The addition of Xenopsylla cheopsis, proved vector of plague and endemic or murine typhus, to the known fauna of Iowa was made by Roudabush and Becker (1) in 1934. It was believed at the time to be the first collection of that flea in the interior of the United States, but there existed several previous records which, strangely enough, had been generally overlooked, principally because the reporters had not pointed out the implications of their findings, and because of their inclusion in official reports rather than in widely circulated journals. As was claimed by Roudabush (2) and as several new records presently to be introduced indicate, the flea is well-established in interior localities. Furthermore, the records prove that the flea had penetrated far inland as early as 1908 and 1910, and recent collections over a widespread area suggest that it will persist here indefinitely.
