New Australian Tabanidae. ]& 



Abdomen dark brown, segmentations yellowish brown ; first 

 segment with grey pubescence, remainder with short decumbent 

 dark pubescence, and a fringe of yellowish brown hairs on seg- 

 mentations; venter similar, segmentations rather broader. Legs- 

 light yellowish brown, the posterior pair rather darker, tibiae 

 slightly darker at apices ; tarsi brown ; long spurs present on 

 posterior tibiae. 



Wings, grey, yellowish brown along the anterior border; veins, 

 brown, stigma brown, appendix present, all the posterior cells 

 open. 



Hab. : — Victoria, Mallee District. 



Described from a single female sent by the National Museum,. 

 Victoria. I have referred this species to Ectenopsis with a good, 

 deal of hesitation, the antennae are very similar to those of Para- 

 silz'ius, and the basal divisions of the third joint are very in- 

 distinct. The palpi are, however, different, and more like those: 

 of Ectenopsis, though shorter 'and more slender. Probably a. 

 new genus will ultimately have to be erected for its reception, 

 but I am unwilling to do so at present on a single female. The 

 coloration will readily prevent any confusion with the described 

 species of Ectenopsis. 



Type in National Museum, Victoria. 



Since the above description and notes were written, I have 

 received for examination two males belonging to the South Aus- 

 tralian Museum, which appear to me to belong to the same- 

 species as the Victorian female. There are some differences 

 which may, however, be sexual, and the specimens are certainly 

 too like E. victoriensis to be described as distinct, at least until' 

 a South Australian female can be obtained. 



Following is a short description of the males in so far as they 

 differ from the type female. 



cT Long: — 10-12 mm. 



Colour and clothing as in female ; eyes contiguous, bare, facets 

 equal ; ocelli distinct. Facial triangle reddish brown, clothed with 

 grey tomentum and with long bristle-like hairs, first joint short 

 and stouter than second; second short and ending in short point, 

 shorter and stouter than in female ; antennae rather more slender 

 than in $. and with apical annulus only dark, the third joint with 

 five distinct annuli and indistinct evidence of two further sub- 

 divisions, the apex of antennae with a group of short hairs. 



Thorax dark brown with evidences of three indistinct greyish- 

 tomentose stripes, clothed with upright brown hairs, sides with
