This exceedingly interesting family, which includes the insects commonly known as " Plant Lice," is so abundantly represented everywhere, tliat some of its forms must be familiar to all our readers. one must have noticed the green Aphides which swarm upon roses, and the Ijlack ones of the boan, whilst a host of other species, more or less resembling these, are to be found upon almost every plant in the garden or the field.
