NYCTIPAO. By M. Gaede. 459 
10. Genus: ]Jlyctipa© Him. (Erebus Lair.) 
Palpi elongate and erect, the 2nd segment moderately hairy; abdomen without tufts; all tibiae with 
spurs. The cell short on both wings. Apex of forewings acute, outer margin of both wings undulate. Type: 
crepuscularis L. from Japan. In Vol. Ill, p. 322 five species were mentioned, which with the exception of two, 
occur with many others in the indo-australian territory. All the illustrations on pi. 45 have been slightly reduced. 
1. In d vein 3 extends into the apex, veins 4—8 in a small lobe at 
base of wing. 
N. purpurata Drc. (= aroa B.-Bak.) (Subgenus Argiva Hbn.) (50 c). Forewings of black-brown, purpurata. 
apex of forewings somewhat paler, wings with bluish gloss. On forewings a large ocellus with indications of 
an inner line and a continuation of the dark surround to the ocellus towards the inner margin. Underside 
dark brown, a yellow-white patch near the apex. The $ is less dark. On forewings a distinct, vertical, un¬ 
dulate antemedian line. Ocellus distinct. The inner lunule with smoky brown centre, the rest dark, then 
black to the inner margin of the lunule. The black edge of the ocellus continues in 2 arcs to the inner mar¬ 
gin. At 14 of apex a wide oblique white streak. 95—100 mm. Solomon Islands, New Guinea. 
N. hieroglyphica Drury (= harmonia Cram., mygdonia Cram., ulula F.) (44 e). Forewing of B black- hieroglyphi- 
brown. On forewings outer margin faintly paler. Ocellus like an inverted comma, with brown centre and ca ‘ 
black edge, extending outwardly heavily black. A narrow oblique yellow-white or brownish subapical band, 
that may also be split and that does not extend to margin. In $ ground colour is grey-brown with distinct 
dark striations. Subapical band white or yellow, similarly a spot below vein 4. Antemedian line undulate, 
vertical, faint. Submarginal line punctiform, somewhat incurved behind the cell, bending outwards at vein 4. 
On hindwings antemedian line is still less distinct, outer and submarginal lines in the form of spots, varvingly 
distinct. — lunaris Wkr (= celebensis Hpjfr.) only differs in the prolongation of the subapical band to the lunaris. 
outer margin. According to Swinhoe, lunaris is a separate species. These two forms occur throughout India, 
Tonkin, Malacca, Sunda Islands. — tenebrata E. Prout (= purpurata Hrrtps.) differs in the by the complete tenebrata. 
absence of any sign of the paler markings on forewing both on upper and under sides. In $ the pale mark¬ 
ings are reduced, especially on underside. The subapical stripe on forewings is very narrow. The differs 
from purpurata Drc. by an enlargement of the origin of veins 2—5 on fore wings. This form apparently 
only occurs on Borneo. 75—90 mm. 
N. sumbana Swh. The <$ is similar to lunaris, but the yellow-white subapical band is still shorter sumbana. 
than in hieroglyphica and is divided into two parts. In $ forewing is ochreous brown in the inner %, the 
remainder being black-brown. Ocellus as in $. Subapical band white and short, consisting of 3 patches, the 
two lower ones being large, the third one small. Hindwings with a large white spot anteriorly. Sumba Is¬ 
lands. — luzonica Swh. 3 black-brown. The inverted comma mark very indistinct, without any blue or white luzonica. 
scales. The subapical band is formed of a dark chrome yellow line. Hindwings devoid of markings. Luzon, 
ceramica Swh. (50 b). S black-brown. The comma mark scarcely discernible on forewings. The ochreous white ceramica. 
subapical band is more boldly curved, somewhat expanded at costa, almost extending to margin. In $ the 
inner % are ochreous brown. Only the black circular ocellus is distinct, conjoining it a boldly curved black 
line to inner margin. The outer third dark brown. Subapical streak wide, narrower distally, ending bluntly 
shortly before the margin. In centre of wing a large white spot. Hindwings dark brown in basal half, ochreous 
brown outwardly, separated by indistinct white patches. From Ceram. All forms 75—90 mm. Described 
as species owing to small differences in the genitalia, but possibly all merely hieroglyphica forms. 
N. strigipennis Mr. (45 a). Recognisable by the obsolescent brown subapical band in £ and $. Fore- strigipennis. 
wings of (J dark brown, marginal area more greyish brown posterior to the dentate submarginal line. The in¬ 
verted comma mark rusty brown. The ocellus outlined outwardly by a black line. From lower centre of the 
circle around the ocellus, an oblique line to inner margin. Hindwings only dark to the centre. The $ is some¬ 
what paler, the division between the pale and the dark areas is more distinct. terminalis <$ Strd. Marginal terminalis. 
area of both wings is greyer. On forewings a grey dentate line proceeds from the subapical band to the inner 
margin. On hindwings a black-brown outer and submarginal band are visible. 75—85 mm. India, Tonkin. 
2. On hindwings of $ the lobe at base is not so distorted and small, 
vein 4--8 consequently better developed. On the lobe are distinct andro- 
c o n i a. 
N. caprimulgus Fabr. (truncata Mr.) (45 a). The $ owing to its dull colouration, similar to purpurata, caprimulgus. 
but easily differentiable by the different shape of the hindwings. The inverted comma mark with a few blue 
scales. The outer black edge of the ocellus is heavy. On underside of forewings large white spots as the outer 
line, these are somewhat displaced outwards at vein 7 and 4; on hindwings merely minute dots. The $ is 
recognisable by the central line on forewings, which encircles the ocellus in a single bold arc, extending below 
in a sharp point far inwards and then in 2 arcs vertically to inner margin. Postmedian line forms an obtuse 
angle both below vein 7 and 4.
