and the difference in nomenclature. The generic nomenclature 

 has received very careful attention by the writer and is in strict 

 adherence to the rules of nomenclature and the opinions of the 

 International Commission on Zoological Nomenclature. In the 

 following discussion the type genera are considered only. 



i. Family Psallidiidae Pierce (1916). 



Otiorhynchidae LeConte (1S74). 



Brachyrrhinidae Bedel (1885). 



Brachyrhinidae Pierce (1913). 



Psallidiidae Pierce (1916). 



The North American classification is treated by the writer 



in Proc. U. S. Nat. Mus., vol. 45, pp. 372-426, May 23, 11)13. 



Type genus. Psallidium (Hellwig) Illiger, 1798, Verzeichniss 

 der Kafer Preussens, p. 497. 



Type maxillosus Fabricius, designated by Schonherr (1826) 

 in Cure. Disp. Meth., and (1833) in Gen. et Sp. Cure. The 

 genus has generally been dated from Illiger (1807) in which 

 it is also spelled Psallidium, or from Schonherr (1826) where 

 it is spelled Psalidinm. It is the oldest genus in the family, 

 antedating Brachyrhinus Latreille (1802). 



2. Family Psaliduridae Pierce (1916). 



Amycteridae MacLeay (1866). 



Psaliduridae Pierce (1916) mere mention. 



The family corresponds with Lacordaire's Synmerides, phalange 

 I, Section A, group I (Gen. Coleop. VI, p. 290). 

 Type genus. Psalidura Fischer, 1823, Mem. Soc. Imp. Nat. 



Mosc., vol. 6, p. 265. 



Type mirabilis Kirby, monotypic. 



Amycterus (Dalman) Schonherr, 1826, Cure. Disp. Meth., 



p. 202, has as its type, mirabilis Kirby, by original designation, 



and is hence as isogenotypic synonym of Psalidura. It is 



therefore necessary to rename the genus known as Amycterus 



in our literature. 



Pseudamycterus, new genus. 



Amycterus auct., and Gemminger and Harold, 1871, Cat. Coleop., 

 p. 2342 (not Amycterus Schonherr, 1826). 

 Type. Amycterus schonherri Hope. 



3. Family Liparidae, new family. 



Plinthidae Pierce (1916) mere mention. 



The family corresponds with Lacordaire's Synmerides, phalange 

 I., Section A, group II (Gen. Coleop. VI, p. 2!)0).
