[Sept. 
with long, sparse, yellowish pile. The front is obscurely 
brownish yellow pollinose above; the eyes are separated 
by not quite twice the width of the anterior ocellus. Ver- 
tex opaque black, the pile of front and vertex long and 
black. The upper ocular pile is long, abundant and very 
dark brown to almost black ; the lower pile is more sparse 
and yellowish in color. The antennae are black, the third 
segment a little more elongate and perhaps from one and 
one-third to one and one-half times as long as wide. 
Arista dark reddish. The facial tubercle is well devel- 
oped but most abrupt below leaving the face gently con- 
cave above. Thorax: mesonotum dull opaque black with 
faint traces of a pair of brownish grey, submedial vittae 
anteriorly; the transverse suture is conspicuously bor- 
dered anteriorly by a linear band of yellowish white 
pollen. Behind the transverse suture the mesonotum is 
somewhat more obscurely opaque black fading away into 
very dark greyish black pollen. The mesonotal pile is 
yellowish on the anterior half becoming chiefly blackish 
posteriorly; the postcallar pile is almost entirely black 
with two or three yellow hairs. Scutellum opaque orange 
or rusty brown, the lateral corners narrowly blackish. 
The scutellar pile is long, erect and yellow except for a 
group of black hairs in each basal corner. Squamae dark 
brown. Legs: the femora are blackish becoming ob- 
scurely yellowish brown near the apex; the apex of the 
hind femora is subapically reddish. The hind femora are 
considerably thickened, the point of greatest thickness 
lies just beyond the middle. The anterior tibiae are 
blackish except the very narrow base which is yellowish 
brown. Middle tibiae light yellowish brown throughout. 
Hind tibiae slightly flattened with very little pile, the apex 
transverse, the base and apex light brownish red, the 
middle diffusely blackish but divided, except upon the 
narrow dorsal margin, by a conspicuous, light yellow tri- 
angle. Anterior tarsi blackish. The middle and hind 
tarsi upon the first three segments are brownish yellow 
but the medial margin of the hind basitarsi is dark brown ; 
remaining segments of these tarsi dark brown. Wings: 
quite hyaline with a strong stigmal cross vein. Ah do-
