about f of the size of the other and the colours were much deeper. 

 A small female hatched out at about 6 p.m. on the 7th of .Septem- 

 ber. If touched, or otherwise disturbed, as by tapping on the 

 glass of the breeding cage while still in a tender condition, it 

 would emit a few drops of clear fluid from the vent. This was 

 not observed in P. hector. The wings as we have already remarked 

 became dry and stiff much quicker than those of the preceding 

 species.

Barkuda, g-ag-vii-ig ; i-6-ix-i9. 



Hab. — India, Upper Burma, China and Persia. 



Remarks. — Common during the "rains." It disappears al- 

 most completely in the dry weather, but fresh specimens appear 

 in large numbers within a day or two of the commencement of 

 the wet season, indicating that the species estivates in the pupal 

 stage.

Hah. — India, Burma and Cejdon. 



Remarks. — Jordan confines P. polytes to China giving the 

 Indian race as romulus, the name under which the hector-iika 

 female was originally described. Col. Evans writes us that the 

 names of the female forms should stand as follows : — 



Papilio polytei romulus, 2 /. cyrus, Fab. (resembling the 

 male of its own species). 



Papilio polytes romulus, 2 / polytes ,li\rm. (resembling P. am- 

 tolocliiae) . 



Papilio polytes romulus, 9 /. romulus, Cr. (resembling P. hec- 

 tor). 



Stichius, Hub. is a variety of the polytes 5 in which there is 

 no white cell spot on the hind wing.' 



Papilio polytes is perhaps the commonest butterfly on the 

 island at all seasons except the end of the dry weather, when 

 only a few battered individuals are to be seen. Its abundance is 

 due to a large extent to the abundance of the favourite food plant 

 of its caterpillar— G/ycoswjs pentaphylla. Unlike P. demoleus the 

 young brood of the early part of the " rains" does not appear 

 immediately on their commencement. Numerous young cater- ' 

 pillars were, however, observed on Glycosmis a few days after 

 the beginning of the wet weather in June, 1920, and it is probable 

 that the eggs of the winter brood do not hatch until the air 

 becomes damp. 



' This is somewhat contrary to the views expressed by him in his " r.ist," 

 (p. g72).
