Abstract
A comprehensive account is given of the life-history, apparently not previously known, of the South African Lycaenid butterfly, Phasis zeuxo zeuxo (L.), with systematic descriptions and clear black-and-white figures, including details drawn under magnification, of the various stages.
The honey-gland and the function of the retractile tubercles of the larva are discussed in the early portion of the paper. All the stages, including each larval instar, are recorded separately. Observations are given on the habits of the larva and the imago, with reference to the time of appearance and flight-period of the butterfly and the probability of its being single-brooded. Localities are noted, and the recently ascertained extensive range of the butterfly eastwards of Cape Town is mentioned.
