Asks about proportions of male to female insects.
CD in utter confusion about differences between J. O. Westwood and HWB on division of certain insects. Asks if HWB will homologise certain families for him, telling him which terms would be most generally understood.
Asks also about differences on sound-producing organs of Achetidae Gryllidae.
Thanks HWB for bringing "the question of sexes" before the Entomological Society. Feels he will come to some conclusion by comparison of numerous observations.
It appears Pangenesis "will expire unblessed and uncursed by the world".

CD has questions related to colour differences in the sexes of butterflies, especially in relation to HWB’s paper ["On variation in sexes of Argynnis diana", Proc. Entomol. Soc. Philadelphia 4 (1865): 204–7].
Mentions that his MS on Lepidoptera [for Descent] is longer than he intended and the information is four-fifths owed to HWB.
Thanks HWB for answering questions.

He extends an invitation for a Sunday in early June.
