PREFACE 
This publication contains additions and corrections to “An Anno- 
tated List of Generic Names of the Scale Insects (Homoptera: Coc- 
coidea” by Harold Morrison and Emily R. Morrison, published in 
October 1966. It extends through December 31, 1963, as did the Mor- 
rison and Morrison publication, and in addition includes citations to 
a 1965 paper by De Lotto, which has a crucial bearing on certain 
coccid generic names, and the 1966 diaspidid catalog of Borchsenius. 
Morrison and Morrison treated names proposed by Amyot, 1847: 
488-503, as uninominals and hence as invalid names without explain- 
ing their action. Neave listed the Amyot names without comment. 
Although inclusion in Neave’s list does not imply validity of the names, 
their presence there has led some workers to question the correctness of 
the Morrison and Morrison conclusions. 
It therefore seems relevant to note the following statement by 
Amyot, 1845: 369: “Ce qui doit le plus frapper au premier abord, dans 
cet ouvrage, est le mode de nomenclature que nous y avons adopté, 
sous le titre de Méthode mononymique, et qui consiste dans l’applica- 
tion d’un nom unique, donné a chaque espéce, au lieu de deux, le nom 
générique et le nom spécifique, comme cela se pratique dans la nomen- 
clature en usage depuis Linné.” 
This system obviously does not meet the requirements of Article 
11(c) of the International Code of Zoological Nomenclature. The 
matter was settled unequivocally by the International Commission in 
Opinion 686, 1963: 423, when Amyot’s Méthode mononymique was 
placed on the Official Index of Rejected and Invalid Works in Zoologi- 
cal Nomenclature. 
Tt is evident from their comments on Amyot names that Morrison 
and Morrison were not aware of Opinion 686. 
A few Amyot coccid names were omitted by Morrison and Morrison. 
They are included in the present list for the sake of completeness, and 
notes or corrections are added under a few Amyot names included 
by Morrison and Morrison. 
Morrison and Morrison usually cited the name of a type-species 
in its original combination but sometimes cited a later combination if 
one had been used by the describer of the genus. In the latter instances 
that I have recognized, I have added or substituted the original name 
combination of the type-species.
