To those who have offered suggestions I am greatlyobliged, and whatever useful information I could obtain,no matter from what source, has been used for thebenefit of those for whom the work is intended, andthis plan will be continued until the end.

The Green Peach Aphis in its habits is much like thatof the black one, but the shape and colour of the insectsin their various stages are different (see Plate XV.). When the aphides leave the tree, which, as a rule, theydo about the end of November, or even late in December,according to seasons, locality, &c, the young and perfectinsects also congregate around the base of the roots,whilst large numbers, after perpetuating their species, dieand are either blown away or eaten by ants or birds.Ants will c
