 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.
