spot below this again in the first median interspace. Mindwing black, more or less 
streaked with blue between the veins. UNDERSIDE, doth wings like the male, but the orange 
spots at the anal angle of the Aizdwing of the male a deeper colour in the female. 
‘* This species varies considerably in size, in the breadth of the brown margin on the 
upperside, and in the colour and position of the bands on the underside.” (Hewitson, 1. c.) 
This isa widely-distributed species in the Himalayas, occurring on the outer ranges from 
Murree to Sikkim at any rate. I have always taken it flying about low oak-trees; Colonel 
Lang writes of it ‘Observed in a richly-wooded North-West Himalayan glen, flitting up and 
down the stream, pitching on moist rocks or pieces of wood in mid-stream.” Also “ Rare 
in Kumaon, taken in June at the top of Cheena, Naini Tal, 8,600 feet.’’ In Sikkim it 
appears tobe rare. Mr. Otto Moller possesses two pairs only,

DESCRIPTION : “ MALE. UPPERSIDE, doth wings metallic green, broadly margined with 
brown. UNDERSIDE, doth wings greyish fawn-colour, with a transverse pale-bordered brown 
disco-cellular streak, a straight discal and a lunular submarginal band, the discal band on the 
Jorewing short, the discal band on the Aindwing straight till where it reaches the sinuous angle, 
two anal black-centred bright orange spots. C7/ia whitish. FEMALE. UPPERSIDE, loth wings 
dark brown. forewing slightly tinged with blue at the base, two subapical bluish-white 
spots.” UNDERSIDE, doth wings as in the male. 
“ Distinguished from D.[=Z.] ziha, Hewitson (of which, at present, I know only the 
female), in the underside being differently-coloured, the submarginal band on the forewing 
being uniform in colour and without the terminal spots, and in the discal transverse band on 
the hindwing being quite straight to where the sinuous portion turns off to the abdominal 
margin.” (JZoore, 1. c.) 
Z. birupa is usually a smaller species than Z. sy/a, Kollar, the male on the upperside of 
the forewing has the outer black marginal band broader and more curved ; the female has much 
less blue on the upperside ; the colour of the ground on the underside is quite different, being 
greyish fawn-colour in both sexes in Z. dirupa, silvery greenish-whitish in Z. sy/a. 
I have taken this species somewhat commonly at Simla about midsummer flying round 
small oaks, Colonel Lang has met with it at Masuri in June and July at 7,000 feet, and 
Mr. Doherty reports it from the outer ranges of Kumaon. It appears to be a rarer species 
than Z. sy/a, with a more restricted range.
