Title: A monograph of the jumping plant-lice
Description: The family Psyllidae, or the Jumping Plant-lice, have received comparatively little attention in the New World, especially from the systematic point of view. A relatively small number of species have been described, but no serious attempt has been made to relate the several genera represented by these species.

A complete rearrangement of the genera of Psyllidae is herein presented, with only the American genera being treated in this monograph. The American genera have been arranged in six subfamilies - Liviinae, Pauropsyllinae, Carsidarinae, Ceriacreminae, Triozinae, and Psyllinae.
Subjects: Syllidae
