12 TERTIARY COLEOPTERA OF NORTH AMERICA. 



The volume is, therefore, mainly a treatise oil the Adephagous ami 

 ( 'lavieorn < 'oleoptera of Florissant, Imt is at the same time a catalogue of 

 all hitherto known or here published non-rhynchophorous Coleoptera of 

 North America (26 families, 12f> genera, iMO species) As in the volume 

 on the Rhynchophora, I have prefixed to each genus and family a summary 

 of our knowledge of the extinct forms in the given group, brought up to 

 the date of writing (August, 1X96). 



I still retain the hope of completing the history of our fossil Coleoptera, 

 if not by extended memoirs embracing long .series, at least by the publica- 

 tion of more limited papers upon separate families. The material therefor 

 is vast, but other engagements prevent rapid execution of my desires. 



DESCRIPTIONS OF SPECIES. 



More than two hundred species of Carabidae have been found fossil, 

 referred to fifty-four genera, of which six are regarded us extinct. Thirtv- 

 two of these species, belonging to fourteen genera (of which onlv two are 

 not otherwise recorded as fossil), are referred to existing species and occur 

 only in the Pleistocene of Kurope. Omitting these, there are one hundred 

 and seventy-two fossil species, of which fifty-four (of twenty-four genera ) 

 belong to the Pleistocene, twentv-seven species of fourteen genera in tile 

 < )ld World, and the same number of species of ten genera in North America. 

 From the older Tertiaries, one hundred and eighteen species are known of 

 forty-four genera (six extinct), vi/, eighty-five species of thirty-four genera 

 (five extinct) in the ()ld World, and thirtv-three species of twentv-six 

 genera (one extinct) in the New World. No species have been found on 

 both continents. ( )f the fortv-four genera from the older Tertiaries, thirl v- 

 four are found in the Old World, nineteen in the New, and nine in both. 

 Fourteen genera are represented both in the older and latest Tertiaries.
