Superfamily ICHNEUMONOIDEA 723 



laetatorius (Fabricius). Newfoundland (insular) w. to B. C, s. to Fla., s. Tex., and s. Calif.; 

 Mexico, West Indies, Brazil, Peru, Argentina, Chile; most of Old World. Host: 

 AUograpta obliqua (Say), Metasyrphus americanus (Wied.), M. perplexus (Osb.), M. 

 vinelandi (Curran), Paragus (Pandasyopthalmus) tibialis (Fall.), Pseudodorus clavatus 

 (F.), Spkaerophoria contigua Macq., Syrphus rectus 0. S., S. vittatifrons Shan. This is 

 probably the most frequently collected species of Ichneumonidae; it is certainly the 

 most widely distributed one. It usually reproduces thelytokously. Males occur 

 sporadically in the U. S.; Dasch (1964) studied males from 19 states from coast to coast. 

 He said that males are not known to occur outside the Nearctic Region.
