GENERAL NOTES.
KOCH (I.e.) analyzes the geographical distribution of the
Lepidoptera at length.
He remarks on the difficulty of obtaining reliable information,
and then passes on to consider the five great zones of distribution
which he recognizes as distinct, as follows :—
1. The European or Western fauna (nearly corresponding to
Sclater's Palaearctic Region), distinguished by the genera Argynnis,
Melitma, Thais, Lyceena, Satyrus, Erebia, Zygeena, and
the Noctuce generally. Lepidoptera occur at all elevations (to
9000 feet in the Swiss Alps, and to 18,000 feet in the Andes).
\ anous North-American Sphinges and Noctua; have occurred
in Britain, which Koch supposes to have crossed the Atlantic
by flight [It may be remarked that all the North-American
species taken m Britain have been taken not in Ireland or in
