unnoticed local form from the Omi Shan, which, like sanaca Moore and perspicua m., is characterised by a pure 
white cell and much widened discal stripes on the hindwing. The yellow stripes of the under surface similar to 
those of adelma, but with white edges. Larva on Loranthus. Pupa elongate, brown with black spots and white 
tip. Head with two-pointed process, sides with short, but pointed spines. — chrysorrhoea VoJI. (56 d) is the 
only island race yet known, nearest to perspicua, without white cell on the hindwing and habitually very small. 
Pare on the highlands of Sumatra at elevations of 4—6000 ft. 
d. Hindwing with thin, long, yellow basal streak. 
D. albertisi Oberth. (= discus Horn. §) is among the most notable species, which always occur singly, albertisi. 
Oberthur’s cj-type has the upperside of the forewing entirely blackened, with only 5 small yellow submarginal 
spots. The proximal part of the hindwing above is yellowish, the distal part black-brown. On the under surface 
a large transcellular black spot is noticeable. Dutch New Guinea. — neyi Bibbe (54 b) represents the local race neyi. 
from British New Guinea, above with the exception of the apical spot completely white and beneath without 
the black median spot on the hindwing. The $ is still unknown. 
D. niepelti Bibbe. above white with broad, black distal margin. Porewing in the with 5 obliquely niepelti. 
placed white subapical patches, which are yellow in the $ above throughout chrome-yellow, anal half of 
the hindwing with greenish tinge. The under surface alike in both sexes, base and subapical spots of the forewing 
orange-yellow, all the rest black. Hindwing with peculiar fine gre^y-yellow submarginal lines, from which 7 
delicate grey stripes run out to the terminal margin. British New Guinea. 
D. meeki B. & J. Somewhat smaller than the preceding, above very similar, but the under surface meeki. 
of the with paler yellowy more sharply defined basal part to the forewing and the hindwing with a large, triangular, 
pure white costal spot. The $ has likewise straighter black distal margins and the white costal spot on the under 
surface of the hindwing is oblong. British New Guinea. 
D. callima B. & J. (56 e), which is here figured for the first time, is above white with uniform, moderately callima. 
broad, black distal margin to both wings. $ different, has the upper surface black with yellowish green basal 
part to both wings and a chrome-yellow median band in the disc of the forewing. Beneath this band is somewdrat 
broader. The under surface of the hindwing as in the the red submarginal band varying in extent, callima 
is very similar to bornemanni, from which, however, it differs in the white basal stripe. British New Guinea. 
D. blanca Fldr. has the rounded wings in common with battana, above throughout black-grey, with blanca. 
lighter central area on both wings and with very distinct whitish submarginal patches. Only 2 are known, 
from North Luzon. — apameia subsp. nov., of which only $$ are known, with the submarginal spots blue-grey apameia. 
instead of whitish and placed further from the distal margin. The yellow discal region of the hindwing is more 
extended in North Philippine specimens. Mindanao, Davao; discovered by Dr. Platen — nausicaa Fruhst. (54 f). nausicaa. 
The upper surface is very similar to the figured under surface, only on the hindwing the basal region is less sharply 
defined and somewhat lighter. The submarginal spots of both wings indistinct and the yellow region more restricted 
than in blanca. Very rare, only the one pair in coll. Fruhstoefer known, which Waterstradt found on the KinaBalu. 
e. Under surface of the hindwing with large, red, pointed basal spot. 
D. descombesi Bdv. (52 b). Described from Cochin China, where a darker race, particularly in the $, descombesi. 
occurs than the Himalayan subspecies which passes under this name. Moreover, the distal margin and the sub¬ 
marginal band of the Indo-Chinese descoynbesi are more broadly black, but the white submarginal spots of the 
forewing in the $$ much smaller, so that the descombesi-QQ approximate to eranfhos Fruhst. (52 c), from the eranlhos. 
Malay Peninsula, which is characterised by almost entirely black forewing with obsolescent white markings. — 
As leucacantha subsp. nov. the Sikkim race is here introduced, of which the figured dry-season-form (52 b) is leucacaniha. 
especially typical in the white instead of yellow marginal spots on the hindwing beneath and the much larger 
submarginal patches, especially also in the $$. There are three forms of the the one figured, with broadly 
white-grey veins on the forewing and light yellow upper surface to the hindwing; $-f. auriga form, nor., with auriga. 
almost black forewing with the veins very finely white, yellow submarginal spots and yellow hindwing; and §-f. 
leucogaea form, nov., with black forewing but white spots and reddish white upper surface to the hindwing. All leucogaea. 
three $-forms occur in Sikkim, the last also in Assam. The butterflies are common in the whole region, fly all 
the year round, in Siam in January in enormous numbers, and adorn even the parks in the large towns, such 
as Bangkok and Saigon, with their bright colours and the dazzling white of the upperside, floating slowly under¬ 
neath the shady trees in company with Delias hyparete ciris. Although natives of the plains they ascend in Burma 
to an altitude of 7000 ft. It is curious that the species does not occur on the large Sunda Islands; it is there 
replaced by belisama and eumolpe, but appears again quite unexpectedly on the lesser Sunda Islands. 
D. oraia Doh., from Sumbawa, Pura, $ above as descombesi, only with somewhat broader grey apex, oraia. 
The $ likewise resembles the £ of descombesi above, the cell of the hindwing is also dusted with black and the
