Ferrisia Fullaway. 1923. Hawaii. Ent. Soc. Proc. 5 : 309, 311. 



type-species : Dactijlopius virgatus Cockerell, 1S93, by original designation 

 and rnonotypy. 



This is currently accepted as a valid zoological unit in the Pseudococcidae. 



Ferrisiana Takahaslii, 1929, Formosa Nat. Hist. Soc. Trans. 19 : 429. 



Takahashi proposed this name to replace Ferrisia Fullaway on the grounds 

 that the latter was preoccupied by Ferrissia Walker, 1903 (Mollusca). This 

 usage had some currency for a time., but the change was unjustified, in our 

 opinion, on the basis of earlier Code rules, and the 1961 Code in Article 56(a) 

 forbids a change of generic name if there is so much as one letter difference, 

 which applied in this instance.

Ferrisicoccus Ezzat and McConnell, 1956. Md. Agr. Expt. Sta. Bull. 

 A-84: 13.31. 



type-species : Ferrisicoccus angustus Ezzat and McConnell, 1956, by original 

 designation. 



The describers assigned this genus to the Planococcini, Pseudococcidae. 



Ferrisidiaspis Bodenheimer, 1951, Ent. Ber. 13 : 329. 



type-species : Diaspis syriaca Lindinger, 1912, by original designation and 

 rnonotypy. 



Balachowsky, 1954e : 173, placed this name as a synonym of Diaspis Costa. 



Filippia Targioni-Tozzetti. 1868, (separate) Soe. Ital. di Sci. Xat. 

 Atti 11: 33; 1869, 11: 726. 



type-species : Philippia foUicularis Targioni-Tozzetti. 1S6T, [Coccus oUae 

 A. Costa, 1S57, partini (non O. G. Costa, 1828)], by substitution of Filippia 

 for Philippia and present designation. 



Targioni-Tozzetti first presented this zoological unit in 1867 as Philippia. He 

 change the spelling to Filippia in 1868: 33, without any explanation and in so 

 doing escaped the priority problem set up by Philippia Gray, 1S47 (Mollusca). 

 It has been customary among coccid cataloguers and other workers to credit the 

 type-species of this genus to 0. G. Costa, 1S2S. However. Targioni-Tozzetti was 

 specific in designating certain figures in a plate published in 1S57 by A. Costa as 

 the basis for his genus, and for Targioni-Tozzetti's foUicularis. We have studied 

 the descriptive material presented by O. G. Costa, 1S2S. and conclude that it 

 contains only a presentation of the coccid species currently called Saissetia 

 oleae (Bernard) and that there is no certain evidence that it contains any ma- 

 terial that suggests the type-species of Filippia. We have also reviewed mate- 

 rial presented by A. Costa, 1S57, under the designation Coccus oleae, and consider 

 that it, too, relates primarily to the Sais»ttia oleae of current understanding. 

 We therefore conclude that it is best to designate the type-species of Filippia as 

 F. foUicularis (Targioni-Tozzetti). 1S67. A. Costa, 1877, in the revised edition
