Henry Denny

Henry Denny (1803 – 7 March 1871) was an English entomologist, known as an authority on parasitic insects.

Also in 1825, he published a monograph on the British species of ant-loving beetles in the genus Pselaphus.

The British Association for the Advancement of Science in 1842 made a grant to Denny for the study of British Anoplura; William Kirby tried to bring him in as illustrator of his Introduction to Entomology, and he contributed a few plates for it.

[3] A good friend of Charles Darwin, Henry Denny was asked if lice affecting humans could have speciated in different parts of the world.

Denny's response would be included in his treatise "The Descent of Man, and Selection in Relation to Sex".
