Male. Face pale brown. Moustache scanty, consisting 

 ■of snow-white hairs, with about six isolated black hairs 

 above; beard white. Antennae black. Front brown. 

 Thorax black, with brown tomentum and whitish shoidder- 

 spots ; anterior half bare, posterior half with a few black 

 bristles; scutellum almost bare, but with two very weak 

 maririnal black bristles. Abdomen black, with orev tomeai- 

 tum, almost bare, but with short white side-bristle® on 

 posterior margins of each segment; genitalia, orange or 

 black. Legs with femora reddish-yellow, with a black 

 stripe above, th.at on the posterior pair sometimes reduced 

 to an elongated spot, but the shape and extent of these 

 black markings subject to great variation; tibiae reddish- 

 yellow, with apex black ; tarsi with first joint yellow, re- 

 maining joints black ; the femora are almost bare, but 

 have weak M'hite bristles below, and one or two bla.ck ones 

 near the apex above ; tibiae with a few scattered black, and 

 one or two white, bristles. AVings entirely hyaline, rilled, 

 but without any sign of inflation. 



FeiHdle resembles the male very closely, but is rather 

 more robust in shape, and the legs may be a little darker. 



This siDecies is readily recognised by the colouring of the 

 legs, which, even in dark specimens, have at least the lower 

 half of the femora, and a large part of the tibiae, reddish 

 yellow; by its small size, and hyaline wings without any 

 sign of inflation in either sex. As stated above, its occur- 

 j'ence in Tasmania is still open to some doubt.
