In the United States, Florissant furnishes the vast proportion of the 
Tertiary species in all the subfamilies except the Sitoninee, where two out 
of the three come from the Gosiute fauna; but it is curious to note one ex- 
ception in that all the species of the first tribe of Curculionin, the Phytono- 
mini, 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 told, they form only one-fourth of the whole number of 
species and represent only one-sixth of the genera. 
Subfamily SITONIN AE. 
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 group appears to have been represented in Tertiary times in about 
the same relative numbers as at present. 
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 number of species in North America, some of which are also 
inhabitants of the Old World, and nearly all are confined to the Pacific 
slope. It is weil recognized in the European Tertiaries, distinct forms
