Superfamily ICHNEUMONOIDEA 741 



Siricidae. Taylor (1967) developed a laboratory culture in Tasmania on Sirex noctilio 

 from field collected cinctipes adults shipped from Calif. Additional material was 

 imported from Ariz, and N. Mex., and cinctipes has been released and established in 

 Tasmania as a parasite of Sirex noctilio (Taylor, 1977, p. 430). S. noctilio does not occur 

 within the natural range of Schlettererius cinctipes.
