■New Australian Tabanidae. 25 



Mr. Taylor has recorded T. brisbanensis also from Tasmania, 

 :at the same time pointing out certain differences between the 

 females, though he does not regard these differences as of speci- 

 fic value. There is a long series of a species very close 

 to T. rcgis-georgii among Mr. Hardy's Tasmanian Tab- 

 anidae, which probably are the same as the species Mr. Taylor 

 had from Tasmania. Though the females are very close, the 

 males present differences which appear to be certainly of 

 specific value. Further details will be found under the follow- 

 ing species : — 



Tabanus diEmanensis, n. sp. (Text Figures lb, 3.) 



Closely allied to T. regis-georgii, Macq., but differing in the 

 more finely facetted eyes of the male. 



& Long: — 10 mm., width of head 4 mm., wing 9 mm. 



Face and cheeks densely clothed with creamy yellow tomen- 

 tum, and with long brownish hairs; beard yellow. Palpi nearly 

 -as long as proboscis, second joint elliptical, yellow, set with long 

 hairs, creamy at base, brown nearer apex. Proboscis very short. 

 Antennae reddish brown, the first joint more greyish, and the 

 annuli blackish, first two joints with long hairs, yellowish on 

 undersurface of joints, brown above; third joint noticeably 

 shorter (though somewhat variable in length) than in T. regis- 

 georgii, with basal portion broader and more distinctly angu- 

 late, annuli shorter. Eyes contiguous, densely clothed with long 

 black hairs, with larger facettes occupying the upper and inner 

 two-thirds, becoming finer below, and also towards the upper 

 margin, these larger facettes noticeably smaller than the corres- 

 ponding ones in T. regis-georgii. 



Thorax with a broad median band from anterior margin to 

 middle, indistinctly divided by a narrow paler median stripe, 

 .and continued from middle as a narrow, dark median stripe, 

 also with narrower sublateral dark stripes and a short narrow 

 .stripe over each wing root, these dark stripes separated by nar- 

 rower grey stripes ; rather densely clothed with fine creamy de- 

 cumbent pubescence, and with longer erect brownish hairs ; rather 

 small creamy tufts of hairs present above wing roots; shoulders 

 with dark hair tufts; sides with tufts of long creamy yellow 

 hairs brownish in centre. Scutellum dark brown, the apical 

 margin grey, and fringed with long creamy hairs. 



Abdomen dark brown, the segmentations broadly banded with 

 lighter colour, varying from light brown to creamy, and forming
