some 

 marginal white spots. Underside white, nervures black. Fonrcoitig covered throughout with 

 deep black stride [or as Wallace describes it, black, irregularly blotched and irrorated with 

 white]. Hindwitig with the exterior margin covered with deep black strire ; the base of the 

 wing black, with numerous small white spots, and a large red spot below the cell ; abdominal 

 margin broadly suffused with yellow." {Moore, 1. c.) " Female: Upperside paler, with the 

 bluish and white portions more diffused. Underside very much whiter, with finer irrorations, 

 and the yellow patch more diffused." {]VaUace,\. c.) The secondary sexual characters of the 

 male differ from those of all other Indian species of the subfamily, as not only are the usual 

 tufts of hair on the upperside of the hindvving present, but the inner margin of the forewing is 

 folded upwards, and encloses a tuft of long ochreous-brown probably erectile hairs.

D. vasudeva is not very common, but will probably be found in all the hill ranges between 



Sikkim and Tenasserim.
