Ml'. Williamson has a female from Bangnara, Pataui (wing 

 105 mm.), which is somewhat intermediate between this and the pre- 

 ceding form ; but is, on the whole, nearest to the southern race.

The only occurrences in our area are two males recorded by 



Mueller, and the pair obtained by Williamson in Patani. These 



latter, in their bright chestnut upper parts and pure white foreheads 



and eyebrows, represent the extreme development of tlie present form 



or phase. We have two examples from the Malay States resemblino- 



tliem — one from Pahang, the other from Kuala Lumpur.
