CURCULIONID #®—CURCULIONIN ©—BARINI. 133 
e 
the most impertant tribes of Curculionine in the American Tertiaries. These 
genera are Baris, with four species, from Florissant; Aulobaris, with one 
species, from Florissant, and three from the Gosiute fauna; Centrinus, with 
two species, one each from Florissant and Green River; anda new generic 
type, Catobaris, with a single species, from Florissant. 
BARIS Germar. 
A genus exceedingly rich in species, of which over two hundred and 
fifty are catalogued. Although represented to a certain degree in nearly 
every part of the globe, America, possessing about three-fourths of the 
species, must be regarded as its proper home. By far the larger part are 
found in South and Central America, and the sixteen or seventeen species 
which North America possesses are found largely in the Southern states. 
The genus is not unknown in the Tertiaries. Long since Serres indicated 
its presence at Aix, in Provence, and Foerster describes one species, 
Baridium naviculare trom Brunstatt, Alsatia; while at Florissant, Colorado, 
no less than four species occur. Excepting B. divisa, all the species are very 
much stouter than the Brunstatt form, which has aso much stouter rostrum 
as to make it doubtful if all can be placed in the same genus. The 
species we have entered here are placed in this genus merely as typical of 
the group, but one, b. harlani, seems more stricly in place than the others. 
It is altogether probable that, were their characters fully known, they 
would have to be separated.
