A smaller part of the species is represented by widespread tropic taxa, inhabiting mainly disturbed and/or secondary habitats, some of them are well-known agricultural pesta A group of this faunal type consists of Old World Tropic species, appearing both in Africa and Indo-Australia, from which one ( C. limbirena Guenée) has an Ethiopian centre and not reaches the eastern areas of the Oriental Region, the remained taxa ' A. signata Fabricius , T. orichalcea Fabricius and C. acuta Walker) are widely distributed in both continents. The second species-group contains the widespread Oriental species (C . eriosoma Doubleday, C. illuminata Robinson, T. intermixta Warren, T. lectula Walker and 7,. ochreata Walker), since the third group is represented by a sole species having an unusual, Palaearctic-Transpacific range ( C. albostriata) , this species shows the connection of the Indo-Australian and S American fauna. Only one species is known from Vietnam which has a Palaearctic centre of distribution Í C. agnata Staudinger), the southernmost part of its range is the northern territory of Vietnam. The complete list of species collected by the Hungarian expeditions, with the descriptions of the new species are given in the following chapter. LIST OF SPECIES Chrysodeixis chrysopepla sp. n.
