 Lacoe. 



Tribe OPHRYASTINI. 



With the exception of a couple of species, referred to Ophryastites as 

 indicative of an alliance to Ophry<i.stes, 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 sjjecies, 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, su that it would appear to be peculiar to the Gosiute 



fauna.
