Tribe Sphecophagini Figure 21b Members of this tribe are parasitic in the nests of Vespula andPolistes. The mandible is characteristic with its long slender blade bearing arow of fine teeth along the entire length of the dorsal surface. Sphecophaga thuringiaca Schmiedeknecht (BM) (fig. 21b) andSphecophaga sp. (CDA) were examined. Sphecophaga vesparum (Curtis) is figured by Beirne (1941) andSphecophaga sp. by Snodgrass (1935).
