Tabanus Regis-Georgii, Maeq. 



This is one of the common species, found from the Tweed River, New 

 South Wales, to Cardwell, North Queensland. 



It measures slightly over half an inch in length from the front of the head 

 to the tips of the wings. It is of a uniform light-brown tint, marbled with 

 grey on the thorax, with the hind margins of the abdominal segments edged 

 with greyish white; the wings transparent, with the front (subcostal) area 

 shaded with brown. 



Tabanus nigro-pictus, Macq. 



This is a species found about the Richmond River, New South Wales. 

 It is a large fly, measuring nearly an inch in length; of a uniform reddish- 

 brown tint; the upper surface clothed with fine golden hairs, the under 

 surface with grey hairs. The eyes are lead colour; and the dorsal surface 

 of the thorax is mottled with black showing through the golden pubescence- 

 It resembles Tabanus sanguinarius in size and general colouration, but 

 differs in having darker markings upon the thorax. 



Tabanus concolor, Walker. 



This species has a wide range from Eastern Victoria to the Tweed 

 Hiver, New South Wales, and probably Southern Queensland. We have 

 specimens from Mount Kosciusko. 



It measures just under an inch in length from the front of the head to the 

 tips of the wings, and is of a uniform dark-lead colour. There are a few 

 cattered, short, white hairs on the sides of the thorax and along the apical 

 edge of the abdominal segments. The under surface of the head and 

 thorax is clothed with silvery long hairs, thickest below the mouth parts. 

 The wings have brown nervures, and are slightly clouded, darkest towards 

 the shoulders.
