Extract

It appears from a reference to the literature, that the larvæ of less than 25 per cent. of the Tenthredinidæ listed as inhabiting the northeastern United States and Canada have been described. Of the Western species, scarcely half a dozen are known.

It seems desirable that something should be done to increase interest in this neglected subject, and I have thought it well to prepare a synoptic table of the larvæ already known, to facilitate the recognition of specimens and better indicate those as yet undescribed, and therefore needing study.

In the following table the Western species are excluded. If, by good fortune, any student of this group should arise there, he would find the field practically clear.
