474 Miss G. Ricarclo — A Revision of 



many synonyms between these two authors. Since then a 

 few species liave been described by Schiuer and Thompson, 

 and a few okler ones were described by Wiedemann and 

 Fabricius. 



Most of Macquart^s species have been seen by me in the 

 Paris Museum through the kindness of TM. Bouvier, and in 

 especial of M. Surcouf, and compared with Walker's species 

 ill the Brit. Mus. Coll. 



The pagination here nsed for ^Macquart's Dipt. Exot. is 

 that of the original work, first pul^lished in Mem. Sci. Agri. 

 et Arts de Lille, 1838-1855 ; the one usually used is unfor- 

 tunately that ol' the reprint, which did not retain the original 

 pagination. Priority is given to Macqnart^s names over 

 those of Walker as a rule, as the descriptions appear the 

 best. Williston and Hiue are followed in placing the jienus 

 Lepfof/asfer in a sepai'ate subfamily and in the arrangement 

 of the subgenera of Asihifi. 



The species from Australia, New Zealand, and Tasmania 

 only, are described; those from other parts of the Australasian 

 Ecgion are, as a rule, merely given with their references. 

 Judging from Walker's species, not many of the species of 

 the continent extend beyond it. 



All types are in the British Museum Coll. unless otherwise 

 specified.
