THE BUTTERFLIES OF SIAM. 107 



Mj' own experience in the country extends over tlie last seven 

 j'ears. 



During these years I have collected in my spare time in the 

 following localities : — 



I. In Central Sum : The Bangkok district and the country to 

 the north as far as Lopburi. 



The City of Bangkok is situated on both banks of the Jlenam 

 Chao Praya in latitude 13''. 45' N and longitude 100°. 30' E. 

 On the west bank it is bounded by fruit gardens, on the 

 east bank by padi plains. The mean level of the city is only 

 from 4 to 6 metres above sea-level. The city itself is thickly 

 interspersed with fruit gardens. 



II. In South-eastern Siam : The Sriracha district. 



This district includes a strip of dry, sandj^ open jungle extending 

 along the sea-shore, and an inland forest area which rises 

 steadily to a height of about 200 metres. With the exception 

 of a few clearings and plantations this area is all dense ever- 

 green forest. The soil is sandy throughout, and few running 

 streams are to be found. The area is bounded on the east by 

 granite mountain ridges ranging from 300 to 600 metres in 

 height. Nong Yai Boo, Ban Dan, Nong Khor, Nong Khai 

 Ploi and Hup Bon are in this district. 



III. In Western Siam : The country near Kang Kra Chang on 

 the Petchaburi River up to a height of about 190 metres. 



This district consists of dense forest and jungle, the only open 

 spaces in the area being the small cultivated patches around one 

 or two small native settlements. The jungle is for the 

 most part damp and evergreen, with perennial streams running 

 in the valleys. The district is bounded on the north and west 

 by mountain ridges i-anging from 900 to 1150 metres in height, 

 and on the east by an intermediate area of less mountainous 

 country which divides the true mountains from the plains, and 

 which is covered with mixed evergreen and deciduous jungle. 



IV. In Eastern Siaji : At Hinlap, IMuak Lek, Pak Jong and 

 Chanteuk on the Dong llek range. 



The jungle near these places is mostly evergreen, but around
