Entomological Society of Ontario; Insect pests; Insects -- Ontario Periodicals. 126 THE EEPORT OF THE No. 36 The newly emerged winged form has the antennae and legs very light yellow, almost transparent; the eyes dark red and very conspicuous, the head, prothorax and abdomen rufous red, the mesothorax yellowish, streaked with red. The wings are crumpled up at first and dark green in colour, with the exception of the costal nerve, which is yellow. The green colour remains for some time after the wings are finally resting roofwise over the back of the insect. The waxy excretion does not make its appearance in any quantity until some twenty-four hours after the winged form has emerged from its pupal covering. Migration. Experiments were carried out in Stanley Park two years ago with the object of confirming the former observations on the secondary host tree. Opening galls were placed in cages along with fresh branches of Sitka Spruce.
