selango- on the upperside of the hindwing and have been named selangoranus by Fruhstoefer. — hamela Growl., 
liamela. f rom Hainan, has in the no submarginal spots on the hindwing above, the discal band is formed as in 
mahadeva, but the distal margin has a distinctly projecting tooth at the 3. radial. The brown §, of which 
there is a specimen in the Tring Museum, has on the forewing as in mehala a row of submarginal spots, 
of which the anterior ones are the largest; on the hindwing the discal spots are almost entirely absent above 
formosanus. and beneath and the suhmarginal spots are small. — In formosanus Rothsch. (= gotonis Mats.) the sexes 
are similar. The agrees to a great extent with the castor ; on the upper surface of the hindwing are 4 
yellowish white patches, which are smaller than in castor, the submarginal spots are wanting above, and 
only the anterior ones are developed beneath. In the paler $ the hindwing usually has small submarginal 
spots and between the large discal patches and the abdominal margin 3 more spots are indicated. Both 
sexes have a distinctly projecting tooth at the 3. radial. Formosa, in the hills. — The larva of P. castor 
is not yet known. The butterflies drink on moist sand and come after the refuse from the houses of the set¬ 
tlers. When frightened away they soon come back again. Their flight is low and feeble. 
If a linear arrangement according to relationship were possible we should continue with P. canopus. 
AVe insert here some Papuan forms which are mimics of Uranids and Acraeids. 
Laglaizei Group. 
Upper surface of the wings blue-black, with grey-blue median band and on the forewing in addition a - 
narrow grey-blue subapical band, the bands not metallic; the short-tailed hindwing beneath with orange-coloured 
patch behind the base of the lower median. The subcostal and lower median of the hindwing branching off far 
from the base, much as in the agestor group; antennae short as in that group; the genitalia likewise recall the 
agestor group. 
laglaizei. P. laglaizei Depuis. (= alcidinus Btlr.) (38 c). the median band of both Avings broad, the tail 
and usually also the adjoining part of the distal margin grey-blue; the under surface for the most part 
blue-grey, the hindwing in fresh specimens bluish grey Avith a faint yellowish tone. The individual mark¬ 
ings very \ T ariable in specimens from the same district; the black spots on the disc of the hindAving beneath 
often much enlarged and the proximal patches confluent Avith the corresponding distal ones. A $ from 
Astrolabe Bay Avith narroAv blue instead of blue-grey median band and blue under surface Avas described 
wahnesi. by Bober as a distinct species; I consider the specimen an aberration: ab. wahnesi Rob. — The area of distri¬ 
bution of laglaizei embraces the Aru Islands, Waigeu and the whole of New Guinea. The butterfly is in general 
rare, yet the Tring Museum once obtained a collection from Dutch New Guinea, made by natives or Malays, 
which contaiired about 100 specimens of this species. According to A. S. Meek laglaizei is also no rarity 
at the south-east extremity of British New Guinea, not even at the coast. The resemblance to Alcidis 
agathyrsus is surprisingly faithful on the upper surface; the under surface differs considerably from that 
Oi the model, but bears a usually very conspicuous orange spot which corresponds to the orange-coloured 
underside of the abdomen of Alcidis. The two butterflies fly together round the tops of trees, but the Uranid 
is much commoner than the Papilio. C. Wahnes has bred the butterfly more than once and has sent several 
blown larvae to the Tring Museum. These are black; on each segment a broad yellowish red girth, in which 
as well as in the black belts light yelloAV dots are placed; at each side of the back a roAV of short black 
spines, which are placed on large round black dots, at the dorsal side of which is a yellow dot; the last seg¬ 
ment for the most part black; head black; scent-fork (in the inflated specimens) yellowish grey. Food- 
plant not recorded, probably Citrus. Herr Ribbe, without giving any characterisation (!), has proposed the 
names mukaensis for specimens from Waigeu and maraganus for the ,,New Guinea form“; such nomina nuda 
have naturally no right of priority, should the specimens from the localities mentioned really be different 
and therefore have to he named. 
toboroi. P. toboroi Ribbe (38 c). Whilst in laglaizei almost the Avhole upper surface of the body and also the 
sides of the abdomen are blue-grey, toboroi has an entirely black body without any markings. Upper sur¬ 
face of the wings dark blue, with a slight oily gloss; the median band of both Avings narrow, the part placed 
in the cell of the forewing is commonly diffuse and is always at a distance from the apex of the cell; on the 
hindAving a pale yellow anal spot, the tail entirely black-blue. The under surface in contrast to laglaizei 
for the most part black; in the forewing a submarginal band, which is anteriorly broad and greyish yelloAV, 
posteriorly narrow and bluish, and before the middle a more or less indistinct narrow blue band; on the hind¬ 
Aving a large basal area and a broad submarginal band are grey-yellow, and the black central area is more 
or less broken up into large patches, the orange-coloured spot before the hindmargin paler than in laglaizei. 
The $ as in laglaizei quite similar to the G; on the upper surface of the hindwing it has from the 3. radial 
backwards an irregular narrow grey-blue submarginal band, which in the G is only indicated. — Bougainville,
