270 LEPIDOPTEEA INDICA. 



wliite. Cilia of both wings white, with a black base, the white tipped with black from 

 the tail to the anal ansrle. Underside as in the male. 



Expanse of wings, $ ^ 1t*o" to 1^^ inches. 



Habitat. — North- West Himalayas. 



Distribution. — Eecorded by de Niceville from Pyura and Eamgarh, 4,000 to 

 7,000 feet elevation, by Doherty from Kumaon, by Mackinnon and de Niceville from 

 Mussuri, where they say it was exceedingly common, double brooded, the first from 

 May to July, the second in September. The earlier brood is found in shady, woody 

 ravines only, the latter brood on the tops of hills. They say Mrs. Robson has bred it 

 at Mussuri in May. The larva feeds on Rhododendron arharum. We have it from 

 Simla, the types are labelled Western Himalayas ; it is in the B. M. also from Ranikhet 

 and Bhagi. The larva and pupa, though figured, have not been described.

Imago. — Male. Upperside, both wings rich metallic green, with a marginal black 

 border. Forewivg has the black border narrow, of even width throughout, the apical 

 half of the costal margin also very narrowly black. Ilindwing with the costal margin 

 broadly black, the black border to the outer margin of moderate width, twice as broad 

 as in the forewing. Ciha black ; tail black, tipped with white. Underside, both 

 wings pale fawn colour, glossed with silvery. Forewing with an outer discal 

 slightly curved white band, attenuated posteriorly, extending from the costa to the 

 first median nervule, inwardly bordered with fuscous ; a broad sub-marginal fuscous 

 band, anteriorly faint, terminating at the sub-median nervure, in two dark spots, 

 narrowly margined throughout its length with white ; a marginal white line followed 

 by a fine blackish anteciliary line ; the discocellular nervule faintly marked with 

 fuscous. Hindwing, a broad white discal band from the costa to the first median 

 nervule passing beyond the discoidal cell, inwardly margined with fuscous, and 

 continued to the abdominal margin in a broken V-shaped line ; a double row of 

 sub-marginal white spots, outwardly concave, the outer row conspicuously, the inner 

 row obsoletely, followed by a black-centred spot at the extreme anal angle, inwardly 

 marked with yellow, which is continued narrowly up the abdominal margin ; a marginal 

 white line, followed by an anteciliary black line, the discocellular nervules faintly 

 marked with fuscous. Abdomen dark, paler beneath ; thorax densely clothed with 

 greenish-white and pure white hairs above and below respectively. 



Mr. de Niceville has kindly compared the type with its nearest allies and writes to 

 me as follows : — Appears to be most allied to Z. syla, Kollar, and Z. birupa, Moore, from
