REPORT OF THE STATE ENTOMOLOGIST 2/5 The following account of the manner of oviposition of the Cicada is based on some interesting observations communicated to me in a letter by Mr. Ira H. Lawton, Superintendent of Schools at Nyack: After finishing one fissure the female moved slowly forward about two steps, depressed her ovipositor about 45°, and setting her saws in motion, first alternately and then simultaneously, rapidly penetrated the bark, but the ovipositor was soon elevated to .25°.

REPORT OF THE STATE ENTOMOLOGIST 2/5 The following account of the manner of oviposition of the Cicada is based on some interesting observations communicated to me in a letter by Mr. Ira H. Lawton, Superintendent of Schools at Nyack: After finishing one fissure the female moved slowly forward about two steps, depressed her ovipositor about 45°, and setting her saws in motion, first alternately and then simultaneously, rapidly penetrated the bark, but the ovipositor was soon elevated to .25°. After penetrating to the full length of her ovipositor and fining that chamber with eggs, she sv/ung a little to one side and through the same hole in the bark excavated the opposite chamber and filled it with eggs. The making of each chamber occupied a little over 20 minutes or a total of 45 minutes for the whole. During the cutting of a fissure, the saws made about 80 strokes to the minute, and after making four, the female would rest for a time. The head of the Cicadas w^s directed, in the main, from the tree but not invariably so, as some worked with their head toward the trunk of the tree. ^^ Fig. Sometimes fifty of these fissures maybe made by the same Cicada punctures female m a twig, provided it is suitable to her needs.

The time required for the hatching of the eggs has been variously stated at fifty-two days, forty-two days, and even so brief as four- teen days. The nev/ly hatched Cicadas are slender, grub-like creatures about one- sixteenth of an inch long (Fig. 6).
