rupted slightly at the suture. The median 
vitta is expanded on the anterior part of the 
mesonotum. In some specimens the black 
coloring broadly covers the front portion of 
the dorsum, occupying much of the medial 
part beyond the suture. In others it forms 
just a T-shaped pattern behind the bases of 
the scapular bristles. The area of the mesono- 
tum between and outside the black markings, 
excepting the lateral yellow stripes, is reddish 
in color and densely gray pollinose. The yel- 
low stripes are very short; they do not extend 
to the inner supra-alar bristles. The scutellum 
is all yellow except for a very narrow black 
band across its base. The pleura are yellow to 
rufous, except for the predominantly black 
sternopleura and for a black spot on the front 
of the mesopleura and sternopleura, a spot on 
the hypopleura, and one on the lower margin 
of the metapleura. The metanotum is black 
except for a red spot in the central portion. 
The vertical yellow stripe on the mesopleura 
is expanded on the dorsal portion and extends 
anteriorly to a point opposite the anterior 
notopleural bristles. Legs: Yellow, except for 
the brownish hind tibiae. Wings: First two 
costal cells hyaline, devoid of microtrichia ex- 
cept in the apex of the second cell. Costal 
band distinct, brownish, not extending 
noticeably below vein R3 except along the 
wing margin. The band is not expanded in the 
apex and extends halfway through cell R5. 
The r-m crossvein is straight and nearly 
vertical in position. It is situated distinctly 
beyond the middle of cell 1st M2. The cubital 
streak is broad, filling all of the basal portion 
of cell M4 and extending nearly to the top 
margin of the m-cu crossvein. The narrowed 
portion of the cubital cell is two and one-half 
times longer than the portion from the apex 
of the cell to the wing margin. Abdomen: 
Nearly all reddish except for a black vitta 
extending down the middle of terga 3 to 5. 
The base of the third tergum possesses a 
narrow black crossband in some specimens 
but is brownish in others. The first tergum is 
brownish on the basal portion and yellow-red
