which resembles the d\ and 2-form hormenia H.-Sch. (3e), in which the hindwing has broad white streaks, hormenia. 
which sometimes occupy the greater part of the wings. Transitions between these two 2-forms, which occur 
together, are very common. Plentiful in North India from May to August, like the other midamia forms so 
similar in flight to Euploeids as to be easily mistaken for them. — alcathoe subsp. nov. inhabits Tenasserim; alcathoe. 
in this the anal angle of the hindwing and a row of stripes before it are dirty white as in the 2-form 
hormenia, but the band does not extend so far towards the base, and there is only a small spot in the 
cell. — submaculans Walk, occurs in two individual forms. The <? of the name-typical submaculans submaculans. 
(— juvenis Btlr.) resembles the Indian midamia , but has on the under surface very little if any blue: in 
the 2 the proximal white spots are small or streak-like. In the second form, striata Druce (3e) & and 2 striata. 
have white streaks in the basal half, and the white discal spots are larger than in the non-streaked form; 
the forewing is either blue at the apex or without blue. This difference of specimens reminds one of the 
variability of Papilio paradoxus telesides Fldr. (1864), which occurs in the same district. Malacca, East 
Sumatra and Borneo. — trepsichrois Btlr. (3e) inhabits Nias (probably also the other islands off the west trepsichrois. 
coast of Sumatra, perhaps with the exception of Engano, where the forms are usually very divergent). The 
white submarginal dots are large on the forewing in cf and 2; the blue is absent above and beneath or 
only present above; the 2 is streaked. — padangana subsp. nov. cd: wings above and beneath without padangana. 
blue. Forewing with two rows of spots, the discal spots small, the submarginal ones somewhat larger, but . 
not so large as in trepsichrois. Hindwing with a small cell-spot and bwo rows of spots between cell and 
margin, merged together posteriorly into four long streaks, which do not extend to the base. Padang 
Bovenlanden, South-West Sumatra. — dolosa subsp. nov. cd: paler brown than the other forms. Forewing dolosa. 
above narrowly blue before the apex; the upper three submarginal spots almost as large as in trepsidirois, 
the five posterior ones small, the discal spots likewise small. On the hindwing before the margin a band 
of broad white streaks, which do not reach the cell and are two to three times as broad as the brown vein- 
streaks, the costal streak extending to the base, the next two above incompletely divided into two spots 
each, the separation complete beneath, the hinder margin narrowly white almost to the base; a white dot 
in the cell. Preanger, Java. 
17. Genus: Gynautocera Guer. 
Frons broad, not pointed above. Forewing very long, the margin very oblique and almost as long 
as the hindmargin; in the forewing many costal veinlets, 1. and 2. subcostals free, 3. to 5. subcostals 
stalked, 5. subcostal placed proximally to the 3., 1. radial from the cell, upper angle of the cell projecting, 
2. and 3. radials arising close together or short stalked, 1. median about at the same height as the t. sub¬ 
costal ; cell of the hindwing obliquely truncate anteriorly, the discocellular weakly if at all angled, 1. and 
2. radials and again 1. subcostal and 2. median at the same height or 1. subcostal more proximal than 
2. median. — North India to the Moluccas; partly mimics of the poisonous Aristolochia-Papilios. At rest 
the wings lie flat one over another. 
G. papilionaria Guer. (= selene Roll.) (3f). Black; vertex, the black-spotted under surface of papiiionaria. 
the body and some spots at the base of the wings beneath red; veins in the distal part of the forewing 
pale; hindwing with somewhat bluish green sheen, with or without a white spot edged with green. In ab. 
fraterna Moore this spot is lengthened into a band, whilst in ab. zara Swinh. (= rara Hamps .) it is pale fraterna. 
blue. — Himalayas, Calcutta, Assam, Burma, Tenasserim, Annam, Tonkin and Hainan: at low elevations all zara - 
through the summer. 
G. philomela. Very similar to the preceding species, perhaps not specifically different. Hindwing 
without discal spot, on the other hand green or white at least at the margin. Sumatra to the Moluccas. — 
pavo IJohrn. Forewing strongly falcate. Hindwing with a green marginal band extending to the pavo. 
cell, which encloses spots of the black ground-colour. North-East Sumatra. — philomela H.-Sdi. (3f). philomela. 
Hindwing with grey-white marginal band, not extending to the anal angle. Java, Lombok. — celebensis ce/ebensis. 
Rothsch . Hindwing with green-blue marginal band; beneath the middle veins whitish before the margin. 
Celebes. According to Semper a similar form, not more closely described, occurs on the Philippines. -— 
buruensis Rothsch. (3f). Hindwing blue, black at the base, above with indications of black spots before buruensis. 
the margin. Buru. — virescens Fldr. Hindwing bluish green, black at the base, above without indica- virescens. 
tions of black spots before the margin. Southern Moluccas: Amboina. — reducta Rothsch. (3f). Smaller reducta. 
than virescens ; hindwing above more broadly black at the base and costa and also beneath less extended 
green than in virescens. Northern Moluccas: Batjan. 
18. Genus: Hist hi Hbn. 
Closely allied to Gynautocera and Cyclosia; 1. subcostal of the forewing anastomosing with the costa: 
hindwing produced into a long point or the margin at least angled in or before the middle. Larva dark 
brown, tubercles red. — Indo-Malayan, extending in China into the Palaearctic Region. The insects rest 
like the other Chalcosiids with the wings folded flat over one another.
