Study of Genera of Coleoptera. 45 



here from Olivier and Latreille. For example, he takes 

 up the name ByrrUus from Geoffrey, and applies it 

 to Cistela, Geoff., the Byrrhus of Linnaeus being an 

 Anthrentis. One could imagine he had never seen 

 Geoffrey's work, since he cites his description and figure 

 of Mycetophagus Ai-pustulatus as a synonym to Tri^oma 

 hipustulata, F., and his description of Byrrhus inlula to 

 Dascylus cervinus. In all, he adds 39 genera — 



Trox, \\ Melolontha [nee Geoff.], Trichius, Oetonia, 

 Apate {A. muricata) , Melyris, Anohium [= Byrrhus, 

 Geoff., P^mws, Linn.], \\ B%jrrh.us [nee Geo^.; = Cistela, 

 Geoff.], fPtinus [necLmn., = Bruchus,GeoS.'\ , Elophorus, 

 Sphceridium, f Tritoma [_nec Geoff.] , Nicrophorus, Opa- 

 trum, Nitidula, Alurnus, \\ Cistela [nee Geoff.], Erotylus 

 {E.fasciatus,F., 1801), Lagria, Zygia, Zonitis, Apalus, 



II Spondylis, Lamia {L. textor, Oliv.), Calopus, Rhagmm, 

 Saperda {S. populnea, 0\iv.) , GaUidium {C. sanguineum, 

 Oliv.), Donacia, Lyniexylon, \\ Gucujus [nee Geoff.], 

 Malachius, f Necydalis [iiec Linn., =(Edemera, Oliv.], 

 Elaphrus, Scarites, 8epidium, Pimelia, Scaurus, Blaps, 

 Helops, Erodius, Lytta [=Cantharis, Linn.], || Mylabris 



[riec Geoff.], Oxyporus, Pa^derus. 



1777, Schgeffer, in his Appendix, adds four genera, 



Buprestoides [ = 31elasis, Oliv.], Cleroid.es {Clerus formi- 

 carius) , Dermestoides {Orthopleura sanguinicollis) , Elater- 

 oides l = Hylocoetns] . Of these, the first is inadmissible ; 

 the others should be retained. 



Fabricius, in his Genera Insectorum, adds no new genera, 

 but adopting the name f Ips from De Geer, proceeds to 

 apply it to a curious mixture of Nitidula, Engis, etc. The 

 generic character given is still more embarrassing, as he 

 says that they live in carcases. 



Scopoli, in his Introd^cctio, adds the genus Lethrus for 

 Scarahceus cephalotes, and in the Appendix he also adds 

 Gibhium for a new species of Ptinus, Fab. 



1778. Czempinski, in his Dissertatio inauguralis, also 

 forms the last mentioned genus, under the name Scotias. 



De Geer, in the seventh volume of his Memoires , iorms 

 the genus Antipus, now regarded as a Glytra. 



1781. Fabricius, in the Species Insectorum, adds the 

 genus Manticora.
