686 Mr. G. F. Leigh on Synepigonic series of 
The second female is represented on Plate XX XJ, Fig. 11. 
It is seen that the left hind-wing is somewhat crippled. 
The specimen is a typical white-spotted form of cenea, 
similar to female I. of the 1902 group, but having an even 
smaller development of the buff tint on the inner marginal 
border of spot (1). 
It is unnecessary to describe the three male offspring in 
detail; masmuch as the form of the band and the develop- 
ment of the gaps are clearly shown in Plate XXXI, Figs. 
12-14, It is obvious, on a glance at the figures, that the 
inner gap is open in two specimens (Figs. 13 and 14), and 
only interrupted by a faint imperfect band in the third 
(Fig. 12). The costal gap, although not entirely open in 
any specimen, is strongly indicated in all three. 
The condition of the band in the males of these two 
groups raises the question, which was previously suggested 
(see pp. 681, 682) by the dwarfed female represented in Fig. 
6, as to whether any of the conditions associated with breed- 
ing from the egg in confinement may not favour reversion 
towards the more ancestral form of meriones and merope. 
It must be repeated that this is but a conjecture which 
would require the examination of a longer series of captured 
specimens and a far larger number of bred specimens in 
order to confirm it. It is, however, suggested as a 
possibility in certain cases by a study of the limited amount 
of material at my disposal. 
The proportion of the various forms of the female in 
these two groups of offspring (1902 and 1903), and especially 
the absence of tvophonius trom both, raises an interesting 
question as to their proportion in nature, Existing records 
do not enable us to arrive at certain or exact conclusions, 
but the following data are sufficiently in agreement to 
justify a rough estimate. 
Mr. G. F. Leigh informs me that in a good season in 
the neighbourhood of Durban, from 25 to 30 males might 
be met with in a single day; but some of these would be 
the same insect encountered more than once. During the 
last season (1903) Mr. Leigh did not see more than 30 
females altogether, and of these 2 were the trophonius 
form. Inquiring the experiences of others in the same 
period of time, he heard of only one other specimen of the 
latter variety. 
Mr. G. F. Leigh recognizes a second form of hippo- 
coonoides with “chalky-white” markings similar to, and, as
