228 THE DIPTERA-BRACriYCERA OF TASMANIA, 



This species frequents pools of water like the species 

 of Hilaru ; it seems to be rather uncommon. My dates 

 range from November 17 to November 30. 



HiLAROPUs NiGRiMANus, Sp. nov. (Fig. 42b.) 



Thorax and abdomen dark brown, the abdomen hairy ; 

 front tibice with long hairs at apex ; anterior tarsi in the 

 male with first joint much dilated; wings with veins dark 

 and distinct. 



Length. Male, 3 - 3.5 mm. 



Hab. ]\Iangalore. 



Male. Face and front black: vertex with long, black 

 bristles. Eyes separated. Proboscis in length about the 

 height of head. Antennae rather longer than the head, 

 the first and second joints very small, the third slender, 

 about twice as long as the first two together, and termin- 

 ated by a slender style, which is about half its length. 

 Thorax brown, unstriped, thoracic bristles of medium 

 length; scutellum w^th six marginal bristles, the two 

 middle ones the longest, the two outer short ; metapleura 

 without bristles. Abdomen brown, with long, black, lat- 

 eral pubescence. Legs entirely brownish-black, anterior 

 tarsi with the first joint great dilated; anterioi- tibiae with 

 a tuft of long, black hairs on the outer side close to the 

 apex ; middle and posterior tibiae with a thin fringe of 

 black hairs; posterior femora with scattered black hairs. 

 Wings brownish, the mediastinal vein straight, becoming 

 evanescent at its tip, and not reaching the costa ; cubital 

 fork fairly long, but not narrow; veins of wing dark 

 brown and distinct; halteres dark brown. 



This species may be met with commonly in the early 

 spring, skimming the surface of pools of water in com- 

 pany with Hilara niinia. My dates range from August 

 17 to September 1, but it j^robably remains on the wing 

 until later date. 



HiLAROPUs PEREGRiNUS, Sp. uov. (Fig. 42c and 43.) 



Male with thorax velvet-black ; abdomen with first seg- 

 ment black, remaining segments covered with pale blue 

 tomentum. Female with thorax pale grey, flushed above 

 with red, and bearing four very distinct black stripes, the 

 two median ones narrow, the two lateral ones broad, and 

 interrtipted in the middle ; abdomen black, with only a 

 faint trace of the blue tomentum of the male. Halteres 

 yellow. 



Length. Male, 6-7 mm.; female, 7 mm. 



Hab. Bagdad Valley. (Probably generally distributed.)
