Aphidius montanus Ashmead, 1890. Colo. Biol. Assn., Bui. 1: 20. S. 

 nigripes Ashmead. N. B. s. to N. C, w. to Minn, and Kans.; B. C, Wash., Calif. Host: 



Acyrthosiphon solani (Kalt.), Amphorophora sp.. Aphis nasturtii Kalt., Dactynotus 

 ambrosiae (Thomas), D. erigeronensis (Thomas), Macrosiphiim albifrons Essig, M. 

 avenae (F.), M. creelii Davis, M. euphorbiae (Thomas), M. liriodendri (Monell), M. rosae 

 (L.), Myzus persicae (Sulzer). Exact host range not established, but apparently a 

 preference for Macrosiphum spp. Earlier associations of this species under the name 

 pulcher Baker or ervi pulcher as a parasite of the pea aphid apparently all refer to 

 pisivorus Smith. Specimens used by Smith (1941) to describe rosae Haliday in No. 

 Amer. are actually nigripes.

 from Europe. Host: Myzus persicae (Sulzer). 

 Bracon picipes Nees, 1811. Gesell. Naturf. Freunde Berlin, Mag. 5: 28. 9. 

 pisivorus Smith. No. Amer. Host: Acyrthosiphon pisim (Harris). Exact host range is not 



established for this species; earlier records of hosts other than the pea aphid apparently 

 refer to nigripes Ashm. This species has erroneously been considered a synonym of 

 pulcher; also, most of the specimens used by Smith (1941) to describe nigripes are 

 actually pisivorus.
