The firstfemale weighed grams. This and the last female had a pre-oviposition period of 8 days at a mean temperature of 84° F. Thesecond female began depositing on the tenth day after dropping. 126 LIFE HISTORY OF NORTH AMERICAN TICKS. The deposition period of the first and second females was 21 and 16days respectively. The largest number of eggs deposited was 5,481;the average 3,839. Oviposition continued in one case for 21 days. Many of the eggs deposited by these females were black and shriv-eled when deposited and ultimately only a very small percentage ofthem hatched. It is believed that in nature several thousand moreeggs would be deposited, as the females observed by us were stillof large size w
