cenea (22 to 8), and, above all, the two remarkable leighi 
forms. In the numbers of ¢trophonius, 4 as against 3, and 
of hippocoon, 2 as against 3, there is a close resemblance 
between the two families. 
The 25 male offspring exhibit the transition usually 
found in Natal between a somewhat heavily marked sub- 
marginal band to the hind-wing and one in which the costal 
and inner gaps are clearly indicated. The series is a normal 
one with nothing remarkable about either of the extremes. 
Several of the cenea offspring exhibit the influence of the 
trophonius parent in the richer deeper tinge of the basal 
patch of the hind-wing—an effect which is particularly dis- 
tinct in Nos. 17, 6, 14, 1, 45, and 53, increasing in the order 
of these numbers. A similar influence of the trophonius 
parent upon the cenea offspring was observed in 1906 (Trans. 
Ent. Soc., Plate XVII, fig. 8, and Description, p. 313) and 
of hippocoon upon cenea in 1908 (Trans. Ent. Soc., p. 436). 
This parental influence upon the tint of offspring belonging 
to a different form is extremely interesting, especially when, 
as in most cases, no other visible effect is produced. 
In describing the spots of the fore-wing the terminology 
suggested in Trans. Ent. Soc., 1908, p. 433, is followed. 
The submarginal spots (a) (8) and (y) are normal in 15 
specimens. (a) is so minute as to be nearly invisible in 
23 and 41: it is wanting and (3) minute in 40 and 47: 
both are wanting and (y) minute in 1 and 54. The missing 
spots are present on the under surface of all these specimens. 
The apical spot (6) is wanting from both surfaces of 1, 45, 
and 53. 
All the spots of the fore-wing upper surface are white 
in 6, 15, 23, and 47, and in 17, 22, 27, and 42 except for a 
faint yellowish tinge of the inner marginal border of the 
principal spot (1). In speaking of “spots” I do not include 
the streak along the inner margin (in 15, 27, 42, 51, 55, 
and minute traces in a few others), or the extension down- 
wards and outwards from spot (1) into interspace 1) (in 
23, 27, 41, the right side of 15, and slight indications in 
several others). The above-mentioned markings where pre- 
sent in this family are invariably ochreous. (1) is darkest
