Family CAT^AT^TDRID^E. 



This family w^as not very well represented in America in Tertiary times, 

 its proportion of species to the whole body of Rhynchophora standing some- 

 what below the present proportion. One of its existing subfamilies, the 

 Rhinina', represented ii\ America to-day by only a single species, is unknown 

 in both the Pkiropean and American Tertiaries, but the other two sul)families 

 occur in each country, and in proportions not greatly fliffering from those 

 now exi.stmg, though in l)otli countries the Cossonina? appear to stand a little 

 above, the Calaudrina' a little below, their present numerical importance. 

 The total number of fossil species known is sixteen, of which the larger 

 portion come from America. 



Subfamily CALANDRINyE. 



Of the thi'ee tril)es into which the existing American .species of this 



subfamily fall, the Khynchophorini alone are not represented in Tertiary 



dej)o.sits ; the other two arc found both in Hurope and America, but with 



more species in the latter. The Spheno])horiiii are as now, liut by no 



means to the sam(! extent as now, the nittst ninuerous.
