In this paper I give a revised key to the North American species of the genus Elasmus Westwood, with the description of one new species, and two new synonyms. I have also included a discussion of the reasons for considering the genus Elasmus to be the only presently known member of a sub-family Elasminae of the Eulophidae, rather than a distinct family Elasmidae.
