with a silvery cloud, from which a faint ferruginous line runs across the wings nearly to tlie 
anal angle, touching a spot in place of the rounded spot of the upper surface, but of a paler 
colour. Legs nearly white. 
" This species may be known from Gonepteryx verhuellii by its rounded posterior wings, and from 
Gon. lycorias by the large spot of the anterior wings and other characters." {Doiihleday, I. c.) 
Female {urania, Butler). " Upperside : front wings pale yellow, deeper at the outer margin ; 
anterior margin much curved, and ending at its outer extremity in a sharp, uncated apical 
point ; outer margin slightly sinuated on its upper edge ; apex brown, deeply sinuated and 
dentated ; a large, perfectly circular, deep-brown spot between the first and second sub- 
median nervules. Posterior wings somewhat quadi'atc, pale yellow, deeper at the outer 
margin. 
"Underside: front wings dirty yellow, paler on the inner margin; discoidal cell irrorafed with 
brick-red : a small irregular silver spot surrounded with red in the middle of the end of the 
cell, with a minute vertical lunula just above it ; the costal and subcostal nervures ending in 
small red spots ; a somewhat triangular silver dash on the anterior margin, close to the apex : a 
large ferruginous round spot, ending below in a tine oblique red line, between the first and second 
submedian nervules ; two small, longitudinal, oblong, pale brown spots placed obliquely between 
it and the silver apical dash. Posterior wings dirty yellow ; cell irrorated with brick-red, a 
small irregular silver spot, surrounded with red, in the middle of the end of the cell, with a 
minute red lunule just above it ; a small brown lunule above the end of the cell, and halfway 
between it and the anterior margin ; a band of oblong pale brown spots crossing the wing 
between the nervules, and following the direction of the outer margin." {Bailer, I. c.) 
Although described as a distinct species urania is without doubt the female 
of D. waUichii. 
Chinese specimens of B. waUichii are rather larger than those from India. 
In the males the costa towards apex is marked A^ith red, and there is an 
oblique streak of the same colour, interrupted by the nervules, from the apical 
black patch. The under surface is identical with that of Indian specimens 
of the same sex. The females from both countries are alike. 
Fairly common throughout Central and Western China at moderate eleva- 
tions ; the female is scarcer than the male. 
Elwes (Trans. Ent. Soc. Lond. 1888, p. 415) refers to a specimen from the 
interior of Sikkim, but the species must be rare in that district, as there were 
no examples of it in the collection of the late Otto MoUer. It seems, 
however, to be plentiful in the Khasia Hills. 
In his ' Catalogue of Diurnal Lepidoptera ' Kirby (p. 489) gives China as 
a locality for 1). verhuellii, an allied species, but this was not observed in any 
part of the country visited by my collectors.
