Bulletin of Zoological Nomenclature 329 OPINION 835 MELANOPLUS STAL, 1873, ACRYD/UM FEMURRUBRUM DE GEER, 1773, AND GRYLLUS SANGUINIPES FABRICIUS, 1798 (INSECTA, ORTHOPTERA): ADDED TO THE OFFICIAL LISTS RULING. — (1) The generic name Melanoplus Stal, 1873 (gender: mascu- line), type-species by designation by Scudder, 1897, Acrydium femurrubrum de Geer, 1 773, is hereby placed on the Official List of Generic Names in Zoology with the Name Number 1775. (2) The following specific names are hereby placed on the Official List of Specific Names in Zoology with the Name Numbers specified : {a) femurrubrum de Geer, 1773, as published in the binomen Acrydium femurrubrum (type-species of Melanoplus Stal, 1873) (Name No. 2220); (b) sanguinipes Fabricius, 1798, as published in the binomen Gryllus san- guinipes (Name No. 2221). HISTORY OF THE CASE (Z.N.(S.) 1695) The present case was submitted to the office of the Commission by Drs. D. K. McE. Kevan and V. R. Vickery in February 1965. The application was sent to the printer on 22 February 1965 and was published on 18 May 1965 in Bull. zool. Nomencl. 22 : 105-107. The proposals were supported by Dr. K. H. L. Key and Dr. R. L. Edwards (Bull. zool. Nomencl. 23 : 76). In his comment Dr. Key drew attention to a misunderstanding by the authors con- cerning the application of Article 23b of the Code. DECISION OF THE COMMISSION On 20 July 1967 the Members of the Commission were invited to vote under the Three-Month Rule on Voting Paper (67)28 either for or against the proposal set out in Bull. zool. Nomencl. 22 : 106. At the close of the prescribed voting period on 20 October 1967 the state of the voting was as follows: Affirmative votes — twenty-one (21), received in the following order: China, Holthuis, Yokes, Sabrosky, Lemche, Evans, Obruchev, Boschma, Mayr, Brinck, Simpson, Munroe, Tortonese, do Amarai, Uchida, Jaczewski, Mertens, Kraus, Alvarado, Ride, Forest. Negative votes — one (1): Binder. Yoting Papers not returned — one (1): Hubbs. Professor Bonnet returned a late affirmative vote. The following comments were made by Commissioners in returning their votes : Bull. zool. Nomencl., Vol. 24, Part 6. January 1968. 330 Bulletin of Zoological Nomenclature Prof. E. Mayr (18.viii.67): " It seems to me that Art. 23b does not strictly apply to this case since the junior synonym (bililuratus) was used for the migra- tory grasshopper only for the four years 1958-1961, and not for a fifty-year period." Prof. P. Brinck (18.viii.67): "This is a very attractive solution of the problem." Dr. W. D. L. Ride (19.x. 67): "The Commission is being asked to apply Art. 23b, but its hand has been forced by those who have chosen to disregard Art. 23b (ii). This case serves to emphasize the importance of urgent action (both by ' discoverers ' and by the Commission) in respect of cases involving this Article. Names in suspension under Article 23b (ii) can only result in a state of instability in nomenclature until their future is decided. Moreover, any published use of any name for such a taxon during the period of suspension of its oldest name must influence the subsequent decision by the Commission which must take into account universality and usage."
