Physokermes Targioni-Tozzetti, 1868, (separate) Soc. Ital. di Sci. 

 Nat. Atti 11 : 41 ; 1869, 11 : 734; Signoret, 1874, Soc. Ent. de France 

 Ann. (ser. 5) 4: 87. 



type-species : Coccus liemicryplius Dalman, 1825, by subsequent restriction 

 of the genus to this single species by Signoret, 1874 : 87. 



The author presented this genus without descriptive notes but with four associ- 

 ated species in the Lecanites. Signoret, 1874: 87, restricted the genus to liemi- 

 cryplius Dalman and described both genus and species. Lindinger, 1933a : 117, 

 considering quercus Linnaeus the type-species because it was first-named, placed 

 Physokermes in synonymy with Kermes [Talla Heyden of Lindinger] because of 

 identity of type-species. This action has not been accepted by other workers. 

 Schmutterer, 1956 : 454, reviewed the situation and confirmed liemicryplius 

 Dalman, long considered a synonym of piceae Schrank, 1801, as the type-species 

 and as distinct from piceae. Borchsenius, 1957: 439, accepted Physokermes as 

 valid but cited piceae Schrank as type-species and placed hemiwyphus Dalman 

 as a synonym of it. 



Piannaspis Dunham, 1954 [Bahia], Bol. Inst. Biol. 1: 72. 

 A lapsus for Pinnaspis Cockereil. 



Pilococcus Takahashi, 1928, Formosa Nat. Hist, Soc. Trans. 18 (97) : 

 257. 



type-species : Pilococcus miscanthi Takahashi, 1928, by original designation 

 and monotypy. 



The author placed this genus close to Ripersia Signoret in the Pseudococcidae. 



Pinnapsis Lindinger, 1954, Beitr. z. Ent, 4 : 620. 

 A lapsus for Pinnaspis Cockereil. 



Pinnaspis Cockereil, 1892, Inst. Jamaica Jour. 1 : 136. 



type-species: (Mytilaspis pandani Comstock, 1881) =Aspidiotus ouxi 

 Bouche, 1851, by subsequent designation of Fernald, 1903b : 242. 



The author proposed this as a subgenus of Mytilaspis Targioni-Tozzetti with 

 two definitely included species, pandani Comstock and ouxi Signoret. Its valid- 

 ity has never been challenged but there has been some uncertainty as to the 

 relation of certain genera to it. Lindinger. 1912b : 58, 79. first indicated the syn- 

 onymy of Hemichionaspis Cockereil with Pinnaspis. Jaapia Lindinger and Lepid- 

 aspidis MacGillivray are also considered to be synonyms. See Ferris and Rao, 

 1947, for details. 



Pityococcus McKenzie, 1942, Microentomology 7: 3-4. 



type-species : Pityococcus ferrisi McKenzie, 1942, by original designation. 



The author established the Pityococcini in the Coelostomidiinae for this mar- 

 garodid genus. 



Planchonia Signoret, 1870, Soc. Ent. de France Ann. (ser. 4) 10 : 282. 



type-species : Coccus fimbriatus Fonscolombe, 1834, by monotypy. 



Signoret established this genus because he considered that fimbriatus Fons- 

 colombe should be removed from Eriococcus, in which Targioni-Tozzetti had
