The eggs have also been examined; they were obtained by Dr. Tillyard from a female placed alive in a moist tube, on the wall of which she deposited them singly, the degree of adhesion being only slight. These eggs were fixed in spirit when of an average age of 19 hours; they present a beginning of segmentation. Their shape is that of a long oval, one end being slightly more pointed. They.
