Notes: Woodworth, C.W. 1903 Key to the Coccidae of California Published by the Author, Berkeley, California, 41 pp. Transcript of Introduction to the book The Scale insects of this State have received a great deal of attention particularly along economic lines. This is the first attempt at making a synopsis for the recognition of our species. The form of the synopsis and of the references is uniform with the author's Key to Orthoptera, in which full explanations will be found. The study of these insects requires ability to use the compound microscope and considerable microscopic tech- nique. A laboratory guide for the study of scale insects is being prepared for publication for the use of those who may wish to take up the subject by themselves and desire a detailed description of the study methods. The most useful books on scale insects are Newstead's Monograph of the British Coccidae, which contains the fullest general account of these insects, and Fernald's Catalogue of the Coccidae of the World, which is the best guide to the literature. For references to the literature of the local fauna, the present work will be found useful. The author hopes that this key will stimulate many entomologists on this coast to collect and study in this group. C. W. WOODWORTH. University of California, October, 1903.
