Ill 
days to suit themselves with a residence, mostly 
on the branches, but sometimes on leaves. They 
feed through the summer months, and a little at 
the fore end of spring, during which intervals they 
adhere close to the branches and leaves, and ap- 
pear motionless. 
A scale or shell is gradually forming over the 
insects, also the legs, from the swelling of the 
abdomen, become obscure, excepting so far as they 
appear only like transparent lines on the belly. 
The Scale attains to the size of about a quarter of 
an inch across by the time she establishes her pro- 
geny, and also at this time the scale is nearly round, 
and of a brown colour. 
The males are few and small in size ; they 
ai’e furnished with wing's. Immediately after copu- 
lation the male dies, as in all other species of the 
Cocci tribe. 
It is not common for these insects to prevail 
predominantly, but when they do they prove very 
injurious to the Vine, by drawing out the sap, 
and very much dirty the stems and leaves with 
the fluid they eject, and besides this they have been 
known to disfigure the Vine as though it were 
covered with cotton. I remember an instance of 
this kind with some Vines in a gentleman’s 
hot-house, neai- Leeds; the Grapes appeared to 
be rendered useless, as well as the Vines exhibit- 
ing a dirty and disagreeable appeai'ance.
