50 Mr. G. R. Crotch's Chronological 



1797. Andersch, in Hoppe's Taschenhuch, proposes 

 the name Bohticola for Sil})ha grossa, etc., which must 

 be accepted. 



Herbst, in his seventh volume, adds Apian, Fsoa, Kolon, 

 and Boros. 



Thunberg, in the Acta Hohniensia, characterizes Cordyle 

 [ = RUyncliophorus, Herbst] . 



1798. Clairville, in the Entomologie Helvetique, pro- 

 ceeds to subdivide Curculio into several genera, viz., 

 Cossonus, Calandra {G. granaria) , Cionns {C. hlattarice) , 

 Rhynchcenus [R. xylostei) , Ramplius, Flatyrltinus, Myc- 

 tcrus. Of these, all are retained except RliyncJtcenus, 

 which, however, must be, if priority is to be observed. 

 Rhinomacer he defines from Apioii frurncutarium, and 

 Anthribus from Salpmgiis riiJicolUs. 



Fabricius, in his Supplementum, adds four genera, f Geo- 

 trupes \_nec Latreille] , Onitis {0. clinias, iS)tnrm.), Lema 

 (L. merdigera, ¥., 1801), and Dirccea. {L. harhatum, ¥., 

 1801) . He also gives as his own, Endoiuychus (Hellwig) 

 and Glytra (Laicharting) . Lema is co-extensive with 

 Grioceris, Geoff., and Dirccea identical with Serropalpus, 

 Hellenius. 



Uliger, in the Verzeichniss der Kafer Freussens, gives 

 really tangible generic characters. The new genera are 

 Oryctes [= Biiceros, L.], Aphodius {A. fossor) , Anisotoma 

 {A. glabra and hunieralis) , Agathidiuvi (= Volvoxis, Kug.), 

 Sarrotriimi [ = Orthocerus, ha.tr. 1 , and Spercheus (Kugel.). 

 Anisotoma and Leiodes are intcrchauged by Erichson, 

 and should be reversed. He proposed to use Feltis for 

 Silpha grossa; Latreille (1803) objecting to this, pro- 

 posed Tkymalus. Kugelann appears to have had clearer 

 ideas about the Melandryadce than most people of his 

 time, and proposed Brontes for Serropalpus Icevigatus 

 [ = Dirccea, Muls., Hypulns, Payk.] and Mystaxis for S. 

 dubius and bifasciaius l = IIypalus, Muls.]. 



Paykull, in the first volume of his Fauna, forms five 

 new genera, the types being carefully indicated : Oda- 

 ca^itha,, Xylita {X, buprestoidcs, Fab.), Jlypnlns [H. 

 4-guttatus) , Antlvicns [A. monoccros) , Gatops ((7. scricea). 

 Hypulus is evidently Dirccea, Muls. {')tec Fabr.) and 

 Brontes, Kugel., hence Hypulus, Muls., might take
