Th. hengis Sm. 6c Ky. (144b). Closely allied to wallacei (143 c) and vidua (143 d); larger than the hengis. 
former species, the wings broader and rounder, the upper surface in the $ of a brighter and more uniform blue, 
the white band in the hindwing narrower. On the under surface the black costal-marginal and apical border 
in the forewing narrower, as well as the white band in the hinclwing. $ above darker than wallacei- $, almost 
black, the black costal margin of the forewing at the base does not reach the inner margin, the white band 
in the hindwing is narrower, the same on the under surface, where also the blue marginal band is broader and 
encloses longer stretched spots. It differs from vidua- $ by the absence of the blue scales at the costal margin 
and of the white spot at the anal angle of the forewing above, as well as by the narrower and more sharply 
defined white band in the hindwing. German and Dutch New Guinea (Kapaur, Arfak District). 
Th. glaucopis Gr.-Sm. (143 d). $ different from wallacei by the rounder wings and their darker blue glaucopis. 
colouring. The black wing-margin in the forewing narrow and distinctly prominent, in the hindwing broader, 
the white band of the hindwing rather diffuse. Beneath the blue marginal band extends uninterruptedly as 
far as the anal angle, the white median band is in the hindwing narrower than in wallacei and forms in the 
forewing an extensive inner-marginal spot on the distal half. Basal band distinct, marginal band broad'with 
long-stretched, partly wedge-shaped, black spots. wing-contour and colouring as in wallacei, the light band 
above more brownish and less extensive. The white marking beneath somewhat more extensive than in the 
Humboldt-Bay and Wandesi. 
Th. dispar Sm. 6c Ky. (142 d). Allied to Th. glaucopis Gr.-Sm. (143 d). $•. upper surface of the dispar. 
forewing blue, only at the costal and distal margins narrowly bordered with black. Hindwing with a broad 
white band and a black marginal part, the base and the middle part behind the band blue. Under surface 
black with a broad, joint, white band extending near to the apex of the forewing and being narrowed in the 
forewing, the blue marginal band below the costal margin broad and distinct, along the border narrow and 
broken .up into spots. Hindwing with a blue basal band, the marginal band clistally broader than proximally, 
interrupted by oval, black submarginal spots. $ above black with au indistinct, joint, white median band 
receding greatly on the inner-marginal part of the forewing. Under surface like in the <$, the ground-colour 
deeper black, the white band in the hindwing narrower. Abdomen above with narrow white bands. New 
Britain; Bismarck Archipelago. 
Th. peri Gr.-Sm. (143 e). <$: the blue of the upper surface darker than in glaucopis (143 d), the white peri. 
band in the hindwing more prominent, also indicated on the inner-marginal half of the forewing; the black 
borders are broader, but the costal-marginal border in the forewing is absent. The black of the under surface 
deeper, the large white inner-marginal spot in the forewing with an irregularly prominent margin, the blue 
costal border of the forewing and the marginal band in the hind wing broader. Upper surface of the $ jet-black 
with a distinct, though rather narrow white band and, like in the with a narrow white marginal scaled border. 
Beneath like in the $, the white band and marginal border in the forewing somewhat narrower. German New 
Guinea (Stephansort). 
Th. regalis Sm. 6c Ky. (143 d, e). Allied to glaucopis. S, : upper surface bright blue, in the forewing regalis. 
only the marginal scales white, costal margin with a very narrow, distal margin with a somewhat broader black 
border. Hindwing with a rather prominent white band and a broad black border. Under surface jet-black, 
the white band in the hindwing rather narrow, forming in the forewing a large round inner-marginal spot, 
the blue marginal band in the forewing uniformly broad, rounded and reaching as far as vein 2, the marginal 
band in the hindwing broad, the black spots forming long-stretched, narrow ellipses. New Guinea. 
Th. dohertyi Oberth. (142 c) from Jobi is somewhat smaller than regalis, the forewing also in the $ dohertyi. 
above with a broad blue bordering of the white median band; beneath easily discernible by the black distal 
area of the hindwing being proximally and distally bordered with a broad metallic tinge, whereas the metallic 
median band is much narrower and hardly dark-pupilled. 
Th. drucei Sm. 6c Ky. (143 e, f). <$: upper surface similar to that of Th. regalis, but the blue lighter, drucei. 
the black border, also in the hind wing, narrower. The under surface differs from that of regalis by the remar¬ 
kably broad white band of the hindwing and the very extensive inner-marginal spot in the forewing, touching 
outside the margin, inside almost the blue marginal band and enclosing a small black spot close in front of 
the anal angle. blackish-brown, the white spot of the forewing long drawn out, reaching at the inner margin 
not quite as far as its half, anteriorly as far as the anterior cell-end and distally about as far as 4 / 5 of the 
length of the wing, at the base scaled bluish, as well as the white basal area of the hindwing, which is blue also 
at the distal margin. Under surface on the whole as in the in the forewing the black spot before the anal 
angle is absent, the blue marginal band is narrower. New Guinea (Ati On). 
Th. horsa Gr.-Sm. (144 b, c). above similar as in hengis, darker blue, forewing without any white, horsa. 
Forewing without the white band, only with a narrowly white-bordered costal margin, the black margin broader 
and at the veins rather deeply dentate. Forewing beneath extensively black with a large, white, round inner- 
marginal spot not reaching the border; the blue marginal band beyond the middle interrupted, extending 
along the border as far as vein2; the white band in the hindwing does not reach so far to the apex as in hengis, 
the marginal band very broad as in hengis, but of a still darker blue, the black spots large and long drawn out,
