Superfamily ICHNEUMONOIDEA 487 



ruficornis (Ashmead). Mo.? The holotype bears a label with what is apparently the illegible 

 name of a collector and another label reading "Collection C. V. Riley;" as often as not, 

 Ashmead was incorrect concerning localities for specimens in the Riley collection.

 subtilicornis (Gravenhorst). Ont., Ohio, Ind., N. Dak., Kans., Utah, Wash., Oreg.; Eurasia. Host: 

 Phttella xylostella (L.). Cushman (1935) suppressed Herpestomus plutellae Ashmead as 

 a synonym of subtilicornis, and, after comparing North American and European 

 specimens, I have concluded that Townes (1944) was incorrect in resurrecting plutellae 

 from synonymy. Phaeogenes japonicus Ashmead was erroneously suppressed as a 

 synonym of subtilicornis by Townes, Momoi, and Townes (1965).
