46 Mr. G. R. Crotch's Chronological 



Pallas, in the first fasciculus of the Icones, proposes 

 Mylaris for Tenehrio gigos, L. ; and SiJphoides for Scara- 

 hceus salmlosus [ = Tvo.t', Fab.]. 



Laicharting, in the first volume of the Verzeichniss, 

 re-names three genera, Ostoma \_=^Nit'i(luIa, Fab.], Cly- 

 tra [ = Melolontha, Geoff.] , Adimonia [= (raZerwca, Geoff.] . 

 It is the custom to use this last name for Galei-uca ta- 

 naceti, etc., but that is the type of Geoffrey's genus, of 

 which Adimonia is a mere synonym. 



Acharius, in the Acta Tlolmiensia, founds the genus 

 Bulbocerus \_-=-Letlirus, Scop.]. 



1783. Herbst, in his Verzeichniss, proposes two new 

 genera, but the names of both were pre-occupied, || Der- 

 mestoides \_ = Lyctus, Vah.], and \\ SUphoides \_=^Myctto- 

 phagus, Hellw., Tritoma, Geoff.]. 



Filler, in the Iter per Poseganam, indicates four genera, 

 three of which should be employed : Meloides [=^Cerocoma, 

 Geoff.], Denticollis [=Campylus, Fisch.], Cortice^is, 

 [_=: Hypophloeus, Fahr .] ,Tencbrioidcs [T . mauritanica, Lin., 

 coniplanata, Pill.) . This last is very useful, as Trogosita, 

 Oliv., is always used wrongly, his type being T. ccerulea, 

 and consequently being co-extensive with Temnochila, 

 Westw. 



1784. Laicharting, in his second volume, adds the 

 genus Clytus for Callidium arcuatum, etc. 



Hellenius, in the Acta Eolmiensia, proposes a new genus, 

 Serropalpus {S. striatus) . 



Herbst, in his Mantissa, proposes Lepturoides [ = Denti- 

 collis, Pill., Campylus, Fisch.], and Pterophorus [ = Lym- 

 exylon'\ . 



Hochenwarth, in his Beitrage, indicates by name only 

 the genus Clunipes \_-=Lethrus, Scop.]. 



1787. Fabricius, in the il/aw^/ssa, proposes three new 

 genera, Brentus, Lycus {L. latissima, etc.), and Horia. 

 Olivier, in characterizing Lycits, took Dictyoptera san- 

 guinca for the type, a species not in the Fabrician genus, 

 which should be kept for L. Intissima. He also (and in 

 this he was followed by Fabricius) re-modelled Horia 

 upon TL maculata, a species likewise unknown at the 

 date of the foundation of the genus, which must have for 

 its type H. tcstacea, and thus = Cissites, Latr. 



Thunberg, in the Museum Upsaliense, proposes Hydrous 

 for H. pirevs [ = JTydrophilvs, Geoff.].
