 red, the posterior pair with a broad black band near the

Lciujth. Female, 6 mm. 



Hah. Eidsvold, Queensland. 



Feiiiah. Face and moustache silvery white, the 

 moustache consisting of a fringe of drooping bristle-like 

 hairs, which are confined to the oral margin ; front simi- 

 larly coloured to the face, with a small, black, much up- 

 standing occUar tubercle, which bears two small black 

 bristles. Thorax shining Ijlack, with short black pubes- 

 cence and black lateral bristles; scutellum black, 

 with about four very fine marginal hair-like bristles. 

 Abdomen deep blark, coarsely punctate, with short white 

 lateral bristles, and apex with long black hairs. Legs 

 with femora yellowish-red. the posterior pair with a broad 

 black band, which commences close to the base, and extends 

 to beyond the middle; anterior and middle tibije dull pale 

 brown ; posterior tibia? shining dark brown ; tarsi brown ; 

 the femora are practically bare, but the middle pair have 

 one, and the posterior pair two, black bristles on the upper 

 side, but this number may not be constant : tibia"- and 

 tarsi with numerous very long, black, hair-like bristles, and, 

 in addition, the posterior tibicie bear a remarkably long 

 black bristle on the upper side ; the tibise ai-e also provided 

 with a fringe of white pubescence on the lower side. Wings 

 tinged evenlv with brown ; the first posterior cell wide 

 open, the fourth closed considerably above the wing mar- 

 gin, the cross-vein closing it in an almost straight line 

 with that closing the discal cell ; anal cell closed. Halteres 

 yellowish-white. 



This species is easily distinguished from A. aiixf rails, 

 Ricardo, the only other known Australian species, by the 

 wings being evenly tinged with brown, instead of being 

 hyaline, with the wing-veins, and particularlv the base of 

 the cubital fork, being conspicuously suffused with 

 bi'own, by the femora being vellowish-red instead of black, 

 and by the abdomen being deep black instead of purple 

 or blue-black.
