under surface is like the upper, except that the basal area of the forewing is somewhat lighter and the 
veins of the hindwing are accompanied in most specimens by streaks of feebly glossy black-brown, modified 
scales. Valve strikingly pointed, almost snout-shaped, uncus elongate-cylindrical, covered with scars bearing 
long bristles. Dorey, probably also other localities of Geelvink Bay. — decipiens Btlr., which occurs very 
commonly on the Solomon Islands, I regard as certainly belonging to mytilene on account of the light 
brown areas on the upperside of both wings; it is smaller and bears in the disc of the hindwing, especially 
on the under surface, large oblong, mostly rectangular white spots. Moreover, the proximal row of sub- 
marginal patches is more sharply marked, whilst the outer row is composed of small white dots. Uncus 
relatively short, distally sloping, valve with snout-shaped tip. 
D. ferruginea Btlr. appears to replace mytilene in British New Guinea. Ground-colour uniform dark 
brown without light patches, the subapical white oblique band similar to that of molyssa (77 e), only still 
more pronounced. Veins of the hindwing beneath nearly always without scent-stripes. Milne Bay. - 
kiriwina Fruhst. (77 e) has again very small, isolated white subapical patches. Also the marginal dots of 
the hindwing are much reduced. Both wings are somewhat lighter in the distal part of the disc, but do 
not show the glossy areas of mytilene. Under surface even lighter than above, the basal half of both 
wings washed-out, reddish yellow-brown. Cell of the hindwing surrounded by small white patches. Sub- 
marginal dotting more delicate than in ferruginea and mytilene. Kiriwina. Valve shorter without distinct 
distal beak-shaped prolongation. Uncus more uniform, without dorsal slope. — fergussonia Fruhst. Both 
sexes larger than the preceding and ferruginea Btlr., the subapical row of spots consists of rather large, 
white oblong spots, which reach approximately the size of the corresponding patches in ferruginea. The 
ground-colour is even considerably lighter than in kiriwina, moreover the circumcellular spots in the disc 
of the hindwing, which show through distinctly from beneath, are larger and more numerous. Under sur¬ 
face of the wings paler, which is especially noticeable in the basal area of the forewing. The veins of the 
hindwing surrounded by more extended and lighter grey scent-rays than in kiriwina. Fergusson, D’Entre¬ 
casteaux Island. — pittakus Fruhst. Lighter brown than mytilene and ferruginea, but without the discal 
pale tone peculiar to fergussonia. The white subapical spots are more isolated. The submarginal white dots 
more prominent than in the other races of mytilene and more elongate. Locality unknown, probably 
islands in Geelvink Bay. — jobiensis Gr.-Sm. very nearly approaches pittakus, the white subapical band of 
the forewing is composed of smaller oblong patches and the veins of the hindwing are covered with broad 
stripes of androconia. Islands of Jobi and Boon, in Geelvink Bay. — adustus Godm. & Salv., described 
from New Mecklenburg, I think should also be included here. Like decipiens of small size, with strongly 
rounded forewing, the pale brown ground-colour approximates closely to kiriwina. The subapical patches 
of the forewing are reduced to dots and the hindwing bears only beneath small white circumcellular patches. 
Common everywhere in the Bismarck Archipelago. — biseriata Btlr., from New Lauenburg, is scarcely 
distinguishable from adustus, which was described four years earlier. According to the $ before me it 
appears to be a dark brown dwarf form. — insolata Btlr. is a race from the Solomons, described without 
more exact locality in a book of travels, and bears somewhat more distinct white spots than adustus. 
D. affinis and its allies form a group in which the streaks of androconia or otherwise modified 
scales do not directly accompany the veins, but are partially separated from them by white streaks. 
Valve in the Australian races with somewhat more obtuse tip than in the superficially much modified west 
Malayan subspecies. Uncus extremely delicate, palpi-like, ornamented with fine cilia. The name-type comes 
from Australia. Altough affinis occurs from the Solomons to Java and the Malay Peninsula, from the 
Philippines to Bonerate, thus covering a wider range than plexippus L. and with the exception of the 
Moluccas, where it is wanting, flies everywhere together with plexippus, some authors cling to the idea that 
affinis is only a „variety“ of plexippus. affinis is doubtless one of the few species which have migrated 
westwards from Australia and spread as far as the Malay Peninsula. — cometto Godm. & Salv. is a form 
from the Solomons; I found the name in the British Museum, but have not hitherto been able to trace 
its source. — affinis F., the name-typical subspecies, inhabits tropical Australia, the Aru, Key and neigh¬ 
bouring islands and is also in my collection from Banda and Goram. distinguished from the figured 
affinoides-<$ (77 d) by the absence of the white cell-streak in the forewing and the paler white submarginal 
dots on the upperside of the hindwing. In the $$ the white area of the hindwing is somewhat broader. 
On the Aru Islands and also in the affinis- race from West Dutch New Guinea melaiiotic examples also 
occur, though very rarely, f. vorkeinus Bob. (named from Vorkein, a place on Aru), in which the white 
areas of both wings are densely dusted with black and the one placed between the medians of the fore¬ 
wing below the cell almost entirely suppressed. — galacterion Fruhst. On the Fergusson Islands affinis is 
modified by having the white subapical macular band of the forewing and the circumcellular patches of 
the hindwing more extended. Under surface: the white in the middle of the forewing begins to be covered 
with reddish scales and the submarginal wedge-spots of the hindwing are red-brown instead of yellowish as 
in affinis. Hence we find in galacterion lighter and more extended white markings on the upperside to-
