408 Mr. L. Guppy, Junr., on 
a period of nearly six weeks, of which two are in the pupa 
state. 
The imago as a rule emerges during the night or early 
morning. 
HABITS OF THE LARVA. 
They are solitary, and consume cast-off skin after each 
moult, which takes place generally during the night or 
early morning. 
They feed as a rule from the underside of a leaf, more 
often by eating a hole somewhere near the centre, and are 
very active, dropping immediately on being alarmed, 
suspended by a silken thread, and they remain suspended 
until the alarm is over, when they swarm up again 
quickly. To get from one place to another, if they discover 
any obstacle to their movements, or that their position is 
not satisfactory, they cast themselves off after making fast 
by a silken thread, and lower themselves until an object 
is reached from which it is possible to explore further. 
HABITS OF THE IMAGO. 
I am of opinion that although this moth may be seen 
here throughout the year, its real home is in the forests of 
Venezuela, from whence it migrates here annually, more 
or less according to favourable seasons, during the months 
of July, August and September; a few females here and 
there, however, do deposit their eggs in an erratic manner 
in favourable places in Trinidad, but the majority return 
to the continent. 
In the spot where I discovered their larvee, judging by 
the appearance of the creepers they were found on, there 
could not have been many of the larve about, as, though 
there were leaves slightly eaten here and there, there was 
nothing to draw attention to the fact that there were any 
larvee of such a plentiful insect as C. leilus, especially when 
one considered the immense numbers that appeared in the 
year I made this discovery. 
I am indebted to Mr. Edgell Johnstone, of Messrs. 
Tennants’ Agency, San Fernando, for the following informa- 
tion in connection with their movements in the southern 
parts of this island :— 
“ As far as my observation of the ‘Green Page’ moth 
(local name of C’ /eilus) is concerned, I noticed them flying
