Netv Australian Tabanidae. 21 



tomentum. Forehead wider anteriorly, about three times as 

 long as broad anteriorly; clothed with grey tomentum, blackish 

 in middle, and with moderately sparse dark hairs ; callus black 

 shining, small transverse, not reaching eyes, with short linear 

 extension. Eyes with moderately dense short brown pubescence, 

 width across eyes less than the width of abdomen. 



Thorax black covered with grey tomentum, leaving three in- 

 distinct black lines, one median and two lateral, a short black 

 line also traceable on each side above wing roots; pubescence 

 white, scattered; long dark erect hairs also present, most numer- 

 ous anteriorly; shoulders grey; sides grey with long white hairs. 

 Scutellum black with grey border, and with a fringe of long 

 .rather scanty white hairs. 



Abdomen dark brown, first segment almost black, base of 

 •second segment and the segmentations rather broadly margined 

 with grey ; pubescence dark on basal portions, creamy white along 

 segmentations, the white hairs thickest at sides, and on a series 

 of apical median spots forming a more or less continuous median 

 stripe. Venter yellowish, darker at base of segments, with long 

 black semi-erect hairs and with finer decumbent creamy hairs 

 most marked on segmentations. 



Legs yellow, femora dark brown, almost black, with yellow 

 knees; tarsi infuscate, especially the anterior; pubescence on pos- 

 terior tibiae rather straggling and irregular. 



Wings hyaline, the veins very faintly margined with light 

 Thrown, slightly more distinct on cross veins; stigma and veins 

 brown, long appendix present. 



Hab. : — Tasmania, Dunally (seven specimens); Bream Creek 

 (two specimens). Collected by G. H. Hardy. 



Dates of collection, Dunally, 9-15/2/18; Bream Creek, 

 18-20/2/18. 



The coloration of the thorax varies somewhat, and might 

 1}e better described in the Bream Creek specimens as black, with 

 more 'or less distinct grey lines ; most of the specimens have, 

 however, the thorax as described, though greyish lines are trace- 

 able between the black stripes. 



The head is small as compared for example with specimens 

 •■■of T. edentulus of the same size. The size is also variable' rangr- 

 ing from 9.5 to 13 mm. 



I do not know of any previously described species with which 

 this can be confused. 



Type presented to Australian Museum, Sydney, by Mr. G. H. 

 Hardy.
