Unplaced Nomina Nuda of Ichneumonidae 



The following nomina nuda are not placeable in the synonymy of described species because 

 they have not been associated with particular specimens since they were pubHshed. Most of 

 them probably pertain to specimens which by now have been destroyed.

Family STEPHANIDAE 



By Robert W. Carlson 

 This small family is worldwide in distribution, but with species apparently most numerous in 

 the tropic and subtropic parts of the world. They are parasites of coleopterous and hymenop- 

 terous wood borers.

cinctipes (Cresson). Southwestern S. Dak., n. Idaho, and s. B. C. s. to s.e. Ariz, and s. Calif.; 

 Australia (Tasmania). Ecology: Kirk (1975) reared the species from Piiius ponderosa, 

 Picea engelmanni, and Abies concolor infested by species of Sirex, Urocerus, and Xeris. 

 The species has also emerged from Pseudotsuga menziesii. Host: Sirex noctilio F.,
