pale brown, with a reddish tinge. Proboscis directed 

 inwards. Antennae nearly symmetrical, the first and sec- 

 ond joints and sometimes also base of the third brown, 

 remainder black ; the first two joints bear a little black 

 pubescence. Eyes hairy. Thorax olive-black, with four 

 dark grey stripes, which are sometimes indistinct, the 

 whole bearing black and a little white pubescence. Abdo- 

 men brownish-black, with hindmargins of segments light 

 brown, and a row of pale, clearly-defined centre spots ; 

 underside of abdomen with base grey, remainder pale red- 

 dish. Legs with femora black, the apex sometimes brown ; 

 tibiae brown ; tarsi brown or black ; pubescence of femora 

 white, with, sometimes, also a few black hairs ; pubescence 

 of tibiae white and black, none of the black hairs being 

 conspicuously longer than the others. Wings clear, ante- 

 rior veins light brown, with a light brown or yellow 

 stigma ; cubital fork with a recurrent veinlet. 



This species is not very easy to distinguish from T. ante- 

 cedens ; it is, however, a browner and more slender spe- 

 cies, with distinct abdominal centre-spots, and with the 

 base of the antennae lighter ; the vertex bears short instead 

 of long black hairs, the black pubescence of the hind 

 tibiae is of nearly equal length, instead of some of the 

 hairs being very much longer than the others, and the 

 stigma is more distinct, and pale yellow-brown instead of 

 black. From T. imperfectus it is distinguished by its 

 larger size, browner colouration, the short tibial pubes- 

 cence, and the yellower stigma. 



T. edentulu* is usually a common species in the bush 

 in the late summer. It is the last species of Tahanus to 

 appear on the wing. My dates range from. February 28 

 to March 15. It also occurs in Victoria. 



Tabanus imperfectus, Walk.

 men. Antennae with first joint grey, second grey or black, 

 third black ; thorax grey-black, with two light grey 

 stripes ; abdomen olive-black, with hindmargins of all seg- 

 ments, and (in the male) shoulders of second segment, 

 light grey; femora dark brown, tibiae olive-brown with 

 apex and tarsi black ; tibiae with long hairs on the inner 

 as well as the outer side ; wings clear, the stigma usually 

 indistinct.
