Among the beneficial insects of California as well as elsewhere, the Coccinellidse hold high rank as aphid and scale feeders. In order to determine the relative efficiency of some of the more important forms, a study of eight of the principal aphid-feeding species of this state was made at Sacramento during the season of 1913, and completed at Berkeley and Riverside in 1914. The species under observation were: Hippodamia convergens Guer., Hippodamia ambigua Lee, Coccinella californica Mann., Coccinella trifasciata Linn., Olla oculata Fabr., Olla abdominalis Say., Cycloneda sanguinea Linn., and Adalia bipunctata Linn.
