Tlio superfamily Doydirhynchoidea is the old family Khinoma- 

 ccridae. The genus name Rhinomacer was first used by Geoffroy in 

 1762 for 11 species, only one of which was definitely associated by 

 quotations with a named species. This was Attelabus coryli Limiaeus, 

 which has been designated by Bedel (1885) as type of Attelabus 

 Linnaeus (1758). The Fabrician (1787) genus Rhinomacer is based on 

 attelahoides Fabricius and is a synonym of Cimheris Des Gozis. The 

 oldest generic name available is therefore Doydirhynchus Dejean 

 (1821) based on austriacus OHvier. This generic name has been fre- 

 quently emended. 



The superfamily Attelaboidea has as its type-genus Attelabus Lin- 

 naeus (1758) and contains the following famihes: Apionidae (Behdae), 

 Attelabidae, Tachygonidae, Pterocolidae, and Oxyrhynchidae. 



The superfamily Brachyceroidea has its type-genus Brachycerus 

 OHvier and contains the families Brachyceridae and Microoeridae. 



The superfamily CurcuUonidea is the old family Curculionidae, 

 based on Curculio Linnaeus {Balaninus Germar) of which the type was 

 designated by Latreille (1810) as nucum Linnaeus. It contains the 

 famihes PsaUidiidae (Brachyrhinidae) , Psahduridae, Plinthidae, Hy- 

 peridae, Curcuhonidae, Orobitidae, Cryptorhynchidae, Rynchophor- 

 idae (Calandridae) , and Cossonidae. 



The superfamily Scolytoidea (Ipoidea Swaine) is the old family 

 Scolytidse, and is based on Scolytus Geoffroy 1762. 



More complete discussions of these various families will be presented 

 from time to time. 



PSALLIDIIDAE, new family (OTIORHYNCHIDAE, 

 BRACHYRHINIDAE). 



Subfamily Psallidiinae (Brachyderini). 



TRIBE THYLACITINI. 



EXOPHTHALMODES, new genus. 



Exophthalmus (Schonherr) Champion (part), Biol. Centr. Amer. Coleopt., vol. 4, 

 1911, pt. 3, pp. 249-270 (not Exophthalmus Latreille). 



Champion has included in his genus Schonherr' s type quadrivit- 

 tatus Olivier, nicaraguensis Bovie and scalaris Boheman, all of which 

 undoubtedly belong to Diaprepes Schonherr, because of the presence 

 of vibrissae on the lateral anterior margin of the prothorax. 



Thirteen specimens of quadrivittatus , five of nicaraguensis deter- 

 mined by Champion, and 15 of scalaris have been personally examined. 



Other than these and possibly a few other species. Champion had 

 a distinct Thylacitine (Brachyderine) genus before him. Specimens 

 determined by him are at hand in the following species: verecundus 

 Chevrolat, cupreipes Champion, carinirostris Boheman, vitticollis
