Th. plotinus Sm. & Ky. (143 g). The most closely allied to plateni, <$ above very narrowly bordered 
with black, hindwing with a white costal margin. Under surface essentially as in plateni-B, only the marginal 
band in the hindwing broader, with longer-stretched spots and without the distal white marginal line. $ above 
black-brown with some blue scales at the base of the wing and a rather narrow white band ending taperingly 
in the forewing. Under surface like in the <$, the indentation at the end of the white band of the forewing still 
more distinctly prominent. New Guinea (Stephansort); New Pomerania. -—- var. irregularis Ribbe (143 i) 
from New Pomerania is distinguished by a larger extent of the black colouring beneath; the black border of 
the forewing is much broader on the posterior half. 
Th. eudocia Dr. d? B.-Bak. (143 i). Allied to melius. $ above somewhat darker blue, the black 
border in both wings broader. On the under surface the black colouring is still more expanded, particularly 
on the costal marginal part of the forewing, the white band is still a little narrower and ends into a point in 
the forewing; the blue markings recede more. $ above almost black, the white band only quite narrow and 
feebly indicated, on the under surface prominent, though very narrow; otherwise beneath like in the Batjan. 
Th. ekeikei B.-Bak. Allied to eudocia H. H. Dr. (143 i). $ above with a narrower black border, the 
white band beneath diaphanous; the band itself somewhat broader, particularly in the hindwing, where it 
extends with its inner part more anteriorly and does not end taperingly but with a broad flat indentation; 
the ground-colouring more dark-brown than in eudocia, the metallic marking still more receding, thus the costal- 
marginal streak in the forewing and hindwing more feebly developed, the black spots of the marginal band 
proximally bordered with green semi-circles, distally with a blue arcuate line. British New Guinea (Ekeikei). 
Th. aryanus Gr.-Sm. ( = snelleni Sm. <b Ky.) (144 e). Allied to hymetus (142 d), the upper surface 
darker blue, the black border broader, though narrower than in piepersii. The black colouring beneath more 
extensive than in those two species, the blue-green costal-marginal stripe in the forewing extends beyond the 
centre, the black spots of the marginal band in the hindwing are broader and indented at the distal margin. 
The white band in the hindwing rather broad, in the forewing narrower and ending into a sharp point. In the 
$ the white band above is narrow, less extensive than in hymetus and piepersii- and does not extend in the 
forewing beyond the posterior cell-end, whereas in the hindwing it is very narrow and still less prominent; 
on the under surface it is broad and prominent, but likewise narrower than in the said species. Moluccas (Halma- 
heira, Ternate, Batjan). 
Th. piepersii Snell. (142 g). (Jr easily discernible from the allied species by the much broader black 
border of the upper surface of the wings and the blue marking beneath receding nearly altogether. The white band 
beneath broad and uniformly rounded off, in the place of the blue costal-marginal band in the forewing only 
a short, grey-white costal-marginal streak proceeding from the base. Marginal band in the hindwing vanished 
except some few narrow rings at the anal angle. Marginal scales unicolorously blackish-brown. $ above with 
an indistinctly defined white band, the grey-white costal-marginal streak in the forewing more distinctly pro¬ 
minent. Celebes. 
Th. hebes H. H. Dr. Allied to Th. piepersii (142 g), smaller, <$ above darker, more reddish blue 
and more broadly bordered with black, particularly at the anal margin of the hindwing. On the under surface 
the yellowish costal-marginal streak in the forewing is absent, and of the marginal band in the hindwing only 
the black spots are present; only the costal margin of the hindwing is sparsely scaled in blue as far as the centre. 
British New Guinea (Aroa River). 
Th. kruera H. H. Dr. upper surface rather dark blue with a moderately broad black border. 
Under surface white, the uniformly broad black costal-marginal border not interrupted by white or blue markings, 
in the black border of the hindwing a series of small blue spots. $ above with a broader black border, the centres 
of the wings likewise blue. Under surface like in the $. Salomon Islands. 
Th. nerine Sm. & Ky. (144 e). The only species known of the group, the hindwings of which are 
tailed at vein 2. <$: upper surface bright blue, lighter than in taygetus (142 d), distal margin of both wings very 
finely bordered with black; forewing in the centre indistinctly coloured in a whitish. Hindwing with a broad 
white band before the middle. The white, triangular inner-marginal area of the forewing beneath anteriorly 
extending as far as the centre of the wing, the band in the hindwing narrow, whitish-yellow, irregularly margined; 
markings greenish-blue, costal-marginal streak in the forewing extending as far as the centre, in the hindwing 
shorter, marginal band broad with large, irregularly shaped spots. Ron-Island (Geelvink-Bay, West New Guinea). 
e) cyanea-Group. 
The species ol this group are distinguished by exhibiting a black, white-pointed, small tail at the vein 2 of the hindwing; 
of the blue markings beneath they only have the well-developed marginal band of the hindwing. 
Th. cyanea Cr. (= cyanus F.) (143 h). upper surface dark greyish-blue with a narrow black border 
of the wings, growing somewhat broader at the anal angle of the hindwing; central part of the costal margin 
and basal half of the inner margin in the hindwing white. Under surface with a broad white band occupying 
in the forewing, as a large triangular spot, the whole central part; in the black border a double, white submarginal 
line. Hindwing with a black basal band leaving the costal margin free, marginal part broadly black, the blue
