Female resembles the male very closely. Eyes not very 

 'widely separated. Thorax grey-brown. Abdomen long, 

 the second and third, and sometimes also the fourth, seg- 

 ment with a white hindmargin, the dorsum less covered 

 with grey tomentum than in the male. Legs and wings 

 ;&s in the male. 



This species is distinguished from the other members 

 -of the genus with wholly black femora, by its yellow wings 

 in conjunction with its small size and slender shape ; the 

 •only other known Tasmanian species with yellow wings 

 is A. montanus, a large mountain species with the middle 

 and hind femora wholly, and the front femora partly, 

 yellow. 



A. helvenacvs seems to show a fondness for the neigh- 

 bourhood of water, although it is not altogether confined 

 to such localities. I have found specimens of the female 

 frequenting a small marsh. The species occurs somewhat 

 sparingly, during the summer months, my dates ranging 

 from November IB to February 11. 



Anabarrhynchus terrenus, Sp. nov. 



A rather large species with brownish wings. Thorax 

 light yellow-brown or grey, with three dark brown stripes , 

 abdomen black, with hindmargins and lower corner's of 

 segments white; femora black, frequently reddish towards 

 the apex; tibiae yellow, yellow-brown, or red-brown; wings 

 "brownish. 



Length. Male, 8.5-10.5 mm. ; female, 10-12 mm. 



Hab. Bagdad Valley, Bellerive, Wedge Bay. 



Male. Face light grey. Front brown, with black hairs, 

 the frontal spots indistinct. Proboscis black, usually lying 

 close against the face. Antennas with first joint grey, bear- 

 ing black bail's, second and third black. Eyes separated, 

 but not very widely. Thorax light yellow-brown, with 

 three chocolate-brown stripes. Abdomen black, with hind- 

 margins and lower corners of second, third, and fourth 

 segments, and almost all the fifth segment, white, the 

 white portions being covered with short depressed white 

 pubescence. Legs with femora black, frequently becoming 

 reddish towards the apex, and sometimes also reddish 

 beneath ; tibia? yellow-brown or red-brown ; tarsi black. 

 Wings brownish. 



Female resembles the male, but the abdomen is longer, 

 and the eyes rather more widely separated. 



Variation. This species is subject to considerable varia- 

 tion, the specimens occurring near the coast being smaller 

 than those found in the bush inland, and having the
