C. eubule (sex not recorded) were seen, when the sky was dull, to 
settle on the lower, yellowish leaves of Plumbago scandens, Linn., 
close to the ground. 
Mackfield, Jamaica, January 27th, 1907. I was watching the move¬ 
ments of a C, eubule , when a cloud passed over the sun; after 
fluttering about for a very short time it settled in the middle of 
a yellow, lower leaf of Bryophyllum . 
Montego Bay, Jamaica, February 4th, 1907. A $ 0. eubule was seen 
flying across the race-course. The track was carpeted with 
short grass of a rich full green, but amongst the grass were long 
trailing stems of the Ipomoea pes-caprae, Sw.; on one of these 
stems was a solitary bright-yellow leaf, far from any other of 
like colour: on this the yellow butterfly settled. 
Montego Bay, Jamaica, same day. A $ C. eubule was seen to settle 
on an isolated yellow leaf of a creeper in a hedge, about six feet 
from the ground, all the surrounding foliage being green. 
Constant Spring, Jamaica, January 4th, 1907. A dull afternoon : 
a ? Terias euterpe, Menet., was seen to settle close to a leaf of its 
own size, shape and colour. 
Same place and day. A £ T. euterpe was watched for some time 
and repeatedly disturbed; it seemed to avoid dark green foliage, 
and always settled on a low plant with yellow-green leaves. 
Mackfield, Jamaica, January 27th, 1907 ; 4.30 p.m. A specimen of 
T. euterpe seen to settle four times as follows :— 
(1) On a yellowish leaf of Bryophyllum: it was, however, but 
ill concealed thereby. 
(2) On a pale green leaf. 
(3) On a yellowish-green, finely-cut fern ( Adiantum sp.). 
(4) On a yellow-green leaf of a Convolvulus (or perhaps Ipomoea). 
In this case the concealment of the insect was remarkable. 
Same place and day. Another specimen of T. euterpe was seen to 
settle on the underside of a yellowish leaf of the Bryophyllum. 
Same place and day. A $ of T. euterpe was seen to settle three 
times :— 
(1) On a yellow leaf of Bryophyllum ; fairly cryptic. 
(2) On a light green leaf of an unknown plant, somewhat cryptic. 
(3) On a leaf of Bryophyllum less yellow than (1), the result less 
cryptic. 
Mackfield, Jamaica, January 31st, 1907. Three specimens of T. 
euterpe (sex not determined and specimens not preserved) were 
watched with the following results respectively:— 
(1) Seen to settle on a yellow leaf of Bryophyllum .
