Study of Genera of Coleopiera. 43 



1740. In the second edition the order of the genera 

 is entirely altered ; Lucanus and Buceros are merged in 

 Scarahceus ; in the Hentiptera, Staphylinus is used for the 

 modern Blatta, despite the fact that Ray^s Stapliylinus 

 was our Ocypus olens. 



1747. In the sixth edition, Gyrinus and Lampyris are 

 further suppressed, Elater supplants Notopeda, and Tene- 

 brio is proposed for the original Blatta (the modern Blaps) , 

 a signification it long retained. Necydalis is now used 

 for N. minor; Buprestis is transferred to the modern 

 genus, plus Spondylis huprestoides ; Staphylinus is used 

 in the original sense of Ray. 



1758. In the tenth edition only two genera are added, 

 Ulster and 8ilpha. 



1762. Geoffrey, in his Histoire ahregee, divides the 

 Coleoptera into fifty genera, displaying a degree of acu- 

 men far in advance of his age, which was but little 

 appreciated by his contemporaries; the ill-concealed 

 jealousy of Linnasus is only too evident in his twelfth 

 edition. Olivier and Latreille succeeded in restoring 

 the majority of Geoffrey's names, but there are still 

 several which must be adopted. The new genera are — 



Platycerus {Lucanus cervus) , Ftilinus , Copris, Attelahus 

 {•=Hister, L.), Byrrhus (Anohium domesticum) , Anthre- 

 nus, Cistela {Byrrhus pilula), Peltis { = Silpha), Cucujvs 

 {=iBuprestis, L.), || Buprestis {=-Carahus, L.), Bruclius 

 {Ptinus fur) , \\ Gicindela {Telepliorus fuscus) , Omalisus, 

 Hydrophilus {H. piceus) , Melolontha {Glytra 4i-puncta- 

 ta), Prionus, StenoGorus {Leptura meridiana) , Luperus 

 [Lyperus'j, Gryptocephalus, Grioceris {G. 12-punctata) , 

 Altica {Podacjrica fuscipes) , Galeruca {G. tanaceti), My- 

 labris {Bruchus pisi) , Rhinomacer, Bostrichus {B. capu- 

 cinus) , Glerus {G . apiarius) , Anthribus {Brack, scabrosus) , 

 Scolytus, Anaspis, Tritoma {Mycetophagus 4i-pustulatus) , 

 Diaperis, Pyrochroa, Notoxus, Gerocoma. 



He also defines certain Linnaean genera as follows : — 

 Tenebrio {Asida rugosa), Gurculio'^ {Gleonus nebulosus), 

 Staphylinus {Ocypus olens), Gerambyx {G. alpinus) , Peltis 

 {Silpha 4-punctata) , Gucujus {Buprestis rustica) , Elater 

 {Ludius ferrugineus) , Buprestis {Garabus auratus) , Ghry- 



* This was kept for Cleonus by Fabricius and Germar, and ought to be 

 retained.
