10. Papitjo demoleus malatanus Wall. 

 Common everywhere all the year i-ound. 



11. PaPILIO DEMOLION DEMOl.ION Cr. 



Not uncommon in the Sriracha district, but rare in other parts 

 of the country. 



12. Papilio chaon chaon Westw. 



Fairly common in all forest areas. Often found in numbers at 

 wet places in waterless beds of streams and in jungle paths. 



13. Papilio helenus helexus Linn. 



Is found in the same localities as the preceding, but is not so 

 common. 



14. Papilio hipponous pitmani Ehv. 



I took a few specimens of both se.ves of this butterfly on the 

 Petchaburi River in April 1910, but have not come across it since. 



Two of these specimens are now in the British Museum and are 

 the only e.xamples of pitmmii they have. 



The type oi pitmani came from the hills of South Tenasserim 

 below Tavoy, and it is onlj' natural that specimens taken on the Pet- 

 chaburi River should be of that form. 



In Eastern Siara, however, pitmani is replaced by the follow- 

 ing :— 



15. Papilio hipponous siamensis, subsp. nov. 



Resembles P. li. pitmani on the upperside but differs from it on 

 the underside as follows : — 



( 1 ). The discal band is pure white, not creamy. 

 (2). The lunular submarginal spots instead of being small and 

 uniformly brown are larger, brown centrally, paler e.x- 

 ternally and show a marked tendency to fuse at their ends 

 with the white marginal spots, especially in interspaces 4-7. 

 Types, from Pak Jong in the British Museum. 

 Common on the Dong Rek hills, especially at Pak Jong where 

 over thirty specimens were obtained in February. 



16. Papilio polytes polytes Linn. 

 Common everywhere all the year round. 



17. Papilio MEJiNOK AGENOE Linn. 



Males fairly common everywhere, females rare.
