MIMICRY IN CEYLON BUTTERFLIES. 2h 
here the matter may be left until more experimental evidence is 
forthecoming.* 
It has been suggested above that the males of a species with poly- 
morphic females may be of different constitution with regard to the 
factors they contain, and with this in mind I have examined the 
series of males of P. polytes which I collected. There is considerable 
variation in the amount of the red marking and of the lunules of the 
hind wing. Two distinct forms can be readily picked out, viz., that 
in which the red is entirely absent and the lunules are much reduced 
(P1. 1., figs. 11 and 11 A) and that in which the lunules are relatively 
large and the red markings very distinct (P1.1.. figs. 10 and 10 A). 
Between these two extremes are found intermediate forms which 
cannot be sorted with the same certainty. Generally speaking, 
however, the intermediates fall into two groups: (a) those in which 
the lunules are large and in the hindermost at any rate furnished 
with some red scales, and (b) those in which the lunules are small and 
the red is confined to the spot by the tail. These I have called 
respectively Int. I. and Int. II. Inthe appended table I have, with 
the help of my friend Mr. J. C. F. Fryer, classified the available males 
according to their markings and the locality from which they came :-—

Several points of interest may be made out from this table. Very 
noticeable is the absence of really ‘‘ red’ 66 at Trincomalee, as 
well as the great preponderance here of 66 which show no red. 
While the hotter and drier climate of these parts may possibly 
lead to a general diminution of the red scales, this cannot be the 

* Since the above was written Mr. E. E. Green has succeeded in raising 
a brood of P. polytes from the ‘‘ male form” of female. All the females of 
this brood, 37 in number, were of the ‘‘male form,” a fact which is in 
harmony with the scheme suggested above. And here attention may be 
called to an important paper by J. C. H. de Meijere on Papilis memnon, 
which has recently been the subject of breeding experiments in Java. It is 
suggested that the data from the three forms of female are consistent with a 
Mendelian interpretation of this case. (Zeitschrift fur induktive Abstammungs 
und Vererbungslehre, 3 Heft, 1910.) It should be mentioned that all the 
three forms of female here are different to the male.
