I/ab.—N. Territory: Batchelor (G. F. Hill, No.2). 

 A species readily distinguished by its palpi and general colour. 

 Apparently not closely related to other species of Group x. 



Group xi. Species with pubescence on the eyes (Therioplectes). 



Tabanus circumdatus Walker.

I refer two specimens before me, provisionally, to this species. 

 They agree with Miss Ricardo's note on the species, and also 

 bear some affinity to the description of T. postponens Walker, 

 which, Miss Ricardo states, it closely resembles.

Three specimens before me bear a striking similarity to this 

 species, differing only in having the annuli of the third joint of 

 antenna? black, the basal portion broad, with a shallow angle- 

 the frontal callus is slightly larger, with a short, stout, exten-
