Domingo 1110. In damp forests along Sig streams at low alti- 
tudes. A fine series of specimens of this very characteristic species 
matching in all respects our series of specimens from Panay. The 
species was previously known only from Panay.

British North Borneo, Kalabakan, Tawao, Bibuga, and Batu 
Lima, Wood 905, Villamil 246, Ramos 1198, 1632, 1661, 1878; 
1928, 1930. In damp forests along small streams at low altitudes. 
The fine series of specimens apparently represent the typical Javan 
form of the species, agreeing closely with Javan material and with 
the descriptions based on Javan material. I am inclined to believe 
that the Malay Peninsula form described and figured by King* as 
Blume’s species is specifically distinct.
