Summary:
Has often thought CD would find vast material for his ideas in study of entomology and Lepidoptera. His price-list of specimens proves only that collectors of Lepidoptera catch more males than females, not that there are more. He accounts for this by the less active habits of the females. [See Descent 1: 312.]
