Abstract.4Two new species of Torymoides are described: T. comicus Grissell and
T. tragicus Grissell. Each is illustrated and a key is given to described Nearctic
species. The new species have not been reared. but 7. comucus may be associated with
insects infesting flower heads of Asteraceae or galls on Fabaceae. The new species are
reported from Arizona, western Texas, and central Mexico (Michoacan).
