forewing as far as the middle median, but its distal border is reduced to small, comma-shaped streaks. On the 
hindwing the submarginal band is in cf absent, in ? almost obsolete. The under surface has on the hindwings 
some olive-green subterminal stripes and the liver-spots margined with dark gray-violet. Larva as above 
described, discovered by H. Kuehn. cydalima Fldr. has on the upper surface the most pure and prominent, 
white subterminal band and at the same time the narrowest black proximal border flanking the spot on the f. w. 
On the hindwings which are more variegated than in theona , the blue iridescent marginal area is interrupted 
by red-brown cuneiform spots. The under surface has the white markings on the forewings confluent, the 
hindwings are of a faded, “washed-out” brown and traversed by a gray-green-margined median band. Larva

cyrene Wall, is one of the most beautiful butterflies in the Papuan Region, differing from all known forms of 
cydippe in that the white band on the hindwing proximally surrounds the black patches usually found in the 
Cethosias, and gradually shades into the submarginal area which, especially in the ?, is over a narrow space 
reddish, and finally black. On the forewing the white area is considerably narrower than in insulata, but 
likewise prolonged to the middle median; the basal area is paler red-brown than in theona. On the under 
surface of the hindwing the white submarginal zone is separated from the conspicuous subterminal lunules only 
by a narrow gray stripe; otherwise the hindwings are as in insulata. Scarce, island of Waigeu. — damasippe 
Fldr. was based by the author upon specimens brought to Europe by the Aetna Expedition and stated to 
come from the “Litus occidentale” of New Guinea. According to Felder damasippe occurs also in Dorey and 
Mysol, but not in “Aru”. From the 54 specimens contained in my collection it appears that in New Guinea 
there are found beside damasippe three other local forms, namely: 
a) one in north-western Dutch New Guinea, 
b) one in south-western Dutch New Guinea, 
c) one in German and British New Guinea. 
To the first l refer 14 specimens from Dorey and the Arfak Mountains, distinguished by having on the 
forewings the whitish, subapical, transverse band very narrow and often quite indistinct, the black distal border 
on both wings very broad and the upper surface dark brown-red at the base, b) is represented by 6 cfcf- 
specimens from Kapaur collected by W. Doherty, and 1 ? from Kajumera Bay, in which the transverse band 
is brillant pure white, 9—10 mm in breadth, and the basal area on both wings pale reddish. From Felder’s 
description it does not appear whether his diagnosis refers to a or b, wherefore I reserve for the hitherto 
unnamed form the name claudilla Fruhst. (111b?); — the form from German and British New Guinea I call 
praestabilis Fruhst. (Ill a, b); it deviates from b in having on the forewings the white band somewhat narrower, 
only 6—7 mm wide, and the under surface more richly marked with white; altogether it approaches more the 
Australian chrysippe F. But in no case is the transverse band on the forewing so much reduced as in specimens 
from Dorey. In all three New Guinean forms we find ?? with red-brown upper surface (claudilla Fruhst.) 
and ?? having the basal area quite pale brown, yellowish-green or even blue-green. The latter is ?-forma 
hermanni Fruhst. (111a erroneously called damasippe). Larva resembles that of insulata, black with yellow 
rings, described in the general diagnosis, praestabilis is found on Astrolabe Bay and the Gulf of Huon in 
Kaiser-Wilhelmsland. Specimens from British New Guinea differ from praestabilis only in having on the upper 
surface the black marginal area broader and suffused by a blue iridescence, and the submarginal patches on 
the under surface of the hindwings less distinctly ringed with white-violet, approaching in this the local form 
from Kapaur in south-western Dutch New Guinea. The ? which lately was found also on Yule Island, differs 
from hermanni -? (Ilia) in having on the forewing the white band narrower and the basal region greenish- 
yellow. — lucina Fruhst. is inferior in size to the forms from the main island; the cf has, considering its 
small size, the macular band on the forewing very broad, and its proximal border broadly suffused with a 
bright blue iridescence. The ? resembles the ? of claudilla, but is still deeper red-brown at the base and 
has the transverse band more compact. Island Jobi. In Mafor we find a form with rather darker under surface. 
— chrysippe F. approaches in cf praestabilis, but the ? has the upper surface lighter red-brown and on the 
hindwing the usual Cethosia- spots more translucent. On the under surface the hindwings are, especially toward 
the outer margin, lighter brown, in ? gray-brown. Queensland. — As imperialis Btlr. a form has been described 
from Cape York, northern Australia, closely allied to chrysippe, but with richer blue iridescence. Not represented 
in my coll. — cleanthis Fruhst. in cf closely approaches damasippe from New Guinea, but has on the forewings 
a narrower white subapical band and larger white submarginal dots. The hindwings have a distinct row of 
yellow submarginal spots, resembling cydippe woodlarhiana Fruhst. The under surface is somewhat less gaudily 
coloured than in woodlarhiana, but possesses also the green discal and basal bands characteristic of the latter. 
The ? differs from that of damasippe in having on both wings the basal area gray-green instead of brown-red, 
and in the very distinct submarginal row of whitish, elongate spots, and a series of very delicate, white mar¬ 
ginal lunules; the forewing has the band very narrow as in the cf. The ? of cleanthis is larger than that of 
woodlarhiana and shares with it the dusky colouring, but lacks the orange irroration that gives the latter such a 
lovely appearance. Kiriwina, Trobiand Islands. — alkmene Fruhst. The cf approaches in the dark red colouring 
of the base of the forewing and in the bordering of both wings C. insulata Btlr. from the Key Islands, but has
