Limneria salicicola Ashmead, 1890 (1889). U. S. Natl. Mus., Proc. 12: 437. 9. I believe that 

 the data which Ashmead gave for the holotype may not apply to it (see discussion of the 

 holotype of Diadegma acronyctae [Ashmead]).

 oculus (Viereck), n. comb. Ont., s.w. Alta. Host: Geometrid?, Operophtera bniceata (Hulst)? 

 The host records are queried because Geometridae seem unlikely to be hosts for 

 members of this genus.

This is a very large genus of worldwide distribution. Horstmann (1969) recognized three sub- 

 genera; he applied the name Nythobia Foerster to the largest subgenus. I am not convinced that 

 the name Nythobia should be applied to anything other than its type-species, N. pusio 

 (Holmgren).
