Three males taken at Vancouver, April 13, 1906, by Mr. R. V. 

 Harvey. 



The species is easily distinguished from S. gracilis, Coquillett, which 

 also has a shining black face, by the presence of three yellow cross-bands 

 on the abdomen instead of one, by the yellow anterior legs and by the 

 facial tubercle, which is low instead of prominent.
