General Notes. 
Koch (/. c.) 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 distri- 
bution which he recognizes as distinct, as follows : — 
1. The European or Western fauna (nearly corresponding to 
Sclater^s Palsearctic Region), distinguished by the genera Ar- 
gynniSj Melitaa, Thais^ Lyccena, Satyy'us, Erebia, Zygcena, and 
the Noctuce generally. Lepidoptera occur at all elevations (to 
9000 feet in the Swiss Alps, and to 18,000 feet in the Andes). 
Various North- American Sphinges and Noctuie 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 in Britain have been taken not in Ireland or in
