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 8S. decorum. 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 q 
\Vashburn from the Minnesota Experiment Station Collection, 
hearing the label S. decorum proved to be S&S. vitta- 
tall Wie 2).

U. S. Nat. Mus. Proc. 25:96 
Eight female specimens received from Professor Aldrich of 
Moscow 1d. which I have examined, agree pretty well with 
Walker’s description of ochraceum, excepting that in no case is 
there 2 trace of black at tip of femora, the tarsi are only slightly 
darker than the tibiae, and not black, and the length, which ac- 
cording to Walker is 2mm, is nearly double that in these speci- 
mens. The description of the Idaho specimens is as follows: 
Deep yellow or 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, subcostal 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 pl.34, fig, of hirtipes. Venation as 
in hirtipes, the vein R,+, being present; but M,+, bends 
down into cell M,+, slightly more than in the wing just men- 
tioned. Length 3.5 to 4mm. Length of one wing 5mm. Ac-
