The author briefly sketches the entomological aspect of Cor- 
sica, especially as regards the likynchota. His deductions are : — 
1 , its poverty in species, and endless richness in individuals; 
2, that, as regards number of species, Corsica is surpassed by 
the neighbouring continents, and in a higher degree by any 
Swiss locality ; 3, that, as a whole, the peculiar conditions and 
flora of the island produce only a few peculiar insect-forms ; 4, 
that cultivation, from its result in Corsica, is likely to have an 
inordinate effect in dispersing insects to undisturbed loealities ; 
and, 5, that the inseet-fauna of Corsica is a mixture of southern 
French and Sicilian forms with those of Central Europe.
