Excerpt from An Index to Circulars 1 to 100 of the Bureau of Entomology For convenience the index itself is preceded by a list of circulars 1 to 100, with their revisions. This list may be considered as complete and final, since the policy of issuing revised editions of circulars, i. E., under the original serial number, has been discontinued and no more such will be published. Where circulars have gone through one or more revised editions the latest edition is the one indexed.
