FOREWORD

This monograph is the eleventh to be published in a series planned on the Bornean 'macrolepidoptera' superfamilies Cossoidea, Zygaenoidea, Bombycoidea (including Sphingidae), Noctuoidea, Geometroidea, Calliduloidea and Castnioidea. Parts will appear over the next few years as regularly as the vagaries of life permit. The parts printed and dates of publication so far are shown on the back cover.

The author is in frequent communication with the Heterocera Sumatrana team organised by Dr E.W. Diehl, and the two series of publications complement each other to provide, for the first time, fully illustrated reference works to a large proportion of the very rich South East Asian and Sundanian macrolepidoptera fauna. In turn, they complement a Japanese series on The Moths of Nepal, published as supplements to the journal Tinea.

The series is based on a large amount of recently collected material that gives some indication of habitat preference for the species concerned. Data on early stages and host-plants are being collated and reviewed.

Literature on the Oriental fauna is voluminous but often without illustrations and with poor, superficial descriptions. Synonymy presented often proves to be erroneous. Generic placements and higher classification are often found to be similarly superficial on close examination. This problem is dealt with more fully in the author's introduction for his taxonomic appendix to H.S. Barlow's Introduction to the Moths of South East Asia. This series on the moths of Borneo is seen as an opportunity to establish a fresh, more stable foundation for the study of the Indo-Australian tropical macrolepidoptera, an opportunity facilitated by access to the wealth of historical material held in The Natural History Museum, London, and other European Museums. The centralisation of this material is a boon for the comparative studies necessary to provide the stable foundation just referred to.

The reader must be prepared, however, for major changes to previously accepted generic, or even subfamilial placements. For example, in this part, the many species previously placed in the genus Euproctis are mostly distributed amongst more apposite genera, with description of a few new ones.

As the series is completed it may be revised, indexed and reissued in three or four bound volumes as a full reference work. A field guide incorporating the colour plates is also being considered. Negotiations are in progress in Malaysia to produce an Internet edition.
