Etymology

The name honours "Mr. Ridley, a gentleman in the W African Coast Service whose love for our favourite science was displayed by a collection he made near the fort of Accra and sent to this country. He gave great promise of excelling in entomology, and fell a victim to the climate of W. Africa" according to Adam White, member of the entomological societies of London and Paris, assistant in the Zoology Department, British Museum, from: "Description of some apparently new Insects from the Congo, sent to England by Mr. Curror, Surgeon R. N., and the late Mr. John Cranch" (1843) Annals and Magazine of Natural History 12:262-268.

gollark: They do seem to have not very user controllable software.
