NTMPHALINyE. (Sronp potamina.) 23 



white spot, the middle portion being slender, its lower portion broad, and joined to 

 a short streak at the posterior angle. Hindwing crossed by a broad fulvous upper 

 discal band extending from below the base to near the apex, and a lower diseal band, 

 both being partly united before the apex, the latter band bearing a small black- 

 speckled spot between the middle and lower medians, followed by a slender lower 

 submarginal line which extends from the anal angle only to the upper median veinlet, 

 where it curves upward and joins the lower discal band, and beyond by a slender 

 marginal line extending to the apex ; the abdominal margin pale duller fulvous. 

 Underside dusky olivescent brownish-fulvous, paler externally ; with similar disposed 

 markings of the upperside, but much less defined, especially on the hindwing, and 

 all suffused with chalybeate lilacine-white. Foreioing also with a white streak within 

 upper base of the cell, a rounded upper subapical spot and a more prominent lower 

 subapical streak, a small blackish outer patch between the lower medians, and 

 another patch beneath it. Hindwing crossed by a slender dark fulvous inner discal 

 sinuous line, before which is a small dark fulvous spot within the cell ; a small 

 white spot inwardly edged with black scales between the middle and lower medians. 

 Body and palpi above fulvescent-brown, white beneath ; legs above fulvous, white 

 beneath ; antennae black, club tipt with fulvous. 



Female. Upperside dark fulvescent-brown ; markings as on upperside, but 

 somewhat narrower, and of a much paler fulvous-yellow. Underside also fulvescent- 

 brown, all the markings as in the male, but paler and more conspicuously defined.

Habitat. — Sikkim ; Bhotan, Assam ; Khasia Hills, Upper Burma. 



DisTEiBUTiON. — "We possess specimens from Nepal taken by the late General Gr. 

 Kamsay ; from Sikkim and Bhotan, taken by Mr. G. C. Dudgeon; and from Assam. 

 " It is not an uncommon species in Sikkim, where I have taken it in October at low 

 elevations, between 3000 and 4000 feet. It has the habit, when disturbed, of settling 

 head downwards with closed wings on the trunk of a tree, in which position it is 

 particularly difficult to catch with a butterfly net. Like many other butterflies of 

 this Sub-family, it is very fond of over-ripe fruit " (de Niceville, Sikkim Gazetteer, 

 1894, 135). Mr. H. J. Elwes (Tr. Ent. Soc. 1888, 341) says it is "not common in 

 Sikkim at 3000 to 4000 feet during and after the rains. A specimen from the East 

 side of the Tista, taken in March, is much smaller and paler in colour." Major 

 C. H. B. Adamson (List Butt, of Burma, 13) records it (and we have identified 

 specimens as being this species) as " not uncommon near Bhamo, Upper Burma, 

 where it settles with closed wings on the trunks of trees in shady places, in Sep- 

 tember and October." Dr. N. Manders, in his Notes on the Lepidoptera of the 

 Shan States (Tr. Ent. Soc. 1890, 521) records " one specimen taken at Fort Stedman 

 in August."
