HEREDITY IN THE FemMaLe Forms or HyrouimNas MISIPPUS. 
—Professor Pouiron exhibited a series of thirty-five females 
of the type form, together with their female parent, of the 
inaria form, captured Aug. 15, 1910, by Rev. K. St. Aubyn 
Rogers, M.A., F.E.S., at Rabai, near Mombasa. The males 
were liberated and the females emerged from the pupa on the 
following dates :— 
Sept. 15, 1910—sixteen, 4 with a slight, 2 with a rather 
more pronounced white patch on the hind-wing ; Sept. 16— 
nine, 1 with slight, 2 with more pronounced white patch ; 
Sept. 17—eight, 5 with slight indication of the patch; 
Sept. 18—two, 1 with slight indication of patch. 
The female parent is a typical ¢naria, with no indication of 
the white patch on its hind-wing. The female offspring were 
all typical misippus. 
This result compares in a most interesting manner with 
those obtained on two other occasions. The first of these is 
the family of fifty inaria females bred in 1908 by Mr. Rogers 
from an intermediate female parent, also from Rabai (Proc. 
Ent. Soc., 1909, pp. xxxvi, xxxvli). This latter parent was 
‘intermediate between the type and the inaria form, but on 
the whole nearer the former ... the whole of the female 
offspring were inaria—not a single type form, not a single 
intermediate.” The second is the family bred in 1904 by 
Mr. G. F. Leigh, F.E.S., from an intermediate female captured 
in the Durban district. Of the eight female offspring four 
were typical misippus, three typical inaria, and one inter- 
mediate (Trans. Ent. Soc., 1904, pp. 689, 690, Plate XX XII). 
Thus there have been bred from inaria or intermediate 
females, first, equality of inaria (including intermediate) and 
misippus ; secondly, inaria alone; thirdly, mzsippus alone. 
These results are consistent with the Mendelian relationship, 
if we assume (1) that the intermediate female behaves in 
heredity like ¢narva, (2) that misippus is dominant over inaria, 
(3) tnat the first male parent was a heterozygote, the second 
carried the tendency of inaria, the third that of misippus.
