the white subapical band on the forewing less than one half as wide; beneath it resembles damcisippe Fldr. 
from New Guinea. But the ?? approximate those of cleanthis, being distinguished by the somewhat broader, 
white subapical band on the forewing, the lighter, nearly black-green ground-colour and their smaller size. Thus 
whereas the cf is intermediate between insulata Btlr. and damcisippe Fldr ., the ? represents a transition from 
woodlarkiana to cleanthis. Fergusson, d’Entrecasteaux Islands. — woodlarkiana Fruhst. named from the island 
which is its home, is inferior in size to my smallest damasippe- cfcf ; from which it can only be told by the 
narrower, black, blue-iridescent outer border on the hindwing, and the less broad, white, subapical band on the 
forewing. On the under surface the hind wing is marked with a green discal band, not found in damasippe, 
and with a continuous row of irregulary arranged black dots and streaks, such as they are always found in 
the Australian form chrysippe F., whereas in the Papuan Cethosias they appear distinct only at the anal angle, 
being hut faintly indicated or disappearing altogether toward the middle and the costal margin. Also the double, 
basal row of elongate black spots is separated in woodlarkiana by a green band which, added to the light 
violet-gray bordering of the black submarginal ocelli, gives the entire under surface a brighter and more gaily- 
coloured appearance. Still greater is the difference in the ??, which deviate from the invariably red-brown ?? 
of damasippe in having the basal half of both wings brown-green, changing to yellowish at the median vein of 
the forewing and being thinly sprinkled with dark red on the hind wings. Wherever the brown-green shades 
into the black colour of the outer half, it displays in reflected light a dark steel-blue iridescence. The black 
marginal border encloses a continuous series of distinct, green-gray, sickle-shaped spots, not found at all or but 
faintly indicated in damasippe. The hindwing has on the under surface the basal and discal bands broader and 
more distinct than in cf, and of a dark moss-green colour. In another ? which has the basal area not dark red 
on either wing but only bordered all around with violet, the dainty appearance is still increased by a submarginal 
row of 7 white spots, enclosed within the black outer border, and of which the three uppermost are sagittate, the 
four lowest ones helmet-shaped. — cenchrites Fruhst. approaches in size woodlarkiana Fruhst. from which it 
differs in the following way: The fore wings have the white subapical bands somewhat broader, the submarginal 
row of whitish lunules reduced; the hindwings are much more broadly bordered with black, showing but a 
trace of the continuous band of lunules distinguishing woodlarkiana. On the under surface the forewings are 
more distinctly marked with white, and the black median band is distally more profusely adorned with metallic 
green-blue dashes. Came from some unnamed islands adjacent to British New Guinea. 
C. obscura replaces cydippe in the Bismarck Archipelago; next to C. leschenault it shows the plainest 
markings in the entire genus. The upper surface is black, in cf with more or less intense blue iridescence, in 
the ? without any lustre, so that even fresh specimens have a worn appearance. On the forewing we meet the 
characteristics of C. cydippe in the red segmentary patch in the submedian area, and again on the hindwing 
of the cf which resembles in the basal half the ? of cydippe , but is beneath paler, uniform gray-brown, without 
any red whatever. The pointed terminal arches or crescents found in all Cethosias are lacking, but on the 
other hand the submarginal band is especially strongly developed, varying in width according to the locality. 
obscura inhabits the woods along the shore of the Bismarck Archipelago, and is not so abundant as it Papuan 
allies. — obscura Guer. (llOe), so far only known from Neu-Mecklenburg and Nussa Laut, has in the ? the 
upper surface pale black-brown, suffused with a faint blue lustre The submarginal spots are either chalky- 
white or yellowish. On the hindwings the basal red is reduced to a few ray-like streaks, disappearing in the ? 
entirely. Beneath the submarginal macular band is considerably broader than above, in the cf dirty white and 
quite distinct, in ? yellowish, blurred and faded. — antippe Sm. is a lovely, distinct, insular race with brillant 
white, nearly twice as broad, submarginal spots on the upper surface which reflects an intense, dark blue-violet 
iridescence. The under surface has also on the hindwing the basal half broadly yellowish-red, shading into 
aniline-red at the periphery and resembling somewhat the red upper surface of C. myrina. The ? has never 
been described, the figure which Smith gives of the ? really representing the cf. Analogous to obscura, it 
probably deviates from the cf in the diminished, if not wholly obliterated, red basal colouring on the under 
surface of the hindwings. Neu-Pommern, Neu-Lauenburg. The form found in Neu-Hannover differs but 
slightly from antippe. - gabrielis Bothsch. from St. Gabriel, Admiralty Islands, unknown to me in natura. 
C. gabrielis Bothsch. resembles obscura Guer., but has on the upper surface the white spots on the fore 
wings quite small, nearly all round, the upper ones occasionally subtriangular, 1 1 / 3 —2 mm in diameter. On 
the hindwings the spots are more than twice the length of those on the forewings, oval and nearly all of 
equal size excepting the last one, which is broader and notched in the middle, and placed farther from the 
outer margin than in obscura. On the hindwings the costal region is in cf without any orange-red spots, the 
colour of the under surface a deep black-blue. St. Gabriel, Admiralty Islands, collected in February 1897. 
Tribus Argynnidi. 
14. Genus: Melitaea F. (Vol. 1, p. 211). 
This genus closely approaches Argynnis in those species which have been separated from it as Brenthis , 
and it is not easy to distinguish the two in the imago. Probably the surest way to discriminate between
