Tabanus dlmhnttus, Walker, List Dipt. i. p. 183 (1818). 



Ty[)e (female), in poor preservation, from Port Essington, 

 N. Australia. 



This tvpe bears a very strong resemblance to Tabayius 

 avidua, Bigot, from Australia and Sydney, but is apparently 

 a distinct species, ihc pa/pi being stouter, the frontal callus 

 a different shaiie, and the tooth of antcnnal thinl joint is 

 smaller. The pa/pi are stout at base for quite half their 

 length, ending in a line sharp point, pale yellow in colour, 

 with chiefly yellowish pubescence. The antennce are tawny, a 

 little dusky at tip; the tooth is little more than an angle, at 

 the base of the third joint. I'orcluad slightly narrower 

 anteriorly, about six times as long as it is broad antcricu'ly ; 

 frontal callus dark brown, oblong, not reaching eyes, with a 

 lineal extension. Abdomen same colour as in 1'. avidus, with 

 the trace of a darker spot on the second segment ; apex 

 somewhat darker in colour. Leys wholly yellowish ; tarsi 

 dusky at tips. 



Length 13 mm. 



The state of the type precludes a fuller description. It is 

 distinguished from Tubanus niijnniaiius, Wlk., by the yellow 

 femora.
