[Sept. 
fluent with the narrow and similarly pubescent eye mar- 
gins. The pile on the anterior part of the raised ocella- 
rium is black; upon the posterior portion it is yellow. 
The occipital pile is brassy yellow with some slender 
black hairs above lying anterior to the yellow ones. 
The ocular pile is slightly flattened, moderately abun- 
dant and brilliantly shining silvery with perhaps a faint 
yellowish cast. The first segment of the antenna is black, 
the second almost black ; both are black pilose. The third 
segment is comparatively short compared to other spe- 
cies of this genus; it is distinctly wider basally and 
viewed from the outside this segment is about one and 
one-third times as long as its greatest width. The third 
segment is narrowly reddish basally but otherwise black ; 
it has a large, medial, basal, ventral pore. The arista is 
light brownish yellow throughout; the apex quite fine. 
Thorax: mesonotum shining black with a pair of dull, 
rather well separated, brownish grey pollinose vittae situ- 
ated in the middle of the mesonotum which are distinct 
for only a short distance beyond the transverse suture. 
The humeri are a deep reddish brown with a large, 
rounded patch of dense, pale yellow pubescence upon the 
medial portion. This patch does not extend to the pos- 
terior part of the humeri. Between this patch of pubes- 
cence and the medial grey stripes there is an opaque 
black spot which fades out diffusely behind and which 
has a very short, diffuse, posterior extension bordering 
the grey vittae and an equally obscure diffuse extension 
partially encircling the humeri. The scutellum and post- 
calli are very dark reddish brown and shining with short, 
erect yellow pile on each. The mesonotal pile is quite 
short and golden or brassy yellow but over the wing there 
is a wide dense patch of black setae. The notopleura and 
a small spot behind the suture are covered with a dense 
tuft of curly yellow long pile. Pleura black with long 
curly yellow pile on the mesopleura and thick yellow pile 
and pubescence on the pteropleura, sternopleura and 
hypopleura. Squamae nearly white with dark brown bor- 
der and fringe. Halteres orange on both knob and stalk. 
Legs : the femora are black, the apices of the anterior
