APPORASA. By Dr. A. Seitz. 
larger specimens with a deeper violettish-blue upper surface and a narrower black margin; under surface of 
<$■ chestnut-brown, of $ violettish-brown; from the Kottawah Forest near Galla (Point de Galle). The latter 
forms are presumably occasional deviations or dimorphous forms (as de Niceville already presumed) which 
damna. are hardly dependent on certain localities. They have been denominated darana Mr. and are presumably a 
hainana. subordinate branch of anita Hew. described from Siam, just like hainana Crowley which is to be recognised by 
its size and described from Hainan. — Fruhstorfer presumed still more undescribed local forms from the 
Andamans (which have been made known in the meantime), from the Sumba and Sula Islands, where narada 
andamani- occurs everywhere. The Andaman form andamanica Riley is in the $ above more blue than violet and 
ca - has a darker under surface. In the $ above the blue areas are likewise more extensive. As such fine distinctions 
were formerly not made, we find the Ceylon-race sometimes denoted as narada or anita or erichsoni. — The 
erichsoni. most distantly remote is erichsoni Fldr. nec W .-Mas. <£• Nic., from the Philippine Is., which is rather similar 
to anita, but in the <$ above of a magnificent blue. — Another form is known from the Moluccas (Batjan) : 
batjana. batjana Riley. Above also in the B with a very broad black margin, recalling plateni', but whilst in the latter 
the proximal border of the marginal band runs almost straight ly, it is strongly curved in batjana. In Celebes 
confusa. (Macassar) the form confusa Riley flies; in the above the blue is thinner, lighter, more confined to the proximal 
plateni. parts of the wings. -—- plateni Riley is the easternmost form; separated from narada narada, salvia, and 
erichsoni by the great extent of the black margin occupying the whole costal area of the forewing from 
the costal margin to the upper cell-angle, the whole apical part of the wing, and being even at its narrowest 
place (in cell 1) more than 3 mm broad, so that the black colour covers more than the whole distal halves of 
the wings. Under surface tinged with greenish, otherwise marked like erichsoni. The $ has above only on the 
forewing a large blue spot, whilst the hindwing is but slightly scaled with blue. Apparently confined to Mindanao. 
— Larva light green, dorsum whitish with distinct dark indentations and a dark dorsal line. Head black, neck 
and terminal rings marked dark; on young shoots of Olax. Pupa light green, shaded darker. The insects are 
rather common in most of their habitats, particularly in Ceylon, near Kandy; they fly rather swiftly, like an 
Arhopala, and prefer settling down on leafless parts of twigs, with their wings closed, resembling a dry leaflet. 
I have never seen them resting with their wings widely opened, as the Arhopala amantes flying at the same 
place. Repeatedly I also observed them in gardens near Colombo. They only fly for short distances. 
annetta. H. annetta Stgr. (148 a) is probably only the representative of the preceding species in the Moluccas 
and in parts of the Papuan District. Easily discernible from the narada- forms by the reduced blue areas of 
the upper surface and the different shape of the hindwing, the margin of which is more convex and the small 
tail of which is more slender at the base. Typical annetta come from Batjan (Moluccas). — From Amboina 
anna, and Saparua anna Stgr. is known, the S of which has a more lavender-blue upper surface and a more intensely 
faisina. marked under surface; the $ exhibits a greenish reflection on the blue upper surface. • — faisina Rbb. from the 
fabiana. Bismack-Island Faisi is smaller, and both wings beneath are crossed by a broad light band. — - fabiana Fruhst. 
is above darker blue than faisina, the blue area of the forewing is more distinctly defined against the marginal 
black; beneath light grey with a broad, distally undulately defined median band and a black submarginal band 
which is proximally bordered with whitish-grey on the hindwing. The somewhat lustrous golden spots in the 
eberatda. anal part of the hindwing of faisina are here grey and broader. Waigeu. — eberalda Fruhst., from Kaiser 
Wilhelmsland, shows the basal part of the wings above dark violet, whilst the under surface is dark brown 
elga. with an obsolete black median band; in the $ the tinge of the under surface is more reddish. -— - elga Fruhst. 
from the Island of Obi, has a more extensive and intensely lustrous light blue basal part in all the wings instead 
of the dull dark violet in annetta. Beneath it is light red-brown instead of blackish-brown. 
39. Genus: Apporasa Mr. 
This small genus exhibits a shape of the wings different from the genuine Arhopala *). The hindwing 
Sends a broad triangular continuation at the end of the costal margin in front, so that it projects into a light, 
somewhat glossy area on the corresponding place of the forewing beneath. 
atkinsoni. M. atkinsoni Doh. (147 g). The shape of the forewing of this species differs a little from the others 
in the two dents at the margin below the apex, upon which peculiarity Moore founded the genus Apporasa 
(1884). Upper surface brown; on the proximal half of the wing there is a metallic blue gloss; the costa of the 
forewing is spotted white. Beneath the hindwing shows confused markings, whilst the forewing shows the 
costal transverse bands being usally found in the Arhopala. Both sexes are very similar, but the q is somewhat 
smaller and the blacker basal part removes the metallic violettish-blue farther towards the centre of the wing. 
Burmah, Tenasserim; rare. 
*) We keep up here the name Arhopala, since Ambtypodia is ambiguous.
