distinct dark brown stigma ; mediastinal vein short, curved 

 up at it^ end, and meeting the costa; cubital fork long 

 and narrow, the upper branch almost ar> long as the lower ; 

 anal vein long, and almost reaching th© wing-margin; 

 halteres pale whitish-yellow. 



Female resembles the male, the thorax beirg similarly 

 striped; abdomen a lighter brown, and produced into a 

 long ovipositor; anterior tarsi not dilated, but thei first 

 joint long and slender, in length rather more than that 

 "of the remaining four joints together; wings paler than 

 in the m.ale. 



This species may be recognised without difficulty by 

 the conspicuously striped thorax. I found it frequenting 

 the rocks in the bed of a mountain stream at Hobart on 

 November 18, 1913; probably it occurs not uncommonly 

 in similar situations. 



xTlLARA MOLLICELLA, Sp. UOV. (Fig. 41e.) 



Thorax brown, with four faint brown stripes; legs a 

 uniform pale brown; wings practically hyaline, with a 

 faint stigma; halteres light brown; late autumn species. 



Length. Male, 3 mm. 



Hab. Mangalore. 



Male. Face and front black; vertex with black hairs. 

 Proboscis stout, about as long as the height of head. An- 

 tennae short, the third joint twice as long as the first and 

 second together, and terminated by a slightly thickened 

 style, which is nearly equal to it in length. Thorax brown, 

 with four faint, narrow, brown stripes ; dorsal bristles 

 of medium length, lateral bristles long; scutellum grey, 

 with four marginal black bristles. Abdomen brown, dark- 

 est towards the apex, and bearing a few short, black 

 bristles. Legs a uniform pale brown; anterior tibiae with 

 a few widely separated black bristles ; posterior tibiae 

 almost bare, but with a few short, black bristles; anterior 

 tarsi with the first considerably dilated, in shape a length- 

 ened oval, about equal in length to the remaining four 

 jointsi together. Wings practically hyaline, but with a. 

 faint brown tinge; the mediastinal vein short, curved up 

 gently at its end, and meeting the costa; cubital fork 

 long and narrow, the upper branch nearly as long as the 

 lower; discal cell more produced above than in H. niibila', 

 anal vein nearly reaching the wing margin. 



This species differs from all the other known Tasmanian 

 species of Hilara by occurring in the late autumn, in- 

 stead of in the spring time. I have only met with a single 

 specimen, which occurred at the side of a pond at Man- 

 galore, on April 26, 1914.
