S ummary . 1. It is found that in the development of T. tabaci the degree of atmospheric humidity is of great importance in the question of the survival of the larva. 2. At high temperatures a relatively high degree of atmospheric humidity (over 70 per cent.) is necessary if the insects' are to reach maturity. 3. Although temperature has a most marked effect on the length of the life cycle of T, tabaci , the degree of relative humidity appears neutral, neither accelerating nor retarding the development of this insect.
