" Ph. hector is very common and so is the male P. polytes. 

 The two mimetic forms of female seem to be about equal in 

 numbers, but so far I have only seen one Ph. aristolochiae 

 model, and that we caught in the same place as the others 

 but on August 27. I thought I saw one on August 28, but 

 failed to capture it. It was flying fast and only settling out 

 of reach. The male P. polytes seem to be very much battered. 

 Would that be due to attacks by birds ? I have not observed 

 any such attacks yet. I have sent all that we caught with 

 the exception of a few which I have set here." 



Prof. Poulton said that Mrs. Fyson had sent the following 

 specimens of which examples were exhibited to the meeting. 

 The polytes female forms, with a large white spot in the hind- 

 wing cell, were, as was usually the case in India, transitional 

 by fine gradations into the stichius, Hiibn., female form, with 

 no white in the cell. 



The label referring to the catch of August 28 stated that 

 " the commonest forms were Ph. hector and the male P. 

 polytes.'' Inasmuch as a similar statement was made in 

 the accompanying letter (see above), it was evident that 

 the catches were directed to show the proportion between the 

 mimetic females but not between the romulus form and its 

 model; for only twelve of the latter to twenty-two of the 

 former were taken. The entire absence of the non-mimetic 

 form cyrus, Hiibn., of the female polytes from these catches 

 in Southern India formed an interesting contrast with the 

 proportions obtained by Mr. J. C. F. Fryer in Ceylon, but 

 corresponded with the experience of Mr. T. R. Bell in the 

 Bombay Presidency (Proc. Ent. Soc, 1914, p. xcix.). Prof. 

 Poulton hoped that the proportions of the female forms of
