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 Blight, 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 inaria, 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 occasion-. The first of these is 

 the family of fifty inaria females bred in 1908 by Mr. Rogers 

 from an intermediate female parent, also from Etabai (Proc. 

 Ent. Soc, 1909, pp. xxxvi, xxxvii). This latter parent was 

 "intermediate between the type and the inaria form, hut on 

 the whole nearer the former . . . the whole of the female 

 offspring were inaria — not a single type form, not a single 

 intermediate. 1 The second ie the family bred in 1904 by 



Mr. <i. 1\ 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, I'.Mll. pp. 689, 690, Plate XXXII). 



Thus there have been bred from inaria or intermediate 

 females. first, equality of inaria (including intermediate) and 

 misipi iria alone ; thirdly, misippus alone. 



These results are consistent with the Mendelian relationship, 

 if we assume (1) that the intermediate female behav< 

 heredity like inaria, (2) that misippus is dominant over inaria, 

 ('.',) that the iirsl male parent was a I ote, the 



carried the tendency of i>i<iri<t, the third that of misippus.
