The present paper is in continuation of our previous one published in 

 These Proceedings (1920, p. 460). Certain additional information has in the 

 meantime come to hand regarding Australian species and has been incorporated 

 in the present paper. For much of this information we are again indebted to 

 Dr. Guy A. K. Marshall of the Imperial Bureau of Entomology. An examination 

 of the Tabanid types in the Queensland Museum has also revealed the necessity 

 for further alterations. 



The arrival of Surcouf's Monograph of the Tabmiidae (Wytsman's G<n. 

 Insect., Fase. 175, 1921) has revealed an extensive use of names, particularly 

 in the genus Tahanus, preoccupied by species in other portions of the world 

 Unfortunately a name (mmnsculus) we proposed in our previous paper to re- 

 place a preoccupied name (minor) is also . preoccupied, but as it is not given 

 in Kertesz's Catalogue, we overlooked its prior use. 



The following names appear from Surcouf's work to be preoccupied. Alter- 

 native names are proposed for these in the body of the paper. 



Tabanus confusus Taylor (1917) preoccupied by T. confusus Walker (1838) : 

 T. latifrons Ferg. (1921) by T. latifrons Zetterstedt (1842) =T. cordiger 

 Meigen; T. macquarti Ric. (1915) by T. macquarti Schin. (1868) ^T. bigoti 

 Bellardi (1859) ; T. meridionalis Ferg. (1920) by T. meridionaUs Thunb. (1827) ; 

 T. minusculus Ferg. & Hill (1920) by T. minusculus Hine (1907) ; and T. 

 pygmaeus Ferg. & Henry (1919) by T. pygmaeus Williston (1887). 



There also seems to be a prior use of Tabamis bifasciatitis, but the reference 

 is queried as follows : — 



144 "? T. bifasciatus Fourcroy (= ? Chrysops) Ent. Paris, Vol. 2, p. 450 

 (1785) Europe. 



This would appear to preclude the use of the name by Maequart (1834) r 

 but as the species has not been recognised in recent collections we do not pro- 

 pose to make any alteration in the name. 



Silvius notatus Ric. (1915) might also be regarded as preoccupied by 

 Diachlorus notatus Bigot (1893) a synonym of Silvius quadrivittatus Say 

 {Chrysops) (1823). In this ease also we do not propose to alter Miss Ricardo's 

 name, as Diachlorus notatus Bigot does not appear to have been known as Silvius
