I02 FAUNA HAWAIIENSIS 



§ 2. Systematic account of the Hemiptera. 



Suborder Homoptera. 

 Tribe MONOMERA. 



Fam. COCCIDAE. 



This family has been dealt with in a preliminary manner by Maskell and Cockerell. 

 Koebele' mentions " sixty species or thereabout," but does not catalogue them. 

 Maskell and Cockerell enumerate 47 species, included in 15 genera of which Aspidiotus, 

 Coccus and Pseudococciis are richest ; but the validity for specific rank of some of the 

 forms appears to be considered doubtful. I cannot accept responsibility for the 

 nomenclature here adopted, as no work with which I am acquainted gives full and 

 correct references to all the genera which usually are mentioned merely by name, even 

 in the works of Signoret, Cockerell, Maskell, and Green. 



There are possibly no precinctive species, though I cannot find that three forms 

 have been noted from outside the Hawaiian area ; these three are Howardia prnnicola, 

 Aspidiohis perseai'um and A. cydoniae var. tecta.
