Fig. 35. Wing of Sisyrofui/ia auratn. 



Female. Face and front covered with golden pubes- 

 cence; vertex with a tuit of long black hairs. Antennae 

 black, the first joint about three times the length of the 

 second, and bearing long black hairs, the third consider- 

 ably longer than the first two together, strap-shaped, term- 

 inated by a small bristle-like style, and with one or two 

 long black hairs a little below the apex. Thorax black, 

 covered with short golden pubescence, and with long yel- 

 low and black hairs at sides and bordering the scutellum. 

 Abdomen black, with a broad median stripe of bright yel- 

 low pubescence, scattered golden pubescence, and abund- 

 ant long black hairs. Femora, tibiae, and first joint of 

 anterior and middle tarsi pale red ; remaining tarsal joints 

 and the whole of the posterior tarsi black ; posterior femora 

 beneath with a complete row of spine-like bristles; all 

 tibiae with bristles, but these are longest and stoutest on 

 the posterior pair; first joint of posterior tarsi fringed 

 with short bristles. Wings dark grey, with the base ferru- 

 ginous; discal cell large; radial vein boldly curved up to 

 the costal margin, which it meets at almost a right-angle. 



This fine insect is easily recognised by its golden ap- 

 pearance, bright yellow abdominal centre-stripe, and large 

 size. It was described by Walker from Western Australia 

 and Tasmania, but confirmation of its occurrence in Tas- 

 mania seems desirable. It also occurs not uncommonly 

 in South Australia.
