occur in any of his works to which I have access, and is 

 first cited to my knowledge by Latreille (1817). Ble- 

 thisa takes the place of the modern Feloplvila, Blethisa 

 of authors becoming Helobium, Leach, PlatysmazzOmas- 

 eus, Dejean, Dromiiis must be confined to the section 

 Metahletus ; the modern Dromii were referred to De- 

 metrias by Panzer and others, and may be re-named 

 Megalodromius. Lamprias is synonymous with Lebia, 

 Latr, ; if it be desirable to separate L. crux-minor, etc, 

 they may be called CalUlehia. 



Olivier (Enc. Meth. viii.) characterises two genera. 



p. 383. NoTHUS . . Canth. hipundaia, Fabr. 



= Osphya, 111., 1807. 

 617. OziSNA . . 0. dentipes, n. sp. 



Although Olivier first indicates the characters of the 

 genus Nothus, yet I think that Illiger's name is to be 

 preferred, as he clearly indicated the typical species. 



Latreille (Enc. Meth. viii.) characterises one new 

 genus. 

 p. 677. Pamborus . P. alternans, n. sp. 



Paykull (Mon. Hister.) separates — 

 p. 103. Hololepta . Hister planus. 



1812. 



Ahrens (Nov. Act. Halens. ii.) forms — 



EucNEMis . Elater capucinus. 



Germar {op. cit.) proposes — 



PoTAMOPHiLus Pamus acuminatus. 



Fischer de Waldheim (Mem. Soc. Nat. Mosc. iii.) 

 figures an entirely new genus, 

 p. 281. Pogonocerus . P. thoracicus, n. sp. 



1813. 



Bonelli (Mem. Acad. Turin, xx.) in the second part 

 of his paper adds five new genera. 



p. 466. Dic^Lus. 



453. Hellug . . H. costatus, n. sp.
