ACKNOWLEDGEMENTS

The extensive freshly collected material available arose partly through the activities of the author under the auspices of the Royal Geographical Society - Sarawak Government Expedition and Survey of the Gunung Mulu National Park (1977-8), whilst financed by a Government Grant- in-Aid for Scientific Investigations administered by the Royal Society, and on a previous expedition (1965) to G. Kinabalu. Another large 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.

The taxonomic work was undertaken at the British Museum (Natural History) with the permission of the Trustees and with the assistance and support of the Department of Entomology, particularly the Macrolepidoptera Section. I am very grateful to Mr A. Watson and Dr I.J. Kitching for helpful discussions and comments on drafts of the text.

Dr. W. Thomas was kind enough to avail me of his findings on the Spilosoma group of genera during several discussions at the BMNH. He is currently working on a treatment of the Arctiinae for Heterocera Sumatrana.

The photographs for the plates were generously prepared gratis by Mr Bernard D’Abrera.

The series is dependent on the continuing support and energies of Mr. H.S. Barlow who also acts as a longstop for errors in the next (the blame for any that escape is mine)

Finally I would like to thank my wife, Phillipa, for once again taking on most of the burden of preparing the typescript amongst many other demands on her time.
