Bishop Museum of Honolulu, Hawaii, to North Borneo, from June 24, 1962, through January 14, 1963. Most of the time spent in the then British Colony was devoted to collecting in lowland habitats. The chief collecting localities were in the vicinity of Quoin Hill on the Semporna Peninsula, and near Kalabakan. Approximately two weeks were spent in surveying the Tenom area. Additional work was done by the North Borneo Department of Agriculture after my departure, mainly by Antonio D. Garcia. ACKNOWLEDGMENTS I am indebted to J. L. Gressitt of the Entomology Department of the Bishop Museum for providing the opportunity for me to work on the expedition and to examine and report on the material collected. Without the help of the North Borneo Department of Agriculture, the success of our expedition would have been restricted. The Entomologist of North Borneo, G. R. Conway, was of great help with our logistic problems as was the Director of the Department, Mr. E. J. H. Berwick, and the Agronomist of Cocoa Research Station, Ed Wyrley-Birch. The Bombay Burmah Trading Corporation, Ltd., provided facilities and transportation at Kalabakan. Mr. Dai Rees of that corporation should be especially mentioned. Others who helped are: J. A. Comber, Ronnie Young, Mr. and Mrs. Horace Traulsen, Maureen Wyrley-Birch, and the Resident, Tawau, Mr. Peter Edge. The Conservator of Forests kindly provided the necessary permits for collecting.
