WALSH, Benjamin Dann, entomologist, born in Frome, Worcestershire, England, 21 September, 1808; died in Rock Island, Illinois, 18 November, 1869. He was graduated at Cambridge, and it was the desire of his parents that he should study for the ministry, his own inclinations led him into literary work, and he wrote extensively for periodicals, including a pamphlet on university reforms, almost all the suggestions in which he lived to see practically carried out. In 1838 he came to the United States and settled in Henry county, Illinois, where for thirteen years he led a secluded life, devoted to the care of his farm. His health becoming impaired, he removed to Rock Island in 1851, and there followed the lumber business for seven years. His active entomological career began after his retirement from business, and thereafter he contributed regularly from his observations and experience to various journals and proceedings of societies. In October, 1865, the "Practical Entomologist" was founded in Philadelphia, his name appeared as its associate editor from the west, and ultimately the editorial management passed entirely into his hands. During the session of 1866-'7 the legislature of Illinois authorized the appointment of a state entomologist, and Mr. Walsh's name was presented for confirmation. Although final action was deferred by the state senate until its next session, he discharged the duties of the office, and as acting state entomologist issued his first annual report for 1867. He was a member of various scientific societies, and was regarded as a standard authority on his specialty. His more important entomological works were published in the "Proceedings of the Philadelphia Entomological Society." Mr. Walsh was associated with Charles V. Riley in founding the " American Entomologist "in 1868, and was its senior editor until his death. In addition to the works that have been mentioned, he published " Walsh's Comedies of Aristophanes" (London, 1837).
