(ex) 
them into a killing-bottle, but when folding them into their 
papers afterwards I was often startled by sudden movements 
which made me hastily return them to their bottle. Nothing 
else seemed to die so hard. As I was not specially on the look- 
out for a difference in the vitality of the two species, I cannot 
be certain that there was no difference, but I am fairly sure that 
all the swallowtails required an extra dose of killing-bottle. 
“The open ground was more or less bushy and in places 
covered with a wiry white-flowering plant—sSida rhombifolia, 
L., about a foot high. This harboured all sorts of smaller 
butterflies and the swallowtails were constantly fluttering 
among them. Except round the tree they hardly ever flew 
more than shoulder-high and did not often go far out into the 
open. In the heat of the day there would be dozens on or 
near their favourite yellow tree. They were always very 
conspicuous on the wing, but so alike that I often did not 
know whether I was catching model or mimic till I had them 
dead in my hand. Seeing them now, set side by side, there is 
a much bigger difference in size than I should have expected. 
“There are a few other species to which I should like to 
draw attention, all but two caught on the same open waste. 
“i. Two specimens of Papilio polydamas polydamas, L. 
(Section I), caught on January 31 and February 6. One 
specimen of their mimic, Papilio scamander grayi, Boisd. 
(Section IT, viz. ‘ Fluted Swallowtails,’ Roths. and Jord., or 
‘Papilio Swallowtails,’ Haase), caught on February 7. Two 
specimens of another mimetic swallowtail, belonging to the 
same Section II, Papilio anchisiades capys, Hiibn., the male 
on February 8, in the hotel garden, the female on February 4, 
on the waste. I only caught one specimen of each of the 
latter, but I saw more, chiefly frequenting the yellow tree, 
Vochysia tuscanorum. They usually flew high and were not 
nearly so numerous as P. chamissonia and P. lysithous. 
“ji. One specimen only of the Brassoline butterfly, Penetes 
pamphanis, Doubl. and Hew., which I caught on February 8, 
in the hotel garden. It was sitting on a tree-trunk with wings 
folded, and was very inconspicuous, the underside of the wings 
harmonising so well with the bark. I saw other specimens of 
this species sitting thus on trees, motionless for hours, but
