S. taiwana Miyake is closely allied to cyssaea Stoll, but has the hyaline spots on the forewings taiwana. 
considerably larger, and below the apex some white marginal scales. On hindwing the two hyaline spots 
united as in S. fortunei. 31 mm. Formosa- 
S. ribbei Roeb. (= polusca Druce ) (tig) is just as slender, although larger than tenuis. Body black with ribbei. 
blue metallic lustre, metathorax orange. Forewing with wedge-shaped white transparent spots, otherwise black 
with blue lustre. Hindwing iridescent bluish-black, orange at base. Minahassa, Celebes. 
S. interrupta Willem. Black with yellow markings. Head black, face yellow, tips of antennae black, interrupta. 
above white. Tegulae, patagia and hind margin of thorax yellow. Abdomen with 7 yellow bands, the first 
one broken, the 3 last ones confluent. On forewing 5 hyaline spots, 1 at base yellow, 1 triangular in the 
cell, 1 below it, intersected by rib 2, and 2 beyond the cell each of which traversed by a vein. Hindwings 
hyaline with broad black border protruding proximally in the middle, and a few yellow scales at the inner 
margin. 37 mm. Formosa. 
S. lucerna Wilem. is black with yellow markings; face pale ochreous, thorax spotted with yellow. Abdomen lucerna. 
of cf with 8, of ? with 7 yellow bands, the first and last ones incomplete. Forewings thinly scaled with 
yellow at base; 5 hyaline spots, that at base triangular, the others as in interrupta Willem. Hindwing hyaline, 
costal and outer margins with broadly black border projecting inwards in middle. Inner margin likewise 
black, yellow at anal angle. Forewing with white apical spot beneath. Hyaline spots rather larger in ? than 
in cf. cf 46 mm, ? 44 min. Formosa. — In the somewhat smaller subsp. flava Wilem. the hyaline portion flava. 
of the hindwings is more or less densely scaled with yellow, the 8 th abdominal band only indicated by a 
small spot, and the white apical spot on the forewings beneath absent.

S. everetti Rothsch. (11 g). Head orange, thorax black-fuscous, marked with orange; abdomen with everetti. 
transverse orange dorsal spots. Forewings hyaline, only the base, apex and the junction of the median 
nervules, as well as a dash toward the apex of the cell are black. Hindwings bordered with black. Found 
in November in Flores by Everett. 
S. cymatilis Sivinh. (= laomedia Druce) (11 h) is deep black, with steel-blue lustre; the 5 th abdominal cymatilis. 
segment is adorned by a yellow ring which in cf is only visible on the sides and beneath, whereas the back 
is uninterruptedly black. In the typical form the hyaline spots are quite insignificant, on the forewing a 
small spot near the base, one at the end of the cell, a dot below the costa and a double spot beyond the 
cell. On the hindwing only a small spot at the base. — ab. orthrus nom. nov. (= ab. 1 Hmps.) (11 h) has orthrus. 
on the forewing the spots much larger, and below the cell another good-sized spot, on the hindwing 2 hyaline 
dots instead of only one. Flies at the same time and in the same localities as typical specimens. Philippines. 
S. unifascia Hmps. (11 h) is very much like the preceding, but of more slender build; forehead white unifascia. 
and not black, hindwings broader, and the yellow abdominal band beneath does not in either sex continue 
on the back. Sikkim. 
In S. stellaris (11 h) the hyaline spots are mostly very small, but complete; it may be recognized by a stellaris. 
white ring at the base of the abdomen and on segment 5. Siam, Malacca, Sumatra and Borneo. 
S. orphana Piepers a. Snellen. Black with reddish lustre. Abdomen greenish iridescent, marked orphana. 
white as in stellaris. On forewing 3 hyaline spots, the one at the base elliptical, of the other two behind 
the middle the upper one below rib 6 is square, the lower, larger one triangular, above intersected by rib 4. 
Hindwing with elliptical median spot. Legs altogether black. Java. 
S. vandepolli Rothsch. (11 h) has the hyaline spots arranged in such a way that only one spot is vandepolli. 
placed below the middle of the cell, another, smaller one at its apex, and 3 before the apical area. Hindwings 
with two spots. Two white rings, one at the base of the abdomen interrupted upon the back, and another 
complete one on segment 5. Sumatra. 
S. longipennis Wkr. (11 h) is much larger and has the wings longer than the preceding. Below the longipennis 
cell before the middle of the outer margin, and before the apex a large tear-shaped spot; a small hyaline 
spot at the apex of the cell, on hindwing 2 other tear-shaped spots. From Borneo. 
S. albicornis Rothsch. (lli), equalling in size the former, has the spots more angular and differently aibicomis. 
arranged. May be at once recognized by the antennae being white from the middle onwards and by the large, 
pointed, double white spot on the forewing. Tonkin, found by Fruhstorfer on the Manson Mountains (3000 ft.).
