In the report of the Minnesota Experiment Station, Bulletin 

 48, 1896, page 202, is given a figure of a female fly which is said 

 to be S. d e c o r u m . In this figure the thorax is represented 

 as unicolored, the abdomen with the anterior half of the second 

 segment, a semicircular spot on the anterior margin of the seg- 

 ments 3, 4 and 5, a blotch on the sixth, and all of the remaining 

 segments dark; legs dark, excepting the middle section of all the 

 tibiae, a part of the middle and hind femora, and the basal two' 

 thirds of the hind metatarsi. No description is given, but the 

 author stated that this fly occurs in large numbers in Minnesota 

 during June and July. Some specimens kindly lent by Mr 

 Washburn from the Minnesota Experiment Station Collection, 

 h( iuiug the label S. decorum proved to be S. vitta- 

 1 u ni ( ? ).

Eight female specimens received from Professor Aldrich of 

 Moscow Id. which I have examined, agree pretty well with 

 Walker's description of ochraceum, excepting that in no case is 

 thej'o a trace of black at tip of femora, the tarsi are only slightly 

 darker than the tibiae, and not black, and the length, wiiich ac- 

 cording to Walker is 2mm, is nearly double that in these speci- 

 mens. The description of the Idaho specimens is as follows: 



Deep yt>ll()w oi ochraceous; the head, upper surface of an- 

 tennae particularly at the incisures and the two basal joints, 

 the mouth parts, sides of thorax at the base of the wing, the 

 abdomen except the basal segments the tips of the tibiae and 

 all the tarsi, particularly the fore and middle pair, and their 

 flexor surfaces, and the hind metatarsi, more dusky than else- 

 where. In fact, in some specimens the tarsi and the abdomen 

 may be described as blackish. The head, dorsum of thorax and 

 abdomen are covered with short, sparse, pale yellowish pile. 

 Legs are without long hair; all tibiae with spurs; the tarsal 

 claws simple. Halteres dusky yellow. Wings hyaline, slightly 

 blackish at tip, subco^stal cell yellow, the veins yellow except 

 the apical half of the veins of the anterior margin, which are 

 blackish. A yellow cloud follows the course of the media and 

 the anal veins, as in p].34, fig.l, of hirtipes. Venation as 

 in hirtipes, the vein B.^+., being present; but M^-i-j bends 

 down into cejl M^+g slightly more than in the wing just men- 

 tioned. Length 3.5 to 4mm. Length of one wing 5mm. Ac-
