Conclusion: H. smyrnensis colonized eastern Sumatra (Deli) about 
sixty years ago, following forest clearing and other human activities. 
In Java there is even now no evidence that it has actually settled and 
further developments must be awaited. You could ask Wells how the spe- 
cies H. chloris and H. smyrnensis interact in Malaya. 
Yours sincerely, 
G. F. Mees
