S. similis, Wesm. — S distinguishable easily from p'^'- 

 f.oiis by its smaller, shorter form, the more swollen joints 

 of the flagellum, the narrow second submarginal cell, and 

 the concave lacinise of the armature ; as a rule all the 

 abdominal segments are spotted with black. 



? scarcely distinguishable from that of pilifrons, but as a 

 rule smaller, with the anterior tibite pale in front, the third 

 abdominal segment coarsely and remotely punctured at the 

 base, and with the area of the dorsal valve rather narrower, 

 and with a distinct marginal impression. I have looked in 

 vain for more satisfactory characters. 

 L. 6-8 mm.

S. ferruginatus, Schenck. — S differing from any of the 

 piccediiig in the deep groove at the base of the stipites of 

 the armature, it is very variable in colour and size, some 

 large examples being almost as wide in the abdomen as 

 the ? , and similarly coloured, others much narrower and 

 smaller, with all the abdominal segments banded with black, 

 the basal segment however is always more or less red ; the 

 mesonotum is very finely and closely punctured, joints of 

 the flagellum with narrow basal pubescent bands, genital 

 armature with the lacinia straight along its external margin, 

 which is slightly thickened at the npcx, which bears a few 

 long hairs, and with a triangular membraue on iis inner
