30 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
genera are mostly different; thus the Brachyderini are represented by 
Liparus, Anisorhynchus, and Brachyderes, five species in all; the Otiorhyn- 
chidze by Otiorhynchus and Laparocerus, a half dozen species, all Pleistocene; 
the Tanymecini by Thylacites, a single species; the Cyphini by Naupactus 
and Strophosomus, a couple of species; and the Phyllobiini by Phyllobius 
and Polydrosus, in amber. We find, therefore, only 11 genera and 17 
species in Europe, against 23 genera and 47 species in America. The 
importance of the Otiorhynchidee in the American Tertiaries, and particularly 
in the Gosiute fauna, is therefore apparent. 
The following table will give in detail the peculiarities of this distribu- 
tion, by which it appears that the relative development of the different 
tribes in the recent American fauna is in this instance more nearly 
approached by the American than by the European Tertiary fauna.

Tribe BRACHYDERINI. : 
A half dozen fossil species of this tribe have been found in America, 
three species of Epiczerus, typical of the Gosiute fauna, and one species 
each of Hormorus, Trigonoscuta, and Tenillus, the last an extinet type, all 
from the Florissant basin, and so far as known peculiar to the Lacustrine 
fauna. In the European Tertiaries it was one of the most abundant tribes
