 nortoni (Cresson). Newfoundland (Labrador) s. to n. Ga., w. to Alaska and Calif.; New 



Zealand, Australia. Ecology: Occurs in coniferous forests. Host: Urocenis albicomis (F.), 

 Xeris niorrisoni (Cr.), Sirex sp., S. noctilio F. These host records are North American, 

 except in the case of Sirex noctilio, which was the target species for the successful 

 introductions into New Zealand and Australia. It seems very likely that nortoni will, at 

 best, prove to be only subspecifically distinct from the Eurasian M. gigas (Laxmann).
