Extract

On the 6th May, 1901, a cluster of 30 eggs of Cricigrapha Normani, Grt., was found by the writer. Six of these had been destroyed and the contents eaten, probably by some hemiptetrous insect. The eggs were laid in rows close together, touching each other, on the upper side of a leaf of Caulophyllum thalictroides, Michx., and formed almost a completed square, an average of six eggs being in each row. They looked as if they had just been laid. Yound maple, ash and birch trees were growing near by.
