CURCULIONID4—SITONIN 4. 67 
having been described from Aix (two species), Oeningen, and Rott. Three 
species are described below, one from Florissant, Colorado, another from 
Green River, Wyoming, and the third from both the Roan mountains, 
Colorado, and Green River, Wyoming, but this last species is referred here 
with much hesitation, and it may well belong to the Otiorhynchidx rather 
than the Curculionide. Our other species bear no close resemblance to 
any of those from the European Tertiaries.
