Through the kindness of Professor E. O. Essig, of the University of California, I have been enabled to examine a collection of Coccidae from Formosa, made by M. Maki and S. Inamura, and also a small amount of material from Foochow, China, collected by Mr. C. R. Kellogg. It is upon this material that the present paper is for the most part based. In addition to this, I am taking advantage of the opportunity to rectify certain errors that have been made in the identification of a few species from Japan.
