 which recessive remains unsettled. 



The first small family, bred in 1913 from the eggs laid by 

 the $ f. eihalion, produced males, 2 swynnertoni females and 

 I eihalion , of form b. The second family from the eggs of a 

 swynnertoni female produced 17 males and 14 females of the 

 same form as the parent. The tendency for the males to 

 emerge earlier is well shown in the tabular statement : — ■

 instead of being " white, slightly bluish proximally, and with 

 a faint trace of ochraceous at distal edge " (Rothsch. and 

 Jord., ibid., p. 486), is, in the typical form, orange-ochreous 

 throughout, thus transforming a mimic of the o ansorgei, 

 Rothsch., into a mimic of saturnus, Butl. This latter resem- 

 blance is also promoted by the tendency of the F.W. bar 

 in some individuals to broaden and suffuse the dark ground- 

 colour with orange-ochreous.
