Published 'Extraordinary quantity of Coccinellidae' in Zoologist 1847, 5 1898-99. This is probably the same William Allen who is listed in Entomologist's Annual in 1857 and 1860 as interested in Coleoptera and Diptera. At that time he lived at Western Terrace, The Park, Nottingham (A.C.F.Allen is also listed at this address interested in Hymenoptera). Horn and Schenkling (1928: 11) are surely incorrect in listing Allen's dates as 1793-1864 since these refer to William Allen the naval officer and artist. (MD 8/17, 9/22)).
