Habits of certain Bornean Butterflies. 213 
innumerable are the shapes, markings, and fractures of dead 
leaves that but a very sketchy likeness to a good, well-pre- 
served, dead leaf is sure to appear perfectly natural in the 
jungle. 
Our Borneo butterflies are proof against the seductions of 
sugar, even when flavoured with square-faced gin. We often 
tried to tempt them, but they took no notice, and we never 
had any chewed sugar-cane, which Mr. Pryer says they like. 
Even the bees generally despised our sugar, though they would 
come in swarms to our dried salt fish and even to plain salt. 
This love of salt was shared in a modified degree by butter- 
flies of the genera Papilio, Catopsilia, Charaxes, and others, 
chiefly whites. The Papilios were of the sarpedon types, and 
I never saw the dark memnon types touch it. When camped 
on a stream our dyaks always took their fish to soak and wash 
in the running water before cooking it; and the spots where 
the fish were laid on the sand were often perfectly smothered 
with butterflies. They showed no fear and would come while 
the dyaks were at work. Curetis will often settle on the salt 
fish when it is drying, and be so intent on feeding that it can 
be picked up. Generally these salt-resorts were smothered 
with the following species :— 
Papilio sarpedon. Most common. 
agamemnon. Common. 
evemon. Less common. 
mecisteus. Fairly common. 
telephus. Fairly common. 
bathycles. Fairly common, 
arcyles, Less common. 
Hebomova P Rare. 
Catopsilia crocale, Common, 
Of the Papilios, arcyles and agamemnon are the most rest- 
less and stay but a short time in one place. The contrast 
between their sluggish movements when drinking and their 
swift ordinary flight is very great. 
The different species of Yerias, though fond of drinking in 
groups, did not mix with the above species, nor did Charazes. 
Ornithoptera Brookeana is a rare butterfly in this part of 
Borneo ; but [I have seen it in several parts of the interior of 
the Darvel Bay peninsula. Once in the mountain region of 
the head-waters of the River Segama I saw a pair hovering 
about an orange-blossomed tree and watched them courting 
for twenty minutes. ‘The male was sipping the flowers, 
vibrating its wings rapidly like a hawk-moth, the vivid green 
markings flashing out as the sun played on them. Then the
