The species known in America as the European spruce sawfly has been shown to be one of two species which have been confused under the name Gilpinia polytoma (Hartig) (1). One is arrhenotokous and is known only from Europe, and the other is thelytokous and occurs in Europe and America. This paper seeks to establish the correct nomenclature and provide adequate descriptions of the two species.

As a result of further studies of Eupithecia species chiefly in connection with their genitalia, the following notes have accumulated. As they may be of some certain interest to other workers in the group, I am publishing them at the present time.
