Coloration in moths.
Quotes Achille Guénée on relative proportion of sexes in Phalaenites.
Thanks RT for letter which saves him from a "terrible mistake": that no moths were more brilliantly coloured beneath than above. Suggests revised version for comment. [See Descent 1: 397.]
Approves CD’s revision on coloration of moths.
Impressed with apparent adverse tendencies: one toward sexual selection, the other toward protection.
Extract from Émile Blanchard’s Metamorphoses, moeurs et instincts des insectes [1868], on attraction of males by female Lepidoptera, and possible explanation.
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.
Thanks CD for his orchid paper ["Fertilization of orchids", Collected papers 2: 138–56]. Comments briefly on orchids.
