ciety I added one species, Phyllococciis (C'lssococcus?) oahu- 

 etisis, making a total of 16 Dactylopiinae recorded up to that 

 time. 



In the present paper I am adding five genera, of which 

 two are new to science, and nine species, making a total of 

 25 species of Dactylopiinae for these Islands. 



Synopsis of Genera.
