Born in Pilton, Somerset. Entered the Coldstream Guards as a private at an early age and eventually rose to the rank of Captain. Subsequently resigned his commission and moved to London, Ontario where he became engaged in the book trade. From thence he moved to the United States and settled in Brooklyn where he spent the last years of his life in the same branch of business.
Andrews devoted his leisure time chiefly to the pursuit of entomology. His publications mainly concerned Lepidoptera but he did write notes about the Potato Beetle in Sci. Gossip, 11, 1875, 161 and 14, 1878, 1-2,118-119, and also published 'Elytra of Dytiscus and Acilius' in Psyche, 21, 1883, 126.
He had ‘a well arranged collection of Coleoptera and Lepidoptera, and a small but well selected library of entomological works’ (Canadian Entomologist, 10, 1878, 240. Also in Report Entomological Society of Ontario, 10, 1879, 35-36). These accounts mention that his collection and library were purchased after his death by John Akhurst of Brooklyn, but Horn & Kahle (1937) notice that his collection passed via L.R. Reynolds to Fr. J. Psota of Chicago. (MD 1/22)
(Note: there have been and, indeed, still are many important entomologists with the names Andrewes and Andrews. Because their names are frequently mis-spelled, even in obituary notices, I have had great difficulty sorting them out. I hope that I have interpreted the material correctly and that the three listed were the main coleopterists).
