Superfamily ICHNEUMONOIDEA 399 



Taxonomy: Slosson, 1896. Ent. News 7: 264 (the combination "Stiboscopus mandibularis 

 Prov." was almost certainly provided by Ashmead rather than Davis and was the first 

 inclusion of a species in Stiboscopus). — Viereck, 1911. U. S. Natl. Mus., Proc. 40: 193 

 (incorrect designation of Stiboscopus thoracicus Ashmead as type-species of Stiboscopus). 

 —Viereck, 1914. U. S. Natl. Mus., Bui. 83: 138 (oversight of first inclusion of species in 

 Stiboscopus as well as type-species designation by Viereck, 1911). — Townes, Townes, and 

 Gupta, 1961. Amer. Ent. Inst., Mem. 1: 123 (first inclusion of species in Lysibia).

 mandibularis (Provancher). Que. s. to N. C, w. to Oreg. and Calif. Host: Apanteles glomeratus 

 (L.), A. longricomis (Prov.), A. 7nelanoscelus (Ratz.), A. scitulus Riley, A. xylinus (Say), 

 A. yakutatensis Ash., Microplitus gortynae Riley. According to Townes and Townes 

 (1951) the Gravenhorst names fulvipes and nana have been erroneously applied to this 

 Nearctic species (L. nana being Palearctic).
