green head. The figure of the larva by Horsfield and Moore is called bad by Piepers, but be does not mention 
a better one nor the food-plant. The imagines are often common at their habitats; they rest on the twigs of 
bushes and, perhaps owing to the long delicate wing-appendages, they fly timidly and cautiously, though not 
very slowly. The very long middle tails are a little trailing in this flight, so that de Niceville thought to 
have noticed a certain resemblance to dragon-flies, and of the possibility of mimicry. I have not noticed 
any such resemblance and take mimicry to be impossible here. 
69. Genus: ]tfeomyr!na Dist. 
This genus contains an unmistakable very large, quite white species with 2 tails, of which that on the 
lower median branch is more than 2 cm long. 
N. hiemalis G. tfc S. (159 b), from Malacca, Siam, Berina, and the Mergui Is., is white with a black hiemalis. 
apical margin which in the form nivea Godm. (159 b) from the Island of Billiton recedes more in the hindwing, nivea. 
Beneath both wings are traversed by chains of spots filled up with a light bluish grey and surrounded by blackish. 
In the the dark apical portion above is covered with a violettish blue; in the form periculosa Fruhst., from periculo.sa. 
Sumatra, the costal margin is more broadly bordered with a bluish-grey. — As to the habits of this rare imago, 
nothing is known to me. 
70. Genus: Cheritrella Nic. 
Subcostal vein of forewing with 4 branches, but the cell of the forewing being very broad in Neomyrina 
(and also in Cheritra) is here much narrower. Particularly conspicuous is the stunted apex of the forewing. 
Shape of the tails on the hindwings as in Neomyrina, but the small tail on the lower median branch is not quite 
so long. Only 1 species: 
Ch. truncipennis Nic. (159 a). Forewing violet. Hindwing with a more deep blue lustre, all the margins trundpen- 
of the wings blackish-brown except the hind-margin of the forewing. Under surface umber-coloured, at the 
centre and end of the cell light-centred transverse streaks and a dark dentate line before the marginal area. In 
the $ the blue above is reduced. Sikkim, Assam, Upper Burma. This imago is very rare (de Niceville). 
71. Genus: JSTeoelteritra Dist. 
Separated by the twice bifurcating subcostal vein in the forewing. From Cheritrella and many other 
genera it differs in the small tail on the sub median being the long one (as long as 3 cm) and that on the 
lower median branch the shorter one, thus contrary to Neomyrina and Cheritrella. 
N. amrita Fldr. (159a). $ above black, in the forewing blue reflection at the base of the costa and amrita. 
in the disc; hindwing quite lustrous blue with a black basal portion and a black marginal marking. $ above 
quite similar to that of theodora (159 a), but instead of the black band traversing the white anal portion of 
the hindwing there are in the white area 3 separate, round black spots. Beneath the forewing is orange, 
towards the base paler, the hindwing is bluish-white, at the apex yellow, in the anal portion marked black. 
Distant already mentions reports from the patria of amrita, owing to which this species varies excessively. 
It can therefore not yet been decided which of the following forms are already sufficiently consolidated as to 
be regarded as separable local races or even as separate species. - theodora Drc. (159 a), from Borneo, exhibits theodara. 
in the $ the basal parts of both wings as far as beyond the centre, metallic bluish-green; in the $ the 3 dots 
in the anal white of the hindwing are united to a blackish-brown transverse band. — The form megalesia megalesia. 
Fruhst. is larger than Perak-specimens, and the basal area of the forewing above is lustrous light blue. Typical 
amrita occur in Malacca and Sumatra, but they are not common. 
N. namoa Nic. (146 B f). Upper surface of the almost as in the form mentioned last, but the under namoa. 
surface in the apical half of the forewing is not orange-yellow, but powdered with dark chocolate-brown. Described 
according to a single from the Battak Mts.; it might as well be an aberrative form of the preceding one. 
Another ,,species“ — nisibis Nic. is likewise described from Sumatra, resembling licinius ; but whilst here in nisibis. 
the white anal region of the hindwing beneath the last black spot is separated from the preanal line and is nearer 
to the anal angle, it coheres with the transverse line in nisibis. 
de Niceville thinks another lepidopteral form, teunga Drc., described as Sithon and unknown to me, 
to belong to this genus. From Borneo.
