This species does not seem so confined to the neigh- 

 bourhood of water as the other Tasmanian species of 

 Hilara, but may be found skimming low o\'er the bare 

 ground. It is generally a common species. My dates 

 range from October 1 to December 31. 



Hilara balnearia, Sp. nov. {Pig. 41b.) 



Thorax and abdomen black; anterior tibi?e with long, 

 scattered, black, hair-like bristles; wings almost hyaline; 

 halteres dark brown. 



Length. Male, 3 mm. 



Hab. Hob art, Mangaloro. 



Male. Face and front black ; vertex with ^ong, black 

 bristles. Eyes separated. Proboscis stout, hardly as long 

 as the height of head. Antennae black, the first and sec- 

 ond joints short, the third rather more than twice tfie 

 length of the first two together, and terminated by a long, 

 slender style, which is a little mere than half its length. 

 Thorax black, unstripecl, with very long, scattered black 

 bristles ; scutellum with four marginal black bristles. Ab- 

 domen brownish-black, bare of pubescence, but with short 

 black terminal bristles. Legs dark brown, anterior tibiae 

 with long, scattered, black, hair-like bristles ; anterior 

 tarsi with the first joint considerably inflated, and bearing 

 a single, very long black hair on its inner side. Wings 

 faintly tinged with brown, and bearing a brown stigma ; 

 the mediastinal vein short, curved up at its end, and meet- 

 ing the ccsta; cubital fork long and narrow, the upper 

 branch nearly as long as the lower; anal vein fairly 

 long, and nearly reaching the wing-margin ; halteres dark 

 brown. 



This species frecjuents the neighbourhood of water ; it 

 is probably widely distributed, though hardly so common 

 as some of the other species. My dates range from Sep- 

 tember 24 to November 16. 



Hilara nimia, Sp. nov. (Fig. 41c.) 



Front tarsi in male with the first joint enormouslv dilat- 

 ed ; thorax velvet-black, abdomen brownish-black; wings 

 hyaline ; halteres yellow. 



Length. Male, 4.5-5 mm. 



Hab. Mangalore. (Probably generally distributed.) 



Male. Face and front black ; vertex with short, black 

 bristles. Eyes separated. Proboscis about the same 

 length as the height of head. Antennae black, the first 

 and second joints very short, the third a little more than
