From Henry Doubleday 5 February 1857
Summary
The variations of Peronea caused A. H. Haworth and J. F. Stephens to create 30 or 40 species based on colour and markings. HD was first to be convinced these would be reduced to two.
Discusses species that closely resemble one another;
cites species that differ in variation in different localities;
in some double-brooded species the broods differ markedly in size and colour.
Encloses his list of varieties of Peronea.
