EXPLANATION OF PLATE XL. 
All figures are just over } of the natural size. 
Females of three families of Papilio dardanus, Brown, bred by 
W. A. Lamborn from female parents, also represented in the Plate, 
captured in the Lagos district of W. Africa, 1911 and 1912. Parents 
and offspring are all of the hippocoén, F., form. 
The white mark in the cell of the fore-wing is clearly seen to 
be much shorter than the corresponding feature in the hippocodn 
offspring of a planemoides parent shown on Plate XX XIX. 
Slight family differences between the white patterns are also 
represented in the Plate. Figs. 10, 12, 13, and 14 are examples of 
Family A in which the white area of the hind-wing is increased by a 
circumferential greyish extension, barely visible in figs. 9, 11, and 15. 
In Family D the same white area, as shown in figs. 17-21, and 30, 
is larger and more angular in shape than in Family E, as represented 
in figs. 32, 33, and 38—differences which appear in the respective 
parents—figs. 16 and 31, and are clearly hereditary. Family 
differences between the fore-wings are similarly evident when 
careful comparison is made (p. 659).
