TACHINIDAE OF ORIENTAL REGION i 57 



of Mesnil stated in the original descriptions to be in Mesnil's collection are also now 

 in the CNC. Where it appears helpful such changes of custody are annotated 

 after the type-depository by a statement of the original ownership, e.g. 'ex coll. 

 Mesnil'. 



(5) Localities of extra-Oriental type-species. It may be conveniently noted here 

 that statements of the original provenance of the type-species of genus-group 

 names are given only for those names that are based on extra-Oriental type-species. 

 For example Enthera is based on a type-species from U.S.A. and Podotachina 

 is based on a type-species described from the Canary Islands (although now known 

 to be widespread) and the localities 'United States of America' and 'Canary Islands' 

 are entered in parentheses at the end of the relevant generic entries. Localities 

 are not given in the generic synonymies for the names based on Oriental-provenance 

 type-species, as the latter are listed with their type-localities in the catalogue of 

 species that accompanies each generic (or subgeneric) name. 



Geographical information. The scope of the Oriental Region for purposes 

 of the catalogue is defined in the Preamble (p. 5). The known distribution 

 of each species listed as valid is shown at least to the level of Oriental country, 

 and in the cases of China, India and Malaysia to the level of constituent state or 

 province; for Indonesia and the Philippines constituent islands are cited. Countries 

 and subdivisions within countries are listed alphabetically for the Oriental Region, 

 and any extra-Oriental distribution there may be is noted after the Oriental distribu- 

 tion; individual countries are not shown in cases of widespread extra-limital distribu- 

 tion. If there is only doubtful evidence for the occurrence of a particular species 

 in a country or island, either because reliable identification is not possible or because 

 a published record is suspect, then the area concerned is listed at the end of the 

 Oriental distribution with a query mark. 



The countries wholly or partly within the Oriental Region as defined are recorded 

 by the following names: Bangladesh, Bhutan, Burma, Cambodia, Ceylon, China, 

 Formosa, India, Indonesia, Laos, Malaysia, Nepal, Pakistan, Philippines, Ryukyu 

 Islands, Sikkim, Singapore, Thailand, Vietnam (North), Vietnam (South). The 

 old names Ceylon, Formosa and Celebes are used in preference to their modern 

 equivalents, Sri Lanka, Taiwan and Sulawesi. Spellings of Chinese place names 

 are those used in The Times Atlas of the World but alternative spellings have been 

 given additionally in a few instances where it is helpful for correlation with the 

 literature. 



Nomenclatural changes. Changes in nomenclature established in the cata- 

 logue are signified by the following abbreviations printed in bold type: Comb. n. 

 (new combination), Nom. n. (new name), Stat. n. (new status) and Syn. n. (new 

 synonym). Depending on the circumstances the initial letter of these abbreviations 

 may be lower-case or capital. The few names of new taxa described in this work 

 are marked with the usual gen. n. and sp. n. suffixes. New combinations are only 

 marked as such when considered taxonomically valid on present evidence; species- 

 group names that are assigned for the first time to a particular generic taxon are 

 not marked as new combinations if they are also junior synonyms (as in these
