With the exception of some undetermined gallflies and parasites, the following list of 86 species contains all the Hymenoptera collected (and bred) by the author, in the South-west, of which it has proved possible to get the names, except four mentioned in Can. Ent., 1892, p. 200. The gallflies and parasites above referred to will be recorded in some papers to be published in the future. The cottonwood, Blennocampa, mentioned in Can. Ent., 1893, P. 304, and in Zoe, iii., pp. 234–236, should also be included in the above exception.
