 the apical half, the basal half with closer and smaller pili-

 middle, as in ^S*. ruficornis ; thorax finely and closely punc- 

 tured. First dorsal segment much more finely punctured

This is very near S. ruficornis, but differs much in the 

 colour of the wings and abdomen. The sixth dorsal segment 

 is also more finely and sparsel}'' punctured, and is rather 

 more narrowly rounded at the apex, and the pygidial area 

 more clearly defined. The punctures of the clypeus are also 

 less distinct.
