, T ^ e second insect found on the camphor plants in abun- 
dance is the Atlas moth the life history of which is‘as follows - 
The brown eggs, rather over % inch in diameter through the 
shorter axis, for they are somewhat oval in shape, are laid singly or 
in small clusters on the underside of the leaves. They hatch out into 
greyish white spined larvae which feed on the leaves and when they 
come to maturity are over three inches in length, green in colour with 
humps on the first three segments behind the head (caterpillars of 
moth and butterflies always consist of 14 segments including the head 
ut the 14th is difficult to see). On segments five to twelve there are 
transverse rows of bluish grey processes (like the arms of a small 
sea anemone but stiff) pointing backwards. On the outer side of the 
hind leg is a blue spot with a red ring round it. 
All the damage done by this insect is during this stage. 
Fiom a caterpillar it turns into a pupa encased in golden brown 
The moth spans over 8 inches across the wing and is coloured 
with various shades ofred, yellow, blue and black and has a large 
triangular window-like spot in the centre of the fore and hind wings ■ 
a number of specimens have a further glassy streak over and beyond 
.the marks on the fore wings. 
The pest can easily be dealt with by collecting the cocoons spun 
up generally in the fold of one leaf or pulling off the caterpillars, 
bhakmg is not of much use as they have a firm grip. 
Spraying with tobacco water or soap emulsion should be tried 
where the pest is bad. 
The moths are very conspicuous and may be destroyed 
especially the fat bodied females which lay over two hundred 
eggs. 
Cam P *° r , a PP ears to be °ne of the coming products of the 
Federated Malay States and of late a number of inquiries have been 
received as to its cultivation, so I hope that the above hints will be 
of use to those who wish to grow it. 
The beetle in question has also been found feeding on rubber but 
the height and stability of the frees will prevent of the possibility of 
getting rid of it by shaking. If it becomes a pest on that plant 
spraying will be the best remedy.
