The name Piercolias was introduced by Grote as a replacement for Trifurcula Staudinger, 

 1894, which is invalid under the Law of Homonymy.

 Mag. 4 : 195) : Papilio nereis Drury, [1782], III. nat. Hist. 3 : index et 48, pi. 35, figs. 2, 3. 

 The name Pierella is always attributed to Westwood [1851], but as so published, it is 

 invalid, as it was then published in a synonymy (Article 11(d)). This name was introduced 

 by Westwood in the course of his very complicated treatment of the genus Haetera Fabricius, 

 1807. That genus was divided by Westwood into two main divisions, each of which was 

 divided into sections, these latter being subdivided into subdivisions. The point to be noted 

 is that Westwood did not himself assign names to these divisions but sometimes in connection 

 with them cited one or more generic names, these being sometimes already published generic 

 names, in other cases manuscript names. In accordance with this procedure Westwood 

 cited in connection with his second main division three generic names, of which two were 

 already published names and the third the manuscript name Pierella. It is clear from 

 Westwood's treatment that he did not look upon himself as introducing Pierella, it being 

 evident that he looked upon that name as being no more than a manuscript synonym of 

 Haetera Fabricius. 



The first author to use Pierella as the name for a taxonomically valid genus was Herrich- 

 Schaeffer who included in this genus all the species cited by Westwood as belonging to the 

 second of his main divisions of the genus Haetera Fabricius, together with others. The species 

 selected as the type-species {Papilio nereis Drury) by Butler belonged to the group established 

 by Westwood and was included in that recognized by Herrich-Schaeffer. That selection 

 would have been valid for Pierella Westwood if that had been a properly published name and 

 is valid for the properly published name Pierella Herrich-Schaeffer. Scudder (1875, Proc. 

 amer. Acad. Arts Sci., Boston 10 : 250) was the first author to specify the above species as the 

 type-species of Pierella both as of Westwood and as of Herrich-Schaeffer.

This generic name has been placed by the Commission — in its Opinion 278 — on the Official 

 List of Generic Names in Zoology as Name No. 704. 



PIERIS Hubner, [1819], Verz. bekannt. Schmett. (4) : 53. Type-species by selection by

(4) : 53- 



Hubner took as the holotype of his new nominal species Pieris dracontis the specimen 

 which in 1780 Cramer had misidentified as Papilio lena Linnaeus, 1767 (Syst. Nat. (ed. 12) 

 1 (2) : 784) and had figured under that name (Uitl. Kapellen 4 (25) : 5, pi. 291, figs A, B).
