TERTIARY RHYNCHOPHOROUS COLEOI'TERA. 



genera are mostly different; thus the Brachyderini are represented by 

 Liparus, Auisorhyuchus, and Brachyderes, iive species in all; the Otiorhyn- 

 chida? by Otiorhynclms and Laparocerus, a half dozen species, all Pleistocene; 

 the Tanyinecini by Thylacites, a single species; the Cyphini by Naupactus 

 and Strophosomus, a couple ot" species; and the Phyllobiini by Phyllobius 

 and Polydrosus, in amber. We find, therefore, only 11 genera and 17 

 species in Euro})e, against 23 genera and 47 species in America. The 

 importance of the Otiorhynchidre in the American Tertiaries, and particularly 

 in the Gosinte fauna, is therefore appai-ent 



The following table will give in detail the jieculiarities of this distribu- 

 tion, by which it appears that the rehxtive development of the different 

 tribes in the recent American fauna is in this instance more nearly 

 approached l^y the American than by the Em'opean Tertiary fauna.

Tribe BRACHYDERINI. 



A half dozen fossil species of this tribe have been found in America, 

 three species of Epicferus, typical of the Grosiute fauna, and one species 

 each of Hormorus, Trigonoscuta, and Teiiillus, tlie last an extinct type, all 

 from the Florissant basin, and so far as known peculiar to the Lacustrine 

 fauna. In the European Tertiaries it was one of the most abundant tribes
