Wollaston, Thomas Vernon (1821-78): Wollaston was an under-graduate at Jesus College, Cambridge, and in late life published several books on the coleopterous insects of Madeira, the Canaries, the Cape Verde Islands, and other regions. He is referred to in the "Origin of Species" (Edition VI page 109) as having discovered "the remarkable fact that 200 beetles, out of the 550 species (but more are now known) inhabiting Madeira, are so far deficient in wings that they cannot fly; and that, of the twenty-nine endemic genera, no less than twenty-three have all their species in this condition!"
