ciety I added one species, Phyllococcus (Cissococcus?) oahu- 

 ensis, making a total of 16 Dadyhpiinae recorded up to that 

 time. 



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

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

 25 species of Dactjlopiinae for these Islands.
