60 THE ENTOMOLOGIST. 



Mr. Kirby and others, it was found desirable some time ago to 

 appoint a special Nomenclature Kevision Committee, consisting 

 of Messrs. Nicholson, Bobbins, Woodward, and Prout, to investi- 

 gate these changes, and recommend the adoption of such as they 

 found to be incontrovertibly correct. The first revision of the 

 Macro-Lepidoptera has now been completed, and adopted by the 

 Council ; no claim is made of finality, and indeed many of 

 Kirby's generic changes — such as the resuscitation of names 

 from Hiibner's ' Verzeichniss,' which contains so many " mixed 

 genera " — have been left untouched until more biological work 

 has been done at the question of natural genera ; and some 

 necessary changes also have been deferred until some recognised 

 British authority has brought them before the notice of the 

 entomological public in this country. 



The following is the list of alterations from South's ' List ' 

 (which is still to form the basis of the Society's nomenclature) 

 thus far adopted. The references give a brief indication of the 

 literature consulted in sifting the questions raised, but is of 

 course very far from exhaustive, one or two references to 

 accessible works being made to suffice ; whereas in the work of 

 the Committee it was frequently necessary to verify quotations 

 by consulting the original descriptions, &c. : — 



1. The generic grouping and nomenclature of the Ehopalocera 

 to follow Tutt's ' British Butterflies,' with the few exceptions noted 

 below. 



2. Adopcea, Billb. (1820), to replace Thymelicus, Hb. (Kirby, 

 Handb. Lep. iii. 19). 



3. Plebeius argus, Linn., for cegon, Schiff. ; P. argyrognomon, 

 Bgstr., for argus, Auct., not yet recorded as British (Kirby, 

 Handb. Lep. ii. 88, 89). 



4. P. alexis, Scop. (1763), for astrarche, Bgstr. (I. c, p. 99). 



5. Pontia, Fb. (1807), daplidice, for Pieris daplidice (I. c, 

 p. 151). 



6. Leptidia, Billb. (1820), for Leucophasia, Steph. {I.e., p. 178). 



7. Erippus, Cram., var. menippe, Hb. = archippus, Fb., nee 

 Cram. = plexippus, Scud., nee Linn., for archippus, Fb. (Kirby, 

 Entom. xxix. 189). 



8. Satyridi and Satyrus, Latr., for Hipparehiidi and Hip- 

 parchia, Fb. ; Hipparchia, Fb., for Enodia, Hb. (Kirby, Handb. 

 Lep. i. 131 ; South, Entom. xxx. 275 ; Moore, Entom. xxx. 326). 



9. Lineata, Fb., to be deleted as synonym for Deilephila 

 livornica (Kirby, Hand. Lep. iv. 28, 30). 



10. Amorpha, ~H.h.,populi, L., for Smerinthus popidi (Z.c.,p. 58). 



11. Dilina, Dalm., tilice, L., for S. tilice (I.e., p. 56). 



12. Hemaris, Dalm. (1816), for the separation of the bee- 

 hawks from Macroglossa stellatarum (Kirby, Handb. Lep. iv. 4). 



13. Fuciformis, Linn., and tityus, Linn., for the species of 

 Hemaris, as indicated in Entom. xxix. 39.
