24 PROC. ENT. SOC. WASH., VOL. 21, NO. 2, FEB., 1919 



Type genus. Liparus Olivier, 1807, Entomologie, vol. 5, No. 73, 

 pp. 282-292, not preoccupied by Liparis Artedi, 1736. 



Type germanus Linnaeus, designated by Latreille, 1810, 

 Consid. Gen. 



Molytes Schonherr, 1820, Cure. Disp. Meth., pp. 14, 172, 

 173, has as its originally designated type germanus, Linnaeus, 

 and is hence isogenotypic. 



4. Family Hyperidae Pierce (1916). 



Hyperidae Pierce (1916) mere mention. 



The family corresponds with Lacordaire's Synmerides, phalange 



I, Section B, group I, excepting Scythropides and Promecopides 

 which belong to the Psallidiidae. 



Type genus. Hypera Germar, 1817, Mag. der Ent., vol. 2, pp. 

 339-341. 



Type nigrirostris Fabricius, designated by Leach, 1819, 

 in Samouelle's Entomologist's Useful Compendium, pp. 199- 

 206, and again in 1824, in the second edition of the same. The 

 genus Phytonomus Schonherr, 1826, is considered by most 

 writers as a part of this genus. Our clover and alfalfa weevils 

 should therefore go by the generic name Hypera. 



5. Family Curculionidae Leach (1817) restricted. 



This family has never been properly treated for North America, 

 although such groups as the Anthonomini, parts of Magdalis, 

 Otidocephalus, etc., have been monographed. It corresponds to 

 Lacordaire's Synmerides, phalange II, Section A, group II (Gen. 

 Coleop. VI, p." 538). 



Type genus. Curculio Linnaeus, 1758, Systema Naturae, 10th 

 edit., vol. 1, pp. 377-386. 



Type nucum Linnaeus, designated by Latreille (1810) in 

 Consid. Gen. This genus had become lost by the process of 

 division. Various types have been selected but the first 

 designation is that of Latreille, which is held valid by virtue of 

 Opinion 11 of the International Commission. 



Balaninus Germar (1817) is isogenotypic. The typical 

 Curculionine weevils are therefore those formerly known as 

 Balaninini, the nut weevils. 



6. Family Cionidae, new family. 



This family corresponds with Lacordaire's Synmerides, phalange 



II, Section B, group II (Gen. Coleop. VI, p. 594). 



Type genus. -Clonus Clairville and Schellenberg, 179S, Ent. 

 Helv., vol. 1, p. 64.
