 By Gertrude Ricardo. 



[Concluded from p. 40.] 



The genera Silvius, Chrysops, and Ectenopsis are included 

 in this paper, with four new genera, all in the Pangoninaj 

 division of the Tabanidse, and, with the last group of the 

 Tabanime, comprising the subgenus Therioplectes, added, 

 concludes the work on the family of Tabanidse. 



More material to add to the Brit. Mus. Coll. will he most 

 welcome, and will be gladly identified by the writer of this 

 paper.

The species of Silvius as yet recorded from Australia 

 are : — 



Silvius marginatus, ? , Walker. 



? Silvius nitesceus, J , Walker. 



Silvius silvester, Bergroth. 



Silvius marsoni, Summers.

Silvius lurida, Walker, described by him under Pangonia. 



To these four new species are now added. 



All the old species are represented in the Brit. Mus. Coll. 

 except Bergroth's species, of which 1 have no knowledge ; it 

 is described as from Central Queensland, a small blackish 

 species with two black-brown discal spots on the abdomen.

This female type in the Verrall Coll. is not a Tabanus 

 species, but apparently a species of Silvius, though, the
