SYMBRENTHIA. By H. Fruhstorfer. 
differing in the from all the other Moluccan forms in the broad yellow, club-shaped spot on the forewing; 
ground-colour of the under surface quite pale; 2 $$ which belong also to this form, deviate from Obi specimens in 
the broader black patches on the upper surface. The ( Jd' of the rainy-season form differ but slightly from those found 
in Buru, in the smaller red-brown subapical dots on the forewings. In the Spice, Key and Aru Islands the ge- 
hylaeus. nus Symbrenthia is not represented, being only met with again in New Guinea: hylaeus Wall. (121 d) is a highly 
specialized form, lacking on the hindwing the black median band. It was described from Dorey, and I pos- 
hippocraies. sess quite a series collected by Doherty in Kapaur and the Arfak Mts. in Dutch New Guinea. -—- hippocrates 
Stgr. from Kaiser-Wilhelmsland, discovered by Wahnes on Astrolabe Bay, and reported as a great rarity from 
ciita. Simbang by Hagen, is not represented in my collection. — atta Frulnst. a distinct local form from the d’Entre- 
casteaux Islands, representing a transition from the western forms to the highly differentiated hylaeus Wall. 
Both wings have the outer border just as unusually broad as in hylaeus, but the hindwing still contains the black 
median band, which is among all the forms of hippoclus only missing in hylaeus. In addition the black 
band below the cell of the forewing is very broad and jet-black, and the black basal and costal bands on the 
hinclwing are at least twice as broad as in hylaeus. The ground-colour is a rather uniform light yellow-brown, 
lacking the whitish and red-brown irroration peculiar to hylaeus. On the under surface atta resembles the con¬ 
tinental forms in every way but the dark violet, very narrow, subanal streak forming the inner border of the 
armis. caudate appendage. Fergusson, type, $, forewing measuring 25 mm in length. — armis subsp. nov. is an inter¬ 
mediate form between hippoclus Cr. from the Moluccas and hylaeus Wall, from New Guinea, in as much as the 
black median bands on the hindwings are not so completely obliterated as in the latter. Neu-Pommern, very 
scarce. 
ptatena. S. platena Stgr. is confined to Celebes and has only been observed so far in the Minahassa. In size 
like hippoclus clausus Fruhst., but the tail on the hindwing is longer. On the forewing the yellow subanal 
band is drawn out to a point both in front and behind. The black median band on the hindwing is steeper. 
Beneath it is marked with two wedge-shaped, whitish-violet patches in the cell and between the furcation of 
the medians. The forewings are of a richer red-brown colour mottled with violet; also the hindwings are at the 
base deeper brown, but have the distal half paler and more faded than in clausus. Possibly plateni is after 
all only an Alpine and seasonal form of hippoclus clausus of the lower plains. 
S. hypselis. This collective species is, in contradistinction to S. hippoclus, limited to the Indo-Macro- 
malayan Region; the seasonal forms are less sharply separated, and there is only one $-form known which 
resembles the but none which is heteromorphic. hypselis is more scarce than hippoclus, only in Sikkim it 
is counted as the most common Symbrenthia. It has never been observed to ascend to more than 3000—-4500 ft., 
sinica. and is not found in southern India or Ceylon. — sinica Moore (Vol. 1 , p. 211) from western China is the most 
cotanda. northern form known. —• cotanda Moore (Vol. 1, p. 211, pi. 61 e) based upon specimens of the dry-season from 
Sikkim, which differ from our figure in that on the hindwing the median band is much narrower, sometimes 
disappearing even completely toward the base and leaving the yellow-brown basal area quite uninterrupted. 
The under surface is of a faded, pale yellow tone, marked with light green in the submarginal zone of the hind¬ 
wing. The imagines are generally seen flying about the rocks in the narrow gorges formed by the mountain- 
streams, and alighting on overhanging branches. From Cashmere and the Kumaon Himalaya to Nepal and 
assama. Sikkim. -— assama Fruhst. replaces cotanda in the eastern Himalayas, extending probably as far as Burmah. 
lilaea. — - lilaea Flew, is a melanotic aberration of the preceding form, having the hindwings almost completely 
obscured with fuscous, with faded, diffuse and shadowy markings on the under surface. Hewitson mentions 
the East Indies as its home. In the forewing is 25 mm in length against 22 mm in cotanda. The ground¬ 
colour is a darker orange, all the black bands are much broader. In the colouring of the under surface it resem¬ 
bles much more the typical hypselis, but has the discal spots on the forewing dark yellow instead of red-brown. 
The type was founded on $ and $ of the rainy-season; also the dry-season form is in both sexes larger and 
sinis. darker than specimens of cotanda from Sikkim, sinis Nicev. refers to the form from the Karen Hills, Tenasserim 
and the Malay Peninsula. The author based his figure upon a specimen of the intermediate form, with paler 
under surface than either assama or circesia from Sumatra (which latter passed formerly under the name of 
circesia. sinis). — circesia subsp. nov. resembles above hypselis (121 d) from western Java, but has on the hindwing the 
black median band broader towards the anal angle, and the yellow subapical spot on the forewing more 
elongate. The under surface is more extensively marked with fulvous, the submarginal macular band rather 
yellow than blue-green. Altogether the black spotting on the under surface is more pronounced than in 
assama and hypselis. Of the ? we know two forms, one from western Sumatra with broad bands on the upper 
surface, the other from the Battak Mountains in the north-eastern part of the island, having the bands more 
frayed-out and narrower, like redesilla. Hagen reports that circesia is limited to the table-land of Toba and Karo, 
ottilia. and to the mountains between Palembang and Benkulen. — ottMva. Fruhst., an insular form distinguished by the 
broad, deep ochre-yellow irroration on the under surface and the small blue eye-spots on the hindwings; the 
forewing has on the upper surface the fulvous subcostal patch still larger, and this patch as well as all the trans- 
hypselis. verse bands more cut-up than in circesia. Island of Nias, scarce. — hypselis Godt. (121 cl), the best known sub-
