Tribe ANTHONOMINI. 



This tribe, now represented in .\merica l)y a considerable number of 

 sjjecies, though not rich iu generic types, and entirely ab.sent from Knropean 

 'I'eitiary deposits, is one of the most iinjjortant of the ( "urcidionina- in the 

 'I'eitiaries ot' America, the innnber of generic tvpes whi(di have been dis- 

 covered being as great as Jiow, KUesclius being the oid\ one not recognized, 

 and its place is made good by an extinct type, Creniastorhynchus, with a 

 single .species. Acalyptus, Orchestes, and .Macrorhoptus have ea(di a single 

 species, Coccotorus two, and all of these come exchisivelv from Florissant: 

 as in the existing fauna, however, Anthonomus is far the best represented, 

 being in fact the richest species of any ot' onr fossil Ulniichophora, having 

 ten species tolerid)lv niunerous in individuals, and all but two, which come 

 Iroin the Gosiute fauna, are like.wise restricted to Florissant.
