National Park (1977-8), whilst financed by a Government
Grant.in.Aid for Scientific Investigations administered by the Royal

part of this material was accumulated and prepared by Col. M.G. Allen and
Mr T.W. Harman during a series of expeditions in Brunei. I am grateful to
Prof. Dr L.W.R. Kobes for access to the Sumatran material collected by Dr
E.W. Diehl and others, the basis of the Heterocera Sumatrana Society
