Extract

Only a few studies have been made on the external morphology of both the adults and larva of a single species of sawfly, viz.: Hoplocampa balcyon (Nort.) (Bird 1926; 1927); Lygaeonematus subarcticus Forsl. (Forsslund 1936); Diprion pini (L.) (Arora 1953; 1959); Cephalcia marginata Middlekauff (Rivard 1955); and Taxonus agrorum Fallén (Ciampolini 1957). The following paper presents a detailed study of the external morphology of the larch sawfly, Pristiphora erichsonii (Htg.) and represents a consolidated revision of interim technical reports prepared earlier (Wong 1958a; 1958b). A recent paper by Bracken (1961) drew heavily from the wording and organization of the earlier of these reports for description of the external morphology of the adults of Anoplonyx luteipes (Cress.) and A. canadensis Harr. Unfortunately, Bracken incorporated minor morphological misinterpretations that have been corrected in the present paper.
