Crocidocysta Riibsaamen, 1894. Berlin. Ent. Ztschr. 39 : 218. 



type-species : Crocidocysta froggatti Riibsaaraen, 1894, by nionotypy. 



There seems to be no question that this name is a synonym of Cylindrococcus 

 Maskell, 1892, and that the type-species is identical with C. amplior Maskell, 

 1893. Lindinger, 1910: 156, and 1931a : 114. alleged that C. froggatti Riibsaamen 

 was a psyllid but emended this view, 1937: 182, to indicate that Crocidocysta 

 Riibsaamen partim equaled Cylindrococcus Maskell. 



Crossotosoma Douglas, 1890, Ent. Monthly Mag. 26 : 79. 



type-species : Crossotosoma aegyptiacum Douglas, 1890, by monotypy. 

 This name has long been accepted as a synonym of Icerya Signoret, 1875. 



Cryptaonidia Neave, 1939, Nomen. Zool. 1 : 884. 



A lapsus for Cryptoaonidia Leonardi. 



Cryptaspidiotus Lindinger, 1910, Ztschr. f . Wiss. Insektenbiol. 6 : 156. 



type-species : Clirysomplialus barbusano Lindinger, 1908, by original indica- 

 tion and monotypy. 



The type association of this genus has received some complicated treatment. 

 Although proposed originally for Chrysomphalus barbusano, and for this only, 

 Lindinger, 1931a: 10, in listing the genus said: "Typ : aomdioides n. sp." Later 

 he, 1937 : 182, gave barbusano as the type of the genus. Ferris, 1937c : 51, 53, 

 complicated the matter by listing the type-species as mediterraneus Lindinger, 

 but later in the same year, 1937d : 106, he too specified barbusano. MacGillivray. 

 1921 : 426, included only mediterraneus Lindinger in his treatment of the genus. 

 Balachowsky, 1948b : 269, accepted the genus as zoologically valid and assigned 

 it to his Aonidina. 



Cryptaspidus Lindinger, 1910, Jahrb. der Hamburg. Wiss. Anst, 

 (1909) 2TBeih.3:43. 

 type-species: Cryptaspidus nucum Lindinger, 1910, by monotypy. 



The describer, 1957: 543, offered the opinion that this genus is the "crypto- 

 gynous" form of Pseudoparlatoria Cockerell. 



Cryptes (Crawford MS) Maskell, 1892, New Zeal. Inst. Trans, and 

 Proc. (1891) 24 : 21, nomen nudum ; Cockerell and Parrott, 1899, In- 

 dustrialist 25 : 162. 



type-species : Lecanium baccatum Maskell, 1S92, by subsequent designation 

 by Cockerell and Parrott, and monotypy. 



The authorship and date of publication above are presented in Neave, 1939. 

 Nomen. Zool. I: 8S4. Fernald, 1903b: 209, credited the genus to Crawford, and 

 the type species to Maskell. Assignment of author and publication date has 

 varied in the few recent references that mention the genus. 



Following his description of baccatum, Maskell noted that "Cryptes baccata" 

 was a manuscript name attached by Crawford to the specimens on which 

 Lecanium baccatum Maskell was based. This seems to us to make Cryptes a 

 nomen nudum under the negative restrictions of Article 11(d) of the 1961 Code, 

 as actually, though perhaps not formally, publication in synonymy. We have
