S. oedipus Fabricius. Milwaukee and Douglas Cos. 



S. pauper Loew. Specimens from Milwaukee Co. 



S. pluto Wiedemann. 1 specimen from Ellison Bay, Door Co., about 

 13 mm. long 1 , and 1 from Jacksonport, Door Co., 10 mm. long. In 

 the latter specimen there is a third, very small spot on the an- 

 terior branch of the third vein close to the margin of the wing, 

 which is distinctly developed in the right wing, hardly percep- 

 tible in the left. This species shows a great deal of variation 

 in the number and arrangement of the spots of the wings, a point 

 to which attention has been called by Osten Sacken (Western 

 Diptera, p. 244).
