One new pseudococcid genus, Prorhizoecus, and 15 new species are described and illustrated in this paper. Only three of the new species were collected in California: Dysmicoccus polymeris, Pseudococcus beardsleyi, and Spilococcus nototrichus. Other new North American species were collected as follows: Trionymus strongylus, Arizona; T. idahoensis, Idaho; Cataenococcus mexicanus, Hypogeococcus othnius, Prorhizoecus atopoporus, Rhizoecus neostangei, Spilococcus villanuevai, Trionymus coronus, Mexico; and Chorizococcus coniculus, New Mexico. Four Central and South American species are described: Dysmicoccus brachydactylus and D. dactylus, Chile; Hypogeococcus othnius, Costa Rica, Guatemala, Nicaragua, and Venezuela; Mammicoccus balachowskyi, Peru.

Revised keys to North American species are given for the genera Cataenococcus, Chorizococcus, Dysmicoccus, Hypogeococcus, Pseudococcus, Rhizoecus, Spilococcus, and Trionymus. In addition, a key to the two species of Mammicoccus is presented.
