marginal band composed of oval rings, close in front of the border a white line being interrupted at the veins. 
Marginal scales black with white points. $ above with a broad white band and lustrous-blue scales at the base 
of both wings, a blue, submarginal, arcuate line in the hindwing distinct, in the forewing only indicated on the 
posterior part. Under surface like in the only the rings of the blue marginal band in the hindwing somewhat 
smaller and more distinctly separated. Ceram, Amboina.

cellular spot. The black marginal part and the basal band on the under surface of the hindwing broader, therefore 
the white band narrower than in the closely allied cyanea\ also the blue marginal band broader and more homo¬ 
geneous, the black spots comparatively smaller. North Australia.

narrow black border, the costal margin of the hindwing white. Under surface in the forewing broadly bordered 
with black, the whole middle and inner-marginal part white, at the anal angle an indistinctly interrupted, 
whitish marginal line; liindwings beside the white median band with a white costal margin, the bluish-green 
marginal band rather narrow with small, circular spots, distally accompanied by a white marginal line. $ above 
very much like the $ of cyanea, the white band of the forewing at its apex less sharply angled, the black border 
broader; costal margin of the hindwing broadly greyish-black, the blue submarginal macular series more 
distinctly prominent. On the under surface the double white marginal line in the forewing, particularly the 
distal one, less distinct and reaching less far anteriorly, the black costal-marginal band in the hindwing is 
broader and longer, the marginal part is more broadly coloured in black, the spots of the marginal band are 
smaller. New Britain and New Ireland; Bismarck Archipelago, New Lauenburg and New Pomerania. — Prom 
the Bismarcp Archipelago 2 special forms are described: var. pseudochrotnia Ribbe (142 e) from New Pomerania, v&ei alochro-

surface also the costal margin is bordered with black and on the under surface the black costal-marginal border 
is confluent with the black marginal half. —- ab. intermedius Ribbe, from New Lauenburg and New Pomerania, intermedins. 
differs from the typical form in the hindwing by the steep, black costal-marginal band being obtuse at the 
end, whereby it resembles smaragdus (143 h). 
Th. rosselana B.-Bak? Allied to hamilcar (142 d). <$ above dark violettish-blue, narrowly bordered rosselana. 
with black, the white band beneath slightly showing through above, hindwing with a broad white costal margin. 
On the forewing beneath the blackish-brown costal margin is very broad, extending as far as the middle of 
the cell, the posterior marginal part as far as vein 3 likewise broadly darkened, also the white submarginal line 
extending to vein 3; the light-blue marginal band in the hindwing very broad, particularly at the anal margin, 
anteriorly narrowed, the black spots at the anal margin indistinct; the fine white marginal line as in the 
allied species. Louisiads (Rossel Island). 
Th. epicoritus Bsd. (143 f). <$: The black border above narrower than in cyanea, the black beneath epicoritus. 
still more developed than in arinia (143 h); in the forewing the white band, in the middle of the distal margin, 
almost reaches the border, a single white marginal line is indicated only on the inner-marginal part. In the 
hindwing the black marginal part covers more than half the wing, the white band is narrow, the marginal band 
broad, the white marginal line very fine. In the $ the white band recedes greatly also above, the bases of the 
wings are scaled in a lustrous blue. -On the under surface the black colouring is still more extensive than in 
the (L the marginal band in the hindwing broader. New Guinea. Waigiu.

an indistinct white spot. The black colouring beneath somewhat less extensive than in arinia, the marginal 
band in the hindwing narrower. Also in the wing-contour both species are different, the forewings are more 
pointed than in arinia, the border is less curved. $ with the same differences as the <$. Island of Wetter, Key 
Islands.

of a white spot; beneath, the white band extends in its full expanse as far as close in front of the border, only 
at the anal angle between veins 1 and 2 enclosing yet a black streak. The white band of the hindwing narrow, 
marginal band broad. New Guinea, Waigiu, Mysore, Soron, Salawati. 
Th. pindus Fldr. (142 e). Differs from sperchius (143 i) by the broader black border of the wings above pindus. 
and the smaller extent of the white band beneath; the black border of the forewing very broad, the two white 
marginal lines distinct. The black costal-margirial band in the hindwing fused with the marginal part, the 
marginal band narrow, composed of isolated rings, and only developed on the posterior half of the wing. $ above
