AN ANNOTATED LIST OF GENERIC NAMES OF THE COCCOIDEA 55 



coccus Costa . . . which is the first mentioned is to be regarded as type of the 

 genus. D. coccus is said to be Coccus cacti L., but instead of being a synonym of 

 that species {Monoplileous cacti [see 1899j : 261]), it is the first available name 

 for the commercial cochenille." This statement ignored the previous potential 

 type fixation through the substitution of Dactylopius for Diaprosteci and the 

 actual previous type fixation by Targioni-Tozzetti, but it was accepted by Fernald 

 1903b, and seems to have had substantial usage subsequently by critical students 

 of coccid taxonomy, with the exception of Green, 1912a, and MacGillivray, 1921. 

 Lindinger, 1937 : 182, accepted Dactylopius as valid for his list of coccid genera. 

 Laing, 1944 : 93, discussed the name in connection with his comment on the genus 

 Pseudococcus Westwood, as did Ferris, 1950b : 170, and 1955a : 85. Kirkaldy, 

 1904a : 254, and 1906a : 254, presented various observations on the status and type 

 of this genus but his opinions do not seem to be significant or, indeed, germaine 

 to the alignment of the genus. 



It is our opinion that the zoological concept of this genus as standing for the 

 Mexican cochineal and its relatives is now sufficiently established in taxonomic 

 literature to make its continued use as the accepted designation for these coccids 

 highly desirable. But a decision in its favor under the Plenary Powers of the 

 International Commission is clearly required to make its use valid. 



Dactylopus Signoret, 1875, Petites Nouvelles Ent. 7 : 499. 



This name was printed in Signoret's description of Dactylopus oromeliae n. sp. 

 We consider it to be a lapsus for Dactylopius O. G. Costa, which was then in use 

 for the mealybug genus now called Pseudococcus Westwood. 



Daraspis Hall, 1946, Roy. Ent, Soc, London, Trans. 97: 511. 



type-species : Chionaspis oussii Newstead, 1911, by original designation and 

 monotypy. 



The proposer of this genus suggested a relationship to Sinistraspis MacGil- 

 livray. Balachowsky, 1954e : 23, 172, suggested two different assignments for it, 

 the first in Lepidosaphedina, the second in Diaspidina, group II, chionaspiform. 



Dattilopii O. G. Costa, 1835, Fauna del Regno di Napoli, Famiglia de' 

 Coccinigliferi, o de' Gallinsetti. Emitter! Napoli, p. 2. 



Costa presented this italicized and capitalized name as one of the "three dis- 

 tinct genera" into which he divided the coccid group. It has never attained 

 standing in coccid literature and may actually be a vernacular name. 



Decoraspis Ferris, 1955, Microentomology 20 : 31-32. 



type-species : Aonidia cornigera Green, 1896, by original designation. 



This name was proposed by Ferris as a replacement for Greeniella "Mac- 

 Gillivray 1921 : 395." In our opinion this was an unnecessary proposal since 

 MacGillivray, 1921: 395, actually stated "Greeniella Ckll." [1897]. Thus 

 Decoraspis is a synonym of the Cockerell name. See Greeniella MacGillivray. 



Delococcus Ferris, 1955, Microentomology 20 : 5. 



type-species : Formicoccus tafoensis Strickland, 1947, by original desig- 

 nation. 



This was placed in the Pseudococcidae.
