[Sept. 
of this band is straight. There is a minute, narrow patch 
of similarly colored tomentnm on the medial half of the 
transverse suture separated from the diagonal hand by 
a distance equal to its own length. In an oblique light 
the anterior diagonal yellow band is bordered by a wide, 
extensive, jet black, opaque stripe which occupies the full 
width between this diagonal band and the slender, medial 
sutural band. There is a similar band of creamy yellow 
tomentum just in front of the suture covering the pos- 
terior ends of the postcalli and expanded medially but 
gradually until it is about twice as thick as laterally. 
The scutellum is deep black with short, dense, black pile 
and a few longer pale hairs. The extreme posterior mar- 
gin of the scutellum is yellowish brown but this can 
scarcely be seen from above. Pleura black, the posterior 
margin of the mesopleura and all of the remaining pleura 
except the posteroventral half of the hypopleura thinly 
yellowish white pollinose. There is a vertical middle 
hand of only moderately long but thick white pile on the 
pleura. Squamae smoky brown in color with nearly white 
fringe and dark brown border. Halteres orange. Legs: 
all of the femora are black to the apex except the hind 
femora. On the hind femora the ventral apical third, 
half way up the sides, and at the extreme apex, is yel- 
lowish brown ; this color diffusely merges into the black 
of the remainder. The anterior and middle tibiae and 
their tarsi are entirely black. The hind tibiae are black 
except upon the basal ventral half. The hind tarsi are 
black. Coxae and the lower and basal portions of the 
hind femora with long, thick, crinkly pile, pale yellow 
except in the middle of the femora where it is brownish. 
The ventral apical third of the hind femora also is thickly 
beset with short, fine, black bristles. Pile of the hind 
tibiae and their tarsi pale yellow except that in the middle 
of the hind tibiae ventrally the yellow is mixed with con- 
siderable long, dark brown pile. Wings: mostly hyaline. 
The subcostal cell proximal to the stigmal cross vein, the 
basal half of the marginal cell and all of the submarginal 
cell, except the loop, are pale smoky brown in color. The 
anterior margin of the second longitudinal vein is nar-
