Phytoseiid mites are beneficial to agriculture because they often prey upon phytophagous mites. This publication provides keys, descriptions, and illustrations for the recognition of 52 California species of phytoseiids and hitherto unpublished data on their distribution and habitats. It gives general information on collecting and preparation of specimens.

The following new species are described:

TYPHLODROMINI—Metaseiulus pinnatus, M. pomoides.

AMBLYSEIINI—Amblyseius lecanis, A. chorites, A. ablusus, A. lindquisti, A. inornatus, A. loxus, A. kennetti, A. vallis, A. mckenziei, A. huffakeri, A. scyphus, A. tabis.
