Extract

Two flies have emerged from cocoons which had passed two winters. Last summer I noticed an example of mistaken instinct. The eggs of this species are laid under the lower epidermis by saw-cuts in the edge of the leaf. Several eggs so laid were found on Ilex verticillata. In due time the larvæ hatched, but refused their food, and would undoubtedly have perished had I not recognized them and supplied them with willow, which they attacked voraciously.

* I propose this term for that final larval stage of certain sawflies in which they do not feed, but only seek for a place for pupation; the colour is usually markedly different from the preceding stage, but the head has the same width.
