The two Danaids together with the females of the other three species form a "mimicry ring." For explanation see text, pp. 65-69.

The specimens figured on this plate were taken in Ceylon where they are all plentiful. Figures 1a—6a represent the under surfaces of the hind wings belonging to specimens 1—6.

(Note. Pseudacraea hobleyi and P. terra (Figs. 6—8) were at one time regarded as separate species. More recently they have been shewn to be forms of the polymorphic species, Pseudacraea eurytus.)

(Note. The figure of the Mechanitis (Fig. 7) is taken from a rather worn specimen. The quality of the orange brown is better shewn by the specimen illustrated in Fig. 7 on Plate XV.)

(For further details of this case see Jordan, I^er Congr. Internat. d'Entomologie, Bruxelles, 1911, p. 396.)
