An account is given of incubation experiments carried out on egg samples collected from twenty egg deposits in the outbreak area of L. pardalina. The majority of the eggs (95-100 per cent.) were in diapause, showing that the eggs produced by females in incipient swarms may enter diapause to the same degree as those laid by solitary and transiens individuals reared in the laboratory. Some aspects of the practical significance of these eggs and the presence of BHC on the viability of the eggs are discussed.
