EXSULA. By Dr. K. Jordan. 
niveifas- S. niveifasciata Roths. (2e). Only one $ known. Similar to the $ of S. vacillans taeniata, but 
data. t ] ie f or ewing without the short onter band. Besides the palpi, coxae and legs also the underside of 
the abdomen clothed with yellow scales and hairs. •— Borneo, without more exact indication of locality. 
scmperi. S. semperi Feld. (4 a). Black, basal half of palpi, fore coxae, and underside of femora and 
tibia of fore leg orange. Forewing with a straight orange median band from the costa to the hind 
angle, which it does not quite reach, the band beneath anteriorly widened and enclosing a large black 
discocellular spot. Hindwing above with strong blue gloss, the fringes being white. — Philippines: 
Luzon, Mindanao; only a few specimens in collections. 
S. albomarginata. Black, with metallic blue gloss. In the <$ the markings on head and pronotum 
orange, also the palpi, coxae and legs, underside of abdomen and the edges of the claspers more or 
less extended orange; in the 9 the markings of the head white, segments 1 and 2 of palpi yellowish, 
the fore coxae and underside of the femora and tibiae of the fore legs orange. The fringes of both 
wings entirely white or yellowish, sometimes this colour extending on. to the wing. Forewing of $ 
with small white spots, which are often absent above, viz., an often tripartite cell-spot, a spot below 
the cell and a row of 3 or 4 between cell and apex of wing; in the $ these markings are only present 
dlbomargi- beneath or some of them are entirely obsolete. Andamans, Burma, Annam, Philippines. — albomar- 
na,a - ginata Moore (2 c). The white marginal border to the forewing narrow. <$ usually with white spots on 
opheltes. the upperside of the forewing. Andamans. — opheltes Druce (= candidemarginata Pouj.). The white 
border more or less widened; upperside of forewing of <$ usually without white spots. Burma, Te- 
flaviciliata. nasserim, Annam. This and the preceding form entirely intergrade. - flaviciliata Bdv. ( = fimbriata Bdv.). 
Fringes of both wings yellowish. Upper median branch in forewing farther away from the apex of 
the cell than in the previous forms, originating almost in the centre between third radial and lower 
median. Philippines: in Mus. Tring 1 $ from Luzon, collected in January by A. Everett. 
S. vulcania. Body above black, beneath in for the greater part orange like the prono¬ 
tum, hind edge of the head, sides of frons, and palpi; in $ only segments 1 and 2 of palpi, fore coxae, 
underside of femora and tibiae of fore legs and the apex of the abdomen orange. Wings black; fore¬ 
wing similarly as in S. amatrix with a median band composed of three larger yellowish spots and a 
short discal band of four small white spots; hindwing glossy blue, with white fringes. Burma, Tenas- 
vulcania. serim and Tonkin. —- vulcania Bull. (= glossatrix Westw.) (2e). The cell-spot somewhat smaller than 
or as large as the third median spot. In $ the apex of the abdomen orange also above. Burma and 
melania. Tenasserim. — melania Joannis. $: Abdomen above entirely blue-black, beneath only orange at the ex¬ 
treme tip. Cell-spot of forewing larger than third spot of band; the white colour of the fringes of 
the hindwing not extended on to the wing. From Tonkin; in the Tring-Museum 1 £ collected by 
Fruhstorfer at Chiem-Hoa in August or September. 
4. Genus: £xsu8ii Jord. 
Frons convex, the process feebly indicated. Eyes naked. Antennae somewhat dilated distally. 
Segments 1 and 2 of palpi with rough hair, 3 slightly clavate, smooth. Tibiae and tarsi smoothly 
scaled; claws symmetrical in both sexes, short, with strong tooth; tarsal segments 3 and 4 beneath 
very densely spinose. Forewing with areole, subcostal 2 originating far beyond areole and 3 near the 
areole or at its apex, cross-vein deeply incurved, upper median near lower angle of cell, lower median 
far proximal, cross-vein of hindwing not oblique, feebly incurved twice or anteriorly straight, radial 2 
(= vein 5) before centre of cell. Early stages not known. — North India and Burma to Formosa; 
two species, which have both a rather strong blue gloss. 
E. dentatrix. Collar, abdomen and fore coxae orange-yellow, abdomen with black rings. Fore¬ 
wing with two larger antemedian and three smaller discal spots and frequently a subbasal cell-spot. 
Hindwing with a black median band which is posteriorly abbreviated and clavate, distally produced 
into two teeth, and costally united with the costal border; distal margin broadly black, with a more 
dentatrix. or less distinct blue or violet gloss. North India to Formosa. — dentatrix Westiv. (le). Forewing with¬ 
out a yellowish or whitish subbasal cell-spot, or this spot very small; the yellow area of the hind- 
wing extends costally not (or rarely) to the costal vein, and the portion situated in front of the 
subcostal is hardly paler on the underside than the disc. The spots of the forewing are either 
all yellowish, or all white, or the proximal ones yellowish and the distal ones white. The proximal 
conjuncta. spots are either united, forming a band: f. conjuncta form, nov., or separated: f. dentatrix vera. 
albomacu- Nepal, Sikkim and Assam; abundant. — albomaculata Myiake, described from Formosa, is also before me 
lain. f rom Central Tonkin. Subbasal cell-spot of forewing always present also on the upperside, being here 
about as large as it is on the underside of dentatrix ; the orange area of the hindwing reaches the 
costal vein and the portion placed in front of the subcostal is whitish on the underside. The spots of the 
forewing white and the proximal ones always ( ?) separated.
