On ilount Pangerango, between 5,350 feet and the top, 10,000 feet, the number of 
forest trees is about 350 species on the same area (300 hectares or 3 square kilometers) 
and about 1,400 species of non-arborescent phanerogams.- 
ACKNOWLEDGMENTS. 
I am indebted to the collectors of the material, Mr. Owen Bryant 
and Mr. William Palmer. The majority of the specimens, including 
the holotypes and miiques, are in the United States National Museum, 
and Mr. Frederick Knab, the custodian of the Diptera, has kindly 
afforded me every opportunity for studying this material. Most of 
the remaining insects are in Boston in the private collection of Mr. 
C. W. Johnson, to whom I am grateful for many kindnesses, both at 
this time and often in the past.
