insular character). This melanotic character commencing to show itself in australis becomes intensified in the 
form of the island of Mysole, where the lack every vestige of yellow dotting, and have the underside quite 
faintly dusted with white. On the hindwing the yellow discal spot narrower on both sides, higher than broad, and 
decolorata. more broadly sprinkled with green scales on the outside than from other localities (— decolorata Fruhst.) 
westwoodi. (121 a). — Specimens from the Aru Islands, described as westwoodi Wall, have, as far as known, in the disk 
of the forewings only some fragments of a yellowish band. The under surface, according to Wallace and from 
specimens of my collection, distinguished by the broader, pale yellow discal spots on both wings which are 
traversed by very fine nerves. The blue subanal lunules confluent and more distinct than in the other 
forms. Another form, very similar to westwoodi underneath, I possess from southern Dutch New Guinea; above 
resembling hewitsoni, with the median band contiguous, the submarginal dots absent; the under surface of 
the hindwings with conspicuous, large, pale blue lunules, confluent as in the Aru form. But it is on Humboldt 
Bay and in Kaiser Wilhelmsland, the species is best developed. This form is hewitsoni Wall. <3$ either 
with the forewings completely black, adorned with a few yellow costal and submarginal dots, or with an

not be accompanied by terminal dots. are known with altogether rf-like markings. Forewings with or 
without yellow discal dots as in adua. (121 c). Besides these we know also a larger form with slight yellow 
or white transcellular strigae and greenish squamation of the submedian vein. This may be increased to such 
an extent that almost the entire outer half of the forewings is covered with large bluish-white strigae: 
schonbergi. = fa. schonbergi Hour. Rarer are $$ in which the bands are arranged as in fa. hewitsoni (121 c), which are 
always found in connection with distinct terminal dots. — As dohertyi Sm. (121 c) a particularly lovely form 
was introduced, with white patches and streaks on the forewings and either a white or yellowish-green discal 
spots on the hindwings. That name was given to $$ from Humboldt Bay, but must be abandoned since it was 
guilelmi. already used by Holland for another form, for which reason I change it to guilelmi nom. nov., from the first 
name (William) of my courageous friend and collegue Doherty who succumbed to the African climate. Ac¬ 
cording to Hagen Prothoe australis hewitsoni are true forest-butterflies which never are found in the open, poor 
fliers and much less alert than P. franckii from Sumatra. Hagen never saw hewitsoni sit with its head downwards 
mafalda. on the bark of trees, but always on .branches and leaves of shrubs. — mafalda Fruhst. (121b) refers to the form 
from British New Guinea *). Of somewhat smaller size than the forms from Kaiser Wilhelmsland, the <$£ have 
adua. always yellow terminal points or similar discal spots (fa. adua Fruhst. 121 c). But of much greater frequency 
are with a yellow semiband on the forewings (fa. mafalda) which, however, never reaches the costal 
margin; I do not know the fa. hewitsoni from Eastern New Guinea. Of the $ we know a (J-like 
form as well as specimens with greenish-white median area extending to the cell wall, and with similar trans¬ 
cellular spots. Common on Milne Bay and on the islands of the d’Entrecasteaux and Kiriwina Groups. Spe- 
schulzi. cimens of australis are said to occur also in Neu-Pommern. — As schulzi Ribbe a form was described having 
the yellow marginal spots on the forewings widened so as to form regular bands. Neu-Lauenburg (Mioko). 
Ribbe found only a few in Neu-Pommern and Neu-Lauenburg also specimens representing the forms 
layardi. hewitsoni, schonbergi and guilelmi (= dohertyi). — layardi Godm. a. Salv. replaces australis in Neu-Mecklenburg. 
Since I do not possess such specimens, I can only judge this lovely form from Grose-Smith’s figure. 
In size it surpasses australis-hewitsoni by one third. Ground-colour dark brown. Forewing with 4 preapical 
greenish-yellow stripes, hindwings with an anally green, in front sulphur-yellow area touching the cell. Under¬ 
neath the markings of australis are repeated, without any white or yellow discal spots. 
ribhei. P. ritobei Rothsch. resembles a large schulzi Ribbe ; forewings with the submarginal spots placed close 
to the termen, and united to a longitudinal bluish-green band, on the hindwings a narrow median band 
traversing the entire length of the wing. Underside of the forewings with yellow anteterminal lunules, of the 
hindwings without any unusual discal markings. At the tail and in the interspace above the upper me- 
praesignis. dian a chrome-yellow marginal spot. From Bougainville (Solomon Islands). — praesignis subsp. nov. surpasses 
ribbei in size, being as large as layardi. Forewings distinguished by yellow, elongate spots placed far apart 
between the subcostal veins. Forewings of with 3 greenish submarginal longitudinal stripes between the 
median nervules and submedian; the $ has only two of these, one above the submedian very distinct, 
the other intramedian almost obsolete. Hindwings in both sexes traversed by a regular, compact longitudinal 
band, greenish in $> more yellowish in much narrower than in ribbei from Bougainville. Under surface as 
in ribbei , but with only 5 yellowish anteterminal spots on the forewings instead of a complete series as in ribbei. 
The white spots in the basal area on both wings diminished, in consequence of which praesignis appears to be
