Distinguishing characters, especially genitalia, are given for the following vectors:

Helochera delta Oman

Carneocephala fulgida Nottingham

Draeculacephala minerva Ball

Neokolla circellata (Baker)

Neokolla confluens var. pacifica n. var.

Neokolla severini DeLong

Pagaronia confusa Oman

Pagaronia 13-punctata Ball

Pagaronia triunata Ball

Priscenus friscanus (Ball)

Differences in genitalia distinguish Neokolla confluens var. pacifica from N. confluens. All ten vectors occur in California; several of them have been reported only from this state. The usual food plants of most of them are grasses, though some have been collected on Vinca spp., some on various weeds, and Neokolla circellata on grapevine and other woody plants.
