Distinguishing characters, especially genitalia, are given for the following species of Cercopidae:
Apbrophora angulata Ball
Aphrophora permutata Uhler
Clastoptera brunnea Ball
Philaenus leucophthalmus (Linnaeus)
The distribution of these four species is reported and their food and breeding plants in California are listed. Distinctive markings are described and illustrated for the following six color forms of Philaenus leucophthalmus, all occurring in California: var. leucophthalmus (Linnaeus); var. pallidus (Zetterstedt); var. fabricii Van Duzee; var. marginellus (Fabricius); var. spumarius (Fallen); and var. impressus n. var.
