AN ANNOTATED LIST OF GENERIC NAMES OF THE COCCOIDEA 71 



Article 11(d) of the 1961 Code, as actually, though perhaps not formally, publica- 

 tion in synonymy. The first affirmative action in giving generic type status to 

 Erium was that taken by Cockerell, as cited, where he definitely considered it to 

 be a subgenus of Dactylopius [i.e. Pseudococcus of current usage] and cited 

 Dactylopius glooosus Maskell [1892] as the type-species. We therefore believe 

 that the genus should stand as Erium Cockerell, 1897, with type-species Dacty- 

 lopius glooosus Maskell, 1892, by subsequent designation and inonotypy. 



Morrison and Morrison, 1922 : 48, redeseribed the type-species, globosum, and 

 noted the serious misunderstanding of the genus that had resulted from the 

 Maskell distribution to coccid workers of specimens from other than the type lot. 

 The genus as redefined from the type specimens was shown to be a characteristic 

 pseudococcine form, differing from the genus Trionymus Berg, as then consti- 

 tuted, primarily in the possession of a rotund rather than an elongate, parallel- 

 sided body. A tentative synonymical association was suggested in this discussion 

 but was not made positive. Lindinger, 1935a : 121, definitely recorded the synon- 

 ymy of Trionymus with Erium and transferred a considerable number of species 

 names to Erium. In his 1937 list of coccid genera, he placed 9 additional names 

 as synonyms of Erium, an action resulting largely from his acceptance of Triony- 

 mus and its numerous synonyms as identical with Erium. One name so placed by 

 him, Amonostherium Morrison (p. 179), is clearly an error, as its type was 

 definitely stated to be a common North American species having little or no 

 morphological relationship with true Dactylopius glooosus Maskell. The classi- 

 ficatory status of this genus remains in question. It seems to have been pretty 

 much overlooked by more recent students of the Pseudoeoccidae and its type- 

 species, glooosum, is much in need of restudy to establish Erium in a proper 

 relation to the flood of new pseudococcid genera that have been proposed in recent 

 years, 



Essigaspis MacGillivray, 1921, The Coecidae, p. 306. 



type-species : Protodiaspis agrifoliae Essig, 1914, by original designation 

 and monotypy. 



Ferris, 1936a : 21, 24, 26, and 1937 : SI-99, placed this name as a synonym 

 of Protodiaspis Cockerell. 



Eucalymmatus Lindinger, 1943, Arb. iiber Morph. u. Taxonom. Ent. 

 10:147. 



An emendation of Eucalymnatus Cockerell. 



Eucalymnatus Cockerell, 1901, in Cockerell and Parrott, Canad. Ent. 

 33 : 57. 



type-species : Lecanium tessellatum Signoret, 1873, by original designation 

 and monotypy. 



Its proposer presented this as a subgenus of Lecanium Burmeister, but it 

 stands as a genus in the Fernald Catalogue, 1903b : 165, and has been used 

 constantly by coccid students since its proposal. 



Eudinaspis Lizer, 1942, La Plata Univ. Nac. Inst. Mus. Notas 7 (Zool. 



56) : 76-78. 



type-species : Eudinaspis jorgenseni Lizer, 1942, by monotypy. 



Its proposer placed this genus in the Diaspidini with a suggested close rela- 

 tionship to Dinaspis Leonardi.
