tabulated below. Dr. Hanitsch had written, May 11, 1916 : 

 " All were caught on the wing, I am sorry to say, as I have 

 not yet been successful in breeding them. They are all from 

 Singapore Island, mostly from the residential part of the 

 town." 



The mimetic females were all of the polytes form with 

 white in the hind-wing cell. In three of those taken in 

 January and in one taken February 17 the submarginal 

 red spots of the hind-wing upper surface were, except at the 

 ends of the series, greatly reduced and some of them alto- 

 gether absent. There was, however, no corresponding reduc- 

 tion on the under surface, where the whole of the series re- 

 mained distinct and well marked. This form of the polytes 

 female represents a closer approach to the model; for in 

 aristolochiae the submarginal spots are dim and indistinct 

 on the upper surface of the hind-wing, but bright red and 

 startlingly conspicuous on its under surface. 



Dr. Hanitsch's results contrasted sharply with those re- 

 corded by Dr. Seitz, who found only the mimetic polytes 

 females at Singapore (Proc. Ent. Soc. Lond., 1913, p. xxxii.).
