 furriness of the body. 



A female specimen from Namaqualand, Spektakel, October, 1890 

 (E. M. Lightfoot), measuring less than 9 mm. in length. I refer it to 

 the male of greater size (13 mm.) described by Loew in a few words 

 from Bloemfontein, chiefly on account of the dark furriness of the 

 body ; from ;S'. ansteni, Bezzi, from Rhodesia it is distinguished by 

 the non-ciliated third antennal joint and by the infuscated wings. 

 Occiput Avith yellowish hairs, frons and face with more infuscated 

 ones. Antennae entirely black, with the first joint more than twice 

 as Ions: as the second, and a little shorter than the third, which is of 

 elongate conical shape and quite bare. Proboscis entirely black. The 

 dullish black thorax and the shining reddish scutellum are clothed 

 with fuscous hairs and with black bristles. Sc^uamulae yellowish- 

 brown with a whitish fringe ; haltères with a white knob. Abdomen 

 black, rather shiny, with fuscous hairs and with very niunerous and 

 strong black bristles at hind border of the segments ; venter with pale 

 yellowish hairs at base ; anal tuft dirty whitish. Legs stout, entirely
