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.
Comments on J. O. Westwood’s entomological nomenclature.
Discusses the organs for stridulation in Orthoptera [see Descent 1: 352ff].
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".
Finds no absolute differences in size of sexes of Copridae. Gives several other genera in which males are larger than females.
Confirms his view of stridulation organ of house cricket. [see Descent 1: 354–5.]
