THE BUTTERFLIES OF SIAM. 127 



Up to 1914 I had taken only one specimen of this butterfly, 

 but in April and May of that year I met with it in great numbers 

 everywliere throughout the Sriracha district — in tlie jungle, in the padi- 

 fields, in the villages, and even on the sea-shore. In Sriracha itself, 

 the butterflies often entered the bungalows, and around the village they 

 were frequently to be seen clustered on lieaps of wood ashes. It is 

 interesting to note that I had collected in the district at various times 

 during the six previous years but had not met with the butterfly there, 

 and that in the same months of the following year I found it very 

 scarce everywhere throughout the district. Fruhstorfer gives javana 

 as the Siamese race, but I think this is a mistake. My males are 

 quite diflferent from his figure of javana, but agree exactly with 

 that of vasiiki, 



156. Hypolimnas missipus Linn. 



Apparently rare. I have only three specimens in my collection 

 — a male taken at Sriracha in September and two females given to me 

 by H. R. H. The Prince of Chumpon, who obtained them in Bangkok 

 in March. 



157. Hypolimnas bolina bolina Linn. 

 Fairly common everywhere all the year round, 



168. DOLESCHALLIA BISALTIDE SIAMENSIS Fruhst. 



Not common. Taken only in the Sriracha district and on 

 the Dong Rek hills. Fruhstorfer restricts this race to Siam. 



159. Kallima inachus siamensis Fruhstorfer. 



Occurs in most forest areas, but is nowhere common. Fruhs- 

 torfer restricts this race to Siam. 



160. Cyrestis periander periander Fabr. 

 Widely distributed and not uncommon. 



16 L Cyrestis cocles cocles Fabr. 



Widely distributed and quite common. Vast numbers of this 

 species were seen on the Petchaburi River in April and May 1910 and 

 again, in the same months, in 1912. The butterflies werealwa3-s found 

 on moist spots lying in shade, and, when disturbed, they rose in 

 clouds. In some places they were clustered so thickly, and were so 

 occupied in sucking up moisture, that it was quite impossible to tread 

 without crushing them. They were present in great numbers at all
