1 Xenylla grisea Axelson and Lepidocyrtus cyaneus f. cinereus Folsom were reared on brown whole wheat flour in culture jars containing a base of plaster of paris and charcoal. 2 Sexes in X.grisea may be differentiated by the combination of three characters: length, colour and body shape. No parthenogenesis was observed in either species. 3 At room temperature (25–27°C), females of X.grisea began laying eggs after the fourth moult and required 10–15 days (mean of 12.6) to reach sexual maturity from the day of hatching. With L.cyaneus f. cinereus , average periods from hatching to maturity were 16.8, 27.4 and 43.2 days at temperatures of 26.5, 22 and 15°C, respectively.
