 By Gertrude Hicardo. 



[Concluded from p. 40.] 



The genera Silvius, Chrysops, and Ectenopsis are included 

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

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

 Tabauiuce, comprising the subgenus Theriopledes^ added, 

 concludes the work on the family of Tabanidse. 



More material to add to the lirit. Mus. Coll. will be most 

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

 paper.

The species of Silvius as yet recorded from Australia

Silvius lurida. Walker, described by liim under Pangonia. 



To these four new species are now added. 



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

 is described as from Central Queensland, a small blackish 

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

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