A. mylittoides Bouv. likewise originates from Java and differs from surakarta in the central eyespots myliltoides. 
being elliptical. 
A. delegata Stvh. is of a brighter ochreous red; antennae pale red-brown, collar and costa of forewing deler/afa. 
steel-grey. In the the ocelli are narrow, in the $ large and round, surrounded by brown, then with a pale 
yellow line and bordered with blackish. Interior of both wings covered with yellow spots which are of a bright 
ochre colour in the 1 triangular spot in the cell near the base; 2 distally angled, discal thin brown bands 
through both wings are close together, the exterior one outside edged with grey, the space from this band to 
the margin monotonously dark reddish ochreous. Near the apex of the forewing a yellow subcostal streak. 
Singapore. The marking above is similar to that in frithii where, however, both sexes are similarly coloured 
and marked; besides, the hyaline eyespot is here narrow also in the <$, not round as in frithii ; it is also allied 
to larissa. 
A. fickei Weym. is unknown to me in nature. It is said to resemble frithii Mr. (53 b), but to be easih’ fickei. 
discernible by a brown longitudinal stripe through the forewing, extending from the base of the forewing about 
2 mm broad along the median vein, widening distally and then gradually passing over into the brownish 
ochreous ground-colour. Described from Sawangan (North Celebes). 
A. pristina Wkr. is ochreous. Thorax in front blackish-grey. Wings with 3 oblique purple brown pristina. 
dentate transverse stripes composed of crescents, the first stripe being narrow, the second broad, the third 
interrupted. Eyespot surrounded by dark brown with a moderately large hyaline centre; before the apex a 
dark purple brown costal spot. Hyaline spot in the ocellus of the hinclwing small. New- Guinea. - Described 
as Antheraea, but probably it is rather an Opodiphthera. 
A. sciron Ww. — inversa Bothsch., $ = alephostra Swh.) (56 A a). Ochreous orange, in places with sciron. 
an intense red tint: in the forewing 4 thick nebulous streaks dusted with brown; the first of them cuts the basal 
quarter, the second traverses the central eyespot and touches the 3rd behind the centre of the inner margin, 
the third extends from the apex obliquely through the wing; the 4th is broad, undulate, and separates the 
marginal area from the disc. The eyespot of the forewing is a large round vitreous spot surrounded by dark. 
Hindwing with 3 stripes: the first cuts off the basal half of the wing towards the marginal half and extends 
across the inner edge of the somewhat oval ocellus; the second is arched, distinct; the third undulating, indis¬ 
tinct. Papuan; described from the I. of Waigeu. 
A. saccopoea Trnr. Spanat. 85 (A )— 105 (£) mm. Apex of forewing strongly curved, rounded rectan- saccopoca. 
gular. Violettish reddish. Eyespot small, circular, feebly surrounded by violettish brown, inside finely edged 
with white, then with purple. Centre slit-shaped, hyaline. Subterminal line whitish, on both sides bordered 
with violet, almost straight, from before the apex to % of the inner margin. At the apex a dull purple violet 
spot. Hindwing coloured like forewing, but the eyespot without the hyaline central slit, subterminal line curved 
and undulating; an antemedian dark nebulons stripe. — The larvae pupate in large, loose webs in which each 
spins its own cocoon, about 20 in one nest; they feed on a tree called ,,wild pear“. — From the description we 
cannot decide whether it belongs to Caligula or Opodiphthera. The species is unknown to me. 
11. Genus: Opodiphthera Wllgr. 
This genus containing but few species from the Indo-Australian Fauna can hardly be separated from 
Antheraea and at the same time forms a connection with the following Caligula. The insects are chiefly 
distinguished from the mostly heavy Antheraea by their more graceful structure, nearly all the males being- 
light yellow, the ocelli usually smaller than in Antheraea , not very prominent. The genus differs the most from 
Antheraea in the larvae which, as far as they are known, are variegated. Type: varicolor Wllgr. (= astrophela 
Wkr.) 
0. astrophela Wkr. (= simplex Wkr., varicolor Wllgr.) (56 A d) is a most variable species the different astrophela. 
forms of which, however, can hardly be regarded as geographical races. Forewing of $ shorter than in eucalypti , 
helena, or janetta. Colouring mostly light chrome colour, both wings with a distinctly marked purple black 
transverse band, the antemedian band of the forewing pierced midway and the anterior portion distally removed. 
Ocelli on all the wings reddish-yellow, pupilled with white, towards the base with a reddish and white crescent, 
the whole surrounded by black. Costa and patagia dark grey, head, antennae and abdomen yellow-. 5 reddish 
brown, in the marginal halves of both wings longitudinal rows of small light oval spots being also recognizable 
in the though less distinct. — Larva on Elaeocarpus obovatus and Podocarpus elata, in some places in masses; 
black with yellowish-green, parallel longitudinal bands and whitish tubercles. For the pupation the larvae 
gather and spin their narrow-meshed cocoons close together, so that in some places, e. g. on the Richmond 
and Clarence Rivers, they cover the bushes in heaps. The pupae, though being frequently parasitized, are said 
to be eaten by the natives. The imagines fly very swiftly though unwieldily and often collide. 
0. fervida Jord. orange yellow, of a much brighter colouring than astrophela , and with longer fervida. 
antennal branches. In the forewing the veins are more intensely marked brown between the cell and the exterior
