Summary:
Sends specimens of Tortrix, which illustrate the extraordinary variation of markings in two or three species. In every family of Lepidoptera there seem to be species extremely prone to vary and in some localities they vary more than in others.

Have all varieties been bred from the same set of eggs so that there can be no doubt they are all the same species?

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.

Summary:
Has been interested in copy of HD’s letter to H. T. Stainton on numerical proportions of the sexes of insects. Do they vary during different years?
Does he have opinions about the courtships of butterflies?
Will send a copy of his paper on Primula when it is published. [See 5997.]

Summary:
CD asks about HD’s observation of sexual call of Coleoptera.
Also comments on statements by collectors that they breed more females than males from caterpillars. CD had thought this might be accounted for by the collection of largest and finest caterpillars, but Alexander Wallace says the collectors take large and small equally. Does HD agree with Wallace?
