Wales ; and Clevelaiul, Tasmania (Dr. J. L. Purdy) ; with 

 the following note attaclied to this last specimen : — 



" March Flies. Very common in Tasmania, especially in 

 sheep districts in the Midlands. Bite sharp, like the priclc 

 of a pin, and especially severe on childre!i, causing swelling 

 and sliglit inflammation. Nuisance has recently become so 

 severe as to interfere with school discipline. The least touch 

 kills the flics, and after school occasionally a shovelful can 

 be swept up.'' — Note by Dr. J. S. Turdy, Chief Health 

 Officer, llib.irt, 



Tahunus edetitulua, Macq., is possibly identical or very 

 nearly related to this species. Tubanus acutiijalpis, Macq., 

 appears very similar, but is larger in size. Both types are 

 in the Paris Museum. Tabanus fraterculus, Macq., is said 

 by the author to be related to T. edentulus (the type is lost) 

 from Tasmania. A rather variable species in colouring, it 

 may be distinguished from Tabanus imperfectus and Tabanus 

 antecedens by its larger size and more reddish colour of the 

 abdomen. The forehead is very slightly broader anteriorly 

 than it is at the vertex, contrary to the usual rule.

 white hairs, a few brown ones usually present on the centre.

 at base; it is rather broad at the base with a small tooth.

 often much denuded, appearing reddish or brown ; the 

 frontal callus almost square, reaching the eyes, with a lineal
