This brood assembles in groups, on the un- 
der side of the larger leaves, about the latter end 
of April, when they form fine delicate webs, no 
doubt designed for a protection to their progeny. 
They deposit their eggs, and shortly after die. 
At first the eggs are quite round, and of a clear 
light colour, and afterwards change to a reddish 
brown. They will, if the weather proves favour- 
able, be hatched in about ten days after they are 
quitted by the parent. From this period, through 
the summer months, there will be several genera- 
tions, and always a mixture of egg’s and living 
animals, till the latter brood emerge from the ova, 
about the fore end or middle of September, and 
remain on the tree a few weeks after, providing 
the weather proves fine. About the middle of 
October they will principally have left the tree, 
or sometimes before, should the weather become 
cold and wet, at which period there appear to be 
no eggs left unhatched. 
The Spider’s I’etirement through the incle- 
ment months is principally in nail-holes, crevices of 
the wall, and shreds which are used in training 
the tree, and in the earth, close to the walls, &c., 
where they remain torpid till they are animated 
by M'arm weather in February or March : at all 
events they are always roused from their sleep by 
the time the tree affords them the least portion of 
provisions or food. From the tree being thus so early 
infested it is materially injured. These insects feed 
on the buds as tlioy break forth, and then prin-
