The duration of the egg, larval and pupal stages ofParischnogaster mellyi was established and the mean duration for the whole developmental sequence was found to be about 53 days. Evidence from larval head-widths suggested the presence of only 3 or 4 larval instars. Eggs were observed to be placed in the cell with the mouthparts. The unique white secretion which accompanies stenogastrine eggs and young larvae was observed to be produced from the tip of the gaster. The Dufour's gland is proposed as a possible source of the secretion. The number of males per nest was found to be positively correlated with brood size. A considerable proportion of the brood (84 %) was lost, the majority apparently through cannibalism by colony members. The maximum number of eggs+larvae that a single female could look after was found to be 8 or 9.
