111 the United States, Florissant furnishes the vast proportion of the 

 Tertiary species in all the subfiimilies except the Sitoiiina', where two out 

 of the three come from the Gosiute fauna; V)ut it is curious to note one ex- 

 ception in that all the sjiecies of the first tribe of Curculioniiuv, the Phytono- 

 inini, and nearly all those of the second, the Hylobiini, also come from the 

 Gosiute fauna. The other species of the Gosiute fauna are scattered here 

 and there, but, all tdld, they form only one-fourth of the whole number of 

 species and represent only one-sixth of the genera. 



Subfamily SITONIN^E. 



As Sitona alone represents this subfamily among- the fossils the reader 

 is referred to that genus for general remarks. It may only be mentioned 

 that the g-rouj) appears to have been represented in Tertiary times in about 

 the same relative numbers as at jiresent. 



SITONA Germar. 



This genus, rich in species, is confined to the northern hemisphere, and 

 IS especially at home in Europe and the neighboring regions. There are a 

 considerable numljer of spccicis in North America, some of which are also 

 inhabitants of the ( )ld World, and nearly all are confijied to the Pacific 

 slope. It is well recognized in the Euro})ean Teitiaries, distinct forms
