The drumming signals of seven California stonefly species from the family Perlodidae are reported. Drumming descriptions are improved by graphing each of the signal's individual intervals (or interval pattern) and the determination of signal type (monophasic, varied beat-interval, diphasic and grouped) is based upon these graphs. Signals are described for the first time for two species: Baumanella alameda (Needham & Claassen) and Cultus pilatus (Frison). New signal characters and signals from additional locations are provided for five species: Calliperla luctuosa (Banks), Chernokrilus misnomus (Claassen), Cosumnoperla hypocrena Szczytko & Bottorff, Osobenus yakimae (Hoppe), and Rickera sorpta (Needham & Claassen).
