Subfamily COSSONINyG. 



Although the Rhyncoliiu holds the middle place in point of luunbers 

 among the existing tribes ()f Co.ssonina' in .\inerica, it is mn-epresented 

 both in the European and American Tertiaries. The Dryo])hthorini and 

 Cossonini, very unequally represented now in .\nieiica, are both known in 

 our Tertiaries liy a couple of species, but onl\- one of them (and the richest, 

 the Cossonini) has been recognizecl in Furojie, where three .species occur.
