EXPLANATION OF PLATE XXXII. 
All the figures are represented slightly more than half the natural 
size. . 
Two Synepigonic Groups of Papilio cenea together with their 
parents—a cenea form and a trophonius form respectively. 
Fia. 1. The female parent of the 1902 group, captured in copula 
with the male represented in Fig. 2. The butterfly 
represented in Fig. 1 is a typical white-spotted Natal 
cenea form. A selection of the female offspring is shown 
in Figs. 3-8. 
2. The male parent. The prominent black band of the hind- 
wing is rather less heavily marked than is usual in 
Southern forms. This feature was inherited by the male 
offspring. 
3. Female offspring of the cenea form described as IIT. in this 
memoir. A white-spotted Natal form showing some 
transition towards the buff-spotted variety. 
4. Female offspring of the cenea form, described as V. Rather 
more transitional towards the buff-spotted form than ITT. 
Dwarfed female offspring of the cenea form, described as 
IV. Intermediate between the females represented in 
Figs. 3 and 4, 
6. Much-dwarfed female offspring of the cenea form, described 
as VI. The specimen represented is nearest to the 
typical buff-spotted Southern form of female ceneq. 
7&8. Two female offspring of the hippocoonoides form, Both 
typical except for their stunted size, especially marked 
in Fig. 7. 
9. The female parent of the 1903 Synepigonice group captured 
near Durban on Sept. 18, 1903. It is seen to be a 
typical trophonius form. From this female seven eges 
were obtained, yielding the five imagines represented in 
Figs. 10-14. 
10. Female offspring of the cenea form: a white-spotted variety 
similar to the female described as IT. in the 1902 family. 
The chief spot (1) of the fore-wing is unusually small. 
11. Female offspring of the cenea form: a typical white-spotted 
variety similar to I. of the 1902 family. 
12-14. The male offspring.
