Tribe OPHRYASTINI. 
With the exception of a couple of species, referred to Ophryastites as 
indicative of an alliance to Ophryastes, and which come from Florissant, all 
the fossil species of this tribe, relatively the most important of the family, 
are characteristic of the Gosiute fauna. They consist of four species of 
Ophryastes, two others of Ophryastites, one.of Exomias, and four of Phyx- 
elis. None of these genera have been elsewhere recognized in a fossil state. 
OPHRYASTES Schonherr. 
Excepting a single Siberian species, this is an exclusively American 
type, much more abundant in north temperate America than further south. 
The seven species found in the United States are all found in the western 
half of the continent. Four species occur in the western Tertiaries, none of 
them at Florissant, so that it would appear to be peculiar to the Gosiute 
fauna.
