Sinea diadema (Fabr.) is a predacious insect which, because of its wide distribution on our continent, its richness in individuals, and its dict of injurious insects, is of considerable importance as a beneficial insect. It winters as an adult and probably passes through two generations a season. Description of the eggs, the process of hatching, feeding of the nymphs, length of the nymphal stages and descriptions of the nymphal instars are given in this paper.
