Thanks HWB for bringing "the question of sexes" before the Entomological Society. Feels he will come to some conclusion by comparison of numerous observations.

Thanks LA for information on sexual differences in the coloration of Amazonian fish. CD was anxious to know how the sexes differed because they are unusual in that the male has the largest share in looking after ova and young.
