This is the natural-history result of an excursion taken in 
1866 by the author, who appears to have chiefly turned his 
attention to the Crustacea. Observations are contained in it on 
the geographical distribution of Acanthia lectularia, Pulex irri~

carius, and especially on the number of Phryganidee. It also 
contains a catalogue oi Lepidoptera taken near Petrosavodsk.
