GENERAL INDEX. 



The following General Index to the three volumes of DIPTERA, the first, second, 

 and fourth of ' Insecta Britannica,' contains the Generic names and Synonyms of the 

 text, along with most of those in Stephens' Systematic Catalogue, Curtis's Guide, 

 and the generic synopsis in Westwood's Introduction. Synonyms and Subgenera 

 are in Italics, but in some extensive groups of the text, as Anthomyia, it has not 

 been attempted so to reduce the groups, many of which must be ultimately admitted. 

 The large Roman numerals indicate the volume, the small ones the pages of the In- 

 troduction to the fourth volume, the Arabic numerals the pages of the rest ; but, 

 when preceded by sp., the number of some species, in the last-quoted page, which 

 exemplifies the subgenus or group. It has not been thought necessary to notice slight 

 differences of orthography in the names, unless where the name might in consequence 

 be out of sight in the place looked for.
