Taxonomy of Cocoons and Puparia, and their Contents, of Canadian Parasites of Diprion hercyniae (Htg.) (Hymenoptera: Diprionidae)

Abstract

This is the second in a series of papers on the taxonomy of the cocoons and puparia, cast larval skins, and other remains of parasitic Hymenoptera and Diptera that are found in or near the remains of parasitized hosts after the parasites have emerged. The structures of taxonomic significance in the separation of the species were described and discussed in a previous paper (Finlayson, 1960). The present paper deals with the known Canadian parasites of the European spruce sawfly, Diprion hercyniae (Htg.). Parasites of D. hercyniae that were dealt with in the previous paper are not described or illustrated here.
