B (b) Showing egg of tarnished plant bug, Lygus praten- sis, L. oviposited through a bract on a strawberry stem. The eggs of this insect are laid in such a variety of ways that it is impossible to state any definite location in which they may be found. Thus in the early season eggs were found in the leaf buds of currants and later, as the leaves un- folded, in the petioles. On Mullein, eggs were found in the midribs and the larger leaf veins; on the night flowering catchfly, in the blade of the leaf; on strawberries, in the pedicel of the flowers; on ox-eye daisy, in the receptacle of the flowers; and on willow in the second year bark. The method of insertion also varies a great deal; in some cases the eggs are buried for their full length in the tissue; in others the egg may protrude for practically its entire length, or only a small tip may remain exposed; and occasionally they may even be found lying loose on a fold in the leaf. In regard to the regularity of their occurrence in the tissue, or the system of laying followed, there does not seem to be any rule. Eggs are usually found distributed singly though they may be in groups, as many as eight having been counted in a square centimetre on the midrib of a mullein leaf. Eggs of the overwintering adults were first taken on May 22nd, 1926; these eggs hatched in a few days and the nymphs reached maturity about the middle of July. The adults of these nymphs can, therefore, be called the spring genera- tion. In field observations eggs of the spring generation were noted in the follo
