human and bovine) lias any connection with the other facts ? 

 It is most noticeable in Ceylon. A fellow collector used 

 systematically to lay a trap on the sandy margin of a stream, 

 to attract specimens of several species of Cyaniris (Lycaenidae). 

 And I have seen large numbers of migratory Papilios (prin- 

 cipally jason and teredon) collected round damp spots on the 

 high road where the cart bullocks had been micturating. I 

 I have taken alciblades under similar conditions ; but this is 

 a very much shyer creature and never associates with the 

 common herd. 



" I am sorry that I cannot speak with certainty of the 

 species that were feeding on Manders's arm, but I do not 

 think that they were Hesperidae. I am almost certain that 

 Lethe drypefis was one of the visitors, and I think that Pyrameis 

 cardui was another." 



Urea was a constituent of perspiration, although usually 

 present in very small quantities, and it might well have been 

 the attraction in the observation recorded by Mr. Green. 

 In the Hesperidae, on the other hand, it seemed more probable 

 that the attraction was salt. 



Papilio polytes ROMULUS, Cram., from the extreme 

 SOUTH OF India and from the mainland opposite Singapore 

 Island. — Prof. Poulton said that he had recently been given 

 the opportunity of studying a long series of P. polytes collected 

 1905-16, by Mr. J. Williams Hockin, on the W. slopes of the 

 Ashamboo' Hills, from 6 to 40 miles N.W. of Cape Comorin. 

 The series, which was of great interest in relation to the 

 forms of the species recorded from Ceylon, was composed as 

 follows : — 



Males— 30. 



Male-like female (cyrus) — 1. 

 Aristolochiae-lUce female (polytes) — 12. 

 Intermediate female — 1. 

 Hector-like female [romulus) — 21. 



The single intermediate female had the fore-wings of polytes 

 and the hind-wings of romulus, with reduced red markings 

 outside the cell and traces of the pale scales of polytes within 

 it. The pattern was precisely the same as that of some of
