Bulletin of Zoological Nomenclature 48(2) June 1991 107 Case 2292 Histoire ahregee des insectes qui se trouvent aux environs de Paris (Geoff roy, 1762): proposed conservation of some generic names (Crustacea and Insecta) I.M. Kerzhner Zoological Institute, Academy of Sciences, Leningrad 199034 , U.S.S.R. Abstract. Geoffroy's Histoire ahregee des insectes qui se trouvent aux environs de Paris (1762) was rejected for nomenclatural purposes and placed on the Official Index in 1954 (Opinion 228). Many of the 59 new generic names proposed by Geoffroy are in current use and 16 names with authorship from Geoffroy (1762) have already been conserved and placed on the Official List. The purpose of this application is to con-serve the following 24 additional names from Geoffroy (1762): Crustacea: Asellus; Hymenoptera: Diplolepis, Euloplms, Urocerus; Lepidoptera: Pteropliorus; Coleoptera: Altica, Anthrenus, Anthribus, Bostrichus, Cerocoma, Copris, Crioceris, Cryptocephalus, Diaperis, Galeruca, Gyrinus, Hydrophilus, Notoxus, Omalisus, Platycerus, Prionus, Ptilinus, Pvrochroa and Stenocorus. A. Introduction A.l In 1762 Geoffroy published a two volume work entitled Histoire abregee des insectes qui se trouvent aux environs de Paris. In this work Geoffroy proposed 59 new generic names of which four could be regarded as emendations or incorrect spellings of Linnaean names — Dyticus for Dytiscus, Mantes for Mantis, Hepa for Nepa and Tinaea for Tinea. The present-day placement of the 59 new generic names is 1 pseudo-scorpion, 2 Crustacea and the rest Insecta (1 Thysanura, 2 Orthoptera, 1 Plecoptera, 2 Homoptera, 3 Heteroptera, 1 Neuroptera, 6 Diptera, 4 Hymenoptera, 2 Lepidoptera and 34 Coleoptera). In 1954 the International Commission on Zoological Nomencla-ture rejected Geoffroy's work for nomenclatural purposes on the grounds that it was not consistently binominal (Opinion 228). The Commission invited specialists to sub-mit 'applications for the validation [conservation], under the plenary powers, of any names, the rejection of which would, in their opinion, lead to instability or confusion in the nomenclature of the group concerned'. Up to the end of 1990, 18 of the generic names proposed by Geoffroy had been conserved by the Commission and placed on the Official List of Generic Names in Zoology. Sixteen of these 18 names were attributed to Geoffroy (1762); authorship of Crioceris was attributed to Miiller (1764) and of Pteropliorus to Schaeffer ( 1 766). A.2 Two years after publication of Geoffroy's work, O.F. Miiller (1764) pub-lished Fauna Insectorum Fridrichsdalina containing a table comparing the generic In 1978 Dr Kerzhner submitted an application to the Commission in which he considered all Geoffroy's new generic names and proposed the conservation with authorship from Geoffroy (1762) of 29 of them that were then in current usage. Owing to the limited resources of the Commission's Secretariat it has not been feasible until now to complete this very extensive case. Editor.
