 in tlio Aiistialian Mnseiini, Sydney, which comprises one tiiindred and 

 twelve specimens repieseiiting forty-six s])ecies and four varieties 

 referable to seven genera. 



Twelve species and fotir varieties are described as new, while tlie 

 males of I'Jrc^^Jmpfiis ciiierHfi, Ricai'do, Diatowiliicnru piilcJnut, Ricai'do, and 

 'rnbtoius po.'^tpo^tei/s, AValker, are also described for the first time. Notes 

 on pi'eviously known forms are added where necessary. 



The new species are distributed in the followiiig genera : — En^/iJuiiisis 

 (two and one var.), Dintoniiveitnt (three), I'elecorhijiicJnn: (two), Sllviiis 

 (one), Ectevop^'is (one var.) and Tuhaiiiit' (four and two vars.). 



One synonym is noted and one name is changed, on the gi^ounds of 

 priority, though they have no connection with the material under review. 



The type specimens are in the Australian Museum. One paratype is 

 in the Institute Collection. 



This paper brings tlie number of known Australian Tabanidre to one 

 hundred and eighty-eight species and five varieties, which are distributed 

 in fifteen genera.
