N. albicollis Rothsch. Head and thorax steel-green, collar snow-white; abdomen black with a yellowish- albicollis. 
white anal tuft. Forewing at the base deep steel-blue with a concave distal bordering; behind it a bread white 
transverse band, distally bordered by a lustrous metallic blue median band; the distal half of the wing is coppery 
carmine, bordered with black. Forewing at the base diaphanous white, distally black. The larger $ is coloured 
darker, the white more cream-coloured, the blue colour replaced by black, the distal half chestnut-brown. Length 
of forewings: 11 mm, $ 12 mm. Mount Goliath, Dutch New Guinea, in February. 
N. albata Rothscli. Body black, in the <$ above lustrous blue; palpi and legs yellowish, the scales of nlbaia. 
the latter partly blue, particularly on the forelegs. Basal half of the posterior tibiae, apex of the posterior femur, 
1st tarsal joint partly white, while a large spot behind at the mesosternum is totally white, anal valve cream- 
coloured. In the <$ the venation is curved by the scent-organ, the costal margin of the forewing being bent 
up. Fringes with long scales placed backwards. The width of the cell strongly reduced. On the fore-and hindwing 
there is a large hollow near the base. Base of forewing blue, near the base a broad, white band continued into 
a broad, purple-blue band strangulated in the middle; disc purple-orange, apex and distal margin, as well as 
the costal margin black, metallic purple, in a lateral light with an intense lustre, near the apex a minute white dot. 
Hindwing white, distally and at the proximal margin bordered with an olive-black, the band at the apex broadest, 
at the anal angle very narrow. Beneath like above, but without a metallic blue lustre. The blue bands of the 
forewing in some parts replaced by olive-black. $ similar, the anal tuft above smoky grey, beneath white; 
the white bands of the forewings broader than in the with a thin blue distal margin. The black distal margin 
and the costal margin are thin, at the apex scarcely broader than at the anal angle. Length of forewings: 9 to 
10 mm. New Guinea. 
N. aequalis Rothsch. similar to albata, head and upper side of thorax dark metallic greenish-blue; aequalis. 
forewing above the same, the costal fold as in albata, so is the hollow on the fore- and hindwing; behind the 
costal fold a small white spot with some small white scales in front and at the margin, a badly marked discal 
band from the costal margin to the anal angle purple-orange, very much scaled metallic greenish-blue, particularly 
in the middle. Hindwing purple-black with a broad, whitish proximal part of the marginal area, almost triangular, 
narrower than in albata. Under-surface purple olive-black, on the forewing a small, white basal streak, the 
white subapical dot as above. Proximally to it a conical, orange-brown longitudinal spot. $ like the <$, forewing 
with the white spot near the base like above, of a very variable size and with a large white basal spot beneath. 
Length of forewings: 9 mm. New Guinea. 
N. leucodera Rothsch. <$: head and thorax above metallic greenish-blue, the rest of the body olive- leucodera. 
black, faintly purple; collar with two small white dots. On the chest laterally a spot and the basal half of the 
first tarsal joint white, anal valve fawn-coloured. Forewing above with the costal fold as albata, but smaller. 
On the fore- and hindwing no hollow, both metallic greenish-blue like the thorax, a subbasal band from the 
costal fold straight to the proximal margin, in front of it a small dot on the costal fold and a round, subapical, 
white spot; proximad to this subapical spot a purple-orange spot, obliquely oviform, from the 3rd subcostal 
vein to the 2nd median vein. Hindwing olive-black with a bluish reflection. A large, white, triangular area 
from the costal margin to the 2nd submedian, the black distal band on the submedian being one and a half 
times as broad. $ like the <$, the white spot of the wing some hat variable, the subbasal spot on the forewing 
smaller than in the the purple-orange spot also lighter. Length of forewings: 9 mm. In the colouring it 
resembles aequalis, but it is easily distinguishable by the white collar and the by the diffeent scent-organ. 
New Guinea. 
N. poecila Rothsch. §: head and thorax above metallic blue, rest of the body olive-black with a poecila. 
purple reflection; collar with two contiguous white spots as in leucodera. Legs without any white. Forewing 
narrow, the 3rd radial petroled with the 1st median vein, metallic purple blue from the base to the middle of 
the wing. This area is distally curved, behind it a large, brown-orange distal spot not cpiite reaching the costal 
or proximal margin and margined with a metallic purple-blue; this border is dentate; the distal margin, costal 
margin and fringes are black. A central spot near the base white. Hindwing of a more triangular shape than 
in other species owing to the less rounded apex, olive-black, faintly purple, from the costal margin to the 2nd 
submedian a large, white basal spot, its distal margin cuts the median at the base of the 2nd median vein; the 
posterior margin black, from the middle to the base narrow. Under surface purple olive-black. Forewing with 
a white subbasal spot which is shaded by olive; an orange-brown, subapical. longitudinal spot. The white spot 
on the forewing as above. Length of the forewings: 9 mm. New Guinea. 
N. basinitens Rothsch. Head and thorax black, suffused with a dull steel-green, antennae black, collar basinitens. 
white, abdomen black with a reddish-grey anal tuft. On the forewing the basal two fifths are steel-lustrous 
bluish-green, the distal three fifths copper-red, bordered with black. Hindwing in the basal half white, distally 
black. Length of hindwings. IU/2 mm. Mount Goliath, Dutch New Guinea, in February.
