Fig. 23. Dacus {Strumeta) pulcher (Tryon): a, head, lateral; b, wing of male. 
is densely covered with grayish pubescence 
which is very indistinctly divided by three 
narrow, subshining longitudinal vittae. The 
lateral yellow stripes are narrow, extend from 
the suture to the inner supra-alar bristles, and 
are slightly discolored with brownish on the 
posterior half. The yellow coloring extends 
a short distance along the suture on each 
side. The scutellum has a broad black band 
across its base. The scutelJar bristles are about 
as widely spaced as the prescutellars. The 
yellow mesopleural stripe is almost parallel 
sided, just gradually expanding toward the 
top margin. The anterior half of each meso- 
pleuron is shining black. Legs: Coxae black, 
trochanters discolored with brown, legs other- 
wise yellowish-red. Wings: Costal band and 
cubital streak very broad and dark brown- 
fumose. The first two costal cells are con- 
colorous with the remainder of the costal 
band and very densely and completely 
covered with microtrichia. The costal band 
fills all of cell R 3 and extends a short distance 
below vein R4-1-5 on the outer half of that vein. 
The cubital streak fills all of the basal part of 
cell M 4 almost to the top margin of the m-cu 
crossvein and extends in a broad, almost 
parallel-sided band to the wing margin. A 
broad crossband extends obliquely through 
the middle of the wing. This runs from vein 
R4-1-5 at the r-m crossvein to the wing margin 
at the apex of vein M 3 -)- 4 . This takes in the 
r-m and m crossveins and fills all of the apical 
half of cell 1 st M 2 except for a triangular- 
shaped hyaline spot in the center of this por- 
tion (Fig. 23 ^). The r-m crossvein is straight 
but oblique in position; it is situated an- 
teriorly to the middle of cell 1 st M 2 and well 
before the apex of vein Ri-i- 2 . In the male the 
narrowed portion of the cubital cell is two 
times longer than the portion from the apex 
of the cell to the wing margin. Abdomen: 
Almost all black, the apical half of the second 
tergum whitish to yellowish, and the apical 
half of the fifth tergum rufous, discolored 
with brown to black on the anterior portion 
of this band. The integument is densely 
covered with minute punctules.
