474 Miss G. RicaiJo — A Revision of 



many synonyms between these two authors. Since then a 

 few species have been described by Schiner and Thompson, 

 and a few older 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 M. Bouvier, and in 

 especial of M. Surcouf, and compared with Wall^er's species 

 in the Brit. Mus. Coll. 



The pagination here used for Macquart's Dipt. Exot. is 

 that of the original work, first published in Mem. Sci. Agri. 

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

 tunately that of the reprint, which did not retain the original 

 pagination. Priority is given to Macquart^s names over 

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

 best. Williston and Hine are f'dlowed in placing the genus 

 Leptogasier in a separate subfamily and in the arrangement 

 of the subgenera of Asilus. 



The species from Australia, New Zealand, and Tasmania 

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

 Region 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.
