we name sila form. nov. Those from Ceram seem, as far as I can judge from the available material, to incline 
even in the lightest type more to Melanism than antilope from Amboina. In one ? the basal portion of both 
wings has a distinct brown-violet iridescence, in another the forewing is broadly spotted before the apex with 
white-yellow and shaded with gray-violet beyond the cell. Both the hindwing and forewing show a number of 
distinct white submarginal dots. The outline of the wings is more rounded, reminding one of pithoeka (= ? fa. 
pseudopithoeka form. nov.). —- In Burn we encounter a form which in cf displays on the upper surface almost 
invariably some yellowish-white subapical spots; this is maglovius subsp. nov., and all the cfcf, even those not 
distinguished by this yellowish colour, are remarkable for a band-shaped, light brown zone on the forewing. It 
seems curious that cfcf which above lack the apical ornamentation, represent on the under surface the type 
nivas, whereas the cfcf which do have it, have the hindwings dark coffee-brown. From the island of Buru. — In 
quinctinus subsp. nov. the yellowish transverse band on the forewing is very distinct and appears also on the under 
surface. On the hindwing the submarginal zone is mainly whitish instead of yellowish (as in antilope), recalling 
on the under surface the nivas- type peculiar to the West Malayan forms. Batjan, Obi. — typhlis subsp. nov. I 
received from Mr. v. Schoeneberg without being able to ascertain whence it came from. The white bordering 
of both wings which reminds one of Euploea eurypon Heiv., E. hopfferi Fldr., and E. assimilata Fldr ., and which 
is again met with in H. alimena heteromorpha Rob. (119 e), causes me to suppose that it may have come from 
the Key Islands. But as neither Ribbe nor Kuehn nor Pagenstecher mention antilope from Key, it is not 
impossible that this interesting aberrative form may have come from New Guinea, notwithstanding the fact that 
all the specimens I possess from there are relatively small in size and of the same brown tone as antilope. 
I have specimens from all parts of New Guinea where the collective species is very rare, but only one from 
each place, and each one exhibiting a different shade of colour; one cf from German New Guinea quite closely 
approaches the form from Batjan in the yellowish-brown apical portion of the forewing. Hagen mentions four 
brown specimens in which the outer border of the hindwing is above quite pale, and another in which also the fore¬ 
wing is affected in like manner. On the under surface the outer border of the hindwing is nearly white, only 
interrupted by the black veins. Flies from December until May. The larva which has been described in the general 
diagnosis, lives gregariously on some sort of shrub, several hundred together, and must be greatly exposed to the 
attacks by parasites, taking into consideration the scarcity of the imago. I possess a ? resembling the forma sila 
Frnhst. from Dorey, Dutch New Guinea, and another one, rather closely allied to forma pseudopithoeka , from Milne 
Bay in the British part of the island. — mela Frnhst. is inferior in size even to the forms from New Guinea. 
The cf is light brown with yellowish or even snowy white, moderately broad distal border on both wings which 
recurs also beneath. The? (119 e wrongly called a fra) is brown with a faint violet irroration and adorned (as 
all cfcf are) with a white apical spot; hindwing distally lighter, the under surface is yellowish brown. From Kiri- 
wina and Fergusson Islands. — In shortlandica Ribbe which appears to be greatly inferior in size, both wings 
are red-brown at the base, and the forewing shows a very distinct band of light ochre-vellow as in the form 
from Batjan. The hindwing is thinly dusted with yellowish in the distal half. The larva lives gregariously 
upon a low shrub. Shortlands Islands. The forms found in some localities of the Bismarck Archipelago appear 
to be closely related to shortlandica. — scopas Godin, a quite similar form from Maleyte Island, is characterized 
by a rather narrow yellowish patch on the hindwing, extending in the ? as far as the cell and accompanied 
on the forewing by a light-coloured subapical zone. — Of lutescens Btlr. I possess but one specimen from the 
Fiji Islands, somewhat larger than shortlandica; the hindwing shows, in addition to the ever present costal spot, 
two other, indistinct, yellowish-white patches between the radial veins, a design which may be purely individual. 
H. pithoeka is very closely allied to H. antilope, differing from it in the more rounded outline of both 
wings, and in cf in the absence of the white submarginal spots from the upper surface of the forewing, those found 
on the hindwing being invariably ringed with black. Beneath the two terminal rows of white crescents are obsolete, 
and the dots which are blue instead of white, are placed farther away from the outer margin and more toward 
the center of the wing; the otherwise so obstinate costal spot on the hindwing is not found here. At the same 
time pithoeka is a more constant form, considering that only two ?-forms exist and that the white apical spots 
are not found in the cfcf. Our knowledge of the larva we owe to Dr. Hagen. It rather resembles that of H. 
misippus L., only it is larger, with two ochre-yellow lateral stripes which are broadest at the head. Three insular 
forms must be registered; pithoeka Kirsch shares with II. antilope the white spots at the anterior edge of the 
cell, but is in both sexes of a darker black-brown colour above. In the cf the submarginal zone of the hindwing 
is slightly shaded with red-brown, which is not infrequently replaced by a dark golden-yellow colour (= illumi¬ 
nata form. nov. 119 d) recurring also beneath in the shape of a pale yellow patch. Occasionally this colouring 
may be accompanied by a fulvous anteterminal band on the forewing Two ?? from Finschhafen have the 
outer half of both wings gray-black, three others from Astrolabe Bay show a yellowish area of different width 
in each specimen, appearing in the most extreme ? nearly white beneath and being accompanied by a yellow¬ 
ish marginal striation at the anal angle of the forewing. The type came from Geelvink Bay; but it must be 
exceedingly rare there, being never again found by Doherty. Hagen found only six specimens at Stephansort, 
and the Fruhstorfer coll, contains 12 cfcf and 7 ?? from Astrolabe Bay. — unicolor Godin, is generally 
considered synonymous with pithoeka; but three ?? before me decidedly deserve this name on account of the 
nearly unicolorous brown ground-colour, which is but slightly relieved exteriorly by some little shading of 
gray; the white dots on the forewing are more prominent, and also beneath larger and more plainly visible.
