Extract

In a paper published during the war Reeks pointed out that the sawfly which has caused much damage in the forests of Canada for about twenty years is identical with Lophyrus hercyniae, described by Hartig in 1837. In the same work he proved that Hartig was correct in describing hercyniae as a species distinct from Lophyrus polytomus Htg. Enslin's view that the two species should be united under the name polytomus is quite wrong. Reeks has shown that important biological and anatomical differences exist between them. Benson erected the genus Gilpinia for the species polytomus and for allied species. Reeks was unable to examine the types of the two species, kept in the Hartig collection in Germany, and for that reason he sent to me some specimens of the “European spruce sawfly” from Canada, with the request that I compare them with the types in the Hartig collection. The results of my examination are as follows.
