which is covered with irregular masses of rock and overgrown with a dense, luxuriant, 

 but less lofty vegetation. We passed a torrent of water which is not much lower than 

 the boiling point, and has a most singular appearance as it foams over its rugged bed,

 and lycopodia, which here thrive with more luxuriance than elsewhere.' 



On i\Iount 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, Mi*. Owen Bryant 

 and Mr. William Palmer. The majority of the specimens, including 

 the holotypes and miiques, are m 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.
