[Sept. 
and second antennal segments are black, the third very 
dark brown with reddish base. The arista is slender, 
bare and yellowish brown with white apex. The third 
antennal segment is short oval. The eyes are rather 
thickly covered with shining yellowish white pile. 
Thorax: the mesonotnm and humeri are black, feebly 
shining, heavily obscured with an orange brown pollen. 
There is a pair of snbmedial, rather wide, definite but 
indistinct, blackish vittae which run about three-fourths 
the length of the mesonotum; there is also a large spot 
anterior to the transverse suture and another wedge- 
shaped spot posterior to the transverse suture. These 
spots and vittae are also overlaid with brown pollen and 
they are only visible at certain angles. The scutellum 
is translucent, brownish orange with light brownish 
orange pile. The mesonotal pile is similar in color but 
seems to have less reddish tint and there are numerous 
fine black hairs interspersed upon the posterior half of 
the mesonotum. Pleura black, thinly yellowish pubes- 
cent on the posterior border of the mesopleura, the ster- 
nopleura and the anterior half of the hypopleura and all 
of the metapleura. Pleural pile orange above, nearly 
white below. Squamae yellowish brown, the halteres yel- 
low with brown stalk. Legs: black, the tarsal segments 
narrowly reddish brown in the middle of the apex. The 
hind femora are only moderately thickened, are long yel- 
low pilose medially and dorsally with a few reddish hairs 
along the middle of the lateral surface and with black 
pile or bristles ventrally on the apical half. The hind 
tibiae are arcuate and flattened ; they are black pilose on 
the apical half, medially, ventrally and dorsally but yel- 
low pilose throughout the entire length laterally. The 
pile of the anterior femora and tibiae is almost entirely 
black but is narrowly yellow along the anterior margin 
of each and posteriorly along the basal half of the femora. 
The middle tarsi are chiefly reddish brown with diffuse, 
central blackish areas on these tarsi dorsally. Wings: 
distinctly tinged with yellowish or reddish brown over 
the middle of the wing, more dilutely in the costal cell
