with light, the small postmedian costal band of the hindwing being particularly prominently dark. The difference 
of the sexes above is to be seen from our figures. The species is distributed over the whole Australian continent. 
In the south-east the insects are paler and beneath more reddish than those from Queensland. — In ab. atrofusa 
Waterh. the basal half beneath is suffused with dark, and in ab. albocincta Water hi the hindwings are more 
broadly margined with white. — eremicola Bob., the form from Flores, is above lighter blue than Australian 
continental specimens, the anal spots bordered with a purer white; it also occurs inAlor. — arnoldi Fruhst. from 
the Bismarck Archipelago shows the anterior band of spots at the end of the basal third of the hindwing beneath 
extending through the whole width of the wing and also continued through the whole hindwing. Upper surface of 
the o reddish dark brown, with a bright blue lustre as far as towards the margin. Both sexes similarly coloured, 
only distinguished by the shape of the wings. — This Australian species is in some places rather common. 
N. scintillata Luc. is also Australian and flies in Queensland in the District of Cairns and on the 
Richmond River. It somewhat resembles palmyra, but differs from the allies by the forewing showing, like 
in thadmor (152 k), a white discal spot. Apparently not common. 
N. keiria Drc. This species is Papuan. Typical keiria originate from the Salomons and are in the 
£ above lavender-blue, in the $ greyish-brown; beneath light bluish-grey, the submarginal chain of spots very 
much torn, the marginal eyespots very distinct; the subbasal eyespot is a small spot conspicuous by its black 
colour, not by its size or colouring, and proximally tinted yellowish-red. Aola; Quadalcanar, Malaita, Florida. 
— kokopana Ribbe come from the Bismarck Archipelago and differ so little that they were probably combined 
by P agensteoher with the astarte which he states to have been captured by Ribbe in New Pomerania and 
New Lauenburg. -—- nebulosa Drc. from the New Hebrids entirely resembles above the typical keiria and only 
differs beneath by the absence of the subanal eyespot. 
N. berenice H.-Schdff. Likewise described from the Australian region, from the District of Cairns 
and Rockhampton. $ above violettish-brown; $ with a blue disc of the wings, smaller than New Guinea speci¬ 
mens (these = tristis Bothsch., with very narrow and dull lines beneath). In the $ of berenice these light lines, 
according to Waterhouse, are more distinct, the size of the $$ varies between 12 and 15 cm. — As Fruh- 
storfer thinks to be able to prove by the anatomy, there belong to this species numerous, hitherto separated 
forms distributed over a great part of the Indian region. Thus plumbeomicans Marsh. &• Nic. inhabits the Mergui 
Archipelago and Chittagong. It somewhat resembles macrophthalma, but it has 3 instead of 2 transverse bands 
on the forewing beneath. — nicobaricus Marsh, dfc Nic. has beneath both wings violet slate-coloured, the mar¬ 
ginal and submarginal bands of spots more distinct, iron-grey, narrower and separated farther from the discal 
band by a wide area of the ground-colour; all the bands more distinct, the subanal eyespot more brightly 
surrounded with orange-red. From Kamorta and Catchall in the Nicobars where the form is apparently rare. 
—- aphya Fruhst. comes from the rice-port of Rangun in Siam. Smaller than plumbeonitens from India, wings 
above with a blue reflection without violet ; this blue penetrates farther towards the margin than in icena (152 h) 
from Sumatra. Also the under surface is similar to that of icena, but the white lines are still finer and more 
delicate. —- ceylonica Fruhst. differs from Indian specimens and those of the Nicobars by rounder wings and the 
bands beneath showing through more distinctly. Beneath the blackish transverse bands are bordered with 
a pure white, like perusia. Ceylon. -—- icena Fruhst. Fldr. (= beroe Dist. nec 152 h) is the form flying in Borneo 
and Sumatra. $ darker than Indians, but lighter than nicobaricus and with a brighter lustre. $ with a much 
broader marginal black. — The specimens are much smaller than those of most of the other forms. -— aphana 
Fruhst. Above pale violet, beneath of a very light ground-colour. The submarginal spots smaller than in icena. 
Nias. — isana Fruhst. is the Javanese form. Much lighter than icena; under surface lighter grey. —- rapara 
Fruhst. is very much darkened, with a sooty smoky-brown upper surface. Also beneath the dark submarginal 
spots of both wings are deep dark brown. Bawean. - — ■ zyrthis Fruhst. $ above much darker violettish-blue 
than isana and icena. Under surface still lighter than in the latter; $ smaller, the blue lustre of the hindwing 
a little more extensive, the submarginal lunae of a purer white. Lesser Sunda Islands. — eliana Fruhst., 
from Celebes, is larger than the other forms of berenice, with a broader black distal-marginal band on the forewing 
and hindwing. Under surface coloured brighter, with more prominent black spots and more distinctly defined 
white longitudinal bands. In the $ the marginal black is spread almost across the whole upper surface of the 
wing, only behind the cell of the forewing there is a diffuse bluish stripe. Celebes. -— zygida Fruhst. (154 d) 
from the Philippines is a little smaller, above lighter bluish-violet and beneath not so brightly marked. — illuen¬ 
sis Rob. has an expanse of but 24 to 26 mm; the <$ is above greyish-blue ,,with or without a lustre“. Margin 
very narrow dark; under surface ashy-grey or greyish-brown, the transverse bands little darker, but bordered 
with light, the subanal eyespot rather large, surrounded with yellow; $ above with 1 white line at the margin 
and 2such antemarginal lines, the latter composed of small whitish crescents; Aru Islands, probably also Southern 
Moluccas. — major Rothsch. is a similarly coloured, but larger form belonging hereto, from Ceram. — carnania 
Fruhst. is likewise larger, the under surface more brownish-grey; the $ in a dark rainy season form with a deep 
blue, brightly lustrous basal area of both wings, confined, however, by a broad black border; besides in a 
lighter form very much resembling the pavana- $ $ from Java and Sumatra and being above light blue with 
a narrow black margin. From Obi and Halmaheira. — dobbensis Bob. (154 c!) shows the $ above light blue 
with a violet reflection and a greyish-brown margin; still smaller than the preceding form. $ above dark greyish
