haired. Wings hyaline, with a slight grayish tinge; R, with setulae 
on stigmatal area more closely set than elsewhere. Squamae and 
halteres yellow. 
Abdomen yellow, becoming reddish yellow toward apex, marked 
with black as follows: a median rounded spot and sometimes a lateral 
spot on each side, on tergite 1; a triangular median spot, reaching 
basal third of segment, expanded into a complete posterior band dor- 
sally and extending over the sides ventrally, but not reaching the 
sternite, on tergite 2; a triangular median spot reaching almost to base 
of segment, expanded into a transverse band that occupies posterior 
fourth to half of tergite dorsally and extends onto the ventral surface 
to border broadly on the sternite, on tergite 3; and a posterior spot on 
each side that expands broadly into a posterior margin ventrally 
but not dorsally or tergite 4. Some soft yellowish hair ventrally on 
tergite 1; abdomen otherwise with coarse black hair. Tergites shining 
dorsally, with scattered yellowish pollen ventrally; tergites 2 to 4 
ventrally each with anterior margin of thick white pollen, which shows 
from dorsal view as small side spots on segments 3 and 4. No median 
marginals on first two abdominal segments.
