Huebner was the first to picture the Alpine $, which may therefore be named hippocla Hbn. All the $$ found hippocla. 
from the plains up to about 2000 ft. resemble the in the yellow bands. As I have such yellow $$ only from 
the Zuidergebergde in eastern Java, lam unable to state whether they deviate in any way from those found in 
the western part of the island. At any rate the white $$ described by Godart are quite abundant both in the 
eastern and western parts of the island at elevations exceeding 2500 ft. Those from the east have the white 
bands somewhat broader, and are invariably rather smaller than those found at the Volcano Gede. — balinus balinus. 
Fruhst. is closely allied to the East-Javanese form; but with somewhat larger yellow spots, $ smaller and having 
on the forewing the white transcellular patches greatly reduced; the under surface is in both sexes more variegated

in two seasonal forms: In the of the dry-season the yellow median band on the forewing coalesces with the 
cellular spot; the $$ recall those of hippocla from Java, having like these the white bands peripherically not 
bordered with reddish. The under surface is mainly white, distally laved with yellowish. The of the rainy- 
season resemble the ordinary Javanese <33 ; but the have the bands narrower, bordered with reddish, and on the 
under surface broadly marbled with brown-violet.—■ illustrata form. nov. found from the coast (Ekas,May) up to illustrate.

water the flower-covered table-land. — sumbawensis Fruhst. (121 e). The 3 has on the forewing the black bands sumbawen-

southern Celebes, distinguished, like nearly all the other species from that island, by its gigantic size, with larger 
bands than are found in its allies from India and the Sunda Islands; moreover it has on the hindwing the costal 
spot broader and coalescing with "the median band. ■— clausus Fruhst. is the form from the lowlands in North- clausus. 
Celebes, differing from the southern Alpine form confluens Fruhst. in its smaller size and the narrower, more 
deeply constricted, black bands. The forewing has the red-brown subapical spot broader than in confluens, 
and tapering but imperceptibly toward the costa. The under surface is darker, the brown net-like markings more 
distinct. Menado, northern Celebes; specimens from Bangkai are almost identical. — centho Fruhst., distin- centho.

narrower than in the specimens from northern Celebes, being composed of two isolated spots. The under 
surface is considerably darker than in clausus and confluens from northern and southern Celebes. Sula Mangoli. 
— obianus Fruhst. differs in the 3 from specimens from Batjan, Buru and Amboina in that the black bands obianus. 
on the upper surface are greatly reduced, in consequence of which the red-brown ground-colour predominates 
to such an extent that especially the oblique median band is greatly diminished and between the upper and middle 
medians quite interrupted. The forewing has the fulvous or reddish-brown subapical band nearly twice as broad as 
in hippoclus from Amboina. The colour of the underside is lighter, the bands narrower; the subanal spot less 
broad and paler blue, the postcliscal, submarginal, cuneiform spots are pale violet, much broader than in specimens 
from Batjan and Buru, which have those spots dark blue-violet. Specimens from Obi are larger than those 
from the northern and southern Moluccas, the forewing measuring 25 mm in length. The 9 is very much like 
the 3, but has the wings more rounded and the ground-colour lighter; the black markings are still more reduced 
than in the 3 and, especially at the base of both wings, nearly entirely obsolescent. In this it differs also from 
hippoclus -$$ from Amboina, which have the basal area of both wings distinctly spotted with deep black. On 
the hindwings the yellow submarginal band is darker and narrower than in Aynboina-^, beneath the 
helmet-shaped spots at the anal angle are dark violet, instead of white as appears from Cramer’s figure and

from Amboina and obianus -$ in having the black median bands on the upper surface of the hindwings 
broader, the under surface lighter yellow than in obianus, but more copiously marbled with deep red-brown.

than to hippoclus horn, the neighbouring island of Amboina, or from Obi*) which is situated between Batjan and 
Buru. It is distinguished from batjana by its larger size and the broader red-brown and narrower black 
bands. The under surface has a faded appearance, with more obsolete and paler, net-like markings; on the hind¬ 
wings the subanal, helmet-shaped spots are pale gray-violet and much broader, but the blue lunule before the 
tip of the tail is very much narrower. From Buru. —- hippoclus Or. from Amboina and Ceram, where it is hippoclus 
very scarce. Cramer’s type was a dry-season form, resembling the September specimens in my collection, 
*) A similar case was pointed out by me in “Sitzungsberichte Berl. E. Verein” in 1904, in connection with an 
Ideopsis, of which Batjan and Buru have some forms in common that can hardly be separated, whereas the interjacent 
Island of Obi is inhabited by a highly differentiated subspecies.
