The two species described herein bring the total number of known species of New World Cyrtinini to 17. Since the descriptions are scattered and no key to these species Gas previously available, a brief key to the genera and species in the tribe is presented, being based in part on the descriptions only. I examined the species of Haldeman and Fisher, but not those described by Pascoe, Gahan, Hope, Bates, and Cameron. References to the original descriptions are given by Leng (1920, p. 281) and Blackwelder (1946, pp. 619, 620, and 1957). In Blackwelder's 1946 work the date given for the description of Sciocyrtinus Fisher on page 620 should read 1935 instead of 1934. I wish to thank Mr. W. S. Fisher, Washington, D.C., for checking the key and examining specimens of the new species.
