COSCINOCERA. By Dr. A. Seitz.

orm, is said to be larger, but otherwise to differ little from maenas, and as both the latter and (liana are also 
reported from Java, it may be merely a generation-form or a casual form. — ignescens Mr., from the Andamans, 
which Rothschild, Hampsont and others consider to be a distinct species, on the contrary exhibits the brown 
colour increased to such a degree that it occupies the greater part of the wings and the dark basal spot is 
confluent with the postmedian band; the basal brown of the hindwing is likewise increased and distally irregu¬ 
larly defined. — latona van Eecke, from Celebes, shows the brown colour increased in the $ as in ignescens, the 
yellow colour being embedded in it at various places forming spots, especially around the central lunae, before, 
the apex of the forewing and in the basal area, also the yellow colour forms a postmedian notched band through 
both the wings. — isis South (54 a) is in the male above quite dark brown with but scanty, yolk-coloured 
embeddings, likewise dusted with dark; light yellow are only the last two thirds of the tail-flag. The notching 
of the postmedian transverse line is intensified only in the costal half of the forewing, otherwise but very little. 
A. heterogyna Mell (55 B a). The A is easily recognizable by the dark purple red distal-marginal stripe 
of the hindwing beginning below the apex and extending into the base of the rather long tail of the hindwing; 
this stripe is double owing to its centre being of a brighter tint. Moreover, the brown colour of the costal stripe 
in the forewing extends to the upper edge of the central eyespot. Colour of <$ yellow. The $ is pale Nile-green, 
at the thorax and base of the wing almost white; the marginal stripe of the hindwing and the brown colour 
right above the eyespot of the forewing are absent, whereby the $$ resemble those of selene. heterogyna is most 
similar to the palaearctic sinensis which it seems to represent in the Indian Region and in which we also often 
notice traces of the antemarginal stripe of the hindwing and the brown bridge from the costa of the forewing 
to the eyespot. Southern China. 
A. rhodopneuma Bob. (55 C b) is a southern form of the palaearctic A. dubernardi Obth. (Vol. II, p. 211), 
likewise exhibiting in the E a pinkish-red distal margin of 10—12 mm width in both wings. The eyespots of 
the hindwing are recognizable, but very feebly and indistinctly defined, as is also the case in the South Chinese 
dubernardi. The only remarkable differences are exhibited by the shorter though broader tails of the hindwings 
of rhodopneuma ; moreover, it shows the distal transverse stripe of the forewing more intensely developed, 
closer to the distal margin and curved upwards above the inner margin; it is also continued just as strongly 
through the hindwing, as far as the base of the tail; moreover the antemedian dark transverse stripe is intensified 
in both wings, whereas in dubernardi it has disappeared except for very faint traces. From the Naga Hills. 
B. Tails of the lepidoptera sabre-shaped, shorter than the costal margin 
of the forewing. Larva set with roundish knobs. Pupa in a paper-like web.

A. selene Hbn. (= luna Cr. nec L., dianae Hutt.) (55 C b). As to the great number of palaearctic forms 
cf. Vol. II, p. 211, pi. 33. — ningpoana Fldr. ( = astarte Mssn. & Weym.) presumably passes over to the Indian 
Region, since it also occurs in Formosa. The chief difference from typical selene stated by Felder — i. e. the 
smaller central eyespot — is apparently not constant, as also South Chinese selene from Hongkong, where I 
often found this species very abundant, vary in this respect. The $ figured in Vol. 2 I took on the 4th of 
May in Shanghai, where the form seems to be most typical. — calandra Jord. exhibits in the $ a yellower 
ground-colour, the central eyespots of all the wings are smaller; in the $ the cross-vein of the forewing is 
bordered inside with black, outside with red, and the tail-appendages are without pink, but the interior border 
of the marginal area and the exterior border of the basal area are a blackish olive. From the Andamans. - 
Larva green with a broad light yellow lateral stripe, the knob-shaped tubercles on the 2nd and 3rd segments 
are yellowish-green, thick, the others in the adult larva smaller, reddish-yellow. Head and anal spot blackish. 
On fruit, particularly Mango, Juglans, cherries, apples, but also on willows and other foliage trees and orna¬ 
mental bushes in gardens. — Common; the species is now much imported into Europe and bred every year in 
large zoological gardens. In captivity the first generation is most advantageously fed with Juglans regia or 
Carya. In the 2nd generation it is recommendable to feed them with willow from the beginning, because there 
may be a lack of food in the beginning of October, when the leaves of the Juglans fall off. It is also advisable 
to avoid not only changing the kind of food but even the food-tree itself, as the larvae are very sensitive in 
this respect. 
2. Genus: Coscinocera Btlr. 
The Coscinocera exhibit the long sabre-shaped tails of the preceding genus, though only in the males, 
and the colouring, the uncommon size and almost the same shape of the forewings as in the following genus. 
The genus is unique in the shape of the $ hindwings, the anal portion of which terminates in an obtuse lobe 
which is strangulated to a neck. We find traces of this strangulation of the anal portion of the hindwing already 
in the Attacus-iorm lorquini the $ of which shows an indentation behind the centre of the margin, corresponding 
with a slight concavity of the inner margin, above the termination of the distal transverse band. In fresh 
specimens we may easily notice that also in lorquini the wing is arched, for which reason it makes a fold in the 
centre of the margin, if the wing is flatly pressed down in spanning the insect. This distortion of the wing of 
Attacus lorquini may be regarded as the first step in the longitudinal extension of the wing of Coscinocera. but
