Historical Note:
The Division of Insects of the United States National Museum, reorganized in 1963 as the Department of Entomology, had its origin in the deposit of personal collections
in 1881 by Charles Valentine Riley, entomologist of the Department of Agriculture. The Museum became the depository for the national collection of insects. The chief entomologist
of the Department of Agriculture became honorary curator of insects in the National Museum, aided by an assistant curator on the museum staff. Many staff members of the Department
of Agriculture served as custodians, and thus the national collection of insects has become a joint enterprise of the Department and the Museum. Honorary curators were as
follows: Charles Valentine Riley, 1881-1894; Leland Ossian Howard, 1895-1927. Assistant curators (museum employees) were as follows: John Bernhard Smith, 1886-1889; Martin
L. Linell (aid), 1889-1896; William Harris Ashmeade, 1897-1908.
