The island of Sibuyan is centrally situated in the Philip- 
pines, south of Luzon, east of Mindoro and north of Panay. 
It is for the larger part made up of the mountain mass of Giting- 
giting, the summit of which has never been reached. Mr. Elmer 
has here collected about forty species, including several hitherto 
known from but one or two collections, and the novelties deserib- 
ed below. The rarities are mostly species previously known 
only from Palauan.
