G. F. FERRIS. 



Cerococcus ficoides (Green). 



On Mallotus japonica, Taihoku, Formosa. Previously known only from the 

 original record, on tea from Bengal. The excellent description and figures given by 

 Green render the identification practically certain. 



Tachardia decorella (Maskell). 



On Ficus retusa and iindetermined host, Taihoku, Formosa. 



Mallococcus sinensis (Maskell). 



On undetermined host, Foochow, China. I have at hand part of the type 



material of this species and would redescribe it here (it is hardly or not at all 



recognisable from the original description) were it not that another author has a 

 redescription now in press.

 On Citnis, Ako, Formosa. 



Coccus bicruciatus (Green). 



On Murraya exotica, Taihoku, Formosa. Previously recorded only from Ceylon.
