Genus PIMPLA Fabricius 



Pimpla Fabricius, 1804. Systema piezatorum, p. 112. 



Type-species: Ichneumon manifestator Linnaeus. Desig. by Curtis, 1828. Members 

 of this genus parasitize aculeate Hymenoptera which nest in wood. My reasons 

 for using the name Pimpla rather than Ephialtes for this genus are given in the 

 introductory discussion of the Ichneumonidae. 

 brevis (Morley). Que., Ont., Man., Sask., Alta.; Europe. Host: Megachile sp., M. inerviis Prov., 

 M. nivalis Friese. 

 Ephialtes brevis Morley, 1914. Rev. Ichn. Brit. Mus., v. 3, p. 23. 9.

 102. 6, 9. 

 macra (Cresson). N. Y., Colo., Oreg., Calif. Host: Passaloecus sp. The host record given by 



Townes and Townes as 'W. brevicomis" is a mistake for Dendroctonus brevicomis LeC, 

 the pupal cells of which harbored the true host, Passaloecus sp. 

 Ephialtes macer Cresson, 1868. Canad. Ent. 1: 35. 9.
