AAVst-Himalayan specimens are much whiter than the type, and the AYestern 
Chinese form is intermediate between the type and the black Central Chinese 
form. 
All forms of this species may be easily distinguished from tliose of D. bella- 
donna by the striated rather than round character of the pale markings of 
both surfaces and by the clubs of the antennae being white or whitish instead 
of black. 
Bisfrihution. North-western Himalayas, Simla, Kulu (Elwes), Central and 
Western China. 
Delias patrua. (Plates xxxvii. figs, i j , 2 ? , xxxv. fig. l, 
var. d .) 
Delias patrua, Leech, Entomologist, xxiii. p. 46 (1890). 
Male. Black. Costa, inner angle, discoidal cell, and nervular interspaces streaked with grey, the 
streaks in latter are attenuated towards outer margins, before which they unite with a whitish- 
centred grey spot, those nearest apex are linear, and the streaks preceding are not always 
well defined. Secondaries, inner area of the wings within submedian nervure, and a portion 
of interspace above canar3--yellow, each interspace above has a grey streak, those between the 
median nervules are centred with white, and the upper one is only separated from a broad 
disoal streak by the discocellular nervule ; a series of grey spots before the outer margin, 
those nearest anal angle with yellow linear centres. Under surface black : primaries with 
the streaks and spots as above, but white ; the costa is only sprinkled with grey scales ; there 
are two short yellow dashes between costa and submedian nervure towards apex, and the 
spots nearest apex are more or less yellow : secondaries have canary-yellow markings ; a 
broad patch at the base intersected by the proecostal ; a broad streak, whitish towards base, in 
the discoidal cell ; inner area as above ; a central and submarginal series of spots, but the 
former are only suffused with yellow to a greater or lesser extent. Fringes grey and 
black. 
Fanale. Fuliginous-black, the costa less grey, the streaks are shorter and are not connected with 
the spots towards outer margin ; the inner area above is whitish towards abdominal fold. 
Expanse, S 88 millim., 2 92 millim. 
Closely allied to I), belladonna, but at once separated by the -apparent 
absence of yellow patch at base of secondaries. There is a yellow dash on 
the costa of secondaries, but this is of small size, and it is always completely 
liidden by the inner margin of the primaries. 
Occurs at Chang-yang, Central China, in June and July. 
Var. lativitta, var. nov. (PI. XXXV. fig. 1, cJ .) Male. Black. Primaries streaked with 
white in the discoidal cell and each neri'ular interspace ; there is a broad white streak in the 
submedian interspace extending almost from the base of the wing to the outer margin ; this
