211 SOME COCCIDAE FROM EASTERN ASIA. By G. F. Ferris, Stanford University, California. Through the kindness of Professor E. O. Essig, of the University of Cahfornia, 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, coUected 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. The material from Formosa is especially interesting, as nothing appears to have been published concerning the Coccid fauna of that island. The majority of the species here recorded are widely-distributed forms ; a few are known from Japan ; and several are species that have heretofore been recorded only from India, Ceylon and Java. While the number of species dealt with is not sufficiently large to permit of any generalisation, there is at least a suggestion that the Coccid fauna of Formosa is more closely related to that of southern Asia than to that of Japan. The types of the new species here described are in the Stanford University Collection. Icerya seychellarum (VVestw.). On Morus alba and Citrus sp., Taihoku, Formosa. Icerya purchasi (Maskell). On Citrus sp., Taihoku, Formosa. Pseudococcus filamentosus (Ckll.). On Citrus sp., Taihoku, Formosa. Pseudococcus comstocki (Kuwana). On Citrus sp., Taihoku, Formosa. Previously recorded from Japan and the United States. Pseudococcus virgatus (Ckll.). On Baphinia sp., Ako, Formosa. Pseudococcus citri (Risso). On Morus alba, Ako, Formosa. Antonina bambusae (Maskell). On Bambusa stenostachya, Taihoku, Formosa. This is the species that has ordinarily passed under the name of Chaetococcus bambusae. I am entirely in accord with Green in the opinion that Chaetococcus cannot be maintained as distinct from Antonina. Antonina crawii (Ckll.). 1902. Eriococcus graminis (?) Maskell ; Kuwana, Proc. Calif. Acad. Sci. (3), 3 : 50. On bamboo, Taihoku, Formosa. Kuwana (ref. cited) has recorded Eriococcus graminis. Maskell, from Japan. I have at hand the specimens upon which the record was based and they prove to be nothing more than immature stages of an Antonina, without much doubt A . craie'ii.
