The Athenæum article [review of Variation, 15 Feb 1868, pp. 243–4] is a disgrace.
WSD will keep CD’s queries about Hemiptera in mind. Secondary sexual characters are certainly more marked in exotic than in British species.

Summary:
Sends a preliminary reply to CD’s query [5890]. Ten males to one female among captured micro-Lepidoptera. Six females to four or five males in those he has bred. HTS is aware this is diametrically opposed to information from [Alexander] Wallace and Bates, but the true proportion of sexes can only be ascertained by breeding.
