NYCTEMERA. By Dr. A. Seitz. 
and smaller hindwings. — Sometimes all white or almost entirely white specimens are met with, in which only 
the veins are slightly shaded dark at the places otherwise coloured; I figure such a specimen from the Camotes, 
homologa. from Semper’s collection in the Francfort Museum, and denominate it ab. homologa ab. nov. (30 b). 
radiaia. N. radiata Wkr. greatly resembles sontica (30 a) originating from the same patria (the Philippines), 
but according to Semper it is said to vary little, and it has a white abdomen; the white ray in the sub¬ 
median fold of the forewing is mostly narrower, too. 
niasana. N. niasana Swinh. from the Island of Nias very much resembles radiata, but the discal band of the 
forewing does not reach the costa, and the marginal band of the hindwing is here much broader. 
absurda. N. absurda Swinh. from Salawatti, unknown to me in nature, is said to approximate sontica (30 a). 
Abdomen slate-colonred, curled white. Forewing brown with a narrow basal stripe as in alternatum (29 c, d); 
the white discal band is very broad, straight through the hindwing, divided into 10 spots by the veins, the 2nd 
spot from the costa is divided into 3 by the discoiclal and distal veins, and has a white stripe touching it on 
the outside, as well as another small one above. Hindwing with a narrow, brown marginal band as sonticum, 
extending to the costa as in alternatum. 
alba. N. alba Pag. (30 a). The wings on both sides snow-white, the thorax yolk-coloured, faintly marked 
black, abdomen white, at the end yellow, banded black. I figure the type from my collection; it originates 
from the Samoa Islands; Swinhoe states also the Fidji Islands as the patria. The species has, beside the colour, 
nothing in common with the white form of amplificata (cydippe ) from Nias, next to which Pagenstecher and 
Swinhoe place it, nor does it show any relations to the white Hainan-form of tripunctaria or celsia. Not common. 
A ala. N. kala Swinh. (30 b). Jet-black, the band of the forewing thickly parted by the veins, the margin 
of the hindwing very broad and indented in the middle. Abdomen black. From the Key Islands. 
luctuosa. N. luctuosa Volt. (= crescens Wkr.) (26 i) entirely resembles kala, but below the cell there is a 
triangular white spot, and into the white oblicpie band of the forewing a strong, black tooth extends on 
symia. the median fiom inside. In the Moluccas and North Australia not rare. — In syrnia Sivinh. from the Fergusson 
onetlm. Island the white spot below the cell of the forewing is absent. — In onetha Sivinh,. from New Britain the white 
A apauren- inner-marginal stripe of the forewing is absent and the basal wedge of it is of a more regular shape. — kapaurensis 
sis - Swinh. (30 b) resembles the preceding particularly by the jet-black ground-colour and the unspotted basal 
part of the forewing. But the discal band of it is irregular and also the marginal band of the hindwing is not 
uniform, but sinuously bordered. Kapaur. 
accepta. N. accepta Swinh. (30 b, misprinted into acceptans). The band of the forewing begins broadly right 
at the costa, being purely white, without dark veins; in the submedian fold a thick, wedge-shaped, white spot. 
The margin of the hindwing is narrower than in the preceding. Celebes; in the Minahassa not rare. 
g alb ana. N. galbana Swinh. (30 b). Very elegantly marked; the oblique band of the forewing makes a pointed 
tooth distally below the radial. Below the cell of the fore wing a thick wedge-shaped spot to which there is 
in most cases yet a small white spot suspended in the cell-end. In Luzon local, but not rare. 
pellex. N. pellex L. (= artemis Wkr., separata Wkr.) (30 b, c). The species is easily distinguished from 
all the preceding species by the white spots in the uniformly broad black margin of the hindwing distinctly 
prominent above and beneath. The abdomen is almost black, above quite finely, beneath somewhat more 
broadly curled light. The forewing has a white basal streak, a large, oblique oval spot and 3 submarginal spots. 
The proximal margin, moreover, is white in typical specimens. The size of the spots varies extremely, so that 
a great number of names could be distributed. The basal streak may be absent, or parted in the middle, 
tangens. terminate into a wedge, or be expanded to a band almost touching the white oval in the form tangens form. 
nov. (30 c). This white oval may be parted, reduced in size, notched at the margins and exhibit in front of 
signata. it a small spot at the costa, in some cases even be connected with it. — We only enumerate yet signata Btlr. 
(30 c) as a separate name for one of these forms, making an entirely deviating impression owing to the extra¬ 
ordinary blackening. The basal ray and white proximal margin of the forewing are absent, the oval is reduced 
to a small circular spot, on the hindwing not only the distal margin, but also the costal and anal margins are 
broadly blackened, and the marginal spots are obsolete. On the contrary, also supernumerary white spots may 
albipuncta. be inserted between the others, particularly at the margin, as far instance in the form albipuncta Druce ; or, 
amosa. as in amosa Swinh., the white marginal dots may be insignificant and reduced, the white discal spot, however, 
as well as the basal white so much increased that between them the ground-colour only remains as a narrow 
transverse bridge; this form is described from Dammer, albipuncta from Guadalcanal’. — pellex is widely distri-
