The upper surface of the leaves growing below the places where 
clusters of these insects were located, became speckled with a white 
substance, which was usually in dots of different sizes; this being the 
honey dew ejected by the insects and falling and drying upon these 
lower leaves. And an aphis might sometimes be seen with a small 
mass of this same white substance adhering to the tip of one of its 
honey tubes, evidently formed by excreted honey dew which had 
evaporated upon the end of the tube. 
Of the immense number of lice upon this bush at this time, nearly 
all were found to be pupae, varying considerable in their size. Only 
Here and there could a small young louse be found, hid or partly hid 
under these pupae. Wingless females were rare, and were usually alone 
on the midvoin of a leaf, or with two or three young around them. 
Scattered among the pupae were winged lice, all of them newly 
hatched. It is evident that these winged individuals all leave the 
bush soon after acquiring their wings. 
As it was mostly pupae that were on the bush at this time, and 
these were flying away as fast as they obtained wings, it is probable 
that within a week the hush would have been evacuated of every¬ 
thing except the few small young lice and wingless females. But so 
thronged and overburdened with these vermin as it then was, it 
seemed to call for instant relief. I therefore prepared a basin of 
strong soap suds, and, with a sponge wetted therein, I wiped the lice 
from the under side of a multitude of the leaves. To cleanse all the 
infested leaves in this manner was a task too formidable to be 
attempted. Where I could do so, I bent the twigs and the mass of 
wrinkled leaves at their ends, downward, and immersed them in the 
solution of soap in the basin. In other instances I let a streamlet 
from the sponge fall upon the tips of the twigs and run down along 
their under sides, so as to wet all the lice that were clustered there. 
Upon examining the results of this treatment the next day, I found 
multitudes of the lice were killed thereby and were hanging to the 
twigs, suspended by their beaks inserted therein. Others had been 
dislodged by the streamlets, and were washed together in small 
masses which had lodged along the limbs. But it was only those that 
had been wetted that were killed. Many were lurking in the corru¬ 
gated leaves at the ends of the twigs to which the soap solution did 
not penetrate. From these and other places where they had remained 
dry they were now coming, and were beginning to reoccupy the washed 
twigs. I had hoped that wetting the twigs and leaves with such a 
strong solution of soap would perhaps so infuse their surfaces with
