FATAL TEI\{PERATURE FOR DIASPIS AMYGDALI, TRYON. In the CANADIAN ENTOMOItrOGIST, Vol. XXX., pp. 78-80, the writer of this stated that a tree imported from Japan, and badly infested by this Coccid, had been transplanted to the insectary, but the other of the two trees mentioned was not, at that time, properly accounted for. It was planted outside, with a view of ascertaining the lowest degree of temperature that the Diaspis could withstand and not be destroyed. The lowest temperature reached in the winter of 1897-98 was-9o Fahr., but, notwithstanding this, the species wintered over in sufficient numbers to increase considerably over the previous year. During the winter of 1898-99, just passed, the temperature fell to-2I" Fahr. during a single night and to from-12o to -18o Fahr. for several successive nights, with the result that the Diaspis amygdali appear to have every one succumbed, as not a single living individual can be found on the tree.
