Book Description
Excerpt from Memoirs on the Coleoptera, Vol. 1 Another mistake frequently made, and a very serious one, is in assuming that nearly all exotic forms can be forced into the genera of purely European species. Some genera are common to Europe and America, but the isolation of the latter region since the middle Tertiary has sufficed for the evolution of many distinct types, so that at present there are a great many more endemic American genera than of those common to the two continents. The same remark applies as well to the species, the least resemblance between species of the two continents sufficing some superficial observers for a verdict of identity, which is false as a rule. There are some species common to America and Europe but not many, and they constitute an exceedingly small proportion of the whole number known; moreover virtually all such are likely to be cosmopolitan.
