BARIS Gerinar. 



A genus exceedingly rich in species, of which over two hundred and 

 fiftN' are catalogued. Although represented to a lertain degree in nearly 

 every part of the globe, America, possessing about three-fourths of the 

 species, must be regarded as its ])roper home. \'>y far tiic larger part are 

 found in South and C!entral America, an<l tlic sixteen or seventeen species 

 which North America possesses are found largely in the Southern states. 

 The jrenus is not unknown in the Tertiaries. Lonj^ since Serres indicated 

 its presence at Aix, in Provence, and Foerster describes one species, 

 Baridium uaviculnre from Brunstatt, Alsatia; while at Florissant, Colorado, 

 no less than four species occur. F,\cepting B. (livisa, ;dl the species are very 

 much stouter than the Brunstatt form, which has a so nmch stouter rostrum 

 as to make it doubtful if all can l)e placed in tiic same genus. The 

 species we have entered here are placed in this l;cMius mcrcK as t\ pical of 

 the group, but one, 11. Iidrldiii. seems moiv stricly in jilace than the others. 

 It is altogether probable that, were their characters fully known, they 

 woiilil have to be separated.
