The Canadian Entomologist
In the CANADIAN ENTOMOLOGIST, during the year 1898, I gave a series of papers on the classification of the horntails and sawflies, representing the superfamilies SIRICOIDEA (Xylophaga) and TENTHREDINOIDEA (Phyllophaga); while the past year, 1899, I gave a classification of the entomophilous wasps, or the superfamily SPHECOIDEA (incorrectly spelt Sphegoidca). The present year, 1900, with the permission of the Editor, it is my intention to give a similar series of papers on the classification of the superfamily VESPOIDEA, a large natural group, representing the genuine fossorial wasps, the papermaking wasps, potter wasps, and the predaceous, inquilinous and parasitic wasps.
