The ovary is still clearly recognizable as a hollow misshapen 
process on the bottom of the gall-chamber. Of the other parts 
of the flower little remains except small filliform excrescences 
round about the ovary. In the cavity there live a number of 
orange-coloured larvae, which, when maturing, probably leave 
the gall and pupate in the ground.

A leaf-gall, caused byagall-mite. 
This gall-growth belongs to a type which, 
as far as I am aware, does not occur in 
Europe. It has been found in the tropics on a 
few varieties of Ficus and some other plants. 
On two species of Ficus, viz. Ficus ribes ') 
and Fic. lepicarpa*) it has been already de- 
scribed. Also RuzssaaMEn *) mentions a Si- 
milar gall-growth on Fic. spec. of Pulu Weh, 
near Sumatra, Fig. 4 illustrates the under- 
side of an infected leaf. The leaf-blade is 
a pale green, the young galls are rose- 
coloured so as to contrast very much 
with the normal leaves. In the case of a very 
strong infection the galls conglomerate into 
an irregular layer, the whole leaf-blade 
os | being at the same time turned downward. 
Big. A Flom futatosa Reiaw, Loe galls themselves appear like granular 
 : accumulations sometimes very small, some- 
_ times larger. They consist of irregular short excrescences of 
ie —— in the form of a callus-tissue; these growths 
_ leave openings and channels for the animals to live in.
