THE GENUS CALLIHORMIUS ASHMEAD (Hymenoptera: Braconidae) Paul M. Marsh, Entomology Research Division, ARS U.S. Department of Agriculture, Washington, D.C. Ashmead ( 1900, p. 148 ) characterized the genus Callihormius only as he included it in his key to the Ichneumon oidea, placing it in his subfamily Spathiinae, tribe Hormiini. However, CaUihormius belongs in the subfamily Doryctinae, tribe Doryctini, as I have defined it (Marsh, 1965). In the present study, I have interpreted the genus in a broader sense than has been done previously. For instance, one of the species described below, stigmatus, has a stigma in the male hind wing; my earlier diagnosis of the genus indicated that no stigma is present in the male {ibid., p. 697). The presence or absence of a stigma in the hind wing has been given generic value, but I believe that, as more genera of the Doryctinae are critically studied, this character will not always be generically significant. Callihormius contains five Nearctic species, four of which are de-scribed as new. The known hosts include larvae of beetles of the families Buprestidae and Cerambycidae.
