This species by reason of its spotted wings is more easily 

 identified thau the other two species by the same author, and 

 has been found by Mr. Arthur White in Tasmania, who lias 

 kindly given a specimen to the Brit. Mus. Coll. 



My new species, Tabanus froggatti, is nearly related to T. 

 gentilis, both species having the same-shaped forehead, quite a 

 distinctive feature in them. This species is distinguished from 

 my species by its reddish antennas and legs ; the palpi are 

 also lighter in colour, and the hairs on the face and the 

 beard are more largely white than black. The chief differ- 

 ence is in the wings, which in this species are more distinctly 

 spotted, all the cross-veins on the upper part of wing having 

 dark spots round them.
