To Henry Doubleday 20 March [1868]
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?

To H. T. Stainton 2 March [1868]
Summary
Thanks HTS for his valuable information. Hopes to arrive at probable answer to question of proportion of males to females in the progeny of butterflies bred in domestication.
On courtship of butterflies, CD believes something more than chance is involved in determining which male is successful.

Wallace had not, in fact, written that a collector would be more likely to choose female caterpillars and later corrected CD on this point (see letter from Alexander Wallace, 14 March 1868 ).

In a letter to Stainton of 26 February 1868 , Henry Doubleday …

To Roland Trimen 14 April [1868]
Summary
Has tried using dealers’ price-lists as a guide to sex ratios in Lepidoptera; finds numerous cases in which the sexes bring different prices and in virtually all of them the males are cheaper. This seems to confirm the impression of the field collectors.
Wishes RT good luck with natural history in S. Africa.

Summary
In addition to the drawing of a caterpillar which CD intends to use,
HWB sends information on differences of colour and pattern between the sexes of species of Papilio.
Argynnis diana and A. sagana have females that are brightly coloured, but these may be cases of protective mimicry.
