Porceraspis Ferris, 1938, Microentomology 3 : 75. 

 A lapsus for Proceraspis MacGillivray. 



Porococcus Cockerell, 1898, Ann. and Mag. Nat. Hist. (ser. 7)1: 426. 



type-species : Porococcus tinctorius Cockerell, 1898, by original designation. 



The author suggested a relationship with Solenophora Maskell. Ferris, 1920a : 

 61, considered this a pseudococcine form in the group associated with Pseudo- 

 coccus TVestwood and structurally similar to Erioides Green. 



Porogymnaspis Green, 1916, Bui. Ent. Kes. 7 : 55. 



type-species : Porogymnaspis rufa Green, 1916, by subsequent designation 

 by Ferris, 1936a : 23. 



The author associated this genus with Gymnaspis Xewstead, Parlatoria Targi- 

 oni-Tozzetti, and Leucaspis Targioni-Tozzetti, most nearly related to Leucaspis. 

 Lindinger, 1934 : 26, placed the name as a synonym of Apteronidia Berlese. Fer- 

 ris, 1936a : 23, accepted the genus as valid, and Balachowsky, 1958b : 342, placed 

 it in his Gymnaspidina, grouping with Gymnaspis Newstead, Decoraspis Ferris, 

 Bigymnaspis Balachowsky and Sakaramyaspis Mamet. 



Porphirophora Targioni-Tozzetti, 1867, Soc. Ital. di Sci. Nat. Mem. 

 3 (3): 18. 

 A lapsus for Porphyrophora Brandt. 



Porphyrophora Brandt, 1833, in Brandt and Eatzeburg, Medizinische 

 Zoologie oder getreue Darstellnng und Beschreibimg der Thiere, die

type-species: {Porphyrophora frischii Brandt, lS83)=Coccus polonicus 

 Linnaeus, 1758, apparently by subsequent designation of Kirkaldy, 1906a : 

 254 (the first we have found). 



This genus was established after Margarodes Guilding, 1829, and was used 

 for many years for the reception of the European species of that genus. Later, 

 the name was considered a synonym of Margarodes by Lindinger, 1912b : 307 ; 

 1937: 193, and Morrison, 1928: 220. Silvestri, 1938: 35, on the basis of ex- 

 amination of various species, decided that Porphyrophora should be restored to 

 valid status. Hall, 1940: 494; Borchsenius, 1949: 336; Jakubski, 1950: 398; 

 Dzhafarov, 1956, Akad. Nauk Azerbaid. SSR Izv. 11: SS ; Hadzibejli, 1957: 211, 

 have accepted this view.
