senting an army of unpalatable individuals greatly exceeding in numbers the so-called 
‘ mimicking species.’ ” 1 
Another interesting Moth ( Phyllodes ) is represented in this region by several 
species, and some new ones were discovered by the Expedition which furnish links 
in a remarkable chain of modifications in 
the colouring of the wings. The posterior 
wing bears a red patch near the anal border, 
in one species a white patch appears in the 
centre of this, and then in other different 
species is observed successively nearer and 
nearer to the apex, until at length it reaches 
it. These changes are shown in the accorn- 
panying cut. 
It may be noticed that as the white 
emerges from the red it seems to give off 
atoms in advance, so that the apical patch 
becomes gradually larger and whiter from its 
commencement in Phyllodes Jlorcdis. For 
this alteration in the position of colour- 
patches Dr. Leuthner proposes the term 
“ chromatropy.” Such cases show how im- 
portant it is to describe all the local forms 
which are known to be constant, since only 
by this means will it be possible to discover the laws which regulate the disposition of 
the colours and markings on the Lepidoptera. 2 
Numerous dealers brought trays of the shells, for which Amboina is famous, to the 
ship, but the prices asked were so high, that it would probably pay to bring some of the 
shells back again from Europe to Amboina for sale to passing visitors. Cassowaries’ eggs 
were also offered for sale, and large quantities of horns of the Deer (Rusa moluccehsis). 
The deer are very abundant in Amboina, and a party from the ship went in pursuit 
of them. They had a letter to a native head-man in one of the villages on the 
shores of the inlet in which the harbour lies, who treated them hospitably, and 
collected about a dozen beaters. The deer were lying down concealed on a plain of 
some extent close to the shore, covered with tall grass in some places about 3 feet 
high, and skirted by bushes. A stag and two hinds were seen to make off out of 
range, as the party made its way along the edge of the tall grass. The men beat the 
bushes at the edges of the grass, and at last drove a hind out of one clump to the

margin, slightly suffused with white in some examples.

2. Phyllodes consobrina, Westw., the red patch more rounded, of 
a more crimson tint, with a conspicuous snow-white centre. 
Silhet. 
3. Phyllodes cerasifera, Butler, the red patch considerably larger, 
the white patch within it also larger, extending nearly to 
the inner edge of its red zone. Philippines. 
4. Phyllodes floralis, Butler, the red patch only extend- 
ing half-way round the white patch, which is rounded and 
very large. Borneo. 
5. Phyllodes verhuellu, Vollenh. , the red patch still more abbre- 
viated, so as only to encircle one-third of the white patch. 
Java. 
6. Phyllodes conspicillator, Cramer, the red patch dark elon- 
gated, not suffused with or interrupted by white ; the apex 
broadly ash-grey or white. Amboina.
